The material tray transfer device 40 provided in this embodiment realizes the automatic transfer process of the material tray 130 from the supporting component 401 to the material receiving position through the mutual cooperation of the lifting component 402, the grabbing component 403 and the moving component 404, thereby effectively improving the transfer efficiency of the material tray 130.

In addition, it should be noted that the tray transfer device 40 provided in this embodiment can also realize the reverse transfer process of the tray 130 from the receiving position to the bearing component 401 (i.e., the unloading process of the tray 130) under the cooperation of the lifting component 402, the grabbing component 403 and the moving component 404. The details will be explained in the subsequent description.

In this embodiment, as shown in FIG. 2 , the bearing assembly 401 includes a bearing frame 4011 and a second lifting member 4012, wherein the bearing frame 4011 includes a plurality of bearing pallets 40111 spaced apart along the Z-axis direction, each bearing pallet 40111 is used to bear the material tray 130, the output end of the second lifting member 4012 is connected to the bearing frame 4011, and the second lifting member 4012 is used to drive the bearing frame 4011 to move up and down along the Z-axis direction. The structural design of the bearing frame 4011 increases the capacity of the bearing frame 4011 for the material tray 130, and satisfies the bearing effect of multiple material trays 130. In addition, by providing the second lifting member 4012 to drive the carrier 4011 to move up and down along the Z-axis direction, it is convenient to adjust the material tray 130 to be transferred on the carrier 4011 to a desired height position, so that the subsequent grabbing assembly 403 can grab the material tray 130 to be transferred, and it is also convenient to adjust the empty carrying pallet 40111 to a desired height position, so that the empty carrying pallet 40111 can receive the material tray 130 grabbed by the grabbing assembly 403. Specifically, the second lifting member 4012 is a cylinder, which has the advantages of reliable and accurate driving.

In this embodiment, as shown in FIG2 , the carrier 4011 further includes two position limiting mounting plates 40112, which are arranged relatively spaced apart along the X-axis direction, and the plurality of bearing pallets 40111 are connected between the two position limiting mounting plates 40112. By providing the two position limiting mounting plates 40112, the positioning effect of the material tray 130 carried by the bearing pallet 40111 along the X-axis direction is achieved, thereby ensuring the accurate placement of the material tray 130 on the carrier 4011.

2, the carrier 4011 further includes a bottom plate 40113, which is connected between the two limit mounting plates 40112 and is located at the bottom of the entire carrier 4011. The structural design of the carrier 4011 ensures the structural stability and reliability of the entire carrier 4011.

It should be noted that, in the present embodiment, each bearing support plate 40111 includes two overlapping flat plates 401111 spaced apart along the X-axis direction, the overlapping flat plates 401111 are fixedly connected to the limiting mounting plate 40112 on the corresponding side, and the two overlapping flat plates 401111 jointly support the material tray 130. The structural design of the above-mentioned bearing support plate 40111 not only reduces the material cost, but also facilitates the grasping assembly 403 to directly extend into the bottom of the material tray 130 to grasp the material tray 130. It should be noted that, in the present embodiment, when the material tray 130 needs to be placed on the bearing support plate 40111, the material tray 130 can be directly pushed into the bearing support plate 40111 of the corresponding height along the positive direction of the Y-axis.

In addition, as shown in Figure 2, the supporting assembly 401 provided in this embodiment also includes a mounting base 4013, the second lifting member 4012 is installed on the mounting base 4013, and the lifting assembly 402 is also installed on the mounting base 4013.

In this embodiment, as shown in FIG. 2 , the material tray transfer device 40 further includes a limit assembly 406, which is mounted on the mounting base 4013 and is located on one side of the carrier 4011 along the positive direction of the Y axis. The limit assembly 406 can abut against one side of the material tray 130 carried by the supporting plate 40111 along the positive direction of the Y axis to limit the material tray 130 from being pushed into the extreme position on the supporting plate 40111 along the positive direction of the Y axis, thereby achieving the positioning effect of the material tray 130 on the supporting plate 40111 along the Y axis. It should be noted that when the material tray 130 is pushed onto the supporting plate 40111 from the side of the supporting plate 4011 along the negative direction of the Y axis, since the limit assembly 406 is located on one side of the supporting plate 4011 along the positive direction of the Y axis, when the pushed-in material tray 130 abuts against the limit assembly 406, it is proved that the material tray 130 is pushed into place.

In this embodiment, the limiting assembly 406 includes a lifting cylinder and a limiting rod, wherein the lifting cylinder is installed on the mounting base 4013, the output end of the lifting cylinder is connected to the limiting rod, the lifting cylinder is used to drive the limiting rod to move up and down along the Z-axis direction, and the limiting rod can abut against one side of the material tray 130 carried by the supporting plate 40111 along the positive direction of the Y-axis. When the material tray 130 is pushed onto the supporting plate 40111, at this time, the lifting cylinder drives the limiting rod to move up and down along the positive direction of the Z-axis, thereby ensuring that the limiting rod achieves the limiting effect on the material tray 130. After the limiting of the material tray 130 is completed, the lifting cylinder drives the limiting rod to descend and reset along the negative direction of the Z-axis to avoid interference with the subsequent transportation operation of the material tray 130.

In this embodiment, as shown in FIG. 2 , the lifting assembly 402 includes two lifting members 4021 arranged opposite to each other along the X-axis direction, the two lifting members 4021 are respectively located on opposite sides of the material tray 130 along the X-axis direction, and the two lifting members 4021 are both mounted on the mounting base 4013. Each lifting member 4021 includes a lifting driving member 40211, a clamping driving member 40212, and a lifting clamping claw 40213.

When it is necessary to transfer the material tray 130 on one of the supporting plates 40111 to the material receiving position, the two clamping drive members 40212 synchronously drive the corresponding lifting claws 40213 to move closer to each other along the X-axis direction, so that the two lifting claws 40213 clamp the material tray 130 together; then, the two lifting drive members 40211 synchronously drive the corresponding clamping drive members 40212 to rise to a preset height in the positive direction of the Z-axis, so that the material tray 130 clamped by the two lifting claws 40213 is lifted to a preset height; then, the moving component 404 drives the grasping component 403 to move until the grasping component 403 moves to the lifted height. The bottom of the tray 130; then, the two lifting drive members 40211 synchronously drive the corresponding clamping drive members 40212 to descend and reset along the negative direction of the Z axis, so as to place the tray 130 clamped by the two lifting claws 40213 in the grabbing assembly 403. After the grabbing assembly 403 completes the grabbing operation on the tray 130, the two clamping drive members 40212 synchronously drive the corresponding lifting claws 40213 to move away from each other along the X-axis direction to disengage the clamping of the tray 130, so as to facilitate the moving assembly 404 to drive the grabbing assembly 403 to reset and transfer the tray 130 grabbed by the grabbing assembly 403 to the receiving position. It should be noted that when it is necessary to transfer the tray 130 loaded with the transfer box 110 at the receiving position to the carrying pallet 40111, it is the reverse process of the above-mentioned operation process, which will not be repeated here. It should be noted that, in the present embodiment, both the lifting driving member 40211 and the clamping driving member 40212 are cylinders, which have the advantages of reliable and precise driving.

The positioning component 405 is used to locate the position of the material tray 130 grasped by the grasping component 403 along the X-axis direction, thereby ensuring that the material tray 130 is accurately transferred to the working position.

In this embodiment, as shown in Figure 3, the positioning assembly 405 includes a positioning drive (not shown in the figure) and two positioning clamps 4051, wherein the positioning drive is installed on the mounting base 4041, and the two positioning clamps 4051 are arranged relatively to each other along the X-axis direction. The two positioning clamps 4051 are respectively located on the opposite sides of the material tray 130 along the X-axis direction, and the output end of the positioning drive is connected to the two positioning clamps 4051, and the positioning drive is configured to drive the two positioning clamps 4051 to move closer to or away from each other. Specifically, when the linear transfer module 4042 drives the material tray 130 grasped by the grasping component 403 to move between the two positioning clamps 4051, at this time, the linear transfer module 4042 first stops driving the grasping component 403, and the positioning drive component synchronously drives the two positioning clamps 4051 to approach each other until the two positioning clamps 4051 are in contact with the material tray 130. When the positioning component 405 completes the positioning of the material tray 130, the positioning drive component synchronously drives the two positioning clamps 4051 away from each other. At this time, the linear transfer module 4042 continues to drive the grasping component 403 to move until the material tray 130 grasped by the grasping component 403 is moved to the working position. It should be noted that the positioning drive component is a finger cylinder, and under the action of the grasping component 403 grasping the material tray 130, the positioning component 405 can also drive the material tray 130 to move and adjust relative to the grasping component 403 along the X-axis direction.

In order to facilitate understanding of the tray transfer device 40 disclosed in this embodiment, the specific working process of the tray transfer device 40 is described in conjunction with FIG. 2 and FIG. 3:

When it is necessary to transfer the material tray 130 on one of the supporting pallets 40111 to the material receiving place, first, the second lifting member 4012 drives the supporting frame 4011 to move up and down until the material tray 130 to be transferred is lifted to a height position flush with the lifting claw 40213; then, the two clamping driving members 40212 synchronously drive the corresponding lifting claws 40213 to move closer to each other along the X-axis direction, so that the two lifting claws 40213 clamp the material tray 130 together; then, the two lifting driving members 40211 synchronously drive the corresponding The clamping drive member 40212 rises to a preset height along the positive direction of the Z axis, so that the material tray 130 clamped by the two lifting claws 40213 is lifted to a preset height; then, the linear transplanting module 4042 drives the grabbing assembly 403 to move along the Y axis until the grabbing assembly 403 moves to the bottom of the lifted material tray 130; then, the two lifting drive members 40211 synchronously drive the corresponding clamping drive members 40212 to descend and reset along the negative direction of the Z axis, so as to place the material tray 130 clamped by the two lifting claws 40213 on the fixed gripping member 4042. Then, the grabbing drive 4033 drives the movable grabbing plate 4032 to move along the Y-axis direction, so that the movable grabbing plate 4032 and the fixed grabbing plate clamp the material tray together along the Y-axis direction; when the grabbing assembly 403 completes the clamping of the material tray 130, the two clamping drive members 40212 synchronously drive the corresponding lifting claws 40213 to move away from each other along the X-axis direction to disengage the clamping of the material tray 130; then, the linear transplanting module 4042 drives the grabbing assembly 403 to move in the direction away from the carrying assembly 401. When the material tray 130 grabbed by the grabbing assembly 403 moves between the two positioning clamps 4051, at this time, the linear transfer module 4042 stops driving, and the positioning drive drives the two positioning clamps 4051 to approach each other, so as to realize the positioning of the material tray 130 along the X-axis direction; when the positioning is completed, the positioning drive drives the two positioning clamps 4051 away from each other, and the linear transfer module 4042 continues to drive the grabbing assembly 403 to move and reset in the direction away from the supporting assembly 401 until the material tray 130 is transferred to the material receiving position. It should be noted that after the material tray 130 completes the work at the material receiving position, the material tray transfer device 40 is required to transfer the material tray 130 at the material receiving position to the supporting assembly 401 to complete the unloading of the material tray 130. Since this process is the reverse process of the above process, it will not be repeated here.

Further, as shown in Figure 4, the material box loading device 10 includes a material storage component 101, a temporary storage platform 102 and a plurality of pushing components 103, wherein a plurality of material storage magazines 1014 are arranged at intervals in the material storage component 101, and the material storage magazines 1014 are used to store a plurality of empty transfer boxes 110 stacked in sequence along the Z-axis direction, and a temporary storage position is arranged on the temporary storage platform 102, and a plurality of pushing components 103 are all arranged on the temporary storage platform 102, and the plurality of pushing components 103 are arranged one-to-one with the plurality of material storage magazines 1014, and the pushing component 103 can push a transfer box 110 at the bottom of the corresponding material storage magazine 1014 to the temporary storage position.

The material box loading device 10 provided in this embodiment is provided with a plurality of pushing components 103, and the plurality of pushing components 103 are provided in one-to-one correspondence with the plurality of material storage magazines 1014, so that the operation of simultaneously loading a plurality of empty transfer boxes 110 at the temporary storage position can be satisfied, which greatly improves the loading efficiency of the transfer boxes 110, and the temporary storage position can realize the temporary storage of the loaded transfer boxes 110, which is convenient for the subsequent grabbing action of the transfer boxes 110. In addition, the plurality of pushing components 103 can independently perform the pushing action, so that the required pushing components 103 can be selected according to the demand to perform the pushing action, and the number of materials loaded to the transfer boxes 110 at one time can be flexibly changed, so that the loading method of the transfer boxes 110 is more flexible. And the material box loading device 10 realizes the loading by pushing the material at the bottom, and the structure is simple.

It should be noted that, in the present embodiment, since each material storage magazine 1014 can store a plurality of transfer boxes 110 stacked in sequence along the Z-axis direction, the storage capacity of the material storage assembly 101 is greatly improved, and the number of transfer boxes 110 stacked in sequence in each material storage magazine 1014 can be set according to specific needs. In addition, it should be noted that, after the material pusher assembly 103 completes the push-out operation of a transfer box 110 at the bottom of the material storage magazine 1014, the remaining transfer boxes 110 in the material storage magazine 1014 move downward under the action of gravity, so that the material pusher assembly 103 pushes out the next transfer box 110 at the bottom of the material storage magazine 1014.

Now, the specific structure of the material storage assembly 101 is described in conjunction with FIG. 4 . As shown in FIG. 4 , the material storage assembly 101 includes a silo body 1011 and a plurality of partition plates 1012, wherein a material storage cavity is provided in the silo body 1011, and a plurality of partition plates 1012 are arranged at intervals in the material storage cavity, and the plurality of partition plates 1012 are configured to separate the material storage cavity into a plurality of material storage magazines 1014. In addition, it should be noted that the silo body 1011 is a rectangular frame structure, which makes the structure of the material storage assembly 101 simple and also ensures the structural stability of the entire material storage assembly 101.

In the present embodiment, as shown in Figure 4, the material bin body 1011 is provided with an opening connected to the material storage chamber, and the material storage assembly 101 also includes a blocking door 1013, which is pivotally connected to the material bin body 1011, and the blocking door 1013 can block or open the opening. By setting the blocking door 1013, when it is necessary to replenish the transfer box 110 in the material storage magazine 1014, the blocking door 1013 can be opened. After completing the material replenishment operation of the material storage magazine 1014, the blocking door 1013 can be blocked to ensure the stability and reliability of the material storage magazine 1014 for the transfer box 110. It should be noted that in the present embodiment, the blocking door 1013 is in the form of a double door, and the blocking door 1013 can be locked in the blocking position of the blocking opening by magnetic attraction. In other embodiments, after the blocking door 1013 blocks the opening, the blocking door 1013 can be locked in the blocking position of the opening by means of an external door lock.

In this embodiment, as shown in Figure 4, the temporary storage platform 102 is connected to the bottom of the material storage component 101, and a pushing port is provided at the bottom of each material storage magazine 1014. A transfer box 110 at the bottom of the material storage magazine 1014 is located at the pushing port. The temporary storage platform 102 includes a supporting plate 1021, and a plurality of pushing chutes 10211 are spaced apart on the supporting plate 1021. Each pushing port is located in a corresponding pushing chute 10211, and the pushing chute 10211 extends along the direction in which the transfer box 110 is pushed, and the end of each pushing chute 10211 is a temporary storage position. The above arrangement enables that when the pushing assembly 103 pushes the transfer box 110 at the corresponding pushing port, the pushed transfer box 110 can slide along the pushing chute 10211 all the way to the temporary storage position, thereby providing a guide for the discharging action of the transfer box 110 and ensuring that the transfer box 110 can be pushed to the temporary storage position more reliably.

In addition, as shown in FIG4 , the temporary storage platform 102 provided in this embodiment further includes a limit plate 1022, which is connected to the carrier plate 1021. The limit plate 1022 can abut against the transfer box 110 in the temporary storage position to limit the limit position of the transfer box 110 sliding along the material pushing chute 10211. By providing the limit plate 1022, the pushed transfer box 110 is prevented from falling from the end of the material pushing chute 10211, ensuring that the pushed transfer box 110 is positioned at the temporary storage position.

The specific structure of the pusher assembly 103 is described in conjunction with FIG4 . As shown in FIG4 , the pusher assembly 103 includes a pusher cylinder 1031 and a pusher block (not shown in the figure). The pusher cylinder 1031 is arranged on the temporary storage platform 102. The pusher block is connected to the output shaft of the pusher cylinder 1031, and the pusher block can abut against a transfer box 110 at the bottom of the corresponding storage magazine 1014. By setting the pusher block to abut against the transfer box 110, the contact area between the pusher assembly 103 and the transfer box 110 is effectively increased, and the reliability of pushing the transfer box 110 is ensured.

In this embodiment, as shown in Fig. 4, the pusher assembly 103 further includes a first guide rail 1032, which extends in the direction in which the transfer box 110 is pushed, and the first guide rail 1032 is slidably connected to the pusher block. The above arrangement prevents the pusher block from deviating during the pushing process, ensures the stability and reliability of the moving direction of the pusher block, and further ensures the reliability of the pusher block in pushing the transfer box 110.

In this embodiment, as shown in FIG. 4 , the material box loading device 10 further includes a material detection component 104 , which is signal-connected to the push cylinder 1031 , and is used to detect whether a transfer box 110 is stored at the temporary storage location. Specifically, the material detection component 104 can be a sensor, and each temporary storage position is correspondingly provided with a material detection component 104. The material detection component 104 is connected to the corresponding push cylinder 1031 by signal. When the material detection component 104 detects that there is a transfer box 110 at the corresponding temporary storage position, the push cylinder 1031 does not operate according to the detection information of the material detection component 104; when the material detection component 104 detects that there is no transfer box 110 at the corresponding temporary storage position, the push cylinder 1031 can push the material according to the detection information of the material detection component 104. If the material detection component 104 detects that there is still no transfer box 110 at the corresponding temporary storage position after the push cylinder 1031 pushes the material, the material detection component 104 can issue a warning to facilitate timely replenishment of the corresponding storage magazine 1014.

In this embodiment, as shown in FIG4 , the material box loading device 10 further includes a support assembly 105, which is fixed on the table surface of the workbench 60, and is connected to the bearing plate 1021 of the temporary storage platform 102, and is used to support and fix the entire material box loading device 10. Specifically, the support assembly 105 can be in the form of a support frame or a support seat.

Further, as shown in FIG. 5 and FIG. 7 , the transfer mechanism 202 includes a transfer platform 2021, and storage areas 2022 are provided at opposite ends of the transfer platform 2021. The storage areas 2022 are provided with a plurality of storage slots 2023, and the storage slots 2023 are configured to place the transfer boxes 110. The transfer platform 2021 can rotate so that the storage areas 2022 at both ends are sequentially oriented toward the storage bracket 201. The needle matching assembly 203 includes a pick-up and placement member 2031, and the pick-up and placement member 2031 is configured to move a plurality of different types of drill needles 120 in different storage boxes 100 on the storage bracket 201 to one of the transfer boxes 110 on the storage area 2022 of the transfer platform 2021 close to the storage bracket 201. Among them, the transfer platform 2021 is driven to rotate by a servo motor driving a hollow rotating platform. The pick-up and placement member 2031 can be a clamp, a suction nozzle, or other structures, as long as it can pick up and place the drill needle 120, which will not be repeated here.

As shown in Figure 6, in the needle matching device 20, the storage bracket 201 is used to place multiple storage boxes 100, and each storage box 100 contains multiple drill needles 120 of the same model. The needle matching assembly 203 can select the drill needles 120 of corresponding models and quantities as needed, and move them from the storage box 100 to the transfer box 110 on the transfer platform 2021 close to the storage bracket 201, which greatly liberates manpower and improves production efficiency. When the transfer box 110 at one end of the transfer platform 2021 is equipped with needles, the transfer platform 2021 rotates 180°. At this time, the empty transfer box 110 at the other end is close to the storage bracket 201, and the needle matching assembly 203 can continue to match the drill needles 120 of corresponding models and quantities. At the same time, the transfer mechanism 204 transfers the transfer box 110 on the transfer platform 2021 after the needle matching to the material tray 130 at the material receiving position. After that, the transfer mechanism 204 transfers the empty transfer box 110 at the temporary storage position to the vacant storage area 2022 on the transfer platform 2021. This cycle is repeated to achieve rapid replacement of the transfer box 110, so that the needle matching device 20 is always in working condition, thereby improving production efficiency.

As shown in FIG5 , the needle matching assembly 203 further includes a first slide rail 2032, a second slide rail 2033 and a first sliding member 2034. The first slide rail 2032 extends along the X-axis direction, the second slide rail 2033 is slidably disposed on the first slide rail 2032 along the X-axis direction, the first sliding member 2034 is slidably disposed on the second slide rail 2033 along the Y-axis direction, and the pick-and-place member 2031 is slidably disposed on the first sliding member 2034 along the Z-axis direction. The needle matching assembly 203 is a gantry structure, which enables the pick-and-place member 2031 to move in three directions to realize the pick-and-place of the drill needle 120 on the storage bracket 201, and the control is precise.

As shown in Figure 5, the transfer mechanism 204 includes a first slider 2041, a first lifting member 2042 and a clamping assembly 2043. The first slider 2041 is slidably set on the first slide rail 2032 and can move back and forth along the X-axis direction. The first lifting member 2042 is slidably set on the first slider 2041 along the Z-axis direction. The clamping assembly 2043 is set on the first lifting member 2042. The clamping assembly 2043 is configured to clamp the transfer box 110 at the temporary storage position and transfer it to the storage area 2022 of the transfer platform 2021 away from the storage bracket 201, and to clamp the transfer box 110 after needle assembly in the storage area 2022 of the transfer platform 2021 away from the storage bracket 201 and transfer it to the material tray 130 at the receiving position.

Preferably, as shown in FIG8 , the clamping assembly 2043 includes a second fixing member 20431, a second clamping member 20432 and an abutting member 20433. The second clamping member 20432 is disposed on the second fixing member 20431. The abutting member 20433 is disposed on the first lifting member 2042 and spaced apart from the second clamping member 20432. The second fixing member 20431 is slidably disposed on the first lifting member 2042. As the second fixing member 20431 moves relative to the first lifting member 2042, the second clamping member 20432 can push the transfer box 110 in the storage slot 2023, so that the transfer box 110 abuts against the abutting member 20433, and is thus clamped by the clamping assembly 2043.

Furthermore, the clamping assembly 2043 further includes a third elastic member 20434. The second clamping member 20432 is slidably disposed on the second fixing member 20431. The third elastic member 20434 is disposed between the second clamping member 20432 and the second fixing member 20431. The third elastic member 20434 is configured to drive the second clamping member 20432 to approach the abutting member 20433. The third elastic member 20434 can apply an elastic force to the second clamping member 20432 when the second clamping member 20432 abuts against the transfer box 110, so that the clamping force of the second clamping member 20432 and the abutting member 20433 on the transfer box 110 gradually increases, thereby preventing the transfer box 110 from being damaged by clamping.

As shown in Fig. 7, Fig. 9 and Fig. 10, the transfer mechanism 202 includes a clamping assembly 2024, and each storage slot 2023 is correspondingly provided with a clamping assembly 2024, and the clamping assembly 2024 is configured to abut the transfer box 110 in the storage slot 2023 against the positioning side wall of the storage slot 2023. The clamping assembly 2024 is used to push the transfer box 110 in the storage slot 2023 so that the transfer box 110 abuts against the positioning side wall of the storage slot 2023, thereby ensuring that the positioning reference of the transfer box 110 in the storage slot 2023 is the same, and improving the accuracy of the transfer mechanism 204 clamping the transfer box 110 in the storage slot 2023.

Specifically, the clamping assembly 2024 includes a first fixing member 20241 and a first clamping member 20242 disposed on the first fixing member 20241. The first fixing member 20241 is slidably disposed on the transfer platform 2021, and the first clamping member 20242 is at least partially disposed in the storage slot 2023. As the first fixing member 20241 moves relative to the transfer platform 2021, the portion of the first clamping member 20242 located in the storage slot 2023 can push the transfer box 110 in the storage slot 2023, so that the transfer box 110 abuts against the positioning side wall.

The clamping assembly 2024 further includes a clamping drive (not shown), which drives the first fixing member 20241 to move, so as to drive the first clamping member 20242 to abut the transfer box 110 in the storage slot 2023 against the positioning side wall of the storage slot 2023. In this embodiment, the clamping drive is a cylinder, and the first fixing member 20241 is connected to the piston rod of the cylinder. In other embodiments, the clamping drive can also be a linear motor, a screw nut structure, etc.

Furthermore, the clamping direction of the first clamping member 20242 of the storage area 2022 away from the storage bracket 201 is opposite to the clamping direction of the second clamping member 20432 of the clamping assembly 2043. When the clamping assembly 2043 needs to clamp the transfer box 110, the clamping drive member has returned, and the first clamping member 20242 has also released the transfer box 110. At this time, the second clamping member 20432 can push the transfer box 110 in the storage slot 2023, so that the transfer box 110 abuts against the abutting member 20433 of the clamping assembly 2043 and is clamped and fixed.

In order to avoid unnecessary losses caused by the second clamping member 20432 pushing the transfer box 110 in the opposite direction to the driving force of the clamping driver, the clamping driver pushes the first fixing member 20241 close to the positioning side wall. The clamping driver and the first fixing member 20241 are not fixedly connected, but the clamping driver can push the first fixing member 20241 to move, which makes the clamping driver only able to drive the first fixing member 20241 to move in a single direction. In other words, the clamping driver can return after driving the first fixing member 20241 to position the transfer box 110, and at this time, the clamping driver is disengaged from the first fixing member 20241.

Furthermore, the clamping assembly 2024 also includes a second elastic member 20244, which is disposed between the first fixing member 20241 and the transfer platform 2021, and is configured to drive the first fixing member 20241 away from the positioning side wall. Specifically, a fixing block 2025 is fixedly disposed on the transfer platform 2021, and the second elastic member 20244 abuts against the fixing block 2025. Since the clamping drive member can only drive the first fixing member 20241 to move in one direction, the second elastic member 20244 is required to drive the first fixing member 20241 to return, so as to increase the distance between the first clamping member 20242 and the positioning side wall, so as to facilitate the placement of the transfer box 110.

As shown in Fig. 9 and Fig. 10, in this embodiment, the clamping assembly 2024 further includes a first elastic member 20243, the first clamping member 20242 is slidably disposed on the first fixing member 20241, the first elastic member 20243 is disposed between the first clamping member 20242 and the first fixing member 20241, and the first elastic member 20243 is configured to drive the first clamping member 20242 to approach the positioning side wall. The first elastic member 20243 can apply an elastic force to the first clamping member 20242 when the first clamping member 20242 abuts against the transfer box 110, so that the clamping force of the first clamping member 20242 and the positioning side wall on the transfer box 110 gradually increases, thereby preventing the transfer box 110 from being damaged by clamping.

In this embodiment, as shown in Fig. 7, each storage area 2022 is provided with two clamping assemblies 2024, and the clamping directions of the two clamping assemblies 2024 are arranged at an angle. The two clamping assemblies 2024 can position the transfer box 110 from two different directions, further improving the consistency of the position of the transfer box 110.

In this embodiment, each storage area 2022 of the transfer platform 2021 includes a plurality of storage slots 2023, and the plurality of storage slots 2023 are arranged at intervals along the Y-axis direction. The plurality of storage slots 2023 can store a plurality of transfer boxes 110 at the same time, that is, the needle matching device 20 can match needles to a plurality of transfer boxes 110 at the same time, which greatly improves the efficiency of the needle matching device 20.

Correspondingly, the clamping assembly 2024 also includes a plurality of first clamping members 20242 , which are all fixedly disposed on the first fixing member 20241 . The first fixing member 20241 can move so that the plurality of first clamping members 20242 can simultaneously abut the plurality of transfer boxes 110 against the positioning side walls of the corresponding storage slots 2023 .

In order to facilitate the arrangement of the clamping assembly 2024 in different directions, the present embodiment provides two structures of the clamping assembly 2024. The clamping assembly 2024 in FIG. 9 is a structure for clamping the transfer box 110 along the X-axis direction, and the clamping assembly 2024 in FIG. 10 is a structure for clamping the transfer box 110 along the Y-axis direction. These two clamping assemblies 2024 can be arranged under the transfer platform 2021 at the same time, and the two do not interfere with each other and can work at the same time.

Similarly, the clamping assembly 2043 also includes a plurality of second clamping members 20432 and abutting members 20433. The plurality of second clamping members 20432 are fixedly disposed on the second fixing member 20431. The second fixing member 20431 can move so that the plurality of second clamping members 20432 can clamp a plurality of transfer boxes 110 at the same time, thereby improving efficiency.

It is worth noting that the arrangement of the first elastic member 20243 and the third elastic member 20434 can offset the size difference when the first clamping member 20242 and the second clamping member 20432 clamp the transfer boxes 110 of similar sizes, thereby ensuring the stability of the positioning and clamping movement of the transfer box 110.

It is understandable that the number of material boxes 100 stored on the storage bracket 201 is limited. When the models of the drill bits 120 in the material boxes 100 stored on the storage bracket 201 do not meet the requirements, it is necessary to replace some of the material boxes 100 stored on the storage bracket 201, that is, to replace the models of the drill bits 120.

To achieve the above purpose, as shown in FIG5 , the needle dispensing device 20 further includes an exchange component 205 and a buffer bracket 206. The buffer bracket 206 is provided with a plurality of buffer slots 2061, and the buffer slots 2061 are used to place the material storage box 100. The exchange component 205 is configured to transfer the material storage box 100 on the storage bracket 201 to the buffer slots 2061 of the buffer bracket 206, and move the material storage box 100 in other buffer slots 2061 to the storage bracket 201. The exchange component 205 specifically includes a third slide rail 2051, a second sliding member 2052, and an exchange clamping member 2053. The third slide rail 2051 moves along the X-axis direction, the second sliding member 2052 is slidably disposed on the third slide rail 2051 along the Y-axis direction, and the exchange clamping member 2053 is slidably disposed on the second sliding member 2052 along the Z-axis direction.

Furthermore, as shown in Figure 1, the needle dispensing device 20 also includes an empty material box flow channel 207, which is sloped and located between the storage bracket 201 and the cache bracket 206. The exchange component 205 is also configured to transfer the empty material box 100 on the storage bracket 201 to the empty material box flow channel 207 to recycle the empty material box 100.

When in use, the exchange clamp 2053 can clamp the unnecessary storage box 100 on the storage bracket 201 and move it to the buffer slot 2061 of the buffer bracket 206, and move the storage box 100 of the model that meets the requirements in other buffer slots 2061 to the storage bracket 201 for use by the needle matching assembly 203. As for the empty storage box 100 on the storage bracket 201, the exchange clamp 2053 clamps it in the empty box flow channel 207. A recycling frame is provided below the empty box flow channel 207. The empty storage box 100 flows into the recycling frame through the empty box flow channel 207 for subsequent use in recycling the drill needle 120. No shutdown is required in this process, which improves production efficiency.

It is understandable that the third slide rail 2051 can also be slidably disposed on the first slide rail 2032 to simplify the structure of the needle matching device 20. In this embodiment, the first slide rail 2032 is a three-moving linear motor, and the second slide rail 2033, the third slide rail 2051 and the first slider 2041 are respectively fixedly connected to a moving element to independently drive the second slide rail 2033, the third slide rail 2051 and the first slider 2041 to move along the X-axis direction.

At the same time, the clamping component 305 clamps the storage box 100 with a model that meets the requirements in the three-dimensional warehouse 301 and moves it to other cache slots 2061 of the cache bracket 206, and moves the unnecessary storage box 100 in the cache slot 2061 to the corresponding storage position 3014 in the three-dimensional warehouse 301. At the same time, the exchange clamping component 2053 moves the storage box 100 with a model that meets the requirements in the cache slot 2061 to the storage bracket 201 for use by the needle matching component 203, thereby completing the replacement of the storage box 100.
