The following description sets forth many specific details to facilitate a full understanding of the present application. However, the present application can be implemented in many other ways than those described herein, and those skilled in the art can make similar improvements without violating the scope of the present application. Therefore, the present application is not limited to the specific embodiments disclosed below.

The materials in this embodiment include but are not limited to reaction containers, such as reaction cups, reaction tubes, etc. The following description will specifically use the reaction container as a reaction cup as an example, but the invention is not limited thereto.

1 and 2 , FIG1 shows a structural diagram of a buffer mechanism 10 and a conveying rack 20 according to an embodiment of the present application.

Figure 2 shows a structural diagram of the structure shown in Figure 1 in a loading state. An embodiment of the present application provides a cache mechanism 10 for receiving materials 30 output by a conveyor rack 20. The cache mechanism 10 includes: a rotating disk 11 and a first driving mechanism 12. The outer periphery of the rotating disk 11 is provided with a first groove 111 and a material beating portion 112. The first groove 111 is used to receive and accommodate the material 30 output by the conveyor rack 20. The material beating portion 112 can contact the material 30 output by the conveyor rack 20 when the rotating disk 11 rotates and can push the material 30 back to the conveyor rack 20. The first driving mechanism 12 is connected to the rotating disk 11, and the first driving mechanism 12 is used to drive the rotating disk 11 to rotate.

The above-mentioned buffer mechanism 10 has a material beating portion 112 on the outer periphery of the rotating disk 11. The material portion 112 acts on the material 30 on the conveyor rack 20, causing the material 30 to shake back and forth on the slide 21 of the conveyor rack 20. The direction of the back-and-forth movement is indicated by the double arrow f in Figures 1 and 2, thereby adjusting the posture of the material 30 on the conveyor rack 20, enabling the material 30 on the slide 21 to be neatly arranged, and even enabling the material 30 lying flat on the slide 21 to be straightened or dropped out of the slide 21. When the first groove 111 rotates to a position corresponding to the discharge port 211 of the slide 21 of the conveyor rack 20, the material 30 slides along the slide 21 under the action of its own gravity and smoothly enters the first groove 111 and is accommodated inside the first groove 111 to complete the caching of the material 30. The neatly arranged material 30 entering the first groove 111 can greatly reduce material jamming problems, thereby improving work efficiency.

In some embodiments, the number of times the material 30 is aligned by the material beating portion 112 is controlled by controlling the number of revolutions of the rotating disk 11. Specifically, the rotating disk 11 rotates not just once, but multiple times to align the material 30. A greater number of times the material 30 is aligned increases the amount of force applied to the material 30 within the chute 21, thereby facilitating alignment of the material 30 within the chute 21.

In some embodiments, the first driving mechanism 12 includes various power structures such as a driving motor and a rotary cylinder that can drive the rotating disk 11 to rotate.

In some embodiments, the material removal portion 112 includes a second groove, wherein the groove depth S2 of the second groove is less than the groove depth S1 of the first groove 111. The outer diameter D of the material 30 is less than the groove depth S1 of the first groove 111, so that when entering the first groove 111, it can be completely accommodated within the first groove 111. In addition, the outer diameter D of the material 30 is, for example, greater than 0.8S1, so that each first groove 111 can be filled with a material 30. During the rotation of the rotating disk 11, the material 30 at the discharge port 211 of the slideway 21 can be individually separated.

In addition, the outer diameter D of the material 30 is greater than the groove depth S2 of the second groove, so that when it enters the second groove, it can be pushed back into the slide 21 by the bottom wall of the second groove, that is, the material 30 in the slide 21 is straightened, so that the material 30 in the slide 21 is neatly arranged.

In this embodiment, 0.1D≦S2<0.5D. Thus, on the one hand, the groove depth S2 of the second groove is large enough to allow the material 30 on the slide 21 to have a larger movement stroke into the second groove, which is beneficial to the straightening effect of the material 30 in the slide 21; on the other hand, the groove depth S2 of the second groove is not too large, so as to avoid the groove depth of the second groove being too large, which causes the material 30 to enter the second groove and be unable to return to the slide 21 from the second groove, that is, to prevent the material 30 from being stuck in the second groove.

Please refer to Figures 1 and 2. In some embodiments, the groove wall of the first groove 111 is adapted to the outer wall shape of the material 30, which can stably accommodate the material 30 and reduce collision noise. In addition, the groove wall of the second groove is, for example, set to an arc shape, specifically adapted to the outer wall shape of the material 30, which can reduce collision noise and wear, and can be used to prevent the material from being chopped during the punching process. The material 30 is smoothly returned to the slideway 21 .

In some embodiments, the material beating part 112 is not limited to the second groove in the above-mentioned embodiment, but can also be set as an elastic part, for example. When the rotating disk 11 drives the elastic part to rotate to the position corresponding to the slide 21, the material 30 will move toward the elastic part to compress the elastic part. The elastic part can also push the material 30 back into the slide 21, thereby realizing the up and down shaking action of the material 30 on the slide 21, which can also play the role of sorting the material 30; it can also be set as a retractable structure, for example, the retractable structure pushes the material 30 and sorts the material 30 through its own retractable movement, and specifically, it can be set as various power mechanisms such as a telescopic cylinder.

Referring to Figures 1 and 2 , in some embodiments, multiple first grooves 111 are provided and spaced apart around the circumference of the rotating disk 11. This allows the rotating disk 11 to simultaneously accommodate multiple materials 30. With each rotation of the rotating disk 11, multiple first grooves 111 serve as receiving locations for the materials 30 discharged from the chute 21, thereby improving loading efficiency. Alternatively, a single first groove 111 may be provided.

1 and 2 , in some embodiments, all first grooves 111 are evenly spaced around the outer circumference of the rotating disk 11. Specifically, when there are eight first grooves 111, that is, every 45° rotation of the rotating disk 11 controls one of the first grooves 111 to rotate to a position corresponding to and communicating with the slideway 21.

Referring to Figures 1 and 2 , in some embodiments, multiple second grooves are provided and spaced apart around the circumference of the rotating disk 11. Thus, with each rotation of the rotating disk 11, multiple second grooves function as the material-beating portions 112 to act on the chute 21, thereby achieving multiple straightening of the material 30 within the chute 21, ensuring that the material 30 within the chute 21 is neatly arranged and reducing material jamming. Alternatively, a single second groove may be provided.

Referring to Figures 1 and 2 , in some embodiments, all second grooves are evenly spaced around the outer circumference of the rotating disk 11. Specifically, when there are eight second grooves, that is, every 45° rotation of the rotating disk 11 controls one of the second grooves to rotate to a position corresponding to the chute 21, thereby knocking out the material 30 within the chute 21.

1 and 2 , in some embodiments, the first grooves 111 and the second grooves are arranged alternately. Of course, the first grooves 111 and the second grooves can also be flexibly arranged on the periphery of the rotating disk 11 in other ways, which are not limited here.

Please refer to Figures 1 and 2. In one embodiment, the cache mechanism 10 further includes a fixed seat 13. The fixed seat 13 is provided with a receiving cavity 131. The rotating disk 11 is rotatably disposed in the receiving cavity 131. The fixed seat 13 is further provided with a docking port 132 corresponding to the receiving cavity 131. The docking port 132 is used to communicate with the discharge port 211 of the slide 21 of the conveying rack 20. In this way, when the rotating disk 11 drives the first groove 111 to rotate to a position corresponding to the docking port 132, the slide 21 is connected to the first groove 111 through the docking port 132, so that the material 30 can enter the first groove 111 through the docking port 132; when the rotating disk 11 drives the punching When the part 112 rotates to a position corresponding to the docking port 132 , the material beating part 112 can act on the material 30 in the slide 21 through the docking port 132 , so that the material 30 moves up and down in the slide 21 to achieve a sorting effect.

Referring to Figures 1 and 2 , specifically, the outer periphery of the rotating disk 11 and the inner wall of the accommodating chamber 131 are loosely fitted, or are in slidable contact with each other. This effectively prevents material 30 entering the second groove through the docking port 132 from entering the next workstation as the rotating disk 11 rotates. Instead, the material 30 is propelled outward by the rotating disk 11 and pushed back into the chute 21, ensuring the correct impact of the material 30 within the chute 21. Furthermore, the inner wall of the accommodating chamber 131 cooperates with the first groove 111 to stably store the material 30 within the rotating disk 11, preventing the material 30 from being thrown outward by the centrifugal force generated during the rotation of the rotating disk 11.

In some embodiments, the cache mechanism 10 is further provided with a material unloading station, for example. The material unloading station can be set at any position around the fixed seat 13 according to actual needs, as long as it is convenient to transfer the material 30 at the material unloading station to other stations. Specifically, when the rotating disk 11 drives the material 30 to rotate to the material unloading station, a method including but not limited to a manipulator is used to grab the material 30 at the material unloading station and transfer it to other stations, or a conveyor belt is used to transfer the material 30 at the material unloading station to other stations. Optionally, in order to facilitate the outward transfer of the material 30 at the material unloading station, a material unloading port is provided on the side wall of the fixed seat 13, for example. A pushing mechanism can be used to convey the material 30 at the material unloading station through the material unloading port to the conveyor belt, and then transfer it outward through the conveyor belt.

Referring to Figures 1 and 2 , in one embodiment, the buffer mechanism 10 further includes a first sensing component 14. The first sensing component 14 is mounted on the fixing base 13 and is configured to sense the presence of material 30 within the first recesses 111. The first sensing component 14 is electrically connected to the first driving mechanism 12. Specifically, as the rotating disk 11 rotates, each first recess 111 rotates sequentially to a position corresponding to the first sensing component 14. The first sensing component 14, through, for example, photoelectric sensing, sequentially senses the presence of material 30 within the corresponding first recess 111. Among them, when the first sensing component 14 senses that there is no material 30 in the first groove 111, the first driving mechanism 12 drives the rotating disk 11 to rotate accordingly, and rotates the first groove 111 without material 30 to a position corresponding to the discharge port 211 of the slide 21, and loads the material 30 on the slide 21 into the first groove 111, so that the loading operation can be performed accurately and the loading efficiency can be improved; when the first sensing component 14 senses that there is material 30 in the first groove 111, the material 30 inside the first groove 111 can be unloaded at the unloading station.

Optionally, the first sensing component 14 includes but is not limited to a photoelectric switch, a magnetic induction switch, etc. The photoelectric switch can be a sensor with stable and reliable performance such as an infrared photoelectric sensor, a light sensitive sensor, etc.

Please refer to Figures 1 and 2. In one embodiment, a loading device includes the buffer mechanism 10 of any of the above embodiments and also includes a conveyor frame 20. The conveyor frame 20 is provided with an inclined slide 21, and the discharge port 211 of the slide 21 is When the rotating disk 11 drives the first groove 111 to face the discharge port 211, the material 30 in the slide 21 can slide into the first groove 111 through the discharge port 211; when the rotating disk 11 drives the material-beating portion 112 to face the discharge port 211, the material-beating portion 112 can push the material 30 in the slide 21.

In the above-mentioned loading device, since the outer periphery of the rotating disk 11 is provided with a material beating portion 112, when the rotating disk 11 rotates, the material beating portion 112 acts on the material 30 on the conveyor rack 20, causing the material 30 to shake back and forth on the slide 21 of the conveyor rack 20, thereby adjusting the posture of the material 30 on the conveyor rack 20, and can make the material 30 on the slide 21 neatly arranged, and even can straighten the material 30 lying flat on the slide 21 or drop it outside the slide 21. Then, when the first groove 111 rotates to a position corresponding to the discharge port 211 of the slide 21 of the conveyor rack 20, the material 30 slides along the slide 21 under the action of its own gravity and smoothly enters the first groove 111 and is accommodated inside the first groove 111 to complete the caching of the material 30. The neatly arranged material 30 entering the first groove 111 can greatly reduce material jamming problems, thereby improving work efficiency.

Referring to Figures 1 and 2 , in some embodiments, the width of the slideway 21 is W. The width W of the slideway 21 is adjusted and set according to the outer diameter D of the material 30, as long as the material 30 can stably run along the slideway 21. Specifically, W includes but is not limited to D to 1.2D, such as D, 1.1D, 1.2D, etc.

Referring to Figures 1 and 2 , in this embodiment, the conveyor frame 20 includes two spaced-apart track plates 22. The two track plates 22 cooperate to form a slideway 21. The spacing between the two track plates 22 is also the width W of the slideway 21. The track plates 22 can be straight, curved, or other irregularly shaped.

Please refer to Figures 3 and 4. In one embodiment, the cache mechanism 10 also includes a limit frame 40. The limit frame 40 is installed on the conveying frame 20. The limit frame 40 includes a limit plate 41 arranged at intervals on the top of the conveying frame 20 and/or a stop portion 42 located above the rotating disk 11 and spaced relative to the discharge port 211 of the slide 21. In this way, the limit plates 41 are arranged at intervals above the conveying frame 20 to guide and limit the various materials 30 in the slide 21, which is conducive to the smooth sliding of the materials 30 inside the slide 21 into the first groove 111. When the material 30 slides down the slide 21 into the first groove 111, the stop portion 42 stops the material 30 rushing into the first groove 111, preventing the material 30 from rushing out of the first groove 111, thereby improving the stability of the material 30 inside the first groove 111.

In some embodiments, the blocking portion 42 is connected and fixed to the limiting plate 41 , including but not limited to being integrally formed.

Please refer to Figures 3 and 4. In one embodiment, the limiting frame 40 further includes a side panel 43 connected to one side of the conveying frame 20. The side panel 43 is connected to the limiting plate 41, and the distance between the side of the limiting plate 41 away from the side panel 43 and the top of the conveying frame 20 is greater than the outer diameter D of the material 30. In this way, on the one hand, the side panel 43 located on one side of the conveying frame 20 together with the limiting plate 41 can limit and guide the material 30 in the slide 21, so that the material 30 can slide smoothly from the slide 21 to the rotating disk 11; on the other hand, due to the distance between the side of the limiting plate 41 away from the side of the side panel 43 and the top of the conveying frame 20, the material 30 can slide smoothly from the slide 21 to the rotating disk 11. The spacing is greater than the outer diameter D of the material 30, that is, when there is material 30 lying flat on the slide 21 (as shown in Figure 2), the material 30 lying flat can slide out through the opening 45 formed by the limiting plate 41 and the conveying frame 20 under the push of the material beating part 112 without being hit straight, thereby preventing the material 30 from getting stuck.

Referring to Figure 4 , in some embodiments, the side panels 43 include, but are not limited to, being rotatably connected to the conveyor frame 20. In this embodiment, the side panels 43 are rotatably connected to the conveyor frame 20 using, for example, hinges 44. This allows the side panels 43 to be opened and handled as needed when a material jam occurs within the slideway 21.

Referring to FIG5 , in one embodiment, the loading device further includes a hopper mechanism 50 and a pushing mechanism 60. The hopper mechanism 50 is used to store the material 30 and is connected to the conveyor frame 20. The pushing mechanism 60 is also connected to the hopper mechanism 50. The pushing mechanism 60 is used to push the material 30 within the hopper mechanism 50 to the inlet 212 of the chute 21 of the conveyor frame 20, so that the material 30 enters the chute 21 through the inlet 212. Thus, the pushing mechanism 60, through repeated lifting and lowering motions, can push the disordered material 30 within the hopper mechanism 50 to the inlet 212, from which the material 30 enters the chute 21, thereby being buffered by the chute 21. Once inside the chute 21, the material 30 moves along the chute 21 under its own weight and is neatly arranged along the chute 21, forming an ordered state of the material 30. This allows the material 30 to be smoothly loaded onto the rotating disk 11, thereby significantly reducing material jamming.

Among them, the number of materials 30 that the silo component in this embodiment can accommodate is adjusted and set according to actual needs, including but not limited to 100, 200, 500, 1000 or even more.

In one embodiment, the loading device further includes a controller and a second sensing component. The controller is electrically connected to the second sensing component and the pushing mechanism 60, respectively. The second sensing component is disposed on the conveyor frame 20 and is used to detect whether there is material 30 in the chute 21. When the second sensing component senses that there is no material 30 in the chute 21, the controller controls the pushing mechanism 60 to perform a pushing action. Thus, when the second sensing component senses that there is no material 30 in the chute 21, the controller controls the pushing mechanism 60 to repeatedly lift and lower, performing a pushing action. The pushing mechanism 60 can then push the material 30 inside the hopper mechanism 50 upward, allowing the material 30 to enter the chute 21 through the feed port 212. After the second sensing component senses the material 30, the controller controls the pushing mechanism 60 to stop.

In a specific embodiment, the loading device comprises the following steps:

Step S100: pouring the material 30 into the silo mechanism 50;

In step S200, the pushing mechanism 60 repeatedly lifts and lowers to push the material 30 inside the hopper mechanism 50 upward, so that the material 30 enters the chute 21 through the inlet 212. The material 30 moves along the inclined chute 21 under the action of its own gravity and can be neatly arranged in the chute 21.

Step S300: The rotating disk 11 rotates to separate the materials 30 on the slide 21 individually and wait for the gripper to pick up the materials.

Specifically, when the rotating disk 11 drives the first groove 111 to rotate to a position corresponding to the docking port 132, the slide 21 is connected to the first groove 111 through the docking port 132, so that the material 30 can enter the first groove 111 through the docking port 132; when the rotating disk 11 drives the material beating part 112 to rotate to a position corresponding to the docking port 132, the material beating part 112 can act on the material 30 in the slide 21 through the docking port 132, so that the material 30 moves up and down in the slide 21 to achieve a sorting effect.

Please refer to FIG. 1 and FIG. 2 . In one embodiment, a sample analyzer is provided. The sample analyzer includes the loading device according to any one of the above embodiments.

In the above-mentioned sample analyzer, since the outer periphery of the rotating disk 11 is provided with a material beating portion 112, when the rotating disk 11 rotates, the material beating portion 112 acts on the material 30 on the conveyor rack 20, causing the material 30 to shake back and forth on the slide 21 of the conveyor rack 20, thereby adjusting the posture of the material 30 on the conveyor rack 20, and can make the material 30 on the slide 21 neatly arranged, and even can straighten the material 30 lying flat on the slide 21 or drop it outside the slide 21. Then, when the first groove 111 rotates to a position corresponding to the discharge port 211 of the slide 21 of the conveyor rack 20, the material 30 slides along the slide 21 under the action of its own gravity and smoothly enters the first groove 111 and is accommodated inside the first groove 111 to complete the caching of the material 30. The neatly arranged material 30 entering the first groove 111 can greatly reduce material jamming problems, thereby improving work efficiency.
