The invention provides a display panel adsorption device.

Referring to FIGS. 1 to 5 , in one embodiment of the present invention, the display panel adsorption device includes a support platform 100 with a plurality of support members 200 on the surface. The end of the support member 200 is provided with a suction cup 210 for adsorbing the display panel. , the height of the suction cup 210 relative to the support platform 100 can be adjusted.

Specifically, the display panel is placed on the support platform 100 of the display panel adsorption device, and the suction cups 210 of the multiple supports 200 are adsorbed to multiple different planar action points of the display panel, so that the display panel can be stably placed on the display panel. Support platform 100; In addition, the suction cup 210 of any support member 200 can be adjusted in height to change the distance between the suction cup 210 and the support platform 100. When the height of the suction cup 210 of a certain support member 200 is in contact with other suction cups 210 When the height planes are different, the suction cup 210 of the support member 200 can be adjusted so that the suction cup 210 reaches the height plane where other suction cups 210 are located. In addition, due to the surface flatness of the display panel

In the technical solution of the present invention, the support platform 100 is provided with a plurality of support members 200 for adsorbing the display panel. In this way, the support platform 100 is provided with a plurality of action points for adsorbing and supporting the display panel, thereby improving the display quality. The adsorption and support effect of the panel adsorption device on the display panel; in addition, the height of the suction cup 210 of the support 200 for adsorbing the display panel is adjustable. Before placing the display panel on the adsorption device, the user can adjust the suction cup of the support 200 210 height, so that the suction cups 210 of multiple supports 200 can form a horizontal adsorption surface, or the suction cups 210 of one or more supports 200 can be adjusted in a targeted manner during the operation of the adsorption device, so that the display panel can be When adsorbed on the adsorption device, the display panel can be horizontal.

In addition, since the accuracy of the surface flatness of the display panel is very high, the deformation caused by the weight of the support platform 100 will also affect the flatness of the display panel surface. Therefore, the user can move the support member 200 in the middle of the support platform 100 The height of the suction cup 210 is increased to enlarge the distance between the part of the suction cup 210 and the part of the support platform 100, thereby compensating for the deformation of the support platform 100 due to its own weight.

It is worth mentioning that the display panel adsorption device can also achieve adsorption of the arc-shaped display panel 10 by adjusting each support member 200 .

Please refer to FIG. 3 . In one embodiment, the support member 200 includes a support body 230 , a suction cup 210 movably connected to the support body 230 , and an adjusting lever disposed between the support body 230 and the suction cup 210 . The height knob 220 can adjust the height of the suction cup 210 relative to the support platform 100 by turning the height adjustment knob 220. In this way, the user can adjust the height of each suction cup 210 relative to the support platform 100 according to the actual position of the suction cup 210. The height enables each suction cup 210 to form a horizontal support plane, so that the display panel can be evenly adsorbed to the surface of the support platform 100 . In other embodiments, the support platform 100 is provided with a support plate, and the support plate is provided with a plurality of air holes for adsorbing the display panel.

Further, a locking knob 240 is provided between the height adjustment knob 220 and the support body 230. Specifically, please refer to FIG. 3. By rotating the locking knob 240, the suction cup 210 can be locked relative to the position of the suction cup 210. The height of the support platform 100 is described above. In this way, after the suction cup 210 adsorbs the display panel, the suction cup 210 will not move close to the support platform 100 due to the mass of the display panel, so that the height of the suction cup 210 relative to the support platform 100 can be maintained, further ensuring This improves the flatness of the display panel in the adsorbed state. It is worth mentioning that due to the different distances between the various parts of the display panel and the geometric center of the panel, the deformation capabilities of various parts of the display panel due to gravity are different. When the periphery of the panel is supported by the support member 200, the panel There is a concave tendency due to the effect of gravity. The degree of concavity of each part of the panel decreases from the geometric center of the panel to the periphery of the panel. Therefore, the support member 200 corresponding to the middle part of the display panel is smaller than the support member 200 corresponding to the middle part of the display panel. For the support 200 at the edge of the display panel, the support 200 corresponding to the middle of the display panel provides greater support for the display panel. When the locking knob 240 locks the suction cup 210, the suction cup 210 is positioned relative to the support platform 100. When the height is fixed, the suction cup 210 can more stably support the display panel it is adsorbed. In this way, when the locking knob 240 locks the suction cup 210, the support capacity of the support member 200 for the display panel is increased to a certain extent, thereby improving the display quality. Support effect of panel adsorption device.

Please refer to Figure 2. In one embodiment, the display panel adsorption device further includes a base 400 and a driving member 300. The driving member 300 is located between the base 400 and the support platform 100 and is used to drive The support platform 100 lifts, lowers and rotates. Specifically, after the display panel is adsorbed on the support platform 100, the display panel needs to be transported so that the display panel can enter the next operation step. In this way, the driving member 300 can drive the movement of the support panel to drive the display panel to move, thereby making the display panel move. The display panel enters the next operation stage.

In other embodiments, the suction cup 210 is configured with anti-static material. During the workshop production process, it is necessary to maintain good static elimination functions between operating equipment, equipment and products to avoid accumulation of charges or adsorption of dust, and to reduce the occurrence of physical and chemical damage to the display panel caused by static electricity. Since the suction cup 210 is the main component that frequently contacts the display panel in this technical solution, the suction cup 210 is made of anti-static material to avoid accumulation of charge on the surface of the suction cup 210 and thereby improve the insulation of the display panel adsorption device.

In another embodiment, the surface of the suction cup 210 is coated with an anti-static coating. This prevents charge accumulation on the surface of the suction cup 210 and improves the insulation of the display panel adsorption device.

In one embodiment, the driving member 300 is configured as a DC motor. DC motors are highly efficient, can accurately control factors such as direction and distance of movement, and have the characteristics of reversibility and high power density. Configuring the driving component 300 as a DC motor can improve the movement efficiency of the support platform 100 of the display panel adsorption device, making it possible to The support platform 100 can move the support platform 100 to a designated position more accurately. In other embodiments, the driving member 300 is configured as an AC motor.

In addition, the suction cup 210 is provided with an air hole 211, and the support body 230 is provided with a through hole 231 connected with the air hole 211; the display panel adsorption device also includes an air extraction device, and the air pipe of the air extraction device 10. The air hole 211 is connected through the through hole 231. In this way, when the air extraction device is turned on, the air holes 211 of the suction cup 210 can form a suction force, so that the display panel is adsorbed to the suction cup 210.

Furthermore, the surface of the suction cup 210 is provided with a guide groove 212 connected with the air hole 211. When suction is formed at the air hole 211, a corresponding suction force will be formed in the guide groove 212. In this way, when the display panel is adsorbed to the suction cup 210, the display panel The suction effect area between the suction cup 210 and the suction cup 210 is enlarged, which reduces the deformation of the display panel due to local stress and increases the suction effect of the suction cup 210 on the display panel. In other embodiments, the surface of the suction cup 210 is provided with anti-slip texture to prevent the display panel from shifting relative to the suction cup 210 .

In one embodiment, the plurality of supports 200 form a plurality of adsorption operation areas, and different adsorption operation areas are correspondingly connected to different air extraction devices or connected to different air extraction parts of the air extraction device, so that each The adsorption force of the adsorption work area is individually controllable.

It should be understood that when the size of the display panel is large and the periphery of the panel falls on the surface where the suction cup 210 is located without the support of the support member 200, the middle portion of the panel will tend to convex upward due to the gravity of the edge of the panel, where, The degree of convexity of each part of the board body decreases sequentially from the geometric center of the board body to the plane where the suction cup 210 is located. At this time, the support member 200 corresponding to the middle part of the display panel needs greater suction force to be able to adsorb the surface of the middle part of the display panel. on the surface of the suction cup 210;

When the size of the display panel is small, the edge of the display panel is supported by the support member 200. Since the distance between each part of the display panel and the geometric center of the panel is different, the deformation capabilities of each part of the display panel due to gravity are different. When When the periphery of the board body is supported by the support member 200, the board body tends to be concave due to the effect of gravity. The degree of concavity of each part of the board body decreases from the geometric center of the board body to the periphery of the board body, and the concave degree of the board body decreases in sequence. The edge may be tilted upward due to excessive concave deformation in the middle of the board. In this case, the edge of the board needs greater adsorption force;

In addition, when the size of the display panel is small and far from covering the entire surface of the support platform 100 (such as only occupying 30%, 50% of the surface of the support platform 100, etc.), at this time, most of the support members 200 do not contact the display panel;

To sum up, the support platform 100 is provided with multiple adsorption operation areas, so that the display panel can be better adsorbed to the suction cup 210 and also reduce the energy consumption of the display panel adsorption device.

Further, please refer to FIG. 4 , a plurality of the adsorption operation areas are arranged in an array on the support platform. In this way, the utilization rate of the support platform 100 is improved, and any surface of the support platform 100 can be formed to adsorb the display. The adsorption function of the panel enables the support platform 100 to adapt to display panels of various shapes and sizes, which expands the use range of the display panel adsorption device to a certain extent and improves the ease of use of the display panel adsorption device.

Specifically, in the embodiment of FIG. 4 , the surface of the support platform 100 is evenly divided into a first adsorption operation area 510 , a second adsorption operation area 520 , a third adsorption operation area 530 and a fourth adsorption operation area 540 . In this way, The user can open the adsorption operation area accordingly according to the actual placement of the board. Compared with the embodiment in which all supports 200 are switched to the adsorption state, the adsorption operation area is set in separate areas and only the adsorption operation area corresponding to the display panel is opened. The air extraction device can save energy consumption to a certain extent and improve the environmental protection functionality of the display panel adsorption device.

For example, when the size of the display panel is small and it is only placed correspondingly in the first adsorption operation area 510, it is only necessary to turn on the exhaust device of the first adsorption operation area 510. Similarly, the display panel can also be placed in the first adsorption operation area 510. Place it in the second adsorption operation area 520, the third adsorption operation area 530 or the fourth adsorption operation area 540; when the display panel is in a long strip shape and is placed in the first adsorption operation area 510 and the second adsorption operation area 520, At this time, just turn on the two air extraction devices corresponding to the first adsorption operation area 510 and the second adsorption operation area 520. It should be noted that, under normal circumstances, the display panel needs to be placed in one-to-one correspondence with the support platform 100 to cooperate with subsequent processing operations.

In other embodiments, please refer to FIG. 5 in detail. The plurality of adsorption operation areas include a central adsorption operation area 610 and an annular adsorption operation area. The annular adsorption operation area is arranged around the central adsorption operation area 610. In this way, when the middle part of the board body is tilted, or the edge of the board body is tilted, or the area of the board body is too small to cover the entire surface of the support platform 100, the adjustment can be made correspondingly according to the placement state between the board body and the support platform 100. The air extraction state of the air extraction device (such as opening and closing, air extraction intensity, etc.) enables the board to be better adsorbed to the support platform 100 .

Based on the above embodiments, there are multiple annular adsorption operation areas, and the plurality of annular adsorption operation areas are concentrically arranged and arranged one ring at a time on the surface of the support platform 100 . Please continue to refer to Figure 5. In detail, the surface of the support platform 100 is divided into a central adsorption operation area 610, a first annular adsorption operation area 620, a second annular adsorption operation area 630 and a third annular adsorption operation area 640. In this way, When the middle part of the board body is tilted, or the edge of the board body is tilted, or the area of the board body is too small to cover the entire surface of the support platform 100, the air extraction can be adjusted accordingly according to the placement state between the board body and the support platform 100. The pumping state of the device (such as opening and closing, pumping intensity, etc.) enables the board to be better adsorbed to the support platform 100 .

Specifically, when the size of the plate body is too large and there is no support member 200 at the edge, and its geometric center protrudes upward, at this time, the central adsorption operation area 610 (or other adsorption operation area) corresponding to the geometric center needs to provide a larger Suction force is used to adsorb the display panel to the plane where the suction cup 210 is located. In other adsorption operation areas, the suction force can be reduced accordingly or the air extraction device cannot be turned on; when the size of the board is small, supports 200 are correspondingly provided at the edges, but the edges When tilted upward, the third annular adsorption operation area 640 (or other adsorption operation area) corresponding to its edge needs to provide greater suction force to adsorb the display panel to the plane where the suction cup 210 is located, and other adsorption operation areas can correspond to Reduce the suction force or do not turn on the air extraction device; when the display panel area is too small, just turn on the adsorption working area corresponding to the display panel.

Please refer to Figure 1, Figure 4 and Figure 5. In other embodiments, the support platform 100 is also provided with a plurality of photographing parts 700 on the periphery. The photographing parts 700 are used to assist the user or the device operating system to determine the edge and support of the display panel. The relative position relationship between the platforms 100, specifically, corresponding marks can be made on the lower surface of the display panel. Through the pictures taken by the shooting unit 700, the user or the device operating system can determine the relative position of the display panel and the supporting platform 100. The user or device The operating system can determine whether the relative position of the display panel to the support platform 100 needs to be readjusted based on the data. It should be noted that when the imaging part 700 does not capture the mark, it proves that the plate corresponding to the imaging part 700 is placed on the surface of the support platform 100, and the relative position of the display panel and the support platform 100 can be comprehensively determined based on other imaging parts 700.
