[0017] A detection method for a display module defect detection device includes the following steps:

[0018] S1: When performing defect detection on the display module, first place the display module to be detected between the first clamping plate and the second clamping plate, and then rotate the rotating block. The rotation of the rotating block drives the rotation of the second threaded rod, the rotation of the second threaded rod drives the movement of the connecting block, and the movement of the connecting block drives the downward movement of the second clamping plate, so that the second clamping plate cooperates with the first clamping plate to clamp the display module tightly;

[0019] S2: After the display modules on the tops of multiple moving seats are all installed, then control the first motor to start through the PLC. The start of the first motor drives the rotation of the first threaded rod, the rotation of the first threaded rod drives the movement of the moving seat, so that the moving seat carries the display module to be detected and moves below the industrial camera, and the industrial camera performs defect detection on the display module;

[0020] S3: When one side of the display module is detected, control the second motor to start through the PLC to drive the rotation of the rotating shaft. The rotation of the rotating shaft drives the rotation of the mounting plate, the rotation of the mounting plate drives the first clamping plate and the second clamping plate to clamp the display module and flip it 180 degrees to detect the other side of the display module. When the other side of the display module is detected, start the second motor again to make it flip back to the original position;

[0021] S4: Then control the first motor to start again through the PLC. Through the movement of the moving seat, the detected display module moves to the side away from the top plate. The movement of the moving seat drives the movement of the rack plate. When the end of the rack plate moves and contacts the limiting rod, it slides into the inside of the fixing plate under force. The movement of the rack plate drives the rotation of the gear, the rotation of the gear drives the connecting rod to move upward, and the movement of the connecting rod drives the movement of the second clamping plate, so that the second clamping plate moves to the side away from the first clamping plate to loosen the display module, and the staff takes it out. The display module that has not been detected moves below the top plate to continue the detection;

[0022] S5: Finally, repeat the above steps for continuous detection.

[0023] The beneficial effects of the present invention are as follows:

[0024] 1. Through the setting of the moving component, when performing defect detection on the display module, first place the display module to be detected on the top of the moving seat, and then control the first motor to start through the PLC. The start of the first motor drives the rotation of the first threaded rod, the rotation of the first threaded rod drives the movement of the moving seat, so that the moving seat carries the display module to be detected and moves below the industrial camera, and the industrial camera performs detection on the display module. Since there are multiple moving seats, multiple display modules can be continuously detected to improve the detection efficiency.

[0025] 2. The present invention sets a clamping assembly. When performing defect detection on the display module, the display module is placed between the first clamping plate and the second clamping plate, and then the rotating block is rotated. The rotation of the rotating block drives the rotation of the second threaded rod, and the rotation of the second threaded rod drives the movement of the connecting block. The movement of the connecting block drives the second clamping plate to move downward, so that the second clamping plate cooperates with the first clamping plate to clamp the display module, ensuring that the display module remains stable during the detection process, reducing image blur or dislocation caused by vibration or movement, and thus improving the accuracy of defect detection.

[0026] 3. The present invention adopts the setting of the rotating component. When the display module is subjected to defect detection, after one side of the display module is detected, the second motor is started by PLC control to rotate the rotating shaft. The rotation of the rotating shaft drives the mounting plate to rotate. The rotation of the mounting plate drives the first clamping plate and the second clamping plate to clamp the display module and flip it 180 degrees to monitor the other side of the display module, thereby improving the comprehensiveness of the detection.

Detailed implementation manners

[0036] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0037] As Figures 1 to 8 shown, in the embodiment of the present invention, a display module defect detection device includes a workbench 1. A side plate 2 is fixedly installed at the top end of the workbench 1. A top plate 3 is fixedly connected to the top end of the side plate 2. An industrial camera 4 is installed at the bottom end of the top plate 3. The industrial camera 4 is arranged above the workbench 1. A moving seat 5 is installed at the top end of the workbench 1 through a moving component. There are multiple moving seats 5.

[0038] Among them, the moving component includes a first motor 7 arranged inside the workbench 1. A first threaded rod 6 is installed at one end of the first motor 7. The first threaded rod 6 is embedded inside the moving seat 5. The moving seat 5 and the first threaded rod 6 are connected through internal and external thread cooperation. A clamping component is arranged at the top end of the moving seat 5.

[0039] When detecting the defects of the display module, first place the display module to be detected on the top end of the moving seat 5, and then control the first motor 7 to start through the PLC. The start of the first motor 7 drives the rotation of the first threaded rod 6. The rotation of the first threaded rod 6 drives the movement of the moving seat 5, so that the moving seat 5 carries the display module to be detected and moves below the industrial camera 4. The industrial camera 4 detects the display module. Since there are multiple moving seats 5, multiple display modules can be continuously detected to improve the detection efficiency.

[0040] Existing: CN211426240U discloses a liquid crystal display module defect detection device convenient for conveying. This patent discloses the workbench 1, side plate 2, top plate 3 and industrial camera 4 proposed in this application document. These technical means will not be elaborated one by one here.

[0041] As shown Figures 1 to 7 shown, the clamping assembly includes a support plate 8 fixedly installed at the top end of the moving seat 5. There are two support plates 8 symmetrically arranged. One side of the support plate 8 is installed with a mounting plate 9 through a rotating assembly. One side of the mounting plate 9 is fixedly installed with a first clamping plate 16. Above the first clamping plate 16 is provided a second clamping plate 18. At the top end of the second clamping plate 18 is provided a fixing plate 12. Between the second clamping plate 18 and the fixing plate 12 is provided a moving assembly. One side of the fixing plate 12 is fixedly connected with a connecting block 13. The connecting block 13 is slidably installed inside the mounting plate 9. Inside the connecting block 13 is threadedly connected with a second threaded rod 14. The top end of the second threaded rod 14 is fixedly installed with a rotating block 15.

[0042] When performing defect detection on the display module, place the display module between the first clamping plate 16 and the second clamping plate 18, and then rotate the rotating block 15. The rotation of the rotating block 15 drives the rotation of the second threaded rod 14. The rotation of the second threaded rod 14 drives the movement of the connecting block 13. The movement of the connecting block 13 drives the second clamping plate 18 to move downward, so that the second clamping plate 18 cooperates with the first clamping plate 16 to clamp the display module tightly, ensuring that the display module remains stable during the detection process, reducing image blurring or misalignment caused by vibration or movement, and thus improving the accuracy of defect detection.

[0043] As shown Figure 5 shown, buffer pads 17 are installed on the side walls of the first clamping plate 16 and the second clamping plate 18.

[0044] When clamping the display module, it can not only increase the friction between the clamping surface and the display module, improve the clamping stability, but also reduce the impact force and vibration generated during the clamping process, thereby protecting the display module from physical damage.

[0045] As shown Figure 6 shown, the rotating assembly includes a rotating shaft 10 fixedly installed on one side of the mounting plate 9. One end of the rotating shaft 10 away from the mounting plate 9 is installed with a second motor 11. The second motor 11 is installed inside the support plate 8.

[0046] When performing defect detection on the display module, when one side of the display module is detected, the PLC controls the second motor 11 to start and drive the rotating shaft 10 to rotate. The rotation of the rotating shaft 10 drives the mounting plate 9 to rotate. The rotation of the mounting plate 9 drives the first clamping plate 16 and the second clamping plate 18 to hold the display module and flip it 180 degrees to monitor the other side of the display module, improving the comprehensiveness of the detection.

[0047] As shown Figures 1 to 8As shown in the figure, the moving component includes a connecting rod 19 embedded inside the fixing plate 12. There are two connecting rods 19. The bottom ends of the two connecting rods 19 are both installed at the top end of the second clamping plate 18. The second clamping plate 18 is rotatably connected to the connecting rod 19. A gear 20 is threadedly connected to the outer wall of one of the connecting rods 19. The gear 20 is rotatably installed inside the fixing plate 12. One side of the gear 20 is meshed with a rack plate 21. The rack plate 21 passes through the inside of the fixing plate 12 and extends to one side of the fixing plate 12. A limiting rod 24 is provided at one end of the rack plate 21. The limiting rod 24 is fixedly installed on the side wall of the side plate 2.

[0048] After the display module at the top end of the moving seat 5 is detected, it moves towards the side away from the top plate 3. The movement of the moving seat 5 drives the movement of the rack plate 21. When the end of the rack plate 21 moves and contacts the limiting rod 24, it is forced to slide into the inside of the fixing plate 12. The movement of the rack plate 21 drives the gear 20 to rotate. The rotation of the gear 20 drives the connecting rod 19 to move upward. The movement of the connecting rod 19 drives the second clamping plate 18 to move, so that the second clamping plate 18 moves towards the side away from the first clamping plate 16, releasing the display module, which is convenient for the staff to remove the detected display module.

[0049] As Figure 7 shown, the connecting rod 19 is slidably connected to the fixing plate 12.

[0050] As Figure 7 and Figure 8 shown, a slider 22 is fixedly connected to one side of the rack plate 21. The slider 22 is slidably installed inside the fixing plate 12. A first spring 23 is provided on one side of the slider 22.

[0051] When the rack plate 21 slides into the inside of the fixing plate 12, the movement of the rack plate 21 drives the movement of the slider 22. The movement of the slider 22 causes the first spring 23 to be deformed and store elastic potential energy. When the rack plate 21 separates from the limiting rod 24, the elastic potential energy is released through the first spring 23 to make the rack plate 21 move back to its original position;

[0052] The limiting rods 24 are arranged on both sides below the top plate 3. When the moving seat 5 is located below the top plate 3, the second clamping plate 18 and the first clamping plate 16 keep the display module in a clamped state. When the moving seat 5 is removed from below the top plate 3, the second clamping plate 18 moves again to release it.

[0053] As Figures 1 to 3 shown, a supplementary light 25 is provided below the top plate 3. A connecting plate 26 is fixedly connected to one side of the supplementary light 25. The connecting plate 26 is installed inside the side plate 2.

[0054] When detecting defects in the display module, a supplementary light 25 provides stable and uniform light, reducing interference from external light, making the details on the display module clearer and more visible, and helping the machine vision system complete the image acquisition and processing process more quickly.

[0055] As Figure 3 shown, a fixing rod 27 is slidably connected to the top end of a connecting plate 26. The fixing rod 27 is fixedly installed inside a side plate 2, and a second spring 28 is arranged on the outer wall of the fixing rod 27.

[0056] The supplementary light 25 can move up and down a certain distance. When the display module is flipped, if the module contacts the supplementary light 25, it can drive the supplementary light 25 to move, allowing enough space for the display module to rotate;

[0057] When the supplementary light 25 moves, the connecting plate 26 slides inside the side plate 2. The movement of the connecting plate 26 deforms the second spring 28 to store elastic potential energy, and the elastic potential energy is released through it to reset the supplementary light 25.

[0058] A detection method for a display module defect detection device includes the following steps:

[0059] S1: When detecting defects in the display module, first place the display module to be detected between a first clamping plate 16 and a second clamping plate 18, and then rotate a rotating block 15. The rotation of the rotating block 15 drives the rotation of a second threaded rod 14. The rotation of the second threaded rod 14 drives the movement of a connecting block 13. The movement of the connecting block 13 drives the second clamping plate 18 to move downward, so that the second clamping plate 18 cooperates with the first clamping plate 16 to clamp the display module;

[0060] S2: After the display modules on the tops of a plurality of moving seats 5 are all installed, then control a first motor 7 to start through a PLC. The start of the first motor 7 drives the rotation of a first threaded rod 6. The rotation of the first threaded rod 6 drives the movement of the moving seat 5, so that the moving seat 5 carries the display module to be detected and moves below an industrial camera 4, and the industrial camera 4 detects the defects of the display module;

[0061] S3: After one side of the display module is detected, control a second motor 11 to start through the PLC to drive a rotating shaft 10 to rotate. The rotation of the rotating shaft 10 drives a mounting plate 9 to rotate. The rotation of the mounting plate 9 drives the first clamping plate 16 and the second clamping plate 18 to clamp the display module and flip it 180 degrees to detect the other side of the display module. After the other side of the display module is detected, start the second motor 11 again to make it flip back to the original position;

[0062] S4: Then, start the first motor 7 again through PLC control and move it through the moving base 5, so that the detected display module moves to the side away from the top plate 3. The movement of the moving base 5 drives the movement of the rack plate 21. When the end of the rack plate 21 moves and contacts the limit rod 24, it slides into the interior of the fixed plate 12 under force. The movement of the rack plate 21 drives the rotation of the gear 20. The rotation of the gear 20 drives the connecting rod 19 to move upward. The movement of the connecting rod 19 drives the movement of the second clamping plate 18, so that the second clamping plate 18 moves to the side away from the first clamping plate 16, releases the display module, and the staff takes it out. The undetected display module moves below the top plate 3 and continues to be detected;

[0063] S5: Finally, repeat the above steps for continuous detection.

[0064] Although the embodiments of the present invention have been shown and described, those of ordinary skill in the art can understand that various changes, modifications, substitutions, and variations can be made to these embodiments without departing from the principles and spirit of the present invention. The scope of the present invention is defined by the appended claims and their equivalents.
