[0036] A detection device for LED color patch modules of an LED display screen.

[0037] Example 2

[0038] This embodiment is further limited based on the embodiment 1, wherein.

[0039] Working principle: When the device is used for patch, under the control of the microcomputer 3, the grabbing component 9 will start, and then the lifting cylinder 27 will start first, causing the top plate 28 to lower the position of the electric suction cup 29, and then the electric suction cup 29 will adsorb the workpiece transported by the conveyor belt on one side of the box 1. At the same time, another electric suction cup 29 will adsorb the patch workpiece that has been inspected intact on the clamping component 7, and then the lifting cylinder 27 will continue to start, which will cause the electric suction cup 29 to lift the adsorbed workpiece, and the rear servo 26 will start, and the lifting cylinder 27 will rotate 180 degrees, which will move the processed workpiece out of the box 1 and rotate the unprocessed workpiece into the box 1, and then the lifting cylinder 27 will continue to start, and the top plate 28 will lower the position of the workpiece, so that the processed workpiece falls through the box 1, so that the unprocessed workpiece falls on the clamping component 7 to participate in the patch processing. In this process, under the control of the microcomputer 3, the screw motor 21 at the corresponding position will start, and the piston plate 22 will squeeze the hydraulic oil inside the oil storage chamber 19, and then the hydraulic oil will flow into the two plug-in slots 23. The subsequent hydraulic oil will squeeze the piston block 24, so that the two step blocks 18 move toward each other in the groove 17, so that the distance between the two step blocks 18 changes, so as to support the workpiece put down by the grasping component 9. Later, when the grasping component 9 discharges the material and moves out of the box 1, the patch structure in the box 1 will run to perform patch processing on the workpiece, and when patching, the AI ​​camera 12 will detect the patch process. When a problem is detected, the patch mechanism will pause and return When the workpiece is in the original position, the screw motor 21 at the corresponding position will start, the piston plate 22 will return to the original position, and the oil storage chamber 19 will be in a negative pressure state. Then, in order to ensure the pressure balance inside the oil storage chamber 19, the hydraulic oil inside the plug groove 23 will flow back to the oil storage chamber 19. At the same time, the piston block 24 will retract the step block 18 to the original position of the groove 17 due to the negative pressure inside the plug groove 23, so that the two step blocks 18 no longer support the workpiece. The subsequent workpiece will fall from the groove 17 and the blanking port 10 into the discharge hopper 4 near the feed port 8, realizing the automatic unloading of the workpiece with processing errors. The subsequent grabbing component 9 will continue to load the material, and the patch mechanism inside the box body 1 will continue to move from the original position to perform patch processing. When it is detected that there is no problem with the patch, the control of the microcomputer 3 Under the control, the drive motor 6 will start, the clamping assembly 7 will carry the processed workpiece to rotate under the contact 15, and then the lifting cylinder 13 will start, and the porous socket 14 will carry the contact 15 to the position, so that the contact 15 is in contact with the workpiece on the clamping assembly 7 to meet the purpose of power testing. At the same time, by setting the microcomputer 3, a simple power test of whether the voltage, current or workpiece power supply is operating normally can be achieved. Before the test, the contact 15 can be installed at different hole positions on the porous socket 14 to adjust the distance between the two contacts 15 to meet the purpose of testing workpieces of different specifications. When a problem is found in the test, the screw motor 21 at this location will repeat the above work, and the problematic workpiece will fall into another discharge hopper 4.When a workpiece falls from the clamping assembly 7, the cloth curtain 11 can catch the workpiece, buffering its falling speed and preventing it from directly hitting the inner wall of the discharge hopper 4 and being damaged. When no problems are detected, the drive motor 6 will continue to start, causing the clamping assembly 7 to rotate with the inspected workpiece to the feed port 8. The grabbing assembly 9 will then remove the processed workpiece, place it on the conveyor belt, and place a new workpiece.

[0040] The above description is merely illustrative of certain exemplary embodiments of the present invention. It goes without saying that those skilled in the art will be able to modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and description are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
