[0030] Working process and principle:

[0031] When testing the products, several products are placed on the loading tray 6, and then the loading tray 6 is placed in the placement space at the starting end of the detection conveyor belt 3. Then the detection conveyor belt 3 transports the loading tray 6 to one side of the manipulator 7 and stops. Then the manipulator 7 drives the rotating grabbing assembly 11 to grab the products on the loading tray 6. When grabbing, one is first grabbed by the gripper cylinder 1103 on one side, and then the rotary motor 1101 is rotated to make the two gripper cylinders 1103 exchange positions, and then the gripper cylinder 1103 that has not been gripped grabs another one, and then the manipulator 7 moves on the moving belt. The movable jaw cylinder 1103 moves to the receiving seat 14, and firstly puts the product clamped by one of the jaw cylinders 1103 into the detection chamber, and then the transverse movement module 13 drives the receiving seat 14 to move to the bottom of the visual camera 9, and the visual camera 9 performs visual inspection on the product. After the inspection is completed, the transverse movement module 13 moves back to its original position, and then the jaw cylinder 1103 clamps the inspected product, and then the rotating motor 1101 is used to rotate the other jaw cylinder 1103 to the receiving seat 14, and then the product on the jaw cylinder 1103 is put into the detection chamber for inspection again;

[0032] When both products have completed the inspection, if both products are qualified, the robot 7 will put both products back into the loading tray 6 and re-grip two other new products for inspection. If it is detected that one of the products is unqualified, the robot 7 will put the unqualified product into the NG conveyor belt 4 for NG unloading, and the qualified products will be put back into the loading tray 6.

[0033] The utility model is provided with a detection conveyor belt 3, a manipulator 7, an NG conveyor belt 4 and a visual inspection component. By placing a plurality of products into a loading tray 6 and then into the detection conveyor belt 3, the products can be conveyed through the detection conveyor belt 3. Subsequently, the products are clamped and moved to the visual inspection component by the manipulator 7. The products are visually inspected by the visual camera 9 of the visual inspection component. This is fully automated, does not require manual operation, has high loading efficiency and inspection efficiency, and can automatically classify and unload products for NG after the product inspection fails.

[0034] The above is only a preferred embodiment of the present invention. The protection scope of the present invention is not limited to the above embodiments. All technical solutions under the concept of the present invention belong to the protection scope of the present invention.
