[0042] In the description of the present invention, it is necessary to understand that the indicated orientation or positional relationship is based on the orientation or positional relationship shown in the accompanying drawings, and is only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation on the present invention.

[0043] Working principle:

[0044] The quality inspection device for wristband production, when in use, starts the hydraulic cylinder 2, drives the support plate 3 to move, thereby drives the support rod 4 and the conveyor belt 6 to rise and fall, automatically adjusts the height of the conveyor belt 6 according to the height and usage habits of the staff, places the wristbands to be inspected on the surface of the conveyor belt 6 in turn, starts the conveyor belt 6, and conveys the wristbands. When the wristbands move below the quality inspection camera 24, the conveyor belt 6 stops, the quality inspection camera 24 takes a picture of the wristbands, and compares them with qualified products, so as to conduct a comprehensive inspection of the wristbands. When the inspection is qualified, the conveyor belt 6 continues to work and conveys the wristbands. When defective products are detected, the electric telescopic rod 21 drives the push plate 22 to descend, so that the push plate 22 fits with the conveyor belt 6, and the linear reciprocating motor 20 drives the push plate 22 to move, pushes the defective products into the collection box 10, and automatically completes the rejection and collection of the defective products. After the defective products are rejected, the electric telescopic rod 21 drives the push plate 22 to reset, and the linear reciprocating motor 20 drives the electric telescopic rod 21 to reset;

[0045] The image of the wristband on the surface of the conveyor belt 6 is collected by the quality inspection camera 24, and the number of wristbands is counted at the same time. When the push plate 22 pushes the defective products into the collection box 10, the push plate 22 squeezes the pressing counter 18, so as to count the number of defective products. The total number of wristbands, the number of defective products and the defective rate can be displayed in conjunction with the display 31, so as to more intuitively display the production quality of the wristbands. At the same time, the setting of the dual display screens in the display 31 can simultaneously display the images of the inspected wristbands, so as to make it more convenient for the staff to observe the inspected wristbands.

[0046] When defective products accumulate in the collection box 10, the forward and reverse motor 12 is started to drive the guide screw 13 to rotate, thereby driving the guide block 14 and the scraper 15 to move, automatically pushing the defective products in the collection box 10 to move, and flattening the defective products in the collection box 10 to prevent the defective products from piling up in the same position of the collection box 10 and affecting the subsequent collection of the defective products.
