In recent years, auto parts manufacturers have also been developing rapidly.

[0003] When screening auto parts, most of them are screened by visual inspection. The visual inspection equipment includes a conveyor belt, an electric push rod and a CCD camera. Auto parts are placed on the conveyor belt and photographed when passing by the CCD camera. The controller analyzes the picture to detect the appearance of the parts. Qualified parts are sent to the good product warehouse at the end of the conveyor belt, while defective parts are pushed to the defective product warehouse by the electric push rod during the transportation process to achieve screening.

During the screening process, the parts cannot rotate, and a single camera cannot effectively determine the positions around larger parts, which can easily cause screening errors. Therefore, an automobile parts screening device is needed to assist in solving this problem. Utility Model Content
