[0031] 4) Photographing the occluded area: Through the vacuum adsorption device, suck the protective film on the upper surface of the packaging box and lift it up a certain height to separate the label from the product, forming a certain gap. Use the second photographing device to photograph the occluded area of the product through the gap between the label and the product. The second photographing device cooperates with the rotating device. After each visual inspection in one direction is completed, the rotating device rotates a certain angle and then repeats the photographing. The occluded area images of the product are obtained comprehensively in multiple directions, and the occluded area images of the product are transmitted to the system. In this embodiment, it rotates 180° and takes pictures twice to obtain image information.
