The second inspection camera 512 on the second inspection station 53 inspects the upper surface of the material. After inspection, the material is transferred to the next inspection station. There are three second inspection cylinders. The device can simultaneously grip and rotate three materials for inspection, improving inspection efficiency. After the third inspection camera 513 with the fourth inspection station 55 completes the inspection, based on the judgment result, the third cylinder gripper 63 is driven by the third transverse drive component 61 to place it on the corresponding good product discharge mechanism 7 or defective product discharge mechanism 8.
