Description

Technical Field

[0002] Currently, visual inspection systems are mainly used to inspect and screen the appearance and dimensions of parts. They separate good and defective products through a feeding mechanism, which has obvious advantages over manual screening.

[0003] When performing visual inspection and photography of the outer surface of a product, multiple visual inspections are required to ensure that the product is qualified before leaving the factory. When the product is loaded in the tray for transportation, the tray and the products loaded in the tray are prone to displacement, which can easily lead to misjudgment of the visual inspection of the parts, thus affecting the accuracy of the inspection. At the same time, multiple visual inspections need to be carried out at intervals on the conveyor line to avoid mutual interference, but this also greatly increases the area occupied by the equipment, which is not conducive to the company's production.
