Description

Technical Field

[0001] The utility model belongs to the technical field of detection equipment, and in particular relates to a segmented product appearance detection device. Background Art

[0002] The product appearance inspection device is a device that can automatically inspect the appearance of products on the production line. It can replace manual inspection for appearance defects, avoiding the problems of manual visual fatigue and missed inspections.

[0003] Conventional appearance defect inspection equipment generally increases the distance between the camera and the product to capture a larger area of ​​the product, allowing for extensive inspection. This increased distance reduces the quality of images captured by the camera, impacting inspection effectiveness. Furthermore, it increases the overall height of the inspection system, increasing its footprint. Utility Model Content

[0016] According to the technical solution, when the conveyor belt transports the product to the position corresponding to the inspection station, the product is located above the pallet. After that, the lifting cylinder drives the lifting frame to drive the pallet to lift the product from the conveyor belt. The transverse screw module drives the transverse frame to drive the support column from the position between the conveyor belts on both sides of the frame through the feed and discharge openings into the inspection station, thereby realizing the transfer of the product on the pallet to the inspection station for appearance inspection.

[0017] In some embodiments, the lifting frame is equipped with a rotary cylinder for driving the support column to rotate;
