Electronic metal sheets are widely used in key components of the 3C industry, such as circuit boards and connectors. Defect detection is an essential step in the production of electronic metal sheets.

The first 2D carrier, the second 2D carrier, and the 3D carrier are positioning carriers with identical structures. The positioning carrier includes a placement area for placing the product, and limiting blocks are provided on the four sides of the placement area. The carrier has a Y-direction clearance groove arranged along the Y direction, which runs through both sides of the carrier, thereby facilitating the second 2D inspection mechanism to inspect the product's external dimensions from the side. The Y-direction clearance groove corresponds to the two sides of the product. The carrier also has a Z-direction clearance groove that runs vertically through the product, which corresponds to the four corners of the product, thereby facilitating the first 2D inspection mechanism to inspect the product's external dimensions from above.
