[0002] After all the processes of chip resistors are completed, they need to be packaged and placed on the carrier tape to form strips. The packaging will bring scraps, mixed materials, vertical materials, reverse materials, stacked materials, empty materials, skipped materials, and material missing corners. , Carrier tape contamination, carrier tape damage, etc.; a bad resistor, flowing to the customer terminal and pasting it on the circuit board, will cause a bad final product, and may even have a potential safety hazard. Therefore, it is necessary to Packaged chip resistors are tested

[0003] In the packaging inspection after the completion of the chip resistor manufacturing process, most of them are for appearance inspection. The traditional method is to inspect the appearance and defects of the product with the naked eye through a microscope or to inspect the appearance of the product through a CCD detector. Manual inspection will cause fatigue to the naked eye, resulting in unstable quality, low production efficiency, and insufficient accuracy of the inspected appearance. The CCD detector can only inspect one side of the product, so it needs to be inspected twice with the conveyor device, which consumes a lot of inspection time.
