Automatic sorting is a process of automatically classifying and sorting electronic chips by using machine vision, robotics and artificial intelligence, which can process a large number of chips in a short time.

The proximity sensor 58 detects the passing of the chip. When the detection is unqualified, the chip is pushed into the waste box 6 by the push plate 57 after the detection. If the detection is qualified, the chip continues to convey and finally falls onto the conveyor belt 7 to be conveyed to the subsequent work section for processing. The worker periodically cleans the waste box 6.
