After the screw is detected to be qualified, when the screw has passed 300 pulses, it means that the screw has reached the blowing port 4, and the blowing port 4 starts working to blow the screw out and rotate the turntable. In this way, it is possible to quickly detect whether each screw produced is qualified, thereby greatly improving the success rate of screws leaving the factory. The number of detection positions and camera components can be set according to the shape of the screw to be detected.
