Abstract
This paper introduces the automatic optical defect detection and control system of the array camera PCB with PLC as the core and gives the PID control of the PCB motion device, the area camera and the Kalman filter. According to the set process conditions of the industrial assembly line, the whole system is controlled to acquire the defect detection image of the PCB. Compared with the scanning of the line camera, the image acquisition time is reduced, and the detection efficiency is improved.
