Method of Electronic Component Location, Grasping and Inserting Based on Machine Vision

Aiming at the problems of low efficiency, high cost, missing or wrong insertion of labor in PCB production, a method of electronic component location, grabbing and inserting based on machine vision is proposed. By building the machine vision system, three industrial cameras cooperate with dome light sources to take images of the whole components, the pin features of components and the jack features of PCB board respectively. After image acquisition, image processing is carried out on VisionPro 9.0 software platform, which mainly completes feature extraction of component pins and PCB board jacks, and coordinates positioning. Then, coordinate transformation is carried out by nine-point calibration method to guide the manipulator to complete the work of location, grabbing and inserting. Through the running test, the system has a fast grabbing speed and inserting speed. The error inserting rate, missing inserting rate, bad product rate and inserting precision all reach the standard, and the working efficiency is three times that of the manual.
