Research and Develop on PCB Defect Intelligent Visual Inspection Robot

Abstract

In order to realize the fast detection of the printed circuit board's quality, a set of PCB defect intelligent automatic detection device based on machine vision is analysed and designed. The paper introduced the robot system construction, machine system, electronic control system, the design and realization of vision imaging system, software used a fast iterative algorithm for image segmentation based on 2D maximum between-cluster variance, using the template matching method for PCB image of the automatic detection and recognition defects. Experiment results on model machine show that the design of the intelligent visual inspection robot can detect PCB defect exactly and effectively, it also can be used in the actual PCB online detection.
