Abstract

This article introduces an auto aligning drilling machine for PCB based on computer-vision. Furthermore, the tec. such as perfectly real-time inspection of image center based on least square method, two-directional mechanism resume, auto- calibration and auto-correction home is also included in this article. The accuracy of drilling is analyzed. It was indicated by theory and re-inspection that the accuracy of drilling machine is smaller than 25 micrometers , repeatability is smaller than 5 micrometers . So we can say that it is good to meet the demand of high accurate positioning hole of PCB.
