Abstract

Make a study of real-time, automatic positioning of Printed Circuit Board (PCB) jack centers. Bwlabel algorithm is used to deal with the PCB images under the condition of backlighting. According to the feature of Bwlabel algorithm extract and match the jack center indexes for every component, calculate the jack center connection angle, and generate jack center positioning data, figuring out the jack center coordinates. Combining with camera parameters, both the radial and tangential lens distortion are corrected, revising the coordinates of jack centers. At last, an automatic PCB jack positioning system is developed.The system experiment results show that the requirement of production has been met with accuracy of positioning that minimum jack diameter of 2.32mm and average time of 0.21s, which provides coordinates information for automatic assembly operation by manipulator.
