Mechanical Structure Design and Application for PCB Detection System

PCB defect detection based on AOI is the key technology to realize the automation production of PCB, and the mechanical structure design of the recognition system is one of the most important technologies in the detection system, too. By modeling the main hardware of mechanical structure of the system, we have integrated the whole hardware structure of the detection system. In this paper, we firstly design the general structure of the PCB recognition system. Then, we propose five axis positioning platform and PCB installation device. Finally, the designs of PCB belt conveyor and image acquisition device are completed. By using the integrated hardware structure combined with software control, we can realize intelligent recognition for PCB detection.
