ABSTRACT

In the process of PCB board production, it is necessary to accurately measure the contour dimensions of the PCB board and the dimensions of various types of wires, holes, or slots on the PCB board to avoid a large number of defective products flowing into the subsequent production process. In existing technology, the measurement of the dimensions of wires, holes, or slots on the PCB board mostly relies on manual work, which has the problems of low measurement efficiency and high measurement error rate, Unable to meet the efficient and high-quality production needs of PCB boards. This article proposes a method and device for effectively utilizing OpenCv to detect PCB board size. This device is based on an optical image measurement system, combined with the template matching method in OpenCv, and can automatically complete forming inspection and size measurement by scanning multiple PCB boards by one time.This device can complete measurement evaluation, report generation, and SPC data analysis for multiple PCB boards, achieving high automation and significantly improving measurement accuracy system.
