基于机器视觉的汽车连接器引脚位置检测

Pin Position Detection of Automobile Connector Based on Machine Vision

汽车连接器的引脚相对于连接器上圆孔的位置必须控制在50μm的误差范围内,才能顺利装配。机器视觉自动化检测代替人工检测可以提高检测的精度和效率。文章研究了汽车连接器引脚位置的机器视觉检测方法,软件使用康耐视的VisionPro,通过C#脚本程序将引脚的坐标显示出来。这种检测方法可以准确判断引脚与圆孔的相对位置是否满足装配要求,极大地提高了检测效率。

The pins of automotive connectors must be within the error range of 50μm relative to the round hole on the connector for smooth assembly.Machine vision automatic detection taking place of manual detection can improve the accuracy and efficiency of detection.This paper studies the machine vision detection method of automobile connector pin position.The software uses VisionPro of Cognex to display the pin coordinates through C#script program.This detection method can accurately judge whether the relative position of pin and round hole meets the assembly requirements,and greatly improve the detection efficiency.
