视觉系统在检测对称器件倒反入载带中的应用

Application of Vision Inspection System for Symmetrical Device Misplacement on Packing Tape

针对传统分立器件测试包装时,自动视觉检测一般只检测器件塑封体和引脚等外观,对称器件在替补时可能存在方向倒反的问题,引入了视觉检测的方法。通过检测器件打印码来判断器件方向是否正确。通过具体设计并在实际设备上安装和实验分析,阐述了如何通过视觉检测出载带中的倒反器件,有效提升了产品质量。

During the testing and packaging process of traditional discrete devices, the auto vision inspection system only detects plastic packages and lead defects. For symmetric devices, misplacement or incorrect placement may be a problem. The vision detection method proposed in the paper determines the direction of the devices by the marking codes. Experiment results show that the method effectively solve the problem and thereby improve the product quality.
