摘要
大批量混杂废旧半导体电子元件的自动分选对其后续环保再生处理有很重要的作用,目前多为人工目检,精度不高,效率低。设计了一种基于机器视觉OCR图像处理技术的自动分选系统,系统中废旧半导体电子元件的进料、图像获取、识别分类全流程计算机自动控制。经测试系统技术指标为:分选速率1～2个/秒,识别率70%以上,误识率小于2%。
Automatic sorting with large quantities of mixed and used semiconductor components plays a significant role in follow-up environmental regeneration dispose,mainly through manual visual inspection at present,less precision and low efficiency.We designed a automatic sorting system which is based on machine vision OCR Image processing technology,the whole process of feeding image capture identification and classification is computerized According to the test,the technical specifications of system is: sorted rate is 1～2 per second,recognition rate is more than 70%,misclassification rate is less than 2%.
