基于 HALCON 的点胶质量检测系统设计

目的针对现有点胶质量检测过程中存在的检测成本高、速度慢、精度低等问题,提出一种基于HALCON的点胶质量检测方案。方法通过图像去噪、模板分析、图像分割以及形态学处理等手段获得待检工件胶水轮廓,将其与标准合格工件胶水轮廓中心线作差集操作,以检测是否存在断胶现象,并根据胶水轮廓的宽度值判断是否存在波浪胶。结果实验结果表明,该方案能够快速、准确、有效地判别出合格品,检测出波浪胶、断胶等问题,检测准确率达99.6%,平均检测时间约为475 ms。结论该方案的检测精度和检测速度均符合工业生产线的检测要求,能够应用于实际生产中。

Design of Glue Dispensing Quality Detection System Based on HALCON

The work aims to propose a glue dispensing quality detection scheme based on HALCON with respect to the problems of high detection cost, slow speed and low precision in the process of existing glue dispensing quality detection. By means of image de-noising, template analysis, image segmentation and morphological processing, the glue contour of the sample to be tested was obtained. The difference set with the qualified glue''s centerline was operated to check for the broken glue and tell if wave glue existed according to the width of glue contour. The experimental results showed that the scheme could quickly, accurately and effectively determine the qualified or unqualified products, and detect such problems as wave glue and broken glue. The detection accuracy rate was 99.6% and the average detection time was about 475 ms. The detection accuracy and detection speed of the scheme meet the detection requirements of industrial production line, and can be applied in the actual production.
