-
摘要: 采用视觉检测技术及图像处理技术相结合的方法，实现了直径约为5 μm钨丝丝阵负载单丝的垂直度，相邻两根微丝的间距，丝阵上是否有异物，丝是否断裂等装配参数的自动、连续、无损检测。研究了视觉检测系统图像采集和配置方法，构建了Z箍缩丝阵负载装配参数视觉检测系统。实验结果表明，视觉检测系统的检测精度达2 μm，可以精确地检测出丝上异物和丝是否断裂，满足Z箍缩丝阵负载装配参数的检测要求。Abstract: The use of visual inspection and image processing technology has implemented the automatic, continuous and non-destructive inspection of 5 μm tungsten wire-array assembly parameters, i.e., the straightness of single wire, the distance between two contiguous wires, and whether foreign body and rupture exist. Image collection and configuration method of this visual inspection system is studied, and a visual inspection experiment system has been built for inspecting Z-pinch wire-array assembly parameters. The results show that the system has the optimal inspection precision of 2 μm and can inspect foreign body and rupture on wires, which can meet the requirement of assembly parameter inspection for Z-pinch wire-arrays.
