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。

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.
