Checking for missing O-rings or O-ring misalignment during EGR valve assembly.

1. The color tone variation in die-cast parts caused detection errors when standard machine vision equipment was used for detection. The Pattern Search tool of the XG Series ensures stable detection even when background colors vary. 2. The XG Series has ultra-compact, 12 mm (0.47) square, cameras and side-view attachments that enable sensors to be mounted in small spaces.


Missing O-rings and O-ring misalignment were previously checked visually before press-fitting. It was sometimes difficult to see the parts, and the method was inconsistent. Using machine vision equipment ensures a stable inspection of all parts.
