After its eddy current sensors failed to detect minute variations in threaded components, MacLean Vehicle Systems chose machine vision sensors to enhanced quality assurance, AZoSensors.com reports.
MVS manufacturing controls engineer T. J. Konieczke said machine vision was selected over retroflective or photodiode sensors, which have higher error rates.
“Konieczke installed two Cognex Checker 101 vision sensing devices at a 450 angle down five inches from two parts on the assembly machine,” according to AZoSensors.com. “The parts are sent to a sensing centre in a fixture and are positioned by a spring-enabled keeper, to have deviations in the height at their positions.”
The vision sensor was installed by dropping inspection tools onto targeted features, utilizing both an edge finder tool and a brightness tool, which detects light reflecting from the threads. ©2010 GlobalFastenerNews.com
