Detecting bead positions

Detecting bead positions

Detecting bead positions before bending.

Machine vision equipment can provide surface inspections over a wide area. The Stain tool and Fine Color can be used to detect bead positions from the degree of color change. This feature enables the sensor to handle variations without having to adjust the sensitivity for each lot.


Fiber sensors or color sensors were previously used to detect bead positions. This method caused detection errors when spots or variations in surface conditions between lots were incorrectly identified as beads. Using machine vision equipment prevents the operation errors responsible for defects being missed and line shutdowns.
