Image Sensors Used to Inspect Defects in Screws and Bolts

Case Number 123

last update: April 18, 2011

Placement of Sensor Heads on a slight angle causes the thread crests of screws and bolts to shine white. Image Sensors compare the white areas to reliably detect crests.


The area of the registered color is determined to enable detection without affecting the rotation or movements of screws and bolts.
