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.

Know-How

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

Benefit / Efficiency

Defective items are identified and prevented from reaching the market.
