Image Sensors Used to Inspect Defects in Screws and Bolts
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.
