Filed:

Nov 8, 2002

Appl. No.:

10/291074

Inventors:

David W. Duquette - Minneapolis MN, US
Paul R. Haugen - Bloomington MN, US
David Fishbaine - Minnetonka MN, US
John D. Gaida - Victoria MN, US
David D. Madsen - Lakeland MN, US
Theodore Paul Dale - Minneapolis MN, US
Todd D. Liberty - Apple Valley MN, US
Brant O. Buchika - Minnetonka MN, US
Scott D. Roth - Newburyport MA, US
Thomas W. Bushman - Marblehead MA, US

Assignee:

CyberOptics Corporation - Golden Valley MN

International Classification:

G01B 11/14

US Classification:

356614, 356400

Abstract:

Improved component placement inspection and verification is performed by a pick and place machine. Improvements include stereovision imaging of the intended placement location; enhanced illumination to facilitate the provision of relatively high-power illumination in the restricted space near the placement nozzle(s); optics to allow image acquisition device to view the placement location from an angle relative to a plane of the placement location, thereby reducing the possibility of such images being obstructed by the component; techniques for rapidly acquiring images with commercially available CCD arrays such that acquisition of before and after images does not substantially impact system throughput; and image processing techniques to provide component inspection and verification information.
