Semiautomatic Vision Inspection System

      Disclosed is a device that inspects electronic card assemblies
by comparing a known good card with the production card using two
video cameras.  The cameras are mounted on an X/Y assembly which is
integrated with a 22" conveyor and is part of the assembly conveyor
system.  The figure shows the arrangement of the equipment.

      The card is conveyed from the assembly tool and stops on the
inspection conveyor section.  The operator moves the camera assembly
by hand and scans the the area of the card to be inspected.  On the
video, the operator observes the production card and the known good
card simultaneously utilizing a split screen.  A direct comparison is
made to determine:  1) missing parts; 2) off registration parts; and
3) wrong part numbers.  Other applications include the verification
of white i.d.  numbers and paste application quality inspection.

      This device is unique because it is extremely inexpensive
compared to other off-the-shelf video inspection devices and is
integrated in an existing conveyor system.
