Abstract
A device is provided for automatically inspecting a fastener for defects prior to its installation in an assembly operation. The fastener is propelled by air or gravity along a feed line. The inspection device is connected in the feed line and has a cam member that is positionable into the fastener's path of travel for blocking it at a certain position. A television camera produces a video image of the stopped fastener, which shows the fastener's actual dimensions. A computer then compares the actual dimensions with the fastener's desired, which are prestored in the computer's memory. If the two substantially match, the fastener is known to be acceptable for installation.
