ABSTRACT:
The pickup and insert tool is used during the automated assembly of small motors and other products that require tie bolts, screws, and similar fasteners. Different length tie bolts are handled without adjusting the tool. The fastener is picked up from a holder and held between a pair of spring loaded jaws. The motion to insert the tie bolt is provided by a movable rod which also accommodates the different lengths of the bolts.
