ABSTRACT:
Detachably mounted on a sliding table are a plurality of part tape or belt feed units each of which intermittently feeds to a lead wire cutting station a part tape or belt holding a large number of parts of the same type, each of which has lead wires extended in opposite directions and coaxially of a main body of the part and attached adjacent to their ends to parallel strips of tape or belt in equidistantly spaced apart relationship with the lead wires of the adjacent parts. The sliding table moves in either direction so that the desired part tape or belt feed unit is moved to a part feed position at which the desired part tape or belt feed unit feeds the part to the cutting station. At the cutting station a cutter unit cuts off from the part tape or belt the lead wires of the part, thereby separating therefrom the part having lead wires of a predetermined length, and the lead wires are bent in the same direction. Thereafter the cutter unit is rotated and moved to a lead wire insertion position, and a pusher in the cutter unit pushes the shoulder portions of the lead wires so as to insert them into predetermined apertures in a printed circuit board. The lead wires of parts of any sizes and configurations may be inserted, and the cutter unit effects the cutting, forming and pushing toward the insertion position of the lead wires, whereby the lead wire insertion speed may be substantially increased.
