Abstract

Improved lead straightening results when a kneading-like action is initiated at the junction of the component and lead, so that the free lead end is pushed outwardly from the component. The starting of straightening at the base of the component usually permits the straightener to begin with the straightest portion of the leads.

Lead Straightener

Improved lead straightening results when a kneading-like action is initiated at the junction of the component and lead, so that the free lead end is pushed outwardly from the component. The starting of straightening at the base of the component usually permits the straightener to begin with the straightest portion of the leads.

Referring to Figs. 1 and 2, the lead straightening mechanism is shown in use with a transistor 1 which is positioned for lead straightening along track 2 so as to be engaged by oppositely actuated carrier units 3, mounted for movement toward and away from the transistor 1. The carriers 3, for example, may be actuated by a cam and linkage arrangement as shown. Each carrier assembly 3 is the mirror image of the other and supports a plurality of opposing pairs of inserts 4, 5 and 6, which have complementary end configurations as shown in Fig. 2.

Each set of slides, beginning with the top pair as shown in Fig. 1, is displaced so as to successively engage the component leads as each slide in a pair moves toward its mating slide. Each carrier base 7 has mounted for reciprocating movement therein a rack 8 in engagement with sector gear 9 which is cut out, so as to hold its plurality of mating inserts in the staggered relation along edge 10.

Base 7 also has a spring loaded plunger 11 engaging a slidable block 12, held on base 7 by screw 13. Also included is spring 14 held in position in blind hole 15 by screw 16 secured in rack 8...
