Abstract

Each transistor 10 is fed base-down into a funnel 12 having an opening 13. The transistor base 14 of magnetic material drops into an insulating socket 15 which is secured to a member 16 rotatable about its horizontal axis by a motor (not shown). Extending into the base of the socket is a steel disk 17 secured to a steel shaft 18 which is arranged to be rotated

Transistor Lead Straightener

Each transistor 10 is fed base-down into a funnel 12 having an opening 13. The transistor base 14 of magnetic material drops into an insulating socket 15 which is secured to a member 16 rotatable about its horizontal axis by a motor (not shown). Extending into the base of the socket is a steel disk 17 secured to a steel shaft 18 which is arranged to be rotated

by a motor 19 through frictional drive 20 21 and 22. A winding 23, when energized, magnetizes the shaft and disk. A lug 24 on the base 14 is adapted to be seated in a recess 25 in the socket 15 to complete an electrical circuit through the base of the transistor.

When a transistor rests with its base 14 in the socket 15, the combined rotation of the shaft 18 by motor 19 and the attraction afforded by disk 17, when magnetized by the winding 23, serve to rotate the transistor by its base and seat it in the socket with the lug 24 in the recess 25. This then controls a circuit which turns off the motor 19 and energizes the motor (not shown) which rotates the member 16 clockwise 90 degrees to bring the kinked leads 27 within the spaced plates 26. Next, suitable controls operate the hydraulic valve 34 which elevates the anvil 29, spaced fingers 30 and bayonets 31 to a horizontal position. Then the oppositely located valves 28 are actuated to squeeze the plates 26 into engagement with the transistor leads, following which the valve 35 is actuated to lower the hammer 32 and bring finger...
