Abstract

This device is for cutting a strip of mounted components into lengths comprising parts of a printed circuit. Strip 10 is a thin metallic component holder with clip formations 11 stamped from it for grasping the central body portion 12 of resistances, diodes, etc., so that they are closely spaced in vertical standing positions. By spot welding the upper leads to tabs 14, a group of components, upon being cut by the device, can be positioned with their lower leads extending into holes in printed circuit board 15. These leads are then bent over and soldered to leads on the back of board 15.

Component Strip Cutter

This device is for cutting a strip of mounted components into lengths comprising parts of a printed circuit. Strip 10 is a thin metallic component holder with clip formations 11 stamped from it for grasping the central body portion 12 of resistances, diodes, etc., so that they are closely spaced in vertical standing positions. By spot welding the upper leads to tabs 14, a group of components, upon being cut by the device, can be positioned with their lower leads extending into holes in printed circuit board 15. These leads are then bent over and soldered to leads on the back of board 15.

Strip 10 containing the components is stored on reel 16. From this it is fed to a cutting position under control of perforated tape 17 which is read at sensing station 18. Tape 17 actuates supervisory circuitry 19. This, in turn, controls the amount of strip to be fed and also a knife for cutting the strip into lengths.

Motor 20 drives shafts 21, 22 and 23 through a system of belting and gears to actuate the tape feed, cutter, and strip feed, respectively. Clutch 24 drives feed sprocket 25 through shaft 23 and worm drive 26 to feed the strip to a cutter. Upon signal from the tape, clutch 24 is released and clutch 27 is actuated rotating shaft 22 to drive an eccentric 28. This oscillates yoke 30, in turn rocking shaft 31 to operate knife 32. Knife 32 thus cuts the length of strip just fed which drops down chute 33 into storage tray 34, from which it is withd...
