Abstract

A mechanical device aligns an IBM/Milton Ross flatpack carrier and spreads its part-retaining grippers in order to load a flatpack into the carrier for subsequent surface mounting onto a printed circuit card. The aligner/spreader assembly 2 is seen in the drawing in an exploded view and consists of an outer member 3, an inner member 4, a punch 5, a spring 6 and a tapered screw 7. The inner member 4, which is mated to outer member 3 of assembly 2 by a slip fit is securely fastened to punch 5 by a tapered screw 7 when assembled. The inner member 4 is keyed to punch 5 by milled slots 8 in inner member which inserts between posts 9 of mating punch 5 to maintain correct alignment of the angled surfaces 10 of inner member 4 to spread part-retaining grippers 11 of carrier 1.

Ibm/Milton Ross Carrier Aligner/Spreader for Flatpacks

A mechanical device aligns an IBM/Milton Ross flatpack carrier and spreads its part-retaining grippers in order to load a flatpack into the carrier for subsequent surface mounting onto a printed circuit card. The aligner/spreader assembly 2 is seen in the drawing in an exploded view and consists of an outer member 3, an inner member 4, a punch 5, a spring 6 and a tapered screw 7. The inner member 4, which is mated to outer member 3 of assembly 2 by a slip fit is securely fastened to punch 5 by a tapered screw 7 when assembled. The inner member 4 is keyed to punch 5 by milled slots 8 in inner member which inserts between posts 9 of mating punch 5 to maintain correct alignment of the angled surfaces 10 of inner member 4 to spread part-retaining grippers 11 of carrier 1. The carrier 1 is fed down a circulatory track (not shown) of a vibratory feeder bowl (not shown) where the carrier 1 is oriented so that the correct lead one position of flatpack is achieved. The carrier 1 is stopped at the end of the track (not shown) and positioned over the aligner/spreader assembly 2, as seen in the drawing. The carrier is now roughly aligned. The aligner/spreader assembly 2 is actuated upward on its Z axis until the tapered surface 12 of the outer member 3 engages the side pads 13 of carrier 1. As tapered surface 12 continues upward against side pads 13 of the carrier 1, it is aligned in the Y direction. The outer member 3 o...
