Card Pickup After Profiling
An arrangement is described to pick up integrated circuit cards after profiling,
which requires little time to be set up for a new part number.
The basis for card pickup, as shown in Fig. 1, is to pierce a pre-drilled hole 10
in the card 11 and retain the card from the bottom side. The card must be
designed with 1 to 4 holes of about .250". The cards are retained by 2 to 4 flat
springs 12 which slide inside a tubing 13. A step-by-step sequence is shown in
The taper on the flat springs 12 allows cards to be misplaced slightly (.1").
The flat springs 12 are extende applying a force at the top of the tubing 13.
Details of the pickup device are shown in Fig. 2.
A number of these devices would be bolted to a plate. Four of these plates
would be bolted to a gantry tool which is located directly above the profiled cards.
A universal force plate or individual solenoids or air cylinders would be positioned
above these plates 31 to actuate the devices as shown in Fig. 3.
Plates 30 and 31 travel downward together to pierce the hole(s) in the cards.
Plate 30 travels downward to spread the flat springs and retain the cards. Both
plates 30 and 31 lift together and move cards to where they are to be placed.
Plate 30 lifts and the cards are released.
