Automatic Pin Inserter

An apparatus is disclosed for automatically inserting pins into circuit cards.

Box l contains preformed program pins located within the field of electromagnets 2. A disk 3 with circumferential slots rotates within box l. Pins standing on end within the magnetic field and properly oriented fall into empty slots in rotating disk 3. As the disk rotates, the pins exit box 1, are pushed out of the slots in the disk, and drop into feed tube 4. They slide down the tube 4 until they come to a stop within the magnetic field of permanent magnet 5. Pins continue to drop into feed tube 4, lining up serially to the level of a tube full sensor (not shown) which stops rotation of disk 3 and hence stops feeding pins.

Electromagnets 2 are then deenergized to allow the pins to assume a prone position so that more pins can attain the proper stand-up orientation when the field of electromagnet 2 is again activated.

During operation, an X-Y positioning mechanism 6 appropriately moves a circuit card 7 into position over an anvil (not shown) which is raised beneath the card to support the card, and provide alignment for the pin as it is force fit into an appropriate hole in the card.

Concurrently, insert head 8 is lowered into position with insert tube 9 directly over the hole in card 7 where the pin is to be inserted. Permanent magnet 10 is then appropriately moved near tube 4 so that the magnetic field of this magnet traps the second pin in line within tube 4....
