ABSTRACT:
This invention describes apparatus and method for inserting terminal pins into a circuit board regardless of the length of the pins or the thickness of the board. Loose pins are held in a suitable tray on a fixed plate having a plurality of holes similarly positioned with the holes on the circuit board. Located below the fixed plate is a movable pin assembly plate having a plurality of pin locators each positioned under a hole and each having a central opening for accepting a pin and holding a pin in an upright position. Vibrating the fixed plate causes the loose pins to fall through the holes in the plate and into the pin locators which hold the pins. A circuit board held by a backup plate is positioned over the fixed plate at a distance away from the fixed plate so as not to interfere with the excess loose pins lying on the plate. Moving the pin assembly plate in an upward direction causes the pins held in each of the pin locators to be inserted into the terminal board.
