Vibratory feeder for dispensing balance correction members for securing to a disc drive disc pack

The present invention relates generally to the field of disc drive data storage devices, and more particularly, but not by way of limitation, to an automated assembly of a disc drive head-disc assembly which includes an automated balance correction station with a vibratory feeder for balance correction members. A vibratory feeder having a component rod assembly with a component key, a component rod and a component load ramp configured to support balance correction members, a vibrator assembly advancing the balance correction members along the component rod assembly to an escapement assembly with an escapement blade allowing one balance correction member at a time to progress onto a component stop which stages and releases the balance correction member into the gravity feed chute that transports the balance correction member to confinement within a component retainer and on to an air activated shutter that dispenses the balance correction member upon activation of a shutter air slide. The vibrator assembly includes a vibration source motor mounted at the center of mass of the vibratory feeder assembly.
