ABSTRACT:
A system for locating and determining the orientation of fasteners in hard disk drive spindle assemblies utilizes a sensor system that facilitates an automated rework process for the spindle assemblies. The screw locating system identifies the locations of the screws in a spindle and generates a signal for a screw driver system to align tool bits with the screws. The sensor is highly advantageous when reworking spindle motors with opaque labels that cover and/or block the fasteners. The present invention overcomes the drawbacks of prior art techniques by using a screw locating system that is based on a selected capacitance probe without requiring the use of timing features.
