A workpiece handling system for inspection of a workpiece of a type having an elongated cylindrical segment with an enlarged feature in the form of an elongated fastener, wherein the enlarged feature is formed by an enlarged drive head having a radially outward projecting feature which forms an edge or flange-like surface, comprising - a pair of rollers (16,18) inclined with respect to horizontal, each of the rollers (16,18) having a cylindrical outer surface, the pair of rollers (16,18) oriented with parallel axes and rotatable, each of the rollers (16,18) having an upwardly presented end (26,28), wherein the roller ends (26,28) support the enlarged feature of the workpiece, - a drive arrangement for rotating the pair of rollers (16,18) in a rotational direction about their axes, - a slide mechanism enabling the rollers (16,18) to be set at a first separation gap to a second separation gap larger than the first separation gap, - a workpiece transfer mechanism for loading the workpiece onto the pair of rollers (16,18) such that the cylindrical segment is in contact with the roller cylindrical surfaces of both of the rollers (16,18) and the rollers (16,18) support the enlarged feature of the workpiece, whereby rotation of the rollers (16,18) while the rollers (16,18) are set at the first separation gap causes the workpiece to rotate, - a sensor probe positioned in close proximity to the enlarged feature of the workpiece as the workpiece is rotated by the rollers (16,18), whereby the sensor probe is an eddy current sensor probe, and - a workpiece receiving system for handling the workpiece when the rollers (16,18) are set to the second separation gap by the slide mechanism, allowing the workpiece to fall under gravity between the rollers (16,18) onto the workpiece receiving system. - a pair of rollers (16,18) inclined with respect to horizontal, each of the rollers (16,18) having a cylindrical outer surface, the pair of rollers (16,18) oriented with parallel axes and rotatable, each of the rollers (16,18) having an upwardly presented end (26,28), wherein the roller ends (26,28) support the enlarged feature of the workpiece, - a drive arrangement for rotating the pair of rollers (16,18) in a rotational direction about their axes, - a slide mechanism enabling the rollers (16,18) to be set at a first separation gap to a second separation gap larger than the first separation gap, - a workpiece transfer mechanism for loading the workpiece onto the pair of rollers (16,18) such that the cylindrical segment is in contact with the roller cylindrical surfaces of both of the rollers (16,18) and the rollers (16,18) support the enlarged feature of the workpiece, whereby rotation of the rollers (16,18) while the rollers (16,18) are set at the first separation gap causes the workpiece to rotate, - a sensor probe positioned in close proximity to the enlarged feature of the workpiece as the workpiece is rotated by the rollers (16,18), whereby the sensor probe is an eddy current sensor probe, and - a workpiece receiving system for handling the workpiece when the rollers (16,18) are set to the second separation gap by the slide mechanism, allowing the workpiece to fall under gravity between the rollers (16,18) onto the workpiece receiving system.
