Patent ID: 8561806

Claim:
A measurement apparatus, comprising: a support frame; a feed mechanism mounted on the support frame to support at least one tray loading at least one workpiece, the feed mechanism comprising a first holding assembly, a first elevation assembly, a second elevation assembly, and a first clipping assembly, the first elevation assembly and the second elevation assembly positioned under the first holding assembly, the first clipping assembly positioned over the first holding assembly, the first elevation assembly elevating the at least one tray loading the at least one workpiece to the first holding assembly, and the second elevation assembly supporting at least one empty tray away from the first holding assembly; a measurement mechanism mounted on the support frame comprising a support stage and at least one calibration head; an orientation mechanism positioned between the feed mechanism and the measurement mechanism comprising a driving member driving a securing assembly; a transfer mechanism mounted on the support frame comprising at least one pickup head; and an unloading mechanism mounted on the support frame comprising a second holding assembly, a third elevation assembly, a fourth elevation assembly, and a second clipping assembly, the third elevation assembly and the fourth elevation assembly positioned under the second holding assembly, the second clipping assembly positioned over the second holding assembly, the third elevation assembly elevating at least one empty tray to the second holding assembly, and the fourth elevation assembly supporting at least one tray loading the at least one workpiece away from the second holding assembly; wherein the feed mechanism and the unloading mechanism are positioned adjacent to the measurement mechanism, the first clipping assembly is capable of transporting the at least one workpiece on the feed mechanism to the orientation mechanism, and the at least one pickup head of the transfer mechanism is capable of transporting the at least one workpiece to the measurement mechanism from the orientation mechanism or to the unloading mechanism from the measurement mechanism.
