Patent ID: 8100267

Claim:
A sorting device, comprising: a supporting frame; a feed mechanism supporting trays bearing pre-sorted workpieces, and supported by the supporting frame; a classification module comprising a support mechanism, a measurement mechanism, and a marking mechanism, adjacent to the feed mechanism and comprising a plurality of stations to support the workpieces, the measurement mechanism and the marking mechanism being on a same side of the support mechanism and targeting different stations of the support mechanism to measure and mark sort results on the workpieces, wherein the support mechanism, the measurement mechanism, and the marking mechanism are fixed on the supporting frame; a plurality of unloading mechanisms supporting trays transporting workpieces, supported by the supporting frame; and at least one transfer mechanism fixed on the supporting frame, between the support mechanism and the feed mechanism or the unloading mechanisms; wherein the unloading mechanisms are adjacent to the support mechanism, the at least one transfer mechanism relocates the pre-sorted workpiece from the feed mechanism to the support mechanism, or from the support mechanism to a corresponding unloading mechanism according to a sorted criteria of the workpiece.
