Abstract
A silicon wafer sorting mechanism includes a wafer distribution unit, a sorting unit, and a transmission unit disposed sequentially. The sorting unit includes a sorting table with one terminal hinged to the wafer distribution unit. The sorting table rotates and tilts with a point where the sorting table is hinged to the wafer distribution unit. The sorting table and the transmission unit are arranged up and down in dislocation or the sorting table is placed horizontally against the transmission unit, thereby forming two transmission lines in different directions to sort silicon wafers of different types.
