Silicon wafer removing device and silicon wafer conveying system

The utility model discloses a silicon wafer rejecting device and a silicon wafer conveying system, the silicon wafer rejecting device of the embodiment of the utility model comprises a rack, a swing frame, a conveying assembly and a telescopic assembly, and the rack is provided with a first friction surface; a second friction surface is arranged on the swing frame, and the swing frame is hinged to the rack; the conveying assembly is arranged on the swing frame and used for conveying silicon wafers in the length direction of the swing frame. The two ends of the telescopic assembly are hinged to the rack and the swing frame correspondingly so as to drive the swing frame to be switched between the first position and the second position. At the first position, the length direction of the swing frame is parallel to the length direction of the rack, and the second friction face abuts against the first friction face in the height direction of the rack. And at the second position, the length direction of the swing fr
