The invention relates to a full-automatic disk-shaped workpiece feeding bin, which belongs to the technical field of machine manufacturing, and comprises a conveying track. The conveying track is mainly formed by support arms and rollers; a workpiece gripping device is arranged above the initiating end of the conveying track; a turnover mechanism is arranged on the conveying track; the workpiece gripping device comprises a frame body, a vertical frame, a three-dimensional movement column and a gripping electromagnet; the three-dimensional movement column conveys a parts onto the conveying track through the gripping electromagnet; a turnover body is arranged on the conveying track and is connected with an output shaft of a turnover motor; a resistance block is arranged in the turnover body; a laser transmitter and a laser receiver are respectively arranged on two sides of the turnover body; the laser receiver is connected with the turnover motor through a signal control device; if the raised face of the disk-shaped parts faces down, the disk-shaped parts can be resisted by the resistance block, and the laser receiver issues an instruction, so that the turnover motor drives the turnover body to clockwise turn over at a 180-degree angle, the posture of the disk-shaped parts is corrected, and the disk-shaped parts is conveyed to a processing station. The full-automatic disk-shaped workpiece feeding bin provided by the invention can be used for automatically gripping the parts and correcting the posture of the parts.
