The placement rack 501 is provided with a plurality of grooves 502 for placing cemented carbide workpieces 11, and each groove 502 can correspond to a cemented carbide workpiece 11. The feed drive mechanism is arranged at the bottom end of the placement rack 501. The feed drive mechanism is used to drive the placement rack 501 to move so that the cemented carbide workpieces 11 at different positions reach a predetermined grasping position. The detection device includes a plurality of sensors, which are placed in the groove 502. The sensor is used to detect whether the cemented carbide workpiece 11 placed in the groove 502 is taken away.
