10. A method of operating an automatic metal part conveying and inspection device according to any one of claims 1 to 9, comprising:
the conveying belt (11) conveys the metal piece (10) forwards according to the instructions of the PLC;
the PLC controls the conveyor belt (11) to stop conveying, a camera (21) of the detection device starts to work, and whether deviation exists between hole positions and sizes on the metal piece (10) or not, whether the hole positions and sizes are qualified or not and whether the metal piece (10) deviates or not are judged by using a vision system through images; if the metal piece is not qualified, the PLC controls the conveyor belt (11) to convey the metal piece (10) to a waste material box (7) arranged at the downstream end; if the hole position and the size are qualified, starting the metal piece taking and placing device to enable the platform (31) to move to the position above the metal piece (10) from the original point position;
the PLC controls a vertical moving device of the metal piece taking and placing device to drive an electromagnet (32) to move downwards and electrify the electromagnet (32) at the same time, and when the electromagnet (32) contacts and adsorbs a metal piece (10), the electromagnet (32) is driven to move upwards;
after the metal piece (10) is taken up, the PLC prompts whether a direction correcting device needs to be started or not according to the signals judged by the camera (21) so as to adjust the direction of the metal piece (10);
the platform moving device of the metal piece taking and placing device is started, carries the metal piece (10) to move to a set position above the metal piece bearing frame and then stops;
the PLC receives a signal of stopping the platform moving device and a signal of judging whether the metal piece (10) exists or not on the metal piece bearing frame, and sends a command to start the transverse moving device, so that the electromagnet (32) with the metal piece (10) moves leftwards or rightwards to the position of the metal piece lacking (10);
the vertical moving device drives the electromagnet (32) to descend to the proper position and then sends a signal, the PLC enables the electromagnet (32) to be powered off according to the signal, and after the metal piece (10) is placed on the metal piece bearing frame, the vertical moving device drives the electromagnet (32) to ascend.
