8. The method for producing and assembling an automobile wiring harness according to claim 6, wherein: The automobile wiring harness production and assembly method comprises the following steps: Step 1: First, ensure that all power mechanisms are in normal working condition and start the entire equipment; wind wire harnesses of different models and specifications onto the wire reel of the wire feeding mechanism and place the connector on the conveyor table; Step 2: The second driver drives the wire drum to rotate, so that the wire harness body is automatically released from the wire drum. The wire harness body enters the wire feeding mechanism through the wire inlet hole, is guided by the first guide wheel and the second guide wheel, and is driven by the wire harness conveying roller to enter the wire outlet hole. Step 3: The conveyor belt transports the connector to the fixed position, and the electric cylinder drives the telescopic rod to extend and retract, so that the splint contacts and fixes the connector; Step 4: The second motor drives the second screw to rotate, causing the movable frame to move horizontally above the connector. The third driver drives the lifting rod to rotate, causing the wiring mechanism to descend to the connector position. The wiring mechanism fixes the wiring harness body to the connector and adjusts the length and position of the wiring harness as needed. When the wiring harness is arranged, the cutting mechanism cuts the excess wiring harness to ensure that the wiring harness length meets the requirements.
