As a key component connecting automotive electronic systems, the quality of wiring harnesses directly affects the overall performance and safety of the vehicle. Traditionally, the production process of wiring harnesses involves a large amount of manual operation, including cutting, soldering, and wiring steps. This is not only inefficient but also prone to human error, leading to unstable product quality.

[0031] like Figures 1-7 As shown in the figure, this utility model embodiment provides a fully automatic wire harness crimping and cutting machine.

[0032] A fully automatic wire harness pressing and cutting machine includes a machine base 1, a roll feeding mechanism 2, a pressing and welding mechanism 3, a cutting mechanism 4, and a wire pulling mechanism 5. The pressing and welding mechanism 3, the cutting mechanism 4, and the wire pulling mechanism 5 are sequentially arranged on the machine base 1. The roll feeding mechanism 2 is located outside the cutting mechanism 4. The wire pulling mechanism 5 includes a wire pulling frame 6, a lateral displacement mechanism 7, and a pneumatic gripper 8. The wire pulling frame 6 is located on the machine base 1, the lateral displacement mechanism 7 is located on the top of the wire pulling frame 6, and the pneumatic gripper 8 is located at the output end of the lateral displacement mechanism 7.

[0033] This invention uses a coil feeding mechanism 2 to feed the wire harness, followed by a pressing and welding mechanism 3 to perform intermittent pressing and welding of the wire harness. During cutting, the cutting mechanism 4 cuts the middle section of the pressed and welded portion of the wire harness, while simultaneously performing pressing and welding on the front section. After cutting, a pneumatic gripper 8 picks up the cut pressed and welded portion of the wire harness and pulls it to the next pressing and welding position for further cutting. This wire pulling method offers high precision in wire harness transportation, reducing the risk of misalignment when handling thick materials. The precise positioning system and stable actuator ensure consistency and accuracy in every operation, guaranteeing high-precision pressing and cutting, and meeting the modern manufacturing industry's pursuit of efficient and precise production.
