[0037] As Figures 1-8 shown, an embodiment of the first aspect of the present invention provides a fully automatic wire harness square pressing and cutting machine.

[0038] A fully automatic wire harness square pressing and cutting machine includes a machine table 1, a coil feeding mechanism 2, a square pressing and welding mechanism 3, a cutting mechanism 4, and a wire pulling mechanism 5. The square pressing and welding mechanism 3, the cutting mechanism 4, and the wire pulling mechanism 5 are sequentially arranged on the machine table 1. The coil feeding mechanism 2 is arranged 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 arranged on the machine table 1. The lateral displacement mechanism 7 is arranged on the top of the wire pulling frame 6. The pneumatic gripper 8 is arranged at the output end of the lateral displacement mechanism 7.

[0039] In the present invention, the coil feeding mechanism 2 is used for feeding. Subsequently, the square pressing and welding mechanism 3 performs interval square pressing and welding on the wire harness. When the cutting mechanism 4 cuts, it cuts the middle part of the square pressing and welding part of the wire harness, and at the same time, square pressing and welding are performed on the front section during cutting. After cutting, the pneumatic gripper 8 grabs the square pressing and welding part of the cut wire harness and pulls the wire harness to the next square pressing and welding part for cutting. This wire pulling method has high transportation accuracy for the wire harness, can reduce the problem of deviation when processing thick materials, and the precise positioning system and stable execution mechanism ensure the consistency and accuracy of each operation, guarantee high-precision square pressing and cutting, and meet the pursuit of efficient and precise production in modern manufacturing.

[0040] A fully automatic wire harness square pressing and cutting machine according to this embodiment, the cutting mechanism 4 includes a first cutting vertical frame 9, a second cutting vertical frame 10, a first lifting drive mechanism 11 and a second lifting drive mechanism 12.

It can be understood that the first lifting drive mechanism 11 drives the overall lifting of the second cutting vertical frame 10, that is, the lower knife seat 14 will also lift upward, and the second lifting drive mechanism 12 then drives the upper knife seat 15 to descend for cutting, which can achieve simultaneous force on the upper and lower parts and reduce the problem of deviation when cutting thick materials.
