A vertical guide rail 17 is provided on the upper side of the third base plate 16, and the upper tool holder 2 and the lower tool holder 3 slide with the vertical guide rail 17 through the first vertical slider 18 and the second vertical slider 19 respectively.

[0045] Specifically, the second vertical drive motor 23 drives the second vertical screw rod 24 to rotate, and drives the second vertical nut 25 to move vertically through the threaded engagement between the second vertical screw rod 24 and the second vertical nut 25 .

Not only can the position of the cable be accurately corrected by the action of the first cable management groove 28 and the second cable management groove 29 to overcome the error of the cable position, but also the first cable management component 26 and the second cable management component 27 can be moved back and forth by moving the X-direction moving mechanism 4 when necessary, thereby enhancing the cable management effect.

[0050] Furthermore, the sides of the first wire-managing component 26 and the second wire-managing component 27 that are away from each other are connected to the upper knife holder 2 and the lower knife holder 3 respectively through their own springs. In the natural state, the distance between the first wire-managing component 26 and the second wire-managing component 27 is smaller than the distance between the two contour knives 37. When working, the first wire-managing component 26 and the second wire-managing component 27 first contact the cable through the first wire-managing groove 28 and the second wire-managing groove 29, and then compress the spring, and then the two contour knives 37 contact the cable to cut the cable.

[0055] Specifically, the control unit can control the X-direction moving mechanism 4, the Y-direction moving mechanism 5, the first vertical driving structure and the second vertical driving structure according to the measurement results of the X-direction ranging component 30, the Y-direction ranging component 31 and the Z-direction ranging component 32, so that when the wire harness is cut, each cable can be automatically cut in sequence under the control of the control unit, and can be automatically cut according to the cutting length requirements of each cable.

[0056] In this embodiment, the cable includes two wire cores arranged side by side, and aluminum foil is wrapped around the outside of the two wire cores. Figure 7 and Figure 8 As shown, the first cable management groove 28 and the second cable management groove 29 respectively include an arc-shaped groove, which matches the overall shape of the cable; the cutting edges of the two profiling knives 37 include two arc-shaped cutting edge grooves 38, and a protrusion is formed between the two cutting edge grooves 38. The shape setting of the profiling knife 37 can well avoid the ground wire and avoid damage to the insulation layer and the ground wire; a longitudinal cutting knife 39 is provided on the lower side of the upper knife holder 2, and a long strip of pad 40 is provided on the upper side of the lower knife holder 3 at the corresponding position of the longitudinal cutting knife 39, which is used to pad the position between the two wire cores and cooperate with the longitudinal cutting knife 39 to cut the cable longitudinally and cut the Mylar film of the cable to avoid difficulty and poor stripping caused by the Mylar film being wrapped too tightly.
