[0022] The wire harness to be cut can be placed in the support 2 and transported forward. When the wire harness is transported to a certain length and is on the support platform 16, the cutting knife 15 fixed at the output end can be driven downward by starting the electric push rod 2 14 to cut the wire harness. At the same time, the cutting knife 15 can be inserted into the notch provided on the support platform 16 for cutting, so as to fully cut the wire harness and reduce damage to the cutting edge of the cutting knife 15.

[0023] Reference Figure 1-Figure 3 , through grooves 3 are opened on both sides of the inner wall of the support 2, and the bottom walls of the two through grooves 3 are rotatably connected to multiple transmission rollers 5. Multiple transmission rollers 5 on both sides are evenly distributed in the through grooves 3, and the tops of multiple transmission rollers 5 are rotatably connected to the top wall of the through groove 3. The outer peripheries of the tops of multiple transmission rollers 5 are fixedly connected to pulleys 6, and the outer peripheries of the pulleys 6 on both sides are engaged with transmission belts 7. The bottom ends of multiple pulleys 6 are fixedly connected to limit disks 8, and multiple limit disks 8 are arranged on the upper periphery of the transmission rollers 5. The sizes of multiple limit disks 8 are larger than the pulleys 6 and are located on the lower side of the transmission belt 7. A servo motor 4 is fixedly connected to both sides of the rear side of the top wall of the support 2. The output ends of the two servo motors 4 both pass through the inner wall of the through groove 3 and are fixedly connected to the top of the rear transmission roller 5; the abutment component, the abutment component is arranged on the upper side of the support 2, the abutment component is used to abut the wiring harness to increase the friction between the wiring harness and the transmission roller 5, the abutment component includes a connecting frame 9, the connecting frame 9 is fixedly connected to the middle of the two side walls of the support 2, and the middle of the top wall of the connecting frame 9 is fixedly connected to an electric push rod 10, the output end of the electric push rod 10 passes through the bottom wall of the connecting frame 9 and is fixedly connected to an abutment plate 11, the abutment plate 11 is parallel to the inner bottom wall of the support 2 and is in the same plane, and the inner wall of the abutment plate 11 is rotatably connected to multiple rollers 12.

[0024] The staff can place the wire harness to be cut in the support 2. Since the support 2 is V-shaped, the wire harness will be stuck in the bottom wall of the support 2 and contact the transmission rollers 5 on both sides. Then, starting the electric push rod 10 can drive the abutment plate 11 fixed at the output end to move downward and abut against the wire harness. Then, by starting the servo motor 4 on both sides, the transmission roller 5 fixed at the output end can be driven to rotate. When the transmission roller 5 rotates, it will drive the pulley 6 connected to the top to rotate. When one pulley 6 rotates, it can drive the transmission belt 7 to move and, under the action of the transmission belt 7, it can drive multiple meshing pulleys 6 to rotate at the same time, thereby driving multiple transmission rollers 5 to rotate at the same time, and then driving the wire harness in the support 2 to be transported forward. By setting a roller 12 in the abutment plate 11, the roller 12 can replace the abutment plate 11 with the wire harness, and the sliding friction is changed to rolling friction. Therefore, under the action of the roller 12, while ensuring normal abutment with the wire harness, the friction between the wire harness and the roller 12 can be reduced to ensure normal transportation of the wire harness.

[0025] Reference Figure 1-Figure 3, grooves 21 are provided on the front and rear parts of both sides of the support platform 16, the front wall of the support platform 16 is fixedly connected to a fixing frame 17, and the front wall of the fixing frame 17 is fixedly connected to a servo motor 2 18, the output end of the servo motor 2 18 passes through the fixing frame 17 and is fixedly connected to a gear 19, one side of the gear 19 is meshed with a gear 20, and the sides away from the gear 19 and the gear 2 20 are meshed with a gear 3 25, and the rear ends of the two gears 3 25 are fixedly connected to a connecting shaft 23, and the two connecting shafts 23 pass through the front and rear walls of the front and rear grooves 21, and the outer peripheries of the front and rear ends of the two connecting shafts 23 are fixedly connected to a clamping plate 24, and the two clamping plates 24 are both L-shaped plates, and a notch is provided on the clamping plate 24 on one side to match the clamping plate 24 on the other side, and the front and rear walls of multiple clamping plates 24 are fixedly connected to one end of a torsion spring 22, and the other ends of multiple torsion springs 22 are fixedly connected to the front and rear walls of the groove 21, and multiple torsion springs 22 are arranged on the outer periphery of the connecting shaft 23.

[0026] When the wire harness is delivered to the support table 16 to be cut, the servo motor 2 18 is started to drive the gear 19 fixed at the output end to rotate. When the gear 19 rotates, the gear 2 20 engaged on one side can be driven to rotate, so that the gear 19 and the gear 2 20 can rotate in the direction of approaching or moving away at the same time. When the gear 19 and the gear 2 20 rotate relative to each other, the two gears 3 25 can be driven to rotate relative to each other, thereby driving the connecting shaft 23 connected to the corresponding gear 3 25 and the clamping plate 24 connected to the connecting shaft 23 to rotate relative to each other. When the clamping plates 24 on both sides approach at the same time, the wire harness on the support table 16 can be clamped from the front and back sides to ensure stability when cutting the wire harness. When the clamping plates 24 approach at the same time, they will pull the torsion spring 22. Therefore, the servo motor 2 18 can be stopped after the cutting is completed. At this time, under the action of the torsion spring 22, the clamping plate 24 can be reset and the positioning of the wire harness can be canceled, so that the cut wire harness can be removed.

[0027] Working principle: During actual use, the staff can place the wire harness to be cut in the support 2, and then start the electric push rod 10 to drive the abutment plate 11 fixed at the output end to move downward and abut against the wire harness. By starting the servo motors 4 on both sides, the transmission roller 5 fixed at the output end can be driven to rotate. When the transmission roller 5 rotates, it will drive the pulley 6 connected to the top to rotate, and under the action of the transmission belt 7, it can drive multiple meshing pulleys 6 to rotate, thereby driving multiple transmission rollers 5 to rotate at the same time, and then driving the wire harness in the support 2 to be transported forward.

[0028] In addition, when the wire harness is transported to the support table 16 to be cut, by starting the servo motor 2 18, the gear 19 fixed at the output end can be driven to rotate. When the gear 19 rotates, it can drive the gear 2 20 engaged on one side. When the gear 19 and the gear 2 20 rotate relative to each other, the two gears 3 25 can be driven to rotate relative to each other, thereby driving the corresponding connected connecting shaft 23 and the clamping plate 24 connected to the connecting shaft 23 to rotate relative to each other, so that the clamping plates 24 on both sides can approach each other at the same time and clamp the wire harness to ensure stability when cutting the wire harness.

[0029] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention.
