[0024] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments.

When the combination of technical solutions is contradictory or cannot be implemented, it should be deemed that such a combination of technical solutions does not exist and is not within the scope of protection required by the present utility model.

[0027] Currently, the cutting of excess weaving mainly relies on manual trimming with scissors, but manual trimming of weaving is not only inefficient, but also has the problem of uneven length.

[0028] To this end, the utility model proposes a wire harness braiding and cutting mechanism, which is installed at the cutting station of the braiding machine. Figure 1 When the wire harness 7 passes through the assembly line and reaches the cutting station, the root of the braid 72 is fixed on the peripheral side of the wire core 71, and the free end of the braid 72 explodes and spreads outward.

[0029] Reference Figures 2 to 5An embodiment of the wire harness weaving and cutting mechanism includes a frame 1 and a punching assembly. A cutting cavity is formed in the frame 1. The frame 1 has a first panel 11 facing the wire harness 7. A feed channel 113 is provided on the first panel 11. The feed channel 113 separates the first panel 11 into a first baffle 111 and a second baffle 112. The wire harness 7 passes through the feed channel 113 and enters the cutting cavity. The braid 72 contacts and fits with the inner surface of the first panel 11. The punching assembly includes a first punching piece 21 and a second punching piece 23. The first punching piece 21 and the second punching piece 23 can be installed in the cutting cavity so as to be movable forward and backward. The first punching piece 21 is arranged opposite to the first baffle 111, and the second punching piece 23 is arranged opposite to the second baffle 112. When the weaving 72 is in contact with the inner surface of the first baffle 111, the first punching piece 21 punches toward the first baffle 111 to cut the weaving 72. When the weaving 72 is in contact with the inner surface of the second baffle 112, the second punching piece 23 punches forward to cut the remaining weaving 72.

[0030] The frame 1 is surrounded by six panels, and a cutting cavity is formed in the frame 1. The two panels opposite to each other are defined as a first panel 11 and a second panel. The first panel 11 is provided with a feed channel 113 which is arranged through in the up-down direction to separate the first panel 11 into a first baffle 111 and a second baffle 112, and the width of the feed channel 113 is greater than the diameter of the longest braid 72. The cutting cavity is provided with a first punching piece 21 and a second punching piece 23 which can move forward and backward. The first punching piece 21 is arranged opposite to the first baffle 111, and the second punching piece 23 is arranged opposite to the second baffle 112. The first punching piece 21 is used to cut half of the braid 72, and the second punching piece 23 is used to cut the other half of the braid 72, thereby completing the ring cutting of the entire braid 72.

[0031] Specifically, the working steps of the wire harness weaving and cutting mechanism are as follows: insert the weaving 72 into the cutting cavity through the feed channel 113, then the wire harness 7 moves toward the first panel 11, and the edge of the wire harness 7 abuts against the edge of the first panel 11, then the wire harness 7 moves backward so that part of the weaving 72 contacts and fits with the inner surface of the first baffle 111, at this time, the first punching piece 21 punches toward the first baffle 111 to complete the cutting of this part of the weaving 72; then, the wire harness 7 moves forward, and after the weaving 72 detaches from the first baffle 111, the wire harness 7 moves toward the second panel, and the edge of the wire harness 7 abuts against the edge of the second panel, then, the wire harness 7 moves backward so that the remaining part of the weaving 72 contacts and fits with the inner surface of the second baffle 112, at this time, the second punching piece 23 punches toward the second baffle 112 to complete the cutting of this part of the weaving 72.

[0032] The movement of the wire harness 7 can be done manually. Of course, in order to improve production efficiency, a transverse movement mechanism can be set to drive the wire harness 7 to move forward, backward, left and right, or to drive the frame 1 to move forward, backward, left and right, so that the wire harness 7 and the frame 1 can move relative to each other.

[0033] For example, refer to Figure 2 or Figure 5 The embodiment of the wire harness weaving and cutting mechanism may further include an X-axis lateral movement mechanism 3 and a Y-axis lateral movement mechanism 4. The Y-axis lateral movement mechanism 4 is connected to the X-axis lateral movement mechanism 3 and moves left and right under the drive of the X-axis lateral movement mechanism 3. The frame 1 is connected to the Y-axis lateral movement mechanism 4 and can move forward and backward under the drive of the Y-axis lateral movement mechanism 4. Thus, the X-axis lateral movement mechanism 3 can drive the Y-axis lateral movement mechanism 4 and the frame 1 to move in the left and right direction, and the Y-axis lateral movement mechanism 4 can drive the frame 1 to move in the front and back direction, so that the frame 1 and the wire harness 7 can move forward and backward and left and right.

[0034] In summary, the wire harness braiding and cutting mechanism arranges the first punching piece 21 and the second punching piece 23 in the frame 1, realizes the circular cutting of the braiding 72 through the first punching piece 21 and the second punching piece 23, and cuts the braiding 72 in a mechanized manner. Compared with manual cutting, the production efficiency and cutting accuracy are greatly improved.

[0035] Reference Figure 3 A first limiting opening 1111 is formed on the edge of the first baffle plate 111 facing the feed channel 113, a second limiting opening 1121 is formed on the edge of the second baffle plate 112 facing the feed channel 113 and is arranged opposite to the first limiting opening 1111, the first punching member 21 is arranged opposite to the first limiting opening 1111, and the second punching member 23 is arranged opposite to the second limiting opening 1121. The first limiting opening 1111 and the second limiting opening 1121 are used to position the wiring harness 7. When the wiring harness 7 moves toward the first baffle 111 and is clamped in the first limiting opening 1111, part of the braiding 72 is in contact with and fits against the inner surface of the first baffle 111. At this time, the first punching piece 21 punches toward the first baffle 111 to complete the cutting of the part of the braiding 72. When the wiring harness 7 moves toward the second baffle 112 and is clamped in the second limiting opening 1121, the rest of the braiding 72 is in contact with and fits against the inner surface of the second baffle 112. At this time, the second punching piece 23 punches toward the second baffle 112 to complete the cutting of the part of the braiding 72.

[0036] In one embodiment, the first limiting opening 1111 and the second limiting opening 1121 are both semicircular, and the diameters of the first limiting opening 1111 and the second limiting opening 1121 are equal to the diameters of the wiring harness 7, that is, the first limiting opening 1111 and the second limiting opening 1121 are set in half. Therefore, when the wiring harness 7 is clamped in the first limiting opening 1111, half of the braid 72 is in contact with the inner surface of the first baffle 111, and when the wiring harness 7 is clamped in the second limiting opening 1121, the other half of the braid 72 is in contact with the inner surface of the second baffle 112. The first punching piece 21 is used to punch half of the braid 72, and the second punching piece 23 is used to punch the other half of the braid 72, thereby completing the circular cutting of the entire circular braid 72.

[0037] Further, see Figure 4 A first stopper 1112 is convexly provided on one side of the first baffle plate 111 facing the cutting cavity, and a second stopper 1122 is convexly provided on one side of the second baffle plate 112 facing the cutting cavity. The first stopper 1112 and the second stopper 1122 are both in the shape of a half-circular arc. The first stopper 1112 is arranged around the first stopper opening 1111, and the second stopper 1122 is arranged around the second stopper opening 1121. The widths of the first stopper 1112 and the second stopper 1122 are equal, and the widths of the first stopper 1112 and the second stopper 1122 are the reserved lengths of the braid 72. When the wiring harness 7 is clamped in the first limiting opening 1111, the braiding 72 of the wiring harness 7 is in contact with and fits with the first limiting block 1112, and the first punching piece 21 punches toward the first limiting block 1112 to cut the braiding 72 that protrudes from the edge of the first limiting block 1112; when the wiring harness 7 is clamped in the second limiting opening 1121, the braiding 72 of the wiring harness 7 is in contact with and fits with the second limiting block 1122, and the second punching piece 23 punches toward the second limiting block 1122 to cut the braiding 72 that protrudes from the edge of the second limiting block 1122.

[0038] Among them, refer to Figure 3 The first punching member 21 includes a first base 211 and a first punching block 212 vertically arranged with the first base 211. The first punching block 212 is provided with a first punching hole 213 along the axial direction of the wire harness 7. The diameter of the first punching hole 213 is consistent with the diameter of the first stop block 1112. When the first punching member 21 punches toward the first stop block 1112, the first stop block 1112 is embedded in the first punching hole 213, and the outer wall of the first stop block 1112 is sheared with the side wall of the first punching hole 213, thereby cutting off the braid 72 protruding from the edge of the first stop block 1112.

[0039] Similarly, the second punching member 23 includes a second base 231 and a second punching block 232 vertically arranged with respect to the second base 231. The second punching block 232 is provided with a second punching hole 233 along the axial direction of the wiring harness 7. The diameter of the second punching hole 233 is consistent with the diameter of the second stop block 1122. When the second punching member 23 punches toward the second stop block 1122, the second stop block 1122 is embedded in the second punching hole 233, and the outer wall of the second stop block 1122 is sheared with the side wall of the second punching hole 233, thereby cutting off the braid 72 protruding from the edge of the second stop block 1122.

The first cylinder assembly 22 includes a first cylinder barrel 221, a first piston (not shown), a first piston rod 222 and a first push block 223.

One end of the second piston rod 242 is connected to the second piston, and the other end of the second piston rod 242 is connected to the second push block 243. The second punching piece 23 moves back and forth under the drive of the second cylinder assembly 24.

[0043] It is not difficult to understand that the cut braided scraps are easily adhered to the wire harness 7. To clean the scraps, refer to Figure 5Some embodiments of the wire harness weaving and cutting mechanism also include a blowing module 5 and a debris bin 6.
