DETAILED DESCRIPTION

[0034] In order to enable those skilled in the art to better understand the scheme of the present invention, the technical scheme in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work should fall within the scope of protection of the present invention.

[0035] The prior art often uses manual methods to select the bottom line in the wire harness, which has low work efficiency. However, the present invention provides a wire crimping device for a multi-core wire harness, which can disassemble the wire harness to facilitate the selection and removal of the wire harness, thereby improving production efficiency and reducing production costs.

[0036] like Figure 1-Figure 7 A wire crimping device for a multi-core wire harness is shown, comprising a wire crimping base 1, a wire crimping module 2 and a limit module 3 arranged on the wire crimping base 1, the limit module 3 being used to clamp the wire harness to be processed and keep one end of the wire harness to be processed stationary, the wire crimping module 2 comprising a first sliding component 21 installed on the wire crimping base 1, and a wire twisting component 22 slidably connected to the first sliding component 21, the first sliding component 21 can drive the wire twisting component 22 to press the wire harness toward the limit module 3 until the wire harness is pressed into a lantern shape, the wire twisting component 22 comprises an electric finger 222, a first clamping jaw component 221 installed at one end of the electric finger 222 and a rotating motor 223 at the other end, the rotating motor 223 being used to drive the first clamping jaw component 221 to twist the wire harness.

[0037] like Figure 7As shown, the twisting and pressing wire harness base 1 can be a square support, or it can be composed of two support columns arranged between the upper panel and the lower panel, and the upper panel is used to install the limit module 3 and the twisting assembly 22. The limit module 3 is mainly used to fix the wire harness, because when processing the wire harness, the wire harness needs to be twisted and pressed into a lantern shape, and one end of the wire harness to be processed needs to be kept stationary, and the stationary mentioned here means neither rotating nor moving. When the wire twisting assembly 22 twists the wire harness, one end of the wire harness needs to remain stationary, so the limit module 3 is used to clamp the critical position of the non-processing end and the processing end of the wire harness to be processed, and then the wire twisting assembly 22 starts to twist the wire harness. The wire twisting assembly 22 performs the first twist according to the winding direction of the wire harness. If the wire harness is wound clockwise, the wire harness is twisted clockwise, that is, the original winding direction of the wire harness is pre-tightened, because if the wire harness is not pre-tightened, the wire harness is directly twisted counterclockwise. When the wire harness already shows signs of unraveling, it is twisted counterclockwise so that the wire harness is twisted into a wire harness wound in another direction again. The wire harness is not opened, so the wire harness needs to be pre-tightened first, and then the wire harness is twisted in the opposite direction to loosen the wire harness. The first clamping jaw assembly 221 in the wire twisting assembly 22 can complete the pre-tightening and loosening of the wire harness.

[0038] In a preferred embodiment, in order to better complete the pre-tightening of the wire harness in the original winding direction, the twisting assembly 22 also includes a second clamping jaw assembly 224, and the second clamping jaw assembly 224 includes an upper clamping block 2241, a lower clamping block 2242, and a second power assembly 2243 that drives the upper clamping block 2241 and the lower clamping block 2242 to close and clamp the wire harness. When the upper clamping block 2241 and the lower clamping block 2242 are closed, a columnar second cavity for clamping the wire harness is formed. The first clamping assembly 221 includes a left clamping block 2211 and a right clamping block 2212, and the left clamping block 2211 and the right clamping block 2212 also form a first cavity for clamping the wire harness, the inner wall of the first cavity is not smooth and the inner wall of the second cavity is not smooth, but the inner wall of the first cavity is rougher than the inner wall of the second cavity, that is, the second cavity is more suitable for pre-tightening the wire harness. If only the first clamping jaw assembly 221 is used to pre-tighten the wiring harness, the wiring harness may be too forceful when rotating, and the wiring harness may be easily damaged when rotating in the opposite direction. Therefore, the second clamping jaw assembly 224 in the twisting assembly 22 is required to pre-tighten the wiring harness in the original direction. The second power assembly 2243 is a second clamping jaw assembly 224 cylinder, and the second clamping jaw assembly 224 cylinder drives the upper clamping block 2241 and the lower clamping block 2242 to clamp the wiring harness. The clamping method is: when the upper clamping block 2241 and the lower clamping block 2242 are closed, a cylindrical second cavity will be formed. The diameter of this second cavity is slightly smaller than the wiring harness. The inner wall of the second cavity is smoother than the inner wall of the first cavity, so that the clamping force of the wiring harness is not as strong as the first clamping jaw assembly 221, so the damage to the wiring harness caused by repeated twisting will not be very large. In order to enhance the effect of pre-tightening the wiring harness, a thread or a plurality of protrusions that enhance friction are provided on the inner wall of the second cavity to increase the friction between the inner wall of the second cavity and the wiring harness. The first clamping jaw assembly 221 includes a left clamping block 2211 and a right clamping block 2212, and a first power assembly 2213 that drives the left clamping block 2211 and the right clamping block 2212 to clamp the wire harness. The first power assembly 2213 is a linear pneumatic finger, and the linear pneumatic finger includes two fingers for driving the left clamping block 2211 and the right clamping block 2212 to open and close. The left clamping block 2211 and the right clamping block 2212 are closed to clamp the wire harness.

[0039] The second power assembly 2243 is a cylinder of the second clamp assembly 224 installed on the side wall of the electric finger 222. Since the second clamp assembly 224 clamps the wire harness in the up and down directions, in order to facilitate the installation of the first clamp assembly 221, the clamping blocks of the second clamp assembly 224 are arranged on the left and right sides, and a cavity is formed when the left clamping block 2211 and the right clamping block 2212 are closed, which is the first cavity. The diameter of the cavity is much smaller than the diameter of the second cavity, and the wire harness can be fully clamped, and the force on the wire harness will be greater.

[0040] like Figure 6As shown, in a preferred embodiment, the limiting module 3 includes a bracket arranged on the twisting and pressing harness base 1, a transmission mechanism 32 installed on the bracket, and a third clamping jaw assembly 31 installed on the transmission mechanism 32 and driven to open and close by the transmission mechanism 32. The third clamping jaw assembly 31 includes a left clamping jaw 311 and a right clamping jaw 312; the transmission mechanism 32 includes a power source, a fixed block 321, a first transmission rod 323, a second transmission rod 324, a vertical slider, a vertical slide rail 327, a third transmission rod 325 and a fourth transmission rod 326; wherein a power rod 322 extends from the lower part of the fixed block 321, one end of the first transmission rod 323 and the second transmission rod 324 are respectively connected to the power rod 322, the other ends of the first transmission rod 323 and the second transmission rod 324 are respectively hinged to one end of the third transmission rod 325 and the fourth transmission rod 326, the other ends of the third transmission rod 325 and the fourth transmission rod 326 are respectively hinged to the vertical slider, the vertical slider slides on the vertical slide rail and is fixedly connected to the power source.

[0041] The specific structure of the limiting module 3 is: the power source is a cylinder or other linear motion structure on which a linear slide rail is arranged as a vertical slide rail. For example, the power source is a vertically arranged cylinder, and a slide groove is arranged on the surface of the cylinder as a vertical slide rail. The fixed block 321 is fixed to the twist and press harness base 1 through a bracket. The vertical slide rail can be driven by the power source through the structure of the slide rail and the cooperation of the fixed block to complete the up and down sliding of the vertical slide rail. A power rod 322 extends out of the fixed block in order to install the first transmission rod 323 and the second power rod 324. As shown in the figure, the right end of the power rod 322 is hinged to one end of the first transmission rod 323, and the left end of the power rod 322 is hinged to one end of the second transmission rod 324; then, one end of the fourth transmission rod 326 is hinged to the end of the first transmission rod 323 away from the power rod 322, and one end of the second transmission rod 342 away from the power rod 322 is hinged to one end of the third transmission rod 325, and one end of the fourth transmission rod 326 away from the first transmission rod 323 is hinged to the vertical slider. One end of 325 away from the second transmission rod 324 is hinged to the vertical slider, the fourth transmission rod 326 coincides with the hinge point of the third transmission rod 325 and the vertical slide rail, and the vertical slide rail is hidden between the fixed block 321 and the vertical slide rail. When the wiring harness is clamped, the first transmission rod 323, the second transmission rod 324, the third transmission rod 325, and the fourth transmission rod 326 form an isosceles triangle with the first transmission rod 323 and the second transmission rod 324 as the base; when the wiring harness is released, the first transmission rod 323, the second transmission rod 324, the third transmission rod 325, and the fourth transmission rod 326 form a quadrilateral.

[0042] The first sliding assembly 21 includes a base slider 211 sleeved on the wire twisting assembly 22 , a slider rail 212 slidably connected to the base slider 211 , and a first sliding assembly cylinder 213 driving the base slider 211 to move back and forth linearly on the slider rail 212 .

[0043] The device also includes a harness fixing assembly 4 for installing the harness to be processed, the harness fixing assembly 4 includes a base 41 and a clip arranged on the base 41 for fixing the harness, and the harness fixing assembly 4 can install at least two harnesses.

[0044] The overall operation of the device is as follows: the wire harness is fixed on the wire harness fixing component 4. Since the wire harness fixing component 4 has the same height as the component or module of the overall processed wire harness, the third clamping jaw component 31 in the limiting module 3 tightens the wire harness, and the rotating motor 223 rotates along the winding direction of the wire harness to pre-tighten the wire harness. Then the second clamping jaw component 224 releases the wire harness, and the first clamping jaw component clamps the wire harness. The rotating motor 223 starts to rotate in the other direction to gradually loosen the wound wire harness. At the same time, the first sliding assembly cylinder 213 on the first sliding assembly 21 drives the first clamping jaw component 221 to clamp the wire harness and gradually press it toward the third clamping jaw component 31 until the wire harness is pressed into a lantern shape.

[0045] A wire crimping method for a multi-core wire harness comprises the following steps:

[0046] S1, fixing the processed wire harness on the wire harness fixing component 4;

[0047] S2, driving the limit module 3 to clamp one end of the processing wiring harness;

[0048] S3, driving the wire twisting assembly 22 to clamp the other end of the wire harness to be processed;

[0049] S4, driving the rotating motor 223 to drive the wire twisting assembly 22 to twist the wire harness, and at the same time the first sliding assembly 21 drives the wire twisting assembly 22 to press the wire harness toward the limiting module 3 until the wire harness is pressed into a lantern shape.

[0050] The steps for twisting the wire harness to compress the wire harness into a lantern shape are as follows:

[0051] S401, driving the second clamping jaw assembly 224 in the wire twisting assembly 22 to clamp the wire harness;

[0052] S402, driving the rotating motor 223 to drive the second clamping jaw assembly 224 to twist the wire harness, wherein the twisting direction is the winding direction of the wires in the wire harness;

[0053] S403, driving the second clamping jaw assembly 224 to release the wire harness, and then driving the first clamping jaw assembly 221 in the wire twisting assembly 22 to clamp the wire harness;

[0054] S404, driving the rotating motor 223 to rotate in the opposite direction, and at the same time driving the first sliding assembly 21 to drive the first clamping claw assembly 221 to press the wire harness toward the limiting module 3 until the wire harness is pressed into a lantern shape.

[0055] The device sets the twisting component 22 and the limit module 3 to cooperate in twisting the wire harness, making the wire harness loose, which is convenient for selecting the ground wire in the wire harness. The limit module 3 clamps the wire harness to keep the non-processed end of the wire harness stationary. The twisting component 22 can pre-tighten the wire harness in the winding direction of the wire harness and then twist the wire harness in the reverse direction to make the wire harness loose, which is more conducive to selecting the target wire in the wire harness and realizing automated production.

[0056] The above embodiments are not limited to the technical solutions of the embodiments themselves, and the embodiments can be combined with each other to form new embodiments. The above embodiments are only used to illustrate the technical solutions of the present invention and are not intended to limit them. Any modification or equivalent replacement that does not deviate from the spirit and scope of the present invention shall be included in the scope of the technical solutions of the present invention.
