[0024] When in use, the wire harness is passed between the winding roller 210 and the pressing roller 310, and the end of the wire harness is fixed on the winding roller 210. By manipulating the first rotating driving member 220, the first rotating driving member 220 can drive the winding roller 210 to rotate, so that the wire harness can be wound up. During the winding process, as the diameter of the coil increases, the coil will push the pressing roller 310 to move radially along the winding roller 210. At this time, the first elastic member 320 is in a compressed state and accumulates compressed elastic potential energy. The first elastic member 320 will push the pressing roller 310 close to the winding roller 210, so that the pressing roller 310 presses the coil to avoid the situation where the coil becomes looser due to the gradual decrease in winding tension. Combined with the increase in output torque, the control effect of the tightness of the coil can be improved.

[0025] As a preferred embodiment, please refer to Figure 1 One end of the winding roller 210 is rotatably disposed on the bracket 100 so that the output end of the first rotating driving member 220 is rotatably connected to one end of the winding roller 210 .

[0026] As a preferred embodiment, please refer to Figure 1 The first elastic member 320 is a spring, which can accumulate compressive elastic potential energy when subjected to pressure and act in the reverse direction on the coil.

[0027] As a preferred embodiment, please refer to Figure 1 The pressing assembly 300 also includes a movable frame 330, which is slidably disposed on the bracket 100 and can move along the radial direction of the winding roller 210 to approach or move away from the winding roller 210. One end of the pressing roller 310 is rotatably disposed on the movable frame 330, and one end of the first elastic member 320 is fixedly connected to the movable frame 330, so that the pressing roller 310 can be supported by the movable frame 330.

[0028] As a preferred embodiment, please refer to Figure 1 The bracket 100 is provided with a slide groove 110 , and the slide groove 110 extends along the radial direction of the winding roller 210 . The movable frame 330 is slidably disposed on the slide groove 110 , and the movement of the movable frame 330 can be guided by the slide groove 110 .

[0029] As a preferred embodiment, please refer to Figure 1The pressing and rolling assembly 300 also includes a second rotating driving member 340, which is fixedly mounted on the movable frame 330. The output end of the second rotating driving member 340 is fixedly connected to one end of the pressing and rolling roller 310, and is used to drive the pressing and rolling roller 310 to rotate, so that the pressing and rolling roller 310 and the winding roller 210 have the same rotation speed and opposite direction. By manipulating the second rotating driving member 340, the second rotating driving member 340 can drive the pressing and rolling roller 310 to rotate, and ensure that the rotation speed of the pressing and rolling roller 310 is the same as the rotation speed of the winding roller 210, and the direction is opposite to that of the winding roller 210, which can assist the wire harness to pass between the winding roller 210 and the pressing and rolling roller 310.

[0030] As a preferred embodiment, please refer to Figure 1 The pressing roller 310 is arranged directly above the winding roller 210 , and a space for installing other components can be reserved below the winding roller 210 .

[0031] As a preferred embodiment, please refer to Figure 1 and Figure 2 The wire harness winding mechanism also includes a limiting component 400, and the limiting component 400 has a mounting portion 410 and a limiting portion 420. One end of the mounting portion 410 is fixedly connected to the movable frame 330, and the limiting portion 420 is arranged at the other end of the pressing roller 310. One end of the limiting portion 420 is rotatably connected to the other end of the mounting portion 410. The other end of the limiting portion 420 can reach or leave the other end of the winding roller 210. When the other end of the limiting portion 420 reaches the other end of the winding roller 210, it abuts against the end of the coiled material on the winding roller 210, and the coiled material on the winding roller 210 can be limited so that the coiled material can be wound on the winding roller 210. When the other end of the part 420 leaves the other end of the winding roller 210, the coil on the winding roller 210 can be removed. Since the coil is generally limited by setting a limit disk at the end of the winding roller 210, the limit disk is detachably fixed to the winding roller 210 by screws. Tools are required when disassembling and assembling the limit disk, and the disassembly and assembly of the limit disk is troublesome, resulting in low winding efficiency of the wire harness. The limiting part 420 is used to limit the coil on the winding roller 210. There is no need to disassemble and assemble the limiting part 420. Only the limiting part 420 needs to be rotated to make the limiting part 420 reach the other end of the winding roller 210 or move away from the other end of the winding roller 210.

[0032] As a preferred embodiment, please refer to Figure 2The mounting portion 410 is a mounting rod 411 , and the mounting rod 411 is disposed on the side of the pressing roller 310 along the length direction of the pressing roller 310 , and the length of the mounting rod 411 is equal to the length of the pressing roller 310 .

[0033] As a preferred embodiment, please refer to Figure 2 The limiting portion 420 includes a rotating shaft 421, two limiting rods 422 and a second elastic member 423. One end of the rotating shaft 421 is rotatably arranged on the other end of the mounting rod 411. One ends of the two limiting rods 422 are fixedly connected to the other end of the rotating shaft 421. A V-shaped structure is formed between the two limiting rods 422. One end of the second elastic member 423 is fixedly connected to the other end of the mounting rod 411. The other end of the second elastic member 423 is fixedly connected to one end of the two limiting rods 422, so that the other ends of the two limiting rods 422 are located on the winding roller 2 10, the other end of the two limit rods 422 can improve the contact strength with the other end of the coiled material. When the other ends of the two limit rods 422 are both located at the other end of the winding roller 210 and abut against the end of the coiled material on the winding roller 210, the coiled material on the winding roller 210 can be limited so that the coiled material can be wound on the winding roller 210. When the winding is completed, the other ends of the two limit rods 422 can be moved away from the other end of the winding roller 210 by rotating the two limit rods 422. At this time, the coiled material on the winding roller 210 can be removed.

[0034] As a preferred embodiment, please refer to Figure 2 The second elastic member 423 is a torsion spring, which is sleeved on the rotating shaft 421. When the other end of the two limit rods 422 rotates from one end of the winding roller 210 to other positions, the torsion spring will accumulate tensile elastic potential energy. When the external force acting on the two limit rods 422 disappears, the torsion spring will stretch the two limit rods 422 to reset the two limit rods 422.

[0035] As a preferred embodiment, please refer to Figure 2 The rolling assembly 300 also includes a slider 350, which is slidably disposed in the slide groove 110 and fixedly connected to the movable frame 330. One end of the mounting rod 411 is fixedly connected to the slider 350. The cooperation between the slider 350 and the slide groove 110 can guide the movement of the movable frame 330.

[0036] In order to better understand the present invention, the following Figure 1 - Figure 2 The working principle of the technical solution of the utility model is described in detail:

[0037] When in use, the wire harness is passed between the winding roller 210 and the pressing roller 310, and the end of the wire harness is fixed on the winding roller 210. By manipulating the first rotating drive member 220, the first rotating drive member 220 can drive the winding roller 210 to rotate, so that the wire harness can be wound. In the process of the winding roller winding the wire harness, the other ends of the two limiting rods 422 are located at the other end of the winding roller 210 and abut against the end of the coiled material on the winding roller 210, so that the coiled material on the winding roller 210 can be limited so that the coiled material can be wound on the winding roller 210. During the winding process, as the diameter of the coiled material increases, the coil The material will push the pressing roller 310 to move radially along the winding roller 210. At this time, the first elastic member 320 is in a compressed state and accumulates compressed elastic potential energy. The first elastic member 320 will push the pressing roller 310 to approach the winding roller 210, so that the pressing roller 310 presses the coiled material to avoid the situation where the coiled material becomes looser due to the gradual decrease in winding tension. Combined with the increase in output torque, the control effect on the tightness of the coiled material can be improved. When the winding is completed, the other ends of the two limiting rods 422 can be moved away from the other end of the winding roller 210 by rotating the two limiting rods 422. At this time, the coiled material on the winding roller 210 can be removed.

[0038] The utility model provides a wire harness winding mechanism with the following beneficial effects:

[0039] (1) When the other ends of the two limit rods 422 rotate from one end of the winding roller 210 to another position, the torsion spring will accumulate tensile elastic potential energy. When the external force acting on the two limit rods 422 disappears, the torsion spring will stretch the two limit rods 422 to reset the two limit rods 422. When the winding roller 210 winds up the wire harness, the limit rods 422 abut against the end of the coil, thereby improving the abutment strength between the other ends of the two limit rods 422 and the coil;

[0040] (2) Since the coil is generally limited by setting a limit disk at the end of the winding roller 210, and the limit disk is detachably fixed to the winding roller 210 by screws, tools are required when disassembling and assembling the limit disk, which is troublesome to disassemble and assemble, resulting in low winding efficiency of the wire harness. The limit part 420 is used to limit the coil on the winding roller 210. There is no need to disassemble and assemble the limit part 420. Only the two limit rods 422 need to be rotated to make the other ends of the two limit rods 422 reach the other end of the winding roller 210 or move away from the other end of the winding roller 210, which is very convenient.

[0041] (3) The first elastic member 320 pushes the pressing roller 310 to approach the winding roller 210, so that the pressing roller 310 presses the coiled material, thereby preventing the coiled material from becoming looser due to the gradual decrease in winding tension. Combined with the increase in output torque, the control effect on the tightness of the coiled material can be improved.

[0042] The specific implementation methods of the utility model described above do not constitute a limitation on the protection scope of the utility model. Any other corresponding changes and modifications made according to the technical concept of the utility model should be included in the protection scope of the claims of the utility model.
