[0026] To make the technical problem to be solved, the technical solution and the beneficial effects of this utility model clearer and more understandable, the following description is provided in conjunction with the appendix. Figure 1-9 The present invention will be further described in detail below with reference to the embodiments. It should be understood that the specific embodiments described herein are only for explaining the present invention and are not intended to limit the present invention.

[0027] Reference Figure 1A wire harness coating machine includes a frame 1, a translation module 2, a support plate 3, two tape holders 4, a drive mechanism 5, and two pairs of fixing components 6. The fixing components 6 secure the ends of the wire harness, fixing the wire harness to the same pair of fixing components 6. The translation module 2 is horizontally mounted on the frame 1, and the support plate 3 is fixed to the translation module 2. The two tape holders 4 are vertically fixed to the support plate 3 and are parallel to each other. Two pairs of mounting plates 11 are vertically fixed on the frame 1, and each fixing component 6 is rotatably mounted on the mounting plate 11. For this purpose, a rotating rod 7 is horizontally fixed on one side of each fixing component 6, and the rotating rod 7 is rotatably connected to the mounting plate 11. The fixing components 6 are arranged in pairs facing each other, and the drive mechanism 5 drives each fixing component 6 to rotate; the two ends of the wire harness are respectively fixedly mounted on the fixing components 6.

[0028] Reference Figure 2 Each tape holder 4 is equipped with a material roller 41 and three tension rollers 42, with each tension roller 42 rotatably mounted on the tape holder 4. The tape roll is mounted on the material roller 41, and the three tension rollers 42 are located between the tape roll and the wire harness, arranged in a stepped manner. The three tension rollers 42 are arranged from top to bottom as the first tension roller 421, the second tension roller 422, and the third tension roller 423, ensuring that the top of the third tension roller 423 is higher than the bottom of the second tension roller 422; and that the overall height of the third tension roller 423 is higher than the height of each fixing component 6. After the tape is drawn from the tape roll, it passes sequentially around the top of the first tension roller 421, the bottom of the second tension roller 422, and the top of the third tension roller 423, finally adhering the tape to the wire harness. During the rotation of the fixing component 6 driven by the first driving member, the wire harness is rotated, thereby causing the tape to be wound around the wire harness, thus achieving tape wrapping of the wire harness. The multiple tensioning rollers 42 are arranged to keep the tape in a taut state at all times, preventing the tape from drooping and thus avoiding the tape from not adhering to the wire harness after the wire harness is wrapped.

[0029] Reference Figure 3 The translation module 2 includes a drive motor 21, a drive roller 22 (not shown in the figure), a driven roller 23 (not shown in the figure), and a conveyor belt 24. The drive roller 22 is fixedly mounted on the shaft of the drive motor 21, and the driven roller 23 is rotatably mounted on the frame 1, with the conveyor belt wrapped around the periphery of the drive roller 22 and the driven roller 23. A slide rail 12 parallel to the conveyor belt 24 is horizontally fixed on the frame 1, and a fixing block 31 and a slide block 32 are fixedly mounted on the bottom end of the support plate 3, so that the fixing block 31 is fixed to the conveyor belt 24 and the slide block 32 is locked onto the slide rail 12. The drive roller 22 is driven to rotate by the drive motor 21, thereby driving the conveyor belt 24 to move, thus causing the support plate 3 to slide horizontally. During the horizontal movement of the support plate 3, the entire wire harness can be coated with adhesive.

[0030] Reference Figures 4-8 The fixing assembly 6 includes a fixing base 61, a cover plate 62, and a locking member 66. The locking member 66 includes a hinge block 63 and a locking hook 64. The rotating rod 7 is fixed to one side of the fixing base 61. A receiving hole 611 is formed on the surface of the fixing base 61, and the wiring harness terminal is placed in the receiving hole 611. The bottom end of the cover plate 62 is hinged to the bottom end of the surface of the fixing base 61. After the wiring harness terminal is placed in the receiving hole 611, the cover plate 62 is placed on the surface of the fixing base 61, so that a receiving groove 612 is formed between the cover plate 62 and the fixing base 61, and the end of the wire near the terminal is confined within the receiving groove 612. The hinge block 63 is fixedly mounted on the top of the cover plate 62. A hinge groove 631 is formed in the hinge block 63. The locking hook 64 consists of a rod part 641 and a hook part 642. The rod part 641 of the locking hook 64 is placed in the hinge groove 631 and hinged to the hinge block 63. After the cover plate 62 is placed on the fixing seat 61, the locking hook 64 is flipped over and hooked onto the fixing seat 61, so that the rod part 641 of the locking hook 64 abuts against the top of the fixing seat 61, so that the fixing seat 61 is limited between the hook part 642 of the locking hook 64 and the cover plate 62. In order to keep the locking hook 64 hooked on the fixing seat 61 in a stable position, a screw 65 is threadedly connected to the hinge block 63. Tightening the screw 65 makes it press against the locking hook 64 to prevent the locking hook 64 from disengaging from the fixing seat 61. The wire harness is secured by the fixing component 6, which not only provides a firm fixation but also prevents damage to the wiring terminals of the wire harness.

[0031] Reference Figure 9 The drive mechanism 5 includes a drive motor 51, a drive rod 52, four drive wheels 53, four driven wheels 54, and four synchronous belts 55. The drive motor 51 is horizontally positioned, and the drive rod 52 is fixed to the shaft of the drive motor 51. The four drive wheels 53 are fixed to the drive rod 52, and the four driven wheels 54 are respectively fixed to each rotating rod 7. The synchronous belts 55 are wrapped around the drive wheels 53 and driven wheels 54. The rotation of the shaft of the drive motor 51 drives the drive rod 52 to rotate, which in turn drives the fixing component 6 to rotate via the synchronous belts 55. During the rotation of the fixing component 6, the tape is wound around the wire harness, and in conjunction with the translation module 2, the tape holder 4 moves horizontally, thereby enabling tape wrapping to be achieved on the entire wire harness. This wire harness wrapping machine has two pairs of fixing components 6, which cooperate with two tape holders 4, thus enabling simultaneous tape wrapping of two wire harness segments and improving the efficiency of wire harness wrapping.

[0032] The specific implementation principle of this application embodiment is as follows: When the wire harness coating machine is needed to coat the wire harness, the tape roll is installed on the material roller 41 of the tape holder 4, and the two ends of the wire harness are respectively placed in the receiving holes 611 of the two fixed seats 61. Then, the cover plate 62 is flipped over so that the cover plate 62 covers the fixed seat 61, so that the end of the wire harness is limited between the fixed seat 61 and the cover plate 62. Then, the locking hook 64 is flipped over so that it hooks onto the fixed seat 61. At this time, the rod part 641 of the locking hook 64 abuts against the fixed seat 61, so that the fixed seat 61 is limited between the hook part 642 of the locking hook 64 and the cover plate 62. Finally, the screw 65 is tightened to abut against the rod part 641 of the locking hook 64 to prevent the hook part 642 of the locking hook 64 from disengaging from the fixed seat 61.

[0033] When wrapping the wire harness with adhesive, the tape roll is mounted on the feed roller 41 of the tape holder 4. After the tape is drawn out, it passes sequentially around the top of the first tensioning roller 421, the bottom of the second tensioning roller 422, and the top of the third tensioning roller 423, finally adhering the tape to the wire harness. The shaft of the drive motor 51 rotates, thereby driving the drive rod 52 to rotate. Under the transmission of the drive wheel 53, the driven wheel 54, and the synchronous belt 55, the fixing component 6 and the wire harness rotate. During the rotation of the wire harness, the tape is wound around it. At the same time, the shaft of the drive motor 21 rotates, driving the conveyor belt 24 to move, thereby moving the support plate 3 and the tape holder 4, thus enabling the entire section of the wire harness to be wrapped with adhesive. The multiple tensioning rollers 42 on the tape holder 4 are arranged to ensure that the tape is always in a taut state, preventing the tape from drooping and thus avoiding the tape not adhering to the wire harness after wrapping.

[0034] The present invention has been described above by way of example with reference to the accompanying drawings. Obviously, the specific implementation of the present invention is not limited to the above-described manner. Any non-substantial improvements made using the inventive concept and technical solution of the present invention, or the direct application of the inventive concept and technical solution to other situations without modification, shall be protected by the present invention.
