Description

Technical Field

[0001] This utility model relates to the technical field of wire harness coating devices, specifically: an automotive wire harness coating device. Background Technology

[0002] As a crucial component of the automotive electrical system, automotive wiring harnesses are widely distributed throughout the vehicle, especially in the engine compartment where they perform complex electrical connection functions. Due to the high operating temperature inside the engine compartment, prolonged operation can easily lead to aging and cracking of the outer insulation material of the wiring harness, resulting in faults such as short circuits and poor connections, affecting the stability and safety of the entire vehicle's electrical system. Therefore, effective protection of automotive wiring harnesses is of paramount importance.

[0003] Currently, in the production and assembly of automotive wiring harnesses, a coating process is commonly used to externally protect the harnesses. Traditional coating methods rely primarily on manual operation, where workers wrap tape around the wire harness surface according to specific process requirements to achieve heat insulation, abrasion prevention, and sealing. However, this manual coating method suffers from low efficiency and poor consistency, making it difficult to meet the demands of modern automotive manufacturing for high-volume, high-quality production. Especially when handling large quantities of long wire harnesses, manual wrapping is not only time-consuming and labor-intensive but also prone to inconsistent coating quality due to improper operation, thus affecting subsequent assembly and overall vehicle performance. Utility Model Content

[0004] In view of the problems in the related technologies, this utility model proposes an automotive wiring harness wrapping device to overcome the above-mentioned technical problems existing in the existing related technologies.

[0005] Therefore, the specific technical solution adopted by this utility model is as follows:

[0006] An automotive wiring harness coating device includes a support base, positioning frames connected to both sides of the support base, a wiring harness traction mechanism on the top of the positioning frames, a fixing plate connected to one side of the support base, a worm gear ring rotatably mounted on one side of the fixing plate, and a coating mechanism on the surface of the worm gear ring.

[0007] Furthermore, in order to clamp and pull the wire harness that needs to be coated, the wire harness pulling mechanism includes a support plate connected to the top of the positioning frame, a limit rod slidably installed on one side of the surface of the support plate, an adjustment plate connected to the top of the limit rod, a pulling groove between the support plate and the adjustment plate, double conical wheels rotatably installed on both sides of the pulling groove, a lifting screw rotatably connected to one side of the support plate, and the lifting screw threadedly connected to the adjustment plate.

[0008] Furthermore, in order to achieve automated transmission of the clamped wire harness, a pair of drive motors are installed in the traction groove on the side of the positioning frame near the fixed plate, and a limit ring is installed on the other side. The output end of the drive motor is connected to the double conical wheel, and the top of the limit ring is rotatably connected to an adjusting bolt. The adjusting bolt is threadedly connected to the adjusting plate, and the limit ring is engaged with one end of the double conical wheel.

[0009] Furthermore, in order to achieve automated coating of the traction drive wiring harness, the coating mechanism includes a driven plate connected to the inner wall of the worm gear ring, a rotating shaft rotatably connected to one side surface of the driven plate, a roll of tape mounted on the surface of the rotating shaft, and a limit bolt threaded to one side of the rotating shaft.

[0010] Furthermore, in order to provide power for the rotation of the rubber coating mechanism, a second drive motor is installed on one side of the fixed plate. The output end of the second drive motor is connected to a drive worm, which meshes with the worm wheel ring.

[0011] Furthermore, in order to increase the friction between the double conical wheel 305 and the wire harness, the surface of the double conical wheel 305 is provided with an anti-slip rubber pad.

[0012] Furthermore, to facilitate the adjustment of the lifting screw, a turning head is connected to one end of the lifting screw.

[0013] Furthermore, in order to control the starting and speed of drive motor one and drive motor two, a multi-control switch is installed on one side of the surface of the fixed plate.

[0014] Furthermore, in order to enable the support base to move, casters are rotatably installed on both sides of the bottom surface of the support base.

[0015] The beneficial effects of this utility model are as follows: Through the wire harness traction mechanism, the two pairs of double conical wheels at the top of the two positioning frames clamp and limit the wire harness that needs to be coated. Then, the transmission motor drives one pair of double conical wheels to rotate, so that the double conical wheels can drive the wire harness to achieve automated traction transmission. During the wire harness transmission process, through the coating mechanism, the worm gear ring can drive the tape to rotate around the wire harness, thereby realizing the automated coating process on the surface of the automotive wire harness, which greatly shortens the processing time of a single wire harness. It is especially suitable for the mass processing of long wire harnesses or complex structure wire harnesses, and can effectively reduce labor costs and improve the consistency and reliability of the overall product after coating.

[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0026] According to an embodiment of the present invention, an automotive wiring harness encapsulation device is provided.

[0027] like Figures 1-6 As shown, an automotive wiring harness coating device according to an embodiment of this utility model includes a rectangular metal support base 1. A pair of positioning frames 2 are connected to both sides of the surface of the support base 1. A wiring harness traction mechanism 3 is provided on the top of the positioning frames 2, used to automatically drive the wiring harness to be coated, thereby facilitating coating processing on various parts of the wiring harness surface. A fixing plate 4 is connected to one side of the surface of the support base 1, and the fixing plate 4 is installed between the two positioning frames 2. A worm gear ring 5 is rotatably mounted on one side of the surface of the fixing plate 4. A coating mechanism 6 is provided on the surface of the worm gear ring 5, used to drive the tape to be evenly wound around the surface of the wiring harness, realizing automated coating processing of the wiring harness; wiring harness traction... Mechanism 3 includes two positioning frames 2 with support plates 301 connected to their tops. A limit rod 302 is slidably mounted on one side of the support plate 301. An adjusting plate 303 is connected to the top of the limit rod 302. A traction groove 304 is provided between the support plate 301 and the adjusting plate 303. A pair of double conical wheels 305 are rotatably mounted on both sides of the traction groove 304. A lifting screw 306 is rotatably connected to one side of the support plate 301. The lifting screw 306 is threadedly connected to the adjusting plate 303. The wire harness to be traction-transmitted is placed between the two pairs of double conical wheels 305 on the tops of the two positioning frames 2. By turning the lifting screw 306, the position of the support plate 301 and the adjusting plate 303 is adjusted. The distance between 03 allows the two pairs of double conical wheels 305 to clamp and limit the wire harness, causing the automotive wire harness to move in the direction of rotation of the double conical wheels 305; a pair of drive motors 307 are installed in the traction groove 304 on the side of the two positioning frames 2 near the fixed plate 4, and a limit ring 308 is installed in the traction groove 304 on the other side away from the fixed plate 4. The output ends of the two drive motors 307 are respectively connected to the two double conical wheels 305. The drive motors 307 drive the two double conical wheels 305 to rotate, causing the double conical wheels 305 to drive the clamped wire harness to move in the direction of rotation through friction, thereby realizing the linear transmission of the wire harness; the limit ring 308 An adjusting bolt 309 is rotatably connected to the top. The adjusting bolt 309 is threadedly connected to the adjusting plate 303. The limiting ring 308 cooperates with one end of the double cone wheel 305. By turning the adjusting bolt 309, the pressure of the limiting ring 308 on one end of the double cone wheel 305 is changed, thereby increasing the friction between the limiting ring 308 and one end of the double cone wheel 305 after contact. This makes the double cone wheel 305 closer to the fixed plate 4 require a greater traction force to drive the double cone wheel 305 away from the fixed plate 4 to rotate through the wire harness. This achieves a taut state for the wire harness between the two pairs of double cone wheels 305 during traction transmission, making it convenient to evenly wrap the tape around the wire harness.

[0028] like Figures 1-6As shown, the coating mechanism 6 includes a driven plate 601 connected to one side of the inner wall of the worm gear ring 5. A rotating shaft 602 is rotatably connected to one side surface of the driven plate 601. A tape roll 603 is mounted on the surface of the rotating shaft 602. The tape roll 603 is made of wound tape and can continuously supply tape to the coating mechanism 6. A limit bolt 604 is threaded to one side of the rotating shaft 602 to limit the tape roll 603 on the rotating shaft 602. After unscrewing and disassembling, the tape roll 603 on the rotating shaft 602 can be replaced. A second drive motor 605 is mounted on one side of the fixed plate 4. A drive worm 606 is connected to the output end of the second drive motor 605. The drive worm 606 meshes with the worm gear ring 5. The second drive motor 605 drives the drive worm 606 to rotate, so that the drive worm 606 can continuously drive the worm gear ring 5 to rotate, thus coating the tape roll 603. After one end of the tape is manually wound onto the wire harness, the worm gear ring 5 drives the tape roll 603 to rotate continuously around the wire harness, so that the tape is evenly wound on the surface of the wire harness; the surface of the double conical wheel 305 is provided with anti-slip rubber pads 7, which are used to increase the friction between the surface of the double conical wheel 305 and the wire harness, and prevent the wire harness from slipping when it is transmitted between the double conical wheels 305; one end of the lifting screw 306 is connected to a turning head 8, which is used to easily turn and adjust the lifting screw 306; a multi-control switch 9 is installed on one side of the surface of the fixed plate 4, which is electrically connected to the drive motor 1 307 and the drive motor 2 605 through wires, and is used to control the switching and speed of the drive motor 1 307 and the drive motor 2 605; two pairs of universal wheels 10 are rotatably installed on both sides of the bottom surface of the support base 1, which are used to move the support base 1 and facilitate the movement of the whole device.

[0029] In practical use, the wire harnesses to be traction and transmitted are placed between two pairs of double conical wheels 305 on the top of the two positioning frames 2. By turning the lifting screw 306, the distance between the support plate 301 and the adjusting plate 303 is changed, so that the two pairs of double conical wheels 305 clamp the wire harness and move the automotive wire harness in the direction of rotation of the double conical wheels 305. After manually winding one end of the tape on the tape roll 603 onto the wire harness, the drive motor 1 307 and the drive motor 2 605 are started. The drive motor 1 307 drives the two double conical wheels 305 to rotate relative to each other, so that the double conical wheels 305 drive the clamped wire harness to move in the direction of rotation through friction, thereby realizing the linear transmission of the wire harness. The drive motor 2 605 drives the drive worm gear 606 to rotate, so that the drive worm gear 606 can continuously drive the worm wheel ring 5 to rotate. The worm wheel ring 5 can drive the tape roll 603 to rotate continuously around the wire harness, so that the tape is evenly wrapped on the surface of the wire harness with uniform speed transmission, realizing the automated coating process of the automotive wire harness.
