Description

Technical Field

[0001] This invention relates to the field of wire harness wrapping, and more specifically, to a wrapping apparatus for automotive wire harness production. Background Technology

[0002] With the continuous improvement of automotive electronics and intelligence, automotive wiring harnesses, as the "neural network" of the vehicle's electrical system, are becoming increasingly numerous and complex. Wiring harness wrapping is one of the key processes in automotive wiring harness production. By wrapping tape, corrugated tubing, or braided mesh around the wire harness, it serves to provide insulation protection, wear and cut resistance, noise reduction, flame retardancy, and wire harness shaping.

[0003] Traditional wire harness wrapping methods often involve manual hand-wrapping of tape, which is not only inefficient but also highly dependent on the operator's skill level, easily leading to uneven tape wrapping, inconsistent overlap, and unsuitable tightness. Chinese Patent CN212146833U discloses an automotive wire harness wrapping device, but it can only wrap a single layer of tape. When the wire harness needs to be wrapped with multiple layers of different tapes, it requires multiple tape roll changes or multiple processes, resulting in low efficiency. Furthermore, existing devices typically require stopping when encountering wire harness branches, affecting production continuity. Additionally, the tape wrapping angle and wrapping method cannot be flexibly adjusted, making it difficult to meet the differentiated wrapping requirements of different wire harnesses.

[0004] To address this, a wrapping device for automotive wiring harness production is proposed, which can simultaneously wind multiple layers of different tapes and flexibly adjust the tape winding angle to adapt to different wrapping processes. At the same time, it can achieve non-stop processing at the wiring harness bifurcation point, significantly improving the wrapping efficiency and quality of the wiring harness. Summary of the Invention

[0005] To address the problems existing in the prior art, the present invention aims to provide a wrapping device for automotive wiring harness production. By setting multiple rotating columns circumferentially distributed in the inner ring of the drive disc, each rotating column can independently hold different types or colors of adhesive tape. In one rotation, multiple layers of different adhesive tapes can be simultaneously wrapped. Compared with the traditional method that requires multiple wrappings, the wrapping efficiency is greatly improved. At the same time, the simultaneous wrapping of multiple layers of adhesive tape also facilitates the peeling of layers during subsequent maintenance, improving maintenance convenience.

[0006] To solve the above problems, the present invention adopts the following technical solution.

[0007] A wrapping device for automotive wiring harness production includes a housing, a motor fixedly connected to the front side of the housing, a mounting plate fixedly connected to the top of the housing, a drive plate rotatably connected inside the mounting plate, and a plurality of fixing mechanisms arranged in a ring array on the inner ring of the drive plate. The fixing mechanism includes a first connecting block fixedly connected to the drive disk, a second connecting block fixedly connected to the front side of the first connecting block, and a rotating column fixedly connected to the end of the second connecting block away from the first connecting block.

[0008] Furthermore, a receiving groove is provided between the second connecting block and the rotating column, and the second connecting block and the rotating column are rotatably connected through the receiving groove; a limit rod is rotatably connected to the front end of the rotating column, and a drive rod is slidably connected inside the rotating column.

[0009] Furthermore, the rotating column has an internal receiving groove to accommodate the rotation of the limiting rod, and an arc-shaped plate is fixedly connected to one end of the driving rod near the receiving groove. The side of the arc-shaped plate near the receiving groove extends toward the receiving groove to form a limiting tooth.

[0010] Furthermore, an extension block is fixedly connected to the bottom of the drive rod, a first spring is fixedly connected inside the rotating column at the location corresponding to the movement trajectory of the extension block, and a mounting shell is fixedly connected to the rear side of the outer casing.

[0011] Furthermore, the mounting housing is provided with a limiting mechanism inside. The limiting mechanism includes a pressure rod that is slidably connected to the mounting housing. A pressure plate is fixedly connected to the front end of the pressure rod, and the top of the pressure plate extends toward the drive disc to form an insertion rod.

[0012] Furthermore, the drive plate has an arc-shaped groove near the extension rod, the pressure plate has a second spring welded to the center of the mounting plate, and a cylinder is fixedly connected to the surface of the outer shell, with the second spring sleeved on the surface of the cylinder.

[0013] Furthermore, multiple rotating columns are provided, and the multiple rotating columns are evenly distributed along the inner circumference of the drive disk. The limiting teeth are engaged in the interior of the receiving groove to change the second connecting block and the rotating columns from a rotating state to a fixed state.

[0014] Furthermore, when the limiting rod is erected, it compresses the driving rod, causing the driving rod to slide inside the rotating column. When the extension block moves, it compresses the first spring, causing the first spring to change from a naturally extended state to a taut state.

[0015] Furthermore, when the extension rod extends into the interior of the arc-shaped groove, the extension rod abuts against the groove wall of the arc-shaped groove, thereby limiting the position of the drive disc.

[0016] Furthermore, when the pressure plate is pressed, it compresses the second spring, causing the second spring to deform and drive the pressure plate to reset. The motor drives the drive disc to rotate via a synchronous belt or gear transmission.

[0017] Compared with the prior art, the beneficial effects of the present invention are as follows: This solution uses multiple rotating columns circumferentially distributed within the inner ring of the drive disc. Each rotating column can independently hold different types or colors of tape. In a single rotation, multiple layers of different tapes can be simultaneously wrapped and coated. Compared to the traditional method that requires multiple wrappings, this significantly improves the coating efficiency. At the same time, the simultaneous wrapping of multiple layers of tape also facilitates the peeling off of layers during subsequent maintenance, improving the convenience of repair.

[0018] This solution utilizes a rotating connection structure between the rotating column and the second connecting block, allowing the rotating column to rotate and be fixed at different angles around the second connecting block. This enables the tape to be wound around the wire harness surface at different tilt angles, achieving switching between various winding processes such as half-coverage, one-third-coverage, and patterned wrapping. Users only need to pre-adjust the tilt angle of each rotating column according to process requirements to meet complex covering requirements in a single winding process, significantly improving the process adaptability and versatility of the device.

[0019] This solution uses a limit rod to drive the drive rod to move, causing the limit teeth on the arc plate to engage in the receiving groove, thus achieving rapid locking of the rotation angle of the rotating column. At the same time, the extension block at the bottom of the drive rod, in conjunction with the reset action of the first spring, allows the limit teeth to quickly disengage from the receiving groove when the limit rod flips, enabling readjustment of the rotation angle of the column. The operation is simple and quick, and the locking is reliable.

[0020] This solution utilizes the cooperation of the pressure rod, pressure plate, and extension rod in the limiting mechanism. When the wire harness encounters a fork, simply pressing the pressure rod causes the extension rod to engage in the arc-shaped groove of the drive plate, temporarily locking the drive plate and aligning its opening with the mounting plate. This facilitates the introduction of the branch wire harness into the center of the device for synchronous wrapping. After releasing the pressure rod, the extension rod automatically resets under the action of the second spring, and the drive plate continues to rotate. This achieves non-stop processing at the wire harness fork, significantly improving the continuity and production efficiency of wire harness wrapping. Attached Figure Description

[0023] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of the present invention, and not all of them. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without creative effort are within the scope of protection of the present invention. Please see Figures 1 to 7 A wrapping device for automotive wiring harness production includes a housing 1, a motor 2 fixedly connected to the front side of the housing 1, a mounting plate 3 fixedly connected to the top of the housing 1, and a drive plate 31 rotatably connected inside the mounting plate 3. The motor 2 drives the drive plate 31 to rotate via a synchronous belt or gear transmission. This is prior art and will not be described further here.

[0024] The inner ring of the drive disk 31 is provided with a plurality of fixing mechanisms 4 arranged in a ring array. The fixing mechanism 4 includes a first connecting block 41 fixedly connected to the drive disk 31. A second connecting block 42 is fixedly connected to the front side of the first connecting block 41. The end of the second connecting block 42 away from the first connecting block 41 is rotatably connected to a rotating column 43 through a receiving groove 432.

[0025] Pass the automotive wiring harness through the central through hole of the mounting plate 3, and then fix different types or colors of tape onto the surface of each rotating column 43. Start the motor 2, and the motor 2 drives the drive plate 31 to rotate. At this time, the first connecting block 41, the second connecting block 42, and the rotating column 43 wrap the automotive wiring harness with tape, making the wrapping more convenient and eliminating the need for manual wrapping.

[0026] Multiple rotating posts 43 are provided. By placing different types of tape on different rotating posts 43, the type of tape to be wrapped for each layer of the automotive wiring harness can be adjusted, making it more convenient to wrap the automotive wiring harness with tape. It can also be adjusted according to the process requirements of the automotive wiring harness wrapping. Multiple layers of different tapes can be wrapped simultaneously in one wrapping. After multiple layers of tape are wrapped simultaneously, it is more convenient to remove the tape used for wrapping the automotive wiring harness.

[0027] like Figure 6 and Figure 7 As shown, the second connecting block 42 and the rotating column 43 are rotatably connected through the receiving groove 432, allowing the rotating column 43 to rotate around the second connecting block 42 to any angle before being fixed. This causes the tape on the surface of the rotating column 43 to be in an inclined state. When the first connecting block 41 rotates along with the second connecting block 42 and the rotating column 43, the rotating column 43 can rotate along with the inclined tape, allowing the tape to wrap around the automotive wiring harness while moving forward along the axial direction, making wrapping more convenient. The tilt angle of the tape can be controlled according to the rotation angle of the rotating column 43, making it easy to control the wrapping method of the tape on the automotive wiring harness, such as half-wrapping, one-third-wrapping, or zigzag wrapping, resulting in a better wrapping effect on the automotive wiring harness. The device can be adjusted according to the wrapping method, making its application range wider.

[0028] The front end of the rotating column 43 is rotatably connected to a limiting rod 44 via a rotating shaft. After the tape roll is placed on the surface of the rotating column 43, the limiting rod 44 is rotated to make it stand up, which is used to prevent the tape from coming off the surface of the rotating column 43. A drive rod 45 is slidably connected inside the rotating column 43. During the process of rotating the limiting rod 44 to make it stand up, the end of the limiting rod 44 exerts downward pressure on the top of the drive rod 45. The rotating column 43 has a receiving groove 431 inside to accommodate the rotation of the limiting rod 44, which facilitates the rotation of the limiting rod 44.

[0029] An arc-shaped plate 453 is fixedly connected to one end of the drive rod 45 near the receiving groove 432. The side of the arc-shaped plate 453 near the receiving groove 432 extends toward the receiving groove 432 to form a limiting tooth 454. When the drive rod 45 moves downward, it moves the arc-shaped plate 453 and the limiting tooth 454 toward the receiving groove 432. The limiting tooth 454 is engaged in the tooth groove of the receiving groove 432, thereby fixing the receiving groove 432 and changing the second connecting block 42 and the rotating column 43 from a rotating state to a fixed state, so that the tilt angle of the rotating column 43 is locked.

[0030] An extension block 452 is fixedly connected to the bottom of the drive rod 45. When the drive rod 45 moves, it moves downward with the extension block 452. A first spring 451 is fixedly connected inside the rotating column 43 at the corresponding movement trajectory of the extension block 452. When the extension block 452 moves downward, it stretches or compresses the first spring 451, causing the first spring 451 to change from a naturally extended state to a taut state. This allows the drive rod 45 to return to its original position under the action of the first spring 451, making the device reusable. When it is necessary to unlock, simply turn the limit rod 44 back to the horizontal state. The drive rod 45 will reset upward under the action of the first spring 451, the limit tooth 454 will disengage from the receiving groove 432, and the rotating column 43 will return to a rotatable state.

[0031] like Figure 1 , Figure 2 , Figure 3 As shown, when the automotive wiring harness is wound to the fork position, the rear side of the housing 1 is fixedly connected to the mounting housing 5. The mounting housing 5 is provided with a limiting mechanism 6. The limiting mechanism 6 includes a pressure rod 62 that is slidably connected to the mounting housing 5. By pressing the pressure rod 62, the pressure rod 62 extends into the interior of the mounting housing 5. A pressure plate 61 is fixedly connected to the front end of the pressure rod 62. By pressing the pressure rod 62, the pressure plate 61 can be controlled to move towards the mounting plate 3.

[0032] The top of the pressure plate 61 extends toward the drive plate 31 to form an insertion rod 65. By pressing the pressure plate 61, the insertion rod 65 moves toward the drive plate 31. The drive plate 31 has an arc-shaped groove 311 near the insertion rod 65. At this time, the insertion rod 65 can be inserted into the interior of the arc-shaped groove 311. The drive plate 31 rotates, causing the arc-shaped groove 311 to rotate as well. At this time, the insertion rod 65 abuts against the groove wall of the arc-shaped groove 311, thereby limiting the drive plate 31. At this time, the opening of the arc-shaped groove 311 is opposite to the opening of the mounting plate 3, which makes it convenient for the opening of the drive plate 31 to coincide with the opening of the mounting plate 3. At this time, other branch automotive wiring harnesses can be introduced into the middle of the device through the coincident opening, which facilitates the synchronous winding of multiple strands of automotive wiring harnesses without the need for a stop device.

[0033] A second spring 63 is welded to the middle of the pressure plate 61 near the mounting plate 3. A cylinder 64 is fixedly connected to the surface of the outer shell 1. The second spring 63 is sleeved on the surface of the cylinder 64, and the cylinder 64 guides the second spring 63. When the pressure plate 61 is pressed, the pressure plate 61 compresses the second spring 63, causing the second spring 63 to deform. This allows the pressure plate 61 to return to its original position under the action of the second spring 63. When the pressure rod 62 is released, the pressure plate 61 returns to its original position with the extension rod 65. At this time, the drive plate 31 can rotate again, which facilitates the wrapping of the automotive wiring harness with branches, making the wrapping more convenient.

[0034] The working process of this device is as follows: The automotive wiring harness to be wrapped is passed through the center holes of the mounting plate 3 and the drive plate 31. According to the wiring harness wrapping process requirements, different types of tape rolls are installed on the three rotating columns 43 respectively. The tilt angle of each rotating column 43 is adjusted according to the required wrapping method. Then, the limiting rod 44 is moved to make it stand up, and the drive rod 45 moves down to drive the limiting tooth 454 to engage in the receiving groove 432 to lock the angle. The motor 2 is started, and the drive plate 31 drives each rotating column 43 to rotate. The tape is wrapped around the surface of the wiring harness. When a branch of the wiring harness is encountered, the pressure rod 62 is pressed, and the extension rod 65 engages in the arc groove 311 to lock the drive plate 31, so that the opening of the drive plate 31 coincides with the opening of the mounting plate 3. After the branch wiring harness is introduced, the pressure rod 62 is released, and the drive plate 31 continues to rotate. The above process is repeated until the wiring harness is wrapped.

[0035] The above description is merely a preferred embodiment of the present invention; however, the scope of protection of the present invention is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in the present invention, based on the technical solution and its improved concepts, should be covered within the scope of protection of the present invention.
