Technical Field

[0001] This utility model relates to the field of automotive wiring harness processing technology, specifically to a winding and wrapping device for automotive wiring harnesses. Background Technology

[0002] With the increasing functionality of automobiles and the widespread application of electronic control technology, there are more and more electrical components, leading to a greater number of automotive wiring harnesses. The number of circuits and power consumption in automobiles have increased significantly, making the wiring harnesses thicker and heavier. This presents a major challenge: how to more effectively and rationally arrange a large number of wiring harnesses within the limited space of a car, and how to maximize their functionality, has become a problem facing the automotive manufacturing industry.

[0003] Currently, whether it's a high-end luxury car or an economy car, the form of automotive wiring harnesses is basically the same. They consist of automotive wiring harnesses, connectors, and wrapping tape. If the tape wrapping of the wiring harness is done manually, firstly, it cannot guarantee the consistency of the wiring harness quality, and secondly, it requires a lot of effort from workers, resulting in low production efficiency. More importantly, if the manual wrapping is too sparse, there will be gaps; if it is too dense, it will waste tape, increase costs, and result in uneven thickness and an unsightly appearance. Utility Model Content

This device has advantages such as stable adhesion, tape saving, adjustable number of wraps, fast wrapping speed, and strong adaptability to tape.

[0005] To achieve the above objectives, the technical solution adopted by this utility model is as follows: a winding and wrapping device for automotive wiring harnesses, comprising a frame, an electrical control component, a feeding component, and a winding component; the feeding component, located on the upper part of the frame, includes a tape fixing frame and a feeding roller, and a cutting component for cutting the tape is provided on one side of the feeding roller; the winding component includes a U-shaped chuck, a proximity switch group, a power component, and a winding drum, and the power component includes a power component and several transmission gear discs; the feeding component is used to provide winding tape, which is quantitatively cut by the cutting component, and the winding component is used to wrap and wrap the wiring harness.

[0006] As a further provision of the above scheme, the transmission gear disk includes a transmission gear disk and an end gear disk that is linked with the winding barrel, the end gear disk being rotatably disposed relative to the U-shaped chuck.

[0007] As a further feature of the above solution, the U-shaped chuck is provided with a slide rail on its outer side, and the slide rail is provided with a gripper and a slider, the slider being connected to a drive cylinder.

[0008] As a further feature of the above scheme, the proximity switch group is located on the outside of the gripper and is fixed relative to the gripper, and is driven to move relative to the U-shaped chuck by the drive cylinder.

[0009] As a further feature of the above solution, the feeding assembly is also equipped with a feeding motor, which is linked to the feeding rollers via a belt. Several guide rollers are also provided between the motor and the tape fixing frame and are rotatably arranged relative to the frame. The guide rollers are used to adjust the conveying direction of the tape and to tighten the tape.

[0010] As a further feature of the above solution, the cutting assembly includes a fixed blade, a movable blade plate, and a crank arm. The crank arm is connected to a swing arm, and a cutting motor is also provided on the frame. The cutting motor is connected to a cam assembly, and the rotation of the cam assembly drives the swing arm to move the crank arm and the movable blade plate relative to the fixed blade.

[0011] As a further feature of the above solution, the rack is also equipped with a touch screen assembly for electronic control components and a power switch for controlling the equipment.

[0012] Beneficial effects: This practical equipment features automatic pre-feeding of tape, which is then cut to a preset length.

Detailed Implementation

[0019] To better understand the above-mentioned objectives, features, and advantages of this utility model, the present utility model will be further described in detail below with reference to the accompanying drawings and specific embodiments. It should be noted that, where there is no conflict, the embodiments and features described in these embodiments can be combined with each other.

[0020] like Figure 1-5 The present invention discloses a winding and wrapping device for automotive wiring harnesses. The device in this embodiment includes a frame 1, on which an electrical control component, a feeding component 3, and a winding component 2 are installed. The outer side of the frame 1 is covered with a housing, and an operation port is provided on the front. The winding component 2 is located at the operation port, which is used by the operator to place the wiring harness and unload the wound wiring harness from the operation port.

[0021] Furthermore, in this embodiment, the feeding assembly 3 is located on the upper part of the frame 1. The feeding assembly 3 includes a tape fixing frame 31 and a feeding roller 32. A cutting assembly 4 for cutting the tape is provided on one side of the feeding roller 32. A feeding motor 33 is also provided on the feeding assembly 3. The feeding motor 33 is linked to the feeding roller 32 via a belt. A plurality of guide rollers 34 are also provided between the feeding motor 33 and the tape fixing frame 31 and rotate relative to the frame 1. The guide rollers 34 are used to adjust the conveying direction of the tape and tighten the tape. When the equipment is working, the operator puts the wrapping tape into the tape fixing frame 31 in advance and wraps the tape end around the guide roller 34 and connects it to the feeding roller 32. After the equipment is officially started, the wrapping equipment automatically pre-feeds the tape according to the parameters set by the electronic control assembly and triggers the cutting assembly 4 to cut according to the preset length.

[0022] The cutting assembly 4 in this embodiment includes a fixed blade 41, a movable blade plate 42, and a crank arm 43. The crank arm 43 is connected to a swing arm 44. A cutting motor 45 is also provided on the frame 1. The cutting motor 45 is connected to a cam assembly 46. By driving the rotation of the cam assembly 46, the swing arm 44 is driven to move the crank arm 43 and the movable blade plate 42 relative to the fixed blade 41. A sensor 47 is also provided on the side of the cam assembly 46 to provide feedback on the position of the cam assembly 46, thereby satisfying the position control of the cutting motor 45 and the movable blade plate 42 by the electronic control assembly. In use, the cutting motor 45 starts to rotate to provide power, which drives the cam assembly 46 to rotate and drive the swing arm 44 to swing. Based on the rotation of the swing arm 44 and the crank arm 43 along the central axis, the crank arm 43, with the movable blade plate 42 fixed to it, moves relative to the fixed blade 41 to form a shearing action to cut the tape.

[0023] The winding assembly 2 in this embodiment includes a proximity switch group 22 for determining wire harness loading and unloading, a power assembly 23 for providing driving force to the winding assembly 2, a U-shaped chuck 21 fixed relative to the frame 1, and a winding drum 24 that moves relative to the U-shaped chuck 21 based on the power assembly 23 driving the winding drum 24. The power assembly 23 in this embodiment includes a power component 231 and several transmission gear discs 232, such as... Figure 4 , 5 The transmission gear disk 232 shown includes a transmission gear disk 238 and an end gear disk 237 that is linked with the winding drum 24. The end gear disk 237 is rotatably arranged relative to the U-shaped chuck 21. After the power component 231 is started, the transmission gear disk 232 is driven to start. The meshing transmission gear disk 238 and the end gear disk 237 rotate, driving the winding structure linked with the end gear disk 237 to rotate and wind the wire harness.

[0024] As described above, the feeding component 3 of this embodiment is used to provide the wrapping tape, which is quantitatively cut by the cutting component 4, and the wrapping component 2 is used to wrap and wind the wire harness.

[0025] As a further feature of the above solution, the U-shaped chuck 21 is provided with a slide rail 211 on its outer side. The slide rail 211 is provided with a gripper 212 and a slider 213. The slider 213 is connected to a drive cylinder 214. The proximity switch group 22 is located on the outer side of the gripper 212 and is fixedly positioned relative to the gripper 212. The drive cylinder 214 drives the relative movement of the U-shaped chuck 21. The drive cylinder 214 is activated after the proximity switch group 22 detects the wire harness, driving the slider 213, the gripper 212 holding the wire harness, and the proximity switch group 22 to move downwards simultaneously, allowing the wire harness to enter the bottom of the U-shaped groove of the U-shaped chuck 21. Then the winding assembly 2 is activated. After winding is completed, the drive cylinder 214 is activated again to deliver the wire harness, allowing the operator to conveniently unload the wire harness from the operating port.

[0026] As a further provision of the above scheme, the rack 1 is also provided with a touch screen assembly 81 for electronic control components and a power switch 82 for controlling the equipment.

[0027] As described above, the wrapping equipment of this invention uses an automatic pre-feeding tape, which is then cut to a preset length. The operator then places the wire harness at the winding position. Once the proximity switch detects the product, the winding mechanism begins to wrap it. After winding is complete, the equipment automatically stops, and the operator unloads the material. The process continuously cycles, with quantitative cutting saving raw materials and reducing production costs. The automatic and rapid wrapping process improves efficiency, thereby increasing profits.

[0028] Obviously, those skilled in the art can make various modifications and variations to this utility model without departing from its spirit and scope. Therefore, if these modifications and variations fall within the scope of this utility model and its equivalents, this utility model also intends to include these modifications and variations.
