Description

Technical Field

[0001] This invention relates to the field of automotive wiring harness processing equipment technology, and in particular to a coating processing device for automotive wiring harness production. Background Technology

[0002] As the core transmission carrier of automotive circuits, the quality of automotive wiring harness coating directly determines the insulation performance, wear resistance, and overall vehicle electrical safety. This is especially true for high-voltage wiring harnesses and irregularly shaped multi-branch wiring harnesses in new energy vehicles, which require extremely high standards for coating tightness, tape wrapping uniformity, and the absence of wrinkles and bubbles. Existing automotive wiring harness coating equipment, whether semi-automatic benchtop coating machines, handheld winding equipment, or conventional fully automatic coating equipment, generally suffers from the following insurmountable technical defects, which existing patents and commercial products have not effectively resolved. Currently, automotive wiring harness wrapping is typically performed on a production line. The wiring harness is fixed on an inclined work surface, and workers manually wrap the wiring harness with tape. It is difficult to maintain uniformity in terms of tape spacing and overlap, tape tilt angle, the angle between the tape and the wiring harness, and the degree of tape stretching during wrapping. This relies on the operator's experience, and long-term work can damage the operator's wrists, resulting in a low level of automation. Summary of the Invention

[0003] The purpose of this invention is to solve the problem of low automation in the prior art, and to propose a coating processing device for automotive wiring harness production.

[0004] To achieve the above objectives, the present invention adopts the following technical solution: a coating processing device for automotive wiring harness production, comprising a base, side plates fixedly connected to both sides of the base, movable guide rollers installed at both ends of opposite sides of the two side plates, a first guide rail seat fixedly connected to the top center of the base, a groove opened on the top of the first guide rail seat and a second guide rail seat slidably connected inside the groove, a groove opened on the top of the second guide rail seat and a lead screw rotatably connected inside the groove, a moving block slidably connected inside the groove on the top of the second guide rail seat, the moving block and the lead screw being threadedly connected, a telescopic column slidably connected to the top of the moving block, a rotating seat rotatably connected to the top of the telescopic column via a servo motor, two limiting shells installed on the top of the rotating seat, the two limiting shells being arranged in parallel, a notched gear slidably connected inside the limiting shell, a receiving groove on the outside of the notched gear, an extension gear slidably connected inside the receiving groove, and an installation roller and an adjustment mechanism installed between the two notched gears.

[0005] In the aforementioned coating processing device for automotive wiring harness production, the mounting roller is rotatably connected to both notched gears, an elastic airbag is provided at the center of the mounting roller, and a gear set is installed inside one of the notched gears, with the gear set fixedly connected to the mounting roller.

[0006] In the aforementioned coating processing device for automotive wiring harness production, a drive gear is installed at the bottom of the second guide rail seat, and a rack is installed on the inner slide groove sidewall of the first guide rail seat, with the drive gear meshing with the rack.

[0007] In the aforementioned coating processing device for automotive wiring harness production, the gap between the two limiting shells is greater than the width of the wiring harness winding tape, and the opposite side of the two limiting shells is an open structure.

[0008] In the aforementioned coating processing device for automotive wiring harness production, a limiting roller is rotatably connected inside the limiting shell. The limiting roller is made of corrosion-resistant rubber material and contacts a notched gear.

[0009] In the aforementioned coating processing device for automotive wiring harness production, a rotating gear is installed on the top of the rotating seat. The rotating gear meshes with the notched gear. After the extended gear fully extends from the receiving groove, the gear teeth and the notched gear teeth form a uniform and complete circumferential tooth. A ball bearing is installed on the part of the extended gear near the receiving groove. A locking button is installed on the bottom of the opposite side of the notched gear.

[0010] In the above-mentioned coating processing device for automotive wiring harness production, the adjustment mechanism includes an adjustment roller, a tension roller, and a pressing roller. Each of the two notched gears has a moving groove on one side opposite to the other. The moving groove corresponds to the position of the mounting roller. The two moving grooves are connected to the tension roller. Each of the two notched gears is equipped with a telescopic frame on the side facing the gear shaft. The two telescopic frames are rotatably connected to the adjustment roller. The surface of the adjustment roller is coated with an anti-adhesive coating.

[0011] In the aforementioned coating processing device for automotive wiring harness production, a rotating disk is rotatably connected to each side of the notched gear, and a pressing push rod is installed at the bottom of the rotating disk. The two pressing push rods are rotatably connected to the pressing roller.

[0012] Compared with existing technologies, the advantages of this invention are: 1. This invention achieves rapid positioning and stable clamping of wire harness materials through the fixed structure design of the base and side plates, combined with the electric push rod driven clamping mechanism of the moving guide rollers at both ends. It eliminates the need for repeated manual adjustment of the wire harness position, greatly shortening auxiliary time. The wire harness can be easily placed at the gear shaft position, reducing the difficulty of loading. The design of the locking button and storage slot allows the extension gear to be hidden and stored when not in operation to avoid interference, while in operation, it can be released and engaged with one button, simplifying the power transmission path.

[0013] 2. This invention improves the adaptability to different wire harness materials, diameters and tape characteristics through multi-structure design, and ensures the stability of the coating quality. The winding spacing and the tilt angle of the tape coverage can be precisely set as needed. The sliding adjustment function of the tension roller in the moving groove can apply a pre-stretching force to the tape before it contacts the surface of the wire harness. For tapes that need to be stretched to activate adhesion, it can promote the pressure-sensitive adhesive layer to reach the best adhesion state and prevent edge lifting or falling off.

[0014] 3. The rubber pressing roller driven by the rotating disk and pressing push rod of the present invention can always press vertically onto the surface of the freshly pasted tape with controllable pressure, and its smooth rubber surface can adapt to the bonding contour under different winding angles, expel air in real time and compact the tape, avoiding the problem of uneven tightness common in manual winding.

[0017] The following examples are for illustrative purposes only and are not intended to limit the scope of the invention.

[0018] Example Reference Figure 1-2 and Figure 7 A coating processing device for automotive wiring harness production includes a base 1, with side plates 101 fixedly connected to both sides of the base 1. The wiring harness material to be coated is placed between the side plates 101. Movable guide rollers 102 are installed at both ends of opposite sides of the two side plates 101. An electric actuator drives the movable guide rollers 102 to move closer together and clamp the wiring harness material. A first guide rail seat 2 is fixedly connected to the top center of the base 1. The coating device moves along the wiring harness direction. A groove is formed on the top of the first guide rail seat 2, and a second guide rail seat 3 is slidably connected inside the groove. A groove is formed on the top of the second guide rail seat 3, and a lead screw 302 is rotatably connected inside the groove. A movable block 4 is connected, and the movable block 4 is threadedly connected to the lead screw 302. A telescopic column 5 is slidably connected to the top of the movable block 4, which can freely adjust the working position height. The rotation of the lead screw 302 drives the movable block 4 to move, ensuring that the device reaches the appropriate working position. The top of the telescopic column 5 is connected to a rotating seat 6 via a servo motor, which can be adjusted to a suitable angle for the coating work. Two limiting shells 7 are installed on the top of the rotating seat 6. The two limiting shells 7 are arranged in parallel. A notched gear 8 is slidably connected inside the limiting shell 7. There is a storage groove 801 on the outside of the notched gear 8. An extension gear 11 is slidably connected inside the storage groove 801. An installation roller 9 and an adjustment mechanism are installed between the two notched gears 8. The installation roller 9 can quickly load and unload the rolled-up wrapping tape.

[0019] Reference Figure 5 The installation roller 9 is rotatably connected to both notched gears 8. An elastic airbag is provided at the center of the installation roller 9. A gear set 901 is installed inside one side of the notched gear 8. The gear set 901 is fixedly connected to the installation roller 9. After the elastic airbag is inflated, the installation roller 9 can quickly fix the adhesive tape, which can adapt to different sizes of wrapping tape.

[0020] Reference Figure 3 The second guide rail seat 3 is equipped with a drive gear 301 at its bottom, and a rack 201 is installed on the inner slide groove side wall of the first guide rail seat 2. The drive gear 301 meshes with the rack 201, and the rotation of the drive gear 301 enables the second guide rail seat 3 to move inside the first guide rail seat 2.

[0021] Reference Figure 3-5 The gap between the two limiting shells 7 is greater than the width of the wire harness wrapping tape. The installation of the wrapping tape can be completed by quickly removing the installation roller 9. Both limiting shells 7 have an open structure on opposite sides.

[0022] Reference Figure 5 The limiting housing 7 is rotatably connected to a limiting roller 701, which is made of corrosion-resistant rubber material. The limiting roller 701 contacts the notched gear 8 and further restricts the movement trajectory of the notched gear 8 to ensure that it can only rotate.

[0023] Reference Figure 4 A rotating gear 601 is installed on the top of the rotating seat 6. The rotating gear 601 meshes with the notched gear 8. The operation of the rotating gear 601 can make the notched gear 8 and the extension gear 11 rotate. After the extension gear 11 extends fully from the receiving groove 801, the gear teeth and the gear teeth of the notched gear 8 form a uniform and complete circumferential tooth. When the wire harness is wrapped with rubber, the winding spacing and tilt angle are adjusted by controlling the moving speed of the first guide rail seat 2 and the rotation speed of the notched gear 8. A ball bearing is installed near the receiving groove 801 of the extension gear 11 to greatly reduce the sliding friction. A locking button 10 is installed on the bottom of the opposite side of the notched gear 8. After the locking button 10 is locked, the position of the extension gear 11 is restricted to ensure that it can mesh with the rotating gear 601.

[0024] Reference Figure 6The adjustment mechanism includes an adjustment roller 13, a tension roller 141, and a pressure roller 17. Each of the two notched gears 8 has a moving groove 14 on one side, corresponding to the position of the mounting roller 9. The two moving grooves 14 are connected to the tension roller 141. Telescopic frames 12 are installed on the side of the notched gears 8 facing the gear shaft. The two telescopic frames 12 are rotatably connected to the adjustment roller 13. The raising and lowering of the telescopic frames 12 can quickly change the position of the adjustment roller 13, causing the angle between the adhesive tape and the wire harness to change, thus accommodating wire harnesses of different materials and thicknesses for wrapping. The surface of the adjustment roller 13 is coated with an anti-adhesive coating, preventing adhesion to the lower surface of the adhesive tape. When wrapping the wire harness, the winding spacing and tilt angle are adjusted by controlling the moving speed of the first guide rail seat 2 and the rotation speed of the notched gear 8. The raising and lowering of the telescopic frames 12 can quickly change the position of the adjustment roller 13. A rotating disk 15 is rotatably connected to each other on opposite sides of the notched gear 8. A pressing push rod 16 is installed at the bottom of the rotating disk 15. The two pressing push rods 16 are rotatably connected to the pressing roller 17. When the wire harness is wrapped with tape, the tape joint passes under the tension roller 141 and over the adjusting roller 13, and is finally pasted onto the surface of the wire harness. The rotating disk 15 is controlled to rotate and the pressing push rods 16 to extend and retract, so that the pressing roller 17 contacts the surface of the tape at the pasting position. The pressing roller 17 is made of rubber material and has a smooth surface, which ensures a stable pressing effect during winding and rewinding and adapts to different pressing angles.

[0025] In this invention, the base 1 is fixed in the working area. The wire harness material to be wrapped and coated is placed between the side plates 101. The electric actuator between the moving guide rollers 102 at both ends works, so that the moving guide rollers 102 move closer to each other and clamp the wire harness material. Initially, the second guide rail seat 3 is located at one end of the first guide rail seat 2. The locking button 10 is unlocked. The extension gear 11 is located inside the storage groove 801. The moving block 4 moves left and right under the drive of the lead screw 3002. The telescopic column 5 moves up and down to adjust the height. The top of the telescopic column 5 is controlled by the servo motor to freely rotate the rotating seat 6, ensuring that the wire harness can be easily placed at the axis position of the notched gear 8.

[0026] The wire harness wrapping tape is placed on the detachable mounting roller 9. An elastic air bladder is set in the center of the mounting roller 9. After inflation, the mounting roller 9 can quickly fix the tape. The gear set 901 inside the notched gear 8 rotates, and the wound tape rotates to release the tape for the wrapping work. The tape release is controlled by the electronic control system, and the release speed and tension are stable.

[0027] When wrapping the wire harness, the tape joint passes under the tension roller 141 and over the adjusting roller 13, and is finally pasted onto the surface of the wire harness. The rotating disk 15 is controlled to rotate and the pressing push rod 16 is extended and retracted, so that the pressing roller 17 contacts the upper surface of the tape at the pasting position. The pressing roller 17 is made of rubber material and has a smooth surface, which ensures a stable pressing effect during winding and rewinding, and adapts to different pressing angles.

[0028] When wrapping wire harnesses, the winding spacing and tilt angle are adjusted by controlling the moving speed of the first guide rail seat 2 and the rotation speed of the notched gear 8. The telescopic frame 12 can quickly change the position of the adjusting roller 13 by raising and lowering it, so that the angle between the adhesive tape and the wire harness changes. This allows for wrapping wire harnesses of different materials and thicknesses. The surface of the adjusting roller 13 is coated with an anti-adhesive coating so that it will not stick to the lower surface of the tape. The tension roller 141 slides inside the moving groove 14, which adaptively stretches the tape before it contacts the surface of the wire harness, promoting the tape to reach the appropriate viscosity. The winding tape maintains a stable speed when it is released. After uniform tension adjustment and contact angle adjustment, stable and efficient automated wire harness wrapping is achieved, with strong adaptability.
