Description

Technical Field

[0001] This utility model relates to a winding device, and more particularly to a wire harness tape winding device applied in the field of wire harness processing. Background Technology

[0002] A wiring harness is a group of metal wires and cables bundled together. It is used for signal and power connections between transport equipment and can be used in automobiles, home appliances, computers and communication equipment, and various electronic instruments. When processing automotive wiring harnesses, tape is generally required for wrapping.

[0003] When wrapping tape around wire harnesses, the tape is usually wrapped around the outer surface of the slowly moving wire harness. For example, Chinese Patent Publication No. CN220085723U discloses a tape wrapping device for wire harness production. This utility model uses the power shaft of a motor to drive an external gear block to rotate, the external gear block to drive the motor to rotate, and the motor to drive a rotating ring to rotate around the wire cylinder as the axis. The rotating ring drives the tape wound around the outside of the wire harness to rotate through a support component, thereby wrapping the tape around the outer surface of the slowly moving wire harness.

[0004] When tape is wrapped, air can easily get trapped between the tape and the surface of the wire harness, as well as between the layers of tape. The air trapped between the tape layers will reduce the bonding area and significantly reduce the adhesion. During subsequent handling, installation or use, the tape is prone to bubbling, curling, or even falling off completely due to vibration, temperature changes, or other reasons. Utility Model Content

[0005] In view of the above-mentioned prior art, the technical problem to be solved by this utility model is that when wrapping wire harness with tape, air is easily trapped between the tape and the surface of the wire harness, as well as between the layers of tape, which leads to a decrease in the adhesion of the tape wrapping layer and makes it easy for problems such as bubbling and loosening to occur in subsequent use.

[0006] To solve the above problems, this utility model provides a wire harness tape winding device, including a base plate, a support plate fixedly connected to the upper middle part of the base plate, a receiving hole being drilled on the surface of the support plate, and an adjusting ring and a driving ring being rotatably connected to the right end of the support plate, a motor being fixedly connected to the left end of the support plate, the output end of the motor being movably passed through the support plate and fixedly connected to the driving ring, a belt being sleeved on the outer side of the driving ring and the adjusting ring, a mounting plate being rotatably connected to the right end of the adjusting ring, an adjusting groove being drilled on the right end of the mounting plate, a screw being rotatably connected to the inner cavity of the adjusting groove, the rear end of the screw being movably passed through the mounting plate, and two clamping plates being sleeved on the external thread of the screw, and multiple extrusion components being fixedly connected to the inner wall of the receiving hole, the extrusion components including an outer tube fixedly connected to the inner wall of the receiving hole, a compression spring being fixedly connected to the circular inner wall of the outer tube, an inner rod being fixedly connected to the end of the compression spring away from the inner wall of the receiving hole, a mounting block being fixedly connected to the end of the inner rod away from the compression spring, and an extrusion ball being movably embedded in the end of the mounting block away from the inner rod.

[0007] In the above-mentioned wire harness tape winding device, while the wire harness moves axially and is being wound, a uniform radial pressure is applied to the newly wound tape using an annularly arranged elastic extrusion component. This helps to minimize the entrainment of air between tape layers, promotes a tighter fit between the tape and the wire harness surface, and provides the possibility of enhancing adhesive adhesion, improving winding smoothness, and reducing the risk of bubbling or loosening during subsequent use.

[0008] As a further supplement to this application, multiple extrusion components are arranged in a ring array around the receiving hole, and the adjusting ring is coaxially arranged with the receiving hole.

[0009] As a further supplement to this application, the cross-section of the card plate is L-shaped, and the two card plates are mirror images of each other, with the threads at the front and rear ends of the screw rotating in opposite directions.

[0010] As a further supplement to this application, two support components are also fixedly connected to the upper end of the base plate. The two support components are located on the left and right sides of the support plate, respectively. Each support component includes a positioning block fixedly connected to the upper end of the base plate. A support seat is fixedly connected to the upper end of the positioning block, and a support wheel is rotatably connected inside the support seat.

[0011] As a further supplement to this application, the front and rear ends of the positioning block are fixedly connected with insert blocks, and the upper end of the support component is provided with a positioning rod, the lower end of which movably passes through the two insert blocks.

[0012] As a further supplement to this application, the longitudinal section of the positioning rod is an inverted U-shape, and the surface of the positioning rod is drilled with multiple insertion holes. Bolts are provided at the ends of the two insertion blocks that are far apart, and the bolt threads penetrate the insertion blocks and one of the insertion holes.

[0013] In summary, in practical applications, the wire harness is passed sequentially from right to left through the right support wheel, the receiving hole, and the left support wheel to center it. The tape roll is then mounted on the mounting plate, and the tape end is led out and fixed onto the wire harness. The motor drives the drive ring to rotate, causing the adjusting ring to rotate. As the wire harness moves slowly, the tape rotates with the adjusting ring, thus wrapping the tape around the wire harness. Immediately afterward, the wrapped wire harness passes through multiple compression balls in the receiving hole, where it is fully compressed under spring pressure, becoming tightly adhered. This promotes a closer bond between the tape and the wire harness surface, thereby enhancing adhesive adhesion, improving the smoothness of the wrapping, and reducing the risk of bubbling or loosening during subsequent use.

Detailed Implementation

[0025] The two embodiments of this application will be described in detail below with reference to the accompanying drawings.

[0026] First implementation method:

[0027] Figures 1-3 The diagram shows a wire harness tape winding device, comprising a base plate 1, a support plate 2 fixedly connected to the upper middle part of the base plate 1, a receiving hole 3 being drilled on the surface of the support plate 2, the receiving hole 3 being a channel through which the wire harness passes, and an adjusting ring 4 and a driving ring 5 being rotatably connected to the right end of the support plate 2, the adjusting ring 4 being coaxially arranged with the receiving hole 3, a motor 6 being fixedly connected to the left end of the support plate 2, the output end of the motor 6 being movably inserted through the support plate 2 and fixedly connected to the driving ring 5, the driving ring 5 and the adjusting ring 4 being jointly fitted with a belt 7, the motor 6 being started to drive the driving ring 5 to rotate, the rotation of the driving ring 5 driving the belt 7 to drive, thereby causing the adjusting ring 4 to rotate.

[0028] Figure 4 As shown: The right end of the adjusting ring 4 is rotatably connected to the mounting plate 8. The mounting plate 8 rotates together with the adjusting ring 4 and can be used as a tray for the tape roll. The right end of the mounting plate 8 has an adjusting groove 9. The inner cavity of the adjusting groove 9 is rotatably connected to the screw 10. The rear end of the screw 10 moves through the mounting plate 8, and the screw 10 is threaded with two clamping plates 11. The cross-section of the clamping plates 11 is L-shaped, and the two clamping plates 11 are mirror images of each other. The threads at the front and rear ends of the screw 10 turn in opposite directions. By rotating the screw 10, the distance between the two clamping plates 11 can be adjusted, thereby fixing tape rolls with different inner hole widths and facilitating tape roll replacement.

[0029] Figure 1 , Figure 5 and Figure 6 The diagram shows that multiple extrusion components are fixedly connected to the inner wall of the receiving hole 3. These components are arranged in a circular array around the receiving hole 3. The function of the extrusion components is to immediately roll and press the surface of the tape after it is wrapped. Each extrusion component includes an outer tube 12 fixedly connected to the inner wall of the receiving hole 3. A compression spring 13 is fixedly connected to the circular inner wall of the outer tube 12. An inner rod 14 is fixedly connected to the end of the compression spring 13 away from the inner wall of the receiving hole 3. A mounting block 15 is fixedly connected to the end of the inner rod 14 away from the compression spring 13. The mounting block 15 is located away from the inner rod. One end of the tube 14 is movably embedded with a compression ball 16. The outer tube 12 and the inner rod 14 form a guide telescopic rod, ensuring that the compression assembly can only extend and retract in a radial straight line. The compression spring 13 provides constant and adaptive radial pressure. The compression ball 16 rolls and crushes the tape through point contact. Multiple compression assemblies arranged in a ring array can automatically adapt to wire harnesses of different diameters under the action of the compression spring 13. The pressure expels the air in the tape, making it more tightly and firmly bonded to the wire harness and its own layers, significantly reducing bubbling and loosening during later use.

[0030] Figure 1 and Figure 7 As shown: Two support components are fixedly connected to the upper end of the base plate 1. The two support components are located on the left and right sides of the support plate 2 respectively. The support components include a positioning block 17 fixedly connected to the upper end of the base plate 1. A support seat 18 is fixedly connected to the upper end of the positioning block 17. The positioning block 17 is a hollow structure, and a cylinder is fixedly connected to the inner bottom wall of the positioning block 17. Those skilled in the art can select a suitable cylinder model according to actual needs, such as SCD50x100-100-LB. The extended end of the cylinder moves through the positioning block 17 and is fixedly connected to the lower end of the support seat 18. The height of the support seat 18 can be adjusted by the extension and retraction of the cylinder. A support wheel 19 is rotatably connected inside the support seat 18. The support components support and guide the wire harness on the left and right sides of the support plate 2, reducing its shaking and drooping during movement, effectively preventing the long wire harness from drooping due to its own weight or bending due to thrust, and making the wire harness pass straight through the receiving hole 3.

[0031] In use, the wire harness to be wound (indicated by point A in the figure) is first inserted into the device from the right side, passing through the right support wheel 19, the receiving hole 3 and the left support wheel 19 in sequence, so that the wire harness is in the center of the receiving hole 3. Then, the screw 10 is rotated in the forward direction, so that the two clamping plates 11 move towards the center of the screw 10 at the same time. Then, the tape roll (indicated by point B in the figure) is placed on the mounting plate 8, with the two clamping plates 11 located inside the tape roll. Then, the screw 10 is rotated in the reverse direction, so that the two clamping plates 11 move in opposite directions, thereby limiting and fixing the tape roll. Compared with the prior art, which directly uses a support rod without adjustment function, this application can fix tape rolls with different inner hole widths.

[0032] Next, a section of tape is extended and attached to the starting winding position of the wire harness. After the motor 6 is started, the power is transmitted to the adjusting ring 4 through the drive ring 5 and the belt 7, which drives the mounting plate 8 and the tape roll to revolve around the wire harness. At the same time, the wire harness moves at a constant speed from right to left along the axial direction (driven by other feeding mechanisms). The revolving tape roll then continuously and evenly winds the tape around the surface of the wire harness. This winding method is the winding method in the prior art.

[0033] After the wrapping is completed, the wire harness section covered with tape enters the receiving hole 3 stage. At this time, multiple extrusion components distributed in a ring array are driven by the continuous and adaptive radial pressure provided by the internal compression spring 13. The extrusion ball 16 applies uniform rolling pressure to the rotating wire harness surface. This process aims to effectively remove air that may be trapped between tape layers and at the interface between tape and wire harness during the wrapping process, promoting a tighter and stronger bond between the two. This application not only helps to enhance the adhesion of the tape and improve the surface flatness after wrapping, but also provides an effective process guarantee to reduce the risk of bubbling, curling, or even loosening of the finished product in subsequent handling, vibration, or temperature change environments.

[0034] Second implementation method:

[0035] This embodiment adds a plug block 20, a positioning rod 21, and a plug hole 22 to the first embodiment, while the rest remains the same as the first embodiment.

[0036] Figure 8 and Figure 9 As shown: the front and rear ends of the positioning block 17 are fixedly connected with the insertion blocks 20. The upper end of the support assembly is provided with a positioning rod 21. The lower end of the positioning rod 21 movably passes through the two insertion blocks 20. The longitudinal section of the positioning rod 21 is an inverted U-shape, and the surface of the positioning rod 21 is drilled with multiple insertion holes 22. The ends of the two insertion blocks 20 that are far apart are provided with bolts. The bolt threads pass through the insertion block 20 and one of the insertion holes 22.

[0037] During the movement of the wire harness, the upper end of the wire harness is limited by the positioning rod 21, thereby effectively reducing the possibility of the wire harness detaching from the support wheel 19 due to accidents. By selecting different insertion holes 22 to fix the positioning rod 21, the height of the positioning rod 21 can be adjusted to adapt to wire harnesses of different diameters and reduce the large-scale shaking of the wire harness during movement.

[0038] In light of current practical needs, the above-described embodiments adopted in this application are not limited to these. Any changes made within the scope of knowledge possessed by those skilled in the art without departing from the concept of this application still fall within the protection scope of this utility model.
