Description

Technical Field

[0001] This invention relates to wire wrapping, and more particularly to a wire wrapping device and a wire wrapping method. Background Technology

[0002] like Figure 1 and Figure 2 As shown, coaxial antenna wires often require partial wrapping with a single-sided adhesive textile fabric. These fabrics come in both conductive and non-conductive varieties. Current automated wire wrapping equipment, after wrapping, may experience some separation from the bonded area due to variations in the adhesiveness of the single-sided adhesive textile fabric. Figure 3 As shown, this is known in the industry as "explosion." This problem can occur with a certain probability within 1 to 6 months after the antenna is wrapped, and antennas that explode are considered defective.

[0003] A search revealed that application publication number CN113628813A discloses a wire wrapping device. The specific working process is as follows: the operator wraps the tape around a buffer wheel and the adhesive side of the tape onto the cable. Then, release paper is wound around a take-up wheel. The parameters of servo motors a and b are adjusted, and servo motors a and b are started, causing synchronous wheels a and b to rotate in opposite directions. When synchronous wheel a rotates, it drives the take-up wheel, unwinding device, and buffer device to rotate synchronously. However, this existing technology only achieves the synchronous unwinding of the tape and the winding of the release paper, suitable for large-area tape wrapping of cables, but cannot reliably wrap textiles around specific parts of the cable.

[0004] In summary, the technical problem that needs to be solved is how to design a wire wrapping device that can partially wrap cables with textile fabric and reduce the defect rate. Summary of the Invention

[0005] The purpose of this invention is to overcome the unreliability of partially wrapping antennas with textile fabric in the prior art by providing a wire wrapping device and a wire wrapping method.

[0006] The objective of this invention can be achieved through the following technical solutions:

[0007] According to one aspect of the present invention, a wire wrapping device is provided for wrapping a single-sided adhesive-coated textile fabric onto a cable. The device includes a conforming fixture, a heating element, and a wire wrapping assembly. The conforming fixture has a conforming groove on its surface, and a conforming wire groove on one side of the conforming groove. The textile fabric is placed in the conforming groove, and the cable is placed in the conforming wire groove. The heating element is disposed inside the conforming fixture. The wire wrapping assembly is located on the side of the conforming fixture with the conforming groove. The wire wrapping assembly includes a horizontally moving component and a vertically moving component connected to each other. The vertically moving component is close to the conforming fixture. The surface where the conforming groove is located is a first surface, and the direction perpendicular to the first surface is a first direction. The horizontally moving component moves along a direction parallel to the first surface and perpendicular to the cable, and the vertically moving component moves along the first direction.

[0008] As a preferred technical solution, the contouring component further includes a wire wrapping plate, which is mounted on the vertical moving part and parallel to the first surface.

[0009] As a preferred technical solution, the horizontal moving component is a linear motor.

[0010] As a preferred technical solution, the vertical moving component is a voice coil motor.

[0011] As a preferred technical solution, the device also includes a negative pressure generating device, and the contoured groove is provided with multiple vent holes, which are connected to the negative pressure generating device.

[0012] As a preferred technical solution, the axis of the cable is perpendicular to one edge of the textile fabric; the adhesive side of the textile fabric faces the winding assembly.

[0013] As a preferred technical solution, the device also includes an infrared temperature sensor located on one side of the conforming fixture to detect the temperature of the textile fabric.

[0014] As a preferred technical solution, the heating element provides a temperature range of 40 to 100°C.

[0015] As a preferred technical solution, the profiling fixture is a profiling fixture made of copper alloy.

[0016] According to another aspect of the present invention, a method for winding wire using a winding device is provided, specifically comprising the following steps:

[0017] Step S1: Place the textile fabric and cable inside the conforming fixture, and turn on the heating element to heat to the set temperature;

[0018] In step S2, the wrapping assembly moves toward the conforming fixture and applies a set pressure to the cable. The wrapping assembly moves in a direction perpendicular to the cable, pushing the cable to rotate, so that the textile fabric is wrapped around the cable.

[0019] Step S3: The heating element stops heating, and the wire wrapping assembly maintains pressure until the cable cools to room temperature;

[0020] Step S4: Move the wrapping assembly away from the cable and remove the fabric to complete the wrapping of the cable.

[0021] Compared with the prior art, the present invention has the following beneficial effects:

[0022] 1) This invention heats the wire and textile fabric within the conformal fixture using a heating tube. The wire wrapping assembly moves in two directions to pressurize the cable and wrap the textile fabric around the wire, achieving partial wrapping of the cable. The wrapping process involves heating, pressurizing, wrapping, and cooling the wire and the single-sided adhesive-coated textile fabric. The tiny air bubbles between the wire and the textile fabric are wetted by the heated and activated adhesive, improving the bonding effect between the wire and the textile fabric and greatly increasing the yield rate. Furthermore, the pressure is stopped only after cooling, allowing the adhesive to set and resulting in high dimensional consistency.

[0023] 2) This invention uses a negative pressure generating device and makes holes in the contour groove, which can make the textile fabric fit tightly in the contour groove, preventing unreliable application due to textile fabric movement; an infrared temperature sensor is set to detect the overall temperature of the textile fabric, making temperature control more accurate; the contour jig made of copper alloy has a low coefficient of thermal expansion and good thermal conductivity, which can heat up quickly, reduce time, and will not hinder the textile fabric from being wrapped on the cable.

[0039] 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 some, not all, of the embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort should fall within the scope of protection of the present invention.

[0040] Example 1

[0041] like Figure 1 As shown, this embodiment provides a wire wrapping device for wrapping a single-sided coated textile fabric 1 onto a cable 2, including a conforming jig 3, a heating tube 4, a wire wrapping assembly 5, an infrared temperature sensor 6, and a negative pressure generating device.

[0042] like Figure 2As shown, the contour jig 3 is rectangular in shape, with a contour groove 31 and a contour wire groove 32 on one side. The contour wire groove 32 is located next to the contour groove 31. The textile fabric 1 is placed in the contour groove 31, and the cable 2 is placed in the contour wire groove 32. The axis of the cable 2 is perpendicular to one edge of the textile fabric 1. The adhesive side of the textile fabric 1 faces the winding assembly 5. The contour groove 31 has multiple vent holes 311, which are connected to a negative pressure generating device. To ensure good thermal conductivity and a low coefficient of thermal expansion, the contour jig 3 is made of copper alloy.

[0043] like Figure 3 As shown, heating tubes 4 are evenly distributed within the conforming fixture 3 to heat the textile fabric 1. The temperature range provided by the heating tubes 4 is 40–100°C; the heating temperature can be adjusted according to the different types of adhesives applied to the textile fabric 1.

[0044] The wire wrapping assembly 5 is located above the contour jig 3. The wire wrapping assembly 5 includes a horizontal moving part, a vertical moving part, and a wire wrapping plate 53. The horizontal moving part can be a linear motor 51, which moves in a direction perpendicular to the cable 2. The vertical moving part can be a voice coil motor 52, which is mounted on the output end of the linear motor 51 and moves horizontally with the linear motor 51. The wire wrapping plate 53 is mounted parallel to the upper surface of the contour jig 3 on the output end of the voice coil motor 52 and moves vertically with the voice coil motor 52. That is, the wire wrapping plate 53 can move vertically and also move horizontally in a direction perpendicular to the cable 2.

[0045] Example 2

[0046] This embodiment provides a thread wrapping method, using the thread wrapping device in Embodiment 1, and the steps are as follows:

[0047] like Figure 4 and Figure 5 As shown, place the textile fabric 1 and cable 2 inside the contour jig 3 with the adhesive side of the textile fabric 1 facing upwards, and start the negative pressure generating device to make the textile fabric 1 adhere tightly to the contour jig 3.

[0048] like Figure 6 As shown, the heating element 4 is activated to heat the fabric, and the infrared temperature sensor 6 monitors the temperature of the textile fabric 1 in real time until the set temperature is reached.

[0049] like Figures 7-9 As shown, the wrapping assembly 5 moves down and applies a set pressure to the cable 2. The wrapping plate 53 moves in a direction perpendicular to the cable 2, and pushes the cable 2 to rotate by friction, so that the textile 1 is wrapped around the cable 2, completing the wrapping action. The heating tube 4 stops heating, and the wrapping assembly 5 maintains the current state and maintains the pressure until the cable 2 cools to room temperature (about 1 minute). During cooling, a cooling device can be set on the conforming fixture 3 or an air gun can be used for cooling.

[0050] like Figure 10 As shown, the wire wrapping assembly 5 is reset, and the textile fabric 1 is removed to wrap the cable 2.

[0051] The arrow in the diagram indicates the direction of movement of the wrapping component 5.

[0052] The above description is merely a specific embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any person skilled in the art can easily conceive of various equivalent modifications or substitutions within the technical scope disclosed in the present invention, and these modifications or substitutions should all be covered within the scope of protection of the present invention. Therefore, the scope of protection of the present invention should be determined by the scope of the claims.
