Its thickness is generally between 0.025mm and 2mm, its width is generally less than 5mm, and its width-to-thickness ratio ranges from 2:1 to 50:1. Copper flat wire has good thermal conductivity and electrical conductivity and is widely used in electrical, electronic, communication and construction fields. Compared with common round wire, copper flat wire has unique advantages in heat dissipation, welding contact area, fatigue resistance, hardness control and other aspects.

[0003] Copper flat wires need to be coated during production. Patent publication number CN201044191Y discloses a rolling device for the outer film of copper flat wires. The patent has two pairs of rollers arranged longitudinally and a pair of rollers arranged transversely. The wire has good guiding performance and uniform rolling. The rolled copper flat wires have good insulation and beautiful appearance.

[0004] However, the above patent still has the following problems in actual operation:

[0005] Due to technical limitations or improper operation, uneven coating is likely to occur, affecting the appearance and performance of the product. Some coating materials are difficult to form a good bond with the surface of the flat copper wire, causing the coating to easily fall off or break. Utility Model Content

DETAILED DESCRIPTION

[0021] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0022] In order to solve the problem of uneven coating due to technical limitations or improper operation, which affects the appearance and performance of the product, and some coating materials are difficult to form a good bond with the surface of the flat copper wire, resulting in the coating being easy to fall off or break, please refer to Figure 1-4 , this utility provides the following technical solutions:

[0023] A film wrapping device for non-woven film-wrapped soft flat copper wire comprises a base 1 and a flat copper wire 7. A cooling box 6 is arranged on the top of the base 1, a top plate 2 is arranged on one side of the cooling box 6, the top plate 2 and the base 1 are arranged horizontally and parallel, a heating box 3 is arranged between the top plate 2 and the base 1, a guide assembly 4 and a film coating roller 5 are arranged between the heating box 3 and the cooling box 6, a motor 8 is arranged on one side of the film coating roller 5, and the output shaft of the motor 8 is fixedly connected to the central shaft of the film coating roller 5. The flat copper wire 7 passes through the heating box 3, the guide assembly 4 and the film coating roller 5 in sequence and enters the interior of the cooling box 6 from one side of the cooling box 6, and the flat copper wire 7 passes through the other side of the cooling box 6.

[0024] In this embodiment, the guide assembly 4 is provided with two guide wheels 46, the outer part of the central axis of the guide wheel 46 is sleeved with a slider 44, and the side of the slider 44 away from the guide wheel 46 is provided with a fixing frame 41, the inner side of the fixing frame 41 is provided with a slide groove 42, the inner part of the slide groove 42 is provided with a slide bar 43, the slider 44 is slidably arranged on the slide bar 43, and the outer part of the slide bar 43 is surrounded by a spring 45, and the two guide wheels 46 are arranged in an upper and lower matching manner, and the fixing frames 41 on both sides of the two guide wheels 46 are respectively fixedly connected to the top plate 2 and the base 1 nearby. Through the arrangement of the two guide wheels 46, the guide assembly 4 can accurately control the position of the flat copper wire 7, which helps to ensure that the flat copper wire 7 will not deviate from the preset path during the coating process. The guide wheel 46 cooperates with the design of the slider 44, the slide bar 43 and the spring 45 to increase the stability of the flat copper wire 7 during the guiding process. When the flat copper wire 7 is subjected to external force or bending, the spring 45 can provide a certain resilience to keep its position stable. Since the guide wheels 46 are arranged in an upper and lower manner, the operator can more conveniently place the flat copper wire 7 between the guide wheels, which simplifies the operation process, helps to improve the efficiency of the coating process, and reduces errors or rework caused by unstable position.

[0025] In this embodiment, a heating chamber 31 is provided inside the heating box 3, and a spiral heating wire 32 is provided inside the heating chamber 31. The spiral heating wire 32 surrounds the interior of the heating chamber 31, and the spiral heating wire 32 surrounds the interior of the heating chamber 31. This design ensures uniform temperature distribution inside the heating box 3. This means that the flat copper wire 7 will be uniformly heat treated before entering the coating process, which helps to ensure the uniformity of its surface properties. Appropriate heating can soften or change the surface properties of the flat copper wire 7, making it easier to absorb subsequent coating materials. This not only improves the adhesion of the coating, but also helps to reduce bubbles or defects during the coating process.

[0026] In this embodiment, a cooling chamber 61 is provided inside the cooling box 6, and a wire inlet 62 and a wire outlet 63 are provided on both sides of the cooling box 6, respectively. A lower guide roller 64 and an upper guide roller 65 are provided inside the cooling chamber 61, and the flat copper wire 7 is wound around the lower guide roller 64 and the upper guide roller 65 in a "Z" shape from the wire inlet 62, and the flat copper wire 7 passes through the wire outlet 63. A cold air pipe 66 is provided inside the cooling chamber 61, and there are no less than four cold air pipes 66, and the four cold air pipes 66 are respectively arranged around each surface of the "Z"-shaped flat copper wire 7. The purpose of the cooling chamber 61 is to provide a closed space for the flat copper wire 7 for effective cooling, and to ensure that the cooling gas (such as the cold air provided by the cold air pipe 66) is uniformly around the flat copper wire 7 to enhance the cooling effect. The lower guide roller 64 and the upper guide roller 65 guide the flat copper wire 7 to bypass in a "Z"-shaped path, which can increase the contact area between the flat copper wire 7 and the cold air pipe 66, thereby improving the cooling efficiency. The surrounding cooling air pipes 66 can ensure that all sides of the flat copper wire 7 can be effectively cooled. More cooling air pipes 66 mean a stronger cooling effect, which helps to improve production efficiency and product quality.

[0027] The working principle of the above content is as follows: the flat copper wire 7 first enters the heating box 3, and the heat provided by the spiral heating wire 32 heats the flat copper wire 7 to prepare for its subsequent coating process. The flat copper wire 7 then passes through the guide assembly 4, and the two guide wheels 46 accurately clamp and guide the flat copper wire 7 to the correct position. The structure composed of the slider 44, the slide rod 43 and the spring 45 ensures the stability and accuracy of the flat copper wire 7 during the guiding process. The flat copper wire 7 then reaches the coating roller 5, and the coating roller 5 uses its outer film to tightly wrap the flat copper wire. At the same time, the motor 8 drives the coating roller 5 to rotate so that the film is evenly wrapped on the flat copper wire 7. The coated flat copper wire 7 enters the cooling box 6, where it is quickly cooled by the cold air provided by the cold air pipe 66. This rapid cooling can ensure that the coating layer is tightly combined with the flat copper wire and reduce any potential thermal stress. The cooled flat copper wire 7 passes through the other side of the cooling box 6 to complete the entire film coating process.
