These application scenarios often come with higher requirements for power transmission efficiency and safety, especially under the impetus of high-power output and fast charging technologies, which pose more stringent challenges to the design of conductors. Specifically, in order to meet higher power transmission requirements, the number of strands and the cross-sectional area of the conductor must be increased accordingly to ensure sufficient current carrying capacity. At the same time, with the improvement of energy loss control and energy saving requirements, the full slot rate, dimensional accuracy, and long-term stability of the product have become important factors.

[0003] Under such a background, square-shaped wires (also known as shaped litz wires) have gradually become a popular choice in the market due to their unique shape and performance advantages. Square-shaped wires not only effectively improve the heat dissipation performance of conductors, reducing energy loss, but also better adapt to complex installation environments, improving the overall performance of products.

[0026] As shown in Figures 1-4 The embodiment provides a plurality of film-coated wire production device, including: wire mold 1 and leveling mechanism 2, the wire mold 1 and the leveling mechanism 2 are sequentially arranged along the wire direction, the wire mold 1 includes mold body 101, conical body 102 and wire outlet 103, the mold body 101 is hollow inside, the conical body 102 is coaxially arranged at the front end of the mold body 101, the conical body 102 is provided with a through hole penetrating through the front and back ends of the conical body 102, the wire outlet 103 is at least partially inserted into the through hole, the wire outlet 103 is provided with a wire outlet hole 1031 which is in the shape of a strip as a whole, and the two ends of the wire outlet hole 1031 along the length direction are in the shape of an arc, a plurality of wires 3 pass through the mold body 101, the conical body 102 and the wire outlet 103 in turn, and then pass out of the wire outlet hole 1031 to form a plurality of parallel wires 3, and the leveling mechanism 2 is used for leveling the wires 3 passing out of the wire outlet hole 1031; Wherein, the wire mold 1 and the leveling mechanism 2 are further provided with an automatic film wrapping mechanism, and the automatic film wrapping mechanism is used for winding a film on the wires 3 before the wires 3 enter the leveling mechanism 2.

[0027] Based on the above scheme, the working principle of the plurality of film-coated wire production device is as follows:

[0028] Wire 3 input: a plurality of wires 3 are first sent into the mold body 101 inside the wire mold 1, and the wires 3 are arranged in parallel in the mold body 101 to ensure the uniformity and consistency of subsequent processing.

[0029] Tapered transition and exit formation: The wire 3 then passes through the taper 102 and is arranged more closely within the gradually narrowing space. Next, the wire 3 passes through the exit portion 103, which is provided with an overall strip-shaped exit hole 1031, the two ends of which along the length direction are arc-shaped, helping the smooth transition of the wire 3, and when passing through the exit hole 1031, the wire 3 forms a stable multi-strand parallel wire 3, avoiding the uneven twisting problem that may occur in traditional twisted exit.

[0030] Film wrapping: After the wire 3 passes through the exit hole 1031 and maintains parallel arrangement, the automatic film wrapping equipment automatically wraps the film around it. At this stage, the insulating film or protective film is tightly wrapped around the wire 3. The film wrapping process ensures the insulation between the wires 3 and the stability of the overall structure.

[0031] Flattening treatment: The film-wrapped wire 3 then enters the flattening mechanism 2, which further flattens and straightens the wire 3 through a series of structures, ensuring the flatness and straightness of the wire 3, providing good conditions for subsequent installation and use.

[0032] Subsequent treatment: The flattened wire 3 also needs to go through cooling, solidification and other processing steps to ensure the firmness of the film wrapping and the overall performance of the wire 3. Finally, the required multi-film-wrapped wire product is obtained.

[0033] Overall, by adopting the parallel exit of multi-strand wire 3 and immediate film wrapping, the problems of twisting, stacking and uneven twisting of wire 3 in subsequent processing are avoided, thereby improving the quality and reliability of the product. The design of the exit portion 103 and the timely film wrapping ensure that the wire 3 can maintain a stable arrangement order when passing out, and effectively prevent the wire 3 from breaking and the film from breaking when the length-width ratio is large. The use of the flattening mechanism 2 ensures the flatness and straightness of the wire 3, providing good conditions for subsequent processing and use. In addition, the design of the device is flexible, and can be adjusted according to different wire 3 specifications and quantities, meeting the diversification and customization trends of market demand for square wire.

[0034] Further, the wire outlet mold 1 also comprises a protective sleeve 104, which is arranged at the front end of the tapered body 102 and wraps around the outer peripheral wall of the wire outlet portion 103. The protective sleeve 104 is arranged at the front end of the tapered body 102 and tightly wraps around the outer peripheral wall of the wire outlet portion 103. The main purpose of this design is to provide additional protection for the wire outlet portion 103 to prevent it from being damaged or worn during production. When the multiple wires 3 pass through the mold body 101 and the tapered body 102 and then pass out of the wire outlet hole 1031 of the wire outlet portion 103, the protective sleeve 104 plays a key protective role, effectively isolating external factors that may cause damage to the wire outlet portion 103, such as dust, impurities, moisture, mechanical impact, and high temperature, etc. These external factors not only may damage the structure of the wire outlet portion 103, but also may affect the arrangement of the wires 3 and the quality of the coating, thereby affecting the performance of the final product. The main function of the protective sleeve 104 is to prevent the wire outlet portion 103 from being damaged during production, ensuring that the shape and size of the wire outlet hole 1031 remain unchanged, thereby maintaining the stable arrangement of the wires 3 and the high-quality coating, which helps to improve the overall performance and reliability of the product.

[0035] It should be noted that the diameter of each wire 3 is d, the length of the wire outlet hole 1031 is L, the radius of the two ends of the wire outlet hole 1031 along its length direction is r, and the height of the wire outlet hole 1031 is h, where 3≤L / d≤8, L / d is an integer, 2r=h, and 90%≤d / 2r≤100%. The ratio of the length L of the wire outlet hole 1031 to the diameter d of the wire 3 is controlled within the range of 3≤L / d≤8, and L / d is an integer. This design aims to increase the aspect ratio of the multiple parallel wires 3 from the original maximum of 2:1 to 3:1 to 8:1. By increasing the aspect ratio, the problem of difficult twisting of a large number of wires and easy breaking of the wires can be solved. Especially when the aspect ratio is too large, the deformation of the wires 3 can be reduced, thereby avoiding the occurrence of quality problems such as square compression breaking and film breaking.

[0036] The relationship between the radius r of the two ends of the wire outlet hole 1031 and the height h is 2r=h, i.e. the two ends of the wire outlet hole 1031 along its length direction are circular or elliptical and equal to the height of the wire outlet hole 1031. This design ensures that the wires 3 can smoothly transition when passing out of the wire outlet hole 1031, avoiding the wires 3 being jammed or damaged due to shape mutation.

[0037] The ratio of the diameter d of the wire 3 to the radius r of the two ends of the wire outlet hole 1031 is controlled within the range of 90%≤d / 2r≤100%. This design means that the diameter of the wire 3 can be slightly smaller than or equal to the diameter of the two ends of the wire outlet hole 1031. This design facilitates the smooth passage of the wires 3 out of the wire outlet hole 1031 while maintaining a certain tension, ensuring the close arrangement and stable coating of the wires 3.

[0038] By optimizing the size design of the wire outlet hole 1031, especially increasing the aspect ratio, the multiple wires 3 can be more smoothly twisted, reducing the occurrence of quality problems such as wire breakage and film breakage, thereby improving the production efficiency. The equal design of the diameter and height of the wire outlet hole 1031 at both ends, as well as the reasonable proportion of the wire 3 diameter and the wire outlet hole 1031 radius, ensures the stability and safety of the wire 3 during the passing-out process, avoids the deformation and damage of the wire 3, and thus improves the overall performance and reliability of the final product.

[0039] In some embodiments, the flattening mechanism 2 includes a lead-in part 201, a mounting plate 202, and a plurality of pressure rollers 203. The lead-in part 201 is provided with a lead-in hole 2011 for the wire 3 to pass through. The mounting plate 202 is mounted on the side of the lead-in part 201 opposite the wire outlet die 1. The plurality of pressure rollers 203 are arranged on the mounting plate 202, and a flattening channel for the wire 3 to pass through is formed between the plurality of pressure rollers 203. The flattening mechanism 2 is mainly composed of the lead-in part 201, the mounting plate 202, and the plurality of pressure rollers 203. The lead-in part 201 is internally provided with a lead-in hole 2011 matched with the wire 3, for guiding the wire 3 to exit from the flattening mechanism 2 and enter the subsequent process. The mounting plate 202 serves as a stable support for the pressure rollers 203 and is mounted on the side of the lead-in part 201 opposite the wire outlet die 1, ensuring that the wire 3 can smoothly enter the flattening channel. The plurality of pressure rollers 203 are arranged on the mounting plate 202, and the flattening channel formed between them is the key to flattening the wire 3. The pressure rollers 203 precisely flatten the wire 3 by rolling and extruding, eliminating the bending, twisting, or unevenness that may occur during the transmission of the wire 3. This design not only significantly improves the straightness and surface quality of the wire 3, but also enhances the stability of production, reducing production failures and downtime caused by uneven wire 3. At the same time, the efficient operation of the flattening mechanism 2 also improves production efficiency and reduces production costs. By optimizing the structural design of the flattening mechanism 2, the wire 3 can pass through the flattening channel more smoothly, thereby ensuring the overall performance and product quality of the multiple film-coated wire production device.

[0040] Generally, a traction device is also provided for pulling the wire 3 from the wire outlet die 1 into the flattening mechanism 2 and then from the flattening mechanism 2 to the subsequent process.

[0041] Optionally, the pressure rollers 203 are arranged in a reverse triangular shape on the mounting plate 202. The unique arrangement of the three pressure rollers 203 in the leveling mechanism 2 not only ensures that the wire 3 receives uniform and stable pressure as it passes through the leveling channel, but also significantly improves the leveling effect. The reverse triangular arrangement allows each pressure roller 203 to level the wire 3 at the optimal angle and force, thereby eliminating any bending, twisting or unevenness that may occur during transmission.

[0042] In addition, the coordinated action of the three pressure rollers 203 also enhances the stability and reliability of the leveling mechanism 2. They collectively form a solid leveling channel that allows the wire 3 to maintain a stable transmission speed and direction when passing through, which not only improves production efficiency, but also reduces production costs, as production failures and downtime caused by uneven wire 3 are reduced.

[0043] In particular, the mold body 101 is provided with a plurality of mounting holes 1011. The mold body 101 of the wire outlet mold 1 is ingeniously provided with a plurality of mounting holes 1011, which not only facilitate the installation of the mold, but also ensure that the mold can be stably and accurately fixed on the corresponding structure. By using these mounting holes 1011, the operator can easily install the wire outlet mold 1 to the designated position on the production line, thereby ensuring that the wire 3 can accurately pass through the wire outlet hole 1031 and undergo subsequent leveling and film wrapping processing. The design of the mounting holes 1011 takes into account various factors, including the weight of the mold, the stress condition during work, and the cooperation accuracy with other components such as the leveling mechanism 2. Through reasonable layout and size design, the mounting holes 1011 can effectively disperse the stress and vibration generated by the mold during work, thereby improving the stability and service life of the mold.

[0044] At the same time, the installation of the mounting hole 1011 also provides great convenience for the maintenance and replacement of the mold. When cleaning the mold or replacing the wire outlet hole 1031 of different specifications, the operator only needs to simply remove the fixing screws, and can easily remove the mold from the production line, which not only saves maintenance time, but also reduces the operation difficulty and improves the overall production efficiency.

[0045] In some specific embodiments, the wire 3 processed by the multi-film-wrapped wire production device is of various types, including but not limited to film-wrapped wire, insulated wire and enameled wire. The common feature of these wires 3 is that they are all coated with an insulating layer on the outer surface, which is designed to provide electrical isolation and mechanical protection, ensuring the safety and reliability of the wire 3 during transmission and use.

[0046] Film-covered wire, as one of the important wire 3 types, its insulation layer is usually composed of one or more layers of thin film materials with good insulation performance and mechanical strength, which can effectively prevent current leakage and short circuit phenomenon.

[0047] Insulated wire refers to those wire 3 whose conductor surface is directly coated with insulation material. This wire 3 is widely used in various electrical equipment, instruments and meters for connecting and transmitting power or signals. The presence of the insulation layer not only provides electrical isolation, but also increases the mechanical strength of the wire 3 and improves its service life.

[0048] Enamelled stranded wire is a kind of wire 3 whose outer surface is coated with an insulating enamel layer. The insulating enamel layer not only has excellent insulation performance, but also provides protection against moisture, corrosion and wear. Enamelled stranded wire is widely used in the manufacture of windings for electrical equipment such as motors, transformers and electrical appliances.

[0049] In the production device of multiple film-covered wires, these wire 3s are processed by precise wire outlet mold 1 and flattening mechanism 2, which can maintain their original insulation performance and mechanical strength, and at the same time obtain better straightness and surface quality. This makes the final produced film-covered wire product have higher reliability and durability, which can meet various complex and demanding application requirements.

[0050] It is worth noting that the mold body 101, the conical body 102 and the wire outlet part 103 are integrally formed.

[0051] Generally, the flattening mechanism 2 is provided below the mounting frame 4. The mounting frame 4 is a support structure for the flattening mechanism 2, and its design and manufacture are crucial. It is made of high-strength, corrosion-resistant materials such as steel or aluminum alloy, etc. to ensure that it can withstand the weight and stress of the flattening mechanism 2 and the wire 3 it processes. The mounting frame 4 will be provided with fixing devices such as screw holes, clamping grooves or clamps that match the flattening mechanism 2, so as to firmly install the flattening mechanism 2 on the mounting frame 4. This not only ensures the stability of the flattening mechanism 2 during operation, but also facilitates its adjustment and maintenance.
