[0034] The limitations of various nouns or methods referred to in the following embodiments, except for those that are logically untenable, are generally based on the broad concepts that can be implemented under the premise of the disclosure in the embodiments. Under such understanding, the various specific subordinate specific limitations of the nouns or methods should be regarded as the inventive content of the present invention, and should not be understood narrowly or interpreted in a biased manner on the grounds that the specification does not disclose the specific limitations. Similarly, under the premise that it can be implemented logically, the order of the steps in the method is flexible and changeable, and the specific subordinate specific limitations in the broad concepts of various nouns or methods all fall within the scope of protection of the present invention.

[0035] The main solution of the embodiment of the present application is: after multiple processes such as material selection, cleaning, painting and baking, an aluminum rod wire with a preset aluminum content is selected as a base material to ensure that the electrical performance of the produced enameled aluminum round wire is better, and after selection, the surface oil and impurities of the aluminum rod wire are cleaned, and then the cleaned aluminum rod wire is coated with an insulating paint liquid with a preset paint film thickness, wherein the insulating paint liquid is a combined paint liquid, so that the paint film has high adhesion and good wear resistance and voltage resistance, and finally the aluminum rod wire coated with the insulating paint liquid is baked to generate a paint film with insulating properties on the surface of the aluminum rod wire.

[0036] The existing enameled aluminum round wire has been widely used in the electrical industry. Due to the advantages of aluminum material such as light weight, good electrical conductivity and low cost, enameled aluminum round wire has gradually become the preferred material to replace traditional enameled copper round wire in many fields. However, the mechanical strength, electrical properties and heat resistance of aluminum are not as good as those of copper, and cannot meet the requirements of thermal shock performance of enameled wire.

[0037] The present application provides a solution to improve the mechanical strength, electrical properties and heat resistance of enameled aluminum round wire, thereby meeting the demand for high-performance enameled wire in modern electronic and electrical equipment.

[0038] Reference Figure 1 In one embodiment of the present invention, the production process of the enameled wire includes steps S100-S400, wherein:

[0039] S100, material selection: selecting aluminum rod wire with a preset aluminum content as the base material;

[0040] S200, cleaning: clean the surface oil and impurities of aluminum rod wire;

[0041] S300, painting: coating the cleaned aluminum rod wire with insulating paint liquid of preset paint film thickness;

[0042] S400, baking: baking the aluminum rod wire coated with the insulating paint liquid to form a paint film with insulating properties on the surface of the aluminum rod wire.

[0043] In this embodiment, in order to improve the electrical performance of the enameled wire, optionally, the aluminum content is preset to be greater than or equal to 99.7%, and the resistance loss during the conduction process is reduced by improving the purity of the aluminum rod wire.

[0044] Optionally, the cross-sectional diameter of the aluminum rod wire is 0.85 mm.

[0045] In this embodiment, the aluminum rod wire undergoes a series of processing steps to ensure that it has excellent electrical conductivity and mechanical strength. First, the aluminum rod wire undergoes multiple cold drawing processes during the drawing process to achieve the required small diameter. After each drawing, the aluminum rod wire is annealed to eliminate work hardening and restore its ductility. During the annealing process, the aluminum rod wire is heated to an appropriate temperature range, usually between 300°C and 500°C, maintained for a period of time, and then slowly cooled. This process helps to eliminate residual stress inside the material and improve its electrical conductivity. In order to improve the performance of the aluminum rod wire, surface treatments such as electroplating or coating with a protective film or adding lubricating oil can also be performed to prevent oxidation and corrosion.

[0046] Aluminum rods and wires are widely used in power transmission, electronic equipment, communication cables and other fields. Aluminum rods and wires play an important role in these fields due to their advantages such as light weight, high conductivity and good corrosion resistance. Especially in the field of power transmission, aluminum rods and wires have become an ideal substitute for copper wires due to their lower density and cost.

[0047] In this embodiment, during the cleaning process, a harmless cleaning method and a closed circulation system are used to reduce pollution to the environment, and the waste gas generated during the baking process is efficiently purified to ensure that the emissions meet environmental protection standards.

[0048] In this embodiment, the rotating speed of the painting equipment and the viscosity of the paint liquid are precisely controlled so that the insulating paint is evenly covered on the surface of the aluminum rod wire, ensuring that the paint film is uniform and free of bubbles. The baking process can adopt a multi-stage baking process to ensure that the paint film is gradually cured at different temperatures, thereby obtaining the best insulation performance and mechanical strength.

[0049] By optimizing the structural design of the painting equipment, the phenomenon of dripping or uneven thickness of the paint during the coating process can be effectively avoided, thereby improving production efficiency and product quality. Among them, the painting equipment includes a paint supply component and a paint coating component. The paint supply component is used to supply constant temperature and pressure paint to the paint coating component. The paint coating component determines the number of paint coats for the aluminum rod wire according to the preset paint film thickness.

[0050] Optionally, the painting component uses a mold for painting, and the painting component determines the mold size according to a preset paint film thickness.

[0051] In this embodiment, the mold is processed by a high-precision CNC machine tool to ensure its dimensional accuracy and surface finish. The inner wall of the mold can be coated with a special release agent to ensure that the painted component can be removed smoothly and avoid damage to the paint film. Before painting, the aluminum rod wire is thoroughly cleaned and degreased through a cleaning step to ensure the adhesion of the paint film to the surface of the component. Next, the treated aluminum rod wire is placed in the mold to ensure that its position is accurate. Then, the formulated paint is injected into the mold, and the paint is evenly distributed in the mold to ensure a consistent thickness of the paint film.

[0052] In order to improve the efficiency and quality of painting, automated painting equipment is used. The equipment accurately controls the injection speed and time of the paint to ensure that the paint is evenly distributed in the mold to avoid bubbles and sagging. After painting, the mold is placed in an oven for curing. By accurately controlling the baking temperature and time, the paint film can be effectively prevented from cracking or falling off at high temperatures, ensuring the integrity and adhesion of the paint film.

[0053] Optionally, the material of the insulating paint is polyesterimide, polyamideimide and self-lubricating polyamideimide, and the insulating paint liquid includes a primer and a topcoat.

[0054] In this embodiment, the insulating varnish is widely used in the insulation treatment of windings of electrical equipment such as motors, transformers, capacitors, etc. Its excellent electrical properties, heat resistance and mechanical strength make it an indispensable part of the modern electronics industry. By mixing polyesterimide, polyamideimide and self-lubricating polyamideimide in a predetermined ratio, insulating varnishes with different properties can be prepared. For example, polyesterimide paint has good heat resistance and mechanical strength, and is suitable for electrical equipment in high temperature environments. Polyamideimide paint has excellent chemical resistance and flexibility, and is suitable for occasions that require frequent bending or exposure to chemicals.

[0055] In the process of preparing insulating varnish, the selected resin material needs to be mixed evenly with the solvent, curing agent and other additives. During the mixing process, the temperature and stirring speed must be strictly controlled to ensure that the resin is fully dissolved and evenly dispersed. Subsequently, the mixed paint liquid is filtered to remove possible impurities and particles to ensure the purity of the paint liquid and the coating quality. In addition to the polyesterimide, polyamideimide and self-lubricating polyamideimide mentioned above, the materials of insulating varnish can also include epoxy resin, silicone resin, etc.

[0056] In practical applications, the construction process of insulating paint is also very important. Generally, the main function of the primer is to improve the adhesion between the insulating paint and the wire, while the topcoat plays a role in protection and insulation. The primer and topcoat can be applied by spraying, dipping or brushing. In order to ensure the uniformity and thickness of the paint film, the temperature, humidity and drying time need to be strictly controlled during the construction process.

[0057] In addition, the performance of insulating paint is closely related to its curing conditions. For example, polyamide-imide paint needs to be baked at a temperature of 150°C to 180°C for several hours during the curing process to ensure that the paint film is fully cured. Epoxy resin paint may need to be cured at a higher temperature, and the specific curing conditions depend on the type of resin and curing agent selected.

[0058] In this embodiment, after multiple processes such as material selection, cleaning, painting and baking, an aluminum rod wire with a preset aluminum content is selected as a base material to ensure that the produced enameled aluminum round wire has better electrical properties. After the selection, the surface oil and impurities of the aluminum rod wire are cleaned, and then the cleaned aluminum rod wire is coated with an insulating paint liquid with a preset paint film thickness, wherein the insulating paint liquid is a combined paint liquid, so that the paint film has high adhesion, good wear resistance and voltage resistance, and finally the aluminum rod wire coated with the insulating paint liquid is baked to generate a paint film with insulating properties on the surface of the aluminum rod wire, so as to improve the mechanical strength, electrical properties and heat resistance of the enameled aluminum round wire, thereby meeting the demand for high-performance enameled wire in modern electronic and electrical equipment.

[0059] The enameled wire produced by the production process method adopted in this embodiment has better performance than the national standard and domestic similar products, as follows:

[0060]

[0061] Optionally, refer to Figure 2 Another embodiment of the present invention provides a production process for enameled wire, based on the above Figure 1 In the embodiment shown, cleaning: the step of cleaning the surface oil and impurities of the aluminum rod wire is specifically step S210, wherein:

[0062] S210, based on ultrasonic vibration and water boiling process, cleans the surface oil and impurities of aluminum rod and wire.

[0063] In this embodiment, an efficient and environmentally friendly cleaning method is used, where the aluminum rod wire is immersed in an aqueous solution containing a specific proportion of a cleaning agent, and then an ultrasonic generator is activated to generate high-frequency vibration waves. These vibration waves can penetrate into the tiny gaps of the aluminum rod wire and shake off the oil and impurities attached to the surface. At the same time, the boiling process can accelerate the dissolution of oil and the detachment of impurities by heating the cleaning solution.

[0064] During the cleaning process, the control of temperature and ultrasonic frequency is crucial. Too high a temperature may damage the surface of the aluminum rod and wire, while too low a temperature will affect the cleaning effect. In addition, the ultrasonic frequency also needs to be adjusted according to the type and degree of contamination of the aluminum rod and wire to achieve the best cleaning effect.

[0065] After cleaning, the rinsed aluminum rod and wire can be centrifuged to remove surface moisture. Finally, the aluminum rod and wire are sent to the drying room for drying to ensure that the surface is completely dry to avoid rust or contamination in subsequent processes.

[0066] Through the above steps, the surface oil and impurities of the aluminum rod wire are completely removed, providing high-quality raw materials for subsequent processing steps. This cleaning method not only improves production efficiency, but also reduces environmental pollution, improves the mechanical strength, electrical properties and heat resistance of the enameled aluminum round wire, thereby meeting the demand for high-performance enameled wire in modern electronic and electrical equipment.

[0067] Optionally, refer to Figure 3 Another embodiment of the present invention provides a production process for enameled wire, based on the above Figure 1 In the embodiment shown, painting: coating the cleaned aluminum rod wire with insulating paint liquid having a preset paint film thickness includes step S310, wherein:

[0068] S310, applying primer and topcoat to the cleaned aluminum rod wire in sequence.

[0069] In this embodiment, a special double-layer coating process is used to ensure that the insulation performance of the aluminum rod wire is optimal. First, the cleaned aluminum rod wire is dried to ensure that there is no residual moisture on the surface. Then, the primer is applied. The main function of the primer is to enhance the adhesion between the aluminum rod wire and the topcoat, while providing a certain degree of corrosion protection.

[0070] After the primer is applied, it needs to be dried for a period of time to ensure that it is fully cured. Then, the topcoat is applied. The topcoat not only has an insulating function, but also provides an additional protective layer to resist the erosion of the external environment. When applying the topcoat, advanced coating equipment is used to ensure that the paint film is uniform and free of bubbles, thereby ensuring the final insulation effect.

[0071] After coating, the aluminum rod wire needs to enter the baking oven for curing. The baking temperature and time need to be strictly controlled to ensure that the paint film is completely cured and reaches the mechanical strength and electrical properties required by the design. After curing, the aluminum rod wire will be cooled to avoid cracking or deformation of the paint film caused by a sudden drop in temperature.

[0072] After the above process, the aluminum rod wire not only has excellent insulation performance, but also has good weather resistance and anti-aging ability. The final product will meet the use requirements in various harsh environments and provide reliable guarantee for power transmission. By optimizing the coating process and strictly controlling the production process, the comprehensive performance of the enameled wire is significantly improved, providing high-quality insulation products.

[0073] Optionally, refer to Figure 4 Another embodiment of the present invention provides a production process for enameled wire, based on the above Figure 1 In the embodiment shown, after the step of painting: coating the cleaned aluminum rod wire with insulating paint liquid having a preset paint film thickness, the production process further comprises step S500, wherein:

[0074] S500, apply surface lubricant on the outer layer of topcoat.

[0075] In this embodiment, the outer layer of the topcoat is coated with a surface lubricant for lubrication, so that when the enameled wire is used for winding, friction can be effectively reduced and damage to the paint film can be avoided. In order to ensure the uniform distribution of the lubricant, the aluminum rod wire can pass through a vibration platform during the coating process. The vibration platform forms a uniform film of lubricant on the surface of the aluminum rod wire through small and rapid vibrations. In addition, the vibration platform can also help eliminate bubbles on the surface, ensure the close combination of the lubricant and the aluminum rod wire, and ensure that it forms a uniform, thin and transparent protective film on the surface of the enameled wire. This protective film can not only provide a lubricating effect, but also improve the heat resistance and chemical resistance of the enameled wire to a certain extent.

[0076] After the surface lubricant is applied, it is necessary to dry it. The purpose of drying is to quickly solidify the surface lubricant and form a stable protective layer. The drying temperature and time need to be precisely controlled according to the type of lubricant selected to ensure its performance is optimal. During the drying process, it is also necessary to prevent the surface of the enameled wire from overheating or local overheating, so as not to affect its electrical performance and mechanical strength.

[0077] Optionally, refer to Figure 5 Another embodiment of the present invention provides a production process for enameled wire, based on the above Figure 1 In the embodiment shown, after the step of baking: baking the aluminum rod wire coated with the insulating paint liquid to form a paint film with insulating properties on the surface of the aluminum rod wire, the production process further includes step S600, wherein:

[0078] S600, Inspection: Use inspection equipment to inspect the painted aluminum rod wire. When the defects exceed the preset quality standards, the inspection equipment will issue an alarm.

[0079] Among them, the preset quality standards include defects such as oxidation, burrs and cracks.

[0080] In this embodiment, the quality inspection includes multiple items such as appearance inspection, thickness measurement, adhesion test, heat resistance test, etc. The appearance inspection mainly observes whether the surface of the enameled wire is smooth and has no obvious defects; the thickness measurement ensures that the thickness of the paint film and the lubricant layer meets the standard requirements; the adhesion test is used to evaluate the bonding strength between the paint film and the aluminum rod wire; the heat resistance test checks whether the enameled wire can maintain good insulation performance in a high temperature environment.

[0081] The present invention also provides an enameled round aluminum wire, which is manufactured by adopting the above enameled wire production process.

[0082] It is worth noting that since the enameled aluminum round wire of the present invention is based on the above-mentioned production process of the enameled wire, the embodiments of the enameled aluminum round wire of the present invention include all technical solutions of all embodiments of the above-mentioned production process of the enameled wire, and the technical effects achieved are also exactly the same, which will not be repeated here.
