Technical Field

[0001] This invention relates to the technical field of coating devices for thickening enamel films, and particularly to a coating device and method for thickening enamel films on enameled wires. Background Technology

[0002] In the application field of inductor products, especially in vehicle-related electronic systems, the performance and reliability of inductor products are crucial. As the automotive industry rapidly develops towards intelligence and electrification, vehicle electronic systems are becoming increasingly complex, placing higher demands on the quality and stability of inductor products.

[0003] In existing technologies, short circuits between coil layers within inductor products are a prominent problem. The main cause of these short circuits is powder breakdown of the enameled wire surface layer. This phenomenon leads to electrical failure and potentially serious consequences. Research has shown that increasing the thickness of the enameled wire surface layer can effectively reduce the possibility of powder breakdown during coil forming, thereby reducing short circuits between coils. However, during the thickening process of existing enameled wire coatings, the coating material cannot fully integrate with the original enamel layer, resulting in air bubbles between the thickened coating and the original coating, causing uneven insulation and affecting the electrical performance of the enameled wire. Therefore, improvements are necessary. Summary of the Invention

[0015] The above-mentioned technical objective of the present invention is achieved through the following technical solution: a method for thickening the enamel film of enameled wire, using an enameled wire enamel film thickening coating device as described in any of the above technical solutions; comprising:

[0016] Step 1: The enameled wire is reciprocated between the take-up assembly and the pay-off assembly. During the enameled wire feeding process, the screw adjustment assembly adjusts the height of the take-up assembly and the pay-off assembly relative to the base to keep the feeding direction of the enameled wire constant.

[0017] Step 2: During the conveying process, the enameled wire passes through the cleaning component to clean impurities on the surface of the enameled wire, the heating component to soften the surface enamel layer of the enameled wire, and the coating component to coat the surface of the enameled wire with a layer of enamel.

[0018] Step 3: After coating, the enameled wire is processed by a finishing component. The finishing component uses a scraping method to finish the coating layer on the outside of the enameled wire and control the coating thickness.

[0019] Step 4: After being processed, the enameled wire is dried by the drying assembly to dry the thickened enamel layer. The dried enameled wire is then stored by the winding assembly.

[0020] In summary, the present invention has the following beneficial effects:

[0021] 1. A cleaning component and a heating component are sequentially arranged along the conveying direction of the enameled wire. The cleaning component removes impurities from the surface of the enameled wire, thus preventing impurities from mixing into the thickened paint layer and causing air bubbles. The heating component heats the surface of the enameled wire to soften the surface paint layer, thereby improving the bonding effect of the thick paint layer. A finishing component is set in the middle of the base. The finishing component has a conical finishing seat on the base and several hollow air rings along the conveying direction of the enameled wire. The hollow air rings are inflated by air, causing the air film to expand. At this time, the painted enameled wire passes through the central hole of the hollow air ring. The thickened paint layer of the enameled wire is scraped through the central hole, thereby finishing the thickened coating to make the thickness of the thickened coating uniform and increase the bonding effect with the original paint film.

[0022] 2. A retaining ring is attached to the center of the inner membrane of the inflatable membrane, and the retaining ring is connected to the conical sorting seat based on several non-extendable connecting lines. When air is inflated into the inflatable membrane, the diameter of the central hole of the hollow inflatable ring is always equal, thereby achieving precise control of the thickness of the paint film in a single thickening. By setting multiple sets of hollow inflatable rings and setting the diameter of the central hole of the hollow inflatable ring to gradually decrease along the conveying direction of the enameled wire, the outer paint film of the enameled wire can be thickened multiple times by controlling the inflation sequence of the hollow inflatable rings, and the thickness of each thickening can be ensured to be uniform, further ensuring the uniformity of the paint film of the enameled wire, and also facilitating precise control of the paint film thickness.

[0023] 3. A monitoring component coupled to the lead screw lifting component is installed between the take-up component, the pay-off component, and the cleaning component. By monitoring the pressure of the enameled wire acting on the monitoring wheel, the two ends of the enameled wire are precisely controlled to be on the same straight line along the conveying direction, and the central axis of the enameled wire and the hollow air ring are always on the same straight line, thereby ensuring the uniformity of the thickened enamel film of the enameled wire.

The cleaning assembly 5, heating assembly 6, coating assembly 7, and coating assembly 9 are arranged in a symmetrical manner to control the thickness of the enamel film. The central axes of the drying component 8 and the cleaning component 8 are both located on the same horizontal straight line. The cleaning component 5 and the heating component 6 are arranged sequentially along the conveying direction of the enameled wire. The cleaning component 5 cleans the impurities on the surface of the enameled wire, thereby preventing impurities from being mixed in the thickened paint layer of the enameled wire and causing bubbles. The heating component 6 heats the surface layer of the enameled wire to soften the surface paint layer of the enameled wire, thereby improving the bonding effect of the thick paint layer. After being heated, the enameled wire passes through the coating component 7 to spray a layer of paint film on the outside of the enameled wire. Then, the enameled wire passes through the finishing component 9 to finish the thickness of the paint film. Finally, the enameled wire passes through the drying component 8 to dry and is then wound up. A monitoring component 10 is provided between the take-up assembly 3, the release assembly 4, and the cleaning assembly 5 to ensure that the enameled wire is always conveyed along the center line of the conical sorting seat 91. The monitoring component 10 is coupled to the lead screw lifting assembly 2. The monitoring component 10 includes a monitoring seat 101 fixedly connected to the base 1 and a monitoring wheel 102 rotatably connected to the monitoring seat 101. A pressure monitoring sensor 103 is provided between the monitoring seat 101 and the monitoring wheel 102. By monitoring the pressure of the enameled wire acting on the monitoring wheel 102, the sensor accurately controls the two ends of the enameled wire to be on the same straight line along the conveying direction, and ensures that the enameled wire and the center axis of the sorting assembly 9 are always on the same straight line, thereby ensuring the uniformity of the thickened coating of the enameled wire.

The lead screw drive motor 24 drives the lifting lead screw 23 to rotate, which in turn drives the lifting seat 22 to rise and fall on the lead screw seat 21. The take-up assembly 3 and the pay-off assembly 4 have the same structure, both including a wire roller 31 rotatably connected to the lifting base 22 and a take-up / pay-off motor 32 fixedly connected to the lifting base 22 to drive the wire roller 31 to rotate to achieve take-up or pay-off. The take-up assembly 3 and the pay-off assembly 4 are interchangeable. Take-up or pay-off can be achieved by controlling the rotation direction of the take-up / pay-off motor 32. The enameled wire is transported back and forth between the take-up assembly 3 and the pay-off assembly 4 to achieve multiple thickening of the enamel film, which improves the uniformity of the thickened enamel film and further enhances the bonding effect between the enamel films.
