Technical Field
[0001] This utility model relates to the field of high-frequency transformer processing technology, and specifically to a paint baking device for high-frequency transformer processing. Background Technology
[0002] With social development and progress, electricity has become an indispensable energy source in life. As living standards improve, electrical equipment is developing rapidly. High-frequency transformers, the heart of electrical appliances, are mainly used in high-frequency switching power supplies. During the manufacturing process of high-frequency transformers, they require painting, followed by drying the painted surface.
[0003] In the prior art, a Chinese patent document with publication number CN222035585U and publication date of November 22, 2024, was proposed to solve the above-mentioned technical problems. The technical solution disclosed in this patent document is as follows: An environmentally friendly transformer processing paint baking device includes a fixed plate, a pad fixedly installed at the bottom of the fixed plate, a processing chamber fixedly installed at the top of the fixed plate, and a drying assembly disposed on the side wall of the fixed plate. The drying assembly includes a drying mechanism installed on the side wall of the fixed plate, the drying mechanism being located on the inner wall of the processing chamber. A processing mechanism is installed at the top of the fixed plate, the processing mechanism being located on the side wall of the processing chamber. There are four pads, and the four pads are all of equal shape and size.
[0004] To address the issue of uniform transformer drying, existing technology employs a motor-driven turntable rotation, which in turn causes the transformer on the turntable to rotate. However, if the paint on the transformer surface is not yet dry, centrifugal force will be generated during the turntable rotation. Due to insufficient adhesion, the undried paint will be thrown off the transformer surface, resulting in uneven paint layer thickness and localized paint evaporation problems. Utility Model Content
[0005] The purpose of this invention is to provide a baking paint device for high-frequency transformer processing, so as to solve the problems mentioned in the background art.
[0006] To solve the above-mentioned technical problems, the technical solution adopted by this utility model is as follows:
[0007] A high-frequency transformer processing painting device includes a painting box, the painting box including a box shell, a protective cover fixedly installed on the top of the box shell, and a bracket fixedly installed on the upper right side of the box shell.
[0008] The top of the housing is provided with a rotating groove, and a turntable is rotatably connected inside the rotating groove. A driven gear is fixedly installed on the top of the turntable.

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0025] Example 1
[0026] like Figure 1-5 As shown, this utility model provides a high-frequency transformer processing painting device, including a painting box 1, which includes a box shell 2. A protective cover 3 is fixedly installed on the top of the box shell 2. A bracket 213 is fixedly installed on the right side of the box shell 2. A rotating groove 28 is opened on the top of the box shell 2. A turntable 29 is rotatably connected inside the rotating groove 28. A driven gear 210 is fixedly installed on the top of the turntable 29. A connecting frame 211 is fixedly installed on both sides of the bottom end of the turntable 29. An electric heating tube 212 is fixedly installed inside the connecting frame 211. A servo motor 214 is fixedly installed inside the bracket 213. A drive rod 215 is fixedly installed on the output end of the servo motor 214. The other end of the drive rod 215 extends inside the right side of the protective cover 3 and is fixedly sleeved with a drive gear 216. The drive gear 216 meshes with the driven gear 210.
[0027] Furthermore, after the servo motor 214 starts, it drives the drive rod 215 at the output end to rotate. The drive gear 216 at the other end of the drive rod 215 rotates accordingly. Since the drive gear 216 meshes with the driven gear 210, it drives the driven gear 210 to rotate. The driven gear 210 is fixed on the top of the turntable 29, which causes the turntable 29 to rotate slowly and uniformly in the rotating groove 28. The electric heating tube 212 rotates synchronously and heats the high-frequency transformer evenly, so that the paint gradually dries in a constant temperature environment to ensure uniform adhesion of the paint layer.
[0028] Example 2
[0029] like Figure 1-5 As shown, based on Embodiment 1, this utility model provides a technical solution: Preferably, a slot 21 is provided inside the front shell of the housing 2, and a sealing plate 22 is movably inserted into the slot 21. An abutment groove 23 is provided at the inner left end of the sealing plate 22. A slot 24 is provided inside the rear shell of the housing 2, and a sealing plate 25 is movably inserted into the slot 24. A slot 3 26 is provided inside the left shell of the housing 2, and a sealing plate 3 27 is movably inserted into the slot 3 26. The other end of the sealing plate 3 27 is inserted into the abutment groove 23.
[0030] Furthermore, the sealing plates 22, 25, and 27 are pushed in sequence to insert them into slots 21, 24, and 26 respectively. The other end of the sealing plate 27 is inserted into the abutment groove 23 of the sealing plate 22, forming a seal on the front, back, and left sides of the outer shell 2. This ensures that the interior of the paint box 1 is sealed, reducing heat loss, and also makes it easy to remove the transformer when it is opened.
[0031] The solution uses a PLC as the core control component. The PLC establishes a connection with the servo motor 214 and the electric heating tube 212 through RS-485 communication. When it is necessary to start the servo motor 214 and the electric heating tube 212, the PLC sends a start command to the servo motor 214 and the electric heating tube 212, causing the servo motor 214 and the electric heating tube 212 to start.
[0032] The working principle of the paint baking device for high-frequency transformer processing will be explained in detail below.
[0033] like Figure 1-5As shown, during use, the high-frequency transformer to be painted is placed inside the outer casing 2 of the enclosure. Then, the sealing plates 22, 25, and 27 are pushed in sequence, inserting them into slots 21, 24, and 26 respectively. The other end of the sealing plate 27 is inserted into the contact groove 23 of the sealing plate 22, forming a seal on the front, back, and left sides of the outer casing 2. This ensures a sealed space inside the painting enclosure 1, reducing heat loss. Simultaneously, it facilitates the removal of the transformer when opened. Servo motor 2... After 14 is started, it drives the drive rod 215 at the output end to rotate, and the drive gear 216 at the other end of the drive rod 215 rotates accordingly. Since the drive gear 216 is meshed with the driven gear 210, it drives the driven gear 210 to rotate. The driven gear 210 is fixed on the top of the turntable 29, which causes the turntable 29 to rotate slowly and uniformly in the rotating groove 28. The electric heating tube 212 rotates synchronously and heats the high-frequency transformer evenly, so that the paint gradually dries in a constant temperature environment to ensure uniform adhesion of the paint layer.
[0034] The present invention has been described in detail above. However, modifications or improvements can be made to it, which will be obvious to those skilled in the art. Therefore, any modifications or improvements that do not depart from the spirit of the present invention are within the protection scope of the present invention.
