Description

Technical Field

[0001] The present application relates to the technical field of high-frequency transformer accessory production, and specifically discloses an automatic baking device for high-frequency transformer production. Background Art

[0002] A high-frequency transformer is a key component in the field of power electronics. Its core function is to achieve voltage transformation and energy transfer through electromagnetic induction. The main core components are as follows: Windings: Primary winding: Connected to a high-frequency AC power supply to generate an alternating magnetic field; Secondary winding: Obtain energy through electromagnetic induction and output the target voltage; Materials and insulation: Usually wound with copper wire or aluminum wire, and the outer layer is isolated by paper insulation, yarn wrapping insulation or multi-layer insulation tape to ensure high-voltage and high-frequency characteristics; Magnetic core: Mostly made of high magnetic permeability materials such as ferrite, silicon steel sheet or amorphous alloy to reduce high-frequency eddy current loss and hysteresis loss; Auxiliary structures and components: Insulation and protection structures, cooling and heat dissipation systems, and regulation and protection devices; Regarding the magnetic core including a base and a magnetic film covering the surface of the base: The base refers to the basic structure of the magnetic core, that is, the skeleton or the magnetic core body that supports the winding. It is the carrier for winding the winding and participates in the formation of the magnetic circuit, affecting the magnetic performance and mechanical stability of the transformer; The magnetic film refers to a shielding material used on the surface of the magnetic core or winding. By guiding or absorbing the external magnetic field, it reduces the influence of strong magnetic interference on the transformer; Regarding the magnetic film covering the base: Physical bonding method and coating evaporation method, the common one is the coating evaporation method. At present, most of the magnetic films in the cutting-edge technology are liquid magnetic materials such as ferrite slurry or nano magnetic coating. The magnetic coating is evenly covered on the surface of the base by spraying, brushing or dipping, and then the evaporation curing is realized by using an automatic baking device, and then a continuous magnetic film is formed; At present, the existing problem is that the common baking method is hot air baking. The magnetic film formed by this hot air baking has obvious film thickness differences. Because there are different wind direction forces in hot air baking, the forces acting on the base and the obvious gravity influence on the liquid magnetic material lead to film thickness differences under various factors. When the film thickness is different, the performance of the magnetic core is different. In order to improve the performance of the magnetic core and the production quality stability of the magnetic core, the present application proposes an evaporation baking device with no clear wind direction as the core and dedicated to the baking of transformer magnetic cores. In view of this, the present application provides an automatic baking device for high-frequency transformer production to solve the above problems. Summary of the Invention

[0003] The purpose of the present invention is to solve the problem that there are obvious film thickness differences in the baking device for covering the magnetic film of the magnetic core used in traditional transformers.

[0004] To achieve the above object, the present invention provides the following basic solution: An automatic baking device for the production of high-frequency transformers, comprising an evaporation tank, a soaking tank, a baffle located at the internal connection of the evaporation tank and the soaking tank, a lifting drive assembly located on the evaporation tank, a lifting plate initially located in the soaking tank and connected to the lifting drive assembly, a plurality of substrate fixing members installed on the lifting plate for storing substrates and liquid magnetic materials, and a steam generating assembly located inside the evaporation tank near the baffle. After the end position of the lifting plate is connected to the baffle, the evaporation tank is in a sealed environment. The steam generated by the steam generating assembly acts around the substrate fixing members and does not contact the substrates in the substrate fixing members. The steam generated by the steam generating assembly heats the substrate fixing members, and the liquid magnetic material in the substrate fixing members slowly flows downward, and the outflow rate is less than the evaporation and curing rate of the liquid magnetic material.

[0005] Further, the evaporation tank and the soaking tank are integrally formed. A temperature control panel electrically connected to the steam generating assembly is provided on one side of the evaporation tank. A switch door is rotatably connected to the evaporation tank, and a handle is provided on the switch door. The soaking tank is used for the inlet and outlet of the liquid magnetic material. Liquid inlet pipes and drain pipes are respectively communicated on both sides of the soaking tank, and the height of the liquid inlet pipe is higher than the height of the drain pipe.

[0006] Further, a through groove is opened on the baffle. A clamping plate is installed on the lifting plate. The size of the clamping plate is smaller than the size of the lifting plate, and the size of the clamping plate is equal to the inner diameter of the through groove. The substrate fixing members are all installed on the clamping plate. After the lifting plate moves, the clamping plate passes through the through groove and is clamped by the lifting plate, and the lifting plate and the evaporation tank form a sealed environment.

[0007] Further, the substrate fixing member includes a base and a groove body installed on the base for storing the substrate. A functional block is provided inside the groove body. The groove body includes a clamping section and a liquid leakage section. The clamping section and the liquid leakage section are integrally formed. A first inclined surface is provided on the outer periphery of the functional block. A second inclined surface is provided on one side of the clamping section close to the first inclined surface. The first inclined surface and the second inclined surface are inclined in opposite directions. The bottom height of the liquid leakage section is lower than the bottom height of the clamping section. A plurality of liquid leakage holes are opened at the bottom of the liquid leakage section. After the substrate is placed, the first inclined surface cooperates with the second inclined surface to clamp both sides of the substrate, and the liquid leakage section does not contact the substrate. The height of the groove body is higher than the installation height of the substrate.

[0008] Further, the lifting drive assembly includes a top plate installed on the top of the evaporation tank, a plurality of connecting rods provided below the top plate, and a cylinder installed on the top of the evaporation tank below the top plate. One ends of the connecting rods are fixedly connected to the top plate, and the other ends of the connecting rods pass through the soaking tank and are connected to the lifting plate.

[0009] Furthermore, the steam generation assembly includes an external steam generator, a plurality of conduits connected to the output end of the steam generator, a steam output loop installed in the evaporation tank and communicated with the conduits, and a frame-shaped output steam duct communicated with the steam output loop. The frame-shaped output steam duct is formed with a plurality of output areas corresponding to the number and positions of the troughs one by one, and a plurality of hot air acting tubes are evenly arranged in the output areas.

[0010] Furthermore, the installation position of the steam output loop is in the same plane as the position where the lifting plate and the evaporation tank form a sealed environment.

[0011] Furthermore, the hot air acting tubes are arranged around the troughs. The ends of the hot air acting tubes are sealed and the hot air acting tubes are made of metal. The sealed ends of the hot air acting tubes are in contact with the troughs. Air outlet pipes are arranged on the hot air acting tubes near the sealed ends of the hot air acting tubes, and the air outlet directions of the air outlet pipes do not act on the troughs.

[0012] The principle and effect of this solution are as follows: 1. Compared with the prior art, this device is a special production device for the magnetic core in a high-voltage device. Specifically, it is a production device for the substrate and the magnetic film covering the surface of the substrate. This device adopts the evaporation baking principle to evaporate and solidify the liquid magnetic material such as ferrite slurry or nano magnetic coating on the surface of the substrate, thereby realizing the production of the magnetic core in the core component of the high-frequency transformer.

[0013] 2. Compared with the prior art, the core of this device is the evaporation baking using the evaporation method to realize the connection between the substrate and the liquid magnetic film, and then complete the production of the magnetic core in the high-voltage device. The first core is the co-existing evaporation baking of the substrate and the liquid magnetic material. After the traditional substrate and the liquid magnetic material are separated, the liquid magnetic material adhered to the substrate is evaporated and baked. Due to the self-gravity of the liquid magnetic material, there will be a problem of film thickness difference. This device adopts the synchronous evaporation baking of the substrate and the liquid magnetic material. The liquid magnetic material slowly flows out and cooperates with evaporation, thereby ensuring the uniform thickness of the liquid magnetic material on the substrate. 3. Compared with the prior art, the core of this device is the baking using the evaporation method to realize the connection between the substrate and the liquid magnetic film, and then complete the production of the magnetic core in the high-voltage device. The second core is the evaporation design without a clear evaporation wind direction or the evaporation design indirectly acting on the substrate. The traditional evaporation means uses evaporation hot air, and the evaporation hot air has a clear direction acting on the substrate, which leads to film thickness difference. Based on this, this device designs an evaporation device without a clear evaporation wind direction. This evaporation device only provides a large range of heat and does not provide a clear directional hot air, avoiding the problem of film thickness difference caused by the hot air acting on the substrate.

[0014] 4. Compared with the prior art, the core of this device is baking using the evaporation method to connect the substrate with the liquid magnetic film, thereby completing the production and manufacturing of the magnetic core in the production of high-voltage transformers. The third core is evaporation drying combined with metal heat conduction baking. Since the substrate fixture is made of metal, the hot air action tube acts directly on the substrate fixture and contacts it. According to the heat conduction characteristics of the metal, the substrate fixture is heated. Since there is liquid magnetic material inside the substrate fixture, the evaporation baking of the liquid magnetic material is thus achieved.

[0015] 5. Compared with the prior art, the core of this device is baking using the evaporation method to connect the substrate with the liquid magnetic film. The substrate fixture in this device is applicable to most different models of substrates, and can fix the substrate, and can ensure that the liquid magnetic material located inside the substrate fixture can slowly flow out to cooperate with evaporation, realizing the coverage of the magnetic film on the substrate.

[0018] In order to further illustrate the technical means and effects adopted by the present invention to achieve the predetermined purpose of the invention, the specific implementation methods, structures, features and effects of the present invention are described in detail below in conjunction with the accompanying drawings and preferred embodiments.

[0019] The figure marks in the drawings of the specification include: filter element 1, magnetic film 2, first winding 3, second winding 4, base 5, clamping section 6, leakage section 7, first inclined surface 8, second inclined surface 9, functional block 10, leakage hole 11, leakage surface 12, evaporation box 13, immersion box 14, liquid inlet pipe 15, liquid outlet pipe 16, baffle 17, lifting plate 18, clamping plate 19, steam output loop 20, connecting plate 21, frame-type steam output duct 22, ejector plate 23, connecting rod 24, cylinder 25, temperature control panel 26, conduit 27, switch door 28, handle 29, hot air action pipe 30, sealing end 31, air outlet pipe 32, trough body 33.

[0020] Implementation example Figure 1 、 Figure 2 、 Figure 3 、 Figure 4 、 Figure 5 、 Figure 6 、 Figure 7 、 Figure 8 and Figure 9 As shown: An automatic baking device for high-frequency transformer production includes an evaporation box 13, an immersion box 14, a baffle 17 located at the connection between the evaporation box 13 and the immersion box 14, a lifting drive assembly located on the evaporation box 13, a lifting plate 18 initially located in the immersion box 14 and connected to the lifting drive assembly, a plurality of substrate fixing members mounted on the lifting plate 18 for storing substrates and liquid magnetic materials, and a steam generating assembly located inside the evaporation box 13 and near the baffle 17. After the end position of the lifting plate 18 is connected to the baffle 17, the evaporation box 13 is in a sealed environment. The steam generated by the steam generating assembly acts on the surrounding areas of the substrate fixing members without contacting the substrate in the substrate fixing members. The steam generated by the steam generating assembly heats the substrate fixing members, causing the liquid magnetic material in the substrate fixing members to slowly flow downward, with the outflow rate being less than the evaporation and solidification rate of the liquid magnetic material.

[0021] In terms of the overall structure: The evaporation box 13 and the soaking box 14 are integrally formed. A temperature control panel 26 electrically connected to the steam generating assembly is provided on the left side of the evaporation box 13. The temperature control panel 26 detects the temperature inside the evaporation box 13 and then controls the steam generating assembly to make reasonable adjustments. A switch door 28 is rotatably connected to the evaporation box 13, and a handle 29 is provided on the switch door 28. The significance of the switch door 28 is to enable the placement of the substrate on the substrate fixing member. For example, Figure 1 and Figure 2 As shown, the soaking box 14 is used for the inlet and outlet of the liquid magnetic material. Liquid inlet pipes 15 and drain pipes are respectively and communicatively provided on both sides of the soaking box 14. The height of the liquid inlet pipe 15 is higher than that of the drain pipe.

[0022] During use: The liquid magnetic material enters through the liquid inlet pipe 15 and accumulates in the soaking box 14. When the liquid magnetic material is no longer used, it is discharged from the drain. In order to accelerate the discharge of the liquid magnetic material from the drain, the designed height of the liquid inlet pipe 15 is designed to be higher than that of the drain pipe.

[0023] In this case, the lifting plate 18 can move up and down. The initial position of the lifting plate 18 is in the soaking box 14. At this time, the soaking box 14 is not used for the inlet and outlet of the liquid magnetic material. The lifting drive assembly is preferably used, and the lifting plate 18 is driven to move upward by the lifting drive assembly; Specifically: As Figure 1 and Figure 2 shown, the lifting drive assembly includes a top plate 23 installed on the top of the evaporation box 13, a plurality of connecting rods 24 provided below the top plate 23, and a cylinder 25 installed on the top of the evaporation box 13 below the top plate 23. One end of each connecting rod 24 is fixedly connected to the top plate 23, and the other end of the connecting rod 24 passes through the soaking box and is connected to the lifting plate 18.

[0024] When the cylinder 25 is started, the top plate 23 is pushed upward, driving the connecting rods 24 to move upward. After the connecting rods 24 move upward, since the connecting rods 24 are connected to the lifting plate 18, the lifting plate 18 is caused to rise. Regarding the end position of the lifting of the lifting plate 18: As Figure 1 and Figure 2 and Figure 3 shown, a through groove is formed in the baffle 17. A clamping plate 19 is installed on the lifting plate 18. The size of the clamping plate 19 is smaller than that of the lifting plate 18. The size of the clamping plate 19 is equal to the inner diameter of the through groove. The substrate fixing members are all installed on the clamping plate 19. When the lifting plate 18 moves upward, the clamping plate 19 passes through the through groove and is clamped by the lifting plate 18. A sealed environment is formed between the lifting plate 18 and the evaporation box 13. At this time, the substrate fixing member is located at the inner bottom of the evaporation box 13; Regarding the base fixing member; the base fixing member is mainly used to store the base and cover the magnetic film on the base. Regarding the base: the base is a core component of the filter element 1. For example, Figure 6 As shown, the base is covered with a magnetic film 2 to form the filter element 1. The filter element 1 is wound with different windings. For example, Figure 6 As shown, it includes a first winding 3 and a second winding 4, becoming the core of the transformer; For example, Figure 4 and Figure 9 As shown: The base fixing member includes a base 5 and a groove 33 installed on the base 5 for storing the base. A functional block 10 is provided inside the groove 33. The functional block 10 is made of the same material as the groove 33 and is integrally formed. The groove 33 includes a clamping section 6 and a liquid leakage section 7. The clamping section 6 and the liquid leakage section 7 are integrally formed. A first inclined surface 8 is provided on the outer periphery of the functional block 10. A second inclined surface 9 is provided on one side of the clamping section 6 close to the first inclined surface 8. The first inclined surface 8 and the second inclined surface 9 are inclined in opposite directions. The bottom height of the liquid leakage section 7 is lower than the bottom height of the clamping section 6. The bottom of the liquid leakage section 7 is a liquid leakage surface 12, that is, the height of the liquid leakage surface 12 is lower than the bottom height of the clamping section 6. The liquid leakage surface 12 is essentially an inclined surface. A number of liquid leakage holes 11 are opened on the liquid leakage surface 12. The liquid leakage holes 11 are arranged at the lowest point of the above-mentioned inclined surface. Liquid leakage is realized through the liquid leakage holes 11. When the base is placed, the first inclined surface 8 cooperates with the second inclined surface 9 to clamp both sides of the base. The liquid leakage section 7 does not contact the base. The height of the groove 33 is higher than the installation height of the base; Regarding the storage of the base by the groove 33, as Figure 5 shown, the first inclined surface 8 and the second inclined surface 9 are inclined in opposite directions to form a gradually changing card slot to clamp and fix the base. That is, the first inclined surface 8 and the second inclined surface 9 are two inclined surfaces inclined in opposite directions. After being arranged in the opposite direction, a gradually changing card slot is formed. Since the gradually changing card slot has different diameters, therefore, this groove 33 can be used for bases of different sizes. Since the liquid leakage section 7 does not contact the base, the groove 33 slowly discharges the liquid magnetic material through the liquid leakage holes 11 on the liquid leakage section 7; Regarding the slow discharge of the liquid magnetic material through the liquid leakage hole 11: Since the tank 33 is in the soaking tank 14, when the liquid inlet pipe 15 and the drain pipe are opened, the liquid level rises, and the liquid magnetic material will fully cover and soak the tank 33. Then, the tank 33 moves upward and enters the evaporation tank 13. For traditional liquid magnetic materials, the film thickness difference is caused by gravity because the liquid magnetic material has a certain gravity, and due to the traditional hot air guiding effect, there is a possibility that the liquid film flows downward or is blown away, that is, there is a situation where the liquid magnetic material is not solidified. Because of gravity, it falls on the lower side of the substrate, resulting in a greater film thickness on the lower side of the substrate than on the upper side. The device adopted here is that a large amount of liquid magnetic material coexists with the substrate. Although the liquid magnetic material has a certain gravity, the amount of the liquid magnetic material is relatively large. During the evaporation and solidification time, it can ensure that the amount of the liquid magnetic material in contact with the substrate is sufficient, thereby making the film thickness of the substrate uniform. As for the slow outflow of the liquid magnetic material, it is because after the substrate is completely covered with the liquid magnetic material to form the magnetic film 2, the excess liquid magnetic material is no longer useful and naturally needs to flow out of the substrate fixture. As for the slowness, it is because the outflow time of the liquid magnetic material cannot be faster than the evaporation and solidification time. Therefore, the substrate fixture is set as a special device through which the liquid magnetic material can slowly flow out; Regarding evaporation: First, as Figure 3 shown, the steam generating assembly includes an external steam generator for generating hot steam, several conduits 27 connected to the output end of the steam generator, a steam output loop 20 installed in the evaporation tank 13 and connected to the conduits 27, and a frame-shaped output steam channel 22 connected to the steam output loop 20. The frame-shaped output steam channel 22 is formed with several output areas corresponding one by one to the number and positions of the tanks 33. A number of hot air action tubes 30 are evenly arranged in the output areas. The installation position of the steam output loop 20 is in the same plane as the position where the lifting plate 18 and the evaporation tank 13 form a sealed environment.

[0025] When the tank 33 enters the evaporation tank 13 and is affected by the output area, the hot steam at this time not only does not directly act on the substrate, but also is used to increase the overall temperature of the evaporation tank 13, thereby realizing evaporation. An exhaust hole is provided at the top of the steam tank to ensure that the air pressure in the steam tank is within a safe range; Features of the thermal evaporation in this application: The overall temperature of the evaporation box 13 is increased to raise the internal temperature of the evaporation box 13. The metal thermal conductive elasticity generated by the hot air action pipe 30 provided heats the tank body, and the temperature rise of the functional block 10 comes from the heat conduction of the tank body 33 and the heat storage of the entire evaporation box 13. There will be a temperature difference between the functional block 10 and the outer wall of the tank body 33. Since the outer wall of the tank body 33 is closest to the air outlet pipe 32, the tank body 33 will be affected by the air outlet pipe 32. However, for the liquid magnetic film, the curing temperature is fixed. Therefore, as long as the temperature of the functional block 10 rises to cure the liquid magnetic film, because the temperature rise of the functional block 10 can cure the liquid magnetic film; Regarding the hot air action pipe 30: As Figure 7 And Figure 8 shown, the hot air action pipe 30 is arranged around the tank body 33. The end of the hot air action pipe 30 is sealed and the hot air action pipe 30 is made of metal. When the tank body 33 rises, the sealed end 31 of the hot air action pipe 30 contacts the tank body 33. An air outlet pipe 32 is arranged on the hot air action pipe 30 near the sealed end 31 of the hot air action pipe 30, and the air outlet direction of the air outlet pipe 32 does not act on the tank body 33; Specifically: Since the hot air action pipe 30 is made of metal and the sealed end 31 contacts the tank body 33, the tank body 33 is heated, and the evaporation rate of the liquid magnetic material located in the substrate is increased by heat. And as Figure 8 shown, the air outlet pipes 32 are arranged up and down and do not directly contact the substrate, so that the substrate is not affected by the hot air force. And because the hot air action pipe 30 is arranged around the tank body 33, after the air outlet pipes 32 discharge air, local evaporation is formed around the tank body 33, thereby improving the evaporation effect.

[0026] The liquid magnetic material in this application is a nano-particle dispersion film, specifically composed of magnetic nanoparticles such as magnetite dispersed in a liquid medium such as acrylic resin. The principle of drying and curing is a synergistic process of solvent removal from the liquid magnetic material, particle aggregation of the liquid magnetic material, and interfacial anchoring with the substrate; Therefore, it is necessary to strictly determine the drying temperature of the liquid magnetic material according to the actual substrate and the liquid magnetic material. Because if the evaporation and curing time is much faster than the outflow time of the liquid magnetic material, after the liquid magnetic material forms the magnetic film 2, the liquid magnetic material in the tank 33 has not flowed out yet. However, at this time, the liquid magnetic material will not form a thicker magnetic film 2 on the original magnetic film 2, because after the initial magnetic film 2 is formed, the condition of interfacial anchoring with the substrate has disappeared. At this time, if you want to form a thicker magnetic film 2 again, it is necessary to sinter at a high temperature to destroy the initial magnetic film 2 so that the condition of interfacial anchoring of the substrate reappears. Therefore, the drying and curing of the liquid magnetic material requires a strict temperature, which is the critical temperature for the liquid magnetic material to form the magnetic film 2.

[0027] This device solves the problem of obvious film thickness differences in the baking devices covered with the magnetic film 2 of the cores used in traditional transformers.
