Description

Technical Field

[0001] This invention relates to the field of magnetic core manufacturing technology, and in particular to a magnetic core insulation layer spraying device. Background Technology

[0002] Existing toroidal magnetic cores are widely used in electronic communication equipment, electronic power control systems, and industrial control equipment. These toroidal magnetic cores are small in size, with a sheet width of 6–25 mm, an inner diameter of φ8–30 mm, and an outer diameter of φ10–35 mm. Current toroidal magnetic core insulation coating typically involves two separate ovens for preheating and drying / curing. The toroidal magnetic core is hung in the preheating oven for preheating at 135℃–150℃ for 25–30 minutes. The purpose of preheating is to remove residual moisture from the toroidal magnetic core, ensuring it dries quickly and is less prone to rusting, allowing for faster powder application and a thicker coating during spraying. The manually coated toroidal magnetic core is then hung in the drying oven for drying / curing at 200℃–230℃ for 10–12 minutes.

[0003] However, existing toroidal magnetic core coating processes have many problems. For example, Chinese patent CN115502017A discloses a toroidal magnetic core insulation layer coating production line and method. This production line includes a tunnel furnace, a rotary table, a powder spraying chamber, and a powder recovery chamber, and uses automated equipment to realize the preheating, spraying, and drying / curing processes of the toroidal magnetic core. Although this technology improves production efficiency to some extent, it still has the following shortcomings: during powder spraying in the powder spraying chamber, the tray carrying the magnetic core is also sprayed, causing powder to adhere to the tray and resulting in powder waste. This waste not only increases production costs but also reduces spraying efficiency, because the powder on the tray needs to be cleaned regularly, otherwise it will affect the coating quality of subsequent magnetic cores. Summary of the Invention

[0004] The purpose of this invention is to provide a magnetic core insulation layer spraying device, which significantly reduces powder waste and lowers production costs by separately transporting the magnetic core to the powder spraying booth for spraying.

[0005] In a first aspect, the present invention provides a magnetic core insulation layer spraying apparatus, comprising:

[0006] Preheating box;

[0007] curing box;

[0008] A conveyor belt is installed sequentially through the preheating box and the curing box, and a handling space is reserved between the preheating box and the curing box;

[0009] A support platform is provided on the conveyor belt. The support platform is provided with a plurality of spaced first transport slots. The conveyor belt can drive the support platform to move between the preheating box and the curing box.

[0010] A powder spraying room is provided with a powder spraying cavity, and a powder spraying table is provided inside the powder spraying cavity. The powder spraying table is provided with multiple spaced-apart second transport troughs.

[0011] A transport mechanism is movably disposed within the transport space. The transport mechanism is provided with a plurality of spaced-apart support plates. The transport mechanism can drive the plurality of support plates to insert into the first transport slot or the second transport slot to transport the magnetic core between the powder spraying table and the support table.

[0012] The magnetic core insulation layer spraying device provided by this invention achieves direct transport of the magnetic core by setting up multiple support plates in conjunction with the first transport groove of the support platform and the second transport groove of the powder spraying platform, thus avoiding the use of trays. In the traditional spraying process, the tray is sprayed, resulting in a large amount of powder adhering to the tray and wasting powder. This device, by transporting the magnetic core individually, ensures that the powder adheres only to the surface of the magnetic core, significantly reducing powder waste and lowering production costs. In addition, the elimination of the use of trays reduces the purchase, maintenance, and cleaning costs of trays, further reducing production costs and improving the economics of production.

[0013] Furthermore, the preheating box includes a first preheating box and a second preheating box, and the curing box includes a first curing box and a second curing box. The conveyor belt is arranged to pass through the first preheating box, the first curing box, the second preheating box, and the second curing box in sequence. There are two transport mechanisms, one of which is located between the first preheating box and the first curing box, and the other of which is located between the second preheating box and the second curing box. There are two powder spraying booths, and the two transport mechanisms can transport the magnetic core towards the two powder spraying booths respectively. The two powder spraying booths are used to spray the opposite sides of the magnetic core respectively.

[0014] By adopting the above technical solution, and by setting up the preheating box and curing box in sections, and equipping them with two conveying mechanisms and two powder spraying booths, separate spraying and curing of both sides of the magnetic core can be achieved. This design eliminates the need for frequent equipment adjustments during the preheating, spraying, and curing processes of the magnetic core, reducing operating steps and improving production efficiency.

[0015] Furthermore, there are multiple support platforms, which are spaced apart on the conveyor belt.

[0016] By adopting the above technical solution and increasing the number of support platforms, multiple magnetic cores can be preheated, powder coated, and cured simultaneously. This design allows two preheating chambers, two curing chambers, and two powder coating booths to operate concurrently, significantly improving production efficiency. By segmenting the preheating and curing chambers and increasing the number of support platforms, each part of the equipment can be utilized efficiently, reducing idle time and improving overall equipment utilization.

[0017] Furthermore, the conveyor belt includes a first arc-shaped conveyor belt, a first straight conveyor belt, a second arc-shaped conveyor belt, and a second straight conveyor belt connected end to end. The first preheating box and the first curing box are disposed on the first straight conveyor belt, and the second preheating box and the second curing box are disposed on the second straight conveyor belt. The first arc-shaped conveyor belt is used for placing the magnetic core on the support platform, and the second arc-shaped conveyor belt is used for flipping the magnetic core on the support platform.

[0018] By adopting the above technical solution, the segmented design of the conveyor belt makes reasonable use of space, so that the footprint of the entire device does not increase significantly, thus improving the space utilization rate of the equipment.

[0019] Furthermore, the powder coating booth includes a first color powder coating booth and a second color powder coating booth, which can spray powder of different colors. The conveying mechanism can transport the magnetic core on the support platform to the first color powder coating booth or the second color powder coating booth for spraying.

[0020] By employing the above technical solution and setting up two powder coating booths of different colors, the magnetic core can be coated with multiple colors to meet the color requirements of different customers. This design not only enhances the product's market competitiveness but also adapts to the needs of different application scenarios. Furthermore, the two powder coating booths can operate simultaneously, each applying a different color, improving the overall utilization rate of the equipment and reducing downtime. This parallel operation mode significantly improves production efficiency. Frequent color changes in a single powder coating booth lead to increased equipment setup time; however, by setting up two powder coating booths, this frequent adjustment can be avoided, further improving production efficiency.

[0021] Furthermore, the transport mechanism includes a first transport mechanism and a second transport mechanism. The support plate on the first transport mechanism is located on the side of the first transport mechanism away from the second transport mechanism, and the first transport mechanism is used to transport the magnetic core to the first color powder spraying room. The support plate on the second transport mechanism is located on the side of the second transport mechanism away from the first transport mechanism, and the second transport mechanism is used to transport the magnetic core to the second color powder spraying room.

[0022] Using the above technical solution, the first and second transport mechanisms are responsible for transporting the magnetic cores to the first and second color powder spraying chambers, respectively. This design completely separates the two transport mechanisms physically, preventing powders of different colors from coming into contact with each other during transport, thus effectively preventing powder color mixing. Independent transport paths ensure the purity of the powder color in each powder spraying chamber, avoiding a decrease in coating quality due to powder mixing, and further improving the uniformity and consistency of the coating.

[0023] Furthermore, the conveying mechanism includes a gantry frame, a translation component, a lifting component, and an L-shaped plate. The conveyor belt passes through the gantry frame, the translation mechanism is mounted on the gantry frame, the lifting component is translatably mounted on the translation component, one end of the L-shaped plate is vertically mounted on the lifting component, and multiple support plates are horizontally spaced on the other end of the L-shaped plate.

[0024] By adopting the above technical solution, through the coordinated action of the translation component and the lifting component, the conveying mechanism can accurately insert the support plate into the first or second conveying slot, ensuring that the transfer of the magnetic core between each process is more accurate and reducing uneven coating or equipment failure caused by positional deviation.

[0025] Furthermore, the conveyor belt includes drive wheels, a drive belt, and an annular slide rail. There are multiple drive wheels, and the drive belt is sleeved on the multiple drive wheels. The support platform is movably disposed on the annular slide rail, and the support platform is fixedly connected to the drive belt. The multiple drive wheels can drive the support platform to move on the annular slide rail through the drive belt.

[0026] By adopting the above technical solution, the combination of drive wheel, drive belt and circular slide rail enables the continuous transport of magnetic cores, reducing the waiting time of magnetic cores between various processes and significantly improving production efficiency.

[0027] Furthermore, it also includes a cooling fan, which is located at the outlet of the curing chamber and is used to cool the cured magnetic core.

[0028] Using the above technical solution, the temperature of the cured magnetic core is relatively high. If it is not cooled down in time, it may cause damage or deformation to the coating on the core surface. A cooling fan can quickly reduce the temperature of the magnetic core, preventing thermal damage caused by high temperatures and ensuring product quality. Through the uniform cooling of the cooling fan, the cooling process of the magnetic core is more even, avoiding localized overheating or overcooling, and further improving the quality and consistency of the coating.

[0029] Furthermore, it also includes a cyclone separation mechanism, which is connected to the powder spraying cavity via a recovery pipe. The cyclone separation mechanism can extract powder from the powder spraying cavity through the recovery pipe.

[0030] By adopting the above technical solution, the powder that does not adhere to the surface of the magnetic core during the powder spraying process can be recycled and reused through the cyclone separation mechanism, which significantly reduces powder waste and lowers production costs.

[0031] As can be seen from the above, the magnetic core insulation layer spraying device provided by the present invention achieves direct transport of the magnetic core by setting multiple support plates in conjunction with the first transport groove of the support platform and the second transport groove of the powder spraying platform, thus avoiding the use of trays. In the traditional spraying process, the tray is sprayed, resulting in a large amount of powder adhering to the tray, causing powder waste. This device, by transporting the magnetic core separately, ensures that the powder adheres only to the surface of the magnetic core, significantly reducing powder waste and lowering production costs. In addition, the use of trays is avoided, reducing the purchase, maintenance, and cleaning costs of trays, further reducing production costs and improving the economics of production.

[0039] Embodiments of the present invention are described in detail below, examples of which are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and should not be construed as limiting the present invention.

[0040] The following disclosure provides many different embodiments or examples for implementing different structures of the invention. To simplify the disclosure, specific examples of components and arrangements are described below. Of course, these are merely examples and are not intended to limit the invention. Furthermore, reference numerals and / or letters may be repeated in different examples; such repetition is for simplification and clarity and does not in itself indicate a relationship between the various embodiments and / or arrangements discussed.

[0041] The magnetic core insulation layer spraying device disclosed in this invention is mainly used in the insulation layer spraying of toroidal magnetic cores. By transporting the magnetic core separately to the powder spraying room for spraying, the waste of powder spraying is significantly reduced and the production cost is lowered.

[0042] Reference Appendix Figure 1 Appendix Figure 2In one embodiment, the magnetic core insulation layer spraying device includes a preheating box 100, a curing box 200, a conveyor belt 300, a support platform 500, a powder spraying chamber 600, and a handling mechanism 700. A conveyor belt 300 is sequentially installed through the preheating chamber 100 and the curing chamber 200, with a transport space 400 reserved between them. A support platform 500 is mounted on the conveyor belt 300 and has multiple spaced first transport slots 510. The conveyor belt 300 can drive the support platform 500 to move between the preheating chamber 100 and the curing chamber 200. A powder spraying chamber 600 has a powder spraying cavity 610, and a powder spraying table 620 is installed inside the cavity. The powder spraying table 620 has multiple spaced second transport slots 630. A transport mechanism 700 is movably installed within the transport space 400 and has multiple spaced support plates 710. The transport mechanism 700 can drive the multiple support plates 710 to insert into the first transport slots 510 or the second transport slots 630 to transport the magnetic core between the powder spraying table 620 and the support platform 500.

[0043] Specifically, the conveyor belt 300 passes sequentially through the preheating chamber 100 and the curing chamber 200, with a support platform 500 positioned on the conveyor belt 300. The magnetic core is placed on the support platform 500 and moves with the conveyor belt 300, passing sequentially through the preheating chamber 100 and the curing chamber 200 to complete the preheating and curing processes. The transport mechanism 700 drives multiple support plates 710 to insert from the side into the first transport groove 510 on the support platform 500, transferring the magnetic core from the support platform 500 to the support plates 710. The transport mechanism 700 then moves the support plates 710 to the second transport groove 630 on the powder spraying station 620, completing the transfer of the magnetic core from the support plates 710 to the powder spraying station 620. During powder spraying, the support plates 710 are removed from the powder spraying cavity 610, avoiding the use of a tray and reducing powder waste. After powder coating is completed, the transport mechanism 700 moves the magnetic core from the powder coating station 620 back to the support platform 500, and the conveyor belt 300 carries the powder-coated magnetic core into the curing box 200 for curing. After curing, the magnetic core completes the entire insulation layer coating process.

[0044] As can be seen from the above, the magnetic core insulation layer spraying device provided by the present invention, by setting multiple support plates 710 in conjunction with the first transport groove 510 of the support platform 500 and the second transport groove 630 of the powder spraying table 620, achieves direct transport of the magnetic core, avoiding the use of a tray. In the traditional spraying process, the tray is sprayed, resulting in a large amount of powder adhering to the tray, causing powder waste. This device, by transporting the magnetic core separately, ensures that the powder adheres only to the surface of the magnetic core, significantly reducing powder waste and lowering production costs. In addition, the use of trays is avoided, reducing the purchase, maintenance, and cleaning costs of trays, further reducing production costs and improving the economic efficiency of production.

[0045] Reference Appendix Figure 1In one embodiment, the preheating chamber 100 includes a first preheating chamber 110 and a second preheating chamber 120, the curing chamber 200 includes a first curing chamber 210 and a second curing chamber 220, and the conveyor belt 300 is arranged to pass through the first preheating chamber 110, the first curing chamber 210, the second preheating chamber 120 and the second curing chamber 220 in sequence. There are two conveying mechanisms 700, one of which is located between the first preheating chamber 110 and the first curing chamber 210, and the other of which is located between the second preheating chamber 120 and the second curing chamber 220. There are two powder spraying chambers 600, and the two conveying mechanisms 700 can respectively move the magnetic core toward the two powder spraying chambers 600. The two powder spraying chambers 600 are respectively used to spray the opposite sides of the magnetic core.

[0046] Specifically, the magnetic core is first preheated in the first preheating chamber 110, and then transferred to the powder coating chamber 600 by the transport mechanism 700 for spraying. After spraying, the magnetic core is transferred to the first curing chamber 210 by the transport mechanism 700 for curing. After curing, the magnetic core on the support platform 500 is flipped over, and the flipped magnetic core is moved to the second preheating chamber 120 by the conveyor belt 300 for preheating again. After preheating, the flipped magnetic core is transferred to the powder coating chamber 600 by the transport mechanism 700 for spraying the other side. Finally, the magnetic core is transferred to the second curing chamber 220 by the transport mechanism 700 for curing, completing the entire spraying process.

[0047] By adopting the above technical solution, and by segmenting the preheating chamber 100 and the curing chamber 200, and equipping them with two conveying mechanisms 700 and two powder spraying booths 600, separate spraying and curing of both sides of the magnetic core can be achieved. This design eliminates the need for frequent equipment adjustments during the preheating, spraying, and curing processes of the magnetic core, reducing operational steps and improving production efficiency.

[0048] In one embodiment, there are multiple support platforms 500, which are spaced apart on the conveyor belt 300.

[0049] By adopting the above technical solution and increasing the number of support platforms 500, multiple magnetic cores can be preheated, powder coated, and cured simultaneously. This design allows two preheating chambers 100, two curing chambers 200, and two powder coating chambers 600 to operate concurrently, significantly improving production efficiency. By segmenting the preheating chambers 100 and curing chambers 200 and increasing the number of support platforms 500, each part of the equipment can be utilized efficiently, reducing idle time and improving overall equipment utilization.

[0050] In one embodiment, the conveyor belt 300 includes a first arc-shaped conveyor belt 310, a first straight conveyor belt 320, a second arc-shaped conveyor belt 330, and a second straight conveyor belt 340 connected end to end. A first preheating box 110 and a first curing box 210 are disposed on the first straight conveyor belt 320, and a second preheating box 120 and a second curing box 220 are disposed on the second straight conveyor belt 340. The first arc-shaped conveyor belt 310 is used for placing magnetic cores on the support platform 500, and the second arc-shaped conveyor belt 330 is used for flipping the magnetic cores on the support platform 500.

[0051] Specifically, the magnetic core is first placed on the support platform 500 on the first arc-shaped conveyor belt 310.

[0052] The support platform 500 moves with the first arc-shaped conveyor belt 310 and enters the first preheating box 110 on the first straight conveyor belt 320 for preheating.

[0053] After preheating, the transport mechanism 700 transfers the magnetic core from the support platform 500 to the powder spraying chamber 600 for spraying.

[0054] After the coating is completed, the transport mechanism 700 transfers the magnetic core to the first curing box 210 for curing.

[0055] After curing, the magnetic core is moved by conveyor belt 300 to the second arc-shaped conveyor belt 330 for flipping.

[0056] After being flipped over, the magnetic core enters the second preheating box 120 on the second linear conveyor belt 340 for reheating.

[0057] After the second preheating is completed, the transport mechanism 700 transfers the magnetic core to the powder coating chamber 600 for coating the other side.

[0058] Finally, the magnetic core is transferred to the second curing box 220 by the conveying mechanism 700 for curing, completing the entire spraying process.

[0059] By adopting the above technical solution, the segmented design of the conveyor belt 300 makes reasonable use of space, so that the footprint of the entire device does not increase significantly, thus improving the space utilization rate of the equipment.

[0060] In one embodiment, a cooling fan 800 is also included. The cooling fan 800 is located at the outlet of the curing chamber 200 and is used to cool the cured magnetic core.

[0061] Specifically, after the magnetic core is cured in the curing chamber 200, it is moved to the exit of the curing chamber 200 by the conveyor belt 300. A cooling fan 800 rapidly cools the freshly cured magnetic core to prevent damage or deformation due to high temperatures. The cooled magnetic core can then be safely processed or packaged, improving production continuity and safety.

[0062] Using the above technical solution, the temperature of the cured magnetic core is relatively high. If it is not cooled down in time, it may cause damage or deformation to the coating on the surface of the magnetic core. The cooling fan 800 can quickly reduce the temperature of the magnetic core, prevent thermal damage caused by high temperature, and ensure product quality. Through the uniform cooling of the cooling fan 800, the cooling process of the magnetic core is more uniform, avoiding local overheating or overcooling, and further improving the quality and consistency of the coating.

[0063] In one embodiment, a cyclone separator 900 is also included. The cyclone separator 900 and the powder spraying cavity 610 are connected by a recovery pipe 910. The cyclone separator 900 can extract powder from the powder spraying cavity 610 through the recovery pipe 910.

[0064] Specifically, during the powder coating process, powder that does not adhere to the magnetic core surface will scatter within the powder coating chamber 600. The cyclone separator 900 extracts this scattered powder through the recovery pipe 910. The extracted powder, after being filtered and separated by the cyclone separator 900, can be reused for coating, reducing powder waste.

[0065] By adopting the above technical solution, the cyclone separation mechanism 900 can recycle and reuse the powder that does not adhere to the surface of the magnetic core during the powder spraying process, which significantly reduces powder waste and lowers production costs.

[0066] Reference Appendix Figure 2 In one embodiment, the conveying mechanism 700 includes a gantry frame 740, a translation component 750, a lifting component 760, and an L-shaped plate 770. The conveyor belt 300 passes through the gantry frame 740. The translation component 750 is mounted on the gantry frame 740. The lifting component 760 is translatably mounted on the translation component 750. One end of the L-shaped plate 770 is vertically mounted on the lifting component 760. A plurality of support plates 710 are horizontally spaced on the other end of the L-shaped plate 770.

[0067] By adopting the above technical solution, through the coordinated action of the translation component 750 and the lifting component 760, the conveying mechanism 700 can accurately insert the support plate 710 into the first conveying slot 510 or the second conveying slot 630, ensuring that the transfer of the magnetic core between each process is more accurate and reducing uneven spraying or equipment failure caused by position deviation.

[0068] Reference Appendix Figure 3 In one embodiment, the powder spraying chamber 600 includes a first color powder spraying chamber 640 and a second color powder spraying chamber 650. The first color powder spraying chamber 640 and the second color powder spraying chamber 650 are capable of spraying powder of different colors. The conveying mechanism 700 is capable of conveying the magnetic core on the support platform 500 to the first color powder spraying chamber 640 or the second color powder spraying chamber 650 for spraying.

[0069] Specifically, the powder coating booth 600 can also include a third-color powder coating booth and a fourth-color powder coating booth, thereby meeting the requirements for coating various different colored insulation layers.

[0070] It is worth noting that in the above embodiment, two powder spraying chambers 600 are set to spray the opposite sides of the magnetic core respectively. The number of powder spraying chambers 600 is two. In this embodiment, it should be understood that each of the two powder spraying chambers 600 includes a first color powder spraying chamber 640 and a second color powder spraying chamber 650. That is, there are a total of two first color powder spraying chambers 640 and two second color powder spraying chambers 650. The two first color powder spraying chambers 640 and the two second color powder spraying chambers 650 respectively spray the opposite sides of the magnetic core with two colors.

[0071] By employing the above technical solution and setting up two powder coating chambers 600 of different colors, multiple colors of powder coating can be applied to the magnetic core, meeting the color requirements of different customers. This design not only enhances the product's market competitiveness but also adapts to the needs of different application scenarios. Furthermore, the two powder coating chambers 600 can operate simultaneously, each applying a different color, improving the overall utilization rate of the equipment and reducing idle time. This parallel operation mode significantly improves production efficiency. Frequent color changes in a single powder coating chamber 600 would increase equipment setup time, while setting up two powder coating chambers 600 avoids this frequent adjustment, further improving production efficiency.

[0072] Reference Appendix Figure 4 In one embodiment, the transport mechanism 700 includes a first transport mechanism 720 and a second transport mechanism 730. A support plate 710 on the first transport mechanism 720 is disposed on the side of the first transport mechanism 720 away from the second transport mechanism 730. The first transport mechanism 720 is used to transport the magnetic core to the first color powder spraying chamber 640. The support plate 710 on the second transport mechanism 730 is disposed on the side of the second transport mechanism 730 away from the first transport mechanism 720. The second transport mechanism 730 is used to transport the magnetic core to the second color powder spraying chamber 650.

[0073] It is worth noting that in the above embodiment, two transport mechanisms 700 are provided to transport the magnetic core before and after flipping. The number of transport mechanisms 700 is two. In this embodiment, it should be understood that each of the two transport mechanisms 700 includes a first transport mechanism 720 and a second transport mechanism 730, that is, there are a total of two first transport mechanisms 720 and two second transport mechanisms 730.

[0074] Using the above technical solution, the first transport mechanism 720 and the second transport mechanism 730 are respectively responsible for transporting the magnetic core to the first color powder spraying chamber 640 and the second color powder spraying chamber 650. This design completely separates the two transport mechanisms physically, preventing powders of different colors from coming into contact with each other during transport, thus effectively preventing the problem of powder color mixing. Independent transport paths ensure the purity of the powder color in each powder spraying chamber 600, avoiding a decrease in coating quality due to powder mixing, and further improving the uniformity and consistency of the coating.

[0075] Reference Appendix Figure 5 In one embodiment, the conveyor belt 300 includes drive wheels 350, drive belt 360, and annular slide rail 370. There are multiple drive wheels 350, and the drive belt 360 is sleeved on the multiple drive wheels 350. The support platform 500 is movably disposed on the annular slide rail 370, and the support platform 500 is fixedly connected to the drive belt 360. The multiple drive wheels 350 can drive the support platform 500 to move on the annular slide rail 370 through the drive belt 360.

[0076] Specifically, the drive wheel 350 drives the support platform 500 to move on the annular slide rail 370 via the drive belt 360, thereby realizing the continuous conveying of the magnetic core between the preheating box 100, the powder spraying chamber 600 and the curing box 200.

[0077] By adopting the above technical solution, through the combination of drive wheel 350, drive belt 360 and annular slide rail 370, the conveyor belt 300 can realize the continuous transport of magnetic cores, reduce the waiting time of magnetic cores between various processes, and significantly improve production efficiency.
