Description

Technical Field

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

[0002] Magnetic cores are magnetic materials widely used in coils and transformers of various electronic devices. To improve their voltage withstand capability and performance stability, they are typically coated with powder to form an insulating layer. However, existing toroidal magnetic core coating equipment suffers from numerous problems in practical applications.

[0003] For example, Chinese patent application CN115502017A discloses a production line and method for spraying insulation layers onto toroidal magnetic cores. 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 cores. Although this production line improves spraying efficiency to some extent, during spraying in the powder spraying chamber, the trays supporting the magnetic cores are also sprayed, causing powder to adhere to the trays. This not only wastes powder but also increases tray wear and reduces the equipment's lifespan.

[0004] To solve the above problems, please refer to the appendix. Figure 1 Appendix Figure 2 The applicant has proposed an improved magnetic core insulation coating device. This device uses multiple support plates 11 mounted on the magnetic core transport mechanism 10, which are directly inserted into the transport groove 210 of the support platform 20 and the powder spraying platform 200, thus achieving direct transport of the magnetic core and avoiding the use of pallets. However, while this design reduces the use of pallets, the presence of the transport groove 210 allows powder to easily enter and deposit within it during coating, affecting the normal entry and exit of the magnetic core transport mechanism 10 from the transport groove 210, thereby reducing the operating efficiency and reliability of the equipment. Summary of the Invention

[0005] The purpose of this invention is to provide a magnetic core spraying booth and a magnetic core insulation layer spraying production line, which effectively solves the powder deposition problem by optimizing the design of the transport trough and adding structures such as powder spraying baffles.

[0006] In a first aspect, the present invention provides a magnetic core spraying booth, comprising:

[0007] The spraying machine housing is provided with a working cavity and a feed inlet. The feed inlet is connected to the working cavity so that the magnetic core transport mechanism can enter or leave the working cavity.

[0008] A powder spraying table is located inside the working cavity. The powder spraying table is used to carry the magnetic core and has multiple spaced transport slots.

[0009] A powder spraying gun is movably mounted above the powder spraying table, and the powder spraying gun is used to spray powder onto the magnetic core on the powder spraying table;

[0010] A lifting mechanism is located below the powder spraying table. The lifting mechanism has multiple powder spraying baffles spaced apart. The multiple powder spraying baffles can be lifted and lowered into multiple transport slots. The lifting mechanism can drive the powder spraying baffles to rise until they abut against the magnetic core on the powder spraying table to prevent the powder sprayed by the powder spraying gun from entering the transport slot. The powder spraying baffles can also be lowered so that the magnetic core transporting mechanism can be inserted into the transport slot to place or pick up the magnetic core on the powder spraying table.

[0011] The magnetic core spraying booth provided by this invention features a lifting mechanism and a powder spraying baffle below the powder spraying station. The baffle rises during the spraying process to contact the magnetic core, effectively preventing powder sprayed from the spray gun from entering the transport tank. This solves the problem of powder easily entering and accumulating in the transport tank in existing technologies, avoiding interference from powder accumulation in the transport tank on the magnetic core transport mechanism, and improving the operating efficiency and reliability of the equipment. Simultaneously, when the baffle descends, it provides sufficient space for the magnetic core transport mechanism, allowing it to smoothly insert into the transport tank and place or pick up the magnetic core. This design protects the transport mechanism from powder contamination and extends its service life. Furthermore, the baffle not only effectively prevents powder from entering the transport tank during spraying but also supports the magnetic core, ensuring its stability during spraying and preventing uneven spraying caused by core shaking or displacement. This helps improve the uniformity of the coating on the magnetic core surface, thereby enhancing the magnetic core's voltage resistance and performance stability.

[0012] Furthermore, the lifting mechanism includes a connecting rod, a driving component, and a driven component. Each of the multiple powder spraying partitions has a connecting hole on the side away from the powder spraying gun. The connecting rod can pass through the connecting holes of the multiple powder spraying partitions in sequence. The driven component is connected to the output end of the driving component and the connecting rod respectively. The driving component can drive the connecting rod to rise or fall through the driven component.

[0013] Using the above technical solution, the connecting rod passes sequentially through the connecting holes of multiple powder coating baffles, ensuring that all powder coating baffles can rise and fall synchronously. This design guarantees the consistency of the powder coating baffles during the rising or falling process, avoiding problems such as uneven coating or blockage of the transport tank caused by uncoordinated movement of individual baffles.

[0014] Furthermore, the driven assembly includes a driven rod and a fixing plate. The driven rod is located below the plurality of powder spraying partitions. There are two fixing plates, which are respectively located on opposite sides of the plurality of powder spraying partitions. Each fixing plate has a first fixing hole and a second fixing hole. The first fixing hole is used for the opposite ends of the connecting rod to pass through and be fixed, and the second fixing hole is used for the driven rod to pass through and be fixed. The driving assembly drives the connecting rod to rise or fall through the driven rod.

[0015] With the above technical solution, the driven rod is located below the powder spraying partition, while two fixing plates are respectively set on opposite sides of the powder spraying partition. The first fixing hole and the second fixing hole on the fixing plate are used to fix the connecting rod and the driven rod, thereby connecting multiple connecting rods, fixing plates and driven rods into a whole. This design further enhances the connection stability between components and ensures that the entire lifting mechanism can operate smoothly during the working process.

[0016] Furthermore, the driven component also includes a first connecting horizontal plate, and the number of driven rods is at least two. The at least two driven rods are disposed through the first connecting horizontal plate, and the output end of the drive component drives the driven rods to rise or fall through the first connecting horizontal plate.

[0017] Using the above technical solution, the number of driven rods is at least two, and at least two driven rods are arranged through the first connecting cross plate. This design, through the combination of multiple driven rods and the first connecting cross plate, significantly enhances the support strength of the driven assembly, ensuring that the connecting rod can withstand greater forces during lifting and lowering, and avoiding bending or deformation.

[0018] Furthermore, the drive assembly includes a drive cylinder and a drive rod. The drive rod is vertically mounted inside the drive cylinder. There are two first connecting cross plates, and a fixing rod is provided between the two first connecting cross plates. The end of the drive rod facing the fixing rod is provided with a connecting sleeve hole, and the fixing rod passes through the connecting sleeve hole.

[0019] The above technical solution includes a connecting sleeve hole at the end of the drive rod facing the fixed rod, two first connecting cross plates, and a fixed rod between the two first connecting cross plates, with the fixed rod passing through the connecting sleeve hole. This design, through the cooperation of the connecting sleeve hole and the fixed rod, ensures a firm and reliable connection between the drive rod and the driven component.

[0020] Furthermore, the driven assembly also includes a second connecting horizontal plate, a buffer rod, and a buffer cylinder. At least two of the driven rods are disposed through the second connecting horizontal plate. The buffer cylinder is fixedly disposed below the second connecting horizontal plate. The buffer rod is disposed inside the buffer cylinder. The second connecting horizontal plate can descend with the driven rods to abut against the buffer rod.

[0021] By employing the above technical solution, the combination of the buffer cylinder and the buffer rod effectively reduces the impact force between the driven rod and the buffer rod during rapid descent. This buffering effect not only protects the buffer rod and the driven rod but also reduces the impact on the entire device. By reducing impact and vibration, the buffering mechanism significantly improves the service life of the equipment and lowers its maintenance costs.

[0022] Furthermore, it also includes a first translation mechanism, a second translation mechanism, and a connecting plate. The first translation mechanism is disposed on the spraying machine housing, and the spraying machine housing is provided with a movable hole communicating with the working cavity. The connecting plate is movably disposed in the movable hole, and the opposite ends of the connecting plate are respectively connected to the first translation mechanism and the second translation mechanism. The movement direction of the second translation mechanism is perpendicular to the movement direction of the first translation mechanism. The powder spraying gun is disposed on the second translation mechanism. The first translation mechanism and the second translation mechanism can drive the powder spraying gun to move above the powder spraying table.

[0023] By adopting the above technical solution, and by placing the first translation mechanism outside the working cavity and connecting it to the second translation mechanism through a connecting plate and a moving hole, the volume of the working cavity is significantly reduced. A smaller working cavity volume means a smaller diffusion range for powder spraying, reducing powder waste. This not only improves spraying efficiency but also reduces production costs.

[0024] Furthermore, the working cavity includes an interconnected powder spraying cavity and a clearance cavity. The powder spraying cavity is equipped with the powder spraying platform. The powder spraying gun can move into the powder spraying cavity to spray powder onto the magnetic core on the powder spraying platform. The powder spraying gun can also move into the clearance cavity to avoid the magnetic core transport mechanism.

[0025] By adopting the above technical solution, the powder spraying gun can spray the magnetic core within the powder spraying cavity, while leaving space for the magnetic core transport mechanism within the clearance cavity. When the powder spraying gun is within the clearance cavity, it will not interfere with the normal operation of the magnetic core transport mechanism, thus improving the overall operating efficiency of the equipment.

[0026] Furthermore, the powder spraying baffle has an abutment end facing the powder spraying gun, and the extension width of the abutment end decreases from away from the powder spraying gun to close to the powder spraying gun.

[0027] By adopting the above technical solution, the contact area between the powder spraying baffle and the magnetic core is significantly reduced by designing the extension width of the contact end in a decreasing form. The smaller contact area means that the amount of powder adhering to the back of the magnetic core is greatly reduced, avoiding the problem of uneven coating caused by powder contamination, thereby improving the coating quality after the magnetic core is flipped over.

[0028] Secondly, the present invention provides a magnetic core insulation layer spraying production line, comprising:

[0029] The magnetic core spraying booth mentioned above;

[0030] Preheating box;

[0031] curing box;

[0032] A conveyor belt is sequentially installed between the preheating box and the curing box, and the conveyor belt can drive the magnetic core sequentially through the preheating box and the fixing box;

[0033] A magnetic core transport mechanism is located between the preheating chamber and the curing chamber. The magnetic core transport mechanism can transport magnetic cores that have passed through the preheating chamber on the conveyor belt to the powder spraying table for spraying. The magnetic core transport mechanism can also transport magnetic cores that have been sprayed on the powder spraying table to the conveyor belt for transport to the curing chamber.

[0034] As can be seen from the above, the magnetic core spraying booth provided by the present invention, by setting a lifting mechanism and a powder spraying baffle below the powder spraying station, allows the powder spraying baffle to rise to abut against the magnetic core during the spraying process, effectively preventing the powder sprayed by the powder spraying gun from entering the transport tank. This solves the problem of powder easily entering and depositing in the transport tank in the prior art, avoiding interference from powder accumulation in the transport tank on the magnetic core transporting mechanism, and improving the operating efficiency and reliability of the equipment. At the same time, when the powder spraying baffle descends, it provides sufficient space for the magnetic core transporting mechanism, allowing it to smoothly insert into the transport tank and place or pick up the magnetic core. This design protects the transporting mechanism from powder contamination and extends its service life. In addition, the powder spraying baffle not only effectively prevents powder from entering the transport tank during the spraying process, but also supports the magnetic core, thereby ensuring the magnetic core remains stable during the spraying process, avoiding uneven spraying caused by magnetic core shaking or displacement, helping to improve the uniformity of the coating on the magnetic core surface, thereby improving the magnetic core's voltage resistance and performance stability.

[0045] 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.

[0046] 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.

[0047] The magnetic core spraying booth disclosed in this invention is mainly used in the spraying of the insulating layer of toroidal magnetic cores. By optimizing the design of the transport trough and adding structures such as powder spraying partitions, the problem of powder deposition is effectively solved.

[0048] Reference Appendix Figure 3 Appendix Figure 4 In one embodiment, the magnetic core coating booth includes a coating machine housing 100, a powder spraying table 200, a powder spraying gun 300, and a lifting mechanism 400. The coating machine housing 100 has a working cavity 110 and a feed inlet 120, the feed inlet 120 connecting to the working cavity 110 to allow the magnetic core transport mechanism 10 to enter or exit the working cavity 110. The powder spraying table 200 is located within the working cavity 110 and is used to support the magnetic core. The powder spraying table 200 has multiple spaced transport slots 210. The powder spraying gun 300 is movably positioned above the powder spraying table 200 and is used to spray powder onto the magnetic core on the powder spraying table 200. The lifting mechanism 400... Located below the powder spraying table 200, the lifting mechanism 400 is equipped with multiple spaced powder spraying baffles 410. The multiple powder spraying baffles 410 can be lifted and lowered within multiple transport slots 210. The lifting mechanism 400 can drive the powder spraying baffles 410 to rise to abut against the magnetic core on the powder spraying table 200, so as to prevent the powder sprayed by the powder spraying gun 300 from entering the transport slot 210. The powder spraying baffles 410 can also be lowered so that the magnetic core transport mechanism 10 can be inserted into the transport slot 210 to place or pick up the magnetic core on the powder spraying table 200.

[0049] As can be seen from the above, the magnetic core spraying booth provided by the present invention, by setting a lifting mechanism 400 and a powder spraying baffle 410 below the powder spraying station 200, allows the powder spraying baffle 410 to rise to abut against the magnetic core during the spraying process, effectively preventing the powder sprayed by the powder spraying gun 300 from entering the transport tank 210. This solves the problem of powder easily entering and depositing in the transport tank 210 in the prior art, avoiding interference from powder accumulation in the transport tank 210 on the magnetic core transporting mechanism 10, and improving the operating efficiency and reliability of the equipment. At the same time, when the powder spraying baffle 410 descends, it provides sufficient space for the magnetic core transporting mechanism 10, allowing it to smoothly insert into the transport tank 210 to place or pick up the magnetic core. This design protects the transporting mechanism from powder contamination and extends the service life of the transporting mechanism. In addition, the powder spraying baffle 410 can not only effectively block powder from entering the transport tank 210 during the spraying process, but also support the magnetic core, thereby ensuring that the magnetic core remains stable during the spraying process and avoiding uneven spraying caused by the shaking or displacement of the magnetic core. This helps to improve the uniformity of the coating on the surface of the magnetic core, thereby improving the voltage resistance and performance stability of the magnetic core.

[0050] In one embodiment, the working cavity 110 includes a powder spraying cavity 111 and a clearance cavity 112 that are interconnected. The powder spraying cavity 111 is provided with a powder spraying platform 200. The powder spraying gun 300 can move to the powder spraying cavity 111 to spray powder onto the magnetic core on the powder spraying platform 200. The powder spraying gun 300 can also move to the clearance cavity 112 to avoid the magnetic core transport mechanism 10.

[0051] By adopting the above technical solution, the powder spraying gun 300 can spray the magnetic core within the powder spraying cavity 111, while making room for the magnetic core transport mechanism 10 within the clearance cavity 112. When the powder spraying gun 300 is within the clearance cavity 112, it will not interfere with the normal operation of the magnetic core transport mechanism 10, thus improving the overall operating efficiency of the equipment.

[0052] In one embodiment, a recovery funnel 140 communicating with the working cavity 110 is provided below the spraying machine housing 100. The recovery funnel 140 is connected to the cyclone separator 142 (as shown in the attached figure) via a recovery pipe 141. Figure 1 As shown), the cyclone separator 142 can extract powder from the working cavity 110 through the recovery pipe 141.

[0053] By employing the above technical solution, excess powder generated during the spraying process can be effectively recovered through the recovery funnel 140 and the cyclone separator 142, reducing powder waste. This not only improves material utilization but also reduces production costs.

[0054] Since multiple powder coating baffles 410 are required, the existing lifting mechanism 400 cannot guarantee the synchronous lifting and lowering of these baffles. Because each baffle 410 has a high degree of independent movement, some baffles may rise or fall at inconsistent speeds, resulting in height differences between them. This asynchrony can prevent the transport trough 210 from being completely closed or opened, affecting the coating effect and potentially causing powder to enter the transport trough 210, thus disrupting the normal operation of the magnetic core transport mechanism 10.

[0055] Therefore, please refer to the appendix. Figure 5 In one embodiment, the lifting mechanism 400 includes a connecting rod 420, a driving component 430, and a driven component 440. Each of the multiple powder spraying partitions 410 has a connecting hole on the side away from the powder spraying gun 300. The connecting rod 420 can pass through the connecting holes of the multiple powder spraying partitions 410 in sequence. The driven component 440 is connected to the output end of the driving component 430 and the connecting rod 420 respectively. The driving component 430 can drive the connecting rod 420 to rise or fall through the driven component 440.

[0056] Specifically, the number of connecting rods 420 can be adjusted as needed. For example, the number of connecting rods 420 can be two, three, etc. It can be understood that the number of connecting holes corresponds to the number of connecting rods 420, and all connecting rods 420 can pass through the corresponding connecting holes, thereby enhancing the stability of the overall structure.

[0057] Using the above technical solution, the connecting rod 420 passes through the connecting holes of multiple powder coating baffles 410 in sequence, ensuring that all powder coating baffles 410 can rise and fall synchronously. This design ensures the consistency of the powder coating baffles 410 during the rising or falling process, avoiding uneven coating or blockage of the transport trough 210 caused by uncoordinated movement of individual baffles.

[0058] Reference Appendix Figure 5 In one embodiment, the powder spraying baffle 410 has an abutment end 411 at one end facing the powder spraying gun 300, and the extension width of the abutment end 411 decreases from away from the powder spraying gun 300 to close to the powder spraying gun 300.

[0059] By adopting the above technical solution, by designing the extension width of the contact end 411 to be in a decreasing form, the contact area between the powder spraying partition 410 and the magnetic core is significantly reduced. The smaller contact area means that the amount of powder adhering to the back of the magnetic core is greatly reduced, avoiding the problem of uneven coating caused by powder contamination, thereby improving the coating quality after the magnetic core is flipped.

[0060] Reference Appendix Figure 6In one embodiment, the driven assembly 440 includes a driven rod 441 and a fixing plate 442. The driven rod 441 is located below a plurality of powder spraying partitions 410. There are two fixing plates 442, which are respectively located on opposite sides of the plurality of powder spraying partitions 410. The two fixing plates 442 are respectively provided with a first fixing hole and a second fixing hole. The first fixing hole is used for the opposite ends of the connecting rod 420 to pass through and be fixed, and the second fixing hole is used for the driven rod 441 to pass through and be fixed. The driving assembly 430 drives the connecting rod 420 to rise or fall through the driven rod 441.

[0061] Specifically, the number of driven rods 441 can be adjusted as needed. For example, the number of connecting rods 420 can be two or three. The two ends of all driven rods 441 are fixed to the two fixing plates 442 through the second fixing holes, thereby enhancing the stability of the overall structure.

[0062] With the above technical solution, the driven rod 441 is located below the powder spraying partition 410, while two fixing plates 442 are respectively set on opposite sides of the powder spraying partition 410. The first fixing hole and the second fixing hole on the fixing plate 442 are respectively used to fix the connecting rod 420 and the driven rod 441, thereby connecting multiple connecting rods 420, fixing plates 442 and driven rods 441 into a whole. This design further enhances the connection stability between components and ensures that the entire lifting mechanism 400 can operate smoothly during the working process.

[0063] Although a driven rod 441 is provided in the above embodiment, a single driven rod 441 may not provide sufficient support strength, especially when multiple powder spraying baffles 410 are raised and lowered simultaneously, the connecting rod 420 and the driven rod 441 may bear a large force. If the strength of the driven rod 441 is insufficient, it may bend or deform during the raising and lowering process, affecting the synchronous raising and lowering of the powder spraying baffles 410.

[0064] Therefore, in one embodiment, the driven component 440 further includes a first connecting plate 443, and the number of driven rods 441 is at least two. The at least two driven rods 441 are disposed through the first connecting plate 443, and the output end of the drive component 430 drives the driven rods 441 to rise or fall through the first connecting plate 443.

[0065] Using the above technical solution, the number of driven rods 441 is at least two, and at least two driven rods 441 are disposed through the first connecting horizontal plate 443. This design, through the combination of multiple driven rods 441 and the first connecting horizontal plate 443, significantly enhances the support strength of the driven assembly 440, ensuring that the connecting rod 420 can withstand greater forces during lifting and lowering, and avoiding bending or deformation.

[0066] In one embodiment, the drive assembly 430 includes a drive cylinder 431 and a drive rod 432. The drive rod 432 is vertically mounted inside the drive cylinder 431. There are two first connecting horizontal plates 443, and a fixing rod 444 is provided between the two first connecting horizontal plates 443. The end of the drive rod 432 facing the fixing rod 444 is provided with a connecting sleeve hole, and the fixing rod 444 is provided through the connecting sleeve hole.

[0067] Using the above technical solution, the end of the drive rod 432 facing the fixed rod 444 is provided with a connecting sleeve hole, and there are two first connecting cross plates 443, with a fixed rod 444 between the two first connecting cross plates 443, the fixed rod 444 passing through the connecting sleeve hole. This design, through the cooperation of the connecting sleeve hole and the fixed rod 444, ensures a firm and reliable connection between the drive rod 432 and the driven component 440.

[0068] In one embodiment, the driven assembly 440 further includes a second connecting horizontal plate 445, a buffer rod 446, and a buffer cylinder 447. At least two driven rods 441 are disposed through the second connecting horizontal plate 445. The buffer cylinder 447 is fixedly disposed below the second connecting horizontal plate 445. The buffer rod 446 is disposed inside the buffer cylinder 447. The second connecting horizontal plate 445 can descend with the driven rods 441 to abut against the buffer rod 446.

[0069] Specifically, the buffer cylinder 447 can be a rubber buffer cylinder, which utilizes the elasticity of rubber to absorb impact. This method is readily available, inexpensive, and easy to maintain and replace, but its buffering effect is not significant in high-precision and high-speed response applications. The buffer cylinder 447 can also be a hydraulic buffer cylinder, which utilizes the fluidity and incompressibility of hydraulic fluid to achieve buffering.

[0070] By employing the above technical solution, the combination of the buffer cylinder 447 and the buffer rod 446 effectively reduces the impact force between the driven rod 441 and the buffer rod 446 during rapid descent. This buffering effect not only protects the buffer rod 446 and the driven rod 441 but also reduces the impact on the entire device. By reducing impact and vibration, the buffering mechanism significantly improves the service life of the equipment and reduces its maintenance costs.

[0071] Reference Appendix Figure 7In one embodiment, the system further includes a first translation mechanism 500, a second translation mechanism 600, and a connecting plate 700. The first translation mechanism 500 is mounted on the spraying machine housing 100, which has a movable hole 130 communicating with the working cavity 110. The connecting plate 700 is movably mounted within the movable hole 130, and the two opposite ends of the connecting plate 700 are respectively connected to the first translation mechanism 500 and the second translation mechanism 600. The movement direction of the second translation mechanism 600 is perpendicular to the movement direction of the first translation mechanism 500. The powder spraying gun 300 is mounted on the second translation mechanism 600. The first translation mechanism 500 and the second translation mechanism 600 can drive the powder spraying gun 300 to move above the powder spraying table 200.

[0072] For details, please refer to the appendix. Figure 8 Both the first translation mechanism 500 and the second translation mechanism 600 include a translation motor 610, a lead screw 620, and a mounting plate 630. The output end of the translation motor 610 is connected to the lead screw 620, and the mounting plate 630 is threadedly connected to the lead screw 620. When the translation motor 610 drives the lead screw 620 to rotate, the mounting plate 630 can move on the lead screw 620. By setting the connecting plate 700 and the powder spraying gun 300 on the mounting plate 630, the movement of the powder spraying gun 300 on the powder spraying table 200 is realized.

[0073] By adopting the above technical solution, and by setting the first translation mechanism 500 outside the working cavity 110 and connecting it to the second translation mechanism 600 through the connecting plate 700 and the moving hole 130, the volume of the working cavity 110 is significantly reduced. The smaller volume of the working cavity 110 means that the powder diffusion range within it is smaller, reducing powder waste.
