Description

Technical Field

[0001] This invention relates to the field of magnetic core manufacturing technology, specifically to a stacking device for combined magnetic core manufacturing. Background Technology

[0002] Magnetic core: A magnetic core is a sintered magnetic metal oxide composed of various iron oxide mixtures. For example, manganese-zinc ferrite and nickel-zinc ferrite are typical magnetic core materials. Manganese-zinc ferrite has the characteristics of high permeability and high magnetic flux density, and also has the characteristic of low loss.

[0003] In the process of magnetic core processing and production, a lamination device is needed to stack multiple magnetic core sheets. Because the magnetic cores need to maintain high precision after lamination, precise stacking is required. Current equipment has the following problems when laminating and applying adhesive: First, the lamination rate is slow. If fast-drying adhesive is used during slow processing, it will result in low bonding strength between the magnetic cores after lamination.

[0004] Second, glue leakage after bonding. After bonding, existing equipment generally uses a press to increase the bonding strength between the magnetic cores. However, using a press will greatly increase the probability of glue leakage.

[0005] Third, uneven glue application. Due to uneven glue application, the bonding strength between magnetic cores is also uneven after the glue is applied in the existing equipment. Summary of the Invention

[0006] To address the shortcomings of existing technologies, this invention provides a stacking device for producing combined magnetic cores, which solves the problems mentioned in the background section.

The sliding assembly is operable to allow the adhesive application assembly and the pressing assembly to act on the magnetic core stacking assembly respectively, thereby achieving reciprocating processing.

[0008] Preferably, the sliding assembly includes a bottom plate and a top plate. The top plate can actively slide relative to the bottom plate. The top plate has three through holes running vertically through it, and the bottom plate has one through hole running vertically through it at its center.

The pressing assembly is installed on the top plate and corresponds to the hole in the middle.

[0009] Preferably, the magnetic core stacking assembly includes a slide, a magnetic core stage, and a displacement stage. The slide is installed in the housing assembly and can move linearly up and down inside the housing. The magnetic core stage is fixed on the slide. The displacement stage is installed in the magnetic core stage and can move up and down along the magnetic core stage. The displacement stage cooperates with the magnetic core stage to stack magnetic cores, and the displacement stage can push the magnetic cores into the holes in the base plate.

[0010] Preferably, the adhesive application assembly includes an electric pump, a hose, and an application table. The application table is installed in a hole in the top plate and can rotate autonomously relative to the hole. The interior of the application table is a hollow structure, and the hose is rotatably and sealed to it, with the two having a spatial connection. The electric pump is installed at the upper end of the hose and is used to pump adhesive into the internal space of the hose.

[0011] Preferably, the longitudinal section of the glue application table is circular, the bottom is a planar structure, the bottom surface of the glue application table is provided with a ring of glue holes that communicate with the top, and scrapers are fixed between two adjacent glue holes on the bottom surface of the glue application table.

[0012] Preferably, the pressure-compression assembly includes a mounting frame and an electrically controlled high-pressure jet pipe. The mounting frame is installed on the top plate and corresponds to the central hole. The electrically controlled high-pressure jet pipe is fixed on the mounting frame, and the outer ring of the mounting frame is provided with an exhaust hole.

[0013] Preferably, a core placement container is installed in the last remaining hole on the top plate for stacking cores.

[0014] Preferably, the base plate is provided with two slide rails, and the bottom surface of the top plate is fixed with two matching slide rails. After the two are connected, the top plate and the base plate fit together. A motor a is fixedly installed at the middle position of the front and rear sides of the base plate. A gear a is fixedly installed on the output shaft of the motor a. A toothed plate is installed on the side of the top plate, and the gear meshes with the toothed plate.

[0015] Preferably, the housing assembly includes an outer shell and uprights. The upper end of the outer shell is fixed to the bottom plate, and the uprights are fixed between the inner bottom wall of the outer shell and the bottom wall of the bottom plate. Multiple uprights are provided. The outer ring of the slide table slides in cooperation with multiple uprights. A motor b is installed on the slide table, and a rubber wheel a is installed on the output shaft of the motor b for engaging the uprights to realize the sliding of the slide table.

[0016] Preferably, a motor d is fixedly installed on the top plate, a gear b is fixedly installed on the output shaft of the motor d, a gear ring is fixed on the outer ring of the glue application table, and the gear b meshes with the gear ring.

[0017] Compared with the prior art, the present invention has the following beneficial effects: 1. This modular magnetic core production stacking device, by setting up a sliding component, can respectively align the glue application component, the pressing component, and the magnetic core placement tank with the magnetic core stacking component when sliding on the top plate. Therefore, it can continuously achieve magnetic core bonding and stacking, resulting in high processing efficiency. The magnetic core is bonded in a hole-to-hole manner, resulting in higher concentricity. The holes are determined according to the specifications of the magnetic core, which is more precise than the gripping of a robotic arm. Therefore, it can achieve high-efficiency and precise processing of magnetic core stacks.

[0018] 2. This modular magnetic core production stacking device, by setting up a magnetic core stacking assembly, allows the magnetic cores to be gradually stacked as they fall onto the displacement stage. As the top plate slides, the height of the displacement stage gradually changes downward, maintaining precise adhesive thickness and stacking accuracy. After stacking to a certain height, the height of the magnetic core stage is changed by a slide table. After stacking is complete, the slide table can also remove the magnetic cores. Therefore, the control precision is higher, and the distance between any two magnetic cores can be made to be basically the same.

[0019] 3. This modular magnetic core production stacking device, by setting up an adhesive application component, uses a rotary adhesive application table to evenly apply adhesive to the magnetic core. By controlling the distance between the magnetic core and the adhesive application table, the adhesive thickness can be controlled. Therefore, during bonding, the adhesive is even and the bonding is uniform, and there will be no problem of excessive adhesive in some areas, resulting in overflow.

[0020] 4. The stacking device for the combined magnetic core production uses a pressing component to apply pressure to the magnetic core after bonding. The airflow is discharged through the exhaust port, and the pressing rate is fast. Bonding can be completed in one press, and the solidification speed of the adhesive is increased.

If the combination of technical solutions is contradictory or impossible to implement, such a combination of technical solutions should be considered non-existent and not within the scope of protection claimed in this application.

[0027] like Figures 1-10As shown, a composite magnetic core production stacking device includes a magnetic core stacking assembly 1 and a sliding assembly 2. An adhesive application assembly 3 and a pressing assembly 4 are respectively installed on the sliding assembly 2. The device also includes a housing assembly 5 for mounting and supporting the magnetic core stacking assembly 1. The sliding assembly 2 can operate to allow the adhesive application assembly 3 and the pressing assembly 4 to act on the magnetic core stacking assembly 1 respectively, thereby realizing reciprocating processing.

[0028] Existing equipment typically uses a circulating system for stacking. However, this system requires specialized piping to supply the adhesive, and the supply of air and electrical circuits is difficult to achieve, resulting in very low efficiency during actual processing. It essentially requires reciprocating operation, wasting the efficiency of one cycle. In this solution, a sliding component 2 that can reciprocate and change relative to each other can be used to apply the adhesive to the coating component 3 and the pressing component 4 to the magnetic core stacking component 1 during reciprocating movement. Under the high-frequency operation of the motor, high-efficiency reciprocating processing can be achieved.

[0029] In an optional embodiment, the sliding component 2 includes a bottom plate 201 and a top plate 202. The top plate 202 can actively slide relative to the bottom plate 201. The top plate 202 is provided with three through holes, and the bottom plate 201 is provided with a through hole at its center. When the top plate 202 moves back and forth, the three holes on the top can correspond to one hole on the bottom. The magnetic core stacking assembly 1 is located below the base plate 201 and corresponds to the hole in the base plate 201. The adhesive application assembly 3 is installed on the top plate 202 and corresponds to one of the holes on both sides. The pressing assembly 4 is installed on the top plate 202 and corresponds to the hole in the middle.

[0030] In this embodiment, grease needs to be applied between the base plate 201 and the top plate 202. The holes on the top plate 202 have the same diameter as the holes on the base plate 201, and the upper and lower ends of any hole are chamfered to increase the smoothness. The holes on the top plate 202 and the base plate 201 are matched with the diameter of the magnetic core. The diameter of the magnetic core needs to be slightly smaller than the diameter of the hole to facilitate direct drop. The hole diameter can be changed later according to the diameter of the magnetic core.

[0031] In an optional embodiment, the magnetic core stacking assembly 1 includes a slide 101, a magnetic core stage 102, and a displacement stage 103. The slide 101 is installed in the housing assembly 5 and can move linearly up and down within the housing assembly 5. The magnetic core stage 102 is fixed on the slide 101. The displacement stage 103 is installed in the magnetic core stage 102 and can move up and down along the magnetic core stage 102. The displacement stage 103 cooperates with the magnetic core stage 102 to stack magnetic cores, and the displacement stage 103 can push the magnetic cores into the holes of the base plate 201.

[0032] In this embodiment, the magnetic core stage 102 is an assembly for placing magnetic cores. It has a tubular structure with the center pointing downwards, which facilitates subsequent venting. The displacement stage 103 is used to ensure that the magnetic core above it is in close contact with the upper surface of the base plate 201, and is also used to precisely adjust the height of the magnetic core, which facilitates subsequent adjustment of the adhesive thickness.

[0033] In an optional embodiment, the adhesive application assembly 3 includes an electric pump 301, an adhesive tube 302, and an adhesive application table 303. The adhesive application table 303 is installed in a hole in the top plate 202 and can rotate autonomously relative to the hole. The interior of the adhesive application table 303 is a hollow structure, and the adhesive tube 302 is sealed and rotatably connected to it, with the two having spatial communication. The electric pump 301 is installed at the upper end of the adhesive tube 302 and is used to pump adhesive into the internal space of the adhesive tube 302.

[0034] In this embodiment, the electric pump 301 is an electric pump used to extract adhesive from the adhesive tank. The adhesive tube 302 serves to transfer the adhesive. In another embodiment, a heating coil can be wound around the outside of the adhesive tube 302 to heat the internally pumped adhesive, thereby adapting to adhesives that require heating for stacking. A bearing is installed at the connection between the coating table 303 and the top plate 202. Under the action of an electrical signal, the electric pump 301 can pump a certain flow rate of adhesive, and this amount can be adjusted according to the actual electrical signal.

[0035] In an optional embodiment, the adhesive application table 303 has a circular longitudinal section and a planar bottom structure. The bottom surface of the adhesive application table 303 is provided with a ring of adhesive holes 304 that communicate with the top. A scraper 305 is fixed between two adjacent adhesive holes 304 on the bottom surface of the adhesive application table 303.

[0036] In this embodiment, when the adhesive is discharged from the bottom of the coating table 303, the adhesive can be squeezed onto the magnetic core. Then, by controlling the rotation of the coating table 303, the adhesive can be evenly spread on the magnetic core. The scraper 305 can spread the adhesive evenly so that the surface of a magnetic core is basically covered with adhesive, or leave a certain margin at the edge to avoid adhesive leakage later.

[0037] In an optional embodiment, the pressure assembly 4 includes a mounting bracket 401 and an electrically controlled high-pressure jet pipe 402. The mounting bracket 401 is mounted on the top plate 202 and corresponds to the central hole. The electrically controlled high-pressure jet pipe 402 is fixed on the mounting bracket 401. The outer ring of the mounting bracket 401 is provided with a ring of exhaust holes 403.

[0038] In this embodiment, the electrically controlled high-pressure jet pipe 402 operates periodically to eject high-pressure gas. After the magnetic core is stacked, the electrically controlled high-pressure jet pipe 402 is opened instantaneously. The ejected high-pressure gas can increase the compressibility of the magnetic core. However, the jetting is not continuous. Each time, it is performed at a certain frequency.

[0039] In an alternative embodiment, a core placement container 203 is installed in the last remaining hole on the top plate 202 for stacking cores.

[0040] In this embodiment, the magnetic core placement container 203 is used to place the magnetic cores in a stacked manner. When it is necessary to put down the magnetic core, gravity can be used to place it naturally on the glued magnetic core. Alternatively, it can be supplied pneumatically or electrically, depending on the existing equipment.

[0041] In an optional embodiment, the base plate 201 is provided with two slide rails 204, and the bottom surface of the top plate 202 is fixed with two slide rails 205 that cooperate with it. After the two are connected, the top plate 202 and the base plate 201 are in contact. A motor a is fixedly installed at the middle position of the front and rear sides of the base plate 201. A gear a is fixedly installed on the output shaft of the motor a. A toothed plate is installed on the side of the top plate 202, and the gear meshes with the toothed plate.

[0042] In this embodiment, the grease between the base plate 201 and the top plate 202 can ensure that the two maintain precision during long-term cyclic sliding.

[0043] In an optional embodiment, the housing assembly 5 includes a housing 501 and columns 502. The upper end of the housing 501 is fixed to the base plate 201, and the columns 502 are fixed between the inner bottom wall of the housing 501 and the bottom wall of the base plate 201. Multiple columns 502 are provided. The outer ring of the slide table 101 is slidably engaged with multiple columns 502. A motor b is installed on the slide table 101, and a rubber wheel a is installed on the output shaft of the motor b for engaging the columns 502 to realize the sliding of the slide table 101. A motor c is fixedly mounted on the bottom of the magnetic core stage 102, and a rubber wheel b is fixedly mounted on the output shaft of the motor c for engaging and driving the displacement stage 103.

[0044] In this embodiment, the column 502 is made of metal, and the rubber wheel a is set to fit against the column 502. When it rotates, it can engage the column 502, thereby changing the position of the slide table 101. The interior of the housing 501 is also equipped with an adhesive tank and a pneumatic device. The adhesive tank is used to store adhesive, and the pneumatic device is used to supply air to the electrically controlled high-pressure jet pipe 402. The circuit board, control chip, and various modules of the equipment are all installed inside the housing 501 and operate according to the predetermined electrical settings.

[0045] In an optional embodiment, a motor d is fixedly mounted on the top plate 202, a gear b is fixedly mounted on the output shaft of the motor d, and a gear ring is fixed on the outer ring of the glue application table 303, with the gear b meshing with the gear ring.

[0046] In use, the magnetic cores to be stacked are first placed in the magnetic core placement tank 203 in a stacked manner. As the top plate 202 moves back and forth, when the magnetic core placement tank 203 corresponds to the hole in the bottom plate 201, a magnetic core can be placed downwards. When the top plate 202 slides, the glue application component 3, the pressing component 4 and the magnetic core placement tank 203 can be respectively aligned with the magnetic core stacking component 1. Glue application stage: When a magnetic core is placed on the displacement stage 103, the glue application component 3 moves to the magnetic core and begins to apply glue to the magnetic core. The electric pump 301 pumps the glue into the glue application stage 303, so that the glue can be applied to the magnetic core from the bottom of the glue application stage 303. The glue application stage 303 is rotated and the scraper 305 can spread the glue evenly on the magnetic core. Stacking stage: The top plate 202 then continues to move, and controls one of the magnetic cores to fall, so that the magnetic core falls onto the magnetic core that has been coated with glue. Due to the hole-to-hole constraint, the two maintain a high degree of concentricity after the magnetic core falls in. When the magnetic core falls onto the displacement stage 103, it can be gradually stacked. As the top plate 202 slides, the displacement stage 103 will gradually change its height downward, which can maintain the precise glue thickness and stacking accuracy. Pressing stage: After the magnetic core is bonded, pressure is applied to it using high-pressure airflow. The airflow is discharged through the exhaust port 403. The pressure application rate is fast, and the bonding can be completed in one press.

[0047] After pressing one magnetic core stack, the magnetic core above is coated with glue, stacked, and pressed again. This process is repeated to achieve automated reciprocating magnetic core stacking. Finally, after stacking the sheets to a certain height, the height of the magnetic core stage 102 is changed by using the slide 101. After the stacking is completed, the slide 101 can also remove the magnetic core.
