Description

Technical Field

[0001] The present invention relates to the technical field of magnetic core production, and in particular to a high-efficiency magnetic core production system and a production process thereof. Background Art

[0002] The magnetic core, a core component of a transformer, is typically made of materials such as ferrite or silicon steel sheets. It possesses high magnetic permeability and is used to form a closed magnetic circuit. The design and manufacturing of the magnetic core requires extremely high precision to ensure that the transformer can effectively conduct the magnetic field and minimize energy loss during operation. As transformer performance requirements continue to increase, the processing technology of the magnetic core is also constantly improving. The production process of the magnetic core directly affects the overall performance of the transformer.

[0003] Existing magnetic core production equipment still has some defects. For example, the invention patent with publication number CN113724990B discloses a ferrite core inductor packaging production device, which includes a machine body, a rotating workbench, a tooling mechanism, and a lifting dispensing device. The tooling mechanism is arranged at the top of the rotating workbench and is located at the edge position. The tooling mechanism is evenly distributed at the top edge position of the rotating workbench. The lifting dispensing device is arranged at the top of the inner wall of the machine body and is located directly above the tooling mechanism. The limiting groove is opened at the top center position of the base. The cleaning device is arranged inside the base and is located at the top position. The pressing support device is arranged inside the base and is located at the position of the limiting groove. The present invention relates to the technical field of inductor processing equipment. The ferrite core inductor packaging production device achieves the effect of fast dispensing, can perform fast and uniform dispensing, is not easily disturbed by dust adhesion and external force impact, has strong adaptability, reduces limitations, has a good dispensing effect, and improves work efficiency and performance.

[0004] Although the above-mentioned device can achieve the function of uniform glue dispensing, when in use, the existing production equipment is not able to clamp the two magnetic cores and coat them with glue after dispensing. After the existing equipment bonds the two magnetic cores, the mechanical stress during rotation and coating will directly pull the two magnetic cores, which can easily lead to dislocation of the bonding interface and damage to the uncured glue layer. The rigid contact of the rotating mechanism forces the joint surfaces of the two magnetic cores to produce a displacement air gap, which ultimately leads to bonding failure, inductance fluctuation and the risk of voltage breakdown at the wrinkles of the insulating tape. The existing coating mechanism cannot adjust the tension of the tape during coating, and cannot clamp, lift and rotate the two magnetic cores to complete the coating at one time. Summary of the Invention

[0005] The present invention provides an efficient magnetic core production system and production process thereof, which solves the problems that the existing encapsulation mechanism cannot adjust the tension of the tape during encapsulation and cannot clamp, lift and rotate two magnetic cores to complete the encapsulation at one time.

[0011] As a preferred solution of the present invention, a liquid storage box is installed on the guide cylinder, a hose is connected to the liquid storage box, and the hose is connected to the glue dispensing machine.

[0012] As a preferred solution of the present invention, the first rotating assembly includes a rotating wheel fixedly connected to the key rod, a synchronous belt is installed on the rotating wheel, a second rotating ring is installed on the synchronous belt, a first fixed shaft is rotatably connected in the second rotating ring, a damping block is fixedly provided on the first fixed shaft, the damping block and the second rotating ring are in contact with each other, a second fixed shaft and a rotating plate are installed on the first fixed shaft, a second rotating shaft is rotatably installed on the rotating plate, and a pressure block is fixedly provided on the second rotating shaft.

[0013] As a preferred solution of the present invention, the reset assembly includes a mounting plate fixedly connected to the rotating plate, a vortex spring is installed between the mounting plate and the second rotating shaft, a first connecting belt and a second connecting belt are wound around the second rotating shaft, the second connecting belt is connected to the second rotating ring, and the connection method of the second side plate and the second rotating assembly is the same as the connection method of the first side plate and the first rotating assembly.

[0014] As a preferred solution of the present invention, the sliding assembly includes a first slide fixedly connected to the top plate, the first slide passes through the extension plate, a connecting plate is welded to the bottom of the first slide, and limiting sliders are slidably installed on both sides of the extension plate, an elastic band is arranged between the limiting slider and the support plate, the first side plate and the second side plate are both passed through the corresponding limiting sliders, and a first spring is installed between the limiting slider and the first side plate and the second side plate.

[0015] A magnetic core production process comprises the following steps: S1: The guide cylinder and the second connecting plate are used to guide the first magnetic core, so that the first magnetic core is conveyed to one side of the first rotating ring through the third conveyor belt. At this time, the electric push rod is shortened to make the top plate drive the dispensing machine and the three dispensing heads below it to move downward to dispense glue on the contact surface of the horizontal first magnetic core; S2: After dispensing is completed, the electric push rod is reset, and the first motor drives the rubber drive wheel to rotate, rotating the first rotating ring outside the fixed plate 120 degrees counterclockwise, so that the first magnetic core is transported to the bottom of the connecting frame and the second conveyor belt. The electric push rod is shortened, and the second conveyor belt rotates in conjunction with the second conveyor belt to transport the second magnetic core to the top of the first magnetic core, completing the alignment and pressing of the two magnetic cores. S3: Rotate the first rotating ring 120° counterclockwise. During the rotation, the electric push rod is lifted and reset again. During the upward movement of the electric push rod, it acts on the first side plate and the second side plate through the sliding assembly, so that the first side plate and the second side plate first move away from each other, and then move upward synchronously until the two pressed magnetic cores move to the rubber-coated area, and the electric push rod is shortened again. S4: When the electric push rod is shortened, the sliding assembly will reset the first side plate and the second side plate. After the first and second side plates are reset, the two magnetic cores are automatically clamped, and the second motor drives the key rod to rotate. The key rod first drives the first rotating assembly and the second rotating assembly to rotate, and then delays the action on the reset assembly, so that the two magnetic cores are lifted and automatically encapsulated with rubber.

[0016] The working principle and beneficial effects of the present invention are: 1. Through the electric push rod, top plate, first conveyor belt, second conveyor belt and third conveyor belt, the device can complete the steps of dispensing glue, aligning and pressing and encapsulating glue for two magnetic cores at one time when working. The first magnetic core is first conveyed to one side opening of the first rotating ring through the third conveyor belt. The electric push rod is shortened to perform the dispensing glue on the three contact surfaces of the first magnetic core. The first rotating ring is then rotated to convey the first magnetic core after dispensing glue to the position below the second magnetic core. The two magnetic cores are aligned and pressed together through the second conveyor belt. The two pressed magnetic cores are then conveyed to the encapsulation area for encapsulation through the first rotating assembly and the second rotating assembly, thereby enhancing the convenience of the device when used.

[0017] When the second motor drives the key rod to rotate, it will first drive the second rotating ring to rotate through the rotating wheel and the synchronous belt. The second rotating ring will drive the first fixed shaft, the second fixed shaft and the rotating plate to rotate through the damping block. At this time, the limit block slides in the rotating groove. When the limit block moves to the limit position, the rotating plate cannot rotate further. The second rotating ring slides on the outside of the first fixed shaft, and the second connecting belt that was originally loose on the second rotating ring is gradually tightened, and pulls the first connecting belt wound on the second rotating shaft. The first connecting belt drives the second rotating shaft to rotate between the rotating plate and the mounting plate, thereby driving the pressing block to rotate. Since the first rotating assembly and the second rotating assembly have the same structure, the above steps are generally applicable to the second rotating assembly. The pressing block will drive the two magnetic cores in the compressed state to rotate, so that the device can clamp, lift and rotate the two magnetic cores to complete the encapsulation work at one time, thereby improving the working efficiency of the device.

[0018] 3. The tensioning assembly realizes the function of adjusting the tension of the tape during rubber coating. By rotating the rubber block, the screw drives the square nut and the rubber block to rise and fall, thereby changing the degree of compression between the rubber block and the first rotating shaft, and then changing the rotational resistance of the first rotating shaft and the reel. Since the rubber coating method of the device is to rotate the two magnetic core bodies to coat the rubber, the rubber coating tension adjustment function can be achieved by changing the rotational resistance of the tape reel, which solves the problem that the existing magnetic core rubber coating mechanism cannot adjust the tension of the tape during rubber coating.

DETAILED DESCRIPTION

[0022] The following will be combined with the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making any creative efforts are within the scope of protection of the present invention.

[0023] Example 1 like Figures 1-12As shown, this embodiment proposes an efficient production system for magnetic cores, including a base 1, a support plate 2 and a fixed disk 3, a first motor 5 is installed on the fixed disk 3, a rubber driving wheel 6 is fixedly connected above the output shaft of the first motor 5, a first rotating ring 4 is abutted on the outer side of the rubber driving wheel 6, the rubber driving wheel 6 is driven to rotate by the first motor 5, and the first rotating ring 4 is driven to rotate, and the first rotating ring 4 can complete the position switching function of the first magnetic core every 120° rotation, a first connecting plate 8 and a second connecting plate 18 are installed on the support plate 2, a first conveyor belt 9 and a bracket 10 are installed on the first connecting plate 8, the first conveyor belt 9 is used to convey the magnetic cores that have been coated with rubber, a reel 11 and a tensioning assembly 12 are installed on the bracket 10, the tensioning assembly 12 can adjust the tension during coating, a guide cylinder 17 and a third conveyor belt 19 are installed on the second connecting plate 18, and the third The conveyor belt 19 is used to transport the first magnetic core to the dispensing area, and an electric push rod 13 is installed between the fixed disk 3. A top plate 14 is provided on the top of the electric push rod 13. A glue dispenser 20, a connecting frame 15 and a sliding assembly 28 are installed on the top plate 14. The electric push rod 13 is not only used for dispensing, but also can clamp the two magnetic cores through the sliding assembly 28 after the dispensing is completed. A second conveyor belt 16 is installed on the connecting frame 15, a glue dispenser 21 is installed on the glue dispenser 20, an extension plate 31 is installed on the sliding assembly 28, and a first side plate 23, a first rotating assembly 25, a second side plate 35 and a second rotating assembly 27 are provided on the extension plate 31. A reset assembly 26 is installed on the first rotating assembly 25 and the second rotating assembly 27. A second motor 24 is installed on the first side plate 23, and a key rod 29 is fixedly connected to the output shaft of the second motor 24. Figure 2 and Figure 5 It can be seen that when the second motor 24 drives the key rod 29 to rotate, it will first drive the first rotating component 25 and the second rotating component 27 to rotate, and then delay the reset component 26 acting on the first rotating component 25 and the second rotating component 27, so that the device can first lift the two magnetic cores and then rotate the two magnetic cores for encapsulation after clamping the two magnetic cores.

[0024] Example 2 like Figures 1-12 As shown, based on the same concept as the above-mentioned embodiment 1, this embodiment also proposes an efficient production system for magnetic cores.

[0025] In this embodiment, the base 1, the support plate 2, the fixed plate 3, the first connecting plate 8 and the second connecting plate 18 are fixedly connected to form an integral structure. The upper surface of the fixed plate 3 and the first rotating ring 4 are flush. The first rotating ring 4 is provided with an opening 7 for the movement of the first magnetic core. The extension plate 31 is fixedly connected to the fixed plate 3. The three openings 7 are respectively used for feeding the first magnetic core, pressing the two magnetic cores together, and discharging the two magnetic cores after being coated with glue.

[0026] In this embodiment, the tensioning assembly 12 includes a first rotating shaft 1201 fixedly connected to the reel 11, a rubber block 1205 is abutted against the bottom of the first rotating shaft 1201, a square nut 1204 is fixedly connected to the bottom of the rubber block 1205, the square nut 1204 is internally threaded with a screw 1203, and a rotating block 1202 is fixedly provided at the bottom of the screw 1203. By rotating the rotating block 1202, the screw 1203 drives the square nut 1204 to rise and fall, thereby changing the degree of compression between the rubber block 1205 and the first rotating shaft 1201, and then changing the rotational resistance of the first rotating shaft 1201, so as to subsequently adjust the tension of the tape when the reel 11 is rubber-wrapped.

[0027] In this embodiment, the rotating block 1202 and the first rotating shaft 1201 are all rotatingly connected to the bracket 10, and the rubber block 1205 and the square nut 1204 are all slidingly connected to the bracket 10. The square nut 1204 can only move up and down, so that the rubber block 1205 can remain fixed after being adjusted to the appropriate position, thereby ensuring the overall stability of the device.

[0028] In this embodiment, the second conveyor belt 16 is symmetrically distributed on both sides of the connecting frame 15, and rubber protrusions 22 are provided on the tracks of the second conveyor belt 16. When the second conveyor belt 16 rotates, the rubber protrusions 22 can provide resistance when conveying the second magnetic core, thereby ensuring that the second magnetic core can be stably aligned and pressed with the first magnetic core.

[0029] In this embodiment, a liquid storage box 30 is installed on the guide cylinder 17, and a hose 34 is connected to the liquid storage box 30. The hose 34 is connected to the dispensing machine 20. Each dispensing head 21 corresponds to one of the contact surfaces of the first magnetic core, thereby ensuring that the glue fully covers the bonding area and eliminating the risk of air gap generation between the two magnetic cores.

[0030] In this embodiment, the first rotating assembly 25 includes a rotating wheel 2501 fixedly connected to the key rod 29, a synchronous belt 2502 is installed on the rotating wheel 2501, a second rotating ring 2503 is installed on the synchronous belt 2502, a first fixed shaft 2504 is rotatably connected in the second rotating ring 2503, a damping block 2505 is fixedly provided on the first fixed shaft 2504, the damping block 2505 and the second rotating ring 2503 abut against each other, a second fixed shaft 33 and a rotating plate 2506 are installed on the first fixed shaft 2504, a second rotating shaft 2507 is rotatably installed on the rotating plate 2506, a pressure block 2508 is fixedly provided on the second rotating shaft 2507, a limiting block 36 is fixedly connected to the second fixed shaft 33, and a space for the limiting block is provided on the first side plate 23. The positioning block 36 rotates the rotating groove 32, and when the key rod 29 rotates, it will first drive the second rotating ring 2503 to rotate through the rotating wheel 2501 and the synchronous belt 2502, and the second rotating ring 2503 will drive the first fixed shaft 2504, the second fixed shaft 33 and the rotating plate 2506 to rotate through the damping block 2505. The limit block 36 slides in the rotating groove 32. When the limit block 36 cannot move further, the rotating plate 2506 cannot rotate further. The second rotating ring 2503 slides on the outside of the first fixed shaft 2504. The second rotating ring 2503 can subsequently drive the second rotating shaft 2507 to rotate on the rotating plate 2506, causing the pressing block 2508 to rotate. The pressing block 2508 will drive the two magnetic cores in the compressed state to rotate, so that the encapsulation work can be completed at one time.

[0031] In this embodiment, the reset assembly 26 includes a mounting plate 2601 fixedly connected to the rotating plate 2506, a vortex spring 2602 is installed between the mounting plate 2601 and the second rotating shaft 2507, a first connecting belt 2603 and a second connecting belt 2604 are wound around the second rotating shaft 2507, and the second connecting belt 2604 is connected to the second rotating ring 2503. After the rotating plate 2506 lifts the two magnetic cores, the second rotating ring 2503 continues to rotate, and the second connecting belt 2604 that was originally loose on the second rotating ring 2503 is gradually tightened, and pulls the first connecting belt 2603 wound around the second rotating shaft 2507, and the second connecting belt 2604 is connected to the second rotating ring 2503. A connecting belt 2603 drives the second rotating shaft 2507 to rotate between the rotating plate 2506 and the mounting plate 2601. The vortex spring 2602 facilitates the subsequent resetting of the second rotating shaft 2507, thereby driving the pressure block 2508 to rotate. The connection method between the second side plate 35 and the second rotating component 27 is the same as the connection method between the first side plate 23 and the first rotating component 25. The reset component 26 on the first rotating component 25 is suitable for the second rotating component 27. The pressure block 2508 cooperates with the second rotating component 27 to drive the two magnetic cores in the compressed state to rotate, so that the device can clamp, lift and rotate the two magnetic cores to complete the encapsulation work at one time.

[0032] In this embodiment, the sliding assembly 28 includes a first slide 2801 fixedly connected to the top plate 14, the first slide 2801 passes through the extension plate 31, a connecting plate 2804 is welded to the bottom of the first slide 2801, and limit sliders 2805 are slidably installed on both sides of the extension plate 31. An elastic band 2802 is provided between the limit slider 2805 and the support plate 2, the first side plate 23 and the second side plate 35 are both provided through the corresponding limit sliders 2805, and a first spring 2803 is installed between the limit slider 2805 and the first side plate 23 and the second side plate 35. Figure 1 、 Figure 2 、 Figure 9 and Figure 10 As shown, when the first slide 2801 is pulled upward, the inclined surface of the first slide 2801 will first abut against the limiting slider 2805, the elastic band 2802 on the limiting slider 2805 will be stretched, and the first side plate 23 and the second side plate 35 will move away from each other. As the elastic band 2802 is gradually tightened, the connecting plate 2804 will gradually push the limiting slider 2805 upward, so that the first side plate 23 and the second side plate 35 will be pushed upward after being stretched, so that the two magnetic cores that have been pressed together can enter the clamping area and wait for the rubber coating.

[0033] Specifically, the present invention is a high-efficiency production system and production process of magnetic cores. First, as Figure 1 、 Figure 4 、 Figure 7 、 Figure 8 and Figure 11 As shown, the base 1 and the support plate 2 are used to support the entire device. The first magnetic core is guided by the guide cylinder 17 and the second connecting plate 18, so that the first magnetic core is transported to one side of the first rotating ring 4 through the third conveyor belt 19 ( Figure 4 As can be seen in the figure), the electric push rod 13 is shortened so that the top plate 14 drives the glue dispenser 20 and the three glue dispensers 21 below it to move downward, and glue is applied to the three contact surfaces of the horizontally placed first magnetic core. After the glue is applied, the electric push rod 13 is reset, and the first motor 5 drives the rubber drive wheel 6 to rotate. The rubber drive wheel 6 abuts against the first rotating ring 4 and drives the first rotating ring 4 to rotate, rotating the first rotating ring 4 outside the fixed plate 3 counterclockwise by 120 degrees, so that the first magnetic core is conveyed to the bottom of the connecting frame 15 and the second conveyor belt 16, as shown in FIG. Figure 1 As shown, the electric push rod 13 is shortened and the second conveyor belt 16 is rotated to convey the second magnetic core to the top of the first magnetic core, thereby completing the alignment and pressing of the two magnetic cores.

[0034] like Figures 1-6 and Figures 9-12 As shown, the first rotating ring 4 is rotated 120 degrees counterclockwise. During the rotation, the electric push rod 13 is lifted and reset again. During the upward movement of the electric push rod 13, as shown in FIG. Figure 2 and Figure 10 As shown, the first slide 2801 is pulled upward, and the inclined surface of the first slide 2801 first abuts the limiting slider 2805. The elastic band 2802 on the limiting slider 2805 is stretched, and the first side plate 23 and the second side plate 35 move away from each other. The elastic band 2802 is gradually tightened. When the bottoms of the first and second side plates 23 and 35 are in contact with the connecting plate 2804, the limiting slider 2805 of the connecting plate 2804 pushes upward, causing the first and second side plates 23 and 35 to move in opposite directions and then be pushed upward synchronously, so that the two pressed magnetic cores can be smoothly entered into the clamping area to wait for the rubber coating. The starting end of the rubber coating is positioned and attached to the designated area on the surface of the magnetic core by an external robotic arm end effector or manual operation. At this time, the electric push rod 13 can be shortened, and the first and second side plates 23 and 35 are reset and clamped together by the first spring 2803 and the elastic band 2802. At this time, the magnetic cores can be lifted and then rotated to start the rubber coating.

[0035] When encapsulating, Figure 1-Figure 5 、 Figure 11 and Figure 12As shown, when the second motor 24 drives the key rod 29 to rotate, it will first drive the second rotating ring 2503 to rotate through the synchronous belt 2502 on the rotating wheel 2501, and the second rotating ring 2503 will drive the first fixed shaft 2504, the second fixed shaft 33 and the rotating plate 2506 to rotate through the damping block 2505, and the limit block 36 slides in the rotating groove 32. When the limit block 36 moves to the extreme position in the rotating groove 32, the second fixed shaft 33 and the rotating plate 2506 cannot rotate further. At this time, the rotating plate 2506 lifts the two magnetic cores. Since the second rotating ring 2503 and the first fixed shaft 2504 are rotationally connected, the rotating plate 2506 is only indirectly driven to rotate through the damping block 2505. When the second fixed shaft 33 and the first fixed shaft 2504 cannot rotate further, the second rotating ring 2503 and the first fixed shaft 2504 are rotationally connected. The second rotating ring 2503 overcomes the resistance between it and the damping block 2505, slides on the outside of the first fixed shaft 2504, and after the two magnetic cores are lifted, the second connecting belt 2604 that was originally loose on the second rotating ring 2503 is gradually tightened, and pulls the first connecting belt 2603 wound on the second rotating shaft 2507. The first connecting belt 2603 drives the second rotating shaft 2507 to rotate between the rotating plate 2506 and the mounting plate 2601, thereby driving the pressing block 2508 to rotate. Since the first rotating component 25 and the second rotating component 27 have the same structure, the above steps are generally applicable to the second rotating component 27. The pressing block 2508 will drive the two magnetic cores in the compressed state to rotate, so that the device can clamp, lift and rotate the two magnetic cores to complete the encapsulation work at one time. The tensioning assembly 12 is used to adjust the tension during the laminating process. By rotating the rubber block 1205, the screw 1203 drives the square nut 1204 and the rubber block 1205 upward and downward, thereby changing the degree of compression between the rubber block 1205 and the first rotating shaft 1201, and thus the rotational resistance of the first rotating shaft 1201 and the reel 11 on the bracket 10. Because the laminating method of this device is to rotate the two magnetic core bodies, the laminating tension can be adjusted by changing the rotational resistance of the tape reel 11 (that is, the tension required during unwinding). After the laminating is completed, the first side plate 23 and the second side plate 35 are again opened in the same manner as described above, and the two completed magnetic cores are transported to the assembly area via the first connecting plate 8 and the first conveyor belt 9.

[0036] The above are only preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.

10. A magnetic core production process, using the magnetic core efficient production system according to claim 1, characterized in that: The steps include: S1: The guide cylinder (17) and the second connecting plate (18) are used to guide the first magnetic core so that the first magnetic core is transported to one side of the first rotating ring (4) through the third conveyor belt (19). At this time, the electric push rod (13) is shortened to allow the top plate (14) to drive the dispensing machine (20) and the three dispensing heads (21) below it to move downward to dispense glue on the three contact surfaces of the horizontally placed first magnetic core; S2: After the dispensing is completed, the electric push rod (13) is reset, and the first motor (5) drives the rubber driving wheel (6) to rotate, and the first rotating ring (4) outside the fixed disk (3) is rotated 120 degrees counterclockwise, so that the first magnetic core is transported to the bottom of the connecting frame (15) and the second conveyor belt (16), and the electric push rod (13) is shortened, and the second conveyor belt (16) is rotated to transport the second magnetic core to the top of the first magnetic core, completing the alignment and pressing of the two magnetic cores; S3: The first rotating ring (4) is rotated counterclockwise by 120°. During the rotation, the electric push rod (13) is lifted and reset again. During the upward movement of the electric push rod (13), the sliding assembly (28) acts on the first side plate (23) and the second side plate (35), so that the first side plate (23) and the second side plate (35) first move away from each other and then move upward synchronously until the two magnetic cores that have been pressed together move to the rubber-coated area, shortening the electric push rod (13) again. S4: When the electric push rod (13) is shortened, the first side plate (23) and the second side plate (35) are reset through the sliding assembly (28). After the first side plate (23) and the second side plate (35) are reset, the two magnetic cores are automatically clamped and the key rod (29) is driven to rotate by the second motor (24). The key rod (29) first drives the first rotating assembly (25) and the second rotating assembly (27) to rotate, and then delays the action on the reset assembly (26), so that the two magnetic cores are lifted and automatically coated.
