Description

Technical Field

[0001] This utility model relates to the field of magnetic winding cable arrangement, specifically to a magnetic winding cable arrangement device for common mode inductors. Background Technology

[0002] As electronic devices become smaller and more high-performance, the performance requirements for common-mode inductors are constantly increasing. High-precision winding processes are crucial for ensuring the inductance accuracy of common-mode inductors, reducing DC resistance, and improving anti-interference capabilities. However, traditional winding and wiring devices face many difficulties in achieving precision winding. The precision limitations of mechanical transmission components and the lag in the response of the control system make it difficult to accurately control the tension of the wires, the winding spacing, and the number of turns during the winding process, resulting in unstable winding quality and failing to meet the stringent requirements of high-end electronic devices for common-mode inductors.

[0003] According to the published common-mode inductor magnetic ring winding and arranging device (publication number: CN214312898U), it includes a U-shaped rotating clamping arm, a rotating drive, and a lateral drive that drives the rotating clamping arm and the rotating drive to move horizontally. A longitudinal drive that drives the rotating drive and the rotating clamping arm to move longitudinally is provided between the lateral drive and the rotating drive. In this utility model, the U-shaped rotating clamping arm can move up and down during rotation, avoiding any jamming between the wound magnetic ring and other structures such as the wire storage ring or wire. Simultaneously, it can adjust the center of the magnetic ring during the winding process, resulting in a more aesthetically pleasing and neat winding arrangement.

[0004] In the aforementioned application, during the winding process of the magnetic ring, the magnetic ring wobbles as the rotating clamping arm moves, resulting in uneven winding of the copper wire, which needs to be improved. Therefore, we propose a magnetic ring winding and wiring device for common mode inductors. Utility Model Content

[0005] This invention proposes a magnetic winding cable arrangement device for common mode inductors.

[0006] The technical solution of this utility model is as follows: A magnetic winding and wiring device for common mode inductors includes a rotating arm, a wire feeding assembly is provided at the top of the rotating arm, a wire threading assembly is provided at the bottom of the wire feeding assembly, and a uniform winding and wiring mechanism is provided on the side of the rotating arm.

[0007] The winding and arranging mechanism includes a hollow block, which is fixedly connected to the side of the rotating arm. A drive motor passes through the side of the hollow block, and a threaded rod is fixedly connected to the end of the output shaft of the drive motor. A threaded sleeve is threadedly connected to the circumferential surface of the threaded rod, and a connecting plate is fixedly connected to the circumferential surface of the threaded sleeve. A motor passes through the bottom of the connecting plate, and a rotating cylinder is fixedly connected to the end of the output shaft of the motor.

[0008] The rotating cylinder has staggered grooves on its circumferential surface, and the inner wall of the hollow block is fixedly connected to a limit rod. The staggered groove design helps to enhance the friction with the magnetic ring.

[0009] The threaded sleeve is slidably connected to the circumferential surface of the limiting rod, and the side cross-section of the hollow block is set to concave shape, which helps to enhance the driving force of the drive motor.

[0010] The uniform winding and laying mechanism is set into two groups and is symmetrical to each other along the vertical central axis at the bottom of the hollow block. This design is beneficial for effectively clamping the magnetic ring.

[0011] The hollow block is equipped with a wiping mechanism, which includes a first sprocket fixedly connected to the circumferential surface of the threaded rod. A fixing plate is fixedly connected to the side of the rotating arm, and a rotating shaft passes through the side of the fixing plate. A wiping wheel is fixedly connected to the circumferential surface of the rotating shaft. This design is beneficial for cleaning the copper wire when it comes into contact with the wiping wheel.

[0012] A second sprocket is fixedly connected to the circumferential surface of the shaft, and a chain is provided on the circumferential surface of the first sprocket. This design helps to reduce manufacturing costs.

[0013] The first sprocket meshes with the chain, and the second sprocket meshes with the chain. This design is advantageous because when the first sprocket rotates, it drives the chain to move; when the chain moves, the second sprocket rotates.

[0014] The wiping wheel is located inside the wire threading assembly and can clean the copper wire, reduce the adhesion of impurities, and prevent damage during the winding process.

[0015] The working principle and beneficial effects of this utility model are as follows:

[0016] 1. This utility model uses the driving force of a drive motor to drive the hollow block, threaded rod, threaded sleeve, motor, connecting plate, limit rod, rotating cylinder, and interlaced groove components to cooperate with each other. This enables the drive motor, which runs through the side of the hollow block, to start, thereby driving the threaded rod fixed on the output shaft to rotate. At the same time, it drives the two threaded sleeves on the circumferential surface of the limit rod to move linearly. During the winding and wiring process of the magnetic ring, this prevents the magnetic ring from shaking and avoids uneven winding of the copper wire.

[0017] 2. This utility model uses the rotational force of the threaded rod to drive the first sprocket, second sprocket, rotating shaft, wiping wheel, chain, fixing plate and other components to cooperate with each other. When the threaded rod rotates, it drives the first sprocket fixed on the circumferential surface to rotate, thereby causing the intermeshing chain to move. The movement of the chain causes the intermeshing second sprocket to be pushed, and at the same time, it causes the rotating shaft passing through the side of the fixing plate to rotate. During the winding and wiring process of the magnetic ring, impurities attached to the surface of the copper wire can be removed, avoiding the copper wire from being damaged during the winding process.

[0018] Of course, any product implementing this utility model does not necessarily need to achieve all of the advantages described above at the same time. Attached Figure Description

[0026] The technical solutions of this utility model will be clearly and completely described below with reference to the embodiments of this utility model. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of this utility model.

[0027] Example 1

[0028] like Figures 1-5 As shown, this embodiment proposes a common mode inductor magnetic winding and wiring device, including a rotating arm 1, a wire feeding assembly 2 is provided at the top of the rotating arm 1, a wire threading assembly 3 is provided at the bottom of the wire feeding assembly 2, and a uniform winding and wiring mechanism 4 is provided on the side of the rotating arm 1.

[0029] The winding and wiring mechanism 4 includes a hollow block 41, which is fixedly connected to the side of the rotating arm 1. A drive motor 42 passes through the side of the hollow block 41. A threaded rod 43 is fixedly connected to the end of the output shaft of the drive motor 42. A threaded sleeve 44 is threadedly connected to the circumferential surface of the threaded rod 43. A connecting plate 45 is fixedly connected to the circumferential surface of the threaded sleeve 44. A motor 47 passes through the bottom of the connecting plate 45. A rotating cylinder 48 is fixedly connected to the end of the output shaft of the motor 47.

[0030] The rotating cylinder 48 has interlaced grooves 49 on its circumferential surface. The inner sidewall of the hollow block 41 is fixedly connected to a limit rod 46. The design of the interlaced grooves 49 is beneficial to enhancing the friction with the magnetic ring.

[0031] The threaded sleeve 44 is slidably connected to the circumferential surface of the limiting rod 46. The side section of the hollow block 41 is set to be concave, which helps to enhance the driving force of the drive motor 42.

[0032] The uniform winding and laying mechanism 4 is set into two groups and is symmetrical to each other along the vertical central axis at the bottom of the hollow block 41. The above design is conducive to the effective clamping of the magnetic ring.

[0033] In this embodiment, when the magnetic ring needs to be wound and arranged, the operator holds the magnetic ring between two rotating cylinders 48, and then starts the drive motor 42 that passes through the side of the hollow block 41, thereby driving the threaded rod 43 fixed to the output shaft to rotate. At the same time, it drives the two threaded sleeves 44 that are threaded to the circumferential surface to move linearly on the circumferential surface of the limiting rod 46, thereby bringing them closer to each other. When the threaded sleeves 44 approach each other, they drive the connecting plate 45 fixed to the circumferential surface to move. The movement of the connecting plate 45 drives the motor 47 that passes through the bottom to move, and at the same time causes the rotating cylinder 48 fixed to the end of the output shaft to move. As the threaded sleeves 44 continue to move, the rotating cylinder 48 contacts the magnetic ring and clamps the magnetic ring, so that the magnetic ring contacts the inner wall of the interlaced groove 49. When the magnetic ring is clamped, the operator starts the motor 47 that passes through the bottom of the connecting plate 45, thereby driving the rotating cylinder 48 to rotate, and at the same time driving the magnetic ring to rotate. At this time, the operator starts the wire feeding assembly 2 set at the top of the rotating arm 1, so that the copper wire enters the inner wall of the wire threading assembly 3, thereby performing winding and arrangement.

[0034] Example 2

[0035] like Figures 1-5As shown, based on the same concept as Embodiment 1 above, this embodiment also proposes that a wiping mechanism 5 is provided inside the hollow block 41. The wiping mechanism 5 includes a first sprocket 51, which is fixedly connected to the circumferential surface of the threaded rod 43. A fixing plate 52 is fixedly connected to the side of the rotating arm 1. A rotating shaft 53 passes through the side of the fixing plate 52. A wiping wheel 54 is fixedly connected to the circumferential surface of the rotating shaft 53. The above design is beneficial to cleaning the copper wire when it comes into contact with the wiping wheel 54.

[0036] A second sprocket 56 is fixedly connected to the circumferential surface of the shaft 53, and a chain 55 is provided on the circumferential surface of the first sprocket 51. The above design helps to reduce manufacturing costs.

[0037] The first sprocket 51 meshes with the chain 55, and the second sprocket 56 meshes with the chain 55. This design is advantageous because when the first sprocket 51 rotates, it drives the chain 55 to move; when the chain 55 moves, the second sprocket 56 rotates.

[0038] The wiping wheel 54 is located inside the wire threading assembly 3. It can clean the copper wire, reduce the adhesion of impurities, and prevent damage during the winding process.

[0039] In this embodiment, when the threaded rod 43 rotates, it drives the first sprocket 51 fixed on the circumferential surface to rotate, thereby causing the intermeshing chain 55 to move. The movement of the chain 55 causes the intermeshing second sprocket 56 to be pushed, and at the same time, it causes the rotating shaft 53 passing through the side of the fixed plate 52 to rotate. The rotation of the rotating shaft 53 drives the wiping wheel 54 fixed on the circumferential surface to rotate inside the wire threading assembly 3, thereby cleaning the copper wire to be wound and removing impurities attached to the surface to prevent the copper wire from being damaged.

[0040] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model shall be included within the protection scope of the present utility model.
