Description

Technical Field

[0001] The utility model relates to the technical field of automated common-mode inductor processing, in particular to a winding machine. Background Art

[0002] A winding machine is a fully automated or semi-automated processing equipment used to wind enameled copper wire around the outside of a magnetic ring to form a common-mode inductor coil. Depending on the different functions of the common-mode inductor coil, the winding method and number of winding turns for the external copper wire are different. In the existing winding machines on the market that can realize fully automated winding operations for magnetic rings, the magnetic ring is generally rotated horizontally on the winding machine to realize the wire winding on the magnetic ring. That is, the magnetic ring clamping device drives the magnetic ring to rotate horizontally around the winding station, and the hooking device and the winding device are always fixed and do not rotate, thereby realizing the winding of the wire on the magnetic ring. In this winding method, the winding device only guides the winding of the wire and cannot provide effective preload for the winding of the wire. When processing common-mode inductor coils, the existing winding machine will have uneven coil arrangement and cross-overlapping of the wire outside the magnetic ring, so that the processed common-mode inductor cannot meet higher quality requirements.

[0035] In order to make the purpose, technical solution and advantages of the utility model more clear, the utility model is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the utility model and are not used to limit the utility model.

[0036] See also Figure 1-Figure 10 , which is a winding machine 100 provided by the utility model. The winding machine 100 provided by the utility model can automatically wind the wire onto the magnetic ring in a manner that the magnetic ring does not rotate but the wire rotates, and can complete the processing of common-mode inductors of ordinary winding methods, and is more suitable for the processing of common-mode inductors that require butterfly winding methods.

[0037] Furthermore, if Figure 1 As shown, it is a schematic diagram of the three-dimensional structure of a winding machine 100 provided by the utility model without the frame shell. The winding machine 100 is used to wind the wire onto the magnetic ring 12, so as to fully automate the processing of the common mode inductor. The winding machine 100 includes a winding platform 10, and the winding operation of the magnetic ring is completed on the winding platform 10. Therefore, at least one magnetic ring winding station 11 is provided on the winding platform 10. Figure 1 As shown, in this embodiment, two magnetic winding stations 11 symmetrically arranged side by side are provided on the winding platform 10, and each magnetic winding station 11 can complete the winding of a winding on the common-mode inductor. After completing the winding of one winding on the first magnetic winding station 11, it will be transported to the second magnetic winding station 11 to complete the winding of the second winding, thereby completing the common-mode inductor.

[0038] like Figure 2 As shown, it is a front view of the magnetic ring 12 used for the common mode inductor processed by the winding machine 100 provided by the utility model. The magnetic ring 12 is provided with two mutually perpendicular first axes 121 and second axes 122 along the center, and the magnetic ring 12 is divided into a first half ring 123 and a second half ring 124 along the first axis 121. The first axis 121 and the second axis 122 correspond to the Y axis and the X axis on the winding platform 10, respectively. Among them, the magnetic ring 12 is divided into a first half ring 123 and a second half ring 124 by the first axis 121. During the processing, the first half ring 123 is wound first, and then the second half ring 124 is wound. At the same time, when the butterfly winding method is performed, when the first half ring 123 is wound, the first half 1231 of the first half ring 123 is wound first, and then the magnetic ring 12 is turned over, and the direction is reversed to wind the second half 1232 of the first half ring 123.

[0039] Furthermore, if Figure 1 and Figure 3 As shown, the winding machine 100 provided by the utility model includes a loading and unloading device 20 for conveying a magnetic ring 12 arranged on a winding platform 10, and a wire feeding device 30, a magnetic ring clamping device 40, a winding device 50 and a wire hooking device 60 arranged around a magnetic ring winding station 11. The winding of the two windings on the above-mentioned magnetic ring 12 is achieved through the mutual coordination and control between the loading and unloading device 20, the wire feeding device 30, the magnetic ring clamping device 40, the winding device 50 and the wire hooking device 60. In addition, in order to more reasonably arrange the space arrangement on the winding platform 10, the two magnetic ring winding stations 11 on the winding platform 10 are arranged side by side along the second axis 122 of the magnetic ring 12. At the same time, the loading and unloading device 20 on the winding machine 100 is as shown in FIG. Figure 1As shown, it also spans the entire winding platform 10 along the setting direction of the second axis 122. The winding platform 10 is arranged in sequence in the direction of the second axis 122: a loading station, a first magnetic ring winding station 11, a second magnetic ring winding station 11 and a unloading station, and the loading and unloading device 20 sequentially realizes the transportation of the magnetic ring 12 on two adjacent stations. A wire feeding device 30, a magnetic ring clamping device 40, a winding device 50 and a wire hooking device 60 are arranged on the same magnetic ring winding station 11. Among them, the wire hooking device 60 is located below the winding platform 10, and moves to the top of the magnetic ring 12 by lifting during the winding process to hook the wire to the bottom of the magnetic ring 12. Above the winding platform 10 of the winding machine 100, the magnetic ring clamping device 40 and the winding device 50 are relatively arranged along the first axis 121 of the magnetic ring 12 and move horizontally. During the winding process, the magnetic ring clamping device 40 is located at the rear side of the magnetic ring 12, and the winding device 50 is located at the front side of the magnetic ring 12. The magnetic ring clamping device 40 clamps the half of the magnetic ring 12 divided along the first axis, and the winding device 50 is used to wind the other half of the magnetic ring 12 that is not clamped. In order to better save the space of the winding platform 10, the wire feeding devices 30 set on the two magnetic ring winding stations 11 are arranged along the second axis 122 of the magnetic ring 12, and are respectively located on the left and right sides of the winding platform 10, and extend along the second axis 122 of the magnetic ring 12 to the magnetic ring winding station 11 during the wire feeding process. After completing the wire feeding, the wire feeding device 30 returns to the initial position along the second axis 122. The wire feeding device 30 and the loading and unloading device 20 are arranged on the winding platform 10 in parallel along the second axis 122 , and the wire feeding device 30 is located at the front side of the winding platform 10 .

[0040] Furthermore, if Figure 3 As shown, the wire feeding device 30 provided by the utility model includes a second translation component 31 for conveying the front end of the wire to the magnetic winding station 11 and a tangent component 32 for cutting off the end of the wire. The setting direction of the second translation component 31 is consistent with the direction of the second axis 122 of the magnetic ring 12. When the wire needs to be input, the second translation component 31 drives the wire to move to the magnetic winding station 11. After the wire is hooked by the hook device 60, the second translation component 31 drives the wire back to the initial position. And after the wire is input, the end of the wire is cut off by the tangent component 32. The structure of the tangent component 32 in the wire feeding device 30 provided by the utility model can adopt a tangent component in an automatic tangent device provided in the publication number CN209962877U, which is used to cut off the end of the wire.

[0041] like Figure 3As shown, it is an enlarged view of the local three-dimensional structure of a magnetic ring winding station 11 in the winding machine 100 provided by the utility model. The magnetic ring clamping device 40 in the winding machine 100 provided by the utility model includes a pair of magnetic ring clamps 41 for fixing the magnetic ring 12, a first translation component 42 for moving the magnetic ring 12 to the magnetic ring winding station 11, and a first flip component 43 for driving the pair of magnetic ring clamps 41 to flip horizontally. The magnetic ring clamping device 40 provided by the utility model is used to clamp and fix the magnetic ring 12 transported by the loading and unloading device 20 during the winding process using a pair of magnetic ring clamps 41. The first translation component 42 is used to move the magnetic ring 12 clamped by the pair of magnetic ring clamps 41 to the magnetic ring winding station 11, keep the horizontal setting of the magnetic ring 12, and complete the winding of the wire of the front half 1231 of the half ring 123 of the magnetic ring 12 that is not clamped. At the same time, after winding a coil of a winding, the magnetic ring 12 clamped by a pair of magnetic ring clamps 41 is horizontally flipped 180° by the first flip assembly 43, and then the wire of the rear half 1232 of the half ring 12 not clamped is wound.

[0042] Specifically, Figure 4 , which is a schematic diagram of the three-dimensional structure of the magnetic ring clamping device 40 provided by the utility model. Among them, a pair of magnetic ring clamps 41 of the magnetic ring clamping device 40 includes a first clamping rod 411 and a second clamping rod 412 arranged parallel to each other and a clamping drive assembly 413 driving the first clamping rod 411 and the second clamping rod 412. The first clamping rod 411 and the second clamping rod 412 are arranged in parallel along the direction of the first axis 121 of the magnetic ring 12.

[0043] By driving the clamping drive assembly 413 at the same time, the first clamping rod 411 and the second clamping rod 412 move backward to achieve clamping of the magnetic ring 12 on the first axis 121. When the first clamping rod 411 moves toward the rear of the winding platform 10 and the second clamping rod 412 moves toward the front of the winding platform 10, the first clamping rod 411 and the second clamping rod 412 clamp the magnetic ring 12 from both ends of the first axis 121 of the magnetic ring 12. When the first clamping rod 411 moves toward the front of the winding platform 10 and the second clamping rod 412 moves toward the rear of the winding platform 10, the space between the first clamping rod 411 and the second clamping rod 412 gradually increases, and the magnetic ring is released.

[0044] like Figure 4As shown, when a pair of magnetic ring clamps 41 clamp the two ends of the first axis 121 of the magnetic ring 12, the space enclosed by the first clamping rod 411 and the second clamping rod 412 surrounds the second half ring 124 of the magnetic ring 12, so that the second half ring 124 of the magnetic ring 12 cannot be wound. At the same time, the first half ring 123 of the magnetic ring 12 is arranged on a side away from the first clamping rod 411 and the second clamping rod 412, so that the first half ring 123 can realize the winding and hooking operations with the winding device 50 and the hooking device 60.

[0045] Furthermore, if Figure 4 As shown, the magnetic ring clamping device 40 provided by the utility model also includes a magnetic ring blocking assembly 44. The magnetic ring blocking device 44 is used to limit the coil winding range when two different coils are wound on the same half ring of the magnetic ring 12, and further improve the tightness and consistency of the coil winding. The magnetic ring blocking assembly 44 includes a first driving member 441 fixed to the first translation assembly 42 and a stopper 442 driven by the first driving member 441 to extend along the first axis 121 to the first half ring 123 of the magnetic ring 12, and the stopper 442 is provided with an arc-shaped abutting surface 4421 that fits the first half ring 123 of the magnetic ring 12. In this embodiment, when the first half ring 123 of the magnetic ring 12 is winding, the first driving member 441 of the magnetic ring blocking assembly 44 drives the stopper 442 to move toward the first half ring 123 of the magnetic ring 12, and makes the arc-shaped abutting surface 4421 abut against the rear half 1232 of the first half ring 123, so that when winding, only the front half 1231 of the first half ring 123 of the magnetic ring 12 cooperates with the wire hooking device 60 and the winding device 50, and the wire is wound at the front half 1231 of the first half ring 123 to form the first coil of the first winding. The magnetic ring blocking device 44 provided by the utility model can effectively control the winding area when the first half of the first half ring 123 or the second half ring 124 of the magnetic ring 12 is wound, ensuring that the position of the coil arrangement is accurate and the arrangement is uniform.

[0046] Specifically, Figure 4As shown, the first flip assembly 43 of the magnetic ring clamping device 40 includes a vertical fixed plate 431 fixed on the first translation assembly 42, a vertical rotating plate 432 fixedly connected to a pair of magnetic ring clamps 41, a transmission assembly 433 for driving the vertical rotating plate 432 to flip horizontally relative to the vertical fixed plate 431, and a positioning assembly 434 for limiting the horizontal flipping of the vertical rotating plate 432 relative to the vertical fixed plate 431. In this embodiment, the transmission assembly 433 includes a horizontally arranged cylinder arranged on the vertical fixed plate 431, a rack is arranged on the driving shaft of the cylinder, and also includes a rotating shaft arranged on the vertical rotating plate 432 and a gear sleeved on the rotating shaft. Through the mutual cooperation of the rack and the gear, the horizontal flipping of the vertical rotating plate 432 relative to the vertical fixed plate 431 is realized, thereby driving the pair of magnetic ring clamps 41 fixed on the vertical rotating plate 432 to flip horizontally, and realizing the horizontal 180° flipping of the clamped magnetic ring 12.

[0047] At the same time, in order to ensure that the magnetic ring 12 can always maintain a horizontal and stable state during the winding process and avoid unnecessary flipping of the pair of magnetic ring clamps 41, the magnetic ring clamping device 40 also has a free positioning component 434. Figure 4 As shown, the positioning assembly 434 includes a cylinder 4343 fixed on the vertical fixed plate 431, a positioning column 4342 driven by the cylinder 4343, and a positioning hole 4341 provided on the vertical rotating plate 432. When the magnetic ring 12 is in the winding state, the cylinder 4343 drives the positioning column 4342 to be inserted into the positioning hole 4341, so that the vertical rotating plate 432 and the vertical fixed plate 431 are fixed to each other. When the magnetic ring 12 needs to be flipped 180°, the cylinder 4343 drives the positioning column 4342 to move out of the positioning hole 4341, and at the same time, the transmission assembly 433 drives the vertical rotating plate 432 to flip horizontally 180°.

[0048] like Figure 3 As shown, the winding device 50 in the winding machine 100 provided by the utility model includes a pair of clamping blocks 51 for clamping wires, a second flipping assembly 52 for driving the pair of clamping blocks 51 to flip, and a second rotating assembly 53 for driving the pair of clamping blocks 51 to rotate horizontally. The pair of clamping blocks 51 in the winding device 50 are used to clamp the wires from the bottom of the magnetic ring 12, and pull the wires from the outside of the magnetic ring 12 to the top of the magnetic ring 12. The pair of clamping blocks 51 are flipped in the horizontal direction by the second flipping assembly 52, and the pair of clamping blocks 51 are rotated in the horizontal direction by the second rotating assembly 53, so as to realize a winding method in which the magnetic ring 12 is stationary and the wires are wound in rotation.

[0049] Specifically, Figure 5As shown, it is a partial exploded view of a pair of wire clamping blocks 51 in the winding machine 100 provided by the utility model. The pair of wire clamping blocks 51 provided by the utility model include a first wire clamping rod 511 and a second wire clamping rod 512 sleeved in the first wire clamping rod 511, and the first wire clamping rod 511 and the second wire clamping rod 512 are arranged along the first axis 121 of the magnetic ring 12, and the two are coaxially arranged. The first wire clamping rod 511 is provided with a through hole 5111 along its length direction, and a wire clamping fixing block 5112 is provided at the end of the first wire clamping rod 511. The length direction of the first wire clamping rod 511 is the direction of the first axis 121 of the magnetic ring 12. One end of the second wire clamping rod 512 is inserted into the through hole 5111 and is movably connected to the first wire clamping rod 511 through a linkage shaft 5122. The second clamping rod 512 is inserted into the through hole 5111 of the first clamping rod 511, and is fixed in the first clamping rod 511 through the linkage shaft 5122, and moves in the direction of the through hole set on the first clamping rod 511. The end of the second clamping rod 512 extending out of the first clamping rod 511 is provided with a clamping movable block 5121, and a gap is formed between the clamping movable block 5121 and the clamping fixed block 5112. When the second clamping rod 512 retracts into the first clamping rod 511, the gap between the clamping fixed block 5112 and the clamping movable block 5121 is reduced to clamp the wire.

[0050] The pair of clamping blocks 51 of the winding device 50 further include a clamping seat 513, and a second driving assembly 514 disposed on the clamping seat 513 to drive the first clamping rod 511 and the second clamping rod 512 to extend and retract relative to each other. The first clamping rod 511 is fixed to the clamping seat 513, and the second clamping rod 512 is movably connected to the second driving assembly 514. Figure 5 As shown, the second driving assembly 514 includes a lifting cylinder 5141, a lifting block 5142 driven by the lifting cylinder 5141, and a sliding track 5143 arranged on the side of the lifting block 5142. Both ends of the linkage shaft 5122 on the second clamping rod 512 are embedded in the sliding track 5143, so that the lifting cylinder 5141 of the second driving assembly 514 can drive the second clamping rod 512 to extend and retract relative to the first clamping rod 511 during the lifting and lowering process of the lifting block 5142.

[0051] Furthermore, the winding device 50 provided by the utility model also includes a fine-tuning component 515 disposed on the clamping seat 513, and the function of the fine-tuning component 515 is to manually adjust the gap between the clamping movable block 5121 and the clamping fixed block 5112, so as to be applicable to the loosening and tightening operation of a pair of clamping blocks 51 when clamping the wire due to the difference in size of the same wire. The fine-tuning component 515 includes a fixing member 5151 fixed on the clamping seat 513, a movable member 5152 fixed on the lifting block 5142, and an adjusting rod 5153 disposed on the fixing member 5151 and abutting against the movable member 5152, and the adjusting rod 5153 limits the gap between the clamping movable block 5121 and the clamping fixed block 5112 by adjusting the spacing between the fixing member 5151 and the movable member 5152.

[0052] like Figure 3 As shown, the winding device 50 provided by the utility model also includes a third translation assembly 55 fixed on the second rotating assembly 53. The third translation assembly 55 is fixed on the second rotating assembly 53, so that the third translation assembly 55 can set the second rotating assembly 53 to rotate synchronously in the horizontal direction. A pair of clamping blocks 51 of the winding device 50 are fixed on the third translation assembly 55, so that the pair of clamping blocks 51 can be translated in the horizontal direction along with the third translation assembly 55. The third translation assembly 55 is arranged on the winding platform 10 along the direction of the first axis 121 of the magnetic ring 12. When the magnetic ring 12 is in the wire feeding operation, it is ensured that the hook device 60 can move upward smoothly to hook the wire. In order to avoid the hook device 60, the pair of clamping blocks 51 are moved from the magnetic ring winding station 11 to the front side of the winding platform 10 along the direction of the first axis 121 through the third translation assembly 55. When the winding device 50 is required to perform winding operation, the winding device 50 is moved along the first axis 121 to the magnetic winding station 11 through the third translation assembly 55 .

[0053] Furthermore, if Figure 3 and Figure 8 As shown, the winding device 50 provided by the utility model also includes a wire blocking assembly 54 fixed on the third translation assembly 55, and the wire blocking assembly 54 rotates and moves horizontally synchronously with the pair of wire clamping blocks 51. The wire blocking assembly 54 is used to cooperate with the pair of wire clamping blocks 51 to control the active area of ​​the wire under the magnetic ring 12, thereby ensuring that the pair of wire clamping blocks 51 can smoothly grab the wire when flipping from the bottom of the magnetic ring 12 to the top of the magnetic ring 12. At the same time, it can also effectively protect the wire and prevent the wire from colliding with other devices on the winding machine 100 during the winding process and scratching the surface coating of the wire.

[0054] Specifically, Figure 8As shown, it is a three-dimensional structural schematic diagram of the wire blocking assembly 54 in the winding device 50 provided by the utility model. The wire blocking assembly 54 includes a wire blocking seat 541 with an opening 5411, a first wire blocking block 542 and a second wire blocking block 543 that block the opening respectively, and a third driving member 544 that drives the first wire blocking block 542 and a fourth driving member 545 that drives the second wire blocking block 543. The wire blocking seat 541 encloses a rectangular space at the winding platform 10 for the active area when the wire is wound, and the wire blocking seat 541 is provided with an opening 5411 that runs through from top to bottom, and the opening 5411 can simultaneously allow the hook needle 61 in the hooking device 60 to pass through. During the winding process, the wire blocking block of the wire blocking assembly 53 and a pair of clamping blocks 51 appear relative to each other to control the active area of ​​the wire. Specifically, when a pair of wire clamping blocks 51 are performing a wire winding operation at the front half 1231 of the first half ring 123 of the magnetic ring 12, the third driving member 544 of the wire blocking assembly 54 located below the magnetic ring 12 drives the first wire blocking block 542 to extend forward to block the left area of ​​the opening 5411. At the same time, the fourth driving member 545 drives the second wire clamping block 543 back to its initial position, opening the right area of ​​the opening 5411, so that the wire can move in the right area of ​​the opening 5411 during the winding process, and at this time, the pair of wire clamping blocks 51 are clamping and winding the wire in the right area below the magnetic ring 12. Similarly, when a pair of wire clamping blocks 51 are performing a wire winding operation at the rear half 1232 of the first half ring 123 of the magnetic ring 12, the magnetic ring 12 has been flipped 180°, and the pair of wire clamping blocks 51 are clamping and winding the wire in the left area below the magnetic ring 12. At this time, the fourth driving member 545 of the wire blocking assembly 54 located below the magnetic ring 12 drives the second wire blocking block 543 to extend forward to block the right area of ​​the opening 5411. At the same time, the third driving member 544 drives the first wire clamping block 542 back to its initial position, opening the left area of ​​the opening 5411, so that the wire can move in the left area of ​​the opening 5411 during the winding process.

[0055] Furthermore, if Figure 3 and Fig. 9 As shown, the hooking device 60 provided by the utility model includes a hook needle 61, a first rotating assembly 62 that drives the hook needle 61 to rotate horizontally, and a first driving assembly 63 that drives the hook needle 61 to hook the wire. The hook needle 61 is used to pass through the center of the magnetic ring 12, and hook the wire from the top of the magnetic ring 12 through the center hole of the magnetic ring 12 to the bottom of the magnetic ring 12. Among them, the first rotating assembly 62 is used to drive the hook needle 61 to rotate horizontally, so that the hook needle 61 can rotate horizontally synchronously with a pair of clamping blocks 51 of the winding device 50, so as to realize the winding method in which the magnetic ring 12 is stationary and the wire is rotated and wound. The first driving assembly 63 is used to drive the hook needle 61 to rise and fall in the vertical direction and translate in the horizontal direction.

[0056] Specifically, Fig. 9As shown, the first driving assembly 63 of the hooking device 60 includes a vertical lifting assembly 631 and a fourth translation assembly 632 driven by the vertical lifting assembly 631, and the first rotating assembly 62 is fixed to the fourth translation assembly 632. The vertical lifting assembly 631 is used to drive the hook needle 61 to rise and fall in the vertical direction to hook the wire. The fourth translation assembly 632 is used to adjust the hook portion at the top of the hook needle 61 to always remain on the same vertical axis with the center of the magnetic ring 12 after the hook needle 61 rotates. Because the hook portion at the top of the hook needle 61 is not coaxially arranged with the central axis of the hook needle 61, the first driving assembly 63 needs to solve the problem of the central axis of the top hook portion deviating from the central axis of the magnetic ring 12 due to the horizontal rotation of the hook needle 61 by setting the fourth translation assembly 632.

[0057] Furthermore, if Fig. 9 As shown, the hooking device 60 provided by the utility model also includes a mounting seat 64 arranged on the first rotating assembly 62, a movable seat 65 that can be lifted and lowered relative to the mounting seat 64, and a detection assembly 66 for detecting the movement of the movable seat 65 relative to the mounting seat 64. The mounting seat 64 is fixedly connected to the first rotating assembly 62, and the movable seat 65 is movably connected to the mounting seat 64 in the vertical direction, so that the mounting seat 64 and the movable seat 65 can rotate horizontally with the first rotating assembly 62. The hook 61 is fixed to the top of the movable seat 65 to realize the horizontal rotation of the hook 61, and the hook 61 can also move relative to the mounting seat 64 in the vertical direction. When the top hook of the hook 61 hooks the wire, the wire will provide an upward pulling force to the hook 61, so that the hook 61 drives the movable seat 65 to move vertically upward relative to the mounting seat 64. At this time, the detection assembly 66 can effectively detect whether the hook 61 hooks the wire. The detection component 66 includes a sensor 662 fixed on the mounting base 64 and a sensor sheet 661 fixed on the movable base 65. The sensor sheet 661 can move relative to the sensor 662 as the movable base 65 rises and falls. At the same time, the sensor sheet 661 will not cause the movable base 64 to rotate in the horizontal direction. Therefore, when the hook 61 hooks the wire and drives the movable base 64 to move upward, the sensor 662 can obtain a signal through the movement of the sensor sheet 661 to determine that the hook 61 hooks the wire.

[0058] The first translation assembly 42, the second translation assembly 31, the third translation assembly 55, the fourth translation assembly 632, the first drive assembly 63 and the vertical lifting assembly 631 in the winding machine 100 provided by the utility model can all use a motor screw structure or a cylinder slide rail structure to realize the horizontal translation function. The first flip assembly 43, the transmission assembly 433, the second flip assembly 52, the second rotation assembly 53, and the first rotation assembly 62 in the winding machine 100 provided by the utility model can all use a rotating motor with a reducer, or a cylinder drives a gear rack to drive a rotating shaft to realize the rotation function. The first drive member 441, the second drive member 514, the third drive member 544 and the fourth drive member 545 in the winding machine 100 provided by the utility model can be components that realize the driving function by means of cylinders, motors, etc.

[0059] The magnetic ring clamping device 40 of the winding machine 100 provided by the utility model is used to fix the magnetic ring 12, and the winding device 50 and the wire hooking device 60 can rotate relative to the magnetic ring 12, and then the winding of the wire outside the magnetic ring 12 is completed to form a coil under the mutual cooperation of the winding device 50 and the wire hooking device 60. The magnetic ring 12 is fixed, and the wire is rotated and wound, and the phenomenon of wire crossing or overlapping when the wire is wound on the magnetic ring 12 is reduced. The uniformity and consistency of the arrangement of the coil outside the magnetic ring 12 can be effectively controlled, and the product quality of common mode inductor processing can also be improved.
