Description

Technical Field

[0001] The utility model relates to the technical field of winding machines, in particular to a magnetic ring clamping device and a winding machine with the magnetic ring clamping device. 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 function of the common-mode inductor coil, the winding method and number of turns of the external copper wire are different. In existing winding machines, a magnetic ring is generally rotated horizontally on the winding machine to achieve wire winding on the magnetic ring. In this winding method, the winding device only guides the winding of the wire and cannot provide effective pre-tightening force for the winding of the wire. Therefore, when processing common-mode inductor coils, this type of winding machine will have loose coil arrangement and cross-overlapping of wires, making it impossible for the processed common-mode inductor to meet higher quality requirements.

[0003] If the existing winding machine is changed to a method where the magnetic ring is fixed and the winding is achieved by horizontal rotation of the winding device, the preload force during the winding of the wire can be controlled. When the magnetic ring clamping device in the existing winding machine is matched with the rotatable winding device, the internal layout space of the winding machine can only be greatly increased to meet the layout of the horizontally rotatable winding device. Otherwise, the winding device will interfere with the magnetic ring clamping device during the horizontal rotation process and the winding operation of the magnetic ring cannot be completed.

[0031] 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.

[0032] See also Figure 1-Figure 7 , is a magnetic ring clamping device 100 provided by the utility model. The magnetic ring clamping device 100 is arranged on a winding machine and is used to fix the magnetic ring 10. In this embodiment, as Figure 5-6As shown, the magnetic ring 10 is provided with two mutually perpendicular first axes 11 and second axes 12 along its center. That is, in the horizontal direction, there are two mutually perpendicular first directions (Y-axis) and second directions (X-axis), wherein the first direction (Y-axis) is parallel to the first axis 11 of the magnetic ring 10, and the second direction (X-axis) is parallel to the second axis 12 of the magnetic ring 10. The first axis 11 and the second axis 12 both pass through the center of the magnetic ring 10. In this embodiment, the magnetic ring 10 is a circular ring structure. The magnetic ring clamping device 100 provided by the utility model is also suitable for use with runway-type magnetic rings and elliptical magnetic rings. As Figure 5 As shown, the magnetic ring 10 is divided into a first half ring 13 and a second half ring 14 along the first axis 11. Each magnetic ring clamping device 100 is used to fix the magnetic ring 10 and realize the winding operation of the first half ring 13 or the second half ring 14 of the magnetic ring 10 in the winding machine, that is, the magnetic ring 10 fixed by each magnetic ring clamping device 100 can only complete the winding operation of half area of ​​its own structure.

[0033] Furthermore, if Figure 2 As shown, the magnetic ring clamping device 100 provided by the utility model includes a vertical flip platform 20 and a magnetic ring clamping assembly 30 fixed on the vertical flip platform 20. Among them, the magnetic ring clamping assembly 30 is used to clamp the magnetic ring 10 and fix the magnetic ring 10 to ensure that during the winding operation, the magnetic ring 10 is always in the center of the winding station and will not deviate, flip or rotate. In this embodiment, the magnetic ring clamping assembly 30 is fixed on the vertical flip platform 20, so that the entire magnetic ring clamping assembly 30 can be flipped horizontally along the vertical flip platform 20. Specifically, the vertical flip platform 20 drives the magnetic ring clamping assembly 30 to flip horizontally along the first axis 11 of the magnetic ring 10. That is, the vertical flip platform 20 can drive the magnetic ring clamping assembly 30 and the magnetic ring 10 clamped by it to flip horizontally along the first axis 11 passing through the center point of the magnetic ring 10, that is, flip along the first direction (Y axis) of the horizontal plane. The vertical flip platform 20 is suitable for use when the magnetic ring 10 needs to be wound by butterfly method. In the initial state, such as Figure 2 As shown, the magnetic ring clamping assembly 30 is used to fix the magnetic ring 10 and cooperate with the winding device of the winding machine to complete the winding operation on at least half of the first half ring 13 of the magnetic ring 10. Then, the magnetic ring 10 is horizontally flipped along the first axis 11 by the vertical flip platform 20. At this time, the flipped magnetic ring clamping device 100 is as shown in FIG. Figure 3 As shown, the magnetic ring clamping assembly 30 cooperates with the winding device of the winding machine to complete the winding of the other half of the unwound area of ​​the first half ring 13 of the magnetic ring 10, thereby completing the winding operation on half of the area of ​​the magnetic ring 10.

[0034] Furthermore, if Figure 5-6As shown, the magnetic ring clamping assembly 30 provided by the utility model includes a first driving assembly 31, and a first clamping rod 32 and a second clamping rod 33 arranged parallel to the first axis 11. The first driving assembly 31 is fixed on the vertical flip platform 20. In the magnetic ring clamping state, the magnetic ring clamping assembly 30 is always in a horizontal state, that is, Figure 2 The initial state shown, or Figure 3 The first driving assembly 31 simultaneously drives the first clamping rod 32 and the second clamping rod 33 connected thereto, so that the first clamping rod 32 and the second clamping rod 33 can clamp the magnetic ring 10 at both ends of the first axis 11 of the magnetic ring 10 (such as Figure 6 In a conventional winding machine, a pair of magnetic ring clamps of the magnetic ring clamping device clamp the left and right ends of the magnetic ring 10 (i.e., the two ends of the second axis 12) respectively. Therefore, when the magnetic ring clamping device is stationary, the winding device will interfere with the magnetic ring clamping devices on the left and right sides of the magnetic ring 10 during the horizontal rotation winding process, thereby failing to complete the winding operation of the magnetic ring located outside the magnetic ring clamping device.

[0035] In this embodiment, if Figure 5 and Figure 6 As shown, in the magnetic ring clamping device 100 provided by the present invention, the first clamping rod 32 and the second clamping rod 33 move in opposite directions under the drive of the first driving assembly 31 to clamp the magnetic ring 10 at both ends of the first axis 11. Figure 5 In the state, the first clamping rod 32 and the second clamping rod 33 are respectively located at the two ends of the first axis 11 of the magnetic ring 10 (i.e., the front and rear ends of the magnetic ring 10), wherein the first clamping rod 32 is driven by the first driving assembly 31 to move toward the rear side, and at the same time, the second clamping rod 33 is driven by the first driving assembly 31 to move toward the front side. The first clamping rod 32 and the second clamping rod 33 move synchronously in opposite directions, thereby approaching the magnetic ring 10 from the front and rear ends of the magnetic ring 10 to achieve clamping of the front and rear ends of the magnetic ring 10.

[0036] like Figure 6 The figure is a top view of the magnetic ring 10 clamped by the magnetic ring clamping device 100 provided by the utility model. When the magnetic ring clamping assembly 30 clamps the magnetic ring 10, the first half ring 13 of the magnetic ring 10 is located at a side away from the magnetic ring clamping assembly 30. The magnetic ring 10 is divided into a second half ring 12 located on the left side and a first half ring 11 located on the right side along the first axis 11. In the clamping state of the magnetic ring, the first half ring 13 of the magnetic ring 10 is located at a side away from the magnetic ring clamping assembly 30, that is, the first half ring 13 of the magnetic ring 10 is located on the outside of the magnetic ring clamping assembly 30, and can cooperate with the winding device of the winding machine to realize the winding operation.

[0037] Furthermore, if Figure 4As shown, in the magnetic ring clamping assembly 30 provided by the utility model, the first clamping rod 32 includes a first rod body 321 and a clamping end 322 of the first clamping rod 32 fixed to the end of the first rod body 321. The second clamping rod 33 includes a second rod body 331 and a clamping end 332 of the second clamping rod 33 fixed to the end of the second rod body 331. The first rod body 321 and the second rod body 331 are both arranged parallel to the first axis 11 of the magnetic ring 10, and the first rod body 321 and the second rod body 331 are both located on one side of the first axis 11. In this embodiment, the distance between the first rod body 321 and the first axis 11 is greater than the distance between the second rod body 331 and the first axis 11, and the length of the first rod body 321 is greater than the length of the second rod body 331.

[0038] like Figure 5 As shown, the clamping end 322 of the first clamping rod 32 and the clamping end 332 of the second clamping rod 33 are located on the first axis 11 of the magnetic ring 10 and are arranged opposite to each other. In this embodiment, the clamping end 322 of the first clamping end 32 is located at the front side of the magnetic ring 10, and the clamping end 332 of the second clamping end 33 is located at the rear side of the magnetic ring 10. The first clamping rod 32 and the second clamping rod 33 clamp and fix the magnetic ring 10 from the front and rear sides of the magnetic ring 10 respectively. Among them, the first clamping rod 32 and the second clamping rod 33 form an enclosed space 30A outside the magnetic ring 10. When the magnetic ring clamping assembly 30 clamps the magnetic ring 10, the first half ring 13 of the magnetic ring 10 is located outside the space 30A enclosed by the first clamping rod 32 and the second clamping rod 33, so that the first half ring 13 can cooperate with the winding device of the winding machine to complete the winding operation of the first half ring 13. The second half ring 14 of the magnetic ring 10 is located in a space 30A surrounded by the first clamping rod 32 and the second clamping rod 33 . The second half ring 14 in the space 30A cannot perform a winding operation.

[0039] Furthermore, if Figure 5 As shown, the clamping end 322 of the first clamping rod 32 and the clamping end 332 of the second clamping rod 33 are both L-shaped structures 3221 (3321), and clamping plates 3222 (3322) are also provided on the upper and lower side surfaces of the end of the clamping end 322 (332), and a groove for accommodating one end of the magnetic ring 10 (in this embodiment, the front end of the magnetic ring 10) is formed between the upper and lower clamping plates 3222 of the clamping end 322 of the first clamping rod 32, and one end of the magnetic ring 10 is embedded in the groove, and a groove is also formed between the upper and lower clamping plates 3322 of the clamping end 332 of the second clamping rod 33 for accommodating the other end of the magnetic ring 10 (in this embodiment, the rear end of the magnetic ring 10).

[0040] like Figure 4As shown, it is a schematic diagram of the three-dimensional exploded structure of the magnetic ring assembly 30 provided by the utility model. The first driving assembly 31 in the magnetic ring assembly 30 provided by the utility model includes a first driving member 311, a lifting block 312 arranged between the first clamping rod 32 and the second clamping rod 33 and driven by the first driving member 311, and a transmission assembly 313 that transmission-connects the lifting block 312 to the first clamping rod 32 and the second clamping rod 33 respectively. The first driving member 311 is fixed to the vertical mounting plate, and a vertical guide rail is arranged on the vertical mounting plate. The lifting block 312 is lifted and lowered in the vertical direction along the vertical guide rail under the drive of the first driving member 311. Through the lifting and lowering of the lifting block 312, the transmission assembly 313 is used to drive the first clamping rod 32 and the second clamping rod 33 to move in opposite directions in the horizontal direction.

[0041] Specifically, Figure 4 As shown, the lifting block 312 is in a V-shaped structure, and a first sliding track 3121 and a second sliding track 3122 arranged in a V-shape are arranged on the lifting block 312. The distance between the first sliding track 3121 and the second sliding track 3122 is gradually reduced from top to bottom, and the first sliding track 3121 is located at the front side of the second sliding track 3122. The transmission assembly 313 includes a first transmission rod 3131 fixed on the first clamping rod 32 and extending into the first sliding track 3121, and a second transmission rod 3132 fixed on the second clamping rod 33 and extending into the second sliding track 3122. When the lifting block 312 moves downward, the first transmission rod 3131 drives the first clamping rod 32 to move horizontally backward in the first sliding track 3121 along the setting direction of the first sliding track 3121, and at the same time, the second transmission rod 3132 drives the second clamping rod 33 to move horizontally forward in the second sliding track 3122 along the setting direction of the second sliding track 3122, so that the first clamping rod 32 and the second clamping rod 33 move in opposite directions to clamp the magnetic ring 10 (such as Figure 6 As the lifting block 312 moves upward, the first clamping rod 32 moves forward horizontally, and at the same time, the second clamping rod 33 moves backward horizontally, so that the magnetic ring 10 is released when the first clamping rod 32 and the second clamping rod 33 move in opposite directions (as shown). Figure 5 shown).

[0042] Specifically, Figure 4As shown, in order to ensure the stability of the first clamping rod 32 and the second clamping rod 33 when they move in opposite directions, the clamping magnetic ring assembly 30 also includes a first guide rail 34 and a second guide rail 35 arranged in parallel with each other, the first clamping rod 32 is arranged on the first guide rail 34, the second clamping rod 33 is arranged on the second guide rail 35, and the first driving member 311 drives the first clamping rod 32 on the first guide rail 34 and the second clamping rod 33 on the second guide rail 35 to move in opposite directions. The first guide rail 34 and the second guide rail 35 are both arranged parallel to the first axis 11 of the magnetic ring 10, and the first guide rail 34 and the second guide rail 35 are both located on the same side of the first axis 11. In this embodiment, the first guide rail 34 and the second guide rail 35 are both located on the left side of the first axis 11, so that the first half ring 13 located on the right side of the magnetic ring 10 is located on the side away from the clamping magnetic ring assembly 30, that is, the first half ring 13 is located outside the space 30A enclosed by the first clamping rod 32 and the second clamping rod 33.

[0043] Furthermore, if Figure 1-3 As shown, the magnetic ring clamping device 100 provided by the utility model also includes a magnetic shielding ring assembly 40 fixed on the vertical flip platform 20. The magnetic shielding ring assembly 40 is used in the winding operation process and is attached to the outer side of the first half ring 13 of the magnetic ring 10 to limit the winding area of ​​the magnetic ring 10 during a single winding process. Therefore, the magnetic shielding ring assembly 40 is suitable for use in common mode inductor processing using the butterfly winding method. That is, when the magnetic ring 10 is clamped on the magnetic ring clamping assembly 30, before winding, the magnetic shielding ring assembly 40 extends to block a portion of the first half ring 13 of the magnetic ring 10 to ensure that the area will not be entangled by the wire. Generally speaking, the magnetic shielding ring assembly 40 blocks half of the area of ​​the first half ring 13, that is, one quarter of the area of ​​the magnetic ring 10.

[0044] Specifically, Figure 1 and Figure 2 As shown, the magnetic shielding ring assembly 40 and the magnetic clamping ring assembly 30 are arranged side by side, and the magnetic shielding ring assembly 40 is located on the side of the first half ring 13 close to the magnetic ring 10, thereby ensuring that the magnetic shielding ring assembly 40 will not interfere with the magnetic clamping ring assembly 30, and the magnetic shielding ring assembly 40 can be effectively fitted to the winding area of ​​the magnetic ring 10, thereby preventing part of the magnetic ring 10 from being entangled by the coil during the winding process.

[0045] Furthermore, if Figure 1 As shown, the magnetic ring assembly 40 includes a second driving member 41 fixed on the vertical flip platform 20 and a stopper 42 that can be driven by the second driving member 41 to extend along the first axis 11 to the first half ring 13 of the magnetic ring 10, and the stopper 42 is provided with an arc-shaped abutting surface 43 that fits with the first half ring 13 of the magnetic ring 10. The arc-shaped abutting surface 43 can be adjusted according to the size of different magnetic rings 10, and the contact area with the magnetic ring 10 can be adjusted according to the winding requirements of different magnetic rings 10. Figure 2 As shown, when the magnetic ring 10 needs to be wound, the stopper 42 is driven by the second driving member 41 to extend toward the magnetic ring 10, and the arcuate contact surface 43 of the stopper 42 is attached to the outer side of the second half ring 13 of the magnetic ring 10. When the arcuate contact surface 43 of the stopper 42 is attached to the first half ring 13 of the magnetic ring 10, the winding operation cannot be performed in this area during the winding operation, so as to limit the winding area of ​​the winding device on the magnetic ring 10.

[0046] Furthermore, if Figure 1 As shown, the vertical flip platform 20 in the magnetic ring clamping device 100 provided by the utility model includes a vertical fixed plate 21, a vertical rotating plate 22 and a third driving component 23 driving the vertical rotating plate 22 to rotate relative to the vertical fixed plate 21. In this embodiment, the third driving component 23 is fixed to the rear side of the vertical fixed plate 21, and the vertical rotating plate 22 is located at the front side of the vertical fixed plate 21. The third driving component 23 includes a cylinder and a gear rack structure, and the third driving component 23 is used to realize the horizontal rotation of the vertical rotating plate 22 relative to the vertical fixed plate 21. Figure 1 and Figure 2 As shown, the magnetic ring clamping assembly 30 is fixed on the vertical rotating plate 22. The rotation axis of the vertical rotating plate 22 is coaxially arranged with the first axis 11 of the magnetic ring 10, so as to ensure that the magnetic ring 10 clamped by the magnetic ring clamping assembly 30 can be completely flipped horizontally during the rotation of the vertical rotating plate 22, and after the horizontal flipping, the center of the magnetic ring 10 is always located on the same vertical axis.

[0047] Furthermore, the vertical flip platform 20 provided by the utility model also includes a positioning assembly 24 for limiting the relative rotation of the vertical rotating plate 22. During the winding process of the magnetic ring 10, the magnetic ring clamping device 100 provided by the utility model needs to ensure the relative fixation of the magnetic ring 10, that is, to ensure that the magnetic ring 10 will not be horizontally offset, vertically shake, or horizontally flipped as the wire is wound. Therefore, in order to prevent the magnetic ring 10 from horizontally flipping during the winding process, the vertical flip platform 20 also includes a positioning assembly 24 for limiting the horizontal rotation of the vertical rotating plate 22 relative to the vertical fixed plate 21.

[0048] Specifically, Figure 7 As shown, Figure 2A partial enlarged view of point A in the middle. The positioning assembly 24 in the vertical flip platform 20 includes a fourth driving member 241 fixed on the vertical fixed plate 21 and a positioning pin 242 driven by the fourth driving member 241 to move horizontally, and positioning holes 221 are respectively provided on both horizontal sides of the vertical rotating plate 22. Positioning holes 221 are provided on both sides of the vertical rotating plate 22. In the initial state, the fourth driving member 241 drives the positioning pin 242 to be inserted into the positioning hole 221 of the vertical rotating plate 22 to ensure that the vertical rotating plate 22 cannot rotate. When it is necessary to flip the magnetic ring assembly 30, the fourth driving member 241 drives the positioning pin 242 to be pulled out of the positioning hole 221. At this time, the vertical rotating plate 22 can be driven by the third driving assembly 23 to rotate horizontally, thereby realizing the horizontal flipping of the magnetic ring assembly 30. When the magnetic ring assembly 30 completes the horizontal flipping, as shown in FIG. Figure 3 As shown, the fourth driving member 241 drives the positioning pin 242 to move horizontally again and inserts into the positioning hole 221 on the other side of the vertical rotating plate 22, so that the vertical rotating plate 22 cannot rotate. Therefore, when the clamping magnetic ring assembly 30 is working, the fourth driving member 241 drives the positioning pin 242 to insert into the positioning hole 221 of the vertical rotating plate 22, so as to limit the clamping magnetic ring assembly 30 from horizontally flipping.

[0049] The utility model provides a first clamping rod 32 and a second clamping rod 33 of a magnetic ring clamping device 100 extending in a direction parallel to the first axis 11 of the magnetic ring 10, and clamped at both end portions of the first axis 11 of the magnetic ring 10, i.e., the front and rear end portions of the magnetic ring 10, so that the first half ring 13 of the magnetic ring 10 is located on the outside of the magnetic ring clamping assembly 30. The magnetic ring clamping device 100 can clamp the magnetic ring 10 for winding operation without rotating or translating, so that the magnetic ring clamping device 100 will not interfere with the rotatable winding device in the winding machine and affect the winding operation.

[0050] The magnetic ring clamping device 100 provided by the utility model can also be provided with a horizontal moving platform at the bottom thereof to realize the front-back or left-right movement of the magnetic ring clamping assembly 30 in the horizontal direction, so that the magnetic ring clamping device 100 provided by the utility model can be used for magnetic rings 10 structures of different shapes. Alternatively, the magnetic ring clamping device 100 can also be provided with a horizontal rotating platform at the bottom thereof to realize the rotation of the magnetic ring clamping assembly 30 in the horizontal direction, and the rotation axis of the horizontal rotating platform is the center of the magnetic ring 10, so that the magnetic ring clamping device 100 can be used in different winding machines, and can also be applied to the processing requirements of common mode inductors with different winding methods.

When the winding operation is required, the magnetic ring clamping device 100 clamps the magnetic ring from the left side of the magnetic ring 10, and the winding device moves to the right side of the magnetic ring 10 for winding, that is, during the winding operation, the magnetic ring clamping device 100 and the winding device are respectively located on both sides of the first axis 11 of the magnetic ring 10, thereby ensuring that during the winding process, the magnetic ring clamping device 100 and the winding device will not interfere with each other. The magnetic ring clamping device 100 provided by the utility model clamps the front and rear sides of the magnetic ring 10 (i.e., the two end portions of the first axis 11). During the winding process, the magnetic ring clamping device 100 is fixed relative to the winding machine, and the winding device rotates horizontally along the center of the magnetic ring 10, and flips from top to bottom during the rotation process, thereby driving the wire to go around from the top of the magnetic ring 10 along the outside of the magnetic ring 10 to the bottom of the magnetic ring 10, or from the bottom of the magnetic ring 10 along the outside of the magnetic ring 10 to the top of the magnetic ring 10. During the horizontal rotation of the winding device relative to the magnetic ring 10, the magnetic ring clamping device 100 and the winding device are always on both sides of the first axis 11 of the magnetic ring 10.
