Description

Technical Field

[0001] This invention relates to the field of common-mode inductor technology, and in particular to a high-ripple-suppression common-mode inductor for data center power supplies and its processing apparatus. Background Technology

[0002] A common-mode inductor is an inductor used to suppress common-mode interference. It is widely used in EMI filtering circuits of electronic devices such as power adapters, chargers, frequency converters, and home appliance control boards. The currents flowing through the two windings are in opposite directions, and the magnetic fluxes they generate cancel each other out. Therefore, it has almost no obstruction to differential-mode signals (normal operating current). For common-mode signals (such as external electromagnetic interference and noise), the magnetic fluxes generated by the two windings are superimposed in the same direction, presenting a high impedance, thereby suppressing common-mode noise. However, in actual use, especially in data center power supplies, ordinary common-mode inductors cannot adapt to the complex working environment of data center power supplies. During the use of data center power supplies, the ripple amplitude gradually decreases, making the power output less likely to be close to pure DC, ultimately reducing the stability and electromagnetic compatibility of the equipment. At the same time, in the process of common-mode inductor manufacturing, in order to improve the service life of the common-mode inductor, after the wires are wound, a wire pressing wheel is used to further flatten the wires. The traditional wire pressing method is to place the wire pressing wheel directly on the side wall of the winding and move the wire pressing wheel up and down to complete the flattening operation. However, using this wire pressing method, the flattening effect is generally poor, and the force on the wires remains constant, making it very easy to damage the wires in the early stages of wire pressing. Therefore, this paper provides a high ripple suppression common-mode inductor for data center power supplies and a manufacturing device for it. Summary of the Invention

[0003] The purpose of this invention is to address the shortcomings of existing technologies by providing a high ripple suppression common-mode inductor and its processing apparatus for data center power supplies.

[0004] The present invention adopts the following technical solution: A high ripple suppression common-mode inductor for data center power supplies includes a frame, two magnetic cores symmetrically fixedly connected within the frame, multiple windings wound around the two magnetic cores, the ends of the multiple windings being fixedly connected to the frame, and pins being fixedly connected to the ends of the multiple windings. Two fixing plates are fixedly connected to both sides of the frame, and fixing bolts are commonly fitted onto the two fixing plates. Fixing nuts are threaded onto the outer side of the fixing bolts.

[0005] A processing apparatus for a high ripple suppression common-mode inductor for data center power supplies includes a processing table, a winding assembly fixedly connected to the processing table, and a wire clamping assembly fixedly mounted on the processing table. The wire pressing assembly can organize segmented windings, straighten the wires to both sides, and reduce stacking and jumpers. The pressing assembly includes a fixed plate fixedly mounted on a processing table. A first hydraulic cylinder is fixedly mounted on the fixed plate. A movable plate is fixedly connected to the output end of the first hydraulic cylinder. A control motor is fixedly connected to the movable plate. An eccentric plate is fixedly connected to the output shaft end of the control motor. An eccentric rod is fixedly connected to the eccentric plate. A movable frame is sleeved on the eccentric rod. The movable frame and the movable plate are slidably connected. First connecting rods are rotatably connected to both ends of the movable frame. Movable rods are rotatably sleeved on the first connecting rods. Movable rods are slidably connected to the movable plate. A movable cylinder is slidably sleeved on the movable rod. A clamping frame is fixedly connected to the movable cylinder. A clamping plate is slidably mounted on the clamping frame. A pressing wheel is rotatably connected inside the clamping plate. The movable plate has two arc-shaped grooves. A sliding rod is slidably connected to the arc-shaped grooves. The sliding rod is fixedly connected to the movable cylinder. A control component for controlling the position of the sliding rod is mounted on the movable plate.

[0006] Preferably, the control component includes two second hydraulic cylinders fixedly mounted on the upper side of the movable plate, the output ends of the two second hydraulic cylinders are fixedly connected to a circular plate, the slide rod is sleeved with a limit frame, a telescopic connecting rod is fixedly connected between the circular plate and the limit frame, and a first spring is also fixedly connected between the circular plate and the limit frame.

[0007] Preferably, the clamping frame has a control groove, a control block is slidably connected in the control groove, the control block is fixedly connected to the clamping plate, a third hydraulic cylinder is fixedly connected in the control groove, a control plate is fixedly installed at the output end of the third hydraulic cylinder, and a second spring is fixedly connected between the control plate and the control block.

[0008] Preferably, the clamping frame is fixedly equipped with an obstruction component. The obstruction component can reduce the force of the pressure wheel on the winding when the pressure wheel initially comes into contact with the winding. Then, after a period of time after the initial pressure is started, it loses its obstruction on the pressure wheel, ultimately achieving the effect of low pressure in the early stage of pressure to avoid damaging the wire, and high pressure in the later stage of pressure to compact the winding.

[0009] Preferably, the obstruction component includes a limiting groove on the outside of the clamping frame, a limiting block is slidably connected in the limiting groove, a second connecting rod is fixedly connected to the limiting block, a third connecting rod is rotatably connected to the second connecting rod, an installation rod is rotatably connected to the third connecting rod, and the installation rod is fixedly connected to the clamping plate.

[0010] Preferably, the clamping plate is rotatably connected to a rotating cylinder, the rotating cylinder is fixedly connected to a driven gear, the third connecting rod is fixedly connected to a half gear, the half gear and the driven gear are meshed together, and the rotating cylinder is fixedly connected to a camera.

[0011] Preferably, the movable plate has a movable groove, and the movable rod and the movable groove are slidably connected.

[0012] The beneficial effects of this invention are: 1. First, the number of segments, turns, and layer spacing of the windings on both sides are completely consistent, making the resistance, inductance, and distributed capacitance of the windings on both sides highly consistent, significantly improving the common-mode rejection ratio, which can more effectively suppress common-mode interference and ensure the electrical and physical symmetry of the windings. Furthermore, the layer spacing between segments is equivalent to artificially introducing a controllable air gap, thereby precisely controlling the leakage inductance. The segmented structure reduces the parasitic capacitance between layers of the windings, reducing the coupling loss of high-frequency signals, allowing the inductor to maintain stable filtering performance over a wide frequency range. The tight arrangement of segments and layers makes the windings fit more firmly, reducing vibration and howling caused by magnetostriction, making it particularly suitable for high-power, high-ripple applications. 2. Secondly, when processing high ripple suppression common mode inductors, especially during the winding process, the pressure wheel moves along a specific trajectory under the action of the arc-shaped groove. This not only flattens the wires, but also straightens them to both sides when the pressure wheel moves back and forth. This is particularly suitable for the inter-segment steps during segmented winding, which can significantly reduce stacking and wire skipping. Furthermore, the pressure wheel moves dynamically during the pressure operation, rather than pressing rigidly, which can make the winding 3 tight, the segment height consistent, and the leakage inductance stable, making it more suitable for processing high ripple suppression common mode inductors. 3. Then, during the wire pressing process, the pressure should be low in the early stage to avoid damaging the wire, and high in the later stage to improve the effect of compacting the winding.

Detailed Implementation

[0015] See Figure 1 A high ripple suppression common-mode inductor for data center power supplies includes a frame 1, two magnetic cores 2 are symmetrically fixedly connected inside the frame 1, and multiple windings 3 are wound around the outside of the two magnetic cores 2. The ends of the multiple windings 3 are fixedly connected to the frame 1, and pins 4 are fixedly connected to the ends of the multiple windings 3. Two fixing plates 5 are fixedly connected to both sides of the frame 1, and fixing bolts 6 are sleeved on the two fixing plates 5. Fixing nuts 7 are threaded to the outside of the fixing bolts 6. First, such as Figure 1As shown, the windings 3 on both sides adopt a segmented layered structure. First, winding 3 is divided into multiple segments with a fixed interlayer spacing, replacing the traditional tightly wound whole segment. Furthermore, the number of segments, turns, and interlayer spacing of windings 3 on both sides are completely consistent, ensuring that the resistance, inductance, and distributed capacitance of windings 3 on both sides are highly uniform. This significantly improves the common-mode rejection ratio, effectively suppressing common-mode interference and ensuring the electrical and physical symmetry of winding 3. The interlayer spacing between segments is equivalent to artificially introducing a controllable air gap, thereby precisely controlling the leakage inductance. The segmented structure reduces the interlayer parasitic capacitance of winding 3, lowering... The coupling loss of high-frequency signals is reduced, allowing the inductor to maintain stable filtering performance over a wide frequency range. The segmented and layered close arrangement makes the winding 3 fit more firmly, reducing vibration and howling caused by magnetostriction. It is particularly suitable for high-power, high-ripple applications. Furthermore, during the use of the device, especially when multiple devices are used, multiple devices can be arranged in sequence, with the fixing plates 5 on the outside of two adjacent devices facing each other. Then, the fixing bolts 6 are screwed into the fixing plates 5, and the fixing nuts 7 are rotated to complete the installation and fixing of the two adjacent devices.

[0016] See Figures 2-10 A processing apparatus for a high ripple suppression common-mode inductor for data center power supplies includes a processing table 8, on the upper side of which a winding assembly is fixedly connected. The winding assembly includes a fixed frame 9 fixedly mounted on the upper side of the processing table 8, a rotating wheel 11 rotatably mounted on the side wall of the fixed frame 9, a tension controller 10 fixedly mounted on the side wall of the fixed frame 9, a tension control wheel fixedly mounted on the output end of the tension controller 10, a fixed wheel 12 rotatably mounted on the upper side of the processing table 8, a robotic arm fixedly mounted inside the fixed wheel 12, and multiple fixed motors fixedly mounted circumferentially inside the fixed wheel 12. During the processing of high ripple suppression common mode inductors, when wire winding is required, the magnetic core 2 is first fixed on the output shaft of the fixed motor. The wire wound around the outside of the rotating wheel 11 is pulled, allowing the wire to pass through the tension control wheel and be wound on the magnetic core 2. Then, the fixed motor is started, and with the assistance of the robotic arm, the wire is wound on the magnetic core 2, thus completing the winding operation. During the winding process, the tension controller 10 can drive the tension control wheel to move, thereby adjusting the tension of the wire, ultimately making the number of segments, number of turns, and layer spacing of the windings 3 on both sides completely consistent.

[0017] A wire pressing assembly is fixedly installed on the upper side of the processing table 8. The wire pressing assembly can sort out the segmented windings 3, straighten the wires to both sides, and reduce stacking and jumpers. The crimping assembly includes a fixed plate 13 fixedly mounted on the upper side of the processing table 8. A first hydraulic cylinder 14 is fixedly mounted on the side wall of the fixed plate 13. A movable plate 15 is fixedly connected to the output end of the first hydraulic cylinder 14. A control motor 18 is fixedly connected to the movable plate 15. An eccentric plate is fixedly connected to the end of the output shaft of the control motor 18. An eccentric rod 22 is fixedly connected to the side wall of the eccentric plate. A movable frame 25 is sleeved on the outside of the eccentric rod 22. The movable frame 25 and the movable plate 15 are slidably connected. A first connecting rod 23 is rotatably connected to both ends of the movable frame 25. A connecting rod 23 is rotatably sleeved with a movable rod 17. The movable rod 17 and the movable plate 15 are slidably connected. A movable cylinder 30 is slidably sleeved on the outside of the movable rod 17. A clamping frame 31 is fixedly connected to the side wall of the movable cylinder 30. A clamping plate 37 is slidably installed on the side wall of the clamping frame 31. A pressure wheel 19 is rotatably connected inside the clamping plate 37. Two arc-shaped grooves 16 are opened on the side wall of the movable plate 15. A sliding rod 29 is slidably connected in each of the two arc-shaped grooves 16. The sliding rod 29 and the movable cylinder 30 are fixedly connected. A control component for controlling the position of the sliding rod 29 is installed on the upper side of the movable plate 15. The control assembly includes two second hydraulic cylinders 20 fixedly installed on the upper side of the movable plate 15. The output ends of the two second hydraulic cylinders 20 are fixedly connected to a circular plate 26. A sliding rod 29 is sleeved on a limit frame 47. A telescopic connecting rod 27 is fixedly connected between the circular plate 26 and the limit frame 47. A first spring 28 is also fixedly connected between the circular plate 26 and the limit frame 47. A moving groove 24 is opened on the outer side of the movable plate 15. The moving rod 17 is slidably connected to the moving groove 24. A telescopic sleeve 21 is fixedly connected between the movable plate 15 and the movable frame 25. Under the action of the telescopic sleeve 21, the movable frame 25 and the movable plate 15 are slidably connected. First, during the winding process, after each section is wound, the wound conductor needs to be flattened to ensure a tighter fit between the winding 3 and the wall, eliminating uneven tension caused by start-stop cycles and preventing bulges, steps, and stacking at the segment junctions. This also ensures a smoother starting point for the next section, improving leakage inductance stability. The first hydraulic cylinder 14 is then activated, driving the moving plate 15. The moving plate 15, via the moving groove 24, drives the moving rod 17, which in turn drives the moving cylinder 30. The moving cylinder 30 then drives the clamping frame 31, which in turn drives the clamping plate 37. The clamping plate 37 then drives the pressure wheel 19 until the pressure wheel 19 comes into contact with the wound conductor. Close the first hydraulic cylinder 14, then start the control motor 18. The control motor 18 drives the eccentric plate to rotate, which in turn drives the eccentric rod 22 to rotate. Under the action of the telescopic sleeve 21, the moving frame 25 moves back and forth. The moving frame 25 drives the moving rod 17 to move via the first connecting rod 23. Under the constraint of the moving groove 24, refer to the attached... Figure 5As shown, when the movable frame 25 moves back and forth, the first connecting rod 23 causes the two movable rods 17 to move closer or further apart, ultimately driving the movable rods 17 to move back and forth. The movable rods 17 drive the movable cylinder 30 to move back and forth, the movable cylinder 30 drives the clamping frame 31 to move back and forth, the clamping frame 31 drives the clamping plate 37 to move back and forth, and the clamping plate 37 drives the wire pressing wheel 19 to move back and forth. The wire pressing wheel 19 abuts against the wire, forming a flattening operation on the wire. Furthermore, during this process, before each flattening operation, the second hydraulic cylinder 20 is activated according to the width of the wound wire. The second hydraulic cylinder 20 moves the circular plate 26. However, since the sliding rod 29 is located within the arc-shaped groove 16 at this time, the limiting frame 47 remains stationary due to the restraint of the sliding rod 29 and the arc-shaped groove 16. Therefore, when the second hydraulic cylinder 20 moves the circular plate 26, it causes the first spring 28 to deform. When the control motor 18 is activated, under the action of the deformed first spring 28, the sliding rod 29 will eventually move along the arc-shaped groove 16. In this process, Figure 5 From the perspective of the sliding rod 29, when it is about to move to the area where the distance between the two bow-shaped grooves 16 is the farthest, the pressure wheel 19 disconnects from the wire. Then, after the sliding rod 29 moves up or down along the bow-shaped groove 16, the pressure wheel 19 comes into contact with the wire again. This not only flattens the wire, but also straightens the wire to both sides when the pressure wheel 19 moves back and forth. It is particularly suitable for the inter-segment steps in segmented winding, which can significantly reduce stacking and wire skipping. Moreover, when performing the pressure operation, the pressure wheel 19 moves dynamically instead of pressing rigidly, which can make the winding 3 tight, the segment height consistent, and the leakage inductance stable. It is more suitable for the processing of high ripple suppression common mode inductors.

[0018] A control groove 45 is opened on the side wall of the clamping frame 31. A control block 42 is slidably connected in the control groove 45. The control block 42 is fixedly connected to the clamping plate 37. A third hydraulic cylinder 43 is fixedly connected in the control groove 45. A control plate 44 is fixedly installed at the output end of the third hydraulic cylinder 43. A second spring 46 is fixedly connected between the control plate 44 and the control block 42. Before crimping, the third hydraulic cylinder 43 can be activated according to the actual working conditions. The third hydraulic cylinder 43 drives the control plate 44 to move, thereby adjusting the elasticity between the control plate 44 and the control block 42. During the subsequent crimping process, the second spring 46 provides a certain buffering effect to reduce damage to the wire. By activating the third hydraulic cylinder 43 to adjust the position of the control plate 44, the elasticity of the second spring 46 is adjusted, thereby adjusting the buffering effect. Ultimately, the crimping effect is maintained without causing excessive damage to the wire.

[0019] An obstruction component is fixedly installed on the outside of the clamping frame 31. The obstruction component can reduce the force exerted by the pressure roller 19 on the winding 3 when the pressure roller 19 initially comes into contact with the winding 3. Then, after a period of time during the initial pressure process, it loses its obstruction on the pressure roller 19. Ultimately, this achieves the effect of low pressure in the early stages of pressure to avoid damaging the wire, and high pressure in the later stages to compact the winding 3. The obstruction assembly includes a limiting groove 40 on the outside of the clamping frame 31, a limiting block 41 slidably connected in the limiting groove 40, a second connecting rod 32 fixedly connected to the outside of the limiting block 41, a third connecting rod 33 rotatably connected to the outside of the second connecting rod 32, an installation rod 34 rotatably connected to the side wall of the third connecting rod 33, the installation rod 34 and the clamping plate 37 fixedly connected, a rotating cylinder 39 rotatably connected to the outside of the clamping plate 37, a driven gear 36 fixedly connected to the outside of the rotating cylinder 39, a half gear 35 fixedly connected to the outside of the third connecting rod 33, the half gear 35 and the driven gear 36 meshing, and a camera 38 fixedly connected to the outside of the rotating cylinder 39. When the wire pressing operation begins, the second connecting rods 32 on both sides are in abutting state. At this time, under the action of the second connecting rods 32 and the third connecting rods 33, the clamping plate 37 will move towards the clamping frame 31. The clamping plate 37 drives the control block 42 to move towards the clamping frame 31. The control block 42 compresses the second spring 46. In the subsequent wire pressing process, the two second connecting rods 32 gradually disconnect, ultimately forming the effect of low pressure in the early stage of wire pressing to avoid damaging the wire, and high pressure in the later stage of wire pressing to compact the winding 3. Furthermore, during the wire pressing process, the camera 38 continuously captures images of the winding 3. The camera 38 can transmit the captured data to the controller, allowing the operator to observe the actual winding situation. Based on the actual winding situation, the operator can restart the second hydraulic cylinder 20, which in turn moves the control board 44, thereby adjusting the deformation of the second spring 46 and ultimately adjusting the wire pressure. Then, during the pressing process, as the second connecting rod 32 moves, it drives the third connecting rod 33 to move, causing the third connecting rod 33 to rotate around the mounting rod 34. The third connecting rod 33 drives the half gear 35 to rotate, the half gear 35 drives the driven gear 36 to rotate, the driven gear 36 drives the rotating cylinder 39 to rotate, and the rotating cylinder 39 drives the camera 38 to rotate, which can expand the shooting range of the camera 38 and thus improve the subsequent adjustment effect.

[0020] In this invention, when wire winding is required, the magnetic core 2 is first fixed on the processing table 8, and the winding operation begins on the processing table 8. During the winding process, after each section is wound, the wound wire needs to be flattened. The first hydraulic cylinder 14 is activated, which drives the moving plate 15 to move. The moving plate 15 drives the moving rod 17, moving cylinder 30, clamping frame 31, clamping plate 37, and pressure wheel 19 to move through the moving groove 24 until the pressure wheel 19 comes into contact with the wound wire. Then, the first hydraulic cylinder 14 is closed, and the control motor 18 is started. The control motor 18 drives the eccentric plate to rotate, and the eccentric plate drives the eccentric rod 22 to rotate. Under the action of the telescopic sleeve 21, the moving frame 25, the first connecting rod 23, and the moving rod 17 move. Under the restriction of the moving groove 24, the two moving rods 17 move closer or further apart, ultimately driving the moving rod 17, the moving cylinder 30, the clamping frame 31, the clamping plate 37, and the wire pressing wheel 19 to move back and forth. The wire pressing wheel 19 abuts against the wire, forming a flattening operation on the wire. Furthermore, during this process, before each flattening operation, the second hydraulic cylinder 20 is activated according to the width of the wound wire. The second hydraulic cylinder 20 moves the circular plate 26. However, since the slide rod 29 is located within the arc-shaped groove 16 at this time, the first spring 28 will deform. When the control motor 18 is activated, under the action of the deformed first spring 28, the slide rod 29 will eventually move along the arc-shaped groove 16. During this process, when the slide bar 29 is about to move to the area where the distance between the two bow-shaped grooves 16 is the farthest, the pressure wheel 19 disconnects from the wire. Then, after the slide bar 29 moves up or down along the bow-shaped groove 16, the pressure wheel 19 comes into contact with the wire again. This not only flattens the wire, but also straightens the wire to both sides when the pressure wheel 19 moves back and forth. When the pressing operation begins, the second connecting rods 32 on both sides are in abutting state. At this time, under the action of the second connecting rods 32 and the third connecting rods 33, the clamping plate 37 will move towards the clamping frame 31. The clamping plate 37 will drive the control block 42 to move towards the clamping frame 31. The control block 42 will compress the second spring 46. In the subsequent pressing process, the two second connecting rods 32 will gradually disconnect, ultimately forming the effect of low pressure in the early stage of pressing to avoid damaging the wire, and high pressure in the later stage of pressing. During the pressing process, as the second connecting rod 32 moves, it drives the third connecting rod 33 to move, causing the third connecting rod 33 to rotate around the mounting rod 34. The third connecting rod 33 drives the half gear 35 to rotate, the half gear 35 drives the driven gear 36 to rotate, the driven gear 36 drives the rotating cylinder 39 to rotate, and the rotating cylinder 39 drives the camera 38 to rotate, which can expand the shooting range of the camera 38 and thus improve the subsequent adjustment effect.
