Description

Technical Field

[0001] This utility model relates to the field of fully automated winding equipment technology, and in particular to a winding machine. Background Technology

[0002] A winding machine is a semi-automatic or fully automated device that winds metal wire onto a magnetic ring according to specific rules to form a coil. Existing winding machines are widely used in the production and processing of common-mode inductors. Common-mode inductors typically contain at least two symmetrically arranged coils on the same magnetic ring. Depending on the product design, the two coils are wound in the same or opposite directions. Therefore, existing winding machines require two separate wire feeds to complete the winding operation of the two coils when processing common-mode inductors.

[0003] A differential-mode inductor is an inductor specifically designed to suppress differential-mode interference signals in circuits. For example, a single-winding differential-mode inductor consists of a single coil wound on a magnetic ring. When processing a single-winding differential-mode inductor, the winding machine needs to handle the feeding and winding of long wires. Generally, the length of a single feeding of a single-winding differential-mode inductor is at least twice the length of a single feeding of a common-mode inductor. Therefore, existing winding machines, when processing products requiring long feed wires and winding, either cannot perform the long feed wire and winding process because the length of a single wire feed and winding is limited by the overall size of the winding machine; or they need to increase the overall space occupied by the winding machine, especially the height of the winding machine, which requires a significant increase in the height of the winding station to meet the winding of long wires. This doubles the height of the hook device below the winding machine to meet the winding requirements of long wires, resulting in a high winding station (more than 1.5 meters). This makes it difficult for the winding machine operator to observe and control the processing of the winding machine, and is also not conducive to the later maintenance of the winding machine.

[0004] Existing winding machines are only suitable for processing common-mode inductors. Therefore, the current winding machine's feeding operation involves a first feeding operation: cutting off the end of the wire and then winding it around one side of the magnetic ring to form the first coil. The magnetic ring is then flipped, and a second feeding operation is performed, cutting the wire and then winding it around the other side of the magnetic ring to form the second coil. When processing inductors similar to single-winding differential-mode inductors, the winding machine needs to use the same wire to complete multiple turns and layers of winding on the magnetic ring. Furthermore, the feeding operation for processing single-winding differential-mode inductors not only requires increasing the wire feed length but also requires completing the magnetic ring flipping and re-feeding operations without cutting the wire. Therefore, the current winding machine's feeding method cannot achieve the flipping and re-feeding of the magnetic ring without cutting the wire. Utility Model Content

[0005] The purpose of this invention is to address the shortcomings of existing winding machines that cannot achieve the flipping and re-winding of the magnetic ring without cutting the wire when processing a single wire to complete the coil winding of the entire magnetic ring.

[0046] See Figures 1-9 This invention provides a winding machine 100. The winding machine 100 is suitable for automated winding of existing common-mode inductors, especially for multi-layer, multi-turn winding of ultra-large magnetic rings. It is suitable for processing inductors with long feed lines and long windings. The magnetic ring is vertically positioned, and the wire feed direction is horizontal. This allows for adjusting the length of the hook device in the horizontal direction to meet the needs of different wire lengths for feed and winding processing, thus enhancing the versatility of the winding machine 100.

[0047] The winding machine 100 provided by this utility model can also be used for the automated winding of differential mode inductors, especially for the automated winding of single-winding differential mode inductors. The winding machine 100 can complete the winding of the entire magnetic ring in one wire feeding. During the winding and flipping of the magnetic ring, there is no need to cut the wire, so that a complete and continuous coil can be wound on a single magnetic ring.

[0048] Please see Figure 1 This is a three-dimensional structural diagram of the winding machine 100 provided by this utility model. To facilitate the demonstration of the relative positions of its components, the frame has been removed for display. The winding machine 100 provided by this utility model includes a horizontal mounting plate 11 and a vertical mounting plate 12 arranged perpendicularly to each other. The horizontal mounting plate 11 is horizontally arranged and parallel to the horizontal plane. The horizontal mounting plate 11 includes a first direction ( ) arranged along the horizontal plane. Figure 1 (X-axis) and second direction ( Figure 1 The horizontal mounting plate 11 has a first direction (X-axis) along its width and a second direction (Y-axis) along its length. A vertical mounting plate 12 is vertically positioned, parallel to the vertical plane, and fixed to the horizontal mounting plate 11. The vertical mounting plate 12 extends along the first direction of the horizontal mounting plate 11 and is perpendicular to it. A third direction (Y-axis) is also provided on the vertical mounting plate 12 along the vertical plane. Figure 1 (Z-direction). The components on the winding machine 100 provided by this utility model can move along a horizontal or vertical plane, or move in a first direction, a second direction, and / or a third direction. Furthermore, as... Figure 1 As shown, the horizontal mounting plate 11 in the winding machine 100 provided by this utility model includes not only a first plate located on one side of the vertical mounting plate 12, but also a second plate located on the other side of the vertical mounting plate 12. The first plate and the second plate can be integrally formed, or they can be as shown in the diagram. Figure 1 The components are assembled separately as shown. The first and second plates of the horizontal mounting plate 11 are both mounting platforms set parallel to the horizontal plane.

[0049] like Figure 1As shown, the winding machine 100 provided by this utility model also includes a magnetic ring clamping device 20, a magnetic ring flipping device 30, a wire feeding device 40, a wire hooking device 50, a winding device 60, a magnetic ring feeding device 70, and a magnetic ring station switching device 80. Each device plays a different role on the mounting platform of the winding machine 100 and cooperates with each other to realize the automatic feeding of magnetic rings, the automatic feeding of wire, and the automatic winding operation of wire on magnetic rings. Among them, the magnetic ring clamping device 20, the winding device 60, and the magnetic ring station switching device 80 are all fixed on the vertical mounting plate 12 and located on the same side of the vertical mounting plate 12. The magnetic ring clamping device 20 and the winding device 60 are arranged side by side, and the magnetic ring station switching device 80 is fixed above the vertical mounting plate 12. When needed, it descends to the winding station, magnetic ring feeding station, or magnetic ring unloading station to switch the station of the magnetic ring 90. The magnetic ring flipping device 30, wire feeding device 40, wire hooking device 50, and magnetic ring loading device 70 are all fixed on the horizontal mounting plate 11. The magnetic ring flipping device 30 is located below the horizontal mounting plate 11. When the magnetic ring 90 needs to be flipped for rewinding, the magnetic ring flipping device 30 rises from below the horizontal mounting plate 11 to the magnetic ring winding station to flip the magnetic ring 90. The wire feeding device 40, wire hooking device 50, and magnetic ring loading device 70 are all arranged above the horizontal mounting plate 11. At the same time, the wire hooking device 50 and the wire feeding device 40 are located on both sides of the vertical mounting plate 12, and the winding device 60 and the magnetic ring clamping device 20 are located on the same side of the vertical mounting plate 12, between the wire hooking device 50 and the wire feeding device 40.

[0050] Next, combined Figures 2-9 The various components of the winding machine 100 provided by this utility model will be described.

[0051] Please see Figure 2 This is a three-dimensional structural diagram of the magnetic ring clamping device 20 in the winding machine 100 provided by this utility model, when it is installed on the vertical mounting plate 12. The main function of the magnetic ring clamping device 20 in the winding machine 100 is to clamp the magnetic ring 90 and, while clamping the magnetic ring 90, drive the magnetic ring 90 to rotate along its central axis 91. During rotation, the winding device 60 and the hooking device 50 cooperate to complete the winding of the wire onto the magnetic ring 90. The magnetic ring clamping device 20 is installed on the vertical mounting plate 12, which has a magnetic winding station. The magnetic ring clamping device 20 is arranged on the vertical mounting plate 12 and can rotate around the magnetic winding station.

[0052] Specifically, the magnetic ring clamping device 20 includes a first magnetic ring clamp 21 for clamping the magnetic ring 90 and a first rotating platform 22 for driving the first magnetic ring clamp 21 to rotate around the central axis of the magnetic ring 90. The central axis 91 of the magnetic ring 90 is perpendicular to the vertical mounting plate 12, the magnetic ring 90 is arranged along the vertical plane, and the central axis 91 of the magnetic ring 90 is arranged parallel to the horizontal plane.

[0053] The first magnetic ring clamp 21 refers to a component that can automatically clamp and release the magnetic ring 90, for example, as... Figure 2 The two clamping blocks shown are arranged opposite each other, clamping the outer ring surface of the magnetic ring 90 from both sides of its circumference. The two clamping blocks are controlled to open and close by a driving component, which can be a combination of a cylinder, guide rail, and slider as shown in the figure, to allow the two clamping blocks to move towards or away from each other along the diameter of the magnetic ring 90. The first magnetic ring clamp 21 can also have other structures to achieve clamping in the outer circumferential direction of the magnetic ring 90. For example, the two clamping blocks can be hinged in a scissor structure, with one end abutting against the outer ring surface of the magnetic ring 90, and the other end moving towards or away from each other via the driving component. When moving away from each other, the magnetic ring can be clamped; when moving towards each other, the magnetic ring can be released. In the magnetic ring clamping device 20 provided by this utility model, the first magnetic ring clamp 21 only serves to fix the magnetic ring 90 and its specific structure is not limited.

[0054] The first rotating platform 22 is a rotating drive component fixed to the vertical mounting plate 12 and capable of rotating around the central axis 91 of the magnetic ring 90. This first rotating platform 22 can drive the components fixed to it to rotate. The first rotating platform 22 can be as follows: Figure 2 As shown, the arc-shaped guide rail, motor, and slider structure, the first rotating platform 22 is a conventional component used in existing winding machines, which only needs to realize the rotation function, and its specific structure is not limited. The first magnetic ring clamp 21 is fixed on the first rotating platform 22, so that the first rotating platform 22 can drive the first magnetic ring clamp 21 to rotate horizontally, so as to realize the winding operation of the magnetic ring 90.

[0055] Preferably, the magnetic ring clamping device 20 further includes a fifth magnetic ring clamp 23 disposed on the first rotating platform 22 and a ninth translation component 24 for driving the fifth magnetic ring clamp 23 to move horizontally. The function of the fifth magnetic ring clamp 23 is to clamp the magnetic ring 90 on both axial sides, thereby defining the relative axial position of the magnetic ring 90. The structure of the fifth magnetic ring clamp 23 can be as follows: Figure 2 The two clamping plates shown are opened and closed by a cylinder to achieve the operation of clamping the two plates towards each other or releasing them away from each other. The fifth magnetic ring clamp 23 can also be other structures that can achieve axial clamping of the magnetic ring 90. For example... Figure 2As shown, the fifth magnetic ring clamp 23 and the first magnetic ring clamp 21 fix the magnetic ring 90 from different directions (axial and circumferential) and different positions (both ends of the magnetic ring's diameter and both sides of the magnetic ring's end face). The fifth magnetic ring clamp 23 is configured as a more optimized structure, allowing it to move to the side of the magnetic ring 90 for fixation when axial fixation is required, and to maintain a distance from the magnetic ring 90 when axial fixation is not needed, thus avoiding interference with the winding operation of the magnetic ring 90. Furthermore, the ninth translation component 24 is fixed to the first rotating platform 22 and can rotate around the central axis 91 of the magnetic ring 90 along with the first rotating platform 22. The fifth magnetic ring clamp 23 is fixed to the ninth translation component 24 and can translate on the magnetic ring clamping device 20 in a plane parallel to the vertical mounting plate 12, i.e., in a vertical plane. Specifically, the ninth translation component 24 can drive the fifth magnetic ring clamp 23 to translate along the setting direction of the first magnetic ring clamp 21. The function of the ninth translation component 24 is that, when the fifth magnetic ring clamp 23 needs to hold the magnetic ring 90, the ninth translation component 24 drives the fifth magnetic ring clamp 23 to move to the end of the first magnetic ring clamp 21 and clamps the magnetic ring 90 from both axial sides, achieving simultaneous clamping of the axial and circumferential end faces of the magnetic ring 90 by the first magnetic ring component 21 and the fifth magnetic ring clamp 23, thereby better clamping and fixing the magnetic ring 90. When the fifth magnetic ring clamp 23 is not needed to hold the magnetic ring 90, the ninth translation component 24 drives the fifth magnetic ring clamp 23 to move away from the end of the first magnetic ring clamp 21, allowing the fifth magnetic ring clamp 23 to separate from the magnetic ring 90. The ninth translation component 24 is a driving component mounted on the first rotating platform 24 that can drive the fifth magnetic ring clamp 23 to translate; it can be a cylinder and guide rail structure, or a drive motor and guide rail structure.

[0056] Please see Figure 3 This is a three-dimensional structural diagram of the magnetic ring flipping device 30 in the winding machine 100 provided by this utility model. The magnetic ring flipping device 30 is disposed below the horizontal mounting plate 11 of the winding machine 100. When needed, it rises above the horizontal mounting plate 11 to achieve the flipping of the magnetic ring 90 along the vertical plane. During magnetic ring feeding, wire feeding, magnetic ring winding, and magnetic ring hooking, the magnetic ring flipping device 30 is always located below the horizontal mounting plate 11.

[0057] like Figure 1 As shown, the magnetic ring flipping device 30 is disposed on a horizontal mounting plate 11, and the horizontal mounting plate 11 has a through hole through which the magnetic ring flipping device 30 can pass. Figure 3 As shown, the magnetic ring flipping device 30 includes a second magnetic ring clamp 31 that holds the magnetic ring 90, a second rotating platform 32 that drives the second magnetic ring clamp 31 to flip along a vertical plane, and a first moving platform 33 that drives the second magnetic ring clamp 31 to move. In this embodiment, as... Figure 3 As shown, the second magnetic ring clamp 31 consists of two clamping blocks, each clamping a magnetic ring 90 from both axial sides. The second rotating platform 32 is a combined cylinder capable of simultaneously driving the opening and closing of the two clamping blocks and rotating them; that is, the second rotating platform 32 can simultaneously drive the opening, closing, and rotation of the second magnetic ring clamp 31. After the second magnetic ring clamp 31 clamps the magnetic ring 90 from both axial sides, the first magnetic ring clamp 21 of the magnetic ring clamping device 20 releases its grip on the magnetic ring 90, allowing the magnetic ring flipping device 30 to control the magnetic ring 90. Then, the second rotating platform 32 can drive the second magnetic ring clamp 31 to rotate horizontally, thereby flipping the magnetic ring 90 clamped on the second magnetic ring clamp 31.

[0058] The first moving platform 33 can simultaneously control the vertical lifting and horizontal translation of the second rotating platform 32. The first moving platform 33 includes a first lifting component 331 that moves vertically (Z-axis) and a first translation component 332 that moves horizontally (Y-axis). Therefore, the first moving platform 33 can drive the second magnetic ring clamp 31 located on it to move horizontally (Y-axis) and vertically (Z-axis). Specifically, when the magnetic ring flipping device 30 is needed, the first lifting component 331 moves vertically (Z-axis) to move the second magnetic ring clamp 31 to the magnetic ring winding station to clamp the magnetic ring 90. When the magnetic ring 90 needs to be flipped, the first translation component 332 moves horizontally (Y-axis) to separate the magnetic ring 90 from the magnetic ring clamping device 20, thereby achieving the flipping of the magnetic ring 90. Furthermore, the first lifting component 331 and the first translation component 332 on the first moving platform 33 can be as follows: Figure 3 The cylinder, guide rail, and other related structures shown can also be motors, guide rails, sliders, and other related structures used to achieve movement.

[0059] Please see Figure 4This is a three-dimensional structural diagram of the wire feeding component 41 and the second moving platform 42 in the wire feeding device 40 of the winding machine 100 provided by this utility model. The wire feeding device 40 provided by this utility model is used for feeding wire and cutting the wire after feeding. The wire feeding device 40 is set at the horizontal mounting plate 11 and includes a wire feeding component 41 for driving the wire to move horizontally, a second moving platform 42 set on the horizontal mounting plate 11 for driving the wire feeding component 41 to move horizontally, and a wire cutting component 43 for cutting the wire. Among them, the wire feeding component 41 is mainly used for controlling the wire, that is, to realize the automatic feeding of the wire and to fix the wire. When wire movement is required, the wire feeding assembly 41 can provide the power for forward or backward movement of the wire, realizing active wire feeding. It can also release the wire during movement, allowing it to be smoothly removed from the wire feeding assembly 41 by the hook device 50. Furthermore, when wire movement is not required, the wire feeding assembly 41 can provide fixed support to stop the wire from moving. The main function of the wire cutting assembly 43 is to cut the end of the wire after the wire feeding operation is completed, thus completing the wire feeding process.

[0060] Preferably, such as Figure 4 As shown, the wire feeding assembly 41 includes a first guide wheel group 411, a second guide wheel group 412, and a first drive assembly 413 for driving the second guide wheel group 412 to move vertically up and down. The first drive assembly 413 is a drive component that drives the first guide wheel group 411 and the second guide wheel group 412 to move towards or away from each other. The first drive assembly 413 can be a drive cylinder as shown, or other drive components capable of vertical movement. When the first guide wheel group 411 and the second guide wheel group 412 move towards each other until the distance between them is less than the diameter of the wire, the movement of the wire can be restricted by the first guide wheel group 411 and the second guide wheel group 412, meaning the wire cannot move within them. When the first guide wheel assembly 411 and the second guide wheel assembly 412 move towards each other until the distance between them is equal to or slightly larger than the diameter of the wire, the wire can be moved by the movement of the first guide wheel assembly 411 and the second guide wheel assembly 412. When the first guide wheel assembly 411 and the second guide wheel assembly 412 move away from each other until the distance between them reaches twice or more the diameter of the wire, the wire can move freely between the first guide wheel assembly 411 and the second guide wheel assembly 412.

[0061] The first guide wheel assembly 411 includes a lower base and several first guide wheels 4111 arranged in parallel. All first guide wheels 4111 are fixed inside the lower base and can rotate forward or backward within the lower base. The second guide wheel assembly 412 includes an upper base and several second guide wheels 4121 arranged in parallel. All second guide wheels 4121 are fixed inside the upper base and can rotate forward or backward within the upper base. The first guide wheels 4111 and the second guide wheels 4121 correspond one-to-one and are arranged opposite each other in the vertical direction. The first guide wheels 4111 and the second guide wheels 4121 rotate synchronously and in the same direction, and the wire passes between the first guide wheels 4111 and the second guide wheels 4121. The forward rotation of the first guide wheels 4111 and the second guide wheels 4121 drives the wire forward, and the reverse rotation of the first guide wheels 4111 and the second guide wheels 4121 drives the wire backward.

[0062] Preferably, the wire feeding assembly 41 further includes a fixed base 414 disposed on the second moving platform 42 and a second drive assembly 415 disposed on the fixed base 414 to drive all the first guide wheels 4111 to rotate. The fixed base 414 is fixed to the second moving platform 42 and can translate along with the second moving platform 42 on the horizontal mounting plate 11. The first guide wheel set 411, the second guide wheel set 412, and the first drive assembly 413 are all disposed in the fixed base 414. The second drive assembly 415 is fixed inside the fixed base 414. In this embodiment, the second drive assembly 415 is a motor disposed in the fixed base 414, which drives the first guide wheels 4111 to rotate via a motor and a conveyor belt. The first guide wheels 4111 are driving wheels, and the second guide wheels 4121 are driven wheels, so that the first guide wheels 4111 and the second guide wheels 4121 rotate synchronously and in the same direction. The second moving platform 42 includes a second translation assembly 421 and a third translation assembly 422 disposed on the horizontal mounting plate 11. Both the second translation component 421 and the third translation component 422 are drive structures capable of translation operation. The second translation component 421 moves along the width direction of the horizontal mounting plate 11, i.e., the X-axis direction, while the third translation component 422 moves along the length direction of the horizontal mounting plate 11, i.e., the Y-axis direction. The second translation component 421 allows the wire feeding component 41 to change positions on the horizontal mounting plate 11, thereby avoiding interference between the wire feeding component 41 and other devices on the horizontal mounting plate 11.

[0063] Please see Figure 5This is a three-dimensional structural diagram of the wire-feeding device 40 in the winding machine 100 provided by this utility model, showing the wire-cutting assembly 43 and the second lifting assembly 44. The wire-feeding device 40 provided by this utility model also includes a second lifting assembly 44 mounted on a horizontal mounting plate 11 for driving the wire-cutting assembly 43 to move up and down. The second lifting assembly 44 is a driving assembly capable of moving the wire-cutting assembly 43 along the Z-axis in a vertical plane. In this embodiment, the second lifting assembly 44 is a cylinder, guide rail, or other components mounted on the mounting plate. Figure 1 and Figure 5 As shown, in the wire feeding device 40 provided in this utility model, the wire cutting assembly 43 is initially located below the horizontal mounting plate 11. When needed, the wire cutting assembly 43 rises above the horizontal mounting plate 11, and the front end of the wire feeding assembly 41 cuts the wire. In this embodiment, the wire cutting assembly 43 includes a cutter 431 and a drive member 432 for driving the cutter. The wire cutting assembly 43 can be the structure shown in the figure, or it can be a wire cutter commonly used in the prior art of winding machines. The wire cutting assembly 43 can be vertically raised and lowered relative to the horizontal mounting plate 11 along with the second lifting assembly 44.

[0064] Please see Figure 6 This is a side view of the hooking device 50 in the winding machine 100 provided by this utility model. To show the internal structure of the hooking device 50, one side plate 521 of the protective frame 52 has been removed. During the wire input stage of the winding machine 100, the hooking device 50 can hook the wire and complete the automatic wire input operation, and it can also hook the wire and complete the winding operation on the magnetic ring. The hooking device 50 in the winding machine 100 provided by this utility model is located at the horizontal mounting plate 11, as shown below. Figure 1 As shown, the hook device 50 is located on the rear side of the vertical mounting plate 12. The hook device 50 is horizontally arranged, that is, the line moves horizontally inside the hook device 50.

[0065] Specifically, such as Figure 6As shown, the hooking device 50 includes a hook 51 that passes horizontally through the central hole of the magnetic ring 90 to hook the line, a protective frame 52 mounted on a horizontal mounting plate 11, and a third moving platform 53 that drives the hook 51 to move along the extension direction of the protective frame 52. The hook 51 is used to hook the line and guide its movement in the horizontal direction. The protective frame 52 restricts the space for the line to move in the horizontal direction, thereby preventing problems such as winding, tangling, and collision of long lines during the hooking process. The third moving platform 53 drives the hook 51 to move horizontally, allowing the hook to reciprocate along the extension direction of the protective frame 52. The third moving platform 53 drives the hook 51 to move in the vertical direction (Z-axis) with a third lifting component 531 and in the horizontal width direction (X-axis) with a fourth translation component 532. The third lifting component 531 can change the translation height of the hook 51, thereby preventing the hook 51 from colliding with the line located within the protective frame 52 during translation. The fourth translation component 532 allows the hook 51 to shuttle back and forth on the vertical mounting plate 12 and reciprocate along the X-axis direction on the horizontal mounting plate 11.

[0066] like Figure 6 As shown, the protective frame 52 of the hook-line device 50 includes two opposing side plates 521 fixed to a horizontal mounting plate 11, a base plate 522 fixed between the two side plates 521, and a pair of brushes 523 respectively fixed to the top of the two side plates 521. One end of each side plate 521 is fixed to a vertical mounting plate 12, and the other end is fixed to an extension plate of the horizontal mounting plate 11. The side plates 521 of the protective frame 52 include a guide plate 5211 fixedly connected to the vertical mounting plate 12 and a horizontal plate 5212 fixedly connected to the horizontal mounting plate 11. The guide plate 5211 and the horizontal plate 5212 are integrally formed, and the height of the guide plate 5211 gradually decreases from the side closer to the vertical mounting plate 12 to the side farther away from the vertical mounting plate 12. The height of the horizontal plate 5212 remains constant along the extension direction of the protective frame 52. The protective frame 52 of the hook-line device 50 also includes a wire-pressing assembly 524, which is located on the top of the guide plate 5211, and a pair of brushes 523 are located on the top of the horizontal plate 5212. The pair of brushes 523 located on the top of the horizontal plate 5212 can completely seal the top of the space enclosed between the two side plates 521, while ensuring that the third moving platform 53 can move between the pair of brushes 523. The wire-pressing assembly 524 located on the top of the guide plate 5211 can guide the wire when it enters the protective frame 52, pressing the wire down to the bottom plate 522 of the protective frame 52, so that the wire does not have more space to wander inside the protective frame 52.

[0067] Specifically, such as Figure 6As shown, the wire clamping assembly 524 includes a wire clamping plate 5241 hinged to the side plate 521 and a downward pressure drive member 5242 that drives the wire clamping plate 5241 to swing. One end of the wire clamping plate 5241 is hinged to the top of the conductor plate 5211 of the side plate 521, and the other end swings with the downward pressure drive member 5242. When the wire enters the protective frame 52 and the conductor is needed, the downward pressure drive member 52 drives the wire clamping plate 5241 downward, so that the end of the wire clamping plate 5241 abuts against the wire and guides the wire to move within a small height range between the wire clamping plate 5241 and the bottom plate 522, thereby avoiding the problem of long wires winding or tangling after entering the protective frame 52.

[0068] Please see Figure 7 This is a three-dimensional structural diagram of the winding device 60 in the winding machine 100 provided by this utility model. The winding device 60 is disposed on the vertical mounting plate 12, located on the side of the magnetic ring clamping device 20. It is mainly used to reciprocate along the axial direction of the magnetic ring 90 held by the magnetic ring clamping device 20, thereby pulling the wire from one end face of the magnetic ring 90 to the other end face. The winding device 60 includes a fourth moving platform 61 fixed on the vertical mounting plate 12 and a guide wheel 62 driven by the fourth moving platform 61. The fourth moving platform 61, fixed on the vertical mounting plate 12, can drive the guide wheel 62 to move in the X and Y axes of the horizontal plane, and also in the Z axis of the vertical plane, thereby enabling the guide wheel 62 to switch between different positions on the magnetic ring 90, and guiding the wire around the magnetic ring 90.

[0069] Preferably, such as Figure 7 As shown, in this embodiment, the fourth moving platform 61 includes a fourth lifting assembly 611 fixed to the vertical mounting plate 12, a fifth translation assembly 612 disposed on the fourth lifting assembly 611, and a sixth translation assembly 613 disposed on the fifth translation assembly 612. The fourth lifting assembly 611 can achieve vertical lifting, the fifth translation assembly 612 can move along the width direction (X-axis) of the horizontal mounting plate 11 on the horizontal plane, that is, the axial movement of both ends of the magnetic ring 90, and the sixth translation assembly 613 can move along the length direction (Y-axis) of the horizontal mounting plate 11 on the horizontal plane, that is, the radial movement of the magnetic ring 90. The fourth lifting assembly 611, the fifth translation assembly 612, and the sixth translation assembly 613 in the fourth moving platform 61 are all driving components that can achieve movement, such as the motor, guide rail, lead screw, slider, etc. structure in this embodiment, or the motor, guide rail, pulley, slider, etc. structure. Driven by the fourth moving platform 61, the guide wheel 62 can move at any position around the winding station of the winding machine 100, and drive the movement of the wire using the guide wheel 62.

[0070] Please see Figure 8 This is a three-dimensional structural diagram of the magnetic ring feeding device 70 in the winding machine 100 provided by this utility model. The magnetic ring feeding device 70 is disposed on the side of the horizontal mounting plate 11 in the winding machine 100 and is used to feed the magnetic ring 90. During feeding, the magnetic ring 90 is initially fed horizontally. The magnetic ring feeding device 70 provided by this utility model can switch the horizontal placement of the magnetic ring 90 to a vertical placement, thereby ensuring that the magnetic ring 90 is vertically positioned when the magnetic ring clamping device 20 clamps the magnetic ring 90 at the magnetic winding station.

[0071] like Figure 8 As shown, the magnetic ring feeding device 70 includes a magnetic ring conveyor belt 71 and a magnetic ring feeding seat 72 disposed on a horizontal mounting plate 11, and a magnetic ring flipping assembly 73 disposed on the horizontal mounting plate 11. The magnetic ring flipping assembly 73 flips the magnetic rings 90 placed horizontally on the magnetic ring conveyor belt 71 along the horizontal plane and moves them to the magnetic ring feeding seat 72. The conveyor belt on the magnetic ring conveyor belt 71 continuously transports the magnetic rings 90 from the outside of the winding machine 100 into the horizontal mounting plate 11. Then, the magnetic ring flipping assembly 73 flips the magnetic rings 90 placed horizontally on the magnetic ring conveyor belt 71 by 90° and moves them to the magnetic ring feeding seat 72. In this embodiment, the magnetic ring feeding seat 72 is a magnetic ring feeding station that fixes and supports the magnetic rings 90 when they are placed vertically. At the magnetic ring feeding station, the magnetic rings 90 are placed vertically to facilitate the subsequent feeding of magnetic rings 90. Each magnetic ring feeding seat 72 is only for placing one magnetic ring 90.

[0072] Specifically, the magnetic ring flipping assembly 73 includes a third magnetic ring clamp 731 that holds the magnetic ring 90 within the central hole of the magnetic ring 90; a seventh translation assembly 732 that drives the third magnetic ring clamp 731 to lift or translate; a third rotating platform 733 that rotates the third magnetic ring clamp 731; and an eighth translation assembly 734 that translates the third magnetic ring clamp 731 to the magnetic ring loading seat 72. Under the action of the seventh translation assembly 732, the third magnetic ring clamp 731 can lift the magnetic ring 90 from the magnetic ring conveyor belt 71, realizing the separation of the magnetic ring 90 from the magnetic ring conveyor belt 71. Then, under the action of the third rotating platform 733, the seventh translation assembly 732 and the third magnetic ring clamp 731 rotate synchronously by 90°, and the magnetic ring 90 flips from a horizontal state to a vertical state. Finally, the eighth translation component 734 drives the third magnetic ring clamp 731 to move along the width direction (X-axis) of the horizontal mounting plate 11, so that the magnetic ring 90 is placed on the magnetic ring loading seat 72 and clamped by the magnetic ring loading seat 72.

[0073] Please see Figure 9This is a three-dimensional structural diagram of the magnetic ring station switching device 80 in the winding machine 100 provided by this utility model. The magnetic ring station switching device 80 is disposed above the vertical mounting plate 12 of the winding machine 100 and is used to move the magnetic ring 90 to different stations. That is, the magnetic ring station switching device 80 can move the magnetic ring 90 from the magnetic ring loading seat 72 to the first magnetic ring clamp 21 of the magnetic ring clamping device 20, and can also move the magnetic ring 90 from the first magnetic ring clamp 21 of the magnetic ring clamping device 20 to the unloading station.

[0074] like Figure 9 As shown, the magnetic ring station switching device 80 includes a horizontal moving component 81 mounted on a vertical mounting plate 12, a fifth lifting component 82 driven by the horizontal moving component 81, and a fourth magnetic ring clamp 83 mounted on the fifth lifting component 82. In this embodiment, the winding machine 100 is provided with a magnetic ring loading station on the magnetic ring loading seat 72, a magnetic ring winding station on the magnetic ring clamping device 20, and a lower magnetic ring station. Therefore, it is necessary to switch the two magnetic rings 90 on the three stations simultaneously. Thus, two fifth lifting components 82 and two fourth magnetic ring clamps 83 are simultaneously provided on the magnetic ring station switching device 80. The fifth lifting component 82 drives the fourth magnetic ring clamp 83 to move vertically. When station switching is required, the fourth magnetic ring clamp 83 moves downward to the corresponding station, clamps the magnetic ring 90 from the center hole of the magnetic ring 90, and drives the magnetic ring 90 to move to the next station with the drive of the horizontal moving component 81, thereby completing the switching of the magnetic ring 90 at different stations.

[0075] like Figure 9 As shown, the magnetic ring station switching device 80 also includes a sixth lifting assembly 84 driven by a horizontal moving assembly 81 and a wire-blocking frame 85 disposed on the sixth lifting assembly 84. The wire-blocking frame 85 is mainly used during the winding operation. When the wire-blocking frame 85 moves to the axial side of the magnetic ring 80 near the wire feeding device 40, and the wire wheel 62 of the winding device 60 brings the wire from one axial side of the magnetic ring 90 around the outer circumference of the magnetic ring 90 to the other side of the magnetic ring 90, the wire will enter the wire-blocking frame 85, preventing the wire from flying randomly into other areas of the winding machine 100. On the one hand, it can limit the movement of the free end of the wire to protect the wire from damage. On the other hand, it can also protect the wire feeding device 40 at the front of the winding machine 100, preventing the wound wire from getting tangled with the wire of the wire feeding device 40 and knotting.

[0076] The present invention provides a winding machine 100 in which the magnetic ring 90 at the winding station is set vertically, thereby changing the wire feeding direction of the winding machine 100 and making the wire feed horizontally, passing from one axial end of the magnetic ring 90 through the central hole of the magnetic ring 90 to the other axial end of the magnetic ring 90. This wire feeding method can adjust the wire feeding length of the magnetic ring 90 during winding by adjusting the moving distance of the hook device 50 of the winding machine 100. Moreover, this wire feeding method can be applied to the wire feeding requirements of different lengths, and can meet the winding processing requirements of the magnetic ring 90 with long wire feeding and long winding without changing the operating table height of the winding machine 100.

[0077] The winding machine 100 provided by this utility model can perform two-stage wire feeding on the magnetic ring 90, and there is no need to cut the wire between the two stages of wire feeding. This makes the winding machine 100 provided by this utility model not only suitable for the automated processing of common mode inductors, but also suitable for the automated processing of differential mode inductors, especially suitable for the automated processing of single-winding differential mode inductors.

[0078] The above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although this utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of this utility model, and should all be included within the protection scope of this utility model.
