Description

Technical Field

[0001] This application relates to the field of inductor coil winding equipment, and in particular to a universal winding machine for round and flat wires. Background Technology

[0002] Inductor coils typically require copper wire to be wound around a magnetic core to form a coil structure. Depending on product specifications and electrical performance requirements, the copper wire used can be either round wire with a circular cross-section or flat wire with a flat cross-section. In existing winding equipment, round wire and flat wire differ in cross-sectional shape, guiding method, lead-out posture, and stress state during winding, and are usually processed using different wire-laying devices or different winding equipment. For round wire, its cross-sectional directionality is relatively weak, and conventional guide rollers and wire nozzles can complete the guidance. For flat wire, its width direction needs to remain relatively stable. If deflection or flipping occurs during lead-out, it can easily cause unstable winding posture, uneven coil layer arrangement, and even affect subsequent lead forming and welding quality. Therefore, current production often requires separate equipment or replacement of many wire components for round and flat wires, resulting in long changeover times, low equipment utilization, and poor production continuity.

[0003] Meanwhile, some existing winding equipment uses a method of fixing one end of the magnetic core or wire and rotating the other side separately to achieve winding. Although this method can complete the basic winding action, the winding efficiency is limited. Furthermore, when it is necessary to use both round and flat wires, it is difficult to keep the wire laying direction, wire exit position, and fly fork clamping position consistent. If two independent wire nozzles are simply added to the equipment, the wire exit port of the round wire and the wire exit port of the flat wire are likely to correspond to different spatial positions, which will cause the wire path before entering the fly fork claw to change, thereby increasing the problem of fly fork clamping deviation and inconsistent winding posture. Summary of the Invention

[0004] This application proposes a universal winding machine for round and flat wires, which has the advantage of reducing the workload of readjusting the entire wire arrangement mechanism or replacing the winding equipment when changing types. It solves the problems of low changeover efficiency, difficulty in unifying the wire exit position, and low efficiency of traditional winding methods in existing winding equipment, which usually require separate equipment or replacement of complex wire arrangement components for round and flat wires.

[0005] To achieve the above objectives, this application adopts the following technical solution: A universal winding machine for round and flat wires, comprising a frame, a support plate on the frame, a wire roller for feeding wire and a servo tensioner for adjusting wire tension on the support plate, characterized in that a movable seat is provided on the support plate, a switching mounting plate is provided on the movable seat, an extension plate is provided on the switching mounting plate, and a rotating shaft is rotatably connected to the extension plate; a round wire adjustment mounting plate and a flat wire adjustment mounting plate are provided on the rotating shaft, the round wire adjustment mounting plate forms a round wire outlet for outputting round wire, and the flat wire adjustment mounting plate forms a flat wire outlet for outputting flat wire; a flying fork spindle is provided on the support plate, a flying fork claw is provided on the flying fork spindle, a positioning block is provided on one side of the flying fork claw, and the housing of the flying fork spindle... A wire exit limiting groove is provided; the rotating shaft can rotate relative to the extension plate, and drive the round wire adjustment mounting plate and the flat wire adjustment mounting plate to rotate relative to the extension plate, so that the round wire exit or the flat wire exit can be selectively switched to the exit station corresponding to the same wire exit limiting groove; at the corresponding exit station, the outlet center of the round wire exit or the outlet center of the flat wire exit is located in the same exit reference plane as the groove center of the wire exit limiting groove, and the exit direction of the round wire exit or the flat wire exit is towards the entrance of the wire exit limiting groove; the round wire exit and the flat wire exit have different offsets relative to the axis of the rotating shaft to compensate for the height difference between the center of the round wire and the flat wire cross sections, so that the round wire or flat wire adjusted by the servo tensioner can enter the clamping area of ​​the flying fork claw.

[0006] Furthermore, a mounting base is fixedly provided on the extension plate, a limit ring is provided on the mounting base, a movable rod is movably provided inside the mounting base, the movable rod is connected to a connecting plate, and the connecting plate is connected to the handle through a connecting shaft; the handle can drive the connecting plate and the movable rod to move through the connecting shaft, and the limit ring is used to restrict the movement direction of the movable rod, so that the movable rod can move in a direction close to or away from the rotation axis.

[0007] Furthermore, the rotating shaft has a rectangular mounting section for mounting the round wire adjustment mounting plate and the flat wire adjustment mounting plate, and a hollow cylindrical limiting section for cooperating with the moving rod; the round wire adjustment mounting plate and the flat wire adjustment mounting plate are respectively provided with rectangular mounting holes that match the rectangular mounting section, and the round wire adjustment mounting plate and the flat wire adjustment mounting plate are sleeved on the rectangular mounting section through the corresponding rectangular mounting holes, forming a circumferential linkage with the rotating shaft; the hollow cylindrical limiting section is provided with a guide groove, and the guide groove is threaded. The guide groove includes a round wire positioning section, a flat wire positioning section, and a transition guide section connecting the round wire positioning section and the flat wire positioning section. One end of the moving rod is provided with a protrusion that fits into the guide groove. The moving rod extends into or retracts from the guide groove, thereby driving the rotating shaft to rotate. When the moving rod extends into the round wire positioning section, the round wire outlet is maintained at the outlet position corresponding to the outlet limiting groove. When the moving rod extends into the flat wire positioning section, the flat wire outlet is maintained at the outlet position corresponding to the outlet limiting groove.

[0008] Furthermore, the circular wire adjustment mounting plate is provided with a circular wire guide wheel and a circular wire adjustment rod. The circular wire guide wheel is located on the inlet side of the circular wire outlet, and the circular wire adjustment rod is disposed between the circular wire guide wheel and the circular wire outlet. The circular wire output by the servo tensioner passes through the circular wire guide wheel and the circular wire adjustment rod in sequence, and is then output from the circular wire outlet to the outlet limiting groove.

[0009] Furthermore, the flat wire adjustment mounting plate is equipped with a flat wire guide wheel, a flat wire adjustment rod, a flat wire limiting plate, and a flat wire spacing adjustment rod. The flat wire guide wheel is located on the inlet side of the flat wire outlet. The flat wire limiting plate is disposed between the flat wire guide wheel and the flat wire outlet. The flat wire spacing adjustment rod cooperates with the flat wire limiting plate. The flat wire limiting plate forms a posture-limiting channel for the flat wire to pass through. The width direction of the posture-limiting channel corresponds to the width direction of the flat wire, which is used to prevent the flat wire from flipping or swaying before entering the flat wire outlet. The flat wire spacing adjustment rod is used to adjust the spacing of the posture-limiting channel. When the rotating shaft rotates to align the flat wire outlet with the outlet limiting groove, the attitude limiting channel enters the outlet reference plane along with the flat wire adjustment mounting plate and is located on the inlet side of the flat wire outlet; when the rotating shaft rotates to align the round wire outlet with the outlet limiting groove, the attitude limiting channel deviates from the outlet reference plane along with the flat wire adjustment mounting plate to avoid the outlet path of the round wire from the round wire outlet to the outlet limiting groove; the flat wire output by the servo tensioner passes through the flat wire guide wheel, the flat wire adjustment rod and the attitude limiting channel in sequence, and is then output from the flat wire outlet to the outlet limiting groove.

[0010] Furthermore, the round wire outlet and the flat wire outlet rotate synchronously with the rotating shaft; when the rotating shaft rotates to the round wire working position, the round wire outlet corresponds to the wire outlet limiting groove, and the flat wire outlet deviates from the wire outlet limiting groove; when the rotating shaft rotates to the flat wire working position, the flat wire outlet corresponds to the wire outlet limiting groove, and the round wire outlet deviates from the wire outlet limiting groove.

[0011] Furthermore, the support plate is provided with a clamping structure, which has a copper wire clamp located above the flying fork claw; the copper wire clamp is used to clamp a segment of round or flat wire, the flying fork spindle is used to drive the flying fork claw to rotate, and the copper wire clamp can rotate simultaneously with the flying fork claw, so that the round or flat wire entering the flying fork claw from the wire exiting limiting groove can be wound on the magnetic core in an α-winding manner.

[0012] Furthermore, the support plate is provided with a feeding module, which has a moving arm and a magnetic suction nozzle on the moving arm; the magnetic suction nozzle is used to pick up the magnetic core, and the moving arm is used to drive the magnetic suction nozzle to move the magnetic core to the winding station corresponding to the flying fork claw, so that the copper wire clamp and the flying fork claw can cooperate to wind the round or flat wire onto the magnetic core.

[0013] Furthermore, the carrier plate is also provided with a circulating flipping structure and a cutting structure. The cutting structure is located after the winding station of the flying fork spindle and is used to cut the wound lead wire. The circulating flipping structure is located after the cutting structure and is used to clamp the cut lead wire and fold the lead wire over the magnetic core.

[0014] Furthermore, when the rotating shaft rotates to the round wire working position, the round wire is wound around the round wire outlet, the outlet limiting groove and the flying fork claw to form a round wire winding product; when the rotating shaft rotates to the flat wire working position, the flat wire is wound around the flat wire outlet, the outlet limiting groove and the flying fork claw to form a flat wire winding product.

[0015] The beneficial effects of this invention are as follows: This application provides a universal winding machine for round and flat wires. Existing round and flat wire winding usually requires separate wire arrangement structures or different equipment. This invention sets the round wire adjustment mounting plate and the flat wire adjustment mounting plate on the same rotating shaft, and realizes the selection and switching of the round wire outlet and the flat wire outlet by rotating the rotating shaft relative to the extension plate. This allows both types of wires to correspond to the same wire outlet limiting groove and the same flying fork claw wire clamping area, reducing the workload of readjusting the entire wire arrangement mechanism or replacing the winding equipment when changing types. This application provides a universal winding machine for round and flat wires. The present invention uses a wire exit limiting groove to uniformly constrain the output position of the round wire exit or the flat wire exit, so that the round wire and the flat wire have a relatively consistent exit position before entering the flying fork claw. This helps to reduce the wire clamping deviation of the flying fork claw and reduces the problem that the exit reference of the round wire and the flat wire is easily inconsistent when only two independent wire nozzles are set in the existing equipment.

[0016] This application provides a universal winding machine for round and flat wires. Existing winding methods that rely solely on the rotation of the magnetic core or a single wire clamp end are inefficient. This invention uses copper wire clamps and flying fork claws to participate in the winding action simultaneously, enabling round or flat wires to be wound onto the magnetic core in an α-winding manner, thereby improving winding efficiency and facilitating subsequent processing of the lead wires by a cutting structure and a circulating wire-turning structure.

[0019] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0020] Example 1, as Figures 1 to 11 As shown, this embodiment provides a universal winding machine for both round and flat wires, including a frame 1, which supports the various functional modules of the winding machine. A support plate 2 is provided on the frame 1, which can serve as the mounting base for structures such as wire supply, wire switching, winding, cutting, and flipping. A wire roller 4 and a servo tensioner 5 are provided on the support plate 2. The wire roller 4 is used to install round or flat wire coils and supply wire to the subsequent winding station. The servo tensioner 5 is used to adjust the tension of the wire output from the wire roller 4, so that the wire has a relatively stable tension state before entering the subsequent round or flat wire adjustment path. Compared with the ordinary passive guide wire supply method, the servo tensioner 5 can adjust the tension according to the wire conveying state, reducing the problem of uneven winding caused by the wire being too loose or too tight during the winding process. A movable seat 6 is provided on the support plate 2, which is used to install the switching component; a switching mounting plate 10 is provided on the movable seat 6, and an extension plate 11 is provided on the switching mounting plate 10. The extension plate 11 extends to the winding area where the fly fork spindle 32 is located, so that the round wire outlet 16 or the flat wire outlet 21 can be switched to the position corresponding to the outlet limiting groove 31; a rotating shaft 12 is rotatably connected to the extension plate 11, and the rotating shaft 12 can rotate relative to the extension plate 11 around its own axis; the rotating shaft 12 is not only used as a normal support shaft, but also as a common switching shaft for the round wire adjustment mounting plate 13 and the flat wire adjustment mounting plate 17, which is used to drive the round wire adjustment mounting plate 13 and the flat wire adjustment mounting plate 17 to switch between the round wire working position and the flat wire working position; A round wire adjustment mounting plate 13 and a flat wire adjustment mounting plate 17 are provided on the rotating shaft 12. A round wire outlet 16 is formed on the round wire adjustment mounting plate 13, which is used to output the round wire to the subsequent fly fork clamping area. A flat wire outlet 21 is formed on the flat wire adjustment mounting plate 17, which is used to output the flat wire to the subsequent fly fork clamping area. Since both the round wire adjustment mounting plate 13 and the flat wire adjustment mounting plate 17 are mounted on the rotating shaft 12, when the rotating shaft 12 rotates relative to the extension plate 11, the round wire outlet 16 and the flat wire outlet 21 can change their spatial positions synchronously with the rotating shaft 12. In this way, in the round wire processing mode, the round wire outlet 16 is rotated to the wire exit position; in the flat wire processing mode, the flat wire outlet 21 is rotated to the same wire exit position, thereby avoiding clamping deviation caused by the use of independent wire exit references for the round wire and the flat wire.

[0021] like Figure 4 , Figure 7 and Figure 9 As shown, the rotating shaft 12 has a rectangular mounting section and a hollow cylindrical limiting section; the rectangular mounting section is used to install the round wire adjustment mounting plate 13 and the flat wire adjustment mounting plate 17; the rotating shaft 12 has a rectangular mounting section and a hollow cylindrical limiting section; the round wire adjustment mounting plate 13 and the flat wire adjustment mounting plate 17 are respectively provided with rectangular mounting holes that match the rectangular mounting section. During installation, the round wire adjustment mounting plate 13 and the flat wire adjustment mounting plate 17 are fitted onto the rectangular mounting section through the corresponding rectangular mounting holes, and the inner wall of the rectangular mounting holes is flush with the rectangular mounting section. The outer surfaces of the rectangular mounting section fit together, so that the round wire adjustment mounting plate 13, the flat wire adjustment mounting plate 17 and the rotating shaft 12 rotate synchronously. During installation, the round wire adjustment mounting plate 13 and the flat wire adjustment mounting plate 17 can be locked onto the rectangular mounting section by clamps or fastening screws to restrict their axial movement along the rotating shaft 12. The hollow cylindrical limiting section is used to cooperate with the moving rod 25 and form a guide groove 29; at the same time, it can reduce the weight of the end of the rotating shaft 12 and make the switching action of the rotating shaft 12 smoother.

[0022] like Figure 6 and Figure 7As shown, a mounting base 23 is fixedly mounted on the extension plate 11, and a limit ring 24 is provided on the mounting base 23; a movable rod 25 is movably mounted inside the mounting base 23, and the movable rod 25 is connected to a connecting plate 26. The connecting plate 26 is connected to a handle 27 via a connecting shaft 28; the handle 27 serves as a manually operated component or an externally driven connecting component, and can drive the connecting plate 26 to move via the connecting shaft 28. The connecting plate 26 further drives the movable rod 25 to move along the mounting base 23; the limit ring 24 constrains the movement direction of the movable rod 25, allowing the movable rod 25 to move linearly in the direction approaching or away from the rotating shaft 12, preventing the movable rod 25 from swaying during locking and releasing; a guide groove 29 is provided on the hollow cylindrical limit section of the rotating shaft 12, into which the movable rod 25 can extend. A guide groove 29 is provided on the hollow cylindrical limiting section of the rotating shaft 12. The guide groove 29 includes a round wire positioning section, a flat wire positioning section, and a transition guide section connecting the round wire positioning section and the flat wire positioning section. The round wire positioning section and the flat wire positioning section correspond to two positions of the rotating shaft 12, respectively, restricting the rotating shaft 12 to rotate circumferentially, so that the round wire outlet 16 is kept at the outlet position corresponding to the outlet limiting groove 31. At the corresponding exit station, the outlet center of the round wire outlet 16 or the outlet center of the flat wire outlet 21 is located in the same exit reference plane as the slot center of the exit limiting groove 31, and the exit direction of the round wire outlet 16 or the flat wire outlet 21 faces the entrance of the exit limiting groove 31. Due to the different wiring methods, the round wire outlet 16 and the flat wire outlet 21 have different offsets relative to the axis of the rotating shaft 12 to compensate for the height difference between the center of the round wire and the flat wire cross sections, so that the round wire and the flat wire are pulled out at the same position. Through the above structure, although the round wire and the flat wire go through different adjustment paths, they are unified to the same exit limiting groove 31 before entering the flying fork 33, thereby ensuring that the position of the flying fork 33 clamping the wire is relatively consistent and reducing the wire clamping deviation caused by the difference in wire cross sections. When the moving rod 25 extends into the flat wire positioning section, the end of the moving rod 25 engages with the two side groove walls of the flat wire positioning section, restricting the rotation shaft 12 from rotating circumferentially, so that the flat wire outlet 21 is kept at the outlet position corresponding to the outlet restriction groove 31. When it is necessary to switch working positions, the moving rod 25 is driven out of the current positioning section by the handle 27. One end of the moving rod 25 is provided with a protrusion that engages with the guide groove 29. When the moving rod 25 extends into or out of the guide groove 29, it can drive the rotation shaft 12 to rotate. The rotation shaft 12 can then rotate relative to the extension plate 11 to another working position. Then, the moving rod 25 extends into another positioning section to complete the locking. The transition guide section is a spiral guide groove, which guides the rotation shaft 12 to switch smoothly between two stable angular positions. When the moving rod 25 is in the round wire positioning section or the flat wire positioning section, the rotation position of the rotation shaft 12 is restricted, instead of continuing to be driven to rotate.

[0023] like Figure 4 As shown, the circular wire adjustment mounting plate 13 is equipped with a circular wire guide wheel 14 and a circular wire adjustment rod 15. The circular wire guide wheel 14 is located on the inlet side of the circular wire outlet 16 and is used to change or stabilize the direction of the circular wire before it enters the circular wire outlet 16. The circular wire adjustment rod 15 is located between the circular wire guide wheel 14 and the circular wire outlet 16 and is used to fine-tune the passing position of the circular wire so that the circular wire can enter the circular wire outlet 16 along a predetermined path. During operation, the circular wire output from the wire roller 4 and after the tension is adjusted by the servo tensioner 5, enters the circular wire path where the circular wire adjustment mounting plate 13 is located. After passing through the circular wire guide wheel 14 and the circular wire adjustment rod 15 in sequence, the circular wire is output from the circular wire outlet 16. Since the cross-sectional directionality of the circular wire is relatively weak, the circular wire guide wheel 14 and the circular wire adjustment rod 15 are mainly used to ensure the stability of the circular wire outlet position and outlet direction.

[0024] like Figure 5 As shown, the flat wire adjustment mounting plate 17 is provided with a flat wire guide wheel 18, a flat wire adjustment rod 19, a flat wire limiting plate 20, and a flat wire spacing adjustment rod 22; the flat wire guide wheel 18 is located on the inlet side of the flat wire outlet 21 and is used to guide the flat wire; the flat wire adjustment rod 19 is used to adjust the position of the flat wire before it enters the flat wire limiting plate 20; A flat wire limiting plate 20 is disposed between the flat wire guide wheel 18 and the flat wire outlet 21. The flat wire limiting plate 20 forms a posture-limiting channel for the flat wire to pass through. The width direction of this posture-limiting channel corresponds to the width direction of the flat wire, which is used to limit the flat wire from flipping or swaying during the passage, so that the flat wire maintains a relatively stable width direction before entering the flat wire outlet 21. The flat wire spacing adjustment rod 22 is connected to the flat wire limiting plate 20. The flat wire spacing adjustment rod 22 can be in the form of a threaded adjustment rod. By rotating the flat wire spacing adjustment rod 22, the flat wire limiting plate 20 is moved closer to or away from the flat wire passage path, thereby adjusting the limiting spacing of the posture-limiting channel, so that the posture-limiting channel can adapt to flat wires of different thicknesses or widths. During operation, the flat wire output from the wire roller 4 and whose tension is adjusted by the servo tensioner 5 enters the flat wire... The flat wire path of the adjustment mounting plate 17 is adjusted. The flat wire passes through the flat wire guide wheel 18, the flat wire adjustment rod 19 and the flat wire limiting plate 20 in sequence, and is output from the flat wire outlet 21. Since the flat wire limiting plate 20 is installed on the flat wire adjustment mounting plate 17, the flat wire limiting plate 20 rotates synchronously with the flat wire adjustment mounting plate 17. When the rotation shaft 12 is switched to the flat wire working position, the flat wire limiting plate 20 enters the outlet reference plane and is located on the inlet side of the flat wire outlet 21, which restricts the attitude of the flat wire wide face. When the rotation shaft 12 is switched to the round wire working position, the flat wire limiting plate 20 deviates from the outlet reference plane with the flat wire adjustment mounting plate 17, and avoids the round wire outlet path. When sharing the same outlet limiting groove 31, it can simultaneously take into account the flat wire anti-flipping, anti-swaying and round wire interference-free outlet.

[0025] like Figure 2 , Figure 3 and Figure 4 As shown, a fork spindle 32 is mounted on the bearing plate 2, and a fork claw 33 is mounted on the fork spindle 32. A positioning block 34 is mounted on the housing of the fork spindle 32, and a wire exit limiting groove 31 is mounted on the positioning block 34. The wire exit limiting groove 31 serves as a common wire exit reference for both round and flat wires before they enter the wire clamping area of ​​the fork claw 33. When the rotating shaft 12 rotates to the round wire working position, the round wire outlet 16 corresponds to the wire exit limiting groove 31, and the outlet center of the round wire outlet 16 and the groove center of the wire exit limiting groove 31 are at the same point. The reference plane is set, and the wire exit direction of the round wire exit port 16 is towards the entrance of the wire exit restriction groove 31. The flat wire exit port 21 is offset from the wire exit restriction groove 31. The round wire can be output through the round wire exit port 16 to the wire exit restriction groove 31 and enter the wire clamping area of ​​the fly fork claw 33. When the rotating shaft 12 rotates to the flat wire working position, the flat wire exit port 21 corresponds to the wire exit restriction groove 31, the round wire exit port 16 is offset from the wire exit restriction groove 31, and the flat wire can be output through the flat wire exit port 21 to the wire exit restriction groove 31 and enter the wire clamping area of ​​the fly fork claw 33.

[0026] like Figure 2 , Figure 3 and Figure 7 As shown, the support plate 2 is also provided with a clamping structure 7, which has a copper wire chuck 30 located above the flying fork claw 33. The copper wire chuck 30 is used to clamp the wire segment of round or flat wire, and the flying fork claw 33 is used to clamp or drive the wire segment entering through the wire exit restriction groove 31. The flying fork spindle 32 is used to drive the flying fork claw 33 to rotate, and the flying fork claw 33 can move up and down independently. When winding, the copper wire chuck 30 and the flying fork claw 33 participate in the rotation at the same time, so that the round or flat wire can be wound on the magnetic core in an α winding manner. The α winding method described in this application refers to the wire being output through the round wire outlet 16 or the flat wire outlet 21, and then entering the winding area from the bottom of the magnetic core through the wire exit limiting groove 31. The flying fork 33 drives the magnetic core to rotate, while the copper wire clamp 30 clamps the wire segment located above the magnetic core and moves around the same winding central axis, so that the wire forms a continuous winding path on the upper and lower sides of the magnetic core. When the magnetic core is located at the winding station corresponding to the flying fork 33, a magnetic core support position is formed at the winding station. The magnetic core support position is used to receive the magnetic core after the magnetic suction nozzle 36 releases the magnetic core and limit the magnetic core's offset during the winding process. Depending on the different coil specifications, the copper wire clamp 30 and the flying fork 33 can rotate simultaneously at a preset speed ratio.

[0027] In one embodiment, the rotational speed of the flying fork spindle 32 driving the flying fork claw 33 is greater than the rotational speed of the copper wire chuck 30. Preferably, the rotational speed of the flying fork claw 33 is twice the rotational speed of the copper wire chuck 30. With this rotational speed ratio, the flying fork claw 33 can improve the winding efficiency of the wire relative to the magnetic core while the copper wire chuck 30 participates in the winding simultaneously. The flying fork claw 33 can also be adjusted in the vertical direction according to the coil arrangement needs, so that the winding forms a more orderly arrangement on the magnetic core.

[0028] like Figure 10 As shown, a feeding module 9 is provided on the support plate 2. The feeding module 9 has a moving arm 35 and a magnetic suction nozzle 36 provided on the moving arm 35. The magnetic suction nozzle 36 is used to pick up the magnetic core, and the moving arm 35 is used to drive the magnetic suction nozzle 36 to move the magnetic core to the winding station corresponding to the flying fork claw 33. The magnetic suction nozzle 36 can be used in conjunction with a vibratory feeder or other magnetic core feeding mechanism so that the magnetic core can be picked up and transferred to the winding area in sequence. After the magnetic core arrives at the winding station, the round wire or flat wire is selected by the switching component to enter the flying fork claw 33 through the corresponding wire exit path. The copper wire clamp 30 and the flying fork claw 33 cooperate to wind the round wire or flat wire onto the magnetic core.

[0029] like Figure 8 As shown, the support plate 2 is also provided with a circulating wire-flipping structure 3 and a cutting structure 8. The cutting structure 8 is located after the winding station of the flying fork spindle 32 and is used to cut the wound lead wire. The circulating wire-flipping structure 3 is located after the cutting structure 8 and is used to clamp the cut lead wire and fold the lead wire above the magnetic core. Specifically, after the winding is completed, the cutting structure 8 cuts off the excess lead wire, and the circulating wire-flipping structure 3 clamps the cut lead wire and folds the lead wire from a horizontal state to above the magnetic core for subsequent forming, cutting, or welding. The circulating wire-flipping structure 3 and the cutting structure 8 can be implemented using existing clamping, rotating, or cutting mechanisms, as long as they can complete the lead wire cutting and folding. The support plate 2 is also equipped with a circulating flipping structure 3 and a cutting structure 8. The cutting structure 8 is located after the winding station of the flying fork spindle 32 and is used to cut the wound lead wire. The circulating flipping structure 3 is located after the cutting structure 8 and is used to clamp the cut lead wire and fold it over the magnetic core. After the winding is completed, the circulating flipping structure 3 first clamps the two lead wires that are close to the magnetic core and need to be retained. Then the cutting structure 8 cuts off the excess wire segments located outside the clamping position of the circulating flipping structure 3. The cut excess wire segments are removed as waste or wire segments to be processed later. The two retained lead wires close to the magnetic core are still clamped by the circulating flipping structure 3. Therefore, the retained lead wires are not in a completely free state after cutting. Subsequently, the circulating flipping structure 3 continues to clamp the two retained lead wires and folds them from a horizontal state to the top of the magnetic core for subsequent forming, cutting or welding processing.

[0030] like Figure 11As shown, when the rotating shaft 12 is in the round wire working position, the round wire is wound through the round wire outlet 16, the wire outlet limiting groove 31 and the flying fork claw 33 to form a round wire winding product 37; when the rotating shaft 12 is in the flat wire working position, the flat wire is wound through the flat wire outlet 21, the wire outlet limiting groove 31 and the flying fork claw 33 to form a flat wire winding product 38; thus, the same winding machine can be compatible with both round wire and flat wire, and both round wire and flat wire enter the clamping area of ​​the flying fork claw 33 through the same wire outlet limiting groove 31, which helps to reduce the workload of changing and adjusting and improve the winding consistency.
