Description

Technical Field

[0001] The present invention relates to the technical field of axial flux motors, and in particular to a winding device and a winding method for a winding skeleton of an axial flux motor. Background Art

[0002] The magnetic flux direction of the axial flux motor is axial, which has the advantages of higher efficiency and better heat dissipation. In the coil winding production process of the axial flux motor, in order to improve the coil winding production efficiency, the continuous winding technology of the coil is developed, that is, a single wire is continuously wound into multiple coils on multiple winding skeletons to achieve one-time winding production of the coil winding.

[0003] In the related art, for the winding of single-layer coils on the same winding skeleton, after the wire is wound from the lower end of the winding skeleton to the upper end of the winding skeleton along the axial direction of the winding skeleton to complete the winding of the single-layer coil, the wire needs to be moved to the lower end of another winding skeleton to continue the winding of the single-layer coil. There will be an inclined bridge wire between two adjacent winding skeletons. In the subsequent coil winding process, the gap between two adjacent single-layer coils in the coil winding is smaller than the diameter of the wire slot, and the gap between two adjacent single-layer coils cannot accommodate the bridge wire. If the bridge wire is forcibly set between two adjacent single-layer coils, the spacing between the two adjacent single-layer coils will increase, and the slot full rate of the coil winding will be reduced. In the existing scheme, in order to solve the problem of inclined bridge wires in two adjacent single-layer coils, a stepped winding device for single-layer coils is designed, that is, multiple winding skeletons are arranged in a circle, and the vertical heights of the multiple winding skeletons decrease or increase successively, so that the bridge wire between two adjacent single-layer coils is arranged horizontally. However, the structure of the above-mentioned stepped winding equipment is complex and occupies a large space. In addition, since the winding directions of two adjacent odd-layer coils are opposite, in the coil winding of the existing scheme, whether it is an inclined bridge wire or a horizontal bridge wire, the bridge wire is set within the range directly opposite to the two adjacent odd-layer coils. When the subsequent coil winding and stator core are embedded, the staff needs to manually adjust the position of the bridge wire and move the bridge wire from the range directly opposite to the two adjacent odd-layer coils to the outside of the odd-layer coil. Manual adjustment of the bridge wire by the staff not only greatly reduces the subsequent embedding efficiency of the coil winding, but also has high labor intensity.

[0004] Therefore, it is urgent to invent a winding device and a winding method for an axial flux motor winding skeleton to solve the above problems. Summary of the invention

[0005] The object of the present invention is to provide a winding device and a winding method for an axial flux motor winding skeleton, so as to realize continuous winding of multiple winding skeletons in which wires are arranged in a straight line in the same plane, and to tighten the bridge wire to improve the wire embedding efficiency of subsequent coil windings and stator cores.

[0068] Embodiment 1

[0069] Continuously winding a single wire into multiple coils on multiple winding skeletons and connecting multiple coils in sequence is called continuous winding of the coil. In the related art, for the winding of single-layer coils on the same winding skeleton, after the wire is wound along the axial direction of the winding skeleton from the lower end of the winding skeleton to the upper end of the winding skeleton to complete the winding of the single-layer coil, the wire needs to be moved to the lower end of another winding skeleton to continue the winding of the single-layer coil. There will be an inclined bridge wire between two adjacent winding skeletons. In the subsequent coil winding process, the gap between two adjacent single-layer coils in the coil winding is smaller than the diameter of the wire slot, and the gap between two adjacent single-layer coils cannot accommodate the bridge wire. If the bridge wire is forcibly set between two adjacent single-layer coils, the distance between the two adjacent single-layer coils will increase, reducing the slot fill rate of the coil winding. In the existing scheme, in order to solve the problem of inclined bridge wires in two adjacent odd-layer coils, a step-type winding device for the coils is designed, that is, multiple winding skeletons are arranged in a circle, and the vertical heights of the multiple winding skeletons are successively reduced or increased, so that the bridge wires between the two adjacent coils are arranged horizontally. However, the structure of the above-mentioned step-type winding device is complex and occupies a large space. In addition, since the winding directions of the two adjacent odd-layer coils are opposite, in the coil winding of the existing scheme, whether it is an inclined bridge wire or a horizontal bridge wire, the bridge wire is set within the range directly facing the two adjacent odd-layer coils. When the subsequent coil winding and the stator core are embedded, the staff needs to manually adjust the position of the bridge wire and move the bridge wire from the range directly facing the two adjacent odd-layer coils to the outside of the odd-layer coil. The manual adjustment of the bridge wire by the staff not only greatly reduces the subsequent embedding efficiency of the coil winding, but also has high labor intensity.

[0070] In order to solve the above problems, Figure 1 to Figure 6 As shown, this embodiment provides a winding device for an axial flux motor winding skeleton. The winding device for the axial flux motor winding skeleton includes a clamping device 100 and a winding device 200, wherein a plurality of winding skeleton mounting positions are arranged at intervals along a preset direction on the mounting seat 140, there are a plurality of clamping mechanisms 110, each winding skeleton mounting position corresponds to at least one clamping mechanism 110, the clamping mechanism 110 is used to clamp and fix the winding skeleton 2000 on the mounting seat 140, there is at least one bridge wire winding needle 120, the bridge wire winding needle 120 is arranged between two adjacent winding skeleton mounting positions, the bridge wire winding needle 120 is used to tighten the bridge wire of the winding on the winding skeleton 2000 at two adjacent winding skeleton mounting positions and control the length of the bridge wire, and the winding device 200 can sequentially wind the wire on the winding skeleton 2000 and the bridge wire winding needle 120 along the preset direction.

[0071] The winding device of the winding skeleton of the axial flux motor is provided with a plurality of winding skeleton installation positions spaced along a preset direction on the installation seat 140, so that each winding skeleton installation position corresponds to at least one clamping mechanism 110, and the winding skeleton 2000 is clamped and fixed by the clamping mechanism 110, thereby achieving the clamping and fixing of the winding skeleton 2000 along the preset direction, and a bridge wire winding needle 120 is provided between two adjacent winding skeleton installation positions, and the winding skeleton at the two adjacent winding skeleton installation positions is tightened by the bridge wire winding needle 120. The bridge wire of the winding on the frame 2000 is arranged, and the length of the bridge wire is controlled. In combination with the winding device 200, the wire is wound on the winding frame 2000 and the bridge wire winding needle 120 in sequence along the preset direction, thereby realizing continuous winding on the winding frame 2000 in which the wire is arranged in sequence along the preset direction in the same plane, and the bridge wire between the windings on two adjacent winding frames 2000 can be tightened, which is convenient for the subsequent wiring of the bridge wire, thereby improving the subsequent wire embedding efficiency of the coil winding and the stator core.

[0072] It should be noted that, in this embodiment, the preset direction is the left-right direction, each winding frame installation position is set corresponding to a set of clamping mechanisms 110, each set of clamping mechanisms 110 can clamp and fix a winding frame 2000 in the winding frame installation position, and a bridge wire winding needle 120 is set between each two adjacent winding frame installation positions. In other embodiments, the specific direction of the preset direction, the number of clamping mechanisms 110 corresponding to each winding frame installation position, and the specific number of bridge wire winding needles 120 can also be adjusted according to actual needs, and this embodiment does not make specific limitations.

[0073] In addition, the winding equipment for the axial flux motor winding frame provided in this embodiment is not only applicable to the continuous winding of an odd number of layers of coils on the same winding frame 2000 , but also applicable to the continuous winding of an even number of layers of coils on the same winding frame 2000 .

[0074] In this embodiment, the bridge wire winding needle 120 is located outside the winding frame installation position along the preset direction, and the bridge wire winding needle 120 can move in a direction perpendicular to the preset direction. By setting the bridge wire winding needle 120 outside the winding frame installation position along the preset direction, and enabling the bridge wire winding needle 120 to move in a direction perpendicular to the preset direction, the bridge wire can be tightened outside the two adjacent winding frames 2000 along the preset direction, without the need to take the bridge wire out of the gap between the two adjacent winding frames 2000 along the preset direction, further improving the efficiency of the bridge wire management. Moreover, by enabling the bridge wire winding needle 120 to move in a direction perpendicular to the preset direction, the bridge wire winding needle 120 can be driven to extend outward relative to the winding frame installation position according to actual needs, thereby adjusting the length of the bridge wire wound on the bridge wire winding needle 120, thereby achieving the effect of changing the length of the bridge wire on the two adjacent winding frames 2000. It should be noted that, in the present embodiment, since the preset direction is the left-right direction, the bridge thread winding needle 120 can be extended and retracted along the front-back direction.

[0075] As an optional solution, the clamping device 100 also includes a telescopic mechanism 130, wherein the telescopic mechanism 130 includes a first driving member 131, the first driving member 131 is installed at the mounting seat 140, the first driving member 131 is connected to the bridge wire winding needle 120, and the telescopic mechanism 130 can drive the bridge wire winding needle 120 to move in a direction perpendicular to the preset direction. By connecting the bridge wire winding needle 120 to the output end of the first driving member 131 in the telescopic mechanism 130, the first driving member 131 drives the bridge wire winding needle 120 to telescope in a direction perpendicular to the preset direction, which can not only adjust the length of the bridge wire, but also drive the bridge wire winding needle 120 to extend out of the winding frame installation position when the wire needs to be wound on the bridge wire winding needle 120, and retract the bridge wire winding needle 120 to the winding frame installation position when winding is not required, which can improve the protection of the bridge wire winding needle 120. It should be noted that in this embodiment, the first driving member 131 is a linear cylinder. The linear cylinder has a simple structure, is responsive, and is easy to assemble and disassemble. In other embodiments, the first driving member 131 may also be a linear motor, a rotary motor and a lead screw nut structure or other linear driving structures, which are not specifically limited in this embodiment.

[0076] To further improve the protection of the bridge wire winding needle 120, as Figure 3 and Figure 4As shown, the telescopic mechanism 130 also includes an elastic reset structure, which includes an abutment 132, a stopper 133 and an elastic member 134. The bridge wire winding needle 120 is connected to the abutment 132, and one axial end of the abutment 132 is movably connected to the output end of the first driving member 131 in a direction perpendicular to a preset direction. The other axial end of the abutment 132 is configured to abut against the clamping mechanism 110, and the stopper 133 is fixed to the outer periphery of the abutment 132. The elastic member 134 is sleeved on the outer periphery of the abutment 132, and one end of the elastic member 134 abuts against the stopper 133, and the other end of the elastic member 134 abuts against the mounting seat 140.

[0077] When the first driving member 131 drives the bridge wire winding needle 120 to extend out of the winding frame installation position, the output end of the first driving member 131 first moves relative to the abutment member 132 toward the winding frame installation position, and then the output end of the first driving member 131 is relatively fixed to the abutment member 132, and then the first driving member 131 continues to drive the abutment member 132 to move toward the winding frame installation position, thereby driving the bridge wire winding needle 120 connected to the abutment member 132 to move toward the winding frame installation position. The elastic member 134 is compressed when the bridge wire winding needle 120 extending outward from the winding frame mounting position needs to be retracted, and the first driving member 131 stops working, and the elastic member 134 is reset under the action of its own elastic force, thereby driving the stopper 133, the abutment 132 and the bridge wire winding needle 120 to move in the opposite direction, so that the bridge wire winding needle 120 is retracted from the outside of the winding frame mounting position to the winding frame mounting position.

[0078] It should be noted that, in the present embodiment, the abutment 132 is cylindrical, and a movable section 1321 is provided on the abutment 132, the diameter of the movable section 1321 is smaller than the diameter of the abutment 132, and the movable section 1321 is movably connected to the output end of the first driving member 131. The elastic member 134 is a spring, and the spring structure is simple and compact. A through hole extending perpendicular to a preset direction is provided on the mounting seat 140, and a portion of the bridge wire winding needle 120 is located in the through hole, and a mounting member 121 is provided on the bridge wire winding needle 120, and the mounting member 121 is fixed to the abutment 132, so as to achieve the effect that the abutment 132 drives the bridge wire winding needle 120 to extend or retract the winding skeleton mounting position.

[0079] like Figure 2 , Figure 4 and Figure 5As shown, the clamping mechanism 110 includes a positioning member 111 and a pressing member 112, wherein the positioning member 111 is fixed on the mounting seat 140, the winding skeleton 2000 is placed on the mounting seat 140 along its axial direction, the positioning member 111 extends upward into the axial through hole of the winding skeleton 2000, the pressing member 112 includes a pressing portion 1122 and a tensioning portion 1121 connected to each other, the tensioning portion 1121 can move in the up and down directions so that the tensioning portion 1121 extends from one end of the winding skeleton 2000 axially away from the mounting seat 140 into the axial through hole and jointly supports and fixes the winding skeleton with the positioning member 111, the tensioning portion 1121 is provided with a positioning groove 11211, the abutment 132 is plugged and positioned with the positioning groove 11211, so that the pressing portion 1122 presses the winding skeleton 2000 axially along the winding skeleton 2000 and fixes it on the mounting seat 140. By splitting the clamping mechanism 110 into a positioning piece 111 fixed on the mounting seat 140 and a movably arranged pressing piece 112, the tensioning portion 1121 of the pressing piece 112 is extended into the axial through hole of the winding skeleton 2000, and together with the positioning piece 111, the winding skeleton 2000 is supported and fixed to the radial direction, and the winding skeleton 2000 is positioned and fixed. By setting a positioning groove 11211 on the tensioning portion 1121, the abutment 132 is inserted and positioned with the positioning groove 11211, and the pressing portion 1122 on the pressing piece 112 can press the winding skeleton 2000 onto the mounting seat 140, so as to achieve the axial positioning and fixation of the winding skeleton 2000, so as to stably clamp and fix the winding skeleton 2000 on the mounting seat 140.

[0080] It should be noted that, in this embodiment, a first guide slope 112111 is provided on the side wall of the positioning groove 11211 which is parallel to the moving direction of the abutment 132. The first guide slope 112111 extends from the outside to the inside and is inclined toward the direction close to the pressing portion 1122. When the abutment 132 is docked with the positioning groove 11211, the abutment 132 can drive the pressing piece 112 to move downward under the guiding action of the first guide slope 112111, so as to further improve the axial positioning effect of the pressing piece 112 on the winding skeleton 2000.

[0081] As an alternative, Figure 7 As shown, the clamping device 100 further includes a picking mechanism 150, wherein the picking mechanism 150 is mounted on the mounting seat 140, and the picking mechanism 150 can transport the pressing piece 112 from the outside to the positioning piece 111, and remove the pressing piece 112 from the positioning piece 111. By setting the picking mechanism 150 to transport the pressing piece 112 from the outside to the positioning piece 111, and remove the pressing piece 112 from the positioning piece 111, the automatic clamping of the pressing piece 112 and the positioning piece 111 to the winding frame 2000 can be achieved.

[0082] Specifically, the picking mechanism 150 includes a second driving member 151, a picking hook 152, a bracket 153 and a third driving member 154, wherein the axial through hole of the winding skeleton 2000 extends in the up-down direction, the upper end surface of the pressing member 112 is provided with a first docking hole 11221 and a second docking hole 11222 which are in conduction with each other, the first docking hole 11221 is located at the inner end of the second docking hole 11222, the inner diameter of the first docking hole 11221 along the front-to-back direction is greater than the inner diameter of the second docking hole 11222 along the front-to-back direction, the bracket 153 is mounted on the frame 300, the second driving member 151 is mounted on the bracket 153, the picking hook 152 and the second driving member 154 are connected to each other, and the first docking hole 11221 is located at the inner end of the second docking hole 11222, and the inner diameter of the first docking hole 11221 along the front-to-back direction is greater than the inner diameter of the second docking hole 11222 along the front-to-back direction. The output end of the moving member 151 is connected so that the picking hook 152 is located above the positioning member 111, and the second driving member 151 drives the pressing member 112 to move in the up and down directions. The size of the picking hook 152 is smaller than the size of the second docking hole 11222, so that the picking hook 152 can extend into the second docking hole 11222 and be located in the first docking hole 11221. The third driving member 154 is installed on the frame 300, and the mounting seat 140 is connected to the output end of the third driving member 154. The third driving member 154 can drive the mounting seat 140 to move in the front-to-back direction, so that the hook portion of the picking hook 152 extends into the first docking hole 11221 in the front-to-back direction.

[0083] When it is necessary to pick up the pressing piece 112 that is docked with the positioning piece 111, the second driving piece 151 drives the picking hook 152 to move downward until the picking hook 152 extends upward into the first docking hole 11221, and then the third driving piece 154 drives the mounting seat 140 to move along the front-to-back direction, so that the hook portion of the picking hook 152 extends along the front-to-back direction into the area of ​​the first docking hole 11221 that is not connected to the second docking hole 11222 along the upper and lower directions. Finally, the second driving piece 151 drives the picking hook 152 to move upward, and the picking hook 152 can abut against the upper end surface of the area of ​​the first docking hole 11221 that is not connected to the second docking hole 11222 along the upper and lower directions, thereby driving the pressing piece 112 to move upward, thereby achieving the effect of picking up and driving the pressing piece 112 to move.

[0084] In addition, in order to improve the driving effect of the second driving member 151 on the picking hook 152 in the up-down direction, a first guide rail 1531 extending in the up-down direction is provided on the bracket 153, and a first guide slider 1521 is provided on the picking hook 152. The first guide slider 1521 is slidably matched with the first guide rail 1531 to provide guidance for the movement of the picking hook 152 when the second driving member 151 drives the picking hook 152 to move in the up-down direction relative to the bracket 153. Similarly, a second guide rail extending in the front-to-back direction can be provided on the frame 300, and a second guide slider slidably matched with the second guide rail can be provided on the mounting seat 140 to provide guidance for the movement of the mounting seat 140 in the front-to-back direction.

[0085] As an optional solution, the clamping device 100 further includes an ejection mechanism 160, wherein the ejection mechanism 160 is mounted on the mounting seat 140, and the ejection mechanism 160 can axially eject the winding skeleton 2000 from the positioning member 111 when the pressing member 112 is not clamped to fix the winding skeleton 2000, so as to further improve the efficiency of taking out the winding skeleton 2000, thereby improving the subsequent transportation and wire embedding efficiency of the winding skeleton 2000. It should be noted that in this embodiment, the ejection mechanism 160 is a lifting cylinder, which drives the winding skeleton 2000 to move upward, and the specific structure and working principle of the lifting cylinder belong to the prior art, which will not be described in detail here.

[0086] To further understand the specific structure of the clamping device 100 provided in this embodiment, Figure 8 to Figure 17 The specific clamping steps of the clamping device 100 are described as follows:

[0087] (1) The third driving member 154 drives the mounting seat 140 to move backward, so that the positioning member 111 and the pressing member 112 on the picking hook 152 are arranged in a staggered manner in the vertical direction;

[0088] (2) Place the winding skeletons 2000 on the periphery of the positioning members 111;

[0089] (3) The third driving member 154 drives the mounting seat 140 to move forward, so that the positioning member 111 is arranged correspondingly with the pressing member 112 on the picking hook 152;

[0090] (4) The second driving member 151 drives the picking hook 152 to move downward until the pressing member 112 and the positioning member 111 jointly position and fix the winding frame 2000 along the radial direction of the winding frame 2000;

[0091] (5) The third driving member 154 drives the mounting seat 140 to move backward, so that the hook portion of the picking hook 152 is moved away from the area of ​​the first docking hole 11221 that is not connected to the second docking hole 11222 along the vertical direction;

[0092] (6) The second driving member 151 drives the picking hook 152 to move out of the pressing member 112 . Meanwhile, the first driving member 131 drives the abutting member 132 to be inserted and positioned with the positioning groove 11211 in the pressing member 112 .

[0093] As an alternative, Figure 1As shown, the winding device 200 provided in this embodiment includes a winding nozzle 210, a wire clamping and cutting mechanism 230, and a first driving mechanism 220, wherein the winding nozzle 210 is connected to the feed roll, the winding nozzle 210 can convey wire, the wire clamping and cutting mechanism 230 is used to clamp and fix the wire conveyed by the winding nozzle 210 or cut the wire conveyed by the winding nozzle 210, and the winding nozzle 210 is connected to the first driving mechanism 220, and the first driving mechanism 220 can drive the winding nozzle 210 to move arbitrarily in space. By setting the first driving mechanism 220 to drive the winding nozzle 210 to move arbitrarily in space, combined with the clamping and fixing of the wire by the wire clamping and cutting mechanism 230, the effect of the winding nozzle 210 winding the wire on the winding skeleton 2000 can be achieved.

[0094] It should be noted that, in the present embodiment, a wire starting and binding needle and a wire taking-up binding needle are provided on the mounting seat 140, and the wire starting and binding needle and the wire taking-up binding needle are respectively provided at two ends along a preset direction in a multi-group clamping mechanism 110 arranged in sequence along a preset direction. When winding is required on the winding skeleton 2000, the winding nozzle 210 is first moved to the wire clamping and cutting mechanism 230 under the drive of the first driving mechanism 220, and the wire clamping and cutting mechanism 230 first clamps and fixes the wire delivered by the winding nozzle 210, and then the first driving mechanism 220 drives the winding nozzle 210 to move to the wire starting and binding needle, and the first driving mechanism 220 drives the winding nozzle 210 to wind the wire around the wire starting and binding needle, and then the wire clamping and cutting mechanism 230 loosens the wire, and the first driving mechanism 220 drives the winding nozzle 210 to move to the wire starting and binding needle. 10 moves to the winding frame 2000 adjacent to the wire starting and binding needle along the preset direction, and the first driving mechanism 220 drives the winding nozzle 210. Now the first driving mechanism 220 drives the winding nozzle 210 to move upward in a clockwise spiral relative to the winding frame 2000 to complete the winding of a single winding frame 2000, and then the first driving mechanism 220 drives the winding nozzle 210 to move to the bridge wire winding needle 120 adjacent to the winding frame 2000 that has completed the winding along the preset direction, and the wire delivered by the winding nozzle 210 is wound on The first driving mechanism 220 then drives the winding nozzle 210 to move to the winding frame 2000 adjacent to the winding bridge wire winding needle 120 along the preset direction, and moves the winding nozzle 210 upward in a counterclockwise spiral relative to the winding frame 2000 to complete the winding of the second winding frame 2000. There is an external bridge wire between the first winding frame 2000 and the second winding frame 2000, and the first winding frame 2000 and the second winding frame 2000 are connected. The winding direction of the wire is opposite, and so on, to complete the continuous winding of the entire winding skeleton 2000 clamped and fixed on the mounting seat 140, and then the first driving mechanism 220 drives the winding nozzle 210 to move to the wire taking-up and binding needle, and drives the winding nozzle 210 to wind the wire around the wire taking-up and binding needle, and finally the first driving mechanism 220 drives the winding nozzle 210 to move to the wire clamping and cutting mechanism 230, and the wire clamping and cutting mechanism 230 cuts the wire and clamps the wire delivered by the fixed winding nozzle 210 to complete the continuous winding of the coil winding.

[0095] The specific structure and working principle of the winding nozzle 210 and the wire clamping and cutting mechanism 230 are all existing technologies, and the first driving mechanism 220 can be an existing three-axis driving mechanism. To ensure the simplicity of the text, the specific structure of the winding nozzle 210, the first driving mechanism 220 and the wire clamping and cutting mechanism 230 will not be repeated here.

[0096] As an optional solution, the winding device 200 also includes a second driving mechanism 240, which is connected to the mounting seat 140 in the clamping device 100, and the second driving mechanism 240 can drive the mounting seat 140 and the winding skeleton 2000 clamped and fixed on the mounting seat 140 to move arbitrarily in space. By connecting the mounting seat 140 with the second driving mechanism 240, the second driving mechanism 240 drives the mounting seat 140 and the winding skeleton 2000 fixed on the mounting seat 140 to move arbitrarily in space, and combined with the first driving mechanism 220 driving the winding nozzle 210 to move arbitrarily in space, the winding nozzle 210 and the winding skeleton 2000 cooperate with each other to move for winding, and further improve the winding efficiency of the wire.

[0097] It is understandable that the second driving mechanism 240 may be an existing three-axis driving mechanism, and for the sake of brevity, it will not be described in detail here. Figure 1 and Figure 7 As shown, due to the large structure of the mounting seat 140, the space required to drive the mounting seat 140 to move arbitrarily in the space is large. In order to improve the structural compactness of the winding device for the magnetic flux motor winding skeleton, the second driving mechanism 240 only includes left and right driving modules that can drive the mounting seat 140 to move in the left and right directions, and the third driving member 154 drives the mounting seat 140 to move in the front-to-back direction, and the mounting seat 140 does not move in the up-down direction. During the actual winding operation, only the first driving mechanism 220 drives the winding nozzle 210 to move arbitrarily in the space.

[0098] In addition, the winding device 200 provided in this embodiment further includes a tensioning mechanism 250, wherein the tensioning mechanism 250 is arranged between the winding nozzle 210 and the feed roll, and the tensioning mechanism 250 is configured to tension the wire. By arranging the tensioning mechanism 250 between the winding nozzle 210 and the feed roll, the wire delivered to the winding nozzle 210 is tensioned by the tensioning mechanism 250, so that the stable delivery of the wire on the feed roll and the subsequent winding effect of the wire can be ensured. The specific structure and working principle of the tensioning mechanism 250 belong to the prior art and will not be described in detail here.
