Description

Technical Field

[0001] The present invention relates to the technical field of coil processing, and in particular, to a wire winding device and a wire winding system. Background Art

[0002] A coil is a core component of the electromagnetic part of a motor. After passing through an electric current, the coil generates a magnetic field, which interacts with the magnetic field generated by a permanent magnet or an electromagnet in the motor to generate a torque, thereby driving the operation of the motor.

[0003] In a motor, the winding quality of the coil directly affects the performance and efficiency of the motor. A tight and uniform winding can improve the concentration of the magnetic field, reduce energy consumption, and is beneficial to extending the service life of the motor. The coil is usually wound by an insulated wire, and the methods of manual winding or machine winding can be adopted. However, compared with manual winding, machine winding can better improve the precision and efficiency of winding the coil, thereby ensuring the quality stability of the coil.

[0004] However, the existing machine winding has uneven winding, for example, the winding is unevenly distributed on the bobbin, resulting in wire pressing, uneven density, and even wire arrangement disorder. This not only wastes the space of the wire groove, but also may cause the risk of inter-turn short circuit, which not only reduces the product yield of stator winding, but also reduces the service life of the motor. Summary of the Invention

[0005] In view of this, in response to the above technical problems, the present application provides a wire winding device and a wire winding system, wherein the wire winding system includes the wire winding device.

[0006] In a first aspect of an embodiment of the present application, a wire winding device is provided. The wire winding device includes a wire winding mechanism and a wire feeding mechanism. The wire winding mechanism includes a driving wheel set, a movable member, a first transmission component, a second transmission component, and a conveying wheel set. The first transmission component and the second transmission component are arranged on the movable member to move relative to the driving wheel set and the conveying wheel set along with the movable member, and have a first position and a second position relative to the driving wheel set. When the movable member is located at the first position, the first transmission component is connected between the driving wheel set and the conveying wheel set, so that the conveying wheel set rotates in a first rotation direction; when the movable member is located at the second position, the second transmission component is connected between the driving wheel set and the conveying wheel set, so that the conveying wheel set rotates in a second rotation direction; the wire feeding mechanism includes a guiding screw rod and a wire feeding component. The guiding screw rod is guidingly connected to the wire feeding component, and the rotation of the conveying wheel set drives the guiding screw rod to rotate, so as to drive the wire feeding component to reciprocate in a first direction.

[0007] In summary, the present application provides multiple wheel sets and multiple component structures, enabling the movement of the winding component. As a result, winding operations can be performed at different positions of the core, and only a single power source is required, eliminating the need to set up multiple power sources. Additionally, the present application also provides a movable member to switch the connection states of the first transmission component and the second transmission component with the drive wheel set and the conveyor wheel set, thereby correspondingly adjusting the movement direction of the winding component. This reduces the operation step of resetting the winding component after a single winding operation is completed, not only saving the working time of the winding operation and improving the efficiency of the winding operation, but also reducing manual intervention to a certain extent, further reducing the interference to the structure of the winding device caused by manual intervention, and maintaining the structural stability of the winding device to a certain extent.

[0008] In a second aspect of the embodiments of the present application, a winding system is provided, which includes the winding device mentioned in the first aspect of the embodiments of the present application.

[0009] Among them, the beneficial effects of the above second aspect can be referred to the analysis of the beneficial effects in the first aspect and its various implementation manners, and will not be repeated here. BRIEF DESCRIPTION OF THE DRAWINGS

[0028] In order to make the objectives, technical solutions and advantages of the embodiments of the present application clearer, the technical solutions of the embodiments of the present application will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present application. Obviously, the described embodiments are only a part of the embodiments of the present application, rather than all of the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments in the present application without creative efforts shall fall within the protection scope of the present application.

[0029] Unless otherwise defined, technical or scientific terms used herein shall have the ordinary meanings as understood by those of ordinary skill in the art to which this application belongs.

[0030] Reference herein to "embodiments" means that a particular feature, structure, or characteristic described in connection with the embodiments can be included in at least one embodiment of the present application. The phrase appears in various places in the specification and does not necessarily refer to the same embodiment, nor is it an independent or alternative embodiment mutually exclusive with other embodiments. Those skilled in the art will explicitly and implicitly understand that the embodiments described herein can be combined with other embodiments.

[0031] Motor equipment is one of the core equipment indispensable in modern industry and daily life. As a device for converting electrical energy and mechanical energy, it plays a key role in energy conversion and power transmission. Motor equipment is widely used in many fields, such as various mechanical equipment in industrial production, the traction system of transportation vehicles, and the core power source of household appliances, greatly improving production efficiency and quality of life.

[0032] In motor equipment, the coil is the core component of the electromagnetic part of the motor equipment. The quality of the coil formed after winding is related to the service life and operating performance of the motor equipment. Therefore, how to improve the winding effect of the coil is a research direction that cannot be ignored in the production of motor equipment.

[0033] Please first refer to Figure 1 , this application provides a winding system 1000. The winding system 1000 includes a winding device 1, and the winding device 1 is used for winding coils to improve the winding quality and effect of the coils, thereby improving the service performance and service life of the motor 300 equipment.

[0034] Next, in conjunction with Figures 2 to 14 , the structure and usage of the winding device 1 in the solution of this application will be described in detail. Among them, the length direction L, width direction W, and height direction H in each drawing are uniformly maintained accordingly, and the reference targets of the length direction L, width direction W, and height direction H in each drawing are all the winding device 1; Figures 6 to 8 The first turning R1 and the second turning R2 in

[0035] Please refer to Figures 2 to 5 first. The winding device 1 includes a winding mechanism 100 and a wire feeding mechanism 200. Specifically, the winding mechanism 100 includes a driving wheel set 110, a movable member 120, a first transmission component 130, a second transmission component 140, and a conveying wheel set 150. Specifically, the driving wheel set 110 is used to provide the driving force required for the operation of the winding device 1, and the first transmission component 130, the second transmission component 140, and the conveying wheel set 150 are used to transmit the driving force provided by the driving wheel set 110 so that other mechanisms or components can operate.

[0036] Please further refer to Figure 6 and Figure 7 ( Figure 6 and Figure 7 in which the movable member 120 and the regulation frame 170 are hidden). The first transmission component 130 and the second transmission component 140 are arranged on the movable member 120 to move relative to the driving wheel set 110 and the conveying wheel set 150 along with the movable member 120, and have a first position (such as Figure 6 ) and a second position (such as Figure 7 ) relative to the driving wheel set 110. When the movable member 120 is in the first position, the first transmission component 130 is connected between the driving wheel set 110 and the conveying wheel set 150, causing the conveying wheel set 150 to rotate around the first rotation direction R1; when the movable member 120 is in the second position, the second transmission component 140 is connected between the driving wheel set 110 and the conveying wheel set 150, causing the conveying wheel set 150 to rotate around the second rotation direction R2. That is, by adjusting the relative position of the movable member 120, the connection states of the first transmission component 130, the second transmission component 140, the driving wheel set 110, and the conveying wheel set 150 can be linked and switched.

[0037] It should be noted that Figure 6 and Figure 7 the first rotation direction R1 (counterclockwise) and the second rotation direction R2 (clockwise) in Figure 6 and Figure 7 are only for illustrative purposes. The actual first rotation direction R1 can also be the second rotation direction R2 (clockwise) in Figure 6 and Figure 7 and the actual second rotation direction R2 can also be the first rotation direction R1 (counterclockwise) in Figure 6 and Figure 7 . There is no mandatory requirement in this application. That is, the actual rotation direction depends on the driving source (such as the motor 300).

[0038] The wire feeding mechanism 200 includes a guiding screw 210 and a wire feeding component 220. The guiding screw 210 is guidingly connected to the wire feeding component 220. The rotation of the conveying wheel set 150 drives the guiding screw 210 to rotate, so as to drive the wire feeding component 220 to reciprocate in the first direction. In this way, the target wire body passed through the wire feeding component 220 can move along with the movement of the wire feeding component 220.

[0039] Among them, it should be noted that in the illustrated embodiment, the first direction is the width direction W of the winding device 1. Fundamentally speaking, the specific direction of the first direction depends on the rod direction of the guiding screw 210. However, considering the winding effect, it is optimal that the first direction, that is, the rod direction of the guiding screw 210, is parallel to the length direction L of the core 2000.

[0040] In the following multiple embodiments, in order to avoid confusion and facilitate the understanding of each embodiment, the first direction can be understood as being equivalent to the width direction W of the winding device 1.

[0041] It should be understood that the driving wheel set 110 can not only transmit the driving force to the guiding screw 210 through other wheel sets or components, but also drive the core 2000 to rotate, so as to wind the target wire around the core 2000 and realize the winding operation of the core 2000.

[0042] Generally speaking, in the embodiments of this part, the driving wheel set 110 is used to provide the driving force, and the driving force is transmitted to the conveying wheel set 150 through the first transmission component 130 or the second transmission component 140, and then drives the guiding screw 210 to rotate, so as to drive the wire feeding component 220 to move in the first direction. Thus, the target wire moves along with the movement of the wire feeding component 220. With the rotation of the core 2000, the target wire can be spirally wound around the outer periphery of the core 2000.

[0043] It should be understood that the driving wheel set 110 is not the driving source. The driving source of the driving wheel set 110 can be a motor 300 or other common mechanisms or devices that can provide power, and there are no excessive constraints in this application.

[0044] In the first aspect, multiple wheel sets and components are provided in this application to transmit the driving force of the winding device 1 to the guiding screw 210, so as to realize the movement of the guiding screw 210 driving the wire feeding component 220. The settings of the driving wheel set 110, the first transmission component 130, the second transmission component 140, and the conveying wheel set 150 can synchronize the motion state of the driving wheel set 110 to the conveying wheel set 150, so that the motion state of the guiding screw 210 can be synchronized with the motion state of the driving wheel set 110. Therefore, the wire feeding component 220 can move synchronously with the motion of the driving wheel set 110, and the user can correspondingly control the number of winding turns and the turn pitch during coil winding by controlling the rotation speed of the driving wheel set 110.

[0045] On the second aspect, a movable part 120 is also provided in the present application, and the first transmission assembly 130 and the second transmission assembly 140 are both connected to the movable part 120, so that the movable part 120 can link the first transmission assembly 130 and the second transmission assembly 140 to move, so as to switch the connection status between the first transmission assembly 130, the second transmission assembly 140 and the driving wheel group 110 and the transmission wheel group 150, so as to adjust the rotation direction of the guide screw 210 so that the pay-off assembly 220 can move back and forth along the first direction. In this way, after the coil winding operation of the first batch of core bodies is completed and the second batch of core bodies is replaced, there is no need to move the pay-off assembly 220 back to the initial position. The position of the first transmission assembly 130 and the second transmission assembly 140 can be directly switched by the movable part 120, so that the winding assembly is moved back from the end point to the initial position, thereby realizing the secondary winding of the core body 2000.

[0046] In summary, the present application realizes the movement of the winding assembly by providing multiple wheel groups and multiple component structures, thereby being able to realize the winding operation at different positions of the core 2000, and the power source is single, and there is no need to set up multiple power sources; in addition, the present application also sets a movable part 120 to switch the connection status of the first transmission assembly 130 and the second transmission assembly 140 with the driving wheel group 110 and the transmission wheel group 150 to adjust the movement direction of the winding assembly accordingly, thereby reducing the operation steps that need to be reset to the winding assembly after a winding operation is completed, which not only saves the working time of the winding operation and improves the efficiency of the winding operation, but also can reduce manual intervention to a certain extent, further reduce the interference to the structure of the winding device 1 caused by manual intervention, and maintain the structural stability of the winding device 1 to a certain extent.

[0047] Please refer to Figure 8 ( Figure 8 In some embodiments, the movable part 120 has a third position relative to the driving wheel group 110 and the transmission wheel group 150. When the movable part 120 is located at the third position, the driving wheel group 110 and the first transmission assembly 130 and the second transmission assembly 140 are spaced apart, so that the driving wheel group 110 is disconnected from the transmission wheel group 150. In this way, even if the driving wheel group 110 is always in operation, the user can disconnect the first transmission assembly 130, the second transmission assembly 140 from the driving wheel group 110 and the transmission wheel group 150 by adjusting the position of the movable part 120. As a result, the driving force of the driving wheel group 110 cannot drive the transmission wheel group 150 to rotate, that is, the guide screw 210 stops rotating and the wire-releasing assembly 220 stops moving accordingly.

[0048] In combination with the actual wire winding operation scenario, when the wire feeding assembly 220 has moved from the head of the guiding screw 210 to near the tail of the guiding screw 210, if the position of the movable member 120 is not switched in time to allow the wire feeding assembly 220 to continue moving, the wire feeding assembly 220 may fall off the guiding screw 210 or have a hard contact with the associated structure connected to the guiding screw 210, causing damage to the structure in the wire winding device 1. Therefore, when the wire feeding assembly 220 moves to a position near the tail of the guiding screw 210, the movable member 120 can be switched to the third position to stop the movement of the wire feeding assembly 220. Subsequently, the wire feeding assembly 220 can be moved to the tail position of the guiding screw 210 by manually rotating the guiding screw 210. In this way, not only the integrity of the wire winding operation is ensured, but also multiple structures in the wire winding device 1 can be protected to a certain extent.

[0049] Since the rotational speed of the driving wheel set 110 driving the core body 2000 is constant, subsequent manual operations may affect the wire winding effect (such as the turn pitch) of the core body 2000. Thus, in some embodiments, the moving distance of the wire feeding assembly 220 can be set to be greater than the length of the core body 2000 for which the coil needs to be wound, so as to reduce the influence of subsequent manual operations on the wire winding result of the core body 2000.

[0050] In addition, when the driving wheel set 110 is not operating, the movable member 120 can be moved to the third position to disconnect the connections between the first transmission assembly 130, the second transmission assembly 140, the driving wheel set 110, and the conveyor wheel set 150. In this way, when the driving source (such as a motor) is accidentally turned on by an external force, it can be prevented that the wire feeding assembly 220 is driven by the guiding screw 210 to move in the first direction, causing the initial winding position of the target wire body to change and having an adverse effect on the subsequent wire winding operation.

[0051] In some other embodiments, in order to reduce the hard interference between the wire feeding assembly 220 and other structures due to excessive movement, a position sensor can be added. By sensing the position of the wire feeding assembly 220, it can be determined whether measures need to be taken to interfere with the movement of the wire feeding assembly 220. In this way, the wire winding device 1 can not only timely remind the user, but also effectively reduce the occurrence of the above situation.

[0052] In still other embodiments, the length of the guiding screw 210 can be set to be greater than the total length of the core body 2000 for which the wire winding operation needs to be performed. In this way, there is still a buffer distance after the wire feeding assembly 220 finishes winding the wire, and this buffer distance can prevent the wire feeding assembly 220 from falling off the guiding screw 210 or having a hard interference with other structures connected to the guiding screw 210.

[0053] Please refer to Figures 4 to 8 ., further, the first transmission assembly 130 includes a first gear 131 (such as Figures 6 to 8As shown in the figure, when the movable member 120 is in the first position, the first gear 131 meshes with the driving wheel set 110 and the conveyor wheel set 150. When the movable member 120 is in the second position or the third position, the first gear 131 is spaced apart from the driving wheel set 110 and the conveyor wheel set 150. In this way, through the meshing action between the gears, the driving force of the driving wheel set 110 can be transmitted to the conveyor wheel set 150, so that the conveyor wheel set 150 drives the adjusting screw 228 to rotate, causing the winding assembly to move.

[0054] In the embodiments of this part, due to the structural characteristics of the gear structure, the peripheral teeth of the gear structure are evenly and equidistantly distributed along the circumference of the gear body. Therefore, the first gear 131 can not only drive the conveyor wheel set 150 to rotate at a constant speed, and then make the adjusting screw 228 rotate at a constant speed. Thus, the winding assembly can move uniformly along the rod body direction of the guiding screw 210. Also, because the rotation of the core 2000 controlled by the driving wheel set 110 is uniform, each turn of the coil wound on the core 2000 can be evenly distributed on the surface of the core 2000. In this way, the processing yield of the winding device 1 of the present application is further improved.

[0055] Furthermore, the wire releasing mechanism 200 further includes a guiding auxiliary rod 211 and a guiding base 212. The guiding auxiliary rod 211 is parallel to and spaced from the guiding screw 210 and is connected to the guiding base 212. The wire releasing assembly 220 is slidably connected to the guiding auxiliary rod 211. In this way, when the wire releasing assembly 220 moves along the guiding screw 210, the guiding auxiliary rod 211 can provide a certain supporting effect on it, so that it can stably slide along the width direction W.

[0056] Please refer to Figures 4 to 8 , furthermore, the second transmission assembly 140 includes a second gear 141 and a third gear 142. The second gear 141 meshes with the third gear 142. When the second gear 141 rotates, the third gear 142 rotates accordingly.

[0057] When the movable member 120 is in the first position or the third position, both the second gear 141 and the third gear 142 are spaced apart from the driving wheel set 110 and the conveyor wheel set 150, and the adjusting screw 228 stops rotating. When the movable member 120 is in the second position, the second gear 141 meshes with the driving wheel set 110, and the third gear 142 meshes with the conveyor wheel set 150. In this way, the driving force of the driving wheel set 110 can be transmitted to the conveyor wheel set 150, thereby driving the adjusting screw 228 to rotate to drive the wire releasing assembly 220 to move.

[0058] Wherein, when both the first transmission assembly 130 and the second transmission assembly 140 are gear assemblies, the first transmission assembly 130 includes a first gear 131, and the second transmission assembly 140 includes a second gear 141 and a third gear 142. Alternatively, the number of gears included in the first transmission assembly 130 is one less than the number of gears included in the second transmission assembly 140. In this way, when the transmission wheel set 150 is connected to the first transmission assembly 130 and the second transmission assembly 140 respectively, the rotation directions of the transmission wheel set 150 are opposite, that is, under different connection relationships, the moving directions of the wire feeding assembly 220 are opposite. In this way, the reciprocating movement of the wire feeding assembly 220 along the first direction is realized.

[0059] For reference Figure 4 and Figure 8 , in some embodiments, the driving wheel set 110 and the transmission wheel set 150 are arranged at intervals along the height direction H of the winding mechanism 100, and the first transmission assembly 130 and the second transmission assembly 140 are located between the driving wheel set 110 and the transmission wheel set 150; along the length direction L of the winding mechanism 100, the first transmission assembly 130 is located on the first side of the transmission wheel set 150, and the second transmission assembly 140 is located on the second side of the transmission wheel set 150, wherein the first side and the second side are arranged oppositely. In this way, a certain distance can be generated between the first transmission assembly 130, the second transmission assembly 140 and the driving wheel set 110 and the transmission wheel set 150, and the distance can be changed with the movement of the movable member 120 to realize the switching of different connection states between the components and the wheel sets.

[0060] The movable member 120 moves along the length direction L of the winding mechanism 100 to drive the first transmission assembly 130 and the second transmission assembly 140 to reciprocate to the first position and the second position, thereby switching the connection state between the components and the wheel sets, correspondingly switching the rotation state of the adjusting screw 228, and causing the movement state of the wire feeding assembly 220 to be switched accordingly.

[0061] For reference Figures 3 to 8 , further, the winding mechanism 100 further includes a motor 300, and the motor 300 can provide the kinetic energy required by the driving wheel set 110 to make the driving wheel set 110 rotate.

[0062] The driving wheel set 110 includes a main driving wheel 111 and a slave driving wheel 112. Along the height direction H, the main driving wheel 111 meshes with the slave driving wheel 112. The output shaft of the motor 300 is drivingly connected to the main driving wheel 111 to indirectly drive the slave driving wheel 112 to rotate. When the movable member 120 is in the first position, the slave driving wheel 112 meshes with and connects to the first transmission assembly 130 and is spaced apart from the second transmission assembly 140. When the movable member 120 is in the second position, the slave driving wheel 112 meshes with and connects to the second transmission assembly 140 and is spaced apart from the first transmission assembly 130. In this way, the motion state of the conveyor wheel set 150 is correspondingly switched, and further, the moving state of the wire pay-off assembly 220 is controlled.

[0063] Among them, the driving wheel set 110 is set as a structure with two driving wheels, namely the main driving wheel 111 and the slave driving wheel 112. That is, the driving wheel directly connected to the output shaft of the motor 300 and the driving wheel connected to other gears are decoupled. This can not only enable the driving wheel set 110 to adapt to the shape of the installation space it needs, but also disperse the load on the gears of the driving wheels, thereby reducing the loss of each driving wheel and improving the service life of the driving wheel set 110.

[0064] For reference Figures 6 to 8 , further, the radial dimension of the main driving wheel 111 is smaller than that of the slave driving wheel 112. In this way, the slave driving wheel 112 can increase the driving torque, and the rotation speed of the slave driving wheel 112 is lower than the rotation speed of the output shaft of the motor 300, so as to match the actual operation requirements of the winding device 1.

[0065] Optionally, the radial dimension of the main driving wheel 111 is larger than that of the slave driving wheel 112. In this way, the rotation speed of the slave driving wheel 112 can be higher than the rotation speed of the output shaft of the motor 300, and the driving torque received by the slave driving wheel 112 can be reduced. The specific selection needs to be determined according to the actual requirements of the winding device 1.

[0066] For reference Figures 3 to 8 , in some embodiments, the winding mechanism 100 further includes an installation main body 160. The installation main body 160 includes a first installation plate 161 and a second installation plate 162, and is provided with an installation cavity 163 for installing the wheel set assembly. The first installation plate 161 and the second installation plate 162 are respectively located on opposite sides of the installation cavity 163. The driving wheel set 110, the movable member 120, the first transmission assembly 130, the second transmission assembly 140, and the conveyor wheel set 150 are all located in the installation cavity 163 and are rotatably connected to the first installation plate 161.

[0067] The first mounting plate 161 is provided with a first slide groove 1611, and the second mounting plate 162 is provided with a second slide groove. The first slide groove 1611 is connected to the second slide groove to form a slideway for the movable part 120 to slide. Along the width direction W of the winding device 1, the opposite sides of the movable part 120 are slidably connected to the first slide groove 1611 and the second slide groove respectively, and slide along the groove body direction of the first slide groove 1611 and the second slide groove, so as to realize the position switching of the movable part 120 relative to the mounting body 160.

[0068] Among them, in the illustrated embodiment, the first slide groove 1611 and the second slide groove have the same structural features, and the first mounting plate 161 and the second mounting plate 162 have the same shape, but due to certain differences in their installation positions and connection relationships, the words "first" and "second" are used to distinguish them. However, the structural features of the first slide groove 1611 can refer to the structural features of the second slide groove. Therefore, only the first slide groove 1611 is identified in the figure, and the second slide groove is not identified. In each embodiment, the structural features of the second slide groove can be obtained based on the first slide groove 1611.

[0069] For reference Figures 3 to 5 Furthermore, the winding mechanism 100 also includes a regulating frame 170, which includes a pull rod 171, a limit rod 172 and a connecting assembly 173. The end of the connecting assembly 173 is connected to the movable part 120 and is provided with a connecting space 174. The connecting assembly 173 extends along the length direction L of the winding mechanism 100. The pull rod 171 and the limit rod 172 are located in the connecting space 174 and are spaced apart along the length direction L of the winding mechanism 100.

[0070] The pull rod 171 is located outside the installation cavity 163 for user use, and the limit rod 172 is at least partially located in the installation cavity 163. The pull rod 171 moves to make the connecting assembly 173, the limit rod 172 and the movable part 120 move along the groove direction of the first slide groove 1611 and the second slide groove. That is, the user moves the pull rod 171 to drive the limit rod 172 and the connecting assembly 173 to move, thereby adjusting the position of the movable part 120 in conjunction, and realizing the state switching between the first transmission assembly 130, the second transmission assembly 140 and the driving wheel group 110 and the transmission wheel group 150.

[0071] Among them, the limit rod 172 can have a restraining effect on the side walls of the first slide groove 1611 and the second slide groove, so that the excessive movement of the movable part 120 can be avoided, and the first transmission component 130 or the second transmission component 140 and the driving wheel group 110 and the transmission wheel group 150 can be avoided from damaging each other due to excessive displacement, thereby protecting the structural stability of the winding mechanism 100 to a certain extent.

[0072] Please continue to refer to Figures 3 to 5, Further, the first chute 1611 is provided with at least one first partition convex portion 1612, and the second chute is provided with at least one second partition convex portion. Along the width direction W, the first partition convex portions 1612 and the second partition convex portions are arranged in one-to-one correspondence to partition the slideway into multiple segments. Among them, the structural features of the second partition convex portion can refer to the structural features of the first partition convex portion 1612 in the attached drawings.

[0073] The connecting component 173 is rotatably connected to the movable member 120 to drive the movable member 120 to move along the groove body directions of the first chute 1611 and the second chute, so that the movable member 120 moves to the first position or the second position. Among them, the connecting component 173 can drive the limiting member to avoid the first partition convex portion 1612 and the second partition convex portion when the regulating frame 170 moves by rotating relative to the movable member 120, reducing the interference of the first partition convex portion 1612 and the second partition convex portion on the movement of the limiting member. Thus, the movable member 120 can move smoothly.

[0074] Further, chamfering designs are made at the ends of the first partition convex portion 1612 and / or the second partition convex portion to reduce the interference of the first partition convex portion 1612 and / or the second partition convex portion on the limiting member during the movement of the limiting member. At the same time, it can guide the movement of the limiting rod 172 to a certain extent.

[0075] Please refer to Figure 9 and Figure 10 , In some embodiments, the wire feeding assembly 220 includes an upper limiting bracket 221, a lower limiting bracket 222 and a movable base 229. The upper limiting bracket 221 and the lower limiting bracket 222 are movably connected and can move relatively closer to or away from each other along the height direction H. The upper limiting bracket 221 and the lower limiting bracket 222 jointly form a wire passing space by constraint. This wire passing space is used for the target wire body to pass through and can adjust the space size correspondingly according to the relative distance between the upper limiting bracket 221 and the lower limiting bracket 222.

[0076] The movable base 229 is guidingly connected to the guiding screw 210 and is rotatably connected to the lower limiting bracket 222. When the target wire body is located in the wire passing channel 2221 and abuts against the upper limiting bracket 221, the lower limiting bracket 222 can rotate relative to the movable base 229. Thus, by moving the lower limiting bracket 222, the abutting effect between the upper limiting bracket 221 and the target wire body can be relieved, thereby relieving the tension effect of the target wire body and avoiding the target wire body from being overly tightened and broken, which affects the winding operation process and efficiency of the winding device 1.

[0077] Please continue to refer to Figure 9 and Figure 10, Further, the wire pay - off assembly 220 further includes a reset member 227. One end of the reset member 227 is connected to the lower limit bracket 222, and the other end is connected to the movable base 229. Thus, when the lower limit bracket 222 rotates relative to the movable base 229, the reset member 227 can provide a certain restoring effect to reset the limit bracket. At the same time, the reset member 227 can also restrict the rotation angle of the lower limit bracket 222 to a certain extent, reducing the influence on the restraint effect of the wire pay - off assembly 220 on the target wire due to excessive rotation of the lower limit bracket 222.

[0078] Please continue to refer to Figure 9 and Figure 10 , Optionally, the wire pay - off assembly 220 includes a wire dividing wheel 223, a wire pressing wheel 224, and a wire passing wheel 225. The wire dividing wheel 223 and a part of the wire pressing wheels 224 are rotatably connected to the lower limit bracket 222, and another part of the wire pressing wheels 224 are rotatably connected to the upper limit bracket 221. The wire passing wheel 225 is rotatably connected to the movable base 229. Among them, the wire dividing wheel 223 is used to separate multiple target wires to prevent multiple wires from participating in the winding operation process simultaneously. The wire pressing wheels 224 are located in the wire threading channel 2221. Through the combined action with the upper limit bracket 221 and the lower limit bracket 222, multiple wire pressing wheels 224 jointly press the target wire to keep it in a tensioned state. The wire passing wheel 225 is used to support the target wire to prevent its suspended part from being too long and sagging due to gravity, affecting the tensioning effect of the target wire and thus affecting the efficiency of the winding operation.

[0079] It should be noted that unstable control of the tension of the target wire is likely to cause uneven density of the wound coil, thus affecting the electrical performance of the motor 300. In severe cases, it may even cause the wound coil to become loose and collapse. Therefore, in the height direction H, the height position of the wire passing wheel 225 can be set according to the height position of the core 2000 and the height position of the upper limit bracket 221. The purpose of setting the wire passing wheel 225 is to reduce the deformation amount of the target wire during the transmission process, so that the target wire can always be in an ideal tensioned state.

[0080] Please continue to refer to Figure 9 and Figure 10 , The wire pay - off assembly 220 further includes a scale 226. The scale 226 is connected to the movable platform and extends along the height direction H. When the upper limit bracket 221 moves closer to the lower limit bracket 222, in the wire threading channel 2221, the upper limit bracket 221 can drive the wire pressing wheel 224 to move along the height direction H relative to the lower limit bracket 222. Thus, the scale 226 can measure the deformation amount of the target wire pressed in the height direction H, and the user can measure the tensioning effect of the target wire accordingly based on this deformation amount.

[0081] Please continue to refer to Figure 9 and Figure 10, optionally, the wire pay-off assembly 220 further includes an adjusting screw 228 that passes through the upper limit bracket 221 and is screwed to the lower limit bracket 222. In this way, the user can rotate the adjusting screw 228 to correspondingly adjust the relative distance between the upper limit bracket 221 and the lower limit bracket 222, thereby driving the relative positions of the plurality of wire pressing wheels 224 to move, so as to be able to adjust the tension of the target wire body to a certain extent.

[0082] Reference may be made together to Figures 6 to 8 and Figure 11 , in some embodiments, the conveyor pulley group 150 includes a conveyor driving wheel 151 and a first synchronous wheel 152. When the movable member 120 is in the first position, the conveyor driving wheel 151 is connected to the first transmission assembly 130. When the movable member 120 is in the second position, the conveyor driving wheel 151 is connected to the second transmission assembly 140; the conveyor driving wheel 151 is drivingly connected to the first synchronous wheel 152 and drives the first synchronous wheel 152 to rotate synchronously. The wire pay-off mechanism 200 further includes a second synchronous wheel 230, and the second synchronous wheel 230 drives the guide screw 210. The winding device 1 further includes a synchronous belt 400, one side of the synchronous belt 400 is sleeved on the first synchronous wheel 152, and the other side is sleeved on the second synchronous wheel 230.

[0083] In this way, the synchronous belt 400 can synchronize the motion states of the conveyor driving wheel 151 and the guide screw 210. When the diameters of the first synchronous wheel 152 and the second synchronous wheel 230 are the same, the rotation speeds of the first synchronous wheel 152 and the guide screw 210 are the same. When the diameter of the first synchronous wheel 152 is greater than the diameter of the second synchronous wheel 230, the rotation speed of the first driving wheel is less than the rotation speed of the second synchronous wheel 230. When the diameter of the first synchronous wheel 152 is less than the diameter of the second synchronous wheel 230, the rotation speed of the first driving wheel is greater than the rotation speed of the second synchronous wheel 230.

[0084] Further, when the first synchronous wheel 152 is connected to the wheel body surface of the conveyor driving wheel 151, that is, the rotation speed of the first synchronous wheel 152 is equal to the rotation speed of the conveyor driving wheel 151. At this time, the rotation speed of the guide screw 210 can be correspondingly adjusted by adjusting the diameter of the second synchronous wheel 230, that is, when the diameters of the first synchronous wheel 152 and the second synchronous wheel 230 are the same, the rotation speeds of the conveyor driving wheel 151 and the guide screw 210 are the same. When the diameter of the first synchronous wheel 152 is greater than the diameter of the second synchronous wheel 230, the rotation speed of the conveyor driving wheel 151 is less than the rotation speed of the second synchronous wheel 230. When the diameter of the first synchronous wheel 152 is less than the diameter of the second synchronous wheel 230, the rotation speed of the conveyor driving wheel 151 is greater than the rotation speed of the second synchronous wheel 230.

[0085] Reference may be made to Figures 12 to 14, Optionally, the winding device 1 further includes a positioning mechanism 500. The positioning mechanism 500 includes a positioning base 510, an adjusting rod 520, and a movable block 530. The positioning base 510 is provided with a positioning channel 511. The adjusting rod 520 is movably connected to the positioning base 510. The movable block 530 is located between the positioning mechanism 500 and the winding mechanism 100. The end of the adjusting rod 520 passes through the positioning channel 511 and is connected to the movable block 530 to drive the movable block 530 to reciprocate along the width direction W of the winding device 1. In this way, by adjusting the distance between the movable block 530 and the winding mechanism 100, cores 2000 of different sizes can be correspondingly placed, increasing the applicable range of the winding device 1.

[0086] When it comes to the winding operation of multiple cores of the same specification, the relative distance between the movable block 530 and the winding mechanism 100 can also be adjusted to correspondingly place multiple cores. However, it should be noted that in order to avoid no space reservation at the connection of multiple cores when winding the coil, a partition 3000 can be provided between adjacent cores to prevent the coil from winding multiple cores directly as a whole large-size core.

[0087] Combined with the foregoing embodiments, it can be seen that the movable member further has a third position relative to the driving wheel set 110 and the transmission wheel set 150. When the movable member 120 is in the third position (as Figure 8 shown), the driving wheel set 110 is spaced from both the first transmission assembly 130 and the second transmission assembly 140, disconnecting the connection between the driving wheel set 110 and the transmission wheel set 150. In this way, when the target wire body encounters the partition 3000 on the moving path driven by the wire releasing assembly 220, the position of the movable member 120 can be moved to the third position to stop the rotation of the guiding screw 210. Thus, the wire releasing assembly 220 stops rotating. At this time, the user can manually operate the guiding screw 210. After the wire releasing assembly 220 drives the target wire body to cross the partition 3000, the movable member 120 is moved to the first position (as Figure 6 ) or the second position (as Figure 7 ) to complete the winding operation of the next core 2000.

[0088] Optionally, the user can also stop the driving source (such as a motor) and manually rotate the guiding screw 210 to drive the wire releasing assembly 220 to move. After the wire releasing assembly 220 crosses the position of the partition 3000, the driving source is restarted for operation.

[0089] Please continue to refer to Figures 12 to 14, Further, the positioning mechanism 500 is provided with a support bearing 570. The adjusting screw rod 228 passes through the support bearing 570 and can reciprocate relative to the support bearing 570 in the width direction W, so as to adjust the distance between the movable block 530 and the winding mechanism 100. The support bearing 570 can reduce the loss caused by relative displacement between the adjusting screw rod 228 and the positioning base 510, and extend the service life of the positioning mechanism 500 to a certain extent.

[0090] Please continue to refer to Figures 12 to 14 , Optionally, the positioning mechanism 500 is further provided with a guiding slide rod 560. The guiding slide rod 560 passes through the positioning channel 511 and is arranged in parallel and spaced apart from the adjusting screw rod 228. The end of the guiding slide rod 560 is connected to the movable block 530. In this way, the guiding slide rod 560 and the adjusting screw rod 228 jointly support the movable block 530, which can not only increase the connection stability between the movable block 530 and the rod structure, but also provide a certain supporting effect on the movable block 530 when the adjusting screw rod 228 drives the movable block 530 to move, so that it moves smoothly relative to the positioning base 510.

[0091] Optionally, the winding mechanism 100 further includes an abutting member 540 and a wire pressing member 550. The abutting member 540 is used to abut against the core body 2000, and the wire pressing member 550 is used to press the end of the target wire body against the mounting body 160 or bind the end of the target wire body.

[0092] Further, the movable member 120 is provided with a first positioning groove 531, and the abutting member 540 is provided with a second positioning groove 541. Both the first positioning groove 531 and the second positioning groove 541 can be customized according to the actual cross-sectional size of the core body 2000 to enhance the fixing effect of the movable member 120 and the abutting member 540 on the core body 2000.
