Description

Technical Field

[0002] Winding machines are key equipment in the mass production of electric motors. They are widely used in the coil winding process, improving coil production efficiency and enabling automated winding and trimming. Coil winding typically uses round wire or flat wire. As motor performance requirements increase, flat wire, with its rectangular cross-section, can better fill gaps in motor coils, significantly improving the motor's slot fill rate and overall performance. Consequently, flat wire is increasingly being used for coil winding.

[0041] The following will be combined with the accompanying drawings in the embodiments of this application to clearly and completely describe the technical solutions in the embodiments of this application. Obviously, the embodiments described are only part of the embodiments of this application, not all of them. Based on the embodiments in this application, all other embodiments obtained by ordinary technicians in this field without making any creative efforts are within the scope of protection of this application.

[0042] The wire used to wind motor coils is typically divided into round wire and flat wire. Round wire has good symmetry, and traditional winding machines are mostly suitable for round wire. However, as motor performance requirements increase, flat wire, with its rectangular cross-section, can better fill the gaps in the motor's coils, significantly improving the motor's slot fill rate and overall performance. Therefore, in the production of high-power-density motors, more and more motor coils are being wound using flat wire. However, existing winding machines are mostly suitable for round wire, and the wire may twist multiple times during the coil winding process. Therefore, when using flat wire to wind coils, the flat wire may be over-twisted, affecting its integrity. Coils wound with twisted flat wire can have uneven wiring and even damage the wire, affecting the quality of the coil and, in turn, the quality of the motor using it.

[0043] Furthermore, conventional wire-gripping and shearing devices are typically coaxially coupled to the winding shaft, meaning they rotate synchronously. This coupling prevents independent control of wire gripping and cutting, and winding, limiting the flexibility and precision of the winding machine.

[0044] In addition, when the production capacity of a single winding machine is not full and different models of motors need to be produced during the production scheduling process, due to the difference in wire diameter, it is usually necessary to replace the wire clamping and cutting device and shut down for debugging for a long time. Quick switching cannot be achieved, resulting in extended production preparation time and reduced production efficiency of the winding machine.

[0045] In order to solve at least one of the above-mentioned problems, an embodiment of the present application provides a wire-gripping and shearing device, which is applied to a winding device, wherein the winding device includes a rotatable winding shaft, and the wire is wound into a coil by the rotation of the winding shaft, and the wire-gripping and shearing device is configured to clamp and cut the portion of the wire connected to the coil. The wire-gripping and shearing device includes a first shearing assembly, including a first annular structure and a first shearing piece connected to each other, the axis of the first annular structure extends along a first direction, the first shearing piece has a first shearing portion, the outer side surface of the first annular structure has a long groove, and the extension direction of the long groove is set at an acute angle to the first direction; a clamping assembly, including an open-loop structure and a clamping piece, the open-loop structure is mounted on the first annular structure, the first end of the open-loop structure is elastically connected to the first shearing assembly, the clamping piece is connected to the second end of the open-loop structure, and the clamping piece has a first clamping portion; a second shearing assembly, including a second annular structure, a second shearing piece connected to the second annular structure, and a first A protruding structure, a second annular structure is mounted on the first annular structure, the second shearing piece has a second shearing portion and a second clamping portion, the second shearing portion is arranged opposite to the first shearing portion, the second clamping portion is arranged opposite to the first clamping portion, the first protruding structure extends into the long groove and can slide along the extension direction of the long groove, wherein the outer side surface of the second annular structure has an arc groove extending along the circumference of the second annular structure; the first driving assembly can extend into the arc groove and is configured to drive the second annular structure to slide relative to the first annular structure in a first direction and rotate around the axis of the first annular structure to drive the second shearing piece to approach the clamping piece and the first shearing piece in sequence.

[0046] The second annular structure is driven by the first driving component to slide relative to the first annular structure in the first direction, so that the first protrusion structure connected to the second annular structure slides along the extension direction of the long groove. Since the extension direction of the long groove is set at an acute angle to the first direction, the second annular structure can slide relative to the first annular structure in the first direction while also being able to rotate around the axis of the first annular structure, so that the second annular structure drives the second shearing piece close to the clamping piece to clamp the wire between the clamping piece and the second shearing piece.

[0047] Then, the second annular structure drives the second shearing member to continue rotating around the axis of the first annular structure, and pushes the clamping member to rotate around the axis of the first annular structure, so that the second shearing portion of the second shearing member approaches the first shearing portion of the first shearing member, so that the wire between the second shearing portion and the first shearing portion is cut. In other words, by driving the rotation of the second annular structure, the wire can be clamped first and then cut, and the clamping and shearing can be completed without twisting the wire, thereby preventing the wire from being damaged by twisting during the processing process.

[0048] The coil wound with the untwisted wire is arranged neatly, thereby improving the quality of the coil and thus improving the quality of the motor using the coil.

[0049] Furthermore, by driving the rotation of the second annular structure to first clamp the wire and then cut it, the rotation angle of the second annular structure can be adjusted according to the cross-sectional dimensions of the wire, making the wire-clamping and shearing device suitable for wires of various sizes and highly versatile. When the production capacity of a single winding machine is insufficient and different motor models need to be produced during the production scheduling process, the machine can quickly switch between them without having to replace the wire-clamping and shearing device, thereby improving the production efficiency of the winding equipment.

[0050] In addition, the movements of the wire clamping and shearing device and the winding shaft do not interfere with each other, which eliminates the coupling between the wire clamping and shearing device and the winding shaft, allowing the actions of clamping and shearing the wire and winding the coil to be controlled and debugged separately, improving the accuracy and flexibility of the winding equipment and meeting the needs of different production processes.

[0051] The specific structures of the wire cutting device and the winding equipment are described below with reference to the accompanying drawings and specific embodiments.

Figure 9 Shown is a structural schematic diagram of a shear line device provided by another embodiment of the present application after removing the second shearing component. Figure 10 Shown is a structural schematic diagram of the shearing line device provided by another embodiment of the present application after removing the second shearing component and the clamping component. Figure 11 Shown is a side view of a clipping and shearing line device provided in one embodiment of the present application. Figure 12 The following is an example of an embodiment of the present application. Figure 11 The shown figure is a partial enlarged view of the shear line device in area B. Figure 13 Shown is a front view of a clipping and shearing line device provided in one embodiment of the present application. Figure 14 The following is an example of an embodiment of the present application. Figure 13 The cross-sectional diagram of the shearing line device in the CC direction is shown in FIG. Figures 1 to 14 As shown, the shearing line device 10 includes a first shearing assembly 100 , a clamping assembly 200 , a second shearing assembly 300 and a first driving assembly 400 .

[0053] like Figure 1 As shown, the wire cutting device 10 is applied to a winding device 1. The winding device 1 includes a rotatable winding shaft 20, and the wire 40 is wound into a coil 50 by the rotation of the winding shaft 20. The wire cutting device 10 is configured to clamp and cut the portion of the wire 40 connected to the coil 50.

[0054] The first shearing assembly 100 includes a first annular structure 110 and a first shearing piece 120 connected to each other. The axis of the first annular structure 110 extends along the first direction X. Exemplarily, the first annular structure 110 can be a circular ring, or a combination of multiple coaxially connected circular rings. The first shearing piece 120 has a first shearing portion 121. Exemplarily, the first shearing piece 120 can be a structure with a blade, such as a cutter or scissors. The first shearing portion 121 is the blade of the first shearing piece 120. The outer side surface of the first annular structure 110 has a long groove 111. The extension direction of the long groove 111 is set at an acute angle to the first direction X. Exemplarily, the long groove 111 can be a long strip-shaped groove, such as a waist-shaped groove, a rectangular groove, etc. The extension direction of the long groove 111 is set at an acute angle to the first direction X, which can be understood as the extension direction of the long groove 111 is neither parallel to the first direction X nor perpendicular to the first direction X.

[0055] The clamping assembly 200 includes an open-loop structure 210 and a clamping member 220. Exemplarily, the open-loop structure 210 is an annular structure with an opening, such as a semicircular ring structure, a multi-semicircular ring structure, or the like. The cross-sectional shape of the open-loop structure 210 can be rectangular, circular, triangular, or the like. The open-loop structure 210 is mounted on the first annular structure 110 and can rotate around the first annular structure 110. The first end 211 of the open-loop structure is elastically connected to the first shearing assembly 100, and the clamping member 220 is connected to the second end 212 of the open-loop structure. The clamping member 220 has a first clamping portion 221. Exemplarily, the clamping member 220 can be a plate-like structure, a block-like structure, or the like. Exemplarily, the first clamping portion 221 can be a surface or a point of the clamping member 220. In practical applications, the first clamping portion 221 can be set as a surface of the clamping member 220 to increase the contact area between the first clamping portion 221 and the wire 40, increase the friction between the first clamping portion 221 and the wire 40, and improve the clamping effect.

[0056] The second shearing assembly 300 includes a second annular structure 310, a second shearing member 320 connected to the second annular structure 310, and a first protruding structure 330. The second annular structure 310 is mounted on the first annular structure 110 and can rotate about the first annular structure 110. The second shearing member 320 has a second shearing portion 321 and a second clamping portion 322. The second shearing portion 321 is disposed opposite the first shearing portion 121. The second clamping portion 322 is disposed opposite the first clamping portion 221. For example, the second annular structure 310 can be a single ring or a combination of multiple coaxially connected rings. For example, the second shearing member 320 can be a structure with a blade, such as a cutter or scissors. The second shearing portion 321 serves as the blade of the second shearing member 320. For example, the first protruding structure 330 can be a cylindrical protrusion, a block-shaped protrusion, or an irregularly shaped protrusion, as long as it can extend into the elongated slot 111 and slide along the extending direction of the elongated slot 111. For example, the second clamping portion 322 can be a surface or a point of the second shearing member 320. In practical applications, the second clamping portion 322 can be set as a surface of the second shearing member 320 to increase the contact area between the second clamping portion 322 and the wire 40, increase the friction between the second clamping portion 322 and the wire 40, and improve the clamping effect.

[0057] The first protrusion 330 extends into the elongated groove 111 and is slidable along the extending direction of the elongated groove 111. The outer side surface of the second annular structure 310 has an arcuate groove 311 extending along the circumference of the second annular structure 310. For example, the arcuate groove 311 can be an annular groove extending along the circumference of the second annular structure 310, a semicircular annular groove extending along the circumference of the second annular structure 310, or a segment of an arcuate groove extending along the circumference of the second annular structure 310.

[0058] The first drive assembly 400 can extend into the arc groove 311. The first drive assembly 400 is configured to drive the second annular structure 310 to slide relative to the first annular structure 110 along the first direction X and rotate around the axis of the first annular structure 110, thereby driving the second shearing member 320 to sequentially approach the clamping member 220 and the first shearing member 120. For example, the first drive assembly 400 can be a component capable of achieving linear drive, such as a cylinder or a linear motor.

[0059] The second annular structure 310 is driven by the first driving assembly 400 to slide relative to the first annular structure 110 along the first direction X, so that the first protrusion structure 330 connected to the second annular structure 310 slides along the extension direction of the long groove 111. Since the extension direction of the long groove 111 is set at an acute angle to the first direction X, the second annular structure 310 can slide relative to the first annular structure 110 along the first direction X while also being able to rotate around the axis of the first annular structure 110, so that the second annular structure 310 drives the second shearing member 320 to approach the clamping member 220 to clamp the wire between the clamping member 220 and the second shearing member 320. Then, the second annular structure 310 drives the second shearing member 320 to continue rotating around the axis of the first annular structure 110, and pushes the clamping member 220 to rotate around the axis of the first annular structure 110, so that the second shearing portion 321 of the second shearing member 320 approaches the first shearing portion 121 of the first shearing member 120, so that the wire 40 located between the second shearing portion 321 and the first shearing portion 121 is cut. In other words, by driving the second annular structure 310 to rotate, the wire 40 can be clamped first and then cut, and the clamping and shearing can be completed without twisting the wire 40, thereby preventing the wire 40 from being damaged by twisting during the processing.

[0060] In some embodiments, the shearing line device 10 further includes an elastic component 500. A first end 501 of the elastic component is connected to the first end 211 of the open-loop structure, and a second end 502 of the elastic component is connected to a side of the first shearing member 120 near the first shearing portion 121. For example, the elastic component 500 may be an elastic structure such as a spring or rubber member. The two ends of the spring are respectively connected to the first end 211 of the open-loop structure and a side of the first shearing member 120 near the first shearing portion 121.

[0061] The following describes the process of clamping and cutting the wire 40 by taking the elastic component 500 as a spring as an example.

[0062] The first drive assembly 400 drives the second annular structure 310 to slide relative to the first annular structure 110 along the first direction X, so that the first protrusion structure 330 connected to the second annular structure 310 slides along the extension direction of the long groove 111. Since the extension direction of the long groove 111 is set at an acute angle to the first direction X, the second annular structure 310 can slide relative to the first annular structure 110 along the first direction X while also rotating around the axis of the first annular structure 110 (taking clockwise rotation around the axis of the first annular structure 110 as an example), so that the second annular structure 310 drives the second shearing piece 320 to approach the clamping piece 220 to clamp the wire 40 located between the clamping piece 220 and the second shearing piece 320.

[0063] After the second annular structure 310 drives the second shearing member 320 toward the clamping member 220 to clamp the wire 40 located between the clamping member 220 and the second shearing member 320, the second annular structure 310 drives the second shearing member 320 to continue rotating about the axis of the first annular structure 110, thereby pushing the clamping member 220 to rotate about the axis of the first annular structure 110. The open-loop structure 210 also rotates about the axis of the first annular structure 110, compressing the spring. The second annular structure 310 drives the second shearing member 320 to continue rotating about the axis of the first annular structure 110, and the second shearing portion 321 of the second shearing member 320 gradually approaches the first shearing portion 121 of the first shearing member 120, thereby shearing the wire 40 located between the second shearing portion 321 and the first shearing portion 121.

[0064] After the wire 40 is cut, the first drive assembly 400 stops driving the second annular structure 310, or the first drive assembly 400 drives the second annular structure 310 to slide in the opposite direction relative to the first annular structure 110 along the first direction X, and the second annular structure 310 rotates counterclockwise around the axis of the first annular structure 110, so that the second annular structure 310 drives the second shearing member 320 away from the clamping member 220 to loosen the wire 40 located between the clamping member 220 and the second shearing member 320.

[0065] Under the action of the tension (also called compression force) of the spring, the open-loop structure 210 rotates counterclockwise around the axis of the first annular structure 110 , so that the open-loop structure 210 drives the clamping member 220 to reset.

[0066] The elastic component 500 is used to realize the elastic connection between the first end 211 of the open-loop structure and the first shearing component 100 . This has a simple structure and facilitates the resetting of the clamping member 220 .

[0067] In some embodiments, as Figure 13 As shown, a first perpendicular distance L1 between the second shearing portion 321 and the axis of the first annular structure 110 is equal to a second perpendicular distance L2 between the first shearing portion 121 and the axis of the first annular structure 110. In other words, the second shearing portion 321 and the first shearing portion 121 are located on the same circumferential surface, enabling the second shearing portion 321 to contact the first shearing portion 121 to better cut the wire 40.

[0068] In actual applications, due to process errors, the first vertical distance L1 may be slightly larger or smaller than the second vertical distance L2. The first vertical distance L1 slightly larger or smaller than the second vertical distance L2 due to process errors can be considered to be equal to the second vertical distance L2.

[0069] In some embodiments, the first annular structure 110 includes a first hollow shaft segment 112 and a second hollow shaft segment 113. The second hollow shaft segment 113 is coaxially connected to the first hollow shaft segment 112. The outer diameter of the second hollow shaft segment 113 is smaller than the outer diameter of the first hollow shaft segment 112. For example, the first hollow shaft segment 112 and the second hollow shaft segment 113 can both be annular structures. For example, the inner diameter of the second hollow shaft segment 113 can be equal to or smaller than the inner diameter of the first hollow shaft segment 112.

[0070] The second annular structure 310 is sleeved on the first hollow shaft segment 112. The open-loop structure 210 is sleeved on the second hollow shaft segment 113. The first shearing piece 120 is connected to the first hollow shaft segment 112 and extends toward one end of the first hollow shaft segment 112 close to the second hollow shaft segment 113. The first shearing piece 120 includes a first curved plate-like structure 122, and the outer side surface of the first curved plate-like structure 122 is coplanar with the outer side surface of the first annular structure 110. The clamping piece 220 includes a second curved plate-like structure 222, and the inner side surface of the second curved plate-like structure 222 is in contact with the outer side surface of the first curved plate-like structure 122. The second shearing piece 320 includes a third curved plate-like structure 323, and the inner side surface of the third curved plate-like structure 323 is coplanar with the inner side surface of the second curved plate-like structure 222.

[0071] The structure provided by this embodiment is simple and compact, and can ensure better clamping and shearing effects.

[0072] For example, Figure 4 and Figure 14 As shown, the shear line device 10 further includes an open-loop cover plate 810. The open-loop cover plate 810 is sleeved on the second hollow shaft segment 113, connected to the second hollow shaft segment 113, and located on a side of the open-loop structure 210 away from the first hollow shaft segment 112 to prevent the open-loop structure 210 from falling off from the second hollow shaft segment 113.

[0073] In some embodiments, the first protruding structure 330 includes a first connecting shaft 331 and a first roller 332. The first connecting shaft 331 is connected to the second annular structure 310. For example, the first connecting shaft 331 and the second annular structure 310 can be connected by bolts and nuts. For example, the first connecting shaft 331 can have a threaded section, and the second annular structure 310 can have a threaded hole, so that the first connecting shaft 331 and the second annular structure 310 can be threadedly connected. The first roller 332 is rotatably connected to the first connecting shaft 331. For example, the first roller 332 can be a bearing. For example, the first roller 332 can be a needle roller bearing, a deep groove ball bearing, etc.

[0074] The first roller 332 extends into the long groove 111 and rolls in contact with the side wall of the long groove 111, thereby reducing the friction between the first roller 332 and the long groove 111 and reducing the force required to drive the second shearing assembly 300. This allows the use of a first drive assembly 400 with a smaller size and load, further reducing the size of the shearing line device 10.

[0075] In some embodiments, the second annular structure 310 includes a third hollow shaft segment 312, a first flange 313, and a second flange 314. The third hollow shaft segment 312 is sleeved onto the first annular structure 110. The first flange 313 is connected to the first end 3121 of the third hollow shaft segment. The second flange 314 is connected to the second end 3122 of the third hollow shaft segment. A circular arc groove 311 is formed between the second flange 314 and the first flange 313.

[0076] For example, the third hollow shaft segment 312, the first flange 313, and the second flange 314 can all be annular structures. By providing two flanges at both ends of the third hollow shaft segment 312 to form an annular arc groove 311, there is no need to specifically rotate the second annular structure 310 to extend the first drive assembly 400 into the arc groove 311, thereby facilitating assembly and commissioning of the wire cutting device 10.

[0077] In some embodiments, the first drive assembly 400 includes a first drive source 410, a first drive member 420, at least two second connecting shafts 430, and at least two second rollers 440. The first drive member 420 is connected to the first drive source 410 and moves along the first direction X under the drive of the first drive source 410. For example, the second connecting shaft 430 and the first drive member 420 can be connected by bolts and nuts. For example, the second connecting shaft 430 can have a threaded section, and the first drive member 420 can have a threaded hole so that the second connecting shaft 430 and the first drive member 420 are screwed together. For example, the first drive source 410 can be a structure capable of achieving linear drive, such as a linear motor or a cylinder. The first drive member 420 can be a plate-shaped structure, a rod-shaped structure, etc.

[0078] At least two second connecting shafts 430 are connected to the first driving member 420. The at least two second connecting shafts 430 are evenly distributed along the circumference of the second annular structure 310, facilitating a more uniform application of driving force from the first driving member 420 to the second shearing assembly 300. For example, the accompanying drawings illustrate two second connecting shafts 430, which are arranged at 180° angles. For example, the number of second connecting shafts 430 can also be three, four, or the like, and this application does not impose any specific limitation thereto.

[0079] Exemplarily, the second roller 440 may be a bearing, such as a needle roller bearing, a deep groove ball bearing, or the like.

[0080] At least two second rollers 440 are rotatably connected to the second connecting shaft 430 respectively. The second rollers 440 extend into the arc groove 311 and roll in contact with the side walls of the arc groove 311, thereby reducing the friction between the second rollers 440 and the arc groove 311, reducing the force required to drive the second shearing assembly 300, and thus allowing the use of a first drive assembly 400 with a smaller size and load, further reducing the size of the shearing line device 10.

[0081] In some embodiments, the cutting line device 10 further includes a first support assembly 600 and at least one guide shaft 610. The first drive source 410 is disposed on the first support assembly 600. Exemplarily, the first support assembly 600 has at least one first guide hole, and the guide shaft 610 is connected to the first drive member 420 and is inserted into the first guide hole. Exemplarily, the first drive member 420 has at least one second guide hole, and the guide shaft 610 is connected to the first support assembly 600 and is inserted into the second guide hole. Exemplarily, the first support assembly 600 can be a plate-like structure. The first support assembly 600 can be arranged parallel to the first drive member 420.

[0082] By providing the guide shaft 610 and the first guide hole, it is easy to guide the movement of the first driving member 420, thereby improving the movement accuracy of the clamping and cutting device 10. By providing the guide shaft 610 and the second guide hole, it is easy to guide the movement of the first driving member 420, thereby improving the movement accuracy of the clamping and cutting device 10.

[0083] For example, Figure 11 As shown, the shear line device 10 also includes at least one first linear bearing 640, which is connected to the first support assembly 600 and is coaxially arranged with the first guide hole. When the guide shaft 610 passes through the first guide hole, it also passes through the first linear bearing 640 and is slidably connected to the inner ring of the first linear bearing 640.

[0084] For example, Figure 2 As shown, the shear line device 10 also includes at least one second linear bearing 650, which is connected to the first driving member 420 and is coaxially arranged with the second guide hole. When the guide shaft 610 passes through the second guide hole, it also passes through the second linear bearing 650 and is slidably connected to the inner ring of the second linear bearing 650.

[0085] By providing the first linear bearing 640 and the second linear bearing 650 , the movement accuracy of the cutting line device 10 is further improved.

[0086] In some embodiments, the cutting line device 10 further includes a follower 620 and a sensor 630. The follower 620 is connected to the second annular structure 310 and can move with the second annular structure 310. The sensor 630 is disposed on the first driving member 420 and is configured to detect the rotation angle of the follower 620.

[0087] For example, Figure 2 、 Figure 3 and Figure 13 As shown, the follower 620 may be a disc structure with a through hole in the center thereof so that the disc avoids structures such as the first annular structure 110 .

[0088] For example, Figure 13 As shown, sensor 630 may be a slot-type photoelectric sensor 631. The edge of follower 620 may have a notch 621. When notch 621 is located within the notch of the slot-type photoelectric sensor, sensor 630 may be considered to have detected that first annular structure 110 is in its zero position. The zero position of first annular structure 110 may be the position of first annular structure 110 when wire 40 is cut.

[0089] In some embodiments, the cutting line device 10 further includes a second support assembly 710 and a second drive assembly 720. The second drive assembly 720 is connected to the second support assembly 710 and is in driving connection with the first annular structure 110, and is configured to drive the first annular structure 110 to rotate.

[0090] For example, the second support assembly 710 can be integrally formed with the first support assembly 600, that is, the second support assembly 710 and the first support assembly 600 can be the same plate-shaped structure. Figure 14 As shown, the second support assembly 710 may include a first plate-like structure 711 and a third ring-like structure 712 connected to each other. The second drive assembly 720 may be connected to the first plate-like structure 711. The first ring-like structure 110 may be mounted on the third ring-like structure 712 and rotatably connected relative to the third ring-like structure 712. For example, the first plate-like structure 711 may be integrally formed with the first support assembly 600, that is, the first plate-like structure 711 and the first support assembly 600 may be the same plate-like structure.

[0091] For example, Figure 14 As shown, the shear wire device 10 further includes a first bearing 750 . The inner ring of the first bearing 750 is sleeved on the third annular structure 712 , and the first annular structure 110 is sleeved on the outer ring of the first bearing 750 .

[0092] For example, Figure 4 and Figure 14As shown, the clipping line device 10 further includes a bearing cover plate 820. The bearing cover plate 820 is connected to the second hollow shaft segment 113 and is located on a side of the first bearing 750 away from the first hollow shaft segment 112 to prevent the first bearing 750 from falling off.

[0093] In some embodiments, the cutting line device 10 further includes a driving gear 730 and a driven gear 740. The driving gear 730 is connected to the second drive assembly 720 and rotates under the drive of the second drive assembly 720. The driven gear 740 meshes with the driving gear 730 and is coaxially connected to the first annular structure 110. The driven gear 740 rotates under the drive of the driving gear 730, thereby driving the first annular structure 110 to rotate.

[0094] By providing the driving gear 730 and the driven gear 740, the axis of the output shaft of the second driving assembly 720 can be prevented from coinciding with the axis of the winding shaft 20, thereby avoiding interference between the second driving assembly 720 and the winding shaft 20. In addition, by providing the gears of the driving gear 730 and the driven gear 740, a reasonable reduction ratio can also be set to achieve a reduction effect.

[0095] An embodiment of the present application also provides a winding device. Figure 15 The figure shows a schematic diagram of the structure of the winding device provided by an embodiment of the present application. Figure 15 As shown, the winding apparatus 1 includes a support 30, a winding shaft 20, and the wire-gripping and cutting device 10 of the above-described embodiment. The winding shaft 20 is rotatably connected to the support 30. The winding shaft 20 rotates to wind a wire 40 into a coil 50. The wire-gripping and cutting device 10 is configured to grip and cut the portion of the wire 40 connected to the coil 50. The winding shaft 20 can be inserted into the first annular structure 110 of the wire-gripping and cutting device 10.

[0096] Since the winding equipment 1 includes the wire clamping and cutting device 10 mentioned in the above embodiment, the winding equipment 1 has all the technical features and technical effects of the wire clamping and cutting device 10, which will not be repeated here.
