Description

Technical Field

[0001] This invention belongs to the field of motor parts manufacturing technology, and particularly relates to a waste-free stator winding clamping fixture and stator winding device. Background Technology

[0002] The coils wound and connected in a specific pattern in the armature of an electric motor are called the stator windings. They are one of the main components of the motor that realizes electromechanical energy conversion. The coils that make up the armature windings can be single-turn or multi-turn, and each turn can be made up of several parallel wires. The part of the coil embedded in the slot is called the effective part, and the part extending out of the slot is called the connecting end, or simply the end.

[0003] The traditional stator winding process is performed by specific equipment called a stator winding machine. The clamping part of the winding machine includes a fixture for mounting the iron core and a wire clamping structure for guiding the copper wire.

[0004] like Figure 11 As shown, copper wire 1 is guided and attached to iron core 2 by a guide clamping structure. An external drive mechanism drives the fixture to rotate so that the copper wire is wound around the iron core. In order to keep the copper wire taut at all times, the wire clamping mechanism 3 in the prior art is generally provided with a bent end 4 away from the iron core. After the copper wire passes through the bent end 4, it can be kept taut, which can prevent the wire group from loosening and affecting the magnetic field effect. However, such a structure causes the copper wire at the bent end to become waste after the winding is completed, resulting in serious waste of materials, which is inconsistent with the company's sustainable development concept and is detrimental to the company's development. Summary of the Invention

[0005] The purpose of this invention is to provide a waste-free stator winding clamping fixture and stator winding device, which aims to solve the technical problem in the existing stator winding mechanism where the copper wire at the bending part becomes waste material after winding, resulting in serious material waste, which is inconsistent with the concept of sustainable development of enterprises and is detrimental to enterprise development.

[0006] To achieve the above objectives, this invention provides a waste-free stator winding clamping fixture, comprising a mounting base and a clamping mechanism. The mounting base is provided with an iron core fixture; the clamping mechanism is provided with an opening and closing groove. When it is necessary to wind copper wire onto the iron core of the iron core fixture, the clamping mechanism clamps the end of the copper wire through the opening and closing groove, and the mounting base rotates to wind the copper wire onto the iron core. After winding is completed, the opening and closing groove releases the end of the wire, and the clamping mechanism clamps the tail portion of the copper wire through the opening and closing groove.

[0007] Optionally, the wire clamping mechanism is disposed on the side wall of the mounting base, and when the mounting base is driven to rotate by an external driving mechanism, the wire clamping mechanism rotates synchronously with the mounting base.

[0008] Optionally, the wire clamping mechanism includes a fixed base, a rotating base, and a clamp; the rotating base is rotatably connected to the fixed base; the clamp is slidably connected to the rotating base; the pushing component is used to drive the clamp to move closer to or away from the copper wire; wherein, the opening and closing groove is formed on the clamp, and when the pushing component drives the clamp to move towards the copper wire, the opening and closing groove opens; when the pushing component drives the clamp away from the copper wire, the opening and closing groove closes, clamping the copper wire.

[0009] Optionally, the rotating seat includes a rotating sleeve and a wire block. The rotating sleeve is rotatably connected to the fixed seat and can rotate on its own axis. The wire block is disposed on the rotating sleeve. The clamp is slidably connected to the inner ring of the rotating sleeve and can slide along the length direction of the inner ring. The wire block is provided with a wire groove, which is aligned with the opening and closing groove.

[0010] Optionally, the fixed base is provided with a reset component, which is used to adjust the orientation of the rotating base; when the chuck needs to clamp the wire tail, the reset component drives the rotating base to rotate so that the length direction of the opening and closing groove is the same as the length direction of the copper wire.

[0011] Optionally, the reset assembly includes a first magnetic element and a second magnetic element. The first magnetic element is disposed on the side wall of the rotating base; the second magnetic element is disposed on the fixed base and located on one side of the rotating base; the ends of the first magnetic element and the second magnetic element that are opposite to each other have opposite magnetic poles.

[0012] Optionally, the pushing assembly includes a swing arm, an elastic element, and an abutment block. The swing arm is rotatably connected to the rotating seat. The elastic element is disposed within the rotating seat. The abutment block is fixedly disposed on the outer side wall of the chuck. One end of the swing arm abuts against the end of the chuck away from the opening and closing groove. Both ends of the elastic element abut against or are fixedly connected to the abutment block and the inner wall of the rotating seat, respectively. An external driving mechanism can drive the other end of the swing arm to rotate and move, so that the end of the swing arm drives the chuck to move against the elastic force of the elastic element.

[0013] Optionally, the chuck includes a slide rod and an elastic conical head, the slide rod being slidably connected to a rotating seat; the elastic conical head is disposed on the slide rod; the opening and closing groove is formed on the elastic conical head, and the rotating seat is provided with a guide conical surface; when the slide rod moves away from the copper wire, the elastic conical head is guided and driven by the guide conical surface, and the opening and closing groove contracts; when the slide rod moves towards the copper wire, the elastic conical head resets, and the opening and closing groove expands.

[0014] Optionally, the slide rod and / or the elastic conical head are provided with a conical guide groove communicating with the opening and closing groove, and the rotating seat is provided with an abutment rod, which is located in the conical guide groove; when the slide rod approaches the copper wire, the abutment rod abuts against the inner wall of the narrow end of the conical guide groove, so that the opening and closing groove expands to a width that can accommodate the copper wire.

[0015] The above-mentioned technical solutions of one or more of the waste-free stator winding clamping fixtures provided in this invention embodiment have at least one of the following technical effects: After the clamping mechanism clamps the wire end, it rotates to one side of the mounting base, so that the copper wire abuts against and fits against the iron core wire groove set on the iron core fixture. During the winding process, the height of the clamping mechanism and the mounting base are adapted to each other, so that the copper wire can be smoothly wound in each wire groove. After the winding is completed, the clamping mechanism releases the wire end and then clamps the copper wire segment between the iron core and the copper wire conveying mechanism. Then, the cutting mechanism cuts the copper wire, completing the single-group iron core winding process. In this process, after the cutting mechanism finishes cutting the wire, the part between the iron core and the copper wire conveying mechanism clamped by the clamping mechanism automatically becomes a new wire end, and the part connecting the iron core winding group automatically becomes the wire tail. No waste wire is generated, which effectively achieves the effect of saving copper wire material, prevents wire waste, reduces winding cost, conforms to the concept of sustainable development of enterprises, and is conducive to enterprise development.

[0016] To achieve the above objectives, an embodiment of the present invention provides a stator winding device, including the aforementioned waste-free stator winding clamping fixture.

The following description is based on the accompanying drawings. Figures 1-10 The described embodiments are exemplary and intended to explain embodiments of the invention, and should not be construed as limiting the invention.

Therefore, they should not be construed as limitations on the present invention.

[0040] Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of embodiments of the present invention, "a plurality of" means two or more, unless otherwise explicitly specified.

[0041] In the embodiments of the present invention, unless otherwise explicitly specified and limited, the terms "installation," "connection," "linking," "fixing," etc., should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components. Those skilled in the art can understand the specific meaning of the above terms in the embodiments of the present invention according to the specific circumstances.

[0042] In one embodiment of the present invention, such as Figures 1-10 As shown, a stator winding device is provided, including a base, a waste-free stator winding clamping fixture, a copper wire conveying mechanism, a rotating mechanism, a positioning linear module, and a wire cutting mechanism. The rotating mechanism is mounted on the base, the waste-free stator winding clamping fixture is mounted on the rotating mechanism, the copper wire conveying mechanism is located on one side of the waste-free stator winding clamping fixture, and the output end of the positioning linear module is drivenly connected to the clamping end of the waste-free stator winding clamping fixture.

[0043] A waste-free stator winding clamping fixture includes a mounting base 100 and a wire clamping mechanism 200. The mounting base 100 is equipped with an iron core fixture. The wire clamping mechanism 200 is provided with an opening and closing groove 300. When it is necessary to wind copper wire onto the iron core of the iron core fixture, the wire clamping mechanism 200 clamps the end of the copper wire through the opening and closing groove 300, and the mounting base 100 rotates to wind the copper wire onto the iron core. After winding, the opening and closing groove 300 releases the end of the wire, and the wire clamping mechanism 200 clamps the tail portion of the copper wire through the opening and closing groove 300. In this embodiment, the mounting base 100 is mounted on a rotating mechanism, and the wire clamping mechanism 200 is driven by an external driving mechanism to revolve around the mounting base 100.

[0044] Specifically, the working principle of this stator winding device is as follows:

[0045] Core installation: Install the core to be wound onto the core fixture;

[0046] Wire feeding: The copper wire at the output end of the copper wire conveying mechanism is clamped by the wire clamping mechanism 200 through the opening and closing groove 300. After clamping, the wire clamping mechanism 200 moves through the external drive mechanism or rotates with the mounting base 100 to the other side of the mounting base 100, so that the copper wire between the copper wire conveying mechanism and the wire clamping mechanism 200 is attached to the wire groove of the iron core.

[0047] Winding: The rotating mechanism drives the mounting base 100 to rotate. During the rotation of the mounting base 100, the wire clamping mechanism 200 rotates together with the mounting base 100. The copper wire output by the copper wire conveying mechanism is wound on the iron core along the direction of the wire groove on the iron core.

[0048] Wire cutting: After winding a preset number of turns, the opening and closing groove 300 on the wire clamping mechanism 200 releases the end of the copper wire. The positioning linear module drives the wire clamping mechanism 200 to move between the copper wire conveying mechanism and the iron core. The opening and closing groove 300 of the wire clamping mechanism 200 closes to clamp the copper wire. The wire cutting mechanism cuts the copper wire between the opening and closing groove 300 and the iron core.

[0049] In this process, after the wire cutting mechanism finishes cutting the wire, the part between the iron core and the copper wire conveying mechanism that is clamped by the wire clamping mechanism 200 automatically becomes a new wire head, and the part connected to the iron core winding group automatically becomes a wire tail. No waste wire is generated, which effectively achieves the effect of saving copper wire materials, prevents wire waste, reduces the cost of winding wire, conforms to the company's sustainable development concept, and is conducive to the company's development.

[0050] like Figures 1-10As shown, the wire clamping mechanism 200 is further disposed on the side wall of the mounting base 100. When the mounting base 100 is driven to rotate by an external drive mechanism, the wire clamping mechanism 200 rotates synchronously with the mounting base 100. Specifically, in this embodiment, the wire clamping mechanism 200 is threadedly connected to the side wall of the mounting base 100, and the iron core fixture is mounted on the top of the mounting base 100. When the mounting base 100 rotates, the wire clamping mechanism 200 rotates around the iron core fixture along with the mounting base 100. The structure is simple and easy to manufacture. In other embodiments, the installation method of the wire clamping mechanism 200 is flexible. If the installation environment allows, an additional drive mechanism can be provided to drive the wire clamping mechanism 200 to perform a constant-speed revolution around the iron core fixture.

[0051] like Figures 1-10 As shown, the wire clamping mechanism 200 further includes a fixed base 210, a rotating base 220, and a clamp 230; the rotating base 220 is rotatably connected to the fixed base 210; the clamp 230 is slidably connected to the rotating base 220; the pushing component 400 is used to drive the clamp 230 to approach or move away from the copper wire. Specifically, in this embodiment, the fixed base 210 is provided with a first mounting hole, the length of which is perpendicular to the base; the rotating base 220 is rotatably connected to the first mounting hole; the rotating base 220 is provided with a second mounting hole; the clamp 230 can slide up and down in the vertical direction and is connected to the second mounting hole; the opening groove 300 is formed on the top of the clamp 230; the top of the clamp 230 is always located at the top opening position of the second mounting hole.

[0052] The opening and closing groove 300 is formed on the clamp 230. When the pushing component 400 drives the clamp 230 to move towards the copper wire, the opening and closing groove 300 opens; when the pushing component 400 drives the clamp 230 away from the copper wire, the opening and closing groove 300 tightens, clamping the copper wire. In this embodiment, the clamp 230 is an elastic clamp 230. The elastic clamp 230 structure utilizes its own elastic structure to enable the opening and closing groove 300 to open and close automatically. The structure is simple and easy to install, effectively improving the structural simplicity of the wire clamping mechanism 200. A top block 600 is provided inside the opening and closing groove 300 to abut the bottom of the copper wire to prevent the copper wire from deviating.

[0053] The rotating seat 220 and the fixed seat 210 are connected by a rotating structure. When the clamp 230 clamps the wire end and the wire clamping mechanism 200 revolves, the rotating seat 220 can rotate on its own axis during the revolution, so that the orientation of the wire end is always set in the same direction as the copper wire output by the copper wire conveying mechanism, thus preventing the copper wire from bending and being damaged.

[0054] Furthermore, the rotating base 220 includes a rotating sleeve 221 and a wire block 222. The rotating sleeve 221 is rotatably connected to the fixed base 210 and can rotate on its own. The wire block 222 is disposed on the rotating sleeve 221. A second mounting hole is formed in the inner ring of the rotating sleeve 221, and the clamp 230 is slidably connected to the inner ring of the rotating sleeve 221 and can slide along the length direction of the inner ring. The wire block 222 is provided with a wire groove 223, which is aligned with the opening and closing groove 300. Specifically, in this embodiment, the wire groove 223 is a conical groove, and the narrow end of the conical groove is connected to the input port of the wire groove 223. When the copper wire is output to the wire groove 223 through the copper wire conveying mechanism, based on the rigidity of the copper wire itself, the copper wire will be guided by the conical inner wall and smoothly enter the opening and closing groove 300 through the output port of the wire groove 223. It is worth noting that the opening and closing groove 300 is in an open state when the wire is fed in.

[0055] like Figures 1-10 As shown, further, a reset component 211 is provided on the fixed base 210. The reset component 211 is used to adjust the orientation of the rotating base 220. When the chuck 230 needs to clamp the wire tail, the reset component 211 drives the rotating base 220 to rotate, so that the length direction of the opening and closing groove 300 is the same as the length direction of the copper wire. Since the rotating base 220 rotates during the revolution of the wire clamping mechanism 200, after the wire winding is completed, the opening and closing groove 300 on the chuck 230 may deviate from the direction of the copper wire output by the copper wire conveying mechanism. Even with the wire guide groove 223, it may not be possible to smoothly introduce the copper wire into the opening and closing groove 300. Therefore, the reset component 211 can ensure that the orientation of the opening and closing groove 300 is consistent with the direction of the copper wire output by the copper wire conveying mechanism each time the wire is fed, thereby ensuring the smoothness of the wire feeding and improving production efficiency.

[0056] like Figures 1-10 As shown, further, the reset assembly 211 includes a first magnetic element 212 and a second magnetic element 213. The first magnetic element 212 is disposed on the side wall of the rotating base 220; the second magnetic element 213 is disposed on the fixed base 210 and located on one side of the rotating base 220; the ends of the first magnetic element 212 and the second magnetic element 213 are opposite magnetic poles. Specifically, in this embodiment, both the first magnetic element 212 and the second magnetic element 213 are rare earth magnets. In other embodiments, the first magnetic element 212 and the second magnetic element 213 can be electromagnetic coils.

[0057] In this embodiment, there are two sets of second magnetic components 213, which are symmetrically arranged on both sides of the rotating seat 220 to increase the magnetic attraction probability of the first magnetic component 212 and the second magnetic component 213 and improve the reset accuracy.

[0058] like Figures 1-10As shown, the pushing assembly 400 further includes a swing arm 410, an elastic element 420, and an abutment block 430. The swing arm 410 is rotatably connected to the rotating seat 220; the elastic element 420 is disposed inside the rotating seat 220; the abutment block 430 is fixedly disposed on the outer side wall of the chuck 230; one end of the swing arm 410 abuts against the end of the chuck 230 away from the groove 300; both ends of the elastic element 420 abut against or are fixedly connected to the abutment block 430 and the inner wall of the rotating seat 220, respectively; an external driving mechanism can drive the other end of the swing arm 410 to rotate and move, so that the end of the swing arm 410 drives the chuck 230 to move against the elastic force of the elastic element 420. Specifically, in this embodiment, the bottom of the rotating seat 220 is provided with a mounting groove, and the swing arm 410 is rotatably connected to the side wall of the mounting groove. The rotation path of one free end of the swing arm 410 passes through the bottom of the chuck 230. Therefore, when the free end of the swing arm 410 rotates, it can push the bottom of the chuck 230, and the chuck 230 slides in the vertical direction under the action of the swing arm 410.

[0059] In this embodiment, the bottom of the chuck 230 is not connected to the swing arm 410. The swing arm 410 pushes against the bottom of the chuck 230 during rotation to generate a pushing effect. In other embodiments, the swing arm 410 and the bottom of the chuck 230 can be rotatably connected, with the swing arm 410 always connected to the bottom of the chuck 230. The elastic element 420 is a spring, which can be a compression spring that always drives the chuck 230 to slide downwards, or a tension spring whose two ends are fixedly connected to the rotating seat 220 and the abutment block 430, and which always drives the chuck 230 to slide upwards. The external drive mechanism drives the swing arm 410 to perform adaptive rotation drive according to the type of elastic element 420.

[0060] In this embodiment, a reinforcing member 440 is provided at the end of the swing arm 410 away from the chuck 230. The reinforcing member 440 is used to drive the swing arm 410 to rotate and move in a preset direction to ensure the stability of the swing arm in the free state. The reinforcing member 440 is a spring.

[0061] like Figures 1-10 As shown, the chuck 230 further includes a slide rod 231 and an elastic conical head 232. The slide rod 231 is slidably connected to the rotating seat 220; the elastic conical head 232 is disposed on the slide rod 231; the opening and closing groove 300 is formed on the elastic conical head 232, and the rotating seat 220 is provided with a guide conical surface 224; when the slide rod 231 moves away from the copper wire, the elastic conical head 232 is guided and driven by the guide conical surface 224, and the opening and closing groove 300 contracts; when the slide rod 231 moves towards the copper wire, the elastic conical head 232 resets, and the opening and closing groove 300 expands. Specifically, in this embodiment, the elastic conical head 232 is an elastic gripper, and the fingers of the gripper are open in their natural state to open the opening and closing groove 300.

[0062] The elastic conical head 232 has a flexible structure. In other embodiments, the elastic conical head 232 may include two sets of movable inserts. The inserts are provided with limiting grooves for limiting copper wires. A gap is provided between the two sets of inserts, and the opening and closing groove 300 is formed in the gap.

[0063] like Figures 1-10 As shown, further, the slide rod 231 is provided with a conical guide groove 233 that connects to the opening and closing groove 300, and the rotating seat 220 is provided with an abutment rod 225, which is located inside the conical guide groove 233; the opening and closing groove 300 passes through the elastic conical head 232 and connects to the conical guide groove 233; when the slide rod 231 approaches the copper wire, the abutment rod 225 abuts against the inner wall of the narrow end of the conical guide groove 233, causing the opening and closing groove 300 to expand to a width that can accommodate the copper wire. In other embodiments, the conical guide groove 233 can be provided on the elastic conical head 232, or the two ends of the conical guide groove 233 can be formed on the elastic conical head 232 and the slide rod 231, respectively.

[0064] like Figures 1-10 As shown, further, the lead block is provided with a spring-loaded assembly 500 to enhance the reset effect of the chuck 230. The spring-loaded assembly includes a drive spring 510, a first connecting block 520, and a second connecting block 530. A slide groove 540 is provided on the side wall of the lead block. The first connecting block 520 is formed at one end of the slide groove 540, and the second connecting block 530 is fixedly disposed on the side wall of the chuck 230, located at the bottom of the slide groove 540. The drive spring 510 is movably connected within the slide groove 540, and its two ends abut or are fixedly connected to the first connecting block 520 and the second connecting block 530, respectively. The drive spring 510 is a compression spring. When it is necessary to drive the chuck 230 to move downward, the drive spring 510 drives the chuck 230 to move in a preset direction through the first connecting block 520 and the second connecting block 530, further improving the reset efficiency of the chuck 230. Specifically, the second connecting block 530 is disposed on the side wall of the elastic conical head 232.

[0065] The above are merely preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
