Description

Technical Field

[0001] This utility model relates to the field of motor stator production equipment, specifically to an automatic motor stator winding device. Background Technology

[0002] The stator winding process is one of the core steps in motor production, and its quality directly affects the motor's electromagnetic performance, efficiency, temperature rise characteristics, and service life. With the continuous development of automation technology, automatic stator winding equipment has gradually become the industry mainstream. Through the synergy of mechanical structure and control system, it achieves high-precision and high-efficiency winding of copper wire in the stator teeth.

[0003] Currently, mainstream automatic stator winding equipment for motors typically employs a multi-degree-of-freedom motion mechanism. Its core component is the winding head—this component, driven by a servo motor and threaded with copper wire, achieves reciprocating up-and-down and left-and-right translational movements relative to the stator teeth, thus winding the copper wire along a preset path. While this type of equipment significantly improves winding efficiency, it still suffers from a key technical deficiency: the lack of an effective copper wire guiding structure. During the winding process, the copper wire needs to maintain precise tension and trajectory control at high speeds. However, existing equipment relies solely on the mechanical movement and positioning of the winding head, without an independent guiding module to dynamically constrain the copper wire. This leads to insufficient winding accuracy, and the copper wire is prone to deviation due to inertia or external disturbances (such as airflow or vibration), potentially accidentally catching on adjacent teeth, causing short circuits or interlayer insulation failure.

[0004] In view of the above-mentioned problems of existing winding equipment, it is necessary to develop an automatic winding device for motor stators to improve winding accuracy and ensure winding quality. Utility Model Content

[0005] (a) Technical problems to be solved This invention provides an automatic winding device for motor stators, which can at least solve the technical problem of how to improve winding accuracy.

[0006] (II) Technical Solution To solve the above-mentioned technical problems, this utility model provides the following technical solution: an automatic winding device for motor stator, comprising: frame; The indexing plate, wire nozzle, and wire nozzle drive mechanism are all mounted on the frame. The indexing plate is used to load and drive the stator to rotate around its own axis by a preset angle so that the target stator slot of the stator is aligned with the wire nozzle. The wire nozzle is provided with a wire hole for copper wire to pass through. The wire nozzle drive mechanism is connected to the wire nozzle drive and is used to drive the wire nozzle to move relative to the target stator slot. The guiding mechanism is located on the frame and has a guiding channel. The guiding channel is opposite to and connected to the target stator slot. The guiding mechanism is used to press the stator tightly onto the indexing plate and guide the copper wire on the wire nozzle into the target stator slot along the guiding channel.

[0007] Further, the aforementioned guidance mechanisms include: Two symmetrically arranged upper pressure arms and two symmetrically arranged lower pressure arms are respectively located above and below the indexing plate. An upper wire passage for copper wires to pass through is provided between the two upper pressure arms, and a lower wire passage for copper wires to pass through is provided between the two lower pressure arms. The upper wire passage and the lower wire passage are combined to form a guide channel. Both the upper pressure arm drive assembly and the lower pressure arm drive assembly are mounted on the frame. The upper pressure arm drive assembly is connected to the upper pressure arm and is used to drive the upper pressure arm to move relative to the stator on the indexing plate, so that the upper pressure arm presses tightly against the top of the stator and aligns the upper wire passage with the target stator slot. The lower pressure arm drive assembly is connected to the lower pressure arm and is used to drive the lower pressure arm to move relative to the stator on the indexing plate, so that the lower pressure arm presses tightly against the bottom of the stator and aligns the lower wire passage with the target stator slot.

[0008] Furthermore, the two upper pressure arms facing each other and the two lower pressure arms facing each other are smoothly transitioned.

[0009] Furthermore, the aforementioned indexing plate has a through hole on its axis, and the guiding mechanism also includes: The guide block is movably installed in the through hole. The top of the guide block has a guide groove. The outer side of the guide block is a smooth arc-shaped surface, and its diameter is not greater than the inner diameter of the stator. The guide block drive is mounted on the frame and is connected to the guide block for transmission. The guide block drive is used to drive the guide block to move towards or away from the target stator slot so that the outer side of the guide block abuts against the inner side of the stator and the guide slot is aligned with the target stator slot, thereby forming a guide channel together with the upper wire passage and the lower wire passage.

[0010] Furthermore, the cross-section of the aforementioned guide block is arc-shaped, and the outer diameter of the guide block is equal to the inner diameter of the stator.

[0011] Furthermore, the aforementioned guide block is also provided with a clearance channel, which is connected to the guide groove and is used for the wire nozzle to pass through.

[0012] Furthermore, the aforementioned automatic winding device for motor stator also includes a wire cutting mechanism, which is mounted on the frame and used to cut copper wire. The upper pressure arm drive assembly, the lower pressure arm drive assembly, the guide block drive component, the indexing plate, and the wire cutting mechanism are arranged laterally on the same straight line. The wire nozzle drive mechanism, the upper pressure arm drive assembly, and the lower pressure arm drive assembly all include a connected lateral drive component and a lifting drive component. The lateral drive component is used to drive the wire nozzle, the upper pressure arm, or the lower pressure arm to move laterally, and the lifting drive component is used to drive the wire nozzle, the upper pressure arm, or the lower pressure arm to move vertically.

[0013] In a further configuration, the aforementioned wire-cutting mechanism includes a wire-cutting base, a wire-cutting finger, and a wire-cutting drive. The wire-cutting base and / or the wire-cutting finger are equipped with a cutter. The wire-cutting drive is mounted on a frame and is connected to the wire-cutting base and / or the wire-cutting finger for transmission. The wire-cutting drive is used to drive the wire-cutting base and the wire-cutting finger to move towards or away from each other in order to cut the copper wire located between the wire-cutting base and the wire-cutting finger.

[0014] (III) Beneficial Effects Compared with the prior art, the automatic winding device for motor stator provided by this utility model has the following advantages: When using the automatic stator winding device for motors provided by this utility model, firstly, the motor stator is mounted on the indexing plate, and the stator slots on both sides of the teeth to be wound are respectively set as the first target stator slot and the second target stator slot, and the first target stator slot is aligned with the wire nozzle; then, the starting end of the copper wire is passed through the wire hole and fixed in the preset position on the frame, while the guide mechanism presses the stator tightly; next, the wire nozzle driving mechanism drives the wire nozzle to move towards the first target stator slot, driving the copper wire to enter from top to bottom along the guide channel and pass through the first target stator slot; completing the single-sided winding. After the wire is wound, the guide mechanism releases the stator, while the indexing plate drives the stator to rotate around its own axis by a preset angle, aligning the second target stator slot with the wire nozzle. Next, the guide mechanism presses the stator firmly again, and the wire nozzle drive mechanism drives the wire nozzle towards the second target stator slot, causing the copper wire to enter and pass through the second target stator slot from bottom to top along the guide channel. Then, the guide mechanism releases the stator again, while the indexing plate drives the stator to rotate in the opposite direction around its own axis to reset, aligning the first target stator slot with the wire nozzle again, thus winding the copper wire on the teeth to form the first layer of closed winding. This process is repeated continuously, achieving multi-layer uniform winding of the copper wire along the length of the teeth. As can be seen, this utility model can automatically wind copper wire onto the teeth of the stator by using a wire nozzle, a wire nozzle drive mechanism, and an indexing plate. The guide mechanism can not only position the stator and prevent the target stator slot from vibrating and shifting during the winding process, but also, in conjunction with the indexing plate, accurately achieve physical constraints on the copper wire winding path, eliminating the risk of copper wire shifting or getting caught on adjacent teeth, thereby effectively improving winding accuracy and ensuring winding quality.

[0017] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0018] This invention provides an automatic winding device for motor stators, which addresses the problem of improving winding accuracy.

[0019] See Figure 1 and Figure 2 As shown, Figure 1 This is a perspective view of the automatic stator winding device in the embodiment. Figure 2 for Figure 1 The enlarged schematic diagram at point A shows that the automatic stator winding device for the motor includes a frame 1, an indexing plate 2, a wire nozzle 3, a wire nozzle drive mechanism 4, and a guide mechanism 5.

[0020] Both the indexing plate 2 and the wire nozzle drive mechanism 4 are mounted on the frame 1 by screwing or welding. The indexing plate 2 is used to load and drive the stator 6 to rotate around its own axis by a preset angle so that the target stator slot of the stator 6 is aligned with the wire nozzle 3. The wire nozzle 3 has a wire hole 31 for copper wire to pass through. The wire nozzle drive mechanism 4 is connected to the wire nozzle 3 and is used to drive the wire nozzle 3 to move relative to the target stator slot 6.

[0021] The guide mechanism 5 is mounted on the frame 1 and has a guide channel 51. The guide channel 51 is opposite to and connected to the target stator 6 slot. The guide mechanism 5 is used to press the stator 6 tightly onto the indexing plate 2 and guide the copper wire on the wire nozzle 3 into the target stator 6 slot along the guide channel 51.

[0022] When using the automatic stator winding device of the above technical solution, firstly, the motor stator 6 is mounted on the indexing plate 2. The two stator slots on both sides of the teeth 61 to be wound on the stator 6 are respectively set as the first target stator slot 62 and the second target stator slot 63, and the first target stator slot 62 is aligned with the wire nozzle 3. Figure 2 As shown. Then, the starting end of the copper wire is passed through the wire hole 31 and fixed in a preset position on the frame 1, while the guide mechanism 5 presses the stator 6 tightly. Next, the wire nozzle drive mechanism 4 drives the wire nozzle 3 towards the first target stator slot 62, causing the copper wire to enter from top to bottom along the guide channel 51 and pass through the first target stator slot 62. After completing the single-sided wire threading, the guide mechanism 5 releases the stator 6, while the indexing plate 2 drives the stator 6 to rotate around its own axis by a preset angle, aligning the second target stator slot 63 with the wire nozzle 3. Next, the guide mechanism 5 presses the stator 6 tightly again, and the wire nozzle drive mechanism 4 drives the wire nozzle 3 towards the second target stator slot 63, causing the copper wire to enter from bottom to top along the guide channel 51 and pass through the second target stator slot 63. Then, the guide mechanism 5 releases the stator 6 again, while the indexing plate 2 drives the stator 6 to rotate in the opposite direction around its own axis to reset, aligning the first target stator slot 62 with the wire nozzle 3 again, thus allowing the copper wire to be wound on the winding teeth 61 to form the first layer of closed winding. This process is repeated continuously, achieving multi-layered uniform winding of the copper wire along the length of the teeth. It can be seen that this invention, through the cooperation of the wire nozzle 3, the wire nozzle drive mechanism 4, and the indexing plate 2, can automatically wind the copper wire onto the teeth of the stator 6. The guide mechanism 5 not only positions the stator 6, preventing vibration-induced displacement of the target stator 6 slot during winding, but also, in conjunction with the indexing plate 2, precisely constrains the physical path of the copper wire winding, eliminating the risk of copper wire misalignment or snagging on adjacent teeth, thereby effectively improving winding accuracy and ensuring winding quality.

[0023] The aforementioned indexing plate 2 can use an existing indexing plate.

[0024] See Figure 1 , Figure 2 and Figure 3 As shown, Figure 3This is a schematic diagram of the indexing plate and guiding mechanism in one embodiment. The guiding mechanism 5 includes an upper pressure arm 52, a lower pressure arm 53, an upper pressure arm drive assembly 54, and a lower pressure arm drive assembly 55. The upper pressure arm 52 and the lower pressure arm 53 are located above and below the indexing plate 2, respectively. There are two upper pressure arms 52 and two lower pressure arms 53, symmetrically arranged. An upper wire-passing channel 511 for copper wires to pass through is provided between the two upper pressure arms 52. A lower wire-passing channel 512 for copper wires to pass through is provided between the two lower pressure arms 53. The upper wire-passing channel 511 and the lower wire-passing channel 512 combine to form a guiding channel 51. The upper pressure arm drive assembly 54 and the lower pressure arm drive assembly 55 are both mounted on the frame 1 by screwing or welding. The upper pressure arm drive assembly 54 is driven by the upper pressure arm 52 and is used to drive the upper pressure arm 52 to move relative to the stator 6 on the indexing plate 2, so that the upper pressure arm 52 presses tightly against the top of the stator 6 and aligns the upper wire passage 511 with the target stator 6 slot. The lower pressure arm drive assembly 55 is driven by the lower pressure arm 53 and is used to drive the lower pressure arm 53 to move relative to the stator 6 on the indexing plate 2, so that the lower pressure arm 53 presses tightly against the bottom of the stator 6 and aligns the lower wire passage 512 with the target stator 6 slot. In this way, the guide mechanism 5, through the symmetrical pressing design of the upper and lower pressure arms 53, achieves the positioning of the stator 6 during the winding process and avoids the positional displacement of the target stator 6 slot due to vibration. In addition, while positioning, the guide mechanism 5, through the upper and lower pressure arms 53, can also block the stator 6 slot adjacent to the target stator 6 slot, effectively preventing the copper wire from shifting or getting caught on adjacent teeth, further improving the winding accuracy of this invention.

[0025] See Figure 1 , Figure 2 and Figure 3 As shown, based on the above-described guide mechanism 5 embodiment, the two upper pressure arms 52 facing each other and the two lower pressure arms 53 facing each other both have a smooth transition. This smooth transition structure can greatly reduce frictional damage when the copper wire contacts the upper and lower pressure arms 53.

[0026] See Figure 1 , Figure 2 and Figure 3As shown, based on the above-described embodiment of the guide mechanism 5, the indexing plate 2 has a through hole 21 on its axis. The guide mechanism 5 also includes a guide block 56 and a guide block drive member 57. The guide block 56 is movably located within the through hole 21, and a guide groove 513 is formed at the top of the guide block 56. The outer surface of the guide block 56 is a smooth arc-shaped surface, and its diameter is not greater than the inner diameter of the stator 6. The guide block drive member 57 is mounted on the frame 1 by means of screwing or welding, and is connected to the guide block 56 in a transmission manner. The guide block drive member 57 is used to drive the guide block 56 to move towards or away from the target stator 6 groove, so that the outer surface of the guide block 56 abuts against the inner surface of the stator 6, and the guide groove 513 is aligned with the target stator 6 groove, thereby forming a guide channel 51 together with the upper wire passage 511 and the lower wire passage 512. Thus, the smooth outer surface of the guide block 56 always abuts against the stator 6 during the winding process, which not only restricts the radial position of the stator 6 but also further constrains the movement trajectory of the copper wire, thereby further improving the winding accuracy of this invention. In addition, the smooth outer surface can also reduce the friction between the guide block 56 and the stator 6, effectively preventing the stator 6 from being scratched by the guide block 56 during rotation.

[0027] The aforementioned guide block drive component 57 can use existing linear drive mechanisms such as telescopic cylinders or telescopic poles, and its output end is connected to the guide block 56 by means of screwing or welding.

[0028] See Figure 2 As shown, based on the above embodiment of guide block 56, the cross-section of guide block 56 is arc-shaped, and the outer diameter of guide block 56 is equal to the inner diameter of stator 6. Thus, when guide block 56 abuts against stator 6, the outer surface of guide block 56 contacts the inner surface of stator 6, thereby eliminating the gap between them, preventing copper wire from getting stuck in the gap, and enhancing the radial stability of stator 6 during the winding process.

[0029] See Figure 3 As shown, based on the above embodiment of guide block 56, guide block 56 also has a clearance channel 561. The clearance channel 561 is connected to guide groove 513 and is used for wire nozzle 3 to pass through. In this way, clearance channel 561 provides movement space for wire nozzle 3, so that wire nozzle 3 can drive copper wire into the target stator 6 slot for winding, thereby improving winding density and interlayer uniformity.

[0030] See Figure 1As shown, based on any of the above embodiments, the automatic winding device for the motor stator further includes a wire cutting mechanism 7. The wire cutting mechanism 7 is mounted on the frame 1 and is used to cut copper wire. The upper pressure arm drive assembly 54, the lower pressure arm drive assembly 55, the guide block drive component 57, the indexing plate 2, and the wire cutting mechanism 7 are arranged laterally on the same straight line. The wire nozzle drive mechanism 4, the upper pressure arm drive assembly 54, and the lower pressure arm drive assembly 55 each include a connected lateral drive component 8 and a lifting drive component 9. The lateral drive component 8 is used to drive the wire nozzle 3, the upper pressure arm 52, or the lower pressure arm 53 to move laterally. The lifting drive component 9 is used to drive the wire nozzle 3, the upper pressure arm 52, or the lower pressure arm 53 to move vertically. Thus, the wire cutting mechanism 7 achieves an automated closed loop in the winding process, reducing manual intervention and improving production efficiency; while the lateral arrangement design eliminates the need for a longitudinal drive mechanism, optimizing equipment space and saving drive costs.

[0031] The aforementioned lateral drive component 8 can use existing linear motor modules or servo motor-screw nut linear modules and other linear drive mechanisms. The aforementioned lifting drive component 9 can use existing telescopic cylinders or telescopic poles and other linear drive mechanisms. One of the lateral drive component 8 and the lifting drive component 9 is mounted on the frame 1 by means of screwing or welding, and the output end of the other is connected to the wire nozzle 3, the upper pressure arm 52 or the lower pressure arm 53 by means of screwing or welding.

[0032] See Figure 1 As shown, based on the above-described transverse arrangement embodiment, the wire nozzle drive mechanism 4 may further include a flip drive assembly 41. The flip drive assembly 41 is used to drive the wire nozzle 3 to flip longitudinally. In this way, the flip drive assembly 41 can work in conjunction with the transverse drive member 8 and the lifting drive member 9 to adapt to different winding patterns (such as overlapping winding and wave winding), thus expanding the application range of the equipment.

[0033] The aforementioned flip drive assembly 41 can use existing rotary motors or telescopic motor-crank connecting rod assemblies and other rotary drive mechanisms.

[0034] See Figure 1 As shown, in one embodiment of the positioning fixture 2, the wire cutting mechanism 7 includes a wire cutting base 71, wire cutting fingers 72, and a wire cutting drive 73. A cutter 74 is provided on the wire cutting base 71 and / or the wire cutting fingers 72 via screwing or welding. The wire cutting drive 73 is mounted on the frame 1 via screwing or welding and is drively connected to the wire cutting base 71 and / or the wire cutting fingers 72. The wire cutting drive 73 drives the wire cutting base 71 and the wire cutting fingers 72 to move towards or away from each other to cut the copper wire located between the wire cutting base 71 and the wire cutting fingers 72. Thus, the wire cutting mechanism 7 achieves rapid cutting of the copper wire through the relative movement of the wire cutting base 71 and the wire cutting fingers 72, with a compact structure and controllable cutting force, avoiding burrs or wire pulling on the copper wire.

[0035] The aforementioned wire-cutting drive unit 73 can use existing linear drive mechanisms such as telescopic cylinders or telescopic poles, and its output end can be connected to the wire-cutting seat 71 or the wire-cutting finger 72 by means of screwing or welding. Alternatively, the aforementioned wire-cutting drive unit 73 can use existing clamping drive mechanisms such as clamping cylinders, or bidirectional linear drive mechanisms such as bidirectional screw nut linear modules, and its output end can be connected to the wire-cutting seat 71 and the wire-cutting finger 72 by means of screwing or welding.
