[0036] Reference throughout this specification to "one embodiment" or "an embodiment" means that a particular feature, structure, or characteristic described in connection with the embodiment is included in at least one embodiment of the application. Thus, the appearances of the phrase "in one embodiment" or "in some embodiments" in various places throughout this specification are not necessarily all referring to the same embodiment. Furthermore, the particular features, structures, or characteristics can be combined in any suitable manner in one or more embodiments. Figures 1 to 5 The stator auxiliary winding mold provided by the embodiment of the application is shown in the drawings, and will be described below. The stator auxiliary winding mold comprises:

[0037] A base 1, upper and lower winding support ears 2 and 3 are respectively hinged to the upper and lower ends of the base 1;

[0038] A stator top holding block 4, the stator top holding block 4 is connected with the base 1 through at least one connecting column 6;

[0039] The base 1 is provided with a sliding hole 11, one end of the connecting column 6 is fixed to the stator top holding block 4, and the other end penetrates into the sliding hole 11;

[0040] A resilient member, one end of the resilient member acts on the stator top holding block 4, and the other end acts on the base 1;

[0041] A wire hanging column 5, one end of the wire hanging column 5 is arranged on the base 1 or the stator top holding block 4, and the other end faces the stator to be wound.

[0042] In the embodiment, the upper winding support ear 2 and the lower winding support ear 3 provide a stable support structure for the winding process. When the stator winding operation is performed, the enameled wire needs to have appropriate support and guidance, and the upper winding support ear 2 and the lower winding support ear 3 cooperate to determine the starting position and path direction of the winding, thereby providing a support for the winding of the enameled wire. At the same time, the presence of the upper winding support ear 2 and the lower winding support ear 3 helps to maintain the tension during the winding process. If there is no appropriate support structure during winding, the enameled wire may be loose or excessively tight.

[0043] The stator top holding block 4 is mainly used for positioning and fixing the stator to be wound during the winding process. When the mold is working, after the stator to be wound is placed in a suitable position, the stator top holding block 4 can stably fix the stator to be wound through cooperation with the base 1 and other components. For example, when the stator to be wound is placed in the winding position, the stator top holding block 4 exerts pressure on the stator to be wound from the side, so that the position of the stator to be wound is accurately determined, and displacement of the stator to be wound during the winding process is prevented, just like using a clamp to clamp a workpiece to ensure that the position of the workpiece does not change during the machining process.

[0044] The connection column 6, the sliding hole 11 and the elastic member cooperate with each other to make the stator top holding block 4 always adhere to the outer surface of the to-be-wound stator. One end of the connection column 6 is fixed to the stator top holding block 4, and the other end penetrates into the sliding hole 11 of the base 1. This connection mode makes the stator top holding block 4 and the base 1 form an integral structure. When the wound turns are close to the center position of the to-be-wound stator, the elastic member is in the maximum deformation state. As the wound turns gradually move away from the center of the to-be-wound stator, the elastic member gradually releases the elastic potential energy, but always keeps the stator top holding block 4 on the outer surface of the to-be-wound stator.

[0045] During the winding process of the stator, the wire hanging column 5 provides a fixed position for the starting wire head, replaces the PIN needle on the surface of the stator core which is prone to breakage, solves the problem that the starting wire head has no place to be fixed due to the breakage or absence of the PIN needle, makes the winding work start smoothly, avoids the trouble of manually pulling the wire head, and thus improves the automation degree of the stator winding.

[0046] The stator auxiliary winding mold of the embodiment includes the base 1. The upper winding supporting lug 2 and the lower winding supporting lug 3 are respectively hinged to the upper end and the lower end of the base 1, can provide support and guidance for winding, determine the starting position and path direction of winding, maintain the winding tension and stability, assist the winding action and work cooperatively with other components. The stator top holding block 4 is connected to the base 1 through at least one connection column 6. The base 1 is provided with a sliding hole 11. One end of the connection column 6 is fixed to the stator top holding block 4, and the other end penetrates into the sliding hole 11, realizing the relative movement of the stator top holding block 4 and the base 1 and adapting to the force change in the winding process. One end of the elastic member acts on the stator top holding block 4, and the other end acts on the base 1, providing buffering and resetting functions and maintaining the balance of the winding tension. One end of the wire hanging column 5 is arranged on the base 1 or the stator top holding block 4, and the other end faces the to-be-wound stator, is used for fixing the starting wire head, replaces the PIN needle which is prone to breakage, guides the winding direction, guarantees the winding tension, makes the winding work start smoothly, and gets rid of the dependence on manual pulling of the wire head. The technical scheme of the embodiment improves the automation degree of the stator winding, avoids manual intervention caused by the PIN needle problem, reduces the labor cost and the risk of operation errors. The cooperative cooperation among the components of the winding mold makes the winding process more stable and efficient, can ensure the accuracy and neatness of the winding, improves the winding quality, and thus is beneficial to improving the overall efficiency and product quality of motor production, meets the demand of motor production and market for automatic and high-quality stator winding.

[0047] It should be noted that the wire hanging column 5 can be arranged on the base 1 or the stator top holding block 4, as long as it can hold the outer surface of the stator to be wound in the initial stage of winding the stator, and provide a fixed position for the starting wire head of the stator to be wound. In the embodiment, the elastic force applied by the elastic member is to push the stator top holding block 4 to the direction close to the stator to be wound, which can be a spiral compression spring or a sheet-shaped elastic strip.

[0048] In one embodiment, as shown in Figure 4 The wire hanging column 5 includes a first column body 51 and a second column body 53 sleeved on the first column body 51, and a return spring 52 is arranged between the first column body 51 and the second column body 53. The wire hanging column 5 adopts a double-layer column body structure, that is, composed of the first column body 51 and the second column body 53 sleeved outside the first column body 51, and the return spring 52 is arranged between the first column body 51 and the second column body 53. During the actual winding operation, when the enameled wire is wound around the wire hanging column 5, the double-layer column body structure can provide more flexible adaptability. For example, if the tension of the wire suddenly changes during winding, or the winding direction needs to be adjusted, due to the existence of the return spring 52, the second column body 53 can produce a certain displacement relative to the first column body 51. This displacement change can buffer the impact force caused by the sudden change of tension or the adjustment of winding direction, so that the winding process is more stable and smooth.

[0049] In addition, by arranging the wire hanging column 5 as an elastic wire hanging column 5, it can adapt to various winding requirements. The sizes of motor stators of different models and specifications may be different. The wire hanging column 5 structure with the return spring 52 can flexibly cope with various sizes of stators to be wound, and through the elastic adjustment of the spring, it is ensured that the wire hanging column 5 can hold the outer surface of the stator to be wound in the initial winding, and provide a fixed position for the starting wire head.

[0050] In one embodiment, as shown in Figure 2 and Figure 3 Two ear mounting plates 7 are arranged on both sides of the base 1 in the vertical direction, the upper winding ear 2 and the lower winding ear 3 are hinged between the two ear mounting plates 7, and a torsional spring is arranged at the hinge position. The stator top holding block 4 is provided with an ear abutting rod 44 at both ends of the wire, and the upper winding ear 2 and the lower winding ear 3 are provided with an abutting inclined surface 31 corresponding to the ear abutting rod 44.

[0051] Since the number of winding layers of some stator to be wound is more than one, the opening between the upper winding lug 2 and the lower winding lug 3 needs to be self-adaptively adjusted according to the number of winding layers. In the embodiment, the upper winding lug 2 and the lower winding lug 3 are both hinged to the lug mounting plate 7 and are provided with torsion springs at the hinged positions, which can provide the upper winding lug 2 and the lower winding lug 3 with a force to approach the upper and lower ends of the stator to be wound. The lug abutting rods 44 at the upper and lower ends of the stator holding block 4 can cooperate with the abutting inclined surfaces 31 on the upper winding lug 2 and the lower winding lug 3. When it is needed to increase the opening of the upper winding lug 2 and the lower winding lug 3, the base 1 can be displaced towards the stator holding block 4 to reduce the distance between the stator holding block 4 and the base 1. At this time, the lug abutting rods 44 can expand the opening between the upper winding lug 2 and the lower winding lug 3. When the base 1 is displaced away from the stator holding block 4, the distance between the stator holding block 4 and the base 1 is increased, and the force applied by the lug abutting rods 44 to the upper winding lug 2 and the lower winding lug 3 is gradually reduced. The upper winding lug 2 and the lower winding lug 3 can automatically reduce the opening under the action of the torsion springs. In this way, the opening between the upper winding lug 2 and the lower winding lug 3 can be self-adaptively adjusted according to the number of winding layers.

[0052] In one embodiment, as shown in Figure 2 and Figure 3 The base 1 is further provided with a connecting rod limiting plate 8, which is fixed to the side of the base 1 opposite to the stator holding block 4. A limiting hole is formed in the connecting rod limiting plate 8 and is opposite to the sliding hole 11. The connecting column 6 passes through the limiting hole, and the end of the connecting column 6 inserted into the sliding hole 11 is provided with a limiting block with a larger diameter than the limiting hole.

[0053] In the embodiment, the connecting rod limiting plate 8 is firmly installed on the side of the base 1 opposite to the stator holding block 4, and a limiting hole is carefully formed in the connecting rod limiting plate 8 and is opposite to the sliding hole 11 of the base 1. The connecting column 6 connecting the stator holding block 4 and the base 1 is fixed to the stator holding block 4 at one end and passes through the limiting hole of the connecting rod limiting plate 8 and then is inserted into the sliding hole 11 of the base 1. A limiting block with a larger diameter than the limiting hole is specially provided at the end of the connecting column 6 inserted into the sliding hole 11. In the mold assembly process, the connecting rod limiting plate 8 is first accurately positioned and fixed on the base 1 to ensure that the limiting hole is coaxial with the sliding hole 11, and then the connecting column 6 is inserted. The limiting block acts as a “stopper” to effectively prevent the connecting column 6 from coming out of the limiting hole.

[0054] In this embodiment, the connecting rod limiting plate 8 and the limiting hole provide a precise guide path for the connecting column 6, ensuring that the stator top holding block 4 and the base 1 always maintain the correct positional relationship during relative sliding, avoiding displacement deviation caused by external force impact or long-term use, making the winding mold structure more stable and reliable. The design of the limiting block cleverly solves the problem of accidental disconnection of the connecting column 6. During winding, especially under complex working conditions such as high-speed winding or mold vibration, if the connecting column 6 is disconnected, it will seriously affect the normal operation of the mold, and even damage the mold and the winding stator. The blocking action of the limiting block ensures the integrity of the mold and the continuity of the winding work. By limiting the activity range of the connecting column 6, unnecessary friction and collision between the connecting column 6 and the sliding hole 11 and the limiting hole are reduced, the part wear is reduced, the service life of the mold parts is prolonged, thereby reducing the mold maintenance frequency, reducing production cost, and improving production efficiency.

[0055] Further, as shown in Figure 2 and Figure 3 , in this embodiment, the number of connecting columns 6 is four, and the four connecting columns 6 are fixed to the four corners of the stator top holding block 4. The number of connecting rod limiting plates 8 is two, and the two connecting rod limiting plates 8 are arranged in pairs on the side of the base 1 opposite to the stator top holding block 4. The upper and lower ends of each connecting rod limiting plate 8 are provided with a limiting hole.

[0056] In one embodiment, as shown in Figure 2 and Figure 3 , the base 1 is also provided with a positioning column 9 opposite to the stator top holding block 4, the positioning column 9 is located between the two connecting rod limiting plates 8, the stator top holding block 4 is provided with a positioning hole 422 for the positioning column 9 to pass through, and the elastic member is a compression spring, the compression spring is arranged on the positioning column 9, and the compression spring is not shown in the figure.

[0057] In this embodiment, the positioning column 9 is precisely installed between the two connecting rod limiting plates 8 on the side of the base 1 facing the stator top holding block 4, and is perpendicular to the surface of the base 1. At the same time, a positioning hole 422 is processed on the corresponding position of the stator top holding block 4 for the positioning column 9 to pass through, and the sizes are precisely matched to ensure that the stator top holding block 4 can smoothly fit on the positioning column 9 during assembly or operation. In addition, a compression spring is selected as an elastic member and is arranged on the positioning column 9, one end abuts against the base 1, and the other end acts on the stator top holding block 4.

[0058] In this embodiment, the compression spring is arranged on the positioning column 9. On the one hand, the space of the positioning column 9 is fully utilized, so that the mold structure is more compact. On the other hand, the positioning column 9 provides a guiding function for the compression spring, so that the compression spring can only deform in the axial direction when it is compressed or stretched, thereby avoiding unstable states such as skewing and twisting, and thus stably and reliably playing the buffering and resetting functions, and effectively dealing with the force changes in the winding process. Precise positioning and stable elastic support enable the winding mold to maintain a good working state under complex winding conditions such as high-speed winding and frequent start-stop, thereby reducing the failure rate caused by problems such as part loosening and misalignment, improving the reliability and service life of the mold, reducing downtime for maintenance during production, and improving overall production efficiency.

[0059] In one embodiment, the wire hanging column 5 is arranged on the base 1, and the stator top holding block 4 is provided with a wire column hole 421 through which the wire hanging column 5 passes. During mold design and manufacturing, the wire hanging column 5 is firmly installed on the base 1, and is perpendicular to the surface of the base 1 and has a precise position, so as to meet the requirements of the winding starting point. At the same time, the wire column hole 421 through which the wire hanging column 5 passes is carefully drilled in the position corresponding to the wire hanging column 5 on the stator top holding block 4 by mechanical processing. The hole diameter of the wire column hole 421 is precisely matched with the diameter of the wire hanging column 5, so as to ensure that the wire hanging column 5 can smoothly pass through the stator top holding block 4, and the gap between them can meet the requirements of relative movement and will not cause the enameled wire to be clamped therein to cause winding failure during winding.

[0060] In one embodiment, the stator top holding block 4 includes a connecting rod mounting plate 41 and a stator top holding plate 42. The connecting rod mounting plate 41 is arranged on the side opposite to the connecting column 6, and the stator top holding plate 42 is arranged on the side opposite to the stator to be wound. The connecting rod mounting plate 41 is provided with a stepped hole 411, and the connecting column 6 is provided with a corresponding threaded hole at the end opposite to the connecting rod mounting plate 41. In the design and manufacturing process of the stator top holding block 4, it is innovatively divided into two functional components, the connecting rod mounting plate 41 and the stator top holding plate 42. The connecting rod mounting plate 41 is precisely positioned on the side opposite to the connecting column 6, and the stepped hole 411 is formed by a fine mechanical processing process. The key role of the stepped hole 411 is to accommodate the head of the bolt, and the large-diameter section of the stepped hole 411 specially reserves space for the head of the bolt. When the stator top holding block 4 is assembled, the bolt is completely hidden.

[0061] It should be noted that the connecting rod mounting plate 41 and the stator top holding plate 42 can be detachably connected by bolts.

[0062] In one embodiment, the stator top holding plate 42 is provided with a stator clamping plate 43 on each of the left and right sides. The stator clamping plate 43 assists in fixing the stator from the left and right sides, and in combination with the top holding effect of the stator top holding plate 42 from the front, a three-dimensional fixing mode is formed, which greatly limits the displacement freedom of the stator during the winding process, effectively prevents the stator from shaking, deviating, even falling off and other situations due to the influence of external forces such as winding tension, vibration and the like, ensures the accuracy of the winding position, and improves the winding quality.

[0063] It should be understood that the size of the serial number of each step in the above embodiment does not mean the order of execution, and the execution order of each process should be determined according to its function and internal logic, and should not constitute any limitation on the implementation process of the embodiments of the present application.

[0064] The above only describes optional embodiments of the present application and does not limit the present application. Any modification, equivalent replacement and improvement made within the spirit and principle of the present application shall be included in the protection scope of the present application.
