[0002] The axial flux motor includes a stator and a rotor arranged in the axial direction. The stator includes a stator core, a coil winding and an insulating frame. The coil winding is wound on the insulating frame, and the insulating frame is sleeved on the stator core. During the assembly process of the stator, multiple insulating frames are arranged in a circular pattern, and then the wire is continuously wound on the insulating frame to complete the one-time preparation of the coil winding on the insulating frame, and finally the insulating frame with the coil winding is embedded in the stator core.

[0003] In the process of winding the wire on the insulating skeleton, it is necessary to make multiple insulating skeletons arranged in a circle diverge relative to the center of the circle, and use the gap between two adjacent insulating skeletons to provide winding space for the wire. When the insulating skeleton with the coil wound on it is embedded in the stator core, it is necessary to make multiple insulating skeletons arranged in a circle converge relative to the center of the circle to ensure that the insulating skeleton can be correctly embedded in the stator core. In addition, before the insulating skeleton is embedded in the stator core, it is necessary to organize the bridge wires of the coils on the insulating skeleton, and it is necessary to ensure that each insulating skeleton can move radially relative to the center of the circle independently, so that there is a gap between any two adjacent insulating skeletons, so as to remove the bridge wire stuck between any two adjacent insulating skeletons along the gap.

[0067] Embodiment 1

[0068] During the assembly process of the stator of the axial flux motor, multiple insulating skeletons are arranged in a circular pattern, and then the wire is continuously wound on the insulating skeleton to complete the one-time preparation of the coil winding on the insulating skeleton, and finally the insulating skeleton with the coil winding is embedded in the stator core. In the process of winding the wire on the insulating skeleton, it is necessary to make the multiple insulating skeletons arranged in a circular pattern diverge relative to the center of the circle, and use the gap between two adjacent insulating skeletons to provide winding space for the wire. When the insulating skeleton with the coil wound is embedded in the stator core, it is necessary to make the multiple insulating skeletons arranged in a circular pattern converge relative to the center of the circle to ensure that the insulating skeleton can be correctly embedded in the stator core. In addition, before the insulating skeleton is embedded in the stator core, it is necessary to organize the bridge wires of the coils on the insulating skeleton, and it is necessary to ensure that each insulating skeleton can move radially relative to the center of the circle independently, so that there is a gap between any two adjacent insulating skeletons, so as to remove the bridge wire stuck between any two adjacent insulating skeletons along the gap. The prior art has not yet developed relevant equipment to simultaneously meet the winding requirements, wire organization requirements and wire embedding requirements of the insulating skeleton.

[0069] For this reason, Figures 1 to 9As shown, this embodiment provides a wire embedding device for an insulating skeleton of an axial flux motor. The wire embedding device for the insulating skeleton of an axial flux motor comprises a first drive assembly 100, a second drive assembly 200, a third drive assembly 300 and an opening and closing fixture 400, wherein the opening and closing fixture 400 is used to support the insulating skeleton 2000, and multiple groups of elastic structures 410 are arranged in the opening and closing fixture 400, each group of elastic structures 410 is used to connect a single insulating skeleton 2000, and the first drive assembly 100 can drive the elastic structure 410 to stretch or contract synchronously along the radial direction of a preset point, so that the multiple insulating skeletons 2000 connected by the multiple groups of elastic structures 410 can switch between a divergent state, an initial state and a retracted state, the stator core 3000 and the insulating skeleton 2000 are facing each other along a preset direction, the second drive assembly 200 is used to connect and drive the stator core 3000 to move along a preset direction, and the third drive assembly 300 can drive the insulating skeleton 2000 in the retracted state to separate from the retracted fixture 400 along a preset direction.

[0070] The wire embedding device of the insulating skeleton of the axial flux motor supports a plurality of insulating skeletons 2000 arranged at intervals in a circle with a preset point as the center on the opening and closing fixture 400, so that each group of elastic structures 410 in the opening and closing fixture 400 is connected to an insulating skeleton 2000, and the first driving component 100 synchronously drives the plurality of elastic structures 410 to stretch or contract along the radial direction of the preset point on the plurality of insulating skeletons 2000, thereby achieving the effect of synchronously driving the plurality of insulating skeletons 2000 connected by the plurality of elastic structures 410 to gather or diverge along the radial direction of the preset point. Since the number of insulating skeletons 2000 remains unchanged, when the plurality of insulating skeletons 2000 are stretched or contracted along the preset point, the plurality of insulating skeletons 2000 are stretched or contracted along the radial direction of the preset point. When the points diverge radially, the distance between two adjacent insulating skeletons 2000 increases, meeting the winding requirements of the insulating skeleton 2000 and the wire; when multiple insulating skeletons 2000 are radially contracted along the preset point, the distance between two adjacent insulating skeletons 2000 is reduced to meet the wire embedding requirements of the insulating skeleton 2000 and the stator core 3000. Combined with the second driving member 210 driving the stator core 3000 to move in a preset direction and the third driving component 300 driving the insulating skeleton 2000 to disengage from the joint tooling 400 in a preset direction, the stator core 3000 and the insulating skeleton 2000 facing each other in the preset direction can be connected to the wire embedding. In addition, since each elastic structure 410 can converge or diverge radially along a preset point, after completing the winding of the wire and the insulating skeleton 2000, the insulating skeleton 2000 switches from the divergent state back to the initial state under the drive of the elastic structure 410. When it is necessary to take out the bridge wire between the two insulating skeletons 2000, the corresponding insulating skeleton 2000 can be directly bent to make the insulating skeleton 2000 diverge radially along the preset point to take out the bridge wire between the two insulating skeletons 2000, thereby meeting the wire management needs and improving the wire management efficiency.

[0071] It should be noted that, in this embodiment, the preset direction is the up and down direction. In other embodiments, the specific orientation of the preset direction can also be adjusted according to actual needs, and this embodiment does not make specific limitations.

[0072] Specifically, if Figures 4 to 9 As shown, the elastic structure 410 includes a fixed part 411, a movable part 412 and an elastic part 413, wherein the opening and closing tooling 400 also includes a supporting platform 420, the fixed part 411 is fixed on the supporting platform 420, the insulating frame 2000 is placed on the supporting end surface of the supporting platform 420, the movable part 412 is used to fix the insulating frame 2000, the movable part 412 and the fixed part 411 are arranged radially opposite to each other along the corresponding insulating frame 2000 and the preset point, and the movable part 412 and the fixed part 411 are located at one end of the insulating frame 2000 radially away from the preset point, the first driving component 100 can drive the movable part 412 to move radially along the preset point, the elastic part 413 is located between the fixed part 411 and the movable part 412, and the two ends of the elastic part 413 are respectively connected to the fixed part 411 and the movable part 412. By placing the insulating skeleton 2000 on the support platform 420 in the opening and closing tooling 400, and setting a fixed part 411 and a movable part 412 at one end of the insulating skeleton 2000 radially away from the preset point along the circle in which it is located, and ensuring that the fixed part 411 and the movable part 412 are arranged radially opposite to each other, the fixed part 411 and the support platform 420 are fixed, the movable part 412 and the insulating skeleton 2000 are clamped and fixed, and an elastic part 413 is set between the fixed part 411 and the movable part 412, and the first driving component 100 drives the movable part 412 to move radially, thereby driving the elastic part 413 to expand or contract radially. When the first driving component 100 drives all the elastic structures 410 to expand, the insulating skeleton 2000 is retracted relative to the preset point; when the first driving component 100 drives all the elastic structures 410 to compress, the insulating skeleton 2000 diverges relative to the preset point.

[0073] It should be noted that, in this embodiment, the elastic member 413 is a spring. The spring has a simple structure, is easy to disassemble and assemble, and has a long service life. In other embodiments, the elastic member 413 may also be a rubber block or other elastic structure, which is not specifically limited in this embodiment.

[0074] Combination Fig.10 and Fig.11The specific structure of the moving member 412 is described. The moving member 412 includes a tensioning portion 4121 and a docking portion 4122 connected to each other, the insulating frame 2000 has a through hole 2200 extending in the axial direction, the insulating frame 2000 is placed on the supporting platform 420 in a state of being axially perpendicular to the supporting end surface of the supporting platform 420, the tensioning portion 4121 extends into the through hole 2200 and supports and fixes the insulating frame 2000, the docking portion 4122 is connected to the elastic member 413, and the first driving assembly 100 can drive the docking portion 4122 to move radially along a preset point. By configuring the movable part 412 to be a tensioning part 4121 and a docking part 4122 connected in sequence, the tensioning part 4121 extends into the through hole 2200 of the insulating frame 2000 which is placed on the supporting platform 420 in a state where the supporting end face is axially perpendicular to the supporting platform 420. The insulating frame 2000 can be supported and fixed on the basis of supporting the insulating frame 2000, thereby ensuring the clamping stability of the insulating frame 2000. By connecting the docking part 4122 with the elastic part 413 and driving the docking part 4122 to move radially by the first driving component 100, the effect of stretching or compressing the elastic part 413 and driving the insulating frame 2000 to gather or diverge relative to a preset point is achieved.

[0075] In addition, in order to ensure the normal movement of the docking part 4122 in the moving part 412, a plurality of avoidance grooves 421 are arranged on the support platform 420 at circumferential intervals with a preset point as the center. A docking part 4122 is arranged in each avoidance groove 421, and each avoidance groove 421 extends radially along the preset point to provide avoidance space for the radial movement of the docking part 4122 along the preset point.

[0076] It should be noted that, in this embodiment, 18 groups of elastic structures 410 are arranged in a circle with a preset point as the center, and the opening and closing tool 400 provided in this embodiment can simultaneously clamp and fix up to 18 insulating frames 2000. In other embodiments, the number of elastic structures 410 in the opening and closing tool 400 can also be adjusted according to the specific number of insulating frames 2000 to be clamped, and this embodiment does not make a specific limitation.

[0077] As an alternative, Figure 2 and Figure 3As shown, the first drive assembly 100 includes a first drive member 110 and an adapter plate 120, wherein the adapter plate 120 is simultaneously connected to the docking parts 4122 of the moving parts 412 in all the elastic structures 410, and the first drive member 110 can drive the adapter plate 120 to rotate around a preset axis, so that the adapter plate 120 synchronously drives all the elastic structures 410 to stretch or contract radially along a preset point, and the preset axis coincides with the preset point and the preset axis is perpendicular to the circle surrounded by multiple insulating skeletons 2000. By connecting the adapter plate 120 to the docking parts 4122 in all the elastic structures 410 at the same time, and driving the adapter plate 120 to rotate around the preset axis by the first drive member 110, it is ensured that the preset axis coincides with the preset point and is perpendicular to the circle surrounded by the insulating skeleton 2000, thereby achieving the effect of synchronously driving the docking parts 4122 to stretch or compress radially along the preset point.

[0078] Specifically, if Figure 5 , Figure 7 as well as Fig. 9 As shown, a plurality of docking grooves 122 are arranged at circumferential intervals around a preset axis on the adapter plate 120, and a docking portion 4122 of the elastic structure 410 is arranged in each docking groove 122. The docking groove 122 rotates with the adapter plate 120 and drives the docking portion 4122 of the elastic structure 410 to stretch or contract radially along a preset point. By arranging a plurality of docking grooves 122 at circumferential intervals along a preset axis on the adapter plate 120, each docking portion 4122 is arranged in a docking groove 122, and when the adapter plate 120 rotates around the preset axis, the groove wall of the docking groove 122 drives the corresponding docking portion 4122 to stretch or compress radially along a preset point. It should be noted that in this embodiment, each docking groove 122 extends circumferentially relative to the preset axis and is inclined radially, so that when the docking groove 122 rotates around the preset axis, the docking groove 122 can drive the docking portion 4122 to stretch or compress radially relative to the preset point.

[0079] Combination Figure 3 , Figure 5 , Figure 7 as well as Fig. 9The specific driving principle of the first driving assembly 100 is described. The first driving assembly 100 also includes a mounting seat 130, wherein the adapter plate 120 is rotatably connected to the mounting seat 130 around a preset axis, a first adapter portion 131 is provided on the mounting seat 130, the first driving member 110 is rotatably connected to the first adapter portion 131, a second adapter portion 121 is provided on the adapter plate 120, the second adapter portion 121 is rotatably connected to the output end of the first driving member 110, and the output end of the first driving member 110 is configured to drive the second adapter portion 121 to move along a straight line. It should be noted that in this embodiment, the first driving member 110 is a linear cylinder, and a crank slider mechanism is formed between the first driving member 110, the adapter plate 120 and the mounting seat 130. When it is necessary to drive the insulating frame 2000 to diverge or converge relative to a preset point, the output end of the first driving member 110 drives the second adapter portion 121 to move along a straight line. Since the first driving member 110 and the adapter plate 120 are respectively rotatably connected to the mounting seat 130, the first driving member 110 and the adapter plate 120 are respectively rotated relative to the mounting seat 130 to convert the linear drive of the first driving member 110 on the second adapter portion 121 into the rotation of the adapter plate 120 around the preset axis and the rotation of the first driving member 110 relative to the mounting seat 130. The transmission principle of the crank slider mechanism belongs to the prior art and will not be described in detail here.

[0080] In one alternative, if Figure 1 and Figure 2 As shown, the second drive assembly 200 includes a second drive member 210 and a connector 220, wherein the connector 220 is connected to the output end of the second drive member 210, the connector 220 is clamped and fixed with a stator core 3000, and the second drive member 210 can drive the connector 220 to move along a preset direction. By clamping and fixing the stator core 3000 on the connector 220, the second drive member 210 drives the connector 220 to move along a preset direction, which can drive the stator core 3000 to move along the preset direction, so as to achieve the effect of embedding the stator core 3000 and the insulating frame 2000 together along the preset direction. It should be noted that, in this embodiment, the second drive member 210 is a linear cylinder. The linear cylinder has a simple structure, is sensitive to reaction, and is easy to disassemble and assemble. In other embodiments, the second drive member 210 can also be a linear motor, a rotary motor and a lead screw nut structure or other linear drive structure, which is not specifically limited in this embodiment.

[0081] In order to improve the driving effect on the stator core 3000, the second driving assembly 200 further includes a guide column 230, wherein the guide column 230 extends along a preset direction, and a guide hole is provided on the connecting member 220, and the guide hole is slidably matched with the guide column 230. When the second driving member 210 drives the connecting member 220 to move along the preset direction, the connecting member 220 can slide along the guide column 230 under the guidance of the guide hole, so as to ensure the movement accuracy of the connecting member 220 along the preset direction.

[0082] In addition, in this embodiment, four guide posts 230 are provided in the second driving assembly 200, and the four guide posts 230 are arranged at intervals along the circumference of the connecting member 220. The connecting member 220 is provided with four guide holes at intervals along the circumference, and each guide hole is slidably matched with a guide post 230 to further improve the driving effect on the stator core 3000. In other embodiments, the specific number of guide posts 230 can also be adjusted according to actual needs, and this embodiment does not make a specific limitation.

[0083] As an alternative, Fig.11 As shown, the third driving assembly 300 includes a third driving member and an abutment member, wherein the abutment member is connected to the output end of the third driving member, and the insulating frame 2000 is respectively provided with limit baffles 2100 at both ends along its axial direction, and the limit baffles 2100 extend radially outward along the insulating frame 2000, and the axial direction of the insulating frame 2000 is parallel to the preset direction. The abutment member is located at one end of the insulating frame 2000 away from the stator core 3000 along its axial direction. When the insulating frame 2000 is retracted relative to the preset point, the abutment member and the limit baffle 2100 are arranged opposite to each other along the preset direction, and the third driving member can drive the abutment member to move along the preset direction. By clamping the insulating frame 2000 on the tensioning part 4121 in the opening and closing tooling 400 in a state where the axial direction is parallel to the preset direction, the abutment is set at one end of the insulating frame 2000 away from the stator core 3000 in the preset direction, and the abutment is directly opposite to the limit baffle 2100 in the insulating frame 2000 in the preset direction. When the third driving member drives the abutment to move in the preset direction, the abutment can abut against the limit baffle 2100 and drive the insulating frame 2000 to disengage from the tensioning part 4121 in the preset direction. Combined with the second driving member 210 driving the stator core 3000 in the preset direction, the stator core 3000 and the insulating frame 2000 are embedded and fixed. It should be noted that, in this embodiment, the third driving member is a linear cylinder, and a through hole extending along a preset direction is provided on the supporting platform 420 in the opening and closing tooling 400. The abutment member is located in the through hole and slides with the through hole. When the third driving member drives the abutment member to move along the preset direction, the through hole can provide guidance for the movement of the abutment member.
