[0062] Embodiment one

[0063] In the assembling process of the stator, the wire is continuously wound on the insulation framework to complete the one-time preparation of the coil winding on the insulation framework, and finally the insulation framework with the coil winding is embedded in the stator core. In the process of winding the wire on the insulation framework, the wire output by the feeding roller needs to be pre-tightened to ensure the winding effect of the wire. However, in the actual winding process, the tight wire will be pulled back to the feeding roller, and cannot be directly wound on the insulation framework.

[0064] In order to solve the above problems, such as Figures 1-4As shown, the embodiment provides a winding device for an axial flux motor insulation framework. The winding device for the axial flux motor insulation framework comprises a framework clamping mechanism 100, a wire clamping mechanism 200, and a winding mechanism 300. The framework clamping mechanism 100 is used to clamp and fix the insulation framework 2000. The winding mechanism 300 can drive the wire 3000 to be wound on the insulation framework 2000. The wire clamping mechanism 200 comprises a pressing assembly 210 and a wire clamping and cutting assembly 220. The pressing assembly 210 can press and fix the wire 3000. The wire clamping and cutting assembly 220 can clamp and fix the wire 3000 and cut the clamped and fixed wire 3000. The winding mechanism 300 drives the wire 3000 to be switched between the first state of being pressed and fixed by the pressing assembly 210 and the second state of being clamped and fixed by the wire clamping and cutting assembly 220.

[0065] The winding device for the axial flux motor insulation framework clamps and fixes the insulation framework 2000 through the framework clamping mechanism 100. The wire 3000 is always in a fixed state to prepare the coil winding, and the winding effect of the coil winding is guaranteed.

[0066] It should be noted that in the embodiment, the wire 3000 as the winding material is wound on the feeding roller. The winding mechanism 300 leads the wire 3000 out of the feeding roller and winds the wire 3000 on the insulation framework 2000 on the basis of switching the wire 3000 between the first state of being pressed and fixed by the pressing assembly 210 and the second state of being clamped and fixed by the wire clamping and cutting assembly 220.

[0067] As an optional solution, as Figures 1-4As shown, the pressing assembly 210 comprises a first mounting base 214, a first pressing piece 211 and a first driving piece 212. The first mounting base 214 is fixed at the framework clamping mechanism 100. The first pressing piece 211 extends in the up-down direction. The first mounting base 214 is provided with a through hole 2141 extending in the vertical direction. The first pressing piece 211 is movably arranged in the through hole 2141. The first driving piece 212 is connected with the first pressing piece 211. The wire 3000 is located between the first pressing piece 211 and the first mounting base 214. The first driving piece 212 can drive the first pressing piece 211 to move along the through hole 2141, so as to clamp and fix the wire 3000 between the first pressing piece 211 and the first mounting base 214. By arranging the first mounting base 214 at the framework clamping mechanism 100, opening the through hole 2141 extending in the up-down direction in the first mounting base 214, containing the first pressing piece 211 in the through hole 2141, and using the first driving piece 212 to drive the first pressing piece 211 to move along the through hole 2141, the wire 3000 can be clamped and fixed between the first mounting base 214 and the first pressing piece 211.

[0068] Specifically, as shown in the figure, Figure 5 The side wall of the first pressing piece 211 is provided with a pressing groove 2111 for accommodating the wire 3000. The first driving piece 212 drives the pressing groove 2111 to extend out of the upper end surface of the first mounting base 214 or retract into the upper end surface of the first mounting base 214. By arranging the pressing groove 2111 for accommodating the wire 3000 on the side wall of the first pressing piece 211, when it is needed to press and fix the wire 3000, the first driving piece 212 drives the first pressing piece 211 to move upward, so that the pressing groove 2111 on the first pressing piece 211 extends out of the upper end surface of the first mounting base 214. Then the wire 3000 is placed in the pressing groove 2111. Subsequently, the first driving piece 212 drives the first pressing piece 211 to move downward, so that the pressing groove 2111 retracts into the upper end surface of the first mounting base 214, thereby clamping and fixing the wire 3000 between the first pressing piece 211 and the first mounting base 214.

[0069] In addition, the pressing assembly 210 further comprises at least two limiting members 213, wherein the at least two limiting members 213 are arranged on the first mounting base 214 along the preset shape together with the first pressing member 211, the limiting members 213 are fixed to the first mounting base 214, and each limiting member 213 extends in the vertical direction, and the wire winding mechanism 300 drives the wire 3000 to be wound outside the preset shape surrounded by the at least two limiting members 213 and the first pressing member 211. By additionally arranging the at least two limiting members 213 on the first mounting base 214, the at least two limiting members 213 are arranged on the first mounting base 214 together with the first pressing member 211 along the preset direction, the wire winding mechanism 300 drives the wire 3000 to be wound outside the preset shape surrounded by the first pressing member 211 and the limiting members 213, and the tail wire of the coil winding can be arranged in the preset shape, so that the tail wire of the coil winding is conveniently arranged, and the efficiency of arranging the tail wire of the coil winding is improved.

[0070] In combination Figure 6 The specific structure of the clamping and cutting assembly 220 will be described. The clamping and cutting assembly 220 comprises a second mounting base 226, a second driving member 224, a cutter 223, and a first clamping member 221 and a second clamping member 222 oppositely arranged along a first direction, wherein the second driving member 224 is arranged on the second mounting base 226, the second driving member 224 is connected with the first clamping member 221 and the second clamping member 222, a clamping space is formed between the first clamping member 221 and the second clamping member 222, the clamping space is used to accommodate the wire 3000, the second driving member 224 can drive the first clamping member 221 and the second clamping member 222 to move towards each other or move away from each other, the cutter 223 is fixed to the outer wall of the first clamping member 221 or the second clamping member 222 extending along the first direction, and the cutter 223 extends along the first direction and the cutter head of the cutter 223 extends into the clamping space.

[0071] By arranging the wire 3000 in the clamping space formed by the oppositely arranged first clamping member 221 and second clamping member 222, connecting the oppositely arranged first clamping member 221 and second clamping member 222 with the second driving member 224, and driving the first clamping member 221 and the second clamping member 222 to move towards each other and move away from each other by the second driving member 224, the wire 3000 in the clamping space can be clamped and fixed. By arranging the cutter 223 on the side wall of the first clamping member 221 or the second clamping member 222 extending along the first direction, the cutter head of the cutter 223 extends into the clamping space. After the first clamping member 221 and the second clamping member 222 move towards each other and clamp and fix the wire 3000, if the second driving member 224 continues to drive the first clamping member 221 and the second clamping member 222 to move towards each other, the cutter head of the cutter 223 will cut the wire 3000 to cut the clamped and fixed wire 3000.

[0072] It should be noted that in the embodiment, the first direction is the left-right direction, the second driving member 224 is a linear cylinder, and the cutting knife 223 is arranged on the side wall of the second clamping member 222 extending in the left-right direction. In other embodiments, the specific direction of the first direction can also be adjusted according to actual needs, the second driving member 224 can also be a linear motor or other linear driving structure, and the cutting knife 223 can also be arranged on the first clamping member 221, and the embodiment is not limited specifically.

By arranging the third driving member 225 on the second mounting seat 226, connecting the second driving member 224 with the third driving member 225, and driving the second driving member 224 to move arbitrarily in space by the third driving member 225, the positions of the second driving member 224 and the oppositely arranged first clamping member 221 and second clamping member 222 can be adjusted according to actual needs, and the wire rod 3000 in different positions can be clamped and fixed.

[0074] It should be noted that in the embodiment, the wire rod 3000 will only be offset in the up-down direction relative to the first clamping member 221 and the second clamping member 222, so the third driving member 225 in the embodiment only drives the second driving member 224 to move in the up-down direction. In other embodiments, the third driving member 225 should be a three-axis driving structure, the third driving member 225 drives the first clamping member 221 and the second clamping member 222 to move arbitrarily in the left-right direction, the front-rear direction and the up-down direction, so as to realize arbitrary driving of the first clamping member 221 and the second clamping member 222 in space.

[0075] In an optional solution, as Figure 2 , Figure 7 and Figure 8As shown, the skeleton clamping mechanism 100 comprises a carrier 120 and a clamping assembly 110, wherein the upper end surface of the carrier 120 is used to support the axial insulation skeleton 2000 in the up-down direction, the clamping assembly 110 comprises a positioning member 111 and a tensioning member 112, the positioning member 111 is fixed on the upper end surface of the carrier 120, the insulation skeleton 2000 has a through hole extending in the axial direction, and the positioning member 111 is located in the through hole. The tensioning member 112 can extend into the through hole and jointly tension the insulation skeleton 2000 in the horizontal direction with the positioning member 111. By placing the insulation skeleton 2000 in the state of extending in the axial direction in the up-down direction on the carrier 120, and locating the positioning member 111 in the through hole extending in the axial direction in the insulation skeleton 2000, and extending the tensioning member 112 into the through hole, the insulation skeleton 2000 is jointly tensioned and fixed by the tensioning member 112 and the positioning member 111, thereby realizing stable clamping of the insulation skeleton 2000.

[0076] In order to further improve the clamping effect of the tensioning member 112 and the positioning member 111 on the insulation skeleton 2000, the skeleton clamping mechanism 100 further comprises a locking assembly 130, wherein the locking assembly 130 comprises a fourth driving member 131 and an abutting member 132, the fourth driving member 131 is fixed on the carrier 120, part of the tensioning member 112 extends out of the through hole, the outer side wall of the part of the tensioning member 112 extending out of the through hole is provided with a positioning groove 1121, the abutting member 132 is opposite to the positioning groove 1121 in a preset direction, the abutting member 132 is connected with the fourth driving member 131, and the fourth driving member 131 can drive the abutting member 132 to move in the preset direction. By driving the abutting member 132 to move in the preset direction and abut and position with the positioning groove 1121 in the tensioning member 112 through the fourth driving member 131, the movement of the tensioning member 112 in the up-down direction can be prevented, so as to ensure the tensioning effect of the tensioning member 112 and the positioning member 111 on the insulation skeleton 2000.

When the fourth driving member 131 drives the abutting member 132 to move in the preset direction and approach the positioning groove 1121, the elastic member 134 is compressed in the preset direction. When the fourth driving member 131 stops working, the elastic member 134 in the compressed state drives the stop member 133 and the abutting member 132 to move away from the positioning groove 1121 under the action of the elastic force of the elastic member 134, so as to realize the effect that the abutting member 132 is automatically separated from the positioning groove 1121. It should be noted that, in the embodiment, the fourth driving member 131 is a linear cylinder, and the elastic member 134 is a spring.
