[0030] In addition, the technical features involved in different embodiments of the present invention described below can be combined with each other as long as they do not conflict with each other.

[0031] Please refer to Figures 1 to 8 , an embodiment of the present invention discloses a stator winding machine 100 .

[0032] In one embodiment, if Figure 1 As shown, the stator winding machine 100 includes a frame 1, a winding device 22 and a fixing fixture 3.

[0033] The frame 1 is provided with a workbench 10 , and the workbench 10 is used to carry the winding device 22 and the fixing fixture 3 so that the winding device 22 and the fixing fixture 3 cooperate with each other to automatically complete the winding 41 .

[0034] The winding device 22 includes a wire feeding structure 20, an X-axis motion mechanism 21 for left and right reciprocating motion, a Y-axis motion mechanism 22 for front and back reciprocating motion, a Z-axis motion mechanism 23 for up and down reciprocating motion and a clamping structure 24. The Y-axis motion mechanism 22 includes a first slide rail 221, a first slider 222 and a first connecting plate 223. The first slide rail 221 is fixed on the workbench 10 along the front and back direction, the first slider 222 is arranged on the first connecting plate 223, and the first slider 222 is slidably arranged on the first slide rail 221, so that the Y-axis motion mechanism 22 can move along the front and back direction.

[0035] The X-axis motion mechanism 21 comprises a second slide rail 211, a second slider 212 and a second connecting plate 213. The second slide rail 211 is fixed on the first connecting plate 223 along the left-right direction. The second slider 212 is arranged on the second connecting plate 213. The second slider 212 is slidably arranged on the second slide rail 211, so that the X-axis motion mechanism 21 can move along the left-right direction.

[0036] The Z-axis motion mechanism 23 includes a third slide rail 231, a third slider 232 and a third connecting plate 234. The third connecting plate 234 is disposed on the second connecting plate 213. The third slide rail 231 is disposed on the third connecting plate 234. The third slider 232 is slidably disposed on the third slide rail 231, so that the Z-axis motion mechanism 23 can move in the up and down direction. The wire feeding structure 20 is disposed on the third sliding block, so that the wire feeding structure 20 can realize up and down, left and right, and front and back reciprocating motion.

[0037] The fixed fixture 3 includes a fixed plate 31, a rotating mounting structure 32 and a clamping mechanism. The fixed plate 31 is used to support and carry the entire fixed fixture 3, so that the fixed fixture 3 can be subsequently installed on the stator winding machine 100 through the fixed plate 31. A first through hole is provided at the center of the fixed plate 31. The other end of the rotating mounting structure 32 passes through the first through hole of the fixed plate 31, and there is a gap between the rotating mounting structure 32 and the side wall of the first through hole, so that the rotating mounting structure 32 can be rotatably fixed on the fixed plate 31. The rotating mounting structure 32 is provided with a mounting groove 321, and the mounting groove 321 is used to place the stator core 40.

[0038] Among them, the clamping mechanism includes a clamping structure 33 and a driving structure 34. One end of the rotating mounting structure 32 is arranged on one end surface of the fixed plate 31. The clamping structure 33 is used to clamp the stator core 40 so that the stator core 40 is fixed. The clamping structure 33 can be swingably arranged on the rotating mounting structure 32, and the clamping mouth of the clamping structure 33 is arranged toward the mounting groove 321, so that the clamping mouth can clamp the stator core 40.

[0039] The driving structure 34 is used to drive the clamping mouth of the clamping structure 33 to open, so as to facilitate the stator core 40 to be placed in the installation groove 321, or to remove the stator core 40 after the wire 41 is wound. The driving structure 34 can be raised and lowered and arranged on the side of the fixed plate 31 facing the installation groove 321. The clamping structure 33 is located between the rotating installation structure 32 and the driving structure 34. When the driving structure 34 is in a descending state and is separated from the driving structure 34, the clamping structure 33 and the driving structure 34 are staggered in the working state, so that the clamping mouth can clamp the stator core 40; the driving structure 34 is provided with a driving surface 341 at a position corresponding to the clamping structure 33. When it is not in a working state, the driving structure 34 rises so that the clamping structure 33 is pressed against the driving surface 341, thereby opening the clamping mouth of the clamping structure 33, so as to facilitate the stator core 40 to be placed in the installation groove 321, or to remove the stator core 40 after the wire 41 is wound. The structure design of the fixed fixture 3 is compact, simple and low in cost; and the rotating installation structure 32 is provided with a wire hanging column 326, which is located on one side of the installation groove 321, and the fixed fixture 3 is located on the side of the wire feeding structure 20 provided with the wire nozzle 201, and the clamping and shearing structure 24 is arranged on the Z-axis motion mechanism 23 and is located on one side of the outlet 41 of the wire nozzle 201, so that the clamping and shearing structure 24 can hang the wire 41 coming out of the wire nozzle 201 on the terminal 41 column 326. When winding the wire 41, the wire 41 head located on the terminal 41 column 326 enters the stator core 40, and the rotating installation structure 32 is rotated at an angle to cooperate with the up and down movement of the winding device 22 to complete the winding 41. After the winding 41 is completed, the clamping and shearing structure 24 cuts the wire. Automatic wire hanging, automatic winding and automatic wire cutting are realized, and processing accuracy and production efficiency are improved.

[0040] In one embodiment, the wire feeding structure 20 includes a fixed frame 202, a first wire passing wheel 203, a second wire passing wheel 204, a first porcelain eye 205, a second porcelain eye 206 and a third wire passing wheel 207. The fixed frame 202 is arranged on the Z-axis motion mechanism 23, and the first wire passing wheel 203, the second wire passing wheel 204, the first porcelain eye 205, the second porcelain eye 206 and the third wire passing wheel 207 are then arranged on the fixed frame 202, so that the wire feeding structure 20 can realize reciprocating motion up and down, left and right, and front and back. The first wire-passing wheel 203 and the second wire-passing wheel 204 are respectively located on opposite sides of the Z-axis motion mechanism 23, the first porcelain eye 205, the second porcelain eye 206 and the third wire-passing wheel 207 are all located on the same center line 41, and the wire nozzle 201 is arranged on the fixed frame 202 and is located at the wire outlet 41 of the third wire-passing wheel 207, so that the wire 41 passes through the first wire-passing wheel 203, the second wire-passing wheel 204, the first porcelain eye 205, the second porcelain eye 206 and the third wire-passing wheel 207 in sequence and passes through the wire nozzle 201, thereby realizing automatic wire feeding 41, saving time and improving production efficiency.

[0041] Furthermore, the wire feeding structure 20 also includes a tension wheel 208, which is arranged on the workbench 10 and is located on one side of the first wire passing wheel 203. The wire 41 first passes through the tension wheel 208 and then passes through the first wire passing wheel 203. The tension wheel 208 can ensure that the transported wire 41 is in a tensioned state, avoiding the wire 41 from being in a loose state and affecting the winding effect of 41.

[0042] In one embodiment, the shearing structure 24 includes a first driving member, a shearing member and a wire clamping member. The first driving member is arranged on the Z-axis motion mechanism 23, the shearing member is arranged on the output end of the first driving member, and the wire clamping member is arranged on the first driving member and is located on one side of the shearing member, so that the shearing structure 24 can realize shearing and clamping at the same time, thereby reducing the structure.

[0043] In one embodiment, if Figure 4-Figure 8 As shown, the rotating mounting structure 32 includes a third driving member 322 and a mounting seat 323. One end of the third driving member 322 is arranged on the fixed plate 31. The output end of the third driving member 322 passes through the first through hole of the fixed plate 31 and is connected to the mounting seat 323. The end face of the mounting seat 323 is provided with a mounting groove 321. The third driving member 322 can be a rotating motor, so that the rotating mounting structure 32 can rotate, and then during the winding 41 process, the mounting seat 323 can drive the stator core 40 to rotate at an angle, and cooperate with the winding device 22 to complete the winding 41. The mounting seat 323 is a hollow cylindrical structure, which can specifically be a hollow regular cylinder or a hollow cylinder, preferably a hollow cylinder, with a simple structure and easy assembly.

[0044] Furthermore, the mounting seat 323 includes a mounting seat body 324 and a fixing ring 325. The fixing ring 325 is inserted into the mounting groove 321 on the mounting seat body 324. The inner ring diameter of the fixing ring 325 can be designed according to the stator core 40 of different specifications and sizes. That is, when it is necessary to fix the stator core 40 of different sizes, the fixing ring 325 with the corresponding inner ring diameter can be replaced to achieve preliminary fixation of the stator core 40, thereby avoiding the inner ring size of the fixing ring 325 being too large, and the stator core 40 being placed on the fixing ring 325 with too large a gap, causing the stator core 40 to be displaced during the winding 41 process.

[0045] In one embodiment, one end of the clamping structure 33 can be telescopically arranged on the end of the rotating mounting structure 32 away from the mounting groove 321, and the other end of the clamping structure 33 can be swingably arranged on the other end of the rotating mounting structure 32, and the clamping mouth of the clamping structure 33 is arranged toward the mounting groove 321, and the telescopic direction of the clamping structure 33 is opposite to the swinging direction of the clamping structure 33, so that when one end of the clamping structure 33 extends, the other end of the clamping structure 33 moves toward the mounting groove 321, so that the clamping mouth of the clamping structure 33 clamps the stator core 40, and when one end of the clamping structure 33 retracts, the other end of the clamping structure 33 moves away from the mounting groove 321, so that the clamping mouth of the clamping structure 33 opens, so that the stator core 40 is placed in the mounting groove 321, or the stator core 40 after the wire 41 is wound is removed.

[0046] Further, such as Figure 6 As shown, the clamping structure 33 includes at least two clamping components 331, and at least two clamping components 331 are evenly distributed on the outer wall of the mounting seat 323. The clamping components 331 can be 2, 3, 4, 5, 6, etc. In this embodiment, the number of the clamping components 331 is not specifically limited, and a suitable number can be selected according to actual conditions. For example, when the number of the clamping components 331 is 3, the three clamping components 331 are arranged on the outer wall of the mounting seat 323 and are evenly distributed on the outer circumference of the mounting seat 323, so that the clamping force on the stator core 40 is uniform, thereby avoiding the stator core 40 from tilting.

[0047] Furthermore, the clamping assembly 331 includes a clamping member 332, a connecting rod 333 and an elastic member 334. The clamping end of the clamping member 332 is arranged toward the mounting groove 321, so that multiple clamping members 332 can be combined to form a clamping opening to clamp the stator core 40. The other end of the clamping member 332 is connected to the swinging end of the connecting rod 333, so that when the connection swings, it can drive the clamping member 332 to swing, thereby realizing the opening of the clamping opening. One end of the elastic member 334 is fixed to the outer wall of the mounting seat 323, and the other end of the elastic member 334 is fixed to the telescopic end of the connecting rod 333, that is, the elastic member 334 is arranged between the mounting seat 323 and the connecting rod 333, and the mounting seat 323 is fixed on the fixing plate 31, and the connecting rod 333 is connected to the mounting seat 323 through the elastic member 334, so that the tension of the elastic member 334 can push the connecting rod 333 to extend away from the mounting seat 323, and because the swing end of the connecting rod 333 is fixed to the mounting seat 323 by a fulcrum design, the telescopic end of the connecting rod 333 drives the swing end of the connecting rod 333 to move toward the mounting groove 321 when extending away from the mounting seat 323, thereby causing the clamping end of the clamping member 332 to move toward the mounting groove 321, so that the clamping member 332 can clamp the stator core 40. The stator core 40 can be clamped only by the tension of the elastic member 334, and the clamping is achieved without the need for motor drive, thereby reducing the design of motor drive parts. This not only makes the structural design of the fixing fixture 3 compact and small, simple in structure, and easy to assemble, but also reduces the cost. Moreover, the greater the tension of the elastic member 334, the greater the distance that the telescopic end of the connecting rod 333 is driven away from the mounting seat 323, so that the swing end of the connecting rod 333 is closer to the mounting groove 321, thereby making the clamping opening smaller. The smaller the tension of the elastic member 334, the smaller the distance that the telescopic end of the connecting rod 333 is driven away from the mounting seat 323, so that the swing end of the connecting rod 333 is further away from the mounting groove 321, thereby making the clamping opening larger. Therefore, within the tension range of the elastic member 334, the fixing fixture 3 can clamp stator cores 40 of different specifications within a certain range, thereby improving the versatility of the fixing fixture 3.

[0048] Specifically, the clamping piece 332 is a strip plate structure, and the clamping end is set as an arc protrusion. The arc protrusion not only increases the contact area between the clamping piece 332 and the stator core 40 to improve the clamping force, but also avoids the area of ​​the clamping end being too large. When clamping, the clamping end cannot be completely in contact with the surface of the stator core 40, resulting in insufficient clamping force.

[0049] Furthermore, the clamping assembly 331 also includes a connecting assembly 335 and a pin 336. The connecting assembly 335 includes two connecting blocks, one end of each of the two connecting blocks is fixed on the mounting base 323, and the other ends of the two connecting blocks are provided with a second through hole, and the swinging end of the connecting rod 333 is located between the two connecting blocks, and a third through hole is provided at the position of the swinging end of the connecting rod 333 corresponding to the second through hole, and the pin 336 passes through a second through hole, a third through hole and another second through hole in sequence for active connection, so that the connecting rod 333 can swing, and the swinging direction of the swinging end of the connecting rod 333 is exactly opposite to the telescopic direction of the telescopic end of the connecting rod 333, so that the connecting rod 333 can drive the clamping member 332 to clamp the stator core 40 only by the tension of the elastic member 334.

[0050] Furthermore, a rotating member 337 is provided at the other end of the connecting rod 333, that is, a rotating member 337 is provided at one end of the connecting rod 333 close to the telescopic end. The rotating member 337 enables the clamping structure 33 to be inserted into the driving surface 341 of the driving structure 34 more smoothly. The rotating member 337 is a bearing with a simple structure and high movement accuracy.

[0051] In one embodiment, the driving structure 34 includes a second driving member 342 and a pressing ring 343. One end of the second driving member 342 is fixed on the surface of the fixing plate 31 facing the mounting groove 321. The output end of the second driving member 342 is arranged on the pressing ring 343. The driving surface 341 is arranged on the inner side wall of the pressing ring 343, so that the second driving member 342 can drive the pressing ring 343 to move upward or downward. When in a non-working state, the second driving member 342 drives the pressing ring 343 to move upward, so that the pressing ring 343 gradually approaches one end of the connecting rod 333 provided with a rotating member 337. As the height increases, the rotating member 337 moves downward. 337 contacts with the driving surface 341, and the driving surface 341 gives an inward squeezing force to the rotating member 337 at this time. The inward squeezing force pushes the elastic member 334 to retract, so that the swinging end of the connecting rod 333 moves away from the mounting groove 321, thereby driving the clamping member 332 to move away from the mounting groove 321, and then the clamping member 332 opens, which makes it easy to place the stator core 40 in the mounting groove 321, or to remove the stator core 40 after the wire 41 is wound. The clamping structure 33 can be driven to open through a driving member and a pressure ring 343. The structural design is compact and small, the structure is simple, the movement accuracy is high and the cost is low.

[0052] Specifically, the second driving member 342 may be a motor.

[0053] Further, such as Figure 7 and Figure 8As shown, the driving surface 341 is an inclined surface, which is arranged on the inner side wall of the position of the pressing ring 343 corresponding to the connecting rod 333, and the distance between the center line 41 of the pressing ring 343 and the inclined surface gradually decreases as the insertion depth of the clamping structure 33 becomes deeper, so that the clamping structure 33 can be smoothly inserted into the pressing ring 343 when the pressing ring 343 rises, and the telescopic end of the connecting rod 333 is gradually compressed as the pressing ring 343 rises, so that the elastic member 334 continues to retract, so that the swing end of the connecting rod 333 drives the clamping member 332 to gradually move away from the installation groove 321, thereby opening the clamping opening. The end of the inclined surface facing the fixed plate 31 is set as an arc protrusion, which plays a limiting role on the rotating member 337, preventing the rotating member 337 from directly carrying the connecting rod 333 through the pressing ring 343, resulting in the clamping structure 33 being unable to reset.

[0054] Furthermore, a guide rod 311 is provided on the fixing plate 31, one end of the guide rod 311 is provided on the fixing plate 31, and the pressure ring 343 can be movably sleeved on the guide rod 311, and the guide rod 311 improves the stability of the pressure ring 343 when performing an ascending or descending movement. The number of guide rods 311 can be 1, 2, 3, 4, 5, 6, etc., and a suitable number can be selected according to actual conditions. Preferably, the number of guide rods 311 is 2, which can improve the stability of the movement of the pressure ring 343 and avoid too many guide rods 311 resulting in a complex and bulky structure.
