The stator fixing mechanism includes a stator bearing seat and a stator reinforcement assembly. The stator bearing seat is arranged on the base. The stator bearing seat is configured to bear the stator. The stator reinforcement assembly includes a reinforcement bracket and a reinforcement head. The reinforcement bracket is connected to the stator bearing seat or the base. The reinforcement head is connected to the reinforcement bracket. The reinforcement head is configured to move relative to the reinforcement bracket to approach or move away from the stator bearing seat. The rotor fixing structure includes a rotor fixing seat and a rotor displacement assembly. The rotor fixing seat is configured to assemble the rotor. The rotor fixing seat is arranged on the rotor displacement assembly. The rotor fixing seat and the stator bearing seat are distributed along a first direction. The rotor displacement assembly is arranged on the base. The rotor displacement assembly is configured to drive the rotor fixing seat to move relative to the base along the first direction. The guide mechanism includes a guide column and a guide displacement assembly. The guide column is configured to be able to pass through the stator and to be able to dock with the rotor along the first direction. The guide column is arranged on the guide displacement assembly. The guide column and the stator bearing seat are distributed along the first direction. The guide displacement assembly is arranged on the base. The guide displacement assembly is configured to drive the guide column to move relative to the base along the first direction, and the guide column can move on the side of the stator bearing seat away from the rotor fixing seat.

[0005] In the above embodiment, the reinforcement head moves toward the stator bearing seat, thereby pressing the stator placed on the stator bearing seat to fix the stator relative to the stator bearing seat, so that the guide column and the rotor pass through the stator. The reinforcement head moves away from the stator bearing seat, so that the stator placed on the stator bearing seat can be taken away, and the stator can be placed conveniently. When the rotor fixing seat is moved by the rotor displacement assembly, it can carry the rotor together, so that the rotor moves in the correct direction, so as to achieve accurate assembly of the rotor and the stator. At the same time, the guide column can move with the cooperation of the guide displacement assembly, so as to pass through the stator and dock with the rotor, and then the rotor moves together with the guide column. Under the guidance of the guide column, the accuracy of the rotor movement direction is improved, which is conducive to reducing the collision between the rotor and the stator during the assembly process, so as to improve the motor assembly accuracy and the qualified yield of the motor, and it is also conducive to preventing the user from being pinched by the stator and the rotor during assembly, so as to improve the safety during assembly.

[0006] In some embodiments of the present application, the stator bearing seat is provided with a first inclined portion and a second inclined portion. The distribution direction of the first inclined portion and the second inclined portion is perpendicular to the first direction and perpendicular to the moving direction of the reinforcement head. The first inclined portion is provided with a first inclined surface. The first inclined surface is inclined toward the second inclined portion and is inclined relative to the moving direction of the reinforcement head. The second inclined portion is provided with a second inclined surface. The second inclined surface is inclined toward the first inclined portion and is inclined relative to the moving direction of the reinforcement head.

[0007] In the above embodiment, the first inclined portion and the second inclined portion can apply supporting force to the stator in different directions, thereby constraining the position of the stator while supporting the stator, and improving the stability of the stator bearing seat when carrying the stator. At the same time, the first inclined portion and the second inclined portion can cooperate with the reinforcement head to apply force to the stator in three directions perpendicular to the first direction, which is beneficial to prevent the stator from shaking when the guide column and the rotor pass through the stator. And when stators of different sizes are placed on the stator bearing seat, the stator can abut against different positions of the first inclined surface and different positions of the second inclined surface, which is beneficial to improve the adaptability range of the stator bearing seat to stators of different sizes.

[0008] In some embodiments of the present application, the stator bearing seat is provided with a limiting portion, which is provided on the same side of the first inclined portion and the second inclined portion away from the rotor fixing seat along the first direction.

[0009] In the above embodiment, when the rotor fixing seat moves toward the stator bearing seat to pass the rotor through the stator, the limit portion can stop the stator, which helps to prevent the stator from moving due to the force applied by the rotor fixing seat, thereby fixing the stator and the rotor relatively, so as to facilitate the assembly operation of fixedly connecting the stator and the rotor and improve the assembly accuracy.

[0010] In some embodiments of the present application, the reinforcement bracket includes a first adapter and a second adapter. The first adapter is connected to the stator bearing seat or the base. The second adapter is rotatably connected to the first adapter. The second adapter is configured to be lockable with one of the stator bearing seat or the base. The reinforcement head is movably disposed on the second adapter.

[0011] In the above embodiment, by setting the reinforcement head on the second adapter, the reinforcement head can be quickly transferred by rotation to make room for the stator. When the reinforcement head is needed to fix and hold the stator, the position of the reinforcement head can be fixed by locking the rotation of the second adapter. The rotational coordination of the first adapter and the second adapter is conducive to simplifying the action of assembling the motor and improving the efficiency of assembling the motor.

[0012] In some embodiments of the present application, the base or the stator bearing seat is provided with a first socket. The second adapter is provided with a second socket. The reinforcement bracket also includes a latch. The latch is configured to be inserted into the first socket and the second socket at the same time to lock the rotation of the second adapter. The insertion direction of the latch intersects with the rotation axis of the second adapter.

[0013] In the above embodiment, when the plug is inserted into the first and second sockets at the same time, the movement of the second socket relative to the first socket is stopped by the plug, thereby locking the second adapter so that the second adapter cannot rotate. By plugging and pulling out the plug, the rotation of the second adapter can be locked and unlocked, which is convenient and labor-saving, and is conducive to improving the assembly efficiency of the motor.

[0014] In some embodiments of the present application, the reinforcement head includes a pressing portion and a moving portion, wherein the pressing portion is connected to the moving portion, and the moving portion is threadedly connected to the reinforcement bracket.

[0015] In the above embodiment, the moving part can move linearly along the direction of its rotation axis while rotating relative to the reinforcement bracket, thereby driving the pressing part to move linearly, so that the pressing part is close to or away from the stator bearing seat, thereby pressing the stator against the stator bearing seat or allowing the stator to be removed from the stator bearing seat. At the same time, due to the threaded fit between the moving part and the reinforcement bracket, after the pressing part moves into place and is not interfered by external forces, the pressing part can apply a stable force to the stator to improve the fixing effect on the stator, which is beneficial to improving the assembly accuracy of the motor.

[0016] In some embodiments of the present application, the rotor displacement assembly includes a rotor sliding seat and a rotor slide rail. The rotor slide rail is arranged on the base and extends along the first direction. The rotor sliding seat is slidably arranged on the rotor slide rail. The rotor fixed seat is arranged on the rotor sliding seat. The guide displacement assembly includes a guide sliding seat and a guide slide rail. The guide slide rail is arranged on the base and extends along the first direction. The guide sliding seat is slidably arranged on the guide slide rail. The guide column is arranged on the guide sliding seat.

[0017] In the above embodiment, the rotor fixing seat slides along the rotor slide rail through the rotor sliding seat to improve the accuracy and stability of the rotor movement, and the guide column slides along the guide slide rail through the guide sliding seat to improve the accuracy and stability of the guide column movement, thereby improving the assembly accuracy of the stator and the rotor.

[0018] In some embodiments of the present application, the rotor displacement assembly further comprises a drive motor, which is disposed on the base and configured to drive the rotor sliding seat to slide.

[0019] In the above embodiment, the rotor fixing seat moves with the rotor driven by the driving motor, and can provide resistance to the magnetic force generated during the assembly process of the stator and the rotor, so as to facilitate the rotor to move toward the stator at a stable and controllable speed. On the one hand, it is beneficial to avoid the rotor colliding with the stator and improve the assembly accuracy and the yield rate of qualified products. On the other hand, it is beneficial to prevent users from being pinched and improve the safety of assembly.

[0020] In some embodiments of the present application, the rotor fixing mechanism further includes a rotor bracket. The rotor bracket is fixedly arranged on the rotor sliding seat. The rotor fixing seat is detachably connected to the rotor bracket. The guide mechanism further includes a guide bracket and a guide fixing seat. The guide bracket is fixedly arranged on the guide sliding seat. The guide fixing seat is arranged on the guide bracket. The guide column is detachably connected to the guide bracket via the guide fixing seat.

[0021] In the above embodiment, the rotor fixing seat can be removed from the rotor bracket to facilitate replacement of the rotor fixing seat, thereby improving the adaptability range of rotors of different sizes. The rotor fixing seat and the rotor bracket are detachably connected to reduce the impact on the rotor displacement assembly when replacing the rotor fixing seat, which is conducive to maintaining the accurate and stable moving direction when driving the rotor to move. By setting the guide fixing seat, it is convenient for the guide sliding seat to stably support the guide column through the guide bracket to improve the stability of the assembly of the rotor and the stator; and it is convenient to replace different guide columns to improve the adaptability range of the guide column to stators and rotors of different sizes.

[0022] In some embodiments of the present application, the guide column is provided with a docking hole. The docking hole is located on a side of the guide column facing the rotor fixing seat. The docking hole is configured for inserting the rotating shaft of the rotor.

[0023] In the above embodiment, the rotor and the guide column can be docked by inserting the rotating shaft of the rotor into the docking hole, so as to guide the rotor to move accurately relative to the stator. In addition, by setting the docking hole to cooperate with the rotor, when the guide column and the rotor are relatively close, the two can be docked and matched, the operation logic is simple, and it is conducive to improving the assembly efficiency of the motor.

Obviously, the described embodiments are only part of the embodiments of the present application, rather than all of the embodiments.

[0080] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as those commonly understood by those skilled in the art.

[0081] The terms "first", "second", "third", etc. are used for descriptive purposes only and are not to be construed as indicating or implying relative importance.

[0082] An embodiment of the present application provides a motor assembly device. The motor assembly device includes a base, a stator fixing mechanism, a rotor fixing mechanism and a guide mechanism. The stator fixing mechanism includes a stator bearing seat and a stator reinforcement assembly. The stator bearing seat is arranged on the base. The stator bearing seat is configured to bear the stator. The stator reinforcement assembly includes a reinforcement bracket and a reinforcement head. The reinforcement bracket is connected to the stator bearing seat or the base. The reinforcement head is connected to the reinforcement bracket. The reinforcement head is configured to move relative to the reinforcement bracket to approach or move away from the stator bearing seat. The rotor fixing structure includes a rotor fixing seat and a rotor displacement assembly. The rotor fixing seat is configured to assemble the rotor. The rotor fixing seat is arranged on the rotor displacement assembly. The rotor fixing seat and the stator bearing seat are distributed along a first direction. The rotor displacement assembly is arranged on the base. The rotor displacement assembly is configured to drive the rotor fixing seat to move relative to the base along a first direction. The guide mechanism includes a guide column and a guide displacement assembly. The guide column is configured to be able to pass through the stator and to be able to dock with the rotor along the first direction. The guide column is arranged on the guide displacement assembly. The guide column and the stator bearing seat are distributed along the first direction. The guide displacement assembly is arranged on the base. The guide displacement assembly is configured to drive the guide column to move relative to the base along the first direction, and the guide column can move on the side of the stator bearing seat away from the rotor fixing seat.

[0083] The reinforcement head moves toward the stator bearing seat, thereby pressing the stator placed on the stator bearing seat to fix the stator relative to the stator bearing seat, so that the guide column and the rotor can pass through the stator. The reinforcement head moves away from the stator bearing seat, so that the stator placed on the stator bearing seat can be removed and the stator can be placed conveniently. When the rotor fixing seat is moved by the rotor displacement assembly, it can carry the rotor together, so that the rotor moves in the correct direction, so as to achieve accurate assembly of the rotor and the stator. At the same time, the guide column can move with the cooperation of the guide displacement assembly, so as to pass through the stator and dock with the rotor, and then the rotor moves together with the guide column. Under the guidance of the guide column, the accuracy of the rotor movement direction is improved, which is conducive to reducing the collision between the rotor and the stator during the assembly process, so as to improve the motor assembly accuracy and the qualified yield of the motor, and it is also conducive to preventing the user from being pinched by the stator and the rotor during assembly, so as to improve the safety during assembly.

[0084] Some embodiments of the present application are described in detail below in conjunction with the accompanying drawings. In the absence of conflict, the following embodiments and features in the embodiments can be combined with each other.

[0085] See also Figure 1 and Figure 2 An embodiment of the present application provides a motor assembly device 100 . The motor assembly device 100 is used to assemble a motor 200 .

[0086] See also Figure 1 and Figure 2 In some embodiments, the motor 200 to be assembled is an inner rotor motor. The motor 200 includes a stator 201 and a rotor 202, and the rotor 202 is located inside the stator 201. Specifically, when assembling the motor 200, the rotor 202 needs to be inserted into the stator 201.

[0087] See also Figure 1 and Figure 2 In some embodiments, the motor assembly device 100 includes a base 1, a stator fixing mechanism 2, a rotor fixing mechanism 3 and a guide mechanism 4. The stator fixing mechanism 2, the rotor fixing mechanism 3 and the guide mechanism 4 are all arranged on the base 1, and the three are distributed along the first direction X. Among them, the stator fixing mechanism 2 is used to fix the stator 201 to be assembled, and the rotor fixing mechanism 3 is used to fix the rotor 202 to be assembled, and the stator fixing mechanism 2 and the rotor fixing mechanism 3 can cooperate with each other to make the stator 201 and the rotor 202 move relative to each other along the first direction X to realize the assembly action, and the guide mechanism 4 can guide the relative movement of the stator 201 and the rotor 202 along the first direction X.

[0088] See also Figure 1 and Figure 2In some embodiments, the stator fixing mechanism 2 includes a stator bearing seat 21 and a stator reinforcement assembly 22. The stator bearing seat 21 is provided on the base 1. The stator bearing seat 21 is configured to bear the stator 201. The stator reinforcement assembly 22 includes a reinforcement bracket 221 and a reinforcement head 222. The reinforcement bracket 221 is connected to the stator bearing seat 21 or the base 1. The reinforcement head 222 is connected to the reinforcement bracket 221. The reinforcement head 222 is configured to move relative to the reinforcement bracket 221 to approach or move away from the stator bearing seat 21. It can be understood that in some embodiments, the movement direction of the reinforcement head 222 relative to the reinforcement bracket 221 intersects with the first direction X. The reinforcement head 222 moves toward the stator bearing seat 21, thereby pressing the stator 201 placed on the stator bearing seat 21 to fix the stator 201 relative to the stator bearing seat 21, so as to facilitate the guide column 41 (described later) and the rotor 202 to pass through the stator 201. The reinforcing head 222 moves away from the stator bearing seat 21 , so that the stator 201 placed on the stator bearing seat 21 can be taken away and the stator 201 can be placed conveniently.

[0089] The rotor 202 fixing structure includes a rotor fixing seat 31 and a rotor displacement assembly 32. The rotor fixing seat 31 is configured to assemble the rotor 202. The rotor fixing seat 31 is arranged on the rotor displacement assembly 32. The rotor fixing seat 31 and the stator bearing seat 21 are distributed along the first direction X. The rotor displacement assembly 32 is arranged on the base 1. The rotor displacement assembly 32 is configured to drive the rotor fixing seat 31 to move relative to the base 1 along the first direction X. When the rotor fixing seat 31 moves through the rotor displacement assembly 32, it can carry the rotor 202 to move together, so that the rotor 202 moves in an accurate direction, so as to realize the accurate assembly of the rotor 202 and the stator 201.

[0090] The guide mechanism 4 includes a guide column 41 and a guide displacement assembly 42. The guide column 41 is configured to pass through the stator 201 and to dock with the rotor 202 along the first direction X. The guide column 41 is disposed on the guide displacement assembly 42. The guide column 41 and the stator bearing seat 21 are distributed along the first direction X. The guide displacement assembly 42 is disposed on the base 1. The guide displacement assembly 42 is configured to drive the guide column 41 to move relative to the base 1 along the first direction X, and the guide column 41 can move on the side of the stator bearing seat 21 away from the rotor fixing seat 31. The guide column 41 can move with the cooperation of the guide displacement assembly 42, so as to pass through the stator 201 and dock with the rotor 202, and then the rotor 202 moves together with the guide column 41. Under the guidance of the guide column 41, the accuracy of the moving direction of the rotor 202 is improved, which is beneficial to reduce the collision between the rotor 202 and the stator 201 during the assembly process, so as to improve the assembly accuracy of the motor 200 and the qualified yield of the motor 200, and is beneficial to prevent the user from being pinched by the stator 201 and the rotor 202 during assembly, so as to improve the safety during assembly.

[0091] It is understandable that in some embodiments, the relative position relationship among the stator bearing seat 21 , the rotor fixing seat 31 and the guide post 41 is configured to satisfy that the stator 201 , the rotor 202 and the guide post 41 are coaxial along the first direction X.

[0092] It is understandable that in some embodiments, the rotor fixing seat 31 is provided with connection holes corresponding to part of the holes of the rotor 202 so as to allow fasteners to fix the rotor 202 .

[0093] See also Figure 1 and Figure 2 In some embodiments, the stator support 21, the rotor fixing seat 31 and the guide column 41 are replaced at the same time, and the central axes of the stator 201 placed on the stator support 21, the rotor 202 fixed to the rotor fixing seat 31 and the guide column 41 are maintained on the same axis to facilitate adaptation to the size of the motor 200 to be assembled of different specifications.

[0094] See also Figures 1 to 3 In some embodiments, the stator bearing seat 21 is provided with a first inclined portion 211 and a second inclined portion 212. The distribution direction of the first inclined portion 211 and the second inclined portion 212 is perpendicular to the first direction X and perpendicular to the moving direction of the reinforcement head 222. The first inclined portion 211 is provided with a first inclined surface 2111. The first inclined surface 2111 is inclined toward the second inclined portion 212 and is inclined relative to the moving direction of the reinforcement head 222. The second inclined portion 212 is provided with a second inclined surface 2121. The second inclined surface 2121 is inclined toward the first inclined portion 211 and is inclined relative to the moving direction of the reinforcement head 222.

[0095] The first inclined portion 211 and the second inclined portion 212 can apply supporting forces to the stator 201 in different directions, thereby constraining the position of the stator 201 while supporting the stator 201, and improving the stability of the stator bearing seat 21 when carrying the stator 201. At the same time, the first inclined portion 211 and the second inclined portion 212 can cooperate with the reinforcement head 222 to apply forces to the stator 201 in three directions perpendicular to the first direction X, which is beneficial to prevent the stator 201 from shaking when the guide column 41 and the rotor 202 pass through the stator 201. And when stators 201 of different sizes are placed on the stator bearing seat 21, the stator 201 can abut against different positions of the first inclined surface 2111 and abut against different positions of the second inclined surface 2121, which is beneficial to improve the adaptation range of the stator bearing seat 21 to stators 201 of different sizes.

[0096] See also Figures 1 to 3In some embodiments, the first inclined surface 2111 is inclined at an angle of no more than 45° relative to the moving direction of the reinforcement head 222, which is conducive to making the force component of the first inclined surface 2111 on the stator 201 toward the second inclined surface 2121 not less than the force component toward the reinforcement head 222. The second inclined surface 2121 is inclined at an angle of no more than 45° relative to the moving direction of the reinforcement head 222, which is conducive to making the force component of the second inclined surface 2121 on the stator 201 toward the first inclined surface 2111 not less than the force component toward the reinforcement head 222. Usually, when the motor assembly device 100 is in use, the first inclined portion 211 and the second inclined portion 212 are spaced apart in the horizontal direction, and the above-mentioned structural arrangement is conducive to enhancing the stabilizing effect of preventing the stator 201 from shaking in the horizontal direction.

[0097] See also Figures 1 to 3 In some embodiments, the first inclined portion 211 and the second inclined portion 212 are spaced apart. The stator bearing seat 21 is provided with a partition surface 213. The partition surface 213 is opposite to the reinforcement head 222 in the moving direction of the reinforcement head 222. The first inclined surface 2111 and the second inclined surface 2121 are connected by the partition surface 213. Then, the angle between the first inclined surface 2111 and the partition surface 213 is an obtuse angle, and the angle between the second inclined surface 2121 and the partition surface 213 is an obtuse angle.

[0098] By providing the separation surface 213, the first inclined surface 2111 and the second inclined surface 2121 are prevented from being directly connected, which helps to avoid forming a narrow corner space between the two surfaces that is inconvenient for accommodating the stator 201, thereby reducing space waste and improving space utilization.

[0099] See also Figures 1 to 3 In some embodiments, the stator bearing seat 21 is provided with a limiting portion 214. The limiting portion 214 is provided on the same side of the first inclined portion 211 and the second inclined portion 212 along the first direction X away from the rotor fixing seat 31.

[0100] When the rotor fixing seat 31 moves toward the stator bearing seat 21 to pass the rotor 202 through the stator 201, the limiting portion 214 can stop the stator 201, which helps to prevent the stator 201 from moving due to the force applied by the rotor fixing seat 31, thereby fixing the stator 201 and the rotor 202 relatively, so as to facilitate the assembly operation of fixing the stator 201 and the rotor 202 and improve the assembly accuracy.

[0101] See also Figures 1 to 3In some embodiments, the reinforcement bracket 221 includes a first adapter 2211 and a second adapter 2212. The first adapter 2211 is connected to the stator bearing seat 21 or the base 1. The second adapter 2212 is rotatably connected to the first adapter 2211. The second adapter 2212 is configured to be locked with one of the stator bearing seat 21 or the base 1. The reinforcement head 222 is movably disposed on the second adapter 2212.

[0102] By setting the reinforcing head 222 on the second adapter 2212, the reinforcing head 222 can be quickly transferred by rotation to make room for taking and placing the stator 201. When the reinforcing head 222 is needed to fix and hold the stator 201, the second adapter 2212 is locked in rotation to fix the position of the reinforcing head 222. The rotational cooperation between the first adapter 2211 and the second adapter 2212 is conducive to simplifying the action of assembling the motor 200 and improving the efficiency of assembling the motor 200.

[0103] See also Figures 1 to 3 In some embodiments, the first adapter 2211 is a plate-like structure. The second adapter 2212 includes a first adapter plate 2212a, a second adapter plate 2212b and a third adapter plate 2212c. The first adapter plate 2212a, the second adapter plate 2212b and the third adapter plate 2212c are sequentially connected in a direction perpendicular to the first direction X. The first adapter plate 2212a is rotatably connected to the first adapter 2211. The third adapter plate 2212c is connected to the base 1 or the stator bearing seat 21, and can be relatively locked or unlocked. The reinforcement head 222 is connected to the second adapter plate 2212b.

[0104] See also Figures 1 to 3 In some embodiments, the base 1 or the stator bearing seat 21 is provided with a first plug hole 11. The second adapter 2212 is provided with a second plug hole 2212d. The reinforcement bracket 221 further includes a latch (not shown). The latch is configured to be inserted into the first plug hole 11 and the second plug hole 2212d at the same time to lock the rotation of the second adapter 2212. The insertion direction of the latch intersects with the rotation axis of the second adapter 2212.

[0105] When the latch is inserted into the first socket 11 and the second socket 2212d at the same time, the movement of the second socket 2212d relative to the first socket 11 is stopped by the latch, thereby locking the second adapter 2212 so that the second adapter 2212 cannot rotate. By plugging and pulling out the latch, the second adapter 2212 can be locked and unlocked, which is convenient and labor-saving, and is conducive to improving the assembly efficiency of the motor 200.

[0106] In other embodiments, the reinforcement bracket 221 may further include an active buckle, and the second adapter 2212 is locked with the base 1 or the stator bearing seat 21 through the active buckle. Alternatively, the reinforcement bracket 221 may further include a clamp, and the second adapter 2212 is locked with the base 1 or the stator bearing seat 21 through the clamp. Alternatively, the reinforcement bracket 221 may further include a claw with a slot, the second adapter 2212 is provided with a convex edge, the base 1 or the stator bearing seat 21 is provided with a convex edge, and the slot of the claw clamps the two convex edges to achieve locking.

[0107] See also Figures 1 to 3 In some embodiments, the reinforcement bracket 221 is connected to the base 1 to facilitate the replacement of the stator bearing seat 21, thereby improving the adaptability of the stator 201 of different sizes. It can be understood that in some embodiments, the first adapter 2211 and the second adapter 2212 are both connected to the base 1, and the first jack 11 is provided on the base 1.

[0108] See also Figures 1 to 3 In some embodiments, the reinforcement head 222 includes a pressing portion 2221 and a moving portion 2222. The pressing portion 2221 is connected to the moving portion 2222. The moving portion 2222 is threadedly connected to the reinforcement bracket 221.

[0109] While the moving part 2222 rotates relative to the reinforcement bracket 221, it can move linearly along the direction of its rotation axis, thereby driving the pressing part 2221 to move linearly, so that the pressing part 2221 is close to or away from the stator bearing seat 21, thereby pressing the stator 201 against the stator bearing seat 21 or allowing the stator 201 to be removed from the stator bearing seat 21. At the same time, due to the threaded cooperation between the moving part 2222 and the reinforcement bracket 221, after the pressing part 2221 moves into place and is not interfered by external forces, the pressing part 2221 can apply a stable force to the stator 201 to improve the fixing effect on the stator 201, which is beneficial to improving the assembly accuracy of the motor 200.

[0110] In other embodiments, the movable portion 2222 can be slidably matched with the reinforcement bracket 221, and the reinforcement head 222 can also include an elastic portion, which is arranged between the pressing portion 2221 and the reinforcement bracket 221 or between the movable portion 2222 and the reinforcement bracket 221. The elastic force of the elastic portion can directly or indirectly act on the pressing portion 2221 so that the pressing portion 2221 presses the stator 201.

[0111] See also Figure 1 , Figure 2 and Figure 4In some embodiments, the rotor displacement assembly 32 includes a rotor sliding seat 321 and a rotor slide rail 322 .

The rotor fixing seat 31 is disposed on the rotor sliding seat 321 .

[0112] The rotor fixing seat 31 slides along the rotor slide rail 322 through the rotor sliding seat 321 to improve the accuracy and stability of the movement of the rotor 202, thereby improving the assembly accuracy of the stator 201 and the rotor 202.

[0113] See also Figure 1 , Figure 2 and Figure 4 In some embodiments, the rotor displacement assembly 32 further includes a driving motor 323. The driving motor 323 is disposed on the base 1. The driving motor 323 is configured to drive the rotor sliding seat 321 to slide.

[0114] The rotor fixing seat 31 moves with the rotor 202 driven by the driving motor 323, and can provide resistance to the magnetic force generated during the assembly process of the stator 201 and the rotor 202, so that the rotor 202 moves toward the stator 201 at a stable and controllable speed. On the one hand, it is helpful to avoid the rotor 202 colliding with the stator 201, improving the assembly accuracy and the yield rate of qualified products, and on the other hand, it is helpful to prevent users from being pinched and improve the safety of assembly.

[0115] See also Figure 1 , Figure 2 and Figure 4 It is understood that in some embodiments, the rotor displacement assembly 32 further includes a screw 324.

[0118] The rotor fixing seat 31 can be removed from the rotor bracket 33 to facilitate replacement of the rotor fixing seat 31, thereby improving the adaptability of the rotor 202 to different sizes. The rotor fixing seat 31 and the rotor bracket 33 are detachably connected, which reduces the impact on the rotor displacement assembly 32 when replacing the rotor fixing seat 31, and is conducive to maintaining the accurate and stable movement direction when driving the rotor 202 to move.

[0121] By inserting the rotating shaft 2021 of the rotor 202 into the docking hole 411, the rotor 202 can be docked with the guide column 41, so as to guide the rotor 202 to accurately move relative to the stator 201. In addition, by providing the docking hole 411 to cooperate with the rotor 202, when the guide column 41 and the rotor 202 are relatively close, the two can be docked and matched, and the operation logic is simple, which is conducive to improving the assembly efficiency of the motor 200.

[0122] See also Figure 1 , Figure 2 and Figure 5 In some embodiments, the guide displacement assembly 42 includes a guide sliding seat 421 and a guide rail 422 . The guide rail 422 is disposed on the base 1 and extends along the first direction X. The guide sliding seat 421 is slidably disposed on the guide rail 422 . The guide column 41 is disposed on the guide sliding seat 421 .

[0123] The guide column 41 slides along the guide rail 422 through the guide sliding seat 421 to improve the accuracy and stability of the movement of the guide column 41, thereby improving the assembly accuracy of the stator 201 and the rotor 202.

[0125] By setting the guide fixing seat 44, the guide sliding seat 421 can stably support the guide column 41 through the guide bracket 43 to improve the stability of the assembly of the rotor 202 and the stator 201; and it is convenient to replace different guide columns 41 to improve the adaptability range of the guide column 41 to different specifications and sizes of the stator 201 and the rotor 202.

[0126] See also Figure 1 , Figure 2 and Figure 5 In some embodiments, the guide post 41 is detachably connected to the guide fixing seat 44, so that the guide post 41 can be directly replaced. It can be understood that in some embodiments, a groove is provided on the side of the guide fixing seat 44 facing the stator bearing seat 21, which can accommodate part of the structure of the guide post 41, so as to facilitate the rapid positioning of the relative position between the guide post 41 and the guide fixing seat 44, and facilitate the replacement of the guide post 41. In other embodiments, the guide fixing seat 44 is detachably connected to the guide bracket 43, and the guide post 41 can be replaced together with the guide fixing seat 44.

Flip the second adapter 2212, close it, and lock it. Rotate the reinforcement head 222 so that the reinforcement head 222 presses the stator 201. Move the guide sliding seat 421 so that the guide column 41 passes through the stator 201. The drive motor 323 drives the rotor sliding seat 321 to slide, so that the rotor 202 moves toward the guide column 41, and the rotating shaft 2021 of the rotor 202 is inserted into the docking hole 411 of the guide column 41.

The rotor 202 is fixedly connected to the stator 201 to achieve the assembly of the rotor 202 and the stator 201.
