[0045] Embodiments of the present invention are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and should not be construed as limiting the present invention.

[0046] The following is for reference. Figures 2-4A motor stator and rotor assembly apparatus for an electric motor according to an embodiment of the present invention is described, comprising: a stand 11, a frame 12, a first support plate 13, and a second support plate 14. The stand 11 is provided with a base plate 111 suitable for supporting a motor housing. The frame 12 is disposed on the stand 11 and is provided with a slide rail 121 extending in the height direction. The first support plate 13 is located on one side of the base plate 111 in the height direction and is slidably connected to the slide rail 121. A first limiting portion 131 is detachably provided on the first support plate 13 and is selectively abutting one end of the motor rotor. The second support plate 14 is located on the other side of the base plate 111 in the height direction and is slidably connected to the slide rail 121. A second limiting portion 141 is detachably provided on the second support plate 14, at least a portion of which passes through the base plate 111 and is selectively abutting the other end of the motor rotor.

[0047] Currently, the manufacturing process of electric motors requires the rotor to be assembled into the stator. However, the assembly of the stator and rotor of an electric motor is usually done manually using simple tooling. Manual assembly cannot guarantee the positioning accuracy of the stator and rotor during assembly, which affects the fit of the bearings and the stop. Therefore, a stator and rotor assembly mechanism is usually used to assemble the stator and rotor of the motor. However, the existing stator and rotor assembly mechanism can only assemble the stator and rotor of the same model of motor. When assembling other models of motors, an additional stator and rotor assembly mechanism needs to be designed, which increases the cost.

[0048] like Figure 2 As shown, specifically, the motor stator and rotor assembly equipment 10 includes a stand 11 and a frame 12. The stand 11 provides support for the entire equipment. Support feet can be provided at the bottom of the stand 11 to ensure the overall stability of the motor stator and rotor assembly equipment 10 and to prevent the motor stator and rotor assembly equipment 10 from sliding relative to the ground, thereby improving the reliability of the motor stator and rotor assembly equipment 10. A base plate 111 can be provided on the stand 11. The base plate 111 and the stand 11 can be detachably connected by bolts or screws, or the base plate 111 and the stand 11 can be detachably connected by snap-fit ​​or plug-in. The base plate 111 can be used to support the motor housing. At the same time, the base plate 111 can also limit the movement of the motor housing, ensuring that the motor can remain stationary relative to the base plate 111 during stator and rotor assembly, so as to facilitate the assembly of the motor rotor and motor stator.

[0049] The frame 12 can be mounted on the stand 11. The frame 12 can be used to install other parts in the equipment. The frame 12 and the stand 11 can be fixed with bolts. The frame 12 is provided with a column extending in the height direction. The column can be provided with a slide rail 121. The first support plate 13 and the second support plate 14 can be connected to the slide rail 121 and slide relative to the slide rail 121. Further, the first support plate 13 can be located on one side of the base plate 111 in the height direction, and the second support plate 14 can be located on the other side of the base plate 111 in the height direction. The first support plate 13 is detachably provided with a first limiting part 131. The first limiting part 131 can be selectively abutted against one end of the motor rotor. It is understood that the first support plate 13 and the first limiting part 131 are detachably connected. For example, the first support plate 13 and the first limiting part 131 can be detachably connected by bolts or screws. The first limiting part 131 can be selectively abutted against one end of the motor rotor.

[0050] It should be noted that the first support plate 13 can slide along the slide rail 121 toward the motor housing to abut against one end of the first limiting part 131 and the motor rotor. The second support plate 14 is detachably provided with a second limiting part 141. For example, the second support plate 14 and the second limiting part 141 can be detachably connected by bolts or screws. At least a portion of the second limiting part 141 can pass through the base plate 111, and the end of the second limiting part 141 can selectively abut against the other end of the motor rotor. Similarly, the second support plate 14 can slide along the slide rail 121 toward the motor housing to abut against the other end of the motor rotor. Since the first support plate 13 is detachably connected to the first limiting part 131 and the second support plate 14 is detachably connected to the second limiting part 141, when assembling the stator and rotor of different models of motors, it is only necessary to replace the first limiting part 131 and the second limiting part 141 of the corresponding model to meet the requirements of stator and rotor assembly of the motor. In a specific embodiment, both the first support plate 13 and the second support plate 14 are provided with sliders 132 on the side facing the slide rail 121, and the sliders 132 can be slidably connected to the slide rail 121.

[0051] In the actual assembly process, the motor housing is first placed on the base plate 111. The first limiting part 131 and the second limiting part 141 are moved to abut against the two ends of the motor rotor. Then, the first limiting part 131 and the second limiting part 141 are moved again to move the motor rotor into the motor housing and assemble it with the stator. Then, the first limiting part 131 and the second limiting part 141 are separated from the two ends of the motor rotor. Finally, the motor housing is removed from the base plate 111 to complete the assembly of the motor stator and rotor.

[0052] In short, the first tray 13 of the motor stator and rotor assembly equipment 10 of this application embodiment is detachably connected to the first limiting part 131, and the second tray 14 is detachably connected to the second limiting part 141. Therefore, when assembling stators and rotors of different models of motors, it is only necessary to replace the first limiting part 131 and the second limiting part 141 of the corresponding model to meet the requirements of motor stator and rotor assembly. Moreover, by replacing the first limiting part 131 and the second limiting part 141, the motor stator and rotor assembly equipment 10 can also be applied to single motor and dual motor structures, which improves the compatibility of the motor stator and rotor assembly equipment 10 and reduces the cost of the equipment.

[0053] like Figure 2 and Figure 3 As shown, in some embodiments of this application, the first limiting part 131 may include a first changing plate 1311, a first locking member 1312, and a first push rod 1313. The first changing plate 1311 may have a first mounting hole extending through it in the height direction. The first locking member 1312 may be disposed on the first changing plate 1311 and may correspond to the first mounting hole. The first push rod 1313 may be disposed through the first locking member 1312 and the first mounting hole. One end of the first top plate facing the base plate 111 may abut against one end of the motor rotor. The first push rod 1313 may be detachably connected to the first locking member 1312, thereby enabling the replacement of the first push rod 1313. For example, when applied to different models of single motors, the first push rod 1313 can be replaced to meet the size requirements of the motor rotor. When applied to different models of dual motors, the entire first changing plate 1311 can be replaced to meet the requirements.

[0054] In some embodiments of this application, the outer peripheral wall of the first push rod 1313 may be formed with a first threaded portion, and the inner peripheral wall of the first locking member 1312 may be formed with a second threaded portion. The second threaded portion can be threadedly engaged with the first threaded portion to connect the first push rod 1313 and the first locking member 1312. The end of the first push rod 1313 away from the substrate 111 may also be formed with a rocker arm portion 1314. The rocker arm portion 1314 can rotate axially, thereby driving the first push rod 1313 as a whole to move in the height direction.

[0055] Understandably, after the motor housing is placed on the base plate 111, the motor rotor is initially positioned by moving the first support plate 13 and the second support plate 14. After the second limiting part 141 abuts against one end of the motor rotor, the operator can manually control the rocker arm 1314 to rotate the first push rod 1313 relative to the first locking member 1312, thereby driving the first push rod 1313 to move in the height direction until the first push rod 1313 abuts against the other end of the motor rotor, thus clamping the motor rotor. Then, the first support plate 13 and the second support plate 14 are moved to move the motor rotor into the motor housing and assemble it with the motor stator.

[0056] like Figure 2 and Figure 3 As shown, in some embodiments of this application, the first limiting part 131 further includes a guide post 1315. The guide post 1315 can be disposed on the side of the first changing plate 1311 facing the base plate 111, and the guide post 1315 can extend in the height direction. The guide post 1315 can be connected to the first changing plate 1311 or the first locking member 1312. The first push rod 1313 is disposed through the guide post 1315, and the first top plate and the guide post 1315 can be clearance-fitted. The guide post 1315 can play a guiding role, ensuring that when the operator operates the rocker arm 1314, the first push rod 1313 can move in the height direction along the guide post 1315, preventing the first push rod 1313 from deviating and ensuring the stability of the first push rod 1313 when it moves.

[0057] like Figure 1 As shown, in some embodiments of this application, the second limiting part 141 may include a second changing plate 1411, a second locking member 1412 and a second push rod 1413. The second changing plate 1411 may be detachably connected to the second tray 14. In a specific embodiment, the second changing plate 1411 and the second tray may be connected by bolts. A second mounting hole extending through the second profile plate 1411 can be formed on the second profile plate 1411. A second locking member 1412 can be disposed on the second profile plate 1411 and can be disposed corresponding to the second mounting hole. A second push rod 1413 can be disposed through the second locking member 1412 and the second mounting hole. One end of the second push rod 1413 facing the base plate 111 can abut against the other end of the motor rotor. The second push rod 1413 can be detachably connected to the second locking member 1412. When applied to different models of single motors, the first push rod 1313 and the second push rod 1413 can be replaced to meet the size of the motor rotor. When applied to different models of dual motors, the first profile plate 1311 and the second profile plate 1411 can be replaced to meet the requirements.

[0058] like Figure 2As shown in some embodiments of this application, the motor stator and rotor assembly equipment 10 may further include a drive device 15. The drive device 15 may be mounted on the frame 12 and has a drive end 151 extending in the height direction. The drive end 151 may pass through the first shape-changing plate 1311 and the second shape-changing plate 1411 and be power-connected to the first shape-changing plate 1311 and the second shape-changing plate 1411. In a specific embodiment, the drive device 15 may be a motor and the drive end 151 may be a connecting screw. The connecting screw may be threadedly connected to the first shape-changing plate 1311 and the second shape-changing plate 1411. The motor may drive the connecting screw to rotate, thereby causing the first shape-changing plate 1311 and the second shape-changing plate 1411 to slide on the slide rail 121. The motor may be power-connected to the reduction mechanism to ensure that the rotational speed of the drive end 151 meets the requirements.

[0059] Furthermore, a bearing seat can also be provided on the frame 12. The bearing seat can be fitted onto the outer end of the drive end 151 to ensure that the drive end 151 is more stable when rotating. The bearing seat can be connected to the frame 12 through a fixing plate. For example, the bearing seat and the fixing plate can be connected by bolts. The fixing plate can extend in the width direction, and both ends of the fixing plate in the width direction can be connected to the frame 12 by bolts. Multiple bearing seats can be constructed. Using multiple bearing seats can further improve the stability of the drive end 151.

[0060] like Figure 4 As shown, in some embodiments of this application, the motor stator and rotor assembly device 10 may further include a tray 112. The tray 112 may be disposed on a base plate 111 and may move relative to the base plate 111. A support surface may be formed on the tray 112, which may be used to support the motor housing. A support block 1121 and a second fastener 18 may be disposed on the support surface. The support block 1121 may be in contact with the bottom of the motor housing. In a specific embodiment, multiple support blocks 1121 may be constructed, and multiple support blocks 1121 may be spaced apart on the support surface. The support block 1121 may prevent wear between the motor housing and the tray 112. The support block 1121 may be constructed as a rubber part, which reduces the vibration of the motor housing and increases the friction between the motor housing and the support block, making the motor housing more stable during stator and rotor assembly. The second fastener 18 may serve to fix the motor housing. Furthermore, the second push rod 1413 may be selectively inserted through the tray 112, thereby ensuring that the second push rod 1413 can penetrate the motor housing and abut against the motor rotor.

[0061] like Figure 4As shown, in some embodiments of this application, a roller conveyor assembly 16 may be provided between the substrate 111 and the tray 112. The roller conveyor assembly 16 can drive the tray 112 to move on the substrate 111. For example, when the motor needs to be assembled with the stator and rotor, the roller conveyor assembly 16 can drive the tray 112 to move to the outer end. When the motor housing is placed on the tray 112, the tray 112 is then driven to move directly above the substrate 111 to facilitate the assembly of the stator and rotor. Furthermore, a limit block 113 may be provided on the substrate 111. The limit block 113 may be constructed in multiple ways, and the multiple limit blocks 113 may be spaced apart on the substrate 111. The limit block 113 can abut against the tray 112, thereby restricting the movement of the tray 112.

[0062] As some embodiments of this application, the motor stator and rotor assembly equipment 10 includes a two-hand start button 19. By pressing the two-hand start button 19, the drive device 15 can receive a signal and drive the drive end 151, thereby causing the first shape changing plate 1311 and the second shape changing plate 1411 to slide on the slide rail 121, thereby achieving the effect of controlling the movement of the first push rod 1313 and the second push rod 1413.

[0063] In some embodiments of this application, a first positioning pin 1111 is provided on the substrate, and a first positioning hole 1123 is provided on the tray. The tray 112 is fixed to the substrate 111 by the first positioning pin 1111 and the first positioning hole 1123, and the tray 112 is fixed to the substrate 111 by the first fastener 17, so that the tray 112 can be fixed in a suitable position on the substrate 111. A second positioning pin 1124 is provided on the tray 112, and a second positioning hole is provided on the motor housing. By assembling the second positioning pin 1124 and the second positioning hole, the motor housing can be placed in a suitable position on the tray 112, and the motor housing is fixed in a suitable position on the tray 112 by the second fastener 18. In some embodiments of this application, the second fastener 18 can be constructed as a pressure plate 1122, thereby improving the stability of the motor housing.

[0064] As some embodiments of this application, the roller assembly 16 includes a roller 162 and a handle 161. The roller assembly 16 can be raised and lowered by rotating the handle 161. By setting the roller 162, the difficulty of moving the tray 112 on the substrate 111 can be reduced, and the relative friction between the tray 112 and the substrate 111 can also be reduced, thereby improving the service life of the tray 112.

[0065] The following is for reference. Figures 1-4This invention describes a method for assembling a motor using a motor stator and rotor assembly device according to an embodiment of the present invention. The motor stator and rotor assembly device is the aforementioned motor stator and rotor assembly device, which includes: a platform, a frame, a first support plate, and a second support plate. A base plate suitable for supporting a motor housing is provided on the platform. The frame is provided on the platform and a slide rail extending in the height direction is provided on the frame. The first support plate is located on one side of the base plate in the height direction and is slidably connected to the slide rail. A first limiting portion is detachably provided on the first support plate, and the first limiting portion can selectively abut against one end of the motor rotor. The second support plate is located on the other side of the base plate in the height direction and is slidably connected to the slide rail. A second limiting portion is detachably provided on the second support plate, and at least a portion of the second limiting portion passes through the base plate and can selectively abut against the other end of the motor rotor.

[0066] Currently, the manufacturing process of electric motors requires the rotor to be assembled into the stator. However, the assembly of the stator and rotor of an electric motor is usually done manually using simple tooling. Manual assembly cannot guarantee the positioning accuracy of the stator and rotor during assembly, which affects the fit of the bearings and the stop. Therefore, a stator and rotor assembly mechanism is usually used to assemble the stator and rotor of the motor. However, the existing stator and rotor assembly mechanism can only assemble the stator and rotor of the same model of motor. When assembling other models of motors, an additional stator and rotor assembly mechanism needs to be designed, which increases the cost.

[0067] like Figure 2 As shown, specifically, the motor stator and rotor assembly equipment includes a platform and a frame. The platform provides support for the entire equipment. Support feet can be provided at the bottom of the platform to ensure the overall stability of the motor stator and rotor assembly equipment and prevent the equipment from sliding relative to the ground, thereby improving the reliability of the equipment. A base plate can be provided on the platform. The base plate and the platform can be detachably connected by bolts or screws, or by snap-fit ​​or plug-in connection. The base plate can support the motor housing and also limit the movement of the motor housing, ensuring that the motor remains stationary relative to the base plate during stator and rotor assembly, so as to facilitate the assembly of the motor rotor and motor stator.

[0068] The frame can be mounted on a platform and can be used to install other parts in the equipment. The frame and the platform can be fixed together with bolts. The frame is provided with columns extending in the height direction, and the columns can be provided with slide rails. The first support plate and the second support plate can be connected to the slide rails and slide relative to the slide rails. Further, the first support plate can be located on one side of the substrate in the height direction, and the second support plate can be located on the other side of the substrate in the height direction. The first support plate is detachably provided with a first limiting part, which can selectively abut against one end of the motor rotor. It is understood that the first support plate and the first limiting part are detachably connected. For example, the first support plate and the first limiting part can be detachably connected by bolts or screws, and the first limiting part can selectively abut against one end of the motor rotor.

[0069] It should be noted that the first support plate can slide along the slide rail toward the motor housing to abut against one end of the first limiting part and the motor rotor. The second support plate is detachably provided with a second limiting part. For example, the second support plate and the second limiting part can be detachably connected by bolts or screws. At least a portion of the second limiting part can pass through the base plate, and the end of the second limiting part can selectively abut against the other end of the motor rotor. Similarly, the second support plate can slide along the slide rail toward the motor housing to abut against the other end of the motor rotor. Since the first support plate and the first limiting part are detachably connected, and the second support plate and the second limiting part are detachably connected, when assembling the stator and rotor of different models of motors, it is only necessary to replace the corresponding first and second limiting parts to meet the requirements of stator and rotor assembly. In a specific embodiment, both the first support plate and the second support plate are provided with sliders on the side facing the slide rail, and the sliders can be slidably connected to the slide rail.

[0070] In the actual assembly process, the motor housing is first placed on the base plate. The first and second support plates are moved so that the first and second limiting parts abut against the two ends of the motor rotor respectively. Then, the first and second support plates are moved again so that the motor rotor moves into the motor housing and is assembled with the stator. Then, the first and second limiting parts are separated from the two ends of the motor rotor. Finally, the motor housing is removed from the base plate to complete the assembly of the motor stator and rotor.

[0071] In short, the first tray and the first limiting part of the motor stator and rotor assembly equipment of this application embodiment are detachably connected, and the second tray and the second limiting part are detachably connected. Therefore, when assembling stators and rotors of different models of motors, it is only necessary to replace the first and second limiting parts of the corresponding models to meet the requirements of motor stator and rotor assembly. Moreover, by replacing the first and second limiting parts, the motor stator and rotor assembly equipment can also be applied to single motors and dual motors, improving the compatibility of the motor stator and rotor assembly equipment and reducing the cost of the equipment.

[0072] like Figure 2 and Figure 3 As shown, in some embodiments of this application, the first limiting portion may include a first changing plate, a first locking member, and a first push rod. The first changing plate may have a first mounting hole extending through it in the height direction. The first locking member may be disposed on the first changing plate and may correspond to the first mounting hole. The first push rod may be disposed through the first locking member and the first mounting hole. One end of the first push plate facing the substrate may abut against one end of the motor rotor. The first push rod may be detachably connected to the first locking member, thereby enabling replacement of the first push rod. For example, when applied to different models of single motors, the first push rod can be replaced to meet the size requirements of the motor rotor; when applied to different models of dual motors, the entire first changing plate can be replaced to meet the requirements.

[0073] In some embodiments of this application, the outer peripheral wall of the first push rod may be formed with a first threaded portion, and the inner peripheral wall of the first locking member may be formed with a second threaded portion. The second threaded portion can be threadedly engaged with the first threaded portion to connect the first push rod and the first locking member. The end of the first push rod away from the substrate may also be formed with a rocker arm portion, which can rotate axially to drive the first push rod as a whole to move in the height direction.

[0074] Understandably, after the motor housing is placed on the base plate, the motor rotor is initially positioned by moving the first and second support plates. After the second limiting part abuts against one end of the motor rotor, the operator can manually control the rocker arm to rotate the first push rod relative to the first locking member, thereby driving the first push rod to move in the height direction until the first push rod abuts against the other end of the motor rotor, thus clamping the motor rotor. Then, the first and second support plates are moved to move the motor rotor into the motor housing and assemble it with the motor stator.

[0075] like Figure 2 and Figure 3 As shown, in some embodiments of this application, the first limiting part further includes a guide post. The guide post can be disposed on the side of the first changing plate facing the substrate, and the guide post can extend in the height direction. The guide post can be connected to the first changing plate or the first locking member. The first push rod is disposed through the guide post, and the first top plate and the guide post can be fitted with a clearance. The guide post can play a guiding role, ensuring that when the operator operates the rocker arm, the first push rod can move in the height direction along the guide post, preventing the first push rod from deviating and ensuring the stability of the first push rod when it moves.

[0076] like Figure 2As shown, in some embodiments of this application, the second limiting part may include a second changing plate, a second locking member, and a second push rod. The second changing plate can be detachably connected to the second tray. In a specific embodiment, the second changing plate and the second tray can be connected by bolts. A second mounting hole extending through in the height direction can be formed on the second changing plate. The second locking member can be disposed on the second changing plate and can be correspondingly disposed with the second mounting hole. The second push rod can be disposed through the second locking member and the second mounting hole, and one end of the second push rod facing the substrate can abut against the other end of the motor rotor. The second push rod can be detachably connected to the second locking member. When applied to different models of single motors, the first and second push rods can be replaced to meet the size of the motor rotor. When applied to different models of dual motors, the first and second changing plates can be replaced to meet the requirements.

[0077] like Figure 2 As shown in some embodiments of this application, the motor stator and rotor assembly equipment may further include a drive device. The drive device may be mounted on a frame and has a drive end extending in the height direction. The drive end may pass through the first and second forming plates and be power-connected to the first and second forming plates. In a specific embodiment, the drive device may be a motor, and the drive end may be a connecting screw. The connecting screw may be threadedly connected to the first and second forming plates. The motor may drive the connecting screw to rotate, thereby causing the first and second forming plates to slide on the slide rail. The motor may be power-connected to a reduction mechanism to ensure that the rotational speed of the drive end meets the requirements.

[0078] Furthermore, a bearing housing can be provided on the frame. The bearing housing can be fitted onto the outer end of the drive end to ensure greater stability when the drive end rotates. The bearing housing can be connected to the frame through a fixing plate. For example, the bearing housing and the fixing plate can be connected by bolts. The fixing plate can extend in the width direction, and both ends of the fixing plate in the width direction can be connected to the frame by bolts. Multiple bearing housings can be constructed. Using multiple bearing housings can further improve the stability of the drive end.

[0079] like Figure 4As shown in some embodiments of this application, the motor stator and rotor assembly equipment may further include a tray. The tray may be disposed on a substrate and be movable relative to the substrate. A support surface may be formed on the tray. The support surface may be used to support the motor housing. A support block and a second fastener may be disposed on the support surface. The support block may be in contact with the bottom of the motor housing. In a specific embodiment, multiple support blocks may be constructed. Multiple support blocks may be spaced apart on the support surface. The support blocks may prevent wear between the motor housing and the tray. The support blocks may be constructed as rubber parts to reduce the vibration of the motor housing while increasing the friction between the motor housing and the tray, making the motor housing more stable during stator and rotor assembly. The second fastener may serve to fix the motor housing. Furthermore, a second push rod may be selectively inserted through the tray to ensure that the second push rod can penetrate the motor housing and abut against the motor rotor.

[0080] like Figure 4 As shown, in some embodiments of this application, a roller conveyor assembly can be provided between the substrate and the tray. The roller conveyor assembly can drive the tray to move on the substrate. For example, when the motor needs to be assembled with the stator and rotor, the roller conveyor assembly can drive the tray to the outer end. When the motor housing is placed on the tray, the tray is driven to move directly above the substrate to facilitate the assembly of the stator and rotor. Furthermore, a limit block can be provided on the substrate. The limit block can be constructed in multiple ways, and the multiple limit blocks can be spaced apart on the substrate. The limit block can abut against the tray to restrict the movement of the tray.

[0081] like Figure 1 As shown, the assembly method includes:

[0082] S1, control the second push rod to move downwards so that the second push rod moves below the substrate.

[0083] Among them, the assembly management program of the motor can be selected. Press the two start buttons, the drive device can receive the signal and drive the drive end, so that the first and second shape change plates slide on the slide rail. Since the second push rod is installed through the second locking member and the second mounting hole of the second shape change plate, the second push rod can move with the second shape change plate until the second push rod moves to the bottom of the base plate so that the second push rod can avoid the tray.

[0084] S2, place the motor housing on the tray on the transfer trolley.

[0085] The motor housing can be directly placed on a tray on a transfer trolley. Further, the tray on the transfer trolley can be provided with one of a second positioning pin and a second positioning hole, and the motor housing is provided with the other of the second positioning pin and the second positioning hole. As some embodiments of this application, the tray is provided with a second positioning pin, and the motor housing is provided with a second positioning hole. As some embodiments of this application, the tray is provided with a second positioning hole, and the motor housing is provided with a second positioning pin. By aligning the second positioning pin and the second positioning hole and assembling them, the motor housing can be placed in a suitable position on the tray of the transfer trolley. Furthermore, a second fastener is used to fix the motor housing to the tray, reducing the risk of the motor housing shifting on the tray or even falling off the tray.

[0086] S3, move the tray carrying the motor housing onto the base plate.

[0087] The tray carrying the motor housing can be moved onto the base plate manually or mechanically. As an example, the base plate can be equipped with a liftable roller conveyor assembly, which includes rollers and a handle. Rotating the handle rotates a camshaft within the roller conveyor assembly, thus lifting the assembly and enabling its lifting capability. The rolling motion of the rollers facilitates movement of the tray carrying the motor housing on the base plate. For instance, when the motor requires stator and rotor assembly, the roller conveyor assembly can move the tray to a suitable position on the base plate for assembly. Furthermore, the base plate can be equipped with limit stops. Multiple limit stops can be spaced apart on the base plate. When the tray carrying the motor housing moves to the suitable position on the base plate, the limit stops abut against the tray, restricting its movement and effectively positioning the tray.

[0088] S4. Control the second push rod to move upward to the preset position so that the second push rod passes through the through hole and extends into the motor housing.

[0089] The driving device receives signals and drives the driving end to control the second push rod to move upward to a preset position, so that the second push rod can pass through the through hole and extend into the motor housing, thereby further positioning the motor housing. Specifically, the base plate is provided with one of the first positioning pin and the first positioning hole, and the tray is provided with the other of the first positioning pin and the first positioning hole. As some embodiments of this application, the base plate is provided with the first positioning pin, and the tray is provided with the first positioning hole. As some embodiments of this application, the base plate is provided with the first positioning hole, and the tray is provided with the first positioning pin. Align the first positioning pin and the first positioning hole, rotate the handle to control the roller assembly to descend, so that the first positioning pin and the first positioning hole are fitted together, and use the first fastener to fix the tray to the base plate, thereby fixing the tray in a suitable position on the base plate. The driving device receives signals and drives the driving end, so that the first changing plate and the second changing plate slide on the slide rail, and the second push rod moves again with the second changing plate until the second push rod passes through the through hole and extends into the motor housing, thereby achieving the effect of further positioning the motor housing.

[0090] S5. Insert the first push rod through the motor end cover, place the motor rotor on the second push rod, move the first push rod down to abut against the motor rotor, and move the motor end cover down so that the bearing on the motor rotor is assembled into the bearing hole of the motor end cover.

[0091] In this design, a first push rod is inserted through a motor end cover, which may have a perforated structure. The first push rod is inserted through this perforated structure to secure it to the motor end cover. The motor rotor is placed on a second push rod, causing it to abut against the second push rod. The first push rod can be manually moved downwards to abut against the motor rotor, and the motor end cover can be moved downwards to assemble the bearing on the motor rotor into the bearing hole of the motor end cover, thus achieving a mating effect between the motor end cover and the motor rotor. As an example, the outer peripheral wall of the first push rod may have a first threaded portion, and the inner peripheral wall of the first locking member may have a second threaded portion. The second threaded portion can thread-mate with the first threaded portion to connect the first push rod to the first locking member. A rocker arm may also be formed at the end of the first push rod away from the base plate, allowing the rocker arm to rotate axially, thereby moving the entire first push rod in the height direction.

[0092] The first push rod is inserted through the motor end cover, and the motor rotor is placed on the second push rod, so that the end of the second push rod near the first push rod abuts against the motor rotor. The rocker arm is rotated to move the first push rod relative to the first locking member along the height direction of the motor stator and rotor assembly, thereby lowering the first push rod until it abuts against the motor rotor. The motor end cover is then lowered so that the bearing on the motor rotor is fitted into the bearing hole of the motor end cover, thus achieving the effect of assembling the motor end cover and the motor rotor.

[0093] S6. Control the first and second push rods to move down synchronously to drive the motor end cover and motor rotor to the target position, and assemble the motor end cover and motor housing together.

[0094] The drive unit receives signals and drives the drive end, controlling the first and second push rods to move synchronously downwards. This moves the motor end cover and motor rotor to the target position, where the motor end cover and motor housing are assembled, allowing for smooth assembly. For example, pressing the start button again activates the drive unit, which receives signals and drives the drive end, causing the first and second changing plates to slide on the slide rail and controlling the first and second push rods to move synchronously downwards. The first and second push rods then move the motor end cover and motor rotor to the target position, where they are assembled with the motor housing. The motor end cover and motor housing are then bolted together to complete the motor assembly.

[0095] It should be noted that the drive unit is equipped with a very high-precision pressure sensor with a set pressure upper limit. This sensor is used to detect the pressure generated when the stator and rotor are attracted to each other during the process of the motor rotor entering the motor housing. If the pressure exceeds the pressure upper limit, the motor stator and rotor assembly equipment will automatically alarm and stop operating to improve the safety of the stator and rotor assembly process.

[0096] S7. Remove the first push rod and control the second push rod to move downwards so that the second push rod moves below the substrate.

[0097] The first push rod can be manually removed, and the drive device can receive a signal and drive the drive end to control the second push rod to move downward, so that the second push rod moves below the substrate, allowing the second push rod to avoid the tray again. Further, by rotating the rocker arm to remove the first push rod from the first locking member, and pressing the two-hand start button, the drive device receives a signal and drives the drive end, causing the first and second shape-changing plates to slide on the slide rail. The second push rod moves with the second shape-changing plate until it moves below the substrate, allowing the second push rod to avoid the tray again.

[0098] S8. Move the tray containing the motor housing back to the transfer trolley.

[0099] In this process, the pallet carrying the motor housing is manually moved back to the transfer trolley. As an example, by removing the first fastener and turning the handle, the camshaft inside the roller conveyor assembly can be rotated, causing the roller conveyor assembly to lift the pallet, thus removing the first locating pin from the first locating hole. The pallet carrying the motor housing can then move on the base plate under the action of the rollers, facilitating its return to the transfer trolley.

[0100] Specifically, the assembly management program of the motor can be selected. Press the two start buttons and the drive device can receive the signal and drive the drive end, so that the first and second shape change plates slide on the slide rail. Since the second push rod is installed through the second locking member and the second mounting hole of the second shape change plate, the second push rod can move with the second shape change plate until the second push rod moves to the bottom of the base plate so that the second push rod can avoid the tray.

[0101] The pallet on the transfer trolley may be provided with one of a second positioning pin and a second positioning hole, and the motor housing is provided with the other of the second positioning pin and the second positioning hole. As some embodiments of this application, the pallet is provided with a second positioning pin, and the motor housing is provided with a second positioning hole. As some embodiments of this application, the pallet is provided with a second positioning hole, and the motor housing is provided with a second positioning pin. By aligning the second positioning pin and the second positioning hole and assembling the second positioning pin and the second positioning hole, the motor housing can be placed in a suitable position on the pallet of the transfer trolley. Furthermore, a second fastener is used to fix the motor housing to the pallet.

[0102] A liftable roller assembly can be installed on the base plate. The roller assembly includes rollers and a handle. By rotating the handle, the camshaft inside the roller assembly rotates, thereby lifting the roller assembly and achieving the effect of lifting the roller assembly. The rolling arrangement of the rollers facilitates the movement of the tray carrying the motor housing on the base plate. For example, when the motor needs to be assembled with its stator and rotor, the roller assembly can move the tray directly above the base plate to facilitate the assembly. Furthermore, limit blocks can be installed on the base plate. Multiple limit blocks can be constructed and spaced apart on the base plate. When the tray carrying the motor housing moves to a suitable position on the base plate, the limit blocks abut against the tray, thereby restricting the movement of the tray and facilitating the positioning of the tray carrying the motor housing.

[0103] The substrate is provided with one of a first positioning pin and a first positioning hole, and the tray is provided with the other of a first positioning pin and a first positioning hole. In some embodiments of this application, the substrate is provided with a first positioning pin, and the tray is provided with a first positioning hole. In some embodiments of this application, the substrate is provided with a first positioning hole, and the tray is provided with a first positioning pin. The first positioning pin and the first positioning hole are aligned, and the handle is rotated to control the roller conveyor assembly to descend, so that the first positioning pin and the first positioning hole are engaged and assembled. A first fastener is used to fix the tray to the substrate, thereby fixing the tray in a suitable position on the substrate. The driving device can receive signals and drive the driving end, so that the first and second forming plates slide on the slide rail, and the second push rod moves again with the second forming plate until the second push rod passes through the through hole and extends into the motor housing, thereby achieving a further positioning effect on the motor housing.

[0104] The outer peripheral wall of the first push rod may have a first threaded portion, and the inner peripheral wall of the first locking member may have a second threaded portion. The second threaded portion can be threadedly engaged with the first threaded portion to achieve the effect of connecting the first push rod and the first locking member. The end of the first push rod away from the substrate may also have a rocker arm portion, which can rotate axially, thereby driving the first push rod as a whole to move in the height direction.

[0105] The first push rod is inserted through the motor end cover, and the motor rotor is placed on the second push rod, so that the end of the second push rod near the first push rod abuts against the motor rotor. The rocker arm is rotated to move the first push rod relative to the first locking member along the height direction of the motor stator and rotor assembly, thereby lowering the first push rod until it abuts against the motor rotor. The motor end cover is then lowered so that the bearing on the motor rotor is fitted into the bearing hole of the motor end cover, thus achieving the effect of assembling the motor end cover and the motor rotor.

[0106] Press the start button again, and the drive device can receive the signal and drive the drive end, so that the first and second shape changing plates slide on the slide rail and control the first and second push rods to move down synchronously. The first and second push rods can drive the motor end cover and the motor rotor to the target position, that is, the motor end cover and the motor rotor can be assembled with the motor housing. The motor end cover and the motor housing are screwed together by bolts to complete the motor assembly.

[0107] It should be noted that the drive unit is equipped with a very high-precision pressure sensor with a set pressure upper limit. This sensor is used to detect the pressure generated when the stator and rotor are attracted to each other during the process of the motor rotor entering the motor housing. If the pressure exceeds the pressure upper limit, the motor stator and rotor assembly equipment will automatically alarm and stop operating to improve the safety of the stator and rotor assembly process.

[0108] Rotate the rocker arm to remove the first push rod from the first locking member, press the two-hand start button, the drive device receives the signal and drives the drive end, so that the first and second shape change plates slide on the slide rail, and the second push rod moves with the second shape change plate until the second push rod moves to the bottom of the base plate so that the second push rod can avoid the tray again.

[0109] After removing the first fastener, the camshaft inside the roller conveyor assembly can be rotated by turning the handle, thereby lifting the pallet and causing the first locating pin to move out of the first locating hole. The pallet carrying the motor housing can then move on the base plate under the action of the rollers, which facilitates the return of the pallet carrying the motor housing to the transfer trolley.

[0110] It should be noted that multiple first and second push rods can be provided. As some embodiments of this application, when it is necessary to assemble dual motors, two first and two second push rods can be provided. Along the height direction of the motor stator and rotor assembly equipment, the two first push rods move synchronously, and the two second push rods move synchronously. By providing two first and two push rods and changing the positions of the support block and the second fastener on the tray so that the positions of the support block and the second fastener are adapted to the corresponding dual motor housings, the effect of assembling the dual motor stator and rotor can be achieved.

[0111] Furthermore, the first and second changing plates are detachable. When it is necessary to assemble the stator and rotor of different models of motors, the first and second changing plates can be replaced to meet the assembly requirements of different models of motors. By replacing the first and second changing plates, the first and second push rods can be replaced synchronously so that the first and second push rods meet the corresponding dimensions of the motor stator and rotor. Thus, the motor stator and rotor assembly equipment can be applied to single or dual motors of different models.

[0112] Therefore, the assembly method of this application can improve the accuracy of motor stator and rotor assembly, thereby improving the quality of the finished motor and increasing the assembly efficiency. Furthermore, by replacing the first and second shape-changing plates, the first and second push rods can be replaced simultaneously, ensuring that the first and second push rods meet the corresponding dimensions of the motor stator and rotor. This allows the motor stator and rotor assembly equipment to assemble stators and rotors of various motor specifications, improving the compatibility of the equipment and reducing the assembly cost of motors of different specifications.

[0113] In some embodiments of the present invention, a liftable roller assembly is provided on the substrate, and moving a tray carrying a motor housing onto the substrate includes: controlling the roller assembly to rise, moving the tray from the transfer trolley onto the roller assembly, and then controlling the roller assembly to descend so that the tray and the substrate are in contact.

[0114] The roller conveyor assembly includes rollers and a handle. Rotating the handle rotates the camshaft within the assembly, causing the cam to lift the assembly, thus enabling it to be raised and lowered. The rolling motion of the rollers facilitates the movement of a tray carrying a motor housing on the substrate. For example, when the motor requires stator and rotor assembly, the rollers on the assembly can move the tray directly above the substrate for assembly. Furthermore, the substrate can be equipped with multiple limit stops, spaced apart. When the tray carrying the motor housing moves to a suitable position on the substrate, the limit stops abut against the tray, restricting its movement and effectively positioning it. Rotating the handle again rotates the camshaft within the assembly, causing it to descend and bring the tray into contact with the substrate.

[0115] In some embodiments of the present invention, the substrate is provided with one of the first positioning pin and the first positioning hole, and the tray is provided with the other of the first positioning pin and the first positioning hole. Moving the tray from the transfer trolley to the roller assembly includes: making the first positioning pin and the first positioning hole face each other in the height direction.

[0116] In some embodiments of this application, a first positioning pin is provided on the substrate, and a first positioning hole is provided on the tray. This application will describe an example where the substrate has a first positioning pin and the tray has a first positioning hole. Along the height direction, the first positioning pin and the first positioning hole are positioned opposite each other. This arrangement allows the first positioning hole to avoid the first positioning pin. When the handle is rotated to control the roller assembly to descend, the risk of interference between the first positioning pin and the tray is reduced, thereby allowing the tray and the substrate to fit together smoothly. This achieves the effect of fixing the tray in a suitable position on the substrate, which is beneficial to improving the stability during the assembly of the motor stator and rotor.

[0117] In some embodiments of the present invention, moving the tray carrying the motor housing onto the substrate further includes: fixing the tray to the substrate using a first fastener and fixing the motor housing to the tray using a second fastener.

[0118] In some embodiments of this application, the first fastener can be configured as a quick-release bolt. In some embodiments of this application, the first fastener can be configured as a pressure plate. By using the first fastener to fix the tray to the base plate, the stability of the tray can be improved. In some embodiments of this application, the second fastener can be configured as a bolt. In some embodiments of this application, the second fastener can be configured as a pressure plate. By using the second fastener to fix the motor housing to the tray, the stability of the motor housing relative to the tray can be improved. During the stator and rotor assembly process of the motor, the stability of the motor housing can be improved, thereby improving the assembly accuracy and contributing to the improvement of the quality of the finished motor.

[0119] In some embodiments of the present invention, the tray is provided with one of the second positioning pin and the second positioning hole, and the motor housing is provided with the other of the second positioning pin and the second positioning hole. Placing the motor housing on the tray on the transfer trolley includes: manually placing the motor housing on the tray and making the second positioning pin pass through the second positioning hole.

[0120] In some embodiments of this application, a second positioning pin is provided on the tray, and a second positioning hole is provided on the motor housing. This application will describe an example where a second positioning pin is provided on the tray, and a second positioning hole is provided on the motor housing. Along the height direction, the second positioning pin and the second positioning hole are positioned opposite each other. When the motor housing is manually placed on the tray, the second positioning hole can avoid the second positioning pin, reducing the risk of interference between the second positioning pin and the motor housing. By having the second positioning pin pass through the second positioning hole, the motor housing can be placed in a suitable position on the tray. After the tray is transferred to the base plate, the second push rod can be reliably inserted into the motor housing, thereby achieving the effect of accurate assembly of the motor's stator and rotor.

[0121] In some embodiments of the present invention, the pallet is provided with a support block, and placing the motor housing on the pallet on the transfer trolley includes: manually placing the motor housing on the support block so that the support block supports the motor housing.

[0122] The process involves manually placing the motor housing onto a tray, and then manually placing it onto a support block on the tray. The second positioning hole avoids the second positioning pin, reducing the risk of interference between the second positioning pin and the motor housing. By inserting the second positioning pin through the second positioning hole, the motor housing can be positioned appropriately on the tray. The second positioning pin and the support block jointly support the motor housing, improving its stability and reducing the risk of damage at stress concentration points due to uneven stress distribution, thereby enhancing safety during motor assembly.

[0123] In some embodiments of the present invention, a first push rod is inserted through the motor end cover, the motor rotor is placed on the second push rod, the first push rod is moved down to abut against the motor rotor, and the motor end cover is moved down to assemble the bearing on the motor rotor into the bearing hole of the motor end cover. This includes: installing the first push rod on a frame, then inserting the first push rod through the motor end cover and placing the motor rotor on the second push rod, and rotating the first push rod to move it down and fix it to the motor rotor.

[0124] In some embodiments of this application, the outer peripheral wall of the first push rod may have a first threaded portion, and the inner peripheral wall of the first locking member may have a second threaded portion. The second threaded portion can be threadedly engaged with the first threaded portion to connect the first push rod to the first locking member, thereby achieving the effect of mounting the first push rod on the stand. Then, the first push rod is inserted through the motor end cover, and the motor rotor is placed on the second push rod so that the motor rotor abuts against the second push rod. The end of the first push rod away from the substrate may also have a rocker arm portion. The rocker arm portion can rotate axially, and rotating the rocker arm portion can drive the first push rod to move in the height direction, causing the first push rod to move down and be fixedly connected to the motor rotor, thereby clamping the motor rotor between the first and second push rods, reducing the risk of the motor rotor moving or even falling off.

[0125] In some embodiments of the present invention, the assembly of the motor end cover and the motor housing includes: applying sealant to the assembly surfaces of the motor housing and the motor end cover, and using a third fastener to fix the motor end cover and the motor housing.

[0126] In this process, sealant is applied to both the mounting surfaces of the motor housing and the motor end cover. This seals the gap between the motor housing and the motor end cover after assembly, improving the motor's sealing performance, ensuring stable operation of the stator and rotor, and ultimately extending the motor's service life. As some embodiments of this application, the third fastener can be a bolt. Using the third fastener to secure the motor end cover and motor housing facilitates reliable assembly, thus completing the motor assembly.

[0127] In some embodiments of the present invention, moving a pallet carrying a motor housing back to a transfer trolley includes: removing a first fastener, controlling the roller conveyor assembly to rise and lift the pallet, and then moving the pallet from the substrate back onto the transfer trolley.

[0128] After the motor is assembled, the first fastener is removed to disassemble the tray and the base plate. Turning the handle rotates the camshaft within the roller conveyor assembly, causing the roller conveyor assembly to lift the tray, allowing the first locating pin to move out of the first locating hole. The tray carrying the assembled motor can then move on the base plate under the action of the rollers, facilitating the return of the tray to the transfer trolley.

[0129] According to an embodiment of the present invention, a computer-readable storage medium is stored thereon in which a combined motor assembly management program is stored. When the combined motor assembly management program is executed by a processor, it implements the assembly method of the above embodiment.

[0130] According to embodiments of the present invention, a computer-readable storage medium stores a motor assembly management program, which can perform stator and rotor assembly on motors of various specifications, thereby improving the compatibility of motor stator and rotor assembly equipment and reducing the assembly cost of motors of different specifications.
