[0002] The main parts of the motor include the housing, stator and rotor. When assembling the motor, the stator needs to be fixed inside the housing first, and then the rotor is installed in the center of the stator and spaced apart. The fixing method between the stator and the housing is generally interference fit, so the installation method between the housing and the stator is often heat-fitted.

[0027] It should be noted that the terms "first", "second", etc. in the description and claims of the present application are used to distinguish similar objects, and are not necessarily used to describe a specific order or sequence.

[0028] In this application, unless otherwise clearly specified and limited, the terms "installed", "connected", "connected", "fixed" and the like should be understood in a broad sense, for example, it can be connected, detachably connected, or integrated; it can be mechanically connected or electrically connected; it can be directly connected or indirectly connected through an intermediate medium, it can be the internal connection of two elements or the interaction relationship between two elements. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0030] The terms "including" and "having" and any variations thereof in the specification and claims of the present application are intended to cover non-exclusive inclusions. For example, a process, method, system, product or apparatus comprising a series of steps or units is not necessarily limited to those steps or units explicitly listed, but may include other steps or units not explicitly listed or inherent to these processes, methods, products or apparatuses.

[0031] One of the preferred embodiments of the present application is as follows: Figure 1 As shown, a motor automatic assembly system includes an assembly table 1, a heating component 4, a gripping mechanism 3 and a positioning mechanism 2. The gripping mechanism 3 is installed on one side of the assembly table 1, and the gripping mechanism 3 can sequentially grip the housing 01 and the stator 02 for motor assembly to the assembly table 1. The positioning mechanism 2 is installed in the middle of the assembly table 1, and the positioning mechanism 2 can position and clamp the housing 01 from the inner side. During the assembly process of the stator 02 and the housing 01, when the stator 02 is placed in the housing 01, the positioning mechanism 2 can lift the housing 01 to disengage the positioning, so that the stator 02 is installed at the set position of the housing 01 under the action of gravity; the heating component 4 can heat the housing 01.

[0032] It should be known that when assembling the housing 01 and the stator 02, thermal installation is generally adopted; that is, the housing 01 is heated to a set temperature, and then the inner cavity size of the housing 01 is increased through thermal expansion, so as to achieve smooth placement and installation of the stator 02 and the housing 01.

[0033] It should be noted that, for ordinary motors, the housing 01 is cylindrical as a whole; while for special-shaped motors, the inner contour of the housing 01 is circular, and the outer contour is a non-circular special-shaped structure. When assembling ordinary motors, traditional assembly systems use the method of external positioning of the housing 01 to avoid interference with the placement of the stator 02; for the assembly of special-shaped motors, in order to avoid interference with the placement of the stator 02, a relatively regular area on the outer surface is generally selected for positioning. This results in the assembly of ordinary motors and special-shaped motors requiring two different assembly systems, that is, there is no commonality between the two, which will lead to an increase in assembly costs.

[0034] In the technical solution of the present application, since the housing 01 of the common motor and the special-shaped motor both have a circular inner contour structure, the present embodiment can adopt the method of internal positioning of the housing 01 to adapt to the assembly of the common motor and the special-shaped motor at the same time, thereby effectively improving the scope of application of the motor automatic assembly system of the present application. In addition, in order to ensure that the positioning mechanism 2 does not interfere with the placement of the stator 02 during the assembly of the stator 02 with the housing 01, the positioning mechanism 2 can lift the housing 01 when the stator 02 is placed in the housing 01, so that the housing 01 and the positioning mechanism 2 are out of position, thereby ensuring that the stator 02 and the housing 01 can be smoothly assembled without interference, thereby effectively improving the assembly efficiency of the motor.

[0035] In this embodiment, there are many specific structures of the grasping mechanism 3 that can grasp the housing 01 and the stator 02. For the sake of easy understanding, one specific structure will be described in detail below. Figure 1 As shown, the grabbing mechanism 3 includes a second rotating device 31, a grabbing arm 32, a magnetic sucker 33 and a clamp 34. The second rotating device 31 is vertically fixedly installed on one side of the assembly platform 1, and the grabbing arm 32 is vertically fixedly installed on the output end of the second rotating device 31, so that the grabbing arm 32 rotates under the drive of the second rotating device 31. The grabbing arm 32 is T-shaped, and the two ends of its horizontal extension are respectively installed with a magnetic sucker 33 and a clamp 34; the magnetic sucker 33 can grab the housing 01 by magnetic means, and the clamp 34 can grab the stator 02 by clamping.

[0036] It should be noted that the housing 01 is generally made of cast iron, and the stator 02 generally includes a stator core and a stator winding, and the stator winding is a copper coil wound on the stator core. This makes the end face of the stator 02 uneven, so it is not suitable for grasping by magnetic suction, but is grasped by a clamp 34; the specific structure and working principle of the clamp 34 are well-known technologies for those skilled in the art, so they are not elaborated in detail here; common clamps 34 can be hydraulically controlled, pneumatically controlled, and electrically controlled. The magnetic suction cup 33 adopts electromagnetic adsorption to generate magnetic force when the housing 01 is adsorbed, and loses power and magnetic force after the housing 01 is placed on the assembly table 1.

[0037] It should be known that the specific structure and working principle of the second rotating device 31 are well-known technologies to those skilled in the art, and therefore will not be elaborated in detail here; the common second rotating device 31 adopts a motor.

[0038] In this embodiment, there are many specific structures of the positioning mechanism 2 that can achieve the above functions. For the sake of easy understanding, the following will be described in detail using one specific structure. Figures 2 to 4 As shown, the positioning mechanism 2 includes a discharge table 22, a driving device and at least one pair of positioning components 23. The discharge table 22 is rotatably mounted on the assembly table 1 for placing the shell 01 to be assembled; the driving device is installed on one side of the assembly table 1 to drive the discharge table 22 to rotate, and then the shell 01 placed on the discharge table 22 can rotate synchronously with the discharge table 22, so that the heating component 4 can evenly heat the shell 01. The positioning components 23 are installed at equal intervals along the circumferential direction at the bottom of the discharge table 22, so that the positioning and clamping of the inner wall of the shell 01 can be achieved by the synchronous separation of multiple positioning components 23. The positioning component 23 can be driven and cooperated with the assembly table 1, so that in the process of the positioning component 23 rotating synchronously with the discharge table 22, according to the different rotation circles of the discharge table 22, the positioning component 23 sequentially positions and lifts the shell 01 through the driving cooperation with the assembly table 1.

[0039] It is understandable that the different rotations of the unloading table 22 have different driving degrees for the positioning component 23; thus, the positioning component 23 can perform corresponding actions according to the different driving degrees. Specifically, the positioning component 23 rotates with the unloading table 22, and it should first move horizontally and then move vertically; the horizontal movement is used to position and clamp the shell 01, and the vertical movement is used to lift the shell 01.

[0040] It should be known that the specific number of the positioning components 23 can be designed according to the actual needs of those skilled in the art, for example Figure 2 and Figure 3As shown, there are three positioning assemblies 23 , and the three positioning assemblies 23 are arranged at intervals of 120° along the circumferential direction of the unloading platform 22 .

[0041] In this embodiment, there are multiple specific structures of the driving device that can drive the unloading table 22 to rotate. For the sake of easy understanding, one of the structures will be described in detail below. Figure 2 As shown, the driving device adopts a first rotating device 21, a main gear 211 is installed at the output end of the first rotating device 21, and a gear 221 meshing with the main gear 211 is arranged on the outer side of the unloading platform 22, so that the unloading platform 22 rotates under the drive of the first rotating device 21. It should be known that the specific structure and working principle of the first rotating device 21 are well-known technologies for those skilled in the art, so they will not be elaborated in detail here; the common first rotating device 21 adopts a motor.

[0042] In this embodiment, there are many specific structures of the positioning component 23 that can achieve the above functions. For the sake of easy understanding, the following will be described in detail using one of the structures. Figures 2 to 4 As shown, a main bevel gear 24 is fixedly installed in the middle of the assembly platform 1 below the unloading platform 22, and a radially extending guide groove 220 is provided on the unloading platform 22, and the guide groove 220 corresponds to the number and position of the positioning assembly 23. The positioning assembly 23 includes a first screw rod 231, a positioning component and a top plate 234; the first screw rod 231 is rotatably installed on the unloading platform 22 and extends radially, and the first screw rod 231 is driven and matched with the main bevel gear 24 through the secondary bevel gear 2311 installed at the end. The positioning component is matched and installed on the first screw rod 231 and extends to the upper end surface of the unloading platform 22 along the corresponding guide groove 220. The top plate 234 is vertically slidably installed on the unloading platform 22 and cooperates with the positioning component through a traction structure. The positioning component can move outward from the middle of the unloading platform 22 along the guide groove 220 under the rotation drive of the first screw rod 231, and then position and clamp the inner wall of the placed shell 01. After the stator 02 is placed in the inner cavity of the housing 01 , the positioning component can continue to lift the top plate 234 through the traction structure under the rotation drive of the first screw rod 231 , and then the housing 01 partially supported on the top plate 234 is lifted.

[0043] It is understandable that there are many specific structures of the positioning component that can achieve the above functions. For example, the positioning component can adopt a split structure, in which part of the structure is used to position and clamp the shell 01, and the other part is used to cooperate with the top plate 24 and lift it up. The positioning component can also adopt a deformable structure, that is, after the positioning component positions and clamps the shell 01, as the first screw rod 231 continues to be driven, the positioning component can continue to maintain contact with the shell 01 in the horizontal direction through elastic deformation, and at the same time, the positioning component can lift the shell 01 in the vertical direction. Of course, the positioning component can also be a combination of a split type and elastic deformation. For the sake of ease of understanding, it will be described in detail below through specific examples.

[0044] Specifically, Figure 4 and Figure 6 As shown, the positioning component includes a positioning block 232 and a traction block 233; the positioning block 232 and the traction block 233 are both installed in cooperation with the first screw rod 231, the positioning block 232 is used to position and clamp the housing 01, and the traction block 233 and the top plate 234 are matched through the traction structure. When the housing 01 is positioned and clamped, the positioning block 232 and the traction block 233 are driven by the first screw rod 231 to move in the direction close to the inner wall of the housing 01 until the positioning block 232 is against the inner wall of the housing 01. When the stator 02 is placed in the housing 01, the first screw rod 231 continues to drive the positioning block 232 to move in the direction close to the inner wall of the housing 01. At this time, the positioning block 232 can adopt a specific structure to remain stationary, or it can be elastically deformed, so that the positioning block 232 remains in contact with the inner wall of the housing 01; at the same time, the traction block 233 will continue to move and drive the top plate 234 through the traction structure to lift the housing 01.

[0045] It is understandable that the positioning block 232 of the elastic deformation structure can be a pressure block with a horizontal elastic sliding installation at the upper end, and the positioning block 232 elastically clamps the shell 01 through the pressure block. Therefore, when the traction block 233 drives the top plate 234 to lift the shell 01, the pressure block and the shell 01 remain stationary in the horizontal direction, and the remaining structure of the positioning block 232 will continue to move. For the specific structure in which the positioning block 232 directly remains stationary, a clutch structure can be adopted, that is, the positioning block 232 can be disengaged from the first screw rod 231 through the clutch structure after being positioned and pressed with the shell 01, so that only the traction block 233 performs the corresponding action when the first screw rod 231 continues to rotate. Since the positioning accuracy of the shell 01 by elastic clamping is relatively poor, the positioning of the shell 01 in this embodiment is preferably a rigid structure, that is, the positioning block 232 preferably adopts a clutch structure to cooperate with the first screw rod 231.

[0046] Specifically, Figure 6As shown, a clutch sleeve 2322 is rotatably installed in the middle part of the positioning block 232 through a clutch structure. The positioning block 232 is installed in cooperation with the first screw rod 231 through the clutch sleeve 2322, so that when the traction block 233 lifts the top plate 234, the clutch sleeve 2322 rotates synchronously with the first screw rod 231. At this time, the positioning block 232 is in a static state for maintaining the positioning of the housing 01 through the free state of the clutch structure.

[0047] In this embodiment, there are many specific structures of the clutch structure. For ease of understanding, a detailed description will be given below using one of the specific structures. Figure 6 and Figure 7 As shown, the clutch structure includes at least one clutch slot 2325 and at least one clutch block 2324; in order to ensure the stability of the clutch structure, the number of clutch slots 2325 and clutch blocks 2324 is preferably multiple, and the multiple clutch slots 2325 and clutch blocks 2324 can be arranged at equal intervals along the circumferential direction; the clutch block 2324 and the corresponding clutch slot 2325 can be elastically limited to set the resistance, and the specific limit resistance can be set according to the limit degree of the clutch block 2324 and the clutch slot 2325. There are two main specific ways to set the clutch groove 2325 and the clutch block 2324. One is that the clutch groove 2325 is set on the positioning block 232, and the clutch block 2324 is radially elastically slidably installed inwardly from the outside of the clutch sleeve 2322 through the spring 2323; the other is that the clutch groove 2325 is set on the outside of the clutch sleeve 2322, and the clutch block 2324 is radially elastically slidably installed on the inside of the rotational installation position of the positioning block 232 and the clutch sleeve 2322 through the spring 2323. Both of these settings can meet the requirements of this application, and those skilled in the art can choose according to actual needs.

[0048] It should be noted that when the housing 01 is lifted by the top plate 234, the positioning block 232 will slide vertically with the interior of the housing 01, which may cause scratches on the inner wall of the housing 01. Figure 5 As shown, a roller 2321 can be rotatably installed on the side of the positioning block 232 for contacting and pressing the housing 01, so that the positioning block 232 contacts the inner side of the housing 01 through the roller 2321. Then, when the housing 01 is lifted, the positioning block 232 can roll vertically along the inner wall of the housing 01 through the roller 2321, thereby effectively reducing resistance and preventing the inner wall of the housing 01 from being scratched. The material of the roller 2321 can be non-metal, preferably hard plastic.

[0049] In this embodiment, there are many specific structures of the traction structure that can achieve the above functions. For the sake of easy understanding, one of the structures will be described in detail below. Figure 4As shown, the traction structure includes a slide bar 2331 disposed on the traction block 233, and a horizontal slide groove 2343 and an oblique slide groove 2344 disposed on the top plate 234 and connected to each other. The slide bar 2331 can slide along the horizontal slide groove 2343 when the positioning block 232 positions the housing 01, so that the top plate 234 remains stationary in the vertical direction; the slide bar 2331 can slide along the oblique slide groove 2344 after the housing 01 completes the placement of the stator 02, thereby driving the top plate 234 to be lifted.

[0050] Specifically, Figure 4 As shown, the top plate 234 includes an L-shaped guide portion 2341 and a support portion 2342; the guide portion 2341 extends horizontally to be used to set a horizontal slide groove 2343 and an inclined slide groove 2344, and the guide portion 2341 is vertically set to support a part of the housing 01. In order to ensure the stability of the lifting of the top plate 234, the top plate 234 can be set in a frame shape, that is, the number of guide portions 2341 is two and they are arranged oppositely, and then the two opposite sides of the traction block 233 are provided with sliding rods 2331 to slide with the horizontal slide groove 2343 and the inclined slide groove 2344 on the guide portion 2341 on the opposite side.

[0051] In this embodiment, in order to ensure the heating efficiency of the heating component 4 on the housing 01, as shown in FIG. Figure 1 As shown, the heating component 4 can be extended into the housing 01 to heat it, so that in order to avoid interference with the installation of the stator 02 when the stator 02 is placed, the heating component 4 can be kept away from the housing 01 when the stator 02 is placed.

[0052] Specifically, Figure 8 As shown, the heating assembly 4 includes a mounting frame 41, a transmission assembly and a heating plate 45. The mounting frame 41 is fixedly mounted on one side of the assembly platform 1, the transmission assembly is vertically mounted on the mounting frame 41, the heating plate 45 is L-shaped and horizontally slidably mounted on the transmission assembly, the horizontal section of the heating plate 45 is matched with the guide groove 220 provided on the mounting frame 41 through a guide rod 451 provided on one side, and the guide groove 220 includes a vertical first groove section 411 and an inclined second groove section 412; the heating plate 45 can slide along the first groove section 411 and the second groove section 412 in sequence through the guide rod 451 under the drive of the transmission assembly to move away from the housing 01.

[0053] It can be understood that the second slot section 412 is located above the first slot section 411, and the second slot section 412 is tilted away from the heating plate 45. When the heating plate 45 heats the housing 01, the guide rod 451 is located at the smallest square of the first slot section 411. When the guide rod 451 slides along the first slot section 411 to the junction of the first slot section 411 and the second slot section 412, the heating plate 45 will be higher than the housing 01, and then the heating plate 45 will be away from the housing 01 in both the vertical and horizontal directions through the sliding of the guide rod 451 along the second slot section 412, so that there is no overlap between the projection of the heating plate 45 in the vertical direction and the housing 01, thereby ensuring that the stator 02 can be smoothly placed in the housing 01.

[0054] Specifically, there are many specific structures of the transmission assembly that can achieve the above functions. For the sake of easy understanding, one of the structures will be described in detail below.
