[0101] First, those skilled in the art should understand that these embodiments are merely for explaining the technical principles of this application and are not intended to limit the scope of protection of this application. Those skilled in the art can make adjustments as needed to adapt to specific application scenarios.

[0102] Secondly, it should be noted that, in the description of this application, unless otherwise expressly specified and limited, the terms "installation," "assembly," and "connection" should be interpreted broadly. For example, they can refer to a fixed connection, an indirect connection through an intermediate medium, or the internal connection of two components or the interaction between two components. Those skilled in the art can understand the specific meaning of the above terms in this application according to the specific circumstances.

[0103] Furthermore, it should be noted that in the description of this application, the terms "upper," "lower," "inner," "outer," etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are used only for the convenience of describing this application and simplifying the description, and do not indicate or imply that the equipment or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this application.

[0104] Furthermore, the terms "first," "second," "third," "fourth," and "fifth" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Thus, a feature defined as "first," "second," "third," "fourth," and "fifth" may explicitly or implicitly include one or more of that feature. In the description of this application, unless otherwise stated, "a plurality of" means two or more.

[0105] As illustrated in the background section, in related technologies, the stator 300 and rotor 200, as crucial internal components of the motor, directly affect the motor's performance, efficiency, and reliability through their assembly quality. The centers of the rotor 200 and stator 300 must be precisely aligned to ensure coaxiality. Excessive coaxiality deviation can lead to vibration and noise during motor operation, and even damage to the bearings. The assembly gap between the rotor 200 and stator 300 must be uniform and within design tolerances. Excessive gap reduces motor efficiency, while insufficient gap may cause friction or even collision between the rotor 200 and stator 300. The insulation layers of the rotor 200 and stator 300 must be intact to prevent short circuits and leakage. Damage to the insulation layers must be avoided during assembly. Some motors have stator 300 or rotor 200 with strong magnets, which can easily shift during assembly, further increasing the assembly difficulty.

[0106] Therefore, this application provides an assembly device 100 suitable for assembling a motor stator 300 and a rotor 200. The assembly device 100 provided in this application, by setting a positioning fixture 1 and a pressing assembly 2, includes at least one first positioning part 11. The first positioning part 11 abuts against the side of the gear 210 near the stator 300. The first positioning part 11 can fix the position of the rotor 200 when the stator 300 and rotor 200 are pressed together, preventing product defects due to positional misalignment, improving production efficiency and product quality, and enhancing the stability and reliability of the assembly device 100.

[0107] To make the objectives, technical solutions, and advantages of this application clearer, the technical solutions in the embodiments of this application will be described in more detail below with reference to the accompanying drawings. In the drawings, the same or similar reference numerals denote the same or similar components or components having the same or similar functions throughout. The described embodiments are some, but not all, of the embodiments of this application. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain this application, and should not be construed as limiting this application. All other embodiments obtained by those skilled in the art based on the embodiments of this application without creative effort are within the scope of protection of this application.

[0108] Reference Figures 1 to 7The assembly equipment 100 provided in this application embodiment is used to assemble a stator 300 and a rotor 200. The rotor 200 includes a gear 210. The assembly equipment 100 includes a positioning fixture 1 and a pressing assembly 2. The positioning fixture 1 includes a first positioning part 11, which abuts against the gear 210. The pressing assembly 2 is configured to push the stator 300 to move toward the rotor 200. The first positioning part 11 is configured to restrict the displacement of the rotor 200 when the pressing assembly 2 pushes the stator 300 to move.

[0109] The positioning fixture 1 is a mechanism in the assembly equipment 100 used to determine and maintain the position of the rotor 200. It ensures that during the assembly process, the rotor 200 can be accurately and stably positioned in a predetermined position, corresponding to the stator 300 to be installed. The positioning fixture 1 includes at least one first positioning part 11. The shaft of the rotor 200 has a gear 210 for power transmission. The first positioning part 11 can abut against the side of the gear 210 of the rotor 200 near the stator. The gear 210 of the rotor is blocked on one side of the first positioning part 11 and cannot move towards the stator 300. Therefore, the position of the rotor 200 connected to the gear 210 is fixed and will not shift towards the stator 300, which facilitates the pressing assembly 2 to press it in place. The positioning fixture 1 can ensure that the rotor 200 remains stable during processing or assembly, reduce product defects caused by position deviation, and facilitate the correspondence between the stator 300 and the rotor 200. After the stator 300 and the rotor 200 are aligned, the pressing assembly 2 can push the stator 300 to move relative to the rotor 200, thereby pressing the stator 300 and the rotor 200 together.

[0110] It should be noted that there may be one or more first positioning parts 11. The multiple first positioning parts 11 may be the same size or different sizes. This embodiment does not impose any restrictions on this.

[0111] By setting the positioning fixture 1 and the pressing component 2, the rotor 200 to be installed can be fixed in position during assembly, which improves production efficiency, ensures the accuracy of the pressing process, prevents product defects during pressing due to inadequate fixing, and improves product quality.

[0112] In some embodiments, the pressing assembly 2 comprises a fixed plate 21, a drive mechanism 22, a support column 23, a pressure plate 24, and a floating joint 25. The fixed plate 21 and the support column 23 support the drive mechanism 22, which drives the pressure plate 24 to move closer to the workpiece, thereby achieving the pressing of the stator 300 and the rotor 200. The design of the floating joint 25 allows for adjustment of angle and position within a certain range, thus providing greater flexibility and adaptability during the pressing process.

[0113] In some embodiments, the positioning fixture 1 includes a base 12, which has a through hole 121 through which the rotor gear 210 can pass.

[0114] The positioning fixture 1 includes a base 12 on which the rotor 200 can be placed. The base 12 is designed to conform to the shape of the rotor 200, so that the rotor 200 can be stably fixed on the base 12. The base 12 supports the bottom surface of the rotor 200 to prevent the product from tilting during feeding or pressing. The base 12 is provided with a through hole 121 through which the gear 210 of the rotor 200 can pass. Therefore, when the rotor 200 is placed on the base 12, the gear 210 of the rotor 200 passes through the through hole 121, so that the first positioning part 11 abuts against the gear 210 of the rotor 200, thereby positioning the rotor 200. When pressing, the first positioning part 11 abuts against the top of the gear 210 of the rotor 200, and the base 12 abuts against the bottom of the rotor 200, thus further positioning the rotor 200. During pressing, the first positioning part 11 can stably abut against the gear 210 without affecting the pressing assembly 2.

[0115] In some embodiments, the rotor 200 includes an end cap 220, the end cap 220 having a first through hole 230, and the base 12 having a second positioning part 122, the second positioning part 122 being located on the side of the base 12 near the rotor 200, the second positioning part 122 at least partially protruding from the base 12, and the second positioning part 122 being located within the first through hole 230.

[0116] The rotor 200 includes an end cover 220, which is part of the motor housing. The end cover 220 can prevent dust, iron filings, oil stains and other impurities from entering the rotor 200, protect the rotor 200 from external mechanical impact and collision, and ensure the stability of the rotor 200 during operation. The end cap 220 is provided with a first through hole 230, and the base 12 is provided with a second positioning part 122. The second positioning part 122 can be located at least partially in the first through hole 230. The second positioning part 122 is a protrusion located on the base 12, and the first through hole 23 is a hole on the end cap 220 corresponding to the protrusion. When the rotor 200 is located on the base 12, the second positioning part 122 on the base 12 passes through the through hole 121 of the end cap 220 of the rotor 200. The second positioning part 122 is fixed in the through hole 121. The end cap 220 can only move away from the base 12 and cannot move in the lateral direction. Therefore, the second positioning part 122 restricts the lateral movement of the rotor 200. At this time, the first positioning part 11 abuts against the gear 210 of the rotor 200, and the rotor 200 cannot move in the longitudinal direction. The position of the rotor 200 on the base 12 can be completely fixed.

[0117] It is understood that the first through hole 230 and the second positioning part 122 can be one or more, and this application does not impose too many restrictions.

[0118] In some embodiments, the positioning fixture 1 includes an elastic element 13, which abuts against the base 12.

[0119] The positioning fixture 1 is also provided with an elastic element 13, which abuts against the base 12. Therefore, when the pressing assembly 2 is pressed, the base 12 is supported by the elastic element 13 and can move up and down. It can absorb and compensate for dimensional tolerances through its own elastic deformation, which can solve the problem of large product tolerance deviation and prevent damage to the product during pressing.

[0120] In some embodiments, the positioning fixture 1 includes a drive member 14, which is configured to drive the first positioning part 11 to abut against the gear 210.

[0121] The positioning fixture 1 includes a drive member 14, which can drive the first positioning part 11 to abut against the gear 210. It is understood that the first positioning part 11 and the drive member 14 are fixedly connected. When the drive member 14 moves, it drives the first positioning part 11 to move, which can push the first positioning part 11 to abut against the side of the gear 210 with the action of the drive member 14, thereby restricting the movement of the rotor 200.

[0122] It is understood that the driving component 14 can be a cylinder, hydraulic cylinder, electric cylinder, motor, transmission structure, etc., and this application does not limit the type of driving component 14.

[0123] In some embodiments, the positioning fixture 1 includes a connector 15, a first positioning part 11 is disposed at one end of the connector 15, the first positioning part 11 extends toward the rotor 200, and the connector 15 is detachably connected to the drive member 14.

[0124] The positioning fixture 1 includes a connector 15. A first positioning part 11 is located at one end of the connector 15 and extends toward the rotor 200. The connector 15 can extend into the gap between the gear 210 and the end cover 220 of the rotor 200 and abut against the rotor 200. The drive member 14 is connected to the connector 15. Therefore, the drive member 14 drives the connector 15 to move, which in turn drives the first positioning part 11 to abut against the rotor 200. The connector 15 and the drive member 14 are detachably connected. Therefore, when the first positioning part 11 or the connector 15 is worn, the connector 15 can be disassembled and replaced without replacing other parts, which can significantly reduce maintenance costs.

[0125] It is understood that the connector 15 and the drive component 14 can be connected by threads, snap-fit ​​connections, etc. This application does not limit the connection method of the connector 15 and the drive component 14.

[0126] In some embodiments, the positioning fixture 1 further includes a positioning plate 16, which can abut against the stator 300 and is configured to be displaceable in the Z direction.

[0127] The positioning fixture 1 also includes a positioning plate 16, which can abut against the stator 300. During pressing, the rotor 200 is fixed by the base 12, and the stator 300 is supported by the positioning plate 16. The positioning plate 16 is floating and can move along the Z direction. Therefore, when the pressing assembly 2 presses down, the positioning plate 16 can adjust its position according to actual needs, thereby reducing problems caused by workpiece size tolerances or processing errors, ensuring the assembly accuracy of parts, buffering the pressing force, and avoiding workpiece deformation due to excessive force.

[0128] In some embodiments, the positioning plate 16 includes a clearance hole 161 through which the rotor 200 can pass.

[0129] The positioning plate 16 includes a clearance hole 161, the base 12 is located in the clearance hole 161, the rotor 200 can pass through the clearance hole 161 and be located on the base 12, and the stator 300 can be supported by the positioning plate 16 on the outer periphery of the rotor 200.

[0130] In some embodiments, the stator 300 is provided with a second through hole 310, and the positioning plate 16 is provided with a third positioning part 162. The third positioning part 162 is located on the side of the positioning plate 16 near the stator 300. The third positioning part 162 at least partially protrudes from the positioning plate 16 and can be at least partially located in the second through hole 310.

[0131] The stator 300 is provided with a second through hole 310, and the positioning plate 16 is provided with a third positioning part 162. The third positioning part 162 is a protrusion on the displacement positioning plate 16. The housing of the stator 300 is provided with a second through hole 310 corresponding to the protrusion. When the stator 300 is placed on the positioning plate 16, the third positioning part 162 is located in the second through hole 310. Therefore, the third positioning part 162 can limit the lateral displacement of the stator 300 and prevent the stator 300 from shifting during pressing.

[0132] It is understandable that the second through hole 310 and the third positioning part 162 can be one or more, and this application does not impose too many restrictions.

[0133] In some embodiments, the second positioning part 122 and the third positioning part 162 are pins.

[0134] In some embodiments, the positioning fixture 1 includes a first detection element 18 and a second detection element 19. The first detection element 18 is used to detect whether the rotor 200 is placed in place on the base 12, and the second detection element 19 is used to detect whether the stator 300 is placed in place on the positioning plate 16. After the rotor 200 is placed in place, subsequent processes are performed.

[0135] In some embodiments, the stator 300 includes a copper busbar 320, and the positioning fixture 1 further includes a positioning component 17, which includes a positioning groove, and the copper busbar 320 may be located in the positioning groove.

[0136] The stator 300 also includes a copper busbar 320, and the positioning fixture 1 also includes a positioning component 17. The positioning component 17 includes a positioning groove, in which the copper busbar 320 can be located. Therefore, the positioning groove can position the copper busbar 320 so that it corresponds with the rotor assembly hole 240. The copper busbar 320 of the stator 300 can pass through the rotor assembly hole 240. The copper busbar 320 is provided on the stator 300 housing assembly. During automatic high-speed assembly, it may be misaligned, crushed, or damaged. The positioning component 17 can ensure that the product is not damaged during automatic high-speed assembly production.

[0137] In some embodiments, the positioning component 17 includes a first positioning member 171 and a second positioning member 172, and the positioning groove includes a first positioning groove 173 and a second positioning groove 174. The first positioning groove 173 is located on the first positioning member 171, and the second positioning groove 174 is located on the second positioning member 172. The first positioning groove 173 and the second positioning groove 174 are arranged opposite to each other.

[0138] The first positioning member 171 is provided with a first positioning groove 173, and the second positioning member 172 is provided with a second positioning groove 174. The first positioning groove 173 and the second positioning groove 174 are arranged opposite to each other. Therefore, the first positioning groove 173 is located on one side of the copper busbar 320, and the second positioning groove 174 is located on the other side of the copper busbar 320, so that the copper busbar 320 is confined inside the first positioning groove 173 and the second positioning groove 174, and the positioning of the copper busbar 320 is more accurate.

[0139] In some embodiments, the first positioning member 171 includes a first driving member 1711, a first fixing block 1712, a connecting part 1713, and a first fixing rod 1714. The second positioning member 172 includes a second driving member 1721, a second fixing block 1722, and a second fixing rod 1723. The first driving member 1711 and the second driving member 1721 drive the first positioning groove 173 and the second positioning groove 174 to move closer to or away from the copper busbar 320. The first fixing block 1712 and the second fixing block 1722 are used to fix the first positioning member 171 and the second positioning member 172. The first fixing rod 1714 and the second fixing rod 1723 are used to fix the first positioning groove 173 and the second positioning groove 174. The connecting part 1713 is used to connect the first fixing rod 1714 and the driving member 14 so that the first positioning groove 173 and the second positioning groove 174 are misaligned, avoiding mutual interference when the first positioning groove 173 and the second positioning groove 174 are close to the copper busbar 320, and facilitating simultaneous correction of the copper busbar 320.

[0140] The steps for positioning the copper busbar 320 are as follows: before the stator 300 is installed into the positioning fixture 1, the first drive component 1711 drives the first positioning groove 173 to move to the position to be positioned, and then grabs the stator 300 and moves it downward to the assembly point; the second drive component 1721 then drives the second positioning groove 174 to move to the positioning position, and the stator 300 housing assembly moves downward into the rotor 200 hole. The first drive component 1711 and the second drive component 1721 are withdrawn at the same time to complete the positioning of the copper busbar 320.

[0141] In some embodiments, the assembly equipment 100 further includes a visual positioning component 173, which is configured to correspond the first through hole 230 of the rotor 200 to the first positioning element 171.

[0142] The visual positioning component 173 uses computer vision technology to quickly and accurately detect and identify information such as the position and posture of objects. The rotor 200 to be assembled is first moved to the visual positioning component 173 for visual positioning.
