[0019] A method for assembling a rotor of a direct-drive motor, comprising the rotor assembly mechanism of the direct-drive motor;

[0021] Step S1, placing the rotor housing on a positioning jig and fixing the positioning jig by a turntable assembly;

By driving the magnetic tile pressing module through the magnetic tile picking transmission module to pick up materials from the magnetic tile feeding tray and assemble them into the magnetic tile slots, precise control of the magnetic tile assembly process can be achieved, ensuring the accuracy and consistency of the assembly and improving the assembly precision. The setting of the magnetic tile picking transmission module makes the magnetic tile picking and pressing process more automated and efficient, which can improve the speed and efficiency of rotor assembly and reduce the cost and risk of manual operation.

Through the adjustment of the yoke material taking block and the pushing of the yoke pressing module in step S3, the stability and reliability of the rotor yoke during the assembly process are guaranteed, and possible misalignment or loosening during the assembly process is avoided. In step S4, the positioning jig is driven to rotate by the turntable assembly, thereby achieving multiple assembly of the rotor housing and forming magnetic tile slots on adjacent rotor magnetic tiles, thereby improving assembly accuracy and consistency. Through the operation of the magnetic tile material taking transmission module and the magnetic tile pressing module in step S5, the magnetic tiles are automatically taken and assembled, thereby reducing labor costs and improving assembly efficiency and stability.

[0059] See Figures 1 to 10 As shown, a rotor assembly method for a direct-drive motor includes the rotor assembly mechanism 20 of the direct-drive motor. The rotor assembly method includes the following steps:

[0060] Step S1, placing the rotor housing 101 on the positioning fixture 5 and fixing the positioning fixture 5 by the turntable assembly 2;

[0061] Step S2: The yoke feeding tray 31 is used to vibrate and feed the rotor yoke 102. The yoke picking transmission module 33 then drives the yoke grabbing module 34 to grab the rotor yoke 102 from the yoke feeding tray 31 and transfer the rotor yoke 102 to the top of the positioning fixture 5.

[0062] In step S3, the yoke grabbing module 34 drives the yoke grabbing connecting shaft 342 via the yoke grabbing motor 341 to adjust the rotor yoke 102 grabbed by the yoke grabbing block 344 so that the clamping positioning pin 3462 and the assembly positioning pin 1011 are coaxial. The rotor yoke 102 is then pushed from the yoke clamping groove 3461 to the inner circumference of the rotor housing 101 by the yoke pressing module 35 so that the assembly positioning groove 1021 slides into the assembly positioning pin 1011.

[0063] In step S4, after the rotor yoke 102 is assembled, the turntable assembly 2 drives the positioning fixture 5 to rotate to drive the rotor housing 101 to the next assembly positioning pin 1011, and then repeat step S3, sequentially performing multiple assembly steps, and forming magnetic tile slots 1022 on adjacent rotor magnetic tiles 103;

[0064] Step S5, when the assembly of the rotor yoke 102 is completed, one end is rotated to the bottom of the magnetic tile assembly component 4, and then the magnetic tile material picking transmission module 43 drives the magnetic tile pressing module 44 to pick up the material on the magnetic tile supply tray 41, and transfer it to the magnetic tile slot 1022 for assembly. After repeating the insertion of the rotor magnetic tile 103 into each magnetic tile slot 1022, the assembly of the motor rotor 10 is completed.

[0065] By placing the rotor housing 101 on the positioning jig 5 and fixing it in step S1, and using the turntable assembly 2 to fix the positioning jig 5, the rotor housing 101 is accurately positioned, ensuring the accuracy of the subsequent assembly steps. By operating the yoke feeding plate 31, the yoke material taking transmission module 33, the yoke grabbing module 34 and the yoke pressing module 35 in steps S2 and S3, the rotor yoke 102 is automatically taken and assembled, improving the assembly efficiency and consistency. By adjusting the yoke taking block 344 and pushing in the yoke pressing module 35 in step S3, the stability and reliability of the rotor yoke 102 during the assembly process are guaranteed, avoiding possible misalignment or loosening during the assembly process. In step S4, the positioning jig 5 is driven to rotate by the turntable assembly 2, thereby realizing multiple assemblies of the rotor housing 101 and forming magnetic tile slots 1022 on adjacent rotor magnetic tiles 103, improving the assembly accuracy and consistency. Through the operation of the magnetic tile retrieving and transmission module 43 and the magnetic tile press-fitting module 44 in step S5, automated retrieving and assembly of the magnetic tiles is achieved, reducing labor costs and improving assembly efficiency and stability. The present invention can achieve technical effects such as precise positioning, automated assembly, stable and reliable assembly, improved assembly accuracy, automated magnetic tile assembly, and process optimization.
