Technical Field

[0002] The rotor magnetic tile is generally glued to the rotor yoke, or it is wrapped and sealed to the rotor yoke with a bulk molding compound. The production process of the plastic-sealed rotor is to first manually place the magnetic tiles in the mold piece by piece, then put the rotor yoke on the magnetic tile, then put the spline keypad in the center of the rotor, and finally inject the bulk molding compound to wrap it and heat it to make the rotor. It takes a lot of time to manually place the magnetic tiles in the mold piece by piece, especially for motors with a large number of poles. The efficiency of manual placement of magnetic tiles is extremely low. This process has become the shortcoming of large-scale batch production of external rotor permanent magnet motors by enterprises, seriously affecting their production efficiency. At the same time, there is often a phenomenon that the magnetic tiles are damaged due to excessive force when placing them, and the magnetic tiles collide with the mold, which not only causes material waste, but also affects the performance of the motor, resulting in a decrease in the motor qualification rate; in addition, the existing magnetic tile installation method has a low degree of automation and insufficient installation accuracy.

[0003] In order to solve the deficiencies of the existing technology, people have conducted long-term exploration and proposed various solutions.

[0027] The lifting drive assembly 3 provides lifting driving force for the pressing and positioning structure 6 , and the magnetic shoes are placed in sequence in the magnetic shoe positioning channel 11 , and the upper end surface of the rotor housing 4 is kept flush with the end surface of the magnetic shoe positioning channel 11 .

[0028] Among them, the positioning base 1 is arranged in a ring shape, and is provided with a plurality of fixed connection holes 13 for positioning the positioning base 1 to the ground. The assembly frame 2 includes a plurality of supporting uprights 21, the bottom of the supporting uprights 21 is fixedly connected to the positioning base 1 and the upper end is provided with a motor mounting cross plate 22.

[0029] It can be seen that the clamping and positioning structure 6 includes an inner top pressing seat 61 arranged in a ring shape, the inner top pressing seat 61 is clamped on the circumferential outer side of the rotor shell 4, and the inner top pressing seat 61 is circumferentially provided with a plug-in top pressing portion 62 for pressing the magnetic tile, the rotor shell 4 is circumferentially provided with an installation slot 41 for installing the magnetic tile, and the installation slot 41 is corresponding to the plug-in top pressing portion 62, and the bottom of the plug-in top pressing portion 62 is arranged one by one corresponding to the magnetic tile positioning channel 11.

[0030] The magnetic shoe in the magnetic shoe positioning channel 11 is driven by an external push rod. When the magnetic shoe is aligned with the bottom of the plug-in pressing portion 62, the external push rod stops moving.

[0031] Furthermore, a linkage positioning sleeve 63 is provided on the inner top pressure seat 61, a top pressure channel 64 is provided on the axis of the linkage positioning sleeve 63, and a lifting guide part 65 is provided circumferentially thereon, a strip travel limit groove 66 is longitudinally provided on the lifting guide part 65, and the strip travel limit groove 66 is connected to the inner top pressure seat 61 through a linkage screw 67.

[0032] The cooperation between the strip travel limit groove 66 and the linkage screw 67 is not only used to limit the lifting and lowering of the inner top pressure seat 61, but also can drive the linkage positioning sleeve 63 to rise synchronously when the inner top pressure seat 61 rises to the highest position of the strip travel limit groove 66.

[0033] Specifically, the lifting drive assembly 3 includes a servo drive motor 31 arranged on the motor mounting horizontal plate 22, and the output end of the servo drive motor 31 is provided with a lifting rotation drive shaft 32, and the axis of the lifting rotation drive shaft 32 is provided with a threaded connection channel 33 for inserting one end of the linkage rotor shaft 5, and the bottom of the lifting rotation drive shaft 32 is provided with a plurality of plug-in connecting rods 34.

At this time, the servo drive motor 31 is started to drive the lifting and rotating drive shaft 32 to descend, and the lifting and rotating drive shaft 32 is pressed into the pressing channel 64 and presses the inner pressing seat 61. The inner pressing seat 61 is pressed down, and the plug-in pressing part 62 presses the magnetic tile located on the lower side into the corresponding installation slot 41 of the rotor shell 4. The servo drive motor 31 drives the lifting and rotating drive shaft 32 to rise and drives the linkage positioning sleeve 63 to rise synchronously. At this time, the lifting and rotating drive shaft 32 is rotated to rotate and change the position of the rotor shell 4, so that the installation slot 41 without the magnetic tile installed is aligned with the magnetic tile positioning channel 11. The above operation is repeated to press the magnetic tile. After completion, the lifting and rotating drive shaft 32 rotates and rises, and the linkage rotor shaft 5 is passively disengaged, and an external manipulator is used to switch the workpiece.
