[0002] An electric motor transfers electrical energy to the stator to form a rotational force. The stator core is a support for carrying the stator coil, generating a pole magnetic field to enable the motor to rotate. When the motor is operating normally, due to the action of current, magnetic flux will be generated in the stator coil, and these magnetic fluxes are generated by the stator core. Therefore, the stator core is an important part of the motor, directly affecting the operating efficiency and performance of the motor.

[0023] When preparing to sleeve the plastic sleeve, by passing a plurality of stator cores 35 through the plurality of stator core placement holes 22 opened in the turntable 21 one by one and clamping them with the stator core clamping protrusions 34 on the top of the push plate 33 in the stator core placement holes 22, the plurality of stator cores 35 are kept stable. By starting the brushless motor 24 and controlling the rotation speed of the brushless motor 24, the stator core placement holes 22 are rotated one by one to the lower part of the sleeving mechanism 16 and can stop rotating each time they rotate to the lower part of the sleeving mechanism 16.

[0024] Such as Figure 3As shown in the figure, several vertical plates 211 are fixedly installed in an annular array at the eccentric position on the top of the turntable 21. The several vertical plates 211 are respectively located on one side of several stator core placement holes 22 away from the center of the turntable 21.

[0025] By respectively rotating the knobs 214 on one side of the several vertical plates 211 to drive the threaded rods 213 in the threaded holes 212 to rotate, the hanging plates 215 on their outer walls move forward. After the stator core is clamped on the stator core clamping convex block 34 and the stator core 35 lapped with the flipping arc-shaped plate 223 is clamped and fixed by the arc-shaped clamping plate 218, the preparatory work is completed. After the top parts of several stator cores 35 are all clamped into the stator core plastic sleeves 165 in one round, several electric push rods 32 can be started first to drive the pushing disk 33 to drive the stator core clamping convex block 34 to descend and separate from the stator core 35. The stator core 35 remains stationary under the clamping of the arc-shaped clamping plate 218 and the flipping arc-shaped plate 223. Then, the flipping motor 222 in the motor compartment 221 is started, so that the stator core 35 is driven to flip 180 degrees by the movable connection between the arc-shaped clamping plate 218 and the hanging plate 215, making its bottom upward. Then, the electric push rod 32 is started again to drive the pushing disk 33 and the stator core clamping convex block 34 to be inserted into the bottom of the stator core 35, and so on. By using the rotating turntable 21, the stator core plastic sleeves 165 are installed one by one, and the stator core plastic sleeves 165 are respectively sleeved on the other side of the stator core 35, and finally the sleeving on both sides of the stator core 35 is completed.

[0027] Start the lifting motor 12 on the top of the L-shaped base 1 to drive the lifting screw 13 to rotate in the lifting slot 11, and cooperate with the threaded connection between the lifting screw 13 and the lifting block 14 to make the lifting block 14 drive the lifting plate 15 to move downward, and use the plastic sleeve positioning protrusion 163 to clamp the outer ring 164 and the stator core plastic sleeve 165 at the bottom of the positioning plate 162 in advance. When the lifting plate 15 moves downward, the connecting column 161 will be used to drive the positioning plate 162 to move downward, so that the stator core plastic sleeve 165 is stuck at the top of the stator core 35.

[0028] The working principle of the stator core plastic sleeve insertion device is described in detail below.

[0029] like Figures 1-5As shown in the figure, when preparing to put on the plastic sleeve, several stator cores 35 are passed through several stator core placement holes 22 formed in the turntable 21 one by one, and are clamped with the stator core clamping bumps 34 on the top of the pushing plate 33 in the stator core placement holes 22, so that several stator cores 35 are kept stable. Then, the knobs 214 on one side of several vertical plates 211 are rotated respectively to drive the rotation of the threaded rods 213 in the threaded holes 212, so that the hanging plates 215 on their outer walls move forward, and the stator cores 35 that are clamped on the stator core clamping bumps 34 and are lapped with the flipping arc plates 223 are squeezed and fixed by the arc-shaped clamping plates 218 to complete the preparation work. Then, the brushless motor 24 is started and the rotation speed of the brushless motor 24 is controlled, so that the stator core placement holes 22 are rotated one by one to the lower part of the sleeving mechanism 16. Each time it rotates to the lower part of the sleeving mechanism 16, it can stop rotating, and the lifting motor 12 on the top of the L-shaped base 1 is started to drive the lifting screw rod 13 to rotate in the lifting chute 11. In cooperation with the threaded connection between the lifting screw rod 13 and the lifting block 14, the lifting block 14 drives the lifting plate 15 to move downward. And the outer ring 164 of the plastic sleeve and the stator core plastic sleeve 165 are previously clamped at the bottom of the positioning plate 162 by the plastic sleeve positioning bumps 163. When the lifting plate 15 moves downward, it will drive the positioning plate 162 to move downward by the connecting column 161, so that the stator core plastic sleeve 165 is clamped on the top of the stator core 35. After the stator core plastic sleeves 165 are all clamped on the tops of several stator cores 35 in one round, several electric push rods 32 can be started first to drive the pushing plate 33 to drive the stator core clamping bumps 34 to descend and separate from the stator cores 35.

Then, the flipping motor 222 in the motor cabin 221 is started, and the stator cores 35 are driven to flip 180 degrees by the movable connection between the arc-shaped clamping plates 218 and the hanging plates 215, so that their bottoms face upward. Then, the electric push rod 32 is started to drive the pushing plate 33 and the stator core clamping bumps 34 to be clamped into the bottoms of the stator cores 35, and so on, using the rotating turntable 21, and the stator core plastic sleeves 165 are installed one by one, and the stator core plastic sleeves 165 are respectively sleeved on the other side of the stator cores 35, and finally the sleeving on both sides of the stator cores 35 is completed.
