Description

Technical Field

[0001] The present invention belongs to the technical field, and particularly relates to a device for impregnating, curing and drying a motor stator. Background Art

[0002] The functions of the device for impregnating, curing and drying a motor stator include the following points:

[0003] 1. Improve insulation performance: After impregnation and curing, the paint liquid fills the gaps in the stator winding, enhancing the insulation performance and preventing short circuits and electric leakage.

[0004] 2. Enhance mechanical strength: The cured paint liquid makes the winding and the iron core combine more tightly, improving the overall mechanical strength and reducing vibration and noise.

[0005] 3. Improve heat dissipation: After the paint liquid fills the gaps, the heat conduction efficiency of the winding is improved, which helps with heat dissipation and extends the service life of the motor.

[0006] 4. Moisture and corrosion protection: The paint film can effectively isolate moisture and corrosive substances, protecting the winding from environmental damage.

[0007] 5. Improve durability: The cured paint film enhances the wear resistance and anti-aging ability of the winding, improving the durability of the motor.

[0008] Traditional devices for impregnating, curing and drying a motor stator include oven equipment, impregnating equipment and paint removal equipment. However, these devices operate independently of each other, resulting in the independent operation of the impregnating, curing and drying processes for the motor stator.

At the same time, the equipment cost is high, and the maintenance and operation costs are also relatively high. Moreover, the process is complex, and the impregnating and curing processes have high process requirements. Improper operation may affect the product quality.

From the dipping connection position to the oven (baking), 4. Paint expelling, 5. From the oven to the offline connection position (cleaning and shoveling connection position).

[0053] The technological process is as follows:

[0054] Take out the tray 4 from the oven - Transport the tray 4 to the oven connection position - The truss manipulator 52 grabs the product and places it on the tray 4 - Send it into the oven for pre-baking - Take out the product after baking - Transport it to the dipping connection position (send the tray 4 back to the oven or pick up the product coming out of dipping) - Dip the product - Take out the tray 4 from the oven and send it to the dipping connection position - The truss robot places the product on the tray 4 - The RGV picks up the tray 4 and puts it into the oven for baking - Perform paint expelling according to the technological requirements - After baking - Take out the product from the oven - Move to the cleaning connection position - Send the tray 4 to the oven.
