Description

[0002] The insulation paper is always used for the insulation of the electric drive motor stator, the insulation paper has poor high-temperature resistance and short service life, and is prone to cause the insulation performance to decrease; and is not conducive to large-scale assembly line operation. In the motor stator processing process, in order to improve the quality performance of the motor stator and slow down the oxidation rate of the motor stator, the motor stator needs to be subjected to paint spraying treatment, so in the motor manufacturing industry, applying rust-proof paint to the surface of the motor stator has become the most popular rust-proof treatment method. The stator coil powder coating is a very important process link. At present, the stator coating is mainly manually coated with powder, and this operation mode not only has low efficiency, uneven powder coating, poor dust removal effect, but also has certain safety hazards, and the powder coating qualified rate is low.

[0003] There are many production jigs and automatic devices for applying rust-proof paint to the motor stator, such as a paint spraying device for motor stator processing disclosed in the authorized announcement No. CN210729912U and authorized announcement date of June 12, 2020, which comprises a paint bucket, a motor, a rotating shaft, a hydraulic cylinder, a bearing frame, an auxiliary roller, a top plate, a liquid pump, a liquid spraying pipe and a discharge plate, characterized in that a notch is arranged on the side wall of the paint bucket, the motor is arranged on the outer wall of the paint bucket, the rotating shaft is arranged in the paint bucket, the hydraulic cylinder is arranged on the outer wall of the paint bucket, the bearing frame is arranged on the piston rod, the auxiliary roller is provided with a connecting shaft at both ends, the top plate is arranged on the stand column, the liquid pump is arranged on the top plate, the liquid spraying pipe penetrates through the fixed plate at both ends, and the discharge plate is arranged on the inner wall of the paint bucket at one end. The paint is conveyed into the liquid spraying pipe through the liquid pump, and sprayed out through the nozzle, so that the sprayed paint is sprayed onto the surface of the motor stator rotating with the rotating roller to perform paint spraying treatment on the motor stator, thereby improving the work efficiency and the paint spraying quality of the motor stator.

[0004] After the existing motor stator is subjected to paint application treatment, if the paint layer is moved without drying, the paint layer is prone to be scraped off. In the above prior art, the rotation of the rotating roller is used to control the rotation of the stator so that the surface of the stator is subjected to paint spraying treatment, but after the surface of the motor stator is sprayed with paint, the paint layer is likely to be scraped by the rotating roller due to the fact that the paint layer is not dried in time, thereby causing defective products.
