Description

Automatic paint rolling device for stator

Technical Field

The utility model belongs to the technical field of motor production, and particularly relates to an automatic stator paint rolling device.

Background

The rust-proof treatment of the stator surface is an important process in the manufacturing process of the motor stator, which directly affects the service life of the motor. At present, the stator is mainly rusted by means of antirust paint on the surface of the stator, and the setting of the antirust paint is generally realized by paint spraying or paint rolling.

The painting process typically sprays paint to the rotating stator surface with a spray gun or atomizer. When spraying, the antirust paint is sprayed on the surface of the rotor in a mist form, and a large amount of paint mist can cause harm to human bodies. When the paint mist concentration is too high and the air circulation is not smooth, safety accidents such as fire disaster and the like are easy to happen. In order to ensure the health and production safety of operators, the inner and outer surfaces of the stator are painted by a paint rolling process.

The paint roller device has various structural forms: for example, chinese patent publication No. CN216757046U discloses a stator paint rolling apparatus, in which a stator spreading mechanism spreads a stator and drives the stator to rotate in a paint box, so that an insulating paint is adhered to an outer wall of the stator, and a heating mechanism heats the rotating stator, so that the insulating paint can be cured rapidly. Because the stretching mechanism contacts with the inner wall of the stator, paint rolling on the inner wall of the stator cannot be realized, and the paint layer finished by the paint rolling mode is easy to have uneven thickness, so that the use and the installation of the stator are affected.

In order to make the paint layer thickness of the stator even, chinese patent publication No. CN113083602a discloses a paint roller device for irregular surface of stator core, the device makes the paint roller scrape paint attached to the paint roller to different extent by adjusting the interval between the paint scraping wheel and the paint roller, and then controls the thickness of paint layer attached to the paint roller, finally achieves the purpose of controlling the thickness of paint layer on the surface of the stator core. The paint rolling device for the irregular surface of the stator core comprises an iron core outer circle paint rolling device and an iron core inner circle paint rolling device, wherein the iron core outer circle paint rolling device comprises a rotary supporting mechanism which is matched with an inner hole of the iron core and drives the iron core to rotate along the axis of the iron core, and the iron core inner circle paint rolling device comprises a stator rotary limiting mechanism which is in clearance fit with the outer peripheral surface of the iron core. When the device works, the iron core firstly completes the outer circle paint rolling operation on the rotary supporting mechanism of the iron core outer circle paint rolling device, the iron core after completing the outer circle paint rolling is manually taken down, then is carried and sleeved on the second paint rolling wheel of the iron core inner circle paint rolling device, and after completing the inner circle paint rolling operation on the stator rotary limiting mechanism of the iron core inner circle paint rolling device, the iron core is manually taken down and then is put into a tray to enter the next working procedure.

Because the stator core and the stator have similar structures, the device is also suitable for the paint rolling process of the inner and outer circumferential surfaces of the stator. In the process of using the device, manual operation is needed for carrying and loading and unloading the stator, so that not only is the manpower wasted, but also the risk that the operator is clamped by the device exists, and safety accidents are easy to occur.
