Abstract

The invention discloses a method and a device for painting the surface of a punched sheet of a stator core, belonging to the technical field of high-voltage motors. The method includes: tilting the yoke of the punching sheet at a set angle; using the first upper rubber roller and the first lower rubber roller arranged in parallel and tangential to the cylindrical surface to paint the surface of the punching sheet; Extrude the second upper rubber roller and the second lower rubber roller to carry out the coating of punching section. The device includes a control mechanism and a painting head. The control mechanism is used to control the painting head. The painting head includes a first pair of rubber rollers and a second pair of rubber rollers. The first upper rubber roller and the first lower rubber roller, the first upper rubber roller and the first lower rubber roller are used for painting the punching surface; The second upper rubber roller and the second lower rubber roller, the second upper rubber roller and the second lower rubber roller are used for painting the punching section. The coating rate of the stator core punching sheet can be effectively improved, and the painting rate is high.

Description

technical field [0001] The invention relates to the technical field of high-voltage motors, in particular to a method and device for painting the surface of stator core punching sheets. Background technique [0002] High-voltage motor stator core punching is a very important part of the motor, and the surface of each core punching sheet needs to be coated with a layer of insulating varnish. [0003] At present, most motor manufacturers use organosilicon steel sheet paint for surface coating of stator core punching. This paint has good electrical properties, but the heat resistance and heat shrinkage of the paint are relatively poor. High, and organic silicon steel sheet paint heat curing will produce toluene, xylene and other organic waste gas, which is not environmentally friendly. [0004] Therefore, under the general situation of increasing emphasis on environmental protection, domestic and foreign motor manufacturers have successively begun to conduct research on the co...
