Abstract

The invention discloses a stator core punching sheet surface painting method and device and belongs to the technical field of high-voltage motors. The stator core punching sheet surface painting method comprises the following steps: inclining the yoke part of a punching sheet at a set angle; adopting a first upper rubber roller and a first lower rubber roller to paint the surface of the punching sheet, wherein the first upper rubber roller and the first lower rubber roller are parallel, and the cylindrical surface of the first upper rubber roller is tangent with that of the first lower rubberroller; and adopting a second upper rubber roller and a second lower rubber roller to paint the fracture surface of the punching sheet, wherein the second upper rubber roller and the second lower rubber roller are parallel and are in interference fit. The stator core punching sheet surface painting device comprises a control mechanism and a painting handpiece, wherein the control mechanism is usedfor controlling the painting handpiece; the painting handpiece comprises a first pair of rubber rollers and a second pair of rubber rollers; the first pair of rubber rollers comprises the first upperrubber roller and the first lower rubber roller, the first upper rubber roller and the first lower rubber roller are parallel and are used for painting the surface of the punching sheet, and the cylindrical surface of the first upper rubber roller is tangent with that of the first lower rubber roller; and the second pair of rubber rollers comprises the second upper rubber roller and a second lower rubber roller, the second upper rubber roller and the second lower rubber roller are parallel, are in interference fit and are used for painting the fracture surface of the punching sheet. With adoption of the stator core punching sheet surface painting method and device, the coating rate of the stator core punching sheet is effectively increased 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...
