Device and method for dipping of copper wire winding of automobile generator stator

Abstract

The invention discloses a device and method for varnishing a copper wire winding of an automobile generator stator. The device comprises a preheating transmission mechanism, an overall structure framecontaining high temperature furnaces, a varnishing device and a gelling and curing transmission mechanism after varnishing, wherein the preheating transmission mechanism before varnishing and the gelling and curing transmission mechanism after varnishing pass through the overall structure frame containing the high temperature furnaces side by side to be assembled together; and the varnishing device is connected with the overall structure frame containing the high temperature furnaces. The transmission mechanism disclosed by the invention achieves the effect of zero damage to a product in thetransmission process through a stable placement structure. According to the device and the method, the effect of zero damage to the product in the transmission process is achieved. A transporting technology, a baking technology and a varnishing technology for a product are separated in the technological process, so that an exhaust gas generated from volatilization of an insulating paint is easierto collect and thorough exhaust treatment is facilitated. Through the baking mode, of forming hot air circulation through heating air, of air drying components, the temperature of high-temperature regions is more uniform, meanwhile, the heat transfer efficiency of the air is significantly improved and the gelling and curing process quality is improved.

Description

technical field [0001] The invention relates to the technical field of automobile generators, in particular to a device and method for dipping copper wire windings of an automobile generator stator. Background technique [0002] Generators are widely used in the automotive industry. The stator of the generator needs to be dipped in paint, which is more important for the generator. The end of the stator coil of the generator receives a large electromagnetic force during operation. There are defects such as incomplete impregnation of paint and uneven paint film leading to lacquer bumps on the surface, and inter-turn short circuit may occur, which may cause safety accidents such as fire. [0003] Requirements and procedures for the production of auto generator stator copper wire winding varnish dipping process: the production of stator varnish dipping is completed in the order of stator preheating, winding varnish dipping (both ends), gelation, solidification, and cooling; the ...

Problems solved by technology

In the existing method, during the production process, because the V-shaped mechanism with a spring clamps the stator, the product will be dropped and the clamping position will change, which directly leads to a high scrap rate of the product; It is beneficial to the cleaning and maintenance of the paint supply system; the high-temperature box uses a black transistor to heat the ambient temperature, and the temperature of the thermostat is not uniform, resulting in poor gel effect, resulting in uneven paint layers with paint spots, and insulating paint dripping The situation is serious, which increases the difficulty of cleaning and also leads to the risk of fire in the high-temperature furnace. At the same time, the uneven temperature also leads to a low curing rate of the product; Increased gelation and curing time of the insulating varnish lead to low production efficiency; the irritating exhaust gas of the insulating varnish is not properly removed, resulting in a pungent smell in the workshop
