Problems solved by technology

The poor effect of dipping paint will directly lead to the quality and safety performance of the motor coil. For example, if the effect of dipping paint is not good, the paint skin will fall off easily, and the wires will be exposed, which will cause inter-turn short circuit, cause safety hazards, and directly affect the product. the quality of
The existing varnish dipping process is not perfect, the paint film on the surface of the motor coil after varnish immersion is not uniform, and wrinkles, cracks and other phenomena often appear, which affect the overall performance and quality of the motor coil

Embodiment 1

[0022] A kind of washing machine motor coil dipping process that the present invention proposes comprises the following steps:

[0023] S1: Prepare materials and tools, including Group A paint liquid, Group B paint liquid, paint stirring rod, viscometer, automatic immersion machine and stopwatch, among which Group A paint liquid is 8411 solvent-free epoxy resin, and Group B paint liquid is 8411 A mixture of solvent-free epoxy resin, 8411-X thinner and release oil;

[0024] S2: Prepare the immersion liquid, mix the paint liquid of Group A and the paint liquid of Group B at room temperature with a weight ratio of 1:1, stir well with a paint stirring rod, and use a paint supply pump between the paint storage box and the immersion tank Backflow, during the preparation process, use a 4# Ford cup viscometer to detect the viscosity of the immersion liquid, and if the viscosity is too high, add a diluent to adjust the viscosity;

[0025] S3: Turn on the main power of the automatic im...

Abstract

The invention discloses a paint-immersion process for a motor coil of a washing machine. The paint-immersion process comprises the following steps of S1: preparing materials and tools; S2: preparing an immersion solution; S3: starting the general power supply of an automatic immersion machine, setting the voltage, choosing an automatic working mode, regulating the pitch time, and setting a preheating temperature; S4: starting a heater, an air heater and a circulating fan, enabling the automatic immersion machine to perform preheating and cooling operations, and putting a coil-inserting stator on the station of the automatic immersion machine after the cooling operation is finished; S5: performing operations of paint immersion, paint dripping, curing and workpiece taking-out; S6: removing residual paint by a scraper knife; S7: performing examination; and S8: switching off the power supply after the obtained workpiece is qualified through examination. The paint-immersion process provided by the invention is complete, and simple to operate; the surface of the immersed paint film is uniform without causing phenomena of cracks, wrinkles and exposed wires; and in addition, the paint film is firm and the paint does not fall off easily, so that high safety is achieved.

Description

technical field [0001] The invention relates to the technical field of motor coils, in particular to a paint impregnation process for washing machine motor coils. Background technique [0002] The varnish dipping process of the motor coil is a particularly important process in the preparation of the motor coil. The poor effect of dipping paint will directly lead to the quality and safety performance of the motor coil. For example, if the effect of dipping paint is not good, the paint skin will fall off easily, and the wires will be exposed, which will cause inter-turn short circuit, cause safety hazards, and directly affect the product. the quality of. The existing varnish dipping process is not perfect, the paint film on the surface of the motor coil after varnish dipping is not uniform, and wrinkles, cracks and other phenomena often appear, which affect the overall performance and quality of the motor coil. Contents of the invention [0003] The purpose of the present ...
