Description

Technical Field

[0001] The invention relates to the field of coil varnish dipping devices, and in particular to a coil varnish dipping device and a winding coil varnish dipping method for motor production. Background Art

[0002] Vacuum impregnation is an advanced coating process that involves placing the coil to be treated in a vacuum container and removing moisture, air and other volatile substances from the coil by vacuuming. Subsequently, insulating materials or coatings are filled into these spaces to improve the insulation performance, mechanical strength and moisture and mildew resistance of the final product. This process is particularly suitable for the treatment of precision parts such as electrical coils, micromotors, mutual inductors, power transformers, etc.

[0003] During the vacuum dipping process, the air needs to be evacuated before the paint is injected to ensure that the paint can better penetrate into the tiny gaps and pores of the coil. The order of this process is very important, as it can first extract moisture and impurities from the air to prevent moisture in the air from contaminating the paint.

[0004] Chinese patent application CN109980873A discloses a vacuum pressure impregnation device and a paint impregnation method thereof, comprising a paint impregnation tank, a paint delivery pipe and at least two paint impregnation bushings. Since the paint delivery pipe is used to input insulating paint from the top and flows downward through the overflow port, it is not necessary to fill the bottom of the paint impregnation tank first when the paint is input. Under the same paint impregnation conditions, the amount of paint required to be input is less, and by stacking at least two layers of paint impregnation bushings, at least two layers of motor stators can be impregnated at one time, and the paint impregnation efficiency is high. Chinese patent application CN105284037A discloses a varnish impregnation device and a varnish impregnation method, comprising a supporting mechanism, which holds the stator on the outer diameter side of the stator on which the stator coil is installed and supports the stator in a state where the axial direction of the stator is facing the horizontal direction, and the supporting mechanism is driven to rotate by a rotating device, thereby rotating the stator; a varnish dripping device, which drips varnish toward the coil end of the stator supported and rotated by the supporting mechanism; and a stator inner diameter side heating device, which can efficiently and effectively heat the stator on which the stator coil is installed on the stator core for varnish impregnation of the stator coil, and can prevent the varnish from adhering to the stator.

[0005] The above patents and prior art also have the following defects: At present, the paint dipping equipment needs to be vacuumed before injecting the paint liquid. Before and after each workpiece is dipped in paint, the cover needs to be opened to load and unload the materials, which destroys the internal vacuum environment. In order to prevent the adhesion of dust and the entry of moisture caused by large-area contact between air and paint liquid, vacuuming and paint liquid injection are required for each feeding, and paint liquid needs to be discharged for each discharge. The operation is cumbersome, resulting in long dip intervals and low dip efficiency. If a large-space dip painting equipment is used, multiple groups of workpieces are dipped in paint at one time, more paint liquid is required, the injection and discharge time of the paint liquid is long, and the economy is poor.

[0006] Therefore, the present application provides a coil varnishing device and a winding coil varnishing method for motor production to meet the needs. Summary of the invention
