Description

TECHNICAL FIELD

[0001] The present application relates to the field of enameled wire production and processing, and particularly relates to a new energy automobile resistant corona composite enameled wire coating device and method. BACKGROUND

[0002] Enameled wire refers to metal wires coated with insulating paint for winding electromagnetic coils, also known as electromagnetic wire.

[0003] In the existing enameled wire painting operation, when a certain thickness of paint layer is needed, a felt painting method is usually used. However, the felt painting method is not suitable for enameled wire paint with too fast solvent evaporation or too high viscosity. Both too fast evaporation and too high viscosity can quickly block the pores of the felt, losing its good elasticity and capillary siphon ability. When a certain thickness of paint layer is painted by spraying, multiple spraying is needed to achieve the required thickness of the paint layer. However, the multiple spraying production line for one-time forming has a high cost, and when the required paint layer is thin, the equipment function will be wasted. When the multiple spraying production line is not used, the wire paint layer cannot be formed at one time, reducing the quality of wire production.

[0009] Further, the unwinding assembly comprises an unwinding frame, a unwinding roller is rotatably installed on the unwinding frame, and an unwinding guide roller is rotatably arranged on the unwinding frame near the spraying assembly; in this way, the unwinding guide roller prevents the wire from being bent when entering the spraying assembly.

By using the first insulation ring and the second insulation ring, hot air in the baking can is prevented from entering the spray box.

[0016] A method for using a corona-resistant composite enameled wire coating device for new energy vehicles, the method comprising the following steps:

[0017] S1. First, select a guide tube with an appropriate guide groove specification based on the wire thickness, and a paint scraping tube with an appropriate paint scraping chamber specification based on the thickness of the spray paint. Also, select the corresponding number of spraying components and baking components based on the number of spraying passes. After completing the selection, thread the guide tube and paint scraping tube onto the spraying component. The unwinding component, spraying component, baking component, and winding component are positioned and spliced ​​together using limit bars and limit connectors. During splicing, the other side of the paint scraping tube is inserted into the first connection port, and the guide tube on the spraying component located between the two baking components is inserted into the second connection port.

[0018] S2. The unprocessed wire is unwound by the unwinding assembly, and the wire passes through the unwinding guide roller and the guide tube into the spray assembly, and the wire is sprayed with paint by the nozzle in the spray assembly;

[0019] S3. After the painting operation, the wire enters the baking assembly through the paint scraping tube. When the paint scraping tube passes through, the excess paint is scraped off during the painting operation. The painted wire is then baked by the baking assembly to evaporate and solidify the paint on the wire.

[0020] S4. After the roasting operation, the wire is introduced into the spraying assembly through the guide pipe for paint spraying operation, and then introduced into the baking assembly for baking operation, and the process is repeated until the required paint thickness is sprayed, and the last spraying operation is thinner than the previous paint thickness, and then after baking through the baking assembly, the wire is wound through the winding assembly.

[0021] The beneficial effects of the present application are embodied in:

[0022] In the present application, the spraying assembly and the baking assembly are spliced by the limiting strip and the limiting connecting block. When spraying different thickness of paint layers, the number of spraying assemblies and baking assemblies can be freely set. When processing different thickness of paint layers, one-time forming effect can be achieved. When processing thinner paint layers, the number of spraying assemblies and baking assemblies can be reduced, thereby reducing the equipment use cost and improving the production quality of equipment processing.

[0023] In the present application, the spraying assembly and the baking assembly are sealed by the use of the guide pipe and the paint scraping pipe. The wire is in a closed space during paint spraying and drying operation, which avoids the influence of external dust on the processing quality and the pollution of waste gas generated during processing to the external air. The paint scraping cavity and the paint scraping ring in the paint scraping pipe can scrape off the excess paint sprayed on the wire, so that the surface paint layer thickness of the wire after paint spraying is uniform.

[0024] In the present application, the paint scraping cavity is clamped on the paint scraping pipe through the clamping groove and the clamping rod, so that the paint scraping cavity can be replaced conveniently when the surface of the paint scraping cavity adheres more paint after long time use. The replacement is convenient and will not affect the production quality. The use of the first heat insulation ring and the second heat insulation ring avoids the hot gas in the baking pot entering the spraying box and affecting the spraying effect.
