Varnish stoving device for new energy automobile spare part machining and varnish stoving method of varnish stoving device

Abstract

The invention discloses a varnish stoving device for new energy automobile spare part machining and a varnish stoving method of the varnish stoving device. The varnish stoving device comprises a varnish stoving device body; the front side, the rear side and the middle of the interior of the varnish stoving device body are provided with a cooling bin, a dehumidification bin and a varnish stoving bin respectively; varnish stoving lamps are arranged on the left side and the right side of the inner wall of the varnish stoving bin correspondingly; and the outer surface of the varnish stoving device body is fixedly connected with a waste heat utilization mechanism. Primary dehumidification and drying can be carried out in advance through waste heat flowing out of the interior of the varnish stoving bin, the adhesion of varnish surfaces is improved, the situation that the varnish surfaces of spare parts sag, reworking is carried out, and the production qualification rate of the spare parts is affected is avoided, water vapor generated in the varnish stoving bin flows out along with air flow, redundant water vapor is condensed out for centralized collection, air and working environment pollution is avoided, the internal humidity of the varnish stoving bin can be greatly reduced, and the spare parts are comprehensively baked, so that the varnish surface stoving efficiency is improved, and the productivity of the spare parts is prevented from being influenced.

Description

technical field [0001] The invention relates to the technical field of auto parts processing, in particular to a paint baking device and a paint baking method for processing new energy auto parts. Background technique [0002] In industrial production, most of the spare parts will go through the painting process during the production process, and the natural drying efficiency of the paint surface is low. The irradiation lamp irradiates the paint surface with high temperature to accelerate the evaporation of water in the paint surface, thereby improving the drying efficiency of the paint surface. [0003] In the existing patent (publication number: CN112547454A), a paint-baking device for processing new energy auto parts is disclosed, which turns over the parts to the other side through the turning device, which is convenient for processing the other side, and uses the vibration device to turn the parts to the other side. The moisture on the spare parts is shaken down, which...

AI Technical Summary

Problems solved by technology

In the above-mentioned prior art, the above-mentioned device will drive the spare parts to vibrate, which will cause the problem of paint sagging on the paint surface of the spare parts, which will greatly affect the quality of the paint spraying of the spare parts. The water vapor evaporated from the surface will gather in it, so that the internal humidity is always at a high level, resulting in a greater impact on the drying efficiency of spare parts, thereby affecting the production capacity of spare parts, and it has no effect on the cooling of spare parts. Liquid nitrogen is used for rapid cooling, which is likely to cause cracks on the paint surface and increase production costs
