Method for preventing gear panel from leaking light

Abstract

The invention discloses a method for preventing a gear panel from leaking light. The method comprises the following steps: step 1, spraying one layer of white paint on the front surface of a gear panel base material and spraying one layer of black paint; step 2, carrying out laser engraving on the position, which corresponds to the position needing light transmitting display of the gear panel, of the front surface of the gear panel base material; engraving the black paint to expose the white paint; spraying one layer of varnish; step 3, spraying one layer of the black paint on the back surface of the gear panel base material; step 4, carrying out the laser engraving on the position, which corresponds to the position needing light transmitting display of the gear panel, of the rear surface of the gear panel base material; engraving the black paint to expose the gear panel base material; and step 5, wiping a laser engraving region in the last step with a rough toluene solvent. The method has the beneficial effects that the black paint is sprayed on the rear surface of the gear panel so that a gap between the gear panel and an electronic module can be further reduced and light transmission is reduced; meanwhile, almost light can be absorbed by the black paint on the black surface, and the influences on residual character positions, caused by second time of reflection, are reduced.

Description

technical field [0001] The invention relates to the technical field of manufacturing automotive interior parts, in particular to a method for preventing light leakage from a gear panel. Background technique [0002] Due to the dimensional tolerances of the structure and process of the traditional car interior gear panel, it is impossible to achieve zero-gap contact between the electronic module and the gear panel, so that light leaks from the gap between the electronic module and the gear panel. The overall transparent structure affects other positions that do not need to be illuminated. At the same time, because the white paint at the bottom of the gear panel has a strong effect of reflecting light, the light will be reflected when it hits the white paint, and part of the light will also reach the unlit position through reflection in the gear panel. Contents of the invention [0003] In order to solve the above problems, the object of the present invention is to provide ...
