Problems solved by technology

[0007] However, this conventional anti-fingerprint coating method or super water-repellent coating method has a limitation in that it is difficult to coat the entire surface of a three-dimensionally shaped product
In other words, since anti-fingerprint coating or super water-repellent coating is applied using such a conventional coating method, it is difficult to form a coating with a uniform thickness on the sides, etc.
[0008] In addition, there is a limitation in that even if the surfaces of a plurality of exterior part preforms are coated by a single coating process, the coating cannot be performed uniformly in the preforms
In other words, due to the fact that the evaporated coating material does not diffuse uniformly within the deposition chamber, it results in differences in coating quality in the final product

Abstract

The invention provides a surface coating method and a device for an exterior part. The surface coating method for an exterior part includes positioning one or more exterior part preforms, which are objects to be surface-coated, within a deposition chamber capable of revolution and rotation; positioning one or more tablets containing a coating component on an evaporation device installed within an area surrounded by the revolution trace of the exterior part preforms; and depositing a coating layer to a surface of each of the exterior part preforms by evaporating the tablets while revolving and rotating the exterior part preforms. The surface coating method and device conduct the rotation and revolution of objects to be coated in while proceeding with a coating step, whereby an evaporated coating component can be uniformly diffused over the entire deposition chamber, and a uniform coating layer can be formed on the entire surface of each of the objects to be coated.

Description

technical field [0001] The present invention generally relates to an exterior part for a portable terminal, a household electric appliance, etc., and more particularly, to a surface coating method and a surface coating apparatus for an exterior part, the exterior part including forming a portable terminal Molded products of metal materials, plastic materials, or glass materials for external parts of household appliances, etc. that are often touched or operated by users. Background technique [0002] In general, since plastic injection molded products can be easily molded, they are widely used as exterior parts of products closely related to daily life, such as household goods, home appliances, and portable terminals. Exterior parts including such injection molded products are painted or coated according to the use of the related products. In particular, as the use of portable terminals such as portable media reproducers, digital diaries, tablet personal computers, and mobil...
