Method for painting dressing faceplate with transparent windows

Abstract

A surface coating method for the panel with transparent window includes coating the water ink onto the position of transparent wnidow on panel, baking, coating the predefined paint on the surface of panel, baking, and stripping away the water ink layer to form a transparent window.

Description

【Technical field】 [0001] The invention relates to a coating method, in particular to a surface coating method of a panel with a transparent window. 【Background technique】 [0002] Portable electronic devices (such as notebook computers, PDAs and mobile phones, etc.) are often coated with different colors in order to meet the needs of different consumers, but in order to realize some functions, parts of the casing (such as infrared emission windows) It will be set as a transparent window. The prior art usually adopts the following three methods to achieve the above-mentioned purpose: (1) Open a through hole on the part of the preset transparent window on the housing, and set a step around the through hole, and then place a transparent sheet Glue it on the above-mentioned steps, so that a transparent window can be formed, and what’s more, the above-mentioned transparent sheet can be locked on the housing with screws. The disadvantage of this method is that the structure is too...

[0002] Portable electronic devices (such as notebook computers, PDAs and mobile phones, etc.) are often coated with different colors in order to meet the needs of different consumers, but in order to realize some functions, parts of the casing (such as infrared emission windows) It will be set as a transparent window. The prior art usually adopts the following three methods to achieve the above-mentioned purpose: (1) Open a through hole on the part of the preset transparent window on the housing, and set a step around the through hole, and then place a transparent sheet Glue it on the above-mentioned steps, so that a transparent window can be formed, and what’s more, the above-mentioned transparent sheet can be locked on the casing with screws. The disadvantage of this method is that the structure is too complicated, and it is quite inconvenient to manufacture and assemble.

(2) When coating the shell, an auxiliary component is used in advance to cover the part of the shell where the transparent window is scheduled to be set, and then the other parts of the shell are painted, and finally the auxiliary component is removed to form a transparent window. The disadvantage of this method is that additional auxiliary components and corresponding holding devices need to be made, and the auxiliary components may fall off during the coating process, causing the transparent window to be painted and resulting in product scrapping, and because the auxiliary components have a certain height, when When coating the shell, the paint particles will be blocked or bounced off by the edge of the auxiliary component, so the coating on the edge of the transparent window of the shell is too thin, resulting in color difference compared with other parts of the shell, and at the same time, the edge of the transparent window is not neat and affects Appearance

(3) Paint the entire casing first, and then use laser engraving to peel off the coating at the corresponding position of the transparent window to form a transparent window. The coating is completely peeled off and the transparent window is guaranteed to be glossy and transparent
