Problems solved by technology

However, direct plating of non-conductive film on ultra-thin glass has the problem of adhesion, and the second is the obvious drop in impact strength of ultra-thin glass due to the difference in stress between the non-conductive film and the surface of the glass.

Embodiment Construction

[0021] 1. Shape processing of ultra-thin glass:

[0022] According to the design size and shape of the screen, a CNC engraving machine is used to replace the special CNC tool with a hard drill bit and a grinding wheel coated with emery on the surface. Use the end milling function of CNC engraving machine and the simulation control system to carry out end milling on the workpiece along the designed CNC trajectory, and can simultaneously cut or / and punch holes, chamfer inside holes or edges on a single piece or multiple pieces, Will not cause any damage to the glass. The invention changes the traditional CNC cutting operation into grinding operation, which can not only be used for rough machining blank processing, but also can be used for finishing machining. Compared with the usual cutting process, the geometry of the cutting edge of the tiny emery grains on the surface of the drill bit or grinding wheel is uncertain (the negative rake angle is -60°~-85°, the edge wedge angle ...

Abstract

The present invention relates to communication equipment, and is especially cellphone window protecting screen making process. The process includes the following steps: CNC machining superthin glass to the required size and shape, toughening glass part chemically, coating transparent color insulating film to the lower surface of the glass part through low temperature electronic beam evaporation, adhering anticracking film to the lower side of the insulating film, and coating hard film to the upper surface of the glass part through magnetically controlled sputtering. The cellphone window protecting screen has high impact strength, high scratch resistance and high safety, and the process has low production cost, high production efficiency and high product quality.

Description

Technical field: [0001] The invention relates to communication equipment, in particular to a method for preparing a mobile phone window protection screen. Background technique: [0002] The liquid crystal display (LCD) on a mobile phone is usually composed of two pieces of ultra-thin ITO (indium tin oxide) glass with a thickness of 0.4-0.55mm. If the LCD is directly exposed, it will be easily damaged during use. Therefore, the LCD on the existing mobile phone All are equipped with window protection screens that not only protect the LCD, but also play the role of beautiful decoration. There are two ways to make the existing window protection screen: 1. The way of mold opening and injection molding, also known as IMD technology (in-mold inlay technology), the advantage of this method is that it is easy to realize the curved surface shape, and the disadvantage is that the cost is high and the surface is scratch-resistant Poor ability; 2. Flat CNC cutting method, the main mater...
