Problems solved by technology

Especially for the surface treatment of the display panels of electronic products such as mobile phones and tablet computers. At present, the processing of the chamfering of the display panel usually adopts the PCD tool in the CNC machining to cut the chamfering and then polish, sweep and polish. Processing to improve the surface light height of the product, the process is too complicated, do not use production operations, such as the corner processing method disclosed in the Chinese patent (publication number: CN102350661A), take a number of single sheets of glass to laminate, and each adjacent two single sheets There is a spacer layer between the glasses, and the spacer layer has the function of bonding the glass on both sides to form a laminated rectangular block glass; a protective layer is provided on the upper surface and the lower surface of the rectangular block glass; for the above block glass According to the thickness of the single glass and the spacer layer, set a special CNC tool that can process the corners of each single glass in the stacked rectangular block glass at the same time; use the special CNC tool to pass through the CNC Processing technology Corner grinding of each individual pane in the laminated rectangular glass block described above

Embodiment 1

[0017] This embodiment mainly processes the arc-shaped chamfering method of the acrylic glass panel, and the specific operation method is as follows:

[0018] According to the size of the display panel of the mobile phone product, a 0.8mm thick acrylic glass is selected for rough processing of the display panel to form a rectangular single-piece acrylic glass. Of course, the rectangular single-piece acrylic glass here can also be purchased directly from the market. Then, the above-mentioned several single pieces of acrylic glass are laminated to form a rectangular block glass, generally 8 single pieces of acrylic glass are selected for lamination, and then the rectangular block glass is placed on an ordinary jig for clamping and then fixed. ; It is better to have a paraffin layer between two adjacent single pieces of acrylic glass for bonding, so as to improve the relative fixity between each single piece of acrylic glass. After immersing in the molten paraffin liquid for 1 mi...

Embodiment 2

[0022] The basic method of this embodiment is the same as that of Embodiment 1, and will not be repeated here. The main difference is that nano-nanographite phase titanium nitride layers are deposited on both sides of the single crystal diamond blade. Vacuum sputtering coating method or other deposition methods can be used, which can improve the relative sliding between the two sides of the blade and the plexiglass, reduce the phenomenon of sticking or make the cut plexiglass waste powder stick to the surface of the blade and cause Affect the flatness of the cutting, so as to achieve more effective improvement of the bright edge and high gloss effect of the chamfer, so that the surface roughness of the acrylic glass chamfer can reach Ra within 0.02μm, and the surface gloss value is above 190. Preferably, the thickness of the nanoscale graphite phase titanium nitride layer is between 2nm and 5nm, most preferably 3nm, which will not affect the cutting sharpness of the blade and e...

Abstract

The invention relates to a machining method for highlight chamfering of a mobile phone window organic glass panel, and belongs to the technical field of glass chamfering machining. To solve the existing problem that polishing is needed after chamfering, the machining method for highlight chamfering of the mobile phone window organic glass panel is provided. The method comprises the steps that a plurality of single pieces of organic glass are laminated to form rectangular blocky glass, and the rectangular blocky glass is fixed; a tool with a monocrystal diamond blade in a CNC machining machine tool is used for conducting chamfering cutting on the rectangular blocky glass, the monocrystal diamond blade is formed by machining monocrystal diamond raw materials with the grain size smaller than or equal to 4 mm, and after cutting, each single piece of organic glass has a corresponding chamfer, and the mobile phone window organic glass panel obtained after machining and chamfering is obtained. According to the machining method, polishing does not need to be conducted after chamfering, operation procedures are simplified, the formed chamfers have the effects of highlight and a good bright border effect, and good surface roughness and glossiness effects are achieved.

Description

technical field [0001] The invention relates to a processing method for high-gloss chamfering of organic glass panels of mobile phone windows, and belongs to the technical field of glass chamfering processing. Background technique [0002] In recent years, with the development of electronic products, people's pursuit of the aesthetic requirements of products has also been continuously improved. Especially for the surface treatment of the display panels of electronic products such as mobile phones and tablet computers. At present, the processing of the chamfering of the display panel usually adopts the PCD tool in the CNC machining to cut the chamfering and then polish, sweep and polish. Processing to improve the surface light height of the product, the process is too complicated, do not use production operations, such as the corner processing method disclosed in the Chinese patent (publication number: CN102350661A), take a number of single sheets of glass to laminate, and ea...
