Abstract

If a polishing surface is soaked in hydrofluoric acid or alternative solution for melting glass and then vibration is applied to the surface, a microcrack of the polishing surface is melted by the hydrofluoric acid solution and then healed to be smooth. However, the surface should not be melted, so the glass to be healed is attached to a plurality of water glass layers and then pre-pressurized and its outer part is polished and then the edge of the glass is exposed. Water glass between glasses, which is overlapped after being soaked in an organic solvent (for example, acetone) is melted to a predetermined depth to expose a corner of the glass and then glass is soaked in the hydrofluoric acid solution and then vibration is applied to the glass, and thus, the hydrofluoric acid solution, the polishing surface, and the corner rub against each other, so the exposed corner part is cut into a c- or r-shape and the microcrack part of the polishing surface is melted smoothly for healing work. Thus, as the surface is protected in a state that a plurality of water glass layers are overlapped, while the microcrack of the polishing surface is melted by the hydrofluoric acid solution after the polishing work, c-processing and healing are performed at the same time, so a defect rate is reduced and productivity is improved.

Description

[0001] The present invention relates to a laminated glass processing method and a healing method using a glass-

Glass, lcd, monitor, TV, touch screen, smart phone, tablet, camera lens, lens protective cover

Currently, it is the glass that forms the protective cover of LCD, OLED and camera lens which is the basic device for making TV, tablet, and smart phone. After cutting glass, polishing process, After polishing, the microcracks are formed on the polished surface, and microcrec grows and breaks due to various processes such as heat treatment after the heat treatment. As a method of treating the microcracks, the microcracks are healed by using a hydrofluoric acid solution. In order to protect the glass surface, a protective film must be applied to the glass surface or ink (resin) must be coated on the entire surface in order to protect the glass surface. Coated glass surface to be healed. It is very difficult to work. In order to increase the productivity, we use wax to process cnc, centering machine, etc. to overlap with several pieces of glass. Since the wax material is thin, It is becoming a source.

The microcleks on the polished surface are healed by using water glass which is an adhesive material that can dissolve in the hydrofluoric acid which can heal the processed surface in the overlapped state by replacing the adhesive which is made by stacking several layers of glass, We want to reduce badness and productivity by growing.

If the polishing surface is immersed in a solution of fluoric acid or hydrofluoric acid to dissolve the glass and gives a weak vibration, the microcrope on the polishing surface is healed smoothly by the hydrofluoric acid solution. In this case, since the surface must not be melted, the glass to be healed is dissolved in water glass Soda), pre-press the glass outside, immerse it in a hydrofluoric acid solution, and give a weak vibration, the microcore part of the processed surface melts smoothly and the healing process proceeds as the fluoric acid solution, glass-

To melt the corners more gently

Glass edge It is a method to expose the joint surface for a certain amount of time. It exposes the edge of the glass by melting the water glass which plays a role of adhesion between the overlapped glass and the glass for a certain time in water, And the edge of the glass is rubbed to expose the corner portion in the form of c or r and the microcore portion of the abrasive surface melts smoothly so that the healing operation proceeds.

It protects the surface of the glass with several layers of waterglass, dissolves the microcracks of the polished surface with the fluoric acid solution after curing, and simultaneously works the c-processing and the healing, thereby reducing the defect rate and improving the productivity.

After several layers of glass were layered with water glass, pre-pressure was applied to the glass block, followed by a cutting process known in the art, followed by polishing using a diamond wheel using a grinder, cnc, etc., When exposed to the water for a certain period of time to expose the edge of the glass, the water glass, which acts as an adhesive between the glass and the glass, is melted to a certain depth to expose the edge of the glass. Then, the glass block is put in the fluoric acid solution, In order to make the microcracks on the polished surface melt and heal while causing friction with the polished surface, water glass with glass and glass is prevented from penetrating the surface of glass to protect the glass surface, and microcrec of the polished surface or cut surface is healed The work will be a healed glass block in water After putting it, heat it. Glass adhesion surface Glass splitting, polishing surface, edge healing method that glass material which is remaining in water glass is boiled and steam is generated and the bonded glass is separated.
