Tempered glass window processing method for touch screen and mobile terminal {METHOD FOR PROCESSING GLASS WINDOW OF TOUCH SCREEN AND PORTABLE TERMINAL}

The present invention relates to a method for processing a tempered glass window for a touch screen and a portable terminal, and more particularly, to a method for processing a tempered glass window for a touch screen and a portable terminal to improve productivity while reducing work time and reducing a defective rate. will be.

Generally, a glass window applied to a touch screen and a mobile terminal such as a mobile phone corresponds to an outer layer of the liquid crystal display, and prevents scratches from being generated on the liquid crystal display such as an LCD or protects it from external impact. It is equipped to take charge.

Such a glass window has a variety of appearances according to the form of the touch screen and the portable terminal, for which processing work such as cutting of the original glass is made essentially.

Looking at the processing method of the glass window applied to the conventional touch screen and the portable terminal as follows.

Referring to FIG. 1, when the original glass is put in, the original glass is inspected for scratches or other foreign matters (S1), and the original glass is cut in a state where the original glass is loaded in the cassette to have the appearance of a glass window, but the outer shell Cut out and split (S2) to have a margin of 0.5mm-2mm, and remove the outer shell of 0.5mm-2mm left on the side of the glass window divided by the cutting of the original glass by grinding using a grinding grinder (S3) Process the hole to be used for mounting the key button or the camera lens on the glass window of which the external polishing is completed (S4), chamfering the outer surface of the polished glass window and processing the external surface by polishing the inner surface (S5). It is made, including.

Then, the surface of the glass window is finished, both surface polishing (S6) and performing the post-process, such as washing step (S7) and the strengthening step (S8) by heat treatment to complete the manufacture and production of the glass window.

However, according to the glass window processing method for a touch screen and a portable terminal according to the prior art, since the original plate is cut first, the glass window is divided, and the outer shell is polished and removed, which causes a material leak and a long manufacturing process. .

In addition, there was a problem that the work time is long because there are a lot of handwork in the past, there were a lot of product defects and there was also a problem of low productivity.

The present invention has been made to solve the above-mentioned conventional problems, it is possible to greatly reduce the manufacturing process and working time, and to eliminate material leakage as well as to reduce the defective rate of the glass window manufactured Of course, the object of the present invention is to provide a method for processing a tempered glass window for a touch screen and a portable terminal to improve productivity.

The present invention is a processing method for producing a tempered glass window for a touch screen and a mobile terminal by processing the original glass,

A first step of attaching the P.V.C series films to both surfaces of the disc glass; A second step of marking an image by cutting a portion of the film through a plate cutting and a laser cutting process on the original glass to which the P.V.C series film is attached; A third step of cutting and dividing the glass window from the original glass by sand-etching the original glass and physically cutting along the marked image; A fourth step of chamfering the outer surface of the glass window divided by the sanding etching; And a fifth step of separating the film used for marking the image from the glass window.

The present invention can perform the process of image marking and dry etching using plate cutting and laser cutting, and also can be processed by an automated process, which can greatly reduce the manufacturing process and working time and eliminate material leakage compared to the conventional Not only can the defect rate of glass windows be reduced, but it can also improve productivity while reducing labor costs.

Hereinafter, the present invention will be described in detail with reference to the accompanying drawings.

As shown in Figures 2 and 3, the glass screen processing method for a touch screen and a portable terminal according to an embodiment of the present invention, when the original glass is put in checks whether there is no scratch or various foreign matter on the original (S11).

As shown in FIG. 3 (a), the film 20 is attached to both surfaces of the disc glass 10 (S12).

In this case, it is preferable that the film is to use a PVC-based film, the application of the PVC-based film in this way can easily cut the processing part when marking the image using a laser that proceeds later to facilitate the marking treatment It is intended to provide the ease of image processing for appearance.

As shown in FIG. 3 (b), the image glass 30 is drawn and marked on the disc glass 10 to which the P.V.C series film 20 is attached by using flat plate cutting and laser cutting (S13).

Here, the image refers to the external image of the glass window for mounting on the touch screen and the mobile terminal can be represented in a wide variety of forms, the film of the PVC series by irradiating the flat cutting and laser cutting machine to the film 20 side 20 is cut to mark the image 30 on the disc glass 10.

In this case, the flat plate cutting machine and the laser cutting machine cut all the same positions of both side films 20 attached to the other surface of the disc glass through light transmission as well as one surface of the disc glass 10 and both sides of the disc glass with the same image 30. Can be marked.

When the marking of the image 30 using the flat plate cutting and laser cutting machine is completed, physical cutting is performed by dry etching along the marking portion of the image formed on the disc glass 10, as shown in FIG. 3 (c). The glass window 40 is cut out from this (S14).

At this time, by the dry etching, the glass window 40 maintains its appearance, and during the dry etching, the glass window 40 may be formed on the glass window 40 together with a hole 50 for mounting a key button or a camera lens. .

Here, the dry etching means a sanding etching using the gold steel and aluminum oxide powder, it will be possible to prevent the occurrence of environmental problems and the like by utilizing such dry etching.

Chamfering the outer side surface of the glass window 40 divided by the dry etching to process the outer shape (S15).

At this time, if the hole 50 is formed on the glass window 40 during dry etching, the inner surface of the hole 50 may be polished and processed together.

Subsequently, the film separating step (S16) and the heat-reinforcing step (S17) and the washing step (S18) by peeling off and removing the film 20 attached to the glass window 40 are carried out in the glass window. The manufacturing is completed.
