Description

[0001] The present invention relates to a glass substrate edge heat treatment apparatus,

The present invention relates to a glass substrate frame heat treatment apparatus.

In general, various apparatuses for heat-treating the rim of a glass substrate have been known.

For example, as shown in Fig. 1 and Fig. 2, a "method and apparatus for removing cracks at the cutting edge of a glass substrate" (hereinafter referred to as "apparatus") of Application No. 10-2011-0053495 is typical, The contents are as follows.

Referring to FIG. 1, a glass substrate GL cut into a predetermined shape is shown. The glass substrate GL is formed by cutting a circular hole HL and a long hole SH.

The upper surface TS of the glass substrate GL is formed by the upper outer cut corner CNb and the upper cut edge CNc of the circular hole HL and the upper cut edge CNd of the long hole SH, The lower surface (not shown) of the lower cutting edge GL comprises a lower outer cutting edge CRb and a lower cutting edge CRc of the circular hole HL and a lower cutting edge CRd of the long hole SH.

In addition, the cut surfaces connect the corresponding upper cut edges to the lower cut edges. For example, the outer cut surface OC is a surface connecting the upper outer cut corner CNb and the lower outer cut corner CRb.

As shown in an enlarged view on one side, a minute crack C is generated in the vicinity of each of the cut edges when cutting the glass substrate.

Fig. 2 shows a burner B used in an apparatus for removing a crack at a cutting edge of the glass substrate GL.

The burner B is composed of a flame radiation plate FB, a combustion gas supply cylinder GB and a burner support BS (fh). The combustion gas supply pipe GS is connected at one end to the combustion gas supply cylinder GB And a connector CT is connected to the multi-stage.

The flame radiation plate FB has a flame emission surface FBa. Since the glass substrate GL has a planar shape, the flame emission surface FBa is also formed as a flat surface. However, if the glass substrate is curved, the flame emission surface FBa is also preferably curved.

The flame radiation plate (FB) has a flame emission hole (FF) formed along the cut edge contour of the glass substrates to be processed and can be replaced according to the glass substrate to be processed.

Each flame emission hole (FF) communicates with the combustion gas supply cylinder (GB).

The outline of the lower outer edge cutting edge CRb of the lower surface of the glass substrate GL corresponds to a virtual single closed curve S1 and the lower cut edge CRc of the circular hole HL of the glass substrate GL Corresponds to a virtual single closed curve S2 and the contour of the lower cut edge CRd of the long hole SH of the glass substrate GL corresponds to a virtual single closed curve S3.

Therefore, the flame is radiated through each of the single closed curves S1, S2, and S3, and the heat treatment process of the glass substrate GL proceeds.

However, in the above-mentioned conventional heat treatment apparatus, if the glass substrate is enlarged, even if the glass substrate itself is slightly twisted, it does not coincide with the position of the flame emitting holes in the outer edge of the substrate, There was a problem.

In addition, as the number of the above-described flame emission holes increases, the parasitic discharge is generated through the plurality of flame emission holes, and the heat treatment conditions of the edges of the glass substrate are changed.
