Problems solved by technology

[0012] That is, in the case of picking up the sheet glass and transferring it from the processing table for cutting in order to move the sheet glass after cutting to the subsequent process, sometimes the cut surface of the sheet glass in the middle is lifted and placed on the processing table. The collision and sliding between the cutting surfaces of the flat glass on the upper surface will cause scratches and cracks at each cutting surface, resulting in a decrease in the quality of the flat glass
[0013] Therefore, when transferring the cut plate glass, it is necessary to avoid the collision and sliding of the opposing cut surfaces of the plate glasses, but the actual situation is that there is no explanation about the measures for avoiding the collision and sliding.

Embodiment Construction

[0040] Below, based on the attached Figure 1a ~ Figure 1h , Figure 2a ~ Figure 2d The method of cutting and separating sheet glass according to the embodiment of the present invention will be described.

[0041] As the cutting and separating method of flat glass according to the first embodiment of the present invention, such as Figure 1a ~ Figure 1h As shown, a description will be given of the case where the plate glass G is cut into nine rectangular plate glasses G by laser cutting, and the cut plate glasses G are separated from each other, and those that cannot be used as products are discarded. part. It should be noted, Figure 1a ~ Figure 1g is a top view, Figure 1h From Figure 1a A side view viewed in the direction of arrow D shown.

[0042] Such as Figure 1a As shown, in 1st Embodiment, the sheet glass G cut|disconnected by the laser cutting method is mounted on the sheet|seat S (henceforth only referred to as the sheet|seat S) which has stretchability. As t...

Abstract

A method for cutting and separating plate glass (G), said method including a cutting step in which a laser cutting method is used to cut plate glass (G) along planned cutting lines (X, Y) and a separation step in which adjacent cut pieces of plate glass (G) are separated from each other. The cutting step is performed with the plate glass (G) laid on top of a sheet (S) that stretches, and the separation step is performed by stretching said sheet (S).

Description

technical field [0001] The present invention relates to a method for cutting and separating sheet glass. Specifically, it relates to a technique for separating each sheet glass after cutting the sheet glass by a laser cutting method. Background technique [0002] In the manufacturing process of flat glass products represented by glass substrates such as plasma displays (PDP), field emission displays (FED), and electroluminescence displays (ELD), small-area flat plates are cut from large-area flat glass glass, or to trim the edges along the edges of flat glass. As a method for realizing the above-mentioned operation, a method of cutting sheet glass is mentioned. [0003] In this case, as one of the methods of cutting sheet glass, there is a laser cutting method, and this technique is disclosed in Patent Document 1 described below, for example. [0004] Patent Document 1 discloses a technique of controlling the absorption coefficient of a laser beam of flat glass so that the...
