Description

Technical Field [0001] The present invention relates to a production method and a cutting system for a cutting product,

The present invention relates to a production method of a cut product and a cutting system.

In general, a product on glass or film (or sheet) is produced in the form of a fabric having a size larger than the size of the product to be actually used. For example, tempered glass, a touch sensor, a polarizing plate, or a phase difference plate used in a portable terminal or a display device is used. For example, in the case of a touch sensor of a predetermined size, a glass substrate (fabric) having a similar length and width is cut into a plurality of unit products.

Generally, a method of cutting a fabric so that a plurality of unit products can be obtained simultaneously by a small number of cutting processes is widely used. For example, a cut frame equipped with a plurality of cutters can be used, and the yield of a cut unit product varies depending on how the cut is performed. Lower cutting efficiency increases scrap, or waste, that is discarded after cutting, which ultimately leads to increased product manufacturing costs.

On the other hand, a slitting cut that is long in one direction can be used. However, depending on the characteristics of the fabric, such a slitting cut may be advantageous in terms of reducing the number of cutting processes, but it may be disadvantageous in terms of increasing the area yield of the fabric. Therefore, a cutting method capable of improving the area yield is required.

On the other hand, in this document, "cutting" can be used to mean one or more selected from "slitting cutting" and "free cutting ". In this document, the term "slitting cutting" means that the raw fabric 10 is cut in a length direction (Y) to cut into a band-shaped semi-finished product. (Y) direction and width (X) direction, respectively, and cut into a unit product.

In addition, the slitting and free cutting can be distinguished according to the arrangement of the unit products on the virtual cut line 20. [ In the case of the slitting cutting, the unit products should be arranged side by side along the length (Y) direction of the raw fabric so that they can be cut long in the direction of the length (Y) of the raw fabric 10. On the other hand, in the case of free cutting, the arrangement of the unit products on the virtual cut-out is more free than that of the slitting cut.

In this document, a single cut means to cut the fabric (10) into a single unit product, and a composite cut means to cut the fabric (10) into two or more unit products. Here, the type of the unit product may be classified based on the size of the unit product (for example, 7 inches or 8 inches).

In the present invention, the cutting method is not particularly limited. The cutting may be performed, for example, through a metal knife, a jet water knife and / or a light source, and the light source may be a laser beam or the like.
