Abstract

Disclosed is a device for cutting a substrate, wherein the brittle substrates are transported by the conveyer belt. The device comprises: a scriber for the lineation operation on the substrate; a conveyer belt for conveying the substrate to the scriber; and a reference locating device for supporting one end of the scriber on a prescribed reference position which is located between the scriber and the conveyer belt. Therefore, when using device, the cutting precision, the processing quality are enhanced and the cutting consistency is stably maintained.

Description

[0001] Cross References to Related Applications [0002] This application claims priority from Korean Patent Application No. 10-2005-0133560 filed on December 29, 2005, the entire contents of which are hereby incorporated by reference. technical field [0003] The present invention relates to an apparatus for cutting a substrate, and more particularly, to an apparatus for cutting a substrate in which a brittle substrate is conveyed by a conveyor belt. Background technique [0004] Generally, glass substrates are used for liquid crystal displays (LCDs) or organic light emitting devices (OLEDs), which are used as flat panel displays. [0005] When a glass substrate is used for the above device, it needs to be cut to fit the device. Devices with the function of cutting glass substrates are generally called scribers. [0006] A scriber performs a scribing process at a predetermined position of the glass substrate to be cut, and a breaker performs a cutting process along a slit...
