[0058] As shown in FIG. 4 , the scribe using magnetic force to control pressure according to the first embodiment of the present invention includes: a head 40 including a pressure applying magnet 46 for a permanent magnet; a movable head 50 including a permanent The pressure of the magnet receives the magnet 52, the movable head 50 is movably connected to the lower end of the head 40; and the wheel holder 56, which is mounted at the movable head 50.

[0059] Head 40 includes housing end 43 , pressure device 44 , and housing 42 . The housing end 43 is formed at the lower end of the head 40 and is connected to the movable head 50 so that the movable head 50 is movable within a certain range. The pressure device 44 has a hollow so that the pressure applying magnet 46 can be positioned. The housing 42 has a hollow to accommodate the pressure device 44 .

[0060] The movable head 50 includes a wheel holder connecting portion 54 , a pressure receiving portion shaft 53 , and a pres...

Abstract

The invention provides a scriber employing magnetic force to control pressure which can apply pressure uniformly onto a substrate in a right condition. The scriber comprises a first magnet connected with a wheel which is used for making a crack on substrate; a second magnet for generating a predefined repulsive force opposite to the first magnet; and a head part, in which the first and second magnets are movable. For the reason that the magnet is between the head part and the wheel holder, the pressure applied on wheel holder can be uniformly maintained by magnetic repulsive force, so that an effect of maintaining uniform crack depth can be obtained.

Description

[0001] Related Application Cross Reference [0002] This application claims the benefit of Korean Patent Application No. 10-2005-0133742, filed on December 29, 2005, the disclosure of which is incorporated herein by reference in its entirety. technical field [0003] The present invention relates to a scriber for controlling pressure using magnetic force, and more particularly, to such a scriber for controlling pressure using magnetic force that enables the applied pressure to be under optimum conditions uniformly on the substrate. Background technique [0004] Typically, glass substrates used in flat-panel displays such as liquid crystal displays (LCDs) are cut and processed from large-sized master sheets according to the size of the display. [0005] The process of cutting a brittle material such as a glass substrate is performed by a scribing process, in which a cutting line is formed on the surface of the glass substrate by a tool made of a diamond material (harder than...
