Breaking apparatus for glass substrate

A breaking apparatus for cutting a glass substrate disposed on a processing table along a scribing line, comprising:

• a breaking bar connected to a linear driver to be lifted or lowered and extending in one direction and having a predetermined width, the breaking bar having a plurality of linear bush coupling holes and a plurality of buffer cylinder coupling holes alternately arranged at regular intervals in the one direction;
• a plurality of linear bushes mounted on the plurality of linear bush coupling holes, each of the plurality of linear bushes including an outer barrel and a shaft linearly slidable inside the outer barrel;
• a plurality of buffer cylinders mounted on the plurality of buffer cylinder coupling holes, each of the plurality of buffer cylinders including a hollow cylinder body generating pressure therein, a piston received in the cylinder body, and a piston rod connected to the piston;
• and
• a breaking tip extending in the one direction and having a bar shape with a predetermined width, the breaking tip being disposed beneath the breaking bar and being connected to the piston rods of the buffer cylinders and the shafts of the linear bushes to be brought into contact with a glass substrate and to apply impact load to the glass substrate when the breaking bar is lowered.
