Abstract

A brittle material breaking apparatus using a lifting mechanism to lift/lower a carrier wherein the lifting mechanism is controlled to lift the carrier for holding the brittle material for breaking, and then to lower the carrier from the brittle material to a distance for enabling the brittle material to be shifted to a next scribe line for further breaking, preventing the occurrence of friction between the brittle material and the carrier and the production of static electricity and micro particles and, improving the breaking quality. The brittle material breaking apparatus further includes a stroke fine adjustment mechanism adapted to adjust the stroke of the breaking-cutter relative to the brittle material.
