Abstract
An edge grinding apparatus and method for grinding a glass substrate, with which a glass substrate can be ground by a fixed amount and the occurrence of defects can be minimized. The edge grinding apparatus includes an edge grinding unit which grinds a cut edge of a glass substrate while following the cut edge; a measuring unit which obtains positional information of the cut edge; and a control unit which receives the positional information of the cut edge from the measuring unit and controls a position of the edge grinding unit based on the positional information of the cut edge.
Claims7
An edge grinding apparatus for grinding a glass substrate, comprising:
- an edge grinding unit which grinds a cut edge of a glass substrate while following the cut edge;
- a measuring unit which measures positional information of the cut edge;
- and
- a control unit which receives the positional information of the cut edge from the measuring unit and controls a position of the edge grinding unit based on the positional information of the cut edge;
- wherein the measuring unit comprises a first measuring unit installed upstream of the edge grinding unit with respect to a path along which the glass substrate moves, the first measuring unit measuring the positional information of the cut edge of the glass substrate before being ground by the edge grinding unit,
- and the control unit controls the position of the edge grinding unit based on the positional information of the cut edge of the glass substrate before being ground by the edge grinding unit.
An edge grinding method for grinding a glass substrate comprising:
- measuring, with a measuring unit, positional information of a cut edge of a glass substrate;
- receiving, by a control unit, the positional information of the cut edge;
- controlling, with the control unit, a position of an edge grinding unit based on the positional information of the cut edge;
- and
- grinding, with the edge grinding unit, the cut edge while following the cut edge;
- wherein measuring with the measuring unit comprises measuring, with a first measuring unit installed upstream of the edge grinding unit with respect to a path along which the glass substrate moves, the positional information of the cut edge of the glass substrate before being ground by the edge grinding unit,
- and controlling with the control unit comprises controlling the position of the edge grinding unit based on the positional information of the cut edge before being ground by the edge grinding unit.
