The present invention pertains to a device for machining a cut corner of a thin glass plate, and more specifically to a device for removing fine cracks formed at cut corners of a glass plate. The device for removing the cracks of the corners of a glass plate according to the present invention comprises: a burner for melting the cut corners of a glass plate; a combustion gas supply means for supplying combustion gas to the burner; and a rotary vacuum adsorption gripper for gripping the glass plate such that the glass plate approaches the burner. The burner comprises a flame throwing surface, and a plurality of flame throwing holes which are formed on the flame throwing surface and disposed such that virtual lines connecting neighboring flame throwing holes form at least one single closed loop. The rotary vacuum adsorption gripper includes a rotation shaft which is disposed in parallel to the flame throwing surface of the burner, and a vacuum adsorption arm of which one end is fixed to the rotation shaft and the other end is formed with an adsorption surface. The vacuum adsorption arm is mounted such that one surface of the glass plate faces the flame throwing surface of the burner, wherein the glass plate is adsorption-gripped at a set position when the rotation shaft rotates. The rotary vacuum adsorption gripper is more preferable than a plurality of vacuum adsorption arms to improve productivity. In addition, the adsorption surfaces of a plurality of vacuum adsorption arms are respectively vacuumed in a vacuum adsorption section and vacuum released in a vacuum release section with respect to one cycle of the rotation shaft. |
