Embodiment Construction

[0050] Hereinafter, the preferred form of the processing method of the glass substrate which concerns on embodiment of this invention, and its apparatus is demonstrated in detail based on drawing.

[0051] figure 1 It is a process explanatory drawing which shows the cutting and breaking process and chamfering process for demonstrating the glass substrate G which concerns on embodiment. in addition, figure 2 It is a flowchart showing the flow of the glass substrate in the cutting and breaking step and the chamfering step.

[0052] As shown in these figures, the glass ribbon 1 formed into a ribbon by a glass ribbon forming device such as a float furnace is processed with a cutting knife 2 of a cutting machine in a direction perpendicular to the longitudinal direction 3 (step S1). Thereafter, the glass ribbon 1 is transported to the breaking machine by the transfer machine 4, and the part of the tangent line 3 is lifted up by the lifting member 5 of the breaking machine, so as ...

Abstract

The invention provides a processing method for glass substrates and a device therefor, wherein the chamfer processing of the glass substrate is performed without the positioning thereof to improve the production efficiency of the glass substrate.When a glass substrate (G) is placed on a workbench (12), the glass substrate (G) is absorbed to be fixed to the workbench (12) by the attracting action of the workbench (12) instead of being positioned.Then the position information of the end faces (G1, G2, G3) of the glass substrate (G) is obtained by a laser displacement meter (14-22).The processing start position and the processing end position is calculated by a CPU (28) in consideration of the position information and the desired grinding allowance.Motion mechanisms (34, 40) are controlled by a motion controller (32) based on the position information of the calculated processing start position and the end position, so that the chamfer grinding wheels (24,26) are in a linear movement from the processing start position to the processing end position.

Description

technical field [0001] The invention relates to a processing method and device for a glass substrate. Background technique [0002] The glass substrate for FPD (Flat Panel Display: Flat Panel Display) such as a liquid crystal display and a plasma display is manufactured by the method shown below. For example, the glass ribbon formed into a ribbon by a glass ribbon forming device such as a float furnace is cut and broken into a glass substrate of a predetermined rectangular size in the cutting and breaking process, and the end surface of the glass substrate is chamfered in the chamfering process. Processing, thereby making a glass substrate having the external dimensions as a product. And this glass substrate is conveyed to the surface grinding process through the cleaning process and the inspection process arrange|positioned in the back stage of a chamfering process, and the glass substrate of the product thickness is made here. These steps are often performed on one produ...
