Problems solved by technology

[0022] However, when the required processing accuracy becomes stricter, it is difficult to obtain the edge. Ultimately, it is necessary to measure the processing dimensions of all workpieces after processing, and change the correction value at any time as needed. In the chamfering device of the existing structure have to reduce productivity

Abstract

The invention provides a chamfering device of a hard fragile plate, which is used for processing a glass base plate used for a display panel and edges of other hard fragile plates. The chamfering device can measure the processing dimensions of all processed workpieces completely without or hardly increasing production beats, thereby being capable of realizing higher processing accuracy without reducing the processing accuracy. In the chamfering device comprises upstream side upper video cameras, a downstream side upper video camera and a downstream side lower camera, wherein the upstream side upper video cameras for observing the upper surfaces of the two side edge parts of workpieces are configured at both sides of the width direction of a work table, which are opposite to the upstream side of the feed direction of a tool; the downstream side upper video camera for observing the upper surfaces of the two side edge parts of the workpieces is arranged at the downstream side of the feed direction of the work table of the tool; and the downstream side lower camera for observing the lower surfaces of the two side edge parts of the workpieces is arranged at the downstream side. By means of the chamfering device, chamfering processing is carried out when the work table is in feed motion, and the chamfering dimension is measured by utilizing the downstream side cameras after the chamfering processing is carried out.

Description

technical field [0001] The present invention relates to a chamfering device for processing the edges of rectangular glass substrates and other hard and brittle plates used in display panels and the like. In particular, the present invention relates to the above-mentioned device capable of measuring processing dimensions in order to accurately set the angle of a table on which a hard and brittle plate is placed and the position of a processing tool. Background technique [0002] The chamfering device of the glass substrate (hereinafter referred to as "substrate" or "workpiece") uses a tool (generally a grinding wheel) to chamfer and Device for rounding. Generally, such as Figure 8 As shown, this chamfering device has a workbench 2 that absorbs a substrate 1 by negative pressure, and tools 3 arranged on both sides of the workbench. The table 2 can be rotated 90 degrees around a vertical axis by a rotation device not shown. The table 2 and the tool 3 are relatively movable ...
