MEASURING SYSTEM OF PANEL FOR CATHODE RAY TUBE

摘要

PURPOSE: A measuring system of a panel for a cathode ray tube is provided to perform measurement of a panel without collecting a sample to judge the pass of the measurement result rapidly,to improve the accuracy of the measurement. CONSTITUTION: A centering apparatus(100) sets a center of a panel on a table by rolling from all directions, and the panel is moved to a measuring position of a first and a second measuring apparatus(300,500) by a sending apparatus(200). The first measuring apparatus detects the dimension of the panel by performing a three dimensional measurement by moving a probe up and down and rotating the probe. The second measuring apparatus measures the shape and the roughness of the panel before and after the polishing by the driving of a first and a second measuring unit, and a series of the measuring processes are controlled by a computer.
