Abstract

The aperture size measurer consists of two parts of hardware and software, its hardware includes power source connected to photocoupling sensor, shadow mask slot, magnifying glass, photocoupling sensor, image card and industrial control computer comprising keyboard, hard disc, mouse, display, printer and software program. The measuring process includes calibration, automatic measurement and manual measurement. The present invention can measure the length size between any two points in the collected image with measurement error less than 2 mm, and the measurement results may be displayed, printed and stored.

Description

1. Technical field [0001] The invention relates to an aperture measuring device and a method for measuring the aperture size thereof, in particular to aperture and working plate size measurement in flat shadow mask manufacturing of color tubes and aperture measurement of fine items in other industries. 2. Background technology [0002] The aperture size of the shadow mask produced in the prior art has always been measured by microscope visual observation method, the reading error of such measurement is large, the accuracy is poor, and it will have a bad influence on the process production. 3. Contents of the invention [0003] The object of the present invention is to provide an aperture size measuring device which utilizes an optical element and a computer system to accurately measure the aperture size of a flat shadow mask. [0004] Another object of the present invention is to provide a pore size measurement method. [0005] The technical solution for realizing the obj...
