Deflection measuring device of flat-panel display substrate glass

Abstract

The invention discloses a deflection measuring device of a flat-panel display substrate glass. The deflection measuring device of the flat-panel display substrate glass comprises a rack, an air cylinder is fixed in the middle of the rack, two supporting seats which move along two guide rails are respectively arranged on the two guide rails, two steel cables which are vertical to the guide rails are arranged between the two guide rails, two ends of the two steel cables are respectively and fixedly connected with the supporting seat, two reading number scaleplates are respectively, vertically and fixedly arranged between the middle positions of the inner sides of the two guide rails. The deflection measuring device of the flat-panel display substrate glass has the advantages of being capable of reducing error of manual measure, and guaranteeing accuracy of measure. Meanwhile, the deflection measuring device of the flat-panel display substrate glass further has the advantages of being simple and secure in operation, convenient and fast to measure, thereby effectively improving working efficiency.

Description

technical field [0001] The invention relates to a measuring device, in particular to a deflection measuring device of a flat panel display substrate glass. Background technique [0002] The deflection is defined as the linear displacement of the centroid of the cross section along the direction perpendicular to the axis during bending deformation, which is called the deflection. The deflection measurement method of the traditional glass substrate is a manual measurement method. During the measurement process, the position of the support body and the glass substrate is manually placed and positioned. The measurement requires high measurement experience and operation level, and the measurement error is relatively large; Moreover, during manual measurement, the sagging speed of the glass cannot be accurately controlled, and the phenomenon of broken and broken plates is prone to occur during the measurement process, which is time-consuming and dangerous; and during manual mea...
