A deflection measuring device for flat panel display substrate glass

Abstract

The invention discloses a device for measuring the deflection of the substrate glass of a flat-panel display. Guide rails are respectively fixedly installed on the sides, and two supporting bases movable along the guide rails are respectively installed on the two guide rails, and two steel cables perpendicular to the guide rails are arranged between the two guide rails. , the two ends of the two steel cables are respectively fixedly connected to the support seat, and a reading scale is vertically fixedly installed in the middle positions inside the two guide rails. The deflection measuring device of the flat panel display substrate glass of the present invention reduces the error of manual measurement and ensures the accuracy of the measurement. Meanwhile, the device has the characteristics of simple operation, safety, convenient measurement and effective improvement of work 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 measur...
