Glass panel automatic warping degree measurement instrument

Abstract

The invention discloses a glass panel automatic warping degree measurement instrument. The glass panel automatic warping degree measurement instrument comprises a bottom seat, a high accuracy laser distance meter, a double shaft guide rail which is used to fix the high accuracy laser distance meter and moves and a fixing frame, wherein the double shaft guide rail is installed on the bottom seat and composed of a horizontal transverse guide rail and a horizontal lengthways guide rail, the high accuracy laser distance meter is installed on the fixing frame, and the fixing frame is installed on the horizontal transverse guide rail in slide mode. The glass panel automatic warping degree measurement instrument further comprises a plurality of flexible support frames and high accuracy horizontal glass used for correction, wherein the flexible support frames are arranged below sample glass, and the high accuracy horizontal glass and the sample glass are both arranged right below the high accuracy laser distance meter and used for detection. The glass panel automatic warping degree measurement instrument obtains a device measurement baseline by measuring the high accuracy horizontal glass, and due to the fact that the device baseline participates in the calculation process of warping degrees, a result error of the glass panel automatic warping degree measurement instrument is greatly reduced, and measurement accuracy is improved. Simultaneously, a nine point warping measurement technology is used, and warping values in eight directions of the sample glass is figured out through measurement results of nine points, and furthermore precision and accuracy of measurement are greatly improved.

Description

[0001] Technical field [0002] The invention relates to a glass testing device, in particular to a high-precision glass product warpage measuring device. [0003] Background technique [0004] In recent years, the rapid development of electronic products such as mobile phones and tablet computers has promoted the rapid development of the glass industry. In the production process of glass products, due to uneven heating, internal residual stress, etc., it is easy to cause the deformation of the glass surface, so that after the protective glass of the electronic product is bonded to the screen, a greater stress is generated between the two, which affects the screen Life. [0005] Traditional warpage measurement methods include: manual measurement, catheter measurement, probe measurement, etc. These methods use manual observation for measurement, and the measurement results will be affected by the operator's own judgment. Different operators will have different measurement data, whic...
