Abstract

The invention discloses a glass contour measuring device and a measurement method thereof. The glass contour measuring device comprises a measurement platform, an air bag and a sensing operation unit,the measuring device uses the air bag to completely fill an accommodation space, formed by curved-surface coverage glass, in the measurement platform, and changes a movement manner of the sensing operation unit to measure the deformation amount of the air bag after inflation, and thus, the glass contour of the curved-surface coverage glass is reckoned.

Description

technical field

[0001] The present invention relates to a measuring device and its measuring method, in particular to a glass profile measuring device and its measuring method. Background technique

[0002] With the gradual maturity of flexible organic light-emitting diode (Organic Light-Emitting Diode, OLED) display manufacturing technology, more and more mobile phones with curved surface (Curved) design appear on the market. The effect of the designed mobile phone is better; followed by the technical change of the cover glass factory: the edge of the curved cover glass (Cover Glass) is changed from the traditional plane (2D) to the curved design (3D), and the curved cover glass (Curved CoverGlass) The concept of the need arises.

[0003] At present, Cover Glass manufacturers need to complete the processes of computerized numerical control (CNC) cutting, edging, hot bending, and chemical strengthening of the master glass to produce CurvedCover Glass (hereinafter referred t...
