Embodiment Construction

[0019] A rapid measurement method for 3D curved glass, using an image system to identify the posture and position of a 3D curved glass test piece, and using a non-contact displacement sensor to scan and measure the surface of the test piece.

[0020] The specific method is as follows: import the 3D curved glass design model into the measurement software in advance, and then design a reasonable measurement path according to the model, and then place the glass to be measured on the corresponding fixture for positioning, and obtain the target surface through the image positioning system above the fixture. Measure the position and attitude of the glass in the XY direction for positioning in the XY direction. The non-contact displacement sensor is installed on a rotary table that can rotate relative to the B axis, where the B axis is arranged parallel to the X or Y axis. The rotary axis scans the entire surface of the measured object through the non-contact displacement sensor accor...

Abstract

The invention provides a rapid measurement method for 3D curved surface glass, is a universal and multi-functional measurement method capable of measuring the maximum-90-DEG-folding 3D curved surface glass and adapts to large batch production and rapid contour measurement demands of the 3D curved surface glass. The method is advantaged in that an image system is utilized to identify attitude and the position of a detected member of the 3D curved surface glass, and a non-contact displacement sensor is utilized to carry out scanning measurement on a surface of the detected member.

Description

technical field [0001] The invention relates to the technical field of glass measurement, in particular to a rapid measurement method for 3D curved glass. Background technique [0002] 3D curved glass is the current development trend of smartphones, and the market demand is increasing day by day. Curved surface profile, glass thickness, and flatness are important precision indicators of curved glass, which require key control during the production process. For the measurement of curved glass, the current main method is to use a three-coordinate measuring machine, which has low measurement efficiency and can only be used for random inspection, which does not meet the full inspection requirements of mass production of curved glass. Contents of the invention [0003] In view of the above problems, the present invention provides a rapid measurement method for 3D curved glass, which provides a general-purpose, multifunctional 3D curved glass measurement method with a maximum m...
