Description

technical field [0001] The invention relates to the field of non-contact automatic detection, in particular to a 3D curved glass detection mechanism. Background technique [0002] The glass cover plates used on the displays of smart terminal products in the existing market can be divided into: 2D glass, 2.5D glass and 3D curved glass. Among them, 2D glass is ordinary pure flat glass without any curved design; 2.5D glass is The middle is a flat design, and the edge adopts a curved design; the 3D curved glass can be designed as a curved arc in the middle and the edge. 3D curved glass is mainly bent by a hot bending machine, which can achieve a higher bending arc. Some physical properties of 3D curved glass are obviously better than 2D and 2.5D glass. 3D curved glass has the advantages of being light and thin, transparent and clean, anti-fingerprint, anti-glare, hard, scratch-resistant, and good weather resistance. Better display and touch experience. [0003] The difficulty...

Problems solved by technology

[0003] The difficulty of measuring the size of 3D curved glass lies in the lack of effective imaging methods. Due to the great change in the optical properties of the glass surface caused by 3D curved glass, the problem is the classic aurora triangulation of 3D objects, the most commonly used industrial precision measurement method. Completely failed, the main reason is that because of the high light transmittance of the glass, the laser projected on the surface of the glass does not produce a high-brightness contour line that can be observed on the surface of other materials, so that the traditional industrial high The precision 3D camera directly measures the three-dimensional shape of the glass. The only way to measure it is to spray the opaque coating on the glass in advance, but the scraping of the opaque coating after spraying will cause damage to the surface quality of the glass, which is not for the existing technology. Allowed, the existing detection mechanism has poor adaptability, especially for 3D curved glass with various curved surface characteristics. In view of this, it is necessary to develop a 3D curved glass detection mechanism to solve the above problems
