Abstract

The invention discloses a method for manufacturing a large-size glass grating. The laminated glass comprises a piece of ultra-white toughened glass as a substrate, a formed grating film material, a pvc glue and a non-autoclave PVB/EVA glass laminating production line. The method is simple to operate and can be used for one-step molding. The manufactured grating has high light transmittance and good uniformity. Through the mode, the invention can solve the problems of raw materials and product vacancy of the large-format glass grating in the 3D three-dimensional product.

Description

Method for manufacturing large-size glass grating

Technical Field

The invention relates to the processing of optical devices, in particular to a method for manufacturing a large-size glass grating.

Background

At present, there are various methods for obtaining stereoscopic impression, in which a parallax stereoscopic observer can directly observe with naked eyes without a special device. The method adopts a lenticular stereo grating or a parallel line grating, and the theoretical basis is that stereo feeling is formed by utilizing the refraction of the stereo grating to light and matching with binocular parallax and convergence of people. The earliest method for making stereo picture is mainly to print or enlarge several pictures of the same scene shot from different angles on paper by printing or photo developing and enlarging technology, and then to stick lenticular stereo grating sheet manually, so as to produce stereo effect. The process has the characteristics of difficult operation, low efficiency, poor quality and high rejection rate, and needs expensive special manufacturing equipment and consumables. Greatly hindering the application development of the technology.

In recent years, the rapid development of computer technologies, particularly image input, processing, and output technologies, has provided computer-generated convenience for synthesizing stereoscopic pictures. The computer-aided color stereo picture synthesizing method is provided and realized based on theoretical analysis of the stereo picture making principle based on cylindrical lens stereo grating and modern digital image processing technology. Compared with the traditional stereograph manufacturing process, the method has very obvious advantages in the aspects of economy, use flexibility and the like, and has wide application prospect.

Disclosure of Invention

The invention discloses a method for manufacturing a 360-degree 3D change image, which does not need a constant-temperature and constant-humidity film laminating chamber, does not need manual pasting all the time, is simple to operate, and has high transmittance and strong practicability of a large-size glass grating manufactured.

Glass is placed on the working table surface, the rubber roller, the universal wheel set and the optical coupler are limited, and a workpiece is transmitted to the optical coupler limiting position through the rubber roller set to stop running. The universal wheel set is lifted, and the workpiece can be moved to a proper position in any direction. And (5) paving the pvc glue and the grating film. Workpiece prelaminate heats the workpiece to temperature T1 to prevent glue shrinkage and misalignment. The film and glass were vacuum dewatered and edge sealed. And (4) heating by using an oil heating furnace. And vacuumizing by a vacuum unit, and heating and laminating. The rubber roller transmits the workpiece and is cooled by wind. And (6) blanking.
