Vacuum imprinting apparatus, vacuum press-bonding apparatus, and manufacturing method for laminated optical device

Abstract

The invention discloses a vacuum imprinting apparatus, a vacuum press-bonding apparatus, and a manufacturing method for laminated optical device. The vacuum imprinting apparatus and vacuum press-bonding apparatus respectively includes a vacuum chamber, a lower stage, an upper stage, and a solidifying device. The upper stage is opposite to the lower stage to be disposed in the vacuum chamber and can move toward the lower stage to perform imprinting or flatly spreading. The solidifying device is used for solidify an optical gel layer into an optical layer. The manufacturing method forms optical layers on a substrate by the vacuum imprinting apparatus and vacuum press-bonding apparatus respectively, further to form the laminated optical device. Thereby, the invention uses machines and tools to form the optical gel layers under a vacuum environment, so as to reduce bubble phenomena in the laminated structure formed by the optical layers after solidified.

Description

technical field [0001] The invention relates to a method for manufacturing a layered optical element and an embossing device and a laminating device thereof, in particular to a method for manufacturing a layered optical element using a vacuum process and a vacuum embossing device and a vacuum laminating device used therefor. device. Background technique [0002] The layered optical element in the prior art is manufactured by forming multi-layer optical layers on a substrate, and the multi-layer optical layers are sequentially cured by optical glue, wherein patterns can be printed on the optical layer by using a template as required. In the process of the prior art, the layered optical element is sequentially fabricated and formed in an atmospheric environment through processes such as coating, rolling, and curing. In the rolling process, the operator needs to align the template or protective film with the optical adhesive layer, and then use the rolling wheel to roll, which...

AI Technical Summary

Problems solved by technology

In the rolling process, the operator needs to align the template or protective film with the optical adhesive layer, and then use the rolling wheel to roll, which will easily lead to insufficient lamination accuracy, and easy to introduce air bubbles during lamination and rolling , Rolling is not easy to control the lamination gap, and the machine needs to be moved before curing, which may cause variation in the thickness of the optical adhesive layer

In addition, in the process of forming the optical layer using the rolling process using a template, the template still needs to be manually demoulded after the optical adhesive layer is cured. However, due to the large uncertainties in the manual demoulding operation, it is easy to produce problem of instability
