Method for Producing Functional Laminated Glasses, Method for Arranging Glass Elements for Functional Laminated Glasses, and Arrangement of Glass Elements for Functional Laminated Glasses

Simple SummaryContent extracted from patent full text and abstract with AI.

This patent describes a method for manufacturing laminated glass units that can contain sensitive electronic or functional components (such as display screens, sensors, or photovoltaic elements) between the glass layers. The key innovation is the ability to precisely and individually control the temperature during the vacuum lamination process in different areas of the glass. This allows for lower temperatures around heat-sensitive areas where functional elements are embedded, while still applying higher temperatures at the glass edges or where robust adhesion is needed. Specialized cooling and heating elements are used to create this controlled, inhomogeneous temperature distribution.

Patent Abstract

The object of the invention is to provide a method for producing functional laminated glass units, a method for arranging glass elements for functional laminated glass units and an arrangement of glass elements for functional laminated glass units with which an area-specifically individual or inhomogeneous thermal treatment is made possible, so that even thermally sensitive functional elements in particular can be laminated into the laminated glass for a functional laminated glass unit. It is also intended to achieve an arrangement and combination of the components suitable for this. A method for producing functional laminated glass units from an arrangement of glass elements (12), wherein at least one lower laminating layer (2) is placed on a lower glass element (1) as a base glass element (1), in that at least one functional element (3) is arranged on the lower laminating layer (2) at a distance from the edge of the pane (7), in that at least one upper laminated layer (4) is placed onto the at least one functional element (3) and subsequently an upper glass element (5) is placed on as a top glass element (5), and in that subsequently a vacuum lamination of the arrangement of glass elements (12) is performed, wherein in the vacuum lamination an inhomogeneous temperature zone is produced, wherein, at least in the region of the at least one functional element (3, 13), the arrangement of glass elements (12) is brought to at least a first laminating temperature and in that, at least at the edge of the pane (7) or in the region (11) away from the at least one functional element (3), the arrangement of glass elements (12) is brought to at least a second laminating temperature, wherein the first laminating temperature is lower than the second laminating temperature.
