Abstract
The invention relates to a process for manufacturing a vacuum insulated glazing wherein the glazing is assembled in a single stage by supplying glass panes, metallic spacers and corner and frame metallic seal elements which are brazed onto adhesion layers previously deposited onto the edge region areas of the glass panes.
Claims17
A process for manufacturing a vacuum insulating glazing, the process comprising, in the following order:
- a) first, depositing an adhesion layer onto a peripheral zone on one side of each of at least two glass panes;
- b) second, supplying the glass panes separated with a set of metallic spacers in a stack alignment as a pane stack;
- c) third, assembling the glazing by:
- c1) supplying corner metallic seal elements at each corner of the pane stack onto the adhesion layers of each glass pane,
- c2) supplying multiple frame metallic seal elements on edges of the glass panes between the corner metallic seal elements, and
- c3) simultaneously brazing the corner and frame metallic seal elements onto the adhesion layers, thereby obtaining a finished glazing of each glass pane;
- and
- d) fourth, unloading the finished glazing,
- wherein
- the glazing comprises the at least two glass panes, the set of metallic spacers located in a void space between the glass panes, and a peripheral seal ensuring a vacuum tightness between the glass panes,
- the multiple frame metallic seal elements are supplied so that each frame metallic seal element overlaps an adjacent frame or corner metallic seal element for a distance no greater than 3.5 mm, and
- each frame metallic seal element overlaps further the adjacent frame or corner metallic seal element by free dilatation during the brazing for forming the peripheral seal.
