Wherein, can adjust the height of tensioning portion 4 through the vertical slide on the slide support 401 to control laminating structure 1's thickness, appear laminating compression roller 5 when avoiding laminating and laminate the base member 6 laminating and appear laminating badly with waiting to laminate the regional first that has not pressed.
Through the technical scheme, the invention realizes the lamination of the ultrathin glass on the small-curvature curved surface in a simple structure and an economic mode, and effectively reduces the research and development cost.
Specifically, through the mode of laminating and rolling simultaneously, the self-adaptive lamination of ultrathin glass to the curved surface is realized, the breakage and the bubble that appear of ultrathin glass when laminating are effectively stopped, and the production quality is improved.
Moreover, based on the elastic characteristics of the ultrathin glass, the self-adaptive fitting of the ultrathin glass to the curved surface is realized, the curvature of the fitted curved surface is not required to be changed for many times, and the debugging efficiency in the research and development stage is improved.
