Title:
AUTOMATED PRODUCTION OF CONCENTRATOR LENS PANELS
Document Type and Number:
WIPO Patent Application WO/2013/135222
Kind Code:
A8
Abstract:
The present invention lies in the field of the industrial manufacturing of cast parts and relates to an apparatus and method for the automated production of parts of this type having very fine surface structures, particularly concentrator lens panels, which contain at least one, preferably annular, stepped region as per Fresnel lenses. Handling during the production of the lens panels is difficult, inter alia, because after the curing operation, on account of relatively large adhesion forces or cohesion forces, the mould is removable in a precisely reproducible manner from the product or from the system only with difficulty. It is the object of the present invention to provide a method and an apparatus for the automated production of concentrator lens panels. This is achieved in that a die containing an upper plate (8) and a lower plate (1) initially holds the mould (6) in a precisely defined manner on the upper plate, and the deformable material mass (3) lying on a glass or plastics plate (2) rests in a precisely positioned manner on the lower plate, and then the upper and lower plates are moved together leaving an intermediate space which is evacuated, and the entire sandwich packet is then joined together, kept in a pressed manner and heated until the material is firm. Specially designed securing means (13) then ensure that the sandwich packet can be undone in a reproducible manner and the mould (6) can be separated from the product (9) in a defined manner.
