Title
(EN) METHOD FOR MOUNTING FUNCTIONAL ELEMENTS IN A LENS
(FR) PROCÉDÉ DE MONTAGE D'ÉLÉMENTS FONCTIONNELS DANS UNE LENTILLE
Abstract
(EN)
A method for mounting functional elements (230) in a lens comprises the steps of mounting the functional elements (230) on a foil (216), applying a closed contour alignment surface of an alignment tool (225) having a central opening surrounded by the closed contour on the foil portion opposite to the mounted function elements (230), applying underpressure on the central opening to maintain the foil portion with the mounted functional elements (230) on the alignment tool (225), cutting a flap comprising the foil portion and supporting the functional elements (230) out of the foil, positioning and aligning the flap through actuator, fixing the position of the flap against the adjacent foil surface, embedding the foil (216) with the mounted functional elements (230) in a predetermined distance to the front surface of a mould (212), and casting and curing the lens with the embedded foil.

La présente invention concerne un procédé de montage d'éléments fonctionnels (230) dans une lentille qui comprend les étapes consistant à monter les éléments fonctionnels (230) sur une feuille (216), à appliquer une surface d'alignement de contour fermé d'un outil d'alignement (225) ayant une ouverture centrale entourée par le contour fermé sur la partie de feuille en regard des éléments fonctionnels montés (230), à appliquer une pression négative sur l'ouverture centrale pour maintenir la partie de feuille avec les éléments fonctionnels montés (230) sur l'outil d'alignement (225), à découper un rabat comprenant la partie de feuille et à supporter les éléments fonctionnels (230) hors de la feuille, à positionner et à aligner le rabat par l'intermédiaire d'un actionneur, à fixer la position du rabat contre la surface de feuille adjacente, à incorporer la feuille (216) avec les éléments fonctionnels montés (230) à une distance prédéfinie par rapport à la surface avant d'un moule (212), et à couler et à durcir la lentille avec la feuille incorporée.
