Embodiment Construction

[0055] Those skilled in the art understand that the elements in the drawings are illustrated for simplification and clarity, and therefore are not necessarily drawn to scale. For example, the size of some elements in the figures may be exaggerated relative to other elements to help improve the understanding of the embodiments of the present invention.

[0056] The words "upper" or "above" or "bottom" or "below" refer to the position of the optical lens relative to the optical lens when the optical lens is arranged so that the edge of the optical lens to be processed is substantially in the horizontal plane.

[0057] The position is purely a conventional position, and the optical lens can be processed in a non-horizontal position.

[0058] As shown in FIG. 1, the optical lens 100 is fastened to the holder 200 due to the fixing tool 300. The edge of the optical lens 100 is substantially located in a horizontal plane.

[0059] The upper surface 110 of the optical lens 100 is a surface t...

Abstract

A method of locking and / or unlocking an optical lens (100) onto a thermally conductive holder (200) including an upper mounting surface (210), comprising the following steps: a) on the upper mounting surface (210) of the holder providing a first layer consisting of an adhesive tape (330); b) providing a second layer consisting of a layer (310) comprising a thermoplastic material on said adhesive tape (330); c) providing a third layer to the optical lens (100) layer, the third layer consists of an adhesive tape (320) arranged on the bottom surface of the optical lens (120); d) when the thermoplastic material softens or melts, the optical lens (100) with the third layer (320) is placed on on a second layer (310) consisting of a layer containing thermoplastic material. The method of unlocking the optical lens (100) is by heating the holder (200).

Description

Technical field [0001] The invention relates to a method and device for locking and unlocking a lens. The device is used for adhering an optical lens to a lens locking device used with processing, grinding and processing equipment when preparing optical or ophthalmic lenses. Background technique [0002] The manufacturing process of preparing optical or ophthalmic lenses usually starts with unprocessed or semi-finished glass or plastic lens blanks. A typical semi-finished lens blank has a polished front surface and an unprocessed back surface. By grinding away the material from the back of the lens blank, the required corrective prescription requirements are generated. Subsequently, the surface that has been given the corrective prescription requirements is polished, and the peripheral edge of the lens blank after this treatment has the final desired contour, thereby forming a trimmed optical or ophthalmic lens. According to other processing methods, the processed ophthalmic le...
