  • Patent number: 8342909
    Abstract: A device (1) for machining an ophthalmic lens includes a support for the ophthalmic lens and for driving it in rotation about a blocking axis (A1), a machining module (35) that can be swiveled relative to the support and driving the lens in rotation and that is suitable for pivoting about a swivel axis that is not parallel to the blocking axis of the lens, and at least one drill tool mounted to rotate on the machining module about a first axis of rotation. The machining device includes at least one other machining tool mounted to rotate on the machining module about another axis of rotation that is distinct from the first axis of rotation and that is stationary relative to the first axis of rotation.

  • Patent number: 7846009
    Abstract: The method includes: automatic measurement of the marking characteristics of the lens in a measurement position in order to produce a marking reference of the ophthalmic lens; transfer of the lens in a second transfer movement from the measurement position to an intermediate position which is distinct from the measurement position; transfer of the lens in a third transfer movement from the intermediate position to a trimming position which is distinct from the intermediate position; locking of the ophthalmic lens on trimming elements (6); trimming the lens. The third transfer is carried out by third transfer elements that make up a sub-unit which is distinct and independent from other units or includes elements carrying out the second transfer, and trimming elements, wherein full blocking of the lens on the trimming elements is only completed after the third transfer.

  • Patent number: 7803035
    Abstract: A method of working the periphery of an ophthalmic lens (L), the periphery of the lens possessing an edge face (C) and the method including edging the edge face of the lens by machining with a first grindwheel (31) mounted to rotate about an axis of rotation (A4). According to the invention, during the edging, in addition to being free to rotate about the axis of rotation, the first grindwheel possesses two degrees of freedom to move in tilting about two distinct pivot directions that are substantially transverse to its axis of rotation.

  • Patent number: 7766723
    Abstract: A device includes a measurement element for automatically measuring optical locating or identification characteristics of an ophthalmic lens, a cutting-out element for cutting out an ophthalmic lens and including an element for lens clamping, and a receiver/transfer element that receives an ophthalmic lens and transfers it in at least three transfers between at least four distinct positions, a first between a loading or unloading position for the lens and a measurement position in which the ophthalmic lens is presented aligned with the measurement element, a second transfer between the measurement position and an intermediate position, and a third transfer between the intermediate position and a cutting-out position, presenting the lens for being clamped by the clamping element of the cutting-out element. The transfer element includes a second transfer element arranged to receive a plurality of ophthalmic lenses simultaneously and to perform the second transfers of the ophthalmic lenses in turn.

  • Patent number: 7661819
    Abstract: A method includes the following steps: a step of automatically measuring centering characteristics of the lens; a step of blocking the lens on a cutting-out element; a step of cutting out the lens; and a plurality of steps of acquiring axial coordinates of acquired points of a face of the lens, including a first acquisition of axial coordinates of the lens prior to blocking the lens on the cutting-out element, and a second step of acquisition by feeling that is subsequent to the blocking step.

  • Publication number: 20080007690
    Abstract: The method includes steps of: automatically measuring locating or identification characteristics of the lens in a measurement position, to provide a locating or identification reference frame of the ophthalmic lens; transferring the ophthalmic lens in a second transfer from its measurement position to a distinct intermediate position; transferring the ophthalmic lens in a third transfer from its intermediate position to a cutting-out position distinct from the intermediate position and the measurement position; locking the ophthalmic lens on the cutting-out element; and cutting out the lens with the cutting-out element, starting from its cutting-out position.
