    Abstract: A modular production line for the production of contact lenses comprises at least three separate modules: a manufacturing module (MM), an inspection module (IM), and a packaging module (PP). The modular production line further comprises fixedly arranged transfer interfaces between the individual modules (MM, IM, PP) for transferring the lenses from a preceding module to a subsequent module. The manufacturing module (MM) comprises a plurality of manufacturing stations (300, 301, 302, 310, 320, 321, 322, 330, 331, 340, 341, 342, 350, 351, 352) which are grouped to form a plurality of individual manufacturing units (30; 31; 32; 33; 34; 35) arranged in a closed loop. Reusable male and female molds (212, 112) are transported through the manufacturing stations of the manufacturing units, and each manufacturing unit (30; 31; 32; 33; 34; 35) comprises a plurality of the manufacturing stations (300, 301, 302, 310, 320, 321, 322, 330, 331, 340, 341, 342, 350, 351, 352). A plurality of transfer robots (36) is provided, each transfer robot (36) of the plurality of transfer robots (36) being arranged at a location between two manufacturing units (30; 31; 32; 33; 34; 35) to transfer the reusable molds from one manufacturing unit to the other manufacturing unit.

    Abstract: A method of cleaning deposited material from a molding surface (10) of a mold (1) for forming ophthalmic lenses, including bringing a cleaning head (20) into contact with the molding surface (10), the rotational axis (22) of the cleaning head (20) being arranged normal to the molding surface (10), rotating (220) the cleaning head (20) around the rotational axis (22) while maintaining the contact between the cleaning head (20) and the molding surface (10), moving the cleaning head (20) to perform a precession motion (110) around a central normal (11) on the molding surface (10), while rotating (220) the cleaning head (20) around the rotational axis (22) and while maintaining the contact between the cleaning head (20) and the molding surface (10). During the precession motion (110) the rotational axis (22) includes an inclination angle (α1,α2) with the central normal (11) on the molding surface (10).

    Abstract: A manufacturing module (MM) for contact lenses comprises a plurality of manufacturing stations (300, 301, 302, 310, 320, 321, 322, 330, 331, 340, 341, 342, 350, 351, 352) arranged in a closed loop and a plurality of lens mold carriers (1, 2) which are transported through the manufacturing stations. Each lens mold carrier (1, 2) comprises a frame (10, 20) having a predetermined number of mounting sites (100, 200) arranged along the frame. Each lens mold carrier (1, 2) further comprises a predetermined number of molds (112, 212) removably mounted to the frame (10, 20) at the mounting sites (100, 200), the molds being reusable male or female molds (212, 112). Two lens mold carriers (1, 2) are assigned to each other to form a pair, so that upon mating the pair of lens mold carriers (1, 2) the male and female molds (212, 112) are mated to form mold cavities defining the shape of the lenses. The manufacturing stations comprise a mold changing station (300, 301, 302) configured to be capable of removing a mold from its mounting site (100, 200) and mounting a different mold at the said mounting site (100, 200), or configured to change the rotational position of a mold (112, 212) mounted to the frame (10, 20), or both.

    Abstract: There are described a method for applying a coating to a surface of an ophthalmic lens mold. The mold includes male and female (20) mold halves, with each of the mold halves being provided with a lens forming surface (21). The method includes applying a temporary coating to at least a portion of at least one of the male and female mold halves (20), the temporary coating being capable of reducing adhesive forces between a lens forming material and the lens forming surface (21); and drying the temporary coating applied to the portion of the lens forming surface (21). Also described is a device (1) for applying such temporary coating to the portion of the lens forming surface (21) of the ophthalmic lens mold.
