Abstract:
A production line (PL) for the production of ophthalmic lenses (7) comprises
a manufacturing module (MM),
an inspection module (IM), and
a packaging module (PP) in which the lenses identified by the inspection module (IM) as being acceptable are packed into primary packages.
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). At least one of these manufacturing stations (310; 320, 321, 322, 330, 331) is configured to apply a lens identification code (70, 71, 72) to the respective lens. The lens identification code (70, 71, 72) includes information indicative of the type of the respective lens.
Either the inspection module (IM) or the packaging module (PP) includes a lens detection station (502, 604) configured to read the lens identification code (70, 71, 72) applied to the respective lens and to detect the type of the lens from the lens identification code (70, 71, 72) read from the respective lens in order to determine whether the type of lens detected actually is the type of lens which is expected to be detected by the lens detection station (502, 604) at that time.
