Measuring assembly for measuring a spectacle frame

摘要

A measuring assembly for measuring an inside of a lens frame of a spectacle frame, said lens frame at least partially delimiting an inscribed surface area F that corresponds to a lens shape, comprising a holding device for mounting the spectacle frame, at least one light source for generating a light beam to be projected on a region of the lens frame to be evaluated, and at least one sensor that can be coupled to an evaluation unit for detecting the reflected light beam, wherein the holding device can be rotated about a rotational axis r and moved in the direction of a movement axis x, and the movement axis x comprises at least one movement component in a direction perpendicular to the rotational axis r. The holding device is used to fix the spectacle frame by spectacle frame bows, wherein at least one free space is provided in the region of the holding device, said free space being used to receive the spectacle frame bows of a spectacle frame to be held which are not folded in or cannot be folded in.

1. A measuring assembly for optically measuring an inside of a lens frame of a spectacle frame, said lens frame at least partially delimiting an inscribed surface area F that corresponds to a lens shape, comprising a holding device for mounting the spectacle frame, at least one light source for generating a light beam to be projected on a region of the lens frame to be evaluated, and at least one sensor that can be coupled with an evaluation unit for detecting the reflected light beam, wherein the holding device and the light source can be rotated relative to one another about a rotational axis r and moved in the direction of a movement axis x, and the movement axis x comprises at least one movement component in a direction perpendicular to the rotational axis r,
wherein the holding device comprises at least two clamping element for fixating the lens frame, said clamping elements being movable in a direction of a movement axis y comprising a movement component at right angles to the movement axis x and comprising a movement component at right angle to the rotational axis r, and said clamping elements being pretensionable against the spectacle frame.
