Measuring device with automatic picking and placing function

Abstract

The invention discloses a measuring device with an automatic picking and placing function. The device comprises a rack, a rotating mechanism, a curtain mechanism, a movement module and a lighting mechanism, wherein the rotating mechanism, the curtain mechanism, the movement module and the lighting mechanism are installed on the rack, the movement module comprises a sliding rail, the rotating mechanism is installed on the sliding rail and moves along the sliding rail, the rotating mechanism comprises a lens installation part and a rotating device, the lens installation part is used for installing a lens to be tested, and the rotating device is used for driving the lens to be tested to rotate; the curtain mechanism is arranged at one side of one end part of the sliding rail; and the lightingmechanism comprises a light source, and the light source is arranged in a mode of being matched with the curtain mechanism. The device can automatically rotate the tested lens in the testing process,thereby reducing the workload, reducing the labor cost, further being capable of improving the control precision for the rotating angle, and avoiding an error brought about by the manual rotation. Inaddition, a good test environment can be provided for lens testing through adopting the curtain mechanism.

Description

technical field

[0001] The present invention relates to the field of optical testing, and in particular, to an automatic pick-and-place measuring device. Background technique

[0002] When the camera lens forms a real image of an object, in addition to the imaging light, there are other non-imaging rays that diffuse on the image surface of the optical system. These non-imaging rays are called stray light (also called stray light). Stray light usually comes from radiation sources outside the system, internal radiation sources, and non-imaging light energy from scattering surfaces, such as reflected light from various refractive surfaces such as optical components and structural parts, reflected light from the inner wall of the instrument, diffuse reflection of the lens itself, or The reflection of the lens barrel may cause stray light. In addition, the problem of stray light may also occur due to dust contamination of optical parts, damage to optical components, glue leakage,...
