Optical lens light guide transmission structure

Abstract

The invention discloses an optical lens light guide transmission structure comprising a mounting head and a front light guide head arranged at one end of the mounting head, a light passing plate is arranged on the inner side of one end of the front light guide head, and a gear cover mechanism is arranged on the inner side of the light passing plate; the gear cover mechanism comprises a rotating outer ring rotationally mounted on the gear cover mechanism, an adjusting inner ring rotationally mounted in the light passing plate, a pushing rod rotationally mounted on the adjusting inner ring and a dustproof blocking piece rotationally mounted at one end of the pushing rod, and the dustproof blocking piece corresponds to a light passing hole in the inner side of the light passing plate in position; and the inner side of the adjusting inner ring is fixedly connected with the rotating outer ring, and one side of the light passing plate is fixedly connected with a limiting ring. Through the designed light passing plate and the gear cover mechanism, the position of the dustproof blocking piece is adjusted through the gear cover mechanism in the using process, the through hole in the inner side of the light passing plate is opened, closed and blocked through the dustproof blocking piece, the light passing plate does not need to be disassembled, the loss phenomenon is prevented, and shooting cannot be affected.

Description

technical field [0001] The invention belongs to the technical field of optical lenses, and in particular relates to a light guiding transmission structure of an optical lens. Background technique [0002] The optical lens is an essential part of the machine vision system, which directly affects the quality of the image and affects the realization and effect of the algorithm. Optical lenses can be divided into short-focus lenses, medium-focus lenses, and telephoto lenses in terms of focal length; wide-angle, standard, and telephoto lenses in terms of field of view. Optical industrial lenses are widely used in the positioning and detection of highly reflective objects, such as: scratch detection on the surface of metal, glass, film, wafers, etc., damage detection of chips and silicon wafers, MARK point positioning, glass cutting machine, dispensing Industrial precision alignment, positioning, part confirmation, dimension measurement, industrial microscope and other CCD visual...

Problems solved by technology

[0003] When the existing optical lens is used, the internal light guide transmission structure is usually protected by a dust cover, and the dust cover is usually used alone, and it is easy to lose the dust cover during use. There will be problems affecting shooting on the lens, so we propose an optical lens light transmission structure
