Spherical product gluing centering device

Abstract

The invention discloses a spherical product gluing centering device, which relates to the technical field of optical measurement. The spherical product gluing centering device comprises a mounting platform, a tool and at least two groups of adjusting structures, wherein the tool is arranged on the upper end face of the mounting platform and is used for placing a gluing lens, and the gluing lens comprises a gluing upper sheet and a gluing lower sheet which are arranged up and down; the adjusting structures are arranged on the mounting platform in different radial directions of the gluing lens respectively, each adjusting structure comprises a measuring assembly and an adjusting assembly, and the measuring assemblies and the adjusting assemblies are arranged in the same direction and located on the two sides of the gluing upper sheet respectively. The measuring assemblies and the adjusting assemblies can stretch out and draw back in the setting directions of the measuring assemblies and the adjusting assemblies so as to abut against the peripheral face of the gluing upper sheet. By means of the arrangement, the measuring assemblies and the adjusting assemblies are combined to abut against the periphery of the gluing upper sheet, the position of the gluing upper sheet is fixed, displacement in the measuring process is avoided, measuring deviation is reduced, repeated adjustment is not needed, the gluing difficulty is reduced, and the gluing efficiency is improved.

Description

technical field [0001] The invention relates to the technical field of optical measurement, in particular to a centering device for gluing spherical products. Background technique [0002] The cemented lens is made of two lenses of different materials glued together, which can correct the dispersion of the glass and eliminate the problem of chromatic aberration. The cemented lens is widely used in objective lens systems, imaging systems, and laser measurement systems. In order to ensure the coaxiality of the optical system, the centers of the two lenses must be on a straight line. [0003] During the gluing process of high-precision lenses, it is necessary to use a center deviation measuring instrument to measure while gluing to ensure that the center deviation is within the allowable range. After the center deviation measuring instrument has finished measuring, it will give the offset data of the center of each surface, and the operator can fine-tune the position of the gl...
