Space ring, optical lens and assembling method thereof

Abstract

The invention provides a space ring, an optical lens and an assembly method of the optical lens, wherein the space ring comprises a space ring body and is further provided with at least one co-assembly part. The space ring body forms a light-transmitting space and is further provided with at least one co-installation part, an operation device supports the space ring body through the co-installation part, and the space ring body is installed on a lens cone. The operation device supports the space ring body through the co-installation part in a clamping or supporting fixing manner, and the spacering is installed between the two optical lenses in the lens cone through the operation device. When the space ring is clamped, because the space ring is supported by the plurality of stable triangles, the space ring is clamped very stably, and the space ring is prevented from being scraped with the side wall of the lens randomly during the process of being installed into the lens cone to generate dross so as not to influence the internal cleanliness of an optical system.

Description

technical field [0001] The invention relates to the field of lens processing and manufacturing, and more specifically, relates to a spacer, an optical lens and an assembly method thereof. Background technique [0002] Usually at least one spacer is needed between two lenses in the lens to maintain the optical distance between the lenses and prevent the lenses from colliding with each other, thereby better protecting the lenses in the lens. However, due to the special optical system and lens performance requirements of some lenses, the structure of the spacer changes accordingly, but no matter how the structure changes, the role of maintaining the optical gap will not change. [0003] With the advancement of technology, lens devices are becoming more and more sophisticated, and there may be multiple lenses or lens groups in one lens. For the assembly of lenses of multiple lens groups, generally at least one spacer is included between the lenses of each lens group to maintain...

AI Technical Summary

Problems solved by technology

The traditional jig that absorbs material in the form of breath is difficult to use for the hollow spacer or spacer-shaped workpiece, and the installation process is very unstable and easy to fall

[0004] If the clamping and assembly of the spacer is not stable, it is easy to scrape with the side wall of the lens barrel to generate slag, which will affect the cleanliness of the optical system

If the clamping and assembly of the spacer is unstable, it may also cause the optical lenses on both sides of the spacer to be installed unevenly, resulting in a gap between the optical lens and the spacer, thus affecting the optical stability of the lens

[0005] In addition, during the assembly process of the lens, if the assembly process is wrong or there is a deviation in the operation process, it will be difficult or impossible to remove the inserted spacer, which will cause the entire lens to be scrapped during the processing process, which will affect the quality of the lens.
