The vertical lifting assembly is used to drive the alignment mechanism to move up and down, and the plane fine-tuning assembly is used to drive the swing rod of the elastic member to swing to complete the optical fiber alignment operation.

Description

technical field [0001] The invention relates to an alignment device suitable for fusion splicing of optical fibers with different fiber diameters. Background technique [0002] The fiber optic cable fusion splicer uses a high-voltage arc to melt the two optical fiber sections gently and promotes the fusion of the two optical fibers into one, so as to realize the coupling of the optical fiber mode fields. However, the existing optical fiber fusion splicer is only suitable for optical fibers of the same fiber diameter for fusion splicing operations, and cannot be directly spliced ​​for optical fibers of different fiber diameters, and the fusion effect is poor. The device to the same central position cannot meet the needs of various optical fiber fusion operations. SUMMARY OF THE INVENTION [0003] The technical problem to be solved by the present invention is to provide an alignment device suitable for fusion splicing of optical fibers of different fiber diameters with reas...
