Description

Technical Field

[0001] The utility model relates to the technical field of optical fiber array processing, in particular to an end surface grinding fixture. Background Art

[0002] Optical fiber arrays use V-groove substrates to precisely install one or more optical fibers at specified intervals to form an optical structure with specific functions. Optical fiber array grinding technology uses high-precision grinding tools and equipment to carefully polish the end faces of optical fiber arrays to improve the transmission quality and speed of optical fibers. During the grinding process, through continuous grinding and polishing, the surface of the optical fiber array becomes smoother, and the scattering and reflection of light are effectively reduced, thereby significantly improving the transmission efficiency and quality of light.

[0003] At present, for the grinding of optical fiber arrays, some factories use a clamping fixture to clamp a group of optical fiber arrays, and then use a grinder to grind the optical fiber array on the clamping fixture. Since only one group of optical fiber arrays can be ground at a time, the production efficiency is too slow. In view of this, we propose an end face grinding fixture. Utility Model Content
