Description
[technical field]
The present invention relates to a kind of bare fibre grinding technics more particularly to a kind of bare fibre batch grinding technics and methods.
[background technique]
It due to many advantages of optical signal, will be used wider and wider, but also higher and higher to the requirement of product simultaneously,
Either optic communication, Fibre Optical Sensor, high power laser or other light application fields, optical fiber are all the loads of optical signal transmission
Body, the quality of itself quality and its good and the bad that quality is docked with other devices, will have a direct impact on entire optical device or optical link,
The manufacturing process of optical fiber is highly developed, and at low cost and quality state is controllable, but fiber alignment technology is still in exploration, in majority
Be still main quality hidden danger point and work consuming time-consuming point in optical device and optical link, major influence factors first is that optical fiber is cut
The processing in face, i.e. the end surface grinding technology of bare fibre；
Existing bare fibre end face grinding technique mainly include the following types:
Using patent of invention CN106000983B and utility model patent CN107953153A as representative, using dedicated naked
Optic fiber polishing machine or ordinary optic fibre grinder cooperate naked fibre adapter, grind bare fibre by root, the defect of this method is single
An optical fiber can be ground, and optical fiber is clamped by mechanical system, be easy impaired；
Using patent of invention CN104015121A and utility model patent CN206536338U as representative, common grinding is used
Machine cooperates special abrasive disk, and the adhesives such as paraffin or glue are previously placed in the container of abrasive disk, by 1 after softening
Or multifiber insertion, optical fiber is solidified into one rear whole disk in abrasive disk and is ground, after-tack adhesive is completed in grinding, extracts light out
Fibre, then optical fiber cylinder and end face are cleaned, it is glue between optical fiber and abrasive disk though this method can once grind multifiber
The mode of water bonding is fixed, the bad control of angle, and can not determine eligible state before optical fiber extraction, can not single beam return mill.
[summary of the invention]
Present invention aims at solving, above-mentioned no fado root is ground, fiber angle control inaccuracy, optical fiber are easy to be undermined
Can not single beam return the deficiency of mill etc. and a kind of bare fibre batch grinding technics and method that provide.
