Description

Hollow-core fiber inner wall coating apparatus

Technical field

The utility model is related to a kind of coating apparatus, and in particular to a kind of hollow-core fiber inner wall coating apparatus.

Background technology

Hollow-core fiber is mainly used for energy transmission, is transmitted for X-ray, ultraviolet light and far infrared luminous energy.Hollow-core fiber Structure is that glass is made cylindrical shape, and fibre core and covering principle are identical as step change type, using light between air and glass Total reflection is propagated.Since the major part of light can be propagated in loss-free air, the communication function with certain distance.Hollow light Fibre is as very promising one of Transmission Fibers, with easily fabricated, flexibility is good, simple in structure, Infrared Transmission loss The clear advantages such as small, still, in order to preferably apply hollow-core fiber performance, how effectively hollow inner surface plated film to Make it in gas-sensitive sensor device, optical device etc. be applied successfully, is the technology for needing to be broken through studied in recent years One of.Its difficult point is that hollow core portion diameter usually from several microns to tens microns, is difficult with the methods of magnetron sputtering at it Inner surface forms a film, and how to improve the quality of forming film on hollow-core fiber inner wall, it is necessary to further consider.

Utility model content

In order to solve the above-mentioned technical problem, the utility model uses the following technical solution：

A kind of hollow-core fiber inner wall coating apparatus, including grain-clamping table and flow speed controller slidably connect two on grain-clamping table A optic fibre end clamper being oppositely arranged, two optic fibre end clampers can along its relatively or contrarily direction on grain-clamping table It slides, being additionally provided on grain-clamping table can be respectively acting on two optic fibre end clampers and it can be fixed on the positioning Distance adjusting means, optic fibre end clamper includes slide, and one is fixedly connected on slide and is clamped along two optic fibre ends The clamping pipe of device relative direction setting, is clamped in pipe and is equipped with an elastic hose, elastic hose can be such that hollow-core fiber is inserted into And natural resiliency deformation can be relied on to clamp hollow-core fiber, two clampings manage opposite one end respectively using its center line as the center of circle Multiple petaloid gripping blocks are arranged at intervals with around it, multiple petaloid gripping blocks, which surround, forms elastic clip collar, outside elastic clip collar Diameter gradually increases outward along clamping tube axis direction, is arranged in elastic clip collar there are one clamping ring, when clamping ring direction elasticity When clamping ring opening direction moves, clamping ring can oppress elastic clip collar so that elastic clip collar clamping position is in elastic hose Hollow-core fiber, flow speed controller is connected to a wherein elastic hose can control flow rate of liquid in elastic hose.

In the present invention, in use, clamping ring is first made to be directed away from the movement of elastic clip collar opening direction, bullet is avoided Compressing of the property clamping ring to elastic hose；Then the both ends of optical fiber are inserted respectively into the elastic hose of corresponding side, and The end of optical fiber is set to be located in elastic clip collar；Clamping ring is directly set to be moved towards elastic clip collar opening direction, due to elasticity The outer diameter of clamping ring towards opening direction gradually increases, then during clamping ring moves, clamping ring can be to elasticity Clamping ring is oppressed, and elastic clip collar is inwardly shunk, and final compressing is on elastic hose to be clamped to optical fiber.Clamping ring During oppressing elastic clip collar, each petaloid gripping block in elastic clip collar can be along clamping caliber to side To clamping force is applied, one straight state of folder is kept to optical fiber retained part while to fiber gripper.Then command range tune Regulating device makes two optic fibre end clampers be moved on grain-clamping table towards opposite direction, is stretched to optical fiber, in this way no matter It is optical fiber retained part or non-clamping part all in straight condition, corresponding plated film is passed through into the elastic hose of one end Liquid, and pass through flow speed controller（Peristaltic pump）The flow rate of liquid flowed through in optical fiber is controlled, makes liquid slowly in optical fiber Interior flowing, coating liquid do not interfere with fibre-optical bending thus and cause by being excluded from the elastic hose of the other end after hollow-core fiber The uneven phenomenon of film forming improves the quality of plated film.

As an optimization, the distance adjusting means include being located between two optic fibre end clampers and along two institutes State optic fibre end clamper relative direction setting screw pipe, screw pipe both ends be respectively arranged with it is coaxial and oppositely oriented Threaded rod, the both ends for screwing pipe orifice are respectively arranged with internal thread with its side threaded rod screw-thread fit, screw pipe Both ends be threaded togather respectively by internal thread and the threaded rod of its side, threaded rod is far from screwing one end of pipe It is fixedly connected with the optic fibre end clamper.Pipe is twisted by rotation, the threaded rod at both ends is respectively facing relatively or contrarily Direction movement, and then control two optic fibre end clampers relative position, it is simple in structure, it is easy to use.

As an optimization, bottom is also placed on the grain-clamping table has opening and by two optic fibre end clamper packets Hold temperature-controlled cabinet inside it, temperature-controlled cabinet and the fixation on the wherein side side wall of the clamping tube axis direction It is connected with heating plate, it is outer that the cable of heating plate passes through the temperature-controlled cabinet side wall in heating plate side to stretch out in, and in addition one Condenser pipe is fixedly connected on the side wall of side, the both ends of condenser pipe pass through the temperature-controlled cabinet side wall in condenser pipe side to stretch out In outer, temperature-controlled cabinet and the sidewall bottom positioned at the clamping tube axis direction rear and front end offer respectively can make it is described The recess that elastic hose passes through.Temperature-controlled cabinet is buckled on grain-clamping table, is clamped two optic fibre end clampers and thereon Optical fiber contains inside it, and the elastic hose at both ends is stretched out from the recess of corresponding side, then by controlling heating plate respectively（No More than 200 DEG C, avoid that optical fiber is caused to soften）Or condenser pipe, to increase or decrease temperature in temperature-controlled cabinet, to observe The plated film situation of hollow-core fiber under different temperatures.

In conclusion the beneficial effects of the utility model are：The utility model is simple in structure, easy to use, by hollow Optical fiber carries out coating operation after stretching fixation, avoids the generation of film forming uneven phenomenon, improves coating quality.
