Abstract
The invention relates to the technical field of corrosion of optical fibers and particularly relates to a device for achieving smooth and tapered corrosion of surfaces of optical fibers. The device is characterized in that a separation groove, a reaction groove and a washing groove are sequentially formed in one side of an optical fiber corrosion groove, wherein an optical fiber hole communicated with the optical fiber corrosion groove is formed in the side wall of each of the separation groove, the reaction groove and the washing groove; the axes of the optical fiber holes are overlapped; an adsorption layer is arranged in the separation groove and at least comprises two layers of wax paper and water absorption paper by alternatively overlapping; when the device is used, the optical fibers are corroded to be thinned by a hydrofluoric acid solution in the optical fiber corrosion groove; after the different parts of the optical fibers and hydrofluoric acid can react for different time by the movement of optical fibers to be corroded, so that different diameters are obtained and the tapered optical fibers are formed, and the smooth treatment on the corroded surfaces of the optical fibers is achieved; and dangers, which are possibly caused by the hydrofluoric acid in an optical fiber corrosion process, to operators are avoided.
Description
Technical field
The present invention relates to fiber optical corrosive technical field, especially a kind of device realizing the corrosion of optical fiber surface smooth taper of simple to operate, use safety.
Background technology
Fiber optical corrosive has become in various fiber optic applications the process means that (to comprise optical fiber laser field, sensory field of optic fibre etc.) conventional.But shaggy problem easily appears in the optical fiber after corrosion, thus directly affect the performance of its place device.In order to solve corrosion rear surface this problem coarse, usually need to proceed post-processing operation.But, hydrofluoric acid (HF) have severe toxicity and volatile, easily operator are worked the mischief in post-processing stages.Therefore, how carrying out the smooth corrosion of optical fiber surface is safely a technical problem urgently to be resolved hurrily in the industry.
Summary of the invention
Technical problem solved by the invention overcomes the deficiencies in the prior art, provides a kind of device realizing the corrosion of optical fiber surface smooth taper of simple to operate, use safety.
The scheme that the present invention takes for technical solution problem:
A kind of device realizing the corrosion of optical fiber surface smooth taper, comprise fiber optical corrosive groove, it is characterized in that fiber optical corrosive groove side is provided with obstruct groove, reactive tank, rinse bath successively, the sidewall of rinse bath, reactive tank, obstruct groove is respectively provided with an optic fibre hole be connected with fiber optical corrosive groove, the axes coincide of optic fibre hole, be provided with adsorption layer in obstruct groove, adsorption layer is at least alternately formed by stacking by two-layer paraffin paper and thieving paper, fully to adsorb the hydrofluoric acid (HF) of optical fiber surface.
The present invention can have the optic fibre hole be connected with fiber optical corrosive groove, the axes coincide of optic fibre hole, to increase work efficiency on the sidewall of rinse bath, reactive tank, obstruct groove.
Fiber optical corrosive groove of the present invention, obstruct groove, reactive tank and rinse bath are respectively equipped with closing cap, to guarantee use safety.
When the present invention uses, optical fiber is inserted in fiber optical corrosive groove by optical fiber, again respectively to fiber optical corrosive groove hydrogen injecting fluoric acid (HF) solution, to reactive tank hydrogen injecting sodium oxide (NaOH) solution, deionized water is injected to rinse bath, optical fiber is attenuated by hydrofluoric acid solution corrosion in fiber optical corrosive groove, wait that the movement of corroding optical fiber makes optical fiber different sites have the different reaction times from hydrofluoric acid (HF), obtain different diameters, thus formation conical fiber, adsorption layer in obstruct groove absorbs hydrofluoric acid (HF) solution on optical fiber, hydrofluoric acid solution is prevented to enter reactive tank, sodium hydroxide (NaOH) solution in reactive tank gets rid of hydrofluoric acid (HF) solution residual on optical fiber by chemical reaction, finally by the deionized water in rinse bath, reacted optical fiber is cleaned, obstruct groove, reactive tank and rinse bath also realize the process of fiber optical corrosive smooth surface, and avoid hydrofluoric acid in fiber optical corrosive process to the danger that operator may cause.
accompanying drawing illustrates:
Fig. 1 is a kind of structural representation of the present invention.
Fig. 2 is the A-A sectional view of Fig. 1.
Embodiment
Below in conjunction with accompanying drawing, technical scheme of the present invention is described further.
A kind of device realizing the corrosion of optical fiber surface smooth taper, comprise fiber optical corrosive groove, fiber optical corrosive groove is generally square or rectangle, fiber optical corrosive groove side is provided with obstruct groove successively, reactive tank, rinse bath, rinse bath, reactive tank, obstruct groove opposed optical fibers etching tank can make very narrow, obstruct groove, reactive tank, the sidewall of rinse bath be respectively provided with an optic fibre hole be connected with fiber optical corrosive groove and form a string optic fibre hole, optic fibre hole string is linearly, the axes coincide in each hole, adsorption layer is provided with in obstruct groove, adsorption layer is alternately formed by stacking by least two-layer paraffin paper and thieving paper, also can be formed by stacking by the layering of Dagwood formula, sandwich style layering is combined by " paraffin paper-thieving paper-paraffin paper ", fully to adsorb the hydrofluoric acid (HF) of optical fiber surface, in addition, fiber optical corrosive groove of the present invention, obstruct groove, reactive tank and rinse bath are respectively equipped with closing cap, to guarantee use safety.
Fig. 1 shows structural representation of the present invention, multilayer " paraffin paper-thieving paper-paraffin paper " sandwich structure adsorption layer 5 is inserted in obstruct groove 2, to wait that corroding optical fiber finally enters in etching tank 1 through sandwich structure in each aperture on optical fiber surface treatment trough and obstruct groove 2, can adjust and treat the length of corrosion optical fiber in fiber optical corrosive groove 1, then to hydrogen injecting sodium oxide (NaOH) solution in reactive tank 3, deionized water is injected again in rinse bath 4, hydrogen injecting fluoric acid in the most backward etching tank 1, corrosion starts, simultaneously with manually or motorized precision translation stage pull and treat that corrosion optical fiber is to away from etching tank 1 direction at the uniform velocity or accelerate mobile, what so just can realize waiting corroding optical fiber is etched into taper, adsorption layer 5(sandwich structure in obstruct groove 2 in the present invention) prevent and enter reactive tank due to hydrofluoric acid (HF) solution and partially absorb hydrofluoric acid on optical fiber (HF) solution, sodium hydroxide (NaOH) solution in reactive tank 3 gets rid of hydrofluoric acid on optical fiber (HF) solution by chemical reaction, finally by the deionized water in rinse bath 4, reacted optical fiber is cleaned.Wait that the movement of corroding optical fiber makes optical fiber different sites have the different reaction times from hydrofluoric acid (HF), obtain different diameters, thus form conical fiber.
Simplicity of design of the present invention, can realize the smooth corrosion of optical fiber surface, and avoids hydrofluoric acid in fiber optical corrosive process to the danger that operator may cause.Every equivalents of carrying out on technical solution of the present invention basis and improvement, all should not get rid of outside protection scope of the present invention.
