Description
Technical field
The present invention relates to fused fiber splice field, especially a kind of optical fiber cutting method.
Background technology
Fiber cut technology is generally divided into two kinds at present.
One kind is first to mark the edge of a knife in optical fiber surface with knife, then applies pressure from the edge of a knife backwards to along the edge of a knife, make light
Fibre disconnects under the effect of the pressure;
Another kind is first to apply certain pulling force to optical fiber both ends, then knife is used to extrude the edge of a knife in optical fiber surface, and the edge of a knife exists
It is persistently deepened during the feeding of knife, when reaching certain depth, then under the action of two side draws, optical fiber breaks.
The use of both methods is all based on and all divests the coat of optical fiber, and divesting the optical fiber after coat becomes
Very it is crisp, it is easily broken, and diameter only have 125 microns (a kind of optical fiber, here illustrate size purpose be in order to illustrate optical fiber very
Carefully);
In above-mentioned first method, best depth of cut is generally 1/10 or so of fibre diameter, in this way to cutting
Relative altitude requirement between the shape and guide rail and both sides clamping face rubber of knife is very tight, and (optical fiber has optical fiber both sides clamping face
Clamping face, fixture also have clamping face) it is clamped by fixture, pass through rubber contact between fixture and optical fiber clamping face), too deep or mistake
The shallow section cut out is all not clean and tidy enough, influences welding quality;
This brings two problems, first, when climate change, the hardness of both sides rubber may change, and lead to clamped height
It changes, and then cutting-in is made to change, cause cutting effect bad, influence welding quality;Another situation be blade or
After the abrasion of person's sliding rail, causes the height of blade to change, need replacing blade and readjusted, this adjusting is typically
Very troublesome, site operation personnel are difficult to grasp, and can also influence welding quality, and most of cutter all use on the market at present
, all there are these in this method, be never resolved, and influence the transmission that welding quality eventually results in follow-up optical fiber
Rate loss is very big, especially on main line, can not being subject to so big loss.
Second, pulling force is previously applied on optical fiber both sides, then feed generates the edge of a knife, since the diameter of optical fiber only has 125
Micron, and after stripping coat, become very crisp, it is frangible, since diameter is too small, it is clamped again not pinch off, it is right
The selection requirement of material is very high, and when it is clamped, clamping face needs are made very smooth, while having again enough
Frictional force, this is very difficult, mostly uses the expensive V-shaped slot clamping face of high-precision (fixture and first way difference greatly at present
It is, is grip optical fiber surface and simultaneously as two laybacks here, so clamping face is not elastomer, it is the higher hard table of precision
Face);For tool parts, there was only ultrasonic cutting knife and some very high-end cutters in this way at present, price ratio
Using the fiber cut cutter of the first method, expensive tens times.
It must clean if even if using the expensive V-shaped slot clamping face of these high-precisions in use, slightly fall at any time
Dust is on clamping face, and clamping face squeezes dust when clamping, the corresponding part contacted with dust on optical fiber can be caused compared with
Big stress may result in fibercuts, therefore require operating environment high;
In addition to this issue, the cutter of non-ultrasonic is after optical fiber is tensed, knife under the effect of the pressure,
Optical fiber surface extrudes the edge of a knife, therefore the requirement to cutter is also unusual height, and only seldom producer can process this essence at present
The cutter of degree, so this kind of cutter is at present on the market without universal, difficulty of processing too it is high cause it is expensive.
Meanwhile in some patents, a kind of cutting method for not shelling coat is also referred to, but current fused fiber splice
Machine, mainstream are all that can only use to divest the optical fiber after coat, the optical fiber major part optical fiber splicer that this method is cut into
It can not use;
Even if being first cut into optical fiber in this way, coat is then shelled again, after cleaning, very maximum probability coat
Residue can be gathered in fiber end face, even if also being difficult to remove using alcohol, it is difficult control to be carried out at the same time the clean electricity of pre-arcing,
The bump that coat residue would generally be burnt on fiber end face, influences welding quality, the transmission rate of follow-up optical fiber is caused to be damaged
Consumption is very big, especially on main line, can not being subject to so big loss.
Invention content
In view of the problems of the existing technology, goal of the invention of the invention is to provide a kind of clamping face reducing clamping piece
Required precision is to increase the success rate of fiber cut to the requirement of operating environment when reducing the cost, reduce cutting and then increase
Efficiency is added to reduce the optical fiber cutting method of cost.
To achieve the goals above, the technical solution adopted by the present invention is:
A kind of optical fiber cutting method comprising step:
A, the outside of peeling optical fibre external structure, the Duan Jie where making optical fiber need cut place only remains coated with layer;
B, at least one end of optical fiber is clamped, needs the coat around cut place to divest optical fiber;
C, the both ends saved by described section carry out clamping and clamping piece applies pulling force to optical fiber, in the institute for having divested coat
Stating optical fiber needs cut place to cut optical fiber.

It is compared with the first way described in background technology, the first way is cut using after clamping,
Then fibercuts is made backwards to pressure is applied along the edge of a knife to the edge of a knife, so it needs the clamping of optical fiber to use elastomer
(rubber), with this come bear to the edge of a knife backwards to apply pressure along the edge of a knife when give rubber optical fiber radial direction power, prevent
Fibercuts, therefore a series of problems in the background technology can be deposited, the application by the way of tensioning fracture, using with background skill
Mode similar in the second way in art does not have to the scheme using rubber in background technology, there is no in background technology when
Between long rubber hardness a series of problems, such as changing;
But when divesting coat due to it, an intermediate part is only divested, the clamping piece at both ends is clamped in not when clamping
On the coat divested, the second way in the background technology that compares, due to by coat grip optical fiber, not being clamped directly
To optical fiber surface, the clamping face of clamping piece requires the V-shaped slot clamping face for not having to reach high-precision costliness in background technology then such
Height can also achieve the effect that the not broken optical fiber of clamping, can substantially reduce cost, meanwhile, operating environment is required also significantly

The cutter of kind of mode, since cylinder blade is to maintain rotation, so its optical fiber is not had to it is pure by pressing as in background technology
Power carries out the extrusion edge of a knife (such knife must be very sharp in background technology, and machining accuracy is very high, of high cost), cylinder blade
Processing request is lowered, and reduces cost, while comparing ultrasonic wave cutter, and cost is much lower, and in 201210539579X,
A kind of blade rotation is referred in 201280013805.9, but purpose is to be not configured to rotation in order to replace cut surface and formed
Cutting.
As the preferred embodiment of the present invention, in step A, before carrying out the peeling optical fibre external structure, pass through it is mobile eventually
Outer fiber color and coding is identified in the photographic device at end, forms characteristic, and judge light according to characteristic
Fine type, then the information of optical fiber is transferred to cutter, so that cutter in step B, C is corresponded to using matching optical fiber
Machined parameters, such as the mobile terminal are mobile phone, then the data needed in script cutting machine can be made to be handled by external device,
The manufacture requirement of cutting machine is reduced, or even cancels the CPU of script in cutting machine, reduces cost.
As the preferred embodiment of the present invention, in step B, the coat carries out the optical fiber surface for divesting part after divesting
Alcohol cleans, and is that optical fiber surface is cleaner, and follow-up cutting and welding effect are more preferable.
The beneficial effects of the invention are as follows:
The application and the maximum difference of the prior art are, when divesting coat, only divest an intermediate part, then two
The clamping piece at end is clamped on the coat not divested, and tensioning is carried out to optical fiber;
It is compared with the first way described in background technology, the first way is cut using after clamping,
Then fibercuts is made backwards to pressure is applied along the edge of a knife to the edge of a knife, so it needs the clamping of optical fiber to use elastomer
(rubber), with this come bear to the edge of a knife backwards to apply pressure along the edge of a knife when give rubber optical fiber radial direction power, prevent
Fibercuts, therefore a series of problems in the background technology can be deposited, the application by the way of tensioning fracture, using with background skill
Mode similar in the second way in art does not have to the scheme using rubber in background technology, there is no in background technology when
Between long rubber hardness a series of problems, such as changing;
But when divesting coat due to it, an intermediate part is only divested, the clamping piece at both ends is clamped in not when clamping
On the coat divested, the second way in the background technology that compares, due to by coat grip optical fiber, not being clamped directly
To optical fiber surface, the clamping face of clamping piece requires the V-shaped slot clamping face for not having to reach high-precision costliness in background technology then such
Height can also achieve the effect that the not broken optical fiber of clamping, can substantially reduce cost, meanwhile, operating environment is required also significantly
