Description
Technical field
The utility model is related to a kind of device for stripping of fibre coating, are a kind of small to optical fiber superficial lesions specifically
Device for thermal ablation.
Background technology
It in the production process of optical passive component, needs to divest the coat of optical fiber, leaks out fibre cladding, then carry out again
Processing.Fibre coating, which divests mode, mechanical and chemical two class of fiber stripping, and mechanical fiber stripping mode will be applied using physics mode
Coating strikes off, and chemical formula fiber stripping mode is that the coat of optical fiber is corroded using chemicals, is existed using chemical formula fiber stripping
After peeling optical fibre coat, residual is had between coat and fibre cladding, the bonding of optical fiber coating and covering is destroyed, leads
Delamination is caused, makes fiber failure；Mechanical fiber stripping is divided into two kinds of non-heated formula and heated type, and the difference of heated type and non-heated formula is just
It is that before physics strikes off heating is carried out to optical fiber surface in advance enables the coat on its surface soften, either heated type also right and wrong
Heated type, in peeling optical fibre coat, always cutter always needs directly to be contacted with fibre cladding, to optical fiber gesture
A degree of damage must be caused, this damage can directly influence the reliability of optical fiber finished device.
Invention content
The purpose of this utility model is to provide a kind of completely new fibre coating device for stripping, hardly in optical fiber table
Face is left a trace, and utmostly ensure that the function of optical fiber is unaffected.
The utility model is realized using following technological means：A kind of novel low damage optical fiber heat-peeling forceps, including heating part, stripping
Except portion and driving portion, driving portion divests portion, heating part and is arranged in order, and the portion of divesting includes upper cutter head and lower cutter head, upper cutter head
It is U-shaped cutter head with lower cutter head, two U-shaped cutter heads be combined with each other as a tubular body, are set at the inside edge of tubular body
The knife edge, Urban Chaos include a heating chamber apart from 5 μm of fibre cladding surface, heating part, and heating chamber is cylindrical shape, in heating chamber
Outside setting heating unit, the interior diameter of heating chamber is slightly larger than the diameter of optical fiber, and heating cavity length is between 5-7cm, heating chamber
Distance divests portion 2-3cm, and the driving portion is an optical fibre winding device.
The diamond coated coating in knife edge surface, for diamond coatings thickness in 1-2mm, the heating unit is electric heating
Silk or ceramic heating device, heating temperature is at 70-90 DEG C, heating time 10-15s.
The utility model is compared with existing product, its cutter is not in contact with optical fiber surface first, can only be struck off
Coat on optical fiber, cutter and fibre cladding do not have tangible contact or contact is minimum, therefore it is greatly reduced
The damage amplitude of optical fiber, and it is more thorough except decree coat divests using hot soarfing.
Description of the drawings
FIG. 1 is a schematic structural view of the utility model.
Fig. 2 is divests portion's structure diagram.
Cutter head, 4- heating parts wherein under the upper cutter head of 1- optical fiber, 2-, 3-.
Specific embodiment
The utility model is described in further detail with reference to the accompanying drawings of the specification：
The utility model is related to a kind of device for stripping of optical fiber surface coat, are that one kind does not damage optical fiber specifically
The heat-peeling forceps of surface coverings are driving portion respectively including three parts, divest portion and heating part 4.Driving portion, divest portion with
Heating part 4 is set gradually, and optical fiber 1 is drawn by driving portion to be passed sequentially through heating part and divest portion, and the coat on 1 surface of optical fiber is first
Softening is first heated to, declines rapidly with the binding force of fibre cladding, is then removed coat by divesting portion.More have
Body says that driving portion is an optical fibre winding device, and connecting wire spool by a motor rolls up the optical fiber after stripping
Around, while the coiling action of coiler device also functions to the effect of a traction, and optical fiber is enabled endlessly to be stripped.
Since optical fiber is made of quartz fibre, if winding diameter is too small or traction of overrunning, optical fiber can be broken.Cause
This, the minimum diameter of wire spool cannot be less than 5cm, and in general the diameter of wire spool is controlled in 5-8cm, rotating speed at 15 revs/min
Clock.
The utility model dependence divests portion and strikes off the coat of the optical fiber surface after heating, specifically, described
The portion of divesting include upper cutter head 2 and lower cutter head 3, two cutter heads are the U-shaped structure that inside is equipped with the knife edge, two cutter head combination shapes
Into an annular, the direction of the knife edge is in face of fibre movement direction, i.e. the setting direction of the knife edge and fibre movement direction is on the contrary, point of a knife
It is configured perpendicular to optical fiber setting or the knife edge with optical fiber with 15-20 ° of angle, diamond coatings is coated on knife edge surface,
Utmostly ensure the service life of the knife edge, the thickness of coating is in 1-2mm.
Further, the Urban Chaos of the utility model has 5 μm of distance, in other words, the knife edge apart from fibre cladding surface
Coat can only be struck off, the knife edge is with the surface of fibre cladding without substantive contact, and it is hereby ensured that optical fiber packets
Layer it is intact, the possibility of optical fiber finished product is ensured.
Optical fiber can be heated to 70 DEG C -90 DEG C by the heating part 4 of the utility model, so as to which coat be enabled to soften rapidly, be reached
Convenient for the effectiveness divested, heating part 4 includes a heating chamber, and in the outside of heating chamber, setting heating unit heats it,
Heating chamber is columnar structured for length 5-7cm's, and metal, ceramics etc. can be used with good thermal conductivity attribute in heating chamber
The conventional heatings device such as heating wire can be used in material, heating unit.Heating part also sets up temperature control device and accurate control is carried out to temperature
System, it is ensured that the surface temperature of optical fiber reaches setting value.Optical fiber heats 10-15s in heating part in the utility model, slow to heat
Can enable heating it is more uniform, coat reaches minimum with fibre cladding binding force.
