Fine axial plane position tune.
In the utility model embodiment, since optical fiber has with ultraviolet light solidification, by acrylate, silicon rubber and nylon
One layer of elastic coating of equal compositions, is commonly called as coat, to keep cutting inconvenient, is based on this, the utility model passes through to coat
Increase the convenience of cutting in such a way that hot soarfing device strips；Specifically, refering to Fig. 5, the utility model is by by hot soarfing
The mode that device and cutter device combine solves the problems, such as this；Wherein, Milky Way electronics X9-J3030 heating dress is added under hot soarfing slot
It sets, and built-in temperature detecting resistance, optical fiber is heated, since the thermal expansion factor coefficient of optical fiber coating is significantly larger than interior
Portion enables the coat of optical fiber to be completely quickly stripped, and without any scratch.Cam drive at this time, which is moved through, to be come
Cutting blade be easier to completely cut it as requested；Cutter device uses 5 phase of east motor PKP523N12A-L type
For stepper as power source, the selection of motor in control system usually selects stepper motor and AC servo motor as driving
Motor.If selecting servo motor as driving, due to drawing cone platform relatively high for required precision, so the servo electricity selected
Machine needs biggish encoder line number to obtain lesser stepping angle, needs higher driver pulse frequency at the same time,
Though such scheme has the advantages that response is fast, stationarity is good, with high accuracy with respect to stepper motor, the side controlled it
Method is increasingly complex, cost is more；Although the drive system of stepper motor is usually used in opened loop control, with requirements for high precision
In the case where can use closed-loop control system, reliability be protected, and be equipped with retarder and be suitable for high-precision occasion, can be with
Assembling structure is relatively simple and cost is less, so extensional motion driving device selects the drive system of stepper motor.
It drives cutting blade to carry out linear movement to complete the cutting of optical fiber with cam structure, need to only design cam wheel appropriate
Exterior feature can make driven member obtain arbitrary desired movement, and structure is simple, compact, design is convenient.Cutting blade is Japan
Import blade after cutting angle is selected, is cut, impulse- free robustness after cutting by cam structure band cutting blade, and optical fiber section is clean
It is smooth.
Refering to Fig. 6, in the utility model embodiment, various dimensions displacement platform is mainly with X, tri- standard stereo coordinate of Y, Z
Axis direction is the overall movement direction of the present apparatus.Wherein with 5 phase step motors for main dynamic model block, it is preferred that in the present embodiment,

Screw rod is attached, then the SEBWL9G-100 for produce mobile platform in MISUMI company by the passive transmission of screw rod with
It is moved in SEB8G-40 model linear guide, to make the movement and conversion of single unit system completion space coordinate.The present apparatus
Using 5 phase stepper of east motor PKP523N12A-L type, installation dimension 28mm, excitation largest static torque 0.052N
M, rotor moment of inertia J are 9 × 10^-7kg m^2, and basic step angle is 0.72 °.Entire three-dimensional regulation wiener mobile device base
Platform has sliding steady, and the features such as minimum length is uniformly fine and closely woven is adjusted, and extremely meets this mechanical structure and overall space is sat
The mobile high precision requirement of mark.
Refering to Fig. 7, in the utility model embodiment, in order to guarantee picture quality that imaging fiber system obtains, this reality
With the novel principle using prism mirror based fiber optica internal light (spy lamp is kept in hot soarfing device folder lid, visits lamp after pressing from both sides lid and covering tightly
Light), the light in optical fiber is reflexed in the image procossing camera above focus by prism, is reached with this
To the purpose to welding angle state of observation fiber cross-sections.Due to having the requirement of lift in height, the present apparatus to prism
, as power source, diameter is driven by matched shaft coupling using by 5 phase stepper of east motor PKP523N12A-L type
It being rotated for the screw rod of 5mm, the quality of drive screw has a great impact for drawing cone speed, positioning accuracy, fit clearance,
Because small flighted screw has the characteristics that transmission efficiency is high, stationarity is good and high resolution, this structure selection screw pitch is
The two-way ball screw of 2mm.The quality of slide rail has very the quality of bearing capacity size and extensional motion stationarity
It is big to influence.So that the height of prism is gone up and down according to related request.The angle of prism can also be according to practical need
It is adjusted, by taking matched accurate thread pair, the disengaging of adjustment precision screw thread pair, so that prism is able to be pushed away
It is dynamic, so that the angle of prism be enable to adjust.
In summary, the working principle that full-automatic melting provided by the utility model picks are as follows: the optical fiber mixed up is put first
Onto cutter device, lamp is visited at this time and is lighted, so that the optical path of inside of optical fibre is illuminated, pass through podium level regulating device adjustment three
The height of prism so that light in optical fiber by the reflection of prism make the image in its section be reflected into above imaging fiber system
In system, by the analysis and the rotation of control rolling clamp of camera, so that optical fiber reaches the angle for being suitble to coupling, immediately
Camera in front of two optical fiber start to acquire image, whether conllinear, with one heart, then pass through three-dimensional dimension if then analyzing two light
Stage apparatus of receiving adjusts the space coordinate of two optical fiber, to make two optical fiber be adjusted to suitable spatial position, finally by three
Dimension wiener adjusts stage apparatus and makes two optical fiber close, and rattan storehouse discharge electrode discharges, and two optical fiber is made to complete coupling.
