We know that there are many advantages of optical fiber communication itself, but the connection is not as easy as wires, optical fiber welding machine is the use of arc discharge principle of optical fiber welding machine two, common optical fiber welding machine and its model, technical indicators SUMITOMO SUMITOMO single core TYPE -

15, 1, VIEW domestic series welding machine (
Nanjing Kuala Lumpur, electronic 41st institute, DVP)
Main features are: fast, automatic welding, compact structure, light, color display screen, can be observed at the same time the X, Y, optical fiber, small volume, light weight, provide storage function such as welding data, applied optical fiber type: SM, MM, DSF fiber can be.
Three, the optical fiber welding machine parts (
4, 1 welding process, tools: host, cutting knife, optical fiber, stripping pliers, alcohol,
Best industrial alcohol 99%, with 75% of medical alcohol can also)
Also can use tissues)
, heat shrinkable sleeve 2, discharge experiment: objective: to make optical fiber welding machine to adapt to the current environment: why do better adapt to the environment, discharge more fully, welding effect is better what to do: (
And join a fiber, choose 'discharge experiment' function, press 'SET' key to screen shows the intensity of discharge, discharge until 'OK'.
, air discharge, press the ARC to do how many times: process will appear 'too discharge, discharge the weak', until discharge: (OK to check what time do
, position change,
Generally more than 300 km)
And elevation changes (
Generally more than 1000 m)
, must need to do after replacing electrode discharge experiment (
, latitude change note: not every time before welding to do discharge experiment 3, confirm your welding of fiber types and need to be heated by the heat shrinkable sleeve type how to choose: optical fiber type: in welding mode choice SMF, MF, DSF, NZDF heat shrinkable sleeve type: in heating mode choice, general heat shrinkable casing, 60 mm two minutes and 40 mm, of course, there are manufacturers according to their production of optical fiber welding machine to customized heat shrinkable casing.
Don't let the phenomenon doesn't match the preparation of optical fiber, fiber core, the coating layer, packages, we have to weld is bare fiber, fiber core is with optical fiber wire stripping pliers stripping out a bare fiber, with alcohol cotton to clean, and then use optical fiber cutting knife to cut, to determine the cutting length according to the above parameters, cutting knife with the size scale, pay attention to keep the cutting face will remain vertical, error is less than 2 ° commonly, less than 1 °, pay attention to, clean before cutting!
Add 1: heat shrinkable tube, finish the action before cutting 4, welding fiber, cutting the fiber in optical fiber welding machines, put the position of: V groove end line center with the electrode rod straight 1/2 place among them, about!
Then put good optical fiber pressure plate, press foot,
On the other side)
Cover, wind cover, press SET key, start welding, the whole process need it takes about 15 seconds (
Different welding machine is different, the same)
, two amplification of optical fiber image appears on the screen, after the location of the focus, on a series of weld began after discharge, focal length adjustment action.
After completion of welding, put the HEAT shrinkable casing need fixed position, the welding parts of the fiber in the center of the HEAT shrinkable casing, the prevention must be put in the middle, gave him a certain tension, pay attention to don't let the noise of optical fiber bending, tension, pressure in the heating tank, cover, key HEAT, the following will flashing lights, lasts 90 seconds, the machine will warn heating process is complete, at the same time indicator light will keep flashing, take out the cooling, such a complete welding process is finished.
5, rearranging tools, in the location specified. When picking up trash, pick up note scrawled optical fiber head 6, often pay attention to the problems in the process,
, clean, optical fiber inside and outside of the welding machine, optical fiber itself, important is V groove, optical fiber in areas such as the presser foot.
, cutting, guarantee the cutting face 1 ° to 89 ° +, approximate vertical, in the process of put chopped fiber in the specified location, the optical fiber end face don't contact with any place, met you need us to clean, cut: emphasis on clean before cutting!
, optical fiber in its place, don't too far nor too near, 1/2, proficiency!
And in the whole process of welding, do not open the wind cover (
, heating heat shrinkable casing, process named in reinforcement of the place, when heated, optical fiber welding parts must be put in the middle, with a certain tension, to prevent the occurrence of bubble heating process, fixed the phenomenon such as inadequate, emphasizes the heating process and the welding process of the fiber can be simultaneously, took out after heating, don't touch the heating parts, after high temperature, to avoid danger.
And organizing tool, pay attention to the broken fiber ends, to prevent the danger, fiber glass, thin and very hard
