The welding process 2017-12-20

1, the tools:

Host, cutting knife, optical fiber, stripping pliers, alcohol (99% industrial alcohol is best, with 75% of medical alcohol can also be), cotton (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 work better

What to do:

(1) to join the optical fiber, choose "discharge experiment" function.The screen shows the discharge intensity, until discharge "OK".

(2) the air discharge, press the ARC to do: how many times will appear "too discharge, discharge process weak" OK, until discharge

What time do:

(1) change in position (generally more than 300 km)

(2) the elevation changes (generally more than 1000 m)

(3) after the replacement of electrode must discharge experiment needs to be done

(4) the latitude changes

Note: being not each time to do discharge experiment before welding

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 it do not match.

4, preparation of optical fiber

Optical fiber, fiber core, coating layer and cladding

We want to weld is bare fiber, is the fiber core, using 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

5, welding

Fiber, cutting the fiber in optical fiber welding machines, put the position of: V groove end line center with the electrode rod straight middle 1/2 place!And then put away fiber board, press foot (the same as in the other side), cover the wind cover, press SET key, begin to weld, the entire process takes 15 seconds or so (different welding machine is different, the same), two amplification of optical fiber image appears on the screen, after focusing, aim at the location of the 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 a hot bath, cover, and the 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.

6,

Finishing tool, in the location specified, picking up trash, pick up note scrawled optical fiber head

7, often pay attention to the problems in the process

(1) clean, optical fiber inside and outside of the welding machine, optical fiber itself, important is V groove, optical fiber presser foot and mirror etc.

(2) 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!

(3) optical fiber in its place, don't too far nor too near, 1/2, proficiency!

(4) in the whole process of welding, don't open the clear protective cover

(5), heating, heat shrinkable sleeve, the process of learning 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, the phenomenon such as insufficient fixed, 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.

(6) tools, pay attention to the broken fiber ends, to prevent the danger, fiber glass, thin and very hard

Second, general maintenance

Keywords: clean, dry

Cleaning tools (common) : cotton, cotton swabs, fiber itself, air bag, alcohol (ditto) need to clean the parts:

Optical fiber presser foot: dip in with cotton buds alcohol wipe according to the same direction

V groove: sumitomo special cleaning tools, no words can use alcohol bar, bare fiber can also be used to clean, general multi-purpose air balloon blowing, but avoid blowing with my mouth, did not have the moisture.

Clean V groove, welding machine adjustable scope of core driving up and down in the direction of the only tens of microns, foreign body slightly makes the fiber image deviates from the normal position, can't normal alignment.At this time should be timely clean V groove, the specific process is as follows:

1 > wind cap of welding machine.

2 > open the optical fiber head and holder plate.

3 > with cotton bar with anhydrous alcohol (or toothpicks sharpening) single direction wipe V groove, can.

Do note: avoid by all means use hard clean V groove or force the V groove, avoid bad V groove or make the V groove misalignment, instrument cannot be used properly.

For optical systems:

Composition: mirror protection

LED light

The CCD camera

Clean wipe with alcohol bar: for optical fiber cutting knife again, avoid objects in contact with the blade area

Third, consumables

Mainly is for the use of optical fiber cutting knife blades and discharge electrodes

The blade life: 16, cutting about 3000 times, each face life 48000 times (20) E -

The electrode life: general discharge more than 2000 times to be replaced

Do note: when cleaning, replacing electrode blade, everyday use is, to avoid any form of and blade electrode parts of the contact, is of great harm to itself!

Mr. Locke welding machine from Germany technology, high performance and perfect after-sales service to get consistent high praise at home and abroad, welcome customers to inquire fiber welding machine and optical fiber cutting knife, etc.
