Description
Technical field
Fused fiber splice field is the utility model is related to, specifically suitable for different materials, the light of different core optical fibers weldings
Fine heat sealing machine laser scanning heat welded mechanism.
Background technology
With optic communication and the continuous development of photoelectron technology, the optical fiber constantly quilt of various novel optical fibers and different core diameters
Develop, the problem of thing followed is one very big is exactly that the connection between these different thicknesses and different materials optical fiber is asked
Topic.Use following two connection methods in industry substantially at present：
1st, cold joint：The optical fiber of different materials is aligned and fixed by the structure of machinery using ceramic insertion core and sleeve pipe
Together.This method Insertion Loss is big, return loss is also very poor, and costs dearly, and connection effect is poor, boundary be present between two optical fiber
Face, easily cause light and leaked in interface.
2nd, welding：Welding to different core optical fibers, burning-on method is mainly deviateed using electric arc at present：I.e. by thermal source (electric arc)
In fusion point slightly offset from being allowed to adapt to the equal heating effect in the fusion process of different thicknesses optical fiber, two sections of optical fiber are broken
Gently being promoted with high-precision motion mechanism while face is melted allows two optical fiber to be fused into one, to realize the coupling of optical fiber mode fields
Close.This method is extremely cumbersome, and every kind of optical fiber is required to substantial amounts of test data to support, and welding effect is poor, success rate
It is relatively low.
Utility model content
In order to solve the problems, such as that prior art is present, it is molten that the utility model provides a kind of optical fiber splicer laser scanning heating
Connection mechanism, thermal source of the heat welded mechanism by the use of laser as fused fiber splice, galvanometer and field lens are used for laser output scanning
And focusing, the power of control laser output realize the substep welding of different materials, different core optical fibers, realize that the synchronization of optical fiber is soft
Change, there is the advantages of welding is quick, welding effect is good.
The utility model adopts the following technical scheme that：Optical fiber splicer laser scanning heat welded mechanism, including laser,
It is characterized in that：The laser output of laser is provided with galvanometer, and galvanometer front end is provided with field lens, the laser light that laser is sent
Beam forms laser facula output after vibration mirror scanning and field lens focus on.
During the fused fiber splice of different materials or different core diameters, by two sections of optical fiber heating institute calorific requirements are different,
If the Synchronous Heating as former fused fiber splice, the asynchronous of both ends can be caused, it is difficult to welding, even if welding, effect
Also can be very undesirable.The utility model is using the Gaussian beam that laser is sent as thermal source, for left and right different materials or difference
The optical fiber of core diameter, realize that the synchronous of optical fiber softens when scanning heating with different power, while optical fiber propulsion electric machine pushes away in real time
Enter, complete the welding of optical fiber.
Further, described laser is gas laser, preferably carbon dioxide laser, the optical maser wavelength that it sends
For 10.6 μm, positioned at infrared region, due to the sensitiveness of fiber optic materials, inorganic oxide salt is sent to carbon dioxide laser
Optical band is more sensitive, using carbon dioxide laser as thermal source, disclosure satisfy that the welding of multiple material optical fiber.
Brief description of the drawings
Fig. 1 is the schematic diagram of the utility model optical fiber splicer laser scanning heat welded mechanism.
Embodiment
Embodiment of the present utility model is described specifically below in conjunction with the accompanying drawings：
Optical fiber splicer laser scanning heat welded mechanism, as shown in figure 1, including carbon dioxide laser 1, carbon dioxide
The laser output of laser 1 is provided with galvanometer 2, and the front end of galvanometer 2 is provided with field lens 3, the laser that carbon dioxide laser 1 is sent
Light beam forms laser facula output after the scanning of galvanometer 2 and field lens 3 focus on.
Carbon dioxide laser 1 of the present utility model is installed on optical fiber splicer, instead of the heat of existing fiber heat sealing machine
Source (electric arc), and galvanometer 2 and field lens 3 are installed at the laser output of carbon dioxide laser 1.Fused fiber splice process is：It is first
First the relative mode of the two sections of optical fiber for treating welding M and N-terminal face is clamped on the fixture of optical fiber splicer optical fiber propulsive mechanism, opened
Optical fiber M and optical fiber N are advanced in visual field by dynamic optical fiber propulsive mechanism, judge two sections of optical fiber M and N material or core diameter and aligning,
Laser switch is opened, the heat welded when promoting, laser exports different power according to the material or core diameter of two sections of optical fiber,
The synchronous softening of two sections of optical fiber is realized, and the welding coupling of optical fiber is realized in progradation.
Laser scanning heat welded mechanism of the present utility model can realize that different materials, the synchronization of different core optical fibers are soft
Change welding, avoid the occurrence of cold joint interface, and fusion efficiency is high, product qualified rate is high.
Above-described is only a kind of embodiment of the present utility model.It should be pointed out that the ordinary skill for this area
For personnel, on the premise of the utility model principle is not departed from, some variations and modifications can also be made, these also should be regarded as
Belong to the scope of protection of the utility model.
