Description
Technical field
The present invention relates to fused fiber splice field, specifically suitable for different materials, the optical fiber welding of different core optical fibers weldings
The laser scanning heat welded that picks 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.
The content of the invention
In order to solve the problems, such as that prior art is present, the present invention provides a kind of optical fiber splicer laser scanning heat welded machine
Structure, 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 gathered
Jiao, the power that control laser exports realize the substep welding of different materials, different core optical fibers, realize the synchronous softening of optical fiber,
With the advantages of welding is quick, welding effect is good.
The present invention adopts the following technical scheme that:Optical fiber splicer laser scanning heat welded mechanism, including laser, it is special
Sign is:The laser output of laser is provided with galvanometer, and galvanometer front end is provided with field lens, the laser beam warp that laser is sent
Vibration mirror scanning and field lens form laser facula output after focusing 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 present invention is using the Gaussian beam that laser is sent as thermal source, for left and right different materials or different core diameters
Optical fiber, with different power realize that the synchronous of optical fiber softens when scanning and heating, while optical fiber propulsion electric machine promotes in real time, it is complete
Into 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 optical fiber splicer laser scanning heat welded mechanism of the present invention.
Embodiment
Embodiments of the invention are 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

The carbon dioxide laser 1 of the present invention is installed on optical fiber splicer, instead of the thermal source (electricity of existing fiber heat sealing machine
Arc), and galvanometer 2 and field lens 3 are installed at the laser output of carbon dioxide laser 1.Fused fiber splice process is:First by two
Section treats that the relative mode of the optical fiber M of welding and N-terminal face is clamped on the fixture of optical fiber splicer optical fiber propulsive mechanism, starts optical fiber
Optical fiber M and optical fiber N are advanced in visual field by propulsive mechanism, are judged two sections of optical fiber M and N material or core diameter and aligning, are opened and swash
Light device switchs, and the heat welded when promoting, laser exports different power according to the material or core diameter of two sections of optical fiber, realizes two
The synchronous softening of section optical fiber, and realize that the welding of optical fiber couples in progradation.
The laser scanning heat welded mechanism of the present invention can realize that different materials, the synchronous softening of different core optical fibers are molten
Connect, avoid the occurrence of cold joint interface, and fusion efficiency is high, product qualified rate is high.
Above-described is only one embodiment of the present invention.It should be pointed out that for one of ordinary skill in the art
For, under the premise without departing from the principles of the invention, some variations and modifications can also be made, these also should be regarded as belonging to this hair
Bright protection domain.
