Description

Technical Field

[0001] The present invention belongs to the technical field of optical fiber splicing, and particularly relates to an optical fiber splicer for communication engineering with a dust-proof function. Background Art

[0002] An optical fiber splicer refers to an optical fiber splicer used in the field of optical communication, which is mainly used for the construction and maintenance of optical cables in optical communication, so it is also called an optical cable splicer. It is an instrument and equipment that combines optics, electronic technology and precision machinery. Its working principle is to align two optical fibers through an optical fiber alignment system first, and then fuse the two optical fibers into one by a high-voltage arc emitted by an electrode to achieve the coupling of the optical fiber mode field. The optical fiber splicer can obtain a fiber splicing joint with low loss, low reflection, high mechanical strength and long-term stable reliability, so it is widely used in the field of communication engineering.

[0003] An optical fiber splicer is a machine widely used in the construction of optical cable lines, the production of optical devices and the research related to optical fiber communication in scientific research. It can perform precise optical fiber welding operations. However, the main working environment of the optical fiber splicer is outdoors, and there are many impurities such as dust and powder in the environment where it is located. During the working process, impurities often fall on the operation area or the display screen of the optical fiber splicer. If impurities fall into the operation area, it will lead to a reduction in the accuracy of optical fiber welding, and if impurities fall on the display screen, it will affect the alignment and splicing situation when observing the splicing of two optical fibers in the optical fiber splicing area on the display screen. And, according to investigation and research, the main problems existing in the existing optical fiber splicers during operation are: (1) During the construction process, the staff needs to carry many tools such as an optical fiber splicing machine box, an optical fiber splicing tool box, a power supply panel, etc. to the construction site. The number of tool boxes is large and the weight is heavy. Especially during outdoor construction, the staff needs to carry the above tools over a long distance, which greatly consumes the physical strength of the staff, is easy to get tired, and will also reduce their work efficiency. (2) The optical fiber splicing work is restricted by the on-site working environment conditions and can only use a newspaper laid flat on the ground as the working platform. The staff needs to bend down for a long time to carry out the optical fiber splicing work. This working method is very tiring and is prone to lumbar muscle strain in the long term, and it also affects the work efficiency. (3) When using the ground plane as the working platform, due to the large amount of dust generated during work, it is easy to cause optical fiber contamination, which in turn leads to a reduction in the success rate and quality during splicing.

[0004] In summary, how to prepare an optical fiber splicer that is convenient to carry and has a dust-proof function is a technical problem that those skilled in the art urgently need to solve. Summary of the Invention

[0005] To solve the above problems in the prior art, the present invention provides an optical fiber fusion splicer for communication engineering with a dust-proof function. The optical fiber fusion splicer studied in the present invention has a strong dust-proof function and is small in size and easy to carry, solving the problems existing in the prior art and being suitable for wide promotion and application.

[0006] To achieve the above object, the present invention provides the following technical solutions:

[0007] The present invention provides an optical fiber fusion splicer for communication engineering with a dust-proof function. The optical fiber fusion splicer includes a main body and a dust-proof cover, and the main body and the dust-proof cover are connected by a rotating shaft; a stripping assembly and a fusion assembly are provided on the surface of the main body;

[0008] The stripping assembly includes a positioning channel. One end of the positioning channel is provided with an inlet opening. Electric boxes are arranged on both sides of the inlet opening. The electric boxes are connected to spring rods, and the other ends of the spring rods are connected to a first push plate. A stripping knife is provided on the first push plate; an automatic cutting machine, a filter screen and a dust collector are sequentially arranged at the outlet of the positioning channel;

[0009] The stripped optical fiber is sent to the fusion assembly for fusion. The fusion assembly includes a base, a second push plate and a fusion arc; the base is provided with a positioning groove, and the optical fiber is placed along the positioning groove for fusion. A fusion interface is also provided on the base, and the fusion arc fuses the optical fiber through the fusion interface;

[0010] An imaging system is arranged on the inner side of the dust-proof cover.

[0011] Beneficial effects: For the optical fiber fusion splicer prepared by adopting the above technical solutions, when the optical fiber fusion splicer is not in use, the dust-proof cover is put down to prevent impurities and dust in the environment from falling on the fusion splicer and affecting the work. And during use, since the working environment is relatively complex, there are a large amount of dust and impurities at the work site, and dust is likely to fall on the optical fiber fusion splicer, which is likely to block the imaging observation screen, thereby affecting the monitoring of the optical fiber fusion situation by the staff. Therefore, the present invention installs the imaging system on the inner side of the dust-proof cover. During the working process, the side wall of the dust-proof cover can further block dust for the imaging system. Moreover, the present invention installs the imaging system on the dust-proof cover, and its angle can be freely adjusted, which is not only more convenient to observe the fusion situation during the working process, but also saves the physical strength of the staff and can reduce the occupied area of the optical fiber fusion splicer.

[0012] When the present invention is in use, the optical fiber to be skinned is fed into the positioning channel, and then the push plate 1 pushes the skinning knife into the inlet provided at the positioning channel, so as to perform a transverse cut on the optical fiber. Moreover, the present invention is provided with two symmetrical skinning knives, which can perform a more complete cut on the optical fiber, not only improving the working efficiency, but also further reducing the damage rate to the internal optical fiber. Moreover, during the cutting process, debris will inevitably be generated. If it is not cleaned up in time, the working process will be suspended, affecting the working progress. Therefore, the present invention is also provided with a filter screen and a dust collector. This device can clean debris and other impurities at any time during the working process, that is, the dust collector is aligned with the cutting position, and the impurities can be sucked away by the dust collector, and the large-particle substances among them can be blocked by the filter screen, so as to avoid damaging the dust collector due to the large particle size in the long term.

[0013] Further, in the skinning assembly, the skinning knife is pushed by the push plate 1 and extends into the inlet to cut the outer skin of the optical fiber.

[0014] Further, after the optical fiber is skinned, its end is cut by an automatic cutting machine to obtain a flat welding end.

[0015] The core materials at the cut position of the skinned optical fiber are uneven, which will cause the core materials of the two optical fibers not to be aligned during the subsequent welding process, thereby affecting the welding efficiency. Therefore, in order to solve this problem, the present invention is provided with an automatic cutting machine. After the skinned optical fiber is pulled out of the positioning channel, it is immediately cut to obtain a flat optical fiber welding end, so as to facilitate welding in the later stage and greatly improve the welding efficiency.

[0016] Further, a material placing box is arranged at the bottom of the filter screen in the skinning assembly.

[0017] The material placing box is used to hold the large-particle substances remaining after being filtered by the filter screen. After being intercepted by the filter screen, they directly fall into the material placing box for collection; small-particle substances such as dust directly pass through the filter screen and are sucked away by the dust collector.

[0018] Further, the dust collector is connected to the plate for placing the positioning channel through a rotating shaft 2.

[0019] In order to achieve all-round dust removal of the optical fiber welding machine, the present invention is provided with a rotating shaft between the dust collector and the plate for placing the positioning channel, which can make the dust collector rotate freely, so as to achieve dust removal of other parts of the optical fiber welding machine and ensure that the optical fiber welding machine is always in a normal working state.

[0020] Further, a motor is provided on one side of the second push plate in the welding assembly, which can push the second push plate towards the positioning groove during operation, so that the peeled optical fiber moves into the positioning groove, improving the welding efficiency.

[0021] Further, the welding arc is connected to the support frame through the first rotating shaft, and wires are arranged in the support frame to supply power to the welding arc. The welding arc can freely adjust its direction through the rotating shaft to adjust the welding angle.

[0022] Furthermore, a storage box is provided on the support frame. When the welding arc is not in use, it can be stored in the storage box. Moreover, the support frame can be placed flat on the main body, reducing the overall height of the optical fiber fusion splicer and the volume of the fusion splicer.

[0023] Furthermore, a buckle and a push rod are arranged in the electric box, and the spring rod extends into the electric box and is connected to the push rod. For optical fibers of different model specifications, even if their outer diameters are the same, the thicknesses of their outer sheaths (i.e., the jacket and the coating layer), the cladding, and the core layer are different. When peeling them, the best effect is to peel off the jacket and the coating layer without damaging the cladding and the core layer. Therefore, in the present invention, by arranging a push rod and a buckle in the electric box, the distance pushed by the push rod is selected according to the actual required cutting thickness during operation, so that the depth of the peeling knife piercing into the optical fiber is different to adapt to the peeling requirements of the optical fiber. After selecting the distance, move the push rod so that the buckle tightly abuts against the inner wall of the electric box, thereby playing a role in fixing the peeling knife, ensuring that the jacket and the coating layer are completely removed without damaging the cladding and the core layer of the optical fiber, greatly improving the peeling efficiency and quality, and making it more convenient to use.

[0024] Compared with the prior art, the present invention has the following beneficial effects:

[0025] When the present invention is in use, first insert the optical fiber to be peeled into the positioning channel, and then push the peeling knife into the inlet by moving the push rod in the electric box so that the peeling knife pierces into the outer skin of the optical fiber. Then, when the optical fiber is pulled out, the peeling knife cuts through the outer skin of the optical fiber, and after pulling out, tear off the cut outer skin. By providing a peeling assembly on the main body, the outer skin of the optical fiber can be conveniently peeled off before welding without carrying a separate peeling tool, facilitating the use of the fusion splicer. Moreover, the present invention cuts the outer skins on both sides of the optical fiber simultaneously, further greatly improving the peeling efficiency.

[0026] The present invention is provided with a dust removal device on the main body of the fusion splicer, which can further avoid the problem of low fusion splicing efficiency caused by a complex working environment and large pollution. And the present invention is provided with a dust-proof cover on the fusion splicer, which can be freely opened and closed through a rotating shaft. It can not only play a dust-proof role, but also the present invention arranges the imaging system inside the dust-proof cover, which not only greatly reduces the volume of the fusion splicer, but also can avoid dust falling on the imaging system and affecting the observation of the fusion splicing process. Moreover, this optical fiber fusion splicer can realize the functions of cutting optical fibers and fusion splicing while having a compact structure. There is also a handle on the dust-proof cover, with a small volume and complete functions, which is more convenient to carry, convenient for on-site work, and at the same time has the advantages of high cutting efficiency, good cutting quality, and good fusion splicing quality.

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0033] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments.

[0034] To make the above objects, features, and advantages of the present invention more obvious and understandable, the present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0035] From Figures 1-4 A fiber optic fusion splicer for communication engineering with a dust-proof function as shown, includes a main body (1) and a dust-proof cover (2); the main body (1) and the dust-proof cover (2) are connected by a rotating shaft, can be freely opened and closed, and the opening degree of opening and closing can be freely selected, which is convenient for operation and observation;

[0036] A peeling component (A1) and a fusion splicing component are arranged on the surface of the main body (1), so that two sections of optical fibers can directly enter the fusion splicing component for fusion splicing into a complete optical fiber after peeling. This device is an integrated machine for peeling and fusion splicing;

[0037] The peeling component (A1) includes a positioning channel (17). One end of the positioning channel (17) is provided with an inlet (16), and electric boxes (13) are respectively arranged on both sides of the inlet (16). Then the electric box (13) is connected to a spring rod (14), the other end of the spring rod (14) is connected to a first push plate (15), the first push plate (15) is further connected to a peeling knife (18). A buckle (25) and a push rod (26) are arranged in the electric box (13). The push rod (26) pushes the spring rod (14), so that the first push plate (15) pushes the peeling knife (18) into the inlet (16) to cut the outer skin of the optical fiber in the positioning channel (17); An automatic cutting machine (23), a filter screen (19), and a dust collector (21) are sequentially arranged at the outlet of the positioning channel (17). A discharge box (20) is arranged at the bottom of the filter screen (19). During the cutting process, large particles of impurities are intercepted by the filter screen (19) and enter the discharge box (20), and small particles such as dust are absorbed by the dust collector (21);

[0038] Put the two ends of the above-mentioned skinned optical fibers into the fusion splicing component for fusion splicing. The fusion splicing component includes a base (9), a second push plate (5) and a fusion arc (8). The base (9) is provided with a positioning groove (24). Place the two sections of optical fibers that have been skinned at the skinning component (A1) along the positioning groove (24) for fusion splicing. Before fusion splicing, the second push plate (5) is pushed by a motor (6) to make the optical fibers to be fused spread flatly in the positioning groove (24), so that the two fusion ends are at the fusion interface (7) for more convenient fusion splicing; the base (9) is provided with a fusion interface (7). Among them, the fusion arc (8) fuses the two sections of optical fibers through the fusion interface (7);

[0039] An imaging system (3) is provided inside the above-mentioned dust-proof cover (2), and the fusion splicing situation of the optical fiber can be observed at any time on this system.

[0040] In a further optimized solution, the dust collector (21) in the skinning component (A1) is connected to the plate where the placement positioning channel (17) is located through a second rotating shaft (22), so that the dust collector (21) can rotate freely to remove dust on the fusion splicer in all directions.

[0041] In a further optimized solution, the fusion arc (8) in the fusion splicing component is connected to the support frame (12) through a first rotating shaft (10). The support frame (12) is provided with a storage box (11), and the fusion arc (8) can be stored in the storage box (11) of the support frame (12). The support frame (12) can also be laid flat on the surface of the main body (1) to reduce the volume of the fusion splicer, and the fusion arc (8) can be freely adjusted in direction to adjust the welding angle.

[0044] In actual work, place this optical fiber fusion splicer on a flat surface, then open the dust cover (2) to the required angle that facilitates observing the imaging situation through the imaging system (3) on the dust cover (2). Feed the optical fiber into the positioning channel (17), and then turn on the electric box (13) to insert the stripping knife (18) into the inlet (16) on the positioning channel (17). Since the specifications of the optical fibers are different and the thickness of the outer layer wrapped thereon varies, select an appropriate depth according to the specifications of the optical fiber used, that is, insert the stripping knife (18) into the inlet (16) through the push rod (26) and the buckle (25) in the electric box (13). After determining the depth, fix it through the buckle (25), and then cut the sheath and coating layer of the optical fiber. Cut the end of the optical fiber sent out from the outlet of the positioning channel (17) with an automatic cutting machine (23). During this period, turn on the dust collector (21) to remove the impurities generated during the cutting process and ensure a clean cutting environment. Then pull the optical fiber outwards. When pulling, the outer skin of the optical fiber (i.e., the sheath and coating layer) breaks, and the stripping operation can be completed. Place the two stripped optical fibers on the positioning groove (24) of the fusion splicing component, turn on the motor (6), and neatly spread the optical fibers on the positioning groove (24) by pushing the second push plate (5). Start the fusion arc (8) to fuse the two ends of the optical fibers extending into the fusion interface (7), and a complete optical fiber can be obtained.
