Description

Technical Field

[0001] The utility model relates to a laser optical fiber array coupling component, in particular to a small laser optical fiber array coupling component, and belongs to the technical field of optical fiber array coupling components. Background Art

[0002] With the continuous advancement of science and technology, laser technology is moving towards miniaturization and integration. Miniaturized lasers are not only easier to install and use, but also effectively reduce system cost and complexity. Fiber coupling technology enables low-loss transmission of laser beams in optical fibers, effectively extending the laser's service life and transmission distance. Fiber array coupling components are one of the key means of achieving high-power fiber lasers. By coupling the beams emitted by multiple small lasers into a fiber array, higher output power and better beam quality can be achieved.

[0003] The existing small laser fiber array coupling assembly has a simple structure. Before each use, the position of the optical fiber and the coupling lens needs to be debugged and fixed so that the coupling lens focuses on the optical fiber. If the laser shakes, the position of the optical fiber will deviate, requiring repeated debugging, which not only wastes time but also causes poor coupling accuracy. Utility Model Content

[0004] In view of the shortcomings of the existing technology, the utility model provides a small laser fiber array coupling assembly, which can focus the coupling lens on the optical fiber without having to debug or fix the positions of the optical fiber and the coupling lens before each use.

[0005] The technical solution adopted by the present invention to solve the above technical problems is:

[0006] A small laser fiber array coupling assembly includes a laser body and a fiber coupling assembly body. The laser body is mounted with a fiber body. The fiber coupling assembly body is provided with a clamping structure. The clamping structure includes multiple electric telescopic rods fixedly mounted on the fiber coupling assembly body. The output ends of the electric telescopic rods are mounted with clamping guards. The electric telescopic rods are provided with multiple mounting holes. Springs are fixedly mounted within the mounting holes. A clamping block is fixedly mounted at one end of the spring. The clamping guard is provided with a mounting groove that is compatible with the output ends of the electric telescopic rods. The inner wall of the mounting groove is provided with multiple clamping holes for use with the clamping blocks.

[0007] Furthermore, one end of the clamping block is configured to be arc-shaped.

[0008] Furthermore, a protective plate is provided on the main body of the optical fiber coupling component, an air inlet is opened on the protective plate, and a delivery pipe is provided above the air inlet.

[0009] Furthermore, a plurality of fastening collars are provided on the outer side of the air inlet, and the plurality of fastening collars are connected by a bidirectional screw rod. A plurality of fixing blocks connected to the bidirectional screw rod are fixedly installed on the top of the protective plate.

[0010] Furthermore, a plurality of slide grooves are provided on the protective plate, and a slider connected to the fastening ring is movably installed inside the slide groove.

[0011] Furthermore, a plurality of connection holes are provided on the main body of the optical fiber coupling assembly and the protective plate, and an insertion rod is movably installed inside the connection hole, and a clamping plate is fixedly installed on one end of the insertion rod.

[0012] Furthermore, a plurality of grip rods are fixedly mounted on the other end of the insertion rod.

[0013] Compared with the prior art, the present invention has the following beneficial effects:

[0014] The present application sets up a clamping structure, and the coupling lens can be focused on the optical fiber without debugging and fixing the position of the optical fiber and the coupling lens before each use. At the same time, multiple electric telescopic rods are started to drive the clamping guards to move closer to each other. After the multiple clamping guards are closed, the optical fiber body can be fixed; the clamping block is engaged in the clamping hole under the elastic action of the mounting hole, thereby fixing the clamping guard on the electric telescopic rod to prevent it from falling off. Pulling the clamping guard causes the clamping block to be squeezed and contracted into the inside of the mounting hole. After the clamping block is detached from the clamping hole, the clamping guard can be disassembled and replaced, which is convenient for disassembly and assembly of the clamping guard; after the multiple clamping guards clamp and fix the optical fiber body, the position of the optical fiber will not deviate even if the laser shakes, reducing the number of times it is debugged, not only saving time but also improving the accuracy and stability of coupling.

[0021] The technical solution of the present invention will be described clearly and completely below with reference to the accompanying drawings and specific embodiments.

[0022] like Figure 1-Figure 5 A small laser fiber array coupling assembly shown includes a laser body 1 and a fiber coupling assembly body 2. An optical fiber body 3 is mounted on the laser body 1. A clamping structure 4 is provided on the fiber coupling assembly body 2. The clamping structure 4 includes multiple electric telescopic rods 5 fixedly mounted on the fiber coupling assembly body 2. A clamping guard plate 6 is mounted on the output end of the electric telescopic rod 5. The electric telescopic rod 5 has multiple mounting holes 7. A spring 8 is fixedly mounted inside the mounting hole 7. A clamping block 9 is fixedly mounted on one end of the spring 8. The clamping guard plate 6 has a mounting groove 10 adapted to the output end of the electric telescopic rod 5. The inner wall of the mounting groove 10 is provided with multiple clamping holes 11 for use with the clamping block 9. By setting the clamping structure 4, there is no need to debug and fix the position of the optical fiber and the coupling lens before each use, and the coupling lens can be focused on the optical fiber; at the same time, multiple electric telescopic rods 5 are started to drive the clamping guard plates 6 to move closer to each other. After the multiple clamping guard plates 6 are closed, the optical fiber body 3 can be fixed, and the clamping block 9 is engaged in the clamping hole 11 under the elastic action of the mounting hole 7, thereby fixing the clamping guard plate 6 on the electric telescopic rod 5 to prevent it from falling off; pulling the clamping guard plate 6 causes the clamping block 9 to be squeezed and contracted to the inside of the mounting hole 7. After the clamping block 9 is disengaged from the clamping hole 11, the clamping guard plate 6 can be disassembled and replaced, which is conducive to the installation and disassembly of the clamping guard plate 6; after the multiple clamping guard plates 6 clamp and fix the optical fiber body 3, the position of the optical fiber will not deviate even if the laser shakes, reducing the number of times it is debugged, not only saving time but also improving the accuracy and stability of the coupling.

[0023] like Figure 4 As shown, one end of the clamping block 9 is set to be arc-shaped to reduce the friction force at one end of the clamping block 9, making it easier for the clamping block 9 to slide inside the clamping guard plate 6, thereby facilitating the disassembly and installation of the clamping guard plate 6.

[0024] like Figure 1As shown, a protective plate 12 is provided on the optical fiber coupling assembly body 2, and an air inlet 13 is formed on the protective plate 12. A delivery tube 14 is provided above the air inlet 13. The arrangement of the protective plate 12, the air inlet 13, and the delivery tube 14 can protect the optical fiber body 3 and the optical fiber coupling assembly body 2, preventing them from being accidentally damaged by contact. Moreover, when the optical fiber coupling assembly body 2 is used in a harsh environment, such as a low-temperature environment or a high-temperature environment, hot air or cold air can be selectively delivered to the bottom of the protective plate 12 to maintain the optical fiber coupling assembly body 2 at a suitable temperature at all times, thereby preventing the environment from affecting the coupling efficiency.

[0025] like Figure 1 As shown, the outer side of the air inlet 13 is provided with a plurality of fastening rings 15, and the plurality of fastening rings 15 are connected by a bidirectional screw rod 16. The top of the protective plate 12 is fixedly installed with a plurality of fixing blocks 17 connected to the bidirectional screw rod 16; at the same time, the plurality of bidirectional screw rods 16 are rotated to drive the plurality of fastening rings 15 to approach each other until the fastening rings 15 clamp the delivery pipe 14 to prevent the delivery pipe 14 from detaching from the protective plate 12 when delivering gas. The bidirectional screw rod 16 is rotated to drive the fastening rings 15 away from each other to loosen the delivery pipe 14, thereby detaching the delivery pipe 14.

[0026] like Figure 5 As shown, the protective plate 12 is provided with a plurality of slide grooves 18, and a slider 19 connected to the fastening ring 15 is movably installed inside the slide groove 18. The arrangement of the slide groove 18 and the slider 19 can reduce the friction between the fastening ring 15 and the protective plate 12, making the fastening ring 15 more labor-saving during the movement and facilitating the fastening and loosening of the fastening ring 15.

[0027] like Figure 2 As shown, a plurality of connection holes 20 are provided on the main body 2 of the optical fiber coupling component and the protective plate 12. A plug rod 21 is movably installed inside the connection hole 20, and a clamping plate 22 is fixedly installed at one end of the plug rod 21. The plurality of plug rods 21 are inserted into the interior of the connection hole 20 until the protective plate 12 and the main body 2 of the optical fiber coupling component are connected together. Then, the plug rod 21 is rotated so that the clamping plate 22 is engaged with the groove inside the connection hole 20, so that the protective plate 12 can be fixed on the main body 2 of the optical fiber coupling component to prevent it from loosening. The plug rod 21 is rotated again so that the clamping plate 22 is disengaged from the groove inside the connection hole 20, and the plug rod 21 can be pulled out, which facilitates the disassembly and replacement of the protective plate 12.

[0028] like Figure 2 As shown, a plurality of grips 23 are fixedly mounted on the other end of the insertion rod 21 . The provision of the grips 23 can increase the force-bearing area of ​​the other end of the insertion rod 21 , making it easier for the operator to rotate the insertion rod 21 .

[0029] The working process of the small laser fiber array coupling assembly provided in this embodiment is as follows:

[0030] At the same time, multiple electric telescopic rods 5 are started to drive the clamping guard plates 6 to move closer to each other. After the multiple clamping guard plates 6 are closed, the optical fiber body 3 can be fixed. The clamping block 9 is engaged in the clamping hole 11 under the elastic action of the mounting hole 7, thereby fixing the clamping guard plate 6 on the electric telescopic rod 5 to prevent it from falling off; pulling the clamping guard plate 6 causes the clamping block 9 to be squeezed and contracted to the inside of the mounting hole 7. After the clamping block 9 is disengaged from the clamping hole 11, the clamping guard plate 6 can be disassembled and replaced; after the multiple clamping guard plates 6 clamp and fix the optical fiber body 3, the position of the optical fiber will not deviate even if the laser shakes, reducing the number of times it is debugged and improving the coupling efficiency and stability.
