Description

Technical Field

[0001] This utility model relates to the technical field of optical fiber cutting devices, and more specifically, to an optical fiber cutting device. Background Technology

[0002] In the development of optical fiber communication, sensing and other fields, optical fiber cutting is a key processing link, and its processing quality directly affects signal transmission efficiency and equipment performance.

[0003] A search revealed that Chinese patent CN218158414U discloses an automatic fiber optic cleaving device. This device addresses some shortcomings in existing fiber optic cleaving methods, such as the need for manual hand-chopping, which is inefficient and results in inaccurate cuts, affecting product quality. The new device uses a descending cleaving assembly to cut the fiber; that is, when the fiber moves to a certain position, the cleaving assembly cuts it, achieving precise positioning and cleaving of the cutting point. Simultaneously, it automatically fixes the fiber, improving the cleaving quality.

[0004] When faced with fiber optic cutting of different materials and thicknesses, it is impossible to adjust the tension according to actual needs. When cutting thicker or harder fibers, insufficient tension can cause the fiber to shift during the cutting process. When cutting thinner fibers, excessive tension may cause the fiber to break. Fiber slack can also cause uneven distribution of cutting force, resulting in a rough cut surface and burrs, which greatly reduces the quality and consistency of fiber optic cutting.

[0007] The fixing mechanism includes a movable block, which is disposed inside the cutting device box. A fixing groove is formed on the top surface of the movable block. A support column is fixedly connected to the top of the movable block. A top plate is fixedly connected to the top of the support column.

[0014] Preferably, optical fiber placement slots are provided on both sides of the cutting device box.

[0015] The technical effects and advantages of this utility model are as follows:

[0016] 1.

This improves the stability and reliability of the optical fiber fixing, thereby ensuring the precise position of the optical fiber during cutting and effectively improving the cutting accuracy. By moving the threaded sleeves away from or towards each other, the tension of the optical fiber can be flexibly adjusted according to different cutting requirements. On the one hand, when cutting thicker or harder optical fibers, the tension can be increased to prevent the optical fiber from shifting during the cutting process.

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0025] As attached Figure 1-5 The fiber optic cutting device shown includes a cutting device box 1, a fixing mechanism is provided inside the cutting device box 1, a movable tensioning mechanism is provided at the bottom of the cutting device box 1, and an adjustable cutting mechanism is provided at the top of the cutting device box 1.

[0026] The fixing mechanism includes a movable block 2, which is installed inside the cutting device box 1. A fixing groove 3 is provided on the top surface of the movable block 2. A support column 4 is fixedly connected to the top of the movable block 2. A top plate 5 is fixedly connected to the top of the support column 4. A threaded hole 6 is provided on the top surface of the top plate 5. A screw 7 is threadedly connected inside the threaded hole 6. A knob 8 is fixedly connected to the top of the screw 7. An arc-shaped clamping plate 10 is fixedly installed at the bottom of the screw 7. A bearing 9 is installed between the screw 7 and the arc-shaped clamping plate 10.

[0027] As attached Figure 1 , 2 As shown in Figures 3 and 5, the movable tensioning mechanism includes a fixed shell 11, which is fixed to the bottom of the cutting device box 1. A first motor 12 is fixedly installed on one side of the fixed shell 11. A threaded rod 13 is fixedly connected to the output end of the first motor 12. The threaded rod 13 is rotatably connected to the fixed shell 11. A threaded sleeve 14 is threadedly connected to the outside of the threaded rod 13. A connecting slider 15 is fixedly connected to the top of the threaded sleeve 14. Two sets of threads are symmetrically arranged on the outer surface of the threaded rod 13, which facilitates the rotation of the threaded rod 13 to drive the moving blocks 2 to move closer or further apart, thereby adjusting the fiber tension. A through groove 16 is provided on the bottom surface of the inner wall of the cutting device box 1. The through groove 16 is slidably connected to the connecting slider 15, which serves as a limit and prevents the moving blocks 2 from rotating with the threaded rod 13.

[0028] As attached Figure 1 , 2 As shown in Figure 4, the cutting mechanism includes an electric slide table 17, which is fixedly installed on the top of the cutting device box 1. A fixed frame 18 is slidably connected to the bottom of the electric slide table 17. A servo motor 23 is fixedly installed on one side of the fixed frame 18. A rotating shaft 19 is fixedly connected to the output end of the servo motor 23. The rotating shaft 19 is rotatably connected to the fixed frame 18. Two fixed plates 20 are fixedly connected to the bottom of the rotating shaft 19 to facilitate the adjustment of the angle of the cutting wheel 22, thereby achieving the cutting requirements of different angles.

[0029] As attached Figure 1 , 2 As shown in Figure 4, a cutting wheel 22 is installed between two fixed plates 20. A second motor 21 is fixedly installed on one side of one of the fixed plates 20. The output end of the second motor 21 is fixedly connected to the cutting wheel 22, so that the cutting wheel 22 can rotate to cut the optical fiber.

[0030] As attached Figure 1 , 2 As shown, optical fiber placement slots 24 are provided on both sides of the cutting device box 1 to facilitate the entry of optical fibers into the cutting device box 1 through the optical fiber placement slots 24.

[0031] The working principle of this utility model is as follows: The optical fiber to be cut is placed in the fixing groove 3 on the top of the moving block 2 as the basic positioning for fixing the optical fiber. By rotating the knob 8, the screw 7 is driven to rotate in the threaded hole 6. Due to the threaded connection between the screw 7 and the threaded hole 6, the screw 7 will move up and down. The arc-shaped clamping plate 10 installed at the bottom of the screw 7 through the bearing 9 will descend accordingly until the arc-shaped clamping plate 10 cooperates with the fixing groove 3, tightly clamping and fixing the optical fiber between the two. The setting of the bearing 9 ensures that the arc-shaped clamping plate 10 will not rotate with the screw 7 during the descent, ensuring stable clamping of the optical fiber.

[0032] The first motor 12 on one side of the fixed housing 11 is started. The first motor 12 drives the threaded rod 13 to rotate. Since the threaded rod 13 is rotatably connected to the fixed housing 11, and two sets of threads are symmetrically arranged on the outer surface of the threaded rod 13, the threaded sleeve 14 is threadedly connected to the threaded rod 13. When the threaded rod 13 rotates, the two threaded sleeves 14 will move in opposite or the same direction along the threaded rod 13. The connecting slider 15 at the top of the threaded sleeve 14 slides in the through groove 16 on the bottom surface of the inner wall of the cutting device box 1, thereby driving the entire fixing mechanism to move, realizing the tensioning or loosening operation of the optical fiber to adapt to different cutting needs. At the same time, tensioning the optical fiber can enhance the cutting effect and make the cutting surface more even.

[0033] The electric slide table 17 is fixed on the top of the cutting device box 1. The fixed frame 18 can be slid at its bottom by controlling the electric slide table 17, so as to adjust the position of the cutting mechanism in the horizontal direction. After the servo motor 23 on one side of the fixed frame 18 is started, it drives the rotating shaft 19 to rotate. The two fixed plates 20 at the bottom of the rotating shaft 19 rotate accordingly, thereby adjusting the angle of the cutting wheel 22 to meet the cutting requirements of different angles. When cutting is required, the second motor 21 is started. The second motor 21 drives the cutting wheel 22 to rotate at high speed. Under the coordinated action of the electric slide table 17 and the servo motor 23, the cutting wheel 22 performs the cutting operation on the fixed optical fiber.

[0034] In conclusion, the above embodiments are merely illustrative of the principles and effects of this utility model and are not intended to limit the scope of this utility model. Any person skilled in the art can modify or alter the above embodiments without departing from the spirit and scope of this utility model. Therefore, all equivalent modifications or alterations made by those skilled in the art without departing from the spirit and technical concept disclosed in this utility model should still be covered by the claims of this utility model.
