Description

Technical Field

[0001] This utility model relates to the field of multi-core optical fiber cutting technology, and in particular to a cutting machine suitable for multi-core optical fibers. Background Technology

[0002] Multi-core fiber optic cleavers are high-precision cleaving devices adapted for multi-core optical fibers. Their core function is to create a flat and smooth end face for multi-core optical fibers to meet the needs of subsequent fusion splicing or connection. They first use special clamps to accurately fix the optical fiber and prevent core misalignment, and then use diamond blades to apply uniform force or energy along the preset surface to achieve vertical burr-free cutting. They are widely used in optical communication and data centers to solve the cutting problem of high-density multi-core optical fiber connections, thus differentiating themselves from ordinary cleavers that are only designed for single-core optical fibers.

[0003] The multi-core fiber optic cleaver has micron-level high-precision cleaving capabilities, ensuring that the end face of each fiber core in a multi-core fiber remains flat, smooth, and highly consistent, effectively preventing misalignment of individual fibers from affecting subsequent splicing quality. Furthermore, when paired with a dedicated clamp, it can stably fix ribbons and bundles, completing the cleaving of multiple fiber cores in a single operation, eliminating the need for individual processing and significantly improving work efficiency. In addition, it is compatible with multi-core fibers of different specifications.

[0004] Multi-core fiber optic cleavers cannot adjust the angle according to the cutting requirements of multi-core fibers with different arrangements. They can only cut in a fixed direction, making it difficult to cope with non-standard cutting scenarios and drastically reducing their ability to process special-specification fibers. At the same time, the scope of application is narrowed. In complex fiber optic connection scenarios that require end-face processing of the same fiber in different directions, they cannot meet diverse needs and often require additional equipment, thereby increasing operating costs and time.

[0018] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings. 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. Reference Figure 5 An embodiment of this utility model is provided: a cutting machine suitable for multi-core optical fibers, including a base 1, a blade sliding plate 2 is provided inside the base 1, a multi-angle cutting mechanism 3 is provided on the top of the blade sliding plate 2, the multi-angle cutting mechanism 3 is used to cut optical fibers at multiple angles, and a clamping mechanism 4 is provided on the top of the base 1, the clamping mechanism 4 is used to fix the optical fiber to be cut. The multi-angle cutting mechanism 3 includes a blade table 31, the bottom of which is fixedly connected to the top of the blade sliding plate 2. A cutting chamber 32 is provided on the rear side of the base 1. A cutting blade 33 is slidably connected to the top of the blade table 31. A push block 34 is fixedly connected to the top left side of the blade sliding plate 2. A fiber take-up box 35 is fixedly connected to the rear side inside the cutting chamber 32. A sliding plate limiting component 37 is provided at the bottom of the blade sliding plate 2. A blade fixing component 38 is provided at the bottom of the cutting blade 33. Specifically, when cutting multi-core optical fibers, the optical fiber to be cut is fixed by the clamping mechanism 4 to ensure that the optical fiber will not be displaced during the cutting process, laying the foundation for subsequent precise cutting. After the optical fiber is fixed, the push block 34 is operated. Since the push block 34 is fixedly connected to the top left side of the blade sliding plate 2, the blade sliding plate 2 can be moved inside the base 1 by pushing the push block 34. During the movement of the blade sliding plate 2, the sliding plate limiting component 37 set at its bottom will limit the movement trajectory and range of the blade sliding plate 2 to prevent the blade sliding plate 2 from deviating during the movement and ensure that the blade sliding plate 2 can move stably according to the preset path. As the blade sliding plate 2 moves, the blade table 31 fixedly connected to its top moves synchronously, thereby driving the cutting blade 33 slidably connected to the top of the blade table 31 to move. During the movement of the cutting blade 33, the blade fixing component 38 set at its bottom will fix the position of the cutting blade 33 to prevent the cutting blade 33 from becoming loose or shifting in position during movement and cutting, ensuring that the cutting blade 33 can maintain a stable cutting state. When the cutting blade 33 moves into the cutting chamber 32 opened at the rear of the base 1 and comes into contact with the optical fiber to be cut, the cutting blade 33 begins to cut the optical fiber, realizing multi-angle cutting of the optical fiber. The optical fiber waste generated during the cutting process will fall into the fiber collection box 35 fixedly connected at the rear of the cutting chamber 32. The fiber collection box 35 collects the optical fiber waste to avoid the waste from scattering and affecting the operation of the equipment and the cleanliness of the working environment.

[0019] Reference Figures 1-3 The clamping mechanism 4 includes a hinge 41, the bottom of which is fixedly connected to the top left side of the base 1. A large pressure plate 42 is fixedly connected to the left side of the hinge 41. An upper pad 43 is fixedly connected to the right side of the large pressure plate 42. Two lower pads 44 are fixedly connected to the top rear side of the base 1. A clamp fixing assembly 45 is provided on the top right side of the large pressure plate 42. An optical fiber fixing assembly 46 is provided on the top front side of the base 1. An optical fiber pressure plate assembly 47 is provided on the top of the base 1. Specifically, when fixing the optical fiber to be cut, the optical fiber is first placed on top of the two lower pads 44 fixedly connected to the rear of the base 1. The lower pads 44 provide a support base for the optical fiber. Then, the large pressure plate 42 is pressed down with the hinge 41 as the rotation fulcrum. Since the bottom of the hinge 41 is fixedly connected to the top left side of the base 1, and the large pressure plate 42 is fixedly connected to the left side of the hinge 41, pressing the large pressure plate 42 can drive it to rotate around the hinge 41 until the upper pad 43 fixedly connected to the right side of the large pressure plate 42 contacts the surface of the optical fiber. At this time, the clamp fixing component 45 set on the top right side of the large pressure plate 42 is operated to lock the position of the large pressure plate 42, preventing the large pressure plate 42 from loosening during the optical fiber fixing process, and realizing the upper pad 43 and the lower pad 44 on the optical fiber. After clamping and fixing in the downward direction, the fiber optic fixing component 46 located on the front top of the base 1 is activated. The fiber optic fixing component 46 limits the position of the fiber tip to prevent displacement in the left and right directions. At the same time, the fiber optic pressure plate component 47 located on the top of the base 1 is operated to further press and fix the side of the fiber to prevent displacement in the vertical direction. The locking of the large pressure plate 42 by the clamp fixing component 45 and the limiting of the fiber tip by the fiber optic fixing component 46 achieve stable fixing of the fiber in the vertical and horizontal and front and back directions. The pressing of the fiber optic pressure plate component 47 on the side of the fiber and the clamping action of the upper pad 43 and the lower pad 44 finally achieve stable fixing of the fiber to be cut in all directions, providing a guarantee for the precise cutting of the fiber by the subsequent cutting blade 33.

[0020] Reference Figures 4-5 The cutting blade 33 is made of diamond. The top of the blade holder 31 has multiple grooves 36 arranged in a cross pattern. The sliding plate limiting assembly 37 includes two sliders 371. The tops of the two sliders 371 are fixedly connected to the bottom of the blade sliding plate 2. The bottom of the blade holder 31 has two locking grooves 372. The bottoms of the two sliders 371 are slidably connected to the inside of the locking grooves 372. The blade fixing assembly 38 includes a slide rail bracket 381. The top of the slide rail bracket 381 is fixedly connected to the bottom of the cutting blade 33. The bottom of the cutting blade 33 is slidably connected to the inside of the grooves 36. The top of the outer wall of the blade holder 31 has an annular opening 382. The inner wall of the annular opening 382 is slidably connected to a fixing ring 383. Specifically, before performing fiber optic cutting, the position of the cutting blade 33 on the blade holder 31 is adjusted according to the required cutting angle. Since the top of the blade holder 31 has multiple cross-shaped grooves 36, and the bottom of the cutting blade 33 is slidably connected to the inside of the grooves 36 through the slide rail bracket 381, pushing the cutting blade 33 can make it move along the grooves 36. Through the guiding effect of the cross-shaped grooves 36 and the slide rail bracket 381, the position of the cutting blade 33 can be adjusted at multiple angles. After the cutting blade 33 is adjusted to the preset cutting position, the fixing ring 383 slidably connected to the inner wall of the top ring 382 on the outer wall of the blade holder 31 is rotated. The position of the cutting blade 33 is locked by the fixing ring 383 and the slide rail bracket 381 to prevent the cutting blade 33 from moving along the grooves 36 during the cutting process. When the cutting operation begins, the push block 34 is pushed to move the blade sliding plate 2. The two sliders 371 fixedly connected to the bottom of the blade sliding plate 2 slide along the two locking grooves 372 opened at the bottom of the blade table 31. The movement trajectory of the blade sliding plate 2 is restricted by the sliders 371 and the locking grooves 372 to prevent the blade sliding plate 2 from deviating. As the blade sliding plate 2 moves, the blade table 31 drives the cutting blade 33 to move towards the optical fiber. Since the cutting blade 33 is made of diamond material, it can smoothly contact the optical fiber and cut it. The locking of the cutting blade 33 by the fixing ring 383 and the limiting of the blade sliding plate 2 by the sliders 371 and the locking grooves 372 ensure that the cutting blade 33 moves stably along the preset trajectory, and finally achieves precise cutting of the optical fiber.

[0021] Reference Figures 1-3 The clamp fixing assembly 45 includes a fixing block 451, the left side of which is fixedly connected to the top right side of the large pressure plate 42. A magnet 452 is fixedly connected to the top right side of the base 1. The fiber fixing assembly 46 includes a fixing seat 461, the bottom of which is fixedly connected to the front top of the base 1. A guide groove 462 is provided on the top of the fixing seat 461. The fiber pressure plate assembly 47 includes a rotating shaft 471, the top of which is fixedly connected to the rotating shaft 471. A fiber clamp 472 is rotatably connected inside the rotating shaft 471. Specifically, when fixing the optical fiber to be cut, the optical fiber is first placed on the two lower pads 44 on the rear side of the top of the base 1, and the front end of the optical fiber extends into the guide groove 462 opened on the top of the fixing seat 461. The front end of the optical fiber is initially positioned by the guide groove 462. Then, the large pressure plate 42 is pressed down with the hinge 41 as the rotation fulcrum. The large pressure plate 42 drives the upper pad 43 fixedly connected to its right side to move down synchronously until the upper pad 43 is in close contact with the surface of the optical fiber. At this time, the fixing block 451 fixedly connected to the top right side of the large pressure plate 42 moves with the large pressure plate 42 to the top right side of the base 1 above the magnet 452 fixedly connected to it. The position of the large pressure plate 42 is fixed by the magnetic attraction between the fixing block 451 and the magnet 452, preventing the large pressure plate 42 from loosening upward during the optical fiber fixing process, and realizing the clamping and fixing of the optical fiber in the vertical direction by the upper pad 43 and the lower pad 44. Next, the fiber optic clamping plate assembly 47 is operated. Since the top of the fixed base 461 is fixedly connected to the rotating shaft 471, and the inside of the rotating shaft 471 is rotatably connected to the fiber optic clamp 472, the rotating shaft 471 rotates downward to rotate the fiber optic clamp 472 until the fiber optic clamp 472 contacts the surface of the fiber inside the guide groove 462. The fiber optic clamp 472 and the guide groove 462 limit the left and right directions of the fiber to prevent displacement. The fixing block 451 and the magnet 452 magnetically attract and fix the fiber, and the upper pad 43 and the lower pad 44 clamp the fiber to achieve stable fixation in the up and down directions. The fiber is also stably fixed in the left and right directions, and finally the fiber to be cut is stably fixed in all directions, which provides a guarantee for the precise cutting of the subsequent cutting blade 33.

[0022] Working principle: The optical fiber to be cut is placed on top of the two lower pads 44 fixedly connected to the rear of the base 1. The lower pads 44 provide a supporting foundation for the optical fiber, while the front end of the optical fiber extends into the guide groove 462 opened on the top of the fixing seat 461. The guide groove 462 initially positions the front end of the optical fiber to prevent the front end from shifting during subsequent fixing operations. Then, the large pressure plate 42 is pressed down with the hinge 41 as the rotation fulcrum. Since the bottom of the hinge 41 is fixedly connected to the top left side of the base 1, and the large pressure plate 42 is fixedly connected to the left side of the hinge 41, pressing the large pressure plate 42 can drive it to rotate around the hinge 41, thereby driving the upper pad 43 fixedly connected to the right side of the large pressure plate 42 to move downward synchronously until the upper pad 43 is in close contact with the surface of the optical fiber. At this time, the fixing block 451 fixedly connected to the top right side of the large pressure plate 42 moves with the large pressure plate 42 to the top right side of the base 1 above the magnet 452 fixedly connected to the top. The fixing block 451 and the magnet The magnetic attraction of 452 fixes the position of the large pressure plate 42, preventing it from loosening upwards during fiber fixing. This achieves clamping and fixing of the fiber in the vertical direction by the upper pad 43 and the lower pad 44. Then, the fiber pressure plate assembly 47 is operated. Since the top of the fixing seat 461 is fixedly connected to the rotating shaft 471, and the inside of the rotating shaft 471 is rotatably connected to the fiber clamp 472, the rotating shaft 471 rotates downward to rotate the fiber clamp 472 until the fiber clamp 472 contacts the surface of the fiber inside the guide groove 462. The fiber clamp 472 and the guide groove 462 limit the fiber in the left and right directions, preventing the fiber from shifting. Through the magnetic attraction of the fixing block 451 and the magnet 452 and the clamping of the upper pad 43 and the lower pad 44, the fiber is stably fixed in the vertical direction and in the left and right directions. Finally, the fiber to be cut is stably fixed in all directions, ensuring that the fiber will not shift during the cutting process, laying the foundation for subsequent precise cutting. After the optical fiber is fixed, the cutting preparation stage begins. This involves adjusting the position of the cutting blade 33 according to the required cutting angle. Since the top of the blade holder 31 has multiple cross-shaped grooves 36, and the bottom of the cutting blade 33 is slidably connected to the inside of the grooves 36 via a slide rail bracket 381, pushing the cutting blade 33 allows it to move along the grooves 36. Through the guiding effect of the cross-shaped grooves 36 and the slide rail bracket 381, the cutting blade 33 can be adjusted to multiple angles to meet different cutting requirements. Once the cutting blade 33 is adjusted to the preset cutting position, the fixing ring 383, which is slidably connected to the inner wall of the top annular opening 382 on the outer wall of the blade holder 31, is rotated. The fixing ring 383 and the slide rail bracket 381 lock the position of the cutting blade 33, preventing it from moving along the grooves 36 during the cutting process and ensuring accurate cutting angles. After the cutting preparation is completed, the cutting operation is started. The push block 34 is operated. Since the push block 34 is fixedly connected to the top left side of the blade sliding plate 2, pushing the push block 34 can move the blade sliding plate 2 inside the base 1. During the movement of the blade sliding plate 2, the two sliders 371 fixedly connected to its bottom slide along the two locking grooves 372 opened at the bottom of the blade holder 31. The sliders 371 and the locking grooves 372 limit the movement trajectory and range of the blade sliding plate 2, preventing the blade sliding plate 2 from deviating during movement and ensuring that the blade sliding plate 2 can move stably along the preset path. As the blade sliding plate 2 moves, its top... The blade stage 31, which is fixedly connected to the base, moves synchronously, thereby driving the cutting blade 33, which is slidably connected to the top of the blade stage 31 via the slide rail bracket 381, to move. During the movement of the cutting blade 33, the position of the cutting blade 33 is locked by the fixing ring 383 and the slide rail bracket 381, which fixes the position of the cutting blade 33 and prevents the cutting blade 33 from becoming loose or shifting during movement and cutting, ensuring that the cutting blade 33 can maintain a stable cutting state. When the cutting blade 33 moves into the cutting chamber 32 opened on the rear side of the base 1 and comes into contact with the optical fiber to be cut, since the cutting blade 33 is made of diamond material, it can smoothly come into contact with the optical fiber and perform cutting. During the cutting process, fiber optic waste is generated. This waste falls into the fiber collection box 35 fixedly connected to the rear of the cutting chamber 32 under the action of gravity. The fiber collection box 35 collects the fiber optic waste, preventing it from scattering and affecting equipment operation and keeping the working environment clean. Thus, the entire process of multi-core fiber cutting is completed, from fiber fixing to cutting and waste collection. Throughout the process, the precise combination of each component ensures the stability of fiber fixing, the accuracy of the cutting angle and the efficiency of the cutting operation, and the orderly collection of waste, meeting the operational requirements of multi-core fiber cutting.
