[0041] Embodiment: The present embodiment discloses an optical fiber cutting device, which can realize batch cutting of optical fibers, thereby improving cutting efficiency while ensuring cutting quality, and refers to Figure 1 , comprising:

[0042] a base 1 having a cutting work area; the cutting work area is used to make the optical fiber located thereon be cut;

[0043] A guide plate 2 (see Figure 2 ) is arranged on the base 1, and a plurality of guide grooves 21 for guiding the arrangement of the optical fibers are arranged on the guide plate 2.

[0044] An optical fiber positioning member 3 is arranged for limiting the optical fibers in the cutting working area.

[0045] A cutting knife assembly 4 (see Figure 3 ) is arranged, which includes a support member 41 and a cutting knife 42 arranged at the end of the support member 41.

[0046] The support member 41 is slidably connected to the base 1 along the cutting direction, and drives the cutting knife 42 to cut the optical fibers.

[0047] In the embodiment, the arrangement of the optical fibers is guided by the guide grooves 21, and the optical fibers are fixed in the cutting working area (such as Figure 4 ) on the base 1 by cooperating with the optical fiber positioning member 3, and then the cutting knife 42 is moved along the base 1 to cut the optical fibers; the fixing of the optical fibers and the movement of the cutting knife 42 can achieve better cutting quality and reduce the risk of cutting damage caused by the movement of the optical fibers during cutting. Further, a plurality of guide grooves 21 are arranged, and a plurality of optical fibers can be arranged at the same time, thereby realizing batch cutting of the optical fibers.

[0048] Based on the above, the cutting knife is perpendicular to the optical fibers above for cutting. The guide plate 2 guides the arrangement of the optical fibers on the base 1, and the cutting knife 42 is moved along the base 1 to achieve cutting, so the guide plate 2 can control the relative position of the cutting knife 42 and the optical fibers, such as direction, distance, etc. In the embodiment, a plurality of guide grooves 21 with a size capable of accommodating only a single optical fiber are uniformly arranged on the guide plate 2, thereby achieving accurate positioning of each optical fiber, and the corresponding size of the guide grooves 21 can be arranged according to different specifications of the optical fibers, such as special angle requirements for the end face notch of the optical fiber (such as an 8° inclination angle required for communication optical fibers), and the angle of the corresponding guide grooves 21 can also be selected and configured.

[0049] Therefore, in a preferred embodiment, referring to Figure 1 , Figure 2 or Figure 4 , the optical fiber cutting device is configured with more than one guide plate 2, each of the guide plates 2 is provided with a plurality of parallel guide grooves 21, and the guide grooves 21 form a predetermined included angle with the cutting direction; it can be understood that the cutting knife 42 is moved along the base 1, so the cutting direction is the direction of the cutting knife 42 advancing (sliding), and different guide plates 2 can have guide grooves 21 with different sizes, inclination directions, and inclination angles; for the convenience of operation, each guide plate 2 is detachably connected to the base 1, so that different guide plates 2 can be adapted according to different optical fibers.

[0050] Based on the above, as an option, the guide grooves 21 can be distributed at an angle on the guide plate 2, so that the guide grooves 21 form a preset included angle with the cutting direction, and the corresponding guide plate 2 can be selected according to the optical fiber cutting requirements; further, as an option, the guide plate 2 can be rotatably connected to the base 1, so that the guide grooves 21 form a preset included angle with the cutting direction; that is, by rotating the guide plate 2 to control the relative position of the cutting knife 42 and the optical fiber; or, further, as an option, the cutting knife assembly 4 is rotatably connected to the cutting work area, so that the guide grooves 21 form a preset included angle with the cutting direction, and specifically the cutting knife assembly 4 can be rotatably connected to the base 1 to realize the rotation connection of the cutting work area, that is, by rotating the cutting knife 42 to control the relative position of the optical fiber, so as to cut the optical fiber at a preset included angle (direction).

[0051] The rotation of the above-mentioned guide grooves 21, guide plates 2 or cutting knife assemblies 4 is used to control the relative position of the cutting knife 42 and the optical fiber, so that the optical fiber is cut at a preset direction / angle. Based on the above setting, it is convenient to replace / adjust, so that the optical fiber is arranged in order and regularly on the guide plate 2, which is convenient for subsequent batch cutting, and the guide grooves 21 can limit the cutting angle of each optical fiber at the same time to adapt to different optical fiber cutting requirements. It can be understood that the guide grooves 21 in the embodiment are parallel, and in fact the guide grooves 21 can also be arranged at different angles on a guide plate 2.

[0052] In the embodiment, the above-mentioned support 41 includes a bracket 411, and the cutting knife 42 is rotatably connected to the bracket 411; the support 41 needs to be slidably connected to the base 1, as an example, the support 41 further includes a sliding block 412 connected to the bracket 411 away from the cutting knife 42; the base 1 is provided with a sliding groove 11 matched with the sliding block 412; the sliding groove 11 extends towards the cutting work area, and the side away from the cutting work area extends out of the base 1; thus the bracket 411 is slidably connected to the sliding groove 11 through the sliding block 412, the sliding block 412 can also slide out of the sliding groove 11 to realize a structure convenient for disassembly, and the bracket 411 and the base 1 can be separated, so that the optical fiber cutting device is more convenient and flexible whether in daily maintenance, component replacement or assembly adjustment for different use scenarios, thereby improving the practicality and adaptability of the whole device.

[0053] Further, as an optional design, the base 1 is connected with a limiting plate 13 arranged along the sliding groove 11 on at least one side of the sliding groove 11; the limiting plate 13 is partially connected with the base 1 and partially bent perpendicularly to the base 1, i.e. forms a side wall extending out of the base 1 and arranged along the sliding groove 11 on at least one side of the sliding groove 11, to give certain support and guidance to the sliding block 412, reduce the risk of disengagement of the sliding block 412 from the sliding groove 11, facilitate the assembly of the support 411 and the base 1, and improve the safety during use.

[0054] It can be understood that other existing structures capable of achieving sliding connection can also be used to achieve the sliding connection between the support 41 and the base 1.

[0055] In the embodiment, the cutting knife 42 is rotationally connected to the end of the support 411 and can extend above the optical fiber in the cutting work area, i.e. the cutting knife 42 cuts perpendicularly to the optical fiber above in the sliding direction, so that the end surface of the cut optical fiber is perpendicular / smooth and flat, improving the cutting quality; the cutting knife 42 can be circular and the middle part is connected to the support by a bolt to achieve rotational cutting; the cutting edge of the cutting knife 42 can be adjusted in rotation according to the wear condition, improving the service life of the cutting knife 42. It can be understood that in addition to the direction of the cutting knife 42, the pressure of the optical fiber cutting knife 42 has a key influence on the cutting quality of the optical fiber; too small pressure will cause the optical fiber to be not cut, and too large pressure will easily cause the deformation of the cutting surface of the optical fiber. Therefore, an adjustable pressure applying member is arranged on the support 411, which applies adjustable pressure to the cutting knife 42, so that the cutting knife 42 cuts the optical fiber with a preset cutting force. The pressure of the cutting knife 42 in cutting the optical fiber is accurately adjusted by the adjustable pressure applying member, thereby meeting different cutting requirements.

[0056] Specifically, in a preferred embodiment, referring to Figure 1 , Figure 3 or Figure 4 , the adjustable pressure applying member includes at least one counterweight 51 movably connected to the support 411, to apply adjustable pressure to the cutting knife 42 by moving the position of the counterweight 51 on the support 411, i.e. by adjusting the position of the counterweight 51; and / or, to apply adjustable pressure to the cutting knife 42 by adjusting the weight of the counterweight 51, i.e. by adjusting the weight of the counterweight 51; the above two adjustment methods can be applied or simultaneously, and as an optional design, an adjustment scale can be arranged on the support 411, the counterweight 51 is slid to a suitable scale position and fixed, to accurately adjust; for the same batch of optical fibers to be cut, the counterweight 51 only needs to be adjusted and fixed during the first cutting, and can be used for repeated cutting.

[0057] In another preferred embodiment, referring to Figure 5The adjustable pressure applying member can further include an elastic assembly 52. The elastic assembly 52 has an elastically deformed part that releases pressure in the direction of applying pressure to the cutting knife 42, so as to apply adjustable pressure to the cutting knife 42 by changing the degree of deformation of the elastically deformed part. Specifically, the elastically deformed part can include a spring 522 or an air bag (not shown in the figure), and the elastic assembly 52 includes, for example, an adjusting nut 521, the spring 522, a guide column 523, and a cutting knife fixing block 524. One side of the cutting knife fixing block 524 is connected to the support 411 through the guide column 523, and the other side is connected to the cutting knife 42. The adjusting nut 521 is located on the support 411 away from the cutting knife fixing block 524. One end of the spring 522 is connected to the adjusting nut 521, and the other end is connected to the cutting knife fixing block 524. By rotating the adjusting nut 521, the spring 522 is compressed, and then the cutting knife fixing block 524 is pressed, so as to adjust the pressure applied to the cutting knife 42.

[0058] In the embodiment, as described above, referring to Figure 1 or Figure 4 , the plurality of optical fibers can be arranged in order at one time by the guiding plate 2, and are quickly fixed by cooperating with the optical fiber positioning member 3. Compared with the traditional single optical fiber cutting mode, the efficiency of batch optical fiber cutting is greatly improved, and the labor and time cost is saved. Specifically, the optical fiber positioning member 3 includes a pressing plate 31, one end of which is rotatably connected to the base 1, and the other end is detachably connected to the base 1, so as to cover the optical fibers on the cutting work area. The optical fibers are limited between the pressing plate 31 and the base 1. The pressing plate 31 can completely cover the cutting work area, or at least partially cover the cutting work area. The pressing plate 31 is further provided with a cutting groove 32, and the cutting knife 42 is accommodated in the cutting groove 32 to cut the optical fibers.

[0059] In the embodiment, in order to improve the stability of the connection between the pressing plate 31 and the base 1 and further reduce the risk of movement of the optical fibers during cutting, a connecting member is further provided on the side of the pressing plate 31 away from the rotating connection with the base 1. Specifically, the connecting member includes a first magnetic attraction part 14 provided on the side of the pressing plate 31 away from the rotating connection with the base 1. The base 1 is provided with a second magnetic attraction part 34 cooperating with the first magnetic attraction part 14. The optical fibers are tightly limited between the pressing plate 31 and the base 1 by magnetic attraction.

[0060] Further, in order to reduce the risk of fiber being limited between the pressing plate 31 and the base 1 and its surface being damaged by friction with the pressing plate 31 and the base 1, a first protective pad 12 is arranged on the base 1 at the cutting work area; a second protective pad 33 corresponding to the first protective pad 12 is arranged on the side of the pressing plate 31 facing the cutting work area, and the first protective pad 12 and the second protective pad 33 can be silica gel, rubber or other structures having a buffering function (preferably with a hardness of about Shore 70).

[0061] Based on the above, the fiber is firmly and gently fixed by the magnet adsorption of the pressing plate 31 and the base 1 and the soft first protective pad 12 and the second protective pad 33, effectively reducing the shaking and displacement of the fiber during cutting, and improving the cutting precision and quality.

[0062] Specifically, as an example, the pressing plate 31 can include a plate body (not marked in the figure) covering the cutting work area and a rotating part (not marked in the figure) hinged to the pressing plate 31; the rotating part is vertically connected to one side of the plate body; the rotating part is provided with a rotating pin (not shown in the figure, forming a hinge structure) connected to the side wall of the base 1; when the pressing plate 31 rotates to completely cover the cutting work area, the plate body forms a region for containing the fiber relative to the base 1 in parallel; the plate body further extends to form a hand holding part (not shown in the figure) on the side away from the rotating part, so as to facilitate the rotation of the pressing plate 31, thereby realizing the opening and closing of the fiber positioning member 3, and facilitating the replacement of the fiber. When the pressing plate 31 is rotated to be horizontal with the base 1, the pressing plate 31 is clamped on the base 1 due to the magnetic force of the magnet. At this time, the first protective pad 12 on the base 1 and the second protective pad 33 on the pressing plate 31 clamp the fiber, which plays a role in fixing the fiber and prepares for cutting the fiber.

[0063] It can be understood that the above-mentioned pressing plate structure is only an example, and other structures capable of realizing fiber positioning can also be used.

[0064] Specifically, the use process is as follows: as shown in Figure 1 the figure, according to the fiber, a suitable guide plate 2 is selected and assembled, the user lifts the pressing plate 31 to the vertical state, places a certain amount of fiber on the fiber guide plate 2, one fiber is located in one guide groove 21, and the fibers are arranged uniformly on the guide plate 2, then the pressing plate 31 is turned over and clamped through the first magnetic attraction part 14 and the second magnetic attraction part 34, then the cutting knife assembly 4 is located in the sliding groove 11 on the base 1 through the bottom sliding block 412 of the cutting knife assembly 4, the direction of the cutting knife 42 is adjusted, the counterweight is adjusted to the appropriate scale or the spring 522 is adjusted to the appropriate compression degree, then the cutting knife assembly 4 is slowly pushed to move on the base 1, at this time the cutting knife 42 slides through the fiber after passing through the cutting groove 32 on the pressing plate 31 to cut the fiber.

[0065] Based on the above, the optical fiber cutting device provided by the embodiment can arrange multiple optical fibers in order at one time, realize fast fixing by cooperating with the pressing plate 31, and realize batch optical fiber cutting operation; the guide plate 2 can be configured in different directions and sizes, the cutting knife 42 is provided with an adjustable pressure applying part, the pressure of the cutting knife 42 when cutting the optical fiber can be simply and accurately adjusted, thereby adapting to the cutting requirements of optical fibers with different materials and specifications; the optical fiber is firmly and gently fixed by using the magnet adsorption of the pressing plate 31 and the base 1 and the soft protective pad, the shaking and displacement of the optical fiber in the cutting process is effectively avoided, the cutting precision and quality are guaranteed, and the cutting efficiency is improved while the cutting effect is improved.

[0066] It should be noted that the embodiments of the present application have better implementation, and do not limit the present application in any form, and any skilled person in the art can change or modify the equivalent effective embodiments by using the disclosed technical content, as long as it does not deviate from the technical scheme of the present application, and any modification or equivalent change and modification of the above embodiments according to the technical essence of the present application still belongs to the scope of the technical scheme of the present application.
