Abstract
Description
Technical Field
[0001] This utility model relates to the field of optical fiber production technology, specifically to an online optical fiber cutting and clamping device. Background Technology
[0002] Optical fiber, as an important transmission medium, plays a vital role in communications, medicine, industry, and other fields. With the continuous development of optical fiber technology, the requirements for fiber optic dicing quality are becoming increasingly stringent. Traditional fiber optic dicing methods often suffer from the following problems:
[0003] 1. The device is stationary, while the optical fiber is in motion during the cutting process. This relative motion causes the optical fiber to be under tension, which may break the optical fiber. The optical fiber may develop microcracks and surface defects due to the tension, affecting its transmission performance and service life.
[0004] 2. In existing fiber optic cleaving devices, the cleaving mechanism and clamping mechanism operate synchronously. When the clamping mechanism has not fully clamped the fiber, the cleaving mechanism has already started cutting, causing the fiber to spring back, which affects the cleaving accuracy and surface quality.
[0005] Therefore, it is necessary to provide an online fiber optic cutting and clamping device to solve the above-mentioned technical problems. Utility Model Content
[0006] The purpose of this invention is to provide an online optical fiber cutting and clamping device to solve the problem mentioned in the background art where, when the device is stationary, the relative motion during the optical fiber cutting process causes the optical fiber to be subjected to tensile force, which may lead to breakage. Simultaneously, the stress on the optical fiber may generate microcracks and surface defects, affecting transmission performance and lifespan. This invention provides a significantly different solution from existing technologies, addressing the problem of overly simplistic solutions.
[0007] To achieve the above objectives, this utility model provides the following technical solution: an online optical fiber cutting and clamping device, comprising a cutting and pressing mechanism, a clamping and pressing mechanism, and a cutting and guiding mechanism. The cutting and pressing mechanism includes a first pressing block installed inside a base groove, and a first vertical telescopic sleeve rod installed at the bottom of the first pressing block. A spring is provided inside the first vertical telescopic sleeve rod, and a first oil pipe is connected to one side of the first pressing block. The clamping and pressing mechanism includes a second pressing block installed inside a base groove, and a second vertical telescopic sleeve rod is provided at the bottom of the second pressing block. A second oil pipe is connected to one side of the second vertical telescopic sleeve rod.
[0008] In a further embodiment, a base is also included, a lead screw is connected inside the groove of the base, and a slider is threadedly connected to the outside of the lead screw. The two sides of the slider and the groove of the base form a sliding structure, and telescopic push rods are symmetrically arranged below the slider through the mounting groove.
[0009] In a further embodiment, the device also includes an electric telescopic sleeve rod, two of which are symmetrically installed on both sides of the inner wall of the U-shaped groove above the slider, and the telescopic ends of the electric telescopic sleeve rods are connected to clamping blocks, which are made of rubber.
[0010] In a further embodiment, the cutting guide mechanism includes a first transverse telescopic sleeve rod respectively disposed on one side of the two support portions, and a second transverse telescopic sleeve rod is disposed on the extension portion of the first transverse telescopic sleeve rod. A guide rod is installed on one side of the telescopic end of the first transverse telescopic sleeve rod. A blade and a blade holder are respectively connected to the extension ends of the two second transverse telescopic sleeve rods. A guide groove is opened on the inner wall of the rotating part of the second transverse telescopic sleeve rod. A guide component is connected to the outer side of the telescopic end of the second transverse telescopic sleeve rod. A torsion spring with telescopic function is disposed on the inner side of the second transverse telescopic sleeve rod.
[0011] In a further embodiment, the support is mounted on the base, and the support is connected through the first oil pipe, with the end of the first oil pipe communicating with the first transverse telescopic sleeve.
[0012] In a further embodiment, a clamping and winding mechanism is also included. The clamping and winding mechanism is mounted above the base via a connecting plate, and a telescopic cylinder is connected to the movable end of one side of the clamping and winding mechanism. The telescopic cylinder is connected to the end of the second oil pipe.
[0013] Compared with existing technologies, the beneficial effects of this utility model are:
[0014] This utility model features a cutting and extrusion mechanism, with the cutting and clamping mechanisms controlled independently to ensure that the optical fiber is fully clamped and cut simultaneously, preventing fiber springback. Compared with existing technologies, this improves cutting accuracy and surface quality. Furthermore, by cutting the optical fiber while it is in motion, this device avoids the tension caused by traditional static cutting devices, reducing the risk of fiber breakage and minimizing microcracks and surface defects, thereby improving the transmission performance and lifespan of the optical fiber.
[0015] 2. In this utility model, the main driving force comes from the movement of the slider, which drives the cutting and clamping extrusion mechanism and the clamping extrusion mechanism.

[0025] The technical solutions of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.
[0026] Please see Figure 1-8 The present invention provides an embodiment of an online optical fiber cutting and clamping device, the specific operation steps of which are as follows:
[0027] Please refer to the following carefully. Figure 1 and Figure 8 It includes an electric telescopic sleeve rod 4, two electric telescopic sleeve rods 4 are symmetrically installed on both sides of the inner wall of the U-shaped groove above the slider 3, and the telescopic end of the electric telescopic sleeve rod 4 is connected to a clamping block 5, which is made of rubber. Before cutting the optical fiber, the electric telescopic sleeve rod 4 is started by the control button. At this time, the two electric telescopic sleeve rods 4 simultaneously drive the corresponding clamping block 5 to clamp the optical fiber.
[0028] Please refer to the following carefully. Figure 1 The system includes a base 1, a lead screw 2 connected inside the groove of the base 1, and a slider 3 threadedly connected to the outside of the lead screw 2. The slider 3 and the groove of the base 1 form a sliding structure on both sides, and telescopic push rods 301 are symmetrically arranged below the slider 3 through the mounting groove. When the motor on one side of the base 1 is started, the lead screw 2 is driven to rotate, which drives the slider 3 and the telescopic push rods 301 to move in coordination with the groove on the inner side of the base 1. The telescopic push rods 301 are located below the slider 3, and the telescopic end of the telescopic push rods 301 is L-shaped.
[0029] Please refer to the following carefully. Figure 3 , Figure 5-8 The system comprises a cutting and extrusion mechanism 6, a clamping and extrusion mechanism 7, and a cutting and guiding mechanism 9. The cutting and extrusion mechanism 6 includes a first extrusion block 601 installed inside a groove in the base 1, with a first vertical telescopic sleeve 602 mounted at the bottom of the first extrusion block 601. A spring is provided inside the first vertical telescopic sleeve 602, and a first oil pipe 603 is connected to one side of the first extrusion block 601. The clamping and extrusion mechanism 7 includes a second extrusion block 701 installed inside a groove in the base 1, with a second vertical telescopic sleeve 702 at the bottom of the second extrusion block 701. A second oil pipe 703 is connected to one side of the second vertical telescopic sleeve 702. The cutting and guiding mechanism 9 includes a first horizontal telescopic sleeve 901 respectively disposed on one side of each of the two support parts 8. The extension of the transverse telescopic sleeve 901 is provided with a second transverse telescopic sleeve 902. A guide rod 901a is installed on one side of the telescopic end of the first transverse telescopic sleeve 901. The extension ends of the two second transverse telescopic sleeves 902 are respectively connected to the blade 903 and the blade holder 904. The inner wall of the rotating part of the second transverse telescopic sleeve 902 is provided with a guide groove 902b. The outer side of the telescopic end of the second transverse telescopic sleeve 902 is connected to the guide component 902a. The inner side of the second transverse telescopic sleeve 902 is provided with a torsion spring with telescopic function. The support part 8 is installed on the base 1. The support part 8 is connected to the first oil pipe 603 through the first oil pipe 603. The end of the first oil pipe 603 is connected to the first transverse telescopic sleeve 901.
[0030] When the telescopic push rod 301 moves above the first extrusion block 601, it can press down on the first extrusion block 601 in conjunction with the arc at one end of the first extrusion block 601. Then, the first vertical telescopic sleeve rod 602 retracts downward under the elastic action of the spring, so that the oil inside the first vertical telescopic sleeve rod 602 is squeezed to the inside of the first horizontal telescopic sleeve rod 901 through the first oil pipe 603, thereby driving the first horizontal telescopic sleeve rod 901 to extend. In conjunction with the spring, it presses the telescopic end of the second horizontal telescopic sleeve rod 902, so that the blades 903 and the blade holders 904 at the ends of the two second horizontal telescopic sleeve rods 902 can move relative to each other at the same time, thereby cutting the optical fiber during the clamping process.
[0031] When the two first transverse telescopic sleeves 901 extend relative to each other, the second transverse telescopic sleeve 902 can be rotated by the guide rod 901a on one end under the guidance of the guide groove 902b. The rotation of the second transverse telescopic sleeve 902 causes the guide rod 901a to flip. Under the action of the flipping of the guide rod 901a, the cut optical fiber end can be guided to the clamping groove in the middle of the clamping and winding mechanism 10. At this time, since the end of the telescopic push rod 301 is L-shaped, when the L-shaped telescopic push rod 301 moves, one end can not only press on the first extrusion block 601, but the other end can also press on the second extrusion block 701. Therefore, when the cut optical fiber end falls into the clamping groove in the clamping and winding mechanism 10, the optical fiber can be clamped on one hand, and the optical fiber end can be guided to fall into the clamping groove. At the same time, when the telescopic push rod 301 extrudes the second extrusion block 701, it can also extrude the second vertical telescopic sleeve 702 downward in conjunction with the internal spring.
[0032] Please refer to the following carefully. Figure 1-2 7-8, including a clamping and winding mechanism 10, which is mounted on the base 1 via a connecting plate, and a telescopic cylinder 11 is connected to the movable end of one side of the clamping and winding mechanism 10. The telescopic cylinder 11 is connected to the end of the second oil pipe 703. This allows the oil inside the second vertical telescopic sleeve 702 to be squeezed into the inside of the telescopic cylinder 11 through the second oil pipe 703, thereby causing the telescopic cylinder 11 to extend and push the movable end of the clamping and winding mechanism 10 to move, thereby clamping and winding the optical fiber. At the same time, the motor speed on one side of the clamping and winding mechanism 10 will correspondingly accelerate, which can tighten the loose parts of the cut optical fiber. This clamping and winding mechanism 10 is the prior art described in patent number CN209466635U, so it will not be described in detail here.
[0033] After the cut optical fiber is clamped, the motor drives the lead screw 2 to reverse, causing the slider 3 to return to the initial stage. At this time, the telescopic push rod 301 also moves. In order to prevent the telescopic push rod 301 from squeezing the second squeezing block 701 and the first squeezing block 601 when it retracts, the second squeezing block 701 and the first squeezing block 601 are set in a V-shape. Therefore, when the telescopic push rod 301 moves, its end can retract inward with the inclined edge of the second squeezing block 701 and the first squeezing block 601 until it returns to the initial position. The cutting guide mechanism 9 is reset and flipped to the initial state by the internal telescopic torsion spring.
[0034] Working principle: When an optical fiber is in motion, the existing cutting device is stationary. When cutting the fiber, a certain tensile force is applied, causing it to break. Furthermore, the fiber may develop microcracks, surface defects, and other problems due to the tensile force. The solution is as follows:
[0035] like Figure 1 As shown, before cutting the optical fiber, the electric telescopic sleeve 4 is activated by the control button. At this time, the two electric telescopic sleeves 4 simultaneously drive the corresponding clamping blocks 5 to clamp the optical fiber.
[0036] At the same time, the motor on one side of the base 1 drives the lead screw 2 to rotate, which drives the slider 3 and the telescopic push rod 301 to move in coordination with the groove on the inner side of the base 1. The telescopic push rod 301 is located below the slider 3, and the telescopic end of the telescopic push rod 301 is L-shaped.
[0037] like Figure 3 , Figure 5-8 As shown, when the two first transverse telescopic sleeves 901 extend relative to each other, the guide rod 901a on one end, guided by the guide groove 902b, can drive the second transverse telescopic sleeve 902 to rotate. The rotation of the second transverse telescopic sleeve 902 causes the guide rod 901a to flip. Under the action of the flipping of the guide rod 901a, the cut optical fiber end can be guided into the clamping groove in the middle of the clamping and winding mechanism 10. At this time, since the end of the telescopic push rod 301 is L-shaped, when the L-shaped telescopic push rod 301 moves, one end can not only press on the first extrusion block 601, but the other end can also press on the second extrusion block 701. Therefore, when the cut optical fiber end falls into the clamping groove in the clamping and winding mechanism 10, the optical fiber can be clamped on one hand, and the optical fiber end can be guided into the clamping groove on the other hand. At the same time, when the telescopic push rod 301 presses the second extrusion block 701, it can also press the second vertical telescopic sleeve 702 downward with the help of the internal spring. Figure 2As shown, the oil inside the second vertical telescopic sleeve 702 is squeezed into the inside of the telescopic cylinder 11 through the second oil pipe 703, thereby causing the telescopic cylinder 11 to extend and push the movable end of the clamping and winding mechanism 10 to move, thereby clamping and winding the optical fiber. At the same time, the motor speed on one side of the clamping and winding mechanism 10 will accelerate accordingly, so as to tighten the loose part of the cut optical fiber. The clamping and winding mechanism 10 is the prior art described in patent number CN209466635U, so it will not be described in detail here.
[0038] like Figure 7-8 As shown, after the cut optical fiber is clamped, the motor drives the lead screw 2 to reverse, causing the slider 3 to return to the initial stage. At this time, the telescopic push rod 301 also moves. In order to prevent the telescopic push rod 301 from squeezing the second squeezing block 701 and the first squeezing block 601 when it retracts, the second squeezing block 701 and the first squeezing block 601 are set in a V-shape. Therefore, when the telescopic push rod 301 moves, its end can retract inward with the inclined edge of the second squeezing block 701 and the first squeezing block 601 until it returns to the initial position. The cutting guide mechanism 9 is reset and flipped to the initial state by the internal telescopic torsion spring.
