Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of optical fiber corrosion equipment, in particular to an optical fiber segmented corrosion device. Background Art
[0002] The cross-sectional structure of common optical fiber is generally divided into three layers: core layer, cladding layer, and coating layer. The core layer and cladding layer are both made of silicon, but the core layer is doped with rare earth elements with high atomic number, i.e., high refractive index, so that the optical refractive index of the core layer is higher than that of the cladding layer, thereby realizing total internal reflection of light at the interface between the core layer and the cladding layer, and achieving the purpose of light beam transmission; the coating layer is generally made of resin material, which is used to protect the optical fiber made of quartz material, enhance the tensile strength and environmental tolerance of the optical fiber, etc. The so-called corroded optical fiber means that the quartz cladding of the optical fiber is corroded with a strong acid solution such as hydrofluoric acid after the coating layer of the optical fiber is stripped off first, so as to reduce the outer diameter of the quartz cladding of the finished optical fiber, thereby achieving the purpose required by some special experiments. The existing methods and devices for corroding optical fibers by soaking in hydrofluoric acid solution can generally only achieve one-end corrosion or middle-section corrosion, that is, stripping the coating layer of one end of an optical fiber and soaking it in hydrofluoric acid solution, so as to achieve the purpose of corroding this end, or stripping the coating layer of a middle section of an optical fiber and soaking it in hydrofluoric acid solution, so as to achieve the purpose of corroding the middle section of the optical fiber. Currently, there is no device that can achieve segmented corrosion on an optical fiber and can control different corrosion degrees in different segments. Utility Model Content

[0026] Combine the following Figure 1-Figure 4 The optical fiber segmentation corrosion device 10 of the present invention is described.
[0027] In view of the fact that the traditional technology has the problem that the fiber segment etching operation is difficult and the etching effect is poor. In order to solve the above problems, please refer to Figure 1-Figure 2 The utility model provides an optical fiber segmented etching device 10, including a base 1, on which a plurality of etching grooves 13 are opened, each etching groove 13 is arranged in sequence along a first direction, each etching groove 13 is used to respectively accommodate a etching solution, and each etching groove 13 arranged in sequence along the first direction is used to segmentally etch an optical fiber.
[0028] There are many ways to set the etching grooves 13. In the first embodiment, the etching grooves 13 arranged in sequence along the first direction are arranged at equal intervals. In this way, by selecting different etching grooves 13 to contain the etching solution, the optical fiber can be etched in sections, at the ends, or in the middle. In the second embodiment, the etching grooves 13 arranged in sequence along the first direction are arranged continuously. In this way, when each etching groove 13 contains the etching solution, the optical fiber can be etched in the entire section, when some of the continuous etching grooves 13 contain the etching solution, the optical fiber can be etched in the middle or at the ends, and when several of the discontinuous etching grooves 13 contain the etching solution, the optical fiber can be etched in sections.
[0029] Specifically, in the embodiment provided by the utility model, a through groove 11 extending along the first direction is provided on the base 1, and a plurality of partitions 12 are provided in the through groove 11 to divide the through groove 11 into a plurality of corrosion grooves 13, so that each corrosion groove 13 is continuously arranged, so that the device has the effects of whole-section corrosion, end corrosion, middle corrosion and segmented corrosion, and significantly improves the corrosion efficiency of the optical fiber. In addition, the corrosion groove 13 contains acid, which reduces the amount of acid used, helps to save economic costs, and further improves safety.
[0030] In order to be able to corrode multiple optical fibers at the same time and improve the efficiency of optical fiber corrosion, in the technical solution provided by the utility model, a plurality of through grooves 11 are provided on the base 1, and each through groove 11 is arranged side by side in sequence along the second direction, and the first direction and the second direction are arranged crosswise. By arranging a plurality of through grooves 11 side by side, each through groove 11 can be used to corrode an optical fiber, so that the optical fibers can be corroded at the same time, thereby improving work efficiency. Furthermore, the upper end surface of the partition 12 is provided with a C-shaped groove 14, and the C-shaped groove 14 can be used to clamp and fix the optical fiber, which is convenient for technicians to position and operate the optical fiber, and also prevents the optical fiber from moving during corrosion, thereby improving safety effects.
[0031] It should be noted that the optical fiber needs to be immersed in the corrosive solution in the corrosion groove 13 for corrosion, so the bottom height of each C-shaped groove 14 is greater than the bottom height of the corresponding corrosion groove 13, and less than the slot height of the corresponding corrosion groove 13, so that the optical fiber can be completely immersed in the corrosive solution, thereby improving the corrosion effect. The height of the partition 12 can be set to be level with the slot of the through groove 11, so that the groove depth of the C-shaped groove 14 is deeper and needs to be able to accommodate the entire optical fiber. When the height of the partition 12 is lower than the slot of the through groove 11, the groove depth of the C-shaped groove 14 can be set shallower, and it is only necessary to clamp the optical fiber and ensure that the upper wall surface of the optical fiber does not exceed the slot height of the through groove 11 when it is placed. The utility model does not limit this. In order to ensure the stable fixing effect of the optical fiber, the groove diameters of each C-shaped groove 14 on each through groove 11 are set to be the same.
[0032] Furthermore, in order to adapt to the corrosion of optical fibers of different sizes, in the technical solution provided by the present invention, the groove diameters of each C-groove 14 on different through grooves 11 are set differently, so that the device can simultaneously corrode optical fibers of different sizes, thereby improving the adaptability of the device.
[0033] In order to prevent the corrosive solution in the through groove 11 from overflowing and affecting safety, a return groove 15 is opened on the base. The return groove 15 is arranged around the through groove 11. The return groove 15 can receive the corrosive solution overflowing from the through groove 11, which improves safety on the one hand and facilitates the recycling of the solution on the other hand.
[0034] Specifically, in the technical solution provided by the utility model, the first direction extends along the length direction of the base 1, the second direction extends along the width direction of the base 1, and the first direction and the second direction are arranged perpendicular to each other. The first direction and the second direction may also be selected in other directions, and the utility model does not limit this. In order to facilitate the movement of the base 1, two buckle-pull steps are provided on the side of the base 1 away from the corrosion groove 13, and the base 1 can be moved by buckling the buckle-pull steps with both hands. Of course, a handle or other parts that facilitate movement can also be provided on the base 1.
[0035] See also Figure 3-Figure 4 , the utility model will provide two specific embodiments of optical fiber corrosion:
[0036] 1. Place an optical fiber to be corroded on the first row of through grooves 11, drip hydrofluoric acid into the first, third, fifth, seventh, and ninth corrosion grooves 13 in the first row, soak and corrode for a period of time, and then use a plastic dropper to suck out the hydrofluoric acid. This achieves the purpose of corroding the optical fiber in sections. The optical fiber corrosion results can be shown as follows: Figure 3 shown.
[0037] 2. Place an optical fiber to be corroded on the first row of through grooves 11, and drip hydrofluoric acid into the 1st to 9th corrosion grooves 13 in the first row. To control the degree of corrosion, the hydrofluoric acid should be sucked out in chronological order. The hydrofluoric acid in the first corrosion groove 13 should be sucked out first, and the hydrofluoric acid in the second corrosion groove 13 should be sucked out after a certain time interval. And so on, finally the hydrofluoric acid in the ninth corrosion groove 13 should be sucked out, and finally the purpose of segmented corrosion and controlling the degree of corrosion in different segments is achieved. The optical fiber corrosion result can be shown as follows: Figure 4 shown.
[0038] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the utility model, rather than to limit it. Although the utility model has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the aforementioned embodiments, or make equivalent replacements for some of the technical features therein.
