Description

Technical Field

[0001] The present invention relates to the field of optical fiber technology, and in particular to a method for manufacturing a high-temperature resistant optical fiber and the optical fiber. Background Art

[0002] LDI refers to laser direct imaging, which is mainly used in the exposure process of PCB manufacturing technology and is an application technology of direct writing exposure. The working principle of LDI is to convert the designed circuit graphics into an image generation program of the spatial light modulator through computer CAM software. The laser beam passes through the spatial light modulator, and the generated image is projected onto the substrate coated with photosensitive material through the optical imaging system to complete the pattern exposure on the substrate. One end of the LDI optical fiber is connected to the laser generator and the other end is connected to the lens. During the energy transfer process, as the energy required to be transmitted by the equipment increases, the temperature of the existing LDI optical fiber rises due to the increase in energy, which causes the glue in the LDI optical fiber to melt at high temperature, resulting in the position deviation of the originally positioned optical fiber bundle, affecting the performance of the optical fiber. The optical fiber bundle may also be burned due to excessive temperature, and the lens may be burned. Summary of the invention

[0003] The purpose of the present invention is to provide a method for manufacturing a high-temperature resistant optical fiber and an optical fiber in view of the defects and shortcomings of the prior art, which has the advantages of high temperature resistance of the optical fiber, avoiding the instability of energy transmission and equipment operation safety problems caused by the burning of the optical fiber during high energy transmission.

[0004] To achieve the above object, the technical solution adopted by the present invention is: a method for manufacturing a high temperature resistant optical fiber, characterized in that it comprises the following steps:

[0005] S1, exposing the optical fiber, stripping the outer surface coating of the optical fiber to expose the optical fiber;

[0006] S2, shaping, arranging and shaping the optical fibers stripped of coating to form an optical fiber bundle;

[0007] S3, shaping, shaping the optical fiber bundle through a positioner;

[0008] S4, solidification, adding molding medium to solidify the arrangement of each optical fiber bundle;

[0009] S5. Installation: insert the solidified optical fiber bundle into the metal shell;

[0010] S6, grinding;

[0011] S7. Remove the molding medium.

[0012] The present invention is further configured that in S7, an inorganic solution is used to clean the optical fiber to dissolve and volatilize the molding medium.

[0013] The present invention further provides that the molding medium is rosin.

[0014] The present invention is further arranged that the inorganic solution is alcohol.

[0015] To achieve the above object, another technical solution adopted by the present invention is: an optical fiber is prepared by the above-mentioned high temperature resistant optical fiber manufacturing method.

[0016] The present invention is further configured to include: a metal shell and an optical fiber bundle, wherein the metal shell is provided with a channel for inserting the optical fiber bundle.

[0017] After adopting the above technical scheme, the beneficial effect of the present invention is as follows: compared with the existing optical fiber, the temperature rises due to the increase of energy, which then causes the glue in the optical fiber to melt and cause the optical fiber bundle to burn, in the steps of the method for making high-temperature resistant optical fiber of the present invention, a molding medium is selected to solidify the arrangement state of the optical fiber bundle in the optical fiber, and the molding medium is removed after grinding, which can not only ensure that the arrangement state of the optical fiber bundle remains unchanged during grinding, but also remove the molding medium after grinding to avoid the situation where the optical fiber bundle is burned due to the molding medium being not resistant to high temperature; therefore, the present invention has the advantage of high temperature resistance of optical fiber, and ensures the stability of the energy transmission process and the safe operation of the equipment.

[0022] The present invention is further described in detail below in conjunction with the accompanying drawings.

[0023] This specific embodiment is only an explanation of the present invention, and it is not a limitation of the present invention. After reading this specification, those skilled in the art can make non-creative modifications to this embodiment as needed, but as long as it is within the scope of the claims of the present invention, it is protected by the patent law.

[0024] This embodiment relates to a method for manufacturing a high temperature resistant optical fiber. Figure 1, including the following steps:

[0025] S1, exposing the optical fiber, stripping the outer surface coating of the optical fiber to expose the optical fiber;

[0026] S2, shaping, arranging and shaping the optical fibers from which the coatings have been stripped to form an optical fiber bundle 200;

[0027] S3, shaping, shaping the optical fiber bundle 200 through a positioner;

[0028] S4, solidification, adding molding medium to solidify the arrangement state of each optical fiber bundle 200;

[0029] S5, installation, inserting the solidified optical fiber bundle 200 into the metal shell 100;

[0030] S6, grinding;

[0031] S7. Remove the molding medium.

[0032] In S1, the optical fiber is first fixed, and the optical fiber is fixed with an optical fiber clamp or other tools to prevent the optical fiber from sliding or shifting during the process of removing the outer coating of the optical fiber. In the process of removing the outer coating of the optical fiber, high-precision equipment can be used to assist in removing the outer coating. For example, laser stripping technology or ultrasonic-assisted stripping equipment is used to accurately control the stripping length and depth to avoid damaging the optical fiber core and maintain the cleanliness of the optical fiber surface. After removing the outer coating of the optical fiber, it is also necessary to check whether there is any residue on the surface of the optical fiber. If so, use dust-free paper or dust-free cotton dipped in anhydrous alcohol to gently wipe it clean. Note that it should be wiped gently in one direction when wiping, and avoid repeatedly using the same dust-free paper to prevent secondary contamination of the optical fiber. At the same time, it is also necessary to check whether the optical fiber is damaged to ensure that the optical fiber is intact, without cracks, and without bending. In S2, the optical fiber with the outer coating removed is arranged and shaped to form an optical fiber bundle 200. With the help of a machine vision system and a precision robotic arm, automatic recognition and precise arrangement of the optical fiber are achieved to ensure precise control of the optical fiber spacing, angle and position, and improve the overall accuracy of the optical fiber array.

[0033] In S3, a positioner is used to shape the optical fiber bundle 200 so that the size and shape of the shaped optical fiber bundle 200 are stable and not disordered. In this embodiment, a cleaning metal shell 100 can also be included between S4 and S5. The function of the cleaning metal shell 100 is to ensure that the surface inside the metal shell 100 is smooth, dry, and free of oil or other impurities, so as to avoid other oil or impurities affecting the bonding effect of the high-temperature resistant glue on the optical fiber bundle 200. In S6, the grinding is specifically to remove the outer layer material of the optical fiber through the contact between the grinding tool and the end face of the optical fiber, so that the end face of the optical fiber becomes smooth, the loss and reflection of the optical fiber are reduced, and the transmission efficiency and quality of the optical fiber are improved. After the optical fiber bundle 200 is ground in the above steps, the molding medium is removed, which well avoids the situation that the glue used to solidify the arrangement state of the optical fiber bundle 200 in the existing optical fiber is melted due to the increase of transmission energy and the rise of temperature during the use of the optical fiber, causing the optical fiber bundle to burn; and it can also ensure the arrangement state of the optical fiber bundle 200 during grinding.

[0034] In this embodiment, specifically, in S7, an inorganic solution is used to clean the optical fiber to dissolve and volatilize the molding medium, and the strong dissolving ability of the inorganic solution is utilized to effectively dissolve the molding medium. Compared with some organic solvents and glues, the inorganic solution is less likely to leave residues during the cleaning process. It can achieve the removal of the molding medium and will not affect the transmission performance of the optical fiber during the cleaning process.

[0035] Further, refer to Figure 1 , the molding medium is rosin. Rosin has higher plasticity and can be well attached to the optical fiber bundle 200 to solidify the arrangement state of each optical fiber bundle 200. Rosin has good insulation performance in addition, which can prevent the optical fiber from being affected by problems such as electromagnetic interference or short circuit. Meanwhile, rosin also has certain heat resistance, which can protect the optical fiber from the damage of high temperature environment to a certain extent, and prolong the service life of the optical fiber. In the present embodiment, the inorganic solution is alcohol, which utilizes the high solubility of rosin in alcohol and the volatile characteristics of alcohol, so as to reach the purpose of removing the molding medium and leaving no molding medium and inorganic solution in the optical fiber.

[0036] This embodiment also relates to an optical fiber, Figure 2 , which is prepared by the above-mentioned high temperature resistant optical fiber manufacturing method. The optical fiber has the characteristics of high temperature resistance and can maintain good working stability under high temperature conditions. Further, the optical fiber includes: a metal shell 100 and an optical fiber bundle 200, wherein the metal shell 100 is provided with a channel for the optical fiber bundle 200 to be placed. The material selection of the metal shell 100 can be selected from high temperature resistant materials with good performance such as tungsten-cobalt alloy, nickel-based alloy, cobalt-based alloy, inorganic ceramics, etc. The metal shell 100 is also reliable and dust-proof.

[0037] The advantages of the present invention are as follows: Unlike the prior art, the present invention does not need to use glue to solidify the shaped optical fiber bundle 200, thus avoiding the burning of the optical fiber caused by the melting of glue at high temperature. After the optical fiber bundle 200 is shaped, a molding medium is added to solidify the arrangement state of the optical fiber bundle 200, ensuring that the arrangement state of the optical fiber bundle 200 remains unchanged. After grinding, the molding medium is removed using an inorganic solution, so that the optical fiber has high temperature resistance, ensuring that the optical fiber maintains good performance under high temperature conditions, and protecting the stability of energy transmission and the safety of equipment operation.

[0038] The above is only used to illustrate the technical solution of the present invention rather than to limit it. Other modifications or equivalent substitutions made to the technical solution of the present invention by ordinary technicians in this field should be included in the scope of the claims of the present invention as long as they do not depart from the spirit and scope of the technical solution of the present invention.
