Description

Technical Field

[0001] This invention relates to the field of optical fiber production technology, specifically to a method, apparatus, and storage medium for connecting an optical fiber preform to a tail tube. Background Technology

[0002] In recent years, with the development of optical fiber communication technology, higher demands have been placed on optical fiber production efficiency. As the diameter differences of optical fiber preforms have become increasingly significant, the requirements for the connection between the optical fiber preform and the pigtail have become more stringent. The connection between the optical fiber preform and the pigtail is a crucial step in the optical fiber manufacturing and optical fiber network installation process. The optical fiber preform is the core material for manufacturing optical fibers, typically made of high-purity glass and possessing uniform optical properties. The pigtail, in optical fiber network installation, usually refers to part of the optical fiber connector used to connect two optical fibers or an optical fiber to equipment.

[0003] During the splicing process of the optical fiber preform and the tail tube, the following technical problems may occur when the splicing rotation speed of the optical fiber preform and the tail tube changes:

[0004] 1) Variations in the docking rotation speed may affect the thermal stress distribution at the docking interface. During the docking process, the preform and tail tube are typically heated to soften the materials and promote fusion. Variations in rotation speed may lead to uneven heat distribution, resulting in thermal stress concentration or uneven distribution at the docking interface, which in turn affects the performance and dynamic stability of the optical fiber.

[0005] 2) The melting efficiency and uniformity of optical fiber preforms vary at different rotation speeds. Higher rotation speeds may improve melting efficiency but may also lead to uneven melting; lower rotation speeds may make the melting process more uniform but are less efficient. Optimizing the melting efficiency and uniformity of optical fiber preforms to ensure docking quality is a pressing technical problem that needs to be solved.

[0006] 3) Rotational speed variations affect the distribution and conduction of heat in the splicing area between the optical fiber preform and the tail tube. Excessive temperature can lead to material damage or performance changes. Ensuring the stability of the molten interface and effectively controlling its temperature to prevent material damage or performance degradation due to overheating, while ensuring the stability and reliability of the splicing process, is a pressing technical problem that needs to be solved.

[0007] 4) When docking at different speeds, operational interference and errors may increase, which can easily lead to docking quality accidents, such as broken rods, incomplete connections, and air lines. How to reduce the errors and interference caused by manual operation and improve the accuracy and consistency of docking is a technical problem that urgently needs to be solved. Summary of the Invention

[0008] To address the technical problems that arise when the rotational speed of the optical fiber preform and tail tube changes, such as uneven heat distribution at the docking interface, poor melting quality and efficiency, difficulty in achieving heat transfer and temperature control, and interference and errors from manual operation, this invention proposes a method, device, and storage medium for docking optical fiber preforms and tail tubes.

The PLC controller outputs the optimal cooling water flow rate data control command to the cooling water flow controller. The cooling water flow controller is used to control the actual cooling water flow rate to reach the optimal cooling water flow rate.

[0016] As a preferred technical solution, step S1 includes the following steps: using big data, digital twin technology, and design simulation platform to combine and summarize docking instance data under different parameter setting conditions, complete the standard parameter simulation output, and carry out simulation optimization and redesign based on actual application results to obtain the parameters under the optimal melting state when the optical fiber preform and tail tube are docked at different rotation speeds.

The optimal flow ratio of hydrogen and oxygen and / or the optimal flow rate of cooling water are collected to generate a dataset.

[0035] S2 acquires the actual docking speed data of optical fiber preform 1 and tail tube 2 in real time. Based on the acquired actual docking speed data of optical fiber preform 1 and tail tube 2, it automatically matches the optimal flow ratio of hydrogen and oxygen and / or the optimal flow rate of cooling water in the dataset, and controls the actual flow ratio of hydrogen and oxygen and / or the actual flow rate of cooling water to reach the optimal flow ratio of hydrogen and oxygen and / or the optimal flow rate of cooling water.

[0036] This invention proposes a method for docking optical fiber preforms and tail tubes, which ensures the uniformity of heat distribution at the docking interface, improves the melting quality and efficiency of the docking interface, automates heat transfer and temperature control, and solves technical problems such as interference and errors from manual operation.

[0037] Preferably, step S1 includes the following steps: using big data, digital twin technology, and design simulation platform to combine and summarize docking instance data under different parameter setting conditions, complete the standard parameter simulation output, and carry out simulation optimization and redesign based on actual application results to obtain the parameters under the optimal melting state at different rotation speeds of the optical fiber preform and tail tube docking, thereby continuously improving the rationality of the docking process parameter setting.

[0038] The parameters for the optimal molten state of the optical fiber preform and tail tube at different rotation speeds include: the dimensions of preform 1 and tail tube 2, the hydrogen and oxygen flow ratio, and the cooling water flow rate.

[0039] Preferably, in step S1, the optimal melting state of the optical fiber preform and the tail tube is monitored at different rotation speeds using a gas wire detector and an image monitor.

[0040] Preferably, in step S2, the optimal flow ratio of hydrogen and oxygen in the dataset is input into the PLC controller 9. The PLC controller 9 acquires the actual docking speed data of the optical fiber preform 1 and the tail tube 2 in real time, and automatically matches the optimal flow ratio of hydrogen and oxygen in the dataset. The PLC controller 9 outputs the optimal flow ratio of hydrogen and oxygen control command to the gas mass flow controller 3. The gas mass flow controller 3 is used to control the actual flow ratio of hydrogen and oxygen to achieve the optimal flow ratio of hydrogen and oxygen.

[0041] Preferably, in step S2, the optimal cooling water flow rate data in the dataset is input to the PLC controller 9. The PLC controller 9 acquires the actual docking speed data of the optical fiber preform and the tail tube in real time, and automatically matches the optimal cooling water flow rate data in the dataset. The PLC controller 9 outputs the optimal cooling water flow rate data control command to the cooling water flow controller 4. The cooling water flow controller 4 is used to control the actual cooling water flow rate ratio to achieve the optimal cooling water flow rate.

[0042] This invention provides a method for connecting an optical fiber preform to a tail tube, comprising the following steps:

[0043] The optimal melting state of the optical fiber preform 1 and tail tube 2 at the initial docking speed is monitored using a gas line detector (not shown) and an image monitor (not shown). The size parameters of the preform 1 and tail tube 2, the initial hydrogen and oxygen flow ratio, and the cooling water flow parameters are preset. Then, the docking speed of the optical fiber preform 1 and tail tube 2 is increased. As the docking speed of the optical fiber preform 1 and tail tube 2 increases, the optimal melting state of the optical fiber preform 1 and tail tube 2 after increasing the docking speed is monitored using a gas line detector (not shown) and an image monitor (not shown). The hydrogen and oxygen flow ratio and / or cooling water flow rate entering the docking equipment are adjusted to obtain the optimal hydrogen and oxygen flow ratio and / or optimal cooling water flow rate. The above steps are repeated to obtain data on the optimal hydrogen and oxygen flow ratio and / or optimal cooling water flow rate at different docking speeds to achieve the optimal melting state of the optical fiber preform 1 and tail tube 2. The data on the optimal hydrogen and oxygen flow ratio and / or optimal cooling water flow rate are collected to form a dataset, which is then input into the PLC controller 9.

[0044] The PLC controller 9 acquires the actual docking speed data of the optical fiber preform 1 and the tail tube 2 in real time, and automatically matches the optimal flow ratio of hydrogen and oxygen in the dataset. The PLC controller 9 outputs the optimal flow ratio control command of hydrogen and oxygen to the gas mass flow controller 3. The gas mass flow controller 3 is used to control the actual flow ratio of hydrogen and oxygen to achieve the optimal flow ratio of hydrogen and oxygen.

[0045] The PLC controller 9 acquires the actual docking speed data of the optical fiber preform 1 and the tail tube 2 in real time, and automatically matches the optimal cooling water flow data in the dataset. The PLC controller outputs the optimal cooling water flow data control command to the cooling water flow controller 4. The cooling water flow controller 4 is used to control the actual cooling water flow ratio to achieve the optimal cooling water flow.

[0046] To ensure the uniformity and stability of the fusion state of the optical fiber preform and the tail tube during the connection, thereby completing the quality control of the connection between the optical fiber preform and the tail tube.

[0047] like Figure 2 As shown, the present invention provides a fiber optic preform and tailpipe docking device, comprising: a lathe (not shown), the lathe (not shown) being used to collect and preset the optimal flow ratio of hydrogen and oxygen and / or the optimal flow data of cooling water in the dataset, the lathe (not shown) being electrically connected to a PLC controller 9, the PLC controller 9 being used to acquire the actual docking rotation speed data of the fiber optic preform 1 and the tailpipe 2 in real time, and the PLC controller 9 being electrically connected to a gas mass flow controller 3 and a cooling water flow controller 4 respectively;

[0048] Preferably, the gas mass flow controller 3 includes: a first gas mass flow controller 31, one end of the hydrogen conduit 5 is connected to the ignition nozzle 8, and the other end of the hydrogen conduit 5 is connected to the first gas mass flow controller 31.

[0049] Preferably, the gas mass flow controller 3 includes: a second gas mass flow controller 32, one end of the oxygen conduit 6 is connected to the ignition nozzle 8, and the other end of the oxygen conduit 6 is connected to the second gas mass flow controller 32.

[0050] Preferably, one end of the cooling water conduit 7 is connected to the ignition nozzle 8, and the other end of the cooling water conduit 7 is connected to the cooling water flow controller 4.

[0051] The lathe (not shown) collects and presets the optimal flow ratio of hydrogen and oxygen in the dataset and transmits it to the PLC controller 9. The PLC controller 9 is used to acquire the actual docking speed data of the optical fiber preform 1 and the tail tube 2 in real time, and automatically matches the optimal flow ratio of hydrogen and oxygen in the dataset. The PLC controller 9 outputs the optimal flow ratio control command of hydrogen and oxygen to the first gas mass flow controller 31. The first gas mass flow controller 31 is used to control the actual flow rate of hydrogen input into the hydrogen conduit 5 to the ignition nozzle 8 to achieve the optimal flow ratio of hydrogen and oxygen, so as to control the flame temperature and intensity of the flame acting by the ignition nozzle 8 at the interface between the optical fiber preform 1 and the tail tube 2.

[0052] The lathe (not shown) collects and presets the optimal flow ratio of hydrogen and oxygen in the dataset and transmits it to the PLC controller 9. The PLC controller 9 is used to acquire the actual docking speed data of the optical fiber preform 1 and the tail tube 2 in real time, and automatically matches the optimal flow ratio of hydrogen and oxygen in the dataset. The PLC controller 9 outputs the optimal flow ratio control command of hydrogen and oxygen to the second gas mass flow controller 32. The second gas mass flow controller 32 is used to control the actual flow rate of oxygen input into the oxygen conduit 6 to the ignition nozzle 8 to achieve the optimal flow ratio of hydrogen and oxygen, so as to control the flame temperature and intensity of the flame acting on the interface between the optical fiber preform 1 and the tail tube 2 by the ignition nozzle 8.

[0053] When the actual flow rate ratio of hydrogen to oxygen reaches the optimal ratio, sufficient heat is provided to melt the interface between the optical fiber preform and the tail tube, achieving high-quality docking. A hydrogen-to-oxygen ratio that is too low may result in insufficient flame temperature and incomplete melting; a ratio that is too high may generate excessively high temperatures, leading to material damage or unnecessary thermal stress. The optimal hydrogen-to-oxygen flow rate ratio helps maintain a stable combustion state, avoiding flame flickering or instability, which helps maintain the uniformity of the molten interface and the stability of the docking quality.

[0054] The lathe (not shown) collects and presets the optimal cooling water flow data in the dataset and transmits it to the PLC controller 9. The PLC controller 9 is used to acquire the actual docking speed data of the optical fiber preform 1 and the tail tube 2 in real time, and automatically matches the optimal cooling water flow data in the dataset. The PLC controller 9 outputs the optimal cooling water flow data control command to the cooling water flow controller 4. The cooling water flow controller 4 is used to control the actual flow rate of cooling water input to the ignition nozzle 8 in the cooling water conduit 7 to reach the optimal cooling water flow rate, so as to indirectly affect the temperature distribution in the docking area of ​​the optical fiber preform and the tail tube by affecting the temperature of the ignition nozzle 8.

[0055] Although cooling water does not directly participate in the melting process, controlling the cooling water flow rate can indirectly affect the temperature distribution in the area where the optical fiber preform and the tail tube are joined by influencing the temperature of the ignition nozzle. If the cooling water flow rate is insufficient, the ignition nozzle 8 may overheat, affecting the stability of the molten state; if the cooling water flow rate is too high, the ignition nozzle 8 may become too cold, affecting the stability of the flame and the joining efficiency. By controlling the actual flow rate of cooling water entering the ignition nozzle 8 from the cooling water conduit 7 to achieve the optimal flow rate, the above-mentioned technical problems can be avoided.
