Description

Technical Field

[0001] The present invention relates to the field of optical fiber processing technology, and in particular to an integrated optical fiber fusion cutting and splicing device based on intelligent closed-loop feedback, which can realize automation and high-precision control of optical fiber cutting and splicing. Background Art

[0002] In fields such as fiber optic communications and fiber optic sensing, fiber splicing and cutting are critical operations. Traditional fiber optic cutting and splicing equipment typically operates independently. During actual operation, operators are required to transfer the cut fiber to the splicing equipment. This not only increases the complexity of the operation process and reduces work efficiency, but also easily causes contamination or damage to the fiber end face during the transfer process, affecting the quality of the fiber splice.

[0003] Meanwhile, while some existing fiber fusion splicing equipment has certain automation capabilities, it lacks an effective closed-loop feedback mechanism. During the splicing process, it's impossible to accurately monitor and adjust splicing parameters in real time, making it difficult to ensure consistent splicing quality across different types and specifications of optical fibers. This can easily lead to problems like high splice loss and low joint strength, limiting the development of fiber fusion splicing technology in more high-precision applications. Summary of the Invention

[0004] The purpose of the present invention is to provide an integrated optical fiber fusion cutting and splicing device based on intelligent closed-loop feedback, which integrates the optical fiber cutting and splicing functions into one, simplifies the operation process and improves work efficiency; through the intelligent closed-loop feedback system, the splicing parameters are monitored and adjusted in real time, the quality and consistency of optical fiber splicing are improved, and the high-precision requirements of optical fiber splicing in different application scenarios are met.

[0005] Technical Solution An integrated optical fiber fusion splicing and cutting device based on intelligent closed-loop feedback comprises a cutting unit, a fusion splicing unit, an intelligent closed-loop feedback system and a control unit.

[0006] The cutting unit includes a fiber fixture, a cutting head, and a cutting drive mechanism. The fiber fixture is used to secure the optical fiber to be processed. It utilizes an elastic clamping structure that automatically adjusts the clamping force according to the fiber's diameter, ensuring the fiber remains stable and stable during the cutting process. The cutting head is made of diamond material, boasting high hardness and a sharp edge, enabling high-precision fiber cutting. The cutting drive mechanism is connected to the cutting head and can drive it along a preset trajectory to complete the fiber cutting operation. The cutting drive mechanism utilizes a high-precision linear motor to ensure the accuracy and stability of the cutting head's movement.

[0007] The fusion splicing unit consists of an electrode holder, electrodes, and a splicing chamber. The holder is equipped with two opposing electrodes that generate a high-temperature arc, melting and splicing the cut fiber ends. The splicing chamber is a closed space equipped with an inert gas shield. This device allows the chamber to be filled with inert gas during the splicing process, preventing oxidation of the fiber ends at high temperatures and improving splice quality.

[0008] The intelligent closed-loop feedback system includes an image acquisition module, a parameter monitoring module, and a data processing module. The image acquisition module uses a high-resolution industrial camera installed inside the fusion chamber. It can collect real-time image information during the fiber fusion process, including the alignment of the fiber end faces, morphological changes in the fusion area, etc. The parameter monitoring module is used to monitor various parameters during the fusion process in real time, such as arc current, arc voltage, fusion time, fusion temperature, etc. This module uses high-precision sensors to ensure the accuracy of parameter monitoring. The data processing module is connected to the image acquisition module and the parameter monitoring module. It can analyze and process the collected image information and parameter data, judge the quality of the fiber fusion through a preset algorithm model, and compare it with the set standard parameters. If there is a deviation, the corresponding adjustment instruction is generated.

[0009] The control unit is connected to the cutting unit, welding unit, and intelligent closed-loop feedback system. It receives adjustment commands generated by the data processing module of the intelligent closed-loop feedback system and controls the operating status of the cutting unit and welding unit. Specifically, when the control unit receives a command to adjust the arc current, it can adjust the power supply to the electrodes in the welding unit to change the arc current. When it receives a command to adjust the position of the cutting head, it can control the cutting drive mechanism to adjust the position of the cutting head to meet different cutting requirements.

[0010] Beneficial effects Integrated Design: This device integrates fiber cleaving and splicing functions, reducing the need to transfer fibers between devices, streamlining operations, and significantly improving efficiency. It also avoids end-face contamination and damage that can occur during fiber transfer, ensuring high-quality splicing.

[0011] Intelligent Closed-Loop Feedback: The intelligent closed-loop feedback system collects real-time image information and various parameter data during the fiber splicing process, analyzes, processes, and compares them. This system can promptly identify problems during the splicing process and generate adjustment instructions, enabling dynamic adjustment of splicing parameters. This effectively improves the quality and consistency of fiber splicing, reduces splice losses, and enhances joint strength. The system is suitable for splicing different types and specifications of optical fibers, expanding the device's application range.

[0012] High-precision control: The cutting unit uses a high-precision linear motor to drive the cutting head. The fusion splicing unit generates a stable arc by precisely controlling the working parameters of the electrode. Combined with the real-time monitoring and adjustment of the intelligent closed-loop feedback system, high-precision control of the optical fiber cutting and fusion splicing processes is achieved, meeting the needs of high-precision optical fiber processing in fields such as optical fiber communication and optical fiber sensing. BRIEF DESCRIPTION OF THE DRAWINGS

[0014] 1. Cutting operation The optical fiber to be processed is placed in the fiber fixture of the cutting unit. The elastic clamp automatically clamps the fiber according to its diameter. The control unit activates the cutting drive mechanism, and the high-precision linear motor drives the cutting head along the preset cutting trajectory to cut the fiber. During the cutting process, if the image acquisition module of the intelligent closed-loop feedback system detects a shift in the fiber's position, the data processing module generates an adjustment command. Upon receiving the command, the control unit adjusts the cutting drive mechanism to realign the cutting head with the fiber, ensuring accurate cutting.

[0015] 2. Welding operation After the cutting is completed, the control unit automatically transfers the cut optical fiber to the fusion splicing chamber of the fusion splicing unit. The electrodes on the electrode holder generate a high-temperature arc under the action of the control unit, and at the same time, the inert gas protection device fills the fusion splicing chamber with inert gas. The image acquisition module collects images of the optical fiber fusion splicing process in real time, and the parameter monitoring module monitors parameters such as arc current, voltage, fusion time and temperature in real time. The data processing module analyzes the collected information. If it is found that the optical fiber end face is not completely aligned or the morphology of the fusion splicing area is abnormal, and there is a deviation between the fusion splicing parameters and the set standards, it will generate corresponding adjustment instructions, such as adjusting the electrode spacing to change the arc shape, adjusting the power supply to adjust the arc current, etc. After receiving the instructions, the control unit will promptly adjust the working status of the fusion splicing unit to ensure the quality of optical fiber fusion splicing.

Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
