Description

Technical Field

[0001] This application relates to the field of fiber optic sensor manufacturing technology, and in particular to an integrated system for automatic fiber optic cutting and splicing. Background Technology

[0002] Detection technology has always been a key technology for scientific development and progress. The high precision and high sensitivity of optical detection make it one of the most important methods in the current detection field. Among these, optical imaging technology has the widest application and attracts the most attention from research teams. Optical fibers, with their small size, strong anti-interference ability, and ability to achieve remote real-time imaging and monitoring, are widely used in communications and various other fields of detection.

[0003] In the field of detection, fiber optic interferometers and fiber optic sensors based on the interference principle are the most common. These optical devices are mainly manufactured by using fiber optic misalignment fusion splicing technology to splice optical interference cavities of different lengths into two fiber segments. However, this manufacturing technology is mainly used for laboratory research. The steps of misaligning and splicing two fibers, and cutting micron-sized optical interference cavities into the misaligned fibers, all require operators to spend a lot of time. The operation process is cumbersome and involves a large amount of manual work. Furthermore, there are certain operational errors in the manual cutting and splicing process, which seriously affect the standardization of the manufactured fiber optic misalignment fusion structure. This seriously affects the manufacturing efficiency of fiber optic misalignment fusion structures, which greatly limits the production and manufacturing of fiber optic interferometers and fiber optic sensors based on the interference principle, becoming the biggest obstacle to their industrialization. Summary of the Invention

[0004] The purpose of this application is to provide an integrated automatic fiber optic cutting and splicing system that can automate the manufacturing of fiber optic misalignment splicing structures and improve manufacturing efficiency.

[0005] To achieve the above objectives, this application provides the following solution:

[0006] In a first aspect, this application provides an integrated automatic fiber optic cleaving and splicing system, comprising: a computer module, a fusion splicing and cleaving module, and a first fiber optic control module and a second fiber optic control module located on both sides of the fusion splicing and cleaving module.

[0007] The first fiber optic control module is used to clamp one end of the initial fiber optic cable and, under the control of the computer module, move one end of the initial fiber optic cable axially.

[0008] The second fiber control module is used to simultaneously clamp one end of the misaligned fiber and one end of the fusion splice fiber, and under the control of the computer module, to move one end of the misaligned fiber and one end of the fusion splice fiber along the axial or radial direction; the clamped ends of the misaligned fiber and the fusion splice fiber are parallel to the clamped end of the initial fiber.

[0009] The fusion splicing and cleaving module includes a fusion splicing sub-module and a cleaving sub-module arranged axially side by side along one end of the initial optical fiber that is clamped; the fusion splicing sub-module includes a first image acquisition unit and a fusion splicing unit; the cleaving sub-module includes a second image acquisition unit and a cleaving unit.

[0010] The first image acquisition unit is used to acquire images of the initial optical fiber and the misaligned optical fiber entering the fusion splicing unit, obtain the first image, and send it to the computer module. The computer module identifies the axial distance and radial distance between the initial optical fiber and the misaligned optical fiber based on the first image, obtains the first axial distance and the first radial distance, and controls the fusion splicing unit to discharge when the first axial distance is zero and the first radial distance is a preset distance, so as to obtain the misaligned fusion spliced ​​optical fiber.

[0011] The second image acquisition unit is used to acquire images of the misaligned fusion fiber entering the cutting unit, obtain a second image, and send it to the computer module. The computer module identifies the misaligned fusion point based on the second image, determines the cutting point based on the misaligned fusion point, and then controls the cutting unit to cut at the cutting point to obtain an initial fiber with a preset length of misaligned fiber fusion.

[0012] The first image acquisition unit is also used to acquire images of the initial fiber and the fusion fiber, which are fused with misaligned fibers of a preset length, entering the fusion splicing unit, to obtain a third image and send it to the computer module. The computer module identifies the axial distance between the misaligned fiber and the fusion fiber and the radial distance between the initial fiber and the fusion fiber based on the third image, obtains the second axial distance and the second radial distance, and controls the fusion splicing unit to discharge when both the second axial distance and the second radial distance are zero, so as to obtain the fiber misaligned fusion splicing structure.

[0013] According to the specific embodiments provided in this application, this application has the following technical effects:

[0014] This application provides an integrated automatic fiber optic cleaving and splicing system. By utilizing image recognition technology, it acquires and identifies images of the initial fiber and misaligned fiber entering the splicing unit, obtaining the axial and radial distances between them. When the first axial distance is zero and the first radial distance is a preset distance (meeting the misalignment requirement), the splicing unit is controlled to discharge, thus obtaining misaligned fused fibers. Furthermore, by controlling the first and second fiber control modules, the misaligned fused fibers can be moved along the fiber axis and enter the cleaving unit, thereby acquiring images of the misaligned fused fibers entering the cleaving unit. The process involves collecting and identifying the misaligned fusion splice points and cutting points, and controlling the cutting unit to cut the fiber to obtain an initial fiber with a pre-set length of misaligned fiber. Then, by controlling the second fiber control module to move radially and axially, the fusion fiber can enter the fusion unit. Images of the initial fiber with the pre-set length of misaligned fiber and the fusion fiber inside the fusion unit are acquired and identified to obtain the axial distance between the misaligned fiber and the fusion fiber, as well as the radial distance between the initial fiber and the fusion fiber. When both distances are zero (meeting the misalignment requirement), the fusion unit is controlled to discharge, resulting in a misaligned fiber fusion splice structure. Based on this scheme, this application achieves automated manufacturing of the fiber optic misaligned fusion splice structure, significantly improving manufacturing efficiency.

[0056] Example 2

[0057] This embodiment includes various implementation methods in Embodiment 1, and describes the implementation method of the second fiber optic control module.

[0058] like Figure 2 As shown, the integrated automatic fiber optic cleaving and splicing system provided in this embodiment includes: a light source module 2, a fiber optic circulator 3, a spectral signal demodulation and processing module 1, a data connection line 4, an initial fiber optic cable 6, an initial fiber optic clamp 9, an axial movement guide rail for the initial fiber optic clamp 7, a motor 5 controlling the initial fiber optic clamp 5, a motor 18 controlling the fiber optic clamp tray 18, a tension sensor 8, an automatic cleaving and splicing module 10, a fiber optic clamp tray 12, a misaligned fiber optic clamp 13, a misaligned fiber optic cable 14, a spliced ​​fiber optic clamp 16, a spliced ​​fiber optic cable 17, a radial movement guide rail for the fiber optic clamp tray 11, an axial movement guide rail for the fiber optic clamp tray 15, and a computer module 19.

[0059] The initial fiber optic clamp is the first clamp in Embodiment 1, the axial movement guide rail of the initial fiber optic clamp is the third guide rail in Embodiment 1, the motor controlling the initial fiber optic clamp is the first clamp motor in Embodiment 1, and the automatic cutting and splicing module is the splicing and cutting module in Embodiment 1.

[0060] The motor 18 controlling the fiber optic clamp tray, the fiber optic clamp tray 12, the misaligned fiber optic clamp 13, the fusion splicing fiber optic clamp 16, the radial moving guide rail 11 of the fiber optic clamp tray, and the axial moving guide rail 15 of the fiber optic clamp tray constitute the second fiber optic control module in Embodiment 1.

[0061] The light source module 2 contains a broadband light source, which is connected to the optical fiber circulator 3 and the spectral signal demodulation and processing module 1 to form an optical path. It provides the emitted optical signal for the manufacturing of the optical fiber misalignment fusion splice structure. The emitted optical signal is input to the optical fiber misalignment fusion splice structure through the optical fiber circulator, which facilitates the spectral monitoring of the optical fiber misalignment fusion splice structure.

[0062] The fiber optic circulator 3, connected to the light source module 2, transmits the received transmitted light signal unidirectionally to the initial fiber 6, which then transmits it to the fiber misalignment fusion splice structure. It also receives the reflected light signal generated by the fiber misalignment fusion splice structure from the initial fiber 6 and transmits the reflected light signal unidirectionally to the spectral signal demodulation and processing module 1. The module demodulates the signal to obtain a spectral signal and transmits it as an electrical signal to the computer module 19 for processing via the data connection line 4.

[0063] The three fiber optic connectors of the fiber optic circulator 3, each with different transmission characteristics, are connected to the fiber optic light source module 2, the fiber optic misaligned fusion splice structure, and the spectral signal demodulation and processing module 1, respectively. The fiber connected to the fiber optic misaligned fusion splice structure is the initial fiber, and the other two connecting fibers can be the same as the initial fiber.

[0064] Fiber optic circulators are commercially available fiber optic devices that have been industrialized and are used for unidirectional transmission of light source signals and collection of reflected light signals from optical fibers.

[0065] The spectral signal demodulation and processing module 1 includes a multi-channel fiber optic grating demodulator, which receives the reflected and transmitted light signals generated by the optical fiber misalignment fusion splicing structure, demodulates them into spectral signals, and then converts them into electrical signals, which are then transmitted to the computer module for processing via the data connection line 4.

[0066] Data connection cable 4 connects the light source module 2, the spectral signal demodulation and processing module 1, the automation module, the tensile sensor 8, and the automatic cutting and welding module 10 to the computer module 19, and is used to transmit the identified images, measured data, feedback parameters, and send control commands to each module.

[0067] The optical fibers can be divided into initial fiber 6, misaligned fiber 14, and fusion splice fiber 17 according to their positioning. They are fixed on the initial fiber holder 9, the misaligned fiber holder 13, and the fusion splice fiber holder 16, respectively, to ensure that the axes of the two fibers coincide or remain parallel during fusion splicing and cutting. Among them, the misaligned fiber holder 13 and the fusion splice fiber holder 16 are located on the same side and are fixed on the fiber holder tray 12.

[0068] The initial fiber 6 serves as the substrate for the fiber misalignment fusion splice structure. The initial fiber 6 is spliced ​​with the misaligned fiber via misalignment fusion splicing at its end face.

[0069] The misaligned fiber 14 is fused with the initial fiber 6 and then cut to form a misaligned fiber structure.

[0070] After the fiber misalignment structure is cut, the fusion splice fiber 17 is aligned with the initial fiber 6 on the other side to form an optical interference cavity, and is connected to the spectral signal demodulation and processing module 1 to transmit transmitted light.

[0071] The three types of optical fibers mentioned above do not need to be the same. Most optical fiber misalignment structure sensors currently under research use the same type of initial optical fiber and splice fiber. The misalignment fiber can be a special fiber such as hollow fiber, coreless fiber, or dual-core fiber to improve the sensitivity of the sensor. Therefore, different types of optical fibers can be spliced ​​without the need for the same type of fiber. In some embodiments, depending on the performance of the required optical fiber misalignment splice structure, different types of optical fibers such as single-mode silica fiber, multimode fiber, few-mode fiber, hollow fiber, and coreless fiber can be selected for splicing and cutting, which can adapt to the production and manufacturing of different optical fiber misalignment splice structures.

[0072] There are three fiber optic clamps, mainly used to fix the initial fiber 6, the misaligned fiber 14 and the fusion splice fiber 17, and to keep their axes parallel or coincident.

[0073] In this embodiment, the combination of the motor 5 that controls the initial fiber optic clamp, the motor 18 that controls the fiber optic clamp tray, the fiber optic clamp tray 12, the radial moving guide rail 11 of the fiber optic clamp tray, and the axial moving guide rail 15 of the fiber optic clamp tray is referred to as the automation module.

[0074] The motor 5, which controls the initial fiber optic clamp, is used to control the initial fiber optic clamp 9 to move precisely along the axial moving guide rail 7 of the initial fiber optic clamp in the direction of the fiber optic axis. The motor 18, which controls the fiber optic clamp tray, is used to control the fiber optic clamp tray 12, which carries the misaligned fiber optic clamp 13 and the fusion splice fiber optic clamp 16, to move precisely along the radial moving guide rail 11 or the axial moving guide rail 15 of the fiber optic clamp tray. Together with the automatic cutting and splicing module 10, the position and axial tension of the fiber are adjusted to perform fiber optic splicing and cutting.

[0075] The function of the fiber optic clamp tray 12 is to fix two or more fiber optic clamps on the same horizontal plane and enable them to move precisely along the fiber axial direction or the fiber radial direction on the guide rail.

[0076] Using the automation module, the computer module 19 can automatically move and deliver the initial optical fiber 6, the misaligned optical fiber 14 and the fusion splice optical fiber 17 according to the program, and send them to the corresponding positions. The entire process does not require manual operation. The optical fiber can be automatically manufactured simply by placing the optical fiber into the optical fiber holder before the start of manufacturing.

[0077] The motor 18 controlling the fiber optic clamp tray is mainly used to drive the fiber optic clamp tray to move on two mutually perpendicular guide rails. The two guide rails are in a staggered position. One guide rail (fiber optic clamp tray axial movement guide rail 15) restricts the fiber optic clamp tray to move along the fiber axial direction, and the other guide rail (fiber optic clamp tray radial movement guide rail 11) restricts the fiber optic clamp tray to move along the fiber radial direction. The guide rail restricting radial movement is located at the bottom, and it supports the guide rail restricting axial movement to move radially, while the guide rail restricting axial movement supports the fiber optic clamp tray to move axially.

[0078] The tension sensor 8 is installed (integrated) on the initial fiber holder 9. It is mainly used to detect the axial tension of the fiber before cutting and the axial tension of the manufactured fiber misalignment fusion structure, and feeds it back to the computer module 19 to adjust the tension threshold. This ensures that the initial fiber and the misaligned fiber can be straightened after fusion splicing, making it easy to cut without breaking, and also detects whether the manufactured fiber misalignment fusion structure is qualified.

[0079] By setting a tension threshold, the motor-driven fiber optic clamp and fiber optic clamp tray are automatically stopped from moving the fiber optic axis. This ensures that a certain stress (approximately 80-100mN) is applied to the fiber without breaking the misaligned fusion splice structure, facilitating subsequent processes.

[0080] The automatic cutting and splicing module 10 includes an image detection and recognition module, an optical fiber splicing module, and an optical fiber cutting module. The image detection and recognition module uses image recognition and processing technology to measure parameters such as the type, position, misalignment amount, and length of the optical fiber misalignment splice structure in real time, and feeds them back to the computer module 19.

[0081] In this embodiment, the image detection and recognition module is equivalent to the first image acquisition unit and the second image acquisition unit in Embodiment 1; the fiber optic fusion splicing module is equivalent to the fusion splicing unit in Embodiment 1; and the fiber optic cleaving module is equivalent to the cleaving unit in Embodiment 1.

[0082] The initial fiber 6, misaligned fiber 14, and fusion splice fiber 17 will be manufactured in the automatic fusion splicing and cutting module 10. The computer module 19 controls the fiber fusion splicing module and fiber cutting module to respectively achieve the splicing and cutting of the misaligned fusion splice structure, thus completing the manufacturing of the misaligned fusion splice structure. The entire operation can be seamlessly connected through an automated program, requiring no additional manual intervention.

[0083] The automatic cutting and splicing module 10 integrates fiber optic splicing and fiber optic cutting functions into one module, enabling seamless connection operations and significantly reducing the manufacturing time of fiber optic misalignment splicing structures.

[0084] In other embodiments, fiber optic fusion splicing and automation modules can be used to adjust the positions of both ends of the same fiber to create other special fiber optic structures such as S-cones to meet usage requirements.

[0085] The computer module uses images acquired by the image detection and recognition module to perform real-time identification and measurement of parameters such as the position, misalignment, and length of the fiber optic misalignment fusion splice structure. It then outputs corresponding control commands to instruct the automation module to adjust the position of the initial fiber, the misaligned fiber, or the fusion splice fiber. Furthermore, the automatic cutting and splicing module, receiving control commands, adjusts the parameters of the fiber cutting or splicing process, achieving intelligent manufacturing. Different programs can be set to quickly switch between fabrication processes for fiber optic misalignment fusion splices with different performance characteristics.

[0086] Computer module 19 has built-in dedicated software for manufacturing fiber optic misaligned fusion splice structures. It can process feedback signals such as images, data, and parameters transmitted from various modules via data connection line 4. According to the parameter values ​​set in the program, it controls the motor 5 of the initial fiber optic holder and the motor 18 of the fiber optic holder tray to calibrate and adjust the fiber position. It also controls the fiber optic fusion splice module and fiber optic cutting module in the automatic cutting and splicing module 10 to adjust and calibrate the parameters, perform cutting and misaligned fusion splicing of the fiber optic misaligned fusion splice structure, and complete the manufacturing of the fiber optic misaligned fusion splice structure. It can also visualize and analyze the online real-time quality of the fiber optic misaligned fusion splice structure through the spectral signal demodulation and processing module 1.

[0087] The integrated automatic fiber optic cleaving and splicing system provided in this embodiment (combining image recognition and processing technology, automation modules, and computer programming control) enables fully automated manufacturing of fiber optic misaligned fusion splice structures. Furthermore, it can monitor the performance and quality of the fiber optic misaligned fusion splice structures in real time, simplifying the cumbersome and complex manufacturing process, improving manufacturing efficiency and standardization, and effectively enhancing the repeatability of fiber optic misaligned fusion splice structure manufacturing.

[0088] The integrated automatic fiber optic cutting and splicing system can operate and monitor the entire manufacturing process of the fiber optic misalignment splicing structure through the program set by the computer module 19, and make real-time parameter fine-tuning based on the spectral signal to realize the automated production and manufacturing of the fiber optic misalignment splicing structure.

[0089] See Figure 3 This is a schematic diagram of the internal structure of the automatic cutting and welding module 10.

[0090] The automatic cutting and splicing module 10 comprises an automatic cutting and splicing module base 20, a splicing electrode control module 21, a splicing electrode 22, an optical fiber slot 23, a guide rail 24 for controlling the movement of the splicing electrode, a splicing electrode support 25, a hinge structure 26, an automatic cutting and splicing module top cover 27, an image acquisition unit base 28, an image acquisition unit 29, an illumination lamp 30, a motor 31 for controlling the sapphire cutting blade, a sapphire cutting blade support 32, a sapphire cutting blade 33, a moving guide rail 34 for the sapphire cutting blade support and the auxiliary cutting base plate support, an auxiliary cutting base plate 35, an auxiliary cutting base plate support 36, and a motor 37 for controlling the auxiliary cutting base plate.

[0091] Fiber optic slot 23 generally refers to the first fiber optic slot and the second fiber optic slot in the embodiment; guide rail 24, which controls the movement of the fusion splice electrode, is the first guide rail in embodiment 1; sapphire dicing blade support and auxiliary cutting base plate support moving guide rail 34 is the second guide rail in embodiment 1; and auxiliary cutting base plate 35 is the cutting base plate in embodiment 1.

[0092] The automatic cutting and splicing module base 20 serves as the base of the entire automatic cutting and splicing module 10, and includes multiple modules such as the fiber optic splicing module, fiber optic cutting module, and fiber optic slot 23 fixed on it.

[0093] Fiber optic slots 23 are installed on both sides of the automatic cleaving and splicing module base 20 to support the initial fiber 6, the misaligned fiber 14, and the spliced ​​fiber 17, preventing adverse effects caused by shaking during the splicing and cleaving processes. The main function of the fiber optic slots is to support the fibers and keep them horizontal. The fibers are pre-placed in the corresponding fiber optic holders.

[0094] The removal and switching of misaligned and fusion spliced ​​optical fibers are automatically completed under the control of computer module 19.

[0095] The fusion electrode 22, the fusion electrode control module 21, the guide rail 24 for controlling the movement of the fusion electrode, and the fusion electrode support 25 constitute the optical fiber fusion splicing module. The fusion electrode 22 is installed on the fusion electrode support 25 and is used to discharge and melt the end face of the optical fiber during the fabrication of the optical fiber misalignment fusion splicing structure. The energy of the discharge causes the optical fiber to melt and bond instantly, and then cools and solidifies to achieve fusion splicing.

[0096] The welding electrode control module 21 can not only adjust the parameters such as discharge quantity, discharge time, and mode of the welding electrode 22 according to the control instructions of the computer module 19 transmitted through the data connection line 4, but also control the welding electrode support 25 to move on the guide rail 24 that controls the movement of the welding electrode, so as to change the discharge position of the welding electrode 22.

[0097] The welding electrode control module 21 has its own motor.

[0098] The fusion electrode control module regulates the effect of misaligned fusion by controlling the discharge amount and discharge time of the electrodes. Excessive discharge intensity or duration will cause damage and scorching on the surface of the optical fiber misaligned fusion structure, preventing it from working properly. Fixed values ​​can be preset to control the discharge amount and time to achieve the best effect.

[0099] The fiber optic cutting module consists of a motor 31 that controls the sapphire cutting blade, a sapphire cutting blade support 32, a sapphire cutting blade 33, a moving guide rail 34 for the sapphire cutting blade support and the auxiliary cutting base plate support, an auxiliary cutting base plate 35, an auxiliary cutting base plate support 36, and a motor 37 that controls the auxiliary cutting base plate.

[0100] The sapphire dicing blade 33 is fixed on the sapphire dicing blade support 32, and together with the auxiliary cutting base plate 35 fixed on the auxiliary cutting base plate support 36, they form a cutting tool for cutting misaligned optical fibers 14. The motor 31 controlling the sapphire dicing blade and the motor 37 controlling the auxiliary cutting base plate can receive control commands from the computer module 19 via the data connection line 4, respectively controlling the sapphire dicing blade support 32 and the auxiliary cutting base plate support 36 to move on the moving guide rails 34 of the sapphire dicing blade support and the auxiliary cutting base plate support, thereby achieving precise cutting of the misaligned fusion splice structure of the optical fiber.

[0101] The top cover 27 of the automatic cutting and welding module is connected to the base 20 of the automatic cutting and welding module via a hinge structure 26. The automatic cutting and welding module 10 can be opened or closed by flipping the top cover 27. The top cover 27 of the automatic cutting and welding module is equipped with an image detection and recognition module and a lighting lamp 30.

[0102] The main body of the image detection and recognition module consists of four image acquisition units 29 (CCDs), divided into two groups, used to acquire images from the fiber optic splicing module and the fiber optic cleaving module respectively. These units are mounted on image acquisition unit bases 28 at a 45° angle (preset tilt angle) to the top cover 27 of the automatic cleaving and splicing module. The focal points of two image acquisition units 29 in the same group coincide, and their lens axes intersect perpendicularly, enabling the acquisition of fiber optic images from two perpendicular perspectives, thus improving the accuracy of positioning and measurement.

[0103] The image acquisition unit 29 in this embodiment is equivalent to the camera in embodiment 1.

[0104] The illumination lamp 30 provides lighting in dark environments, which is beneficial for the image detection and recognition module to acquire images and for the computer module to accurately locate the fiber optic position and measure parameters. After image acquisition, the image detection and recognition module transmits the image to the computer module 19 in real time via the data connection line 4 for processing. The computer module 19 then issues control commands for calibration to manufacture the fiber optic misalignment fusion splice structure.

[0105] The image recognition and processing algorithms are relatively basic and simple, based on deep learning and machine learning, involving image thresholding. Specifically, thresholding identifies the exact positions of the left and right optical fibers, calculates the pixel coordinates of their axes and end faces, and then adjusts the two fibers to the specified coordinate positions as needed. In terms of measurement, the number of pixels in the thresholded image (i.e., the misaligned structure image) is converted into the actual length.

[0106] See Figure 4 This is a flowchart of the manufacturing process for an optical fiber misaligned fusion splice structure. The manufacturing of the optical fiber misaligned fusion splice structure mainly consists of three steps.

[0107] The first step is the misaligned fusion splicing of the initial fiber 6 and the misaligned fiber 14.

[0108] 1.1) The initial fiber 6 and the misaligned fiber 14 are moved into the automatic cutting and splicing module 10 by the motor 5 controlling the initial fiber holder and the motor 18 controlling the fiber holder tray, while keeping the fiber cores 38 aligned.

[0109] 1.2) Provided that the end face of the fiber core 38 is not blocked by the fiber cladding 39, after the image acquired by the image acquisition unit 29 is measured (recognized) by the computer module 19, the misaligned fiber 14 is moved radially upward or downward to a set distance by controlling the motor 5 of the initial fiber holder and the motor 18 of the fiber holder tray, so as to achieve the misalignment effect.

[0110] 1.3) After the radial movement is completed, control the initial fiber 6 and the misaligned fiber 14 to move axially to eliminate the axial gap.

[0111] 1.4) Discharge fusion is performed by fusion electrode discharge 40 to obtain the misaligned fusion fiber of the initial fiber 6 and the misaligned fiber 14.

[0112] The setting distance depends on the type of misaligned fiber. Generally, for Fabry-Perot fiber sensors, a misalignment length of 50-150 μm can achieve the light interference effect. The misalignment distance depends on the fiber type; specifically, it should be greater than the "core diameter + cladding radius" to ensure that the misaligned structure does not obstruct the fiber core (e.g., the misalignment distance for single-mode fiber is often 65-90 μm).

[0113] The second step is to cut the misaligned fiber 14 to form the fiber misalignment structure 41.

[0114] 2.1) First, by controlling the motor 5 of the initial fiber holder and the motor 18 of the fiber holder tray to move synchronously, the initial fiber 6 and the misaligned fusion fiber of the misaligned fiber 14 are moved to the fiber optic cleaving module.

[0115] 2.2) Then, by controlling the motor 5 of the initial fiber holder and the motor 18 of the fiber holder tray to move in opposite directions, the misaligned fusion fiber of the initial fiber 6 and the misaligned fiber 14 is straightened.

[0116] 2.3) After straightening, the image of the initial fiber 6 and the misaligned fiber 14 captured by the image acquisition unit 29 is transmitted to the computer module 19 to measure (identify) the length of the misaligned fiber fusion structure and locate the cutting point (i.e., the cutting point).

[0117] 2.4) By controlling the motor 37 of the auxiliary cutting base plate, the center of the auxiliary cutting base plate 35 is pressed against the cutting point of the misaligned optical fiber 14. By controlling the motor 31 of the sapphire cutting blade, the sapphire cutting blade 33 is controlled to move towards the center of the auxiliary cutting base plate 35, and finally contacts the misaligned optical fiber 14 and cuts it to form the optical fiber misalignment structure 41.

[0118] In some instances, when computer module 19 measures length, the scale lines are marked in the software, and the number of pixels serves as the scale standard in the computer software. The length can be calculated based on the ratio of the image to the actual size, and the measured length is obtained by converting the number of pixels.

[0119] The third step is to fuse the optical fiber misalignment structure 41 and the fusion fiber 17 into an optical interference cavity.

[0120] 3.1) By controlling the motor 5 of the initial fiber optic clamp, the fiber misalignment structure 41 is moved to the fiber optic splicing module.

[0121] 3.2) Remove the remaining misaligned optical fiber 14 by controlling the motor 18 of the optical fiber holder tray.

[0122] 3.3) Move the fusion splice fiber 17 to the right side of the fiber misalignment structure 41 so that the initial fiber 6 coincides with the fiber core 38 of the fusion splice fiber 17.

[0123] 3.4) Subsequently, the fusion electrode discharge 40 is controlled to fuse the optical fiber misalignment structure 41 and the fusion fiber 17 into an optical interference cavity, thus completing the manufacturing of the optical fiber misalignment fusion structure.

[0124] The entire process of the above steps is carried out intelligently by computer module 19, realizing automated manufacturing.

[0125] See Figure 5 This is a schematic diagram illustrating the working principle of the optical fiber misalignment fusion splicing structure.

[0126] The optical fiber misalignment fusion splice structure is mainly composed of the initial optical fiber 6, the fusion splice optical fiber 17, and the optical fiber misalignment structure after the misalignment optical fiber 14 is cut.

[0127] When the optical fiber does not have a misalignment structure, the incident light 43 enters from the end face of the fiber and undergoes total internal reflection at the junction of the fiber cladding and the fiber core, confining the light to propagate within the fiber core 38, thus preventing significant optical interference. Therefore, after the incident light passes through a section of ordinary optical fiber structure, the reflection spectrum of the reflected light 42 and the transmission spectrum of the transmitted light 44 will not form an interference spectrum with obvious peaks and troughs.

[0128] When incident light 43 passes through the optical fiber misalignment fusion splice structure with an optical interference cavity, the reflected light with a phase difference at the two end faces of the optical interference cavity will interfere when they meet, thus forming a reflection spectrum with obvious peaks and valleys. Similarly, the transmitted light with a phase difference at the two end faces of the interference cavity will also interfere when they meet, thus forming a transmission spectrum that is complementary to the reflection spectrum.

[0129] Both the reflection and transmission spectra can be monitored using the spectral signal demodulation and processing module 1. Based on the transmission and reflection spectra, parameters such as the free spectral range (FSR) and contrast can be used to evaluate in real time whether the fiber misalignment fusion splice structure meets the standards. For example, according to the calculation formula... The range of the free spectral region can be calculated, where, The incident light wavelength, Effective refractive index within the optical interference cavity The optical interference cavity length (FSR) is the length of the fiber optic misalignment fusion splice structure. The FSR reflects the interference pattern and also determines the performance of the interferometer and sensor. An excessively large FSR hinders detection, while an excessively small FSR increases detection costs. A suitable FSR allows for better application in optical detection and sensing. Therefore, FSR is a crucial evaluation indicator for the quality of fiber optic misalignment structures, and different FSRs allow for adaptability to various applications.

[0130] A major reason for the poor repeatability in manufacturing common fiber misalignment fusion splice structures is the inability to effectively control the length of the fiber misalignment fusion splice structure. The length of the fiber optic automatic cleaving and splicing integrated system provided in this application can be controlled with high precision within a very small range through image recognition and processing technology and a self-calibration program. The process involves cutting and mass-producing fiber optic misalignment fusion splices with specific FSRs. Automated manufacturing also effectively reduces human error and tedious operations in manual manufacturing, overcoming the poor repeatability issues of common fiber optic misalignment fusion splice manufacturing methods.

[0131] The above technical solution has the following advantages, unlike existing technologies:

[0132] 1) An integrated automatic fiber optic cleaving and splicing system is used to manufacture the fiber optic misalignment splice structure. Among other things,

[0133] The automatic cutting and splicing module can be controlled by a computer module to perform splicing of optical fiber misalignment splicing structures with specific misalignment amounts and to cut optical fiber misalignment splicing structures of specific lengths, thereby enabling customized production and manufacturing of optical fiber misalignment splicing structures.

[0134] The automation module, controlled by the computer module, precisely moves the optical fiber, working in conjunction with the automatic fusion splicing and cutting module to complete the fiber splicing and cutting processes, thus manufacturing the misaligned fusion splice structure. The entire process can be fully automated and rapid through the computer module, eliminating the need for manual operation.

[0135] 2) Image recognition and processing technology is used to perform image detection and recognition during the manufacturing process of the fiber optic misalignment fusion splice structure, providing real-time precise positioning of the fiber optic position based on the image; real-time precise measurement of the misalignment amount and the length of the fiber optic misalignment fusion splice structure; the positioning and measurement data are fed back to the computer module, which compares the parameters specified in the program with the parameters measured after image recognition, and outputs a signal to control the automation module to adjust the fiber optic position, the corresponding parameters of the fiber optic splicing program and the fiber optic cutting program of the automatic cutting fusion module; the above process is repeated continuously with feedback until the measured parameters are consistent with the specified parameters, at which point the feedback stops and calibration is completed. Compared with the common manufacturing process of fiber optic misalignment fusion splices, the process of using image recognition and processing technology for parameter measurement and feedback to achieve self-calibration effectively improves the manufacturing accuracy, repeatability, and standardization level of fiber optic misalignment fusion splices.

[0136] By combining a tension sensor with an automation module, the axial force on the optical fiber in a misaligned fusion splice structure is monitored before cutting and after splicing. Before cutting, maintaining a certain axial tension ensures a smooth cutting process and a flatter fiber end face. After splicing, the automation module performs a tension test on the fiber structure to check its manufacturing quality. The tension sensor monitors the tension values ​​in both processes and allows for threshold control of the applied axial tension, facilitating management and adjustment of the manufacturing process. Compared to common optical fiber misaligned fusion splice manufacturing processes, this combination of tension sensors and automation modules offers greater intelligence and controllability, enabling more flexible monitoring and adjustment of parameters during production.

[0137] As a further optimization of the technical solution, the number of fiber optic clamps and the number of fibers that a single fiber optic clamp can hold can be increased. This increases the reserve of initial fibers, misaligned fibers, and fusion splice fibers before manufacturing begins. Automated modules can be used to continuously manufacture multiple fiber misaligned fusion splice structures, and supplementing fibers during production will not affect the manufacturing process, forming a production line and effectively improving manufacturing efficiency.

[0138] As a further optimization of the technical solution, the fiber misalignment fusion splice structure is relatively fragile after manufacturing. The splice point is prone to breakage and damage when subjected to radial force. Small fiber clamping devices that can be plugged in and unplugged at one time can be set on both sides of the automatic cutting fusion splice module to ensure that the fiber misalignment fusion splice structure can be straightened after manufacturing and can be easily removed and stored, reducing the breakage and damage caused by human factors, environment and other factors when the fiber misalignment fusion splice structure is removed.

[0139] As a further optimization of the technical solution, the fiber optic fusion splicing module and fiber optic cleaving module in the automatic cleaving and splicing module have fusion and cleaving functions. Additional functional modules, such as sputtering coating and surface polishing modules, can be added to achieve more functions. Additional programs can be added to continue to perform these functions after the fiber misalignment fusion splicing structure is completed. Custom manufacturing of interferometers and sensors is achieved by integrating the fabrication process of fiber optic interferometers and fiber optic sensors based on the interference principle into the integrated automatic fiber optic cleaving and splicing system, thus broadening the system's functions and applications.

[0140] As a further optimization of the technical solution, if there is instability in the optical fiber during the cutting and splicing process, it may lead to deviations in the splicing and cutting process. Additional controllable V-grooves can be added to the optical fiber splicing module and the optical fiber cutting module to limit the radial movement and vibration of the optical fiber, ensure that the optical fiber remains stable during the splicing and cutting process, and improve the reliability of the splicing and cutting process.

[0141] In this embodiment, by combining a computer-aided visual operating program, fiber optic cleaving equipment, and fiber optic fusion splicing equipment, and utilizing image recognition and processing technology with the automated operation of these two devices, intelligent manufacturing of fiber optic misaligned fusion splice structures is achieved. The entire manufacturing process of the fiber optic misaligned fusion splice structure is completed within the integrated automatic fiber optic cleaving and fusion splicing system. Through image recognition and processing technology, the system can accurately locate the position of the fiber optic misaligned fusion splice point and the length of the fiber optic misaligned fusion splice structure. It can perform precise fiber optic misaligned fusion splicing and precise length cutting of the fiber optic misaligned fusion splice structure. These two steps are seamlessly integrated within the system, significantly reducing the tedious manual operations involved in manufacturing fiber optic misaligned fusion splice structures, lowering time costs, increasing production efficiency, and enabling the industrialization and standardization of fiber optic misaligned fusion splice structure manufacturing. During the manufacturing process, the spectral signal demodulation and processing module can also monitor the spectrum of the fiber optic misaligned fusion splice structure to ensure its performance.

[0142] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0143] This document uses specific examples to illustrate the principles and implementation methods of this application. The descriptions of the above embodiments are only for the purpose of helping to understand the methods and core ideas of this application. Furthermore, those skilled in the art will recognize that, based on the ideas of this application, there will be changes in the specific implementation methods and application scope. Therefore, the content of this specification should not be construed as a limitation of this application.
