Description

Technical Field

[0001] This invention relates to the technical field of forming several optical fibers, and in particular to an optical fiber reversal control system based on a spacing-changing optical fiber array. Background Technology

[0002] Fiber optic arrays are the most widely used devices in the fields of fiber optic sensing and flexible lighting. They are mainly used in planar waveguide devices, flexible lighting displays, arrayed waveguide grating communication networks, and dense wavelength division multiplexing.

[0003] For example, CN209327610U discloses a fiber optic array winding device with adjustable spacing. Typically, the precise arrangement of fiber optic arrays requires creating V-grooves on the backplane using chemical etching or digital processing techniques, then placing the fibers in these grooves and bonding them with adhesives. This type of fiber optic array manufacturing process is complex, difficult to operate, and not easy to produce. Precise arrangement of large-area fiber optic arrays with arbitrarily adjustable spacing requires precise arrangement and design of each fiber in the array. It requires thousands of fibers to be arranged parallel to each other on two horizontal planes with fixed spacing. Fiber optics are small in size, typically with a diameter between 0.25mm and 1mm, and are flexible and easily damaged. Fiber optics usually consist of a core and cladding, with the core being the key component, made of polymethyl methacrylate (PMMA). The cladding is usually made of fluorinated polymer, which mainly protects the core and improves the optical transmission efficiency of the fiber. Plastic optical fibers are generally very easy to damage. During the arrangement of optical fiber arrays, it is required that the core and cladding structures of the optical fibers not be damaged.

[0004] Another typical example is the fiber optic array element manufacturing method disclosed in prior art CN1226642C. The core of existing fiber optic array element manufacturing technology is the use of V-groove technology. In this process, precise V-groove components with a defined number of channels are first fabricated, and then single-mode bare fibers are precisely assembled into the corresponding V-grooves. The positioning accuracy of the fiber array is determined by the etching accuracy of the V-grooves and the assembly accuracy of the components. In existing fiber optic array element manufacturing processes, the precise V-groove components require high-precision manufacturing equipment; precisely assembling the single-mode bare fibers into the corresponding V-grooves is also a challenging process. Consequently, the yield is very low, generally below 50%. Therefore, manufacturing fiber optic array elements using the V-groove process is complex, requires significant investment, has a low yield, and results in high production costs.

[0005] This invention was developed to address the common problems in the field, such as complex manufacturing processes, low yield, low winding accuracy, low detection accuracy, easy damage during manufacturing, inability to dynamically adjust fiber arrangement, and low intelligent length. Summary of the Invention

[0006] The purpose of this invention is to address the shortcomings of current methods by proposing a fiber optic direction-changing control system based on a fiber optic array with varying spacing.

[0007] To overcome the shortcomings of the prior art, the present invention adopts the following technical solution:

[0015] Based on the difference ΔR between the maximum and minimum gray values ​​of the adjacent peak and trough regions at the k-th detection location, and the average gray value Uniform at the k-th detection location... k Calculate the average index (Average) from the data:

[0016]

[0017] In the formula, L is the total number of detection positions of the fiber array;

[0018] If the average index exceeds the set monitoring threshold value, the pulling module is triggered to pull the fiber array.

[0019] Optionally, the reversing module includes a support base, a first inflatable component, and at least two limiting holes disposed on the support base, wherein the first inflatable component is used to restrict the optical fiber.

[0021] Optionally, the pull-out module includes a clamping unit and a pull-out unit, wherein the clamping unit is used to clamp the fiber array and the pull-out unit is used to pull out the fiber array.

[0022] The clamping unit includes a second inflatable component and a clamping seat. The clamping seat is used to support the optical fiber array, and the second inflatable component is used to clamp the optical fiber array.

[0023] The clamping base has a nesting cavity on its main body, and when clamping the optical fiber array, it is nested on the outer periphery of the optical fiber array, and the second inflatable component is disposed on the inner wall of the nesting cavity.

[0024] Optionally, the supply module includes a supply unit and a winding unit. The supply unit is used to supply the optical fiber cladding, and the winding unit is used to wind the optical fiber cladding so that the optical fiber cladding can be wound around the outer periphery of the multiple optical fibers aggregated by the direction-changing module to form an optical fiber array body.

[0025] The supply unit includes a supply cavity, a supply component, a supply rod, and a supply drive unit. The supply cavity stores the optical fiber cladding. The supply rod is disposed in the supply cavity and supports the optical fiber cladding. One end of the supply rod is driven to connect with the supply drive unit to form a supply section. The supply section is fixedly connected to the inner wall of the supply cavity. The other end of the supply rod extends vertically away from the inner wall of the supply cavity. The supply component supplies the optical fiber cladding, allowing the head of the optical fiber cladding to abut against the outer periphery of the multiple clustered optical fibers and to cooperate with the winding unit to wind the optical fiber cladding.

[0026] Optionally, the winding unit includes a winding member and a connecting seat. The connecting seat is used to support the winding member, and the winding member is used to wind the optical fiber cladding supplied by the supply unit, so that the optical fiber cladding can be wound around the periphery of the clustered optical fiber.

[0032] 2. After multiple optical fibers are gathered by the direction-changing module, the fiber cladding of the gathered optical fibers is wound by the supply module. At the same time, during the winding process, the fiber array body is gradually pulled so that it can pass through the position of the detection module in sequence, and the fiber array body is detected by the detection module.

The following embodiments will further describe the relevant technical content of the present invention in detail, but the disclosed content is not intended to limit the scope of protection of the present invention.

[0055] Example 1.

[0056] according to Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 , Figure 6 , Figure 7 , Figure 8 , Figure 9 , Figure 10 , Figure 11 , Figure 12 , Figure 13 and Figure 14 As shown, this embodiment provides an optical fiber reversal control system based on a pitch-changing optical fiber array 9. The optical fiber reversal control system includes a server, a V-groove component 1, an optical fiber cladding, and at least two optical fibers 8. The optical fiber reversal control system also includes a detection module, a reversal module, a supply module, and a pull-out module. The server is connected to the detection module, the reversal module, the supply module, and the pull-out module, respectively.

[0057] The direction-changing module is used to adjust the distribution spacing of each optical fiber 8, the supply module is used to supply the optical fiber cladding 14 and wind the optical fiber cladding 14 around the outer periphery of each distributed optical fiber 8 to form the main body of the optical fiber array 9, the detection module is used to detect the wound optical fiber array 9 main body, and the pulling module is used to pull the wound optical fiber array 9 main body.

[0058] The fiber optic reversing control system further includes a rack 18 and a central processing unit. The rack 18 supports the detection module, the reversing module, the supply module, and the pull-out module. Specifically, the detection module, the reversing module, the supply module, and the pull-out module are all mounted on the rack 18. The central processing unit is connected to the server, the detection module, the reversing module, the supply module, and the pull-out module for control, and performs centralized control of the server, the detection module, the reversing module, the supply module, and the pull-out module based on the central processing unit.

[0059] In this embodiment, the reversing module gathers multiple optical fibers 8 onto the V-groove component 1, so that the position of the optical fibers 8 can be reversed, improving the precise adjustment of each optical fiber 8 and meeting the processing requirements.

[0060] In this embodiment, the V-groove component is a technical means well known to those skilled in the art. Those skilled in the art can consult relevant technical manuals to learn about this technology, so it will not be described in detail in this embodiment.

[0061] After the multiple optical fibers 8 are gathered by the direction-changing module, the multiple gathered optical fibers 8 are wound with the optical fiber cladding 14 by the supply module. At the same time, during the winding process, the optical fiber array body is gradually pulled so that the optical fiber array body can pass through the position of the detection module in sequence, and the optical fiber array body is detected by the detection module.

[0062] The detection module includes a detection unit and an evaluation unit. The detection unit is used to acquire image data of the main body of the fiber array 9 formed by cladding winding, and the evaluation unit performs evaluation based on the image data of the detection unit.

[0063] The detection unit includes at least three detection probes 17, a fixing component 16, and a data storage device. Each detection probe 17 is used to acquire image data of the main body of the fiber array 9 formed by cladding winding. The fixing component 16 is used to fix the position of the detection probe 17. The data storage device is used to store the image data acquired by the detection probe 17.

[0064] Each of the detection probes 17 is disposed on the fixed member 16 to form a detection part, such that the detection parts are distributed at 60° angular intervals around the periphery of the main body of the fiber array 9.

[0065] The fixing component 16 includes a fixing seat, a lifting rod, a lifting drive mechanism, and a height detection component. The height detection component is used to detect the lifting height of the lifting rod. The lifting drive mechanism is driven to the lifting rod so that the lifting rod can perform telescopic movements. The fixing seat is used to support at least three detection probes 17.

[0066] The lifting rod is telescopic and its extension and retraction are controlled by the lifting drive mechanism. One end of the lifting rod is connected to the fixed base, and the other end of the lifting rod is connected to the upper end face of the frame 18.

[0067] The fixed member 16 supports the positions of the three detection probes 17, so that the positions of the detection probes 17 can be adjusted according to the type of the fiber array 9 produced.

[0068] It is worth noting that the fixing base is cylindrical, and the main body of the fixing base is provided with a circular receiving cavity for placing at least three of the detection probes 17, so that at least three of the detection probes 17 are fixedly mounted on the inner wall of the receiving cavity, and at the same time, the acquisition direction of at least three of the detection probes 17 is oriented towards the axis of the fixing base.

[0069] The evaluation unit acquires the image data and processes the image data, including converting the image data to grayscale to obtain a grayscale curve.

[0070] The difference between the maximum and minimum gray values ​​ΔR between the adjacent peaks and troughs at the k-th detection position on the fiber array body, and the average gray value Uniform at the k-th detection position, are obtained from the grayscale curve. k ;

[0071] Based on the difference ΔR between the maximum and minimum gray values ​​of the adjacent peak and trough regions at the k-th detection location, and the average gray value Uniform at the k-th detection location... k Calculate the average index (Average) from the data:

[0072]

[0073] In the formula, L is the total number of detection positions of the fiber array;

[0074] If the average index exceeds the set monitoring threshold value, the pulling module is triggered to pull the fiber array.

[0075] Through the cooperation of the detection unit and the supply module, the processing accuracy of the optical fiber array can be improved during the processing, ensuring a high pass rate for the entire optical fiber array.

[0076] In this embodiment, the monitoring threshold Value is set by the operator according to the type of fiber array being processed. This is a technical method well known to those skilled in the art. Those skilled in the art can consult the technical manual to learn about this technology. Therefore, it will not be described in detail in this embodiment.

[0077] Optionally, the reversing module includes a support base 3, a first inflatable component, and at least two limiting holes 6 disposed on the support base 3. The first inflatable component is used to restrict the optical fiber 8. The limiting holes 6 are disposed on the outer periphery of the support base 3 and are evenly distributed. The first inflatable component is disposed on the inner wall of each of the limiting holes 6 to restrict the optical fiber 8.

[0078] Meanwhile, each of the limiting holes 6 is provided with a placement cavity for storing the first inflatable component, and the first inflatable component is hidden in the placement cavity when the first inflatable component is not triggered.

[0079] The first inflatable component includes at least two first inflatable airbags 4 and a first inflatable pump 5. The first inflatable airbags 4 are used to adjust or turn the position and direction of the optical fiber 8 to achieve the purpose of turning. The first inflatable pump 5 is used to inflate the first inflatable airbags 4 so that the optical fiber 8 can adjust or turn its direction.

[0080] The first inflatable airbag 4 protects and adjusts the position of the optical fiber 8, so that the position of multiple optical fiber 8 can be precisely adjusted, improving the accuracy of the arrangement of optical fiber 8 and increasing the yield of optical fiber array 9 production.

[0081] In addition, the support base 3 has a passage cavity 7 on its main body for the V-groove component 1 to pass through, and the circumference of the passage cavity 7 is adapted to the corresponding model of the V-groove component 1 produced; at the same time, such as Figure 5 As shown, the V-groove component 1 is provided with a plurality of snap-fit ​​grooves 2, and each snap-fit ​​groove 2 is distributed at equal intervals along the circumference;

[0082] like Figure 8 As shown, the V-groove component 1 passes through the passage cavity and supplies fiber to the left (as indicated by the horizontal arrow in the figure). At this time, the optical fiber 8 passes through the first inflatable airbag 4, and by adjusting the first inflatable airbag 4, the optical fiber 8 can fall precisely into the snap-fit ​​groove 2, thereby allowing the fiber to pass through the passage cavity. Figure 8 The matching structure shown allows the first inflatable airbag 4 to protect and adjust the position of the optical fiber 8, thereby improving the accuracy of the arrangement of the optical fiber 8.

[0083] At the same time, Figure 8 In the figure, the optical fiber 8 is along the arrow ( Figure 8 (As indicated by the slanted arrow in the middle) is supplied so that multiple optical fibers can pass through the limiting hole, and then, through the clamping and limiting action of the first airbag, the optical fibers can fall into the snap-fit ​​groove 2 provided on the V-groove component 1.

[0084] In addition, the supply speed of the optical fiber 8 is adapted to the pulling speed of the pulling module to ensure that the optical fiber can fall correctly and just right into the snap-fit ​​groove 2 provided on the V-groove component 1.

[0085] Once the optical fiber can fall correctly into the snap-fit ​​groove 2 provided on the V-groove component 1, the optical fiber cladding will be wound around the outside of the V-groove component 1 to form the main body of the optical fiber array.

[0086] During the production of the fiber array 9, the V-groove component and each fiber 8 need to pass through the passage cavity 7 and the limiting hole 6 respectively, so that the end of the V-groove component and the end of the fiber 8 extend to the pull-out module and are clamped or limited by the pull-out module.

[0087] In this embodiment, the cooperation between the steering light module and the V-groove component enables the produced optical fibers 8 to be evenly arranged, improving the yield of the optical fiber array 9, increasing the processing accuracy of the optical fiber array 9, and greatly reducing the complexity of the processing of the optical fiber array 9.

[0088] It is worth noting that the V-groove component mentioned in this embodiment can be selected according to the appropriate model of the processed fiber array 9, so that each fiber 8 can be arranged effectively and accurately, thereby improving the accuracy and reliability of the production of the fiber array 9.

[0089] The optical fiber 8 is positioned by a direction-changing module to improve the processing accuracy of the optical fiber 8, ensure the precise control capability of the entire system, and enable the entire system to have the advantages of high yield, high winding accuracy of the optical fiber cladding 14, and less damage to the optical fiber.

[0090] Optionally, the pull-out module includes a clamping unit and a pull-out unit, wherein the clamping unit is used to clamp the fiber array 9, and the pull-out unit is used to pull out the fiber array 9.

[0091] The clamping unit includes a second inflatable component and a clamping seat 23. The clamping seat 23 is used to support the optical fiber array 9, and the second inflatable component is used to clamp the optical fiber array 9.

[0092] The clamping base 23 has a nesting cavity on its main body and is nested around the outer periphery of the fiber array 9 when clamping the fiber array 9. The second inflatable member is disposed on the inner wall of the nesting cavity.

[0093] Meanwhile, during the clamping process of the fiber array 9, after the second inflation member is inflated, it expands to clamp the fiber array 9 and, together with the pull-out unit, transports the fiber array 9 so that the fiber array 9 can be transported to the next process.

[0094] In this embodiment, the second inflation component includes a second inflation airbag 24, a second inflation pump 25, and a second pressure detection device. The second pressure detection device is disposed at the contact position between the second inflation airbag 24 and the optical fiber array 9. The second inflation pump 25 is used to inflate the second inflation airbag 24, so that the inflation airbag bulges out after inflation, so as to clamp or hold the optical fiber array 9.

[0095] The second inflatable airbag 24 is configured as an annular airbag and is hidden in the hidden cavity 26 on the inner wall of the clamping seat 23. When in the initial state, the second inflatable airbag 24 is hidden in the hidden cavity 26.

[0096] The pull-out unit includes a pull-out rail 21, a sliding plate 22, a connecting rod 20, a sliding drive mechanism 19, and a stand. The stand is used to support the sliding drive mechanism 19 and is located on one side of the pull-out rail 21. One end of the connecting rod 20 is hinged to the sliding plate 22, and the other end of the connecting rod 20 is hinged to the output shaft of the sliding drive mechanism 19 to form a pull-out part.

[0097] The sliding plate 22 is slidably connected to the sliding rail, and is pulled out along the direction of the sliding rail under the drive of the pull-out part;

[0098] like Figure 10 , Figure 12 As shown, the pull-out track 21 is slidably connected to the sliding plate 22;

[0099] Meanwhile, the clamping seat 23 is connected to the sliding plate 22 via a vertical rod, so that the clamping seat 23 can be adapted to the processing of different fiber arrays 9. The clamping seat 23 is located on the side of the sliding plate 22 away from the sliding track and is connected to the sliding plate 22 via a vertical rod.

[0100] In this embodiment, after the clamping unit clamps the fiber array 9, the pulling unit transports the clamping unit along with the fiber array 9 forward (to the next process), enabling the fiber array 9 to be produced efficiently. Specifically, after the clamping unit clamps the fiber array, the pulling unit transports the clamping unit forward. When the clamping unit reaches the end of the pulling track, the clamping unit releases the fiber array 9 and the pulling unit brings the clamping unit back to its initial position. At the initial position, the clamping unit clamps the fiber array 9 and transports the clamping unit along with the fiber array 9 forward (to the next process). This process is repeated multiple times to achieve the transportation of the fiber array 9.

[0101] Through the cooperation of the pulling unit and the clamping unit, each fiber array 9 can be gradually pulled backward after being wound, thereby improving the production efficiency of the entire fiber array 9 and ensuring the intelligence level of the entire system.

[0102] Optionally, the supply module includes a supply unit 10 and a winding unit. The supply unit 10 is used to supply the optical fiber cladding 14, and the winding unit is used to wind the optical fiber cladding 14 so that the optical fiber cladding 14 can be wound around the outer periphery of the plurality of optical fibers 8 formed by the direction-changing module to form the main body of the optical fiber array 9.

[0103] The supply unit 10 includes a supply cavity, a supply component 13, a supply rod 15, and a supply drive unit. The supply cavity is used to store the optical fiber cladding 14. The supply rod 15 is disposed in the supply cavity and supports the optical fiber cladding 14. One end of the supply rod 15 is driven to be connected to the supply drive unit to form a supply section. The supply section is fixedly connected to the inner wall of the supply cavity. The other end of the supply rod 15 extends vertically away from the inner wall of the supply cavity. The supply component 13 is used to supply the optical fiber cladding 14, so that the head of the optical fiber cladding 14 can abut against the outer periphery of the multiple clustered optical fibers 8 and cooperate with the winding unit to wind the optical fiber cladding 14.

[0104] Optionally, the winding unit includes a winding member and a connecting seat. The connecting seat is used to support the winding member, and the winding member is used to wind the optical fiber cladding 14 supplied by the supply unit 10, so that the optical fiber cladding 14 can be wound around the periphery of the clustered optical fiber 8.

[0105] The winding component includes a winding ring 11, a winding rod 27, a winding drive mechanism, and a fixing ring 12. The winding rod 27 is used to move the optical fiber cladding 14 so that the optical fiber cladding 14 is wound around the outer periphery of the clustered optical fiber 8. The winding ring 11 is used to support the winding rod 27 and the supply unit 10. The winding drive mechanism drives the winding ring 11 to rotate. The fixing ring 12 is used to support the winding drive mechanism, and the fixing ring 12 is nested around the outer periphery of the winding ring 11 so that the fixing ring 12 and the winding ring 11 are coaxially arranged.

[0106] Optionally, the supply unit 10 is disposed on the winding member and rotates with the rotation of the winding member;

[0107] Through the cooperation of the supply unit 10 and the winding unit, the optical fiber cladding 14 supplied by the supply unit 10 can be wound around the outer periphery of each of the gathered optical fibers 8, thereby improving the stability and reliability of the production of the optical fiber array 9 and effectively preventing damage to the optical fiber array 9 during processing and causing defects such as low product yield.
