Description

Technical Field

[0001] This invention relates to the field of fiber optic patch cord manufacturing technology, and in particular to a manufacturing system and method for multi-core fiber optic fan-in and fan-out patch cords. Background Technology

[0002] Fiber optic patch cords are primarily used to connect two or more devices that need to communicate, establishing a short-distance, high-speed signal transmission link between them. Due to their high-speed transmission advantages, fiber optic patch cords play a vital role in scenarios such as data centers and enterprise local area networks.

[0003] For example, the equipment and method for manufacturing fiber optic patch cords disclosed in Chinese patent CN117148511A, although it strips the selected end of the optical transmission cable with a stripping device to expose the fiber, and then uses an assembly device to attach the connector of the fiber optic patch cord to the exposed fiber end of the optical transmission cable, thereby achieving automatic stripping and automatic assembly of the connector and optical transmission cable, neglects the problem of adjusting the spacing between the lines during the manufacturing process, resulting in the spacing being unadjustable and having defects such as low manufacturing efficiency and poor adaptive adjustment capability.

[0004] In addition, the existing technology also has the following drawbacks:

[0005] 1. Traditional manufacturing methods use laser cutting and chemical etching to process the fiber end face. Laser cutting can cause heat-affected zones, damaging the fiber core and reducing optical performance. Chemical etching is difficult to control precisely and may erode the fiber core, leading to increased geometric errors at the fiber end face.

[0006] 2. In the fan-in and fan-out process of multi-core optical fibers, the fiber arrangement requires precise control of fiber spacing and alignment. Currently, most methods employ manual arrangement or mechanical limiting devices, which have the following problems: low accuracy, large fiber arrangement errors, and difficulty in meeting the requirements of high-density patch cords. The process is cumbersome and inefficient, making automation difficult.

[0007] 3. During the connection process between the fiber optic end face and the substrate, simple mechanical connection and bonding techniques are often used. Misalignment between the fiber and the substrate leads to optical signal loss. Insufficient bonding strength results in decreased connection performance over long-term use.

[0008] This invention was developed to address common problems in the field, such as the inability to adjust line spacing, poor peeling ability of protective layers at connection ends, low level of assembly intelligence, and inability to evaluate the assembly process. Summary of the Invention

[0009] The purpose of this invention is to address the shortcomings of current methods by proposing a manufacturing system and method for multi-core fiber fan-in and fan-out patch cords.

[0010] To overcome the shortcomings of the prior art, the present invention adopts the following technical solution:

[0011] A multi-core fiber fan-in / fan-out patch cord manufacturing system is disclosed. The system includes a fiber adsorption module, an arrangement module, an end-face processing module, a base docking module, and a process evaluation module. The fiber adsorption module adsorbs at least two fiber cores. The arrangement module adjusts the spacing between the adsorbed at least two fiber cores. The end-face processing module processes the arranged at least two fiber cores to expose their connection ends. The base docking module docks the connection ends of the at least two fiber cores with the processing base. The process evaluation module collects the arrangement status data from the fiber adsorption module, evaluates the arrangement status based on the status data to form an evaluation result, and triggers the arrangement module to adjust the spacing between the at least two fiber cores.

[0012] The fiber adsorption module shown includes a fiber adsorption unit and a lifting adjustment unit. The lifting adjustment unit adjusts the fiber adsorption unit, and the fiber adsorption unit adsorbs at least two fiber cores.

[0013] The optical fiber adsorption unit is disposed above the transport path of at least two optical fiber cores.

[0014] Optionally, the end face processing module includes a blade processing unit and a sliding scraping unit. The blade processing unit is disposed on the sliding scraping unit and cuts the outer peripheral packaging of at least two optical fiber cores. The sliding scraping unit adjusts the position of the blade processing unit to slide along the length direction of at least two optical fiber cores.

[0015] The blade processing unit includes a cutting blade and an angle adjustment component. The cutting blade is used to cut the outer packaging of the optical fiber core, and the angle adjustment component adjusts the cutting contact angle between the cutting blade and the optical fiber core.

[0019] Optionally, the process evaluation module includes an acquisition unit, an evaluation unit, and a spacing control unit. The acquisition unit acquires spacing images of at least two fiber cores. The evaluation unit evaluates the spacing status of the at least two fiber cores based on the spacing images to form an evaluation result. The spacing control unit triggers spacing adjustment of the arrangement module based on the evaluation result.

[0020] Optionally, the acquisition unit is disposed above the arrangement module to acquire image data of the distribution status of at least two optical fiber cores. The acquisition unit includes an acquisition probe and a data storage device. The acquisition probe acquires image data of the distribution status of at least two adjacent optical fiber cores, and the data storage device stores the image data of the distribution status of at least two adjacent optical fiber cores acquired by the acquisition probe.

[0021] Optionally, the evaluation unit acquires image data of the distribution state of at least two adjacent fiber cores and performs preprocessing to obtain the edge pixels of the at least two adjacent fiber cores and the set of centerline points of the two fiber cores determined by the edge pixels of the at least two fiber cores, respectively, C1={(x 1i ,y 1i )} n i＝1 and C2={(x 2j ,y 2j )} n j＝1 And calculate the spacing state index (DSI) of two adjacent fiber cores according to the following formula:

[0022]

[0023] In the formula, n is the number of point pairs on the centerline of the fiber core, and d i Let κ be the Euclidean distance between corresponding points in the i-th pair. i Let μ be the local curvature at point i. d μ is the average distance between all point pairs. κ This represents the average local curvature at all points;

[0024] If the spacing status index (DSI) of two adjacent fiber cores exceeds the set monitoring threshold (THO), the spacing control unit is triggered to control the arrangement module and adjust the spacing between the two adjacent fibers.

[0025] In addition, the present invention also provides a method for manufacturing a multi-core fiber optic fan-in / fan-out patch cord, the method comprising the following steps:

[0026] S1. At least two supplied optical fiber cores are adsorbed by the optical fiber adsorption module and lifted to the original transport surface.

[0027] S2. The end face processing module peels off the outer packaging of at least two adsorbed optical fiber cores to expose the connection ends of at least two optical fiber cores.

[0030] S5. The evaluation unit evaluates the spacing status of at least two fiber cores based on the acquired spacing image to form an evaluation result.

[0031] S6. The evaluation unit compares the evaluation result with the monitoring threshold THO set by the system. If the qualification condition is not met, it jumps to step S7; otherwise, it jumps to step S8.

[0032] S7. Trigger the arrangement module to adjust the spacing between at least two fiber cores, and repeat steps S4 to S6.

[0033] S8. At least two fiber cores with exposed connection ends are docked with the processing base using the base docking module.

[0034] Optionally, the multi-core fiber fan-in / fan-out patch cord manufacturing method further includes: in step S2, the end face processing module adjusts the cutting angle according to the type of at least two fiber cores, and peels off the outer packaging of one end of at least two fiber cores to expose the connection end of at least two fiber cores.

[0035] Optionally, the method for manufacturing multi-core fiber fan-in and fan-out patch cords further includes: in step S5, analyzing the spacing images of at least two adjacent fiber cores in sequence, and triggering the arrangement module set at the corresponding position to adjust the spacing of the two adjacent fiber cores.

[0036] The beneficial effects achieved by this invention are:

[0037] 1. By cooperating with the spacing adjustment unit of the arrangement module and the real-time detection unit of the process evaluation module, the arrangement spacing of the fiber cores can be dynamically adjusted, eliminating spacing deviations and ensuring that the entire system has the advantages of high arrangement accuracy and good processing consistency.

[0038] 2. By working together with the fiber optic adsorption module and the process evaluation module, the accuracy of the fiber optic adsorption position can be detected and corrected in real time, ensuring that the entire system has the advantages of high initial adsorption accuracy and small subsequent processing errors.

[0039] 3.

Detailed Implementation

[0056] The following specific embodiments illustrate the implementation of the present invention. Those skilled in the art can understand the advantages and effects of the present invention from the content disclosed in this specification. The present invention can be implemented or applied through other different specific embodiments, and various details in this specification can also be modified and changed based on different viewpoints and applications without departing from the spirit of the present invention. Furthermore, the accompanying drawings of the present invention are for simple illustrative purposes only and are not depictions of actual dimensions; this is stated beforehand. 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.

[0057] Example 1: 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 and Figure 13As shown, this embodiment provides a multi-core fiber fan-in / fan-out patch cord manufacturing system, including a frame 8. The multi-core fiber fan-in / fan-out patch cord manufacturing system also includes a fiber adsorption module, an arrangement module, an end-face processing module, a base docking module, and a process evaluation module. The fiber adsorption module adsorbs at least two fiber cores. The arrangement module adjusts the spacing between the adsorbed at least two fiber cores. The end-face processing module processes the arranged at least two fiber cores to expose the connection ends 3 of the at least two fiber cores. The base docking module docks the connection ends 3 of the at least two fibers with the processing base 33. The process evaluation module collects the arrangement status data of the fiber adsorption module, evaluates the arrangement status based on the status data to form an evaluation result, and triggers the arrangement module to adjust the spacing between the at least two fibers.

[0058] The fiber adsorption module shown includes a fiber adsorption unit and a lifting adjustment unit. The lifting adjustment unit adjusts the fiber adsorption unit, and the fiber adsorption unit adsorbs at least two fiber cores.

[0059] The optical fiber adsorption unit is disposed above the transport path of at least two optical fiber cores.

[0060] Specifically, the fiber optic adsorption module, the arrangement module, the end face processing module, and the base docking module are all mounted on the frame 8.

[0061] The multi-core fiber fan-in / fan-out patch cord manufacturing system also includes a central processing unit (CPU). The CPU is connected to the fiber adsorption module, the arrangement module, the end-face processing module, the base docking module, and the process evaluation module. The CPU provides centralized control over these modules to improve the reliability and safety of the entire system in patch cord manufacturing.

[0062] The optical fiber adsorption unit includes a support plate and an adsorption component. The support plate is used to support the adsorption component, and the adsorption component adsorbs at least two optical fiber cores.

[0063] The adsorption component includes a partition plate 2, an adsorption nozzle 4, an adsorption pump, and an adsorption pipe. The partition plate 2 is provided with at least two partition grooves 5. One end of the adsorption pipe is connected to the adsorption pump to form an adsorption section, and the other end of the adsorption pipe is connected to the adsorption nozzle 4.

[0064] The adsorption portion is disposed in at least two partition grooves 5.

[0065] In this embodiment, the number of partition slots 5 provided on the partition plate 2 is matched with the number of optical fiber cores processed or manufactured. Those skilled in the art can adjust this according to the actual type of optical fiber produced.

[0066] The lifting adjustment unit includes a stand, a lifting rod 29, a lifting drive mechanism, and a lifting detection component. The stand is positioned above the transport path of the optical fiber core. One end of the lifting rod 29 is driven to connect with the lifting drive mechanism to form a lifting section. The stand is mounted on the frame 8 and has an action cavity 30. The lifting section is located in the action cavity 30. The other end of the lifting rod 29 extends away from the lifting section. The lifting detection component is mounted on the lifting rod 29 and detects the extension and retraction of the lifting rod 29 to obtain the lifting height of the lifting rod 29.

[0067] The action cavity 30 is recessed downward along the upper end of the stand.

[0068] In this embodiment, the lifting adjustment unit drives the adsorption component to contact at least two optical fiber cores on the transport path, and adsorbs at least two optical fiber cores through the adsorption nozzles 4 in at least two of the separation grooves 5. At the same time, after the adsorption nozzles 4 adsorb at least two optical fiber cores, the lifting adjustment unit lifts the optical fiber cores off the original transport path, and triggers the end face processing module to remove the outer packaging (outer wrapping layer) of the optical fiber cores to expose the connection ends 3 of at least two optical fiber cores.

[0069] In this embodiment, the end face processing module is symmetrically arranged on the placement path of the optical fiber core, preferably arranged on the inner walls of both sides of the partition groove 5.

[0070] Optionally, the end-face processing module includes a blade processing unit, a contact unit, and a sliding scraping unit. The blade processing unit is disposed on the sliding scraping unit and cuts the outer peripheral packaging of at least two optical fiber cores. The sliding scraping unit adjusts the positions of the blade processing unit and the contact unit to slide along the length direction of at least two optical fiber cores. The contact unit adjusts the position of the blade processing unit so that the blade processing unit can contact the outer packaging of the optical fiber core.

[0071] The blade processing unit includes a cutting blade 14 and an angle adjustment component. The cutting blade 14 is used to cut the outer packaging of the optical fiber core, and the angle adjustment component adjusts the cutting contact angle between the cutting blade 14 and the optical fiber core.

[0072] The angle adjustment component includes a fixed base 12, an adjustment drive mechanism 18, a connecting rod 16, an adjustment seat 17, an identification probe 19, and angle markers 20. The fixed base 12 has an adjustment cavity 15, and hidden cavities 39 are provided on the inner walls of both sides of the adjustment cavity 15. One end of the connecting rod 16 is connected to the adjustment seat 17, and the other end of the connecting rod 16 is hinged to the bottom wall of the hidden cavity 39 to form a hinge. The adjustment drive mechanism 18 is located on one side of the hinge and meshes with the drive gear 9 nested on the connecting rod 16, so that the adjustment drive mechanism 18 drives the connecting rod 16 to rotate along its own axis. The identification probe 19 is located on the adjustment seat 17 and rotates with the rotation of the adjustment seat 17. At least two angle markers are located on the bottom wall of the hidden cavity 39 and are positioned towards the rotation path of the identification probe 19.

[0073] As the adjustment seat 17 rotates, the identification probe 19 collects the marking number of the angle marker 20, thereby controlling the rotation angle.

[0074] The cutting blade 14 is mounted on the adjusting seat 17 and rotates along with the adjusting seat 17.

[0075] Each position corresponds to a unique marker number. For example, the marker number for 30° and the marker number for 60° are different; both have unique marker identifiers.

[0076] In this embodiment, the adjustment drive mechanism 18 adjusts the turning angle of the connecting rod 16 so that the cutting blade 14 turns. At the same time, a suitable cutting angle is selected for optical fiber cores with different circumferences, thereby stripping the outer sheath of the optical fiber core and exposing the connecting ends 3 of at least two optical fiber cores.

[0077] The specific steering adjustment process includes:

[0078] The rotation drive mechanism drives the rotating gear on the connecting rod 16 to rotate, which in turn rotates the adjusting seat 17. At this time, the identification probe 19 collects the marking number of the angle marker 20 and compares the current marking number with the required marking number. If they match, the central processing unit controls the rotation drive mechanism to stop driving the drive gear 9 to rotate. Conversely, if the current marking number does not match the required marking number, the central processing unit controls the rotation drive mechanism to continue driving the drive gear 9 to rotate until they match.

[0079] In this embodiment, the blade processing unit is disposed on the sliding scraping unit and slides along with the sliding scraping unit to cut the outer sheath of the optical fiber core to peel it off, thereby exposing the connection ends 3 of at least two optical fiber cores.

[0080] In this embodiment, the cutting blade 14 is irregularly serrated (e.g., Figure 9 , Figure 10 As shown), and the cutting blade 14 is selected to match different optical fiber cores.

[0081] The abutting unit includes an abutting rod 13, an abutting driving mechanism, and an abutting detection component. One end of the abutting rod 13 is connected to the outer wall of the fixed base 12, and the other end of the abutting rod 13 is driven to be connected to the abutting driving mechanism to form an abutting part. The abutting part is disposed on the sliding scraping unit, and the abutting detection component detects the extension and retraction length of the abutting rod 13.

[0082] The abutment rod 13 is configured as a telescopic structure and performs telescopic movements under the drive of the abutment driving mechanism, thereby adjusting the position of the fixed seat 12 so that the cutting blade 14 approaches the outer packaging of the optical fiber core and punctures the outer packaging.

[0083] The sliding scraping unit includes a sliding rail 10, a sliding seat 11, and a sliding drive mechanism. The sliding rail 10 is disposed on both sides of the conveying path of at least two cable cores. The sliding seat 11 is slidably connected to the sliding rail 10. The sliding drive mechanism is disposed on the sliding seat 11 and drives the sliding seat 11 to slide along the extension direction of the sliding rail 10.

[0084] Specifically, after the abutting unit adjusts the cutting blade 14 to contact the outer packaging of the optical fiber core, the cutting blade 14 pierces the outer packaging of the optical fiber core and is driven by the sliding seat 11 to move towards one end of the optical fiber core, so that the outer packaging and the optical fiber core body are separated to expose the connection end 3 of at least two optical fiber cores.

[0085] Optionally, the end face processing module is located on one side of the arrangement module (the side away from the adsorption module) and processes at least two fiber cores arranged by the arrangement module to expose the connection ends 3 of at least two fiber cores.

[0086] Optionally, the arrangement module includes a spacing adjustment unit and a support unit, the support unit supporting the spacing adjustment unit, and the spacing adjustment unit adjusting the spacing between at least two optical fibers;

[0087] The support unit includes a support base 7 and at least two adjustment slots disposed on the support base 7, and the spacing adjustment units are respectively disposed in the at least two adjustment slots.

[0088] The support base 7 is disposed on the side of the partition plate 2 near the base docking module;

[0089] The spacing adjustment unit includes an adjustment airbag 6, an adjustment pump, an electronic vent valve, and an air supply pipe. The air supply pipe is connected to the adjustment pump, and the other end of the air supply pipe is connected to the adjustment airbag 6 to form an adjustment section. The adjustment section is respectively disposed on the inner walls of both sides of the adjustment groove. The electronic vent valve is disposed on the adjustment airbag 6 and communicates with the interior of the adjustment airbag 6.

[0090] During the adjustment of the fiber core spacing, the spacing of two adjacent fiber cores is compared, and the corresponding adjustment airbag 6 is triggered to adjust, thereby balancing the spacing of the current fiber core and its adjacent fiber cores. The fiber core spacing is balanced, as shown below. Figure 4 As shown.

[0091] The process evaluation module is positioned above the optical fiber adsorption module and collects image data of two adjacent optical fiber cores from the alignment module.

[0092] By cooperating with the arrangement module and the end-face processing module, the arranged fiber cores can be stably fixed and the connection end face can be accurately exposed, ensuring that the whole system has the advantages of high end-face processing accuracy and low fiber end-face damage rate.

[0093] By combining the fiber adsorption module and the arrangement module, the fiber cores can be precisely adsorbed and arranged at a set interval, ensuring that the entire system has the advantages of high arrangement accuracy and good fiber position consistency.

[0094] Optionally, the process evaluation module includes an acquisition unit, an evaluation unit, and a spacing control unit. The acquisition unit acquires spacing images of at least two fiber cores. The evaluation unit evaluates the spacing status of the at least two fiber cores based on the spacing images to form an evaluation result. The spacing control unit triggers spacing adjustment of the arrangement module based on the evaluation result.

[0095] Optionally, the acquisition unit is disposed above the arrangement module to acquire image data of the distribution status of at least two optical fiber cores. The acquisition unit includes an acquisition probe 21 and a data storage device. The acquisition probe 21 acquires image data of the distribution status of at least two adjacent optical fiber cores, and the data storage device stores the image data of the distribution status of at least two adjacent optical fiber cores acquired by the acquisition probe 21.

[0096] The acquisition unit includes a support rod 31, which is shaped like a "7". One end of the support rod 31 is connected to the side frame of the frame 8, and the other end of the support rod 31 extends out above the arrangement module.

[0097] The acquisition probe 21 extends from one end of the support rod 31 toward the side of the arrangement module to acquire image data of the arrangement module and at least two optical fiber cores.

[0098] Meanwhile, the resolution of the acquisition probe 21 needs to be set according to the specific usage.

[0099] Optionally, the evaluation unit acquires image data of the distribution state of at least two adjacent fiber cores and performs preprocessing to obtain the edge pixels of the at least two adjacent fiber cores and the set of centerline points of the two fiber cores determined by the edge pixels of the at least two fiber cores, respectively, C1={(x 1i ,y 1i )} n i＝1 and C2={(x 2j ,y 2j )} n j＝1 And calculate the spacing state index (DSI) of two adjacent fiber cores according to the following formula:

[0100]

[0101] In the formula, n is the number of point pairs on the centerline of the fiber core, and d i Let κ be the Euclidean distance between corresponding points in the i-th pair. i Let μ be the local curvature at point i. d μ is the average distance between all point pairs. κ This represents the average local curvature at all points;

[0102] Wherein, the Euclidean distance d between corresponding points of the i-th pair i Calculate according to the following formula:

[0103]

[0104] In the formula, (x 1i ,y 1i Let (x) be the coordinates of point i on the center line of the first fiber core. 2i ,y 2i Let x be the coordinates of point i on the center line of the second fiber core. 1i and y 1iThese represent the horizontal and vertical positions of the i-th point on the center line of the first fiber core in a two-dimensional plane, respectively, with coordinates x and x. 2i and y 2i These represent the horizontal and vertical positions of the i-th point on the centerline of the first optical fiber core in a two-dimensional plane, respectively. The coordinates are obtained from the image of the optical fiber core through image processing (such as a centerline extraction algorithm).

[0105] For the local curvature κ at point i i Calculate according to the following formula:

[0106]

[0107] In the formula, (x i ,y i (x) is the coordinate of the fiber core centerline at point i. i+1 ,y i+1 ) represents the coordinates of the fiber core centerline at point i+1. i+1 y i -x i y i+1 |for(x) i ,y i ) and (x i+1 ,y i+1 The difference in slope on the two-dimensional plane, with the denominator being the point (x) i ,y i ) and (x i+1 ,y i+1 The cube of the Euclidean distance.

[0108] For the average distance μ between all point pairs d Calculate according to the following formula:

[0109]

[0110] In the formula, n is the number of point pairs in the set of centerline points of two adjacent optical fibers, which is usually the number of points extracted from the set of centerline points of two optical fiber cores (C1 and C2 are of equal size), d i Let be the Euclidean distance between corresponding points in the i-th pair.

[0111] The local curvature average μ at all points κ Calculate according to the following formula:

[0112]

[0113] In the formula, n is the number of point pairs in the set of centerline points of two adjacent optical fibers, which is usually the number of points extracted from the set of centerline points of two optical fiber cores (C1 and C2 are of equal size), κ i Let be the local curvature at point i.

[0114] If the spacing status index (DSI) of two adjacent fiber cores exceeds the set monitoring threshold (THO), the spacing control unit is triggered to control the arrangement module and adjust the spacing between the two adjacent fibers.

[0115] If the spacing status index (DSI) of two adjacent fiber cores is less than or equal to the set monitoring threshold (THO), it indicates that the spacing between the two adjacent fiber cores meets the system requirements.

[0116] Meanwhile, the monitoring threshold THO is set by the system according to the type of fiber optic patch cord actually produced. This is a technical method well known to those skilled in the art, and therefore will not be described in detail in this embodiment.

[0117] In this embodiment, an example of a set monitoring threshold THO value is provided. Specifically: 1) For high-precision single-mode fiber optic patch cords, the monitoring threshold value is 0.02; 2) For data center multimode fiber optic patch cords, the monitoring threshold value is 0.05; 3) For high-density multi-core fiber optic patch cords (such as 8-core or 16-core), the monitoring threshold value is 0.03; 4) For special-purpose optical fibers (such as sensing optical fibers), the monitoring threshold value is 0.08.

[0118] The spacing control unit will evaluate the assessment results of the acquisition unit and the monitoring threshold THO set by the system, and calculate the spacing adjustment ΔD between two adjacent fiber optic cables:

[0119]

[0120] In the formula, d i d0 is the actual spacing between the i-th pair of adjacent fiber cores, d0 is the target spacing, which is the ideal spacing value set by the system, and n is the number of points between the current fiber core centerline and the centerline of the adjacent fiber core.

[0121] The spacing control unit calculates the airbag inflation volume Δn based on the spacing fine-tuning amount ΔD:

[0122]
