Description

Technical Field

[0001] The invention relates to the technical field of optical fiber jumper manufacturing, and in particular to a multi-core optical fiber fan-in fan-out jumper manufacturing system and method. Background Art

[0002] Fiber optic patch cords are mainly used to connect two or more communication devices and build a short-distance, high-speed signal transmission link between the two. With its high-speed transmission advantage, fiber optic patch cords play an important role in scenarios such as data centers and enterprise LANs.

[0003] For example, the equipment and method for manufacturing optical fiber jumpers disclosed in Chinese patent CN117148511A, although the selected end of the optical fiber cable is stripped by a stripping device to make it an exposed fiber end, and then the connector of the optical fiber jumper is sleeved and bonded to the exposed fiber end of the optical fiber cable by an assembly device, thereby realizing automatic stripping and automatic assembly of the connector and the optical fiber cable, but ignores the adjustment problem between the line spacing during the manufacturing process, resulting in the non-adjustable spacing, and there are defects such as low efficiency of the manufacturing process and poor adaptive adjustment ability.

[0004] In addition, the prior art also has the following defects:

[0005] 1. Traditional manufacturing methods use laser cutting and chemical etching to process the fiber end face. Laser cutting may cause heat-affected zones, damage the fiber core, and reduce optical performance. Chemical etching is difficult to control accurately and may erode the fiber core, resulting in increased geometric errors on the fiber end face.

[0006] 2. In the fan-in and fan-out process of multi-core optical fibers, the arrangement of optical fibers requires precise control of the fiber spacing and alignment. Currently, manual arrangement or mechanical limit devices are mostly used. This method has the following problems: low precision, large fiber arrangement error, and difficulty in meeting the requirements of high-density jumpers. The process is cumbersome and inefficient, making it difficult to achieve automation.

[0007] 3. Simple mechanical docking and bonding technology is often used in the process of docking the optical fiber end face with the base. The misalignment of the optical fiber and the base leads to optical signal loss. The bonding strength is insufficient, and the connection performance deteriorates during long-term use.

[0008] The present invention is made to solve the common problems in the art, such as non-adjustable line spacing, poor stripping ability of the protective layer at the connection end, low assembly intelligence, and inability to evaluate the assembly process. Summary of the invention

[0059] Wherein, the optical fiber adsorption unit is arranged above the transportation path of at least two of the optical fiber cores.

[0060] Specifically, the optical fiber adsorption module, the arrangement module, the end surface processing module, and the base docking module are all arranged on the frame 8.

[0061] The multi-core fiber fan-in and fan-out jumper manufacturing system also includes a central processing unit, which is respectively controlled and connected to the fiber absorption module, arrangement module, end face processing module, base docking module, and process evaluation module, and based on the central processing unit, the fiber absorption module, arrangement module, end face processing module, base docking module, and process evaluation module are centrally controlled to improve the reliability and safety of the entire system for jumper manufacturing.

[0062] The optical fiber adsorption unit comprises a support plate and an adsorption member, wherein the support plate is used to support the adsorption member, and the adsorption member 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 part, and the other end of the adsorption pipe is connected to the adsorption nozzle 4.

[0064] The adsorption parts are respectively arranged in at least two separation grooves 5 .

[0065] In this embodiment, the number of the dividing grooves 5 provided on the dividing plate 2 matches the number of the optical fiber cores processed or manufactured, and those skilled in the art can adjust it according to the type of optical fiber actually produced.

[0066] The lifting and adjusting unit includes a stand, a lifting rod 29, a lifting drive mechanism, and a lifting detection member. The stand is arranged above the transportation path of the optical fiber core. One end of the lifting rod 29 is connected to the lifting drive mechanism to form a lifting part. The stand is arranged on the frame 8. The stand is provided with an action chamber 30. The lifting part is arranged in the action chamber 30. The other end of the lifting rod 29 extends toward a side away from the lifting part. The lifting detection member is arranged on the lifting rod 29, and the telescopic amount of the lifting rod 29 is detected to obtain the lifting height of the lifting rod 29.

[0067] The action chamber 30 is formed by being recessed downward along the upper end surface of the stand.

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

[0069] In this embodiment, the end face processing modules are symmetrically arranged on the placement path of the optical fiber cores, and preferably, are arranged on the inner walls on both sides of the separation groove 5.

[0070] Optionally, the end surface processing module includes a blade processing unit, a supporting unit and a sliding scraping unit, wherein the blade processing unit is arranged on the sliding scraping unit and cuts the peripheral packaging of at least two optical fiber cores, the sliding scraping unit adjusts the positions of the blade processing unit and the supporting unit to slide along the length direction of at least two optical fiber cores, and the supporting 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 seat 12, an adjustment drive mechanism 18, a connecting rod 16, an adjustment seat 17, an identification probe 19, and an angle marking member 20. The fixed seat 12 is provided with an adjustment cavity 15, and hidden cavities 39 are arranged on the inner walls on 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 hinged portion. The adjustment drive mechanism 18 is arranged on one side of the hinged portion 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 arranged on the adjustment seat 17 and rotates with the rotation of the adjustment seat 17. At least two angle intersection marking members are arranged on the bottom wall of the hidden cavity 39 and are arranged toward the rotation path of the identification probe 19.

[0073] When the adjustment seat 17 is rotating, the identification probe 19 collects the marking number of the angle marking member 20, so as to control the rotation angle.

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

[0075] Different positions correspond to unique marking numbers. For example, the marking number of 30° is different from the marking number of 60°, and both have unique marking identifiers.

[0076] In this embodiment, the adjustment drive mechanism 18 adjusts the steering angle of the connecting rod 16 so that the cutting blade 14 is turned. At the same time, a suitable cutting angle is selected for optical fiber cores of different circumferences, thereby stripping the outer skin of the optical fiber core, thereby 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 rotation gear on the connecting rod 16 to rotate, and drives the adjustment seat 17 to rotate. At this time, the identification probe 19 collects the mark number of the angle marker 20, so as to compare the current mark number with the required mark number. If the two are consistent, the central processing unit controls the rotation drive mechanism to stop driving the driving gear 9 to rotate. On the contrary, if the current mark number is compared with the required mark number, if the two are inconsistent, the central processing unit controls the rotation drive mechanism to continue to drive the driving gear 9 to rotate until the two are consistent.

[0079] In this embodiment, the blade processing unit is disposed on the sliding scraping unit and slides along with the sliding scraping unit, thereby cutting the outer skin 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 (eg Fig. 9 , Fig.10 As shown), and the corresponding cutting blade 14 is selected for different optical fiber cores.

[0082] The abutment rod 13 is configured as a retractable structure, and realizes a retractable action under the drive of the abutment driving mechanism, and adjusts the position of the fixing seat 12, so that the cutting blade 14 is close to the outer packaging of the optical fiber core and pierces 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 arranged on both sides of at least two cable core conveying paths. The sliding seat 11 is slidingly connected to the sliding rail 10. The sliding drive mechanism is arranged 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 abutment 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, driven by the sliding seat 11, is transported toward one end of the optical fiber core, so that the outer packaging and the optical fiber core body are separated to expose the connection ends 3 of at least two optical fiber cores.

[0090] When the spacing of the optical fiber cores is adjusted, the spacing of the two adjacent optical fiber cores is compared and the adjustment of the adjustment airbag 6 on the corresponding side is triggered, so that the spacing of the current optical fiber core and the adjacent optical fiber core is balanced, and the spacing of the optical fiber cores is balanced, such as Figure 4 shown.

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

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

[0098] At the same time, the resolution of the acquisition probe 21 needs to be set in combination with specific usage conditions.

[0099] Optionally, the evaluation unit obtains image data of the distribution state of at least two adjacent optical fiber cores and performs preprocessing to obtain edge pixel points of the at least two adjacent optical fiber cores and a set of centerline points of the two optical fiber cores determined by the edge pixel points of the at least two optical 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 optical fiber cores according to the following formula:

[0100]

[0101] Where n is the number of point pairs on the center line of the optical fiber core, d i is the Euclidean distance between the i-th pair of corresponding points, κ i is the local curvature of the i-th point, μ d is the average distance between all point pairs, μ κ is the average local curvature of all points;

[0102] Among them, the Euclidean distance d between the corresponding points of the i-th pair is i Calculated according to the following formula:

[0103]

[0104] In the formula, (x 1i ,y 1i ) is the coordinate of the i-th point on the center line of the first optical fiber core, (x 2i ,y 2i ) is the coordinate of the i-th point on the center line of the second optical fiber core, and the coordinate x 1i and 1iThe coordinates x and y respectively represent the horizontal and vertical positions of the i-th point on the center line of the first optical fiber core in the two-dimensional plane. 2i and 2i They respectively represent the lateral and longitudinal positions of the coordinate point of the i-th point on the center line of the first optical fiber core in the two-dimensional plane, and the coordinate point is obtained from the image of the optical fiber core through image processing (such as center line extraction algorithm).

[0105] The local curvature κ for the i-th point i Calculated according to the following formula:

[0106]

[0107] In the formula, (x i ,y i ) is the coordinate of the center line of the optical fiber core at point i, (x i+1 ,y i+1 ) is the coordinate of the center line of the optical fiber core at point i+1. |x i+1 y i -x i y i+1 |For(x i ,y i ) and (x i+1 ,y i+1 ) on the two-dimensional plane, the denominator is the slope difference of the point (x i ,y i ) and (x i+1 ,y i+1 ) to the cube of the Euclidean distance.

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

[0115] If the spacing state index DSI of two adjacent optical fiber cores is less than or equal to the set monitoring threshold THO, it means that the spacing between the two adjacent optical fiber cores meets the system requirements;
