DETAILED DESCRIPTION

[0059] To make the purpose, technical solutions, and advantages of the embodiments of this application more clear, the technical solutions in the embodiments of this application will be clearly and completely described below in conjunction with the drawings in the embodiments of this application. Obviously, the described embodiments are part of the embodiments of this application, not all of the embodiments. Based on the embodiments in this application, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of this application.

[0060] It should be understood that:

[0061] The optical fiber proof test is a non-destructive method that subjects each section of a long optical fiber to a predetermined tensile stress or strain. Fiber with a certain proof strength is unlikely to be damaged when subjected to an external force equal to the proof stress, so the proof strength is also called the proof strength.

[0062] Optical fiber screening and rewinding is an important process in the optical fiber production process and is also a labor-intensive process.

[0063] Fiber screening and rewinding mainly realize four functions:

[0064] 1. According to the data of the drawing process recorder, discard the defective products in the drawing process, such as bare fiber bubbles, unqualified bare fiber diameter and coating diameter, etc.

[0065] 2. According to customer needs, 500km to 2000km of continuous optical fiber can be divided into 25km or 50km lengths as required.

[0066] 3. According to national standards, the optical fiber is subjected to a 2% deformation test for 2 seconds to verify the strength of the optical fiber and ensure the service life of the optical fiber.

[0067] 4. Arrange the optical fibers in an orderly manner with appropriate tightness to facilitate the effective and accurate inspection of the optical fiber attenuation level and ensure that the fibers will not be broken when the next coloring process is released.

[0068] The optical fiber arrangement process requires manual inspection to ensure that there are no abnormalities in the optical fiber arrangement.

[0069] Main issues:

[0070] (1) The screening process is a labor-intensive process. It requires people to calculate the length of the screening and rewinding according to the defective points. If the optical fiber is broken, the length needs to be recalculated manually. If the optical fiber is broken, it also requires people to spend a lot of time to rehang the fiber. When one person operates multiple screening machines, they need to wait in line.

[0071] (2) The take-up end is a small reel, which needs to be manually changed every 20 minutes or so, which is a lot of work. When a person encounters multiple devices that need to change reels, it causes downtime and waiting.

[0072] Traditional screening machines do not have the automatic loading and unloading functions at the pay-off end and the automatic loading and unloading functions at the take-up end. The wire drawing and winding barrel at the pay-off end needs to be placed manually. The optical fiber reel is very heavy and inconvenient to operate.

[0073] (3) The quality of optical fiber arrangement needs to be manually observed regularly to confirm the arrangement quality and make interventions.

[0074] We will explain the above questions one by one.

[0075] On the first aspect, the embodiments of the present application provide a fiber optic screening device, which can solve the problem in the related art that when a fiber optic screening machine breaks during screening, it takes a lot of time for manual labor to re-hang the fiber.

[0076] See also Figures 1-4 As shown, in a first aspect, an optical fiber screening device comprises:

[0077] The traction wheels of the pay-out traction assembly 2 and the take-up traction assembly 3 on the working surface of the cabinet 1 are distributed according to a preset optical fiber traction trajectory; some of the traction wheels are used for traction guidance, and some are used for generating tension; the pay-out traction assembly 2 and the take-up traction assembly 3 are existing structures;

[0078] The sprocket assembly includes a plurality of sprockets 4 distributed in the working surface, and the plurality of sprockets 4 are connected in series end to end through a chain 5; a portion of the sprockets 4 is eccentrically connected to the traction wheel, and one of the other sprockets 4 located in the second installation area is connected to the first drive motor; a fiber clamp 6 is installed on a certain link of the chain 5; Figure 3 and Figure 4 Schematic diagram of the chain 5 and optical fiber pulling trajectory distribution;

[0079] The fiber hanging device 8 is located within the work surface near the end of the preset fiber traction trajectory. Upon identifying the fiber clamp 6, the fiber hanging device 8 is used to deliver the fiber support to the take-up reel fiber clamping mechanism 7 of the optical fiber screening equipment. The space within the cabinet 1 is used to house the traction assembly 2, the take-up traction assembly 3, the drive components of the fiber hanging device 8, and the first drive motor. The end of the preset fiber traction trajectory is relative to the starting end, that is, from the take-up end.

[0080] Since the traction wheels of the pay-off traction assembly 2 and the take-up traction assembly 3 of the cabinet 1 are distributed according to the preset optical fiber traction trajectory; the multiple sprockets 4 of the sprocket assembly are connected in series end to end through the chain 5; one part of the sprockets 4 is eccentrically connected to the traction wheel, and one of the other part of the sprockets 4 is connected to the first drive motor; an optical fiber clamp 6 is installed on a certain link of the chain 5; in this way, a long chain 5 is installed on the sprocket 4, and the chain 5 is driven by the first drive motor and circulates on the sprockets 4 of all traction wheels to ensure that the movement trajectory of the chain 5 and the optical fiber traction trajectory are coincident, and the sprocket 4 does not rotate with the traction wheel during screening, and the optical fiber clamp 6 is installed at On one link of the chain 5, it moves with the chain 5, so that when a fiber break occurs, the sprocket assembly is used to send the optical fiber clamp 6 to the vicinity of the pay-out traction assembly 2; then the optical fiber head is made and connected to the optical fiber clamp 6; the sprocket assembly is used to drive the optical fiber clamp 6 to move along the optical fiber traction trajectory to the fiber hanging device 8, and then after the fiber hanging device 8 recognizes that the optical fiber clamp 6 has moved to a position near the take-up reel fiber clamping mechanism 7, the first drive motor is controlled to stop rotating, and then the optical fiber top support is sent to the take-up reel fiber clamping mechanism 7 of the optical fiber screening equipment. The above does not require manual re-traction along the optical fiber traction trajectory, which solves the problem of manual labor spending a lot of time on re-hanging the fiber.

[0081] In some preferred embodiments, reference Figure 8 As shown, the fiber hanging device 8 is explained in detail, specifically:

[0082] The working surface includes a first installation area and a second installation area. The first installation area is provided with a line-releasing traction assembly 2, and the second installation area is provided with a line-retrieving traction assembly 3. The sprockets 4 are distributed in the first installation area and the second installation area.

[0083] The fiber hanging device 8 is located in the second installation area. The fiber hanging device 8 includes a fiber clamp identification assembly 800 and a rotary fiber feeding assembly 801. The rotary fiber feeding assembly 801 is located above the sprocket 4 connected to the first drive motor and is used to deliver the fiber support to the take-up reel fiber clamping mechanism 7 after the fiber clamp identification assembly 800 identifies the fiber clamp 6. The sprocket 4 connected to the first drive motor is located below the take-up reel fiber clamping mechanism 7. The fiber clamp identification assembly 800 can be a visual sensor.

[0084] The rotating fiber feeding assembly 801 includes a guide rod 80101 , one end of which is connected to a guide wheel 80102 , and the other end is connected to a second drive motor 80103 ; the second drive motor 80103 is used to drive the guide rod 80101 to rotate with its output shaft as the center.

[0085] Through the above arrangement, when the optical fiber clamp 6 guides the optical fiber to the bottom of the take-up reel clamping mechanism 7, the chain 5 stops rotating, and the second drive motor 80103 drives the guide rod 80101 to rotate, so that the guide wheel 80102 contacts the optical fiber. As it continues to rotate, the optical fiber is fed into the take-up reel clamping mechanism 7, thereby completing automatic traction and automatic hanging to imitate the manual hanging action, replacing manual hanging and improving efficiency. The hanging process of the hanging device 8 is as follows: Figures 8 to 10 As shown, the movement process of chain 5 is Figure 3 shown.

[0086] In some preferred embodiments, reference Figure 6 、 Figure 7 As shown, the structure of the optical fiber clamp 6 is described in detail:

[0087] The optical fiber clamp 6 includes a chain link connecting block 600, and the chain link connecting block 600 is provided with two spaced-apart petals 601 in the receiving groove. One petal 601 is attached to and fixedly connected to the inner wall of the receiving groove, and the other petal 601 is connected to the inner wall of the receiving groove through a spring; the two petals 601 extend to the outside of the receiving groove.

[0088] The above realizes the connection between the optical fiber clamp 6 and the chain 5 and achieves the normally closed clamping effect.

[0089] Furthermore, the above needs to re-make the optical fiber head after the fiber is broken. In order to cancel the manual operation process, there are the following settings, refer to Figure 6 、 Figure 7 As shown:

[0090] A first through hole is provided on the flap 601 of the two flaps 601 that is in contact with and fixedly connected to the inner wall of the receiving groove; a second through hole 602 that communicates with the first through hole and the receiving groove is provided on the outer side of the link connecting block 600;

[0091] The optical fiber screening device further includes a fiber clamping and cutting mechanism 9 located within the first installation area; the fiber clamping and cutting mechanism 9 includes a base plate 900, on which are disposed a first horizontal telescopic member 901, a second horizontal telescopic member 902, and a vertical lifting member 903, which are sequentially spaced apart; a top post for extending into the first and second through holes 602 is disposed at the telescopic end of the first horizontal telescopic member 901; a cutter is disposed at the telescopic end of the second horizontal telescopic member 902; and a V-shaped block is disposed at the top of the vertical lifting member 903.

[0092] Two parallel, spaced baffles 904 are also provided on the base plate 900. One baffle 904 is spaced correspondingly to the first horizontal telescopic member 901, and the other baffle 904 is spaced correspondingly to the second horizontal telescopic member 902, thereby forming a space for the chain 5 and the fiber clamp 6 to pass through. The baffles 904 are used to form a cutting plate for cutting.

[0093] The fiber optic clamp 6 has a spring inside to keep the clamp in a closed state by default. When the clamp needs to be opened, the first horizontal telescopic member 901 is used to press against one of the flaps 601 that does not have the first through hole to open it.

[0094] When the fiber clamp 6 needs to enter the predetermined position to clamp the optical fiber, the vertical lifting member 903 first lifts up, allowing the fiber clamp to enter the optical fiber path. Then, the first horizontal telescopic member 901 opens the fiber clamp 6, and the vertical lifting member 903 drops, allowing the optical fiber to fall into the fiber clamp 6. After the optical fiber falls into the fiber clamp 6, the first horizontal telescopic member 901 retracts, and the fiber clamp 6 clamps the optical fiber. The second horizontal telescopic member 902 actuates to cut the optical fiber. At this point, the optical fiber head is completed and clamped by the fiber clamp 6. The above automatic fiber hanging operation can then be carried out without interference, thereby speeding up the production of the optical fiber head.

[0095] In some preferred embodiments, reference Figure 5 , introduce the structure of the pay-off traction assembly 2 and the take-up traction assembly 3, and their relationship with the sprocket 4:

[0096] The pay-off traction assembly 2 and the take-up traction assembly 3 have the same structure, forming a screening system; the screening system also includes a PLC controller located in the cabinet 1;

[0097] The pay-off traction assembly 2 includes a mounting plate 200 and a plurality of traction wheels; one of the traction wheels is rotatably connected to the mounting plate 200 via a rotating shaft, and a third drive motor 201 is connected to the end of the rotating shaft away from the traction wheel; a sprocket 4 is rotatably provided on the rotating shaft and located between the traction wheel and the mounting plate 200; the diameter of the sprocket 4 is slightly larger than the traction wheel; by default, the fiber clamp 6 is in a closed state, and the fiber clamp 6 moves between the traction wheels with the chain 5. Since the sprocket 4 is slightly larger than the traction wheel, the fiber clamp 6 will not interfere with the screening system when it moves, and the fiber clamp is on the chain.

[0098] Two pressing wheels 202 are further provided on the mounting plate 200 , and the two pressing wheels 202 are provided with a pressing belt 203 that contacts the outer ring of the traction wheel.

[0099] The speed difference between the payout and takeup pulleys causes elastic deformation of the optical fiber, which in turn generates tension on the fiber. The tension coefficient is a functional function of the fiber tension. The tension control model of the PLC controller is as follows:

[0100] V1=k*T0*V0

[0101] ⊿V=V2-V1

[0102] ⊿T=T-T0

[0103] ⊿V=k*⊿T*V0

[0104] V2=V1+k*⊿T*V0

[0105] Where V1 is the set line speed of the traction wheel for taking up the line, V2 is the actual line speed of the traction wheel for taking up the line, T0 is the set tension, T is the actual tension, V0 is the line speed of the traction wheel for paying out the line, and k is the tension coefficient;

[0106] The calculation model of the remaining length and remaining time of the PLC controller screening operation is as follows:

[0107] Acceleration time: t1 = V / a1

[0108] Deceleration time: t2 = V / a2

[0109] Acceleration running length: L1=1 / 2*V*t1

[0110] Deceleration running length: L2=1 / 2*V*t2

[0111] Uniform running length: L3 = L-L1-L2

[0112] Remaining length: L4 = L - L0

[0113] Uniform speed running time: t3 = L3 / V

[0114] Total running time: t = t1 + t2 + t3

[0115] The remaining running time is divided into three situations:

[0116] When the remaining length is not greater than the deceleration length: t4=(√(2*L4))V0

[0117] When the remaining length is greater than the acceleration length and not greater than the sum of the deceleration length and the uniform speed length, t4 = (L4-L2) / V+t2

[0118] When the remaining length is greater than the sum of the deceleration length and the uniform speed length, t4 = (V / V0-1)*t1+t3+t2

[0119] Where V is the screening set line speed, V0 is the current line speed, a1 is the set acceleration slope, a2 is the user-set deceleration slope.

[0120] The internal model of the PLC controller includes a real-time calculation model for the coil diameter. Assuming that the linear speed from the winding shaft to the corresponding traction wheel is equal, and that the linear speed and coil diameter remain unchanged in a very short period of time, then:

[0121] R = V / (n*π).

[0122] Where R is the actual diameter of the winding shaft, V is the linear velocity, and n is the rotational speed. The actual diameter can be used to control the speed of the rewinding and unwinding.

[0123] The internal model of the PLC controller includes a speed control model. Using the above-mentioned real-time coil diameter calculation method, the coil diameter is calculated and updated at regular intervals. Before the coil diameter is updated, it is assumed that the coil diameter remains unchanged. In this case:

[0124] n=V / (R*π)+k⊿θ

[0125] Where n is the rotational speed, R is the actual winding diameter of the winding shaft, V is the linear velocity, R is the current winding diameter of the winding shaft, k is the dancer wheel proportional coefficient, and ⊿θ is the deviation between the dancer wheel's actual angle and its equilibrium value. When the dancer wheel angle deviation is positive, the winding shaft speed increases; otherwise, it decreases. The dancer wheel's position is maintained in equilibrium by speed control. The dancer wheel is a traction wheel.

[0126] The above introduces the screening principle and process of the screening system.

[0127] In some preferred embodiments, to address the high workload of manually changing reels every 20 minutes or so, the small reels at the take-up end are a major issue. This can cause downtime and waiting when a single operator needs to change reels across multiple devices. Conventional screening machines lack automatic reel loading and unloading functions for the pay-off end and the take-up end. The drawbar barrel on the pay-off end requires manual placement, and the heavy fiber reels make operation inconvenient. The following features are implemented:

[0128] For the settings of the online end, refer to Figure 1 、 Figure 12 and Figure 13 As shown:

[0129] The optical fiber screening device further includes a wire-paying end barrel device 10 located outside the cabinet 1 and corresponding to the first installation area;

[0130] The fiber optic disc barrel device 10 includes a fiber optic disc clamping and rotating assembly and a fiber optic disc translation assembly; the fiber optic disc clamping and rotating assembly has an adjustable clamping space; the fiber optic disc translation assembly is used to put the fiber optic disc into the clamping space;

[0131] The optical fiber reel clamping and rotating assembly includes a first rack platform 1000, a first support base 1001, and a second support base 1002. The first support base 1001 is close to the first installation area and fixedly connected to the first rack platform 1000. The second support base 1002 is away from the first installation area and connected to the first rack platform 1000 via a first guide rail 1003. A first translation cylinder 1004 is provided on the first rack platform 1000. The output end of the first translation cylinder 1004 is connected to the second support base 1002 to change the distance between the first support base 1001 and the second support base 1002.

[0132] A pay-off spindle 1005 is provided on each of the first support base 1001 and the second support base 1002; a fourth drive motor 1006 is provided on one end of the pay-off spindle 1005 of the first support base 1001, and a fiber optic disc connection disc 1007 is provided on the other end;

[0133] The optical fiber reel translation assembly includes a second guide rail 1008 and a second translation cylinder 10010, which are parallel to each other. The length of the second guide rail 1008 is perpendicular to the length of the first guide rail 1003. The second guide rail 1008 is located below the pay-off spindle 1005 and is mounted on the bottom plate of the second support base 1002. A slide 1009 is provided on the second guide rail 1008. The second translation cylinder 10010 is connected to the slide 1009 to drive the slide 1009 to move on the second guide rail 1008.

[0134] The slide 1009 is provided with a fiber optic disc positioning groove and a positioning sensor 10011.

[0135] The payoff end uses a wire-free solution, and the payoff motor is fixed. An inclined guide wheel is installed on the first mounting area, 2 meters away from the payoff barrel. The inclined guide wheel adopts a deep-grooved U-shaped design, with the groove facing the tangent direction of the fiber optic reel on the slide 1009 when installed.

[0136] The movement process of the fiber optic disc is as follows: first place the fiber optic disc on the slide 1009, and the fiber optic disc positioning placement slot and positioning sensor 10011 determine whether it exists; under the action of the second translation cylinder 10010, the slide 1009 moves to between the first support seat 1001 and the second support seat 1002, that is, the middle hole of the fiber optic disc is coaxial with the two pay-off spindles 1005; then the first translation cylinder 1004 moves the second support seat 1002 to allow the pay-off spindle 1005 to enter the middle hole of the fiber optic disc, and then the fiber optic disc connecting disc 1007 is connected to the fiber optic disc; use the fourth drive motor 1006 to drive the fiber optic disc connecting disc 1007 and the fiber optic disc to rotate to realize the rotation of the fiber optic disc and perform the pay-off operation.

[0137] Regarding the receiving end, refer to Figure 1 、 Figure 14 、 Figure 15 and Figure 8 As shown:

[0138] The optical fiber screening equipment further includes a second rack platform 11 located outside the cabinet 1 and corresponding to the second installation area; the second rack platform 11 is provided with a loading and unloading mechanism 12, a lifting tray mechanism 13, a take-up reel fiber clamping mechanism 7, a labeling mechanism 14, and a wire arrangement closed-loop control device 15;

[0139] The lifting tray mechanism 13 and the wire arrangement closed-loop control device 15 are located on the same straight line, and the straight line is perpendicular to the second installation area;

[0140] The lifting tray mechanism 13 has a flap 1300 for placing the optical fiber disk; the loading and unloading mechanism 12 has an upper inclined plate 1200 and a lower inclined plate 1201, and the lower inclined plate 1201 is located below the flap 1300; the upper inclined plate 1200 and the lower inclined plate 1201 are arranged perpendicular to the straight line;

[0141] A column is provided on the second frame platform 11, and a guide rail bracket 16 is provided on the column; a take-up reel fiber clamping mechanism 7 is movably set on the guide rail bracket 16; in the moving direction of the take-up reel fiber clamping mechanism 7, the labeling mechanism 14 and the lifting tray mechanism 13 are arranged at intervals, wherein the labeling mechanism 14 is away from the first installation area, and the lifting tray mechanism 13 is close to the first installation area; the bottom of the take-up reel fiber clamping mechanism 7 is located between the labeling mechanism 14 and the lifting tray mechanism 13; in the moving direction of the take-up reel fiber clamping mechanism 7, the loading and unloading mechanism 12 and the labeling mechanism 14 are located on the same side.

[0142] The take-up reel fiber clamping mechanism 7 includes a horizontal cylinder 700 provided on the guide rail bracket 16, the output end of the horizontal cylinder 700 is connected to a moving block slidably provided on the guide rail bracket 16; a vertical cylinder 706 is provided on the moving block, and a connecting plate 701 is provided at the bottom of the vertical cylinder 706;

[0143] Connecting plate 701 is equipped with a front clamping jaw 702 and a rear clamping jaw 703, with a pneumatic cutter 704 located between them. Front clamping jaw 702 is connected to connecting plate 701 via an inclined telescopic rod 705, which extends and retracts perpendicular to the direction of optical fiber movement. The structure of front clamping jaw 702 and rear clamping jaw 703 is not specifically limited; any existing structure is acceptable as long as they can clamp and release the optical fiber.

[0144] The lifting tray mechanism 13 includes a vertical plate 1301 and a rectangular frame 1302. The vertical plate 1301 is provided with a lifting cylinder 1303 that drives the rectangular frame 1302 to move up and down. A flap member 1300 is provided within the rectangular frame 1302. The flap member 1300 includes a rectangular plate, a round rod is provided on the rectangular plate, and the round rod is connected to a fifth drive motor. The rectangular plate is located in the space enclosed by the rectangular frame 1302, and the fifth drive motor is connected to the rectangular frame 1302. The rectangular plate is provided with a fiber optic tray positioning groove.

[0145] The loading and unloading mechanism 12 includes a frame 1202, on which an upper inclined plate 1200 and a lower inclined plate 1201 are provided; the lower inclined plate 1201 is located below the rectangular frame 1302; the upper inclined plate 1200 is installed with a front stop cylinder and a rear stop cylinder spaced along its length, and the output ends of the front stop cylinder and the rear stop cylinder are both provided with a stop rod.

[0146] In the above, the fiber optic reel's own weight enables it to roll on the upper inclined plate 1200 and the lower inclined plate 1201. The upper inclined plate 1200 is equipped with a front and rear stop cylinder spaced along its length. The output ends of the front and rear stop cylinders are each equipped with a stop rod, which extends to ensure that only one reel is loaded at a time. At this point, the lifting cylinder 1303 of the lifting tray mechanism 13 should be raised to the end of the upper inclined plate 1200 and lowered after receiving the fiber optic reel. After the fiber optic reel is fully wound, the fifth drive motor drives the rectangular plate downward via the round rod, causing the fiber optic reel to fall onto the lower inclined plate 1201, thus achieving automatic loading and unloading.

[0147] In addition, after the optical fiber is hung in the fiber clamping mechanism 7 of the take-up reel, the front clamping jaw 702 and the rear clamping jaw 703 clamp the optical fiber, and the pneumatic cutter 704 cuts off the fiber head; then it moves to the right, the telescopic rod 705 extends, and in addition, since the connecting plate 701 can be moved by the vertical cylinder 706 and the horizontal cylinder 700, the fiber head is extended to the labeling position; the labeling position is the position where the optical fiber enters the notch of the optical fiber reel, which is convenient for pasting the optical fiber head; the fiber reel is a double-notch reel, in which the notch is oblique, and the angle between the oblique notch and the plane of the side plate of the fiber reel is acute, and the double notches are two optical fiber channels for the outer reel and the inner reel respectively.

[0148] The labeling mechanism 14 then grips the label paper with its suction head. Simultaneously, the fiber reel is moved to the labeling position by the closed-loop control device 15. The fiber clamping mechanism then shifts right and descends. The labeling mechanism 14 moves to the labeling position, attaching the fiber head to the reel. The labeling mechanism 14 then resets, and the take-up reel's fiber clamping mechanism 7 resets, allowing the take-up end to enter the reel.

[0149] The above-mentioned labeling mechanism 14 and wire arrangement closed-loop control device 15 are existing devices and will not be introduced in detail here; the labeling mechanism 14 generally includes a translation cylinder, a vacuum suction head, a rotary cylinder, and a labeling machine. When receiving a labeling command, the labeling machine will send a label paper to the vacuum suction head, and the suction head will suck the label paper. The rotating cylinder rotates 90 degrees counterclockwise to make the label plane vertical, and the translation cylinder moves to the left to stick the label to the optical fiber disk, thereby fixing the optical fiber head; the wire arrangement closed-loop control device 15 includes a lifting tray mechanism 13 that can clamp and drive the rotation, and can move in the axial direction of the optical fiber disk.

[0150] It should be understood that the fiber optic reel can be a payout reel for laying out optical fibers or a reel for winding up optical fibers, and is here collectively referred to as a fiber optic reel. The above configuration solves the problem of not having automatic loading and unloading functions on the payout end and the reeling end, requiring manual placement of the wire drawing and winding barrel on the payout end by the screening machine, and the fiber optic reel being heavy and inconvenient to operate.

[0151] In some preferred embodiments, to solve the problem that the optical fiber arrangement quality requires manual regular observation, confirmation, and intervention:

[0152] The wire arrangement closed-loop control device 15 is provided with a high-speed camera, which is connected to a machine vision processing module and a compensation module;

[0153] The high-speed camera is used to detect the arrangement of the optical fiber disc on the lifting tray mechanism 13 in real time;

[0154] The machine vision processing module is used to detect the fiber boundary slope in the local area according to the detection information of the high-speed camera, and then detect the fiber stacking and recessed areas according to the fiber boundary slope; the compensation module is used to perform real-time compensation on the wire arrangement closed-loop control device 15 according to the detected fiber stacking and recessed areas.

[0155] The internal model of the compensation module includes a precision cable arrangement compensation calculation model. During the take-up and winding process, individual fiber spool variations, fixed deviations, and other interfering factors can cause deviations in the start and end positions of the take-up and arrangement, causing the fiber to pile up or sag at both ends of the spool. This pile-up and sag manifests as localized changes in the reel diameter, which in turn causes changes in the take-up axis speed, leading to oscillation of the take-up dancer. By detecting and calculating the angular deviation of the take-up dancer's oscillation, compensation is applied to the position values of the two endpoints of the cable arrangement. The calculation model is as follows:

[0156] ⊿θ=θ1-θ2

[0157] S=k*i

[0158] Where θ1 is the angle value of the dancing wheel when the real-time position of the spool is close to the endpoint at a certain distance, θ2 is the angle value of the dancing wheel when the real-time position of the spool is away from the endpoint at a certain distance, ⊿θ is the angle deviation value, k is the single compensation length, i is the number of compensations, and S is the actual compensation value.

[0159] Each time the line position completes a U-turn at the endpoint, the angle deviation of the dance wheel is detected and calculated. When ⊿θ is greater than the preset value a, i is incremented by 1; when ⊿θ is less than the preset value b, i is incremented or decremented by 1. This compensates for the deviation of the original line endpoint position.

[0160] The machine vision processing module detects the fiber boundary slope in the local area through binarization, filtering and denoising, Hough transform and other algorithms, thereby detecting the fiber stacking and recessed areas, and performing real-time compensation through the automatic wire arrangement algorithm.

[0161] In a second aspect, a method for optical fiber screening is provided, comprising:

[0162] When a fiber break occurs, the sprocket assembly is used to move the optical fiber clamp 6 to the vicinity of the pay-off traction assembly 2; then the optical fiber head is made and connected to the optical fiber clamp 6;

[0163] The sprocket assembly drives the optical fiber clamp 6 to move along the optical fiber pulling track to the fiber hanging device 8. Then, after the optical fiber clamp 6 is identified by the fiber hanging device 8, the optical fiber top support is sent to the fiber clamping mechanism 7 of the fiber screening equipment.

[0164] The overall process of the optical fiber screening method is:

[0165] S1, the pay-off end is passed upward, and the optical fiber disc is first placed on the slide 1009, and the optical fiber disc positioning placement slot and positioning sensor 10011 determine whether it exists; under the action of the second translation cylinder 10010, the slide 1009 moves to between the first support seat 1001 and the second support seat 1002, that is, the middle hole of the optical fiber disc is coaxial with the two pay-off spindles 1005; then the first translation cylinder 1004 moves the second support seat 1002 to allow the pay-off spindle 1005 to enter the middle hole of the optical fiber disc, and then the optical fiber disc connecting disc 1007 is connected to the optical fiber disc; the fourth drive motor 1006 is used to drive the optical fiber disc connecting disc 1007 and the optical fiber disc to rotate to realize the rotation of the optical fiber disc, and the pay-off operation is performed, and the barrel action is completed.

[0166] S2. When the fiber clamp 6 needs to enter the predetermined position to clamp the optical fiber, the vertical lifting member 903 is first lifted up to allow the fiber clamp to enter the optical fiber path; then the first horizontal telescopic member 901 opens the fiber clamp 6, and the vertical lifting member 903 falls down, allowing the optical fiber to fall into the fiber clamp 6; after the optical fiber falls into the fiber clamp 6, the first horizontal telescopic member 901 retracts, and the fiber clamp 6 clamps the optical fiber; the second horizontal telescopic member 902 is actuated to cut the optical fiber. At this point, the optical fiber head is made and clamped by the fiber clamp 6. Then the chain 5 is controlled to rotate and the screening machine enters the threading mode. The optical fiber clamp 6 carries the optical fiber head along the preset optical fiber traction trajectory and finally reaches the predetermined fiber hanging device 8. The fiber hanging device 8 is started, and the optical fiber clamp 6 guides the optical fiber to move to the bottom of the take-up reel fiber clamping mechanism 7. The chain 5 stops rotating, and the second drive motor 80103 drives the guide rod 80101 to rotate, so that the guide wheel 80102 contacts the optical fiber. As it continues to rotate, the optical fiber is sent into the front clamping jaw 702 and the rear clamping jaw 703 of the take-up reel fiber clamping mechanism 7, and then the pneumatic cutter 704 cuts the optical fiber, and the optical fiber clamp 6 disconnects from the optical fiber. When the chain 5 runs, it is in the standby position. At this point, the fiber head at the take-up end is made.

[0167] S3, the loading and unloading mechanism 12 and the lifting tray mechanism 13 cooperate to load the material, the take-up reel fiber clamping mechanism 7, the labeling mechanism 14, and the wire arrangement closed-loop control device 15 cooperate to stick the optical fiber head to the reel, and the reeling action is completed.

[0168] S4, the screening machine enters the screening mode and enters the tension building stage. The speed difference between the pay-out traction assembly 2 and the take-up traction assembly 3 causes elastic deformation of the optical fiber, thereby generating tension on the optical fiber.

[0169] S5. A high-speed camera is provided on the wire arrangement closed-loop control device 15, which is connected to a machine vision processing module and a compensation module; the high-speed camera is used to detect the wire arrangement status of the optical fiber reel on the lifting tray mechanism 13 in real time; the machine vision processing module is used to detect the fiber boundary slope in the local area according to the detection information of the high-speed camera, and then detect the fiber stacking and recessed areas according to the fiber boundary slope; the compensation module is used to compensate the wire arrangement closed-loop control device 15 in real time according to the detected fiber stacking and recessed areas.

[0170] The above implementation enables automatic loading and unloading of barrels at the pay-off end, automatic reel change at the take-up end, and automatic fiber hanging after fiber breakage. At the same time, it has an efficient automatic wire arrangement algorithm, which greatly realizes the automation and intelligence of the screening machine and greatly improves the production efficiency of the screening process.
