Description

Technical Field

[0001] This invention relates to the field of optical fiber panel manufacturing technology, and in particular to a design method for composite absorber wires for optical fiber panels, the composite absorber wires and their preparation methods and applications. Background Technology

[0002] In current fiber optic panel manufacturing, the gaps between the rods need to be filled with light-absorbing and light-filling fibers during the panel fabrication stage. By adjusting the quantity and position of these two materials, the requirements for fiber optic panel grid, contrast, and transmittance are met. However, this process has significant drawbacks: firstly, the need to insert the two materials sequentially makes the operation cumbersome and reduces personnel time efficiency; secondly, the strict requirements for their placement make them prone to errors, leading to high rework rates and high product defect rates, severely impacting production schedules and cost control. Summary of the Invention

[0003] The main objective of this invention is to provide a design method for composite absorber wires for optical fiber panels, the composite absorber wires themselves, their preparation methods, and their applications. The technical problem to be solved is how to design a composite absorber wire that integrates absorber material and filler material, so that it can simplify the wire insertion process, accurately match the cross-sectional ratio requirements, significantly improve production efficiency, reduce the defect rate, and ensure that the core performance of the optical fiber panel, such as grid, contrast, and transmittance, continues to meet the standards, thus making it more suitable for practical use.

[0062] This invention proposes a design method for composite absorber wires for optical fiber panels, the composite absorber wire itself, its preparation method, and its application. It first calculates the area ratio A of the absorber wire to the filler wire and the area ratio B of the absorber wire to the monofilament in existing processes, providing precise benchmark parameters for the design of the composite absorber wire and ensuring seamless integration of the new design with the performance requirements of existing processes. Then, by matching the wire arrangement scheme, the area ratio C of the absorber material to the filler material deviates from A by ≤1%, ensuring that the ratio of the two materials in the composite absorber wire meets the core performance requirements of the optical fiber panel's grid, contrast, and transmittance, avoiding product performance failure due to ratio imbalance. Subsequently, by presetting the radial opposite side dimension H0, calculating the total cross-sectional area and ratio D, and adjusting through a closed loop to ensure that the deviation between D and B is ≤1%, the drawing dimensions of the composite absorber wire are precisely controlled, ensuring its compatibility with the monofilament. By integrating the absorber and filler fibers according to the fiber arrangement scheme in the fabrication method of the composite absorber fiber, the two materials that needed to be inserted sequentially in the original process are integrated into a single composite fiber. This eliminates the cumbersome steps of positioning and inserting the two materials separately, reducing the complexity of the operation process and fundamentally avoiding arrangement errors caused by the strict requirements for the positional distribution of the two materials, thereby reducing the probability of rework and the product defect rate. The fiber panel fabrication step of filling the gaps between the fibers inside the primary rod, combined with the precise size design of the composite absorber fiber, further ensures the regularity of the fiber panel structure and improves the mesh qualification rate. The entire technical solution of this invention, through the synergistic effect of precise parameter matching, material integration design, and closed-loop size control, simplifies the fiber insertion operation process while achieving high efficiency and stability in the production process. It reduces the operation time of a single person, increases the output per unit time, and continuously ensures that the core performance of the fiber panel meets the standards, achieving simultaneous optimization of production efficiency and product quality.

[0071] To further illustrate the technical means and effects adopted by the present invention to achieve its intended purpose, the following, in conjunction with the appendix and preferred embodiments, details the design method, preparation method, and application of a composite absorber wire for optical fiber panels according to the present invention, as well as its specific implementation methods and effects. In the following description, different "embodiments" or "embodiments" do not necessarily refer to the same embodiment. Furthermore, the results of one or more embodiments can be combined in any suitable manner. These embodiments are provided to make the invention thorough and complete, and to fully express the scope of the invention to those skilled in the art. It should be noted that, unless otherwise specifically stated, the relative arrangement of components and steps, material composition, numerical expressions, and values ​​described in these embodiments should be interpreted as merely exemplary and not as limiting.

[0072] This invention proposes a design method for composite absorber wires for optical fiber panels, which includes the following steps:

[0073] First, calculate the area ratio A of the absorbing filament to the filling filament and the area ratio B of the absorbing filament to the monofilament in the radial cross section under the existing process of the optical fiber panel.

[0074] In some specific embodiments of the present invention, the calculation methods for the area ratio A of the absorbing wire to the filler wire and the area ratio B of the absorbing wire to the monofilament in the radial cross section are as follows:

[0075] 1)

[0076] 2)

[0077] Where x is the diameter of the absorbent, m is the number of absorbent strands, y is the diameter of the filler, n is the number of filler strands, j is the number of monofilaments, and k is the diameter of the monofilament.

[0078] The above formula is applicable to scenarios where the absorbent and filler materials are round filaments. The specific calculation formula can be adjusted according to the actual situation.

[0079] Then, a matching fiber arrangement scheme is determined based on parameter A; in some specific embodiments of the present invention, the preferred fiber arrangement scheme includes at least the shape of the composite absorbent fiber, the arrangement pattern of the composite absorbent fiber, the quantity of absorbent material, the quantity of filler material, and the area ratio C of absorbent material to filler material; the matching criterion is that the deviation between parameter C and A is ≤1%.

[0080] In some specific embodiments of the present invention, the preferred shapes of the composite absorber wires include equilateral triangles, squares, and regular hexagons. The reason for this design is that the above three shapes all have the characteristics of stable geometric structure, compact arrangement, and precise matching of the gaps between the primary wires of the optical fiber panel. Furthermore, through a unified proportional matching and closed-loop size adjustment logic, the integrated design of the absorber and filler can be achieved, ultimately achieving the invention's objective of simplifying wire insertion operations and improving production efficiency.

[0081] In some specific embodiments of the present invention, the composite absorbent fibers are equilateral triangles; the fiber arrangement scheme is as follows: the arrangement pattern of the composite absorbent fibers corresponds to a triangular rod structure, the number of base bars of the triangular rods is a, a≥2 and is an integer; the total number of composite absorbent fibers = a(1+a) / 2; the number of absorbent fibers e = [mx 2 a(a+1)] / [2mx 2 +2ny 2 The area ratio of absorbent material to filler material is C = 2e / (a). 2 -2e+a). In some specific embodiments, the triangular bar arrangement structure of the equilateral triangular composite absorber wire is shown in the attached figure. Figure 1 As shown, black represents absorbent material and white represents filler material. A schematic arrangement is detailed in Table 1 below:

[0082] Table 1 Arrangement Parameters of Equilateral Triangular Rod Composite Absorbing Wire

[0083]

[0084] In some specific embodiments of the present invention, the composite absorbent wires are square in shape; the wire arrangement scheme is as follows: the arrangement pattern of the composite absorbent wires corresponds to a square bar structure, the number of wires on each side of the square bar is a, a≥2 and is an integer; the total number of composite absorbent wires = a 2 ; Absorbent quantity e = [mx 2 a 2 ] / [mx 2 +ny 2 The area ratio of absorbent material to filler material, C = e / (a 2 -e). See Table 2 below for illustrative arrangement schemes:

[0085] Table 2 Arrangement Parameters of Quadrilateral Rod Composite Absorbing Filaments

[0086]

[0087] In some specific embodiments of the present invention, the composite absorbent wires are hexagonal in shape; the wire arrangement scheme is as follows: the arrangement pattern of the composite absorbent wires corresponds to a regular hexagonal bar structure, the number of wires on each side of the regular hexagonal bar is 'a', a ≥ 2 and is an integer; the total number of composite absorbent wires = 3a 2 -3a+1; Absorbent quantity e= [mx 2 (3a 2 -3a+1)] / [mx 2 +ny 2 The area ratio of absorbent material to filler material is C = e / (3a). 2 -3a+1-e). A schematic arrangement is shown in Table 3 below:

[0088] Table 3 Arrangement parameters of hexagonal rod composite absorber wire

[0089]

[0090] In practical applications, the area ratio A of the absorbing wire to the filling wire in the radial section of the optical fiber panel is first calculated based on the existing process. Then, the technical solution with the area ratio C closest to the area ratio A is selected from the preset absorber and filling material arrangement scheme library. The closer A and C are, the better. The preferred parameter C has a deviation of ≤1% from A to ensure that the original performance indicators of the optical fiber panel can still be maintained after the composite absorbing wire is replaced with the filling wire and the absorbing wire.

[0091] The arrangement schemes listed in Tables 1, 2, and 3 above are only illustrative and not the only fixed ones; in the actual arrangement process, the number of absorbent strands, the number of filler strands, and the arrangement pattern can be adjusted adaptively, and the area ratio C corresponding to different arrangement schemes will also change accordingly.

[0092] The next step is to obtain the radial side dimension H of the drawn composite absorbent yarn through iterative adjustment. Specifically, the radial side dimension H0 of the drawn composite absorbent yarn is first preset based on theoretical calculations or practical experience. Then, based on the radial side dimension and the shape of the composite absorbent yarn, the total cross-sectional area of ​​the drawn composite absorbent yarn, the total cross-sectional area of ​​the absorbent material, the total cross-sectional area of ​​the single filament, and the ratio D of the total cross-sectional area of ​​the absorbent material to the total cross-sectional area of ​​the single filament are calculated. Then, the parameters D and B are compared. If the difference between the two is >1%, the preset value of the radial side dimension is adjusted, and the parameter D is recalculated based on the new parameters. If the difference between the two is ≤1%, the last preset value of the radial side dimension is taken as the radial side dimension H of the drawn composite absorbent yarn.

[0093] In some specific embodiments of the present invention, the theoretical calculation formula for the radial opposite side dimension H0 of the triangular bar structure is as follows:

[0094] 3).

[0095] In some specific embodiments of the present invention, the total cross-sectional area S after the triangular rod structure composite absorbent wire is drawn is... 复合三角 The formula is as follows:

[0096] 4)

[0097] Total cross-sectional area S of absorbent material 吸收 = C / (C+1)×S 复合三角 ;

[0098] Total cross-sectional area S of a single filament 单丝 = j×π(k / 2) 2 ;

[0099] Ratio D = S 吸收 / S 单丝 .

[0100] In some specific embodiments of the present invention, the theoretical calculation formula for the radial opposite side dimension H0 of the square bar structure is as follows:

[0101] 5).

[0102] In some specific embodiments of the present invention, the total cross-sectional area S after the tetragonal bar structure composite absorbent wire is drawn is... 复合正方 =(m+n)H0 2 ;

[0103] Total cross-sectional area S of absorbent material 吸收 = C / (C+1)×S 复合正方 ;

[0104] Total cross-sectional area S of a single filament 单丝 = j×π(k / 2) 2 ;

[0105] Ratio D = S 吸收 / S 单丝 .

[0106] In some specific embodiments of the present invention, the theoretical calculation formula for the radial opposite side dimension H0 of the regular hexagonal bar structure is as follows:

[0107] 6).

[0108] In some specific embodiments of the present invention, the total cross-sectional area S after the hexagonal rod structure composite absorbent wire is drawn is... 复合正六边 The formula is as follows:

[0109] 7)

[0110] Total cross-sectional area S of absorbent material 吸收 = C / (C+1)×S复合正六边 ;

[0111] Total cross-sectional area S of a single filament 单丝 = j×π(k / 2) 2 ;

[0112] Ratio D = S 吸收 / S 单丝 .

[0113] Finally, the radial side dimension H of the composite absorbent yarn after it has been drawn is combined with the shape and arrangement pattern of the composite absorbent yarn to form the design scheme of the composite absorbent yarn.

[0114] This invention also proposes a method for preparing composite absorbent fibers, which includes the following steps:

[0115] First, the design scheme of the composite absorbent wire is determined according to the aforementioned design method; including the shape of the composite absorbent wire, the arrangement pattern of the absorbent material and filler material in the composite absorbent wire, and the radial side dimension H of the composite absorbent wire after it is drawn.

[0116] Then, the absorbent and filling fibers are integrated and arranged according to the pattern in the design scheme.

[0117] Finally, the integrated filaments are drawn, with the drawing temperature controlled within the middle range of the melting points of the two materials, and the drawing speed at 0.5-2 m / min, so that the radial side dimension of the drawn composite absorber filament is H, thus obtaining the composite absorber filament. The above drawing process can adopt the conventional optical fiber drawing process in this technical field, and this invention does not make specific limitations thereto.

[0118] This invention also proposes a composite absorber wire, which is prepared according to the aforementioned preparation method. The composite absorber wire integrates absorber and filler, and the radial cross-sectional shape is preferably an equilateral triangle, square or regular hexagon, with a radial opposite side dimension of H, and satisfies: the area ratio of absorber to filler is C≈A, and the ratio of the total cross-sectional area of ​​absorber to the total cross-sectional area of ​​single wire is D≈B. Here, "approximately equal" means that the closer the parameters A and C, and parameters B and D are, the better the effect. In order to ensure the performance indicators of the final prepared optical fiber panel, it is preferred that the difference between the two is within 1%.

[0119] This invention also proposes a method for fabricating an optical fiber panel, which includes the following steps:

[0120] First, a primary rod is formed by arranging the fiber optic panel in a conventional manner; then, the gaps between the fibers inside the primary rod are filled with the aforementioned composite absorber fibers of matching diameter, and then the fiber optic panel fabrication process is completed according to conventional procedures.

[0121] This invention also proposes an optical fiber panel, which is prepared according to the aforementioned method. The optical fiber panel, after testing, exhibits a mesh qualification rate ≥99%, contrast ratio ≤1%, and transmittance ≥52%, with all performance indicators superior to existing products.

Some non-essential improvements and adjustments made to the present invention by those skilled in the art based on the above description of the present invention still fall within the scope of protection of the present invention.
