[0053] In order to more clearly illustrate the technical solutions in the embodiments of the present invention or the prior art, the following will briefly introduce the drawings required for use in the embodiments. Obviously, the drawings described below are only some embodiments of the present invention. For those of ordinary skill in the art, without creative efforts, other drawings can also be obtained based on these drawings.

[0054] When describing the embodiments of the present invention, the orientation or positional relationship expressed by the terms "longitudinal", "transverse", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer" is based on the orientation or positional relationship shown in the relevant drawings. It is only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation. Therefore, the above terms should not be construed as limiting the present invention.

[0055] The present invention will be described in detail below in conjunction with the drawings and specific embodiments. The embodiments cannot be elaborated here one by one, but the embodiments of the present invention are not limited to the following embodiments.

[0056] Such as Figure 1As shown, according to an embodiment of the present invention, a device for parallel arrangement of micron-diameter filament fibers of the present invention includes: a support structure 1, and a clamping structure 2 mounted on the support structure 1 for arranging fiber filaments; wherein, the support structure 1 is provided with a plurality of parallel guide rails 11; the clamping structure 2 is correspondingly supported on the upper side of the guide rails 11 one by one. Thus, regular clamping of the fiber filaments can be achieved through the provided clamping structure 2 for preparing corresponding fiber dry yarns; wherein, the interval between adjacent guide rails 11 can be set according to the size of the fiber dry yarn to be actually prepared, which will not be elaborated here. In this embodiment, there are two guide rails 11, and correspondingly, there are also two clamping structures 2 for corresponding setting with the guide rails 11. Of course, in other setting methods, by arranging more guide rails 11 and corresponding clamping structures 2 side by side, the laying range can be expanded, thereby fully improving the flexibility of use of the present invention.

[0057] Combined with Figure 1 and Figure 2 As shown, in this embodiment, the clamping structure 2 includes: an elastic matrix 21 that can be elastically stretched; wherein, a clamping groove 211 for arranging fiber filaments is provided on the upper side of the elastic matrix 21; the extending direction of the clamping groove 211 is perpendicular to the length direction of the elastic matrix 21. Thus, for the convenience of arranging fiber filaments, the clamping groove 211 has an opening on the upper side of the elastic matrix 21 for installing and limiting the single filament; further, for the convenience of arranging fiber filaments, both opposite ends of the clamping groove 211 also form openings on the opposite sides of the elastic matrix 21, so as to ensure the reliable arrangement of fiber filaments. In this embodiment, when the elastic matrix 21 is at its free length, the interval between adjacent clamping grooves 211 is the interval distance between fibers in the fiber dry yarn to be prepared. Further, to ensure the parallelism between adjacent fiber filaments, the parallelism error between adjacent clamping grooves 211 is at the micron level (such as less than 10 μm), thereby effectively ensuring the arrangement accuracy required during the preparation process.

[0058] In this embodiment, one end of the elastic matrix 21 is connected to one end of the guide rail 11, and the other end can be stretched and moved along the guide rail 11; thus, by applying a force to the stretchable end of the elastic matrix 21, a corresponding elongation can be generated along the guide rail 11, thereby making it easier to arrange corresponding fiber filaments on the elastic matrix 21. Furthermore, when the elastic matrix 21 is stretched, the opening of the clamping groove 211 increases to facilitate the arrangement of fiber filaments (see Figure 3 and Figure 4 ), and when the elastic matrix 21 returns to its free length, the clamping groove 211 elastically recovers to clamp and fix the arranged fiber filaments (see Figure 5 ).

[0059] In this embodiment, the clamping groove 211 can be set to have a rectangular cross-sectional shape (see Figure 2 ), trapezoidal, rhombic, circular, triangular (see Figure 7 ); among them, the position with the largest dimension of the clamping groove 211 is set to match the radial dimension of the arranged single fiber filament. Thus, reliable clamping of the single fiber filament can be achieved when the clamping groove 211 returns to its initial state.

[0060] In this embodiment, the sides of the clamping groove 211 that clamp the single fiber filament on opposite sides can be set to be flat, and the flatness error between the two flat surfaces is less than 1 μm, and the parallelism error between the two flat surfaces is also in the micron level (such as less than 10 μm). Thus, reliable clamping of the single fiber filament with a small diameter can be achieved. Of course, in different embodiments, wavy protrusions that can be mutually misaligned and engaged can be further provided on the sides of the clamping groove 211 on opposite sides. Thus, when clamping the single fiber filament, further reliable restriction of the single fiber filament can be achieved based on the mutually matching and engaged wavy protrusions; among them, the wavy protrusions can be set as rectangular wavy protrusions, triangular wavy protrusions, trapezoidal wavy protrusions, etc., and their setting methods can be selected according to actual needs and will not be elaborated here.

[0061] As Figure 6 shown, according to an embodiment of the present invention, the elastic matrix 21 satisfies: the length of the elastic matrix 21 when stretched is 5 to 10 times the free length of the elastic matrix 21.

[0062] Through the above settings, when the length of the elastic matrix 21 when stretched is within the range of 5 to 10 times the free length, the elongation range of the elastic matrix 21 can be effectively increased, so that the stretching length of the elastic matrix 21 can be more flexibly controlled, so that the opening of the clamping groove 211 is flexibly controllable, thus conveniently realizing the arrangement of single fiber filaments of different sizes, and effectively ensuring the use flexibility and applicability of the present invention.

[0063] As Figure 6 shown, according to an embodiment of the present invention, the elastic matrix 21 is a columnar structure with a regular cross-section. In this embodiment, the elastic matrix 21 adopts a columnar structure with a flat upper side. Thus, it is convenient to set the clamping groove 211 on the upper side of the elastic matrix 21, which is more beneficial to improving the positioning accuracy and processing accuracy of the clamping groove 211. In this embodiment, the cross-sectional shape of the elastic matrix 21 can be set to be rectangular. Thus, the length of the clamping groove 211 can be adapted to the width of the elastic matrix 21, thereby providing a guarantee for ensuring that the clamping groove 211 has sufficient support length and realizing reliable and stable support for the fiber filaments.

[0064] Combined with Figure 1 、 Figure 3and Figure 5 As shown in Figure 5 , according to an embodiment of the present invention, the clamping structure 2 further includes: a first base fixing member 22 and a second base fixing member 23 disposed at opposite ends of the elastic base body 21; wherein, the first base fixing member 22 and the second base fixing member 23 are respectively fixedly connected to the ends of the elastic base body 21, and the first base fixing member 22 and the second base fixing member 23 are coaxially disposed with the elastic base body 21; in this embodiment, the first base fixing member 22 and the second base fixing member 23 can both be set as plate-shaped structural members, and they are adhesively bonded to achieve reliable fixation with the ends of the elastic base body 21. Thus, it is ensured that the first base fixing member 22 and the second base fixing member 23 are respectively tightly and reliably connected to the elastic base body 21 to achieve stability during its repeated use.

[0065] In this embodiment, a first connection structure for detachably connecting with the end of the guide rail 11 is disposed on the side of the first base fixing member 22 away from the elastic base body 21; a second connection structure is disposed on the side of the second base fixing member 23 away from the elastic base body 21. Through the provided first connection structure and second connection structure, the disassembly and assembly between the clamping structure 2 and other structures can be conveniently realized, greatly improving the flexibility of use of the present invention, and enabling it to be correspondingly replaced according to fiber dry yarns of different sizes.

[0066] Combined Figure 1 、 Figure 3 and Figure 5 As shown in Figure 1 , Figure 3 and Figure 5 , according to an embodiment of the present invention, along the length direction of the elastic base body 21, the end face error of opposite ends of the first base fixing member 22 is less than 1 μm, and the parallelism error of the end faces of opposite ends of the first base fixing member 22 is at the micron level (such as less than 10 μm), the end face error of opposite ends of the second base fixing member 23 is less than 1 μm, and the parallelism error of the end faces of opposite ends of the second base fixing member 23 is at the micron level (such as less than 10 μm).

[0067] Through the above settings, the accuracy of the positioning and installation surfaces of the first base fixing member 22 and the second base fixing member 23 is effectively ensured, and the adhesive tightness between the first base fixing member 22 and the second base fixing member 23 and the end faces of the elastic base body 21 can be fully ensured, which is particularly beneficial for eliminating possible voids at the bonding positions. In addition, through the above settings, it is more beneficial to accurately control the stretching length of the elastic base body 21 while further ensuring the connection accuracy.

[0068] Combined Figure 1 、 Figure 3 and Figure 5As shown, according to an embodiment of the present invention, a fixing seat 111 for connecting the first base fixing member 22 is provided at one end of the guide rail 11, and a control dial 112 for connecting the second base fixing member 23 and adjustable in position is provided on the guide rail 11; wherein, the fixing seat 111 and the clamping structure 2 are on the same side of the guide rail 11, so that the fixing seat 111 faces the first base fixing member 22, thereby facilitating the connection between the fixing seat 111 and the first base fixing member 22; specifically, the fixing seat 111 is provided with a first fixing structure corresponding to the first connection structure; wherein, the first fixing structure is a through hole, the first connection structure is a threaded hole, and the fixing seat 111 and the first base fixing member 22 are screwed and connected based on a threaded connector passing through the first fixing structure and the first connection structure.

[0069] As Figure 8 shown, in this embodiment, the control dial 112 is slidably connected to the guide rail 11; wherein, the control dial 112 is arranged opposite to the second base fixing member 23 to facilitate the connection with the second base fixing member 23; correspondingly, the control dial 112 is provided with a second fixing structure corresponding to the second connection structure, wherein, the second fixing structure is a through hole, the second connection structure is a threaded hole, thus, the control dial 112 and the second base fixing member 23 are screwed and connected based on a threaded connector passing through the second fixing structure and the second connection structure.

[0070] Further, to facilitate the positioning of the control dial 112 after it moves into place, a position locking member corresponding to the guide rail 11 can be provided on the control dial 112. In this embodiment, the control dial 112 is integrally in a plate-like structure, and its sliding connection with the guide rail 11 is achieved by sleeving. Specifically, a sliding through hole matching the guide rail 11 is provided on the control dial 112, and further, the control dial 112 can be sleeved on the guide rail 11, wherein, the sliding through hole on the control dial 112 and the guide rail 11 slide in a clearance fit manner. In this embodiment, the sliding through hole is below the second fixing structure.

[0071] In this embodiment, the position locking member is arranged corresponding to the sliding through hole, wherein, a threaded hole penetrating the control dial 112 can be provided on the side wall of the sliding through hole, correspondingly, the position locking member can adopt a threaded connector, and further, it can abut against or disengage from the guide rail 11 by screwing with the threaded hole to lock or unlock the position of the control dial 112.

[0072] In this embodiment, the threaded hole is provided on the side of the control paddle 112 facing away from the other guide rail 11; thus, it is convenient to operate the provided position locking member, thereby improving the usability of the present invention. In another embodiment, the threaded hole is provided on the side of the control paddle 112 facing the other guide rail 11; thus, the position locking members of the control paddles 112 on two adjacent guide rails 11 can be made to face each other. As a result, by connecting a control link or other structures between the opposing position locking members, the synchronous locking and unlocking of the two opposing control paddles 112 can be achieved by driving the control link, greatly solving the problem of synchronous locking and unlocking of the two spaced-apart control paddles 112, effectively ensuring their synchronous performance and improving the speed of synchronous operation, which is more beneficial for ensuring the fiber arrangement effect of the present invention.

[0073] Combined with Figure 1 、 Figure 3 and Figure 5 As shown, according to an embodiment of the present invention, the flatness error of the plane on the side of the fixed seat 111 facing the first base fixing member 22 is less than 1 μm, and the parallelism error of the side surfaces on the opposite sides of the fixed seat 111 is at the micron level (such as less than 10 μm); the flatness error of the plane on the side of the control paddle 112 facing the second base fixing member 23 is less than 1 μm, and the parallelism error of the side surfaces on the opposite sides of the control paddle 112 is at the micron level (such as less than 10 μm).

[0074] Through the above settings, the fitting accuracy between the fixed seat 111 and the first base fixing member 22, and the fitting accuracy between the control paddle 112 and the second base fixing member 23 are effectively ensured, which is more beneficial for improving the elongation control accuracy of the present invention.

[0075] Combined with Figure 1 、 Figure 3 and Figure 5 As shown, according to an embodiment of the present invention, the support structure 1 further includes: a connecting beam 12; wherein, the connecting beam 12 is provided at the opposite ends of the guide rail 11 respectively for fixing adjacent guide rails 11; thus, the connecting beam 12 and the guide rail 11 are fixedly formed into a frame structure, such as a square, to maintain the reliable stability of the structure. In this embodiment, the connecting beam 12, the guide rail 11, and the fixed seat 111 are integrally formed, thereby enabling the overall processing and forming of the support structure 1, facilitating the ensuring of the forming accuracy of the overall structure, and being more beneficial for ensuring the precision of the prepared fiber dry yarn.

[0076] Furthermore, along the length direction of the guide rail 11, scales for marking the position of the control paddle 112 are provided on the side surface of the guide rail 11, effectively ensuring the synchronous elongation accuracy of multiple elastic bases 21 and being more beneficial for improving the forming accuracy of the present invention.

[0077] Combined Figure 1 、 Figure 3 and Figure 5 As shown, according to an embodiment of the present invention, the clamping structure 2 can realize the stretching of the elastic matrix 21 by manually driving the second matrix fixing member 23 to move along the guide rail 11. Of course, the controlled stretching of the elastic matrix 21 can also be realized by setting an electric drive on the guide rail 11 and connecting it to the second matrix fixing member 23; wherein, the electric drive adopted is a linear drive device.

[0078] Combined Figure 1 、 Figure 3 and Figure 5 As shown, according to an embodiment of the present invention, the present invention provides an arrangement method using the aforementioned micron-diameter filament fiber parallel arrangement device, including the following steps:

[0079] S1. Take a fiber single filament of a preset length from the pre-prepared fiber bundle, and connect weights of the same weight to both ends of the fiber single filament; in this embodiment, the preset length of the taken fiber single filament can be set between 400 mm and 500 mm; thus, weights of the same mass can be connected to the opposite ends of the fiber single filament respectively, so that the weights at the opposite ends of the fiber single filament are balanced when arranged. In this embodiment, the end of the fiber single filament and the weight are fixed to each other by bonding to ensure reliable connection. In this embodiment, the selection criterion for the weight is: when the fiber single filament can be straightened, the mass of the weight should be as small as possible to avoid damage to the fiber single filament and to avoid the influence of the total mass of all weights on the retraction of the elastic matrix 21, which can effectively ensure the service performance of the elastic matrix 21.

[0080] S2. Adjust the control flap 112 provided on the guide rail 11 to a preset position, and lock the position of the control flap 112 on the guide rail 11 based on the position locking member; wherein, the scale provided on the guide rail 11 is used to confirm that each elastic matrix 21 is stretched equally in length to ensure consistency among them.

[0081] S3. Connect the fixing seat 111 at the end of the guide rail 11 and the first matrix fixing member 22 at the end of the elastic matrix 21 with a threaded connector, and connect the control flap 112 on the guide rail 11 and the second matrix fixing member 23 at the end of the elastic matrix 21 with a threaded connector to realize the stretching of the elastic matrix 21; in this embodiment, the fixing seat 111 and the first matrix fixing member 22 can be abutted against each other under the action of the threaded connector to ensure the accurate positioning of the installation position of the end of the elastic matrix 21; correspondingly, the control flap 112 and the second matrix fixing member 23 are abutted against each other under the action of the threaded connector to ensure the accurate control of the stretching length of the elastic matrix 21 by the control flap 112.

[0082] S4. Place the fiber monofilaments adhered with heavy objects in the corresponding clamping grooves 211 in sequence. And after the fiber monofilaments are arranged to the set number, release all the control levers 112 simultaneously to enable the elastic matrix 21 to return to its free length so as to fix the fiber monofilaments in the clamping grooves 211;

[0083] S5. Fix all the fiber monofilaments by using tape or drop glue without changing the spacing between the fiber monofilaments. Wherein, when there is only one fiber monofilament arranged in each clamping groove 211, the formed fiber dry yarn is a single-layer fiber dry yarn with a thickness consistent with the diameter of the fiber monofilament. Of course, in different setting methods, different numbers of fiber monofilaments can be arranged in each clamping groove 211 to realize the preparation of fiber dry yarns with different thicknesses and layers.

[0084] S6. Cut the fiber monofilaments at the edges to complete the preparation of the fiber dry yarn.
