Description

Technical Field

[0001] This invention relates to the field of fiber reinforcement production technology, and more specifically to a fiber reinforcement winding device. Background Technology

[0002] Fiberglass reinforced polymer (FRP) bars are composite reinforcement materials made of high-strength continuous fibers such as glass fiber and basalt fiber as reinforcement and resin as matrix, produced through processes such as pultrusion and winding. Compared with traditional metal steel bars, they have outstanding advantages such as being lightweight, high-strength, corrosion-resistant, and non-magnetic, and have gradually become an important alternative material in harsh environments such as civil engineering, marine structures, and bridge reinforcement. To enhance the bonding performance with concrete, the surface of fiberglass reinforced polymer bars usually needs to be processed with a regular thread structure. This structure can be achieved by spirally winding a polymer tape (winding tape) around the surface of the resin-impregnated fiber bundles. However, existing winding processes and equipment face significant technical bottlenecks in actual production; most mainstream winding devices use simple mechanical friction or counterweight methods to control the unwinding tension of the winding tape. This method is difficult to respond in real time to the differences in interlayer bonding forces within the winding tape master roll itself, resulting in frequent and uncontrollable fluctuations in winding tension. Unstable tension directly leads to uneven winding pitch and varying thread depth, affecting not only the consistency of product appearance but also weakening the final mechanical properties of the fiber reinforcement due to uneven stress distribution. Furthermore, existing winding devices often neglect effective axial constraint and protection of flexible, uncured fiber bundles in their structural design. During the spiral wrapping process, the rotating winding head applies continuous circumferential force to the fiber bundle. Without reliable longitudinal guidance and internal support, this can easily cause overall torsion or local bending of the fiber bundle. These geometric defects and internal stresses introduced in the early stages of molding will be retained or even amplified during the subsequent curing process, severely reducing the longitudinal straightness and axial tensile strength of the finished reinforcement.

[0003] Therefore, the inventors have proposed a fiber winding device to solve the above-mentioned technical problems. Summary of the Invention

[0004] The purpose of this invention is to provide a fiber winding device to solve the problem that the existing winding device has unstable tension control, resulting in uneven winding pitch, causing the fiber to bend in the longitudinal direction, which reduces the longitudinal tensile strength mechanical properties of the fiber.

[0005] To achieve the above objectives, the technical solution adopted by the present invention is as follows: A fiber reinforcement winding device includes a winding frame and a rotating assembly, wherein the rotating assembly is rotatably mounted on the winding frame; The rotating assembly includes at least one winding assembly, which is mounted on the rotating assembly and rotates synchronously with the rotating assembly. The winding assembly includes a winding tape fixing plate, a winding tape roll, and a clamping mechanism. The clamping mechanism is integrated on the winding tape fixing plate and has a tightening part for radially tightening the center hole of the winding tape roll and a pressure cap part for applying axial clamping force to the winding tape roll.

[0006] Furthermore, the rotating assembly includes a rotating shaft, a rotating bracket, and a driving component. The rotating shaft is rotatably mounted on the winding frame, the rotating bracket is fixedly connected to the rotating shaft, and the driving component is mounted on the winding frame to drive the rotating shaft to rotate. The rotating shaft is a hollow structure with openings at both ends, and a winding hole is provided in the middle of the rotating shaft.

[0007] Furthermore, it also includes an inner mold tube assembly, which includes a front inner mold tube and a rear inner mold tube disposed on the travel path of the fiber bundle assembly. The front inner mold tube and the rear inner mold tube are spaced apart within the rotating shaft and respectively fixed to the winding frame. Both the front inner mold tube and the rear inner mold tube are hollow structures used to provide axial support for the fiber bundle assembly. The area between the front inner mold tube and the rear inner mold tube constitutes a working area for winding the winding tape.

[0008] Furthermore, the tightening part includes a first screw fixedly installed on the shaft of the winding tape fixing disc, a first ring sleeve is sleeved on the first screw, and a plurality of first tightening claws are arranged around the first ring sleeve; A fixing ring is fixedly provided on the winding tape fixing plate. A plurality of first slide bars are slidably connected inside the fixing ring. One end of the first slide bar is connected to the corresponding first tightening claw. The other end of the first slide bar is hinged to a first connecting piece. The free end of the first connecting piece is hinged to the first ring. The first screw is threadedly connected to a first locking sleeve, which can drive the first ring sleeve to move.

[0009] Furthermore, the pressure cap includes a winding tape pressure cap sleeved outside the fixing ring. The winding tape pressure cap is located on the upper surface of the winding tape roll. A pressure cap connecting sleeve is provided on the winding tape pressure cap, and the pressure cap connecting sleeve is threadedly connected to the first screw.

[0010] Furthermore, the winding tape fixing disc is rotatably mounted on the rotating bracket, and a torque motor is fixedly installed on the other side of the rotating bracket. The output shaft of the torque motor passes through the rotating bracket and is coaxially and fixedly connected to the winding tape fixing disc.

[0011] Furthermore, the number of the winding assemblies is two, and the two winding assemblies are mounted on the rotating bracket.

[0012] Furthermore, the tightening part includes a second screw fixedly mounted on the shaft of the winding tape fixing disc, a second ring sleeve is sleeved on the second screw, the second ring sleeve can move up and down along the axial direction of the second screw, and a plurality of second tightening claws are arranged around the second ring sleeve; A second slide bar is provided between the second tightening claw and the second ring sleeve. One end of the second slide bar is connected to the corresponding second tightening claw, and the other end of the second slide bar is hinged to a second connecting piece. The free end of the second connecting piece is hinged to the second ring sleeve. A plurality of tension springs are provided between the second slide bar and the second connecting piece. The free end of the tension springs is connected to the second screw. The tension springs have a tendency to drive the second tightening claw to retract inward. A second locking sleeve is slidably connected to the second screw, and the second locking sleeve can drive the second ring sleeve to move.

[0013] Furthermore, the pressure cap includes a winding tape pressure cap, a pressure cap member is formed on the second locking sleeve, the bottom of the pressure cap member abuts against the winding tape pressure cap, and a connecting rope is provided between the second locking sleeve and the second tightening claw.

[0014] Furthermore, the winding tape fixing plate is fixedly installed on the rotating bracket, and a stepper motor is fixedly installed on the other side of the rotating bracket. The output shaft of the stepper motor passes through the rotating bracket and the winding tape fixing plate and is coaxially and fixedly connected to the second screw.

[0015] The beneficial effects of this invention are: This invention, by setting a torque motor coaxially connected to the winding tape fixing disc and pre-setting a constant output torque, can dynamically compensate for tension fluctuations caused by differences in the bonding force between layers of the winding tape in real time. This ensures that the winding tape maintains stable tension throughout the unwinding process, effectively solving the problems of uneven pitch and thread depth fluctuations caused by uneven tension in traditional winding devices. At the same time, the synergistic effect of the tightening part and the pressure cap part in the clamping mechanism not only achieves radial slip-free locking and axial deformation correction of the winding tape roll, but also prevents the fiber bundle assembly from twisting and deforming during the winding process by axially constraining the fiber bundle assembly through the front inner mold tube and the rear inner mold tube. This significantly improves the uniformity of the winding thread, the longitudinal straightness of the fiber ribs, and the stability of their axial mechanical properties.

[0016] One approach combines active control with a torque motor with manual / mechanical clamping, suitable for high-precision, continuous production scenarios involving constant tension winding. Another approach utilizes centrifugal force to drive a tightening cap linkage mechanism, achieving automatic clamping, flattening, and speed-based tension adjustment of the winding tape roll through purely mechanical means. This method is compact, responsive, and cost-effective, making it particularly suitable for production environments with high roll-changing efficiency requirements and relatively relaxed tension control precision. Both approaches support symmetrical arrangement of dual winding components, enabling continuous production without downtime while improving the dynamic balance of the rotating system. This demonstrates the comprehensive advantages of this invention in improving production efficiency, reducing equipment vibration, and extending service life, providing a flexible, reliable, and scalable equipment solution for fiber optic winding processes.

Detailed Implementation

[0020] The embodiments of the present invention will be described below with reference to the accompanying drawings and preferred embodiments. Those skilled in the art can easily understand other advantages and effects of the present invention from the content disclosed in this specification. The present invention can also be implemented or applied through other different specific embodiments, and various details in this specification can also be modified or changed based on different viewpoints and applications without departing from the spirit of the present invention. It should be understood that the preferred embodiments are only for illustrating the present invention and not for limiting the scope of protection of the present invention.

[0021] It should be noted that the illustrations provided in the following embodiments are only schematic representations of the basic concept of the present invention. Therefore, the drawings only show the components related to the present invention and are not drawn according to the actual number, shape and size of the components in the actual implementation. In the actual implementation, the form, quantity and proportion of each component can be arbitrarily changed, and the layout of the components may also be more complex.

[0022] This embodiment proposes a fiber winding device, such as... Figures 1 to 10 As shown, the device includes a winding frame A1 and a rotating assembly A2, which is rotatably mounted on the winding frame A1. The rotating assembly A2 includes at least one winding assembly A3, which is mounted on the rotating assembly A2 and rotates synchronously with the rotating assembly A2. The winding assembly A3 includes a winding tape fixing plate A31, a winding tape roll A32, and a clamping mechanism A33. The winding tape roll A32 has a central hole. The clamping mechanism A33 is integrated on the winding tape fixing plate A31. The clamping mechanism A33 has a tightening part A4 for radially tightening the central hole of the winding tape roll A32, and a pressure cap part A5 for applying axial clamping force to the winding tape roll A32.

[0023] In this embodiment, the winding tape roll A32 is fitted onto the winding tape fixing plate A31. The clamping mechanism A33 is operated to cause its tightening part A4 to expand radially, thereby tightening and locking the center hole of the winding tape roll A32. At the same time, the pressure cap part A5 applies axial pressure to the end face of the winding tape roll A32 to correct its warping deformation. During the winding process, the rotating component A2 drives the winding component A3 mounted on it to rotate around the axis of the fiber bundle assembly, causing the winding tape to unwind from the fixed winding tape roll A32 and wind around the surface of the fiber bundle assembly in a set spiral trajectory, thereby forming a threaded structure. During this process, the synergistic effect of the tightening part A4 and the pressure cap part A5 ensures the clamping stability of the winding tape roll A32 under high-speed rotation and effectively constrains the axial and radial deformation of the winding tape roll A32, providing a basis for the smooth and uniform release of the winding tape, thereby ensuring the consistency of the winding pitch and the stability of the winding quality.

[0024] In a preferred embodiment, the rotating assembly A2 includes a rotating shaft A21, a rotating bracket A22, and a driving component A23. The rotating shaft A21 is rotatably mounted on the winding frame A1, the rotating bracket A22 is fixedly connected to the rotating shaft A21, and the driving component A23 is mounted on the winding frame A1 to drive the rotating shaft A21 to rotate. The driving component A23 is a drive motor, which drives the rotating shaft A21 to rotate via a belt connection. The rotating shaft A21 is a hollow structure with openings at both ends, and a winding hole A24 is provided in the middle of the rotating shaft A21.

[0025] The drive motor starts and drives the rotating shaft A21 to rotate via a belt connection. The rotating bracket A22, which is fixedly connected to the rotating shaft A21, rotates synchronously. The winding tape roll A32 is locked to the winding tape fixing plate A31 on the rotating bracket A22 by the clamping mechanism A33. The winding tape is pulled out from the winding tape roll A32 and passes through the winding hole A24 opened in the middle of the rotating shaft A21. At the same time, the pre-impregnated resin fiber bundle assembly passes through the openings at both ends of the rotating shaft A21 and its hollow interior along the axial direction. Under the continuous rotation drive of the rotating shaft A21 and the rotating bracket A22, the winding tape is stably output through the winding hole A24 and is evenly and continuously wound on the surface of the passing fiber bundle assembly in a set spiral trajectory. The fiber bundle assembly wrapped with the winding tape continues to be conveyed forward into the subsequent heating and curing stage. After the resin is cured and shaped, the winding tape is peeled off by the unwinding device, and finally a fiber rib finished product with clear and regular threads on the surface is obtained.

[0026] In a preferred embodiment, the assembly further includes an inner mold tube assembly A6, which includes a front inner mold tube A61 and a rear inner mold tube A62 disposed on the travel path of the fiber bundle assembly. The front inner mold tube A61 and the rear inner mold tube A62 are spaced apart within the rotating shaft A21 and are respectively fixed to the winding frame body A1. Both the front inner mold tube A61 and the rear inner mold tube A62 are hollow structures used to provide axial support for the fiber bundle assembly. The area between the front inner mold tube A61 and the rear inner mold tube A62 constitutes a working area for winding the winding tape.

[0027] During the winding process, the fiber bundle assembly passes sequentially through the hollow channels of the front inner mold tube A61, the working area, and the rear inner mold tube A62. The front inner mold tube A61 and the rear inner mold tube A62 are fixedly connected to the winding frame body A1 through fixed supports. When the winding tape spirally winds around the surface of the fiber bundle assembly in the working area located between the front inner mold tube A61 and the rear inner mold tube A62, the front inner mold tube A61 and the rear inner mold tube A62 form an axial constraint on the fiber bundle assembly, preventing overall torsion or local bending due to the circumferential tension of the winding tape or the torsional force of the rotating support A22. At the same time, the front inner mold tube A61 and the rear inner mold tube A62 limit the actual winding area length of the winding tape within the limited distance between them, shortening the force transmission path between the winding tape and the fiber bundle assembly, reducing the risk of additional deformation caused by the uneven distribution of the tension of the winding tape along the fiber bundle axis, thereby ensuring the stability of the winding process, the regularity of the thread formation, and ultimately ensuring the straightness and axial mechanical properties of the fiber reinforcement product.

[0028] Example 1 like Figures 4 to 9 As shown, the tensioning part A4 includes a first screw A41a fixedly installed on the shaft of the winding tape fixing disc A31, a first ring sleeve A42a sleeved on the first screw A41a, and a plurality of first tensioning claws A43a arranged around the first ring sleeve A42a. like Figures 6 to 9 As shown, a fixing ring A44a is fixedly installed on the winding tape fixing disc A31. Several first slide bars A45a are slidably connected inside the fixing ring A44a. One end of the first slide bar A45a is connected to the corresponding first tightening claw A43a, and the other end of the first slide bar A45a is hinged to a first connecting piece A46a. The end of the first connecting piece A46a is hinged to a first ring sleeve A42a. A first locking sleeve A47a is threadedly connected to the first screw A41a. The first locking sleeve A47a can drive the first ring sleeve A42a to move.

[0029] After the winding tape roll A32 is fitted over the fixing ring A44a, the first locking sleeve A47a is screwed down to move axially downward along the thread of the first screw A41a. The downward movement of the first locking sleeve A47a pushes the first ring sleeve A42a in contact with it to move downward synchronously. The downward movement of the first ring sleeve A42a is transmitted through several first connecting pieces A46a hinged to it. Each first connecting piece A46a pulls the first slide bar A45a hinged to it to slide outward radially along the fixing ring A44a. The radial movement of A45a drives the first tightening claw A43a connected to it to expand outward in the radial direction of the winding tape fixing disc A31; as the first locking sleeve A47a continues to tighten downward, the knurled structure on the outer surface of the first tightening claw A43a gradually presses and embeds into the inner wall of the center hole of the winding tape roll A32, thereby achieving reliable locking and circumferential positioning of the entire winding tape roll A32 through increased radial friction, thus ensuring that the winding tape roll A32 does not experience relative slippage or eccentric vibration during high-speed rotation winding.

[0030] The capping part A5 includes a winding tape capping A51 sleeved outside the fixing ring A44a. The winding tape capping A51 is located on the upper surface of the winding tape roll A32. A capping connecting sleeve A52 is provided on the winding tape capping A51, and the capping connecting sleeve A52 is threadedly connected to the first screw A41a.

[0031] After the winding tape roll A32 is radially locked by the tightening part A4, the winding tape cap A51 is sleeved on the outside of the fixing ring A44a and covers the upper end face of the winding tape roll A32; the cap connecting sleeve A52, which is threaded onto the first screw A41a, is rotated so that it is screwed downward along the axial direction of the first screw A41a. The lower end face of the cap connecting sleeve A52 then presses against the upper surface of the winding tape cap A51, and pushes the winding tape cap A51 to move downward smoothly as a whole. The lower surface is uniformly pressed against the upper end face of the winding tape roll A32, applying an adjustable and continuous axial pressure. This axial pressure effectively corrects the deformation of the winding tape roll A32, such as end face warping and interlayer loosening, which may occur due to its own winding or storage. This ensures that the winding tape roll A32 maintains a flat end face and stable interlayer during high-speed rotation and unwinding, thereby preventing tension fluctuations in the winding tape release caused by the deformation of the winding tape roll A32 itself, and further ensuring the uniformity and consistency of the winding pitch.

[0032] In a preferred embodiment, the winding tape fixing disc A31 is rotatably mounted on the rotating bracket A22, such as Figure 4As shown, a torque motor A7 is fixedly installed on the other side of the rotating bracket A22. The output shaft of the torque motor A7 passes through the rotating bracket A22 and is coaxially fixedly connected to the winding tape fixing plate A31. The output shaft of torque motor A7 is coaxially and fixedly connected to the winding tape fixing disc A31. The output torque of torque motor A7 is preset to a constant value corresponding to the required winding tension by the controller. During the winding process, when the interlayer bonding of the winding tape roll A32 is tight and the unwinding resistance is normal, the winding tape tension can be maintained within the set range, and torque motor A7 does not move actively. When encountering a section in the winding tape roll A32 where the interlayer bonding is loose, the winding tape tension will drop instantaneously. At this time, the resistance torque of the winding tape to the fixing disc is lower than the preset output torque of torque motor A7. Then, according to its torque control characteristics, torque motor A7 automatically rotates in the opposite direction of winding tape tightening, actively driving winding tape fixing disc A31 to tighten the loose winding tape. Through this dynamic adjustment, torque motor A7 continuously compensates for tension fluctuations caused by material inhomogeneity, so that the winding tape maintains a basically constant tensile tension during the unwinding process, thereby ensuring that the pitch of the winding tape wound onto the surface of the fiber bundle assembly is uniform and consistent, effectively avoiding uneven thread density caused by sudden tension drops.

[0033] It should be noted that, in the preferred embodiment of this example, the torque motor A7 used is a widely used and technologically mature type of motor in the field. Its working principle and output characteristics are clearly described in existing technologies (such as patent documents, motor product manuals, and automation control textbooks). The torque motor A7 can be set and maintained with a constant output torque by an external controller. When the load torque is lower than its set value, the motor will actively rotate until the load torque is balanced with the set torque, thereby achieving closed-loop dynamic control of the tension of the winding tape. This torque motor A7, through its inherent torque-speed characteristic curve and the cooperation of the feedback control circuit, can automatically identify tension fluctuations caused by changes in the interlayer bonding force of the winding tape and adjust the rotation direction and speed in real time to compensate for tension deviations. Therefore, the use of the torque motor A7 as the constant tension control actuator in this embodiment is a reasonable application of the inherent function of a known component. Its implementation method and technical effects are clear, explicit, and achievable for those skilled in the art, and meet the requirements of the patent law regarding the clarity of claims.

[0034] In this embodiment, the tightening part A4 drives the first tightening claw A43a to expand radially through the first locking sleeve A47a, so that the knurled surface on the outer side of the first tightening claw A43a is tightly fitted with the inner ring of the winding tape roll A32, ensuring that the winding tape roll A32 and the winding tape fixing disc A31 are connected without circumferential slippage, and preventing sudden changes in unwinding resistance caused by clamping looseness; at the same time, the pressure cap part A5 presses down on the winding tape pressure cap A51 through the pressure cap connecting sleeve A52, applying axial clamping force to the end face of the winding tape roll A32, effectively correcting the warping of the winding tape roll A32 itself. The slack between the layers eliminates the release jamming and tension jumps caused by the deformation of the winding tape A32; together, they provide a stable mechanical basis for the constant tension control of the torque motor A7, allowing the winding tape to be released evenly and smoothly, thereby ensuring the consistency of the winding pitch and the stability of the thread depth, and reducing the local circumferential impact on the fiber bundles caused by uneven release of the winding tape. Combined with the axial constraints of the front inner mold tube A61 and the rear inner mold tube A62, they jointly suppress the torsional tendency of the fiber bundle assembly, and improve the longitudinal straightness and axial mechanical properties of the subsequently formed fiber ribs.

[0035] In a preferred embodiment, two winding components A3 are installed on a rotating support A22. The two winding components A3 are symmetrically installed on the rotating support A22, forming a continuous production mode or a collaborative balancing operation mechanism with one in use and one on standby. When the winding tape roll A32 on one of the winding components A3 is about to run out, the spare winding component A3 can be pre-loaded with a new winding tape roll A32 and pre-tightened. When switching is required, simply transfer the winding tape from the nearly exhausted winding tape roll A32 to the new winding tape roll A32 and fix the end to achieve uninterrupted continuous winding, significantly reducing production downtime. Simultaneously, the symmetrical arrangement of the two winding components A3 on the rotating support A22 ensures that their own mass and the mass of the loaded winding tape roll A32 are balanced during rotation. This effectively reduces vibration and dynamic load caused by mass eccentricity in the rotating system, making the rotating support A22 run more smoothly under the drive of the torque motor A7, further improving the stability of the winding process and the consistency of thread forming, and extending the service life of the device.

[0036] Example 2 In this embodiment, as Figure 10As shown, the tightening part A4 includes a second screw A41b fixedly mounted on the shaft of the winding tape fixing disc A31. A second ring sleeve A42b is sleeved on the second screw A41b, and the second ring sleeve A42b can move up and down along the axial direction of the second screw A41b. A plurality of second tightening claws A43b are arranged around the second ring sleeve A42b. A second slide bar A45b is arranged between the second tightening claws A43b and the second ring sleeve A42b. One end of the second slide bar A45b is connected to the corresponding second tightening claw A43b. The other end of the strip A45b is hinged to a second connecting piece A46b, and the free end of the second connecting piece A46b is hinged to a second ring A42b. A plurality of tension springs A44b are provided between the second sliding strip A45b and the second connecting piece A46b. The free end of the tension springs A44b is connected to a second screw A41b, and the tension springs A44b have a tendency to drive the second tightening claw A43b to retract inward. A second locking sleeve A47b is slidably connected to the second screw A41b, and the second locking sleeve A47b can drive the second ring A42b to move. The pressure cap A5 includes a winding tape pressure cap A51. A pressure cap A521 is formed on the second locking sleeve A47b, and the bottom of the pressure cap A521 abuts against the winding tape pressure cap A51. A connecting rope A53 is provided between the second locking sleeve A47b and the second tightening claw A43b. The winding tape fixing plate A31 is fixedly installed on the rotating bracket A22. A stepper motor A8 is fixedly installed on the other side of the rotating bracket A22. The output shaft of the stepper motor A8 passes through the rotating bracket A22 and the winding tape fixing plate A31 and is coaxially fixedly connected to the second screw A41b.

[0037] When stepper motor A8 starts, it drives the second screw A41b, which is coaxially fixed to the output shaft of stepper motor A8, to rotate. Under the centrifugal force generated by the rotation, the second connecting piece A46b pushes the second slide bar A45b to slide radially outward along the winding tape fixing disc A31. This causes the connected second tightening claw A43b to expand outward against the radial contraction force of the tension spring A44b, so that the knurled structure on the outer surface of the second tightening claw A43b presses against the inner wall of the center hole of the winding tape roll A32, achieving radial locking of the winding tape roll A32. At the same time, the second tightening claw A43b... When expanding outward, the connecting rope A53 has a component force that pulls the second locking sleeve A47b downward along the axial direction of the second screw A41b, causing it to move downward. The downward movement of the second locking sleeve A47b causes the pressure cover A521 to move downward synchronously. The pressure cover A521 presses against the winding tape pressure cover A51, thereby applying axial pressure force to the upper end face of the winding tape roll A32. At the same time, the knurled structure on the outer surface of the second tightening claw A43b expands radially and presses into the inner wall of the center hole of the winding tape roll A32, achieving radial locking. This realizes the linkage control of radial tightening and axial pressing actions. Only a single power input (such as the centrifugal force driven by the stepper motor A8) is needed to simultaneously lock the center hole of the winding tape roll A32 and level the end face, significantly simplifying the clamping operation steps and the number of required drive components, improving roll changing efficiency and reducing equipment complexity. The linkage design ensures that the radial fixing and axial pressing of the winding tape roll A32 are completely synchronized in timing and coordinated in force, avoiding problems such as roll skewing, local stress concentration or uneven clamping that may be caused by step-by-step operation. This ensures the dynamic stability and concentricity of the roll during high-speed rotation and unwinding, providing a uniform and stable tension foundation for subsequent winding processes. At the same time, the integrated linkage structure can automatically and quickly release the winding pad roll through the reset action of the tension spring A44b when disassembling, further improving the convenience of operation and production continuity. It is particularly suitable for production scenarios with relatively relaxed tension accuracy requirements and a pursuit of efficient assembly and disassembly and cost optimization.
