Description

Technical Field

[0001] The present application relates to the technical field of optical fiber production, and in particular to a double-wheel twisting calibration device for optical fiber drawing. Background Art

[0002] In the field of optical fiber manufacturing, the technology behind the dual-wheel twisting calibration device and its supporting equipment directly impacts the quality and production efficiency of optical fiber products. As a key step in the optical fiber production process, dual-wheel twisting devices and other optical fiber components play a vital role in precisely controlling the fiber's state during the drawing process, effectively reducing fiber breakage and coating damage caused by uneven stress during high-speed drawing, thereby significantly improving the yield of optical fiber and the stability of equipment operation.

[0003] In recent years, with the rapid development of optical fiber communication technology, the requirements for optical fiber quality have become increasingly stringent. How to further optimize optical fiber manufacturing and thus improve stable performance has become a common focus of attention within and outside the industry. Although current optical fiber drawing technology has made significant achievements, such as increased automation, faster drawing speeds, and overall improvements in optical fiber quality, it still faces many challenges in the commissioning and maintenance of related processing components. For example, the installation and commissioning process of the existing double-wheel twisting device is highly dependent on the operator's experience and judgment. There is a lack of accurate data support for the adjustment of the verticality, horizontal position, and flexibility of the wheel system, making it difficult to ensure the long-term stability of polarization mode dispersion under high-speed drawing conditions. This not only increases the difficulty and cost of commissioning, but also limits the further improvement of optical fiber production efficiency.

[0004] Furthermore, existing systems lack an effective real-time monitoring system to verify the working status of processing components during the actual drawing process after installation. This can lead to gradual loss of optimal performance due to minor deviations or wear during high-speed, continuous production, resulting in increased fiber breakage rates and coating scrap rates, thus impacting overall production efficiency. Therefore, to overcome these technical bottlenecks, it is necessary to minimize the use of resources to pre-measure the processing components of the dual-wheel twist calibration device used in optical fiber drawing. Summary of the Invention

[0005] The purpose of the present application is to provide a dual-wheel twisting and checking device for optical fiber drawing, which can independently realize the detection of specific processing components and can test related components without the need for overall operation, thereby saving resources and improving efficiency. The dual-wheel twisting and checking device for optical fiber drawing includes at least one optical fiber dual-wheel twisting component, a positioning wheel, a traction wheel, a take-up machine, and a test and pay-off component;

[0006] The positioning wheel guides and positions the optical fiber to be processed in the double-wheel twisting and checking device during optical fiber drawing;

[0007] The test pay-off component independently provides a test optical fiber, and the test optical fiber passes through the optical fiber double-wheel twisting component to be tested, thereby testing the optical fiber double-wheel twisting component;

[0008] The traction wheel and the take-up machine are used to convey and collect the processed optical fiber or test optical fiber;

[0009] Wherein, the test pay-off component includes an auxiliary wheel, and the auxiliary wheel is used to transmit the test optical fiber to the optical fiber double-wheel twisting component.

[0010] In one embodiment, the optical fiber double-wheel twisting component includes a twisting platform, and the twisting platform includes more than two twisting wheels.

[0011] In one embodiment, at least one positioning wheel is provided on the inlet and outlet sides of the twisting platform.

[0012] In one embodiment, the optical fiber to be processed and the test optical fiber pass through the twisting platform in a vertical direction.

[0013] In one embodiment, the test payout component includes a plurality of small-disk optical fiber placement positions.

[0014] In one embodiment, the test optical fiber includes an identification mark.

[0015] In one embodiment, the optical fiber testing component is further included, and the test pay-out component is also used to provide a test optical fiber to the optical fiber testing component.

[0016] In one embodiment, the test pay-off component further includes a fiber recovery wheel, and the fiber recovery wheel is used to recover the optical fiber that has passed through the optical fiber double-wheel twisting component into the test pay-off component.

[0017] In one embodiment, the auxiliary wheel further includes a temperature control component, and the temperature control component indirectly adjusts the temperature of the test optical fiber by controlling the temperature of the auxiliary wheel.

[0018] In one embodiment, the auxiliary wheel further includes a static electricity removal component, which is electrically connected to the optical fiber double-wheel twisting component, the positioning wheel, and the traction wheel to conduct static electricity.

[0019] Compared with the existing technology, the present application has the following beneficial effects: This application provides a dual-wheel twisting calibration device for optical fiber drawing. By introducing an additional test payout component and its supporting control mechanism, it achieves comprehensive testing and evaluation of the optical fiber dual-wheel twisting component (especially the PMD system) under simulated actual drawing conditions, thereby improving the stability and overall pass rate of the optical fiber production process. The newly added test payout component can simulate the movement state of the optical fiber during normal drawing, allowing the PMD system and other optical fiber dual-wheel twisting components to be tested in an environment close to actual production conditions, ensuring the accuracy and reliability of the test results and providing guarantees for quality control during the production process.

[0020] After the installation of the PMD platform and other processing components is completed, this application can immediately determine whether the relevant systems are in normal operation by simulating the working status, and can avoid the use of actual drawing processes for testing and inspection. Through simulation testing, operators can discover and solve potential problems in actual production in advance, thereby effectively reducing optical fiber quality defects caused by equipment failures. This preventive maintenance measure significantly improves the overall qualification rate of optical fiber products and reduces scrap rate and production costs. This application adds a small-disk optical fiber pay-off traction control system to the right side of the original twisting platform, and uses the main traction speed signal for synchronous control. At the same time, an auxiliary guide wheel is added above the upper positioning wheel to further optimize the optical fiber transmission path. By installing a small disk of optical fiber on the bracket and starting the main traction system to the normal drawing speed, the stability of the twisting state during the take-up process can be intuitively observed to confirm whether the twisting system meets the actual drawing conditions. This process does not require actual production, which greatly shortens the debugging cycle. BRIEF DESCRIPTION OF THE DRAWINGS

It will be understood that the specific embodiments described herein are only used to explain the present application, rather than to limit the present application.

Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of this application.

For example, a process, method, system, product, or apparatus comprising a series of steps or elements is not limited to the listed steps or elements but may optionally include steps or elements not listed, or may optionally include other steps or elements inherent to the process, method, product, or apparatus.

[0026] References herein to "embodiments" mean that a particular feature, structure, or characteristic described in connection with the embodiments may be included in at least one embodiment of the present application. The appearance of this phrase in various places in the specification does not necessarily refer to the same embodiment, nor does it constitute an independent or alternative embodiment that is mutually exclusive of other embodiments. It is understood, both explicitly and implicitly, by those skilled in the art that the embodiments described herein may be combined with other embodiments.

[0027] In the existing technology of double-wheel twisting calibration device for optical fiber drawing, the debugging and maintenance of optical fiber double-wheel twisting components (such as double-wheel twisting device FSU) are highly dependent on the operator's experience, lacking accurate data support and real-time monitoring means. In addition, the installation and debugging process of optical fiber double-wheel twisting components is complicated and time-consuming, and often needs to be verified under the operation state of the whole machine. In response to the above technical problems, this application proposes a technical solution for double-wheel twisting calibration device for optical fiber drawing, please refer to Figure 1In a preferred embodiment of the present application, a double-wheel twisting calibration device for optical fiber drawing is suitable for independently realizing the detection of specific processing components. It can test related components without the need for overall operation, thereby saving resources and improving efficiency. It includes at least one optical fiber double-wheel twisting component 100, a positioning wheel 200, a traction wheel 300, a take-up machine 400 and a test pay-off component 500. The positioning wheel 200 is used in the double-wheel twisting calibration device for optical fiber drawing to ensure that the transmission path of the optical fiber in the drawing furnace is accurate and reduce problems caused by position offset. The test pay-off component 500 independently provides a test optical fiber, and the test optical fiber passes through the optical fiber double-wheel twisting component 100 to be tested, thereby testing the optical fiber double-wheel twisting component 100. The traction wheel 300 and the take-up machine 400 are used to transmit and collect the processed optical fiber or test optical fiber, independently provide the test optical fiber, and pass through the optical fiber double-wheel twisting component 100 to be tested through a specific path, allowing the optical fiber double-wheel twisting component 100 to be quickly and accurately performed performance testing and fault diagnosis without utilizing the normal production process, thereby improving the convenience and efficiency of equipment maintenance.

[0028] The test pay-off component 500 includes an auxiliary wheel 510, which is used to transfer the test optical fiber to the optical fiber double-wheel twisting component 100. As a key component of the test pay-off component 500, the auxiliary wheel 510 independently and smoothly transfers the test optical fiber to the optical fiber double-wheel twisting component 100. The auxiliary wheel 510 can adjust its position to different optical processing components 100 to achieve independent testing of each optical fiber double-wheel twisting component 100. By using the test optical fiber in advance to simulate the normal production process, the continuity and stability of each processing component can be tested without the need for actual production. At the same time, standard test optical fiber can also be used to evaluate the accuracy and stability of the measurement components.

[0029] The introduction of the test payout component 500 makes the testing process of the optical fiber double-wheel twisting component 100 more independent and flexible, allowing it to be performed without the need for actual optical fiber production, thereby shortening the testing cycle and improving testing efficiency. Furthermore, because the test optical fiber directly passes through the component to be tested, the test results are close to the actual production status, ensuring test accuracy. By regularly testing the optical fiber double-wheel twisting component 100, potential faults can be promptly discovered and eliminated, avoiding material waste caused by component failure during the production process. Since the test payout component 500 allows testing without the need for actual production, production losses caused by actual material consumption are reduced. Furthermore, accurate testing and timely maintenance also extend the service life of the optical fiber double-wheel twisting component 100, further reducing maintenance costs. Furthermore, the design of the test payout component 500 enables the double-wheel twisting calibration device in optical fiber drawing to flexibly handle the processing requirements of optical fibers of different specifications and materials. By replacing or adjusting the combination of the test optical fiber and the optical fiber double-wheel twisting component 100, changes in materials or structures can be quickly adapted.

[0030] Please see further Figure 2 The optical fiber dual-wheel twisting component 100 includes a twisting platform 110, which includes two or more twisting wheels 111. The optical fiber dual-wheel twisting component 100 can be selected as a twisting platform 110. The twisting platform 110 uses two or more high-precision, coordinated twisting wheels 111 to more accurately control the twisting angle and force of the optical fiber. Through independent drive and precise control, each twisting wheel 111 can be fine-tuned according to the actual situation of the optical fiber, ensuring that the optical fiber maintains a stable operating state during the twisting process.

[0031] In order to further improve the stability and accuracy of the optical fiber during the twisting process, at least one positioning wheel 200 is respectively provided on the inlet and outlet sides of the twisting platform 110, that is, at least one positioning wheel 200 is respectively provided on the inlet and outlet sides of the twisting platform 110. The positioning wheel 200 can be made of a high-strength, low-friction coefficient material, and the surface is specially treated to ensure that the contact surface with the optical fiber is smooth and damage-free, thereby realizing the dynamic stability of the optical fiber during high-speed movement.

[0032] The optical fiber to be processed and the test optical fiber are guided to a twisting platform 110 that integrates a positioning mechanism and an automatic correction system. The optical fiber to be processed and the test optical fiber pass through the twisting platform 110 in a vertical direction. The platform adopts a vertical direction to ensure that the optical fiber maintains verticality during the passage process, which can effectively avoid problems such as optical fiber distortion, scratches or performance degradation caused by angle deviation.

[0033] To achieve efficient and organized test fiber management and supply, the test payout component adopts a modular design that can integrate multiple independent and flexible small-disc fiber placement locations. That is, the test payout component includes multiple small-disc fiber placement locations. Through the configuration of multiple small-disc fiber placement locations, optical fibers are orderly classified and stored. The modular design makes the test payout component highly flexible and can be flexibly configured according to actual fiber processing needs. Whether adding new fiber types or expanding fiber storage capacity, this can be achieved by simply increasing or decreasing the number of small-disc fiber placement locations, without the need for large-scale modifications to the entire system.

[0034] To improve the accuracy and efficiency of fiber optic testing, the test fiber includes an identification mark. This mark can contain key information about the fiber, such as serial number, type, length, batch number, etc., for rapid identification and tracking during testing. By placing identification marks on the test fiber, testers can quickly confirm the corresponding model and parameters of the fiber. Each identification mark contains detailed information about the fiber, which makes the fiber highly traceable throughout the entire testing, processing, and subsequent applications. If a problem occurs, the identification mark can be used to quickly locate the specific fiber and its related information, facilitating problem identification and resolution.

[0035] In the double-wheel twisting calibration device for optical fiber drawing, in order to evaluate the optical fiber drawing effect, an optical fiber test component is also included, which actually detects the drawn optical fiber in real time. The test pay-off component 500 is also used to provide test optical fiber to the optical fiber test component. The test pay-off component 500 can also convey optical fiber to the optical fiber test component to verify the accuracy of the optical fiber test component through standard test optical fiber. The test pay-off component 500 can automatically adjust the tension, speed and path of the optical fiber according to the test requirements to ensure that the optical fiber enters the optical fiber test component in the optimal state. The test pay-off component 500 can intelligently provide test optical fibers of different specifications and types, making the test more widely applicable.

[0036] In order to take into account the recovery of the optical fiber after the test is completed, the test pay-off component 500 also includes a fiber recovery wheel, which is used to recycle the optical fiber that has passed through the optical fiber double-wheel twisting component 100 into the test pay-off component 500. The optical fiber recovery wheel can be equipped with an intelligent control system that can monitor the recovery status of the optical fiber in real time, including parameters such as the recovery speed, tension, and the remaining amount of optical fiber, and automatically adjust the working state of the recovery wheel accordingly to achieve the optimal recovery efficiency. Most importantly, the present application adopts a fiber recovery wheel that can independently provide and recover the test optical fiber through the test pay-off component 500, thereby completing the test of the optical fiber double-wheel twisting component 100 or the optical fiber test component.

[0037] Specifically, the auxiliary wheel 510 also includes a temperature control element, which indirectly adjusts the temperature of the test fiber by controlling the temperature of the auxiliary wheel 510. The temperature control element, through a built-in heating element or cooling system, can precisely adjust the surface temperature of the auxiliary wheel 510, thereby indirectly adjusting the temperature of the test fiber wrapped around or in contact with the auxiliary wheel 510. This enhances the functionality of the auxiliary wheel 510 and provides the test system with a wider range of environmental adaptability and testing flexibility. By controlling the temperature of the test fiber, fluctuations in fiber performance caused by temperature changes, such as refractive index changes and thermal stress, can be eliminated or reduced, thereby improving the accuracy and reliability of the test. In some test scenarios where rapid adjustment of the fiber temperature is required, the temperature control element can quickly respond and adjust the temperature of the auxiliary wheel 510, thereby achieving rapid adjustment of the test fiber temperature, shortening test preparation time and improving test efficiency.

[0038] To address the static electricity that may accumulate during the handling of the test optical fiber, the auxiliary wheel 510 of this application further includes a static electricity removal component. Static electricity can cause minor but significant interference to the optical test system, such as causing signal noise and affecting measurement accuracy. The static electricity removal component further optimizes the test environment and significantly improves test accuracy. The static electricity removal component is electrically connected to the optical fiber dual-wheel twisting component 100, the positioning wheel 200, and the traction wheel 300 to remove static electricity. Integrating the static electricity removal component into the design of the auxiliary wheel 510 can improve the performance of the optical test system, protect the quality of the optical fiber, increase test accuracy, and enhance system security.

[0039] As can be seen from the foregoing, this application provides a highly efficient and energy-efficient dual-wheel twist calibration device for optical fiber drawing. Its integrated independent detection mechanism allows for precise testing of critical dual-wheel twist components without activating the overall production process. The core components of this system include: at least one dual-wheel twist component (e.g., a twisting platform equipped with multiple twisting wheels), a positioning wheel, a traction wheel, a take-up mechanism, and an innovative test and pay-out component.

[0040] The positioning wheel is responsible for accurately guiding the optical fiber to be processed to the designated position; the test pay-off component independently supplies the test optical fiber, which passes through the double-wheel twisting component of the optical fiber to be tested to achieve local performance verification without the need for overall equipment operation, significantly improving test efficiency and resource utilization. During the test process, the auxiliary wheel, as a key component, is not only responsible for smoothly transporting the test optical fiber to the processing component, but can also be equipped with a temperature control component as needed to indirectly adjust the temperature of the optical fiber to ensure the consistency of the test conditions. In addition, the static electricity removal component integrated in the auxiliary wheel is electrically connected to the optical fiber double-wheel twisting component, the positioning wheel and the traction wheel, effectively eliminating static electricity interference and ensuring test accuracy and equipment safety. In addition, it can also be expanded to include an optical fiber test component, and the test pay-off component can also provide test optical fiber to this component, thereby supporting more comprehensive optical fiber quality evaluation and performance verification. In summary, the double-wheel twisting calibration device in optical fiber drawing of this patent application realizes efficient and accurate testing of the optical fiber double-wheel twisting component through the design of independent detection modules and the integration of functional components.

[0041] The above is only a specific implementation of the present application. Any other improvements made based on the concept of the present application are considered to be within the scope of protection of the present application.
