Description

Technical Field

[0001] The invention relates to the technical field of production and manufacturing of polarization-maintaining optical fiber rings, and in particular to a rotation method and a device for improving the uniformity of glue in polarization-maintaining optical fiber rings. Background Art

[0002] Fiber optic gyroscope is an angular motion detection device that uses the Sagnac effect to detect the angular velocity of the loop plane and then accurately calculate the motion posture of the object. In the field of modern science and technology, especially in high-precision demand scenarios such as aerospace, navigation and positioning, fiber optic gyroscopes play a pivotal role. Its core optical path components, especially the polarization-maintaining fiber ring, are the core sensitive components for detecting angular velocity. Its manufacturing quality directly determines the performance level of the fiber optic gyroscope.

[0003] The manufacturing process of polarization-maintaining fiber rings is quite complicated. It is necessary to accurately wind a complete polarization-maintaining fiber on a metal skeleton and shape it into a ring by applying glue and curing. Depending on the timing of applying glue, the winding process of polarization-maintaining fiber rings is mainly divided into two types: dipped glue winding and glue-banded glue winding. Although dipped glue winding can achieve high uniformity of glue and effective control of bubbles in the ring, it has inherent defects such as long production cycle, large glue consumption, and high production cost. In particular, with the increasingly obvious trend of miniaturization of fiber optic gyroscopes, the outer diameter of polarization-maintaining optical fibers has gradually decreased, and the difficulty of leaving gaps and glue penetration during dipped glue winding has increased significantly, further limiting its application.

[0004] In contrast, the adhesive winding process shows a broader development prospect because it adapts to the miniaturization trend of fiber optic gyroscopes and has a lower production cost. However, the biggest challenge of the adhesive winding process is the control of adhesive uniformity. Since the process involves many variables, such as human operation, equipment operation stability, optical fiber and glue matching, process techniques, and ambient temperature changes, the combined effect of these factors often causes the glue to be unevenly distributed in the fiber ring, resulting in uneven stress inside the polarization-maintaining fiber ring, thereby affecting the performance consistency and reliability of the polarization-maintaining fiber ring, and reducing the product's qualification rate and overall performance. Summary of the invention

[0005] In view of this, the present invention aims to address the deficiencies in the prior art, and its main purpose is to provide a rotation method and device for improving the uniformity of glue in a polarization-maintaining optical fiber ring, which solves the technical problem that uneven glue distribution in the adhesive winding process leads to uneven internal stress of the polarization-maintaining optical fiber ring, thereby affecting the performance consistency and reliability of the polarization-maintaining optical fiber ring.

[0006] To achieve the above purpose, the present invention adopts the following technical solutions:

[0026] Among them, ω sp represents the current rotation speed setting value, ω pv represents the current actual value of the rotation speed. If the absolute value of the difference between the current rotation speed setting value and the current actual value of the rotation speed is greater than or equal to m, the process proceeds to step S5025; otherwise, the process proceeds to step S5026;

[0029] S5025, triggering an alarm, and at the same time the rotating device stops the rotating processing step;

[0030] S5026, the rotating device continues to rotate until the current rotation time setting value is reached, then stops rotating and notifies the subsequent process to proceed to the next step of operation.

[0031] As a preferred solution, the ambient temperature fluctuation information includes a maximum ambient temperature of the functional area and a minimum ambient temperature of the functional area, and the ambient temperature fluctuation amplitude value is equal to the difference between the maximum ambient temperature of the functional area and the minimum ambient temperature of the functional area, including the following formula:

[0034] As a preferred solution, based on step S5026, the following steps are included:

[0035] 5 to 10 minutes before the rotation of the rotating device ends, the rotating device emits a prompt sound indicating that the rotation is about to end, and notifies the next process in advance to prepare for the process docking;

[0036] When the rotation is finished, the rotating device emits a rotation completion prompt sound and notifies the next process to proceed with the process docking step;

[0037] If it is detected that the processed optical fiber ring to be rotated has not been taken out 10 minutes after the rotation is completed, the rotating device emits a product retention prompt sound and notifies the next step of the process.

[0061] In order to make the purpose, technical solution and advantages of the present invention more clearly understood, the present invention is further described in detail below in conjunction with the accompanying drawings and implementation examples. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not intended to limit the present invention.

[0062] It should be noted that when an element is referred to as being "fixed to" another element, it may be directly on the other element or there may be a central element. When an element is considered to be "connected to" another element, it may be directly connected to the other element or there may be a central element at the same time. The terms "vertical", "horizontal", "left", "right" and similar expressions used herein are for illustrative purposes only.

[0063] Example 1

[0064] See also Figures 1 to 3 The embodiment of the present invention provides a rotation method for improving the uniformity of polarization-maintaining optical fiber ring glue, comprising the following steps:

[0065] S01, the step of building and initializing the process parameter database to provide accurate and comprehensive data support for subsequent steps.

[0066] This step ensures that all parameters required in the processing have a basis to rely on, thus improving the accuracy and reliability of the processing.

[0067] S02, a step of placing the optical fiber ring to be rotated on a rotating device, ensuring that the optical fiber ring to be rotated is stably and firmly installed.

[0068] It should be noted that stable installation is the basis for the smooth progress of subsequent processing, avoiding processing errors caused by loosening or displacement of the optical fiber ring to be rotated.

[0069] S03, identifying the optical fiber ring to be rotated, collecting the current ambient temperature, and matching it with the process parameter database, and gradually obtaining the model parameters, glue model, glue viscosity and rotation parameters of the current optical fiber ring to be rotated.

[0070] This step ensures that the machining process matches the characteristics of the fiber optic ring and glue being tested, thereby ensuring the spin processing effect and improving product quality and performance.

[0071] S04, a step for presetting a time interval for monitoring and recording, so that the subsequent steps can record key information on time and accurately.

[0072] Here, by monitoring and recording at preset time intervals, the dynamic changes of the processing process can be grasped in real time, providing strong data support for subsequent analysis and optimization.

[0073] S05, start the rotating device to process the rotating optical fiber ring, and record the rotation state information and ambient temperature fluctuation information at preset time intervals, calculate the ambient temperature fluctuation amplitude value, and perform abnormal detection and judgment at the same time. If it is abnormal, an alarm will be issued and the process will be terminated. Otherwise, the process will continue to be completed and the next step will be notified.

[0074] It should be noted that this step not only monitors the stability of the processing and the influence of ambient temperature in real time, but also promptly issues an alarm and stops processing when an abnormality occurs, thus avoiding the production of defective products and damage to equipment, and ensuring the continuity and efficiency of the entire processing process.

[0075] Here, it is also necessary to clarify the principle of this method: the polarization-maintaining optical fiber ring and its frame that have been wound with glue are fixed on a rotating axis and rotated at a certain angular velocity for a certain period of time, so that the empty glue area of ​​some optical fibers in the ring body can be replenished with glue under a certain degree of centrifugal action.

[0076] In this embodiment, the process parameter database includes a fiber optic ring model table, a glue model comparison table matching the fiber optic ring model table, a glue viscosity-temperature correspondence table associated with the glue model comparison table, and a rotation parameter table based on the glue viscosity, wherein the rotation parameters include the current rotation speed setting value and the current rotation time setting value.

[0077] Among them, the fiber ring model table clearly records the specifications and parameters of each fiber ring, providing accurate fiber ring information for subsequent processing. The glue model comparison table that matches the fiber ring model table records the glue model corresponding to each fiber ring information. The glue viscosity-temperature correspondence table associated with the glue model comparison table is used to accurately estimate the viscosity of the glue at different ambient temperatures. The rotation parameter table based on the glue viscosity lists in detail the rotation speed setting values ​​and rotation time setting values ​​required for glues of different viscosities to ensure that the processing process can be carried out according to the optimal rotation parameters, thereby obtaining a polarization-maintaining fiber ring with good glue uniformity. The construction and mutual correlation of these database tables provide comprehensive and accurate data support for the entire rotation processing process, ensuring the improvement of processing quality and efficiency.

[0078] In addition, it should be noted that the current rotation speed setting value is mainly related to the glue viscosity and the ambient temperature. Specifically, the greater the glue viscosity and the lower the ambient temperature, the faster the rotation speed. The current rotation time setting value is mainly related to the size of the optical fiber ring to be rotated. Specifically, the larger the outer diameter and the greater the height of the optical fiber ring to be rotated, the longer the rotation time.

[0079] Therefore, for different types of polarization-maintaining fiber rings, the glue used may also be different due to their different outer diameters and heights. Different glues have different viscosity-temperature characteristics. Therefore, after identifying the type of polarization-maintaining fiber ring and the type of glue used, it is also necessary to know the current ambient temperature in order to estimate the viscosity of the glue at this time.

[0080] Further, based on step S03, the following steps are included:

[0081] S301, a step of matching the optical fiber ring to be rotated with an optical fiber ring model table through automatic identification technology to obtain model parameters of the current optical fiber ring to be rotated.

[0082] It should be noted that the automatic identification technology can quickly and accurately identify the model of the fiber optic ring, provide accurate fiber optic ring information for subsequent steps, and avoid the errors and delays that may be caused by manual identification.

[0083] S302, a step of determining an adapted glue model according to the identified model parameters of the current optical fiber ring to be rotated and referring to a glue model comparison table.

[0084] Through precise matching, the compatibility and bonding effect between the glue and the fiber optic ring can be ensured, thus improving the quality and reliability of the product.

[0085] S303, collecting the current ambient temperature, and obtaining the glue viscosity according to the glue model and the glue viscosity-temperature correspondence table.

[0086] Ambient temperature has an important influence on glue viscosity. By collecting the current ambient temperature in real time and combining it with the glue viscosity-temperature correspondence table, the viscosity of the glue at the current ambient temperature can be accurately estimated, providing key data support for the subsequent setting of rotation parameters.

[0087] S304 is a step of retrieving and determining a current rotation speed setting value and a current rotation time setting value adapted by the rotating device from a rotation parameter table based on the viscosity of the glue.

[0088] It should be noted that the rotation speed and rotation time are key factors affecting the uniformity of the glue. By accurately setting the rotation parameters according to the viscosity of the glue, it can be ensured that the glue is evenly distributed in the fiber ring, thereby improving the quality and consistency of the product.

[0089] Based on step S05, the following steps are included:

[0090] S501, start the rotating device, and perform rotation processing on the rotating optical fiber ring according to the determined current rotation speed setting value and current rotation time setting value. Accurate parameter setting ensures the accuracy and stability of the rotation processing and helps to evenly distribute the glue in the optical fiber ring.

[0091] S502, with a preset time interval as a cycle, continuously record the rotation state fluctuation information and the ambient temperature fluctuation information, calculate the ambient temperature fluctuation amplitude value, and perform abnormal detection judgment at the same time. If it is judged to be abnormal, such as unstable rotation speed, excessive ambient temperature fluctuation, etc., an alarm is triggered so that the operator can intervene in time, and the rotating device stops rotating processing to avoid the production of defective products and protect the safety of equipment and materials. If it is not judged to be abnormal, the rotating device continues to rotate until the current rotation time setting value is reached, then stops rotating and notifies the subsequent process to perform the next step of operation.

[0092] This process ensures the smooth progress of the rotating processing and provides a guarantee for the smooth progress of the subsequent processes.

[0093] Further, based on step S502, the following steps are included:

[0094] S5021, setting an ambient temperature fluctuation threshold, continuously recording rotation state fluctuation information and ambient temperature fluctuation information at a preset time interval, and calculating the ambient temperature fluctuation amplitude value, wherein the rotation state fluctuation information includes the current actual rotation speed value and the current actual rotation time value.

[0095] This step can monitor the key parameters of the rotation processing in real time, including the rotation speed, rotation time and changes in ambient temperature, providing data support for subsequent abnormality detection. At the same time, setting the ambient temperature fluctuation threshold helps to accurately determine whether the ambient temperature fluctuation is within the normal range, ensuring the stability of the rotation processing environment.

[0096] S5022, the step of matching the current actual rotation speed value with the current rotation speed setting value within n consecutive sampling periods, includes the following formula:

[0097] |ω sp -ω pv |≥m

[0098] Among them, ω sp Indicates the current rotation speed setting value, ω pv Indicates the current actual value of the rotation speed. By comparing the difference between the set value and the actual value, it is possible to promptly find out whether the rotation speed is stable and whether there is an abnormality. If the absolute value of the difference between the current rotation speed set value and the current actual value of the rotation speed is greater than or equal to m, then proceed to step S5025, otherwise proceed to step S5026.

[0099] S5023, the step of matching the current actual rotation time value with the current rotation time setting value, this step is used to verify whether the rotation processing is completed as planned. If the current actual rotation time value is not equal to the current rotation time setting value, it indicates that the rotation processing may be delayed or completed ahead of schedule, and then the process proceeds to step S5025. On the contrary, if the two are equal, it indicates that the rotation processing is completed as planned, and then the process proceeds to step S5026.

[0100] S5024, a step of comparing the ambient temperature fluctuation amplitude value with the ambient temperature fluctuation threshold value. If the ambient temperature fluctuation amplitude value is not less than the ambient temperature fluctuation threshold value, proceed to step S5025, otherwise proceed to step S5026.

[0101] S5025, triggering an alarm, and at the same time the rotating device stops the rotating processing step.

[0102] This step is an emergency measure taken when an abnormal situation is detected, aiming to protect the safety of equipment and materials and avoid the production of defective products. By triggering an alarm, the operator can be reminded to intervene in time, and stopping the rotation process can prevent the abnormal situation from deteriorating further.

[0103] S5026, the rotating device continues to rotate until the current rotation time setting value is reached, then stops rotating and notifies the subsequent process to proceed to the next step of operation.

[0104] This step is carried out when all tests are normal, ensuring the smooth progress of the rotation process and providing a guarantee for the smooth progress of the subsequent processes. By stopping the rotation and notifying the subsequent processes, the smooth connection of the production process can be achieved and production efficiency can be improved.

[0105] Furthermore, the ambient temperature fluctuation information includes the maximum value of the ambient temperature of the functional area and the minimum value of the ambient temperature of the functional area. These two parameters together reflect the range of change of the ambient temperature during the rotation process. The ambient temperature fluctuation amplitude value intuitively reflects the stability of the ambient temperature, which is equal to the difference between the maximum value of the ambient temperature of the functional area and the minimum value of the ambient temperature of the functional area, including the following formula:

[0106] (tem max -tem min )≥tem0

[0107] Among them, tem max Indicates the maximum ambient temperature of the functional area, tem min It indicates the minimum value of the ambient temperature in the functional area, and tem0 indicates the ambient temperature fluctuation threshold.

[0108] This setting helps to promptly detect and handle abnormal fluctuations in ambient temperature, ensuring the stability of rotary processing and product quality.

[0109] Based on step S5026, the following steps are included:

[0110] 5 to 10 minutes before the rotating device finishes rotating, the rotating device will emit a prompt sound indicating that the rotation is about to end, and notify the next process in advance to make preparations for the process connection.

[0111] This step ensures the consistency and efficiency of the production process.

[0112] When the rotation is finished, the rotating device emits a rotation completion prompt sound and notifies the next process to proceed with the process docking steps.

[0113] This step effectively avoids the waiting time between processes and improves overall production efficiency.

[0114] If it is detected that the processed optical fiber ring to be rotated has not been taken out 10 minutes after the rotation is completed, the rotating device will emit a product retention prompt sound and notify the next step of the process.

[0115] This design aims to promptly detect and resolve product retention issues, prevent production delays or quality risks caused by long-term product retention, and ensure smooth production processes and stable product quality.

[0116] In addition, it should be noted that the current model parameters of the fiber optic ring to be rotated include the current fiber optic ring model information, the fiber optic ring frame outer diameter information and the fiber optic ring frame height information. This information provides accurate processing parameters for the rotating device, ensuring the accuracy and stability of the processing process. At the same time, it also provides strong support for the docking of subsequent processes and the traceability of product quality.
