Description

Technical Field

[0001] The present invention relates to the field of optical fiber couplers, and in particular to the field of light field modeling technology, and specifically to an optical fiber coupler tapering optimization system based on light field modeling and embedded drive. Background Art

[0002] As the global industrial automation transition accelerates, demand for fiber optic couplers, key components in the communications and information technology sectors, continues to rise. This is particularly true in China, one of the world's major fiber optic coupler consumer markets, where the domestic industry is at a critical stage of transitioning from traditional manual production to intelligent, automated manufacturing.

[0003] At present, the main reason for the long production cycle of the traditional fiber optic coupler preparation process is the manual stripping of the optical fiber coating. In the traditional optical fiber coupler production industry, the stripping of the optical fiber coating is complicated, the optical fiber shelving process is cumbersome, the temperature control of the fusion taper process is imprecise and relies on manual labor, the stripping force and angle stability are poor, and the worker training cost is high and the training cycle is long; the main reason why the drawing accuracy of the traditional fusion taper optical fiber coupler automated production system cannot be stably improved is that after reaching a certain splitting ratio, the device stops heating and tapering, and the final coupling degree is improved by the residual heat of the flame. However, the optical fiber taper process is easily affected by environmental parameters. Therefore, the taper length and geometric shape are different during the taper process, and the improvement of the splitting ratio accuracy cannot be stable. Summary of the Invention

[0004] In response to the shortcomings of the existing technology, the present invention provides an optical fiber coupler taper optimization system with light field modeling and embedded drive. The production cycle is reduced by setting an automatic optical fiber coating stripping module, and the system stability is improved and labor costs are effectively reduced by setting the color of the automated optical fiber taper control module. The splitting ratio accuracy is improved by setting a fused taper temperature control module.

[0005] The present invention is achieved through the following technical solutions: a light field modeling and embedded-driven fiber coupler taper optimization system, including an automatic fiber coating stripping module, an automated fiber taper control module, and a fused taper temperature control module.

[0006] Preferably, the automatic stripping module for optical fiber coating is controlled by a six-axis drive plate, and deviation correction feedback is introduced, and error analysis using the k-nearest neighbor method is adopted, which is adaptable to the potential function f(x), can reduce the variance, and improve the stripping accuracy of the stripping device.

[0007] As a priority, a dual-layer algorithm was enabled to enhance its software adaptability, shortening the fiber optic coupler production cycle by 61.9%.

[0008] As a preferred option, the automated fiber taper control module adopts an industrial computer and a six-axis drive, and uses the RS-485 bus to ensure the stability and isolation of data transmission between the industrial computer and the six-axis drive. A framework is built with the industrial computer as the host computer responsible for the calculation and processing of the data flow, and the six-axis drive as the control core to isolate the computing tasks and control tasks, which facilitates subsequent task expansion and equipment maintenance.

[0009] Preferably, the fused taper temperature control module adjusts various parameters of the taper before the cessation of firing to compensate, controls various parameters before the cessation of firing to remain relatively uniform, and improves the stability of the coupling degree through the residual temperature after the cessation of firing.

[0010] The algorithm theory of using rotation matrix instead of Euler angle difference is used to represent the rotation state of the optical fiber, which simplifies the data processing process and improves the stripping speed.

[0011] Preferably, a light source is connected to the fixed end of the optical fiber reel, and two optical fibers are sequentially drawn out from the movable end of the optical fiber reel. After the coating layers of the two optical fibers are stripped off in the first smooth areas, the first smooth areas of the two optical fibers are sequentially placed on the taper mechanism, wherein the two fractures close to the first smooth area are placed on two optical power detection probes respectively. While the fitting parts of the first smooth areas of the two fiber cores are heated by the flame head, the optical fiber clamping seats at both ends move in opposite directions.

[0012] The beneficial effects of the present invention are as follows: the production cycle is reduced by setting up an automatic optical fiber coating stripping module; the system stability is improved and labor costs are effectively reduced by setting up an automatic optical fiber taper control module; the splitting ratio accuracy is improved by setting up a fused taper temperature control module; the automatic optical fiber taper control module adopts an industrial computer and a six-axis drive, and uses the RS-485 bus to ensure the stability and isolation of data transmission between the industrial computer and the six-axis drive, and builds a framework for isolating computing tasks and control tasks with the industrial computer as the host computer responsible for calculating and processing data streams and the six-axis drive as the control core, which is convenient for later task expansion and equipment maintenance. DETAILED DESCRIPTION

[0013] In order to clearly illustrate the technical features of this solution, this solution is described below through specific implementation methods.

[0014] The optical fiber coupler taper optimization system of the present invention with light field modeling and embedded drive includes an optical fiber coating automatic stripping module, an automated optical fiber taper control module, and a fused taper temperature control module.

[0015] The main reason for the long production cycle of the traditional fiber optic coupler preparation process is the manual stripping of the optical fiber coating. The optical fiber coating automatic stripping module includes an optical fiber coating automatic stripping device. The optical fiber coating automatic stripping device is controlled by an independently developed six-axis drive board, and introduces deviation correction feedback. The error analysis uses the k-nearest neighbor method, which has great adaptability to the potential function f(x), can greatly reduce the variance, and can improve the stripping accuracy of the stripping device.

[0016] In order to solve the problems of complex data processing and slow response speed in traditional optical fiber stripping using linear interpolation algorithms, the upgraded fully automatic optical fiber taper machine is equipped with a double-layer algorithm using the rotation matrix instead of the Euler angle difference algorithm theory to enhance its software adaptability and shorten the optical fiber coupler production cycle by 61.9%.

[0017] In the traditional fiber optic coupler production industry, the operation of stripping the optical fiber coating is complicated, the optical fiber shelving process is cumbersome, the temperature control of the fusion taper process is imprecise and relies on manual labor, the stripping force and angle stability are poor, and the worker training cost is high and the training cycle is long.

[0018] Therefore, by ingeniously combining mechanical design and automation technology, and further researching key technologies for automated fiber taper drawing, we innovatively implemented an automated fiber taper control system using an industrial computer and a proprietary six-axis drive. The RS-485 bus ensures stable and isolated data transmission between the industrial computer and the six-axis drive. A framework was established, with the industrial computer as the host computer responsible for calculating and processing the data stream, and the six-axis drive as the core control, isolating computing and control tasks. This facilitates future task expansion and equipment maintenance. This leverages the powerful computing power of the industrial computer and the stable control capabilities of the six-axis drive, improving system stability and effectively reducing labor costs by approximately 40%.

[0019] The main reason why the drawing accuracy of traditional fused-taper fiber coupler automated production systems cannot be steadily improved is that after reaching a certain splitting ratio, the device stops heating and tapering, and uses the residual heat of the flame to finally improve the coupling degree. However, the fiber tapering process is easily affected by environmental parameters. Therefore, the taper length and geometric shape of the taper are different during the tapering process, and the improvement of the splitting ratio accuracy cannot be stable.

[0020] By adjusting the various parameters of the tapered fiber before the closure, compensation is achieved, ensuring that all parameters remain relatively uniform. After the closure, the residual heat generated by the tapered fiber significantly increases the stability of the coupling. Model calculations show that, using a single-mode fiber coupling with a 50% splitting ratio as an example, the average splitting ratio can be increased from 48.12% to 49.91% using the traditional tapered method.

[0021] Of course, the above description is not limited to the above examples. The technical features not described in the present invention can be achieved by or by adopting existing technologies, which will not be described here. The above embodiments are only used to illustrate the technical solutions of the present invention and are not limitations of the present invention.

Ordinary technicians in this field should understand that changes, modifications, additions or substitutions made by ordinary technicians in this technical field within the essential scope of the present invention do not depart from the purpose of the present invention and should also fall within the scope of protection of the claims of the present invention.
