Description

Technical Field

[0001] This invention relates to the field of optical fiber processing equipment technology, and in particular to an automatically compensated optical fiber tapering device and method. Background Technology

[0002] Fiber taper technology is a processing technique that softens optical fibers by heating and applying tension to reduce the diameter and length of a local area of ​​the fiber. It is a key technology for manufacturing core optical devices such as fiber couplers, fiber splitters, and fiber sensors. The existing fiber tapering device mainly relies on manual setting of heating parameters (such as fuel flow rate, heating temperature), transmission speed and fixed pressure. The processing process lacks real-time monitoring and dynamic compensation mechanism, and has the following technical defects: (1) Low processing accuracy and poor uniformity: manual control cannot accurately match the degree of fiber softening and tapering speed, which can easily lead to problems such as uneven fiber core diameter and tapered length deviation, affecting the optical performance of optical devices (such as insertion loss and splitting ratio deviation); (2) Low yield: when the heating flame intensity fluctuates, the transmission speed is unstable or the fixed pressure is uneven, unqualified areas (NG points) are easily generated. The existing device cannot identify and compensate in real time, and manual rework is required, resulting in a yield of less than 60%; (3) High degree of manual intervention and low efficiency: the processing process requires a dedicated person to monitor the fiber morphology and adjust parameters, which cannot realize automated continuous production and adapt to the needs of large-scale production; (4) Lack of closed-loop control: each component (fixing device, heating device, transmission device) works independently without a collaborative linkage mechanism, and cannot dynamically adjust parameters according to processing deviation, which restricts processing stability.

[0003] Therefore, how to design a fiber optic taper device with real-time monitoring, intelligent linkage and automatic compensation functions is a technical problem to be solved. Summary of the Invention

[0053] Exemplary embodiments of the present disclosure will now be described in more detail with reference to the accompanying drawings. While exemplary embodiments of the present disclosure are shown in the drawings, it should be understood that the present disclosure may be implemented in various forms and should not be limited to the embodiments set forth herein. Rather, these embodiments are provided so that this disclosure will be thorough and complete, and will fully convey the scope of the disclosure to those skilled in the art.

They are used only for the convenience of describing the invention and for simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on the invention. Furthermore, the terms "first," "second," and "third" are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0055] Furthermore, the technical features involved in the different embodiments of the present invention described below can be combined with each other as long as they do not conflict with each other.

[0056] Reference Figure 1 This embodiment discloses an automatically compensated fiber taper device, including: an adaptive fixing system, a first heating device, an optical monitoring system, a second heating device, and a fixing and transmission component.

[0057] In this embodiment, the adaptive fixing system includes an adaptive fixing device 1 and a fixing device central control system 2, which performs adaptive fixing and transmission of the processed optical fiber 13 in the device. Figure 2 The specific structure of the adaptive fixed system is shown:

[0058] Specifically, the adaptive fixing device 1 includes a fixed base 1-1, a first optical fiber receiving base 1-2, a second optical fiber receiving base 1-3, a first pressure sensor 1-4, a second pressure sensor 1-5, a first force-applying base 1-6, a second force-applying base 1-7, and a horizontal pressure bar 1-8. The fixed base 1-1 is fixed to the bottom horizontal platform, and its horizontality needs to be adjusted and checked regularly according to the actual situation. The first optical fiber receiving base 1-2 and the second optical fiber receiving base 1-3 are both fixed to the upper surface of the fixed base 1-1. The first pressure sensor 1-4 and the second pressure sensor 1-5 are respectively set on the first optical fiber receiving base 1-2 and the second optical fiber receiving base 1-3. The optical fiber receiving bases (1-2 and 1-3) need to be adjusted regularly to ensure that they are always strictly horizontal, and the pressure sensors mounted on them also need to be adjusted regularly to ensure the accuracy and consistency of the pressure detection values. The first force-applying base 1-6 and the second force-applying base 1-7 are respectively set directly above the first optical fiber receiving base 1-2 and the second optical fiber receiving base 1-3. These two components need to be adjusted regularly for horizontality and flatness. The two ends of the horizontal pressure rod 1-8 are respectively set on the upper surface of the first force-applying base 1-6 and the second force-applying base 1-7. During the fiber taper process, the central control system 2 of the fixing device generates an initial pressure command based on the relevant process parameters of the fiber being processed. During the transmission process, it receives pressure data from the first pressure sensor 1-4 and / or the second pressure sensor 1-5 and updates the pressure command. Then, based on the updated pressure command, it generates pressure data and applies pressure to the two force-applying bases, thereby achieving adaptive fixing and transmission of the fiber being processed.

[0059] In this embodiment, the first heating device includes a first heating chamber 3 and a first heating control chamber 4. The main function of the first heating device is to perform the first heating on the optical fiber 13 to be processed and tapered. Figure 3 The specific structure of the first heating device is shown:

[0060] The first heating chamber 3 includes a delivery pipe 3-1, a gas nozzle 3-2, and a heating zone 3-3. The gas nozzle 3-2 is located inside the heating zone 3-3, and the heating zone 3-3 is connected to the first heating control chamber 4 via the delivery pipe 3-1. Specifically, the first heating chamber 3 is mainly used to heat the fiber to be tapered, softening the target fiber so that it can be processed into the target fiber. The first heating control chamber 4 mainly controls the temperature and environment of the fuel input to the tapering system according to the instructions of the central control system (not shown in the figure), such as monitoring the fuel delivery speed, delivery concentration, ignition time, and fuel balance, to ensure that the environment of the heating zone 3-3 is adjustable according to requirements.

[0061] In this embodiment, the optical monitoring system includes a monitoring light source 5, a first detector 6, a second detector 7, and an optical monitoring system control room 12, which is used to perform optical detection on the processed optical fiber 13 after the first heating to obtain the tapering process data of the processed optical fiber 13. Figure 4 The diagram illustrates the specific structure and data acquisition process of the optical monitoring system: The central element is a tapered optical fiber. When the fiber is transmitted to the optical monitoring system, two optical detectors compare the reflected / transmitted beam with a reference position / time, collect data, and perform data analysis in the central control room 12 of the optical monitoring system. Based on the analysis results, the data is uploaded to the central control system to control the entire device in tandem for correction. Specifically, the optical detection process is as follows: the monitoring light source 5 emits a beam that enters the processed optical fiber 13. Part of the beam is reflected, and part is projected. The first detector 6 collects the reflected beam to obtain reflected light data, and the second detector 7 collects the transmitted beam to obtain transmitted light data. In a preferred embodiment, the first detector 6 and the second detector 7 can be high-speed cameras.

[0062] After obtaining the reflected light data and transmitted light data, the optical monitoring system control room 12 performs data analysis on the position / time information dimensions based on the collected data to obtain the tapering process data of the processed optical fiber 13. Then, the tapering process data is compared with the reference tapering data to obtain the first-pass yield of the optical fiber tapering process. If there is a deviation, reprocessing is required. The deviation information is fed back to the central control system. The central control system controls the feeding speed by controlling the pressure of the adaptive fixing device, controls the flame intensity by controlling the fuel feeding speed and concentration in the heating chamber, and fine-tunes the conveying speed by controlling the central control system of the fixed conveying device.

[0063] When uneven fiber core diameter occurs during fiber straightening due to factors such as heating flame or precision motor speed, the monitoring system collects the core diameter information and feeds it back to the central control system. The central control system then controls the high-precision motor / slide rail in the second heating chamber to reheat the fiber at the corresponding non-compliant (NG) points, bringing it back to standard. (Refer to...) Figure 4 For example, the transmitted beam L1 corresponding to the normal core diameter is located at position a on the second detector 7, the transmitted beam L2 corresponding to the fiber with a larger core diameter is located at position b, and the transmitted beam L3 corresponding to the fiber with a severely larger core diameter is located at position c.

[0064] In this embodiment, the second heating device performs a second heating on the tapering deviation area of ​​the optical fiber 13 being processed, based on the tapering process data. The tapering deviation area is calculated using the tapering process data, and the second heating process is as follows:

[0065] The second heating command is generated based on the tapering process data; the second heating control room 9 controls the moving component 14 to move the second heating chamber to the tapering deviation area based on the second heating command; the second heating control room 9 controls the heating temperature of the second heating chamber 8 according to the second heating command, so that the processed optical fiber meets the processing standard.

[0066] In a preferred embodiment, the moving component 14 is a high-precision motor / slide rail. After receiving the instruction from the second heating control chamber 9, it precisely moves the second heating chamber 8 to the optical fiber that needs to be reprocessed to perform secondary heating and drawing.

[0067] In this embodiment, after the optical fiber 13 is drawn, the fixed conveying assembly performs pressure fixation and transport. Specifically, the fixed conveying assembly includes a fixed conveying device 10 and a horizontal fixed base 11 for fixation. The structure of the fixed conveying device 10 is similar to that of the adaptive fixing device, except that the receiving base and the force-applying base of the fixed conveying device 10 are both wrapped with a uniformly rotating flat conveyor belt. The central control system is mainly used to control the conveying speed of the conveyor belt according to the instructions of the central control system. The horizontal fixed base 11 provides horizontal support for the fixed conveying device 10.

[0068] In this embodiment, the central control system is used to control the central controllers corresponding to the fixed device central control system 2, the first heating central control room 4, the optical monitoring system central control room 12, the second heating central control room 9, and the fixed conveying device 10. The output commands of the central control system include: fuel delivery speed, delivery concentration, ignition time, fuel balance monitoring, and precise movement.

[0070] (1) This application sets up an optical monitoring system and two heating devices. Through real-time optical monitoring and dual heating chambers working together to compensate, it can accurately identify and correct problems such as core diameter deviation and uneven taper area, and greatly improve the yield of the first batch. At the same time, adaptive pressure regulation and transmission rate matching reduce the diameter and length deviation of the fiber taper area, so the processing uniformity is significantly better than that of the existing devices.

[0071] (2) A central control system is set up for multiple key structures, which links the adaptive fixing device, heating device, monitoring system and transmission device to form a closed-loop control of "monitoring-judgment-control-compensation".

At the same time, each central control system can flexibly adjust the reference parameters (pressure, temperature, rate, etc.) to adapt to the tapering requirements of different specifications of optical fibers, and has a wide range of applicable scenarios.
