In the embodiment of the present application, the cleaning number value is set to 3 times. Among them, the side of the fiber stripping section is wiped in one direction, and the fiber end face also needs to be cleaned and wiped. After each wiping is completed, it is necessary to wait for the alcohol to completely evaporate before wiping again or proceeding to the next step.

[0064] Step S24: After the cleaning and wiping is completed, it is determined whether the stripped section of the optical fiber to be connected is clean. If it is clean, a cleaning verification pass signal is output.

[0065] Specifically, a high-definition camera is used to photograph the stripped section of the optical fiber to be connected to determine whether there are impurities, dust, or oil on the side and end face of the stripped section of the optical fiber to be connected. If so, the optical fiber is cleaned again until there are no impurities, dust, or oil, and then a cleaning verification pass signal is output.

[0066] Step S25, after receiving the cleaning verification pass signal, obtain the optical fiber cleaver, adjust the knife position of the optical fiber cleaver according to the structural size information of the optical fiber to be connected, perform the cutting operation after adjustment, and output a cutting completion signal after the operation is completed.

[0067] Step S26, after receiving the cutting completion signal, the optical fiber end face of the optical fiber to be connected is detected based on the magnifying glass to see if it is flat. If it is flat, a cutting verification pass signal is output. If it is not flat, the cutting is repeated until the optical fiber end face of the optical fiber to be connected is flat, and then a cutting verification pass signal is output.

The alignment parameter is dynamically adjusted based on the environmental offset parameter information to obtain alignment compensation parameter information. Step S3 specifically includes:

[0079] Step S35 , dynamically adjusting the compensation parameters of the pigtail terminal of the optical fiber pigtail according to the environmental offset parameter information to obtain alignment compensation parameter information.

[0080] In actual use, when the temperature changes greatly, the thermal expansion and contraction of the optical fiber material will cause alignment deviation, reduce the accuracy of optical fiber docking, and increase the fusion loss.

[0081] The temperature of the optical fiber to be connected and the optical fiber pigtail is detected by a temperature sensor, and a thermal expansion model database is created to respectively analyze the temperature effect on the offset of the optical fiber to be connected and the optical fiber pigtail to obtain environmental offset parameter information. The compensation parameters of the optical fiber pigtail terminal are adjusted according to the environmental offset parameter information to obtain alignment compensation parameter information. The alignment compensation parameter information is used for temperature compensation in the subsequent alignment process of the optical fiber to be connected and the optical fiber pigtail, thereby improving the accuracy of optical fiber docking control.

[0082] Reference Figure 1 In step S4, calibration is performed based on the acquisition time of the environment detection module, the acquisition time of the high-definition camera, and the positioning time of the positioning sensor.

[0084] Step S42 , based on the temperature acquisition time, the image acquisition time and the positioning time, the real-time time calibration of each data is performed, and after the calibration is completed, a multimodal data time calibration signal is output.

[0085] In the embodiment of the present application, time calibration is performed on multi-source data such as temperature acquisition time, image acquisition time, and positioning time during the fiber optic docking process to ensure the consistency of data from different sources in the time dimension, provide an accurate time reference for subsequent fiber optic docking, and thereby improve the accuracy of fiber optic docking control.

[0086] Reference Figure 1 In step S5, after receiving the multimodal data time calibration signal, the optical fiber end face of the optical fiber to be connected is positioned to obtain the core position information. Combining the alignment compensation parameter information and the core position information, the optical fiber clamp clamps the pigtail terminal and aligns it with the optical fiber end face and outputs an alignment completion signal. Step S5 specifically includes:

[0087] Step S51: After receiving the multimodal data time calibration signal, the exposed optical fiber end face of the optical fiber to be connected is positioned based on the grating positioning technology and the fiber core position information is output.

[0088] In practical applications, grating positioning technology utilizes the physical properties of gratings to achieve precise position detection. A grating is a device with a periodic structure that produces a series of light intensity variations distributed according to a specific pattern. In positioning systems, gratings are often used as sensing elements for displacement measurement. The core principle of grating positioning systems is based on the diffraction and interference phenomena of light. When a beam of monochromatic light strikes a grating, the periodic structure of the grating causes diffraction in the optical fiber, forming a series of diffraction fibers. After passing through a specific optical system, these diffraction fibers produce alternating light and dark interference fringes. By detecting the changes in these interference fringes, the displacement of an object can be accurately measured. A grating positioning system consists of two components: a grating scale and a grating readhead. The grating scale is engraved with numerous fine lines with very uniform spacing, forming the periodic structure of the grating. The grating readhead contains components such as a light source, a lens, and a photodetector. When the grating scale moves, the photodetector in the grating readhead detects the changes in the interference fringes and converts them into electrical signals. After processing, these electrical signals can be converted into digital signals, thereby obtaining the precise position information of the object. The grating positioning system has a high accuracy, which can reach the micron or even sub-micron level.

[0092] Step S55 , adjusting the preliminary planned path information of the fixture based on the alignment compensation parameter information to obtain the fixture movement path information.

[0093] In step S56 , based on the fixture movement path information, the optical fiber fixture clamps the optical fiber pigtail and moves it to align the pigtail terminal of the optical fiber pigtail with the optical fiber end face of the optical fiber to be connected, and outputs an alignment completion signal.

[0094] Reference Figure 1 In step S6, after receiving the alignment completion signal, the optical fiber end face is photographed based on a high-definition camera to verify whether the optical fiber end face and the pigtail terminal are aligned. If they are aligned, an alignment verification success signal is output. Step S6 specifically includes:

[0095] Step S61: After receiving the alignment completion signal, the fiber end face of the optical fiber to be connected is photographed at multiple angles using a high-definition camera to obtain multiple multi-angle fiber end face photographing images.

[0096] Step S62, based on the image information of the optical fiber end faces taken at each multi-angle, verify whether the optical fiber end face of the optical fiber to be connected is aligned with the fiber pigtail terminal of the optical fiber pigtail, and if the alignment criterion is correct, output an alignment verification success signal; if the alignment criterion is correct, move the optical fiber clamp based on the image information of the optical fiber end faces taken at each multi-angle, and the optical fiber clamp clamps the fiber pigtail terminal and adjusts it until the optical fiber end face of the optical fiber to be connected is aligned with the fiber pigtail terminal of the optical fiber pigtail, and output an alignment verification success signal.
