Examples of the embodiments are shown in the drawings, where the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout.

[0037] In the description of the present invention, unless otherwise clearly defined, words such as setting, installation, connection, etc. should be understood in a broad sense, and those skilled in the art can reasonably determine the specific meanings of the above words in the present invention in combination with the specific content of the technical solution.

[0038] Refer to Figure 1 、 Figure 2 As shown in [relevant reference], a system for automatically fabricating fiber optic code humidity - sensitive is provided for the first - aspect embodiment of the present technical solution, including: workbench 100, fiber optic conveying device 200, positioning module 300, humidity - sensitive module 400, main control module 500; the workbench 100 serves as the installation and fixing platform for modules such as the fiber optic conveying device 200, positioning module 300, humidity - sensitive module 400, and main control module 500.

[0039] Specifically, the fiber optic conveying device 200 operates under the instruction of the main control module 500, and is used to drive the fiber optic 10 to move from one end of the workbench 100 to the other end. There is at least one fiber optic code 11 on the fiber optic 10. Figure 1Four optical fiber codes 11 are schematically shown; the positioning module 300 is used to detect the position information of the optical fiber code 11 and feedback it to the main control module 500, and the main control module 500 can then identify the specific horizontal position of the optical fiber code 11 on the workbench 100; the humidity-sensitizing module 400 has a humidity-sensitive material, and the humidity-sensitizing module 400 is provided with an electric fiber pressing rod 410 and a coating thickness control device 420. The humidity-sensitizing module 400 is a container for accommodating the humidity-sensitive material, such as a groove, etc. When the optical fiber 10 and the optical fiber code 11 are moving, they move horizontally and cannot directly contact the humidity-sensitive material. Therefore, the electric fiber pressing rod 410 can control the height of the optical fiber 10 and the optical fiber code 11 in the humidity-sensitizing module 400 to adhere to the humidity-sensitive material under the instruction of the main control module 100. Similarly, after the optical fiber 10 and the optical fiber code 11 come out of the humidity-sensitizing module 400, since the thickness of the adhered humidity-sensitive material is variable, the coating thickness control device 420 can control the coating thickness of the humidity-sensitive material after the optical fiber 10 and the optical fiber code 11 come out of the humidity-sensitizing module 400 under the instruction of the main control module 100; the main control module 500 is electrically connected to the optical fiber conveying device 200, the positioning module 300, the electric fiber pressing rod 410 and the coating thickness control device 420 respectively, and is used to control the actions of the optical fiber conveying device 200, the optical fiber conveying device 200, the electric fiber pressing rod 410 and the coating thickness control device 420 according to the position information of the optical fiber code 11 fed back by the positioning module 300.

[0040] As described above, this solution uses the positioning module 300 to detect the position of the optical fiber code 11 in real time, and the main control module 500 accurately operates the optical fiber conveying device 200, the electric fiber pressing rod 410 and the coating thickness control device 420 of the humidity-sensitizing module 400 respectively, realizing standardized processing while realizing humidity-sensitizing processing.

[0041] As Figure 1As shown, in some embodiments of the first aspect of the present invention, the humidity - sensitive module 400 includes a solution immersion tank 401, a solution coating tank 402, and a solid coating tank 403 arranged at intervals in sequence. The solution immersion tank 401, the solution coating tank 402, and the solid coating tank 403 are respectively used to accommodate humidity - sensitive materials in different states. On both sides of the solution immersion tank 401, the solution coating tank 402, and the solid coating tank 403, there are first fiber - passing holes 404 for the optical fiber 10 to pass through, so that the optical fiber 10 can freely pass through each groove. Correspondingly, there are three groups of electric fiber - pressing rods 410, which are respectively located in the solution immersion tank 401, the solution coating tank 402, and the solid coating tank 403, and respectively control the optical fiber 10 and the optical fiber code 11 to press down and adhere to the humidity - sensitive material in each groove. The solution immersion tank 401 is used for long - time liquid immersion, the solution coating tank 402 is used for short - time coating, and the solid coating tank 403 is used for short - time coating of solids or powders. The coating thickness control device 420 has two groups and is respectively located on the outlet sides of the solution coating tank 402 and the solid coating tank 403, and respectively controls the thickness of the optical fiber 10 and the optical fiber code 11 after solution coating and solid coating.

[0042] It should be noted that the humidity - sensitive module 400 including three groups of grooves such as the solution immersion tank 401, the solution coating tank 402, and the solid coating tank 403 is only one embodiment of the present technical solution. One or two of the above - mentioned grooves can be set according to different needs, which is also within the protection scope of the present technical solution.

[0043] Furthermore, in some embodiments of the first aspect of the present invention, each group of electric fiber - pressing rods 410 has two and is distributed on both inner sides of the solution immersion tank 401, the solution coating tank 402, and the solid coating tank 403. This design can make the optical fiber code 11 located at the center of the groove. When the electric fiber - pressing rods 410 on both sides press down, it can ensure that the optical fiber code 11 completely enters the humidity - sensitive material. Compared with a single electric fiber - pressing rod 410, the two - side pressing structure can improve the accuracy of coating the optical fiber code 11.

[0044] Particularly, in some embodiments of the first aspect of the present invention, the coating thickness control device 420 adopts an automatically - adjustable aperture baffle. Figure 1 What is shown is two upper and lower baffles with adjustable spacing. By adjusting the spacing between the two baffles, the aperture when the optical fiber 10 passes through can be controlled, and the coating thickness can be controlled by using the aperture size. The automatically - adjustable aperture baffle can adopt driving methods such as motors, electromagnets, and hydraulics to achieve power output.

[0045] Combined with Figure 1As shown, in some embodiments of the first aspect of the present invention, the optical fiber conveying device 200 is a first electric roller 210 and a second electric roller 220 respectively arranged at both ends of the workbench 100. The optical fiber 10 is wound around the first electric roller 210 and the second electric roller 220. When the first electric roller 210 and the second electric roller 220 rotate, the optical fiber 10 can be driven to be conveyed forward.

[0046] In some embodiments of the first aspect of the present invention, the positioning module 300 is a video monitoring module. The camera of the video monitoring module can monitor the specific position of the optical fiber code 11 because the position color of the optical fiber code 11 is darker than other parts of the optical fiber 10. Of course, other existing positioning modules can also be used to detect the position of the optical fiber code 11, such as proximity switches, infrared pair sensors, etc.

[0047] This solution is not limited to humidity sensitization, but also has temperature desensitization. In some embodiments of the first aspect of the present invention, a drying tank 600 is further included. Second optical fiber passing holes 601 for the optical fiber 10 to pass through are provided on both sides of the drying tank 600. The second optical fiber passing holes 601 can enable the optical fiber 10 to freely pass through each groove. A drying module 602 that irradiates downward is provided at the top of the drying tank 600. Through the heating of the drying module 602, the humidity-sensitive material on the outer surface of the optical fiber code 11 can be cured, reducing the wavelength characteristic change caused by the later temperature change, and at the same time improving the efficiency compared with natural air drying.

[0048] Since coating is not required for temperature desensitization, but stress loading is needed, in some embodiments of the first aspect of the present invention, one end of the optical fiber 10 is connected to a wavelength detection module 700, and the other end is connected to a tensiometer 800. An electric clamping device 900 for fixing the optical fiber 10 is provided on the front side of the drying tank 600. The wavelength detection module 700, the tensiometer 800, and the electric clamping device 900 are respectively electrically connected to the main control module 500. Under the command of the main control module 500, the electric clamping device 900 can be controlled to clamp the optical fiber 10, stress is loaded by the tensiometer 800, and finally the wavelength change of the optical fiber code 11 under different temperature and stress conditions is detected by the wavelength detection module 700.

[0049] In addition, in some embodiments of the first aspect of the present invention, the drying module 602 is a drying lamp, which has the advantage of directional irradiation heating. Of course, other electric heating devices can also be used without considering energy consumption.

[0050] As Figure 3 shown, a method for automatically fabricating humidity-sensitized optical fiber codes according to an embodiment of the second aspect of the present invention is applied to the system for automatically fabricating humidity-sensitized optical fiber codes in the above embodiments. The method for automatically fabricating humidity-sensitized optical fiber codes includes the following steps

[0051] The main control module 500 outputs motion instructions, and the optical fiber conveying device 200 drives the optical fiber 10 to move from one end of the workbench 100 to the other end.

[0052] The positioning module 300 real-time detects the position information of the optical fiber code 11 and feeds it back to the main control module 500.

[0053] The main control module 500 controls the optical fiber conveying device 200 to convey the optical fiber code 11 into the humidity-sensitizing module 400 for sensitization operation according to the position information of the optical fiber code 11 fed back by the positioning module 300. The electric fiber pressing rod 410 controls the height of the optical fiber 10 and the optical fiber code 11 in the humidity-sensitizing module 400 to adhere the humidity-sensitive material, and the coating thickness control device 420 controls the coating thickness of the humidity-sensitive material after the optical fiber 10 and the optical fiber code 11 come out of the humidity-sensitizing module 400.

[0054] It can be seen that this solution uses the positioning module to real-time detect the position of the optical fiber code, and the main control module 500 accurately operates the electric fiber pressing rod 410 of the optical fiber conveying device 200 and the coating thickness control device 420 of the humidity-sensitizing module 400, realizing standardized processing while realizing humidity-sensitizing processing.
