Description

Technical Field

[0001] This utility model belongs to the field of optical fiber manufacturing technology, and in particular relates to an online intelligent identification system for optical fiber production. Background Technology

[0002] Currently, optical fibers are widely used in communications, sensing, and medical fields. With the rapid growth of market demand, the types and specifications of optical fibers are increasing, placing ever higher demands on quality control and marking accuracy in the fiber manufacturing process. However, most optical fibers on the market have similar outer diameters and are transparent, making it impossible to directly distinguish fiber types by appearance. Furthermore, existing fiber defect removal methods carry the risk of missed or incorrect cuts, presenting the following problems:

[0003] 1. Difficulty in identification: Mass-produced optical fibers cannot be quickly distinguished from different types or production batches during subsequent use, which can easily lead to confusion at the construction site.

[0004] 2. Difficulty in quality control: Although most internal and external defects in optical fibers (such as bubbles inside the fiber, cladding diameter, coating diameter, coating particles, and bubbles on the outside of the fiber) can be recorded online during the optical fiber production process, and the corresponding drawing positions can be recorded, there are no special markings on the surface of the optical fiber. The screening process requires the algorithm to calculate the location of defect removal, which involves errors in testing equipment, metering errors between equipment, equipment malfunctions, and human operation errors, resulting in high quality risks.

[0005] 3. Key indicators cannot be identified: The concentricity error of the coating cannot be identified online. It needs to be screened and cut according to the test results and production experience, which affects production efficiency and quality.

[0006] 4. Insufficient traceability: The inability to trace product batches of optical fibers increases the difficulty of quality management.

[0007] 5. Insufficient brand promotion: The lack of direct brand logos on the surface of the optical fiber is not conducive to enhancing the company's image and market competitiveness.

[0008] Traditional labeling methods, which typically rely on external labels or packaging markings, suffer from problems such as easy detachment, lack of durability, and low efficiency. Utility Model Content

A second solenoid valve is installed on the ink pipe. Both the gas supply device and the second solenoid valve are electrically connected to the control system. The color inks in the multiple inkjet units are all of different colors.

[0013] Furthermore, each of the coloring ink cans is provided with a filling port on its top, and the filling port is provided with a sealing cap.

[0014] Furthermore, the gas pressure pipeline is located at the top of the coloring ink tank, and the ink pipeline is located at the bottom of the ink pipeline; the second solenoid valve is positioned close to the coloring ink tank.

[0015] Furthermore, each inkjet unit is equipped with a pipeline cleaning device, each pipeline cleaning device including an air inlet pipe and an air outlet pipe.

Detailed Implementation

[0026] The specific embodiments of this utility model are described below to enable those skilled in the art to understand this utility model. However, it should be understood that this utility model is not limited to the scope of the specific embodiments. For those skilled in the art, as long as various changes are within the spirit and scope of this utility model as defined and determined by the appended claims, these changes are obvious. All inventions utilizing the concept of this utility model are protected.

[0027] like Figures 1-3As shown, this utility model provides an online intelligent identification system 100 for optical fiber production, which includes a control system 1 and multiple inkjet devices 2 electrically connected to the control system 1. The control system 1 is electrically connected to a bare fiber diameter gauge 3, a convexity and concavity detector 4, a bubble detector 5, a coating diameter gauge 6, and an optical fiber coating concentricity detection device 7 on the optical fiber production line.

[0028] Each inkjet device 2 includes a color ink tank 21 containing color ink. A gas pressure pipe 22 and an ink pipe 23 are connected to the color ink tank 21. The gas pressure pipe 22 is connected to a gas supply device 24. An inkjet printhead 25 is located at the end of the ink pipe 23, with the ink nozzle of the printhead 25 facing the optical fiber. A second solenoid valve 26 is located on the ink pipe 23. Both the gas supply device 24 and the second solenoid valve 26 are electrically connected to the control system 1. The color inks in the multiple inkjet devices 2 are all of different colors.

[0029] The gas pressure pipeline 22 is equipped with a digital pressure gauge 9 and a first solenoid valve 10, which are electrically connected to the control system 1. The digital pressure gauge 9 is used to monitor the gas pressure in the color ink tank 21 in real time. When the gas pressure in the color ink tank 21 reaches the preset pressure, the gas supply device 24 and the first solenoid valve 10 are shut off to prevent the printing effect of the inkjet printhead 25 from being affected by excessively high gas pressure in the color ink tank 21.

[0030] The working process of the online intelligent marking system 100 for optical fiber production is as follows: The bare fiber diameter gauge 3, the convexity / concaveness detector 4, the bubble detector 5, the coating diameter gauge 6, and the optical fiber coating concentricity detection equipment 7 on the optical fiber production line respectively detect the cladding diameter, coating particles, coating bubbles, and optical fiber coating concentricity. The control system 1, based on parameters such as cladding diameter, coating particles, coating bubbles, and optical fiber coating concentricity, controls multiple inkjet devices 2 to perform online marking on the optical fiber, directly generating marking information on the fiber surface. This facilitates identification and differentiation in subsequent processes, preventing missed or incorrect cutting of fiber defects. For example, when the bubble detector 5 detects bubbles in the fiber coating, the control system 1 controls the inkjet device 2, which can spray red coloring ink, to operate, opening the second solenoid valve 26. Under air pressure, the red coloring ink enters the inkjet printhead 25 through the ink pipe 23. The inkjet printhead 25 sprays the red coloring ink onto the fiber surface to form a red marking layer, indicating the presence of a bubble defect in this section of the fiber. When the bare fiber diameter gauge 3 detects that the cladding diameter of the optical fiber does not meet the pre-approval parameters, the control system 1 controls the inkjet device 2, which can spray ink of other colors, to work and mark the optical fiber.

[0031] Preferably, each of the coloring ink cans 21 is provided with a filling port 27 on its top, and a sealing cap 28 is provided on the filling port 27. The filling port 27 facilitates the addition of coloring ink into the coloring ink can 21, and the sealing cap 28 can prevent the coloring ink from evaporating.

[0032] The gas pressure pipe 22 is located at the top of the coloring ink tank 21, and the ink pipe 23 is located at the bottom of the ink pipe 23. This arrangement facilitates the complete use of coloring ink in the coloring ink tank 21, reducing ink residue. The second solenoid valve 26 is positioned close to the coloring ink tank 21 to facilitate the subsequent installation of the pipe cleaning device 8.

[0033] Specifically, each inkjet device 2 is matched with a pipeline cleaning device 8. Each pipeline cleaning device 8 includes an air inlet pipe 81 and an air outlet pipe 82. One end of the air inlet pipe 81 is connected to the external environment, and the other end is connected to the inlet end of the ink pipeline 23. A third solenoid valve 83 and an air pump 84 are provided on the air inlet pipe 81. One end of the air outlet pipe 82 is connected to the outlet end of the ink pipeline 23, and the other end is connected to a waste ink collection bucket 85. A fourth solenoid valve 86 is provided on the air outlet pipe 82.

[0034] When cleaning of the ink pipe 23 is required, the control system 1 closes the second solenoid valve 26 and the inkjet printhead 25, and then opens the third solenoid valve 83, the air pump 84, and the fourth solenoid valve 86. The air pump 84 compresses air and inputs it into the ink pipe 23 through the air inlet pipe 81. The high-speed airflow blows the colored ink in the ink pipe 23 into the air outlet pipe 82, and then into the waste ink collection bin 85 for centralized collection, thus achieving the purpose of cleaning the ink pipe 23. Each waste ink collection bin 85 is provided with a discharge port 11 at the bottom. An end cap 12 is detachably connected to the discharge port 11. By opening the end cap 12, the discharge port 11 can be connected to the recycling equipment through a pipe for easy processing of the waste ink in the waste ink collection bin 85.

[0035] Specifically, the second solenoid valve 26 is located near the inlet end of the ink pipe 23; the third solenoid valve 83 is located on the outlet side of the second solenoid valve 26 and is located near the ink pipe 23; and the air pump 84 is located away from the ink pipe 23.

[0036] In summary, the online intelligent identification system 100 for optical fiber production of this utility model is deeply integrated with the optical fiber drawing and preparation process. It can generate information such as color rings of different colors and serial numbers on optical fibers, expand the application scenarios of optical fibers, realize efficient, traceable and personalized optical fiber production management, and fill the industry gap.
