Description
Technical Field
[0001] The utility model relates to the technical field of optical fiber cutting machines, in particular to an optical fiber protection mechanism for an optical fiber laser cutting machine. Background Art
[0002] With the continuous development of industrial automation and laser processing technology, fiber laser cutting machines have become an important cutting tool in modern manufacturing. Their superior cutting accuracy and efficiency have made them widely used in the processing of materials such as metals, plastics, and wood. However, during the laser cutting process, due to factors such as high temperature, laser radiation, and dust and smoke generated by cutting, the protection of optical fiber and laser equipment becomes crucial.
[0003] Traditional laser cutting equipment often lacks protective design. Typically, the fiber connectors and focusing components of fiber laser cutting machines are exposed to the cutting environment, making them susceptible to high temperatures and dust. This can lead to degradation of fiber performance and unstable laser transmission, thus compromising cutting quality. Furthermore, the smoke and dust generated during the cutting process not only reduce the cleanliness of the working environment but can also cause equipment failure and operational safety hazards.
[0004] Most of the protective measures in existing technologies are static, lacking flexibility and adaptability, and cannot effectively respond to the challenges under different cutting conditions. Many devices cannot adjust the position of the protective structure in time, resulting in direct impact on optical fibers and laser components during the cutting process. At the same time, existing airflow processing systems are often poorly designed and cannot effectively remove the exhaust gas and heat generated by cutting, thus affecting the overall cutting effect.
[0005] Therefore, it is very necessary to invent an optical fiber protection mechanism for an optical fiber laser cutting machine. Utility Model Content

[0028] Advantages of Fiber Optic Protection
[0029] 1. Prevent high temperature from affecting optical fiber:
[0030] A large amount of heat is generated during the laser cutting process, especially during high-power cutting. The temperature increase may cause damage to the optical fiber connector 4 and the focusing component 5. By using the airflow system of the protective structure 7, the temperature around the optical fiber can be effectively reduced. This design can reduce the degradation of optical fiber performance caused by high temperature and maintain the stability of laser transmission and cutting accuracy.
[0031] 2. Dust isolation and extraction:
[0032] During the cutting process, a large amount of dust and smoke will be generated. If these pollutants are deposited on the optical fiber connector 4 or the collimation component 3, they will affect the propagation quality of the laser. The high-speed airflow formed by the protective structure 7 through the air inlet pipe 73 and the air outlet pipe 74 can not only quickly extract these pollutants, but also form an effective isolation between the optical fiber and optical components and the cutting area, reducing the damage of dust to the optical fiber.
[0033] 3. Maintenance of optical fiber cleanliness:
[0034] Traditional optical fiber protection methods may not be able to completely prevent the dust and smoke generated during the cutting process from contaminating the optical fiber. The dynamic protection design of this device can be adjusted according to the actual cutting position to ensure that the optical fiber remains in a relatively clean environment, thereby improving the cleanliness of the optical fiber and extending its service life.
[0035] 4. Thermal management and safety:
[0036] In addition to protecting the optical fiber from high temperatures, the airflow design can also effectively manage the overall temperature of the cutting area, reducing the risk of equipment failure. By maintaining a suitable operating temperature for the optical fiber and its components, the probability of optical fiber failure due to overheating is reduced, ensuring the safety and reliability of the equipment.
[0037] Summarize
[0038] In summary, the fiber protection design of this device fully considers the effects of high temperatures and dust on optical fibers. Through effective thermal management and dust isolation, it not only extends the service life of the optical fiber but also ensures stability and precision during the laser cutting process. This comprehensive protection design enables the device to perform even better during laser cutting, adapting to even the most demanding industrial environments.
