Description

Technical Field

[0001] The invention relates to the technical field of optical fiber coupling, in particular to a semiconductor laser lens coupling device and a lens angle adjustment system. Background Art

[0002] Fiber coupling refers to the process of transmitting an optical signal from an optical device (such as a laser, light-emitting diode) into an optical fiber. This process is critical to fiber-optic communication systems and many fiber-optic applications. Optical fibers have extremely low transmission losses and can transmit optical signals over long distances without distortion or attenuation. Coupling ensures that light can effectively enter the optical fiber and achieve long-distance transmission. Light transmission inside the optical fiber is carried out through a specific mode. The coupling process ensures that the light mode output by the transmitter matches the mode supported by the optical fiber, thereby reducing mode dispersion and improving transmission efficiency. Fiber coupling can maximize the output power of a laser or other light source and improve the energy efficiency and performance of the system. Optical fibers have good flexibility and small size, making system design more flexible and compact. Coupling technology allows the light source to be precisely connected to the optical fiber, which is easy to integrate into various devices. Optical fibers provide electrical isolation, which is very important for certain applications that need to avoid electromagnetic interference. The coupling process ensures that the optical signal is transmitted safely and is not affected by external electromagnetic interference. In fiber-optic communications, multiple wavelengths of light can be transmitted simultaneously in the same optical fiber (wavelength division multiplexing, WDM). Coupling technology ensures that different wavelengths of light can effectively enter the optical fiber. Fiber-optic systems are easy to upgrade and maintain. Coupling technology allows the replacement or upgrade of light sources and optical fibers without interrupting service. Optical fibers are insensitive to environmental changes (such as temperature and humidity), and coupling technology ensures that optical signals can be stably transmitted in various environments. Fiber optic transmission avoids the risk of radiation and laser exposure, and coupling technology ensures that the light beam is safely guided into the optical fiber, reducing potential hazards to operators and the environment. The installation and maintenance costs of fiber optic systems are relatively low, and the development of coupling technology helps to reduce the cost of the entire system.

[0043] Working principle: When the lens body 5 is not needed, the lead screw 203 is driven to rotate by the motor 202. Due to the meshing connection between the lead screw 203 and the moving block 204, the lens body 5, the connecting shaft 304 and the square plate 305 on the moving block 204 are moved toward the direction of the optical fiber placement seat 9;

[0044] At this time, since the moving block 204 is provided with a rack 602, and the rack 602 is meshed with the gear 604, the rotating shaft 603 is driven to rotate. Since the rotating shaft 603 and the connecting column 606 are connected by the pulley 605 and the conveying belt 607, the connecting column 606 is driven to rotate. Since the connecting column 606 is provided with a first support plate 701, the rubber plate 707 and the protective cover 708 are driven to rotate along the outer side of the connecting column 606, so that the moving column 703 at the bottom of the second support plate 704 moves in the arc-shaped slide groove 702, thereby driving the rubber plate 707 and the protective cover 708 to rotate to one side of the moving seat 201, and the rubber plate 707 and the protective cover 708 are located above the moving seat 201 and the motor 202.

As the moving block 204 moves, the push plate 302 is used to push the square plate 305 to rotate, driving the lens body 5 to rotate downward. At this time, the top of the lens body 5 contacts the top of the rubber plate 707, pressing the rubber plate 707 downward, and covering the outer side of the lens body 5 with the protective cover 708, so as to protect the lens body 5 conveniently and avoid the lens body 5 being scratched by foreign objects, thereby playing a role of further protection.
