Novel modular dust-proof and damp-proof high-efficiency high-power optical fiber winding plate structure

Abstract

The invention discloses a novel modular dust-proof and damp-proof high-efficiency high-power optical fiber winding plate structure, which comprises an optical fiber winding plate, wherein the optical fiber winding plate is provided with a first surface and a second surface; the first surface is provided with a circle light surface area and a wavy notch groove area; the wavy notch groove area surrounds the periphery of the circle light surface area; the optical fiber winding plate is provided with an incident optical fiber opening and an emergent optical fiber hole; the emergent optical fiber hole penetrates through the first surface to the second surface; an optical fiber from an outlet end of a pump light source enters the wavy notch groove area through the incident optical fiber opening, is wound into notch grooves in the wavy grooving area from outside to inside in a manner that the perimeters are gradually reduced, enters the circle light surface area from an appropriate position, adjacent to the circle light surface area, of the wavy grooving area and is wound in the circle light surface area from outside to inside in a manner that the perimeters are gradually reduced; and an emergent optical fiber at the tail end of the optical fiber passes through the emergent optical fiber hole to the second surface and then is connected with an external optical device. The novel modular dust-proof and damp-proof high-efficiency high-power optical fiber winding plate structure has the advantages of being modular, compact in structure and easy to install and repair.

Description

technical field [0001] The invention relates to the technical field of fiber lasers, in particular to a novel modular dust-proof, moisture-proof, high-efficiency and high-power optical fiber winding structure. Background technique [0002] High-power continuous wave fiber lasers are mainly used in various metal sheet metal processing, including cutting, welding, surface coating and other industrial applications. The focus spot size and output power of the output laser determine the energy density of the processing surface, which directly affects the effect of metal sheet metal processing. The smaller the focus spot, the more precise the processing quality can be provided, and the higher the output power, the faster the processing speed can be provided, and the thicker metal sheet can be processed. [0003] With the popularity of fiber lasers in various industrial applications, the requirements for output beam quality and output power of single-mode fiber lasers are also inc...

AI Technical Summary

Problems solved by technology

[0006] 2. Single design structure

[0007] 3. Incomplete heat dissipation

This design may overheat the exit fiber as it cannot contact the reel

[0008] 4. Difficult maintenance

This one-piece design makes later maintenance very difficult

Once the gain fiber is burned, it is difficult to strip it from the water cooling plate without affecting other components

[0009] 5. Lack of sealing considerations

Therefore, the working performance is greatly affected by the humidity and temperature of the environment, and it is also easy to cause dust accumulation
