Description

Technical Field

[0001] The present invention relates to the technical field of fiber laser production, and in particular to an automatic material taking assembly for a fiber laser. Background Art

[0002] A fiber laser is a solid-state laser with a rare-earth element-doped glass fiber as the gain medium, which generates laser amplification through optical pumping. Its core structure consists of a pump source, a gain fiber, a resonant cavity, and a heat dissipation system. By utilizing the waveguide effect of the optical fiber, photons are confined to propagate within the core, and high-efficiency energy conversion is achieved through stimulated emission. Compared with traditional lasers, fiber lasers have advantages such as excellent beam quality, high electro-optical conversion efficiency, strong thermal management performance, and compact structure, and are widely used in fields such as industrial processing, medical beauty, and communication sensing. With the upgrade of intelligent manufacturing, the integration requirement of fiber lasers and automated equipment has become increasingly prominent. That is, in a laser processing system, as a key module connecting the loading and unloading processes, the automatic material taking assembly can achieve the efficient transfer of raw materials and processed parts through intelligent recognition and precise grasping technology, and jointly build an unmanned production line with the fiber laser, significantly improving the processing rhythm and equipment utilization rate.
