YAG multi-beam light splitting gradual-change type light path negative feedback control system

Abstract

The invention discloses a YAG multi-beam light splitting gradual-change type light path negative feedback control system. The system comprises a laser device, at least one coupling light path assembly, a quartz reflecting mirror and a control device; each coupling light path assembly comprises a gradual-change type light splitting device, a first energy negative feedback device and a laser coupler; the quartz reflecting mirror is arranged at an angle of 45 degrees with light beams of the laser device, each gradual-change type light splitting device is arranged at an angle of 45 degrees with refraction light beams of the quartz reflecting mirror, the refraction light beams of the first energy negative feedback devices, the refraction light beams of the laser couplers and the refraction light beams of the gradual-change type light splitting devices are located on a straight line, and the first energy negative feedback devices are located between the laser couplers and the gradual-changetype light splitting devices; and the first energy negative feedback devices and the gradual-change type light splitting devices are connected to the control device. According to the technical scheme,the multi-path simultaneous welding stability of a precision device is guaranteed, and the requirements of diversified laser welding technologies in multiple occasions are met; and meanwhile, the manufacture and maintenance costs are low, the use is simple, and the debug is rapid and convenient.

Description

technical field [0001] The invention relates to the technical field of laser processing, in particular to a YAG multi-beam light splitting gradual change type optical path negative feedback control system. Background technique [0002] Nowadays, the country strongly supports technological innovation, the social economy is developing rapidly, and the network has become an indispensable part of people's lives. Coupled with people's demand for communication, mobile communication technology has developed rapidly, and 5G communication is the future broadband mobile Because of its unique advantages, communication technology has increasingly attracted the attention and recognition of governments and relevant departments around the world. Moreover, 5G requires huge hardware equipment coverage, which is a very large cost for operators, so for a long time, 5G and optical fiber will complement each other, BOSA, active devices, passive devices, and optical fiber as It is an important h...
