Description
technical field [0001] The invention relates to a laser processing system, in particular to a laser light guide system for solving the problem of long optical path in impeller welding. Background technique [0002] The impeller welding process includes the welding of the blade and the upper cover, the blade and the lower cover, the hub and the shaft. These three processes are completed on three stations respectively. Before the present invention was made, similar three-station impeller welding systems used CO2 lasers, three sets of light guiding and focusing systems, and three sets of Z-axis workbenches. Each set of light guide focusing system is composed of 2 reflecting mirrors and a reflecting focusing mirror. The whole system requires 8 mirrors, and the length of the optical path entering the machine tool is more than 2 meters. It exposed many problems such as complex structure, many mechanical parts and optical components, high material cost, troublesome debugging, in...
