Galvanometer welding system adopting coaxial visual positioning function

Abstract

The invention discloses a galvanometer welding system adopting a coaxial visual positioning function. The galvanometer welding system involves a 45-degree reflector base, the top end of the 45-degree reflector base is connected with an optical fiber laser inlet end through a closed connecting pipeline, one side of the 45-degree reflector base is connected with a closed transmission light channel, the tail end of the closed transmission light channel is connected with a scanning galvanometer, an output end of the bottom of the scanning galvanometer is connected to a 45-degree light-transmitting lens base through a galvanometer transmission light channel, a reflecting light outlet end is arranged on one side of the 45-degree light-transmitting lens base, the bottom end of the 45-degree light-transmitting lens base is provided with a transmission light outlet end, a frame type light supplementing lamp is arranged at the bottom end of the 45-degree light-transmitting lens base, and an industrial camera is arranged on one side of the 45-degree light-transmitting lens base. The system has very strong time advantages on array type and intensive welding spot processing. Compared with traditional welding, the galvanometer welding system adopting vision capturing is matched with professional graphic processing software, and thus instant multi-point welding based on program control is realized.

Description

technical field [0001] The invention belongs to the technical field of vibrating mirror welding, and in particular relates to a vibrating mirror welding system adopting coaxial vision positioning. Background technique [0002] Laser welding is to radiate a laser beam with high energy density to the metal surface. Under the interaction between the laser and the metal, the metal absorbs the laser energy and converts it into heat energy. After the metal melts, it cools and crystallizes to form a weld. Lithium battery laser welding system is mainly composed of fiber laser, laser welding head, automatic focus adjustment system, visual positioning system, five-axis linkage workbench, CCD monitoring system and purification and ventilation system. Compared with traditional welding methods, laser welding has the following advantages: 1. Laser beam focus diameter is less than 0.5mm, power density is higher than 105-107W / cm2, heat-affected zone is small, workpiece deformation after wel...
