Title:
GALVANOMETER-BASED LASER HIGH-SPEED SCANNING AND WELDING SYSTEM FOR BATTERY BOX AND OPERATION METHOD
Document Type and Number:
WIPO Patent Application WO/2019/095269
Kind Code:
A1
Abstract:
A galvanometer-based laser high-speed scanning and welding system for a battery box, comprising: a frame (1) and a laser welding protective compartment (2); a transportation line (3) for transportation of a workpiece is provided on the frame (1), the laser welding protective compartment (2) is provided on the transportation line (3); grouped clamps (4) and a special galvanometer-based long-range laser welding machine (5) are provided in the laser welding protective compartment (2), a conveying mechanism (6) for conveying a workpiece is provided on the transportation line (3), the grouped clamps (4) are provided on the conveying mechanism (6), the special long-range laser welding machine (5) is provided on the top of the laser welding protective compartment (2); and the transportation line (3), the grouped clamps (4), the special long-range laser welding machine (5), and a tray (61) and an accompanying clamp (62) are all connected to a control center. Said system scans and welds a battery box using a special long-range laser welding machine (5), enables an efficient and stable laser welding process by means of rapid rotation of a galvanometer, and makes it possible to set a light spot movement trajectory to perform waveform control, thereby achieving an ideal welding effect. Said system has a fast welding speed and small thermal deformation, improving the production efficiency and effectively improving the welding accuracy and welding quality.
