针对汽车板激光拼焊工艺特点,研制了激光自动焊接系统,此系统由激光器、焊接机床和控制系统组成,采用IPG5000光纤激光器作为光源,机械人上、下料,切割-焊接组合技术,柔性电磁铁定位、夹紧,西门子840D数控系统。解决了汽车板装夹、定位,曲线、折线焊缝拼接、自动控制系统等关键技术。结果表明:此焊接系统光束质量好,性能稳定、可靠;可以焊接板厚0.5～3 mm,长度小于2 000 mm的直线、曲线、折线汽车板,汽车拼焊板的焊接精度高,焊缝质量好,达到ISO18001标准。
Aiming at the characteristics of automotive welding plate welding process, an automatic laser welding system was developed. The system consists of a laser, a welding machine and a control system. The system uses an IPG5000 fiber laser as a light source, a combination of robotic loading and unloading, cutting and welding, Iron positioning, clamping, Siemens 840D CNC system. Solve the car plate clamping, positioning, curves, broken line weld splicing, automatic control systems and other key technologies. The results show that this welding system has good beam quality, stable and reliable performance, and can weld straight, curved and broken car plates with plate thickness 0.5-3 mm and length less than 2000 mm. The welding quality of the welding plate is high, Well, up to ISO18001 standard.
