BIW Assembly Technology
The flexible high-speed intelligent BIW assembly uses technologies such as vision guidance, servo positioning, flexible passive trolley, intelligent vehicle model switching device, flexible trimming, and off-line commissioning to achieve flexible high-speed intelligent production of BIW. At present, this technology has been successfully applied to a joint-venture brand production line and an independent brand production line, realizing unmanned whole line production for the first time and supporting production of 5 models on the same line with intelligent seamless switching. It enables an annual output of 240,000 vehicles (45 seconds/vehicle). From preliminary planning to design and development, manufacturing, system integration and commissioning, the technology is developed independently, reaching the domestic leading in terms of production line efficiency, automation, digitalization, intelligent flexibility and application of advanced technologies.
