Robot visual simulation technology is to carry out production feasibility analysis in the virtual environment of computer. Before production, through 3D modeling and simulation of a virtual environment consistent with reality, a variety of hypothetical scenario analysis and testing are carried out on potential problems to reduce the risk of real machine commissioning, and the best manufacturing process is selected from all possible candidate solutions through the simulation of the production process.

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.

Intelligent welding refers to the self-adaptive welding of products based on the welding process expert system and combining various welding sensing, automation and robot technologies. It achieves intelligent control of welding process through artificial intelligence technology and sensing technology, which greatly improves the stability of welding quality and the process reliability, and also lowers the cost.

Technically, intelligent assembly means "error-free intelligent assembly", which is realized by applying intelligent technologies to "assembly". Digital assembly tools are used. Tightening tools at the underlying execution layer are connected to the industrial Internet. Through the data acquisition and monitoring control system, parameter assignment and data collection are performed in assembly. After that, big data processing of the data collected is carried out to achieve higher efficiency and better quality.

The intelligent vision system can be used for model and derivative inspection, automatic gluing quality inspection, automatic grabbing of random incoming workpieces, and quality inspection, etc., so as to realize intelligent flexible production. Through dedicated efforts and proven technologies, RAIVAS vision technology will be used in more industries in the future to truly replace "human" with "robot". At present, it has already been widely used in automobile welding, 3C automation, elevator and special equipment.

The robot trimming system developed is an integration of trimming tools, inner panel positioning mold, moulding device, and vacuum plate system, and is used for edge rolling of vehicle doors and covers in various forms and at various positions. The vacuum plate system positions the outer panel securely, which greatly improves the stability of outer panels during trimming. It is highly adaptive to various workpiece geometries. Compared with current technologies, it requires no other device for outer panel positioning. In addition, it eliminates the setting error caused by multiple clamping during workpiece handling, reduces the logical waiting time of the robot and the outer panel positioning mechanism, and improves the work efficiency and trimming quality. The system will supervise the machining process automatically and apply adaptive control accordingly. It features sound flexibility, good process effect, short working takt, and compactness in space.

This technology integrates servo motion control, bus valve terminal, intelligent identification, RFID, sensing and other units. It serves for digital production by constructing one-stop operation platforms and creating systematic control solutions with host control system, PLC, distributed remote I/O processing, PC remote control, integrated modularization of drive and control, multi-station synchronous monitoring and other technologies.
