Analysis of the Development Status of Welding Industry Robots in China

China's industrial robots started from the "Seventh Five Year Plan" scientific and technological research in the 1980s. With the support of the state, through the "Seventh Five Year Plan" and "Eighth Five Year Plan" scientific and technological research, we have basically mastered the design and manufacturing technology of robot operating machines, hardware and software design technology of control systems, kinematics and trajectory planning technology, produced some key components of robots, and developed robots for painting, arc welding, spot welding, assembly, and handling; Among them, more than 130 sets of spray painting robots have been widely applied in nearly 30 automatic spray painting production lines (stations) of more than 20 enterprises, and arc welding robots have been applied in welding assembly lines of automobile manufacturing plants. However, overall, there is still a certain gap between China's industrial robot technology and its engineering application level and that of foreign countries, such as lower reliability than foreign products; Robot application engineering started relatively late, with narrow application fields and a gap in production line system technology compared to foreign countries; In terms of application scale, China has installed about 200 domestically produced industrial robots, accounting for approximately 0.04% of the global installed number. The above reasons are mainly due to the lack of a robot industry. Currently, robot production in China is based on user requirements, with a "one customer, one redesign" approach. There are many varieties and specifications, small batch sizes, low degree of component universality, long supply cycles, high costs, and unstable quality and reliability. Therefore, it is urgent to address the key technologies in the early stages of industrialization, comprehensively plan products, do a good job in series, universal, and modular design, and actively promote the industrialization process.

Industrial robot technology is an important component of high technology, and its industrialization process has just begun in China. Although certain achievements have been made, there are still many difficulties and shortcomings, so it requires more attention and support from various aspects.

National policy support is an important prerequisite for accelerating the industrialization of high-tech industries. According to the relevant departments of the Chinese government, efforts should be organized to conduct sufficient investigation and research. Based on this, practical and feasible policies should be formulated to promote and apply robots, as well as to facilitate robot research and development. Implementing supportive policies for the robotics industry in terms of taxation, investment, and loans. The Japanese government has formulated policies and taken a series of measures to encourage enterprises to apply robots, and the experience of expanding the market for Japanese robots in China is worth learning from. In addition, for robot users, it is possible to consider providing certain financial subsidies to encourage purchases. In order to avoid work-related accidents and occupational diseases caused by dangerous and harsh working environments, and to protect the physical and mental safety of workers, some special occupations such as spraying and casting can be replaced by industrial robots through labor laws. This can greatly increase the demand for industrial robots.

The industrialization of industrial robots in our country must be driven by the market. As a high-tech, the development of robots is closely related to the production and economic conditions of society. The research and development of robots should prioritize the application areas based on the principle of high technological feasibility, and use this as a breakthrough point to penetrate and spread to other fields.
