China is the country that needs robots the most and the least. China has a large population, abundant and cheap labor resources, from this perspective, it is better to hire a person to use an expensive and cumbersome robot. However, if China wants to become a world power, it must do more with the least resources. Our enterprises must adopt high-tech as much as possible to produce more efficiently and win with high competitiveness, which requires a lot of robots. Humans do not have the precision, accuracy and efficiency of robots. People may lose their jobs, but more jobs will be created and the benefits to society will be greater. I believe that in the near future, the robot industry will become the economic pillar industry of the country like the automobile, the United States is a "country on the car", China can become a "country standing on the shoulder of the robot".

Current status of welding robot technology and development trend at home and abroad

The development of foreign robot field in recent years has the following trends:

1. The performance of industrial robots continues to improve (high speed, high precision, high reliability, easy operation and maintenance), while the price of a single machine continues to decline, the average price of a single machine fell from $103,000 in 1991 to $65,000 in 1997.

2. Mechanical structure to modular, reconfigurable development. For example, the servo motor, reducer and detection system in the joint module are trinity; The robot machine is constructed by the joint module and the connecting rod module. Modular assembly robot products have been marketed abroad.

3. The industrial robot control system is developing in the direction of PC-based open controller, which is convenient for standardization and networking; The device integration is improved, the control cabinet is becoming smaller and adopts modular structure; The reliability, ease of operation and maintainability of the system are greatly improved.

4. Sensors in robots play an increasingly important role. In addition to traditional position, speed, acceleration and other sensors, assembly and welding robots also use sensors such as vision and force perception, while remote control robots use multi-sensor fusion technology such as vision, sound, force and touch to conduct environmental modeling and decision control. Multi-sensor fusion configuration technology has been applied in production systems.

5. The role of virtual reality technology in robots has been developed from simulation and rehearsal to process control, such as enabling remote robot operators to create the feeling of being in a remote working environment to manipulate the robot.

China's industrial robots began to start from the "Seventh Five-Year Plan" science and technology research in the 1980s. With the support of the state, through the "Seventh Five-Year Plan" and "Eighth Five-Year Plan" science and technology research, we have basically mastered the design and manufacturing technology of robot manipulator, control system hardware and software design technology, kinematics and trajectory planning technology, and produced some key components of robots. Developed spraying, arc welding, spot welding, assembly, handling and other robots; Among them, more than 130 sets of painting robots have been applied in nearly 30 automatic painting production lines (stations) of more than 20 enterprises, and arc welding robots have been applied in the welding lines of automobile manufacturers. But generally speaking, China's industrial robot technology and the level of engineering application and foreign countries are still a certain distance, such as: reliability is lower than foreign products; Robot application engineering started late, the application field is narrow, and the technology of production line system lags behind that of foreign countries. In terms of application scale, China has installed about 200 domestic industrial robots, accounting for about four thousandths of the number of installed units in the world. The above reasons are mainly not the formation of the robot industry, the current robot production in China is in accordance with the requirements of users, "a customer, a redesign", variety specifications, small batch, low degree of universality of parts, long supply cycle, cost is not low, and quality, reliability is unstable. Therefore, it is urgent to solve the key technologies in the early stage of industrialization, carry out comprehensive planning of products, do a good job of serialization, generalization and modeling design, and actively promote the industrialization process.

Robot technology is an important part of high technology, and its industrialization process has just started in our country, although it has made certain achievements, there are still many difficulties and deficiencies, so it needs more care and support from many aspects.

National policy support is an important prerequisite for accelerating the industrialization of high and new technology. According to the relevant departments of the Chinese government should organize forces to carry out adequate investigation and research, on this basis, formulate practical and feasible promotion and application of robots and promote robot research and development of inclined policies. For example, supporting policies for the robot industry in terms of taxation, investment and loans. The Japanese government has adopted a series of measures to encourage enterprises to apply robots through the formulation of policies, and the experience of Japanese robots in opening up the domestic market is worth our reference. In addition, for robot users, you can consider giving certain financial subsidies to encourage purchases. In order to avoid industrial accidents and occupational diseases caused by dangerous and harsh working environment, and protect the physical and mental safety of workers, industrial robots are forced to be used instead of some special jobs, such as spraying and casting, through labor laws. This can greatly increase the number of industrial robots in demand.

The industrialization of robot in our country must be driven by the market. As a high-tech robot, its development is closely related to social production and economic conditions. The research and development of robots is only based on the principle of technical realization of the possibility to select the priority application of robots, and take this as a breakthrough, and it is important to penetrate and spread to other fields.
