This paper mainly analyzes the main problems of the role and application of robots in the body welding production line. Through the analysis of the application of industrial robots at home and abroad, it is known that industrial robots play an important role in the development of the automotive industry, especially in the body welding production; currently there are still many problems in the application of robots in body welding production. Industrial robots are expected to play an increasingly prominent role in the automotive industry, and problems in applications will be gradually solved.
1 Introduction
According to the statistics of the China Association of Automobile Manufacturers, since 2000, the average annual growth rate of China's automobile production and sales has exceeded 20%, far higher than the global average growth rate; and the annual production volume accounts for the proportion of global automobile production continues to rise. The production and sales volume exceeds that of the United States, becoming the number one country in the global automotive industry. According to forecasts, China's automobile consumption market will continue to grow at a relatively fast rate.
The growth of the automotive market puts higher demands on automobile production technology, and the industrial robots have been widely applied in the automobile manufacturing industry. According to statistics, more than half of the industrial robots produced by domestic manufacturers in recent years are provided to the automotive industry. At present, the international application of industrial robot technology in the manufacturing industry has been extensive, and has now been extended from traditional manufacturing to other manufacturing industries. However, the automotive industry is still the main application area for industrial robots. It is understood that 60% of industrial robots in the United States are used in automobile production. Industrial robots used in the automotive industry worldwide have reached 37% of total consumption, and industrial robots for automotive parts account for about 24%.
The use of industrial robot technology in the production of automobile industry not only saves manpower, reduces costs, improves equipment utilization, improves product quality and output, but more importantly, it can protect workers' safety, improve working conditions, reduce labor intensity and reduce personnel risks. ,Improve work efficiency.
2The role of robots in the body welding production line
Industrial robots are widely used in the four major production processes of stamping, welding, painting and final assembly in automobile production. The specific applications in the automotive body welding production line are: spot welding, arc welding, handling, assembly, Detection, etc. Industrial robots have become the main automation tool for flexible manufacturing systems and computer integrated manufacturing systems. In developed countries, complete sets of industrial robot automated production lines have become the mainstream and future development direction of automation equipment.
