Laser is one of the four major scientific and technological inventions in the 20th century, along with computers, semiconductors and atomic energy. In the past ten years, due to the continuous development of laser technology, the application fields of lasers have also been continuously expanded, which has promoted the technological progress of related industries. At the same time,progress in intelligence, automation and information technology in the advanced manufacturing field have also promoted the integration of industrial robot technology and laser technology, especially the development needs of the automotive industry, which has promoted the formation and development of the laser processing industrial robot industry.

The robot laser processing system not only has the characteristics of flexible movement and high flexibility of industrial robots, but also has the advantages of fast processing speed, good quality, and small thermal impact of lasers, which well meets the requirements of the development of modern manufacturing, which plays a huge role in the automotive industry especially.

At present, in the automotive industry, laser welding industrial robots have become the most advanced manufacturing technology and have been widely used. For example, Volkswagen of Germany, General Motors of the United States, Toyota of Japan and other automobile assembly production lines have adopted a large number of laser welding industrial robots to replace traditional resistance spot welding equipment, which not only improves the quality and grade of products, but also reduces the weight of the car body and saves a large number ofmaterials.which enables enterprises to obtain high economic benefits.
