With the need of production industry, laser processing robot appears, which is an international advanced manufacturing technology facing the 21st century. Almost at the same time as the laser was born, in 1962, the United States union company also launched the first industrial robot.

Since 1970s, with the continuous improvement and development of CO2 laser and numerical control technology, laser technology has become an advanced processing method for plate cutting in industry. Cutting robots are often used in industrial production. According to different functions and working principles of robots, cutting robots are divided into flame cutting robots, plasma cutting robots, laser cutting robots and water cutting robots. Among many cutting robots, the laser cutting robot has the highest efficiency and the cutting accuracy is incomparable to other cutting robots.

Since then, metal laser cutter has gone through a series of development processes. Until the 1990s, the tide of global informatization came, computer technology, microelectronics technology, network technology and advanced manufacturing technology were rapidly upgraded, and industrial robot technology also developed rapidly. It has the characteristics of repetitive and accurate production, and meets the requirements of large-scale batch production in the manufacturing industry. Assembly on the production line replaces manual operation, which can not only relieve the complicated labor of workers, but also improve the production quality. At present, industrial robot technology is becoming more and more mature, and has become a standard equipment and widely used in industry.

The working principle of the laser cutting robot is to focus the laser beam emitted from the laser into a high power density laser beam through the optical path system. The laser beam irradiates the surface of the workpiece to make the workpiece reach the melting point or boiling point. At the same time, the high-pressure gas coaxial with the beam blows away the molten or vaporized metal, and makes the laser beam and the material move relatively along a certain track, thereby forming a certain shape of slit. The cutting robot replaces the traditional mechanical knife with an invisible beam. It has the characteristics of high precision, fast cutting, not limited to the cutting pattern, automatic typesetting, saving materials, smooth cutting, and low processing cost. It will gradually improve or replace the traditional metal cutting process equipment.

The mechanical part of the laser cutter head has no contact with the workpiece, and will not scratch the surface of the workpiece during work; The cutting robot is fast, the incision is smooth and flat, and generally no subsequent processing is required; The cutting heat affected zone is small, the plate deformation is small, and the cutting seam is narrow (0.1mm ~ 0.3mm); The notch is free of mechanical stress and shear burr; High processing accuracy, good repeatability, and no damage to the material surface; CNC programming, can process any plan, and can also cut the whole board with a large format, without opening the mold, which is economical and time-saving. Metal laser cutter is widely used in the processing of metal and non-metal materials, which can greatly reduce the processing time, reduce the processing cost and improve the workpiece quality. In contrast, the traditional cutting technology process is relatively complex, which requires not only early drawing and measurement preparation, but also polishing of the edge after cutting. Metal laser cutting machine cuts the workpiece quickly and neatly, saving a lot of cumbersome processes, which is popular in the manufacturing industry.

In recent years, the rapid development of laser technology and the continuous progress of intelligent, automation and information technology in the field of advanced manufacturing have promoted the combination of robot technology and laser technology. Industrial robots combine with laser technology to form a new industrial processing process, which can not only improve the yield and reduce errors, but also operate continuously for 24 hours, shorten the production cycle, expand production capacity, and play a role in reducing costs and improving efficiency for enterprises. Major manufacturers have also developed intelligent laser cutting robots, intelligent welding robots, intelligent grasping robots, intelligent cleaning robots and intelligent grinding robots with multiple functions of automatic tracking and automatic adjustment, which are widely used.

In terms of industrial application, the expanding development demand of the automobile industry has driven the application and development of laser cutting robots in automobile parts processing. Laser cutting robot has high positioning accuracy and large processing range; Six axis linkage can realize the cutting of large-scale three-dimensional parts, automatic identification of workpiece fixture models, and automatic loading and unloading of two stations. It has the characteristics of accurate cutting, convenient and safe operation, and improved production efficiency. By using the laser cutting robot, the formed parent product can be cut into different 3-5 sub products, thus reducing the number of mold development, reducing production costs, and not delaying operation efficiency. In addition, during the epidemic period, the use of laser cutting robots can greatly reduce the use of manual labor and help the rapid resumption of work and production. Moreover, the robot is flexible, flexible, fast in laser cutting speed, high in precision and good in quality. It can handle complex cutting needs, realize scientific and technological empowerment, and bring huge economic benefits to enterprises.

In short, laser cutting robots have prominent advantages in the field of automobile manufacturing, which meet the needs of the automobile industry to reduce costs, conform to the development trend of improving quality, and play a greater role in improving the manufacturing quality and level of automobiles. The application of robot cutting is the inevitable trend of modern manufacturing industrial cutting. A single spark can start a prairie fire. This song of light and fire will surely play in the modern industrial era!
