With the development of science and technology and the gradual improvement of the understanding of welding automation, the demand for high-quality products has increased rapidly, which puts forward higher requirements for welding technology. In recent years, welding robots have emerged in "smart factories", and their status in the industry cannot be separated from motion control.
After the welding robot has become a symbol of welding automation, as the industrial production system develops in a large, complex, dynamic and open direction, the traditional industrial motion control system and welding production equipment based on a single robot have been difficult to meet the diverse needs of production tasks. The multi-robot linkage system effectively improves the system load capacity and enhances application flexibility, and can quickly and efficiently complete industrial tasks that cannot be completed by a single robot, such as collaborative welding, assembly without fixtures, and collaborative handling of large and heavy workpieces.
1.LIGENT robot multi-machine linkage welding system
The LIGENT robot has conducted sufficient market research on the application environment and process requirements of the welding industry. After a long period of independent research and development, it has overcome the technical problems of multi-machine linkage motion control algorithms and launched the first domestic multi-machine linkage welding system, multi-machine linkage welding The system completely breaks the dilemma of a single robot working alone and time-consuming multi-position welding of a single workpiece. At present, it has been successfully applied in well-known domestic automobile manufacturers, and the welding effect and market feedback are excellent.
According to actual production needs, the multi-machine linkage system precisely controls the motion process of industrial robots. The multi-machine linkage scene application is actually a motion process in which a controller operates several robotic arms, which significantly improves the cost reduction and efficiency increase of the enterprise and saves hardware costs; at the same time, it can coordinate the linkage between different robotic arms and other mechanical units.

2.Technical advantages of multi-machine linkage welding system
Multi-machine linkage welding system is the first multi-machine linkage high-precision welding control system launched by LIGENT robot. The function of this system allows one control cabinet to simultaneously control 6 industrial robot bodies or positioners to complete the arc welding operation. The configuration methods are flexible and diverse. Multiple industrial robots can follow one positioner to work, or some of the multiple industrial robots can grab workpieces, act as positioners and fixtures, etc., and other industrial robots can follow and work together. After the configuration plan is determined, only a few simple steps of calibration are required to complete the calibration of the coordinate system of the positioner and robot. The subsequent point teaching work is also very simple and convenient, such as single step, reverse, jump, automatic return to the path point, online editing and modification of instructions, and rich debugging functions greatly shorten the debugging time.

3.Where do you need to improve trajectory accuracy, where are the "points"
The O-shaped trajectory planning algorithm independently developed by LIGENT robot cooperates with the multi-machine linkage synchronous trajectory planning algorithm to keep the entire welding trajectory including the smooth transition section at a constant speed, thereby ensuring the consistency of welding quality.
In order to facilitate the welding of round pipes, LIGENT robots focus on the actual application needs of the market, and are used in a large number of arc welding projects such as automobile production lines, children's toy production lines, large workpiece welding in workshops, frame welding, stainless steel bellows welding, and even small parts welding. Conduct field research work. Concentrate on research and create the unique ccir single-point arc command, which only needs one teaching point. In the application of the teaching function of continuous arc trajectory, there will no longer be complicated auxiliary points and target points, which makes people stupid. Stupid can't tell. Where it is necessary to improve trajectory accuracy, where to insert. Only need to insert a ccir command, which is faster and more flexible to improve the trajectory accuracy, more intuitive to use, quick to apply, and the path planning is more concise and efficient.
After several years of development, the LIGENT robot automation solution built by robots based on subdivided industries has achieved initial results, forming scale effects in the fields of automobile production, construction machinery, motorcycles, railway vehicles, and boilers. LIGENT Robot strives to build a world-class brand, and looks forward to more partners joining in to help my country's automation process.
