[Abstract]:Since the birth of industrial robot, its development has gone through a long process. In recent years, with the rapid development of computing technology, industrial robot technology and its application scope have been a great breakthrough, such as in the field of aerospace, food and chemical industry. The use of welding robots in automobile manufacturing and other fields is also increasing. At present, the automobile seat parts industry is introducing robot technology directly to the production process of automobile seat frame welding. The application of welding robot in automobile seat production is becoming more and more important. In this paper, the key technology, basic technology and teaching method of welding robot, which is widely used in the welding production of automobile seat skeleton component, are studied in detail. Firstly, the research status of this subject at home and abroad is analyzed, including welding technology, welding robot, automobile seat frame welding technology and so on. Secondly, the principle of welding technology and the basic technology of automobile seat frame welding are expounded, and the basic structure, control principle and information exchange technology of industrial robot are discussed. The general process and basic process of automobile seat firmware welding are analyzed. Thirdly, the welding method, the welding technology index, the structure of the welding robot and the application of the automobile seat frame welding robot are deeply studied. Thirdly, the welding technology of automobile seat skeleton robot is analyzed, including welding robot workstation, welding robot mechanical structure and OTC welding robot teaching method. Finally, through the analysis of the specific application cases of welding robot in the production of automobile seat skeleton, the composition, construction, working principle, working characteristics and teaching method of the welding robot workstation are studied. Taking the welding case of automobile seat skeleton robot as an example, the development, debugging, welding processing technology and teaching method of special welding tools are analyzed and studied. The application of welding robot technology and CO2 gas shielded arc welding in the production of automobile seat frame greatly reduces the labor intensity of workers and the adverse effects of welding exhaust gas on workers' health. It is of great theoretical and practical significance to improve the overall quality of the parts in batch production, reduce the production cost and improve the production efficiency of enterprises. The main purpose of this research is to find out the advantages of welding robot in industrial production by analyzing the concrete application of existing welding robot in automobile seat skeleton production, and to study the teaching method of welding robot. The common faults of welding robot are found in the process of production. By optimizing the parameters to reach the goal of optimizing the motion path and improving the production efficiency, this paper provides a powerful reference for the subsequent production and processing.
