In order to meet the diverse needs of customers for products, construction machinery is gradually developing towards the "New Special" small batch, which also accelerates the intelligent and automated development of welding robots. In recent years, the research and application of welding robot technology have achieved many outstanding results in weld seam tracking, information sensing, offline programming and path planning, intelligent control, power supply technology, simulation technology, welding process methods, and remote control welding technology. From the perspective of the development trend of robot technology, welding robots, like other industrial robots, are constantly developing towards intelligence and diversification. Specifically, it is manifested in the following aspects:
(1). Intelligentization applies intelligent control technologies such as laser, vision, sensing, detection, image processing, and computer to welding automation equipment, enabling it to automatically adjust and optimize welding trajectory and process parameters according to the actual situation of welding under various complex and changing welding conditions, achieving high-quality and efficient welding intelligent control and automatic seam tracking, Greatly improving the robot's operational performance and adaptability to the environment.
(2). Due to the rapid development of microelectronics technology and the application of large-scale integrated circuits, the reliability of welding robot systems has been greatly improved. The performance of welding robots continues to improve (high speed, high precision, high reliability, easy operation and maintenance), while the price of single machines continues to decline. In the past, the reliability of robot systems was usually several thousand hours, but now it has reached 50000 hours, which can meet the needs of any situation. At the same time, the integrated wiring of multiple welding robots and handling robots can achieve fully automated production, minimize human factors, and significantly improve product quality uniformity and production efficiency.
(3). Flexible modern production requires that the same equipment can meet the processing requirements of the same type and different specifications of workpieces, and even the welding automation processing of different types of workpieces. At the same time, due to the relatively high one-time investment of large welding automation equipment or production lines, it is necessary to consider flexibility as much as possible when designing such welding equipment, forming a flexible manufacturing system to fully utilize the equipment's efficiency.
(4). The development of modern network technologies such as networked intelligent interfaces and remote communication has promoted the development and application of integrated control technology for welding automation equipment. By integrating automatic control of the production process through the network, utilizing computer technology, remote communication and other technologies, welding process and quality information, production management and other information can be digitally integrated through the network, achieving offline programming, remote monitoring, diagnosis, and maintenance.
(5). Research on clean and environmentally friendly new processes, materials, and technologies to reduce the generation of welding dust. At the same time, the smoke generated during the welding process is purified through centralized treatment technology, further improving the welding environment. Welding pollution treatment equipment has evolved from being single, fixed, and large-scale to being complete, modular, mobile, miniaturized, and resource efficient. The treatment of the main polluting welding smoke and dust adopts local ventilation as the main method, supplemented by comprehensive ventilation.
