Welding robot is an industrial robot engaged in welding (including cutting and spraying), which mainly includes two parts: robot and welding equipment. The manipulator consists of a robot body and a control cabinet. The welding equipment, taking arc welding and spot welding as an example, is composed of welding power supply, wire feeding machine, welding gun and so on. For intelligent robots, there should also be sensing systems, such as laser or camera sensors and their control devices.
Welding robots produced in the world are basically joint robots, and most of them have 6 axes. Welding manipulator can be used to improve the labor intensity of workers, can work in harmful environments, and reduce the requirements for workers' operation technology, shorten the preparation cycle of product transformation, reduce the corresponding equipment investment, improve the image of enterprise innovation and labor productivity and reduce production costs.
As of 2000, the total number of industrial robots in the world is 757,000, of which 45% are welding robots, since the rapid development of domestic industrial robots after 2000, China's mechanical arm slowly based on the world, for the development of welding robots and production applications are also more and more. At present, it is mainly concentrated in several major industries such as automobiles, motorcycles, construction machinery, and railway machinery, among which automobile production is the largest user.
When welding robot is applied, the integration of robot technology, welding technology and system engineering technology, whether welding robot can be applied in actual production and play its superior characteristics depends on the integration degree of Chinese engineers on the above technology. As the largest user of welding manipulator, it is expected that the next 10 years, China's annual output of automobiles to reach 10 million, the current welding equipment that is far from meeting the production demand, the demand for welding equipment will increase significantly, welding production line requirements more automated and flexible, to apply to a variety of small batch production requirements, robots will be used in a large number of welding production line. For China's robot manufacturers, how to seize the opportunity is an important issue to be solved, on the other hand, it also determines the fate of domestic welding robot arms.
With China's accession to the WTO after the international competition more and more intense, the demand for industrial robots will be greater, China's welding machine robot industry will face new development opportunities and challenges from abroad, our industrial robot manufacturers to seize this opportunity, to meet the challenge, for our country among the robot power and struggle.
