Abstract: With the rapid development of China's wind power generation industry, wind turbine blades, as the key core components of the whole fan, are becoming larger and lighter. With the increasing size of wind turbine blades, the difficulty of grinding operations in the production process is also increasing. At present, the blade grinding process in wind power blade manufacturing enterprises is still carried out by manually adding auxiliary climbing tooling. The whole process needs a large number of workers, and has low grinding efficiency, unstable grinding quality, high dust concentration in the working environment, and serious safety risks. In this case, the development of wind turbine blade automatic grinding robot has become the same goal of each wind turbine blade production enterprises. This paper mainly discusses a new kind of automatic grinding robot equipment for wind turbine blades. The equipment mainly includes omnidirectional AGV car, lifting platform, efficient adaptive grinding head, Kuka long arm downward type manipulator, efficient explosion-proof dust collector, integrated control unit and sensing control system, etc. In the equipment composition of wind turbine blade automatic grinding robot, omnidirectional AGV and Kuka manipulator are all standard spare parts, which are introduced here. This paper mainly describes the self-developed efficient adaptive grinding head and automatic grinding control method in detail. The application and promotion of wind turbine blade automatic grinding robot can effectively reduce the number of workers in the blade production and grinding process, enhance the grinding efficiency, stabilize the grinding quality, improve the working environment of the process, and have a positive effect on promoting the intelligent level of the blade manufacturing industry.
