Abstract
Description
Technical Field
[0001] This utility model relates to the field of polishing robot technology, specifically a polishing robot polishing module. Background Technology
[0002] When producing wind turbine blades, one half is produced first, and then the two halves are joined together and bonded to form a complete wind turbine blade. The surface quality of the wind turbine blade determines its service life. After the grouting is completed, some misalignment defects will appear on the outer and inner surfaces of the blade, which need to be polished and repaired.
[0003] Currently, when polishing wind turbine blades, manual hand-held polishing machines are required to polish the surface of the blades. During the polishing process, the polishing machine needs to be pressed down. Manual operation cannot control the downward pressure provided during operation, which leads to a reduction in polishing quality. To address this, we propose a polishing robot module.
