【Abstract】 The development of a new production line for ro- botization and prompting efficiency of lithiumion battery sort- ing process is presented by using multiple high speed light weight parallel manipulators. The open architecture of hardware and software of the numerical control system is essentially de- veloped based on a distributed control system (DCS) built by using the PXI platform and two multi-axis motion controllers, and also a sorting strategy is developed to achieve the task equilibrium and the shortest movement space. Otherwise, some crucial motion control techniques such as high speed data buff- ering, high speed data synchronization using notifiers and high speed breakpoints capture and output, etc, are investigated and applied to this system to improve the sorting efficiency of a single machine and the cooperation ability of multi-machine. This system is tested and controlled by integrating techniques based on database communications, which shows the validity of the proposed scheme for network control of multi-robot. This system is designed in such a way that enables high information integration, high sorting efficiency, high reliability and is suc- cessfully used in battery sorting, it is the first successful appli- cation of parallel manipulator for rapid and automatic sorting of batteries in China.更多还原
