面向多尺度/跨尺度微型零件全自动微装配的微装配空间数字化技术基础及应用研究

The high resolution and the small field of view (FOV) and depth of field (DOF) of the microscopic visual systems in micromanipulation/microassembly systems result in the technical barriers to microassembling the multiscale and trans-scale micro parts, and restrict the realization of the full automatic microassembly based on the microscopic visual servoing control method. Aiming at these problems, and inspired by the requirements of microassembling the ICF micro-targets, in this project, we propose the concept of the computed microscopic visual tomography (CMVT) and the concept of digitizing the microassembly space based on the CMVT and the reconstruction method of the micro-parts based on its CAD model. Both the principle and method of the CMVT and the technology and method of digitizing the microassembly space will be thoroughly researched. Based on digitizing the micromanipulation/microassembly space, the expanding method of the FOV and FOV of the microscopic visual systems based on the digital information of the microassembly space, the in-line observing and precision measuring methods of the position and orientation of the multiscale/trans-scale micro parts, the end-effectors of the micromanipulators, and mictorobots for micromanipulation/microassembly, the path planning methods and the decoupling control methods of the microassembly, and the full automatic microassembly of the multiscale/trans-scale micro parts, will be thoroughly studied. Through this project, the theoretical fundamentals for realizing the full automatic micromanipulation/microassembly of the multiscale/trans-scale micro parts and developing corresponding instruments will be established.
