Abstract: Honeycomb sandwich structural panels are widely used in various satellite structures in China. In order to meet the requirements of satellite structure connection and equipment installation, each honeycomb sandwich structural plate contains more than 500 embedded parts on average, and the total assembly and allocation of embedded parts reaches one million level every year. However, in the process of satellite structural plate assembly, it still relies on manual identification of information on drawings or 3D models one by one, which leads to quality problems such as poor production efficiency, wrong assembly, missing assembly and wrong direction assembly. To solve the above problems, a smart projection aided assembly system for satellite structural plate manufacturing is proposed. By projecting the assembly position of the embedded parts on the product at one time, and clearly marking the specifications and contour features of the embedded parts, the proposed system can guide the operators to assemble. The application shows that, compared with the previous manual identification and operation methods, the proposed system is more effective, and it can greatly improve the operation efficiency and quality consistence of embedded parts assembly in the process of satellite structural plate manufacturing.
