UV Laser Processing Technology of Flapping-wing Microair Vehicles

摘要:

为了实现微米尺度扑翼微飞行器的加工, 运用了加工材料范围广的紫外激光切割技术, 以及碳纤维预浸料的真空袋高温高压固化工艺, 通过合理安排工艺流程, 实现了一种适于微米尺度复杂机械结构、可采用材料广泛且可以小批量快速加工的加工技术。并将其应用于扑翼微飞行器的加工, 得到了一个翼展3cm, 最小尺寸为80μm的飞行器样机。

Abstract:

In this paper, in order to achieve the processing of micron scale flapping wing MAV(micro air vehicle), used is the UV laser processing method which can cut a wide range of materials, and vacuum bag for carbon fiber prepreg curing under high pressure and temperature. By reasonablly arranging the processing sequence, a suitable processing technology for the micron scale complex mechanical structure was realized, which can process a variety of materials rapidly and suit for small-lot production. Applying the technology for flapping wing MAV, an aircraft prototype with wingspan of 3cm and the minimum size of 80μm is obtained.
