Abstract

The invention discloses a large-stroke three-dimensional nano flexible moving platform. The platform comprises a substrate; a terminal platform; an X-direction driver and a Y-direction driver; a first Z-direction flexible decoupling device and a second Z-direction flexible decoupling device, wherein one end of the first Z-direction flexible decoupling device and one end of the second Z-direction flexible decoupling device are connected with the terminal platform; a first amplifying rod and a second amplifying rod, wherein the lower end of the first amplifying rod is connected with the substrate through a first lower flexible hinge, and the upper end of the first amplifying rod is connected with the first Z-direction flexible decoupling device through a first upper flexible hinge. The lower end of the second amplifying rod is connected with the substrate through a second lower flexible hinge, and the upper end of the second amplifying rod is connected with the second Z-direction flexible decoupling device through a second upper flexible hinge. The X-direction driver is connected with the first amplifying rod, and the Y-direction driver is connected with the second amplifying rod. The platform provided by the invention is small in plane side, is high in moving precision, and has advantages of centimeter-level large stroke and nano precision.

Description

technical field [0001] The invention relates to a large-stroke three-dimensional nano-flexible motion platform. Background technique [0002] Existing flexible micro-positioning platforms are planar flexible micro-positioning platforms. Specifically, the existing flexible micro-positioning platforms are all made of metal materials through wire cutting. Therefore, the existing flexible micro-positioning platforms have the disadvantages of small travel and large plane size. Contents of the invention [0003] The present invention aims to solve one of the technical problems in the related art at least to a certain extent. Therefore, the present invention proposes a large-stroke three-dimensional nano-flexible motion platform with the advantages of small plane size, high motion precision, and large motion stroke. [0004] The large-stroke three-dimensional nano-flexible motion platform according to the embodiment of the present invention includes: a base; a terminal platfor...
