Abstract

The present invention provides a single-degree-of-freedom large-stroke nano-displacement positioning platform based on flexible hinges, including a platform main body. There are four flexible hinges on the platform main body, and the platform main body is divided into A zone, B zone and C zone by the four hinges. , four parts of D area, the A area is a moving area, the B area and C area are force deformation areas, and the D area is a fixed area; the two ends of the main body of the platform are provided with a left blind hole and a right blind hole, The bottom of the left blind hole is a smooth conical surface, and a spring preload assembly is installed inside it, and the bottom of the right blind hole is also a smooth conical surface, and a piezoelectric ceramic assembly is installed inside it, and the spring preload assembly is installed inside it. The component and the piezoelectric ceramic component constitute the amplification mechanism. The invention realizes relatively large vertical displacement under the condition of small vertical platform size, and can meet the requirement of occasions with small space but large vertical travel.

Description

technical field [0001] The invention provides a nano-displacement positioning platform capable of realizing a large displacement stroke in the vertical direction, and ensures a small size in the vertical direction, so as to meet the actual application occasions where the space in the vertical direction is small. Background technique [0002] The nanopositioning platform is used to generate nanometer-level displacement and realize nanometer-level positioning control. It is mainly used in high-tech industries such as atomic force microscopes, precision optical equipment, and semiconductor equipment. The development of advanced semiconductor chip manufacturing technology and large-scale memory manufacturing technology has pushed nano-displacement and nano-positioning technology to a new height. Precision measurement and detection technology is considered to be the technical bottleneck that must be broken through in next-generation semiconductor chip manufacturing technology and...
