Abstract
A decoupled XY parallel micro-positioning stage, including a central moving platform, fixed mechanisms, bridge-type micro-displacement amplification mechanisms, a four-bar symmetrical flexible guide mechanism and a piezoelectric ceramic. Each fixed mechanism is arranged between adjacent amplification mechanisms and is symmetrical about X and Y axes centered on the moving platform. The amplification mechanism is symmetrically arranged with respect to the X and Y axes, and includes two first and second longitudinal beams and multiple crossbeams. The two first longitudinal beams are provided in parallel and spaced apart. The two second longitudinal beams are arranged spaced apart between the two first longitudinal beams, and are connected to the two first longitudinal beams via the crossbeams. The crossbeams are connected to the longitudinal beams via a flexible hinge. The piezoelectric ceramic is arranged between the two first longitudinal beams.
