Abstract

The invention relates to a plane orientating system with large stroke, high speed nanometer stage precision and macro/micro dual driven. The X-shaft flexible hinge is fixed between the X-shaft micro moving platform 19 and X-shaft macro moving platform 16; the X-shaft piezo-electric ceramic 18 is posited inside the X-shaft micro moving platform 19; the cushioning hinge 29 is fixed between the inner guide 28 and the outer guide 30; one end of Y-shaft piezo-electric ceramic 24 is connected with Y-shaft micro moving platform 23; two bearings 34 are separately rotating connected with inner guide 18 and outer guide 30 of the Y-shaft macro/micro moving platform 8. The working rage is 25mmX25mm; the resolution is 10nm; the repetition orientating precision is 20nm; the maxim speeds of X-shaft and Y-shaft are separately at 50m/s2 and 100m/s2.

Description

Technical field: [0001] The invention relates to a plane positioning system. Background technique: [0002] Integrated circuit (IC) packaging, micro-electromechanical system (MEMS) manufacturing and other fields have an increasingly urgent need for large travel (cm level), high speed (m / s level) and high precision (μm to nm level) positioning systems. However, the current problems are: 1. The traditional planar positioning system of the XY table with a series structure, because the upper platform is used as the work load of the base platform, greatly increases the inertia of the base platform and limits the speed and acceleration of the entire system. The efficiency of the system is low. 2. The existing parallel structure XY workbench type planar positioning system only uses a single drive device such as a rotating motor + ball screw, linear motor or voice coil motor. Although it can achieve a large range of motion, its accuracy is only Can meet micron or sub-micron requirements....
