Long-stroke two-dimensional nano worktable system with angle compensation function
The invention discloses a long-stroke two-dimensional nano worktable system with an angle compensation function. A six-degree-of-freedom micro table designed on the basis of a piezoelectric ceramic actuator and a soft hinge chain carries out comprehensive compensation of linear positioning and angle errors on a long-stroke two-dimensional nano worktable. A driving mode that a stepping motor and a ball screw are combined is adopted, so a long-stroke two-dimensional nano worktable has a large pitching angle, a deflection angle and roll angle errors, and positioning precision is of micron size. The six-degree-of-freedom micro table has nanoscale linear positioning precision and millisecond-level angle positioning precision. The long-stroke two-dimensional nano worktable and the six-degree-of-freedom micro table are combined to form the long-stroke two-dimensional nano worktable system. Under control of a closed-loop control system, the six-degree-of-freedom micro table carries out the comprehensive compensation of the linear positioning errors and the angle errors on the long-stroke two-dimensional nano worktable, so two-dimensional long-stroke nano positioning is achieved.
