Abstract
The invention relates to an ultra-high-precision positioning worktable driven by an electromagnetic force. The ultra-high-precision positioning worktable comprises a base, a linear guide track and a sliding table, wherein the linear guide track is fixedly arranged on the base; the sliding table matched with the linear guide track linearly moves in a reciprocating manner; a magnet is arranged on a surface, which is opposite to the base, of the sliding table; a coil is arranged on the base and below the magnet; a grating scale is also arranged at the lower end of a side surface of the sliding table; and an inductive head is fixedly arranged on the base and below the motion trail of the grating scale. By the technical scheme, the worktable can be pushed by a large force, so that the worktable can be positioned in a high-speed, high-precision and high-responsiveness manner. In addition, an electromagnetic driving mode is adopted, and only the linear guide track is arranged on a mechanical contact portion, so that high cleanliness, low noise and even zero noise can be realized.
Description
Technical field
The present invention relates to automation field, be specifically related to a kind of with the power-actuated superhigh precision positioning table of electromagnetism.
Background technology
In the microelectronics processing industry, the manipulator that needs high position precision is inlayed in various electronic circuit board processing, and the core positioning element of manipulator is exactly positioning table, general positioning table adopts the driven by motor leading screw, drive again the motion structure of workbench by leading screw, use this structure that higher positioning precision is arranged, but the miniaturization along with electronic equipment, precise treatment trend, this screw-driven positioning table is subject to the many characteristics of Mechanical Contact part own, Mechanical Contact such as leading screw and feed screw nut, the Mechanical Contact of leading screw and shaft coupling, the Mechanical Contact of shaft coupling and motor, workbench and contacting of line slideway etc., precision is difficult to increase significantly again, and the Mechanical Contact face is many, also can bring lubricated, clean the problem with noise.
Summary of the invention
