Abstract

The invention relates to the technical field of high-precision motion, in particular to a large-stroke flexible hinge platform. The large-stroke flexible hinge platform comprises a supporting base, aconnecting frame, a micro bearing platform, an X-axis flexible hinge sheet and a Y-axis flexible hinge sheet, wherein the two ends of the X-axis flexible hinge sheet are separately fixed onto the connecting frame and the supporting base; the two ends of the Y-axis flexible hinge sheet are separately fixed onto the connecting frame and the micro bearing platform; and rigidity of the flexible hingesheet can be regulated by regulating a clamping position, so that matching of variable working conditions is realized. The large-stroke flexible hinge platform utilizes a rigidity-adjustable flexiblehinge to realize multi-axis dynamic characteristic coordination, and utilizes nonlinear elastic deformation of the flexible hinge to realize large-stroke high-speed interpolation, so that efficient processing is realized.

Description

technical field [0001] The invention relates to the technical field of high-precision motion, and more specifically, to a large-stroke flexible hinge platform and a control method thereof. Background technique [0002] Laser drilling, integrated circuit wire bonding, etc., require frequent operations at the millimeter level. The motion platform is used to realize the interpolation, and the speed is low due to the friction and inertia of the guide rail. If the cross roller guide is used, partial wear of the guide rail will occur. Existing flexible hinges generally have a small stroke, only a few hundred microns. Amplifying mechanisms are required for large strokes, which produce multi-modal superimposed responses at high speeds, making it difficult to achieve precise control. Contents of the invention [0003] In order to overcome at least one defect of the above-mentioned prior art, the present invention provides a large-stroke flexible hinge platform, and the technical...
