Problems solved by technology

However, the existing flexible hinges generally have a small stroke, only a few hundred microns
For large strokes, an amplification mechanism is required, which produces multi-modal superimposed responses at high speeds, making it difficult to achieve precise control

Abstract

The invention relates to a high-speed precision laser drilling platform and a control method thereof. The high-speed precision laser drilling platform includes: a macro XY movement platform, a micro XY movement platform, and a working suction cup; the micro XY movement platform is installed on the macro XY movement On the platform; the micro-XY motion platform includes: a support seat, a connecting frame, a micro-bearing platform, an X-axis flexible hinge piece, and a Y-axis flexible hinge piece; the two ends of the X-axis flexible hinge piece are respectively fixed on the connecting frame on the support seat; the two ends of the Y-axis flexible hinge piece are respectively fixed on the connecting frame and the micro-carrying platform; the micro-carrying platform is also provided with a micro-X-axis encoder and a micro-Y-axis The encoders are respectively used to measure the motion information of the X / Y direction of the micro-carrying platform; the working suction cup is installed on the micro-carrying platform of the micro-XY motion platform. The invention utilizes the elastic deformation of the flexible hinge to realize high-speed interpolation and realize high-speed and precise positioning between holes.

Description

technical field [0001] The present invention relates to the technical field of laser drilling platforms, and more specifically, to a high-speed and precise laser drilling platform and a control method thereof. Background technique [0002] The motion platform of the existing laser microhole array processing equipment mainly adopts the mechanical guide rail type linear motor platform, which can only process 2-3 holes per second due to the influence of friction. Foreign countries use cross ball guide rail platforms, which have low friction and can reach 10 holes per second, but the price is expensive, and the efficiency is still far below the technological limit of hundreds of holes per second. The main movement of laser microhole array processing is high-speed precision positioning between hole centers + high-speed precision interpolation movement of microholes. If the interpolation movement adopts a frictionless flexible hinge mechanism, an interpolation frequency of tens o...
