Oscillating mirror correcting system and correcting method thereof

Abstract

The present invention is suitable for the technical field of laser processing, and provides an oscillating mirror correcting system and a correcting method thereof. The oscillating mirror correcting system comprises the following components: an oscillating mirror correcting plate which is formed with a matrix target through controlling laser by an oscillating scanning module; a CCD image collector which is used for executing image collection to the rectangular target on the oscillating mirror correcting plate; and an image processing module which is used for outputting an oscillating mirror compensation file for correcting the oscillating mirror after the matrix target collected by the CCD image collector is processed. The oscillating mirror correcting system provided by the invention adopts the CCD image collector for executing image collection to the matrix target on the oscillating mirror correcting plate and outputs the oscillating compensation file for correcting the oscillating mirror after the collected matrix target is processed through the image processing module. The correction to oscillating mirror can be realized simply, conveniently and quickly without an auxiliary device.

Description

technical field [0001] The invention belongs to the technical field of laser processing, and in particular relates to a vibrating mirror correction system and a correction method thereof. Background technique [0002] In laser processing technology, the galvanometer is generally used to control the optical path to process various complex graphics and characters; due to interference, motor lost steps, etc., the galvanometer will deviate after a certain period of time, resulting in There is a deviation between the area scanned by the galvanometer and the interface between the areas. At this time, error compensation should be performed on the galvanometer to reduce this deviation. [0003] The traditional technology is to make a matrix target on the calibration board, and then combine with auxiliary measuring equipment (such as the second element, etc.) to measure, manually calculate the deviation between theory and reality, and then generate a calibration file through compensa...
