Problems solved by technology

Since the calibration accuracy of the galvanometer is often reflected by the connection of the scanning area of ​​the galvanometer, but because the direct reading of the calibration coordinates requires cumbersome calculations and procedures, the detection process of this method is more complicated and the efficiency is not high.

Abstract

The invention provides a laser precision galvanometer calibration accuracy detection method and a detection system. The method comprises the following steps: verification material is arranged on the boundary of at least one galvanometer scanning area; the verification material is at least arranged on the boundary in the two mutually-perpendicular directions; a plurality of partially-standard patterns are respectively processed on the verification material by laser, so that the partially-standard patterns are spliced to form at least one standard pattern; whether the integrity of the standard pattern after being spliced reaches a preset value is detected, therefore, the accuracy of a galvanometer can be judged. According to the laser precision galvanometer calibration accuracy detection method and the detection system, the detection and verification process for the calibrated galvanometer is simplified, the detection efficiency is improved, and the calibration accuracy of the galvanometer can be rapidly and accurately detected and verified.

Description

Technical field [0001] The invention relates to the technical field of laser precision processing, in particular to a method and system for detecting the correction accuracy of a laser precision galvanometer. Background technique [0002] In the field of laser precision cutting, the processing method of galvanometer scanning is usually used to ensure the processing accuracy of the laser precision system. In the laser precision system using the galvanometer, the galvanometer scanning system needs to be calibrated through the software control system interval of the galvanometer. This process is called the correction of the galvanometer. After the galvanometer is corrected, it is necessary to check and evaluate the accuracy of the correction to determine whether the laser processing accuracy meets the requirements. [0003] The existing method for detecting the correction accuracy of the galvanometer is to directly read the corrected compensation coordinates through software, and per...
