Laser equipment adjusting method based on temperature compensation

Abstract

The invention relates to the technical field of laser equipment adjusting, in particular to a laser equipment adjusting method based on temperature compensation. The method comprises the steps that atemperature sensor is used for detecting the temperature of a galvanometer motor and a laser device, an angle sensor is used for detecting the angle of a galvanometer, the detected temperature value and the detected angle value are transmitted to a controller, and the controller adjusts the torque of the galvanometer motor, the power of the laser device and the angle of the galvanometer accordingto the detection result, the torque correction function, the current correction function and the angle correction function. On the basis of the temperature compensation principle, through combined application of the torque correction function of the galvanometer motor, the angle correction function of the galvanometer and the current function of the laser device, compensative adjusting is conducted on the torque of the galvanometer motor, the angle of the galvanometer and the power of the laser device, influences caused to the torque of the galvanometer motor, the angle of the galvanometer andthe power of the laser device due to temperature rising are eliminated, and the galvanometer motor, the galvanometer and the laser device can stably, reliably and continuously efficiently work.

Description

technical field [0001] The invention relates to the technical field of laser equipment adjustment, in particular to a temperature compensation-based laser equipment adjustment method. Background technique [0002] Laser processing is the most common application for laser systems, of which laser thermal processing is the most common form of application.
