Abstract

The invention relates to a laser galvanometer accuracy on-line correction system and method. The system comprises a control device, a workbench for placing a workpiece, a first imaging device, a lasergalvanometer and a second imaging device; the workbench comprises a loading workstation, a processing workstation and a detection workstation which are sequentially arranged; the first imaging deviceis arranged at the loading workstation; the laser galvanometer is arranged at the processing workstation; the second imaging device is arranged at the detecting workstation; and the control device iselectrically connected with the workbench, the first imaging device, the laser galvanometer and the second imaging device. By adopting the technical scheme of the invention, on-line correction of thelaser galvanometer can be realized, and the laser processing efficiency is greatly improved.

Description

technical field [0001] The invention relates to the technical field of laser processing, in particular to an online calibration system and method for the precision of a laser vibrating mirror. Background technique [0002] When laser is used for graphic processing of workpiece, the laser beam is usually first emitted by the laser, and then the laser beam is scanned at high speed by the laser galvanometer to act on the workpiece, and finally the corresponding graphic processing is completed. With the long-term use of the laser galvanometer, its accuracy will change due to external factors such as ambient temperature, humidity, vibration, and its own temperature drift. In order to ensure the accuracy of graphic processing, the laser galvanometer needs to be calibrated irregularly. However, when correcting the laser galvanometer at present, it is necessary to check after the system is shut down, which seriously affects the efficiency of laser processing.
