Description

Laser marking high precision calibration measuring device

technical field

The utility model belongs to the field of measurement, in particular to a laser marking high-precision calibration measurement device.

Background technique

At present, as long as the laser marking industry is involved, there will be distortion in the scanning range of the galvanometer, and this distortion must be processed through coordinate points. Since the galvanometer will cause positioning distortion due to the distortion of the optical path and the focusing lens during scanning, it is necessary to calibrate this distortion. The calibration work needs to be completed before the laser equipment leaves the factory. Once the calibration is completed, it does not need to be performed again. Unless the accuracy cannot meet the requirements after using for a long time, it can be recalibrated. Calibration is a relatively fine adjustment. It is recommended that non-professionals do not do it, otherwise it will be counterproductive.
