Description

Technical Field

[0001] The utility model belongs to the technical field of laser marking equipment, and particularly relates to a laser marking device with a dust removal function. Background Art

[0002] Laser marking machines use laser beams to pit and evaporate the surface materials on various surfaces, exposing the deeper materials, thereby obtaining the desired pattern.
