Description

Technical Field

[0001] The utility model relates to the technical field of marking machines, in particular to an automatic positioning and focusing laser fiber marking machine. Background Art

[0002] Fiber laser marking machines use laser beams to permanently mark the surfaces of various materials. The effect of marking is to expose the deeper material through the evaporation of the surface material, or to make marks through the physical changes of the surface material caused by light energy, or to burn away part of the material through light energy to reveal the required etching patterns, text, barcodes and other graphics. The existing laser marking machines basically meet user needs, but there are still certain defects. The existing laser marking machines need to place the marked products in a fixed position during marking. For products with height differences, a limiting structure needs to be added. Marking some batch products is time-consuming and labor-intensive, which greatly affects the marking speed. In addition, the existing laser marking machines have a complex structure, high manufacturing cost, and inconvenient later maintenance. Therefore, it is very necessary to design an automatic positioning and focusing laser fiber marking machine. Utility Model Content
