Problems solved by technology
The disadvantages are: firstly, the time required for workpiece movement prolongs the entire processing time and reduces the processing efficiency; secondly, the vibration caused by the relative movement also easily reduces the stability of the laser; in addition, when high-precision laser marking is required When the high-precision transmission equipment will greatly increase the system cost

The invention relates to a quick laser marking system with a time division light path and an ultra large format. The ultra-large-format quick laser marking system comprises a laser device (1), a beam expanding mirror (2) and a Faraday rotator (3) as well as at least two sets of galvanometer systems (6A, 6B, 6C), wherein polarizing films (4A, 4B) or a completely reflecting mirror (7) is arranged in front of each of the galvanometer systems (6A, 6B, 6C) respectively; the polarizing films (4A, 4B) and the completely reflecting mirror (7) together form the time division light path; and the incident end of the time division light path is connected with the Faraday rotator (3), so that the incoming light of the Faraday rotator (3) is transmitted or refracted by the polarizing films (4A, 4B) or the completely reflecting mirror (7) and then sent to each of the galvanometer systems (6A, 6B, 6C). The quick laser marking system is an ultra-large-format laser marking system with the advantages of no relative movement of the galvanometer systems and processed workpieces, high processing speed, high marking accuracy and easily expanded format.
Description
【Technical field】 [0001] The invention relates to a laser marking system, in particular to a time-division optical path ultra-large format fast laser marking system. 【Background technique】 [0002] As a modern industrial processing technology, laser marking (laser marking engraving) is widely used in various metals, such as stainless steel, aluminum, copper; plastic, rubber, etc. Text and pattern marks on other materials, such as trademarks, production dates, barcodes, company registration patterns, etc. The laser marking system includes: a laser, a laser beam expander, and a vibrating mirror system. The laser emitted by the laser passes through the laser beam expanding mirror and enters the vibrating mirror system to engrave the workpiece. The existing laser marking system has only one set For the galvanometer system, when performing large-format laser marking, it is necessary to use a long focal length field lens to expand the marking format. If a larger-format laser mark...
