Abstract

The invention relates to a graph on-line splicing method and system for laser processing of a large format, and solves the problem that the splicing accuracy of an existing on-line splicing method cannot meet the processing requirement. The graph on-line splicing method comprises the following steps of 1) dividing a to-be-processed graph into N sub graphs, and acquiring the coordinate of the center point of each sub graph and the smallest rectangular region containing each sub graph; 2: turning on an indication power supply, enabling light beam emitted by the indication power supply to reach an X to-be-processed area, and scanning the boundary of the X to-be-processed area; 3) observing the X to-be-processed areas by a coaxial measuring unit, acquiring the images of the X to-be-processed areas, and obtaining the actual bounding box of the X to-be-processed areas by the control unit according to the acquired image; 4) comparing a theory bounding box with an actual bounding box; 5) adjusting the positions of X sub graphs in the control unit; and 6) completing the graph scanning of the X processing areas; and 7) repeating the step 2 to the step 6.

Description

technical field [0001] The invention relates to laser precision processing technology, in particular to an online splicing method and system for graphics used in large-format laser processing. Background technique [0002] With the wide application of laser processing technology, the advantages of laser processing are also reflected. Its main advantages are non-contact processing, small thermal influence, wide range of processing materials, etc. Due to the unique advantages of laser processing, it plays an important role in micro-nano processing. playing an increasingly important role. With the gradual expansion of laser processing range, higher and higher requirements are put forward for the precision and stability of laser micromachining technology. [0003] Due to the advantages of fast processing speed, high precision, and strong environmental adaptability, laser scanning galvanometers have become the main components of laser processing, and are increasingly used in las...
