即時三維建模之雷射飛行打標系統及其方法Real-time three-dimensional modeling laser flight marking system and method thereof

本發明是關於一種雷射飛行打標系統及其方法,特別是關於一種即時三維建模之雷射飛行打標系統及其方法。The present invention relates to a laser flying marking system and method thereof, and more particularly to a laser three-dimensional modeling laser flying marking system and method thereof.

目前,三維雷射飛行打標技術主要是先讀取工件的圖像模型,例如CAD檔等或者利用三維建模的方式取得工件的完整三維模型,然後將讀取的圖像模型或者經由建模得到的完整三維模型進行分區,利用雷射刻印頭移動至各區,來對各區進行打標,但換言之,現有技術具有以下的缺點:首先,需先取得工件的圖像模型或者完整三維模型,否則將無法進行後續的加工動作;再者,對於少量且多樣的加工情況,三維建模會耗費許多時間;另外,分區塊進行打標的方式,則在打標的過程中,雷射刻印頭或者工件需要經過多次移動、停頓及打標的流程,因此無法一次性的飛行打標,而造成速度慢且在色澤及紋路的連續性上亦相對較差;以及目前三維雷射飛行打標僅針對較簡單的曲面的工件進行打標,例如:圓柱面或球面等,而對於較複雜的曲面,仍然存在著打標精度不高的問題。At present, the three-dimensional laser flight marking technology mainly reads an image model of a workpiece, such as a CAD file, or obtains a complete three-dimensional model of the workpiece by using three-dimensional modeling, and then reads the image model or via modeling. The obtained complete three-dimensional model is partitioned, and the laser marking head is moved to each area to mark each area, but in other words, the prior art has the following disadvantages: First, an image model or a complete three-dimensional model of the workpiece needs to be obtained first. Otherwise, subsequent processing operations will not be possible; in addition, for a small number of different processing situations, 3D modeling will take a lot of time; in addition, the marking method of the partitioning block in the marking process, the laser marking head or The workpiece needs to go through multiple movements, pauses and marking processes, so it is impossible to mark the flight at one time, resulting in slow speed and relatively poor continuity in color and texture; and the current 3D laser marking is only for Simple curved surface workpieces, such as cylindrical or spherical surfaces, but for more complex surfaces, there is still a fight Accuracy is not high.
