dot mark 刻印標記。

dot pattern

The innovat ions of this thesis are as follow : by using dots marking method we achieve high on - line marking , and we design the accurate orientation project , the high scan project , and the step scan project , each of them can be applied for different marking requirement the main contents of thesis are as follows : 1 the development of laser industry , the prospect and technically advantage of laser marking is reviewed 本文的創新之處為,采用點陣式標記方法實現了高速在線打標功能,并分別設計了精確定位方案、快速掃描方案和分步掃描方案三種不同的打標方案,可適用于不同的在線打標要求。主要內容如下: 1 、分析了國內外激光加工業特別是激光打標機及其市場現狀、發展趨勢和市場前景等。

3 for dots marking , we design a convenient software , it can pick - up the characters dots information directly from dots characters - library , then make it more convenient for user . 4 two type of laser markers have been used to some product - lines . three different projects are developed 4 、為了實現在線激光打標功能,分別提出了精確定位方案、快速掃描方案和分步掃描方案三種不同的打標方案,三種打標方案均采用點陣字符打標,分別可適用于不同的在線打標要求。
