一种用于激光材料加工的非同轴定位装置及方法

Non-coaxial positioning apparatus for processing laser material and method

Abstract

本发明是一种用于激光材料加工的非同轴工件加工点定位装置及方法,属于材料加工领域。包括CCD摄像机、图像采集卡、控制电路、固定装置和计算机。通过固定装置将CCD摄像机、控制电路固定到在激光加工头上。通过在材料废料处预加工,移动激光加工头使CCD摄像机对预加工图案进行成像定位,确定出CCD摄像机与激光加工头的相对位置,之后用CCD摄像机代替激光加工头对需要加工的工件部位进行空走预加工,观察加工路径是否符合要求,如不符合,调整加工路径、加工补偿和工件位置直至符合加工要求,最后移动激光加工头到CCD摄像机位置,进行最终的激光加工。该发明无需改变现有激光加工头的构造,装配简易,整个定位过程快速,精度高。
The invention provides a non-coaxial workpiece processing point positioning device and a method used for the processing of laserable material, belonging to the field of material processing. The device comprises a CCD camera, an image collecting card, a control circuit, a fixing device and a computer. The CCD camera and the control circuit are fixed on a laser processing head by the fixing device. By the pre-processing at the waste material position of the material, the laser processing head is moved to lead the CCD camera to carry out the image location of the pre-processed images and determine the relative position of the CCD camera and the laser processing head; subsequently, the CCD camera is used for replacing the laser processing head to carry out the idling pre-processing of the workpiece position required to be processed; whether the processing path complies with the requirement is observed; if not, the processing path, processing compensation and workpiece position are adjusted till the processing requirement is complied with; the laser processing head is finally moved to the CCD camera position to carry out the final laser processing. The device and method of the invention need not to change the structure of the existing laser processing head, and have simple and easy assembly, fast positioning speed in the whole positioning process and high precision.
