刀具编码的激光自适应标刻技术

Self-adaptive laser marking technology for marking code on tool

针对激光标刻刀具编码时出现的标刻效率低、标刻质量不稳定、危害工人身体等问题,提出了一种自适应标刻技术.设计了特定结构的输送机和V型块,配合光电开关的检测功能实现自适应传送刀具;设计了使不同刀具在抓取后轴线处在同一位置的机械手爪,以保证不同刀具端面都能快速定位到激光头标刻区域;利用机械手的快速移动,采用了光电开关辅助对焦来提升对焦的速度和精度.在这3项关键技术支持下,完成了整个方案的设计.样机的测试结果表明,相比传统标刻方式,自适应标刻技术能将标刻效率提升4倍以上,保证标刻编码质量稳定可靠,实现无人化标刻.

In view of the recent situation that several defects of traditional laser marking code on tool ap- pear such as marking inefficiency, marking quality instability and the harm to workers, a self-adaptive laser marking technology was put forward. The conveyor and V-block of specific structure were designed with photo- electric switch detection function to realize self-adaptive tool delivery. Besides, a kind of gripper was devel- oped that made the different tool axes stand in the same position after grasping, which ensured that all of the different tool ends could quickly locate to laser marking area. Moreover, using the rapid moving of gripper, a photoelectric switch was adopted auxiliary focus to improve the speed and precision of focusing. Under the sup- port of the three key technologies above, the whole design of project was completed. The test results of proto- type prove that the self-adaptive laser marking technology increases the marking efficiency of more than four times compared with that of the traditional way and ensures the marking quality reliably. This technology achieves the goal of unmanned marking.
