【摘要】：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.
[Abstract]:In order to solve the problems of low efficiency, unstable quality and harmful to workers' health in laser marking tool coding, an adaptive marking technique is proposed, and a special structure conveyor and V-shaped block are designed. With the detection function of photoelectric switch, the self-adaptive transfer tool is realized. The manipulator claws with different cutting tools in the same position after grabbing axis are designed to ensure that the end faces of different cutting tools can be positioned to the laser head marking area quickly. With the help of the rapid movement of the manipulator, the photoelectric switch auxiliary focus is used to improve the speed and accuracy of the focusing. The design of the whole scheme is completed with the support of these three key technologies. The test results of the prototype show that the system can improve the speed and accuracy of the system. Compared with the traditional marking method, the adaptive marking technology can improve the efficiency of marking by more than 4 times, ensure the quality of marking coding stable and reliable, and realize the non-human marking.
