Self-adaptive laser marking technology for marking code on tool

In view of the recent situation that several defects of traditional laser marking code on tool appear 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 photoelectric switch detection function to realize self-adaptive tool delivery. Besides, a kind of gripper was developed 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 support of the three key technologies above, the whole design of project was completed. The test results of prototype 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.
