AI Technical Summary
In existing multi-laser devices, it is difficult for the focal positions of each laser beam to be simultaneously at the optimal working plane. The focusing process is cumbersome and affects the continuous operation of the equipment. After focusing, it is difficult to quickly return to the reference zero point position, and it is impossible to achieve truly independent fine focusing.
A multi-stage fine-tuning assembly consisting of a coarse-tuning mechanism, a small-stroke spiral fine-tuning mechanism, and a sensor-based fine-tuning mechanism, combined with a wedge-shaped locking block assembly and a locking slot, enables independent focusing of each laser module. Errors are compensated by sensor feedback to ensure the accuracy and consistency of the focus position.
This allows each laser module to independently reach its optimal focal position during additive manufacturing, improving the repeatability and consistency of focusing, simplifying the focusing process, and enhancing operational stability and convenience.
