Embodiment 1
[0034] An embodiment of the present invention provides a method for performing nanosecond pulse laser stripping on a metal plate coating, specifically as figure 1 As shown, the laser beam 4 emitted by the nanosecond pulse laser 1 passes through the energy transmission fiber 2, the collimation head 3 and emits it to the surface of the coating to be stripped through the two-dimensional scanning galvanometer 5, and the coating to be stripped is passed through the nanosecond pulse laser After ablation, an explosive melting reaction occurs, and the metal plate is separated from the metal plate driven by the high-speed airflow generated on the coating surface.
[0035] At the same time, in order to remove the oxides generated after peeling off the coating, after the nanosecond pulse laser ablates the coating to be peeled off, adjust the frequency of the nanosecond pulse laser to quickly vaporize the oxides generated after peeling off the coating and detach from the metal plate .
