MULTI-HEAD LASER PROCESSING METHOD AND DEVICE THEREOF

摘要

A multi-head laser processing method is that the distances( a, b, a+b) between the focus points(H, I, J) of the laser beams after focused are changed by adjusting the position relations between at least two laser beams (A, B, C) before focused. The positions of the laser beams (A, B, C) before focused are adjusted by adjusting the extender lenses (D, E. F), the reflection lenses(Kl, K2, K3) or the laser heads(l, 2, 3). A multi-head laser processing device is also disclosed. By the method and the device, the distances between the multiple processing points can be adjusted, therefore the precision machining is obtained.
