ABSTRACT:
An exemplary laser cutting device (300) includes a laser source (40), a lens module (51), a sprayer (60), a rotating subassembly (52), and a driving member (55). The lens module is configured for focusing a laser beam emitting from the laser source. The sprayer is rotatably connected to the lens module. The rotating subassembly is connected to the lens module. The rotating subassembly is configured for driving the lens module to rotate, such as to make the laser beam rotate relative to an axis of the laser beam. The driving member is connected to the lens and configured for driving the sprayer to rotate relative to the lens module.
