Abstract:
1. A laser processing apparatus for processing a workpiece having a surface to be processed, the laser processing apparatus comprising: a worktable comprising a supporting surface for loading the workpiece thereon; a laser emitter configured for emitting a laser beam and focusing the laser beam, the laser emitter having a focal length; a driving device configured for adjusting a height of the laser emitter relative to the supporting surface along a direction substantially perpendicular to the supporting surface; a user interface allowing to input a thickness value of the workpiece; a detecting unit, comprising: a controller electrically connected to the laser emitter, the driving device, the user interface and the detecting unit, the controller being configured for controlling the lifting device to adjust the height of the signal emitter and the signal receiver to be equal to a sum of the input thickness value and the focal length of the laser emitter, and controlling the driving device to adjust the height of the laser emitter if the signal receiver receives the detecting signals and controlling the driving device to stop to adjust the laser emitter if the signal receiver does not receive the detecting signals.
