Multi-degree-of-freedom laser processing robot

The invention relates to the technical field of multi-axis robots, and discloses a multi-degree-of-freedom laser processing robot which comprises a workbench, a support arranged on the workbench, a laser generator installed at the bottom of the support and a basic light guide arm connected with the laser generator, and the other end of the basic light guide arm is connected with a plurality of rotating light guide units capable of relatively rotating in series. A light emitting device is mounted at the tail end of the last rotary light guide unit; the rotating light guide unit comprises a rotating joint, a light guide arm and an L-shaped bent pipe, one end of the rotating joint is coaxially and rotatably connected with the light guide arm, the rotating joint and the light guide arm rotate relatively through a rotating driving module, and the other end of the light guide arm is connected with one end of the bent pipe. Through the design, the laser generator can be moved to the workbench from the tail end of th
