Laser processing robot system

A laser processing robot, wherein: a robot; laser processing tool; fiber; and a wiring channel. 1 includes a first arm member and the second member. Continuously via wiring is formed in the interior of the first member and the second member, an optical fiber inlet port disposed in the first distribution passage member, while the optical fiber outlet port provided in the wrist portion of the wiring passage of the second member. The laser processing tool includes: a mounting portion, relatively perpendicular to the second control shaft of the first control shaft is swingably mounted on the wrist portion; a nozzle portion having a laser passage axis along the second control axis intersecting extending from extending mounting portion; and a reflective portion, equipped with the mounting portion, the reflected laser light emitted from the optical fiber, the laser and the guide passage. Output end face of the optical fiber is positioned between the optical fiber outlet port to the laser processing tool to a reflecting portion provided in the wrist portion.
