Abstract

A laser oscillator of a laser processing system includes a light emitting part for emitting a laser beam, a power source for supplying electric power to the light emitting part so as to emit a laser beam, and a laser controlling part for controlling the power source. Both the light emitting part and the laser controlling part are provided in a support structure, which is movable away from a laser processing apparatus, and are movable together with the support structure.

First claim

1 . A laser processing system comprising:
a laser oscillator; and a laser processing apparatus configured to process a workpiece by using a laser beam emitted from the laser oscillator, the laser processing apparatus comprising:
an actuation mechanism configured to move the workpiece relative to the laser processing apparatus; and
a mechanism controlling part configured to control the actuation mechanism,
the laser oscillator comprising:
a light emitting part configured to emit a laser beam;
a power source configured to supply electric power to the light emitting part so as to emit a laser beam from the light emitting part; and
a laser controlling part configured to control the power source;
wherein the light emitting part and the laser controlling part are provided in a support structure which is movable away from the laser processing apparatus and are movable together with the support structure.

2 . The laser processing system according to claim 1 , wherein the power source is further provided in the support structure and movable together with the support structure.

3 . The laser processing system according to claim 1 , wherein the support structure further comprises a movable part which is movable independently of the support structure, and wherein at least one of the light emitting part, the power source, and the laser controlling part is provided in the movable part so as to be movable together with the movable part independently of the support structure.

4 . The laser processing system according to claim 1 , wherein the laser processing apparatus further comprises an amplifier configured to supply electric power to the actuation mechanism, and wherein the amplifier is provided in the support structure and movable together with the support structure.

5 . The laser processing system according to claim 3 , wherein the laser processing apparatus further comprises an amplifier configured to supply electric power to the actuation mechanism, and wherein the amplifier is provided in the movable part and movable together with the movable part independently of the support structure.

6 . The laser processing system according to claim 1 , wherein the laser processing apparatus is a processing tool which comprises a plurality of tools being exchangeable, and wherein one of the plurality of tools is a processing head configured to output a laser beam emitted from the light emitting part.

7 . The laser processing system according to claim 1 , wherein the laser processing apparatus comprises a multiple-joint robot, wherein a processing head configured to output a laser beam emitted from the light emitting part is attached to a wrist of the multiple-joint robot, and wherein the support structure is provided in a housing accommodating a control apparatus configured to control the multiple-joint robot.

8 . The laser processing system according to claim 1 , wherein the support structure is provided in a housing of the laser processing apparatus.

9 . The laser processing system according to claim 1 , wherein the laser oscillator is a fiber laser oscillator.

10 . The laser processing system according to claim 1 , wherein the mechanism controlling part and the laser controlling part are configured by a common control apparatus.
