Laser processor, laser processing system, and method for mounting cartridge

A laser processing system comprising:

• a workpiece support configured to support a workpiece to be processed by a laser beam;
• a drive device;
• a controller configured to control the drive device;
• and
• a laser processor comprising:
• a machining head configured to radiate the laser beam toward the workpiece and configured to be moved by the drive device relative to the workpiece support;
• a laser source;
• an optical transmission member configured to transmit the laser beam from the laser source to the machining head;
• the machining head having an optical path of the laser beam and comprising:
• a pressing member;
• and
• a stopper surface;
• and
• a cartridge configured to be inserted in the machining head and configured to be pressed by the pressing member when the cartridge is in the machining head, the cartridge comprising:
• an optical component disposed on the optical path when the cartridge is in the machining head, the optical component having a first surface and a second surface opposite to the first surface along the optical path;
• a first member having an upper surface and a lower surface opposite to the upper surface along the optical path, the first member being configured to contact the first surface of the optical component, the lower surface of the first member being configured to contact the pressing member;
• and
• a second member configured to contact the second surface of the optical component and the stopper surface, an uppermost surface of the upper surface of the first member contacting the second member,
• wherein the second member has an upper surface and a lower surface opposite to the upper surface along the optical path, and
• wherein a lowermost surface of the lower surface of the second member contacts the first member.

A method for mounting a cartridge on a laser processor having a machining head, comprising:

• providing the cartridge which includes a first member, a second member, and an optical component which has a first surface and a second surface opposite to the first surface and which is provided between the first member and the second member such that the first surface and a second surface face the first member and the second member, respectively;
• inserting the cartridge in the machining head having an optical path of a laser beam such that the optical component is positioned in the optical path, the first member having an upper surface and a lower surface opposite to the upper surface along the optical path;
• and
• pressing, using a pressing member, the first member toward a stopper surface of the machining head so that the first member presses the first surface of the optical component toward the stopper surface and so that the second surface of the optical component presses the second member to the stopper surface,
• wherein, during the pressing, the lower surface of the first member contacts the pressing member, and an uppermost surface of the upper surface of the first member contacts the second member,
• wherein the second member has an upper surface and a lower surface opposite to the upper surface along the optical path, and
• wherein, during the pressing, the upper surface of the second member contacts the stopper surface, and a lowermost surface of the lower surface of the second member contacts the first member.
