Abstract: A laser processing head is provided with: an optical component for splitting a laser light into a laser light and a laser light; a scanning unit for scanning the laser light; a light reception unit for detecting the intensity of the laser light; a second shutter that shifts between a closed position in which the laser light is blocked and an open position in which the laser light is transmitted; and a focal distance adjustment unit for adjusting the focal distance of the laser light. The second shutter is arranged between the optical component and the focal distance adjustment unit.

Abstract: A focal length adjusting device is provided with: a retention unit for retaining a first lens; a guide unit for supporting the retention unit so as to allow movement along an optical axis of laser light; a stepper motor that has a shaft body and is arranged so that the central axis of the shaft body is orthogonal to the optical axis; and a conversion unit that is interposed between the shaft body and the retention unit and converts rotational movement of the shaft body into linear movement of the retention unit. The conversion unit comprises, between itself and the retention unit, a coupling unit that transmits kinetic force from the conversion unit to the retention unit in a direction parallel to the optical axis but does not transmit same in a direction parallel to the central axis of the shaft body.

Abstract: In the present invention, a head connector comprises an optical axis adjustment unit that adjusts the optical axis of a laser beam emitted from a tip of an optical fiber cable, and a spread angle adjustment unit that adjusts the spread angle of emitted light. The optical axis adjustment unit comprises an operation unit configured to be operable from a lateral-surface side of the head connector, and a movement unit that moves a fiber holder within a plane orthogonal to the optical axis of the emitted light in response to an operation of the operation unit. The spread angle adjustment unit comprises an operation unit provided to an insertion unit to be inserted into a laser head, and a movement unit that moves a lens in response to the operation of the operation unit.

Abstract: A laser processing device comprises: a first shutter that shifts between a closed-state position for blocking a laser beam and an open-state position for allowing the laser beam to pass; a second shutter that shifts between a closed-state position for blocking laser beams and an open-state position for allowing the laser beams to pass; a first closed-state sensor that detects that the first shutter is disposed at the closed-state position; a first open-state sensor that detects that the first shutter is disposed at the open-state position; a second closed-state sensor that detects that the second shutter is disposed at the closed-state position; and a second open-state sensor that detects that the second shutter is disposed at the open-state position.
