Patent number: 11951564Abstract: A method determines translational and/or rotational deviations between the measurement coordinate system of a measurement mirror scanner and the processing coordinate system of a processing mirror scanner. A measurement beam reflected at a workpiece returns on a path of an incident measurement beam and is captured by a spatially resolving measurement sensor to ascertain spatially resolving information of the workpiece. The reflected measurement beam, in a sensor image of the measurement sensor, is imaged onto a previously known image position. This is accomplished by ascertaining a focal position deviation of the processing beam by scanning with the processing beam, evaluating a laser power detected at grid points, fixing the processing mirror scanner, capturing spatially resolving height information of the pinhole diaphragm by the measurement sensor, and determining a translational deviation between the processing and measurement coordinate systems based on the deviation.Type: GrantFiled: November 6, 2019Date of Patent: April 9, 2024Assignees: TRUMPF Laser- und Systemtechnik Gm H, TRUMPF Laser GmbHInventors: Martin Stambke, Jan-Patrick Hermani, Thomas Notheis, Alexander Sauter

Publication number: 20140027421Abstract: In a method for determining the focal point or the beam profile of a laser beam, which can be deflected in the x and y directions by a scanner optic or an x-y-movement unit and can be displaced in the z direction by a focusing optic or a z-movement unit, at a plurality of measurement points in the two-dimensional working field or three-dimensional working space of the laser beam. An aperture diaphragm, followed by a detector, is arranged at each measurement point. At each measurement point, for x-y-focal point or beam profile measurements, the laser beam is moved by the scanner optic or the x-y-movement unit in an x-y-grid over the measurement aperture in the aperture diaphragm, and, at each grid point, the laser power is measured by the detector, the scanner axis of the scanner optic or the x-y-movement unit being stationary. For z-focal point measurements, the laser beam is displaced by the focusing optic or the z-movement unit in the z direction within the measurement aperture in the aperture diaphragm.Type: ApplicationFiled: September 30, 2013Publication date: January 30, 2014Applicant: TRUMPF Laser GmbH + KGInventor: Thomas Notheis

Patent number: 7239780Abstract: A device couples a laser beam into a laser light cable having a cable connection for the laser light cable. The device includes a safety element that is operable to move to a safety position only when the laser light cable is properly connected to the cable connection. The coupling device includes an optical arrangement that is controlled by the safety element, and is disposed in the beam path of the laser beam upstream of the cable connection and only directs the laser beam towards the cable connection when the safety element is in the safety position.Type: GrantFiled: June 6, 2006Date of Patent: July 3, 2007Assignee: Trumpf Laser GmbH + Co.

Patent number: 6766117Abstract: The invention provides a network system for laser processing, comprising at least two laser devices and a workstation with a laser processing head which can be operated safely. A first light guide leads from the first laser device to a first connection element, associated with which is a first communication connection element connected to the laser controller of the first laser device. A second light guide leads from the second laser device to a second connection element, associated with which is a second communication connection element connected to the laser controller of the second laser device. The laser processing head can be connected to one of the connection elements by a mating connection part. A safety circuit of the workstation ensures that each laser controller releases the shutter switch only if the safety circuit is connected to the communication connection element connected to the respective laser controller.Type: GrantFiled: April 11, 2001Date of Patent: July 20, 2004Assignee: TRUMPF Laser GmbH + Co.
