Patent number: 8653406Abstract: A device and a process for processing and/or joining work pieces via laser radiation, with an effective power laser and a pilot target laser that emit laser beams of different wavelengths, with the laser beams being directed at the work pieces by laser optics. Regarding the laser beams, by the laser optics that comprise at least one diffractive optical element (DOE) as a masking system, the beam pattern of the pilot target laser is adjusted to match the beam pattern of the effective laser beam. This is accomplished preferably by removing the pilot laser beam from the effective laser beam for part of the path length by dichroic mirrors, and by expanding the diverging pilot laser beam on said part of the path length by deflecting mirrors whose distance from the dichroic mirrors is variable.Type: GrantFiled: May 1, 2009Date of Patent: February 18, 2014Assignee: Leister Technologies AGInventors: Ulrich Gubler, Michael Scheidt

Patent number: 8505604Abstract: The invention relates to a laser head (11) for connecting tubular parts (1, 3, 12, 13) by the laser transmission method and to a method of connecting the tubular parts (1, 3, 12, 13) by means of the laser head (11). The laser head (11) and the method that can be performed by the laser head (11) are suitable in particular for connecting a connecting element or branching element (1) to one end of a plastic pipe (3). The laser head (11) makes simultaneous welding possible and has at least two shell parts (16) that can be radially separated from each other so that the laser head (11) can be placed around a connecting section (4) or a connecting region (15) of the tubular parts (1, 3, 12, 13). A number of laser sources (17) are arranged in the shell parts (16) in such a way that the laser beams (7) emerging from the laser sources (17) overlap at the connecting section (4) or at the connecting region (15) of the parts (1, 3, 12, 13).Type: GrantFiled: August 20, 2009Date of Patent: August 13, 2013Assignee: LEISTER Technologies AGInventors: Erich Stauffer, Pius Barmet, Oliver Hinz, Michael Scheidt, Ulrich Gubler

Patent number: 8084709Abstract: The invention concerns a laser device for joining work pieces made of plastic by means of beam welding technology, with a processing head that has focusing devices for the laser beam. Here, the focusing device that is closest to the work pieces has a rotatably supported cylinder lens in the shape of a roller that focuses the laser beam along a single axis and presses the work pieces together in the form of a line in an area around the impact point of the laser beam. In order to enable the cylinder lens to always contact the surface of the work piece facing the processing head in a precisely tangential manner, the processing head has a pendulum-type suspension for the rotatable cylinder lens. This also makes it possible for the contact pressure exerted by the processing head to always act perpendicularly on the work pieces so that they are pressed together in all welding places in the same way in a defined manner during the welding process.Type: GrantFiled: May 5, 2009Date of Patent: December 27, 2011Assignee: LEISTER Process TechnologiesInventors: Michael Scheidt, Oliver Hinz, Daniel Vogler, Adolf Niederberger
