| 20120085740 | DEVICE FOR SIMULTANEOUSLY PROCESSING THE CIRCUMFERENCE OF A WORKPIECE WITH LASER BEAMS - A device for simultaneously processing a circumference of a workpiece includes a plurality of laser-lens modules and a waveguide. The modules each include a diode laser and a lens system and is configured to emit a laser beam radially in a shared radiation plane. The waveguide includes a lower part and an upper part that together form a cavity enclosing the radiation plane. The laser-lens modules are configured so that the laser is reflected repeatedly between a bottom surface and a cover surface and propagates in an unaffected manner within the radiation plane so as to form a beam spot that strikes the workpiece with a homogeneous energy distribution. The beam spot has a height based on a distance between the surfaces and a width based on a divergence angle in the radiation plane and a distance of the module from the workpiece surface. | 04-12-2012 |
| 20110100963 | DEVICE FOR THE LASER TRANSMISSION WELDING OF COMPONENTS OVER A RING-SHAPED CONTACT ZONE - A device for joining by a laser beam two components along a ring-shaped contact zone jointly formed by the components using a laser beam where a first of the two components is transmissive for the laser beam and a second of the two components is absorptive for the laser beam. The device includes a receptacle configured to affix the absorptive component and an internal clamping chuck with at least one contact surface configured for placement on the transmissive component within a free inside area of the contact zone. The device also includes a pressure element with a free inside area that is larger than an extension of the contact zone, a laser source configured to emit the laser beam, a beam guide unit, a beam guide control unit, an external axial bearing, a rotatable holding wheel, and an internal axial bearing. The pressure element is connected to the internal clamping chuck via the external axial bearing, the holding wheel and the internal axial bearing so as to transmit to the internal clamping chuck contact pressure exerted on the pressure element. | 05-05-2011 |
