  • Patent number: 10814432
    Abstract: In the method according to the disclosure for the unloading of a workpiece part from a workpiece, in parallel with processing time, by means of an unloading element, e.g. a vacuum sucker, the workpiece part is cut from an especially plate-form workpiece by means of a laser beam. The movement of the laser beam relative to the workpiece at least along a first movement axis (X) is divided into a movement of the workpiece and a movement of the laser beam. Before executing a final cut, which separates the workpiece part from the workpiece, the workpiece is decelerated until standstill and the final cut is then executed for example, by moving the laser beam. The workpiece part is being unloaded by an unloading element that operates at least partially during cutting of the workpiece. The unloading element operates according to one of three operating options.

    Abstract: Optical elements with small increments in average density are formed in a substrate by laser micromachining using a variable aperture and a pattern mask set of pattern masks each having of shape-defining elements whose density differs among the pattern masks in first density increments. A laser light beam passes through a combined mask formed by the variable aperture and one pattern mask selected from the pattern mask set. The variable aperture controls beam size and the pattern mask spatially modulates its intensity. A focusing element focuses light from the combined mask on a small averaging region of the substrate. Different combinations of the size of the aperture mask and the selected pattern mask are used in combination at respective averaging regions of the substrate. The resulting average densities of the optical elements vary among the averaging regions in increments that are small compared to the first density increments.

  • Patent number: 8780406
    Abstract: A visible laser beam scanned by a galvano-scanner system is aligned at each of positioning points on the top surface of a master work by manual operation to record sensor position signals of position sensors on galvano-scanners. The sensor position signals on each positioning point are recorded to create a drive pattern in accordance with recorded sensor position signals. The drive pattern no longer has optics system error sources including focus error and attachment error as well as errors caused by scale, offset and the like, also eliminating the need for entering a distance as far as the top surface of the work. Therefore, the drive pattern with error components removed can be created with ease.

  • Patent number: 8766136
    Abstract: A welding tool is configured with a housing enclosing a fiber laser system which is operative to produce a weld seam for connecting two workpieces. The fiber laser system includes a focusing optic configured to focus the output beam of the system so that it propagates through an elongated slit formed in the bottom of the housing. The fiber laser system is capable to move along a predetermined path extending parallel to the longitudinal direction of the slit and limited by the perimeter thereof. The output beam is generated only when the slit sits upon at least one of the workpieces.

  • Patent number: 8735774
    Abstract: A laser beam propagates along a beam axis for incidence on a work surface mounted on a support. The support operatively connects to a positioning system moving at least one of the laser beam and the target specimen relative to each other to position the laser beam at selected locations on the work surface. At least one force reaction compensation motor is located in a common force plane with, and as close as possible to, a corresponding stage motor. Any moment arm between the compensation motor and the corresponding stage motor is reduced or eliminated, allowing the compensation motor to directly couple and react to stage forces with virtually zero moment arm. Six degrees of freedom can be controlled with only four motors, since each compensation motor is directly coupled and aligned to a corresponding stage motor.

    Abstract: Methods and systems for forming a scribe line in a thin film stack on an inner surface of a thin film photovoltaic superstrate are provided via the use of a cleaning laser beam and a scribing laser beam. The cleaning laser beam is focused directly onto the exposed surface of the superstrate such that the cleaning laser beam removes debris from the exposed surface of the superstrate, and the scribing laser beam is focused through the exposed surface of the superstrate and onto the thin film stack such that the scribing laser beam passes through the superstrate to form a scribe within the thin film stack on the inner surface of the superstrate. The method and system can further utilize a conveyor to transport the superstrate in a machine direction to move the superstrate past the cleaning laser source and the scribing laser source.
