    Abstract: A robot includes a power bus assembly configured to receive a voltage and a continuous dock. The robot also includes a microcontroller in communication with the power bus assembly and the continuous dock. The microcontroller is configured to determine that the continuous dock is in contact with a surface that results in a voltage differential between the continuous dock and the surface. The microcontroller is also configured to activate a motor to apply a force that presses the continuous dock against the surface. The voltage causes a current to flow from the continuous dock to the surface such that a portion of the continuous dock melts and forms a bond to the surface.

    Abstract: Laser lift off systems and methods overlap irradiation zones to provide multiple pulses of laser irradiation per location at the interface between layers of material to be separated. To overlap irradiation zones, the laser lift off systems and methods provide stepwise relative movement between a pulsed laser beam and a workpiece. The laser irradiation may be provided by a non-homogeneous laser beam with a smooth spatial distribution of energy across the beam profile. The pulses of laser irradiation from the non-homogenous beam may irradiate the overlapping irradiation zones such that each of the locations at the interface is exposed to different portions of the non-homogeneous beam for each of the multiple pulses of the laser irradiation, thereby resulting in self-homogenization. Thus, the number of the multiple pulses of laser irradiation per location is generally sufficient to provide the self-homogenization and to separate the layers of material.

  • Publication number: 20130299097
    Abstract: The present disclosure generally describes techniques suitable for use in the construction or recycling of composite materials, such as thermoplastics. A coated thermoplastic article may comprise a thermoplastic portion coupled to a supramolecular polymer interface layer, with a coating layer applied to a surface of the supramolecular polymer interface layer. Application of heat to the coated thermoplastic article may cause the supramolecular polymer interface layer to undergo a phase change, allowing the coating layer to be removed from the thermoplastic portion. Application of force to the coated thermoplastic article may enhance the removal of the coating layer. Embodiments of methods, compositions, articles and/or systems may be disclosed and claimed.

  • Publication number: 20130276991
    Abstract: A method for disconnecting a first mechanical part from a second magnetic mechanical part, the first mechanical part being adhered to the second magnetic mechanical part by an adhesive film along a connecting area. In the method, a magnetic field is generated at least within the connecting area so as to generate, by induction, eddy currents in the second magnetic mechanical part, to soften the adhesive film and enable disconnection of the first and second mechanical parts.

  • Publication number: 20130199732
    Abstract: The present invention provides a method of stripping multiple plies of a pressure-sensitive adhesive layer, capable of easily separating and dismantling the joint portion in a short time, without affecting the adherend involved. The stripping method of the present invention strips the multiple plies of a pressure-sensitive adhesive layer, including a pressure-sensitive adhesive body having at least a pressure-sensitive adhesive layer containing heat-expandable fine particles and an adherend, the pressure-sensitive adhesive body and the adherend being laminated on each other, and the multiple plies of a pressure-sensitive adhesive layer contain a coloring matter component, and the pressure-sensitive adhesive body and the adherend are stripped from each other, by irradiating the coloring matter with a laser light beam having a wavelength coinciding with the absorption wavelength of the coloring matter and by expanding the heat-expandable fine particles with the aid of the heat thus generated.

  • Publication number: 20130180665
    Abstract: A method of cutting an article (172) from a chemically strengthened glass substrate (110) includes generating a pulsed laser beam (108) from a laser source (106). The pulsed laser beam (108) may have a pulse duration of less than about 1000 fs and an output wavelength such that the chemically strengthened glass substrate (110) is substantially transparent to the pulsed laser beam (108). The pulsed laser beam (108) may be focused to form a beam waist (109) that is positioned in the same horizontal plane as an inner tensile region (124) of the chemically strengthened glass substrate (110). The beam waist (109) may be translated in a first pass along a cut line (116), wherein the beam waist (109) traverses an edge (111) of the chemically strengthened glass substrate. The beam waist (113) may then be translated in a second pass along the cut line (116) such that a crack (119) propagates from the edge (113) along the cut line (116) ahead of the translated beam waist (109) during the second pass.
