Welding of transparent material in electronic devices. An electronic device may include an enclosure having at least one aperture formed through a portion of the enclosure. The electronic device may also include a component positioned within the aperture formed through the portion of the enclosure. The component may be laser welded to the aperture formed through the enclosure. Additionally, the component may include transparent material. A method for securing a component within an electronic device may include providing an electronic device enclosure including at least one aperture, and positioning a component within the aperture formed through the enclosure. The component positioned within the aperture may include a transparent material. The method may also include welding the component to the electronic device enclosure.

Method of manufacture of an automotive light comprising the steps of providing a container body delimited by a first perimetral profile, providing a lenticular body, internally delimited by a second perimetral profile and externally by an outer edge corresponding to said second perimetral profile, wherein the container body acts as an absorbent element of the light beam and the lenticular body acts as a transmission element of the light beam, providing optical devices for changing the divergence of the portions of laser beams in output from the fibers, so as to collimate them overall along at least one predetermined optical axis. The method further comprises the steps of directing on a critical portion of the welding interface at least a first laser beam emitted by a respective fiber lying on an optical plane incident with said critical portion of the welding interface.

A first resin member including a first contact surface and formed of laser beam-transmissive resin and a second resin member including a second contact surface, which contacts the first contact surface, and formed of laser beam-absorbing resin are arranged one upon the other. A laser welding apparatus includes a clamping unit abutting the second resin member and applying clamping force to the second resin member, a laser emitter emitting laser beam, a laser controller controlling output of the laser beam, a displacement sensor measuring displacement of the second contact surface in stacking direction of the resin members, and a control unit controlling the clamping unit to adjust the clamping force corresponding to displacement amount of the second contact surface continuously or intermittently obtained from the displacement sensor.

A stretch-blown plastic container, includes a container body which encloses a filling volume with a container bottom; a container neck which adjoins an opposite end of the container body, having a container opening and an integrated handle region, the handle region being hollow and joined to the filling volume which is enclosed by the container body; and between the handle region and the container body, a through opening recessed and bordered over its entire periphery by wall parts of the container body and of the handle region which have been welded to one another.

A first plastic part is fixtured in a first fixture, and a second plastic part is fixtured in a second fixture for welding to each other. The first plastic part can be independently moved relative to the second plastic part in each of three directions: 1) linearly in a direction parallel with a z-axis, 2) linearly in a direction parallel with an x-axis, and 3) circularly in a circular arc about an axis parallel with a y-axis.

A first resin member including a first contact surface and formed of laser beam-transmissive resin and a second resin member including a second contact surface, which contacts the first contact surface, and formed of laser beam-absorbing resin are arranged one upon the other. A laser welding apparatus includes a clamping unit abutting the second resin member and applying clamping force to the second resin member, a laser emitter emitting laser beam, a laser controller controlling output of the laser beam, a displacement sensor measuring displacement of the second contact surface in stacking direction of the resin members, and a control unit controlling the clamping unit to adjust the clamping force corresponding to displacement amount of the second contact surface continuously or intermittently obtained from the displacement sensor.

An optical head for a laser transmission welding apparatus comprising a housing with an end on the outlet side with respect to a laser beam and a ball mounted in the housing. The ball may comprise a material whose refractive index is higher than the refractive index of quartz glass.

A binding machine comprising: —a feeding device for feeding a binding element (3) in the form of a wire or strap around one or more objects and subsequently retracting the binding element to draw it tightly around said objects; and —a laser welding device (12) for forming a welded joint between a first section at the leading end of the binding element and an adjoining second section at the trailing end of the part (3a) of the binding element fed around said objects to thereby secure this part of the binding element in a loop around the objects. The laser welding device directs a laser beam onto an area (30) at the trailing end of said second section in order to reduce the tensile strength of the binding element, wherein the feeding device retracts the binding element in order to subject this area to tensile stress and thereby cause the binding element to be broken off.

A waveguide segment with two sub-segments including a first sub-segment with a first wall and a second wall, each having an inner face by which laser light can be reflected. The inner faces are opposite to each other and a depth of the sub-segment is defined by a distance between the first and the second inner face. Further, each wall has an exit side, and an opposite entry side, a height defined by the distance between the exit and the entry side and a width. At least part of the entry side of each wall extends in an angle to the height, for which applies: 0°<α<90°. The second sub-segment may be formed complementary and the second sub-segment has a portion at the exit side of each wall. Laser light passing through the second sub-segment enters the first sub-segment between the first and the second portion.

The present invention relates to a method of manufacturing a heterogeneous material joined body.
