A system for separating the front and back outer glass layer from the casing/body of electronic mobile devices and for cutting mobile device screen protector sheets by way of laser burning and cutting comprises a housing, such housing containing a laser; a mirror galvanometer; a safety chamber enclosure; a metal plate with internal glass sheet; a chamber with opening and closing lid, lid button and lid sensor; a control printed circuit board with processor; a power inlet; a power supply; and an on/off switch.

A device for marking a component. The device includes a laser device for generating a laser marking beam, a support surface for providing the component to be marked, and a housing for housing a working region between the laser device and the component to be marked. The housing has a multi-part design, and the housing includes at least a first housing part and a second housing part. The two housing parts are designed to be movable relative to each other and are arranged such that in a loading position, the housing provides an open working region, by means of which the component to be marked can be introduced into the working region, and in a working position, the housing completely closes the working region.

Provided is a method for refining magnetic domains of grain-oriented electrical steel plates including: a steel plate supporting roll position adjusting step of controlling a vertical direction position of the steel plate while supporting the steel plate; a laser radiating step of melting the steel plate by radiating a laser beam to form grooves on the surface of the steel plate; and a setting and maintaining step of setting and maintaining an internal operation environment of a laser room in which the laser radiation is performed, so as to increase magnetic domain refinement efficiency and improve workability by optimizing equipment and processes, thereby increasing the processing capacity.

A laser marker includes a laser light source; a scanner configured to scan laser light, from the laser light source, outward; a first housing accommodating the laser light source; a second housing accommodating the scanner, the second housing being rotatable with respect to the first housing; a sensor configured to output a detection signal; and a controller configured to: based on receiving the detection signal indicating that the rotation position of the second housing is either in a first or second rotation position from the sensor, control the laser light source to emit the laser light outward; and based on receiving the detection signal, not indicating that the rotation position of the second housing is either in the first or second rotation position, control the laser light source not to emit the laser light outward.

A galvano scanner that irradiates an object with a laser beam to perform machining, the galvano scanner comprising: an emission unit that emits the laser beam; a protective glass that protects the emission unit from a scattered matter generated in machining; and a glass holding mechanism that holds the protective glass, the protective glass at least including a triple structure in a vertical direction, the glass holding mechanism holding the protective glass that is the lowermost layer in the protective glass having the triple structure so that the protective glass that is the lowermost layer can be fallen off downward.

An improved laser apparatus, inscribed in a parallelepiped rectangle R defined by a longitudinal axis, X, a vertical axis, Y defining a plane P and a lateral axis, Z, including a mounting means to mount the laser apparatus on a window, preferably a multi-glazed window, mounted in situ. The laser apparatus also includes a laser device generating a laser beam to treat a surface of the window, an orientation means able to orientate the laser beam defining a maximum decoatable surface WSm on the coated surface and a housing including an aperture to let the laser beam going out of the housing. The laser apparatus includes a skirt at least partially surrounding the aperture where the skirt is opaque to the laser beam. A related method is also described.

A laser shielding device interposed between the camera and the reflected light and is provided with a plurality of plates juxtaposed at an interval. Of the plurality of plates, an incident-side plate disposed on an incident side of the reflected light may be made larger in heat capacity compared to other plates disposed on the camera side of the incident-side plate.

A beam homogenizer for surface modification comprises: a first lens array configured to split a laser beam, irradiated from a laser beam irradiation unit, into a plurality of beamlets; a second lens array configured to transmit the plurality of beamlets and comprising a plurality of lenslets corresponding to the first lens array; and a focusing lens configured to focus the plurality of beamlets, transmitted through the second lens array, onto a surface of a target. The beam homogenizer further comprises: a plasma generation-preventing unit disposed between the first and second lens arrays and configured to prevent plasma from being generated in the focal zone of the beamlets; or a damage-preventing unit disposed between the focusing lens and the target and configured to prevent the focusing lens from being damaged by energy generated when the plurality of beamlets is irradiated onto the target.

A laser processing machine has a processing area and a laser processing device. A workpiece can be processed by the laser processing device at a processing location via emission of laser radiation to generate a processing product. An environment of the processing area is shielded against the laser radiation by a protective housing. The processing product can be moved in a discharge direction to pass a boundary of the protective housing that is flexible in the discharge direction. A product rest, arranged below the processing location in the vertical direction and extending in the discharge direction, functions to store the processing product. In the vertical direction below the processing location, the protective housing extends in the discharge direction, forming an extension with which the protective housing extends over the product rest. The boundary limits the extension in the discharge direction and is arranged above the product rest.

A weld is formed in a workpiece such as a pipeline by first activating a melting device, such as a laser, to form a molten weld pool in the workpiece and then activating a welding device, such as a GMAW torch, to initiate a weld in the weld pool. The weld therefore incorporates the weld pool homogeneously. Relative movement between the activated welding device and the workpiece continues and completes the weld while the melting device remains deactivated.
