Publication number: 20200198254Abstract: Sensors incorporated within a waveguide detect a laser light output from at least a laser delivery optical fiber to provide in situ feedback of the laser light intensity detected by the sensor. The sensors may detect laser light directly from the laser delivery optical fiber or as reflected back from a plurality of work pieces during a weld cycle. In various aspects, the feedback provided from the sensors is used to control the laser light intensity or to alert an operator that the laser light intensity is below a predetermined parameter.Type: ApplicationFiled: May 23, 2018Publication date: June 25, 2020Applicant: Branson Ultrasonics CorporationInventors: Scott CALDWELL, Sean TRIMBY, Raul PASOLS

Publication number: 20200198255Abstract: A connecting arrangement includes a first plastic component, a second plastic component, and a closed induction ring that is arranged between the first and second plastic components in a joining gap that is partially filled with molten plastic. The first plastic component has a first joining region that is configured as a stepped receiving opening with a first joining contour. The second plastic component has a second joining region that is configured as a stepped shoulder with a second joining contour. The second joining region is inserted into the first joining region to form the joining gap. The first and second joining contours are adapted to one another so as to center the first joining region, the second joining region, and the induction ring in the joining gap with respect to one another. A method in one embodiment includes welding the first and second plastic components of the connecting arrangement.Type: ApplicationFiled: June 14, 2018Publication date: June 25, 2020Inventors: Frederic Cousin, Werner Steinberger

Publication number: 20200198257Abstract: A lubricant/sealer dispenser is disclosed for a component press-in system that includes a pressurized lubricant/sealer reservoir filled with lubricant/sealer. A nozzle is supplied with lubricant/sealer from the reservoir and includes an offset tip formed of PTFE that is enclosed in a steel tube. A controller controls a motor that rotates the nozzle within an opening in a part at a selected depth. The motor rotates the nozzle about a fixed axis and follows an inner surface of the opening as the part is moved by a robot relative to the nozzle in a selected pattern. The nozzle applies the lubricant/sealer by applying the lubricant/sealer onto the inner surface of the opening.Type: ApplicationFiled: March 2, 2020Publication date: June 25, 2020Inventors: Alexander MARROCCO, Hossein FIROOZGAN, Joosok JINN, Isaac ZOLOTAREV, Arnold BELL

ELECTROMAGNETIC INDUCTION WELDING DEVICE FOR JOINING COMPOSITE MATERIALS AND RELATIVE JOINING METHOD
Publication number: 20200198258Abstract: A portable welding device comprising: a base facing a work surface, designed to receive tapes in electrically conductive composite materials to be joined or defined by at least one already positioned tape; an operating head receiving one tape at a time and movable with respect to the base along at least a first movement line parallel to the work surface; a motorized arm connecting the operating head to the base and selectively activatable to impart movements to the operating head; and feeding means selectively activatable to feed one tape at a time to the operating head and connected to the operating head; the operating head comprises a positioning roller receiving a tape at a time; a pressure roller spaced from and aligned with the positioning roller along the first movement line; and an inductor interposed between the positioning roller and the pressure roller with reference to the first movement line.Type: ApplicationFiled: December 18, 2019Publication date: June 25, 2020Inventors: Nicola GALLO, Stefano Giuseppe CORVAGLIA, Silvio PAPPADA -
Publication number: 20200198259Abstract: A transverse cutting system for a machine for the production of plastic film includes a supporting structure carrying a cutting unit, which are moved between a rest position away from a path of a plastic film being wound and an operating position along the path of the plastic film; a rotating support carrying a hot wire; a rotating cap, associated to an idle roller and arranged transversally to the path of the plastic film that is moving forwards, and an actuator, which controls the rotation of the rotating support carrying the rotating cap and causes the rotating cap to interfere with the plastic film before the hot wire also interferes with said plastic film. The same plastic film, owing to the friction force generated by the rotating cap, entrains it with it, causing the rotating cap to equalize the linear velocity of the plastic film.Type: ApplicationFiled: June 11, 2018Publication date: June 25, 2020Inventor: Nicola Lombardini
