  • Publication number: 20180141157
    Abstract: A baffled optical waveguide has a body shaped to partially or wholly surround a part or parts being processed by being illuminated with light. The body has optical baffles therein that define light channels through which the light travels as it transits the baffled optical waveguide. Outlets of the light channels are adjacent an opening in the body which receives an area or areas of the parts or parts being processed. Each light channel homogenizes the light as it transits through that light channel. The optical baffles that define the light channels keep light from diverging in the baffled optical waveguide as it transits through the light channels. In an aspect, a part (or parts) is processed by illuminating it with light via the baffled optical waveguide.

  • Publication number: 20180120148
    Abstract: A broken piezoelectric material in an ultrasonic transducer of an ultrasonic stack of an ultrasonic device is detected by measuring a test piezo coupling constant with a test scan of the ultrasonic stack. The test piezo coupling constant is compared to a previously measured baseline piezo coupling constant. The piezoelectric material is determined to be broken when the test piezo coupling constant is less than the baseline piezo coupling constant by more than a predetermined amount.

  • Publication number: 20180021879
    Abstract: A copper or aluminum tube is cut and sealed in an ultrasonic tube sealer. A section of the tube is placed laterally in a V-shaped recess of a center member of a forming tool of an anvil of the ultrasonic tube sealer. The anvil and a horn tip are brought together with the center member received in a channel of a forming tool of the horn tip to cut the tube with the cut tube having cut ends on opposed sides of the center member. At least one of the cut ends is pinched together between the forming tool of the anvil and the forming tool of the ultrasonic horn tip and the ultrasonic horn is ultrasonically vibrated to ultrasonically weld the at least one cut end together to seal that cut end.

  • Publication number: 20150007704
    Abstract: An ultrasonic tuned blade includes a base and a tire cutting edge made of a tool steel having a vanadium content which is at least about 8 percent. For example, the tool steel can have a combined vanadium, cobalt, and tungsten content that is at least about 15 percent. The tool steel can be formed into a simple block via a powder metallurgy process. The simple block can be milled into an ultrasonic tire cutting horn shape comprising a tuned blade including a base and a tire cutting edge. The ultrasonic steel tire cutting horn can be heat treated to provide the tool steel with a Rockwell hardness, for example, of at least about 50 HRC and less than about 64 HRC. The ultrasonic steel tire cutting horn can include a low friction or wear resistant coating.

  • Patent number: 8925612
    Abstract: An ultrasonic collet horn for an ultrasonic welder has a body and a collet over which a replaceable horn tip is receivable. The collet has a plurality of axial slits therein that divide the collet into sections and a tapered axially extending bore that tapers outwardly as it extends axially outwardly. The body has a threaded bore that is threadably engageable with a threaded inner section of a collet lock. The sections of the collet are forced outwardly against an inner wall of the horn tip when the horn tip is received on the collet and the collet lock tightened into the threaded bore to secure the horn tip on the collet.

  • Publication number: 20140374466
    Abstract: Multi-stranded wires are clamped between an ultrasonic welding tip and an opposing anvil. The multi-stranded wires are made of a material that is more malleable than copper, or of a material that has a malleability that is substantially the same or greater than the malleability of aluminum. The plurality of multi-stranded wires can be clamped between opposing side surfaces to further form the wire bundle. Ultrasonic energy is applied to a first side of the wire bundle adjacent the ultrasonic welding tip. After termination of ultrasonic energy to the first side, the wire bundle is rotated 180 degrees relative to the anvil and ultrasonic energy is applied to a second side of the wire bundle, wherein the second side is oppositely disposed relative to the first side.

  • Patent number: 8343299
    Abstract: Unabsorbed infrared laser light that has passed though plastic parts to be welded with a low absorption TTIr process is recirculated in an infinite loop back to the low absorption weld interface for reabsorption in the process. On each pass in the infinite loop, more infrared laser light is absorbed at the weld interface.

  • Publication number: 20120181250
    Abstract: A method of using TTIr welding to weld together two high transmissivity plastic parts includes providing one or both parts with a modified surface that increases that plastic part's absorbtivity to laser light. The two parts are then laser welded by directing a beam of infrared laser light to the parts which are oriented so that the beam of infrared laser light first passes through one of the parts, impinges the modified surface (or surfaces) at a weld interface where the two plastic parts abut each other to melt the plastic parts at the weld interface, and then passes through the other plastic part.
