摘要:
A sealing tool (100) includes an anvil (102) and a horn (106), at least one of which includes a sealing surface (104) having a gusset sealing section (112) and a zipper sealing section (114), each configured differently than the other. The gusset sealing section (112) includes a plurality of sealing beads (120, 122) including a gusset section barrier sealing bead (120) having a first height and a protective sealing bead (122) having a second height, the second height being smaller than the first height. The zipper sealing section (114) includes a zipper section barrier sealing bead (124) extending and a tapered section (126) adjacent to the zipper section sealing bead (124), the tapered section (126) tapering from a larger height adjacent to the zipper section sealing bead (124) to a smaller height as a distance away from the zipper section sealing bead (124) increases.
摘要:
An ultrasonic sealing tool including an anvil with a sealing surface, a horn with a sealing surface facing the sealing surface of the anvil, the sealing surface of the anvil including a plurality of beads including a first bead having a first height and at least one second bead having a second height, the second height being less than the first height, the ultrasonic sealing tool delivering ultrasonic vibrations via at least one of the anvil and the horn to create a closure seal in a work piece positioned between the anvil and the horn, the closure seal including a first seal created by the first bead and at least one second seal created by the at least one second bead, the first seal having a weld depth greater than a weld depth of the at least one second seal.
摘要:
A multi -element ultrasonic atomizer (10) and method for atomizing liquids is described, having a power generator, a converter (11), an ultrasonic horn (12) coupled to the converter (11), and at least two atomizing probes (16) coupled to the ultrasound horn (12), each atomizing probe (16) including at least one liquid passage (17) extending longitudinally along the atomizing probe (16) and terminating at an atomizing tip at a distal end of the atomizing probe (16). The atomizing probes (16) are made to vibrate at same frequency A liquid is delivered to an atomizing surface through the liquid passage and through an opening at the atomizing tip.

An ultrasonic sealing device (100), including a horn (112) having a sealing surface, an anvil (114) having a sealing surface, at least one of the horn (112) and the anvil (114) being moveable to engage the respective sealing surfaces, the sealing surfaces of the horn (112) and the anvil (114) including a plurality of protrusions (302) and a recess between each of the protrusions (302), each of the protrusions (302) having a distal surface (322) and sloped sidewalls with curved edges therebetween and each of the recesses including a recess surface (320) with curved edges, wherein, upon engagement of the sealing surface of the horn (112) with the sealing surface of the anvil (114), the distal surfaces (322) of each of the protrusions on each of the sealing surfaces engage corresponding ones of the recess surfaces (320) of each of the recesses on each of the sealing surfaces and define gaps (330) between the sidewalls of each adjacent protrusion.
摘要:
An energy controller (36) is described for a vibration welder (10) wherein the energy imparted into work-pieces (16, 18) being vibration welded is derived and compared with an energy set point to control the vibration welding operation. After a vibration welding operation has encountered the energy set point the welding operation is stopped and the quality of a weld derived from a comparison with another parameter associated with the vibration welding. The other parameter can be the amount of movement of one of the work-pieces during vibration welding or the time involved to inject the energy into the work-pieces to achieve the vibration weld.
摘要:
A system and method for ultrasonic sample preparation, includes a vessel having a wall defining an inner volume. An ultrasonic probe is disposed in the inner volume of the vessel. A microplate having a plurality of sample wells is also disposed in the inner volume of the vessel. An actuator is connected to the microplate and is configured to move the microplate relative to the ultrasonic probe in the inner volume to facilitate uniform distribution of ultrasonic energy.
