Abstract:
A ultrasonic processing apparatus, comprising:a rotatable, ultrasonic horn member having a first axial side and a second axial side; a first, rotatable axle member which is operatively joined to said first axial side of said horn member; a first isolation member which is operatively joined to said first axle member, said first isolation member capable of bending under a horn-life range of sonic frequencies to provide an operative component of motion along a radial direction of the first isolation member and an operative component of motion along an axial direction of the first isolation member; a first coupler which connects between said first isolation member and a first, fixedly mounted rotational bearing, said first coupler operatively secured to said first isolation member; a second, rotatable axle member which is operatively joined to said second axial side of said horn member; a second isolation member which is operatively joined to said second axle member, said second isolation member capable of bending under a horn-life range of sonic frequencies to provide an operative component of motion along a radial direction of the second isolation member and an operative component of motion along an axial direction of the second isolation member; a second coupler which connects between said second isolation member and a second, fixedly mounted rotational bearing, said second coupler operatively secured to said second isolation member; a rotatable anvil member which is cooperatively positioned to provide a selected horn-anvil gap distance between said anvil member and said horn member, said anvil member located in a horizontally offset and vertically overlapping arrangement relative to said horn member; an ultrasonic exciter which is operatively connected to said horn member and can provide an operative amount of ultrasonic; and an actuator which can selectively adjust said horn-anvil gap distance.
