摘要： A method and an apparatus for ultrasonic staking a first part having a fastening portion to a second part having an opening corresponding to the fastening portion. The method comprises aligning the fastening portion of the first part with the corresponding opening in the second part, inserting a head of the fastening portion through the corresponding opening, and causing a horn of an ultrasonic staking stack to contact the head, apply ultrasonic energy oscillating at a frequency between 45 kHz and 75 kHz, and move along an axis of the fastening portion as the head melts to form a stake. The stake can include a melt-form that joins the first part and the second part to each other, and the fastening portion can have a geometry or a size disposed to flapping.

摘要： An apparatus for joining a first film portion and a second film portion together along a seal line. The apparatus includes a horn and anvil. The anvil is positioned close to the horn. The horn or anvil has a face that is rotatable about a rotation axis. The face has a raised profile, and a height thereof has a dimension corresponding to 50% to 150% of a thickness of the first film portion or the second film portion. The face is positioned such that the raised profile extends along the circumference such that continuous running contact is provided between the raised profile and the other of the one of the horn or the anvil when rotated about the rotation axis, to form the seal line without any external structure to control a distance between the horn/anvil. A tapered bonding profile, a traction pattern, and a cut-and-seal feature are also disclosed.

摘要： A system includes a first horn, a first ultrasonic transducer, a second horn, a second ultrasonic transducer, a memory, and a controller. The first horn includes a first part-interfacing surface. The second horn includes a second part-interfacing surface and is positioned relative to the first horn such that a part to be welded can be positioned between the first and second part-interface surfaces. The controller is configured to cause a first ultrasonic energy to be applied through the first horn via the first transducer to cause the first part-interfacing surface to vibrate, cause the first horn to move in a first direction at a first time, cause a second ultrasonic energy to be applied through the second horn via the second transducer to cause the second part-interfacing surface to vibrate, and cause the second horn to move in a second direction at the first time.

摘要： An ultrasonic welding system. The system includes an ultrasonic transducer assembly having a horn and a first transducer and a second transducer arranged to impart ultrasonic energy into the horn. The horn has a first part-interfacing surface and a second part-interfacing surface opposite the first part-interfacing surface. An actuator assembly is operatively coupled to the ultrasonic transducer assembly and configured to cause rotation of the horn. A controller is configured to: cause the actuator assembly to rotate the horn so that the first part-interfacing surface applies the ultrasonic energy to a first part along an entire length of the first part-interface surface while a first ultrasonic energy is applied through the horn via the first transducer to cause the first part-interfacing surface to vibrate back and forth along its entire length as the first ultrasonic energy is applied by the first transducer to the horn.

摘要： A method and system for fabricating an article using a first bonding module having a first bonding module face and a second bonding module having a second bonding module face include supplying a first non-woven fabric to at least one of the first bonding module face and the second bonding module face, and supplying a plurality of elastic strands to a surface of the first non-woven fabric. The method and system further include entrapping a first elastic strand between a first pair of adjacent bonds in a first row in the first non-woven fabric, entrapping a second elastic strand between a second pair of adjacent bonds in the first row, and creating a third pair of adjacent bonds in the first row free of elastic bands therebetween. The third pair of adjacent bonds is located between the first pair of adjacent bonds and the second pair of adjacent bonds.

摘要： A system for providing power to more than one ultrasonic welding probe from M power supplies includes N multipoint units and a base. Each of the N multipoint units includes: a housing, a plurality of analog or digital inputs configured to carry distance information regarding probe distance of a plurality of ultrasonic welding probes, a dedicated high voltage input connector connectable via a high voltage cable to a dedicated high voltage output connector of one of the M power supplies, and a microcontroller. The microcontroller is configured to: direct power from the dedicated high voltage input connector to a corresponding one of the plurality of ultrasonic welding probes, and sample the distance information of the plurality of ultrasonic welding probes at a rate of at least once per millisecond. The base houses the M power supplies, wherein M and N are both integers greater than or equal to 1.

摘要： The present disclosure can provide for an ultrasonic welding method for a pair of workpieces. The method can include first pressing an ultrasonic welding stack against a first workpiece in the pair so that the first workpiece comes into contact with a second workpiece in the pair. The method can then provide for initiating a weld phase by outputting energy from the ultrasonic welding stack to the first workpiece. The method can provide for monitoring, with at least one sensor, a sensed parameter. The sensed parameter can be, for example, weld force and/or weld force rate of change. The method can provide for determining whether the sensed parameter has reached a predetermined level. Based on determining that the sensed parameter has reached the predetermined level, the method can provide for ending the weld phase.

摘要： Device and method for laser welding around a circumference of a workpiece. A fixed, non-movable unitary optical reflector has a pair of optical reflecting surface portions on a first side surface and a second side surface, respectively, arranged at an obtuse angle relative to each other. A workpiece is fixed in an assembly having the reflector. During setup, the vertical distance is adjusted between the reflector and workpiece along an axis that is transverse to a longitudinal axis thereof without any adjustment of the reflecting surfaces. The first and second side surfaces define a curve that is transverse to the longitudinal axis. Once setup has been completed, a laser beam is directed so that it moves along the optical reflector to thereby produce a 360 degree circumferential weld around the workpiece. Another assembly is provided to change the laser beam direction multiple times to irradiate a circumference of a fixed workpiece from a fixed laser source.

摘要： An apparatus for joining a first film portion and a second film portion together along a seal line. The apparatus includes a horn and an anvil. The anvil is positionable in close proximity to the horn. Either the horn or the anvil has a face with a width dimension and a circumference and is rotatable about a rotation axis. The face has a raised profile, and a height of the raised profile has a dimension corresponding to 50% to 150% of a thickness of the first film portion or the second film portion. The face is positioned such that the raised profile extends along the circumference such that continuous running contact is provided between the raised profile and the other of the one of the horn or the anvil when rotated about the rotation axis, to form the seal line without any external structure to control a distance between the horn and the anvil.
