An ultrasonic bonding device includes a processing member, a biasing member, a first moving unit and a second moving unit. The biasing member biases a pair of separators to the ultrasonic horn. A first moving unit separates the ultrasonic horn and the biasing member from each other with respect to a transport path of the separators. A second moving unit moves the separators and positions a bonding portion of the separators between the ultrasonic horn and the biasing member. The first moving unit has a coupling cam rotationally driven by a driving unit, a first connecting portion coupling the coupling cam and the processing member, and a second connecting portion coupling the coupling cam and the biasing member, and separating the processing member and the biasing member from each other with respect to the transport path by rotation of the coupling cam.

The invention relates to a connection comprising at least two components having the following features: a first component and a second component, of which at least the second component comprises reinforced plastic, a self-piercing connection element (30) having a head and a shaft, the head thereof being supported on the first component and the shaft thereof running completely through the first and the second component, and a disc-shaped counter bearing to which the shaft is fastened such that the at least two components are fastened between the head and the counter bearing. The invention further relates to a method for the production of said connection.

The present disclosure relates to methods by which a warped workpiece is reconfigured in a pre-determined manner to reduce a separation between the warped workpiece and a joining workpiece. The warped workpiece is reformed/reshaped, prior to joining, by softening material of the warped workpiece through application of a predetermined amount of energy at or near warping and using a directional force applied to a first surface of the warped workpiece, thus reducing a separation space at a joining interface of the warped workpiece and joining workpiece.

An ultrasonic module for use in package sealing systems that includes a moveable front jaw; an elognated sonotrode disposed within the front jaw, wherein the sonotrode includes an elongated sealing face, and wherein the width of the sealing face is at least 12 inches (30.48 cm); a moveable rear jaw; and an anvil mounted on the rear jaw opposite the sonotrode, wherein the anvil mechanically cooperates with the sonotrode to seal a package.

A sonotrode that includes a sealing face; a front quarter wavelength region adjacent to the sealing face, wherein the front quarter wavelength region has been modified to increase the gain of the sonotrode; and a rear quarter wavelength region adjacent to the front quarter wavelength region, wherein the rear quarter wavelength region has been modified to create a non-uniform amplitude profile across the length of the sealing face of the sonotrode.

The invention relates to a sealing body, where heat-producing elements of a heating element are contacted from the rear side thereof. Other aspects relate to a sealing body where the site of the heat production and the site of the heat dissipation (i.e. the point of action) are as close to each other as possible. Other aspects relate to a sealing body comprising a heat element with a built-in temperature sensor. Other aspects relate to a sealing body with a defined sealing contour. Other aspects relate to a sealing body having a three-dimensionally structured contact surface. Other aspects relate to a sealing body with a circular, annular, or strip-type heat element. Other aspects relate to a sealing body with built-in electronic circuits. Other aspects relate to a sealing body that can cool the heating element as required. Other aspects relate to a sealing body that can suck up the material to be welded.

An apparatus for bonding separators in electrical devices the separators to each other so as to sandwich an electrode, includes a transmission unit configured to generate ultrasonic oscillations, an amplifier unit configured to amplify the generated oscillations, an abutting part configured to apply the amplified oscillations to the separators so as to bond the separators to each other, and separator conveyance units configured to convey the separators to a bonding position where the abutting part bonds the pair of separators to each other, the transmission unit, the amplifier unit, and the abutting part are laid out parallel to a direction in which the separators are conveyed.
