20160116355 | METHOD FOR DETERMINING THE COMPRESSION LEVEL OF A NODE AFTER ULTRASONIC WELDING - A method for determining the compression level of a node by compacting and welding electrical lines inserted into a compression chamber of an ultrasonic welding system, the compression chamber having an adjustable height and width. The method includes inserting the lines into the compression chamber, compacting the lines, determining the compacting cross section of the compacted lines, determining the actual total cross section via a correlation function taking the compacting cross section into account, welding the compacted node with a welding parameter set, determining the welding dimension from the height (h | 04-28-2016 |
20130062397 | METHOD FOR WELDING TOGETHER TWO PLANAR COMPONENTS - A method for welding together at least two planar metal components oriented with respect to one another using ultrasound, wherein for the welding operation the components are arranged between a tool transmitting ultrasonic vibrations and a counter-holder and fixed between same by the application of pressure. In order for the components to have a desired orientation with respect to one another after the welding operation that corresponds to the orientation prior to the welding operation, according to the invention the components, prior to applying the ultrasonic vibrations for welding the same together, are deformed by means of at least one projection that projects from the tool and/or the counter-holder beyond the respective working surface using the application of force such that a translatable and rotatable relative movement is suppressed, or substantially suppressed, between the components and that the welding operation is carried out after the deformation. | 03-14-2013 |
20120298645 | METHOD AND ASSEMBLY FOR THE ELECTRICALLY CONDUCTIVE CONNECTION OF WIRES - A method and assembly for the electrically conductive connection of a bundle of wires having an insulation, wherein the insulation is at least partially removed by means of ultrasonic effects. In order to ensure high mechanical strength in a good electrically conductive connection, according to the invention the insulation of the wires is removed in a first step by means of plastic-ultrasonic welding and the wires are bonded in a second step by means of metal-ultrasonic welding or resistance welding. | 11-29-2012 |
20120125976 | PROCESS FOR REDUCING ALUMINIUM PICK-UP, AND ULTRASONIC WELDING DEVICE - A process for reducing aluminum pick-up and adherence during the ultrasonic welding of aluminum braids which are welded in a vertically and/or horizontally adjustable compression chamber of an ultrasonic welding device. The static tool parts which delimit the compression chamber have working surfaces made from polycrystalline diamond (PCD). | 05-24-2012 |
20100170935 | METHOD FOR CONNECTING STRANDED WIRES IN AN ELECTRICALLY CONDUCTING MANNER AND ULTRASOUND WELDING DEVICE - An ultrasound welding device and a method for connecting stranded wires in an electrically conducting manner with a metal U-shaped support by ultrasound welding, where the stranded wires are made of individual wires that are essentially aluminum. The sonotrode used according to the invention is a sonotrode has a welding surface which is shaped like an open trapezoid having short base sides as the bottom face during welding, the stranded wires directly contacting the bottom face and the lateral faces that extend therefrom and form an obtuse angle. The overall cross-sectional area F | 07-08-2010 |
20090314412 | QUALITY CONTROL METHOD FOR ULTRASOUND WELDING - A quality control method for ultrasound welding. The method provides for the generation of a tolerance range which is adjusted to the progress of the welding process and which is generated from measured values which influence the welding process. A measured value tolerance range is determined from measured values of executed welding processes, the measured values being associated with at least one parameter which influences the welding process and/or represents the goods of the welding process. Measured values are associated with an identical parameter of a further welding process following thereafter and are considered during the quality monitoring in such a way that the measured value tolerance range is changed in its form or composition to an average value for further welding processes, in accordance with the variance between the additional measured values and the tolerance range determined from previous measured values. | 12-24-2009 |
