Ultrasonic wire bonding is a process of connecting two or more surfaces using metal wire. In battery manufacturing heavy used to connect cells with each other commonly printed circuit board (aluminum, plated bare copper) busbar by means diameters ranging 100-500 µm. Single sided cell that connections are made from one side on both positive (cap) and negative (crimp) terminals. The main advantages this method easy automation, low production time, easier recyclability, self-fusing properties...
Wire bonding is a method of connecting two or more surfaces by the means thin wire which ultrasonically bonded to those and provides an electrical connection. While this well established in microelectronics industry its popularity rising area cylindrical lithium-ion battery pack manufacturing. Previous studies have shown that even experimental conditions process might be unstable was indicated high standard deviation bonds shear test results. This been related contamination interface between...
Wedge wire bonding is a solid-state joining process that uses ultrasonic vibrations in combination with compression of the materials to establish an electrical connection. In battery industry, this used interconnect cylindrical cells due its ease implementation, high flexibility and automation. Wire typically pack manufacturing are pure or alloyed aluminum copper. While copper wires possess better properties, force can lead cell isolator damage thermal runaway. This unacceptable result has...
This paper presents a novel method for integration of industrially-oriented human-robot speech communication and vision-based object recognition. Such is necessary to provide context task-oriented voice commands. Context-based easier, the commands are shorter, hence their recognition rate higher. In recent years, significant research was devoted gesture However, little attention paid identification objects in industrial environment (like workpieces or tools) represented by general terms used...
The aim of this study was to characterize selected properties joints made by single-sided serial resistance spot welding 0.15 mm thickness Hilumin connectors the negative terminal LGDBHG21865 lithium-ion cylindrical battery cell. Welding process performed using production parameters properly represent actual manufacturing conditions. Mechanical were examined means tensile stress test and microhardness measurements while additional studies include metallographic analysis joint cross sections...
Condition of a spindle machine tool affects not only operation the itself, but also, above all, quality machining.This paper short explains terminology and describes our own research used to measure error movements.This article impact motion inaccuracies on workpieces current state directions development presented methods.Our program written for using commercial kit also presented.
