Abstract: A conveying system including at least three axis devices for transporting component receiving portions for receiving a component and/or a component holder on a station path along a main transport direction in a component station. The axis devices each have a carriage assembly having one of the component receiving portions and having a feed apparatus for feeding the component receiving portion from an avoidance state to a transport position, and each have a linear shaft apparatus for moving the component receiving portion in the transport position along the station path in the main transport direction and for returning the component receiving portion in the avoidance state in a reverse direction. At least two of the axis devices are linear displacement axis devices which linearly move the component receiving portion in a spatial direction of the feed apparatus. The spatial directions each define a different projection direction in a projection plane perpendicular to the main transport direction.

Abstract: A filling head for filling an electrochemical cell with electrolyte has a pre-chamber and a filling chamber, as well as a shutoff element which is movable between an open position and a closed position and releases an opening between the pre-chamber and the filling chamber in the open position and closes off the opening in the closed position. The filling chamber has a pressure port. The shutoff element is movable against a restoring force from the closed position into the open position.

Abstract: An electrochemical cell has an electrode coil, including a first and a second electrode, wherein at least one electrode has tabs, of which at least some are bent over at a first end face of the electrode coil and are electrically conductively connected to a current collector, wherein at least one surface region which is free of tabs is provided on the first end face of the electrode coil, and the current collector has an electrolyte filling opening which is arranged in the region of the at least one surface region which is free of tabs.

Abstract: A method for welding metallic foils includes the method steps of: forming a parallel joint with a plurality of metallic foils to be joined, by arranging the foils in such a way that they contact each other over a wide area, and welding the metallic foils together by directing a laser beam onto an end face of the parallel joint of the foils, such that a welded seam joining the foils is formed.

Abstract: A positioning unit includes two control carriages and a work carriage, it being possible to move the two control carriages and the work carriage on tracks that extend in parallel with one another. There is a working arm being articulated on a work base point on the work carriage and a control arm being articulated on a control base point on each of the control carriages. The control arms are articulated on the working arm at a control point of the working arm, the control point being spaced apart at a predefined lambda distance (d) from an end of the working arm that forms a working-point end and faces away from the work base point, and the two control base points and the work base point defining a triangle. At least two carriages of the two control carriages and the work carriage are movably arranged on a shared guide.

Abstract: A pressing system for a laser joining system for pressing together parts to be joined (storage cell, base plate) in the area of a joining point, includes a receptacle for accommodating the parts to be joined, a pressing element for locally pressing together the parts to be joined, in the area of the joining point, and a positioning system for the relative positioning of the pressing element and the receptacle and for pressing together the parts to be joined, during the joining process. The positioning system includes a parallel positioning device for the relative positioning of the receptacle and the pressing element in parallel to a plane (E), and an oblique positioning device for the relative positioning of the pressing element and the receptacle obliquely, in particular transversely, with respect to the plane (E) and for pressing together the parts to be joined, during the joining process.

Abstract: A joining punch for a joining device for producing a joining connection, in particular an adhesive connection, between a first joining part, for example a cover glass, and a second joining part, for example a housing, has at least one force-receiving part to which a contact force can be applied and having at least two pressing parts for applying pressure to the first joining part. The at least two pressing parts are arranged and/or formed independently of one another on the joining punch in such a manner that they are tiltable relative to the force-receiving part. The joining punch is embodied in a joining device. The two joining parts can be pressed together according to a nominal distribution of the forces or pressures, in particular uniformly using the joining device. Unevennesses and deformations of the joining parts, in particular of the first joining part, can be compensated.

Abstract: A method for joining a first join part, in particular a cover glass, with a second join part, in particular a housing and/or a display layer of a cover glass display assembly, uses a thermosensitive adhesive that is heated indirectly and/or directly by irradiation with light from a light source, in particular with infrared light and/or visible light, for producing the connection. A planar emitter is used as the light source. The method allows for a fast and secure joining of the join parts.

Abstract: A transporting apparatus for simultaneously transporting at least two substrates into a substrate-treatment apparatus to be treated in a vacuum-treatment apparatus has at least two carrier apparatuses mounted for rotation in relation to a common axis and offset axially in relation to one another. At least one retaining frame configured for supporting at least one substrate is arranged on each of the two carrier apparatuses. Each retaining frame is configured to be shifted, by rotary movement of the two carrier apparatuses about the common axis, into mutually opposite regions of a treatment unit with the two carrier apparatuses spaced apart axially from one another sufficiently such that the treatment unit is arranged between the two carrier apparatuses.

Abstract: Disclosed is a method for removing individual layers of a layer stack. The layer stack includes a semiconductor layer disposed onto an optically dense electrically conductive layer which in turn is disposed upon an optically transparent layer. A laser at a first power level is projected through the optically transparent layer and onto the optically dense electrically conductive layer. The semiconductor layer is removed through heat evaporation imparted by the laser at the first power level without removing the optically dense electrically conductive layer. Optionally, the laser at a second power level, which is greater than the first power level, is projected onto the optically dense electrically conductive layer through the optically transparent layer. The optically dense electrically conductive layer is removed through heat evaporation imparted by the laser at the second power level without removing the optically transparent layer.
