A robotic wire termination system for efficiently and accurately connecting a plurality of wires to an electrical connector having a plurality of connector pins with corresponding wire receptacles. The system generally includes a housing, a removable alignment plate, a robotic positioner, a heating device, a touch responsive display, and a control unit. The alignment plate removably holds a selected electrical connector in a specific position and orientation with the connector pins exposed in the housing and the wire receptacles exposed outside. The display provides a visual representation of the connector pins and selections of the connector pins. The control unit receives inputs indicating the pin selections and controls the robotic positioner to sequentially move the heating device along three orthogonal longitudinal axes to a series of heating positions relative to the selected connector pins to provide heat for melting solder to connect wires to the wire receptacles.

A method of analyzing a welded connection during laser welding of workpieces includes acquiring a first measurement signal for a process radiation generated during laser welding, acquiring a second measurement signal for a laser radiation reflected by the workpieces, determining whether there is a gap between the workpieces based on the first measurement signal, and when it is determined that there is a gap, determining based on the second measurement signal whether there is a welded connection.

A method for welding at least three cables, each with two conductors protruding from the sheath ends of the cables includes stripping ends of the first conductors and stacking from opposite directions atop one another forming a first stack. The stripped ends of the second conductors are stacked atop one another from opposite directions at a working distance from the first stack forming a second stack. The first stack is arranged in a welding area of a welding device and welded to a first welding point, while the second stack is arranged in a waiting area spaced by the working distance from the welding area. The first welding point is moved by the working distance from the welding area to a storage area, while the second stack is moved by the working distance from the waiting area into the welding area and is welded to a second welding point.

A method for producing an active part (1) for a rotary electric machine (101), comprising the following steps: providing a core (2) for the active part (1) and shaped conductors (6) inserted into the core; joining together, in each case, two of the end areas (9) so that the two end areas (9) form a pair (10); and welding each pair (10) of the end areas (9) by means of a laser beam which is guided on the end areas (9) of the pair (10) along a first trajectory (13).

The present invention relates to a method for inspecting a welding quality of an electrode tab-electrode lead welded portion of a pouch-type lithium secondary battery, and the method includes: recognizing welding traces of the welded portion by a vision inspection device; measuring a size of each of the recognized welding traces; and determining whether the welded portion has been weakly welded, excessively welded or normally welded by comparing the measured size with a reference value.

A rechargeable battery pack unit encompassing a rechargeable battery cell, which includes a cell pole, and encompassing a current collector, the cell pole being integrally joined to the current collector in a connecting area, a ratio of a wall thickness of the cell pole and the thickness of the current collector being maximally, and the current collector being made of copper.

Discussed is a battery pack including a battery cell that can include a pair of electrode leads including a positive electrode lead and a negative electrode lead, a pack housing configured to receive the battery cell therein, and a protection circuit module (PCM) having a protection circuit formed on a printed circuit board (PCB), the protection circuit being configured to control operation of the battery cell, wherein the pair of electrode leads may be directly bonded to a surface copper foil layer of the PCB. The pair of electrode leads may be directly bonded to the surface copper foil layer of the PCB by a laser welding.

A button-type secondary battery includes an electrode assembly in which electrodes and separators are alternately layered; a can case having an internal accommodation space in which the electrode assembly is accommodated; and an electrode tab having one side connected to each of the electrodes of the electrode assembly and the other side welded to the can case. A welding pattern appearing at a welding part, at which the electrode tab is welded to the can case, includes a circular shape and an additional shape in addition to the circular shape.

A flux resin composition includes an epoxy resin, an imidazole compound, a thixo agent, and an activator. The epoxy resin includes at least one resin selected from the group consisting of naphthalene epoxy resins, biphenyl aralkyl epoxy resins, trisphenol methane epoxy resins, biphenyl epoxy resins, and dicyclopentadiene epoxy resins. The content of the at least one resin is equal to or greater than 20% by weight with respect to a total weight of the epoxy resin.
