  • Apparatus and method for inspecting welding of secondary battery
    Patent number: 11179812
    Abstract: An apparatus for inspecting the welding for a secondary battery includes: a measuring unit measuring a power value (P) supplied to the welding apparatus and a taken time (S) when the electrode tab and the electrode lead are welded to each other to obtain measured welding data (Data); an instrument unit obtaining a waveform representing a relationship between the power value (P) and the taken time (S) by using the measured welding data obtained by the measuring unit to display the waveform on a graph; and an inspection unit comparing the measured welding waveform displayed on the graph with a normal welding waveform to inspect whether the defective welding occur in real-time.
    Type: Grant
