Abstract

Proposed are a device and a method for inspecting an air void at a lead film of a battery to simply and accurately perform total inspection of a gap between a lead film and the lead tab boundary by using an OCT, wherein an object to be inspected in which the lead film is attached to a lead tab is conveyed through a conveying device, the conveyed object is gripped and loaded to an inspection position, the object is aligned to form an OCT focus on an interface between the lead tab and the lead film of the object, a gap inspection image between the lead tab and the lead film is obtained by scanning the interface between the lead tab and the lead film by using an OCT scanner above the inspection position, and the obtained gap inspection image is analyzed, thereby determining fusion quality of the lead film.
