Device For Inspecting Side Surface Of Cylindrical Battery

Abstract: According to one embodiment of the present invention, provided is a device for inspecting the side surface of a cylindrical battery which has a first region that is part of the side surface, a second region that is another part of the side surface, a third region that is another part of the side surface, and a fourth region that is the remaining part of the side surface, wherein the first region, the second region, the third region, and the fourth region are adjacent to each other and sequentially arranged along the circumference. The device comprises: a first light for emitting light in a direction toward the side surface of the cylindrical battery; a plurality of mirrors which reflect the light emitted from the first light so as to be incident on each of the first region, the second region, the third region, and the fourth region of the cylindrical battery, and include a first mirror, a second mirror, a third mirror, and a fourth mirror for reflecting back the light reflected by each of the first, second, third, and fourth regions of the cylindrical battery; and a camera into which the light reflected back by each of the plurality of mirrors is incident, and which forms an image including images of the first region, the second region, the third region, and the fourth region of the cylindrical battery.
