The cover supply unit 600 may be configured as a cover loading box 210, a cover transport robot.

The cover transport robot may include a traveling shaft 621, a robot body 622, a pneumatic cylinder 623, and a vacuum absorber 624. However, the cover transfer robot is preferably a one-axis robot.

Each component is the same configuration as the components of the battery cell supply unit 100, the difference is the size of the cover stacking box 610 due to the size difference between the cover 14 and the battery cell (11-a) and the vacuum absorber ( The arrangement of 624 is different and the rest are the same. Since the description of the cover supply unit 600 is the same as that of the battery cell supply unit 100, it is omitted.

While the present invention has been particularly shown and described with reference to exemplary embodiments thereof, it is clearly understood that the same is by way of illustration and example only and is not to be taken by way of illustration, It can be seen that various modifications and applications are possible. For example, each component specifically shown in the embodiments can be modified and implemented. It is to be understood that all changes and modifications that come within the meaning and range of equivalency of the claims are therefore intended to be embraced therein.
