Abstract: A device for manufacturing a battery, the device including a lower die configured to support an electrode, an upper die above the lower die and connected to the lower die while vertically spaced therefrom, a lift configured to move the upper die upward or downward, a punch on the upper die and inserted into the lower die to perform machining of the electrode, a sensor configured to detect a state of the punch, a controller configured to receive a detection signal of the sensor and monitor an insertion amount of the punch and a corrector configured to correct a height of the punch according to a control signal of the controller.

Abstract: The present disclosure relates to a frame packaging box for packaging frames. The frame packaging box includes a box comprising an accommodating space for accommodating frames, a plurality of supporters stacked up and down in the accommodating space to support portions of the frames, and a guide rail disposed on an inner surface of the box to guide the up-down movement of the plurality of supporters.

Abstract: A humid air forming device, which cools an object to be measured to a predetermined temperature, and which sprays humid air having a predetermined temperature to the cooled object to be measured, thereby forming moisture particles on the surface of the object to be measured, and a measurement system including the same. The humid air forming device includes a cooling unit that cools the object to be measured to a first temperature or lower; and a humid air supply unit that forms humid air having a second temperature, which is higher than the first temperature, and spraying the humid air toward the surface of the cooled object to be measured, thereby forming moisture particles on the surface of the cooled object to be measured.
