An electrode roll connection automation apparatus is configured for uniformly maintaining the width of electrode tabs in a process of connecting electrode sheets to each other and for automatically connecting the electrode sheets to each other. The electrode roll connection automation apparatus includes first and second supply units, a connection unit, and an electrode tab sensing unit. The first and the second supply units are configured to supply first and second electrode sheets, respectively, on which electrode tabs are formed. The connection unit is configured to connect the first electrode sheet and the second electrode sheet to each other. The electrode tab sensing unit is disposed between the first supply unit and the connection unit. The electrode tab sensing unit is configured to measure the distance between the electrode tabs.

A tape attachment apparatus includes a tape supply unit configured to provide a tape to be attached to a tip of an electrode roll, a tape attachment unit configured to attach the tape provided by the tape supply unit to the electrode roll, and a frame configured to allow the tape attachment unit to be mounted to the frame. A tape attachment process to prevent unwinding of the electrode roll is automatically performed.

Tape attachment apparatus

An electrode sheet rewinding apparatus for rewinding an electrode sheet includes a bobbin having a PET film wound therearound, a bobbin holder configured to hold the bobbin, a base plate located under the bobbin holder and configured to support the bobbin holder, a roller type touch roll configured to press an electrode sheet rewound around the bobbin above the bobbin to prevent meandering of the electrode sheet, a vertical plate located at one side of the base plate, the touch roll attached to the vertical plate, and an idle roller unit configured to form a tangential line to the electrode sheet rewound around the bobbin together with the touch roll. The idle roller unit includes an idle roller configured to maintain tension of the electrode sheet and to form a tangential line to the electrode sheet and two driving mechanisms configured to change the position of the idle roller.

Electrode sheet rewinding apparatus including position-changeable idle roller

A tape removal apparatus is configured for automatically removing a tape attached to an electrode roll in order to fix the electrode roll. The tape removal apparatus includes a sensing unit configured to sense the tape attached to the electrode roll, an injection unit configured to inject air toward the tape, a support unit configured to support a non-adhesive portion of the tape, and a gripper configured to fix the non-adhesive portion of the tape together with the support unit.
