Secondary battery electrode production system

A secondary battery electrode production system for producing a secondary battery electrode, the secondary battery electrode production system comprising:

• an unwinding portion having multiple electrode material supply reels so as to continuously supply an electrode material;
• a notching portion disposed on a path of movement of the electrode material supplied from the unwinding portion;
• a cutting portion disposed on the path of movement of the electrode material supplied from the notching portion so as to generate the electrode;
• a vision inspection portion for confirming whether the electrode is acceptable or not;
• and
• an electrode discharge portion comprising a magazine for aligning and storing the electrode while interworking with the vision inspection portion,
• wherein the notching portion comprises:
• a mold upper plate disposed above the electrode material;
• a mold lower plate disposed below the electrode material;
• and
• a driving portion connected to the mold upper plate and the mold lower plate, respectively, the driving portion comprising a servomotor and a power transfer member for transferring power from the servomotor to the mold upper plate and the mold lower plate, thereby simultaneously operating the mold upper plate and the mold lower plate upwards/downwards, and accordingly, an electrode tab can be formed by notching the electrode material,
• wherein the electrode discharge portion has a plurality of magazines for aligning and storing the acceptable secondary battery electrodes while interworking with the vision inspection portion and the plurality of magazines are automatically replaced with each other to store the acceptable electrodes without stopping the electrode production system, and
• wherein the plurality of magazines constituting the electrode discharge portion comprises a first magazine and a second magazine in a two-row structure, and each of the first and second magazines comprises a push portion for discharging the acceptable secondary battery electrode determined and supplied by the vision inspection portion to a lower side;
• a loading magazine in which the acceptable electrode discharged by the push portion is loaded;
• and a magazine conveyor for transferring the loading magazine in a direction perpendicular to a supply direction of the acceptable electrode.
