Description

Stacking device of electrode production system for secondary battery {APPARATUS FOR STACKING OF SYSTEM FOR PRODUCING ELECTRODES OF BATTERY}

The present invention relates to a stacking apparatus for an electrode production system for a secondary battery.

In general, a chemical battery includes a positive electrode, a negative electrode, and an electrolyte, and refers to a battery that generates electrical energy by using a chemical reaction. This is a primary battery used for single use and a secondary battery that can be used repeatedly by charging and discharging It can be classified as

Due to the advantage of being able to charge and discharge, the use of secondary batteries is gradually increasing. Among such secondary batteries, a lithium secondary battery has a high energy density per unit weight, and is thus widely used as a power source for electronic communication devices or a high-power hybrid vehicle.

An electrode used in such a secondary battery is used as a positive electrode and a negative electrode of a battery, and is used to electrically connect the battery to the outside of the battery.

The electrode is produced through a process of notching and cutting the electrode material on which electrode tabs are formed at regular intervals. The cut electrodes are loaded and stored in a magazine. In order to store the electrodes in the magazine, it is necessary to adsorb the cut electrodes and transport them to the magazine. The process of producing the electrode material as an electrode through notching and cutting proceeds continuously. If the magazine is filled with electrode material, the magazine must be replaced. During the work of replacing the magazine, there is a problem that the electrode production line must be stopped.

In addition, since a generally full magazine is discharged in a direction perpendicular to the conveying line of the electrode, there is a problem that the facility space of the stacking device increases and the movement line of the magazine replacement operation increases due to the discharge line and supply line of the magazine.

In addition, in the electrode alignment device, when the size of the electrode is changed or the displacement setting of the alignment device is changed, there is a problem in that the electrode production line must be stopped and the alignment device must be set again.
