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 device for an electrode production system for a secondary battery.

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

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

The electrode is produced through a process of notching and cutting the electrode material on which the electrode tab is formed at regular intervals. The cut electrode is loaded and stored in a magazine. In order to store the electrode in the magazine, it is necessary to absorb the cut electrode and transport it to the magazine. The process in which the electrode material is produced as an electrode through notching and cutting proceeds continuously. If the magazine is full of electrode materials, the magazine should be replaced. There is a problem that the electrode production line has to be stopped during the operation of replacing the magazine.

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

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.
