System and method for manufacturing cell stack of secondary battery

Abstract

Disclosed are a system and method for manufacturing a cell stack of a secondary battery. Thus,a separation membrane can be supplied to a stacking table that reciprocates left and right, and electrodeplates (positive and negative plates) are alternately transferred on both sides of the stacking table, and the separation membrane is folded into a zigzag while a positive plate and a negative plate are stacked in the established order to make the battery cell stack. The system comprises a stacking table, which is installed to move horizontally back and forth with the help of a linear motion device, a separation membrane supply part, which supplies a separation membrane to the stacking table; a positive electrode supply part, which is arranged on one side of the stacking table; a negative electrode supply part, which is arranged on the other side of the stacking table, supplies and stacks negative plates to the separation membrane on the stacking table; and a separation membrane guide unitwhich is arranged on the upper side of the stacking table and guides and supports the separation membrane supplied through the separation membrane supply part.

Description

technical field [0001] The present invention relates to an apparatus for manufacturing a cell stack of a secondary battery, and more specifically, to an apparatus capable of alternately transferring a separation film on both sides of a stacking table while being supplied to a stacking table that reciprocates left and right. An electrode plate (positive electrode plate and negative electrode plate), a cell stack manufacturing system and method for a secondary battery in which a cell stack is manufactured by folding a separation membrane into a zigzag shape and stacking the positive electrode plate and the negative electrode plate in a predetermined order. Background technique [0002] In general, a chemical battery is a battery composed of a pair of electrodes of a positive electrode plate and a negative electrode plate and an electrolyte, and the amount of energy that can be stored varies depending on the substances constituting the electrodes and electrolyte. This type of c...

Problems solved by technology

[0012] However, the defect in the battery cell stack manufacturing device of the secondary battery of the authorized patent No. 10-1956758 is that the faster the tack time of a single piece, the faster the rotation speed of the inclined table, thus due to the centrifugal force However, it is difficult to laminate precisely, and the possibility of failure increases
