Abstract

The present invention provides a device for transferring unit cells, which is a device for aligning and transferring unit cells to a folding device in a continuous process of manufacturing a stacked / folding type electrode assembly having a structure in which plate-shaped unit cells are rolled in separation films, and comprises: a unit cell supply portion for consecutively supplying the unit cells; a position inspection unit for transmitting an image signal, which is obtained by capturing the position of the unit cells in the unit cell supply unit, to a control portion; the control portion for confirming the alignment of the unit cells based on the image signal that is received from the position inspection portion, and for controlling the operation of grippers; two or more grippers for receiving the unit cells, one unit at a time, which are supplied from the unit cell supplying portion, and for correcting the position of the unit cells according to a position correction signal from the control portion and then delivering same to a transferring portion; and a unit cell transferring portion for delivering the unit cells to a folding device.

Description

technical field [0001] The present invention relates to a folding device for an electrode assembly, and more particularly, to a unit cell transfer device for arranging unit cells and transferring the unit cells to the folding device, the unit cell transfer device having a plane Used in a continuous process of a stacked / folded type electrode assembly of a structure in which unit cells are wound on a separator, the unit cell transfer device includes: a unit cell feeder for introducing unit cells in sequence; position inspection part, the position inspection part takes pictures (or captures images) of the positions of the unit cells in the unit cell feeder to obtain image signals, and then transmits the image signals to the following control part; the control part, which is based on the The received image signal confirms the alignment of the unit cell to control the behavior of two or more grippers, after performing position compensation of the unit cell based on the position com...
