Abstract:
1. A unit cell transfer apparatus for arranging and delivering unit cells to a folding device, which is used in a continuous process for manufacturing a stack/folding type electrode assembly having a structure of planar unit cells wound up over a separate film, comprising: a unit cell feeder to introduce unit cells in sequential order; a position checking part that captures an image of a position of the unit cell in the unit cell feeder to acquire an image signal and then transmits the image signal to a control part described below; the control part that confirms aligned conditions of the unit cells on the basis of image signals received by the checking part to control behavior of grippers described below; two or more grippers, each of which grips unit cells fed from the cell feeder one unit at a time and then delivers the unit cells to a transfer part described above, after position compensation of the unit cell according to a position compensation signal provided by the control part; and the unit cell transfer part for delivering the unit cells described above to a folding device, wherein the unit cell transfer part has a pair of conveyer belts arranged to face each other while rotating in opposite directions, and wherein the unit cell is inserted between the conveyer belts and delivered.
