Abstract
The present disclosure relates to an electrode assembly manufacturing apparatus and a method for manufacturing an electrode assembly. Such an electrode assembly manufacturing apparatus and method for manufacturing an electrode assembly enable the electrode assembly to be manufactured using electrode plates that are not damaged in shape, are in a predetermined reference alignment state, and are free from foreign materials, and using separators that are not damaged in shape.
Claims21
An electrode assembly manufacturing apparatus comprising:
- an electrode plate supply portion configured to supply an electrode plate formed as a positive electrode plate or a negative electrode plate;
- an electrode plate transfer portion configured to transfer the electrode plate;
- an electrode plate moving portion configured to move the electrode plate from the electrode plate supply portion to the electrode plate transfer portion;
- an electrode plate stacking portion on which the positive electrode plate, the negative electrode plate, and a separator are stacked;
- an electrode plate conveying portion configured to convey the electrode plate, transferred by the electrode plate transfer portion, to the electrode plate stacking portion such that the positive electrode plate and the negative electrode plate are alternately supplied one by one to the electrode plate stacking portion;
- a separator supply portion configured to supply the separator to the electrode plate stacking portion;
- and
- a separator stacking portion configured to reciprocate the separator in a first movement direction parallel to a horizontal direction and a second movement direction opposite to the first movement direction, and to stack the separator between the alternately stacked positive electrode plate and negative electrode plate,
- wherein the separator stacking portion is configured to support a portion of the separator located between the separator supply portion and the electrode plate stacking portion so as to prevent folding of the separator.
A method for manufacturing an electrode assembly, comprising:
- supplying an electrode plate formed as a positive electrode plate or a negative electrode plate through an electrode plate supply portion;
- transporting the electrode plate from the electrode plate supply portion to an electrode plate transfer portion using an electrode plate moving portion;
- transferring the electrode plate by the electrode plate transfer portion;
- conveying the electrode plate, transferred by the electrode plate transfer portion, to an electrode plate stacking portion using an electrode plate conveying portion such that the positive electrode plate and the negative electrode plate are alternately supplied one by one to the electrode plate stacking portion;
- supplying a separator to the electrode plate stacking portion through a separator supply portion;
- and
- stacking the separator between the alternately stacked positive electrode plate and negative electrode plate by reciprocating the separator in a first movement direction parallel to a horizontal direction and a second movement direction opposite to the first movement direction using a separator stacking portion,
- wherein the separator stacking portion is configured to support a portion of the separator located between the separator supply portion and the electrode plate stacking portion so as to prevent folding of the separator.
