摘要： The present invention relates to an alignment inspection apparatus for an electrode assembly, which inspects alignment quality of an internal electrode laminated in the form of a sandwich between separators in a mono cell, and an align inspection method for an electrode assembly using the same.
Also, the alignment inspection apparatus for the electrode assembly including a laminate, in which a separator, an internal electrode, a separator, and an upper electrode are sequentially laminated, includes a camera unit disposed above a central portion of the electrode assembly to photograph and inspect the electrode assembly and a side lighting unit obliquely irradiating light onto each of both ends of the upper electrode, which are symmetrical to each other with respect to the central portion of the electrode assembly.-

摘要： The present invention provides a method for manufacturing an electrode assembly, the method comprising: a step of interposing a plurality of first electrodes one by one, which are spaced apart from each other, between two separators; a step of stacking a second electrode on each of outer surfaces of the separators on each of both sides of the first electrode at positions that are skipped by one of the plurality of positions on which the first electrodes are disposed to alternately continuously form a bi-cell, in which the second electrode/the separator/the first electrode/the separator/the second electrode are sequentially stacked, and a half-cell, in which the separator/the first electrode/the separator are sequentially stacked; a step of cutting the stack into a unit cell in which one bi-cell and one half-cell are connected to each other; a step of folding the unit cell so that the bi-cell and the half-cell are stacked; and a step of stacking a plurality of folded unit cells to manufacture the electrode assembly.

摘要： The present invention provides an apparatus for manufacturing a secondary battery. The apparatus for manufacturing the secondary battery comprises: a first measurement part photographing unit cells, which are continuously transferred, to measure a position of a first electrode having a relatively large size of the first electrode and a second electrode, which are provided in the unit cells and have polarities opposite to each other, from an image of each of the photographed unit cells; and a first arrangement part disposing the unit cell passing through the first measurement part at a preset position of the separation sheet to adjust an interval between the unit cells disposed on the separation sheet on the basis of the position of the first electrode, which is measured by the first measurement part.
