摘要： Discussed is a notching apparatus for a secondary battery that includes: a lower mechanism comprising a die and a die holder to which the die is fixed, the die engaging an electrode provided with a coating portion and a non-coating portion; a stripper including a first stripper pressing the coating portion and a pair of second strippers pressing and fixing the non-coating portion; an upper mechanism including a punch provided between the pair of second strippers and provided with a cutting blade cutting the non-coating portion disposed between the pair of second strippers and a punch holder allowing the punch to move in a direction of the lower mechanism; and a pressing member pressing the non-coating portion disposed between the pair of second strippers to increase in tension force when the non-coating portion is cut by the punch.

摘要： An alignment inspection apparatus for the electrode assembly including a laminate, in which a first separator, an internal electrode, a second separator, and an upper electrode are sequentially laminated, includes a camera disposed above a central portion of the electrode assembly to photograph and inspect the electrode assembly and side lights obliquely irradiating light onto each of both ends of the upper electrode. The side lights are symmetrical to each other with respect to the central portion of the electrode assembly.

摘要： An apparatus for manufacturing the secondary battery includes 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.
