摘要： An apparatus for manufacturing a unit cell cuts lower and upper separators between sets of adjacent electrodes. In a state of a process of manufacturing the unit cell, the lower and upper separators continuously move in a longitudinal direction; and the electrodes are stacked between the separators and on the upper separator, respectively. The apparatus includes a lower block disposed under the lower separator and an upper block vertically aligned with the lower block above the upper separator. A lower end of a cutter is installed for access to the inside and outside. The upper block descends to press the separators to a surface of the lower block. One or both of the upper and lower blocks is heated to a predetermined temperature to thermally fuse pressed points of the separators. The cutter protrudes from the upper block to perform cutting at points at which the separators are pressed.

摘要： The present technology relates to an apparatus for cutting an electrode of a battery, and the apparatus includes: an all-in-one cutting cartridge module including an upper knife and a lower knife; and a cradle where the all-in-one cutting cartridge module is mounted.
Herein, the all-in-one cutting cartridge module includes a module frame and an upper knife holding unit which fixes and supports the upper knife and is supported in a manner that is vertically slidable on the module frame, and the lower knife is coupled to a lower portion of the module frame to face the upper knife.
The assembly work is very simple in the electrode cutting apparatus of the present invention. Further, since the upper knife and the lower knife are installed at the module cartridge, it is possible to quantitatively adjust the clearance and straightness of the upper knife and the lower knife in advance.
