Abstract: Disclosed is a terrace folding system of a secondary battery cell, including a transfer unit which transports a secondary battery cell; and a folding unit which is disposed along the transfer unit and is temporally separated from the transfer unit to fold a terrace of the secondary battery cell.

Abstract: A hot-press system for folding a surface of a pouch-type secondary battery, the hot-press system including: a first folded surface pressing unit configured to hold a main chamber and long-side terraces, which have folded surfaces, of a secondary battery, the first folded surface pressing unit being configured to primarily press the folded surfaces while applying heat and pressure to the folded surfaces, and a second folded surface pressing unit configured to hold the main chamber and the long-side terraces, which have the folded surfaces, of the secondary battery guided from the first folded surface pressing unit, the second folded surface pressing unit being configured to secondarily press the folded surfaces while applying heat and pressure to the folded surfaces.

Abstract: A disclosed apparatus for forming a sealing portion for folding a secondary battery pouch includes: first and second pressing bars disposed to face each other with a sealing portion for folding therebetween to apply pressure for flattening the sealing portion for folding that is defined by the edge of a secondary battery pouch for sealing an electrode assembly accommodated therein; first and second pressing surfaces provided at the first and second pressing bars, respectively, and disposed to face the sealing portion for folding; and a forming protrusion formed on the first pressing surface and configured to form a folding guide line on the sealing portion for folding by pressure applied by the first and second pressing bars.

Abstract: A disclosed heater for a sealing process of a secondary battery includes: a sealing bar heating and pressing a pouch foil to be sealed; a plurality of sub-heating unit longitudinally disposed inside the sealing bar to respectively independently supply heat to a plurality of sections separated in the longitudinal direction of the sealing bar; temperature sensing units disposed inside the sealing bar and sensing temperature at positions on the surfaces being in contact with the pouch foil; and a control unit controlling heating temperature of the plurality of sub-heating units on the basis of the temperature sensed by the temperature sensing units.

Abstract: A disclosed sizing roller apparatus for a folding process of a battery cell includes: a table fixing and supporting a battery cell; a base plate disposed on a side of the table; a plurality of sizing rollers disposed on the base plate and each having a rotation axis, which is inclined inward toward a folding portion of the battery cell, to press the folding portion of the battery cell in contact with the folding portion; and a plurality of air spray nozzles disposed on the base plate and spraying air to the plurality of sizing rollers.

Abstract: There is provided a secondary battery cell supply apparatus for a process of folding a secondary battery cell, including: a first device configured to grip a secondary battery cell for a cell folding process received in a tray and raise the secondary battery cell for a cell folding process vertically upward; a second device configured to grip the secondary battery cell for a cell folding process gripped by the first device and transfer the secondary battery cell for a cell folding process in a transverse direction when the first device releases the secondary battery cell for a cell folding process; and a third device configured to grip the secondary battery cell for a cell folding process gripped by the second device, rotate the secondary battery cell for a cell folding process, and move the secondary battery cell for a cell folding process upward and downward.

Abstract: There is provided an apparatus for folding a pouch for a secondary battery, the apparatus including: a forming means configured to gradually bend and fold an edge of a pouch-type secondary battery so that the edge has a target cross-sectional shape; a support means configured to support the forming means; and first to fourth gap spacers having various thicknesses, formed in a flat plate shape, and configured to be interposed between the forming means and the support means to align the forming means.

Abstract: There is provided a secondary battery cell transfer apparatus for a process of folding a secondary battery cell, including: multiple stations disposed at an equal interval and sequentially disposed in a straight process direction; tables provided in the multiple stations, respectively, and configured to vacuum-grip and support the secondary battery cell from below the secondary battery cell; transfer bars provided in the multiple stations, respectively; vacuum gripping units provided in the table and the transfer bar, respectively, and configured to selectively apply vacuum gripping force to the secondary battery cell; a lifting unit configured to operate a lifting operation of the transfer bar; and a straight transfer drive unit configured to operate a straight reciprocating motion of the transfer bar, in which productivity may be improved by reducing the tact time for a folding process.
