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. ## Claims ### Claim 1 A secondary battery cell supply apparatus for a process of folding a secondary battery cell, the secondary battery cell supply apparatus comprising: 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 vertically upward; a second device configured to grip the secondary battery cell gripped by the first device and transfer the secondary battery cell in a transverse direction when the first device releases the secondary battery cell; and a third device configured to grip the secondary battery cell gripped by the second device, rotate the secondary battery cell, and move the secondary battery cell upward and downward so that a pair of wide surfaces of the secondary battery cell is directed in a vertical direction when the second device releases the secondary battery cell. ### Claim 2 (depends on 1) The secondary battery cell supply apparatus of claim 1, wherein the first device has a first gripper unit configured to grip the secondary battery cell, and a first moving unit configured to move the first gripper unit vertically upward and downward; the second device has a second gripper unit configured to grip the secondary battery cell, and a second moving unit configured to move the second gripper unit in the transverse direction; and the third device has a third gripper unit configured to grip the secondary battery cell, a third moving unit configured to move the third gripper unit downward, and a third rotating unit configured to rotate the third gripper unit. ### Claim 3 (depends on 2) The secondary battery cell supply apparatus of claim 2, wherein the pair of first gripper units, the pair of second gripper units, and the pair of third gripper units are provided. ### Claim 4 (depends on 3) The secondary battery cell supply apparatus of claim 3, wherein the third device is disposed on a route through which the second gripper unit is moved by the second moving unit. ### Claim 5 (depends on 4) The secondary battery cell supply apparatus of claim 4, wherein the third gripper unit is disposed to be opposite to the second gripper unit. ### Claim 6 (depends on 5) The secondary battery cell supply apparatus of claim 5, wherein the third gripper unit includes: a pair of gripping portions configured to press the pair of wide surfaces of the secondary battery cell; and a vacuum suction unit provided on any one of the pair of gripping portions. ### Claim 7 (depends on 6) The secondary battery cell supply apparatus of claim 6, wherein the vacuum suction unit is disposed at an upper side of the secondary battery cell when the secondary battery cell is rotated by the third gripper unit and the pair of wide surfaces is disposed in the vertical direction. ### Claim 8 (depends on 2) The secondary battery cell supply apparatus of claim 2, comprising: a first loading unit on which the secondary battery cell is placed by the third gripper unit; and a first loading/moving unit configured to move the first loading unit.
