Roll stacking device for secondary batteries

1 . A roll stacking device for a secondary battery comprising:

an input conveyor transferring cells;

a discharge conveyor spaced apart from the input conveyor; and

a roll module having a roll for stacking cells transferred by the input conveyor on an upper side of the discharge conveyor in a front and rear direction,

wherein the roll includes:

a roll body having at least one cell seating portion formed therein, and

an adsorption pad mounted on the roll body and adsorbing cells.

2 . The roll stacking device for a secondary battery of claim 1 ,

wherein the adsorption pad adsorbs the cell between the cell transferred to the cell seating portion and the roll body.

3 . The roll stacking device for a secondary battery of claim 1 ,

wherein the roll module includes:

a roll rotation mechanism rotating the roll body, and

a roll advancing and retreating mechanism moving the roll rotation mechanism in the front and rear direction to advance and retreat the roll.

4 . The roll stacking device for a secondary battery of claim 3 ,

wherein the roll module includes a pair of rolls spaced apart in a left and right direction, and

wherein the roll rotation mechanism includes:

a rotation shaft connected to each of the pair of rolls,

a rotation shaft supporter supporting the rotation shaft, and

a rotation drive source connected to the rotation shaft and rotating the rotation shaft.

5 . The roll stacking device for a secondary battery of claim 4 ,

wherein the roll advancing and retreating mechanism advances and retreats the rotation shaft supporter.

6 . The roll stacking device for a secondary battery of claim 3 , further comprising:

a vision camera sensor photographing cells adsorbed on the roll,

wherein the roll module further includes a roll correction mechanism for correcting a position of the roll in a left and right direction.

7 . The roll stacking device for a secondary battery of claim 1 , further comprising:

a cell stacker in which cells transferred from the roll are stacked in the front and rear direction.

8 . The roll stacking device for a secondary battery of claim 7 ,

wherein the cell stacker includes:

a stack body moving in the front and rear direction, and

a sub-absorbing pad arranged on the stack body and absorbing the cell.

9 . The roll stacking device for a secondary battery of claim 1 , further comprising:

an insulating screw disposed next to the discharge conveyor and separating leads of a plurality of cells.

10 . The roll stacking device for a secondary battery of claim 9 ,

wherein a pair of insulating screws are provided between which the discharge conveyor is provided.
