Abstract
The invention relates to a stacking device and a method for stacking flat materials, e.g. electrodes having a separation film (1) interposed in a zigzag manner by means of a guiding device (8). The stacking device comprises a stacking table (11), a holder (4; 5) for immobilizing the stack, and grippers (6, 7) for picking the electrodes (2, 3) up and putting them down in a defined manner, said grippers having an excess pressure module (9) for the targeted shaping of a defined film pocket (17) in the separation film (1).
Claims12
A device for producing electrode stacks having positive and negative electrodes (2, 3) and interposed separation film (1), to be arranged by means of a zig-zag folding, having at least one guiding device (8) for feeding the separation film (1) from an endless roll, having a stacking table (11) for receiving the electrode stack and at least one gripper (6, 7) for picking up and putting down the electrodes (2, 3), characterized in that an excess pressure module (9) is arranged at the gripper (6, 7) for generating a directed gas flow (10) such that the gas flow (10) exiting from the excess pressure module (9) forms a film pocket (17) through the redirection of the separation film (1), and that holders (4, 5) are arranged on each side of the stacking table (11), wherein a holder (4, 5) serves for the purpose of immobilizing the formed film pocket (17).
