Electrode foil cutting device

Abstract

[Electrode foil cutting device for shearing an electrode foil (1) for use in an electrochemical energy storage cell, wherein the electrode foil cutting device comprises a first, frame-mounted foil cutting unit (2) with a first foil cutting edge (3), a second, movable foil cutting unit (4) with a second foil cutting edge (5) and a foil holding unit (6), furthermore a foil conveying direction (7) and an imaginary foil conveying plane (8) are provided, wherein the electrode foil (1) to be cut can be conveyed through the electrode foil cutting device in this foil conveying direction (7) on the foil conveying plane (8) and wherein the device has at least two operating modes, one of which is a foil conveying mode,in which the second film cutting device (4) is in a conveying position and the film holding device (6) is in a transport position and wherein the first and second film cutting edges (3, 5) are located on opposite sides of the film conveying plane (8) in this operating mode and wherein another operating mode is a cutting mode in which the second film cutting device (4) is moved along a cutting direction (9) into a cutting position and the film holding device (6) is moved into a shut-off position, wherein the first and second film cutting edges (3, 5) are located on the same side of the film conveying plane (8) in this cutting mode and wherein the first film cutting device (2) has a chip collection area (10) which ends at the first film cutting edge (3) and wherein this film holding device (6) has a cleaning area (11),which faces this chip collection area (10) and furthermore has a holding device cleaning channel (12) which terminates in this cleaning area (11) in at least one holding device cleaning opening (13) and wherein the first film cutting device (2) has a cutting device cleaning channel (14) which terminates in this chip collection area (10) in at least one cutting device cleaning opening (15) and wherein at least one of these holding device cleaning openings (13) and one of these cutting device cleaning openings (15) overlap in film conveying mode and wherein the cutting device cleaning channel (14) is fluidly connected to the holding device cleaning channel (12) by this overlap.]
