Electrode sheet processing device, battery production line, and control method for electrode sheet processing device

An electrode sheet processing device, comprising:

• an unwinding mechanism, wherein the unwinding mechanism is configured to carry a wound electrode sheet to be processed;
• a tab forming mechanism, wherein the tab forming mechanism is disposed on an extension path of the electrode sheet to be processed and is configured to cut the electrode sheet to be processed;
• a scrap removal mechanism, wherein the scrap removal mechanism is disposed on an extension path of a cut electrode sheet and is located on a side of the tab forming mechanism away from the unwinding mechanism, and the scrap removal mechanism is configured to remove waste material formed after the electrode sheet to be processed is cut;
• and
• a slitting mechanism, wherein along the extension path of the cut electrode sheet, the slitting mechanism is disposed on a side of the scrap removal mechanism away from the tab forming mechanism, and the slitting mechanism is configured to slit the cut electrode sheet;
• the slitting mechanism comprises a first support base, a second support base, a first knife shaft, a second knife shaft, a slitting knife, and an adjustment assembly;
• wherein along a radial direction of the first knife shaft, the first support base and the second support base are connected;
• the first knife shaft is rotatably disposed on the first support base, the second knife shaft is rotatably disposed on the second support base, and the first knife shaft and the second knife shaft are disposed in the same axial direction;
• the corresponding slitting knives are respectively disposed on the first knife shaft and the second knife shaft;
• the adjustment assembly is disposed between the first support base and the second support base, and along the radial direction of the first knife shaft, the adjustment assembly is configured to adjust a distance between the first support base and the second support base.
