Cutting-off apparatus and battery assembly line production equipment

A battery assembly line production equipment, comprising:

• a cutting-off apparatus for an electrode stack, the electrode stack comprising a first electrode plate, a second electrode plate, and a separator configured to separate the first electrode plate from the second electrode plate;
• and
• a winding start mandrel and a roll-up mandrel, wherein the winding start mandrel and the roll-up mandrel are sequentially arranged along a feeding direction of the separator;
• wherein the cutting-off apparatus comprises:
• a slitting mechanism comprising a slitting element configured to be placed in a cutting-off position and cut off the separator located between the winding start mandrel and the roll-up mandrel;
• and
• a supporting element connected to the slitting element and is capable of providing a supporting force to a target electrode plate;
• a first adjusting apparatus connected between the supporting element and the slitting element and configured to adjust a position of the supporting element relative to the target electrode plate in a breadth direction of the target electrode plate;
• and
• a second adjusting apparatus connected between the supporting element and the first adjusting apparatus to enable the supporting element to rotate around an axis, wherein the axis and the breadth direction of the target electrode plate are parallel to each other,
• wherein the target electrode plate is one of the first electrode plate and the second electrode plate, located on an inner side of the electrode stack ready to be wound before being fed to the winding start mandrel, the inner side of the electrode stack ready to be wound being a side closer to the winding start mandrel.
