Abstract
The present invention relates to an electrode cutting device including a cutting unit configured to cut an electrode sheet and a fixing unit configured to fix the electrode sheet, wherein the cutting unit includes a cutter configured to cut the electrode sheet by shearing and a cutter lifting portion configured to move the cutter so as to be perpendicular to a surface of the electrode sheet, and the fixing unit includes a gripper configured to press the electrode sheet so as to be fixed, a driving portion configured to drive the gripper so as to be moved, and a sensor configured to monitor the driving portion, whereby it is possible to rapidly and accurately check whether air leaks from the driving portion, which drives the gripper.
Claims10
An electrode cutting device comprising:
- a cutting unit configured to cut an electrode sheet, the cutting unit including a cutter configured to cut the electrode sheet by shearing, the cutter configured to move towards and away from a surface of the electrode sheet;
- a support portion configured to support the electrode sheet;
- and
- a fixing unit configured to removably fix the electrode sheet to the support portion, the fixing unit including a gripper configured to press the electrode sheet against the support portion, a driving portion configured to move the gripper, and a sensor,
- wherein the driving portion is a pneumatic cylinder configured to move the gripper towards the support portion to press the electrode sheet against the support portion, and
- wherein the sensor is a pneumatic gauge sensor configured to continuously or periodically monitor a pressure of the pneumatic cylinder.
