Automatic charging barrel feeding and discharging device and pole piece winding equipment

The utility model relates to an automatic charging barrel feeding and discharging device and pole piece winding equipment, which are used for transferring a charging barrel to a working position on a winding shaft or enabling the charging barrel to be separated from the winding shaft and comprise a supporting mechanism, and a grabbing mechanism and a driving mechanism are installed on the supporting mechanism. The driving mechanism is used for driving the grasping mechanism to reciprocate in the axial direction of the reel; the grabbing mechanism comprises a grabbing hand and a lifting driving piece used for driving the grabbing hand to do reciprocating motion in the radial direction of the reel. According to the utility model, the gripper is in contact with the charging barrel, the lifting driving piece can enable the gripper to move to a position suitable for pushing or pulling the charging barrel, and the gripper can move along the axial direction of the reel under the driving of the driving mechanism, so
