Preparation device of power battery tab

The device comprises a pedestal, a supporting frame is welded to one end of the outer wall of the top of the pedestal, an air cylinder is installed at the axis of the outer wall of the top of the supporting frame through a bolt, and a lifting plate is installed at the output end of the air cylinder through a bolt; punches distributed at equal intervals are installed at the center of the outer wall of the bottom of the lifting plate through bolts, a containing groove is formed in the outer wall of the top of the pedestal, punched holes are formed in the inner wall, close to the punches, of the bottom of the containing groove, and positioning grooves are formed in the centers of the inner walls of the two sides of the supporting frame. When the lifting plate vertically moves downwards under the action of the air cylinder, the pressing plate presses the tab plate, at the moment, the abutting block moves towards the interior of the column groove under the action of the limiting plate and the spring, the stability
