The utility model discloses a lithium battery piece making machine which comprises a rack, and a pole piece unwinding mechanism, a pole piece winding mechanism, a pole piece conveying line, a pole piece rubberizing line, a pole lug processing line, a pole lug welding mechanism and an excess material cutting and recycling mechanism which are assembled on the rack. The tab processing line corresponds to the tab welding mechanism, the tab processing line conveys tab sections to the tab welding mechanism, the tab welding mechanism welds the tab sections and pole pieces together, the pole piece rubberizing line rubberizes the pole pieces welded with the tab sections, and the pole pieces conveyed by the pole piece conveying line sequentially penetrate through the tab welding mechanism and the pole piece rubberizing line. The excess material cutting and recycling mechanism is located between the pole piece winding mechanism and the pole piece rubberizing line in the conveying direction of the pole piece, the excess
