The invention discloses a pole piece die-cutting machine for a lithium ion battery production line. The pole piece die-cutting machine for the lithium ion battery production line comprises a material rolling and discharging assembly and a fixing shell, a die-cutting assembly is arranged in the fixing shell, the die-cutting assembly comprises a sliding block and a base which are sequentially arranged from top to bottom, a containing groove is formed in the middle of the base, a cutter die is arranged at the edge of a groove opening of the containing groove, and a cutter groove matched with the cutter die is formed in the lower surface of the sliding block. According to the pole piece die-cutting machine for the lithium ion battery production line, the cutter die is arranged below the cutter groove, and a containing groove used for containing a cut pole piece is formed below the cutter die, that is, during cutting, the sliding block moves in the direction of the cutter die, so that the cutter die is inserted into the cutter groove to cut the pole piece, under the extrusion of the sliding block, the pole piece falls into the containing groove, the pole piece does not need to be separated from a roll material manually, and the pole piece can be completely stripped, so that the labor cost is greatly reduced, and the production efficiency of a lithium ion battery is improved.
Description
technical field [0001] The invention relates to the technical field of battery production, in particular to a pole piece die-cutting machine for a lithium-ion battery production line. Background technique [0002] During the production of lithium-ion batteries, it is necessary to cut several coiled materials according to the processed size through die-cutting equipment, so as to facilitate the subsequent production of lithium-ion batteries; [0003] The disadvantage of the prior art is that when the die-cutting is carried out, the cutting is continued on the coil material through the movement of the knife die up and down, because after cutting, most of the pole pieces are still stuck on the pole pieces. On the roll, or stuck on the die, it needs to be manually separated on the production line, and then placed neatly, the production efficiency is low, it is not convenient for the placement of the pole piece, and it is even more inconvenient for the production of lithium-ion b...
