The invention discloses a battery nail inserting machine. The battery nail inserting machine comprises a rack, a sliding rail, a nail inserting apparatus and a conveying apparatus, wherein the sliding rail is glidingly arranged on the rack; the nail inserting apparatus is arranged on the sliding rail and used for performing plastic nail insertion on each battery; and the conveying apparatus is arranged on the rack and used for conveying a battery which is to be inserted with the nail to a working region of the nail inserting apparatus or conveying the battery which is already inserted with the nail to the outside. According to the battery nail inserting machine, a material box used for loading batteries is conveyed to a machine tool by the conveying apparatus to be fixed; after the nail inserting apparatus is positioned to nail inserting holes through a positioning assembly, nails are inserted one by one; after a single battery or multiple batteries are inserted with nails, whether the plastic nail inserting positions are correct or not is detected; the plastic nails in wrong positions are pulled out and re-inserted; after all the batteries on the material box are inserted with corresponding nails, the material box is conveyed outwardly by the conveying apparatus; and high production efficiency and lowering of labor cost are achieved.
