The invention relates to an automatic interlayer paper ring loading apparatus for a battery shell. The automatic interlayer paper ring loading apparatus comprises an assembling part and a material loading part, wherein the assembling part comprises a supporting board which can side up and down, a plurality of material barrels which are arranged on the supporting board in a run-through manner, a material blanking apparatus arranged below the material barrels, and a plurality of paper supply pipes which are arranged above the supporting board and arranged in one-to-one correspondence to the material barrels, wherein at least one material supporting apparatus is arranged on the end part of each paper supply pipe; each material barrel comprises an accommodating section and an opening section which is arranged above the accommodating section and internally connected with the accommodating section; the inner diameter of the opening section is greater than the outer diameter of each paper supply pipe; and the material loading part is used for moving arranged steel shells to the upward side of the supporting board to enable the steel shells to be in one-to-one correspondence to the material barrels. By adoption of the automatic interlayer paper ring loading apparatus, the problem that the performance of a produced battery is influenced caused by low assembling efficiency, poor assembling accuracy and high probability of damage to the paper rings in the assembling process when the interlayer paper rings are loaded into the battery shell is solved.
