Abstract
The utility model discloses a lithium ion battery cover plate assembly which comprises a current conduction terminal, a lower seal piece, a cover plate, an upper seal piece, a pole plate and a rivet, wherein the rivet penetrates the current conduction terminal, the lower seal piece, the cover plate, the upper seal piece and the pole plate in turn, and the current conduction terminal, the lower seal piece, the cover plate, the upper seal piece and the pole plate are riveted integrally by the rivet. The rivet comprises a nail head and a nail rod which are connected integrally from bottom to top, the upper part of the diameter of the nail rod is small and the lower part is big. The utility model also provides the lithium ion battery with the adoption of the lithium ion battery cover plate assembly. Because the upper part of the diameter of the nail rod of the rivet of the lithium ion battery cover plate assembly is small, and the lower part is big, when the lithium ion battery cover plate assembly is assembled, the rivet can conveniently penetrate the current conduction terminal, the lower seal piece, the cover plate, the upper seal piece and the pole plate, the operation difficulty of assembly is reduced, an operator's labor intensity is relieved, and the improvement of the production efficiency is prompted.
Description
Technical field
The utility model relates to a kind of lithium ion battery manufacturing technology, is specifically related to lithium ion battery cover board assembly and battery.
Background technology
At present the battery cover board assembly of box hat lithium rechargeable battery comprises conducting terminal, lower seal, cover plate, goes up seal, pole plate, and to run through successively and rivet by rivet be one.In the traditional handicraft, rivet such as Figure of description are shown in Figure 1, comprise ailhead 2, nail bar 3, wherein follow closely bar and be the cylinder of equal diameters up and down, and the top of nail bar is concordant, because of rivet is interference or interference fits with cooperating of upper and lower sealing, so this structure is brought following shortcoming to assembly process: 1, operation easier is big, the labour intensity height; 2, owing to the assembling difficulty influences production efficiency; 3, the assembling defective products is many, the fraction defective height.
The utility model content
The purpose of this utility model provides a kind of lithium ion battery cover board assembly of easy assembling, and the lithium ion battery that adopts above-mentioned cover plate assembly to make also is provided.
The utility model discloses a kind of lithium ion battery cover board assembly, comprise conducting terminal, lower seal, cover plate, go up seal, pole plate and rivet, rivet runs through conducting terminal, lower seal, cover plate successively, goes up seal and pole plate, and with their riveted joints for one, this rivet comprises ailhead and the nail bar that is connected as a single entity from bottom to top, and the diameter of described nail bar is up-small and down-big.
The longitudinal section of described nail bar is up-small and down-big antiparallelogram.
Further, the top chamfer of described nail bar.
Further, the top rounding of described nail bar.
The invention also discloses the lithium ion battery of the lithium ion battery cover board assembly that adopts above-mentioned arbitrary structure.
The beneficial effects of the utility model are:
Because the rivet of lithium ion battery cover board assembly nail shank diameter is up-small and down-big, thereby this lithium ion battery cover board assembly is in assembling, rivet can conveniently run through conducting terminal, lower seal, cover plate, go up seal, pole plate, greatly reduce the operation easier of assembling, alleviate the labour intensity of operator, promoted the raising of production efficiency.
Because the longitudinal section of the rivet of lithium ion battery cover board assembly nail bar is up-small and down-big antiparallelogram, make the lithium ion battery cover board assembly in assembling, rivet can conveniently run through conducting terminal, lower seal, cover plate, go up seal and pole plate on the one hand, increase work efficiency, can guarantee simultaneously can cooperate between assembling back rivet and the upper-lower seal part tight, the raising sealing.
Because the top chamfer of the rivet of lithium ion battery cover board assembly nail bar, thereby during assembling, rivet is easier to pass hole default on each assembly, has further reduced the operation easier of assembling, improves packaging efficiency, does not also influence the sealing after the assembling simultaneously.
