The invention relates to an aluminum shell battery helium-filling and nailing device and method. The aluminum shell battery helium-filling and nailing device comprises a base, a vacuum sealing cavity, a horizontal guide rod, a battery jig, a jig cylinder, a helium filling mechanism, a nailing mechanism and a sealing cavity vacuumizing device. The aluminum shell battery helium-filling and nailing method comprises the steps of placing a material on a battery, placing a sealing rubber nail, closing the vacuum sealing cavity, vacuumizing the interior of the battery and filling helium in the interior of the battery, pressing in the sealing rubber nail, and then taking out the battery. According to the aluminum shell battery helium-filling and nailing device and method, the battery and the sealing cavity are respectively vacuumized in the sealing cavity, the helium is injected in the battery shell by utilizing a pressure difference, and the sealing rubber nail is pressed into a battery filling hole in a negative pressure environment, so the interior of the battery is ensured to be in the negative pressure after the aluminum shell battery is taken out of the vacuum sealing cavity 2, and no leakage of the helium filled in the battery shell is ensured to reach to a measurement standard when the aluminum shell battery moves to the next procedure.
Description
technical field [0001] The invention belongs to the technical field of aluminum case batteries, and specifically refers to a helium-injecting nailing device and a method thereof for aluminum case batteries. Background technique [0002] At present, with the increasingly severe environmental protection issues, more and more people accept environmentally friendly electric vehicles, and the popularity of environmentally friendly electric vehicles has positive significance. Therefore, the demand for large-capacity aluminum-cased power batteries is also increasing, and the safety of batteries will be paid more and more attention. Among them, helium detection is widely used as a detection method. If high-purity helium cannot be injected into the battery, or the helium cannot be completely sealed inside the shell after injection, the battery will not meet the safety requirements in the subsequent helium inspection process, and the product quality will not be guaranteed. Therefore,...
