[0001] The utility model relates to the technical field of voltage withstand test devices, in particular to a voltage withstand test device for an aluminum alloy battery core shell. Background Art

[0002] The battery cell aluminum shell is used to store the battery cell. It needs to have a certain pressure resistance to avoid damage to the battery cell due to insufficient pressure resistance and rupture. Therefore, when manufacturers produce battery cell aluminum shells, they will conduct pressure resistance tests on the battery cell aluminum shells.

[0003] The commonly used voltage resistance test method is to first reinforce the aluminum shell of the battery cell to be tested, and then use a lower pressure plate that moves vertically downward to pressurize the aluminum shell of the battery cell. After reaching a certain pressure, if the aluminum shell of the battery cell is not damaged, it indicates that the voltage resistance of the aluminum shell of the battery cell is up to standard; conversely, if the aluminum shell of the battery cell is damaged, the voltage resistance of the aluminum shell of the battery cell is not up to standard and needs to be remade.

[0004] When the existing device tests the aluminum shell of the battery cell, it often uses manual labor to load and unload the aluminum shell of the battery cell to be tested and the aluminum shell of the battery cell that has been tested, which not only wastes a lot of labor, but also has low efficiency in loading and unloading, and is inconvenient to use.
