Description

Technical Field

[0001] The utility model belongs to the technical field of new energy sodium ion batteries, and in particular relates to a sodium ion square battery helium detection and positioning device. Background Art

[0002] The helium detector is a device that uses a helium mass spectrometer leak detector to quickly locate and quantitatively measure leaks in sealed containers. It is mainly composed of three parts: a helium detector, a helium mass spectrometer leak detector, and a helium cylinder. After the battery is placed in the helium detector positioning device, the helium detector injects helium into the battery through the injection hole, and the helium mass spectrometer leak detector vacuums the outside of the battery to detect the leakage rate. After the test is completed, the battery is taken out from the helium detector positioning device. In the process of placing the battery into the helium detector positioning device and taking the battery out of the helium detector positioning device, due to the small gap between the square aluminum shell battery and the conventional positioning device, it is easy to cause scratches on the surface of the square aluminum shell battery and affect the product. At the same time, it is also inconvenient for operators to take out the square aluminum shell battery, affecting production efficiency. Utility Model Content
