Abstract

The invention provides a lithium battery leakage detection device, which includes a detection cylinder, one end of the detection cylinder is open, and the other end is sealed and connected with a detachable base, and the joint between the base and the detection cylinder is provided with a liquid seal groove. In the lithium battery leakage detection device of the present invention, the detachable structure of the detection cylinder and the base facilitates the insertion and removal of the battery to be tested and the disassembly and cleaning of the device; the setting of the sealing pad can further improve the airtightness of the device; The detection liquid is used to submerge the battery to be tested and cooperate with the liquid seal tank to check the air tightness of the device, which can solve the problem of low detection accuracy in the prior art, and at the same time has the advantages of simple structure and low cost.

Description

technical field [0001] The invention relates to the field of battery sealing detection, in particular to a lithium battery leakage detection device. Background technique [0002] Lithium batteries have the advantages of high voltage, high specific energy, many cycle times, and long storage time. They are not only widely used in portable electronic devices such as mobile phones, digital cameras and laptop computers, but also widely used in electric vehicles and electric bicycles. And large and medium-sized electric equipment such as electric tools. The internal working environment of the lithium battery must be completely isolated from the external environment of the battery to ensure the normal operation of the battery. Technically, this is achieved by welding or colloidal sealing. The quality of the sealing directly determines whether the battery can work normally. [0003] If there is a problem with the sealing of the battery and the internal and external environments are...
