Description

Technical Field

[0001] The utility model relates to the technical field of battery safety detection, in particular to battery leakage detection equipment. Background Art

[0002] The society's demand for new energy batteries is increasing. The electrolyte leakage in the battery cell production process poses a great safety hazard to electrical products and personnel. The tiny leakage pore size and shape changes of the battery cannot be reliably identified by the naked eye. Therefore, a safe, accurate and reliable battery leakage detection device is urgently needed.

[0003] For example, the patent document with application number 201820937497.3 discloses a semi-automatic battery leakage detection device. The utility model discloses a semi-automatic battery leakage detection device, which includes a frame, and the frame is equipped with: a leakage detector for detecting the concentration of organic volatiles generated by battery leakage; a sealed cavity assembly for placing the battery to be tested, a vacuum assembly for performing negative pressure treatment on the sealed cavity assembly; a gas purification and delivery assembly for purifying the external air and delivering it to the sealed cavity assembly, and transferring the organic volatiles in the sealed cavity to the leakage detector for leakage detection; and a PLC. The semi-automatic battery leakage detection device of the utility model places the battery in a sealed cavity assembly, and then uses a gas purification and delivery assembly to transfer organic volatiles that may be generated by leakage to a leakage detector for detection, thereby realizing semi-automation of battery leakage detection, thereby improving the reliability and accuracy of battery detection. However, the semi-automatic battery leakage detection device needs to straighten and fix the battery before testing the battery so that negative pressure detection can be performed on the battery, which affects the detection speed.

The advantage of this arrangement is that through the arrangement of the spiral driving device 205, the sliding base plate 201 can be driven to move accurately to the bottom of the negative pressure detection device 101.

[0026] like Figure 3-Figure 4 As shown, a battery placement box 3 is installed on the upper end surface of the sliding base plate 201, and card slots 301 are provided on both side surfaces of the battery placement box 3, a fixed partition 302 is provided on the bottom surface of the battery placement box 3, and a slide groove 303 is provided on the front end surface of the battery placement box 3.
