The invention provides a device for detecting blade battery top cover full welding sealing performance and a detection method thereof, a plurality of detection box bodies are provided, the detection box bodies are provided with a plurality of sealed cavities used for independently accommodating batteries to be detected, each sealed cavity is correspondingly provided with a helium detection module, and the helium detection modules are connected with the detection box bodies. The helium detection module can vacuumize the corresponding sealed cavity and inject helium into the corresponding to-be-detected battery; the vacuumizing assembly comprises a plurality of vacuumizing mechanisms used for vacuumizing the sealed cavity; the helium detection assembly comprises a plurality of helium detectors used for carrying out leak detection on the to-be-detected battery; and each sealed cavity is connected with each vacuumizing mechanism and each helium detector. The method comprises the steps of vacuumizing detection and
