Helium detection system and method

A helium detection system, comprising:

• a control device, a loading manipulator, a main detection chamber, a first vacuum pump, a first vacuum valve, a second vacuum pump, a second vacuum valve, a first negative pressure gauge, a helium pipeline, a first helium injection valve, a first helium detector, an unloading manipulator, and a re-detection chamber;
• wherein:
• the control device is configured to:
• control the loading manipulator to transfer a battery cell to a first main detection chamber, control the first vacuum valve corresponding to the first main detection chamber to open, and evacuate the first main detection chamber through the first vacuum pump;
• in a case where the evacuation of the first main detection chamber is completed, close the first vacuum valve, and perform major leak detection on the battery cell through the first negative pressure gauge;
• in a case where a detection result of the major leak detection is detection passed, control the second vacuum valve to open, to start the second vacuum pump to evacuate the battery cell;
• in a case where the evacuation of the battery cell is completed, control the first helium injection valve of the helium pipeline to open, to inject helium into the battery cell;
• and
• in a case where the helium injection is completed, close the first helium injection valve, and perform helium detection on the battery cell through the first helium detector, thereby completing a main detection operation on the battery cell;
• the control device is further configured to, in a case where the detection result of the major leak detection is detection failed:
• control a vacuum breaking valve to open, and break the vacuum of the battery cell and the first main detection chamber through an atmospheric pipeline;
• and
• control the unloading manipulator to transfer the battery cell to the re-detection chamber for re-detection, wherein the re-detection includes re-detection for the major leak detection and re-detection for the helium detection;
• and
• the first main detection chamber is any idle chamber among multiple main detection chambers;
• the first vacuum valve is connected to the first vacuum pump, and the second vacuum valve is connected to the second vacuum pump.
