Tightness Testing of Automotive Energy Storage Batteries

This equipment is a helium detector for the steel shell battery after the injection hole is sealed and welded. It mainly includes processes such as battery scanning, feeding, evacuation, helium filling, helium inspection, and unloading. The helium signal in the leak detection cavity is detected by the helium leak detector, which can judge the leakage of the workpiece quickly and accurately with high precision.

Tightness Testing of Automotive Energy Storage Batteries

 

Products Introduction:

This equipment is a helium detector for the steel shell battery after the injection hole is sealed and welded. It mainly includes processes such as battery scanning, feeding, evacuation, helium filling, helium inspection, and unloading. The helium signal in the leak detection cavity is detected by the helium leak detector, which can judge the leakage of the workpiece quickly and accurately with high precision.

 

Operating Procedures: 

Workpiece loading

Vacuum chamber close

The operator connects the workpiece to the fixture and presses the start button

The system automatically seals the workpiece and closes the vacuum chamber, and the inspection cycle begins

Note: There are grating protectors on both sides of the vacuum chamber. When closing the door of the vacuum chamber, make sure that there are no objects that interfere with the movement of the vacuum chamber in the closing area.

Vacuum chamber evacuation,

Workpiece evacuation and gross leak detection

The system automatically evacuates the vacuum chamber until the vacuum degree in the chamber reaches the set pressure of starting testing.

Simultaneously:

The system automatically evacuates the workpiece until the pressure in the workpiece reaches the set value.

The system automatically maintains the pressure of the workpiece, and verifies whether there is a gross leakage in the workpiece according to the pressure drop value in the workpiece.

If the pressure in the workpiece exceeds the set range, it means that there is a gross leakage in the workpiece. The system automatically discharges the high-pressure gas in the workpiece, fills it with the atmosphere, stops the leak detection process, and the gross leakage is displayed on the operation interface.

If the pressure value in the workpiece does not exceed the set range, the workpiece leakage detection is qualified.

Workpiece evacuation

The system continues to vacuum the workpiece until the vacuum degree in the workpiece reaches the set vacuum value.

Workpiece helium filling

and

Vacuum helium inspection

The system automatically fills the workpiece with helium at the set pressure until the pressure in the workpiece reaches the set value.

The system automatically verifies the fine leak of the workpiece

If the leak detector detects that there is a helium signal exceeding the set value in the vacuum chamber, it means that the workpiece has a fine leak, and the operation interface displays a fine leak alarm signal

If the leak detector does not detect that there is a helium signal exceeding the set value in the vacuum chamber, the workpiece detection is qualified, and the operation interface displays a qualified signal

Vacuum chamber filling

and

 Helium recovery

The system automatically fills the vacuum chamber with atmosphere.

Simultaneously:

The system automatically recovers the helium gas in the workpiece to the set pressure.

Workpiece unloading

Workpiece is qualified

Vacuum chamber door opens automatically.

The operator disconnects the workpiece from the vacuum chamber connector.

The operator places the qualified workpiece into the qualified area

Workpiece is unqualified

Manually press the confirmation button, the vacuum chamber door will open automatically.

The operator disconnects the workpiece from the vacuum chamber connector.

The operator places the unqualified workpiece into the unqualified area.

The device alarms during workpiece detection

Manually press the confirmation button, the vacuum box door will open automatically.

Press the touch screen fault information prompt, cancel the alarm state, and then re-detect the workpiece.
