Product Description

Air Tightness Tester (Helium Detection)

    

1,Instruction

It is used to detect the effect of laser welding and judge whether the battery after welding has holes 

 
 Workflow description:
Manually put in the battery, clamp and position the fixture, press down the measuring mechanism, vacuum and maintain the pressure, detect the discharge of helium, judge OK and ng, reset the measuring mechanism, loosen the fixture, and take out the battery.

2,Basic parameters

1. 1. Configure power supply:

AC220V,50Hz, Voltage fluctuation range:+8%~-8%;Total power: 0.5KW.

1. compressed air:

0.4MPa~0.6MPa,Barometric fluctuation ±1% (Clean air after water removal, oil-free, filtration and pressure stabilization)

1. Vacuum source:≤-0.095 kg/cm²
2. Equipment specifications:

4.1Total weight:about 0.5T
 
4.2 Size:L(1m)*W(0.8m)*H(1.6m)
4.3 Appearance color: except for the stainless steel part, the box color is computer gray.
5. Environmental requirements:
5.1 ambient temperature: 25 ± 5 ºC.
5.2 relative humidity: 30% ~ 75% RCH, which should ensure that the air on site is dry and unblocked without acid-base corrosion.
5.3 ground wire: protective grounding.

3,Specification
1.work efficiency:1ppm(34155);
2.Equipment failure rate:≤0.5%
3.Test pressure:10-100kpa
4.measurement accuracy:±0.2%
5.resolving power:1pa
6.Insulation class :A grade
7.Enclosure protection grade: Grade 6

4,Process performance
1.Applicable battery size: height 120-225mm,W 100-180mm,T 20-60mm
2. Applicable battery model of fixture: see the attached drawing
3. There shall be no air leakage during the inspection of the tested mold and battery liquid injection hole
4. The equipment is equipped with a safety light curtain alarm
5. NG products have alarm prompt and counting functions
6. When the probe is lowered, it needs to avoid the pole. The probe uses a guide rod with a diameter of 8 to install a custom seal ring to avoid the battery pole.
7. Adopt pneumatic sealing fixture, and push the electric core by the air cylinder to make the liquid injection hole of the electric core closely fit the interface of the leak detector to form a closed circuit;
8. Support positive pressure leak detection and negative pressure leak detection; Automatically track the background and provide fast and reliable measurement results
9. The optimized mass spectrometry system and intelligent algorithm ensure rapid response in all ranges, and the highly reliable vacuum system and mass spectrometry system ensure rapid helium removal
10. It supports nitrogen air breaking, is not disturbed by environmental ammonia, and quickly reduces the background. The excellent performance of the machine supports 7 * 24 hours of long-time online testing
11. The excellent performance of the machine supports high rate tests every few seconds
12. Equipped with leak detection port fine filter to filter fine impurities, so as to ensure that the machine is not affected and damaged by impurities; Double iridium wire ion source, effective system design, anti atmospheric impact
(leakage rate conversion)

5,Configuration of main components

1,Air tightness and insulation resistance detection mechanism
 
:linear guide rail
:Vacuum interface
:Lift cylinder
:Upper chamber
:Workpiece
:Inferior chamber
 
2,Core feeding mechanism
,
Use the laser to indicate the position of the liquid injection hole, and the liquid injection hole coincides with the calibration point when placing the workpiece
 
3,Cell positioning mechanism
The boss at the end of the battery is matched with the square counterbore in the lower cavity of the tooling (this matching requires good consistency)
