Automatic Vacuum Chamber Helium Leak Detection Line for Automotive Air-conditioning Components
The system is highly automated. Except for loading/ unloading workpieces, other steps are automatically controlled and operated by the system, including:
automatically clamping and sealing workpieces , vacuuming workpieces, processing gross leakage detection, sorting OK /NG products after gross leakage detection, and helium filling into workpiece;
automatically transfer the workpiece into the vacuum chambers, processing fine leakage detection, and automatically discriminate the test results;
sorting OK /NG products after fine leakage detection;
automatically recover helium gas.
Therefore, only one operator is required for the entire process.
Basic technical indicators:
| Test Workpiece | Automotive / air conditioner components |
| Workpiece Fixture | Customized according to client's workpiece, different fixtures to match different products |
| Operation Procedures | 1. Load workpiece (manual) 2. Clamp, seal, vacuum, detect gross leak, sort OK/NG products after gross leakage detection, fill helium into workpiece (automatic) 3. Detect fine leakage (four stations, automatic), sort OK/NG workpiece after fine leakage detection (automatic) 4. Recover helium (automatic, optional), release workpiece fixture (automatic) 5. Unload workpiece (manual) |
| Vacuum Chambers | Quantity can be customized, each chamber can detect one workpiece |
| Tracer Gas | Helium |
| Pre-vacuum of Workpiece | ≤500 Pa |
| Pressure for Fine Leak Test | 1.5 MPa, downward adjustable (or cusotmized according to client's testing requirements) |
| Pressure for Gross Leak Test | 1.2～2.5 MPa (or cusotmized according to client's testing requirements) |
| Reject Point | 2g/a(R134a)equal to 1.05E-6Pa.m3/sec. (or cusotmized according to client's testing requirements) |
| Test Cycle | 15s/pc (or cusotmized according to client's testing requirements) |
| Helium Recovery (Optional) | Automatic recycling system, helium recovery rate≥95% |
Basic functions:
The operator puts the workpiece on the fixture, and the system can complete the entire program of sealing, vacuuming, detecting gross leakage, sorting OK/NG workpiece after gross leakage detection, and filling helium into the workpiece outside the vacuum chamber; detecting fine leakage of the workpiece in the vacuum chamber, sorting OK/NG workpiece after fine leakage detection; recovering helium, unclamping workpiece. Production cycle is fast, and the leak detection accuracy is high.
Main configuration:
The main configuration of the equipment uses a variety of imported brand-name industrial components and can provide sufficient protection from the quality of the components to the overall reliability of the equipment. The materials of mechanical parts are made of excellent materials, and high-level processing technology ensures the reliability of the equipment.
