17. Machine Parameters:

1. 1.  Full Automatic Production & High Efficiency
2. The machine realizes unmanned operation throughout the entire process, including vane feeding, shaft assembly, washer/O-ring installation, oil filling, housing assembly, welding, and finished product discharging. It eliminates the low efficiency and poor consistency of manual assembly, ensuring stable and adjustable production capacity.
3.  
4. 2. Reliable PLC Control & User-Friendly Operation
5. Equipped with a PLC control system and touchscreen interface, the machine features intuitive operation, one-click parameter setting and program switching, greatly reducing the risk of human error. It also provides automatic fault alarm and protection for quick troubleshooting.
    
6. 3. Precision Pneumatic Components for Zero-Error Assembly
7. The core assembly units adopt high-precision pneumatic slides and grippers, ensuring accurate positioning and stable movement. Every component (vanes, shafts, O-rings) is assembled within strict tolerances, while avoiding scratches or damage to plastic parts.
8.  
9. 4. In-Line Quality Inspection & Defect Rejection
10. Each key process is equipped with an on-line inspection station to verify assembly quality in real time. Defective parts are automatically marked and rejected, preventing non-conforming products from entering the market and reducing after-sales risks and rework costs.
     
11. 5. High Compatibility for Multi-Specification Products
12. With flexible design, the machine can adapt to different models and sizes of soft-close shafts by simply replacing tooling fixtures, eliminating the need for new equipment development and lowering customers' capacity expansion costs.
13.  
14. 6. Low Maintenance & Long Service Life
15. Adopting well-known brand components, the machine offers high stability and low failure rates for long service life. Its modular design enables quick and easy maintenance, ensuring high cost performance over the long term.

Technical Points:

1. PLC & HMI Integrated Control Logic
2. PLC-based main control provides sequential control and interlock protection for all processes: feeding, assembly, oil filling, inspection and discharging. The touchscreen HMI integrates parameter setting, recipe management, real-time monitoring and fault alarms, enabling one-click switching between different product specifications.
3.  
4. Precision Micro-Oiling & Sealing Assembly Technology
5. The oil filling station uses a quantitative injection system to control lubricant volume, ensuring consistent damping performance and avoiding functional failure caused by incorrect oil quantity. Special tooling with force feedback ensures proper installation of O-rings and washers, preventing oil leakage and extending product life.
6.  
7. In-Line Full-Process Inspection & Defect Rejection System
8. Sensors at each key station (shaft assembly, O-ring installation, housing assembly) detect missing parts, misalignment and incomplete assembly in real time. Defective parts are automatically rejected without entering downstream processes, achieving zero-defect output and supporting production traceability.
    
9. Modular Tooling & Quick Changeover Design
10. The modular structure allows quick replacement of core assembly fixtures. By adjusting positioning blocks and fixture dimensions, the machine can adapt to different specifications of soft-close shafts, significantly reducing changeover time and improving equipment versatility.
