Stable Narrow type Piezoelectric Jet Valve for LENS and VCM UV Glue Applications

The narrow-type piezoelectric jet valve is specially designed for compact production lines in LENS and VCM module assembly. It delivers high-precision, non-contact UV adhesive dispensing with excellent dot consistency and minimal satellite formation. Featuring a streamlined, non-quick-release design, the valve reduces consumable costs, enhances vibration stability, and supports up to 20 million cycles without recalibration. Its compact, lightweight structure and integrated cable system further optimize space and efficiency for high-speed, high-reliability microelectronics manufacturing.

Core Advantages

• Compact structure, strong adaptability
  The valve body is narrow and lightweight, specially designed for high-density modules such as LENS and VCM, and is easy to integrate into precision production lines with limited space.
  

• Excellent jet consistency
  The non-contact jet design combined with the multi-guide structure of the flow channel effectively suppresses the splash and scatter of glue dots, and improves the accuracy and yield of UV glue dispensing.
  

• High stability, low maintenance
  Supports ±0.01mm high repeatability calibration accuracy, life of 20 million vibration-free adjustments, meeting the needs of long-term stable operation.
  

• Consumables optimization, cost reduction
  Reduce replacement frequency and spare parts cost, and simplify maintenance process.
  

• Cable integrated design
  The power and sensor cables are integrated into one, reducing wiring complexity, improving equipment neatness and system reliability.

FAQ

Q1: Is the narrow jet valve suitable for VCM magnet bonding where space is limited and the structure is complex?
A1: Yes. The valve’s compact and lightweight design makes it ideal for tight installation spaces such as VCM magnet dispensing. It can be integrated into existing fixtures without requiring major layout changes.

Q2: Can this valve handle UV adhesives or low-viscosity fluids reliably?
A2: Absolutely. The valve is optimized for stable, non-contact jetting of low-viscosity adhesives like UV glue. Its multi-guided flow path design minimizes issues such as stringing or satellite droplets.

Q3: How is consistent dispensing accuracy maintained over long production runs?
A3: The valve delivers repeatability of ±0.01 mm and supports up to 20 million shots without recalibration. Paired with a multi-channel controller and closed-loop monitoring, it ensures excellent process stability and yield.

Q4: Is there a way to detect dispensing failures like missing shots or signal errors?
A4: Yes. The controller features real-time shot counting and missing-shot detection with alarm alerts. This helps identify signal loss or valve issues early, minimizing downtime and defects.

Q5: What about maintenance and consumables? Is the valve easy to service?
A5: The valve has a simplified structure that eliminates the need for sealing seats and O-rings, reducing consumable parts and maintenance frequency. It is designed for long-term use with minimal intervention.
