Brushless servo motor driven Precision dispensing valve KSP0450 for FPC connector PIN needle application

The eccentric screw valve offers a high-precision volumetric dispensing solution ideal for filling PIN areas in FPC connectors used in new energy applications. It provides consistent, bubble-free dispensing of UV adhesives and epoxy resins, ensuring complete internal filling and reliable surface coverage without missed PINs. Its servo-driven rotor-stator mechanism delivers stable, non-pulsating flow, making it suitable for handling high-viscosity fluids with excellent repeatability. This dispensing technology ensures airtight sealing, enhances insulation, and improves long-term reliability of the connector. Designed for integration into automated production lines, the eccentric screw valve is an optimal choice for precision dosing in EV battery modules, solar inverters, and smart energy systems.

Core Advantages

• Stable filling: no bubbles, no glue breakage, adapting to the tiny gap structure of precision connectors

• High consistency: each PIN position and cavity can achieve consistent glue dispensing to meet quality control requirements

• Compatible with UV/epoxy glue: to cope with different process paths of light curing or heat curing

  Improve yield: avoid problems such as empty filling, bubbles or leaks, and improve welding and sealing performance

Main appliaction

• Mobile Phone CCM Conductive Gluing
• Pad Magnet Bonding
• Mobile Phone Motherboard Thermal Grease Coating
• In-vehicle Camera AA process

FAQ

1. Can the eccentric screw valve ensure complete filling around FPC connector PINs without air bubbles?
Yes. The valve delivers a continuous, non-pulsating flow that enables full internal filling around PINs. Its low-shear volumetric dispensing minimizes air entrapment, ensuring bubble-free results.

2. Is the screw valve suitable for high-viscosity adhesives like UV glue or epoxy?
Absolutely. The eccentric screw valve is designed to handle a wide range of viscosities, including thick and filled adhesives such as UV-cure resins and thermally cured epoxies.

3. How does the valve avoid missing or underfilling individual PINs?
With precise volumetric control and programmable flow rates, the valve ensures uniform dispensing across all PIN locations, eliminating skipped or insufficiently filled areas.

4. Is the system compatible with automated high-speed production lines?
Yes. The valve features a compact design and servo-driven control system, making it easy to integrate into automated dispensing platforms for mass production environments.

5. What material is used for the stator, and is it compatible with reactive adhesives?
The stator is made of chemically resistant FFKM material, which is compatible with aggressive adhesives like UV and epoxy, ensuring durability and long service life.
