Product Description

Product Overview

This auger valve uses a brushless servo drive and positive displacement feed to give stable, repeatable material delivery. Designed for production use, the unit supports a wide range of adhesives and pastes and mounts easily on robot end effectors. The focus on repeatability reduces rejects and minimizes per‑part variation on long runs.


Problem

Many dispensing stations see variation in deposit volume and bead shape over time, causing rework and lost yield.


Cause

Volume drift commonly results from uneven feed, pressure pulses, or uncontrolled drive speed. Small disturbances become visible on tiny pads or when many parts are processed in sequence.


Solution

This servo driven auger valve pairs tight motor control with a positive displacement head so flow follows rpm precisely. The result is consistent per‑shot volume and stable continuous beads with minimal tuning. Quick‑disconnect access and standard nozzle adapters make maintenance and changeover fast.

Application

  • Precision adhesive dots for PCB, connector, and sensor assembly.
  • Reproducible bead starts for potting and gap filling.
  • Automated dispensing in robotic workcells where consistent per‑part dosing is critical.
  • Pilot and production lines that require low variation and easy maintenance.


How It Works 

The auger screw rotates to move material forward at a rate set by servo rpm. Encoder feedback keeps motor speed stable so delivered volume is proportional to rpm. For per‑cycle dosing, the controller runs a timed motor pulse to deliver the set volume. The short fluid path and positive displacement reduce air sensitivity and avoid pressure pulses at the nozzle.


How To Choose

  1. Confirm target deposit size per part and choose a nozzle diameter to match bead width.
  2. Provide fluid viscosity at working temperature and any filler content to verify auger clearance and wetted material.
  3. Decide feed method: pressure pot for long runs or gravity pot for bench use. Use a stable regulator if pressure feeding.
  4. Check robot flange and electrical interface; we advise encoder feedback for closed‑loop verification.
  5. Request a bench test for filled or marginal fluids to confirm repeatability and nozzle life.


FAQ

Q1: What does 98% repeatability mean for my line?
A1: It indicates low shot‑to‑shot variation once the system is tuned and feed is stable; actual numbers depend on fluid and nozzle choice.

Q2: How small a deposit can this valve make?
A2: Typical minimum deposits range from about 5–15 µL depending on nozzle and pulse tuning. For smaller nL work consider a piezo valve.

Q3: Can it handle filled adhesives?
A3: Yes for mildly filled materials; use coated wetted parts and request a bench wear test for abrasive fillers.

Q4: Is encoder feedback required?
A4: Encoder feedback improves closed‑loop stability and makes repeatability easier to achieve; we recommend it for tight tolerance production.

Q5: Do you offer sample testing?
A5: Yes. Send your fluid spec (viscosity at working temp and SDS) and target deposit; we will run bench tests and return settings and logs.
