Dual‑Drive Automatic Glue Dispensing Machine — Four‑Valve Inline Automated Epoxy Dispenser

Product overview

This dual drive automatic glue dispensing machine is an inline production system engineered for epoxy dispensing tasks (underfill, potting, dispensing) requiring multiple synchronous deposits. Core features: dual servo drives for synchronized motion, four independent dispense valves, syringe cartridge or heated feed compatibility, integrated vision alignment/AOI, recipe storage and MES/PLC interfaces for traceable inline manufacturing.

Problem → Cause → Solution

Problem: Multi‑point epoxy deposition in inline production often yields inconsistent volumes, long cycle times and rework.
Cause: Single‑head processes, unstable adhesive temperature and poor registration produce volume variance and misplacement.
Solution: This system uses dual high‑stability drives plus four valves for parallel dispensing, inline vision for fiducial alignment and heated feed or syringe control to stabilize viscosity—validate and lock recipes for repeatable high‑throughput production.

Key Specifications

Applications

• Inline epoxy dotting and bead dispensing for PCB underfill, potting and component fixation.
• Multi‑point adhesive deposition for sensor modules, connectors and power modules.
• High‑throughput lines needing parallel deposits with traceability and AOI verification.

How it works

1. Feed & prep: load syringe cartridges or connect heated feed line and set target temperature.
2. Recipe & alignment: load recipe or receive from MES; conveyor indexes parts and vision aligns fiducials.
3. Parallel dispense: dual drives position gantry while four valves deposit per recipe; valves operate independently or synced for pattern.
4. Verify & log: AOI inspects deposits; process and batch logs stored to MES.

How to choose

Deposit size & pattern density: for many small deposits use piezo/VCM valves; for filled/high‑viscosity epoxies use piston/peristaltic pump options.
Throughput requirement: choose 4‑valve parallel configuration and multi‑nozzle banks to meet UPH targets.
Adhesive handling: for filled epoxies enable heated feed and appropriate nozzle sizes to avoid clogging.
Integration: confirm required MES/PLC protocols and I/O mapping for inline synchronization.

Installation & maintenance

Installation: inline conveyor integration; connect mains power, compressed air (if pneumatic), grounding and network I/O. Provide safety guarding and hot‑part shielding where required.
Commissioning: run adhesive × nozzle × temperature × speed matrix to create validated recipes and AOI acceptance criteria.
Maintenance: daily nozzle cleaning in high‑use lines; scheduled valve cartridge inspection; periodic vision calibration and gantry lubrication.

FAQ

Q: What valve types are supported?
A: Supports piezo/VCM valves for micro‑dots and piston/peristaltic pumps for filled/high‑viscosity epoxies—confirm electrical/driver specs for specialized valves.
Q: How are recipes managed?
A: Recipes can be stored locally and pushed/pulled via MES; each recipe includes valve timing, volume, motion path and temperature settings.
Q: Can the four valves run different patterns concurrently?
A: Yes—each valve is independently programmable for distinct patterns or can be synchronized for identical parallel deposits.
