FPC Bonding Adhesive Dispensing Machine — 6‑Axis Sealing Hot Melt Glue Dispenser

Product overview

This machine is designed for flexible printed circuit (FPC) bonding and inline dispensing with hot melt adhesives. It combines a stable gantry, a jetting/auger valve for angle access, multiple dispensing units, and an onboard camera for part registration and inline inspection. The system accepts cartridge or heating module, allows independent control of each dispensing unit, and stores recipes for production repeatability and traceability.

Problem → Cause → Solution

Problem: FPC assemblies often suffer from misplaced or inconsistent adhesive deposits, leading to poor bonding and rework.
Cause: Limited tool orientation, variable adhesive temperature and inconsistent actuation timing cause deposit variation.
Solution: By providing full rotation access, camera‑based registration, and precise temperature control for the feed, this unit stabilizes deposit size and position; save validated recipes to reproduce results across shifts.

Technical Specifications

Typical applications

• FPC/FFC adhesive dots and sealing for connector ends and stiffener bonding.
• Hot melt sealing for flexible display modules and sensor assemblies.
• Small potting or resin deposits for module protection and mechanical support.

How to choose

• If parts require access to multiple faces, choose this rotation module to avoid re‑fixturing.
• For filled or high‑viscosity adhesives, use heated feed and larger tip sizes to reduce clogging.
• For large‑travel dispensing needs (e.g., automotive parts), confirm travel range, nozzle reach and cycle timing with a site sample test.

Installation & maintenance

Installation: mount inline or on an indexed conveyor cell; connect mains, compressed air (if needed), conveyor I/O and network. Ensure safe grounding and guarding.
Commissioning: run material × tip × temperature × motion matrix to create validated recipes and inspection thresholds.
Maintenance: daily tip cleaning on heavy lines; regular actuator checks; monthly camera calibration and system backup.

FAQ

Q: What is the smallest deposit this unit can make?
A: Typical minimum volume is ≥0.01 μL depending on tip and adhesive; confirm with a sample test.
Q: Does the camera registration adjust for part shift?
A: Yes — the onboard camera finds reference marks and adjusts motion coordinates before dispensing.
Q: Can I use filled epoxy or only hot melt?
A: The machine handles hot‑melt and epoxies; for filled resins use heated feed and choose appropriate tips.
