Inline Visual Dispensing Machine for Vent Hole Sealing in Optical Modules
In modern consumer electronics, tiny optical modules — like camera lenses and sensor units — often include vent holes to balance internal pressure during manufacturing. These small openings must be reliably sealed with high-precision adhesive to ensure dust resistance, moisture protection, and long-term stability.
The Mingseal FS600 Series Inline Visual Dispensing Machine is purpose-built for this delicate vent hole sealing process, offering manufacturers a compact, stable solution for consistent micro-dot dispensing with smart inspection features.
Key Advantages
- Micro-Dot Precision: Critical for sealing tiny vent holes without overflow or spread.
- Standalone + Inline Dual Mode: Switch between independent operation and fully integrated inline production to match different production plans.
- Smart Presence Detection: Any missing or incomplete dot is immediately flagged to prevent defects from passing downstream.
- Compact Footprint, Large Working Area: The flexible workspace design (280×180mm or 400×400mm) fits different lot sizes and module dimensions.
Typical Applications
✔ Vent hole sealing for small camera lens units
✔ Micro cavity sealing in optical sensor modules
✔ Pinpoint glue dots for micro air vent closures
✔ Dust- and moisture-proof adhesive for tiny optical housings
✔ Precision glue tasks for pressure equalization holes in mini devices

FAQ
Q1: Why do optical modules need vent hole sealing?
A: Vent holes help balance internal air pressure during production but must be sealed tightly to prevent dust and moisture from entering the final device.
Q2: What makes micro-dot dispensing difficult?
A: The glue dot must be tiny, perfectly placed, and consistent across hundreds of parts. Any overflow can block the hole or contaminate nearby surfaces.
Q3: How does the FS600 help keep dot size small?
A: The single-valve configuration and stable mineral base reduce vibration and allow exact control of flow rate, ensuring each dot stays within spec.
Q4: Can the machine switch between batch and inline modes?
A: Yes — use the self-contained loader for smaller jobs or connect the machine inline for high-volume runs with larger panels.
