High-Precision Dual-Drive Four-Valve Inline Dispensing System for MiniLED

The new generation High-Precision Dual-Drive Four-Valve Inline Dispensing Machine is specifically engineered for the demanding needs of modern MiniLED production lines. With advanced dual-station design and four independent valves, this system enables true synchronous or asynchronous multi-valve operation, dramatically increasing UPH while guaranteeing stable glue paths and ultra-fine dispensing accuracy. This robust inline platform is ideal for high-mix, high-volume production across Southeast Asia’s rapidly growing MiniLED supply chain — from TV backlight modules and automotive displays to high-end commercial LED signage.

Core Advantages

• Dual-Station, Four-Valve Architecture: Simultaneous or independent multi-valve operation greatly improves throughput and adapts to different glue patterns and process flows.
• Advanced Visual Alignment: Integrated high-resolution camera system guarantees precise glue placement for micro-pitch LEDs, lenses, and Dam & Fill processes.
• Flexible Process Switching: Supports rapid job changeovers with recipe storage, real-time monitoring, and automatic work area adjustment.
• Optimized for High Flatness: Dual-station setup with stable gantry motion and four-valve balance guarantees uniform surface coating, reducing overflow and improving display yield.

Main Application Areas

✓ MiniLED Backlight Module Assembly
✓ High-Pitch LED Display Panel Bonding
✓ Dam & Fill Encapsulation
✓ Lens Placement & Sealing
✓ Slit Coating & Edge Sealing
✓ FPC & PCB Underfill

Key Specifications

Q&A

Q1: Why do MiniLED lines need four valves instead of one or two?
A: Multi-valve design enables simultaneous multi-zone dispensing, doubling or tripling UPH while maintaining stable glue volume for tiny dies.

Q2: How does dual-station help with efficiency?
A: While one station runs, the other can load/unload or switch recipes, minimizing idle time and improving overall line efficiency.

Q3: How does it ensure flatness for large panels?
A: The dual-drive gantry and four-valve balance reduce glue overflow and edge bulging, producing perfect surface flatness for backlight modules.

Q4: Can it handle high-mix products?
A: Yes — each valve can be controlled independently, with fast program switching, real-time vision correction, and full MES integration.
