Flexible 2‑Channel Precision Dispensing Solution for CCM Speaker Assembly

Product Specification

Product Overview

This flexible 2‑channel dispenser is engineered for coil‑coil membrane (CCM) speaker assembly and other small acoustic components. Each channel offers independent pressure/pulse control, rapid valve response to minimize stringing, and recipe storage for quick product changeovers. The system supports common valve types, PLC/MES connectivity, and optional vision or flow feedback for inline verification and traceability.

Problem → Cause → Solution Problem

Variability in glue volume and placement during speaker assembly causes acoustic inconsistencies and higher scrap/repair rates.
Cause: Inconsistent pressure control, slow valve timing, and lack of inline feedback lead to dot/line volume variance at micro scale.
Solution: The 2‑channel system provides fine pressure/pulse control per channel, fast valve drive, and optional inline verification to stabilize deposit volume and position. Implementation steps: 1) select valve & nozzle for required dot size; 2) characterize glue viscosity vs. temperature; 3) tune pulse width and pressure during pilot runs and save recipes to MES.

Key Benefits

• Dual independent channels for multi‑point patterns or parallel heads.
• Fine pressure control and pulse shaping to reduce stringing and volume variance.
• Compact footprint for inline integration in speaker assembly lines.
• Recipe storage and MES/PLC interfaces for rapid changeover and traceability.
• Optional vision/flow feedback for closed‑loop quality control.

Applications

• CCM speaker micro‑dot and sealant deposition: consistent dot volume improves acoustic repeatability and reduces unit-to-unit variation.
• Dual‑point adhesive for suspension/lead fixation in micro‑speakers: two channels allow staged deposition without tool change.
• Small‑part acoustic assembly for wearables and earphones: compact unit fits automated lines with limited space.

How It Works

Recipe & setup: load channel pressure/pulse parameters and nozzle mapping.
Dispense action: controller issues timed pulses to valve drivers per channel to produce precise micro‑dots or beads.
Verification (optional): inline vision/flow sensor measures deposit size/placement and feeds corrections to the controller or MES.
Trace & log: process data and recipes are logged for batch traceability.

How To Choose 

Required deposit size & tolerance: determine target dot/line volume and choose valve/nozzle plus controller resolution that meets that tolerance.
Valve compatibility: confirm controller supports your valve type and driver electrical specs.
Channel needs: use 2 channels for staggered deposits or redundancy; select expansion options if future scaling is needed.
Integration: ensure PLC/MES protocol compatibility (Modbus/RS‑485, digital I/O).
Environmental rating: choose enclosure/IP options for dusty or humid production lines.

Applicable fluids

Epoxy glue, UV glue, hot melt glue, thermosetting glue, silver glue, ink, silicone, flux, red glue, conductive epoxy resin,etc.

FAQ

Q1: What types of fluids can be used with a 2-channel time-pressure dispenser?
A1: The dispenser supports a wide range of medium to high-viscosity fluids, including UV adhesives, silver paste, thermal interface materials, and even hot melt adhesives when equipped with heating modules.

Q2: Is the dispenser suitable for synchronized dispensing in high-speed production lines?
A2: Absolutely. The 2-channel design is ideal for synchronized jetting, offering high-frequency operation with excellent consistency, making it well-suited for high-speed SMT, camera modules, and microelectronics assembly.

Q3: How is maintenance handled for 2-channel dispenser?
A3: Only the nozzle and glue syringe need to be replaced or cleaned regularly to achieve a long-term and stable gluing process.
