3 Axis Cantilever Epoxy Dispensing Machine for PCB, LED Driver and Transformer Potting

KPD 3 axis two component glue dispensing machine is an automatic XYZ robotic dispensing system for 2-part (AB) adhesives. It integrates automatic metering, static/dynamic mixing and precision dispensing in one desktop gantry robot.
This 3-axis AB glue dispenser accurately mixes epoxy, polyurethane, silicone two-component glue at adjustable ratios and performs programmable point, line, arc, circle and 3D trajectory dispensing for electronic potting, encapsulation and sealing.

Key Features

✅ Precision Meter & Mix System High precision pump system for two-component glue, stable ratio control 1:1~10:1, consistent dispensing volume, avoid over-dispensing or shortage.

✅ Real-time Online Mixing AB glue mixes at static/dynamic mixer tip. No glue solidification inside tank or pipeline, reduce material waste.

✅ PLC + Touch Screen Intelligent Control Save multiple dispensing programs, easy parameter setting, USB program import, password protection.

✅ Optional Vacuum Potting Function Vacuum chamber degassing to eliminate air bubbles for compact, smooth potting layer, critical for high voltage electronics.

✅ Wide Material Compatibility Work with epoxy resin, PU polyurethane resin, 2K silicone, thermal conductive AB compound, doming resin.

✅ Anti-dripping & Anti-drawing Design Glue suck-back function, clean glue cut, no dripping at nozzle.

✅ Customizable Automation 3/4 axis motion platform, rotary table, conveyor inline integration, heating & stirring tank, automatic flushing.

✅ Low Material Level Alarm Alert when A/B glue runs low, prevent machine idle running and damage.

Advantages

1. Reduce manual potting cost, greatly improve production throughput and product consistency.
2. Minimize bubble defect rate for electronic encapsulation, enhance insulation & waterproof performance.
3. Stable ratio control to avoid bad batch caused by manual mixing.
4. Modular structure, easy maintenance and spare parts replacement.
5. OEM & ODM available, tailor-made for different product sizes and glue formulas.
6. 12-month warranty, overseas technical support and remote debugging.

Working Principle

Step 1: Material Preparation & Tank Conditioning

✅Heating: Electric heating bands reduce viscosity to ensure smooth flow.

✅Agitation: Continuous stirring prevents filler sedimentation (e.g., thermal conductive powders).

✅Vacuum Degassing: Removes micro-bubbles under negative vacuum pressure ($< -0.095text{ MPa}$) prior to feeding into pumps.

Step 2: High-Precision Metering & Proportioning

✅Dual servo motors drive precision gear or piston pumps to draw Resin (A) and Hardener (B) from separate stainless steel pressure vessels.

✅System monitors volumetric flow rate continuously to enforce precise stoichiometric mixing ratios ($1:1$ up to $10:1$).

Step 3: Mixing Mechanism

✅Dynamic Mixing: A high-speed rotating motor mixes viscous or high-ratio liquids inside an easy-clean dynamic chamber.

✅Static Mixing: Helical mixer nozzles force material layers to cross-divide repeatedly for low-viscosity or quick-curing formulas.

Step 4: Dispensing & Potting

✅Servo-driven XYZ robotic gantry or multi-axis CNC system executes preset potting trajectories (dots, lines, arcs, continuous potting) over the workpiece.

✅Automatic purge cycles flush the mixing valve with solvent or Component A to prevent internal curing during downtime
