Robot Arm Epoxy Potting Machine | Robotic AB Glue Dispensing System

The robot arm epoxy potting machine is an advanced robotic two-component AB glue automatic mixing and dispensing solution, integrating industrial robotic arm, servo metering system, glue mixing unit and automatic potting control software. Different from traditional 3-axis gantry dispensing machines, this robotic glue dispensing machine adopts 6-axis robot arm to realize flexible 3D motion, capable of potting on complex curved surfaces, inclined planes and multi-angle workpieces. It supports offline programming, fast program switching for different products, greatly reducing fixture cost for irregular parts.

This robotic potting system works with epoxy resin, PU and silicone two-component adhesives. The servo metering module delivers stable A/B glue ratio and consistent glue output volume. Equipped with anti-dripping valve and automatic cleaning function, it avoids glue dripping, wire drawing and pipeline blockage during continuous mass production.

Widely applied for current transformers, inductors, power modules, battery packs, automotive electronics and large electrical components. The robot arm epoxy dispensing system is ideal for workpieces requiring 3D multi-angle glue pouring, suitable for small batch customized production and fully automated assembly line integration.

FAQ

Q1: What adhesives does the robot arm epoxy potting machine support?

A: It works for two-component AB glue including epoxy resin, polyurethane(PU) and silicone. Glue ratio adjustable from 1:1 to 20:1, compatible with low viscosity to high viscosity filled resin.

Q2: What is the difference between robot arm potting machine and gantry dispensing machine?

A: The 6-axis robot arm realizes flexible 3D multi-angle dispensing, suitable for curved, inclined and irregular workpieces. Gantry machines mainly do planar 2D dispensing. Robotic system reduces fixture cost and supports fast product switching via offline programming.

Q3: Can this robotic dispensing machine work together with conveyor and vision positioning?

A: Yes. The robot arm epoxy potting system can integrate automatic conveyor, vision positioning, auto loading & unloading to form a fully automatic unmanned potting production line.

Q4: What is the dispensing accuracy of the servo metering system?

A: Dispensing volume accuracy ±1%. Robot repeat positioning accuracy up to ±0.03mm, ensuring consistent potting quality in mass production.

Q5: Does it support offline programming?

A: Yes. Two programming methods: teach pendant on-site teaching and offline programming software. Import pre-written programs directly when changing new products, shorten setup time.

Q6: Is automatic cleaning equipped?

A: Standard with automatic flushing system. It cleans mixing tube and dispensing valve after batch production, preventing residual glue curing and pipeline blockage. Anti-dripping valve comes as standard.

Q7: Can you customize the robot reach and glue flow rate?

A: Yes. We can select different robot working radius, adjust servo pump flow, safety enclosure and fixture design according to your workpiece size and production requirements.

Q8: Can the robotic potting machine combine with vacuum chamber for bubble-free potting?

A: Optional. We can integrate vacuum chamber on request, to realize vacuum bubble-free potting for products with strict requirement on zero bubbles.

Q9: What after-sales service do you provide?

A: We provide machine installation guidance, online training for programming and operation, spare parts supply and remote technical support. Overseas on-site service is negotiable.

Q10: What is the lead time?

A: Normally 30–45 working days, subject to machine configuration and customization items.
