In modern precision electronics, new energy, and automotive manufacturing, sealing and potting processes directly determine a product's lifespan and operational reliability. As manufacturing demands grow increasingly complex, traditional manual or semi-automatic dispensing methods can no longer meet the standards of high precision and efficiency. Epoxy automatic sealing equipment has emerged as a vital solution. It is not only a core component of automated production lines but also a crucial tool for enterprises to reduce costs, increase efficiency, and improve product yield rates.
The potting and sealing of small electronic components demand exceptionally high precision from equipment. Our epoxy automatic sealing equipment is specifically designed to meet these rigorous requirements, completely eliminating issues associated with traditional manual dispensing, such as uneven thickness, glue overflow, and stringing.
Micron-Level Motion Precision:
Equipped with an advanced three-axis linkage system and servo motor drive, the equipment achieves a motion precision of ±0.02mm. Whether targeting extremely fine PCB edges or tiny chip pins, the machine accurately executes dots, lines, arcs, and irregular trajectories, ensuring perfect adhesive alignment.
High-Precision Fluid Metering:
Built-in high-precision, wear-resistant piston or gear pumps, combined with intelligent PLC control, allow for automatic ratio adjustment from 1:1 to 1:20. Both the mixing ratio and dispensing precision are strictly controlled within ±1%. This means absolute consistency is maintained, even for ultra-small dispensing volumes.
Intelligent Anti-Stringing & Vacuum Suck-Back:
To address the common issues of glue stringing and dripping on tiny components, the equipment features a vacuum suck-back function. It instantly retracts the adhesive the moment dispensing ends, ensuring clean and precise glue dots, which significantly improves the aesthetic yield rate of the products.
Small electronic components are often deployed in extremely complex operating environments. Our equipment goes beyond merely "applying" adhesive; it is dedicated to enhancing overall product performance:
Bubble-Free Vacuum Potting:
For high-voltage, high-precision micro-components (such as micro-transformers and sensors), the equipment can be equipped with a vacuum potting chamber. Operating at a vacuum level of -99kPa, the adhesive penetrates deeply into the microscopic gaps within the components, thoroughly exhausting air. The cured surface is smooth and free of pinholes, greatly enhancing the product's dielectric strength, moisture resistance, and shockproof performance.
Constant Temperature Control & Leveling:
For high-viscosity epoxy resins, the equipment provides precise adhesive heating and pipeline insulation (adjustable from room temperature to 80°C). This effectively reduces adhesive viscosity, ensuring excellent fluidity and adhesion within confined micro-spaces.
COB Packaging & Black Glue Protection:
For IC chips, gold/aluminum wires, and solder joints, the equipment can precisely apply black epoxy resin to form a robust protective layer, effectively preventing oxidation, corrosion, and mechanical damage.
From consumer electronics to automotive electronics, our epoxy automatic sealing equipment is providing an "invisible armor" for small components across various industries:
Consumer Electronics: TWS earphone battery fixation, mobile phone button and housing bonding, Type-C interface waterproof sealing, and potting for micro-speakers and microphones.
Automotive Electronics: Tire pressure sensor sealing, parking radar module potting, ECU control board moisture protection, and micro-car light LED array dispensing.
Power & Telecommunications: Insulation sealing for micro-transformers, inductors, relays, lightning protection modules, and various fiber optic communication devices.
In the manufacturing of small electronic components, time is profit, and yield rate is paramount. Our epoxy automatic sealing equipment supports one-click program recall, automatic mixing tube cleaning, and intelligent low-material alarms, drastically reducing manual intervention costs and scrap rates. Whether for standalone operation or seamless integration into fully automated production lines, we can provide customized fluid control solutions tailored to your needs.
