What is AB glue potting machine?

Based on common understanding in the market, An AB glue potting machine, also known as a two-component adhesive potting machine, is an automated system designed for mixing and dispensing two-part adhesives. These adhesives, such as epoxy, polyurethane, or silicone, consist of two separate components: a resin (Part A) and a hardener (Part B). The machine's primary function is to accurately measure, mix, and apply these components to a product. GDS automation offers various solution for AB glue or two parts glue potting application.

How it Works

The process is highly automated to ensure precision and consistency, which is crucial for the proper curing and performance of the adhesive. The general workflow includes:

Separate Storage: The two components, Part A and Part B, are stored in separate tanks within the machine. This prevents them from curing prematurely.

Precise Metering: The machine uses high-precision pumps (like screw pumps, gear pumps, or piston pumps) to draw the individual components from their tanks. It accurately measures them according to a pre-set ratio (e.g., 1:1, 10:1), which is essential for the chemical reaction to occur correctly.

Mixing: The metered components are then fed into a mixing device. This can be a static mixer, where the flow of the liquids causes them to mix, or a dynamic mixer, which uses a motor to stir them together. The mixing process ensures a uniform blend before application.

Dispensing: The mixed glue is then dispensed through a nozzle onto the product. This can be controlled by a robotic arm, which is programmed to follow a specific path for potting, or it can be a manual operation with a foot switch.

Automation and Control: The entire process is controlled by a system with a user-friendly interface, often a touch screen with a PLC (Programmable Logic Controller). This allows for setting parameters such as the mixing ratio, dispensing speed, and potting patterns. Many advanced machines also include features like vacuum degassing to remove bubbles from the glue and heating functions to control viscosity.

Applications

AB glue potting machines are widely used in various industries for a process called "potting" or "encapsulation." Potting involves completely embedding an electronic component or assembly in a liquid resin, which then cures to form a solid protective layer. This provides protection against:

Environmental factors: Moisture, dust, and corrosion.

Mechanical stress:Vibration and shock.

Electrical issues: Insulation and heat dissipation.

Common applications include:

Electronics: Potting of electronic coils, sensors, transformers, connectors, PCB boards, and power modules.

Automotive: Encapsulating components in car audio systems and other automotive electronics.

Lighting: Sealing and protecting LED drive circuits.

Other industries:Medical devices, telecommunications, and consumer products.
