LED Module Epoxy Resin Potting Machine

Mixing and Dispensing Process
Compound materials A and B are stored in two separate tanks. Inside the machine, there are two sets of precision metering pumps. These pumps are designed to accurately meter the A and B resins according to a pre - set ratio. Each pump draws the respective material from tank A and tank B independently. Once the materials are pumped out, liquid A and liquid B are introduced into a mixer pipe. Inside the mixer pipe, they are thoroughly mixed to achieve a homogeneous blend. The mixed material is then dispensed out based on the programmable data, ensuring precise and consistent application.
Tank System Technology Features
1. Vacuum - Resistant Stainless Steel Panel Tanks
The tanks are constructed with stainless steel panels, specifically engineered to withstand negative pressure within the inner tank. This design feature is crucial for processes that require vacuum - assisted operations, such as degassing or material transfer.
2. Motor - Driven Stirring Mechanism
Each tank is equipped with a motor - driven stirrer. The stirrer continuously agitates the glue inside the tank, preventing sedimentation of the components. Additionally, it helps in maintaining a constant temperature of the potting material, ensuring uniform viscosity and quality throughout the dispensing process.
3. Liquid Level Sensing and Alarm System
The tanks are fitted with top, high, and low liquid sensors. These sensors continuously monitor the liquid level in the tank. When the liquid level rises above the high - level setting or drops below the low - level setting, an alarm is triggered. This early warning system allows operators to take timely action, such as refilling or adjusting the dispensing process.
4. Vacuum Degassing Function
The tanks are equipped with a vacuum degassing system. The degassing time can be conveniently set through the touch - screen interface. By applying vacuum negative pressure, the system effectively removes air bubbles and other volatile components from the material. After degassing, the material can be re - fed into the system, ensuring a high - quality, bubble - free output.
5. Pressure Release and Back - Flow Control
Each tank is fitted with a pressure - releasing ball valve. This valve allows for the safe release of excess pressure within the tank. At the bottom of the tank, a back - flow connector and a river closure ball valve are reserved. These components provide a reliable way to control the flow of material, especially during maintenance or when preventing back - flow of the compound.
6. Material Pre - heating System
A heater is integrated into each tank. The heater can pre - heat the materials to an optimal temperature, which is essential for ensuring good flowability. By maintaining the material at the right temperature, the dispensing process becomes more efficient and the quality of the final product is improved.
7. Manual Feeding Option
The tanks are equipped with an artificial feeding mouth. This feature allows operators to add glue to the tank manually when necessary. It provides flexibility in the operation, especially during start - up, small - scale production, or when quick adjustments are needed.
8. Silica - Dryer for Material Protection
To prevent the material, especially PU (Polyurethane), from crystallization, each tank is equipped with a silica - dryer. The silica - dryer absorbs moisture from the surrounding environment, keeping the material in a stable state and ensuring its long - term usability.

1. Automatic Tank Loading
The system is equipped with an automatic loading mechanism that efficiently transfers resin and hardener from their respective barrels. This automated process not only streamlines operations but also reduces the risk of human - error and contamination during the material transfer, ensuring a consistent and reliable supply of materials for the dispensing process.
2. Servomotor - Controlled Precision Movement
Featuring a servomotor - controlled design, the equipment guarantees smooth acceleration and deceleration. The servomotor technology enables highly precise movement, eliminating any jerks or sudden stops. This precision is crucial for accurate dosing and application, especially when dealing with intricate patterns or small - scale components. It ensures that the dispensing process is carried out with the utmost accuracy and repeatability.
3. High - Low Material Quantity Level Sensors
The tanks are outfitted with advanced high - low material quantity level sensors. These sensors continuously monitor the material levels in the tanks, providing real - time feedback. When the material reaches the pre - set high or low levels, an alarm or notification can be triggered, allowing operators to take timely action such as refilling or adjusting the production process. This feature enhances the system's reliability and prevents production interruptions due to material shortages or over - filling.
4. Automatic Dosing for Operator Convenience
The automatic dosing feature is a significant advantage for operators. It allows them to take breaks during the production process without compromising the quality and consistency of the output. Once the dosing parameters are set, the machine can operate independently for a period, maintaining the correct ratio of resin to hardener. This not only improves operator comfort but also increases overall productivity by reducing the need for constant supervision.
5. Memory for 999 Different Loading Programs
The system has the capacity to memorize up to 99 different loading programs. This flexibility enables quick adaptation to various production requirements. Whether it's a change in the product design, material type, or dosing quantity, operators can simply select the appropriate pre - programmed setting from the memory. This saves time on reprogramming and ensures that the machine can quickly switch between different production tasks with minimal downtime.
6. Precise Setting of Dosing Quantity and Speed on 7 - Inch Touch Screen
The 7 - inch touch screen interface provides an intuitive and user - friendly way to set the dosing quantity and speed. Even for the smallest amounts, operators can precisely configure these parameters. The high - resolution touch screen allows for easy navigation and adjustment, ensuring that the machine can meet the most demanding production specifications. This level of control is essential for achieving consistent and high - quality results.
7. Easy and Fast Programming with Joystick
The inclusion of a joystick for programming offers a convenient and efficient way to operate the machine. With the joystick, operators can quickly and accurately input commands, adjust settings, and create or modify dispensing programs. This hands - on control method simplifies the programming process, reducing the learning curve for new operators and enabling faster setup times between different production runs.
8. Static Mixer and Equipment Cleaning Function
After each operation, the system is equipped with a static mixer or dynamic cleaning equipment. This function is designed to prevent the waste of static/dynamic mixers by thoroughly cleaning them. By maintaining the cleanliness of the mixers, the system ensures that subsequent production runs are not affected by residual materials, which could lead to inconsistent mixing ratios or clogging. This not only saves on material costs but also extends the lifespan of the mixing components.
9. Integrated Heating Systems
The resin tank, metering pump, and resin tube are all equipped with heaters. These heaters play a crucial role in maintaining the optimal temperature of the resin. By keeping the resin at a consistent temperature, its viscosity remains stable, ensuring smooth flow and accurate dosing. This is particularly important for materials that are sensitive to temperature changes, as it helps to achieve better mixing and application results.
