High precision ultrasonic spraying machine

2.1.1 The nozzle section utilizes ultrasonic high-frequency oscillation to atomize the liquid into uniform micro and nanoscale particles, reducing the requirement for nozzle aperture and reducing the risk of nozzle blockage.

The 2.1.2 system provides multi-level adjustable ultrasonic power, which can improve the uniformity of liquid particle distribution and further improve the uniformity of the coating after spraying.

2.1.3 High precision ultrasonic nozzles can achieve extremely low stable flow rates, thus achieving minimal loading on the substrate to obtain thinner thin film coatings.

2.1.4 The ultrasonic nozzle has no pressure effect on the liquid, and uses a high-precision metering pump to control the flow rate of atomized coating liquid, thereby achieving high-precision spraying flow control.

2.1.5 High precision delivery pumps made of polypropylene or polyethylene, combined with micro flow channel design of ultrasonic nozzles, can achieve overall control accuracy of micro liters per second, in order to ensure that the system has good control ability of material loading on the substrate per unit time.

2.1.6 The ultrasonic nozzle only requires a small air volume of kilopascals, and during its spraying process, there is almost no liquid rebound or splashing, increasing the coating utilization rate to over 90%.

Under the action of air convection, atomized droplets usually scatter and drift, and the interference of air is reduced through a guiding device to achieve directional focusing and achieve the desired coating effect.

In order to ensure the stable flow rate of liquid delivery within the set working range, we independently developed a liquid delivery pump, solution pipeline, nozzle delivery system, and a three-dimensional high-precision transmission module.

The three-dimensional transmission module of 2.1.9 uses PLC as the system control core, and achieves the movement of the nozzle in a certain three-dimensional space by controlling the stepper motor and stepper motor driver under the precision manufacturing of the polished rod and synchronous belt.

2.1.10 The conveying device is controlled by a high-precision driver to adjust the movement speed of the nozzle.
