What is the working principle of a screen cleaning machine? I believe many new users have this question. Silman Tech’s fully automatic screen cleaning machine can efficiently clean screen plates (copper plates) with solder paste or red glue without causing damage to the screen plates. Considering that the automatic screen cleaning machine adopts ultrasonic cleaning technology and is equipped with a spray device, the dual effect of ultrasonic waves and automatic spraying system can effectively high-pressure wash the solder paste on the screen plates. It also automatically dries the plates without leaving watermarks on them. Even wiping the screen plates gently with a clean white cloth reveals no residues or dust on the cloth, indicating that the cleaning effect of the machine is reliable!
Die Siebreinigungsmaschine employs three cleaning process technologies: solvent cleaning, ultrasonic immersion, and air knife drying. In the first process, the screen plate is clamped by the pre-assembled internal structure of the fully automatic screen cleaning machine and automatically controlled to move back and forth slowly to ensure that every part is properly sprayed and cleaned. Under the action of ultrasonic waves, the cleaning solvent generates tens of thousands of cavitation bubbles, which burst rapidly under positive pressure, producing a type of shock energy that can quickly remove the solder paste and red glue adhering to the screen plates. Combined with a high-pressure automatic spraying system, this ensures thorough cleaning of the entire screen.
The second cleaning process technology is ultrasonic immersion. Although the first ultrasonic spray cleaning achieves excellent cleaning results, as it uses chemical cleaning agents, immersion of the screen plates is necessary. This step uses water as the medium, with an ultrasonic frequency of 40 kHz and a liquid temperature of approximately 40 degrees Celsius. After immersion, the fully automatic screen cleaning machine proceeds to the third process technology, air knife drying, which removes the water stains from the second process. In fact, the operation of all cleaning steps is simple. The operator only needs to place the screen plates on the mechanical arm of the screen cleaning machine and press the start button. The machine’s mechanical arm will then transport the screen plates to the designated process according to the sequence set by the technical engineer for each step of the cleaning process, before returning them to their original position to complete all the cleaning steps.
The screen cleaning machine uses a water-based solvent, which has many advantages compared to organic solvents. Organic solvents cannot be reused multiple times, while water-based solvents can be reused, saving solvent costs. Organic solvents are volatile liquids that evaporate easily, while water-based solvents do not evaporate as quickly. Additionally, organic solvents carry more ions compared to water-based solvents. If organic solvents are used for cleaning, the cost would be approximately 8 to 10 yuan per plate, while using water-based solvents would reduce the cost by 50%.
Above is the introduction to the working principle of the screen cleaning machine. I hope this helps you. If you have any questions, you can consult Silman Tech, the manufacturer of screen cleaning machines, online for more information.
