However, residues remaining inside the stencil can affect the printing accuracy and quality of the stencil, thus requiring a cleaning machine to quickly remove various residues from the stencil and restore its good performance.
[0003] Existing cleaning machines have filters installed in the water circulation system. After long-term use, these filters need to be replaced. However, the filters are located inside the spray drying tank, making replacement difficult and prone to falling into the tank, increasing the complexity of the process. Therefore, a steel mesh cleaning machine is needed to quickly and reliably remove the filters from the spray drying tank for replacement, with simple operation. Utility Model Content
[0004] The purpose of this utility model is to provide a steel mesh cleaning machine to solve the problem mentioned in the background art, where existing cleaning machines have a filter screen installed in the water circulation system during actual use. After long-term use, the filter screen needs to be replaced. However, the filter screen is located inside the spray drying tank. When replacing the filter screen, it is not only difficult to replace the filter screen, but the filter screen is also easy to fall into the spray drying tank, which increases the difficulty of replacing the filter screen.
[0005] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution:
[0006] This utility model is a steel mesh cleaning machine, comprising:

[0016] II. Based on the first beneficial effect, when the stencil needs cleaning, with the help of the cleaning components, the stencil with solder paste is first placed in the stencil basket. After setting the cleaning parameters through the control panel, the equipment is started. The moving arm transfers the stencil basket into the ultrasonic cleaning tank. The ultrasonic generator is activated, generating high-frequency vibrations in the solvent. The cavitation effect is used to peel off the solder paste from the stencil holes. The solvent circulation system works simultaneously to filter and recover impurities in the solvent, extending the solvent's lifespan. After cleaning, the moving arm moves the stencil basket into the spray drying tank. The spray system performs a fine rinse on the stencil, and the built-in water jet and air knife further dry the stencil, ensuring no moisture residue. During this process, the forced exhaust fan runs continuously to remove moisture and volatile gases, maintaining environmental safety. Finally, the cleanliness of the stencil is manually checked. After confirmation of its quality, it is transferred to the SMT production line. This solution can efficiently clean the stencil. Attached Figure Description
