There are various methods for cleaning Juki SMT nozzles due to the rapid development of the electronics manufacturing industry, which demands increasingly smaller components. While larger nozzles can still be cleaned using industrial alcohol and needle-through-hole methods, the shrinking size of components poses challenges for cleaning, with some nozzles having internal diameters as small as a few micrometers. When blockages occur, they often result in complete nozzle replacement. Despite the high precision of SMT placement machines, cleanliness of the nozzles remains a critical factor affecting performance.
Traditional Cleaning Methods:
- Needle-through-hole method: Inserting a steel needle through the nozzle orifice. However, this risks damaging the nozzle, especially if the internal passage is not fully clear.
- Industrial alcohol + hot air gun: Using a soft cloth soaked in industrial alcohol for wiping followed by hot air blowing. However, this method is labor-intensive and cannot clean the nozzle’s internal passages, risking damage to reflective plates if alcohol seeps into adhesive layers.
- Ultrasonic cleaning machine: While relatively common, many SMT machine manufacturers explicitly prohibit this method due to the risk of damaging the crucial black coating on the nozzle surface through mutual collision and potential detachment of reflective plates.
Automatic Nozzle Cleaning Machine:
- This machine features unique mechanical and pneumatic design, utilizing a built-in high-pressure liquid storage device to atomize water into fine mist with high pressure, generating powerful kinetic energy to dislodge dirt on both the surface and inside the nozzles.
- Cleaning agent: Industrial deionized water, environmentally friendly and harmless to nozzles, complying with environmental regulations.
- Cleaning efficiency: Capable of simultaneously cleaning 40 Juki SMT nozzles each time, with automated cleaning settings to save labor.
- Applicability: Suitable for all models of SMT placement machines.
