During the production or maintenance of PLC optical fiber splitters, there are indeed situations where certain accessories may need to be cleaned with an ultrasonic cleaner. The following are typical accessories that require ultrasonic cleaning and precautions:

1. Optical fiber adapters (such as LC/SC/FC, etc.) :

Metal or ceramic sleeves may be contaminated with dust and oil stains. Ultrasonic cleaning can effectively remove contaminants and ensure the accuracy of optical fiber docking.

2. Ceramic Ferrule:

Ceramic ferrules used in optical fiber connectors have extremely high requirements for cleanliness, and ultrasonic waves can remove micron-sized particles.

3. Splitter Chip (PLC Chip)：

Before packaging or during maintenance, the surface of the chip must be free of dust and static electricity. Ultrasonic waves combined with dedicated solvents (such as IPA) can safely clean it.

4. Metal casing or structural components:

If there are metal shavings or grease residues from precision processing, ultrasonic cleaning is more thorough than manual cleaning.

Advantages of ultrasonic cleaning machines:

1. Highly efficient decontamination: It has a better cleaning effect on complex structures (such as the inner holes of adapters) than manual cleaning.

2. Non-contact type: Avoids physical scratching and damage to precision surfaces (such as ceramics).

3. Consistency: Suitable for batch processing, it improves production efficiency.

The Weigute ultrasonic cleaning machine manufacturer reminds you of the precautions for cleaning PLC optical fiber splitters:

1. Frequency selection:

For precision components (such as ceramic ferrule cores), it is recommended to use high frequencies (above 40kHz) to avoid cavitation corrosion caused by low frequencies.

2. Selection of cleaning solution:

Ceramic/glass material: Use deionized water or alcohol (IPA).

Metal parts: Neutral cleaning agents can be added to prevent corrosion.

Do not use strong acids or strong alkalis to prevent damage to the optical coating of the PLC splitter.

3. Time control:

It usually takes 3 to 5 minutes. If it lasts too long, it may cause the components to loosen (such as at the bonding points) or develop microcracks.

4. Drying steps:

After cleaning, it should be blown dry with dust-free nitrogen or dried at low temperature to avoid water stains remaining.

The VGT-1409FH from Weigute is a 14-tank fully automatic high-end ultrasonic cleaning system, suitable for deep cleaning in fields such as precision optics, PLC optical fiber splitters, and semiconductors.

Core configuration:

1.Number of tanks: 14 fully automatic production lines (customizable tank position functions available).

2. Ultrasonic frequency:

Multiple frequencies are available (28KHZ/40KHZ/80KHZ/120KHZ), and different slots can be set independently.

3. Cleaning medium: Supports deionized water, IPA (isoacetone), and optic-grade cleaning agents.

4. Heating system: Constant temperature control (RT ~ 90℃), and some tank positions can be cleaned at high temperatures.

5. Transmission method: Mechanical arm/chain conveyor (with slow lifting function to prevent water stain residue).

6. Filtration system: 0.1μm precision filtration + circulation system to ensure the cleanliness of the cleaning solution.

7. Drying system: PLC+ touch screen (capable of storing over 100 sets of cleaning programs and supporting remote monitoring).

8. Cleanliness: Class 100-1000 dust-free adaptation is available.

9. Production capacity: 500- 2,000 pieces per hour (depending on the cycle time).

More efficient drying and anti-pollution design:

IPA steam + hot air + vacuum three-stage drying: First, the moisture is replaced by IPA (isopropyl alcohol) steam, then dried with hot air at 80℃, and finally vacuum drying can be selected to ensure zero water residue.

Anti-static + dust-free design: The equipment material is made of anti-static PP/ stainless steel, and the conveyor belt is equipped with ion air rods to prevent dust adhesion.

Industry-specific optimization (for PLC optical fiber splitters) :

Ceramic Ferrule special fixture: To prevent ferrule collisions during the cleaning process and ensure zero scratches on the end face.

PLC Chip protection mode: Low frequency + short-term cleaning (such as 40kHz/1 minute) is adopted to prevent the cracking of the adhesive layer.

Metal casing grease removal optimization: For the aluminum alloy casing of the splitter, a 60℃+ alkaline cleaning agent tank is set up to efficiently remove grease.

The VGT-1409FH of Weigot (or similar 14-slot equipment) may also be equipped with high-end functions such as intelligent control, megabonic/vacuum cleaning, three-stage drying, anti-static design, and modular expansion, further meeting the strict cleaning requirements of PLC optical fiber splitters, semiconductors, and optical components.
