V-KOOL Laser Protective Lens Ultrasonic Cleaning Machine

VGT-1309FS Ultrasonic Cleaner Technical Analysis:

In high-end laser processing and optical systems, the cleanliness of protective lenses directly determines the operational efficiency and lifespan of the equipment. To meet this precision requirement, the Weigute VGT-1309FS ultrasonic cleaner provides an industrial cleaning solution for laser protective lenses through its 13-tank modular design and centrifugal drying technology, making it a critical pre-treatment device for optical coating.

I. Core Technology: Engineering Implementation of Precision Cleaning:

1. Multi-Tank Collaborative Cleaning System:

The equipment adopts a 13-station tank layout, covering the entire process of cleaning, rinsing, slow-pull dehydration, and centrifugal drying. The modular structure allows for flexible disassembly and combination based on process requirements. For example, for pre-coating cleaning of laser lenses, aqueous cleaning agent tanks and high-purity water rinsing tanks can be configured to effectively remove dust, polishing powder, and organic residues. The rinsing tanks are equipped with ultrasonic cavitation and temperature control systems, combined with multi-layer filtration devices, ensuring no cleaning agent residue and meeting optical-grade cleanliness standards.

2. Dynamic Cleaning Enhancement Technology:

Sweep Frequency Ultrasonics: Utilizes IGBT control technology to achieve sweep frequency output, with power continuously adjustable from 40% to 99%, avoiding cleaning blind spots caused by fixed frequencies while protecting the lens coating.

Mechanical Agitation: Drives the cleaning basket to move up and down at high frequency (adjustable agitation amplitude) via a lead screw transmission mechanism, increasing the shear force between the lens surface and the liquid, accelerating the removal of deep-hole and edge contaminants.

3.Intelligent Control and Drying Innovation:

The touchscreen human-machine interface supports preset and storage of multiple sets of cleaning process parameters (e.g., adjustable time from 2 to 20 minutes). After cleaning, the robotic arm automatically grabs the material basket and transfers it to the centrifugal drying station. An optional clean hot air buffer station enables "zero-contact" drying, eliminating secondary contamination.

II. Key Points for Safe Operation and Precise Control:

1. Standardized Startup and Shutdown Procedures:

Before startup, ensure the liquid level in the tank reaches 1/2 to 3/4 of the tank depth; no-load startup is strictly prohibited. Neutral aqueous solvents are recommended for the cleaning solution, with a temperature ≤80°C. Continuous operation should not exceed 4 hours. Before shutdown, set the power knob to zero, allow a 3-6 minute delay for heat dissipation, and then turn off the power.

2. Adaptive Parameter Adjustment:
For Laser Lens Characteristics:

Time: Set based on the degree of contamination (typically 3-10 minutes); excessive time may damage microstructures.

Power: Initially set to medium (approximately 60%), with stepwise increases for stubborn contaminants.

Temperature: 40°C-60°C can enhance cleaning agent activity but must match the heat resistance of the lens substrate.

3.Safety Protection Design:

The equipment is equipped with dual photoelectric protection switches and an emergency stop button. The handling mechanism features shock absorption design (lateral speed ≤120mm/s) to prevent lens collisions. The electrical control system complies with IP54 protection rating, with mandatory grounding terminal connection to prevent induced current damage to workpieces.

III. Maintenance Strategy: Ensuring Long-Term Stable Operation

Daily Maintenance: Drain contaminated cleaning solution after work, rinse filters and nozzles to prevent particle accumulation.

Monthly Maintenance: Check the condition of bearing lubricant, apply calcium-based lubricant to the transmission lead screw, and test the output stability of the ultrasonic generator.

Water Quality Monitoring: Use the built-in resistivity meter to monitor pure water resistivity in real-time (>15MΩ·cm), ensuring no ion residue during the rinsing stage.

Fault Prevention Tips: If ultrasonic intensity decreases or abnormal noise occurs, it may indicate transducer scaling or generator malfunction. Immediately stop the machine and clean the transducer surface.

The Weigute VGT-1309FS addresses the challenge of micro-residues on laser protective lenses through its engineering-grade cleaning architecture and optical process adaptability. Its value lies not only in cleaning efficiency (shortest cycle time of 2 minutes) but also in ensuring coating yield through monitorable process consistency. For high-precision applications such as kilowatt-level laser equipment, this type of device has become a core pre-treatment safeguard to avoid lens thermal lensing effects and improve beam quality.
