In the field of precision optical device manufacturing and maintenance, the technical level of cleaning processes directly determines the performance and service life of optical components. The VGT-1109FH Weigute PC lens ultrasonic cleaning machine, as an industry benchmark product, has set a brand-new technical standard for high-precision lens cleaning through breakthrough innovations in multiple core technologies. This article will conduct an in-depth analysis of the five core technical systems of this device from dimensions such as technical principles, system architecture, and performance parameters.

1. High-frequency Ultrasonic Generation System: A Revolutionary Breakthrough in micron-level cleaning

The fourth-generation intelligent ultrasonic generator equipped in this device adopts all-digital DSP control technology, achieving a precise frequency output of 48kHz±5%. Through the patented frequency modulation pulse modulation technology (TFPM), the system can automatically match different dielectric impedances, ensuring that the transducer array always maintains an energy conversion efficiency of over 96%. Compared with the traditional fixed-frequency ultrasonic system, its cavitation bubble distribution density is increased by 40%, and the energy density per unit area reaches 2.3W/cm², which can effectively remove nano-particle contaminants at the 0.08μm level.

Ii. Intelligent Temperature Control and Fluid Dynamics System

The temperature control system adopts a dual-mode algorithm of PID+ fuzzy control, combined with a high-precision PT1000 platinum resistance sensor, to control the temperature fluctuation of the cleaning solution within ±0.3℃. The built-in 316L stainless steel heating module adopts a serpentine flow channel design, with a heat exchange efficiency of 92%. It only takes 78 seconds to raise the working temperature from room temperature to 80℃. The unique laminar flow circulation system (LCS) achieves a full liquid circulation of 12 times per minute in the tank through a centrifugal pump set, combined with the V-shaped deflector design at the bottom, ensuring the rapid discharge of pollutant particles.

In terms of solution management, the equipment integrates a TDS (Total Dissolved Solids) online monitoring system with a resolution of 1ppm. When the pollutant concentration exceeds the preset threshold, the system automatically initiates a three-stage filtration program: Firstly, large particles are intercepted through a 50μm stainless steel filter screen, then organic pollutants are adsorbed by molecular sieves, and finally fine filtration is completed through a 0.1μm ultrafiltration membrane. This closed-loop filtration system extends the service life of the cleaning solution to three times that of conventional equipment.

Iii. Multi-frequency Compound Cleaning Technology

Breaking through the technical limitations of traditional single-frequency ultrasonic waves, this device has achieved dynamic switching among the three frequency bands of 28kHz/68kHz/132kHz. In the first stage of the cleaning program, a 28kHz low frequency is used to generate powerful cavitation bubbles, effectively breaking down the contaminants with strong binding force at the edge of the lens. In the second stage, switch to the 68kHz intermediate frequency for deep cleaning of micron-level gaps. Ultimately, a nanoscale cavitation effect is generated through the 132kHz high-frequency band to completely remove the molecular-level contaminants adsorbed on the surface.

Iv. Innovation in Materials and Structural Design

The tank body is integrally cast from medical-grade SUS316L stainless steel and undergoes electrolytic polishing treatment to achieve a surface roughness of Ra≤0.1μm. The anti-corrosion titanium alloy transducer array adopts a honeycomb arrangement, with each unit equipped with an independent waterproof sealing structure. The IP68 protection level ensures stable operation in strong acid and strong alkali environments. The unique double-layer tank design reduces the structural vibration conduction loss to 0.3dB and effectively suppresses the formation of standing waves at the same time.

In terms of noise reduction, the equipment adopts A composite damping material sound insulation layer, combined with an active noise cancellation system (ANC), to keep the working noise below 52dB(A). The Class 0 air filtration system that complies with the ISO 8573-1 standard can effectively block particles with a particle size >0.01μm and meets the usage requirements of semiconductor cleanrooms (Class 100).

V. Environmental Adaptability Technology

The equipment is equipped with an altitude adaptive system. It adjusts the ultrasonic output power in real time through an atmospheric pressure sensor to ensure that the nominal cleaning efficiency can still be maintained at an altitude of 3,000 meters. The wide voltage input design (100-240V AC) combined with the PFC power factor correction module reduces energy consumption to 65% of similar products. The unique low-temperature start-up mode can operate normally in an environment of -20℃. The power density of the heating system reaches 8W/cm², ensuring rapid temperature rise under extremely cold conditions.

In terms of intelligent expansion, the equipment is equipped with an industrial-grade RS485 interface and EtherCAT communication protocol, which can be seamlessly integrated into the factory MES system. The cloud data management platform supports remote setting of cleaning parameters, process data traceability, and monitoring of equipment health status, enabling predictive maintenance. After third-party testing, the MTBF (Mean Time Between Failures) of the equipment reached 28,000 hours, and the annual failure rate was less than 0.5%.

Technology Empowers the future: A New Paradigm for Precision Cleaning

The technological innovation of the VGT-1109FH Weigute PC lens ultrasonic cleaning machine is not only reflected in the breakthrough of parameter indicators, but also in the establishment of a complete precision cleaning technology system. From the physical effects of high-frequency ultrasonic waves to the digital control of intelligent systems, from breakthroughs in materials engineering to the improvement of environmental adaptability, each technical module has undergone precise calculation and verification. In cutting-edge fields such as quantum optical devices, EUV lithography systems, and space telescopes, this technical solution that integrates mechanical engineering, materials science, and intelligent control is redefining the technical boundaries of precision cleaning and providing indispensable fundamental support for the high-end manufacturing sector.
