Cleaning device and method for cleaning a surface

Simple SummaryContent extracted from patent full text and abstract with AI.

This patent describes a cleaning device and method for precisely cleaning surfaces using laser-induced single-bubble cavitation. The device channels a laser beam through an optical fiber into a chamber containing cleaning fluid, where the laser energy creates controlled individual bubbles. These bubbles collapse near the target surface, generating fluid microflows that remove contaminants without direct mechanical or harsh chemical action. The system allows precise adjustment of cleaning parameters, such as bubble size and location, to optimize cleaning efficiency and surface safety.

Use CasesContent extracted from patent full text and abstract with AI.

• Cleaning semiconductor wafers during chip fabrication processes
• Cleaning high-precision medical devices and surgical instruments
• Pre-cleaning or surface preparation for bonding or adhesive applications
• Removal of oily residues or fine particulate contaminants on precision mechanical components
• Industrial cleaning of process equipment in food, pharmaceutical, or other contamination-sensitive industries
• Delicate restoration or cleaning of optical glass, lenses, or other sensitive substrates

BenefitsContent extracted from patent full text and abstract with AI.

• Provides highly controlled and localized cleaning through precise bubble generation and placement
• Reduces risk of surface damage compared to traditional mechanical or ultrasonic cleaning methods
• Minimizes or eliminates the use of harsh chemicals, making the process more eco-friendly and easier to manage waste
• Adaptable to a wide range of surfaces, materials, and contaminant types, especially for small or sensitive components
• Portable and flexible design, allowing cleaning heads to be positioned independently of the main device
• Decreases maintenance needs and increases device robustness by leveraging fiber-optic delivery and standard infrared lasers
• Consistent and repeatable cleaning results, suitable for critical high-tech and industrial settings
