Description

Technical Field

[0001] The utility model relates to the technical field of dust removal technology, in particular to dust removal for a camera lens. Background Art

[0002] For some AOI equipment inspection scenarios, it is necessary to use a line scan camera or an area array camera that is installed upside down with the photographing surface facing upwards. This will cause the lens to be covered with dust over time and will require manual cleaning at regular intervals.

[0003] Public document CN110913115A discloses a self-cleaning industrial camera box, including a casing, a lens board, a base, a cleaning mechanism and a power cord. The casing is sealed and slidably connected to the lens board via a slide bar, and a cylinder drives a scraper to move up and down along a slideway on the front end surface of the lens board through an output shaft. The scraping and washing method adopted in this structure is prone to damage components, and the water source delivery or spraying process is prone to contaminate the equipment, resulting in poor dust removal effect.

[0004] Public document CN216262468U discloses an electronic product cleaning device, which uses dust-removing silicone stickers, electrostatic adsorption metal sheets or panels with automatic humidification functions to perform dust removal operations. It includes steam channels, pressing sheets, springs and other supporting structures, is large in size and has a complex cleaning process. Utility Model Content
