Embodiment Construction

[0012] The device of the present invention will be described in further detail below in conjunction with the accompanying drawings.

[0013] Such as figure 1 As shown, a monitoring device for laser wet cleaning of carbon fiber resin-based aviation composite materials, including a laser cleaning system, a control and detection system, and a water supply system. The laser cleaning system is composed of a laser, a lens cabin, a laser controller, a lens, and a host computer. The center of laser device 4 and concave lens 6, convex lens 7 and lens 8 in the lens group is located on the same straight line. The lens group diffuses the laser beam with parameters adjusted by the host computer 1 and the laser controller 2 to increase the coverage area, and then passes through the concave lens 6, the convex lens 7, and the lens 8, and then focuses it into a spot arrangement that meets the requirements for cleaning the material surface, and acts on the laser beam to be treated. Clean the ...

Abstract

The invention relates to a monitoring device and method for laser wet cleaning carbon fiber resin-based composite materials, including a mobile platform, a reaction chamber is fixed on the mobile platform, a carbon fiber resin-based composite material is fixed in the reaction chamber, and the carbon fiber resin A laser cleaning system is arranged above the matrix composite material, and a water inlet and a water outlet are provided on the reaction chamber, the water inlet is connected to a water inlet pipe, the water outlet is connected to a water delivery pipe, and a nozzle is installed on the water inlet, The nozzle is facing the surface to be cleaned of the carbon fiber resin-based composite material, and a water quality sensor is arranged in the reaction chamber, and the water quality sensor is connected to a water quality detector. The invention uses a multi-purpose replaceable lens to reasonably focus and arrange the laser, effectively meeting the coexistence of large-area cleaning and local precision cleaning in the cleaning of aviation materials, and is also suitable for cleaning high-value aviation precision materials while ensuring efficiency.

Description

technical field [0001] The invention belongs to the technical field of laser cleaning, in particular to a device and method for real-time monitoring laser wet cleaning of carbon fiber resin-based aviation composite materials. Background technique [0002] Laser cleaning is considered to be a new type of cleaning method with great potential due to its non-contact, non-secondary pollution and ability to clean submicron particles. Laser wet cleaning is to cover the workpiece with a liquid film. The laser can be irradiated on the liquid film by adjusting the focus or directly acting between the material and the liquid film to achieve different cleaning intensities to meet different needs. As the most widely used high-performance composite material in the aviation industry, carbon fiber resin-based materials will not generate oxidized impurities like traditional metal materials in a water environment, and are suitable materials for wet laser cleaning. However, there is a lack of...
