The key points of the technical scheme are: a holding handle, the two ends of the holding handle are respectively connected with an isolation head and a cleaning head, and the isolation head is connected with an optical fiber Connector, the gripping handle is provided with a reflector, and the gripping handle is provided with an adjustment piece, the cleaning head includes a connecting barrel, a lens barrel slidingly arranged in the connecting barrel, and a lens barrel arranged at one end of the lens barrel A focusing mirror, the connecting cylinder is provided with a drive mechanism, one end of the connecting cylinder is provided with a distance sensor, the distance sensor is connected to a controller, and a collimating mirror is also provided in the lens barrel, and the focusing mirror includes A central focusing mirror and several adjustable focusing mirrors located on the peripheral side of the central focusing mirror, the end of the lens barrel is provided with an adjustment mechanism. The invention can automatically control the cleaning distance, increase the cleaning range, avoid gaps in the connection during the cleaning process, and has the advantage of improving the cleaning effect.

Description

technical field [0001] The invention relates to the technical field of laser cleaning, and more particularly, to a laser cleaning head. Background technique [0002] Laser cleaning is an efficient and green cleaning technology. Compared with chemical cleaning and mechanical cleaning, it has certain advantages. It does not require any chemical reagents, no grinding, no stress, no consumables, less damage to the substrate, and high cleanliness. advantage. In the current laser cleaning system, the laser in the laser processing head passes through the laser mirror and is focused by the focusing mirror to act on the surface of the cleaning sample. [0003] For example, the Chinese patent with the authorization announcement number CN210754166U and the announcement date of 2020.06.16 discloses a laser cleaning head, including a holding handle, the front end of the holding handle is fixedly connected with a laser isolator, and the front end of the laser isolator is A fiber optic c...

Problems solved by technology

However, in the process of use, workers need to be able to accurately find the distance between the focusing lens and the cleaning surface in the handheld laser cleaner to ensure the quality of the laser cleaning surface. In actual use, the cleaning surface is mostly uneven. On the surface, workers are required to be able to accurately adjust the distance between the laser cleaner and the cleaning surface, but inaccurate artificial control of the distance will lead to uneven cleaning, poor cleaning effect, and only a small spot can be formed after the laser is focused. The range is narrow, and there will be small gaps in the cleaning connection that are not easy to control, resulting in poor overall cleaning effect
