Description

Technical Field

[0001] The utility model relates to the technical field of laser cleaning equipment, in particular to a handheld head of a laser cleaning machine. Background Art

[0002] The handheld laser cleaning machine includes a laser generator installed inside the laser cleaning machine, a cable connected to the laser generator, and a handheld head connected to the end of the cable for emitting laser. Its principle is to generate a high-energy laser beam through the built-in laser generator, which is focused and irradiated to the surface of the object, so that the dirt or rust layer on the surface of the object quickly heats up and evaporates. At the same time, the shock wave generated peels off the dirt or rust layer from the surface of the object, thereby achieving efficient and precise cleaning effects. Since the entire process adopts non-contact operation, mechanical damage to the object is avoided, and no chemical solvents are required. It is environmentally friendly and safe, so it is widely used in cleaning operations in the industrial manufacturing field.

[0003] However, in actual use, due to the certain distance between the handheld head and the object to be cleaned, it is difficult for workers to accurately aim at the area to be cleaned during the laser cleaning operation, and it is difficult to lock the focal length of the laser cleaning. Especially when cleaning specific small or complex areas on the surface of the object, it is easy for the normal part of the object surface to be damaged due to the deviation of the cleaning position or the cleaning effect to be poor due to the inability to lock the focal length of the laser cleaning. In addition, since there are other impurities and dust above the rust layer of the object to be cleaned, if laser cleaning is performed directly, the dust will diffuse in the air and affect the laser beam, reducing the cleaning efficiency of the laser cleaning operation.

[0004] In view of this, the inventor conducted in-depth research on the above-mentioned issues, which led to the creation of this case. Utility Model Content
