Description

Technical Field

[0001] The utility model relates to the technical field of laser cleaning, in particular to an automated device for removing paint from the surface of NdFeB magnets by using pulse laser. Background Art

[0002] During the production process, the surface of NdFeB magnets is often painted to protect it from corrosion and oxidation. However, during subsequent processing or use, the painted magnet surface may need to be cleaned to remove the unwanted paint layer. This is especially important when the paint position is incorrect or needs to be adjusted.

[0003] Traditional methods for cleaning the surface of NdFeB magnets after spraying paint often rely on chemical or mechanical cleaning. While these methods can meet cleaning requirements to a certain extent, they have many shortcomings. For example, chemical cleaning methods require large amounts of chemical reagents, which is not only costly but also harmful to the environment and operators. Mechanical cleaning methods, while less expensive, are inefficient and prone to damage to the magnet surface. Laser cleaning utilizes a high-energy laser beam to illuminate the material surface, rapidly vaporizing or stripping away surface contaminants, thereby achieving the purpose of surface cleaning. Compared with traditional cleaning methods, laser cleaning offers advantages such as high safety, good environmental performance, non-contact operation, no consumables, and high precision, making it particularly suitable for high-precision and demanding cleaning applications.

[0004] In the existing technology, there are few laser cleaning devices on the market for cleaning the paint spraying on the surface of NdFeB magnets, and most of the devices still have shortcomings in cleaning efficiency and positioning accuracy, which is not conducive to practical use.

[0008] Preferably, an adjusting jig is provided in sliding connection with the surface of the linear motor guide rail, and the adjusting jig abuts against the surface of the workpiece body.

[0009] Preferably, a control panel is bolted onto the outside of the laser cleaning station, and the control panel is electrically connected to the first linear guide rail and the second linear guide rail.

[0010] Preferably, the surface of the linear motor guide rail is bolted to the surface of the load-bearing processing table, and the engagement position between the adjustment fixture and the linear motor guide rail is an I-shaped groove.
