Description

Technical Field

[0001] The utility model belongs to the field of guide rail cleaning, and particularly relates to a linear guide rail cleaning device. Background Art

[0002] In the field of mechanical manufacturing and automation, linear guides are precision mechanical parts with a wide range of applications, covering CNC machine tools, automation equipment, robots and other equipment. The accuracy and surface quality of linear guides directly determine the operating accuracy and service life of the equipment. Therefore, in the production process of linear guides, it is an important step to thoroughly clean the guides and remove impurities and dirt on the surface to ensure the quality and performance of the guides.

[0003] In the existing linear guide rail production process, the cleaning process mostly adopts manual or mechanical cleaning methods.

[0004] However, these methods have significant disadvantages:

[0005] 1. Manual cleaning: Although manual cleaning can clean the impurities on the surface of the guide rail in a relatively detailed manner, it is inefficient and cannot meet the needs of large-scale production. In addition, manual cleaning relies on the skills and experience of the operator, and cannot guarantee that the effect of each cleaning can meet the expected standards, resulting in unstable guide rail cleaning quality and difficulty in meeting the cleaning requirements of high-precision guide rails.

[0006] 2. Mechanical cleaning: Although mechanical cleaning improves the cleaning efficiency to a certain extent, the existing technology, such as the fully automatic cleaning and drying equipment for precision linear guides disclosed in publication number CN220005155U, has some problems in the cleaning process. During the linear guide conveying process of this equipment, the cleaning liquid sprayed by the spray cleaning machine will adhere to the surface of the guide, which reduces the friction between the linear guide and the conveying roller, causing the guide to slip during the conveying process. This not only affects the cleaning efficiency of the linear guide, but also because the slipping phenomenon may increase the relative movement between the guide and the conveying roller, thereby increasing the risk of scratching the surface of the guide, and further affecting the accuracy of the linear guide.
