Linear guide cleaning device
Technical Field
The utility model belongs to the field of guide rail cleaning, and particularly relates to a linear guide rail cleaning device.
Background
In the fields of machine manufacturing and automation, linear guide rails are used as precision mechanical parts, and the linear guide rails have a wide application range and cover various devices such as numerical control machine tools, automation devices and robots. The accuracy and surface quality of the linear guide rail directly determine the operation accuracy and service life of the equipment. Therefore, in the production process of the linear guide rail, the guide rail is thoroughly cleaned, and impurities and dirt on the surface are removed, so that the method is an important step for ensuring the quality and performance of the guide rail.
In the existing linear guide rail production process, a manual or mechanical cleaning method is mostly adopted in the cleaning link.
However, these methods have significant drawbacks:
1. Manual cleaning, namely, although the manual cleaning can carefully clean impurities on the surface of the guide rail, the efficiency is low, and the requirement of mass production cannot be met. In addition, manual cleaning depends on the technology and experience of operators, and the effect of each cleaning can not reach the expected standard, so that the cleaning quality of the guide rail is unstable, and the cleaning requirement of the high-precision guide rail is difficult to meet.
2. Mechanical cleaning although mechanical cleaning improves cleaning efficiency to some extent, the prior art such as the full-automatic cleaning and drying equipment for the precise linear guide rail disclosed in publication No. CN220005155U has some problems in the cleaning process. In the linear guide rail conveying process, cleaning liquid sprayed by the spray cleaning machine can be attached to the surface of the guide rail, so that friction force between the linear guide rail and the conveying roller is reduced, and the guide rail is made to slip in the conveying process. This not only affects the cleaning efficiency of the linear guide but also increases the relative movement between the guide rail and the conveying roller due to the slipping phenomenon, thereby increasing the risk of the surface of the guide rail being scratched, thereby affecting the accuracy of the linear guide.
