Description

Technical Field

[0001] This utility model belongs to the field of transmission manufacturing technology, and relates to parts cleaning, specifically to a mobile sampling device for the cleanliness of automotive parts. Background Technology

[0002] Cleanliness refers to the degree of contamination of specific parts, assemblies, and complete machines by impurities. It represents the amount of dirt remaining on the surface of a part or product after cleaning, characterized by characteristic parameters such as the mass, size, and quantity of impurity particles collected from specific locations using prescribed methods. In recent years, the automotive manufacturing industry has imposed increasingly stringent requirements on the cleanliness of parts, making product cleanliness a key factor in determining product reliability. Therefore, improving product cleanliness helps enhance market competitiveness and meet increasingly higher customer expectations.

[0003] Cleanliness testing requires sample extraction, also known as impurity collection. Impurities are removed from the sample through a high-pressure rinsing process. Then, all the cleaning medium and separated impurity particles are filtered through a filter membrane, and the membrane is analyzed to obtain the cleanliness test results. The sampling process is the most crucial step in the entire cleanliness testing process; the appropriateness and effectiveness of sample collection directly affect the accuracy of the test results.

[0004] The conventional cleanliness sampling process involves sending the parts to be sampled to a cleanliness testing station, where they are cleaned and samples are collected using a professional cleanliness sampling box. This method has the following main problems: (1) low sampling efficiency, taking about 2 hours; (2) the sampling process involves parts transfer, which may cause secondary contamination of the samples; (3) the parts must be protected after sampling to prevent rusting or damage; (4) this method is suitable for small-batch, discontinuous parts production, but it is difficult to ensure the integrity of product batches and smooth production rhythm for large-batch assembly line production and production modes with high batch management requirements.
