How to efficiently control the cleanliness inspection of parts?
Source：
Author：
With the rapid development of the automotive market and the development of parts cleaning technology, the cleanliness detection and manipulation of automotive parts is becoming more and more critical.
In the manufacturing process of power batteries, air pollution sources in the natural environment of the warehouse workshop adhere to the surface of the parts or enter the internal structure of the parts, which will lead to environmental pollution of the parts. Contaminants are usually fragments of metal materials, metal dust, soot, chemical fibers, oil stains, etc. Untimely and controlled cleanliness detection will directly damage the characteristics and service life of the powertrain From the feedback of the site, especially the automotive market, the direct main manifestation is the initial damage of the automobile engine, the oil circuit plate of the brake system begins to be ineffective, the aging of the automobile steering system, and the initial rust of the vehicle surface.
Comprehensive after-sales service common faults are partially ineffective, according to the production process, the key links of powertrain cleanliness detection and operation are divided into 9 levels:
System factors: vehicle frame clutch control transmission system and automobile steering system refrigeration system and engine, powertrain and braking system, such as gearbox (plastic hose, steel pipe), fuel tank, filter and other supply systems, automotive electrical system, automotive oil category.
Powertrain cleanliness control method:
According to the influencing factors of cleanliness testing and the manufacturing steps of the powertrain, the key to cleanliness control is to remove pollutants, protect against pollutants, self-safety protection of parts, lean management, vehicle recleaning, cleanliness control in the field of hydraulic oil tracking and testing:
1. Removal, that is, to eliminate dust, oil and other pollutants in the natural working environment should be improved according to the implementation of the site 5S, and in strict accordance with the cycle time for combing, rectification, cleaning, in the cleaning work, the operation area and production workshop should maintain stable natural ventilation countermeasures, the dust formed in the production process should be immediately removed, industrial plants emit waste gas and other particles, in order to remove pollutants Electric forklifts are used at all stages of automobile manufacturing, and the use of fuel forklifts is strictly prohibited in the operation area and assembly process workshop to reduce exhaust emissions.
2. The protection of parts and pollutants that need to be protected should be packaged in accordance with the application specifications, tooling fixtures, protective measures should be taken to protect parts and pollutants, such as the application of standard packaging, promote suppliers and built-in fixtures, reduce the whole process of bulk and non-landing storage of parts caused by bag flipping, key appearance parts and spare parts adopt protective clothing.
3. The safety protection of parts refers to the application of various countermeasures to prevent pollutants from entering the parts. The focus is on the self-safety protection of components, the safety of fixtures and the safety of time.
