Automotive Cleanliness Analysis SystemIt is a device used to detect the degree of particulate matter pollution in automotive parts and other components. It can analyze characteristic parameters such as the quality, size, and shape of particulate matter, providing data support for cleanliness control in the automotive production process.

Working Principle:

Detection based on optical principles: First, the components to be tested are cleaned with a specialized cleaning device and suitable cleaning solution to remove impurities. Then, the cleaning solution containing impurities is filtered through a specific aperture filter, and the impurities are trapped in the filter. Next, place the dried filter screen into a cleanliness detector, and use a high-resolution camera and optical lens to scan the entire surface of the filter screen. Using the different light absorption or scattering rates of the object surface and pollutant particles, capture impurity images, and then use image analysis algorithms to automatically identify the type, size, and quantity of impurities.

Detection based on scanning electron microscopy and energy dispersive spectrometer: With scanning electron microscopy and energy dispersive spectrometer as the hardware foundation, particles on the filter membrane can be scanned. The electron gun emits an electron beam to impact the particles, generating signals such as secondary electrons and backscattered electrons. These signals are collected by the detector to form an image of the particles. The energy dispersive spectrometer detector can analyze the chemical composition of the particles, thereby achieving rapid identification, analysis, classification and statistics of the particles.

　　Automotive Cleanliness Analysis SystemMain technical parameters:

Particle detection range: It can generally detect particles of 5 μ m and above, and the detection limit may vary among different devices.

Measurement accuracy: It is related to electrode constant, scanning accuracy, etc., for example, the scanning accuracy can reach 1.0 μ m.

Analysis speed: Depending on the performance and automation level of the equipment, some devices can complete the scanning and analysis of the filter membrane in a relatively short time.
