Description

Technical Field

[0001] The present invention relates to the technical field of dust-free cloth detection, and in particular to a device for detecting dust content in a dust-free cloth. Background Art

[0002] Dust-free cloth is a high-performance cleaning tool, widely used in environments that require high cleanliness, such as semiconductors, electronics, optics, medical and aerospace. The dust content of dust-free cloth is generally measured by a particle counter to measure the number of particles on the surface of the dust-free cloth or in the air after wiping to evaluate its cleanliness. Particle size detection can be divided into two methods: dry and wet. Dry detection directly measures the number of particles in the air after wiping, while wet detection is performed in a liquid environment.

[0003] Chinese patent (CN108279203A) discloses a large particle detection device for dust-free cloth, including a detection device body, a fan and a particle counter. The present invention is used to detect the content of particles attached to the dust-free cloth after production. During use, the dust-free cloth to be detected is placed into the drum from the dust-free cloth inlet and outlet, the drum drive motor drives the drum to rotate, and the fan drive motor drives the fan to blow the air filtered by the air filter through the electrostatic precipitator from the top of the drum to the drum. The large particles on the dust-free cloth are blown by the wind and enter the conical particle inlet on the particle counter through the conical collector. The particle counter detects the content of large particles in the dust-free cloth.

[0004] However, there are some drawbacks in the above-mentioned related technologies. For example, during use, some existing dust-free cloth dust content detection devices generally directly put the dust-free cloth into the drum and rotate it, and use an external fan to remove dust, resulting in insufficient dust removal efficiency and poor dust removal effect.
