[0002] In the field of automation and photoelectric measurement, static electricity is generated on the surface of the transported plastic parts due to the friction between the transmission components and the transported plastic parts or other reasons during the transmission of the cylindrical plastic samples / bottles / tubes. The concentration of static electricity charges can easily cause errors in the test results in the precise optical detection instrument, and the static electricity charges can also affect the uniformity of the paint distribution in the coating process, increase the safety risk of electronic devices by adsorbing impurity dust particles in the air, and affect the reliability and service life of the whole machine. In actual design and detection, it is found that the commonly used static electricity removing fan is large in size, which is not conducive to installation, and the generated ions cannot fully contact the surface of the articles that need to remove static electricity, so that the static electricity is not completely removed, resulting in inaccurate measurement results.
