Title:
OIL REMOVAL METHOD, BONDING METHOD, ASSEMBLY DEVICE, AND ATMOSPHERIC-PRESSURE PLASMA DEVICE
Document Type and Number:
WIPO Patent Application WO/2020/026399
Kind Code:
A1
Abstract:
The purpose of the present invention is to provide a technology that enables removal of oil regardless of the shape of an object to which the oil is adhered. By radiating a plasma gas containing oxygen plasma, cutting oil is decomposed. Oxygen radicals decompose carbon components and hydrogen components constituting the oil into carbon dioxide and water, respectively, so as to be removed. Hence, by radiating a plasma gas containing oxygen plasma, it is possible to decompose paraffin and ester contained in the cutting oil. Because the plasma gas can flow along the shape of the object, it is possible to remove the oil regardless of the shape of a portion of the object to which the oil is adhered.
