Document Type and Number:
WIPO Patent Application WO/2024/002333
Kind Code:
A1
Abstract:
A collection device, collection method and detection method for magnetic metal particles on the surfaces of a flexible film material. In the collection device (100) for magnetic metal particles on the surfaces of a flexible film material, via the cooperation of an unwinding roller (102), a transmission apparatus, magnetic pieces (104) and a winding roller (103), a flexible film material (200) is transmitted by means of the transmission apparatus, and the flexible film material (200) is respectively wound and unwound by means of the unwinding roller (102) and the winding roller (103). During the transmission process of the flexible film material (200), metal particles on the surfaces of the flexible film material (200) are adsorbed by means of the magnetic pieces (104), so as to collect the magnetic metal particles on the surfaces of the flexible film material (200). In addition, the metal particles on the surfaces of the flexible film material (200) are collected by means of the collection device (100), so that the magnetic metal particles on the surfaces of the flexible film material (200) are effectively removed, thereby improving the surface state of the flexible film material (200), and improving the usage performance of the flexible film material (200).
