Description

Technical Field

[0001] The utility model relates to the technical field of mask box processing, in particular to a dustproof film surplus material cutting device. Background Art

[0002] PC sheets are primarily made of polycarbonate resin, a transparent engineering plastic. Polycarbonate resin is a colorless or slightly yellowish transparent granule with excellent light transmittance, impact resistance, heat resistance, aging resistance, and flame retardancy. Through processing, PC sheets can be manufactured in various shapes and sizes to meet diverse application requirements. PC sheets are used as the raw material for photomask pods. During production, a dust-proof film is applied to the surface. Due to the film's slightly larger size, the edges need to be trimmed. Traditionally, manual trimming can easily cause tilting, resulting in uneven cuts. Utility Model Content
