Substrate dust-removal device for processing diffusion diaphragm

Abstract

The invention discloses a substrate dust-removal device for processing a diffusion diaphragm. The substrate dust-removal device comprises an unwinding frame, a material reel, a substrate, a guiding roller, an electrostatic eliminator, traction rollers, a traction motor, a suction hood, an air filter, an exhaust pipe, a centrifugal fan, an injection frame, a spraying head fixing frame, a branch airpipe, a total air pipe and high-frequency solenoid valves. Through unwinding of the unwinding frame and cooperation of the guiding roller and the traction rollers, the substrate moves horizontally onthe top face of the dust-removal device at the constant speed, passes through the electrostatic eliminator firstly from right to left for electrostatic eliminating, and then enters the upper part ofthe suction hood, a controller controls the high-frequency solenoid valves to sequentially be closed and opened, thus high-frequency pulse airflow is formed to impact the surface of the substrate, dust is disengaged from the surface of the substrate, dust-containing gas is sucked by the suction hood, filtered by the air filter and then is discharged to the indoor space, in the whole process, the traction rollers and the guiding roller do not make contact with the surface of the substrate, abrasion of dust particles on the surface of the substrate is reduced, and the substrate is protected.

Description

technical field [0001] The invention relates to the technical field of optical film production, in particular to a base material dust removal device for diffusion film processing. Background technique [0002] The optical film printing production method is used in the backlight module of the display screen. It is a precision part. The substrate needs to be processed before processing. The function of the coating machine is to coat the rolled substrate plastic film with a layer of glue and paint with specific functions. Or ink and other coatings, and the base material is dried and rolled. However, in the actual coating process, the surface of the coated substrate is often inevitably adhered to fine dust, suspended particles and other sticky dust. If the dust adhering to the surface of the substrate is not cleaned before coating Sticky dust will lead to uneven coating and affect the performance of the product. During the coating process, the dust adhering to the substrate no...
