Problems solved by technology

[0003] As a solution to this problem, an adhesive roller is used to remove dust, fibers, and film fragments from the surface of the plastic film, but the effect of removing impurities due to the retransfer of dust from the adhesive roller, etc. is insufficient.
In addition, since the static electricity generated when peeling off the bonding roll

Embodiment Construction

[0040] Embodiments of the present invention will be described in detail below with reference to the accompanying drawings.

[0041] figure 1 It is a schematic side view showing the overall structure when the membrane washing system of the present invention is installed in the membrane coating apparatus.

[0042] Such as figure 1 As shown, the film coating device 40 of the present embodiment is provided with an unwinding part 42 of a plastic film roll, a film washing system 10 of the present invention, a coating part 44, a drying part (drying part after coating) 46, a winding Section 48. The sheet-like plastic film 12 that is sequentially unwound from the unwinding portion 42 of the plastic film roll is conveyed to the film washing system 10 of the present invention by the conveying rollers 14 and 16 .

[0043] figure 1 The membrane washing system 10 has: washing sections 36 and 36 for washing the moving membrane with washing liquid; and a drying section 38 for drying the w...

Abstract

The invention provides a membrane washing system that can continuously remove fine dust, diaphragm or tainting substance that attached to the plastic membrane. The system comprises a washing part (36) that washes a mobile membrane with washing liquid; and a drying part (38) that drys the washed mobile membrane. The washing part (36) is provided such a structure that at least one side of the membrace is supplied with washing liquid while moving the membrane (12).

Description

technical field [0001] The present invention relates to the cleaning system of the film that continuously washes the dust, diaphragm and pollutants attached to the surface of the plastic film, especially relates to the film cleaning of the film used in the FPD (flat panel display) field, electrical field, optical field, etc. that require cleanliness system. Background technique. [0002] Plastic films have been widely used in various fields such as the FPD field, the electrical field, and the optical field. Plastic films used in the FDP field and the electrical field are used as components and process materials through processes such as film formation, coating, and lamination. This manufacturing process must be operated in a clean environment from beginning to end, and defects such as contamination and adhesion of impurities such as dust, fibers, and film fragments to the product, and the occurrence of physical defects such as scratches and indentations caused by these defe...
