Description

TECHNICAL FIELD

[0001] The utility model relates to online cleaning equipment technical field, concretely is a kind of coating online cleaning device. BACKGROUND

[0002] In the film coating production process, there are tiny dust particles in film material or environment, and the tiny particles are clamped between the coating back roll and the film material, causing slight deformation of the film material, and black point-shaped defects appear in projection inspection after gluing. High requirements are required for optical products, and strong light reflection and transmission inspection, color light source projection inspection will be carried out. The above-mentioned tiny particles are clamped between the coating back roll and the film material, causing slight deformation of the film material, causing the glue layer in the deformation area to be different from other areas, and the refractive index of the glue layer and the film material is different, thereby forming a projection black point phenomenon, but high requirements for optical products are strictly prohibited from such defects.

[0003] The film online dust removal device can reduce the number of tiny particles, but cannot completely remove the tiny particles on the film material. At the same time, the higher the level of dust-free room, the fewer the tiny particles, but it is also impossible to completely eliminate the generation of tiny particles, so it is necessary to install a dust removal device and an online cleaning device on the coating back roll to produce such high-quality optical products.

[0004] The dust removal device on the coating back roll can remove the particles on the back roll in time, but once the particles that cannot be removed by the dust removal device appear, personnel need to enter the coating chamber for wiping operation, which will affect the airflow in the coating chamber and cause vortex. However, maintaining uniform airflow is crucial to the stability of the dust-free room, and the entry and exit of personnel during the coating process will cause the number of point defects of optical products to increase, and in severe cases, dense point defects will occur, causing the product appearance to be unqualified.

[0005] At the same time, if the particles on the coating back roll are not wiped off in time, projection black point defects will occur, and in severe cases, periodic defects will occur. In addition, manual cleaning by personnel also has safety hazards, and manual wiping operation cannot clean the middle position well when coating wide products.

[0006] Therefore, it is urgent to improve the online cleaning method without affecting the stability of the dust-free room, so that personnel do not enter the coating chamber, and the equipment can be automatically cleaned, the production speed is not reduced, the work efficiency is improved, and the personnel safety operation is ensured.
