Embodiment Construction

[0013] The present invention will be further described below in conjunction with the examples, but not as a limitation of the present invention.

[0014] See figure 1 , the inclined optical plastic substrate coating device of the present embodiment includes a coating umbrella placed in a vacuum furnace, an evaporation source and a conductive rod, the coating umbrella is provided with side plates and umbrella surfaces, and the substrate to be coated is placed on the side plates. The included angle between the side plate and the horizontal is 70-85°, and the evaporation source is arranged at the lower part of the coating umbrella. The conductive rod is an oxygen-free copper rod with a diameter of 10 cm and a length of 1.0 m. The conductive rod is divided into left and right two and fixedly arranged between the plastic substrate and the evaporation source. The angle between the conductive rod and the surface of the plastic substrate is 0-5°, and the distance between the conduct...

Abstract

The invention discloses an optical plastic substrate coating device, which comprises a coating umbrella placed in a vacuum furnace, an evaporation source and a conductive rod. The coating umbrella is provided with a side plate and an umbrella surface, and the side plate and the umbrella surface are used for When placing the substrate to be coated, the evaporation source is arranged in the coating umbrella, the conductive rod is arranged between the substrate and the evaporation source, the angle between the conductive rod and the surface of the substrate is 0-5°, and the conductive rod and The distance between the substrates is 20-40 cm, and the conductive rods are connected to a 1.2-1.5 kV power supply. The coating device enables the plastic substrate coating to obtain good firmness without using the IAD process.

Description

technical field [0001] The invention relates to a film coating device, in particular to a film coating device for evaporating an optical plastic substrate. Background technique [0002] Optical plastics refer to plastics used as optical media materials. It is mainly used in optical instruments to manufacture optical substrates, lenses, contact lenses, organic optical fibers, etc. The optical plastics that have been applied mainly include PMMA, PET, PC, PS and so on. In the future, plastic substrates can replace glass substrates as next-generation display materials, because plastic substrates have the advantages of being lighter, thinner, impact-resistant, and rollable than glass substrates, and can be applied to many portable and wearable display devices to increase their service life. And increase the scope of use. At present, plastic substrate coating is used as a transparent material with excellent performance in the optoelectronic industry and can be applied to touch ...
