A new type of continuous evaporation coating production line

Abstract

The invention discloses a novel continuous evaporation coating production line. The novel continuous evaporation coating production line sequentially comprises movable rotation support plates (1), a vertical gate valve I (2), a substrate inlet vacuum cavity (3), a vertical gate valve II (4), a coating vacuum cavity (5), a vertical gate valve III (6), a substrate outlet vacuum cavity (7) and a vertical gate valve IV (8). Sequential and continuous entering and exiting of the movable rotation support plates (1) is achieved through manual circulation or production line circulation to achieve coating production. The novel continuous evaporation coating production line has the advantages that processes such as heating preprocessing and vacuum plasma cleaning are achieved by optimizing the coating vacuum cavity, the processes can be optionally combined according to product process needs, and various product production processes are facilitated; due to the fact that the substrate inlet vacuumcavity and the substrate outlet vacuum cavity are isolated from the coating vacuum cavity, the substrate inlet cavity and the substrate outlet cavity can be independently optimized, full-automatic coating production is achieved, worker participation is reduced, and product yield is increased.

Description

technical field [0001] The invention relates to the technical field of evaporation coating production lines, in particular to a novel continuous evaporation coating production line. Background technique [0002] Decorative coatings, photoelectric functional films and optical coatings are widely used in daily consumer fields, such as home appliances, mobile phones, smart homes and automotive displays, especially electron beam evaporation coatings have promoted the wide application of decorative coatings, photoelectric functional films and optical color films in these fields. field used. Among them, the promotion of major domestic manufacturers such as Shenzhen Vindali, Bourne Optics, Truly Semiconductor, Lens Technology and OFILM Optical in the field of mobile phones has further promoted the rapid development of these industries. At present, the coating industry of decorative coating, photoelectric functional film and optical coating generally has the problem of using monome...

AI Technical Summary

Problems solved by technology

[0003] 1. First of all, the production capacity of the monomer coating machine is limited. Taking simple color film coating as an example, the loading and unloading time of the monomer coating machine is 15-20 minutes, and the coating time is 15-30 minutes. The time for the whole batch of goods is 30-50 minutes, the daily production capacity can only reach 6-10 furnaces, which is very limited;

[0004] 2. Secondly, the coating process of the monomer evaporation coating machine is very independent. Due to the different manufacturing process and debugging methods of the commissioning personnel, the coating process of each equipment is different; therefore, products with the same performance can be completed , the operation method and production process of each equipment are very different, which also causes the control of coating and the increase of production cost;

[0005] 3. Moreover, since the production of each furnace of the monomer evaporation coating machine needs to be independently entered and exited from the coating vacuum chamber, the coating vacuum chamber is exposed to the atmosphere and dust environment, resulting in very high environmental requirements for the coating workshop. High; especially for relatively high-end decorative coatings and optical coatings, it needs to be carried out in a class 100 dust-free environment at the loading and unloading positions

[0006] 4. In addition, the pretreatment of the substrate in vacuum is very important, but it takes a very valuable takt time to complete it on a single coating machine, which cannot form the advantage of mass production

The manual loading mode of the monomer coating machine cannot avoid the re-contamination of the substrate by human operation, and the uncontrollable quality caused by human operation differences;
