Automatic film feeder and film coating method thereof

This creation belongs to the technical field of surface film processing, especially regarding an automatic film feeder and its film coating method, which can greatly improve the film speed and quality, and can save the film material and avoid waste.

According to various 3C products such as smart phones, tablets and notebook computers, the demand for these 3C products is increasing day by day, especially for portable 3C products such as smart phones and tablets. Features such as wireless network and mobile network enable modern people to get the latest information anytime, anywhere. For modern people, these 3C products are already part of life.

In order to pursue visual beauty, it is usually added with some patterns or colors on the outer casing, or materials such as leather or silicone to create a visual beauty different from traditional 3C products. Since most of the outer casings are made of plastic or aluminum-magnesium alloy, the three-dimensional pattern is directly formed on the surface of the outer casing by injection molding, and the decorative effect is added by baking paint or painting. However, the 3C product using metal as the outer casing is limited by the existing metal surface decoration treatment technologies, such as chemical coloring, electrolytic coloring, decorative plating or metal surface etching, although the surface decoration effect can also be achieved. The effect of the decoration is monotonous and the processing cost is high, which is prohibitive. The above-mentioned pattern or color decoration is still a flat expression, and in order to prevent falling off or fading, it is necessary to pass through a protective film or a protective cover. Protection to ensure durability and inconvenience.

Therefore, this creator has applied for the Republic of China invention patent No. I385078 "Purple "External light-cured stereo image transfer method", new patent No. M430384 "UV transfer machine", new patent No. M441567 "automatic film transfer machine" and new patent No. M444537 "film transfer device", etc. It is a method of using film transfer and photocuring material to directly produce a three-dimensional decorative treatment with protective effect on the surface of the outer casing.
