Abstract

The invention discloses a device and a method for coating a curved cover plate. The curved cover plate is applied to a smart terminal. The device comprises a coating chamber which is connected with at least one coating instrument, a rotation axis which is arranged in the coating chamber and rotates around a first center shaft, and at least one rotation clamp which is connected to the rotation axis and comprises at least one clamp table for placing a curved cover plate, wherein the rotation clamp rotates around a second center shaft; revolving of the rotation axis is used for driving the rotation clamp to rotate; and the axial direction of the first center shaft is the same as that of the second center shaft. According to the device, the rotation axis rotates around the first center shaft in the coating process, and further the rotation clamp is driven to revolve around the first center shaft, and the aim of improving the coating uniformity by controlling the curved cover plate to revolve around the first center shaft and rotate around the second center shaft in the coating process can be achieved.

Description

technical field [0001] The invention relates to the technical field of coating film on a curved cover plate, and more specifically, relates to a film coating device and a film coating method for a curved cover plate. Background technique [0002] With the continuous improvement of people's living standards, people's requirements for smart terminals are also getting higher and higher. In order to meet the user's requirements for a better visual and tactile experience, the researchers developed a curved cover. In addition to the complex molding process of curved cover plates compared with flat cover plates, it is also more difficult to coat curved cover plates. There has always been a problem of poor surface uniformity in the coating of curved cover plates. Contents of the invention [0003] In view of this, the present invention provides a coating device and a coating method for a curved cover plate. During the coating process, the curved cover plate is controlled to revol...
