Embodiment 1

[0026] Such as figure 1 As shown, a coating device for a curved cover plate 1 includes:

[0027] The sputtering mechanism 2 is used to spray the coating material in a predetermined direction at a sputtering rate corresponding to the coating area in the predetermined direction;

[0028] The moving mechanism 3 is used to drive the curved cover plate 1 to move, and sequentially move different coating areas on the curved cover plate 1 to predetermined directions.

[0029] The coating device divides the entire curved surface on the curved cover plate 1 that needs to be coated into a plurality of coating areas, and one coating area corresponds to a sputtering rate for coating, so that the curved cover plate 1 is coated. The relative angles and relative distances between each coating area and the target shower head of the sputtering mechanism 2 are different, and the coating material can be aligned with the coating area in a predetermined direction by controlling the sputtering mech...

Embodiment 2

[0041] Such as image 3 As shown, a method for coating a curved cover plate is applied to the coating device for a curved cover plate described in Embodiment 1, including the following steps:

[0042] Step 1: the moving mechanism sequentially moves different coating areas on the curved cover plate to predetermined directions;

[0043] Step 2: the sputtering mechanism ejects the coating material sequentially at a sputtering rate corresponding to the coating area in a predetermined direction.

[0044] Before step 1, step 0 is also included: preset different coating areas on the curved cover plate and their corresponding sputtering rates.

Embodiment 3

[0046] A readable storage medium stores a computer program that can be executed by a processor. When the computer program is executed by the processor, the method for coating a curved cover plate described in the second embodiment is performed.

Abstract

The invention discloses a film coating device and method of a cambered cover plate and a readable storage medium. The film coating device comprises a sputtering mechanism and a movable mechanism. Thesputtering mechanism is used for spraying a film coating material in a preset direction at the sputtering rate corresponding to a film coating area in the preset direction. The movable mechanism is used for driving the cambered cover plate to move, and different film coating areas on the cambered cover plate are moved to the preset direction in sequence. According to the film coating device, the problem that film coating of a cambered cover plate is not even can be solved, and the picture quality of a cambered display screen is improved.

Description

technical field [0001] The invention relates to coating technology, in particular to a coating device for a curved cover plate, a coating method and a readable storage medium. Background technique [0002] The car display screen is one of the important components in the car display device, usually a liquid crystal display, the liquid crystal display is relatively small in size and easy to install, and can be installed near the instrument panel, on the roof, behind the seat back, or even installed on the sunshade on board for easy use in a variety of situations. In addition, vehicle-mounted display devices often integrate other functions, such as simple power amplifier, TV receiving function, audio output, etc., with more types and functions than TV or computer monitors. Therefore, the installation of vehicle-mounted display devices on vehicles is becoming more and more It is welcomed by the public, and the quality of the display screen of the vehicle-mounted display device ...
