Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of camera processing, and particularly relates to a glass tray automatic film covering device and a film covering method thereof. BACKGROUND

[0002] With the development of mobile phone photography technology, in recent years, once a new mobile phone is released, people's attention is increasingly focused on the parameters of the mobile phone camera, such as image sensor, aperture size, focusing method, whether there is optical image stabilization, and how many cameras. Although mobile phone manufacturers are constantly increasing the promotion of photography, the introduction of the material, process, and assembly structure of the mobile phone camera protection glass sheet is very little. Users often complain on the Internet that the camera glass sheet is broken or scratched. In fact, the role of the mobile phone camera protection glass sheet cannot be ignored, because its material, surface treatment, and assembly structure will directly affect the mobile phone camera imaging quality. The camera protection glass sheet not only has a protective effect, but also takes responsibility for the light entering the camera. Normally, manufacturers who have requirements for photography will perform three times of coating on the transparent area of the camera protection glass sheet, once for blue film, and once for red film. The main function of the two film layers is to filter out infrared light and blue light that is not conducive to imaging, and to reduce reflection and increase transparency. The two layers of film are coated on the inner surface of the camera glass sheet, and the camera base color is usually printed before the coating process.

[0003] In the printing process before the coating process, the other side needs to be printed after coating on one side of the protective glass sheet. The existing coating operation is manually tearing, cutting, and coating by the operator, which is slow, and usually only one glass sheet can be coated at a time, with low efficiency and irregular coating affecting the printing quality.
