Problems solved by technology

The current appearance design of curved screens tends to be borderless, which poses a huge challenge to 3D bonding, the core technology of curved screens. In 3D bonding technology, the cover glass and display screen need to be bonded, and the bonding The quality of the screen is largely affected by the cleaning technology and cleaning equipment before lamination. The quality of the cleaning technology and cleaning equipment determines the high efficiency and high quality of laminating the flexible display panel on the protective cover glass; With the emergence of ring screens, both sides of the display module have a certain bending angle, and the cleaning requirements for the cover glass are also getting higher and higher. As the bending angle becomes larger and larger, it is easy to cause the cover glass to be curved. Partial cleaning is not in place, and the coating on the cover glass is damaged and other high-rate defective problems

Embodiment Construction

[0054] Terms used in the embodiments of the present application are only for the purpose of describing specific embodiments, and are not intended to limit the present application. The singular forms "a", "said" and "the" used in the embodiments of this application and the appended claims are also intended to include plural forms unless the context clearly indicates otherwise.

[0055] An embodiment of the present application provides a cleaning device, such as figure 1 As shown, it is used to clean the cover 2. The cover 2 is generally a glass cover. With the emergence of curved screens, in order to ensure a good bonding effect between the cover 2 and the display panel, there will be corresponding The position is curved to fit better with the display panel, so as to achieve a better effect of curved screen or ring screen.

[0056] In this kind of structural fit, since the cover plate 2 has a curved arc position, before the cover plate 2 is bonded to the display panel, it is n...

Abstract

The invention relates to the technical field of electronic products and particularly relates to a cleaning nozzle, cleaning equipment and a cleaning method of a cover plate. The cleaning nozzle comprises through holes, wherein airflow sprayed out of the through holes is used for cleaning the surface of the cover plate; the cleaning nozzle comprises a rotating shaft, so that the cleaning nozzle can rotate along the rotating shaft; the cleaning nozzle at least further comprises a first surface and a second surface; the through holes comprise first through holes and second through holes; a plurality of first through holes are formed in the first surface; a plurality of second through holes are formed in the second surface; the cover plate comprises a plane area and arc-shaped areas; when the cleaning nozzle rotates, the airflow sprayed out of the first through holes can be sprayed to the plane area; and the airflow sprayed out of the second through holes can be sprayed to the arc-shaped areas. Through adoption of the cleaning nozzle, the cleaning equipment and the cleaning method of the cover plate, the cleaning effect on the cover plate is improved so as to adapt to cleaning of the cover plates with different bending angles; and meanwhile, the damage to coating films on the cover plates is avoided.

Description

technical field [0001] The present application relates to the technical field of electronic products, in particular to a cleaning method for cleaning nozzles, cleaning equipment and cover plates. Background technique [0002] With the emergence of flexible screens, the application of flexible screens will experience explosive growth in the future, and the 3D (three dimensional) form of flexible screens will also undergo subversive changes in the near future. At the same time, curved screens will gradually Become the core competitive technology point of various mobile phone manufacturers. The current appearance design of curved screens tends to be borderless, which poses a huge challenge to 3D bonding, the core technology of curved screens. In 3D bonding technology, the cover glass and display screen need to be bonded, and the bonding The quality of the screen is largely affected by the cleaning technology and cleaning equipment before lamination. The quality of the cleaning...
