Curved glass panel for mobile phone and forming method thereof

Abstract

The invention discloses a mobile phone curved glass panel and a preparation method thereof. The curved glass panel body takes the X-axis or Y-axis center line of the mobile phone panel body as the center and curves to the same side in an arc shape or takes the center line of the mobile phone panel body as an arc. The center point is the center and the periphery is curved in an arc to the same side; or, the curved glass panel of the mobile phone includes a main panel and a curved panel, and the curved panel is formed by bending at least one side of the main panel, and a plurality of the The curved panel is bent to the same side relative to the main panel. The molding method includes three steps: preparation of flat glass panels, manufacture of graphite molds, and molding of curved glass panels. The invention utilizes the good lubricating properties of graphite, and by applying a certain deformation pressure, realizes thermal deformation at a temperature below the softening point of glass, and the product has high dimensional accuracy, meets the design requirements of 3D mobile phone glass panels, and can realize large-scale industrial production and reduce production costs. , to meet people's demand for personalized and fashionable mobile phones.

Description

technical field

[0001] The invention discloses a mobile phone curved glass panel and a forming method thereof, belonging to the technical field of mobile phone panel preparation. Background technique

[0002] Mobile phones with curved glass panels are generally called 3D mobile phones in the industry, and the curved glass panels of mobile phones are called 3D glass panels.

[0003] Traditional mobile phone panels are usually made of flat glass, but this single style cannot meet people's pursuit of fashion and personalization today. Due to the curved shape of the human body, the mobile phone cannot be in close contact with the human body when it is carried around. The human body fits tightly, making the human body very uncomfortable. In addition, the earpiece and microphone of the tablet phone are placed at both ends of the phone. When answering the call, the earpiece end is close to the ear, and the microphone end is close to the mouth. However, because the panel of the mo...
