Airbag laminating device and method for curved glass on touch screen

Abstract

The invention discloses an airbag laminating device and method for curved glass on a touch screen. The airbag laminating device comprises a support plate and a fixture platform located below the support plate, wherein the fixture platform is used for positioning the curved glass; a main airbag is arranged on one side of the support plate close to the fixture platform; an auxiliary airbag is arranged at a position inside the main airbag corresponding to a bent part of the curved glass; the auxiliary airbag is used for tightly laminating a flexible film to the bent part of the curved glass. The airbag laminating device improves a stress structure of the bent part of the curved glass during lamination by arranging the auxiliary airbag corresponding to the bent part of the curved glass in the main airbag, and increases pressure of the bent part during lamination, so that the flexible film is further laminated to the bent part of the curved glass under compression effect of the auxiliary airbag, thereby eliminating the lamination bubbles of the flexible film and the curved glass, increasing the lamination quality and reducing yield loss.

Description

technical field [0001] The invention relates to the technical field of touch screen production, in particular to an airbag bonding device and a bonding method for curved glass on a touch screen. Background technique [0002] In recent years, with the development of modern science and technology and the advancement of information technology, flexible organic light-emitting diode technology has developed rapidly, and various manufacturers have gradually launched curved surface electronic products such as curved mobile phones and curved TVs. During the production, curved glass and flexible organic light-emitting diodes are required to be bonded. Due to the difficulty of curved surface technology, the mainstream vacuum air bag bonding method is prone to bonding bubbles, especially at the R angle position due to insufficient pressure. Yield loss. [0003] Therefore, when laminating curved glass and flexible organic light-emitting diodes, it is necessary to use airbags to improve...

Problems solved by technology

The working state of the airbag bonding device is as follows: figure 2 As shown, the fixture table 2 for positioning the curved glass 6 is located directly below the flexible film 5; the bonding process is as follows image 3 As shown, the main airbag 3 is inflated, and the flexible film 5 is bonded to the curved glass 5 under the pressure of the main airbag 3 until the bonding is completed, but the bending part of the curved glass 6 under the device is less stressed, The curved portion of the main airbag 3 and the curved glass 6 cannot be completely overlapped. After bonding, air bubbles 10 are likely to appear in the curved portion of the flexible film 5 and the curved glass 6, resulting in poor bonding, such as Figure 4 shown
