Problems solved by technology

[0003] For the existing production equipment of curved display screens, it is generally designed for curved display screens with an obtuse angle structure greater than 90 degrees. For the lamination between the protective covers, the flexible film is easy to contact with the curved edge of the curved protective cover, and it is easy to cause relative contact movement between the flexible film and the curved protective cover during the lamination process, resulting in defective products

Embodiment 1

[0039] like Figure 1 to Figure 8 as shown, Figure 1 to Figure 8 The fit and non-fit in are the fit and non-fit between the curved surface protection cover and the flexible film. The screen processing device of the present invention includes an upper cavity and a lower cavity, the upper cavity and the lower cavity are arranged in cooperation, and both the upper cavity and the lower cavity can move up and down; when the When the upper cavity and the lower cavity are closed, a closed space is formed in the upper cavity and the lower cavity; the upper cavity is provided with a placement platform 1 and a curved surface protection cover 2, and the lower cavity is provided with There are a flexible film 3, a carrier tape 4, and a lifting and pressing part 5; the placement platform 1 is used to place the curved surface protection cover 2, the flexible film 3 is placed on the carrier tape 4, and the carrier tape 4 Placed on the lifting and pressing part 5, the flexible film 3 and t...

Embodiment 2

[0047] like Figure 1 to Figure 4 As shown, the placement platform 1 is used to support the curved surface protection cover 2, the placement platform 1 is generally rectangular and has a certain thickness; the placement platform 1 is connected to the lifting device 8 inside the closed space , the placing platform 1 can be moved down toward the lifting and pressing part 5 through the lifting device 8 . The pressing block 51 is arranged on the upper part of the lifting and pressing part 5 ; the height of the pressing block 51 can be adjusted through the lifting and pressing part 5 .

[0048] The lower end surface of the placement platform 1 is provided with an installation groove for accommodating the curved surface protection cover 2, so that the support curved surface protection cover 2 can be fixed; The vacuum holes on the surface of the curved protection cover 2 are used for absorbing and supporting the curved protection cover 2 .

[0049] The clamping device is arranged o...

Embodiment 3

[0065] The limiting device 7 includes a fixed plate 71, a limiting plate 72 and a third cylinder 73 arranged on the placing platform 1, the fixing plate 71 is fixed on the placing platform 1, and the limiting plate 72 It is fixedly arranged at the end of the telescopic rod of the third air cylinder 73, and the third air cylinder 73 is fixedly arranged on the fixed plate 71, and the limit plate 72 and the mounting plate 72 can be adjusted through the third air cylinder 73. The relative position of the slot.

[0066] The limiting plate 72 is symmetrically arranged on both sides of the installation groove, that is, the limiting plate 72 corresponds to the setting of the curved edge 21 of the curved surface protection cover, and the bottom end of the limiting plate 71 exceeds the placement position. The bottom end surface of the platform 1 ensures the contact between the limiting plate 71 and the carrier tape 4 , so that the carrier tape 4 maintains a certain bending state.

Abstract

The invention discloses a screen processing device and a bonding method. The screen processing device comprises an upper cavity and a lower cavity; the upper cavity and the lower cavity are arranged in a matched mode; the upper cavity and the lower cavity can move up and down; the upper cavity is provided with a placement platform and a hook face protective cover plate; the lower cavity is provided with a flexible film, a carrier band and a lifting pressing portion; the placement platform is used for holding the hook face protective cover plate; the flexible film is arranged on the carrier band; the carrier band is of an elastic and soft flat plate structure; the carrier band is arranged on the lifting and pressing portion; the flexible film and the hook face protective cover plate are arranged correspondingly up and down; through height position adjustment of the placement platform and the lifting and pressing portion, bonding between the flexible film and the hook face protective cover plate is achieved; and by bonding the flexible film to the hook face protective cover plate with a right-angle edge or an acute-angle edge, the end of the flexible film and the hood face edge position of the hook face protective cover plate are prevented from making contact in advance due to the actions of compression deformation of a pressing block and a limiting device, and produced defectiveproducts are reduced.

Description

technical field [0001] The invention relates to the technical field of screen production, in particular to a screen processing device and a bonding method. Background technique [0002] Electronic devices, such as smartphones, mobile phones, and portable media such as tablet computers, have been widely used. In recent years, as people's requirements for electronic devices have increased, electronic devices with curved screens (curved screens) have received more and more attention. favor. Different from flat screens, such curved screens pose challenges to the production of their surfaces due to their own curvature. [0003] For the existing production equipment of curved display screens, it is generally designed for curved display screens with an obtuse angle structure greater than 90 degrees. For the lamination between the protective covers, the flexible film is likely to contact the curved edge of the curved protective cover first, and during the lamination process, it is...
