Embodiment 1

[0035] like figure 1 and figure 2 as shown, figure 1 It is a three-dimensional view of the unlaminated state of the lamination device of the mobile phone screen according to the present invention; figure 2 It is a three-dimensional view of the bonding state of the laminating device of the mobile phone screen according to the present invention; figure 1 and figure 2 The fit and non-fit in are the fit and non-fit of the flexible film and the curved protective cover.

[0036] The laminating device of the mobile phone screen of the present invention includes an upper cavity and a lower cavity, the upper cavity and the lower cavity are arranged in cooperation, and the upper cavity and the lower cavity can move up and down; 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 protective cover 2, and the lower The cavity is provided with a...

Embodiment 2

[0044] like image 3 , Figure 4 , Figure 5 as shown, image 3 It is a partial cross-sectional view of an unbonded state of the lamination device of the mobile phone screen of the present invention; Figure 4 It is a partial structural diagram of the bonding state of the laminating device of the mobile phone screen according to the present invention; Figure 5 It is a partial cross-sectional view of the laminating state of the mobile phone screen lamination device of the present invention. The placement platform 1 is used to support the curved surface protection cover 2, and the placement platform 1 is generally rectangular and has a certain thickness; the placement platform 1 is connected with the lifting device 8 inside the closed space, through the The lifting device 8 can move the placing platform 1 down toward the lifting and pressing part 5 . The pressing block 51 is arranged on the upper part of the lifting and pressing part 5 ; the height of the pressing block 51...

Embodiment 3

[0062] 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.

[0063] 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 lamination device for a mobile phone screen and a pasting method. The lamination device comprises a holding platform, a curved surface protection cover plate, a flexible film, a carrying belt and a lifting pressurizing part, wherein the holding platform is used for holding the curved surface protection cover plate; the flexible film is placed on the carrying belt; the carrying belt is of an elastic and soft tabulate structure; the carrying belt is placed on the lifting pressurizing part; the flexible film and the curved surface protection cover plate are correspondingly arranged up and down; a pair of clamping claw devices are further arranged on a lower cavity; the clamping claw devices are arranged on both sides of the lifting pressurizing part; a limiting device is arranged on an upper cavity; and the limiting device is used for limiting positions of both ends of the carrying belt. By adopting the lamination device, the flexible film is pasted to the curvedsurface protection cover plate with an included angle bent edge, and bubbles, wrinkles and other defects can be prevented in the pasting process of the flexible film; under the action of the limitingdevice, prior contact between an end part of the flexible film with a curved surface edge position of the curved surface protection cover plate is avoided, and defective products can be reduced.

Description

technical field [0001] The invention relates to the technical field of mobile phone screen production, in particular to a lamination device and a bonding method for mobile phone screens. Background technique [0002] The liquid crystal display technology industry has entered a mature stage. Flexible OLED (Organic Light-Emitting Diode, organic light-emitting diode) display is a new growth point for the future display industry. The flexible characteristics of flexible OLED displays are constantly being developed and utilized. Attached to a curved glass cover for front and side display of the product. [0003] For the existing production equipment of liquid crystal display screens on mobile phones, when the flexible film and the curved surface protection cover are laminated, it is generally a flat pressing operation, which is prone to defects such as bubbles and wrinkles, thereby affecting the production of curved display screens. [0004] In view of the above defects, the inv...
