Problems solved by technology

[0004] Now for large-sized curved screens such as curved screens for TVs, rolling is often used to bond the curved protective cover and flexible film, but for small-sized mobile phone curved screens, the distance between the edges of the curved screen is small, and it is flexible during the rolling process. The film is easy to contact with the curved edge of the curved surface protection cover first, causing relative friction between the flexible film and the curved edge, resulting in defective products

Embodiment 1

[0035] Such as figure 1 as shown, figure 1 It is a structural schematic diagram of the rolling device of the mobile phone screen of the present invention; the rolling device of the mobile phone screen of the present invention includes an upper component and a lower component, the lower component is provided with a flow roller table, and the curved surface protection cover 1 is fixedly arranged on On the flow roller table, the upper assembly is provided with a flexible film 2 and a carrier tape 3; the flexible film 2 is attached to the lower end surface of the carrier tape 3, and the shape of the carrier tape 3 can be changed through the upper assembly In this way, the flexible membrane 2 has an arc shape, the central part of the flexible membrane 2 is at the lowest position and is first attached to the curved surface protection cover 1, and the flexible membrane 2 is gradually moved by the upper assembly. Rolling onto the curved surface protection cover 1 , so as to achieve l...

Embodiment 2

[0045] Preferably, the gripper device 6 includes a gripper base 61, a gripper cylinder and a gripper group 62, and the gripper base 61 is movably connected to two gripper rails; the gripper cylinder and the gripper The clamping groups 62 are all arranged on the clamping base 61, the clamping cylinders are fixedly connected to the clamping groups 62, and the clamping cylinders control the clamping action of the clamping groups 62, that is, through The clamping cylinder can realize the clamping operation of the clamping device 6 on both ends of the carrier tape 3 .

[0046] The gripper base 61 is set in a plate shape with a certain width, and the fitting roller 51 is arranged between the two gripper groups 62, and the gripper base 61 can be moved away from or Close to the fitting roller 51 . One side of the gripper base 61 is provided with a gripper motor 63, the gripper motor 63 is fixed on the mounting plate 4, and the output shaft of the gripper motor 63 corresponds to the g...

Embodiment 3

[0052] Such as Figure 5 as shown, Figure 5 It is a schematic flow chart of the bonding method of the mobile phone screen of the present invention; the bonding method of the mobile phone screen of the present invention comprises the steps of:

[0053] S1, attaching the flexible film 2 to the carrier tape 3, and moving the curved protective cover 1 to directly below the carrier tape 3 through the flow roller table;

[0054] S2, fixing the end of the carrier tape 3 attached with the flexible film 2 by the clamping device 6;

[0055] S3, by moving the position of the clamping group 62 and pressing down the fitting roller 51, the carrier tape 3 forms an arc surface, and the central part of the carrier tape 3 and the curved surface protection cover The central part of 1 is in contact with the fit;

[0056] S4, adjust the limit roller 71, and release the clamping effect of the clamping group 62 on the end of the carrier tape 3, so that the end of the carrier tape 3 overlaps the ...

Abstract

The invention discloses a mobile phone screen rolling pressing device and an attaching method. The mobile phone screen rolling pressing device comprises an upper part assembly and a lower part assembly, wherein the lower part assembly is provided with a flowing roller way; a curve surface protection cover plate is fixedly arranged on the flowing roller way; the upper part assembly is provided witha flexible film and a carrying belt; the flexible film is attached onto the lower end surface of the carrying belt; through the upper part assembly, the shape of the carrying belt can be changed to enable the flexible film to form an arc-shaped surface, so that the center part of the flexible film is the lowest and is attached to the curve surface protection cover plate first; through the upper part assembly, the flexible film is gradually roll-pressed onto the curve surface protection cover plate so as to realize the attaching of the curve surface protection cover plate and the flexible film. The flexible film attaching is performed by aiming at the curve surface protection cover plate with the right-angular or acute angle edges; the adverse defects of bubble drapes and the like of the flexible film in the attaching process can be avoided; under the effect of a position limiting device, the first contact of the end part of the flexible film and the curve surface edge position of thecurve surface protection cover plate is avoided; the defective products are reduced.

Description

technical field [0001] The invention relates to the technical field of mobile phone screen production, in particular to a rolling device and a bonding method for a mobile phone screen. Background technique [0002] Curved screens generally use non-rigid glass as the substrate, which has better elasticity and is not easy to break, so it has the advantage of low screen wear rate; at the same time, the curved screen setting of the screen can make the screen thinner, lighter in weight, lower in power consumption and increase the reliability. viewing angle. [0003] When used in mobile phones, the overall curved design of the curved screen is conducive to gripping, and fits better with the curvature of the palm of the hand, reducing the distance between the thumb touching the screen during one-handed operation, and theoretically helping to increase the horizontal span of the large-size screen. The experience of screen operation; the seemingly subtle curve can allow mobile phone ...
