Embodiment 1

[0038] Such as Figure 2-6 As shown, this embodiment provides a device for bonding curved surfaces of flexible panels, which includes a curved cover fixing platform 100 and a flexible panel adsorption platform 200. Above the adsorption table 200 , the main body 130 of the curved cover plate fixing table is made of metal material, and the curved surface shape of the curved cover plate is that the edge of the curved surface of the cover plate is curved. The curved cover plate fixing platform 100 includes an adsorption hole 110 for fixing the curved surface cover plate 120 and a first working contact surface for fixing the curved surface cover plate 120 , the first working contact surface faces the flexible panel adsorption platform 200 . Preferably, the curved cover plate fixing table 100 further includes a contact pad 101 , and the first working contact surface is the surface of the contact pad 101 facing the flexible panel adsorption table 200 . The shape of the first working...

Embodiment 2

[0043] The flexible panel curved surface laminating device provided in this embodiment is roughly the same as that in Embodiment 1, the difference is that, as Figure 7 As shown, in this embodiment, the flexible panel adsorption table 200 is located above the curved cover plate adsorption table 100. In this way, after the vacuum is released from the adsorption hole 210 in any area, the flexible panel 220 is attached to the corresponding position of the area. When the surface of the cover plate 120 is curved, due to the effect of gravity, the fit between the two will be more compact, further reducing the generation rate of air bubbles.

Embodiment 3

[0045] Such as Figure 2-6 As shown, this embodiment provides a method for bonding curved surfaces. When the flexible panel 220 is to be bonded, the flexible panel 220 and the curved cover 120 are close to each other but not in contact. Preferably, the curved cover 120 is fixed on the curved cover fixing platform 100 through the adsorption channel 110, the flexible panel 220 is adsorbed on the flexible panel adsorption platform 200 through the adsorption channel 210, and after image alignment and correction, the flexible panel The suction table 200 and the curved cover plate fixing table 100 approach each other and reach the position to be bonded, so that the flexible panel 220 and the curved cover plate 120 are close to each other but not in contact. The above preferred mode does not constitute a limitation to the present invention, as long as the flexible panel 220 and the curved surface cover 120 are in a position to be bonded close to but not in contact with each other whe...

Abstract

The invention provides a device and method for laminating curved surfaces of flexible panels. By setting adsorption channels on the flexible panel adsorption table and dividing the second working contact surface of the flexible panel adsorption table into multiple areas, any area can It is independently controlled to release the vacuum in the adsorption holes in this area to stop the adsorption of the flexible panel in this area. When laminating, the adsorption channels in one area are selected to release the vacuum first, and then the adsorption channels in the area adjacent to the area that has been released from the vacuum are released from the vacuum, and the cycle is repeated until the adsorption channels in all areas are released from the vacuum, so that the flexible panels are laminated in turn. On the curved cover, the air is squeezed out of the space between the two, reducing the occurrence of air bubbles. The implementation of the present invention does not need to use the flexible panel to absorb the deformation of the buffer material of the table, so it solves the problem of the material, softness and hardness of the buffer material, the poor deformation effect, or the high incidence of air bubbles caused by the life of the buffer material. product quality problem.

Description

technical field [0001] The invention belongs to the field of display panels, and in particular relates to a device and method for laminating curved surfaces of flexible panels. Background technique [0002] Flexible panels are developed on the basis of OLED (Organic Light Emitting Diode, organic light emitting diode) technology. At present, AMOLED (Active-matrix organic light emitting diode, active matrix organic light emitting diode) technology has become the mainstream cutting-edge technology of flexible panels. After Samsung, more and more panel manufacturers are investing in flexible AMOLED technology. Restricted by technical factors, the main application form of flexible panels in the current market is mobile phone terminals with curved edges of the cover. Such as Samsung S7Edge, Note 7, VIVO X6 play, etc., are all such applications. The lamination technology of 3D cover panels is required in the production of the above products, also known as curved cover panel lamin...
