[0025] With the continuous development of display technology, flexible display panels are increasingly widely used, for example, in display devices such as mobile phones and tablets to achieve three-dimensional display of display devices. Generally speaking, it is necessary to attach the flexible display panel to the curved cover plate so that the display module presents a three-dimensional form. However, the bonding effect between the curved cover plate and the flexible display panel in the related art is poor.

Figure 1 As shown, the laminating device includes a curved platform 1 and a contoured platform 2, and the inner surface of the curved platform 1 and the outer surface of the contoured platform 2 are adapted to the curved cover plate 101. Further, the flexible display panel 102 is placed on the outer surface of the contoured platform 2, and the flexible display panel 102 is stretched and bent to adapt to the curved cover plate 101. However, since the sizes of the curved cover plates are different, it is necessary to replace the curved platform 1 and the contoured platform 2 of different sizes, which is costly.

[0027] The adsorption device for the curved cover plate, the bonding device and the bonding method for the display module provided in the embodiments of the present application fix the curved cover plate by setting a positioning block whose inner wall is an arc-shaped surface. Furthermore, the first positioning block is movably arranged on one side of the first adsorption surface, and the distance between the first positioning block and the second positioning block is adjusted by moving the first positioning block, so that the first positioning block and the second positioning block can adapt to curved cover plates of different sizes, saving costs. Furthermore, the bonding device for the display module can adsorb the flexible display panel through the expansion mechanism, and can also press the flexible display panel by inflation, so as to avoid the generation of bubbles during the bonding process of the curved cover plate and the flexible display panel, thereby improving the bonding effect of the curved cover plate and the flexible display panel.
