Abstract

The invention provides a bonding device for bonding films on a bound device. The bonding device comprises a bonding roller, and glue plates for filling low-fluidity glue; the bonding roller comprisesa winding drum, and absorbing plates wound on the outer peripheral surface of the winding drum in sequence; the absorbing plates comprise first surfaces and second surfaces oppositely arranged; the first surfaces are provided with negative-pressure holes for absorbing the films; the glue plates are laminated on the second surfaces of the absorbing plates; and when the winding drum rotates, along with gradual bonding of the films on the bonded device, the glue plates and the absorbing plates are gradually unfolded and laminated on the films in sequence. The invention further provides a film bonding method; and the film bonding method comprises the following steps: the bonding roller is downwards pressed to rotate from the edge of the bonded device; the films, the absorbing plates and the glue plates are gradually unfolded from the winding drum to bond on the bonded device in sequence; and at the same time, the low-fluidity glue is injected in or extracted out from the glue plates untilthe bonding is finished. The film bonding method reduces such problems as product warpage after bonding.

Description

technical field [0001] The invention relates to the field of bonding of membranes, in particular to a bonding device and a bonding method. Background technique [0002] With the advancement of display technology, flexible display screens have gradually become the mainstream, and the requirements for lamination of films such as polarizers are getting higher and higher, and lamination technology is becoming more and more important. [0003] At present, polarizers are generally bonded by rollers, and the bonding method is as follows: figure 1 As shown, the display panel 1' is vacuum-adsorbed on the first platform 2', the polarizer 3' is vacuum-adsorbed on the second platform 4', the roller 5' is pressed on the front ends of the display panel and the polarizer, and the first platform 2' It moves relative to the second platform 4' to complete the lamination. However, due to the excessive pressure of the roller at the edge, it will cause such as figure 2 Defects such as warpin...
