Specifically, as shown in Figures 2 and 3, roller pressing is carried out far from the side of flexible display screen to laminating layer 3, passed through
Rolling, the surface uniform stressed of laminating layer 3 make to form the OCA optical cement of laminating layer 3 that deformation occurs, laminating layer 3 and cover board are discharged
Air between 2 realizes that cover board 2 is bonded with the closed of laminating layer 3.Wherein, the thickness of laminating layer 3 is the 3% of 2 thickness of cover board,
The air for being conducive to the distortion in rolling of laminating layer 3 to be discharged between laminating layer 3 and cover board 2 promotes between laminating layer 3 and cover board 2
Closed fitting.Meanwhile in the rolling process, broken cover board 2 can be flattened, keeps the integrity degree and planarization of cover board 2,
It is adsorbed on 2 globality of cover board on laminating layer 3, avoids 2 fragment of cover board from scratching screen body or damage to operator, either
Because the warpage of cover board 2, crackle etc. influence the normal fractionation of cover board 2 and flexible display screen.
S30: separation cover board 2 and display module 1；
Specifically, absorptive element adsorbs laminating layer 3, applies the power far from flexible display screen to laminating layer 3, laminating layer 3 with
Cover board 2 is removed together as a whole, to separate cover board 2 and flexible display screen.For example, utilizing existing vacuum suction member
Part to laminating layer 3 carry out vacuum suction, Mobile vacuum absorptive element, on laminating layer 3 apply far from display module 1 power,
Realize that cover board 2 is separated with the disassembly of display module 1.
It should be noted that in the prior art when directly carrying out vacuum suction to broken cover board 2, since fragment can not
It is effectively adsorbed, influences the normal fractionation of broken cover board 2 and display module 1, and be easy to cause display mould since fragment exists
The screen body of group 1 is scratched.And in the present embodiment, the OCA optical cement for forming laminating layer 3 after hardening, has certain hardness,
Broken 2 globality of cover board is adsorbed on laminating layer 3, by carrying out vacuum suction to laminating layer 3, can effectively be filled display
The entirety of broken cover board 2 in setting is removed, and is had high removal efficiency, and be able to maintain that the flatness of broken cover board 2, is prevented it
Further it is crushed.
Above-mentioned method for dismounting makes by the way that laminating layer 3 is arranged on broken cover board 2, and by rolling discharge air
Laminating layer 3 with cover board 2 is closed is bonded, broken cover board 2 can globality be adsorbed on laminating layer 3, be conducive to the lid that will be crushed
The disassembly of 2 monolith of plate, improves the removal efficiency of display device.Meanwhile it can be improved the smooth of broken cover board 2 in the rolling process
Degree prevents cover board 2 from further rupturing, and avoids the fragment of cover board 2 from scratching display module 1, or damage to operator, and
And it can be improved the tidiness of operating environment.And production can be avoided to separate cover board 2 and display module 1 by absorption laminating layer 3
The case where raw absorption of cover board 2 does not live, guarantee cover board 2 is efficiently separated with display module 1.
