S2 passes through fixed 4 end of the carrier band for being pasted with the flexible membrane 3 of the clamp hand device 6；
S3 is pushed up the carrier band 4 until by the carrier band 4 and the pressure by rising the pressing block 51 for the first time
It closes block 51 to be close to, and the carrier band 4 is in tensioning state；
S4, by rising the pressing block 51, and the decline by adjusting the clamp hand device 6 and horizontal shifting for the second time
It is dynamic, so that the end of the carrier band 4 and the flexible membrane 3 is bonded the edge of the pressing block 51, causes the carrier band 4 and described
Flexible membrane 3 is in bending；
S5 limits 4 end positions of the carrier band by the pressing device 7, and the clamp hand device 6 is released to the carrier band
The clamp position of 4 ends；
S6, the upper cavity and lower chamber contraposition closure form closed space, and take out to the closed space
Vacuum is to setting vacuum values；
S7 makes 51 middle section of pressing block contact the curved surface at first by rising the pressing block 51 for the third time
Cover sheet 2, and in the continuous uphill process for stating pressing block 51, the flexible membrane 3 is gradually fitted in the curved surface and is protected
Until the flexible membrane 3 and the curved surface cover sheet 2 are completely bonded on cover board 2；
S8 declines the force fit plate, and releases limitation of institute's clamping device to 4 ends of the carrier band, the flexible membrane 3,
The carrier band 4 and the curved surface cover sheet 2 pass through the upper cavity and the lower chamber on the placement platform 1
Separation removes the carrier band 4, to be finally completed the display device to release vacuum state from the flexible membrane 3
Fitting.
In specific steps S2, the both ends of the carrier band 4 are individually positioned in the upper folder portion 65 and lower folder portion of the clamping group
Between 64, and the placement to guarantee the carrier band 4, by driving second cylinder 63 to make the upper folder portion 65 and institute when beginning
It states and is separated by a distance between lower folder portion 64.It is placed in the lower folder portion 64 of two sides when the both ends of the carrier band 4 are fallen
When, second cylinder 63, which drives, to be caused the decline of upper folder portion 65 and and then realizes clamping effect to the both ends of the carrier band 4.
Then by driving first cylinder 62 so that the clamping group is dropped to setting position.
For the flexible membrane 3 attached on the carrier band 4, the width dimensions of the carrier band 4 are greater than the flexible membrane 3
Width dimensions, the length dimension of the carrier band 4 corresponds in the length dimension of the flexible membrane 3, i.e., the length of the described carrier band 4
Size is equal or slightly larger than the length dimension of the flexible membrane 3.
The flexible membrane 3 is located at the center of the carrier band 4, and the long side two sides of the carrier band 4 can exceed after completing to attach
The long side two sides of the flexible membrane 3, consequently facilitating limitation is fixed by the clamp hand device 6 and the pressing device 7.
In step S3, specifically when the carrier band 4 is gripped by the clamping group, the lifter plate 52 rises；Institute
State some moment of the contact surface of pressing block 51 in uphill process contacts with the bottom surface of the carrier band 4, and later with institute
State the bottom surface that the carrier band 4 is raised under the constantly raised drive of lifter plate 52.
Risen by the lifter plate 52 and the rising of pressing block 51 and the clamping group clamping effect is driven to cause institute
Carrier band 4 is stated in tensioning state, to prevent the flexible membrane 3 from generating fold when fitting to the curved surface cover sheet 2；Simultaneously
The tensioning state of the carrier band 4 can guarantee the close contact of the carrier band 4 and 51 contact surface of pressing block.
Preferably, placing the institute of the curved surface cover sheet 2 during the carrier band 4 is stretched to tight state
Setting position can be dropped under the driving of the lifting device 8 by stating placement platform 1, and the setting of 4 parts of the carrier band can be made to exist
In the curved surface cover sheet 2, but the flexible membrane 3 is not released with the curved surface cover sheet 2, is protected convenient for the subsequent curved surface
The fitting of protecting cover plate 2 and the flexible membrane 3 reduces the shift motion of the lifter plate 52 during fitting.It is worth noting that
The carrier band 4 is not limited in when being stretched, the placement platform 1 simultaneously declines.
In step S4, when the placement platform 1 drops to setting position, 52 second of the lifter plate drive pressure
The rising for closing block 51, while the pressing block 51 rises, the driving by rising the first cylinder 62 makes the clamping group
Position decline, 4 ends of the carrier band are pulled in the downward side direction of clamping condition of the clamping group；And the drive motor 10 is opened
It is mobile to the direction of the pressing block 51 to open the control pedestal 61.
In the rising of the pressing block 51 and the decline of the clamping group and while progress is moved horizontally, the carrier band 4
End pulled under by the clamping group clamp position to the 51 downside direction of pressing block, to make the carrier band 4 in institute
State the bending of 51 marginal position of pressing block.During being bent 4 end of the carrier band, beyond described in 51 edge of pressing block
3 end sections of flexible membrane because being bent together under the drive of the carrier band 4.The bending part of the flexible membrane 3 and it is described carrier band 4,
The contact surface of the pressing block 51 is close to form the identical shape of curvature.
In the step s 7, rise the pressing block 51 from by third time, protect the pressing block 51 in the curved surface
The center of cover board 2 starts gradually to be bonded to the two sides of curved edge 21；When the third time of the pressing block 51, which rises, to be started, institute
The first interior side contacts with the curved surface cover sheet 2 of centerline portion between 51 contact surface of pressing block, two long side are stated, therefore right
The central part for carrying the flexible membrane 3 on the upside of in the of the 4 preferentially central contact with the curved surface cover sheet 2 should be fitted in
It is bonded.
During the subsequent pressing block 51 continues rising, the curvature of the contact surface is the curved surface protection cap
Plate 2 is constantly pressed down after contacting, so that the flexible membrane 3 where making on the contact surface gradually fits to curved surface cover sheet
On 2；Until the fitting of the flexible membrane 3 gradually proceeds to the boundary part of the curved edge 21 of the curved surface cover sheet 2, when
After the third time last time of the pressing block 51 is finally completed, the contact surface keeps it completely solid toward 3 end of flexible membrane pressure
It is fixed on the curved edge 21 of the curved surface cover sheet 2, finally realizing the curved surface cover sheet 2 and the flexible membrane 3
It is bonded and completes display device.
Applying method through the invention can be carried out for the curved surface cover sheet 2 with right angle or edge of acute angle
The flexible membrane 3 is bonded, and is made gradually fitting of the flexible membrane 3 in the curved surface cover sheet 2, is avoided the flexible membrane 3
The bad defects such as bubble fold are generated during fitting；Meanwhile the flexible membrane is avoided under the action of pressing device 7
First releasing at 3 ends and 2 marginal position of curved surface cover sheet, reduces the defective products of production.
The foregoing is merely presently preferred embodiments of the present invention, is merely illustrative for the purpose of the present invention, and not restrictive
's.Those skilled in the art understand that in the spirit and scope defined by the claims in the present invention many changes can be carried out to it,
It modifies or even equivalent, but falls in protection scope of the present invention.
