In addition, attached drawing is only the schematic illustrations of the disclosure, it is not necessarily drawn to scale.Identical attached drawing mark in figure
Note indicates same or similar part, thus will omit repetition thereof.Some block diagrams shown in the drawings are function
Energy entity, not necessarily must be corresponding with physically or logically independent entity.
The clamping bending mechanism that the curved surface cover board attaching process process of OLED display panel generally first passes through equipment is realized aobvious
The false fitting for showing panel 800 and curved surface cover board 900, is then squeezed and deformed by the rising that lower end flexible curved surface is bonded cushion block 100
The full fitting for realizing display panel 800 and curved surface cover board 900, is shown in showing for the curved surface cover board attaching process of Fig. 2 OLED display panel
It is intended to.
Fig. 3 is that the flexible curved surface of an embodiment of the utility model is bonded the diagrammatic cross-section of cushion block, the utility model
Flexible curved surface is bonded the six face blocks that cushion block 100 is elastomeric cushion material.Above-mentioned elastomeric cushion material can be silica gel, silica gel
Not only compression resistant, high temperature resistant, wear-resistant but also non-toxic and tasteless, does not damage human body, the padded coaming of the utility model is not only
It is limited to silica gel.
It includes a first surface contacted with curved surface cover board that flexible curved surface, which is bonded cushion block 100,；Described the first of the cushion block
Surface is divided into two second contacts of the first contact area 111 and both sides of the edge in first direction (x-axis direction in Fig. 3)
Region 112, second contact area 112 are curved surface.
In the embodiments of the present invention, first contact area 111 can be curved surface, or plane.It is practical
In use, when the first contact area 111 is curved surface, radius of curvature be also it is bigger, curved surface is close and plane.
The first contact area 111 in Fig. 3 is plane, and the second contact area 112 is curved surface.Is defined in the utility model
The region that one contact area 111 is contacted with the second contact area 112 of curved surface is bending region, when this cushion block is applied to curved surface
When cover board attaching process, the bending region that the first contact area 111 is contacted with the second contact area 112 cannot meet fitting to pressure
Power distribution requirement, i.e., in attaching process when the first contact area 111 meets laminate pressure is the smallest to be required when, be bent region
Pressure is excessive, causes the second contact area 112 to crack bad so as to cause product functionality.
In the embodiments of the present invention, flexible curved surface fitting cushion block 100 further include in said first direction respectively with
Two first sides 120 that two second contact areas 112 contact；It is respectively arranged in each first side 120
It is parallel at least groove 121 extended on (the y-axis direction in Fig. 3) in a second direction of the first surface.
In the embodiments of the present invention, the groove 121 being arranged in each first side 120 is in third party
The section on face formed to (the z-axis direction in Fig. 3) and the first direction is two straight lines, straight line and camber line or two arcs
The angle that line is formed, is shown in that Fig. 3-5, the third direction are vertical with the first surface respectively.The angle can be at 20 ° extremely
Between 150 °.
The opening for the groove 121 being arranged in two first sides 120 may be disposed at the lower section of first surface,
It is identical as at a distance from the first surface.
In the embodiment of Fig. 3, section of the groove 121 on the face of third direction and first direction composition is two
When the angle that straight line is formed, it is defined as the first angle theta, sees Fig. 3, it is preferable that θ≤30 °.
The groove 121 is set in each first side 120, role is so that the flexible curved surface is bonded
When cushion block 100 and display panel 800 contact, flexible curved surface is bonded the bending region and 800 contact position of display panel of cushion block 100
Curvature can change due to the stretching on third direction of groove 121, i.e., when cushion block and display panel 800 contact, the second contact
Region 112 can be bent downwardly, thus reduce the pressure that display panel is bonded at bending region, so that the first contact area 111,
The laminate pressure for being bent region and the second contact area 112 is uniform, thus reduce that display panel bending region cracks and
Cause display panel functionality bad.
The curvature in bending region and 800 contact position of display panel due to the utility model can be since groove 121 be along the
The upward flexible and a certain range of change of tripartite, therefore, in the embodiments of the present invention, second contact area
112 curvature of curved surface can be identical as the curvature of the curved surface cover inner surface, and there may also be a certain range of differences.
Similarly, as shown in figure 4, section of the groove 121 on the face of third direction and first direction composition
For two camber lines formed angle when, be defined as the second angle α, α≤30 °.
An example according to the present utility model, the groove 121 is on the face of third direction and first direction composition
Section when being the angle that straight line and arc are formed, be defined as third angle β, 90 °≤β≤150 °
In the another embodiment of the utility model, it is respectively arranged in each first side 120 multiple in third
The section on face that direction is formed with the first direction is that two straight lines, straight line and camber line or two camber lines form the recessed of angle
Slot 121, multiple grooves 121 are arranged along the third direction, and the angle of each groove can be different, can also be identical.
Similarly, the utility model flexible curved surface fitting cushion block can further include two be oppositely arranged and respectively with institute
State first surface contact second side, each second side equally can be set it is fluted, be used for uniform attaching process
The laminate pressure in the bending region of the curved surface on middle second direction (direction y).
The utility model additionally provides a kind of flexible curved surface laminating apparatus, is bonded cushion block including above-mentioned flexible curved surface,
The flexible curved surface laminating apparatus is for realizing the full fitting of display panel and glass cover-plate in curved surface cover board attaching process.
In conclusion the utility model provides a kind of flexible curved surface fitting cushion block, for six faces for elastomeric cushion material
Block；The cushion block includes a first surface contacted with curved surface cover board；The first surface of the cushion block is along first direction
On be divided into two the second contact areas of the first contact area and both sides of the edge, second contact area is curved surface；The pad
Block further includes two first sides contacted respectively with two second contact areas in said first direction；It is each described
It is respectively set in first side and is parallel at least groove that the second party of the first surface upwardly extends.
The curvature in the bending region of the flexible curved surface fitting cushion block of the utility model passes through groove stretching on third direction
It contracts and realizes change in a certain range, therefore, there is no need to the deformation using OLED display panel absorptive table padded coaming,
It is not required to solve since the material, hardness, deformation effect of padded coaming are bad or the hair of bubble caused by the service life of padded coaming
Product quality problem caused by raw rate is higher.Relative to fixed cushion block identical with bend glass cover board curvature, the utility model
Flexible curved surface fitting cushion block design have groove, it is a degree of variable to realize cushion block bending region curvature, and it is aobvious to improve OLED
It is excessive to show that panel is bonded bending areal pressure in the process with curved surface cover board, to be bent region during reducing fitting with other areas
The pressure distribution difference in domain.Pressure distribution during fitting more evenly can reduce the crackle of product edge, improve the property of product
Can, such as bending region can generate scarce color phenomenon after reduction fitting.
