All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present application. Furthermore, it should be understood that the detailed description and specific examples, while indicating exemplary embodiments of the invention, are given by way of illustration and explanation only, and are not intended to limit the scope of the invention. In the present application, unless indicated to the contrary, the use of the directional terms "upper" and "lower" generally refer to the upper and lower positions of the device in actual use or operation, and more particularly to the orientation of the figures of the drawings; while "inner" and "outer" are with respect to the outline of the device.
The embodiment of the application provides a laminating device of a display panel and an application method thereof. The details will be described below.
Examples
As shown in fig. 1, in the embodiment, the attaching device of the present invention is used for attaching a display panel 1 to be attached, and specifically, the attaching device includes a first platform 100, a pattern obtaining assembly 200, a processor 300, a moving assembly 400, and a second platform 500.
The first platform 100 is used for bearing the display panel 1 to be attached, wherein the display panel 1 to be attached includes a first surface and a second surface which are deviated from each other, the second surface is arranged on the first platform 100, the first surface faces away from the first platform 100 and is used for subsequent film layer attachment, in order to ensure the accuracy of attachment, after the display panel 1 to be attached is placed, the display panel 1 to be attached needs to be aligned and aligned, specifically, symmetrical marks 11 are arranged on the first surface and the second surface of the display panel 1 to be attached, at least one pattern acquisition assembly 200 is arranged above and below the first platform 100, and the pattern acquisition assembly 200 is used for acquiring an actual image of the mark 11 on the display panel 1 to be attached, in this embodiment, the pattern acquisition assembly 200 is a camera. Since the second surface is disposed on the first platform 100, the pattern capturing assembly 200 cannot directly capture an actual image of the mark 11 on the second surface, and therefore, the first platform 100 is provided with a plurality of through holes 101, and the through holes 101 are used for exposing the mark 11 on the second surface, so that the pattern capturing assembly 200 can capture the actual image.
In another preferred embodiment of the present invention, at least one pre-alignment mark 12 is disposed at an edge of the display panel 1 to be attached, and when the display panel 1 to be attached is placed on the first platform 100, the at least one pattern obtaining assembly 200 captures and obtains an image of the pre-alignment mark 12, that is, the pre-alignment of the display panel 1 to be attached is completed, so as to avoid that the mark 11 is not in the identification frame of the pattern obtaining assembly 200 due to an excessive position error of the display panel 1 to be attached during the subsequent identification of the mark 11, and the phenomenon that the mark 11 cannot be identified occurs. In this embodiment, the marks 11 are disposed at intervals on the first surface and the second surface of the display panel 1 to be attached, so as to further reduce the problem that the marks 11 exceed the identification frame of the pattern acquisition assembly 200.
In particular, the attaching device in this embodiment can attach the display panels 1 to be attached of different specifications and sizes, and the display panels 1 to be attached of different specifications and sizes are provided with the marks 11 of different shapes, as shown in fig. 2, in this embodiment, three display panels 1 to be attached of different specifications and sizes (a first display panel 1a to be attached, a second display panel 1b to be attached, and a third display panel 1c to be attached) are provided, wherein the first mark 11a corresponding to the first display panel 1a to be attached, the second mark 11b corresponding to the second display panel 1b to be attached, and the third mark 11c corresponding to the third display panel 1c to be attached are provided. In this embodiment, the first mark 11a is rectangular, the second mark 11b is cross-shaped, and the third mark 11c is circular, but in other preferred embodiments of the present invention, any number of display panels with different specifications and sizes and any shape of mark may be included, and it is only necessary to satisfy the different specifications and sizes of the mark 11 corresponding to different shapes of the display panel 1 to be attached.
In other preferred embodiments of the present invention, the marks 11 on the display panels 1 to be attached with different specifications and sizes have the same shape, but have different marks, such as the arabic numerals 1, 2, and 3 … marked in the circular patterns, so as to achieve the technical effect of distinguishing the display panels 1 to be attached with different specifications and sizes.
After acquiring the actual image of the mark 11, the pattern acquiring assembly 200 transmits the actual image to the processor 300, in this embodiment, the processor 300 retrieves a preset image with the same shape in the library according to the shape of the actual image, where the coordinate of the preset image is the standard position of the display panel 1 to be attached corresponding to the actual image, that is, the coordinate difference between the actual image and the preset image corresponds to the offset between the display panel 1 to be attached and the reference position, the processor 300 transmits the coordinate difference to the moving assembly 400, and the moving assembly 400 moves the first platform 100 or directly moves the display panel 1 to be attached, so as to compensate the offset, and thus the display panel 1 to be attached is moved to the standard position.
In this embodiment, since the preset images corresponding to the actual images of different shapes are different, the standard positions of the display panel 1 to be attached with different specifications and sizes are stored in the processor 300, so that when the display panel 1 to be attached is replaced, the position of the pattern acquisition component 200 does not need to be adjusted manually, the offset between the pattern acquisition component and the standard position does not need to be recalculated according to the specification and size of the display panel 1 to be attached, and the large-scale, industrial and automatic production is facilitated.
The second platform 500 and the first platform 100 are arranged in an up-and-down alignment manner, and when the display panel 1 to be attached is displaced to the standard position, the second platform 500 and the first platform 100 are close to each other and extruded, so that the film layer on the second platform 500 is attached to the display panel 1 to be attached, and the attachment is completed.

S4), the pattern capturing component 200 transmits the actual image to the processor 300, and the processor 300 retrieves the corresponding preset image according to the shape of the actual image, in other preferred embodiments of the present invention, the processor 300 may also retrieve the preset image corresponding to the label of the actual image according to the label of the actual image, and calculate the coordinate difference between the actual image and the preset image.
In particular, in this embodiment, the preset images include a first preset image, a second preset image and a third preset image, the first preset image corresponds to the first display panel to be attached, the second preset image corresponds to the second display panel to be attached, and the third preset image corresponds to the third display panel to be attached. The projection area of the first display panel to be attached on the first platform is smaller than the projection area of the second display panel to be attached on the first platform; the projection area of the second display panel to be attached on the first platform is smaller than the projection area of the third display panel to be attached on the first platform.
S5) the processor 300 transmits the coordinate difference value to the moving assembly 400, which moves the first platform 100 or the display panel 1 to be attached according to the coordinate difference value.
S6) the second platform 500 and the first platform 100 are close to each other and pressed, so that the film layer on the second platform 500 is attached to the display panel 1 to be attached, and the attachment is completed.
