The first platform 100 is used for bearing the display panel 1 to be laminated, wherein the display panel 1 to be laminated comprises a first surface and a second surface which deviate from each other, the second surface is arranged on the first platform 100, the first surface is opposite to the first platform 100 and is used for subsequent film lamination, alignment correction is needed to be carried out on the display panel 1 to be laminated after the display panel 1 to be laminated is placed in order to ensure lamination accuracy, specifically, symmetrical marks 11 are arranged on the first surface and the second surface of the display panel 1 to be laminated, at least one pattern acquisition component 200 is arranged above and below the first platform 100, the pattern acquisition component 200 is used for acquiring actual images of the marks 11 on the display panel 1 to be laminated, and in the embodiment, the pattern acquisition component 200 is a video camera. Since the second surface is disposed on the first platform 100, the pattern capturing assembly 200 cannot directly capture and capture the actual image of the mark 11 on the second surface, and thus a plurality of through holes 101 are formed in the first platform 100, and the through holes 101 are used to expose the mark 11 on the second surface, so that the pattern capturing assembly 200 captures and captures the actual image.
In another preferred embodiment of the present invention, at least one pre-alignment mark 12 is provided at the 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 acquisition component 200 captures and acquires the image of the pre-alignment mark 12, that is, indicates that the pre-alignment of the display panel 1 to be attached is completed, so that the phenomenon that the mark 11 is not in the identification frame of the pattern acquisition component 200 due to the overlarge position error of the display panel 1 to be attached in the subsequent identification process of the mark 11 is avoided, and the phenomenon that the mark 11 cannot be identified is generated. In this embodiment, the marks 11 are disposed on the first surface and the second surface of the display panel 1 to be attached at intervals, so that the problem that the marks 11 exceed the recognition frame of the pattern acquisition assembly 200 is further reduced.
In particular, the bonding apparatus in this embodiment can bond display panels 1 with different sizes, and marks 11 with different shapes are provided on the display panels 1 with different sizes to be bonded, as shown in fig. 2, three display panels 1 (a first display panel 1a to be bonded, a second display panel 1b to be bonded, and a third display panel 1c to be bonded) with different sizes to be bonded are provided in this embodiment, where the first mark 11a of the first display panel 1a to be bonded, the second mark 11b of the second display panel 1b to be bonded, and the third mark 11c of the third display panel 1c to be bonded are corresponding to each other. In this embodiment, the first mark 11a is rectangular, the second mark 11b is cross-shaped, and the third mark 11c is circular, and in other preferred embodiments of the present invention, any number of display panels with different specifications and sizes and any shape of marks may be included, and only the marks 11 with different shapes corresponding to the display panels 1 to be attached with different specifications and sizes need to be satisfied.
