DETAILED DESCRIPTION

[0028] In the process of flexible screen, alignment is needed, that is, different material layers, components or groups are accurately aligned to the predetermined position. The alignment is a crucial link in the production process of flexible screen, and the accuracy of alignment directly affects the performance and quality of flexible screen product. At present, the flexible screen is generally accurately aligned by optical alignment, that is, optical detection devices such as optical camera, sensor and the like are installed on the processing equipment to identify the Mark points (reference points) on the flexible screen to realize alignment. These reference points have specific shape, size and contrast, so that the optical system can be easily identified.

The conventional suction fixture is provided with a plurality of vacuum suction holes on the aluminum alloy fixture plate, and the negative pressure generated by the vacuum suction holes is used to realize the suction and fixation of the flexible screen. However, since the flexible screen is directly attached and suctioned on the fixture plate, the flexible screen is easily deformed at the position directly opposite to the vacuum suction hole on the fixture plate due to the large suction force. Meanwhile, when there are dust and other particulate impurities on the fixture plate, the flexible screen is easily damaged and scratched when attached to the fixture plate. Therefore, the yield of the flexible screen product is low.

When adsorbing and fixing flexible screens of different sizes, the first suction cup 310 in the corresponding adsorption area is used to adsorb and fix the flexible screen according to the size of the flexible screen, so as to facilitate the adsorption and fixation of flexible screens of different sizes, and improve the compatibility and application range of the adsorption jig.

The adjustment module 420 is connected to the adsorption module 410, and the adjustment module 420 is used to adjust the horizontal position of the adsorption module 410.

[0048] Please refer to Figure 1 and Figure 2Further, the adjusting module 420 comprises slide rails 421 and a supporting plate 422. The slide rails 421 are arranged in parallel and connected to the side of the adsorption plate 200 perpendicularly.

[0049] Further, in order to improve the compatibility and application range of the FPC adsorption device 400, the supporting plate 422 can be arranged in multiple on the slide rails 421, so that the flexible screen of different sizes can be adsorbed and fixed by adjusting the positions of the supporting plates 422 on the slide rails 421 and the positions of the seats 412 on the supporting plates 422.

[0050] Please refer to Figure 2 Further, in order to accurately position the Mark point on the flexible screen, a boss 210 is arranged on the side of the adsorption plate 200 close to the FPC adsorption device 400. The boss 210 is arranged on the surface of the adsorption plate 200 and flush with the first adsorption disc 310. A second adsorption assembly 600 is arranged on the boss 210 and used for adsorbing and fixing the reference point area of the flexible screen.
