The current screen usually includes a panel and a display screen. The panel can protect the display screen. The attachment method of the panel and the display screen includes full attachment and non-full attachment. Full attachment is to completely paste the panel and the display screen together in a seamless manner by using water glue or optical glue. Patent application No. CN202222567735.5 discloses a positioning and pressure maintaining device for screen attachment, which includes a first positioning assembly for fixing a panel frame and a second positioning assembly for positioning a screen. The second positioning assembly includes a bottom lifting drive and a displacement table installed on the driving end of the bottom lifting drive. The top of the displacement table is installed with a positioning piece that can be lifted through the panel frame and is used for positioning the screen. A pressing assembly is arranged above the first positioning assembly and can press the screen to the panel frame. The panel frame is fixed on the first positioning piece, and the screen to be attached is installed on the positioning piece. The displacement table can move forward, backward, left and right to adjust the position of the screen correspondingly, so that the screen can be aligned with the panel frame. Then the bottom lifting drive is lowered to preliminarily position the screen in the panel frame. Subsequently, the pressing assembly is pressed down to press the screen into the panel frame, and the screen positioning and pressure maintaining operation is completed. However, such a transfer can only press one screen at a time, resulting in low screen production efficiency.
