Description

Technical Field

[0001] The invention relates to the field of screen production devices, and in particular to a screen pressure maintaining device. Background Art

[0002] With the development of society, more and more electrical equipment will be installed with screens, so that users and electrical equipment can achieve better human-computer interaction. The current screen usually includes a panel and a display screen. The panel can protect the display screen. The bonding methods of the panel and the display screen include full bonding and non-full bonding. Full bonding is to use water glue or optical glue to completely stick the panel and the display screen together in a seamless manner. Patent application number: CN202222567735.5 discloses a positioning and pressure-maintaining device for screen attachment, including a first positioning component for fixing the panel frame and a second positioning component for positioning the screen. The second positioning component includes a bottom lifting drive member and a shifting table installed on the driving end of the bottom lifting drive member. A positioning member that can be lifted and lowered through the panel frame and is used to position the screen is installed on the top of the shifting table. A pressing component that can be lifted and lowered to press the screen to the panel frame is arranged above the first positioning component. The panel frame is fixed on the first positioning piece, and the screen to be bonded is installed on the positioning piece. The shift table can be moved forward, backward, left and right to adjust the position of the screen accordingly, so that the screen can be aligned with the panel frame. The bottom lifting drive member descends, so that the screen is initially positioned in the panel frame, and then the pressing assembly presses the screen into the panel frame to complete the screen positioning and pressure holding operation. However, this type of transfer can only perform pressure holding operation on one screen at a time, resulting in low screen production efficiency.
