Description

Technical Field

[0001] The invention relates to the technical field of display screen production, in particular to a curing device for producing a liquid crystal display screen. Background Art

[0002] The production and processing of LCD screens requires multiple work steps. Among them, the glue dispensing and curing in LCD screen production refers to the process of using a glue dispenser to apply specific glue to the LCD screen during the production of the LCD screen, then covering the back panel with the glue, and curing the screen through the cooperation of the curing movable seat and the pressure head to fix and seal the screen and the back panel.

[0003] At present, when some display screen curing equipment is in use, the staff can first place the display screen that has been glued and covered with the back panel on the curing movable seat in the curing equipment, and then limit the display screen by the pressure head to assist the curing of the display screen. In the process of the curing movable seat driving the display screen to move, the back panel is prone to displacement because the glue has not solidified. When the staff collects and transfers the display screen with the covered back panel, the back panel is still prone to displacement during the transfer of the unfinished product because the glue has not solidified, which affects the subsequent curing effect of the display screen. In addition, manual covering by the staff is likely to affect the accuracy of the back panel placement position. Summary of the invention

At this time, the ventilation hood 1513 adsorbs the back plate and moves it to the top of the storage box 16, and the electric push rod 121 starts to drive the polarizer and the pressure plate 28 to descend, and the micro air pump 14 is turned off. At this time, under the action of the elastic force of the first compression spring 19, the slide plate 17 is reset, and the pressure plate 28 cooperates with the force plate to drive the bending rod 27 to descend, and the inclined plate 26 is forced to rotate and drive the support plate 241 to move, so that the display screen can be placed inside the storage box 16, and the polarizer can stably cover the top of the display screen. Finally, the staff starts the electric push rod. The rod 121 works in the reverse direction, the pressure plate 28 cooperates with the force-bearing plate, and under the cooperation of the elastic force of the second compression spring 243, the support plate 241 and the bending rod 27 are reset, the motor 101 starts and works in the reverse direction, and the support mechanism 24 can be moved again to the bottom of the dispenser body 5 to prepare for supporting the subsequent display screen, the cross plate 13 moves to the top of the positioning platform 30, and the adsorption component 151 adsorbs the back plate. At the same time, the airbag 1523 cooperates with the slide plate 17 to limit the display screen and the back plate at the same time, the second guide rail 6 cooperates with the moving seat body 7 to move the display screen to the bottom of the pressure head body 3, and the pressure head body 3 is started to press and limit the display screen to prepare for the subsequent curing of the display screen. After the adsorption component 151 adsorbs the back plate on the top of the positioning platform 30,The connection mechanism 29 cooperates with the lower wedge block 41 to drive the auxiliary mechanism 40 to move, thereby loading the back plate, and repeating the above operation to complete the dispensing and curing operation of the display screen.
