Problems solved by technology

Multi-station dismantling will only set up a negative pressure working environment at the station where the backlight module is disassembled. If the backlight module is damaged at other stations, the mercury vapor will directly leak into the air after the lamp tube is broken. Harm to operators, low safety, and pollution to the environment; in addition, the production line is suitable for large-scale dismantling tasks, while dismantling small batches leads to waste of resources and poor flexibility
[0004] Based on the above, there is an urgent need for a liquid crystal display dismantling device to solve the problems that the existing liquid crystal display dismantling methods cannot guarantee the complete absorption of mercury vapor, have poor flexibility, low safety, and are not energy-saving and environmentally friendly.

Abstract

The invention discloses a disassembling device for a liquid crystal display screen, relating to the technical field of production of display devices. The disassembling device of the liquid crystal display screen is of a box-type workbench; the box-type workbench comprises a workbench board, an air return system for forming a negative pressure environment and a filtering device which are arranged inside; the air return system comprises at least one air inlet hood and a centrifugal fan; the air inlet hood is arranged above the workbench board; an air inlet of the centrifugal fan is communicated with the air inlet hood through the filtering device and an air inlet pipe; an air outlet of the centrifugal fan is communicated with the outside through an air outlet pipe. The disassembling device for the liquid crystal display screen can create an independent negative pressure working environment for disassembling the liquid crystal display screen and ensure that mercury vapor can be completely absorbed, and is high in flexibility, high in safety, energy-saving and environment-friendly.

Description

technical field [0001] The invention relates to the technical field of display device production, in particular to a dismantling device for a liquid crystal display. Background technique [0002] With the rapid development of the liquid crystal display industry and the continuous upgrading of display technology, the amount of liquid crystal display waste is increasing year by year. Since the discarded liquid crystal displays contain various recyclable materials and rare and precious metal indium, in recent years, the recycling and reuse of various materials in the discarded liquid crystal displays has attracted great attention from many research institutions at home and abroad. [0003] At present, there are mainly two methods for dismantling LCD screens by manufacturers recycling LCD screens on the market: one is to disassemble on a separate dismantling table. That is, dismantling is carried out on a separate LCD dismantling table, but not in an independent negative pressu...
