Disassembly process of a liquid crystal display

Abstract

The invention discloses a disassembling process of a liquid crystal display. The disassembling process specifically comprises the following steps: firstly, disassembling a bracket and a rear cover of the liquid crystal display; secondly, performing ash removal treatment on the liquid crystal display; thirdly, disassembling plastic clamping parts of the liquid crystal display, taking out a protective cover, and disassembling an LVDS (low voltage differential signaling) line in the protective cover; fourthly, splitting non-separated elements of the liquid crystal display; finally, conveying a reflecting plate with a lamp tube into a disassembling machine, and disassembling the mercury-containing lamp tube, wherein in the disassembling process of the lamp tube, dissipated mercury steam needs to be absorbed, and the mercury steam content of discharged gas needs to be detected. When the liquid crystal display is disassembled by using the process, 80 percent of ash gathered in the liquid crystal display can be removed in a centralized manner through the ash removal treatment.

Description

technical field [0001] The invention relates to the field of recycling electronic products, in particular to a dismantling process of 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 screen waste is increasing year by year. Since the waste liquid crystal display contains various recyclable materials and rare and precious metal indium, in recent years, the recovery and reuse of various materials in the waste liquid crystal display has attracted great attention of many research institutions at home and abroad. [0003] Due to the long-term use or long-term storage of discarded liquid crystal displays, there is a lot of dust inside. At present, the manufacturers who recycle liquid crystal displays on the market directly disassemble and recycle their internal components, resulting in a large amount of dust in the recycled compo...

Problems solved by technology

[0004] The lamp tube in the LCD screen contains a large amount of mercury. When the lamp tube is disassembled, it is very easy to damage the lamp tube. Because mercury is poisonous, it will cause great damage to the body if workers inhale it during disassembly, and mercury escapes into the atmosphere. The environment is polluted. However, almost none of the manufacturers currently on the market have carried out detection and treatment procedures for mercury during production.
