Embodiment Construction

[0023] The present invention will be further described below in conjunction with the accompanying drawings.

[0024] Depend on figure 1 It can be seen that a liquid crystal panel recycling process includes the following steps:

[0025] (1) Put the LCD panel to be processed on the conveyor belt, cut the LCD panel into a suitable size with a laser cutting machine, and let the LCD panel with the same size after cutting be transported on the recycling line;

[0026] (2) After cutting, the glass on both sides of the LCD panel is separated from the middle, so that the liquid crystal in the middle of the glass on both sides is enriched and separated by ultrasonic water washing, and the cleaning water is connected to the ultrasonic water tank through the circulation pipe for recycling, and then the hot air circulation drying device is used Blow out hot air at 60-80 degrees Celsius to dry the LCD screen, creating a good drying condition for further scraping the surface of ITO, that is...

Abstract

The invention discloses a liquid crystal display panel recycling process which includes the steps: placing a liquid crystal display panel on a conveying belt; cutting the liquid crystal display panel into a proper size by a laser cutting machine; separating glass on two sides of the liquid crystal display panel from the middle after cutting to clean and enrich liquid crystals between the glass on the two sides; drying a liquid crystal display by hot air; sucking the glass of the liquid crystal display panel from the upper portion by a vacuum sucker; scraping an ITO (indium tin oxide) surface layer of the lower portion on an assembly line by a grinder to obtain ITO and powder of parts of the glass; collecting indium-rich powder and the glass powder without the ITO obtained by separation through a dust removal system; crushing the glass of the liquid crystal display panel without the ITO layer into powder, and crushing plastics in the liquid crystal display panel into flakes; finally, separating the glass powder from the flaky plastics by screening. The liquid crystal display panel recycling process has the advantages of high efficiency, no pollution, high resource recovery rate, simplicity in operation and the like, and is suitable for large-scale industrial application of environmental protection and resource recovery enterprises.

Description

technical field [0001] The invention relates to a liquid crystal panel recycling process, which belongs to the electronic waste treatment technology. Background technique [0002] The development of electronic information technology in the 21st century is changing with each passing day, and the human-computer interaction equipment of electronic products is also constantly improving. Display is an important part of electronic products. As the main window for electronic products to output information to users, it has always been the focus of research. In recent years, it has developed from a large-volume, high-radiation, high-power consumption cathode tube display to an energy-saving, low-radiation, ultra-thin LCD display, and even a touchable LCD display. At present, LCD monitors, LCD TVs, notebook computers, tablet computers and mobile phones are the main application fields of LCD screens. According to statistics, in 2011, the total sales of liquid crystal displays in my c...
