Liquid crystal cleaning and production equipment

Abstract

The invention discloses liquid crystal cleaning and production equipment which comprises a plurality of base supports and a conveying belt. The base supports are sequentially arranged on a production line. The top end plane of the first base support is provided with a feeding device, the top end plane of a second base support is provided with a cleaning device, three cleaning liquid circulating systems are installed in the second base support and assembled together with the cleaning device, and the top end plane of the last base support is provided with a water tank. According to the cleaning device, organic matter and cleaning agent residue on the surface layer of liquid crystals are removed through electrochemical oxidation liquid at first, the removal effect on organic matter is enhanced, more importantly, a large amount of waste water containing the cleaning agent can be prevented from being produced, environmental protection requirements can be met, finally pure water is filtered through a self circulation system and then sprayed by a cleaning spray head to the surface layer of the liquid crystals, the liquid crystals are completely and thoroughly cleaned, and no impurity or cleaning agent is left on the surface layer.

Description

technical field [0001] The invention relates to a liquid crystal cleaning production equipment. Background technique [0002] Liquid crystal is a kind of substance with special properties. The liquid crystal material used on the liquid crystal screen is an organic compound with structures such as cholesteryl ester, cyanobiphenyl, and phenylcyclohexane. If it is not cleaned, it will affect the performance of the LCD screen, and even corrode the electrode leads, causing the whole machine to be scrapped. Therefore, in the production process of LCD screens, the cleaning effect directly affects the reliability and yield of LCD screens. At present, the cleaning of liquid crystals is mainly to add penetrants, surfactants and other additives in water for cleaning. The wetting, emulsifying and dispersing effects of oil stains, coupled with the auxiliary effects of surfactants and other additives, are suitable for cleaning various oil stains, but its disadvantages are that it is diff...

If it is not cleaned, it will affect the performance of the LCD screen, and even corrode the electrode leads in severe cases, causing the whole machine to be scrapped

Therefore, in the production process of LCD screens, the cleaning effect directly affects the reliability and yield of LCD screens. At present, the cleaning of liquid crystals is mainly to add penetrants, surfactants and other additives in water for cleaning. The wetting, emulsifying and dispersing effects of oil stains, coupled with the auxiliary effects of surfactants and other additives, are suitable for cleaning various oil stains, but its disadvantages are that it is difficult to clean blind holes, and the cleaning solution cannot be recovered and causes a lot of waste. Wastewater containing chemical active agents and dirt is directly discharged without treatment, which seriously pollutes the environment, so sewage treatment facilities must be added, which also greatly increases the production cost of liquid crystal
