Liquid crystal display cleaning device

Abstract

The invention relates to cleaning devices by using liquid, and discloses a liquid crystal display cleaning device. The liquid crystal display cleaning device comprises a cleaning groove and a drivingmechanism, transferring rollers are arranged at the bottom of the cleaning groove, and baffles are arranged in the cleaning groove and divide the cleaning groove into a plurality of chambers; a plurality of cleaning liquid storage cavities are formed below the cleaning groove, and the cleaning liquid storage cavities communicate with the cleaning groove; pistons capable of performing reciprocatingsliding along the cleaning liquid storage cavities are arranged in the cleaning liquid storage cavities, and through holes for passing a liquid crystal display are formed in the upper ends of the baffles; the driving mechanism comprises a stepping motor, a crank and a connecting rod, and the crank, the connecting rod and the pistons form a crank sliding block mechanism; and a starting switch is electrically connected to the stepping motor, pressing switches electrically connected with the stepping motor are arranged on the side walls of the through holes, when the starting switch is pressed,the stepping motor is started, when the pressing switches are pressed, the stepping motor stops to work. The liquid crystal display can be moved forward always through the transferring rollers and pass through different cleaning liquid, and thus the liquid crystal display is not required to be transferred among different equipment.

Description

technical field [0001] The invention relates to a liquid cleaning device, in particular to a liquid crystal screen cleaning device. Background technique [0002] Liquid crystal is a kind of substance with special properties. It maintains the unique characteristics of crystals that can be arranged in three-dimensional space within a certain range in a liquid state. The liquid crystal material used on the liquid crystal screen is an organic compound with structures such as cholesteryl ester, cyanobiphenyl, and phenylcyclohexane. After the liquid crystal material is encapsulated between two pieces of conductive glass, there will always be excess liquid crystal material remaining around it. If it is not cleaned, it will affect the performance of the liquid crystal screen. In severe cases, the electrode leads will even be corroded, causing the whole machine to be scrapped. Therefore, in the production process of LCD screens, the cleaning effect directly affects the reliability a...

Problems solved by technology

In order to ensure the cleanliness of the liquid crystal screen after cleaning, the liquid crystal screen is cleaned sequentially with a variety of cleaning liquids, which can more effectively remove the residual liquid crystals. However, in the existing cleaning device, different cleaning liquids need to be injected into different equipment In order to avoid the cleaning liquid mixing with each other; therefore, the LCD screen needs to be transferred repeatedly between devices, which increases the complexity of cleaning
