Design And Implementation Of LCD Panel Cleaning System

With the vigorous development of LCD industry,LCD panel cleaning industry has emerged.In the production and manufacturing process of LCD panel,it is inevitable that there will be pollution due to various reasons,and the dirty LCD panel will not be able to use,especially in LCD industry.If the LCD panel is caused by the pollution and the brightness is not equal,it will cause material and economic success This waste,so the purpose of this paper is to design a liquid crystal panel cleaning system,so that the cleanliness of the liquid crystal panel to meet the production requirements.In this paper,according to the actual needs,starting with the three functional modules of transmission,shaping and cleaning,in the design of the transmission system,the automatic guided vehicle is designed Vehicle)transport and roller transport are two major modules.In the AGV transport module,image processing algorithms such as threshold segmentation and least square method are selected to realize the function of AGV.In the process of roller transport of LCD panel,infrared sensor is used to monitor the LCD panel in real time to obtain the real-time position of LCD panel.Then,the shaping module is designed before the LCD panel cleaning to Calibrate the position of the LCD panel,design the circuit and software of the integral system,and complete the function of shaping;finally,in the design of the cleaning system,dry ultrasonic cleaning is used for the LCD panel,which makes the submicron level dust on the LCD panel fall off by the joint action of high-speed air flow and ultrasonic,and the fallen dust is finally absorbed by the vacuum adsorption chamber,so as to achieve the cleaning effect Fruit.After the field equipment debugging and actual operation,the cleaning system designed in this paper can effectively clean the dust on the LCD panel,to a certain extent,improve the production quality of the LCD panel.
