Problems solved by technology
[0004] The existing cleaning process has the following defects: 1. When cleaning, the existing fixture needs to be soaked in pure water for cleaning, and the position and surroundings clamped by the existing fixture cannot be completely cleaned, which will easily affect the coating effect; 2. Different Large and small display screens need to be clamped after adjusting the existing fixtures. The process is cumbersome and time-consuming

Embodiment Construction
[0041] In order to make the technical means, creative features, goals and effects achieved by the present invention easy to understand, the present invention will be further described below in conjunction with specific illustrations. It should be noted that, in the case of no conflict, the embodiments in the present application and the features in the embodiments can be combined with each other.
[0042] like Figure 1 to Figure 7 As shown, a coating process of a liquid crystal display, the specific steps are as follows:
[0043]Step 1. Blocking the vent hole: Use UV glue to seal the vent hole between the two pieces of liquid crystal glass, and then use a FUSION F300 ultraviolet light curing machine to cure the UV glue at a temperature of 70-80°C;
[0044] Step 2. Surface cleaning: Use a water-based surfactant to remove oil and dust on the glass surface, and then use ultrasonic vibration cleaning to clean the glass surface;

The invention relates to a coating process of a liquid crystal display, which includes the following steps: blocking the vent hole, cleaning the surface, polishing, cleaning, coating and packaging and conveying. When cleaning, the existing fixture needs to be immersed in pure water for cleaning. The position and surroundings clamped by the existing fixture cannot be completely cleaned, which will easily affect the coating effect. Displays of different sizes need to be clamped after adjusting the existing fixture , the process is cumbersome and complicated, and takes a long time. It can realize the function of fully cleaning both sides of the LCD screen before coating. It can be sucked according to the screens of different sizes without manual adjustment, and the position held by the strong suction cup can be cleaned. , to ensure that the two sides of the display screen are completely cleaned, the time is short, and it has the advantages of simple operation, low labor intensity and high work efficiency.
Description
technical field [0001] The invention relates to the field of liquid crystal display coating technology, in particular to a liquid crystal display coating technology. Background technique [0002] Liquid crystal display is a kind of flat panel display. It is used for the screen display of TV and computer. The advantages of the display are low power consumption, small size, and low radiation. The liquid crystal display uses a liquid crystal solution in two polarized materials, so that when the current passes through the liquid, the crystals will be rearranged to achieve the purpose of imaging. [0003] Coating treatment is required during the processing of the liquid crystal display, and surface cleaning, polishing, cleaning and coating of the liquid crystal display are required during the coating treatment. [0004] The existing cleaning process has the following defects: 1. When cleaning, the existing fixture needs to be soaked in pure water for cleaning, and the position ...
