At present, when the liquid crystal display screen is not well fitted, it is necessary to separate the glass panel of the liquid crystal display screen from the liquid crystal component. Most of the existing separation methods use the heating platform, and place one side of the glass panel of the liquid crystal display screen on the heating plate, so as to soften the optical glue between the glass panel and the liquid crystal module. First, the height of molybdenum wire must be carefully adjusted, and the second pair must be aligned with the optical glue The cover plate and liquid crystal are cut by moving the two ends of metal molybdenum wire back and forth by hand. In the process of cutting, if the force is not uniform, it is easy to break the wire. If you hold the molybdenum wire manually, it is easy to touch the broken glass or liquid crystal and cause damage. In this way, the labor intensity of workers is high, and the technical requirements for workers are very high, and the efficiency is low. There are optical glue residues on the glass panel and liquid crystal module after separation, and the residual optical glue cleaning strength is also very large.
Through the industrial refrigerator, the temperature in the freezing chamber is reduced, and the LCD screen to be separated is put into the low-temperature freezing chamber for a period of time. The optical glue between the glass panel and the liquid crystal module of the liquid crystal screen is solidified and brittle under the low temperature environment. Then, the glass panel and the liquid crystal module can be separated manually by taking out the liquid crystal screen. The operation is convenient and simple, and will not cause damage to the glass panel and liquid crystal module Damage, and there will be no residual glue on the glass panel and liquid crystal module.
