Description

TECHNICAL FIELD

[0001] The utility model relates to display screen production technical field, more specifically, especially relates to a double -sided door vacuum defoaming machine. BACKGROUND

[0002] In the production process of display screen, there are several times of laminating process, after the completion of soft paste and hard paste, bubbles will be generated between two different laminating media. The defoaming of display screen is usually completed by defoaming machine, and its principle is to eliminate the bubbles generated in the laminating process through temperature and pressure. With the development of flat panel display industry, the production process requires the equipment to realize the whole line automation, so the automation of defoaming process equipment is also essential. In the two processes of laminating and defoaming, laminating mainly plays the role of positioning and preliminary bonding, and there will be some bubbles remaining in the laminated surface in this process; and defoaming plays the role of extruding bubbles and strengthening the bonding effect.

[0003] The working process of the vacuum defoaming machine mainly includes the following steps: first, the material to be processed is placed in the heating cavity of the vacuum defoaming machine. The temperature in the heating cavity can be adjusted according to different materials and requirements; then, the door of the heating cavity is closed, and the vacuum pump is started to start pumping air. With the air being pumped away, the pressure in the heating cavity gradually decreases, forming a negative pressure environment. Under the negative pressure environment, the bubbles will gradually expand and separate from the material due to the pressure difference between the gas molecules in the material and the surrounding environment. At the same time, the temperature in the heating cavity also accelerates the movement and removal of the bubbles; then, the vacuum defoaming machine stops pumping and returns to normal pressure. At this time, most of the bubbles have been removed from the product, and the quality and appearance have been significantly improved; finally, the door of the heating cavity is opened, and the processed product is taken out. According to the needs, subsequent process treatment can also be carried out.

[0004] The conventional vacuum defoaming process needs to put the product into the defoaming machine, wait for it to rise in pressure and temperature, and then defoam. After the defoaming is completed, it needs to wait for the temperature and pressure to decrease before removing it for the next process. Not only does it need to wait for the product to warm up before it can be pressurized, but also the product needs to be cooled down before it can be defoamed again, which consumes a lot of waiting time.
