An embodiment of the invention provides a seal agent coating device, a coating method thereof and a display panel alignment method and relates to the technical field of display panel manufacturing. The seal agent coating device comprises a seal agent storage chamber, a seal agent cold curing chamber, a cutting device, a pressurizing device and a stop plate, wherein the seal agent storage chamber is used for storing liquid seal agents, the seal agent cold curing chamber with a bottom opening is positioned below the seal agent storage chamber, communicated with the seal agent storage chamber and used for curing internal seal agents, the cutting device is used for cutting solid seal agents in the seal agent cold curing chamber, the pressurizing device is used for enabling the seal agents in the seal agent storage chamber and the seal agent cold curing chamber to move downwards, the shape and the size of the cross section of the seal agent cold curing chamber are identical with those of a seal agent pattern to be formed, and the stop plate is used for opening or closing the opening. The seal agent coating device, the coating method thereof and the display panel alignment method can avoid the influence of low uniformity of seal agent coating on display effect in the prior art and are used for manufacturing display panels.
Description
technical field [0001] The present invention relates to the technical field of display panel manufacturing, in particular to a frame sealing glue coating device, a coating method thereof, and a box alignment method of a display panel. Background technique [0002] The development of liquid crystal display panels is changing with each passing day, and has become an indispensable part of people's lives. It is widely used in the field of display technology because of its large viewing area, uniform and compact size, low-voltage micro-power consumption, flat-panel structure, passive display, large amount of displayed information, easy colorization, no electromagnetic radiation, and long life. . [0003] Among them, the liquid crystal display panel manufacturing process needs to carry out the sealing glue coating process, the traditional sealing glue coating process, such as figure 1 As shown, the nozzle 10 operates above the color filter substrate 20 . Specifically, on the on...
