Abstract

The invention relates to Frit glue printing equipment and method. A worktable is used for placing glass to be printed with glue, a glue printing mechanism is arranged above the worktable, and a sealing ring is used for sealing the upper surface of the worktable and the lower portion of the glue printing mechanism; a body of the glue printing mechanism is of a structure defined by side plates and provided with upper and lower openings, a screen is connected to the opening in the lower end of the body of the glue printing mechanism, and a movable plate is matched with the interior of the body ofthe glue printing mechanism and is movably connected to the inner wall of the body of the glue printing mechanism; a compression cavity is a space defined by the inner wall of the body of the glue printing mechanism, the upper surface of the screen and the lower surface of the movable plate; an air inlet is formed in the body of the glue printing mechanism, the air inlet is used for guiding compressed air into the compression cavity, and a glue scraping assembly is arranged in the compression cavity and is used for scattering Frit glue into screen holes of the screen. The Frit glue printing equipment is used for glue printing, so that the heights of the Frit glue at all positions are coincident, and the product stability is improved further.

Description

technical field

[0001] The invention relates to the field of Frit offset printing, in particular to a Frit offset printing equipment and method. Background technique

[0002] As a new display technology, AMOLED has the advantages of wide color gamut, low power consumption, thin thickness and flexibility. Since the organic light-emitting material is easily corroded by water and oxygen and deteriorates, the encapsulation technology for isolating water and oxygen is particularly important. Frit glue packaging is widely used as a mature packaging technology.

[0003] Such as figure 1 As shown, the printing process of the traditional Frit glue is as follows: the Frit glue on the screen is evenly dispersed on the screen through the scraper 01, and then a certain pressure is applied through the rubber scraper 02 to squeeze the Frit glue and print it on the glass through the mesh. . Due to the poor levelness of the squeegee itself or the uneven pressure applied, there are differ...
