Abstract

The invention relates to the technical field of silk-screen printing equipment, particularly to a system and method for aligning silk-screen printing. A silk screen plate and a lifting table are arranged on a silk-screen printing machine, a fixture is arranged on the silk screen plate, an XYR micro-motion platform is arranged on the lifting table, a vacuum chuck is arranged on the XYR micro-motion platform, the vacuum chuck is used for adsorbing a printing stock, and the printing stock corresponds to a position under the silk screen plate; a first positioning mark is arranged on the silk screen plate, and a second corresponding positioning mark is arranged on the print stock; the fixture is used for regulating the height and the two-dimension plane coordinates, which are relative to those of the silk screen plate, of an imaging and amplifying camera, the XYR micro-motion platform is used for regulating the two-dimension plane coordinates of the print stock and rotating the print stock, the lifting table is used for regulating the height of the printing stock, the first positioning mark on the silk screen plate and the second corresponding positioning mark on the print stock are collected by the imaging and amplifying camera, and the position and the direction of the printing stock are regulated through the XYR micro-motion platform and the lifting table, so that the first positioning mark and the second positioning mark are accurately aligned, and the effect that a blanking region of the printing stock and a pattern on the silk screen plate are accurately aligned is achieved.

Description

technical field [0001] The invention relates to the technical field of screen printing equipment, in particular to a screen printing alignment system method, which realizes micron-level alignment accuracy. Background technique [0002] Glass paste bonding has the advantages of simple thermocompression bonding process, a wide range of bonding materials, no special requirements on the flatness of the bonding surface, and can contain metal leads. It is used in micro gyroscopes, RF sensors, field emission devices, It has been widely used in the packaging of pressure sensors and the like. The glass paste bonding process includes screen printing of glass paste, pre-sintering and thermocompression bonding. Among them, the quality of screen printing and the level of alignment accuracy directly determine the success rate of glass paste bonding. [0003] In the screen printing process, the pre-printed glass paste must be accurately printed to the designated position of the patterned...
