Screen printing machine

Abstract

The invention discloses a screen printing machine. The screen printing machine comprises a bottom plate. The bottom plate is sequentially provided with an inlet slice conveying mechanism, a rotating platform group and an outlet slice conveying mechanism. The rotating platform group comprises a rotating frame and a rotation drive mechanism driving the rotating frame to do rotating movement. A plurality of silicon wafer placement conveying platforms are arranged on the rotating platform in the circumferential direction. An inlet slice detection positioning mechanism, a screen printing device andan outlet slice detection mechanism are arranged on the circumferential side of the rotating frame, the silicon wafer placement conveying platforms sequentially move to the positions below the detection positioning mechanism, the screen printing device and the outlet slice detection mechanism in the rotating process. The rotating platform assembly design is simplified, the rotating platform and the silicon wafer placement conveying platforms are integrally designed, the assembly installation space is reduced, the total weight is reduced, the assembly weight is drawn close to the center of therotating platform so that the rotation inertia can be reduced, the printing precision is improved, the silicon wafer placement conveying platforms carry out conveying in a non-contact manner, the conveying power is stable, and the precision is good.

Description

technical field [0001] The invention relates to the field of screen printing, in particular to a screen printing machine. Background technique [0002] The rotating table and roll paper base of the existing equipment are designed separately, the overall weight is relatively large, and the distribution is far from the center of the rotating table, the inertia is large when rotating, which affects the overall printing accuracy; the roll paper group is transmitted by a synchronous belt and a synchronous wheel, Not only the overall cost is high, but also due to the high frequency of operation, the wear and tear is relatively large, and because of its compact structure, maintenance is relatively difficult. Contents of the invention [0003] The technical problem solved by the invention is to provide a screen printing machine with compact structure and high printing progress. [0004] The technical solution adopted by the present invention to solve the technical problem is: a s...
