Rectilinear transmission type crystalline silicon solar cell printer with two sets of printing tables

Abstract

The invention provides a silicon wafer feeding and discharging and printing method adopting two sets of printing tables and applied to crystalline silicon solar cell electrode printing production equipment, and relates to a rectilinear transmission type crystalline silicon solar cell printer with two sets of printing tables. Through the method for alternatively and simultaneously completing silicon wafer feeding and discharging and printing with the two sets of printing tables, printing equipment achieves higher productivity within unit time; rectilinear motion units are adopted to translate the printing tables between a silicon wafer feeding and discharging station and a printing station, and accurate positioned printing of cells is realized by virtue of single-degree-of-freedom high repeatability positioning accuracy; by the same set of camera system, pre-printing and post-printing data analysis is performed on the same silicon wafer on the same feeding and discharging station, and various technological functions including printing accuracy, broken gate detection, screen technique life monitoring, secondary printing screen matching monitoring are realized.

Description

technical field [0001] The silicon wafer transfer positioning method proposed by the invention is applied in the field of crystalline silicon solar cell electrode printing and production, and is suitable for high-speed mass production printing of high-efficiency crystalline silicon solar cell electrodes with high requirements on printing accuracy and printing quality. Background technique [0002] At present, there are two types of conventional printing machines for crystalline silicon solar cells. One is a printing machine structure that uses a rotary table to realize loading and unloading and printing of silicon wafers; the other is a linear transmission structure that uses a belt to transfer silicon wafers to the printing table for printing. . [0003] Printing equipment using a rotating table, such as figure 1 As shown, the loading of the silicon wafer 6013 and the position collection of the silicon wafer can be completed on the table 603 at the same time, the printing ...
