Efficient silicon wafer printing machine

Abstract

The invention relates to the technical field of silicon wafer production equipment, in particular to an efficient silicon wafer printing machine. The efficient silicon wafer printing machine comprises a rack and a workbench rotationally arranged on the rack. A conveying belt used for conveying silicon wafers is arranged on the workbench. An adjusting plate is rotationally arranged on the workbench and corresponds to the conveying belt. An air cylinder used for driving the adjusting plate to rotate is arranged on the rack. The stretching-out end of the air cylinder is in threaded connection with an adjusting nut. An ejector rod is rotationally arranged on the adjusting nut. When the efficient silicon wafer printing machine is used, the adjusting nut is controlled, the contact distance between the ejector rod and the adjusting plate can be adjusted, and therefore the rotating angle of the adjusting plate is changed so as to achieve silicon wafer fast locating, and the silicon wafer locating efficiency is improved; and the problems that in an existing photovoltaic solar efficient silicon wafer printing machine, silicon wafer locating is inaccurate, the locating efficiency is low, the printing effect is not good enough, the printing precision is not high enough, and the production efficiency is low are solved.

Description
