The invention provides a printing device for a solar cell. The printing device comprises a printing platform, a conveying device, a feeding deviation correcting device and a printing machine head device. The printing platform is used for bearing silicon wafers and can move to drive the silicon wafers to sequentially pass through an input position, a printing position and an output position. The input position can accommodate a plurality of silicon wafers at the same time. The conveying device is used for inputting the silicon wafers to be printed to the input position of the printing platform and outputting the printed silicon wafers from the output position of the printing platform. The feeding deviation correcting device is used for grabbing the silicon wafers to be printed and adjusting the positions of the silicon wafers to be printed so that the multiple silicon wafers to be printed can be arranged at the input position according to the set relative positions. The printing machine head device is used for adjusting the relative positions of the multiple silicon wafers to be printed and printing the silicon wafers located at the printing position. Printing of the plurality of silicon wafers spliced into a large-size cell piece can be completed through a single printing process, the production efficiency is improved, and the manufacturing cost is reduced.
Description
technical field [0001] The invention belongs to the technical field of solar cell manufacturing, and more specifically relates to a printing device for solar cells. Background technique [0002] In the production process of solar cells, the silicon wafer as a carrier needs to be transported between the various components of the production system, so as to realize the detection of the silicon wafer, surface etching, screen printing, etc. circuit of solar cells. [0003] The printing device is a device used to print circuits on silicon wafers. With the development of solar cells towards larger size, the size of silicon wafers is required to be larger and larger, but the thickness of larger silicon wafers is difficult to meet the requirements of solar cells. In the related art, a plurality of small-sized printed silicon wafers are spliced to form large-sized solar cells, but the huge number of processed and printed silicon wafers reduces production efficiency and increases p...
