Description

TECHNICAL FIELD

[0001] The utility model relates to the related technical field of silk screen printing especially, a lifting loadable type screen printing plate fixture of roller structure. BACKGROUND

[0002] The silk screen printing technology has been continuously improved from material to process since its origin in the 19th century, and is currently widely used in screen printing in the photovoltaic industry. The silk screen printing is to form positive and negative electrodes and back electric field on the front and back of the cell by printing and sintering, and then to complete the whole process of solar cell photoelectric conversion by outputting the photo-generated electricity through the external light path.

[0003] The silk screen printing technology uses the basic principle that the electrode part of the silk screen is transparent to the paste, and the non-electrode part is not transparent to the paste. When the printing blade moves along the silk screen, the paste is pressed into the mesh hole, and the blade produces shearing action on the paste. The paste has thixotropy, and its viscosity rapidly decreases under the shearing stress of the blade. At the moment when the blade contacts the silicon wafer, the paste in the mesh hole also contacts the silicon wafer. After the blade sweeps across the silk screen, the silk screen is quickly reset by the elastic force and the silicon wafer is separated from the contact. At this time, the paste in the mesh hole is subjected to the adhesion force of the silicon wafer and the gravity on the one hand, and the adhesion force of the silk screen on the other hand. However, since the viscosity of the paste is very low at this time, the force of the silk screen on the paste is much smaller than the downward force. Therefore, during the elastic return of the silk screen, the paste in the mesh hole is transferred to the silicon wafer.

[0004] The wide application of the silk screen printing technology in the photovoltaic industry has led to a sharp increase in the demand for screen printing plates, and the complexity and fineness of screen printing patterns have also been greatly improved. Therefore, laser processing technology has been widely used in the processing of silk screen patterns.
