Abstract

The invention discloses a screen printing machine, and relates to the field of solar silicon cell piece production equipment. The screen printing machine is used for manufacturing back surface fields, back electrodes and positive grid line electrodes. The screen printing machine comprises a rack. A printing platform and a printing device are arranged in the rack; an opening door is hinged to the rack; a humidifier is arranged in the rack; a humidification pipe is connected to the humidifier; the other end of the humidification pipe is arranged on the upper portion in the rack; a humidification inductor is connected to the printing platform; the signal output end of the humidification inductor is connected to a temperature and humidity controller of the humidifier. Due to the adoption of the design, when the humidity around the printing platform of the printing machine is reduced, the humidification inductor sends signals to ensure that the humidifier works to humidify the space of the printing machine in the rack, and accordingly the problem that because metal sizing agents become dry, the printing quality is affected is solved.

Description

technical field [0001] The invention relates to the field of solar silicon cell production equipment, in particular to a screen printing machine for producing back field, back electrode and positive grid line electrode. Background technique [0002] A screen printing machine is a device that uses the principle of screen printing to print metal paste onto solar silicon cells. The production line of solar silicon cells requires screen printing machines to continuously improve production capacity and printing quality. However, the metal paste in the existing screen printing machines is easy to dry, which affects the printing quality, thereby affecting the performance of silicon wafers. Contents of the invention [0003] The purpose of the present invention is to provide a screen printing machine capable of automatic humidification in order to overcome the deficiencies of the prior art. [0004] The object of the present invention is achieved like this: a screen printing mach...
