Specifically, crystal silicon battery screen printing device still includes canceling release mechanical system, and scraper mechanism 1 sets up on canceling release mechanical system, and canceling release mechanical system is used for resetting the scraper mechanism 1 to the initial position after accomplishing once printing to subsequent printing is convenient for.
Further, the reset mechanism comprises a lifting component and a translation component, the lifting component is used for lifting the scraper mechanism 1 between the printing plane and the reset plane, the reset plane is higher than the printing plane, and the scraper mechanism 1 is lifted from the printing plane to the reset plane after printing is finished; the translation assembly is used for translating the scraper mechanism 1 arranged on the reset plane to the initial position along the direction opposite to the printing direction so as to reset the scraper mechanism 1.
The reset scraper mechanism 1 is lowered to the printing plane from the reset plane through the lifting assembly for the next printing. It is worth mentioning that the printing of the doctor mechanism 1 can also be driven by a translation assembly, and the doctor mechanism 1 lowered to the printing plane is driven by the translation assembly to move the printing in the printing direction. The structure of the lifting assembly and the translation assembly can be set by those skilled in the art according to actual needs, as long as the lifting and the moving of the scraper mechanism 1 can be realized, and is not specifically limited herein.

Preferably, the nozzle assembly is disposed at an angle to the screen 100 and towards the rear of the printing direction to reduce the influence of the paste ejected through the nozzles on the printing of the squeegee assembly. The included angle between the nozzle assembly and the screen 100 may be set according to the installation height of the nozzle assembly and the spraying distance of the nozzle assembly, and is not particularly limited herein.
