Solar battery main grid mask plate

A solar battery main grid mask plate is composed of bolts (200), a base plate (201), a cover plate (202) and mask strips (203). The solar battery main grid mask plate is horizontally arranged. The base plate (201) is arranged at the lower portion. The cover plate (202) is arranged on the base plate (201). The mask strips (203) are arranged inside the middle area on the cover plate (202). The number of the mask strips (203) is equal to that of main grids needed when a solar battery forms a mask. Base plate latch holes and cover plate latch holes are symmetrically distributed in the sides of the base plate (201) and the cover plate (202) in the same direction. The bolts (200) are adopted for fixing the base plate and the cover plate through the base plate latch holes and the cover plate latch holes, so that the solar battery main grid mask plate forms a hinge structure capable of being opened and closed freely.
