Water film protection device

The utility model relates to the technical field of solar cell manufacturing, in particular to a water film protection device, which comprises a frame body and a water film, an inlet of the spraying device is connected to the spraying liquid storage device through a spraying pipeline, and an outlet of the spraying device faces the to-be-sprayed object; the supporting device is arranged on one sideof the spraying pipeline and comprises a first fixing plate arranged on the frame body and a second fixing plate connected with the first fixing plate and used for fixing the spraying device. According to the utility model, the problem that the edge of the silicon wafer is easily etched less or over due to the deviation of the amount of water sprayed by the water pump each time in the prior art is solved. 本实用新型涉及太阳能电池片制造技术领域，具体涉及一种水膜保护装置，包括：架体，待喷淋物置于所述架体上；至少一组喷淋装置，所述喷淋装置的进口通过喷淋管路连接至喷淋液储存装置，所述喷淋装置的出口朝向所述待喷淋物设置；支撑装置，设于所述喷淋管路的一侧，包括设置在所述架体上的第一固定板和与所述第一固定板连接，用于固定所述喷淋装置的第二固定板。本实用新型解决了现有技术中水泵每次喷涌出的水量有偏差，容易造成硅片边缘少刻或者过刻的问题。
