The purpose of this design is that, because the plating solution sprayed from the nozzle 32 will be temporarily stored in the inner cavity 44, the height of the upper edge of the partition 46, i.e. the liquid level of the plating solution, is designed to be higher than the height of the lowest part of the blade roller 31, so that the upper surface of the photovoltaic product can be immersed in the plating solution to be fully contacted.

In order to further ensure that the surface of the photovoltaic product is kept dry when the photovoltaic product contacts the cathode assembly 1, the electroplating device in this embodiment is provided with external water-blocking rollers at the inlet end and/or the outlet end of the electroplating module. In fig. 1 to 5 of this embodiment, the external water blocking roller is not shown, and the structure of the external water blocking roller is substantially the same as that of the water blocking roller 2 in the electroplating module, and is only located at the inlet end side or the outlet end side of the electroplating module at the setting position and is installed on the rack 5. The built-in water-blocking roller 2 can be influenced by the electroplating solution in the box body 4 to a certain extent, and the external water-blocking roller can obviously reduce the influence of the part.
