PURPOSE:To reduce the number of constant-volume electrolyte pouring pumps by lowering an electrolyte pouring hopper, bringing an electrolyte pouring nozzle into close contact with the upper surface of a plate group in a battery case, and on the other hand, supplying an electrolyte to the electrolyte pouring hopper from an electrolyte supply unit, and pouring the electrolyte in the electrolyte pouring hopper into the battery case. CONSTITUTION:After a case holder 3 passed a battery case supply unit 2, an electrolyte pouring hopper 19 is lowered, an electrolyte pouring nozzle 20 of the electrolyte pouring hopper 19 is inserted into a battery case a in a case holder 3 and brought into close contact with the upper surface of a plate group c. Since the internal space between the electrolyte pouring nozzle 20 and the plate group c is separated from the external space, the electrolyte pouring hopper 19 can store a large volume of electrolyte e supplied from electrolyte supply units 4, 5 in electrolyte pouring stations A1, A2. The pouring amount of electrolyte per injection can be increased, and the number of constant-volume electrolyte pouring pumps can be reduced. |
