b) transferring the cast-weld molds, wherein while the cast-weld molds are conveyed in the third step, one group of cast-weld molds 30 finish lead dipping at the corresponding lead dipping units 20 and are driven by the positioning slide carriages 52 to be transferred to the cast-weld units 10;
c) performing plate group cast welding, wherein the jacking assembly 31 drives the cooling circulation assembly 32 and the cast-weld mold 30 to jack until lead liquid in the cast-weld mold 30 is in contact with a plate group at the bottom of the storage battery pack 101, and at the moment, cooling water in the box body 321 cools the cast-weld mold 30 to complete cast welding;
at this time, the other group of cast-weld molds 30 synchronously complete lead dipping in the lead dipping unit 20 and wait for conveying;
fifthly, blanking transmission, wherein the linear transmission unit 40 carries the storage battery pack 101 subjected to cast welding to be linearly transmitted to a blanking station 203;
and step six, blanking, namely turning the blank to a positive state by the blanking manipulator 7, placing the blank on the output mechanism 6, and continuously transmitting and outputting the blank backwards.
