The two picking mechanisms 10, the third solder strip drawing mechanism 24 and the fourth solder strip drawing mechanism 25 alternately stack the battery pieces and the solder strip sections on the conveying belt 34 until the stacking of the predetermined number of battery pieces is completed.
After stacking of a predetermined number of battery plates is completed, the stepping platform 32 is stepped towards the fixed platform 33 to return, and the conveying belt 34 integrally conveys the stacked battery plates and the welding belt sections to the welding station.
Next, the stepping platform 32 is again stepped away from the fixing platform 33, and stacking of a predetermined number of battery pieces of the next batch is started.
By providing the stepping platform 32 capable of moving in steps toward or away from the fixed platform 33, the stepping platform 32 is stepped away from the fixed platform 33 by a predetermined distance each time stacking of one battery piece is completed in the battery piece stacking process. In this way, it can be ensured that after the current battery piece is stacked, the conveying belt 34 at the position of the piece placing position is immediately restored to the idle-loading device, so as to smoothly stack the next battery piece.
Therefore, by adopting the welding and conveying device in the embodiment, in the feeding process, the conveying belt 34 does not need to step towards the welding station, and the predetermined number of battery pieces can be continuously fed onto the conveying belt 34, so that the conveying belt 34 can convey the predetermined number of battery pieces fed onto the conveying belt to the welding station synchronously, the heating consistency of each battery piece is ensured, and the welding effect is improved.

8. A stringer comprising the battery sheet feeding device, the ribbon pulling device, the welding conveying device, and the welding device according to any one of claims 1 to 7, wherein:
the battery piece feeding device is used for laying battery pieces to the welding conveying device;
the welding strip traction device is used for laying welding strip sections to the welding conveying device and enabling the welding strip sections to be stacked on the corresponding battery pieces;
the welding conveying device conveys the stacked battery plates and the welding strip sections to a welding station;
the welding device is arranged at the welding station and used for welding the stacked battery plates and the welding strip sections into a string.
9. The stringer according to claim 8, wherein said solder ribbon drawing means comprises a cutter mechanism, a first solder ribbon drawing mechanism, a second solder ribbon drawing mechanism, and a solder ribbon laying mechanism, wherein:
the first and second solder strip drawing mechanisms are configured to alternately grip the solder strip at a drawing station located in front of a cutting station and draw the gripped solder strip to a transfer station located in back of the cutting station, wherein:
when the first welding strip traction mechanism draws the clamped welding strip to the transfer station, the second welding strip traction mechanism clamps the welding strip at the traction station, and the cutter mechanism cuts off the welding strip at the cutting station to obtain a welding strip section;
when the second welding strip traction mechanism pulls the clamped welding strip to the transfer station, the first welding strip traction mechanism clamps the welding strip at the pulling station, and the cutter mechanism cuts off the welding strip at the cutting station to obtain the welding strip section;
the welding strip laying mechanism is used for clamping the welding strip which is pulled to the transfer station by the first welding strip pulling mechanism or the second welding strip pulling mechanism; and laying the obtained welding strip section on the welding conveying device.
10. The stringer according to claim 9, wherein said ribbon laying mechanism comprises a third ribbon pulling mechanism and a fourth ribbon pulling mechanism that alternately grip said ribbon from said transfer station and lay said ribbon segments onto said welding conveyor.
11. The stringer according to claim 9, wherein said solder ribbon pulling device further comprises a solder ribbon lifting mechanism disposed between said cutting station and said transfer station;
the welding strip lifting mechanism is used for lifting the welding strip pulled to the transfer station by the first welding strip pulling mechanism or the second welding strip pulling mechanism.
12. The stringer of any of claims 8-11, wherein said welding conveyor comprises a base, a stepping platform, a fixed platform, and a conveyor belt, wherein:
the stepping platform is movably connected to the base;
the fixed platform is fixedly connected to the base, the welding station is positioned on the fixed platform, and the upper surface of the fixed platform and the upper surface of the stepping platform are positioned on the same plane;
the conveying belt is arranged on the fixed platform and the stepping platform, the battery pieces and the welding belt sections are stacked on the conveying belt on the stepping platform, and the conveying belt is configured to convey the stacked predetermined number of battery pieces and welding belt sections to a welding station;
the stepping platform is configured to be capable of stepping towards or away from the fixed platform, and after each battery piece is stacked on the conveying belt, the stepping platform steps away from the fixed platform by a preset distance until the preset number of battery pieces are stacked on the conveying belt.
