A blanking driving synchronous pulley 934 and a blanking driven synchronous pulley 935 are respectively arranged on the blanking driving shaft 932 and the blanking driven shaft 933. A blanking synchronous belt 936 is wound between the blanking driving synchronous pulley 934 and the blanking driven synchronous pulley 935. The blanking synchronous belt 936 is fixedly connected to the pole piece suction nozzle module 92 through a connecting block. The output end of the blanking driving motor 931 is connected to one end of the blanking driving shaft 932 and can drive the blanking driving shaft 932 to rotate. The blanking driving shaft 932 can drive the blanking synchronous belt 936 to operate and further drive the pole piece suction nozzle module 92 to move on the blanking conveying guide rail 911.It further includes a receiving box module 94 for supporting use; the receiving box module 94 includes a box body 941, a material supporting plate guide rod 942 and a box connecting rod 943. A material supporting plate lifting screw rod 944 and a material supporting plate lifting motor 945 are arranged at the lower end of the box connecting rod 943. The material supporting plate lifting motor 945 is connected to the material supporting plate lifting screw rod 944 through a synchronous belt device and can drive the material supporting plate lifting screw rod 944 to rotate. The screw nut of the material supporting plate lifting screw rod 944 is connected to the lower end of the material supporting plate guide rod 942. A material supporting plate 946 is arranged at the upper end of the material supporting plate guide rod 942. The material supporting plate 946 can enter the inside of the box body 941 from the bottom of the box body 941 to support the pole pieces in the box body 941. Specifically, mounting plates are arranged at both ends of the box connecting rod 943. Both ends of the material supporting plate lifting screw rod 944 are installed on the two mounting plates through bearings. The material supporting plate guide rod 942 passes through the upper mounting plate. The synchronous belt device includes a driving synchronous pulley arranged at the output end of the material supporting plate lifting motor 945, a driven synchronous pulley arranged at the lower end of the material supporting plate lifting screw rod 944 and a synchronous belt wound between the driving synchronous pulley and the driven synchronous pulley. When implementing the present invention specifically, when the die-cut pole pieces are sent to a preset position by the belt, the blanking driving component drives the pole piece suction nozzle module 92 to move along the blanking conveying guide rail 911 to a suitable position. After moving in place, the suction nozzle lifting driving cylinder 921 drives the negative pressure suction nozzle 920 to descend close to the pole piece. At this time, the vacuum generator 926 provides vacuum for the negative pressure suction nozzle 920, and the negative pressure suction nozzle 920 adsorbs the pole piece. After the pole piece is adsorbed, the suction nozzle lifting driving cylinder 921 drives the negative pressure suction nozzle 920 and the pole piece to rise a preset height. After rising in place, the blanking driving component drives the pole piece suction nozzle module 92 and the pole piece to move a suitable distance along the blanking conveying guide rail 911, so that the pole piece is just located above the receiving box module 94 that needs to receive materials. At this time, the suction nozzle lifting cylinder 921 drives the negative pressure suction nozzle 920 and the pole piece to descend a suitable height. After knowing that the pole piece is close to the material supporting plate 946 inside the receiving box module 94, the vacuum generator 926 cuts off the vacuum source of the negative pressure suction nozzle 920, and the pole piece falls from the negative pressure suction nozzle 920 onto the material supporting plate 946. Since the pole piece is released from a position very close to or even close to the material supporting plate 946, the pole piece will not shift in position and will not be damaged by collision. After the negative pressure suction nozzle 920 places the pole piece into the receiving box module 94, the negative pressure suction nozzle 920 resets and performs the next material suction operation. Under the combined action of the material supporting plate lifting motor 945 and the material supporting plate lifting screw rod 944, the material supporting plate 946 descends a distance equal to the thickness of one pole piece. After each time the number of pole pieces supported on the material supporting plate 946 increases by one, the material supporting plate 946 descends a distance equal to the thickness of the pole piece downward, always ensuring that the discharging position of the negative pressure suction nozzle 920 remains consistent.
