When the movable flap 322 is pivoted towards the fixed flap 321, a pushing force will be exerted on the electrode foil 8 which is directed outwards, perpendicular to the upper surface of the movable flap 322.

Since the weight of the electrode sheet 8 is low and the surface area is large, the electrode sheet 8 is released on the folded groove 323, the electrode sheet 8 is subjected to large air resistance and risks drifting away sideways, and the suction nozzle 351 is arranged at the bottom of the first groove 3231, and the suction nozzle 351 will create a low-pressure area below, so that the electrode sheet 8 is sucked in the first groove 3231. In addition, since the electrode sheet 8 has a certain elasticity, when the movable folding plate 322 is restored, the limit of the electrode sheet 8 in the direction perpendicular to the fixed folding plate 321 is lost, the electrode sheet 8 risks to be popped out due to the self elasticity relaxation, and at this time, the suction nozzle 351 can suck and fix the electrode sheet 8 in the direction perpendicular to the fixed folding plate 321, thereby facilitating the next operation.

Referring to fig. 6, the welding device 4 includes an ultrasonic welding machine 41 fixedly mounted on the frame 1, a rotating table 42 rotatably mounted on the frame 1, a plurality of welding tables 43 provided on the rotating table 42, and a pressing mechanism 44 for pressing the electrode sheet 8 against the welding tables 43.

With continued reference to fig. 6, the welding table 43 is provided with a welding groove 431 for accommodating the electrode sheet 8, and the shape of the welding groove 431 is adapted to the shape of the folded electrode sheet 8. In the present embodiment, the rotating table 42 is disposed in a square shape, and the number of the welding tables 43 is four and disposed on four sides of the rotating table 42, respectively. Wherein, the welding table 43 under the welding head 411 of the ultrasonic welding machine 41 corresponds to a welding station, and the two sides thereof are respectively a feeding station and a discharging station. The rotating table 42 moves the welding table 43 loaded with the unwelded electrode sheet 8 under the welding head 411 of the ultrasonic welding machine 41 by rotating, and moves the welding table 43 loaded with the welded electrode sheet 8 under the transfer device 7. Through dispersing the three processes of feeding, processing and discharging of the rotating table 42 on different stations, the rotating table 42 controls the welding table 43 to move on each station, and the processes are sequentially performed, so that the phenomenon that a plurality of processes are concentrated on the same welding table 43 is avoided, and the processing efficiency of the welding device 4 is effectively improved.

With reference to fig. 6, the pressing mechanism 44 includes a pressing block 441 disposed above each welding station 43, a pressing cylinder 445 disposed below the feeding station and the discharging station, respectively, a limiting block 442 disposed at the bottom of the rotating station 42, a pressing link 443 disposed through the rotating station 42 and fixedly connecting the pressing block 441 and the limiting block 442, and an elastic member 444 sleeved outside the pressing link 443 and connecting the limiting block 442 and the bottom of the rotating station 42. In this embodiment, the elastic member 444 is a compression spring, and the pressing cylinder 445 is fixedly mounted on the frame 1 and the piston rod is vertically disposed upward. When the pressing cylinder 445 pushes the pressing block 441 to move upwards, the transfer device 7 places the electrode sheet 8 on the welding table 43, when the piston rod of the pressing cylinder 445 contracts again, the limiting block 442 moves away from the rotating table 42 under the action of the elastic piece 444, and at the moment, the pressing block 441 moves towards the rotating table 42 and abuts against the electrode sheet 8.

During operation, a piston rod of the pressing cylinder 445 below the feeding station pushes the pressing block 441 to move upwards, the transfer device 7 places the electrode sheet 8 in the welding groove 431 of the welding table 43 on the feeding station, the piston rod retracts, and the elastic piece 444 resets to enable the pressing block 441 to press the electrode sheet 8 in the welding groove 431. The rotating table 42 then rotates the welding table 43 under the welding head 411 of the ultrasonic welding machine 41. The welding head 411 of the ultrasonic welding machine 41 descends to abut on the electrode sheet 8, and welds both ends of the electrode sheet 8 together. After welding, the rotating table 42 drives the welding table 43 to rotate to the discharging station, and after the piston rod of the pressing cylinder 445 lifts up the pressing block 441, the second set of transfer device 7 transfers the electrode sheet 8 on the discharging station to the stamping device 5 for processing.

Referring to fig. 7, the stamping device 5 includes a stamping cylinder 51 fixedly mounted on the frame 1, a stamping block 52 fixedly connected to a piston rod of the stamping cylinder 51, and a stamping table 53 disposed on the frame 1, wherein a stamping groove 531 for accommodating the electrode sheet 8 is disposed on the stamping table 53, the size and shape of the stamping groove 531 are adapted to the folded electrode sheet 8, and the stamping groove 531 is located on a moving path of the stamping block 52. When the electrode sheet 8 is welded, the surface is deformed by the abutment of the ultrasonic welding head, and the press block 52 and the press table 53 cooperate with each other to flatten the electrode sheet 8.

Referring to fig. 8, the finished product storage device 6 includes a blanking rotor 61 mounted on the frame 1, and a plurality of blanking cartridges 62 mounted on the blanking rotor 61. The blanking rotating piece 61 is arranged in a cylindrical shape, and the bottom of the blanking rotating piece is rotatably connected with the frame 1 through a bearing. In this embodiment, the number of the blanking cartridges 62 is four and is uniformly arranged on the circumference of the top surface of the blanking rotor 61. The blanking cartridge 62 is arranged in a square tube shape, and the cross section of the blanking cartridge is matched with the shape of the electrode sheet 8. The blanking cartridge clip 62 is provided with a guide post 63 corresponding to the through hole on the electrode sheet 8 along the axial direction, and the guide post 63 is fixedly connected with the bottom of the blanking cartridge clip 62. The transfer device 7 continuously releases the electrode sheets 8 onto the blanking cartridge 62 located below the fourth adsorbing member 7444, and the electrode sheets 8 are sleeved on the guide posts 63 and fall along the inner cavity of the blanking cartridge 62. When the electrode sheets 8 are full of the inner cavity of the blanking cartridge clip 62, the blanking rotating piece 61 rotates to enable the blanking cartridge clip 62 to leave the lower part of the transfer device 7, and the adjacent empty blanking cartridge clips 62 move to the lower part of the transfer device 7, so that the blanking operation of the blanking cartridge clip 62 is realized without stopping.
