Problems solved by technology

However, due to the large number of stacked pole pieces, the lamination process is completed by alternately stacking positive and negative pole pieces, which is extremely inefficient and takes a lot of time, which is not conducive to the high-efficiency production of battery cells. The speed of chip production is the main bottleneck of the whole production process

Embodiment 1

[0048] see Figure 1-Figure 12 , the battery cell stacker with wheel feeding in this embodiment includes two oppositely arranged pole piece feeding devices, a lamination table 4 for stacking pole pieces, and a diaphragm conveying device 3 for conveying diaphragms, The two pole piece feeding devices are respectively the positive pole piece feeding device 1 and the negative pole piece feeding device 2, and the positive pole piece feeding device 1 and the negative pole piece feeding device 2 are respectively arranged on the side of the diaphragm conveying device 3. On both sides, the lamination table 4 is arranged between the positive electrode sheet feeding device 1 and the negative electrode sheet feeding device 2 .

[0049] see Figure 1-Figure 4 , Figure 10-Figure 12 , the positive electrode sheet feeding device 1 and the negative electrode sheet feeding device 2 both include a rotating frame, a rotary drive mechanism 13 that drives the rotating frame to rotate intermitten...

Embodiment 2

[0085] see Figure 13-Figure 14 , The difference between this embodiment and Embodiment 1 is that the runners 37 of the rotating frame are arranged in a polygonal shape, for example, the runners 37 are arranged in an equal hexagon, and the storage seats on the rotating frame are correspondingly arranged six, Each storage seat is arranged on the side 38 of the runner 37 in one-to-one correspondence; at the same time, one end of each side 38 of the equihexagonal runner 37 is rotatably connected to the runner 37, and the other end can swing left and right, The telescopic drive mechanism in this embodiment is a rotation drive mechanism, and each side 38 corresponds to a rotation drive mechanism for independently driving each side 38 to rotate to realize the swing of the storage seat on the side 38 .

[0086] When working, in the pole piece feeding process, in order to allow the runner 37 to have enough space for rotation, the top material driving mechanism 39 is set on the pole pi...
