In the process of the stacking suction block 147 sucking the positive electrode sheet from the first storage frame 11 or sucking the negative electrode sheet from the second storage frame 12, the stacking suction block 147 squeezes and sucks the positive electrode sheet or the negative electrode sheet from the top, and the stacking suction block 147 drives the guide shaft 143 to slide upward in the guide hole 1461, and the guide shaft 143 compresses the first elastic member 144. The rebound force of the first elastic member 144 enables the stacking suction block 147 to maintain the pressing force on the positive electrode sheet or the negative electrode sheet, so that the stacking suction block 147 can smoothly suck the positive electrode sheet or the negative electrode sheet, while also avoiding the accident of the stacking suction block 147 damaging the positive electrode sheet or the negative electrode sheet. In addition, when the stacking transfer component 14 transfers the positive electrode sheet or the negative electrode sheet to the stacking platform component 13, the stacking suction block 147 sucks the positive electrode sheet or the negative electrode sheet, and the vibrating ejector pin 142 strikes the positive electrode sheet or the negative electrode sheet back and forth from the side, thereby avoiding the accident of the stacking suction block 147 sucking multiple positive electrode sheets or negative electrode sheets at a time, and ensuring the stability of the stacking transfer component 14 in transferring the positive electrode sheets and the negative electrode sheets one by one.

[0080] In one embodiment, if Figure 1 and Figure 3 As shown, the diaphragm feeding component 15 includes a diaphragm feeding roller 151, a diaphragm guide roller 152 and a pressure roller 153 rotatably mounted on the stack support block 145, the diaphragm feeding roller 151 is used to wind the diaphragm; the diaphragm guide roller 152 is mounted on the stack support block 145, and is used to guide the diaphragm released by the diaphragm feeding roller 151 to the stack component 13; the pressure roller 153 is mounted on the stack support block 145, and is used to roll the diaphragm on the stack component 13.

[0081] Specifically, the stacking drive 141 drives the stacking suction block 147 via the stacking support block 145. After the stacking suction block 147 transfers a positive electrode sheet or a negative electrode sheet to the stacking platform 13, the stacking drive 141 drives the diaphragm guide roller 152 via the stacking support block 145. The diaphragm guide roller 152 lays the diaphragm on the positive electrode sheet or the negative electrode sheet, and the pressing roller 153 presses the diaphragm from behind, thereby ensuring the smoothness of the diaphragm on the positive and negative electrode sheets. In this embodiment, the stacking mechanism 1 can complete the stacking of positive and negative electrode sheets, as well as the diaphragm, thereby improving the processing efficiency of the battery cell assembly 100.

[0082] In one embodiment, the lamination mechanism 1 further includes a cutter mounted on the lamination member 13, the cutter being used to cut the diaphragm between the diaphragm guide roller 152 and the lamination member 13. It is understood that after the electrode sheet and the diaphragm are laminated on the lamination member 13, the cutter cuts the diaphragm, thereby completing the battery cell assembly 100 consisting of the electrode sheet and the diaphragm on the lamination member 13. An external robot, etc., can then remove the battery cell assembly 100 from the lamination member 13.

[0083] In one embodiment, if Figure 5 As shown, the stacking component 13 includes a stacking platform lifting drive 131, a stacking platform body 132, a pressing drive 133 and a stacking platform pressing block 134; the stacking platform lifting drive 131 is connected to the stacking platform body 132; the pressing drive 133 is connected to the stacking platform pressing block 134, and is used to drive the stacking platform pressing block 134 to press at least one of the positive electrode sheet, negative electrode sheet and diaphragm on the stacking platform body 132.

[0085] Specifically, after the positive electrode sheet, the negative electrode sheet and the diaphragm are placed on the stacking platform body 132, the pressing drive 133 drives the stacking platform pressing block 134 to dock with the stacking platform body 132. The stacking platform pressing block 134 can press the positive electrode sheet, the negative electrode sheet and the diaphragm onto the stacking platform body 132 to avoid the positive electrode sheet, the negative electrode sheet and the diaphragm on the stacking platform body 132 from being scattered.

[0088] Among them, in the first feeding tray 31, there is a first pressing plate 37 between each of the two adjacent first aluminum-plastic films, and there is a first aluminum-plastic film between each of the two adjacent first pressing plates 37, so that the first pressing plate 37 can play the role of pressing the first aluminum-plastic film from above, avoiding the first aluminum-plastic film on the first feeding tray 31 from curling, wrinkling, etc. Similarly, in the second feeding tray 32, there is a second pressing plate 38 between each of the two adjacent second aluminum-plastic films, and there is a second aluminum-plastic film between each of the two adjacent second pressing plates 38, so that the second pressing plate 38 can play the role of pressing the second aluminum-plastic film from above, avoiding the second aluminum-plastic film on the second feeding tray 32 from curling, wrinkling, etc. The first suction cup assembly 353 includes a plurality of first suction cups installed at intervals on the material transfer support plate 352, and the second suction cup assembly 354 includes a plurality of second suction cups installed at intervals on the material transfer support plate 352.

[0089] Specifically, the transfer component 35 transfers the first aluminum-plastic film on the first feeding tray 31 to the clamping component 36.

[0090] In this embodiment, the battery top and side sealing mechanism 3 can encapsulate the first aluminum-plastic film and the second aluminum-plastic film into a bag body for accommodating battery cells. The battery top and side sealing mechanism 3 does not require a complete bag body to be provided externally, thereby reducing the manufacturing cost of the soft-pack battery. In addition, during the process of the transfer component 35 transferring the first and second aluminum-plastic films, the first pressing plate 37 is always pressed on top of the first aluminum-plastic film, thereby preventing the occurrence of curling, wrinkles, etc. during the transfer of the first aluminum-plastic film. The second pressing plate 38 is always pressed on top of the second aluminum-plastic film, thereby preventing the occurrence of curling, wrinkles, etc. during the transfer of the second aluminum-plastic film.
