The diaphragm feeding roller 151 is used for winding the diaphragm; the diaphragm guiding roller 152 is mounted on the lamination support block 145 and is used for guiding the diaphragm released by the diaphragm feeding roller 151 to the lamination component 13; the pressing roller 153 is mounted on the lamination support block 145 and is used for rolling the diaphragm on the lamination component 13.

[0038] Specifically, the lamination driving member 141 drives the lamination suction block 147 to move through the lamination support block 145. After the lamination suction block 147 transfers a positive electrode sheet or a negative electrode sheet to the lamination component 13, the lamination driving member 141 drives the diaphragm guiding roller 152 to move through the lamination support block 145. The diaphragm guiding roller 152 lays the diaphragm on the positive electrode sheet or the negative electrode sheet, and the pressing roller 153 rolls the diaphragm from the rear, thereby ensuring the flatness of the diaphragm laid on the positive electrode sheet and the negative electrode sheet. In this embodiment, the lamination mechanism 1 can complete the lamination work of the positive electrode sheet, the negative electrode sheet, and the diaphragm, improving the processing efficiency of the battery cell assembly 100.

[0039] In one embodiment, the lamination mechanism 1 further includes a cutter mounted on the lamination component 13, and the cutter is used for cutting the diaphragm between the diaphragm guiding roller 152 and the lamination component 13. It can be understood that after the electrode sheet and the diaphragm are laminated on the lamination component 13, the cutter cuts the diaphragm, and thus the battery cell assembly 100 composed of the electrode sheet and the diaphragm is completed on the lamination component 13, and an external manipulator or the like can take away the battery cell assembly 100 from the lamination component 13.

[0040] In one embodiment, as Figure 5 shown, the lamination component 13 includes a lamination lifting driving member 131, a lamination body 132, a pressing driving member 133, and a lamination pressing block 134; the lamination lifting driving member 131 is connected to the lamination body 132; the pressing driving member 133 is connected to the lamination pressing block 134 and is used for driving the lamination pressing block 134 to press at least one of the positive electrode sheet, the negative electrode sheet, and the diaphragm on the lamination body 132.

[0041] Wherein, the lamination lifting driving member 131 and the pressing driving member 133 include but are not limited to air cylinders, hydraulic cylinders, screw nut assemblies, etc.; the lamination pressing block 134 is located on the side of the lamination body 132.

[0042] Specifically, after the positive electrode sheet, the negative electrode sheet, and the separator are placed on the stacking table body 132, the pressing material driving member 133 drives the stacking table pressing block 134 to dock with the stacking table body 132. The stacking table pressing block 134 can press the positive electrode sheet, the negative electrode sheet, and the separator tightly on the stacking table body 132, avoiding the accident that the positive electrode sheet, the negative electrode sheet, and the separator on the stacking table body 132 are scattered.

[0043] In one embodiment, as Figure 7 shown, the first feeding tray 31 is used to store the alternately stacked first aluminum-plastic films and the first pressing plates 37, and the second feeding tray 32 is used to store the alternately stacked second aluminum-plastic films and the second pressing plates 38; The transfer component 35 includes a material transfer driving assembly 351, a material transfer support plate 352, a first suction cup assembly 353, and a second suction cup assembly 354. The material transfer support plate 352 is installed at the output end of the material transfer driving assembly 351, and both the first suction cup assembly 353 and the second suction cup assembly 354 are installed on the material transfer support plate 352. The first suction cup assembly 353 is used to adsorb the first pressing plate 37 or the second pressing plate 38, the second suction cup assembly 354 is used to adsorb the first aluminum-plastic film that fits with the first pressing plate 37 or the second aluminum-plastic film that fits with the second pressing plate 38, and the first suction cup assembly 353 and / or the second suction cup assembly 354 are also used to adsorb the battery cell assembly 100.

[0044] Among them, in the first feeding tray 31, there is a first pressing plate 37 between adjacent two first aluminum-plastic films, and there is a first aluminum-plastic film between adjacent two first pressing plates 37. Thus, the first pressing plate 37 can play a role in pressing the first aluminum-plastic film from above, avoiding phenomena such as curling and wrinkling of the first aluminum-plastic film on the first feeding tray 31. Similarly, in the second feeding tray 32, there is a second pressing plate 38 between adjacent two second aluminum-plastic films, and there is a second aluminum-plastic film between adjacent two second pressing plates 38. Thus, the second pressing plate 38 can play a role in pressing the second aluminum-plastic film from above, avoiding phenomena such as curling and wrinkling of the second aluminum-plastic film on the second feeding tray 32. The first suction cup assembly 353 includes a plurality of first suction cups spacedly installed on the material transfer support plate 352, and the second suction cup assembly 354 includes a plurality of second suction cups spacedly installed on the material transfer support plate 352.

[0045] Specifically, the transfer component 35 transfers the first aluminum-plastic film on the first feeding tray 31 to the clamping component 36. During the process of transferring the first aluminum-plastic film, the first suction cup assembly 353 adsorbs the first pressing plate 37, the second suction cup assembly 354 adsorbs the first aluminum-plastic film, and the first pressing plate 37 presses above the first aluminum-plastic film; the transfer component 35 transfers the battery cell assembly 100 on the third feeding tray 33 to the clamping component 36. During the process of transferring the battery cell assembly 100, the first suction cup assembly 353 and / or the second suction cup assembly 354 adsorb the battery cell assembly 100; the transfer component 35 transfers the second aluminum-plastic film on the second feeding tray 32 to the clamping component 36. During the process of transferring the second aluminum-plastic film, the first suction cup assembly 353 adsorbs the second pressing plate 38, the second suction cup assembly 354 adsorb the second aluminum-plastic film, and the second pressing plate 38 presses above the second aluminum-plastic film; the clamping component 36 clamps the first aluminum-plastic film, the battery cell assembly 100 and the second aluminum-plastic film stacked together; the side-sealing component 34 seals three sides of the first aluminum-plastic film and the second aluminum-plastic film, so that the battery cell assembly 100 is located in the inner cavities of the first aluminum-plastic film and the second aluminum-plastic film.

[0046] In this embodiment, the top side-sealing mechanism 3 of the battery can package the first aluminum-plastic film and the second aluminum-plastic film into a bag body for accommodating the battery cells. The top side-sealing mechanism 3 of the battery does not require an externally provided complete bag body, reducing the manufacturing cost of the soft-pack battery. In addition, during the process of the transfer component 35 transferring the first aluminum-plastic film and the second aluminum-plastic film, the first pressing plate 37 always presses above the first aluminum-plastic film, thus avoiding phenomena such as curling and wrinkling during the transfer process of the first aluminum-plastic film. The second pressing plate 38 always presses above the second aluminum-plastic film, avoiding phenomena such as curling and wrinkling during the transfer process of the second aluminum-plastic film; the flatness of the first aluminum-plastic film and the second aluminum-plastic film ensures the sealing performance of the side-sealing of the first aluminum-plastic film and the second aluminum-plastic film, and ensures the quality of the soft-pack battery.

[0047] In one embodiment, as Figure 7 shown, the first pressing plate 37 is provided with a first through hole 371; the second suction cup assembly 354 passes through the first through hole 371 to adsorb the first aluminum-plastic film, or the second suction cup assembly 354 adsorbs the first aluminum-plastic film through the first through hole 371; the second pressing plate 38 is provided with a second through hole 381; the second suction cup assembly 354 passes through the second through hole 381 to adsorb the second aluminum-plastic film, or the second suction cup assembly 354 adsorbs the second aluminum-plastic film through the second through hole 381.

[0048] Wherein, the second suction cup assembly 354 can extend below the first pressing plate 37 through the first through hole 371. Thus, while the first suction cup assembly 353 adsorbs the first pressing plate 37, the second suction cup assembly 354 can adsorb the first aluminum-plastic film; the second suction cup assembly 354 can also suck the first through hole 371 into a vacuum state, so that the first aluminum-plastic film fits below the first pressing plate 37. Similarly, the second suction cup assembly 354 can extend below the second pressing plate 38 through the second through hole 381. Thus, while the first suction cup assembly 353 adsorbs the second pressing plate 38, the second suction cup assembly 354 can adsorb the second aluminum-plastic film; the second suction cup assembly 354 can also suck the second through hole 381 into a vacuum state, so that the second aluminum-plastic film fits below the second pressing plate 38.
