Heat press for a specified time.

(5) The double-layer lamination stacking mechanism 4 has a total of eight groups, and the laminated units that have been hot-pressed by the unit heat-pressing mechanism 3 are transported to the multi-layer stacking mechanism. First, the first transfer and stacking mechanism 43 of the double-layer lamination stacking mechanism 4 The lamination suction mechanism below absorbs the corresponding lamination unit, and then the first transfer and stacking mechanism 43 stacks the sucked lamination unit on the adjacent lamination unit to form a double-layer lamination unit; eight double-layer lamination stacking mechanisms 43 After the double-layer stacking is completed at the same time, the eight double-layer lamination units are transported to the bottom of the four four-layer lamination stacking mechanisms 5, and the grasping mechanism below the second transfer stacking mechanism 53 of the four-layer lamination stacking mechanism grabs the corresponding double-layer stacking units. Laminate the sheet unit, then the second transfer and stacking mechanism 53 stacks the captured double-layer laminated unit on the adjacent double-layer laminated unit through the second slide rail 52, forming four four-layer laminated units; four four-layer laminated sheets The unit is transported below the two eight-layer lamination stacking mechanisms 6, and the third transfer and stacking mechanism 63 of the eight-layer lamination stacking mechanism 6 slides the captured four-layer lamination unit to the adjacent four-layer lamination unit through the third slide rail 62 above and stacked on the adjacent four-layer lamination unit to form an eight-layer lamination unit.

The four-layer lamination superposition mechanism 5 has the same structural components as the eight-layer lamination superposition mechanism 6. The four-layer lamination superposition mechanism 5 has four groups in total, and the eight-layer lamination superposition mechanism 6 has two groups in total.

(6) The lamination manipulator 701 grabs the eight-layer lamination unit on the conveying line 8 and puts it into the synthesis station of the output logistics line 9, accumulatively placing two eight-layer lamination units. The detector fixed at the front end of the second diaphragm transfer mechanism 713 checks whether the laminated unit at the stacking position is missing, and the missing unit is supplemented by the second pole piece transfer mechanism 722 and the second diaphragm transfer mechanism 713, and then the second The diaphragm transfer mechanism 713 and the second pole piece transfer mechanism 722 respectively place a layer of diaphragm and pole piece to reach the number of layers required by a single cell.

(7) The battery core passes through the second lamination unit heat-pressing mechanism 731 that reaches the set temperature, and completes the overall heat-pressing under the set pressure and temperature. The battery cells that have completed the overall hot pressing are transported to the diaphragm wrapping mechanism 741, which is composed of a turntable, a diaphragm unwinding mechanism, a diaphragm cutting mechanism, a diaphragm attaching mechanism, and a tape sticking mechanism. A tray for fixing the batteries is set on the turntable, and the turntable rotates to bring the batteries to the diaphragm attachment mechanism to complete the outer diaphragm attachment action. After attaching the diaphragm, it rotates to the tape attachment mechanism to complete the adhesive action. At this point, the battery cell assembly is completed, and it is transported to the next process by the conveyor line.

The utility model can realize the separate assembly of the multi-station positive and negative plates and the diaphragm through the lamination unit forming mechanism, and then integrate them into a lamination unit, and then use the multi-layer lamination superposition mechanism to stack multiple times to reach the designed number of layers to form an electric core; the utility model The new type breaks the upper limit of the beat of the traditional lamination equipment, the equipment efficiency is higher, and it has advantages in the processing of NG products than the traditional winding batteries, and it can realize flexible switching and is suitable for various types of pole piece specifications. The use of multi-station stacking, loading and unloading logistics circulation, and conveying lines has greatly reduced the manpower requirements for stacked battery manufacturing equipment.

The above-mentioned embodiments are only described to the preferred implementation of the utility model, and are not limited to the scope of the utility model. Various modifications and improvements made should fall within the scope of protection determined by the claims of the utility model.
