The rubber pressure head 32 is connected to the telescopic end of the first cylinder 31. The first transmission platform 36 is located to the upper left of the second transmission platform 4, and the second transmission platform 4 passes through the first transmission platform 36. Multiple hollow placement columns 34 are placed on the first transmission platform 36, and battery cell windings 35 are placed on each hollow placement column 34. The first sensor 33 is connected to the middle of the first transmission platform 36. A hollow hole is opened in the middle of the first transmission platform 36. The diameter of the hollow hole is smaller than the diameter of the hollow placement column 34 and slightly larger than the diameter of the battery cell winding 35.
[0021] like Figures 1-3 As shown, the compaction assembly includes a second sensor 41, a second cylinder 42, a suction head 43, a third sensor 44, a fourth sensor 45, a third cylinder 46, a compactor 47, and finished battery products 48. The second sensor 41 is connected to the upper left side of the second transmission platform 4, and the second sensor 41 is located directly below the first transmission platform 36. The second cylinder 42 is connected to the upper middle side of the second transmission platform 4, and the suction head 43 is connected to the telescopic end of the second cylinder 42. The third sensor 44 is connected to the middle of the second transmission platform 4, the fourth sensor 45 is connected to the right side of the second transmission platform 4, the third cylinder 46 is connected to the upper right side of the second transmission platform 4, and the compactor 47 is connected to the telescopic end of the third cylinder 46. Multiple finished battery products 48 are placed on the upper right side of the second transmission platform 4.
[0022] like Figure 1 , Figure 2 and Figure 4 As shown, the feeding assembly includes a receiving turntable 5, a servo motor 51, a third transmission platform 52, a diaphragm 53, a fourth transmission platform 54, and a positive electrode cover 55. A turntable support frame is placed on the right rear of the second transmission platform 4. The servo motor 51 is connected to the turntable support frame. The receiving turntable 5 is connected to the output shaft of the servo motor 51. The receiving turntable 5 has multiple placement slots. The third transmission platform 52 is placed behind the turntable support frame. Multiple diaphragms 53 are placed on the third transmission platform 52. The fourth transmission platform 54 is placed on the right side of the turntable support frame. Multiple positive electrode covers 55 are placed on the fourth transmission platform 54.
[0023] When using this utility model, first move the device to the lithium battery cell packaging area, then place the bottom-sealed hollow cylinder 2 for lithium battery packaging on the placement cylinder 1, and feed the placement cylinder 1 from the left side of the second transmission platform 4 onto the second transmission platform 4, so that the second transmission platform 4 transports the placement cylinder 1 with the bottom-sealed hollow cylinder 2. When the placement cylinder 1 is transported to the position of the second sensor 41, the second transmission platform 4 pauses briefly. While transporting the placement cylinder 1, place the cell winding 35 for lithium battery packaging on the hollow placement column 34, and feed the hollow placement column 34 with the cell winding 35 onto the first transmission platform 36, so that the first transmission platform 36 transports the hollow placement column 34 from front to back. When the battery is delivered to the hollow hole on the first transmission platform 36, the first sensor 33 detects an obstruction signal, causing the first transmission platform 36 to pause briefly. This causes the battery winding 35 on the hollow placement column 34 to fall down through the hollow hole onto the sealed hollow cylinder 2. Then, the first cylinder 31 on the support column 3 is activated, extending its telescopic end and causing the rubber pressure head 32 to move downwards. After passing through the hollow hole, the rubber pressure head 32 assists in aligning the falling battery winding 35 and pressing it into the sealed hollow cylinder 2. Then, the first cylinder 31 is activated again, causing the rubber pressure head 32 to reset. The second transmission platform 4 is then activated to continue operating, causing the placement cylinder 1 to move. When the placement cylinder 1 moves to the position of the third sensor 44, the second transmission platform 4 is stopped again. The third transmission platform 52 transports a single diaphragm 53 to a placement slot on the receiving turntable 5, while the fourth transmission platform 54 places a single positive electrode cover 55 into the next placement slot on the receiving turntable 5. Then, the servo motor 51 is activated, causing the receiving turntable 5 to rotate. When the placement slot containing the diaphragm 53 rotates to the position of the third sensor 44, the second cylinder 42 is activated, causing its extension end to extend, allowing the suction head 43 to move downwards to adsorb the diaphragm 53. Then, the extension end of the second cylinder 42 is retracted, lifting the diaphragm 53. The servo motor 51 is then activated again, causing the receiving turntable 5 to rotate 45 degrees, positioning the diaphragm 53 within the gaps of the receiving turntable 5. Finally, the extension end of the second cylinder 42 is retracted... The separator 53 is placed on the cell winding 35, and then the positive electrode cover 55 is placed on the separator 53 in the same way. By adjusting the starting interval between the second transmission platform 4 and the receiving turntable 5, the separator 53 and the positive electrode cover 55 can be alternately placed in the placement slots on the receiving turntable 5, facilitating the continuous encapsulation process. After the positive electrode cover 55 is placed, the second transmission platform 4 continues to run. When it reaches the position of the fourth sensor 45, the third cylinder 46 is activated, causing the extension end of the third cylinder 46 to extend, which in turn causes the receiving turntable 57 to press down, compacting the separator 53 and the positive electrode cover 55 onto the sealed hollow cylinder 2, thus completing the automatic encapsulation of the lithium battery cell. This achieves the goal of automatically and continuously encapsulating lithium battery cells.It plays a crucial role in adapting to large-scale lithium battery production, ensuring the consistency of cell packaging, and improving the packaging efficiency and quality of lithium batteries.
