[0022] In the above, the battery cells that have been stacked are transported to the battery cell positioning and arranging component 5, and are neatly arranged through the battery cell positioning and arranging component 5. After completion, the electric guide rail 33 in the battery cell automatic feeding module 3 is started, and the mounting plate 35 is moved to move the battery cell positioning and arranging component 5 to the position of the battery cell positioning and conveying component 4, and the battery cell positioning and conveying component 4 is moved to the hot pressing component 2. Then the mounting plate 35 returns to reset the battery cell positioning and conveying component 4 and the battery cell positioning and arranging component 5. At this time, the battery cells arranged by the battery cell positioning and arranging component 5 are moved into the battery cell positioning and conveying component 4. When running again, the battery cells can be moved to the hot pressing component 2 through the battery cell positioning and conveying component 4 to complete the hot pressing, and the battery cells are returned and conveyed through the pressed battery cell return component 6.

[0023] In a preferred embodiment, please refer again to Figure 3 The hot pressing assembly 2 includes four lifting guide rods 21, a top plate 22 is fixed on the top of the lifting guide rods 21, a hydraulic cylinder 23 is fixed on the top of the top plate 22, a lifting and pressing platform 24 is fixed at the output end of the hydraulic cylinder 23 and located below the top plate 22, the lifting and pressing platform 24 is slidably connected to the lifting guide rods 21, a fixed pressing platform 25 is installed on the upper surface of the device base 1 and at a position corresponding to the lifting and pressing platform 24, a heat spreader is installed on the lower surface of the lifting and pressing platform 24 and the upper surface of the fixed pressing platform 25, a heater is arranged inside the lifting and pressing platform 24 and the fixed pressing platform 25, and the heater is connected to the heat spreader.

[0024] In this embodiment, when the battery cell moves to the hot pressing assembly 2, the hydraulic cylinder 23 is started to push the lifting and pressing platform 24 to move downward along the lifting guide rod 21 until it contacts the top of the battery cell, and continues to apply pressure to the battery cell. At the same time, the heater starts to work and transfers heat to the battery cell evenly through the heat spreader to reach the required temperature. Under the action of the heater, the battery cell is pressed and maintained for a period of time to ensure that the stacked sheets in the battery cell are tightly combined. After the pressing is completed, the hydraulic cylinder 23 controls the lifting and pressing platform 24 to rise to complete the hot pressing.

[0025] Secondly, please also refer to Figure 3 and Figure 4 The automatic cell feeding module 3 also includes a first fixed plate 31 and a second fixed plate 32. The first fixed plate 31 and the second fixed plate 32 are both fixed inside the device box frame 11. The first fixed plate 31 is fixed to the other end inside the device box frame 11, and the second fixed plate 32 is fixed to one side of the hot pressing assembly 2. The electric guide rail 33 is fixed between the first fixed plate 31 and the second fixed plate 32. An electric slider 34 is installed at the bottom of the electric guide rail 33, and the mounting plate 35 is fixed to the bottom of the electric slider 34.

[0026] In the above, the first fixed plate 31 and the second fixed plate 32 of the automatic battery cell feeding module 3 provide a stable support structure for the electric guide rail 33 to ensure that it is fixed inside the device box frame 11. When the electric guide rail 33 is started, it can drive the electric slider 34 to move along the direction of the electric guide rail 33, and at the same time drive the fixed mounting plate 35 below to move together. As the mounting plate 35 moves, it can drive the battery cell positioning and conveying assembly 4 and the battery cell positioning and arranging assembly 5 installed at both ends thereof to move together, and move the battery cell positioning and arranging assembly 5 to the position of the battery cell positioning and conveying assembly 4, so that the arranged battery cells are in the area to be conveyed, and the battery cells originally located in the battery cell positioning and conveying assembly 4 are pushed to the hot pressing assembly 2 to complete hot pressing. During the hot pressing process, the battery cells can continue to be conveyed to the battery cell positioning and arranging assembly 5 to complete the arrangement, which makes the hot pressing process smoother, and there is no need to convey multiple battery cells individually when hot pressing at the same time, and the hot pressing efficiency is higher.

[0027] Secondly, please refer to Figure 5 The battery cell positioning and conveying assembly 4 includes a first outer ring limiting plate 41, a first inner ring positioning block 42 is arranged in the middle of the inner side of the first outer ring limiting plate 41, a plurality of positioning plates 43 are arranged between the first outer ring limiting plate 41 and the first inner ring positioning block 42, a plurality of battery cell positioning areas 44 are formed between the plurality of positioning plates 43, a first electric push rod 36 is fixed to one end of the mounting plate 35, an output end of the first electric push rod 36 is fixed to the first inner ring positioning block 42, a finished product push plate 45 is fixed to the outer side of the first outer ring limiting plate 41, the finished product push plate 45 is located on the side close to the hot pressing assembly 2, and the shape of the finished product push plate 45 is arc-shaped.

[0028] As described above, the arranged battery cells will be located in each battery cell positioning area 44. When the mounting plate 35 pushes the battery cell positioning and conveying assembly 4 to move as a whole, the battery cells located in the battery cell positioning area 44 will move along, thereby enabling the battery cells to enter the hot pressing assembly 2 for hot pressing. After the battery cells enter the hot pressing assembly 2, the battery cell positioning and conveying assembly 4 is lifted as a whole by the first electric push rod 36, and the lifting height is made higher than the thickness of the battery cells, so that the battery cells can remain in the hot pressing assembly 2 when the battery cell positioning and conveying assembly 4 is reset.

[0029] Furthermore, the finished product push plate 45 installed on the outside of the first outer ring limit plate 41 can move together with the battery cell positioning and conveying assembly 4. When the battery cell positioning and conveying assembly 4 conveys the battery cell to the hot pressing assembly 2, the finished product push plate 45 can push the battery cell that has been pressed to the pressed battery cell stripping assembly 6 to complete the stripping of the battery cell.

[0030] In a preferred embodiment, please refer again to Figure 6 The battery cell positioning and arrangement component 5 includes a second outer ring limiting plate 51, a second inner ring rotating block 52 is arranged in the middle of the inner side of the second outer ring limiting plate 51, a plurality of rotating push plates 53 are fixed to the outer side of the second inner ring rotating block 52, a feed port is provided on the outer side of the second outer ring limiting plate 51 and located at the battery cell conveyor belt, and the size of the feed port is the same as the interval between the two rotating push plates 53, a third fixed plate 54 is fixed to the top of the second outer ring limiting plate 51, a motor protective shell 56 is fixed to the top of the third fixed plate 54, a first motor 55 is fixed inside the motor protective shell 56, and the output end of the first motor 55 is fixed to the second inner ring rotating block 52, a second electric push rod 37 is fixed to the other end of the mounting plate 35, and the output end of the second electric push rod 37 is fixed to the top of the motor protective shell 56.

[0031] In this embodiment, the stacked battery cells enter the second outer ring limit plate 51 through the feed port and are located between the two rotating push plates 53. After the battery cells enter between the two rotating push plates 53, the first motor 55 drives the second inner ring rotating block 52 and the rotating push plates 53 to rotate together, so that the battery cells are pushed to the inside of the second outer ring limit plate 51 and the two new rotating push plates 53 are located at the feed port. Repeating the above process can arrange the battery cells neatly in the second outer ring limit plate 51.

[0032] Furthermore, after the arranged battery cells are conveyed to the next step, the second electric push rod 37 can drive the entire battery cell positioning and arranging assembly 5 to rise so that the lifting height is higher than the thickness of the battery cells. After resetting, the arranged battery cells can remain in the position of the original battery cell positioning and conveying assembly 4, and after the battery cell positioning and conveying assembly 4 is reset, each arranged battery cell is in the battery cell positioning area 44, waiting for the next conveyance.

[0033] Next, please refer to Figure 7 The pressed cell stripping assembly 6 includes an extension bracket 61, a support leg 62 is fixed to the bottom of one end of the extension bracket 61, a first conveyor belt 65 is obliquely installed between the extension bracket 61 and the support leg 62, a second motor 66 is fixed to one side of the bottom of the support leg 62, and the output end of the second motor 66 is connected to the transmission shaft of the first conveyor belt 65, a second conveyor belt 67 is installed at the end angle of one end of the device base 1, a third motor 68 is fixed to one side of the device base 1, and the output end of the third motor 68 is fixed to the transmission shaft of the second conveyor belt 67, a side baffle 63 is fixed at the angle between the extension bracket 61 and the support leg 62, and the side baffle 63 is located on both sides of the first conveyor belt 65, and a U-shaped top baffle 64 is fixed to the top of the extension bracket 61.

[0034] In the above, by starting the second motor 66 and the third motor 68, the first conveyor belt 65 and the second conveyor belt 67 can be put into operation. When the battery cell after the pressing is completed is pushed, it will enter the second conveyor belt 67, and enter the first conveyor belt 65 after being conveyed to complete the material return. At the same time, the side baffles 63 arranged on both sides of the first conveyor belt 65 and the U-shaped top baffle 64 on the top of the extension bracket 61 can prevent the battery cell from leaving the original conveying area during the material return process.

[0035] The working principle of the present invention is as follows: the battery cell positioning and arranging component 5 is set up to arrange the single transported battery cells as a whole and limit the positions of the arranged battery cells. When the battery cell positioning and conveying component 4 and the battery cell positioning and arranging component 5 are controlled to move simultaneously, the battery cell positioning and arranging component 5 can move the arranged battery cells to the area of ​​the original battery cell positioning and conveying component 4, and after the battery cell positioning and conveying component 4 and the battery cell positioning and arranging component 5 are reset, the battery cells are placed in the battery cell positioning area 44 of the battery cell positioning and conveying component 4. In the next transportation, the battery cells located in the battery cell positioning area 44 can be transported to the hot pressing component 2 to complete the hot pressing. This continuous loading method that can load multiple battery cells at the same time can reduce the time for the battery cells to enter the hot pressing component 2 when the device is hot pressing multiple battery cells at the same time, thereby increasing the hot pressing efficiency of the device.

[0036] The above is only a preferred embodiment of the present invention. It should be noted that, for those skilled in the art, several improvements and modifications can be made without departing from the principles of the present invention, and these improvements and modifications should also be considered as the protection scope of the present invention.
