Battery modules play a crucial role in fields such as new energy vehicles and energy storage systems. Cell stacking is a critical step in battery module production. Through proper stacking, the cells are arranged according to design requirements, thereby achieving higher energy density and a more efficient structure within a limited space.
[0003] Currently, the stacking of battery cells mainly involves manually picking up the cells and arranging them one by one. After picking up one cell, an insulating pad is attached before stacking the next cell. Due to the weight of the battery cells, this method is labor-intensive and inefficient. Therefore, those skilled in the art have provided a battery cell pre-stacking mechanism to solve the problems mentioned in the background art. Utility Model Content

[0028] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.
[0029] Please see the appendix Figures 1 to 4 As shown, a pre-stacking mechanism for battery cells in this embodiment of the present invention includes a base plate 1. A moving mechanism 2 is provided at the middle of the upper surface of the base plate 1. A transfer conveyor 3 is connected above the moving mechanism 2. The moving mechanism 2 drives the transfer conveyor 3 to move, switching between the feeding conveyor belt 6 and the manual operation area.
[0030] The transfer conveyor 3 includes a movable base 31. A straight block 32 and an L-shaped block 34 are fixedly connected to both sides of the upper end face of the movable base 31. A conveyor belt 33 is arranged between the straight block 32 and the L-shaped block 34. The conveyor belt 33 is used to drive the movement of the battery cells. The L-shaped block 34 can guide the incoming battery cells. At the same time, when the transfer conveyor 3 moves forward, its rear protruding edge can prevent the battery cells from tipping over. The upper surface of the straight block 32 is at the same height as the upper surface of the conveyor belt 33, which facilitates the removal of the stacked battery cells.
[0031] A frame 4 is fixedly connected to the upper end of the base plate 1 above the transfer conveyor seat 3, and a blocking component 5 is fixedly connected to the upper end of the frame 4.
[0032] The blocking assembly 5 includes multiple vertical cylinders 51. A connecting frame 52 is fixedly connected to the extended end of each vertical cylinder 51. A movable baffle 53 is fixedly connected to the lower end of the connecting frame 52. A fixed baffle 56 is fixedly connected to the lower side of one side of the frame 4. Pressure sensing pads 54 are fixedly connected to the lower side of both the movable baffle 53 and the fixed baffle 56. Each vertical cylinder 51 is independently set and can drive the movable baffle 53 to descend sequentially from the fixed baffle 56 to block the battery cells. In use, the battery cell that first enters the transfer conveyor 3 will be blocked by the fixed baffle 56 and trigger the pressure sensing pad 54 on it. Then, the vertical cylinder 51 adjacent to the fixed baffle 56 extends and drives the movable baffle 53 connected to it to descend, thereby blocking the next battery cell. Subsequent battery cells enter sequentially. Correspondingly, after the pressure sensing pad 54 of the movable baffle 53 is triggered, the next movable baffle 53 also descends, so that the battery cells on the transfer conveyor 3 can be separated sequentially, thereby completing the pre-stacking of the battery cells.
[0033] Fixed seats 7 are fixedly connected to both sides of the upper end face of the base plate 1 away from the transfer and conveying seat 3. A fixed block 8 is fixedly connected to the inner side of one fixed seat 7, and a compression cylinder 9 is fixedly connected to the upper end of the other fixed seat 7. A compression block 10 is fixedly connected to the extended end of the compression cylinder 9. The compression block 10 and the fixed block 8 are in corresponding positions and have the same height. The compression cylinder 9 drives the compression block 10 to move, thereby compressing and shaping the battery cell.
[0034] The moving mechanism 2 includes a servo motor 23 and a lead screw 22 rotatably connected to the middle of the upper end face of the base plate 1. The output end of the servo motor 23 is fixedly connected to the lead screw 22. The lower end of the moving seat 31 is sleeved with the lead screw 22. Both sides of the lead screw 22 are provided with slide rails 21 fixedly connected to the base plate 1. Both sides of the lower end face of the moving seat 31 are fixedly connected with sliding sleeves 35. The sliding sleeves 35 are slidably connected to the slide rails 21. When the moving mechanism 2 is in use, the servo motor 23 drives the lead screw 22 to rotate, thereby driving the moving seat 31 to move.
[0035] Each of the multiple movable baffles 53 is equipped with an anti-pressure component 55 at its lower end. The anti-pressure component 55 includes a pressure sensor 553 and two spring rods 551 fixedly connected to the lower end of the movable baffle 53. The lower ends of the two spring rods 551 are fixedly connected to contact plates 552. The pressure sensor 553 is fixedly connected to the middle of the lower end of the movable baffle 53. A gap is left between the detection end of the pressure sensor 553 and the contact plate 552. The anti-pressure component 55 is used to prevent the movable baffle 53 from squeezing the battery cell when it is lowered. Specifically, if there is a battery cell below when the movable baffle 53 is lowered, the contact plate 552 will first contact the battery cell and retract, then trigger the pressure sensor 553. After that, the corresponding vertical cylinder 51 stops moving and retracts, and the transfer conveyor 3 and the feeding conveyor 6 stop, thereby preventing the battery cell from being squeezed and damaged.
[0036] A feeding conveyor belt 6 is fixedly connected to the upper end face of the base plate 1 away from the fixed baffle 56, and the feeding conveyor belt 6 is aligned with the transfer conveyor seat 3.
[0037] Working principle: During use, the transfer conveyor 3 is aligned with the feeding conveyor belt 6. The feeding conveyor belt 6 sequentially feeds the battery cells to the transfer conveyor 3. The battery cells entering the transfer conveyor 3 first are blocked by the fixed baffle 56, which triggers the pressure sensing pad 54 on it. Then, the vertical cylinder 51 adjacent to the fixed baffle 56 extends, driving the movable baffle 53 connected to it to descend, thereby blocking the next battery cell. Subsequent battery cells enter in sequence, and the movable baffle 53 also descends accordingly, so that the battery cells on the transfer conveyor 3 can be separated in sequence, thus completing the pre-stacking of the battery cells. After the last battery cell enters, the blocking component 5 resets, the feeding conveyor belt 6 and the transfer conveyor 3 stop, and the moving mechanism 2 drives the transfer conveyor 3 to the front end of the base plate 1. The subsequent alignment and the mounting of the end plates and insulation plates are performed manually. Since there are gaps between each battery cell, it is more convenient to mount the insulation plates. After the mounting is completed, the extrusion cylinder 9 drives the extrusion block 10 to extrude and shape the battery cells.
[0038] The above description provides a detailed account of one embodiment of the present invention. However, this description is merely a preferred embodiment and should not be construed as limiting the scope of the present invention. All equivalent variations and improvements made within the scope of the claims of the present invention should still fall within the patent coverage of the present invention.
