[0067] The working principle of this utility model:

[0068] In this embodiment, as Figure 3As shown, a feeding rack 7 is provided, and an X-axis guide rail 71 is horizontally arranged on the feeding rack 7. The moving ends of the first feeding X-axis moving unit 2 and the second feeding X-axis moving unit 5 can both move horizontally along the X-axis guide rail 71. In this embodiment, a positive electrode feeding box and a negative electrode feeding box can be provided, respectively located below the first feeding X-axis moving unit 2 and the second feeding X-axis moving unit 5. The moving end of the first feeding Z-axis moving unit 3 causes the first feeding gripper 1 to move up and down to transport the adsorbed positive electrode sheet. Similarly, the moving end of the second feeding Z-axis moving unit 6 causes the second feeding gripper 4 to move up and down to transport the adsorbed negative electrode sheet. The stacking platform 37 is located below the middle of the feeding rack 7, and the first feeding gripper 1 and the second feeding gripper 4 do not interfere with the stacking mechanism and the diaphragm unwinding mechanism during movement. The first feeding gripper 1 moves horizontally along the first feeding X-axis moving unit 2 and the first feeding Z-axis moving unit 5. Unit 3 adjusts its position to feed positive electrode sheets onto the stacking platform 37. Similarly, the second feeding gripper 4 adjusts its position via the second feeding X-axis moving unit 5 and the second feeding Z-axis moving unit 6 to feed negative electrode sheets onto the stacking platform 37. Positive or negative electrode sheets are fed according to a specific sequence. The diaphragm unwinding mechanism provides diaphragm material via the winding roller 8. After the tension of the diaphragm material is adjusted by the tension roller 10, it reaches the film pulling roller 9. In this embodiment, the stacking platform 37 has multiple feeding rollers above it (not shown in the attached figures). Depending on actual needs, the diaphragm material passes through multiple feeding rollers to the film pulling roller 9, or is conveyed from the film pulling roller 9 to multiple feeding rollers to stack and wrap the negative or positive electrode sheets in a Z-shape or alternating pattern. In addition, positive or negative electrode sheets can be continuously wrapped, which can realize different stacking methods and simultaneously meet the requirements of different sizes of positive and negative electrode sheets, thereby forming cells of different sizes or types.

[0069] The stacking Y-axis moving mechanism 39 can drive the stacking platform 37, the stacking pressure knife 38, the pressure knife X-axis moving unit 40, and the pressure knife Z-axis moving unit 41 to move together in the Y-axis direction. Similarly, the stacking Z-axis moving mechanism 43 can drive the stacking platform 37, the stacking pressure knife 38, the pressure knife X-axis moving unit 40, and the pressure knife Z-axis moving unit 41 to move together in the Z-axis direction. The pressure knife X-axis moving unit 40 is disposed on the side wall of the stacking platform 37, and two pressure knife X-axis moving units are disposed on the pressure knife X-axis moving unit 40. On the mobile end, each pressing knife X-axis moving end is equipped with a pressing knife Z-axis moving unit 41. The lifting end of each pressing knife Z-axis moving unit 41 is connected to a stacking pressing knife 38. Therefore, each stacking pressing knife 38 can be lifted and lowered independently to press the positive electrode sheet, negative electrode sheet, or separator. The pressing knife X-axis moving end on the pressing knife X-axis moving unit 40 can drive the stacking pressing knife 38 to move in the X-axis direction. In this embodiment, the Z-axis direction is a vertical lifting direction, and the X-axis direction and Y-axis direction are horizontally perpendicular to each other. Please refer to the attached figure. Figure 1The arrows indicate that the X-axis direction includes the direction in which the arrow points and the opposite direction, and the Y-axis direction includes the direction in which the arrow points and the opposite direction. In this embodiment, the film-pulling roller 9 may also be provided with a structure that drives its movement in the Y-axis direction, which is not shown in the figures. The stacking pressure knife 38 on the stacking platform 37 drives the diaphragm material to move in the Y-axis direction and can pass between the support plate 11 and the pressure plate 12. The pressure lifting unit 13 drives the pressure plate 12 to press the diaphragm material. Both the first laser cutter and the second laser cutter can be lasers. The lasers can cut the diaphragm material below. The first laser cutter and the second laser cutter are both located outside the multiple feeding rollers to avoid interference or cutting the diaphragm material wrapped around the feeding rollers. See attached figure. Figure 4 In the middle, the first laser-cut part is located on the left side of the feeding roller, and the second laser-cut part is located between the feeding roller and the winding roller 8.

[0070] After stacking, the battery cells are transferred to the adhesive application platform 14 via the first transport mechanism 30, where they are pressed by the adhesive application pressure plate 16. The adhesive application rotation drive unit 15 controls the adhesive application platform 14 to rotate, causing all sides of the battery cells to face the adhesive application output mechanism. The side adhesive roll unit 17 outputs side adhesive material to the guide output unit 18, and the output three-axis movement mechanism 35 can drive the adhesive application frame 20 to move in the X, Y, and Z axes, thereby moving the side adhesive roll unit 17, the guide output unit 18, and the cutter unit 19 together to apply adhesive to the sides of the battery cells. In addition, the side adhesive cutter has a telescopic structure and a flipping structure, which are not shown in this embodiment, but can be driven by telescopic structures such as electric cylinders or air cylinders to cut the adhesive material.

[0071] After the adhesive is applied, the battery cell is moved to the hot pressing platform 21 by the second conveying mechanism 31. The lower hot pressing mechanism 22, which can be raised and lowered, performs hot pressing on the battery cell of the hot pressing platform 21. The first heating element 212 can cause the hot pressing platform 21 to heat up (the first pad 211 heats up), and the second heating element 221 can cause the lower hot pressing mechanism 22 to heat up (that is, the second pad 222 heats up).

[0072] Along the X-axis extension line of the second conveying mechanism 31, the second conveying mechanism 31 transfers the hot-pressed battery cells to the unloading box (not shown in the figure) of the unloading mechanism or the buffer plate 33 of the unloading buffer mechanism, or docks them through the unloading claws 23, and finally outputs them through the unloading conveyor belt mechanism 36 to complete the unloading of the battery cells.

[0073] This utility model includes a diaphragm unwinding mechanism and a stacking mechanism. The stacking mechanism is equipped with at least two sets of stacking pressure knives 38 and a stacking platform 37 to press and move the electrode sheets and diaphragm together, which can meet different stacking methods of battery cells. It also has adhesive application and hot pressing processes, with a high degree of automation, and can complete the hot composite stacking process with high efficiency throughout, meeting the needs of battery cell stacking of different sizes. The bottom of the adhesive application assembly can be equipped with an X-axis moving structure, which can be used to transport the adhesive-applied battery cells to the leftmost position of the second transport mechanism 31. Figure 1 (As shown).

[0074] In addition, the stacked cells are transported to the adhesive application platform 14. The adhesive application component can apply adhesive to the side of the stacked cells, and the hot pressing component can hot press the glued cells. Finally, the cells are output through the unloading conveyor belt mechanism 36, realizing fully automated feeding, stacking, adhesive application, hot pressing, and unloading, reducing manual input and increasing work efficiency.

It should be noted that those skilled in the art can make various improvements and modifications without departing from the principle of this utility model, and these improvements and modifications are also considered within the scope of protection of this utility model.
