In this way, when the manipulator 20 transfers the aluminum-plastic film and the battery cell to be processed to the pre-folding mechanism 30, the cutting mechanism 50 or the packaging mechanism 40, since the above three mechanisms are arranged along the same straight line, the manipulator 20 does not need to deflect too much during the movement process. Therefore, the battery pack packaging equipment does not need to set corresponding alignment mechanisms on the pre-folding mechanism 30, the packaging mechanism 40 and the cutting mechanism 50, which greatly simplifies the structure of the equipment and thus reduces the volume of the battery pack packaging equipment.

[0058] Optionally, the battery pack packaging equipment also includes a weighing machine, which is installed on the base 10 and located between the vacuum box 60 and the manipulator 20.

[0060] Specifically, after the manipulator 20 grabs the aluminum-plastic film to be packaged, the linear motor 34 of the pre-folding mechanism 30 is controlled first, and the linear motor 34 drives the pre-folding seat 31 to move on the guide rail 32, so that the pre-folding seat 31 is close to the manipulator 20, which is convenient for the manipulator 20 to place the aluminum-plastic film on the pre-folding seat 31; then the manipulator 20 moves to the position for loading the battery cells, grabs the battery cells to be packaged, and finally transfers the battery cells to the pre-folding seat 31; the pre-folding seat 31 folds a part of the aluminum-plastic film, so that the aluminum-plastic film can completely wrap the battery cells and form openings on three sides, which makes it convenient for the packaging mechanism 40 to heat-seal the openings on the opposite sides of the aluminum-plastic film.

[0061] The pre-folding mechanism 30 is provided with a transmission chain 33 . When the pre-folding seat 31 is driven to move by the linear motor 34 , the pre-folding seat 31 can slide on the guide rail 32 more stably through the transmission chain 33 , thereby further improving the stability of the pre-folding seat 31 .

[0062] In one embodiment, please refer to Figures 1 to 5 The pre-folding seat 31 includes an adjusting seat 311 and a placing plate 312. The adjusting seat 311 is slidably connected to the base 10 and is connected to the linear motor 34. The end of the transmission chain 33 away from the guide rail 32 is connected to the adjusting seat 311. The placing plate 312 is movably connected to the side of the adjusting seat 311 facing away from the base 10. The placing plate 312 is used to place the aluminum-plastic film and battery cells to be packaged. The adjusting seat 311 is used to drive the placing plate 312 to move so that the placing plate 312 is close to the position of the robot 20.

[0063] Specifically, the pre-folding seat 31 is divided into an adjustment seat 311 and a placement plate 312. The placement plate 312 is used to place the aluminum-plastic film and battery cells to be packaged. The placement plate 312 is arranged on the adjustment seat 311. The adjustment seat 311 is used to adjust the position of the placement plate 312 on the guide rail 32, that is, the adjustment seat 311 drives the placement plate 312 to approach the manipulator 20, so that the aluminum-plastic film and battery cells on the placement plate 312 are closer to the manipulator 20, which is convenient for the manipulator 20 to operate the aluminum-plastic film and battery cells on the placement plate 312.

[0064] For further information, please refer to Figures 1 to 5The adjustment seat 311 includes a mounting frame 311a, a first drive motor 311b, a lifting cylinder 311c, a lifting plate 311d, a first rotating cylinder 311e and a rotating block 311f.

[0065] In this embodiment, the first driving motor 311b in the adjustment seat 311 drives the screw in the hollow cavity to rotate, and the screw rotates while driving the nut to move, so that the nut drives the moving block to slide along the axial direction of the screw, and then drives the lifting cylinder 311c connected to the moving block to move along the axial direction of the screw, so that the placement plate 312 moves along the front-to-back direction of the adjustment seat 311. The axial direction of the screw is the front-to-back direction of the adjustment seat 311; and the lifting cylinder 311c drives the lifting plate 311d to move in the vertical direction, so that the lifting plate 311d drives the first rotating cylinder 311e to move in the vertical direction, so that the placement plate 312 moves in the vertical direction. The first rotating cylinder 311e drives the rotating block 311f to rotate in the horizontal direction, and the rotating block 311f drives the placement plate 312 to rotate in the horizontal direction, so that the placement plate 312 moves in the horizontal direction. In this way, the adjustment seat 311 can drive the placement plate 312 to move in multiple directions, so that the placement plate 312 can be closer to the robot 20 more easily, so that the robot 20 can place the aluminum-plastic film and the battery core on the placement plate 312.

[0066] In one embodiment, please refer to Figures 1 to 5 The pre-folding seat 31 also includes a second rotating cylinder 311g, a rotating shaft 311h and an assembly plate 311i. The assembly plate 311i is connected to the rotating block 311f. The rotating shaft 311h is rotatably connected to the assembly plate 311i. The second rotating cylinder 311g is arranged on the assembly plate 311i and is connected to the rotating shaft 311h. The placing plate 312 includes a fixed plate 312a and a folding plate 312b hinged to the fixed plate 312a. The fixed plate 312a is arranged on the assembly plate 311i, and the folding plate 312b is connected to one end of the rotating shaft 311h away from the second rotating cylinder 311g.

[0067] Specifically, the second rotating cylinder 311g drives the rotating shaft 311h to rotate, and the rotating shaft 311h drives the folding plate 312b of the placement plate 312 to rotate, so that the folding plate 312b flips relative to the fixed plate 312a, and the folding plate 312b also drives the aluminum-plastic film to bend toward the position of the fixed plate 312a, so that the aluminum-plastic film is folded and wraps the battery cell, thereby realizing the automatic folding of the aluminum-plastic film and speeding up the assembly of the aluminum-plastic film and the battery cell.

[0068] In one embodiment, please refer to Figures 1 to 5 The pre-folding mechanism 30 also includes a detection arm 35 and an in-position sensor 36. The detection arm 35 is connected to the rotating arm of the second rotating cylinder 311g; the in-position sensor 36 is installed on the second rotating cylinder 311g, and the in-position sensor 36 has a detection position. The detection arm 35 movably extends into the detection position so that the in-position sensor 36 detects the movement of the folding plate 312b.

[0069] In this embodiment, when the second rotating cylinder 311g drives the folding plate 312b to rotate to the detection position of the in-place sensor 36, the in-place sensor 36 will output an electrical signal to the main controller of the equipment, so that the main controller can promptly control the manipulator 20 to execute the next step of instructions, thereby speeding up the working efficiency of the battery pack packaging equipment.

[0070] In one embodiment, please refer to Figures 1 to 5 The packaging mechanism 40 includes two hot pressing components 41 . The two hot pressing components 41 are spaced apart from each other on the base 10 and are located on a side of the cutting mechanism 50 away from the pre-folding mechanism 30 .

[0071] In this embodiment, when the robot 20 transfers the folded aluminum-plastic film and the battery cell to the first hot pressing assembly 41, the first hot pressing assembly 41 hot presses and seals the first side opening formed after the folding of the aluminum-plastic film, and the second hot pressing assembly 41 hot presses and seals the second side opening formed after the folding of the aluminum-plastic film. In this way, different positions of the aluminum-plastic film are hot-pressed and sealed by the two hot pressing assemblies 41 respectively, thereby eliminating the step of converting the angle of the aluminum-plastic film, thereby speeding up the processing efficiency of the battery pack packaging equipment.

[0072] It is worth mentioning that after the aluminum-plastic film is folded and hot-pressed twice, an opening is left on one side, and the final opening is used to inject the electrolyte.

[0073] In one embodiment, please refer to Figures 1 to 5Each hot pressing assembly 41 includes a hot pressing frame 411, a lifting drive motor 412, an upper pressing block 413 and a lower pressing block 414, and the hot pressing machine is installed on the base 10; the lifting drive motor 412 is arranged on the hot pressing frame 411; the upper pressing block 413 is slidably connected to the hot pressing frame 411, and is connected to the lifting drive motor 412, so that the lifting drive motor 412 drives the upper pressing block 413 to move up and down; the lower pressing block 414 is arranged on the hot pressing frame 411 and is located below the upper pressing block 413; a hot pressing position is formed between the upper pressing block 413 and the lower pressing block 414, and the hot pressing position is used to place the aluminum-plastic film with a battery cell.

[0074] Specifically, the hot pressing frame 411 is a rectangular structure and is vertically installed on it; the lifting drive motor 412 is installed on the top of the hot pressing frame 411, and the telescopic rod of the lifting drive motor 412 extends into the hot pressing frame 411, and the telescopic rod of the lifting drive motor 412 is connected to a screw rod, and a nut is slidably connected to the screw rod, and the nut is connected to the upper pressing block 413. In this way, the lifting drive motor 412 drives the screw rod to rotate, and the screw rod drives the nut and the upper pressing block 413 to rise and fall along its axial direction, so that the upper pressing block 413 can form hot pressing positions with different spacings with the lower pressing block 414, so that hot pressing positions with different spacings can hot press aluminum-plastic films of different thicknesses, thereby increasing the packaging range of the battery pack packaging equipment.

[0075] In one embodiment, please refer to Figures 1 to 5 The battery pack packaging equipment also includes a vacuum box 60 and a liquid injection mechanism 70. The vacuum box 60 is installed on the base 10.

The vacuum box 60 is used to evacuate the internal air, and the liquid injection mechanism 70 is used to inject electrolyte between the aluminum-plastic film transferred into the vacuum box 60 and the battery cell.

[0076] In this embodiment, the vacuum box 60 is arranged adjacent to the manipulator 20 and the pre-folding mechanism 30. When the vacuum box 60 is powered on, it will absorb the air inside itself, so that the aluminum-plastic film and the battery cell entering the vacuum box 60 are not affected by the air during the process of being injected with electrolyte by the injection mechanism 70, so that the aluminum-plastic film and the battery cell are not easily corroded when in contact with the electrolyte, thereby improving the quality of the battery pack.

[0077] In one embodiment, please refer to Figures 1 to 5 The battery pack packaging equipment also includes a barcode scanning gun 80 and a battery cell feeding mechanism 90 installed on the base 10. The barcode scanning gun 80 is arranged adjacent to the robot 20 and the packaging mechanism 40. The battery cell feeding mechanism 90 is arranged adjacent to the barcode scanning gun 80. The barcode scanning gun 80 is used to scan and identify the battery cells on the battery cell feeding mechanism 90.

[0078] In this embodiment, the cell feeding mechanism 90 is arranged adjacent to the packaging mechanism 40 and the manipulator 20. The cell feeding mechanism 90 can feed multiple cells to a position adjacent to the manipulator 20, so as to facilitate the transfer of the manipulator 20 to other mechanisms for processing. The barcode scanning gun 80 is used to scan and identify the cells on the cell feeding mechanism 90 to avoid installing the cells on non-corresponding aluminum-plastic films, thereby ensuring the installation accuracy of the battery pack.

[0079] The specific production process of the battery pack packaging equipment is as follows: the robot 20 first loads the aluminum-plastic film onto the pre-folding mechanism 30, and then controls the barcode scanning gun 80 to scan and identify the battery cell on the battery cell feeding mechanism 90. The robot 20 then transfers the scanned battery cell to the pre-folding mechanism 30 where the aluminum-plastic film is placed. At this time, the battery cell is placed on the aluminum-plastic film; then the pre-folding mechanism 30 flips the aluminum-plastic film so that the aluminum-plastic film is folded and wraps the battery cell; then the robot 20 transfers the folded aluminum-plastic film and the battery cell to the cutting machine. The cutting mechanism 50 cuts off the redundant position of the aluminum-plastic film, and the aluminum-plastic film now forms openings on three sides; the manipulator 20 then transfers the aluminum-plastic film with openings on three sides and the battery cell to the packaging mechanism 40, and uses the two hot pressing components 41 of the packaging mechanism 40 to heat-press and seal the openings on both sides of the aluminum-plastic film in turn, and the aluminum-plastic film now has only one side opening; finally, the manipulator 20 transfers the aluminum-plastic film to the vacuum box 60, and the liquid injection mechanism 70 injects the electrolyte into the aluminum-plastic film to complete the processing of the battery pack.
