It should be understood that these embodiments are provided so that the disclosure of this application is thorough and complete, and that the concept of these exemplary embodiments is fully conveyed to those skilled in the art.

[0203] Reference Figure 1-14 This application provides a cell stacking system. This cell stacking system is used in blade batteries and enables high-speed, high-precision stacking.

[0204] like Figure 1 As shown, the cell stacking system includes a traverse assembly 100, a restraint assembly 300 disposed above the traverse assembly 100, a detection assembly 400, and a stacking assembly 500, as well as a cell transport carrier 200 movably disposed on the traverse assembly 100. Optionally, the cell stacking system further includes a first stepping mechanism 600, a second stepping mechanism 700, and a transfer mechanism.

[0205] Optionally, the stacking assembly 500 is located in the middle of the transverse assembly 100. The working position is located below the stacking assembly 500.

[0206] Optionally, two restraint assemblies 300 are located at both ends of the stacked assembly 500. The two restraint assemblies 300 are symmetrically arranged and spaced apart along the X direction. The two restraint assemblies 300 are located on both sides of the stacked assembly 500. The area below the restraint assemblies 300 is a ready position.

[0207] Optionally, the two detection assemblies 400 are located at both ends of the stacked assembly 500. The two detection assemblies 400 are symmetrically arranged and spaced apart along the X direction. The two detection assemblies 400 are located on both sides of the stacked assembly 500.

[0208] Optionally, the two sets of cell transport carriers 200 move alternately at the ends and the middle of the transverse assembly 100. That is, the two sets of cell transport carriers 200 move alternately from below the restraint assemblies 300 at both ends to below the stacking assembly 500 in the middle.

[0209] like Figure 2As shown, the transverse assembly 100 includes a full positioning mechanism 101, a long guide rail 102, and a conveying mechanism 103. The long guide rail 102 extends along the X direction. The full positioning mechanism 101 is movably disposed on the long guide rail 102. Optionally, the full positioning mechanism 101 is mounted to the long guide rail 102 via the conveying mechanism 103, and the cell conveying carrier 200 can move with the movement of the conveying mechanism 103.

[0210] As shown in the figure, the cell stacking system of this application is provided with four sets of full positioning mechanisms 101. Two sets of full positioning mechanisms 101 are arranged at intervals along the Y direction. Correspondingly, two sets of long guide rails 102 are arranged at intervals along the Y direction. Optionally, each set of full positioning mechanisms 101 is installed to a set of conveying mechanisms 103, and a set of conveying mechanisms 103 corresponds to a set of long guide rails 102. The two sets of full positioning mechanisms 101 can act on opposite sides of the cell in the Y direction, that is, the two sets of full positioning mechanisms 101 constitute a set of full positioning mechanisms 101. Optionally, a set of full positioning mechanisms 101 corresponds to a cell conveying carrier 200. In the illustrated embodiment, two sets of full positioning mechanisms 101 and two cell conveying carriers 200 are provided. Optionally, a cell conveying carrier 200 is installed above the two sets of conveying mechanisms 103 so that a set of full positioning mechanisms 101 can move stably and synchronously with the two sets of conveying mechanisms 103.

[0211] The following explanation uses a set of full positioning mechanism 101 as an example.

[0212] The cell transport carrier 200 is used to carry the cell. Optionally, the cell transport carrier 200 is equipped with a pallet.

[0213] like Figures 3 to 7 As shown, the full positioning mechanism 101 includes positioning clamping plates 101-1 for holding the battery cell. The positioning clamping plates 101-1 clamp the battery cell carried on the battery cell transport carrier 200. Two positioning clamping plates 101-1 are spaced apart along the Y direction, thereby acting on opposite sides of the battery cell in the Y direction to achieve lateral limiting of the battery cell, thus achieving clamping of the battery cell. At least a portion of the positioning clamping plates 101-1 is located above the battery cell transport carrier 200. The battery cell transport carrier 200 limits the bottom of the battery cell. The positioning clamping plates 101-1 and the battery cell transport carrier 200 define a space for accommodating the battery cell.

[0214] like Figure 4 As shown, the positioning plate 101-1 has slots 101-2 extending along the Z direction, and multiple slots 101-2 are spaced apart along the X direction. The slots 101-2 enable precise positioning of the battery cell in the X direction. Optionally, the slots 101-2 are equally spaced. The slots 101-2 guide and position the battery cells to be stacked on the battery cell transport carrier 200.

[0215] Optionally, the positioning plate 101-1 can move relative to the mounting plate 103-1 in the X and / or Y directions. Specific embodiments of the positioning plate 101-1 moving in the X and Y directions are described below.

[0216] like Figures 3 to 4 As shown, the full positioning mechanism 101 includes a first clamping plate guide rail 101-3 and a second clamping plate guide rail 101-5. The positioning clamping plate 101-1 is movable relative to the first clamping plate guide rail 101-3 in the X direction. The positioning clamping plate 101-1 is movable relative to the second clamping plate guide rail 101-5 in the Y direction.

[0217] The first pallet guide rail 101-3 extends along the X direction, and the positioning pallet 101-1 is movably disposed on the first pallet guide rail 101-3.

[0218] Optionally, the system also includes a mover mounting plate 101-6. The mover mounting plate 101-6 is slidably connected to the first pallet guide rail 101-3, and the positioning pallet 101-1 is mounted to the first pallet guide rail 101-3 via the mover mounting plate 101-6. A first pallet drive member 101-4 is connected to the mover mounting plate 101-6. The first pallet drive member 101-4 drives the mover mounting plate 101-6 to slide on the first pallet guide rail 101-3, causing the positioning pallet 101-1 to move relative to the first pallet guide rail 101-3.

[0219] Optionally, the first pallet drive 101-4 is a linear motor. Optionally, the mover mounting plate 101-6 is mounted to the mover of the linear motor 101-4, and the mover is mounted to the slide rail of the linear motor 101-4. The first pallet guide rail 101-3 and the slide rail of the linear motor 101-4 are spaced apart and arranged side by side, and the mover mounting plate 101-6 is mounted on the side-by-side first pallet guide rail 101-3 and the slide rail of the linear motor 101-4. The position of the positioning pallet 101-1 can be adjusted by adjusting the relative position of the mover on the slide rail.

[0220] Multiple positioning plates 101-1 are arranged side-by-side along the X-direction, with adjacent positioning plates 101-1 abutting each other, thus causing the slots 101-2 to be arrayed along the X-direction at preset intervals. Each positioning plate 101-1 corresponds to a mover mounting plate 101-6, allowing individual adjustment of each positioning plate 101-1. The mover mounting plates 101-6 are respectively mounted on the four movers of the first plate drive component 101-4 and the four sliders of the first plate guide rail 101-3, allowing adjustment of the position of the positioning plates 101-1 and their distance from each other. Fasteners 101-10 can be locked after the movers of the linear motor 101-4 are adjusted into position, ensuring the fixed position of the positioning plates 101-1. Optionally, fasteners 101-10 are clamps. Clamps 101-10 can be locked after the mover mounting plates 101-6 are adjusted into position, thus ensuring the fixed position of the positioning plates 101-1.

[0221] The slots 101-2 of the positioning plate 101-1, which are set opposite to each other along the Y direction, are set opposite to each other so that the opposite slots 101-2 can hold the same battery cell, ensuring the spacing and accuracy of the battery cell stacking.

[0222] Optionally, the positioning plate 101-1 is mounted to the mover mounting plate 101-6 via the quick-change strip 101-7. Specifically, the positioning plate 101-1 is mounted on the quick-change strip 101-7, the quick-change strip 101-7 is mounted on the quick-change strip mounting plate 101-8, and the quick-change strip mounting plate 101-8 is mounted to the mover mounting plate 101-6. A rotary locking device 101-9 is installed between the quick-change strip 101-7 and the quick-change strip mounting plate 101-8, allowing for quick replacement of the quick-change strip 101-7. This is suitable for stacking different types of battery cells.

[0223] like Figure 4 As shown, the first pallet guide rail 101-3 is mounted on the pallet guide rail mounting base 101-11, and the pallet guide rail mounting base 101-11 is also equipped with a first adjusting block 101-12 for adjusting the installation position of the first pallet guide rail 101-3.

[0224] The second pallet guide rail 101-5 extends along the Y direction, and the positioning pallet 101-1 is movably mounted on the second pallet guide rail 101-5.

[0225] The second pallet guide rail 101-5 is mounted on the support 103-15 of the conveying mechanism 103. The positioning pallet 101-1 is mounted to the second pallet guide rail 101-5 via the second pallet guide rail slider 101-15. Further, the pallet guide rail mounting seat 101-11 is mounted on the second pallet guide rail slider 101-15. Therefore, the positioning pallet 101-1 can move relative to the second pallet guide rail slider 101-15 in the X direction under the drive of the first pallet drive member 101-4, and simultaneously can move relative to the second pallet guide rail 101-5 in the Y direction under the drive of the second pallet guide rail slider 101-15.

[0226] The second pallet guide slider 101-15 moves along the second pallet guide rail 101-5 under the drive of the second pallet drive component. Optionally, the second pallet drive component includes a first linear module 101-13 and a module pad 101-14. The first linear module 101-13 can drive the module pad 101-14 to move in the Y direction. The pallet guide rail mounting seat 101-11 is mounted on the drive module pad 101-14. That is, the pallet guide rail mounting seat 101-11 is mounted on the second pallet guide slider 101-15 and the drive module pad 101-14. The pallet guide rail mounting seat 101-11 moves in the Y direction under the drive of the drive module pad 101-14, thereby causing the second pallet guide slider 101-15 to slide relative to the second pallet guide rail 101-5.

[0227] The second pallet drive component and the second pallet guide rail 101-5 are spaced apart. Optionally, two sets of second pallet guide rails 101-5 are provided, located on opposite sides of the second pallet drive component along the X direction. Optionally, the second pallet guide rails are mounted on the support 103-15 of the conveying mechanism 103. Optionally, the support 103-15 is provided with a limit block 103-12, located on the side of the support 103-15 away from the full positioning mechanism 101. The limit block 103-12 can limit the extreme position of the full positioning mechanism 101's movement along the Y direction.

[0228] like Figure 5 As shown, the conveying mechanism 103 includes a mounting plate 103-1 and a transverse drive 103-2. The mounting plate 103-1 is movably connected to the long guide rail 102. Optionally, the transverse drive 103-2 is configured as a servo motor, with a drive roller connected to the motor shaft. Transmission is achieved through the engagement of the roller and rack 103-13. The cell conveying carrier 200 and the full positioning mechanism 101 are mounted above the mounting plate 103-1. The transverse drive 103-2 drives the mounting plate 103-1 to move along the long guide rail 102. The full positioning mechanism 101 moves a predetermined distance along the X direction with the mounting plate 103-1 at predetermined time intervals.

[0229] The mounting plate 103-1 is provided with a first support portion 103-3, which supports the cell transport carrier 200. Understandably, the cell transport carrier 200 can be placed above the first support portion 103-3. The mounting plate 103-1 is also provided with a rolling element 103-4. The rolling element 103-4 is spaced apart from the first support portion 103-3. Optionally, the rolling element 103-4 is a pneumatic roller. The rolling element 103-4 is mounted to the mounting plate 103-1 via a roller mounting plate 103-5. The rolling element 103-4 can move along the Z direction to be higher, lower, or flush with the first support portion 103-3. When the rolling element 103-4 is higher than the first support portion 103-3, the cell transport carrier 200 can detach from the first support portion 103-3. The rolling element 103-4 can be rotatably connected to the cell transport carrier 200 in order to reduce the resistance when the cell transport carrier 200 is positioned.

[0230] like Figure 5 As shown, the conveying mechanism 103 also includes a positioning element. The positioning element enables precise positioning of the battery cell conveying carrier 200 along the Y direction and precise positioning along the X direction.

[0231] The positioning component includes a first positioning component 103-6. The first positioning component 103-6 is disposed on the side of the cell transport carrier 200. The first positioning component 103-6 is driven to move along the Y direction by a first positioning component cylinder 103-7 to achieve positioning of the cell transport carrier 200 along the Y direction. Two sets of first positioning components 103-6 are respectively located on both sides of the cell transport carrier 200. Optionally, a V-block 103-8 is provided on the side of the first positioning component 103-6 closest to the cell transport carrier 200, with the opening of the V-block 103-8 facing the cell transport carrier 200. The two-point contact between the V-block 103-8 and the cell transport carrier 200 facilitates the positioning of the cell transport carrier 200 and reduces errors.

[0232] The positioning components include a second positioning component 103-9. A third positioning component 201 is disposed below the cell conveying carrier 200. The third positioning component 201 can be connected to the second positioning component 103-9 in a compatible manner. The second positioning component 103-9 can move along the Z direction under the drive of the second positioning component cylinder 103-10, thereby allowing the second positioning component 103-9 to selectively dock with the third positioning component 201. Optionally, the second positioning component 103-9 is a positioning pin sleeve. The third positioning component 201 is a positioning pin. The shape of the positioning pin is adapted to the positioning pin sleeve. Optionally, four third positioning components 201 are respectively located at the four corners of the cell conveying carrier 200. Two second positioning components 103-9 are spaced apart along the X direction on the mounting plate 103-1. Four second positioning components 103-9 are disposed on the two mounting plates 103-1, and the four second positioning components 103-9 are compatible with the four third positioning components 201.

[0233] Optionally, the mounting plate 103-1 is provided with a second support portion 103-11, which supports the battery cell conveying carrier 200. The second support portion 103-11 is spaced apart from the second positioning member 103-9. Optionally, one second positioning member 103-9 corresponds to two second support portions 103-11, and the second positioning member 103-9 is located between the two second support portions 103-11. The second positioning member 103-9 can be higher or lower than the second support portion 103-11 under the drive of the second positioning member cylinder 103-10.

[0234] As described above, the first positioning member 103-6 and the second positioning member 103-9 cooperate to achieve precise positioning of the battery cell transport carrier 200. The rolling member 103-4 abuts against the battery cell transport carrier 200 as it continues to rise, thereby supporting the rise of the battery cell transport carrier 200 and creating a gap between the battery cell transport carrier 200 and the first support part 103-3. The first positioning member 103-6 achieves positioning of the battery cell transport carrier 200 in the Y direction, and the second positioning member 103-9 achieves precise point-to-point positioning of the battery cell transport carrier 200 in the X and Y directions.

[0235] When the conveying mechanism 103 is in operation with the battery cell conveying carrier 200, it first needs to position the carrier. During coarse positioning, the rolling element 103-4 on the roller mounting plate 103-5 rises, at which point the battery cell conveying carrier 200 is disengaged from the support of the rolling element 103-4 by the first support part 103-3. At the same time, the cylinder rod of the first positioning element cylinder 103-7 extends, and the V-block 103-8 installed on the first positioning element 103-6 performs coarse positioning of the battery cell conveying carrier 200 in the Y direction. The second positioning element cylinder 103-10 drives the second positioning element 103-9 to dock with the third positioning element 201, achieving multi-point positioning of the battery cell conveying carrier 200, thereby realizing precise positioning of the battery cell conveying carrier 200 in the X and Y directions.

[0236] Optionally, the conveying mechanism 103 is also equipped with an RFID reader / writer 103-14. The RFID reader / writer 103-14 can read the information of the code carrier 203 installed on the cell conveying carrier 200 and upload the information to the MES system.

[0237] The transverse assembly 100 also includes a frame 104, with a full positioning mechanism 101, a long guide rail 102, and a conveying mechanism 103 mounted on the frame 104. The conveying mechanism 103 is used to position and transport the battery cell transport carrier 200. Empty battery cell transport carriers 200 are transported from the left or right preparation position to the working position. After stacking, the stacked battery cell modules are transported back to the left or right preparation position. The two sets of full positioning mechanisms 101 on the left work together to guide and position the battery cells to be stacked on the left battery cell transport carrier 200. The two sets of full positioning mechanisms 101 on the right also work together to guide and position the battery cells to be stacked on the right battery cell transport carrier 200. The frame connector 105 connects the left and right frames 104 together, and the air source assembly 106 provides an adjustable and stable air source for the pneumatic components of the stacking transverse assembly 100. The conveying mechanism 103 is mounted on a slider of four long guide rails 102. It is powered by a transverse drive 103-2 and is driven by the meshing of rollers and racks 103-13. The battery cells are guided by the full positioning mechanism 101 and then stacked into the slots 101-2 of the positioning plate 101-11.

[0238] like Figures 6-7 As shown, the cell transport carrier 200 is used to carry and transport cells and stacked modules according to different process requirements.

[0239] like Figure 6 As shown, the cell transport carrier 200 is equipped with a retaining rod 202. After the cells are stacked, the retaining rod 202 presses the cell modules together, ensuring that the position of the cell modules does not change during transport from the stacking system to other machines. Optionally, the cell transport carrier 200 needs to be positioned before leaving the preparation position and after entering the preparation position. The retaining rod 202 is located above the cell transport carrier 200, and the retaining rod 202 and the cell transport carrier 200 together constitute upper and lower limits for the cells. Optionally, the installation position of the retaining rod 202 on the cell transport carrier 200 is adjustable.

[0240] like Figure 7 As shown, the battery cell transport carrier 200 is equipped with a code carrier 203. The code carrier 203 is located below the battery cell transport carrier 200. The code carrier 203 can interface with the RFID reader / writer head 103-14.

[0241] like Figure 8As shown, the restraint assembly 300 includes a restraint mechanism frame 301, a retaining rod grabbing mechanism 302, and a retaining rod pressing mechanism 303. The retaining rod grabbing mechanism 302 and the retaining rod pressing mechanism 303 are mounted on the restraint mechanism frame 301. The linear module of the restraint mechanism can drive the retaining rod grabbing mechanism 302 and the retaining rod pressing mechanism 303 to move together to a suitable position, thereby clamping and pressing down the retaining rod 202 on the cell delivery carrier 200.

[0242] like Figure 1 As shown, the detection assembly 400 is located on the side of the restraint assembly 300 near the stacking assembly 500. Figure 9 As shown, the detection assembly 400 includes a plasma cleaning mechanism and a detection mechanism. The detection mechanism can automatically detect the size and position of the battery tray on the transport carrier according to process requirements, and the plasma cleaning mechanism can automatically perform plasma cleaning on the tray. The two first columns 401 of the detection assembly 400 are spaced apart along the Y direction, and a first crossbeam 402 is installed between the two first columns 401, with the first crossbeam 402 located above the long guide rail 102. A second linear module 404 is provided on the first crossbeam 402, and both the plasma cleaning mechanism and the detection mechanism are installed on the second linear module 404.

[0243] The detection camera 411 is mounted on the camera mounting plate 412, which is mounted on two transition plates 409. The transition plates 409 are mounted on the plasma mounting plate 408, and the plasma cleaning head assembly 410 is also mounted on the plasma mounting plate 408. A slider on the plasma guide rail 407 is mounted on the plasma mounting plate 408. The plasma cleaning head assembly 410 and the detection camera 411 can slide on the plasma guide rail 407, with a limiting plate 406 limiting the sliding distance. Simultaneously, by adjusting the studs of the buffer guide rod assembly 413, the elasticity of the internal compression spring can be adjusted, providing cushioning in case the plasma cleaning head assembly 410 accidentally impacts an object, preventing damage to the plasma cleaning head assembly 410. The plasma guide rail 407 is mounted on the module adapter plate 405, which is mounted on the second linear module 404. The second linear module 404 can drive the plasma cleaning head assembly 410 and the detection camera 411 to move in the Z-axis direction. The second linear module 404 is mounted on the module adapter plate 405, and the module adapter plate 405 is mounted on the second linear module guide rail 403. The second linear module guide rail 403 can drive the entire mechanism to move along the Y direction.

[0244] like Figure 1As shown, two stepping mechanisms are provided on both sides of the transverse assembly 100 along the X direction. The stepping mechanisms are mainly used to ensure that the stacked cells are fully in contact with the cell transport carrier 200 and to press and position the cells in the Z-axis direction. The stepping mechanisms are provided with two stepping blocks 605 spaced apart along the Y direction. The two stepping blocks 605 operate synchronously, intermittently pressing on both sides of the cell. The stepping mechanisms include a first stepping mechanism 600 and a second stepping mechanism 700. The first stepping mechanism 600 and the second stepping mechanism 700 are respectively located in front of the moving direction of the full positioning mechanism 101 on both sides. After the cells are stacked by the stacking assembly 500 and the cell transport carrier 200 moves forward one unit distance, the stacked cells are pressed down to ensure that they are stacked in place.

[0245] like Figure 10 As shown, the main frame of the first stepping mechanism 600 includes a second column 601 and a second crossbeam 602. The overall structure of the second stepping mechanism 700 is basically the same as that of the first stepping mechanism 600, except that the main frame of the second stepping mechanism 700 does not have a column, but is directly mounted on the stacking assembly 500 via a crossbeam. The bottom surface of the stepping block 605 directly contacts the narrow surface of the battery cell. To prevent damage to the insulation film of the battery cell, the bottom surface of the stepping block 605 is coated with rubber. The stepping block 605 is mounted on the stepping cylinder 604, and moves in the Z-axis direction by the drive of the stepping cylinder 604. A buffer 603 is provided on the stepping cylinder 604. By adjusting the height of the buffer 603, the stepping mechanism can adapt to battery cells of various heights. Figure 11 As shown, the step cylinder 604 is mounted on the second adjusting block 606, which is mounted on the slider of the step guide rail 607. A rectangular slot is formed on the push block 614 to limit the rollers of the cam follower mounted on the second adjusting block 606, allowing the second adjusting block 606 to slide along the Y direction to accommodate cells of different lengths. Furthermore, the push block 614 is mounted on the step linear module 608, and under the drive of the step linear module 608, it can move the step pressure block 605 along the X direction. The step guide rail 609 is mounted on the step connecting plate 610, which is mounted on the sliders of the step guide rail 609 on the left and right sides respectively. Pulling the indexing pin 612 out of the positioning pin bushing 613 allows manual pushing to move the step pressure block 605 in the X direction. The indexing pin 612 is mounted on the step mounting block 611. The step linear module 608 is installed on the second crossbeam 602 of the stepping mechanism. When the battery cell needs to be changed, the X and Z directions of the step pressure block 605 can be manually adjusted, and the Y direction position of the step pressure block 605 can be automatically adjusted by the step linear module 608.

[0246] like Figure 12-13As shown, the stacking assembly 500 is disposed at the middle of the long guide rail 102 along the X direction. The stacking assembly 500 includes a column 501 and a stacking frame 502 disposed above the long guide rail 102. The stacking frame 502 extends along the Y direction, and a limit block is provided at the end of the stacking frame 502.

[0247] The stacking assembly 500 includes stacking grippers 514 capable of moving along the Z-direction. Two sets of stacking grippers 514 are spaced apart along the Y-direction. The two sets of stacking grippers 514 work together to achieve continuous, alternating positioning and gripping of battery cells. Specifically, the two sets of stacking grippers 514 are driven by the gripper linear module 507 to alternately move to the stacking position along the Y-direction, and move between the stacking position and the unloading position under the drive of the gripper drive 509, thereby continuously stacking battery cells into the battery cell transport carrier 200 at predetermined time intervals. The time interval for stacking and unloading cells by the stacking grippers 514 is adapted to the translation interval of the battery cell transport carrier 200. The battery cell transport carrier 200 can achieve a shorter translation interval to achieve high-speed stacking.

[0248] The stacking gripper 514 can move in the Z direction under the drive of the gripper drive 509. The cylinder of the gripper drive 509 is connected to the connecting block 512 of the first support plate 505. The stacking gripper 514 is mounted on two guide shafts 503 and a floating joint 513, with the other end of the floating joint 513 mounted on the output shaft of the gripper drive 509. During the movement of the stacking gripper 514 under the drive of the gripper drive 509, it is guided by the guide shafts 503. Optionally, the first mounting sleeve 504 and the second mounting sleeve 506 are mounted to the connecting block 512, and the guide shaft 514-3 is movably inserted into the first mounting sleeve 504 and the second mounting sleeve 506, and is movably connected to the connecting block 512. A limit plate 508 is provided above the guide shaft 514-3 to limit the lowest position of the guide shaft 514-3 and prevent the stacking gripper 514 from coming off the second support plate 514-1.

[0249] A crash barrier 511 is installed on the side of the first support plate 505 near the middle stacking position, and a buffer block 510 is fixed to the end face of the crash barrier 511.

[0250] like Figure 13As shown, the stacking gripper 514 includes large-face grippers 514-10 spaced apart along the X direction and length clamps 514-14 spaced apart along the Y direction. The large-face grippers 514-10 clamp and position the large face of the battery cell. The length clamps 514-14 position the battery cell in the length direction (Y direction) and thickness direction (X direction). The two sets of large-face grippers 514-10 and the two sets of length clamps 514-14 constitute the clamping space for the battery cell. When the stacking gripper 514 picks up the battery cell from the transfer mechanism 800, the left and right length grippers 514-14 are in the open state, the lifting cylinder 514-13 is in the lowering state, and the large surface gripper 514-10 is also in the open state. Then, the stacking gripper 514 descends along the Z direction to the picking position, and the large surface grippers 514-10 on the left and right sides clamp the large surface of the battery cell. The large surface grippers 514-10 clamp the cover plate surface of the battery cell, and the boss on the battery cell is also positioned in the waist-shaped groove of the large surface gripper 514-10. Then, the gripper drive 509 drives the stacking gripper 514 to rise to the safe position along the Z direction. Under the drive of the gripper linear module 507, it moves to the top of the stacking position. At this time, the stacking gripper 514 descends along the Z direction, and the large-face gripper 514-10 opens simultaneously, and the lifting cylinder 514-13 rises to the rising position. Finally, the stacking gripper 514 continues to descend along the Z direction, and the clamped battery cell enters the slot 101-2 through the guide of the positioning plate 101-1. After the gripper drive 509 reaches the set position in the Z direction, the length clamp 514-14 is released at the same time, and the battery cell is stacked on the battery cell conveying carrier 200, completing the stacking process of one battery cell.

[0251] The length clamp 514-14 is mounted on the clamping block connecting plate 514-15, which is mounted on the slider of the second jaw guide rail 514-17 of the length clamp. The second jaw guide rail 514-17 is fixed to the mounting support 514-18. The clamping block connecting plate 514-15 can slide in the Z direction, and the compression spring 514-16 provides buffering within a certain distance in the Z direction. The mounting support 514-18 is fixed to the slide plate 514-19, which is mounted on the first jaw guide rail 514-7 and moves in the Y direction under the drive of the second clamping side cylinder 514-23. The third connecting plate 514-20 is mounted on the slide plate 514-19, and the clamping rod 514-21 is mounted on the third connecting plate 514-20, with its other end connected to the second clamping side cylinder 514-23 via the second floating joint 514-22. A large-face gripper 514-10 is mounted on a large-face clamping cylinder 514-9. A proximity sensor 514-11 is installed on the large-face gripper 514-10 to detect whether it is clamping a battery cell. The large-face clamping cylinder 514-9 is mounted on a first connecting plate 514-8, which is mounted on a base plate 514-24. A lifting cylinder 514-13 is fixed to a second support plate 514-1 via a mounting hole on its top, through a second connecting plate 514-12. The side of the lifting cylinder 514-13 is mounted on the base plate 514-24 via an adapter plate 514-20. The lifting cylinder 514-13 can drive the large-face clamping cylinder 514-9 mounted on the base plate 514-24 to rise and fall. During the movement of the lifting cylinder 514-13, it is guided by the linear bearing 514-2 and the guide shaft 514-3, which is also mounted on the base plate 514-24. The first clamping side cylinder 514-4 is mounted on the second support plate 514-1 and connected to the reference block 514-6 through the first floating joint 514-5, used to drive the reference side length clamp 514-14 to move along the Y direction. Different mounting positions are provided on the base plate 514-24 and the slide plate 514-19 to accommodate the clamping of battery cells of different lengths (400-1200mm). In this application, the cooperation of the first clamping side cylinder 514-4 and the second clamping side cylinder 514-23 enables the two length clamps 514-14 to move closer or further apart along the Y direction, thereby realizing the picking and placing of battery cells.

[0252] like Figure 14 As shown, it also includes a transfer mechanism 800. The transfer mechanism 800 is disposed on the side of the stacking assembly 500. Two sets of transfer mechanisms 800 are arranged at intervals along the X and / or Y directions. Optionally, the two sets of transfer mechanisms 800 correspond to two sets of stacking assemblies 500. The transfer mechanism 800 is located above the long guide rail 102 through the arrangement of the column 801 and the mounting plate 802.

[0253] Two transfer mechanisms 800 are mainly used to transfer battery cells. After the battery cells are transported from other mechanisms, the transfer mechanism 800 clamps and fixes the battery cells to a preset position, waiting for the stacking gripper 514 to pick them up. A fixing block 808 and a cylinder 805 are provided on the fixing plate 804. The cylinder rod of the cylinder 805 is connected to a clamping block 806, which moves together with the cylinder rod. The fixing block 808 and the clamping block 806 are arranged opposite to each other. When the cylinder rod of the cylinder 805 extends, the battery cell is clamped between the fixing block 808 and the clamping block 806. Optionally, the oppositely arranged fixing blocks 808 and clamping blocks 806 are arranged in multiple sets at intervals along the Y direction. A proximity sensor 807 is provided on the side of the fixing block 808 facing the battery cell. The proximity sensor 807 is used to detect whether the battery cell is clamped in place. The fixing plate 804 is mounted on the slider of the guide rail 803. The fixed plate 804 moves together with the adapter plate 809 under the drive of the adapter plate drive 810. During normal operation, the adapter plate drive 810 first drives the fixed plate 804 to the set feeding position. After the feeding device places the battery cell in place and clamps it, the adapter plate drive 810 moves to the picking position, waiting for the stacking gripper 514 to pick up the battery cell.

[0254] The cell stacking system provided in this application enables high-speed and high-precision cell stacking. Before cell stacking, the cell transport carrier 200 enters the transport mechanism 103 located in the preparation position from the left or right entrance in the X direction of the stacking system via the transverse assembly 100. Precise positioning of the cell transport carrier 200 and the transport mechanism 103 is achieved through the first positioning element 103-6 and the second positioning element 103-9. Battery tray qualification testing can be performed according to process requirements. The full positioning mechanism 101 on either the left or right side and the cell transport carrier 200 move along the long guide rail 102 driven by the transverse drive element 103-2. The cell transport carrier 200 undergoes plasma cleaning when passing through the detection assembly 400. After cleaning, the cell transport carrier 200 moves to the working position. Upon receiving the carrier arrival signal, a stacking gripper 514 moves to the corresponding transfer mechanism 800 to pick up the cells and stack them into the cell transport carrier 200. After the battery cell is stacked into the first slot 101-2 of the positioning plate 101-1, the battery cell transport carrier 200 moves one unit. Another stacking gripper 514 stacks the battery cell into the second slot 101-2. The two stacking grippers 514 stack alternately. According to this action logic, the battery cells are stacked onto the transport carrier sequentially. During the stacking process, after each movement of the battery cell transport carrier 200, the stepping mechanism actuates to ensure that the bottom of the battery cell rests completely on the transport carrier's receiving surface.

[0255] This application also provides a battery production line, including the aforementioned cell stacking system.
