[0090] The electric cell conveying carrier 200 is used to carry the electric cell 204. Optionally, the electric cell conveying carrier 200 is provided with a tray 205.

[0091] As shown in FIGS. 3 to 7, the full positioning mechanism 101 includes a positioning clamping plate 101-1 for clamping the electric cell 204.

At least part of the positioning clamping plate 101-1 is located above the electric cell conveying carrier 200. The electric cell conveying carrier 200 achieves limiting of the bottom of the electric cell 204.

[0106] As shown in FIG. 5, the conveying mechanism 103 includes a mounting plate 103-1 and a transverse driving member 103-2. The mounting plate 103-1 is movably connected to the long guide rail 102. Optionally, the transverse driving member 103-2 is configured as a servo motor, and the motor shaft of the servo motor is connected with a driving roller. The transmission is achieved by the meshing of the roller and the rack 103-13. The battery cell conveying carrier 200 and the full positioning mechanism 101 are mounted above the mounting plate 103-1. The transverse driving member 103-2 is used to drive the mounting plate 103-1 to move along the long guide rail 102. The full positioning mechanism 101 translates along the X direction with the mounting plate 103-1 at a predetermined time interval and a predetermined distance.

[0107] The mounting plate 103-1 is provided with a first support portion 103-3 for supporting the battery cell conveying carrier 200. It can be understood that the battery cell conveying carrier 200 can be placed above the first support portion 103-3. The mounting plate 103-1 is also provided with a rolling member 103-4.

When the rolling member 103-4 is higher than the first support portion 103-3, the battery cell conveying carrier 200 can be separated from the first support portion 103-3. The rolling member 103-4 can be rotatably connected with the battery cell conveying carrier 200, so as to reduce the resistance when the battery cell conveying carrier 200 is positioned.

[0108] As shown in FIG. 5, the conveying mechanism 103 further includes a positioning member 107. Through the positioning member 107, the battery cell conveying carrier 200 can be precisely positioned along the Y direction and precisely positioned along the X direction.

[0109] The positioning member 107 comprises a first positioning member 103-6. The first positioning member 103-6 is arranged on the side of the battery cell conveying carrier 200. The first positioning member 103-6 is driven to move along the Y direction by the first positioning member air cylinder 103-7, so as to realize the positioning of the battery cell conveying carrier 200 along the Y direction. Two groups of first positioning members 103-6 are respectively arranged on the two sides of the battery cell conveying carrier 200.

The two-point contact between the V-shaped block 103-8 and the battery cell conveying carrier 200 facilitates the positioning of the battery cell conveying carrier 200 and reduces the error.

[0110] The positioning member 107 comprises a second positioning member 103-9. A third positioning member 201 is arranged below the battery cell conveying carrier 200. The third positioning member 201 is capable of being connected to the second positioning member 103-9 in a matched manner.

[0112] As known from the foregoing, the first positioning member 103-6 and the second positioning member 103-9 cooperate to realize the accurate positioning of the battery cell conveying carrier 200. The rolling member 103-4 abuts against the battery cell conveying carrier 200 to continue to rise, thereby supporting the battery cell conveying carrier 200 to rise, so that the battery cell conveying carrier 200 is spaced apart from the first support portion 103-3. The first positioning member 103-6 realizes the positioning of the battery cell conveying carrier 200 along the Y direction, and the second positioning member 103-9 realizes the accurate point-to-point positioning of the battery cell conveying carrier 200 along the X direction and the Y direction.

[0113] The conveying mechanism 103 needs to position the carrier first when conveying the battery cell carrier 200. During rough positioning, the rolling elements 103-4 on the rolling plate 103-5 are lifted, and at this time, the battery cell carrier 200 is separated from the first support part 103-3 supported by the rolling elements 103-4. The cylinder rod of the first positioning cylinder 103-7 is extended at the same time, and the V-shaped block 103-8 installed on the first positioning part 103-6 performs rough positioning of the battery cell carrier 200 in the Y direction.

[0122] As shown in FIG. 1, two stepping mechanisms 710 are arranged on both sides of the horizontal movement assembly 100 along the X direction. The stepping mechanism 710 is mainly used to ensure that the stacked battery cell 204 is in full contact with the battery cell conveying carrier 200, and to position the battery cell 204 in the Z-axis direction. The stepping mechanism 710 is provided with two stepping blocks 605 arranged along the Y direction. The two stepping blocks 605 act synchronously and intermittently press on both sides of the battery cell 204. The stepping mechanism 710 includes 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 battery cell 204 is stacked to the battery cell conveying carrier 200 by the stacking assembly 500 and moves forward by one unit distance, the stacked battery cell 204 is pressed to ensure that it is stacked in place.

[0123] As shown in FIG. 10, the main frame of the first stepping mechanism 600 includes a second upright column 601 and a second crossbeam 602. The overall mechanism 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 has no upright column, but is directly installed on the stacking assembly 500 through the crossbeam. The bottom surface of the stepping block 605 directly contacts the narrow surface of the battery cell 204. In order to prevent the insulating film of the battery cell 204 from being broken, the bottom surface of the stepping block 605 is encapsulated. The stepping block 605 is installed on the stepping cylinder 604, and moves in the Z-axis direction by the driving of the stepping cylinder 604.

[0124] As shown in FIGS. 12-13, the stacking assembly 500 is arranged at the middle of the long guide rail 102 in the X direction. The stacking assembly 500 includes a third upright column 501 and a stacking frame 502 arranged above the long guide rail 102. The stacking frame 502 extends in the Y direction, and the end of the stacking frame 502 is provided with a limiting block.

[0125] The stacking assembly 500 comprises stacking grippers 514 capable of moving along the Z direction. Two sets of stacking grippers 514 are arranged at intervals along the Y direction. The two sets of stacking grippers 514 are used in cooperation to achieve continuous, alternating positioning and grabbing of the battery cells 204. Specifically, the two sets of stacking grippers 514 are driven by the gripper linear module 507 to alternately run to the stacking position along the Y direction, and are driven by the gripper driving member 509 to move between the stacking position and the feeding position, so as to continuously stack the battery cells 204 into the battery cell conveying carrier 200 at a predetermined time interval. The time interval of the stacking grippers 514 for stacking the battery cells 204 is matched with the translation interval of the battery cell conveying carrier 200. The battery cell conveying carrier 200 can achieve a shorter translation interval to realize high-speed stacking.

[0126] The stacking grippers 514 can move along the Z direction under the driving of the gripper driving member 509. The cylinder body of the gripper driving member 509 is connected to the connecting block 512 of the first support plate 505. The stacking grippers 514 are installed on the two guide shafts 503 and the floating joint 513, and the other end of the floating joint 513 is installed on the output shaft of the gripper driving member 509. During the movement of the stacking grippers 514 under the driving of the gripper driving member 509, the stacking grippers 514 are guided by the guide shafts 503.

[0127] The first support plate 505 is provided with an anti-collision plate 511 near one side of the middle stacking position, and the end surface of the anti-collision plate 511 is fixed with a buffer block 510.

[0128] As shown in FIG. 13, the stacking gripper 514 includes large surface grippers 514-10 arranged at intervals along the X direction, and length grippers 514-14 arranged at intervals along the Y direction. The large surface grippers 514-10 clamp and position the large surface of the battery cell 204. The length grippers 514-14 position the length direction (Y direction) and the thickness direction (X direction) of the battery cell 204. The two sets of large surface grippers 514-10 and the two sets of length grippers 514-14 form a clamping space for the battery cell 204. When the stacking gripper 514 takes the battery cell 204 from the transfer mechanism 800, the left and right length grippers 514-14 are in an open state, the lifting cylinder 514-13 is in a lowered state, and the large surface grippers 514-10 are also in an open state. Then, the stacking gripper 514 as a whole is lowered along the Z direction to a taking position, the left and right large surface grippers 514-10 clamp the large surface of the battery cell 204, the large surface grippers 514-10 clamp the cover plate surface of the battery cell 204, and the boss on the top of the battery cell 204 is also positioned in the waist-shaped groove of the large surface gripper 514-10. Then, the gripper driving member 509 drives the stacking gripper 514 to rise along the Z direction to a safe position, and moves to directly above the stacking position under the drive of the gripper linear module 507. At this time, the stacking gripper 514 is lowered along the Z direction, and the large surface gripper 514-10 is opened synchronously, and the lifting cylinder 514-13 is lifted to a lifting position. Finally, the stacking gripper 514 continues to be lowered along the Z direction, the clamped battery cell 204 enters the clamping groove 101-2 through the guidance of the positioning clamping plate 101-1, and after the Z direction of the gripper driving member 509 reaches the set position, the length gripper 514-14 is loosened at the same time, the battery cell 204 is stacked on the battery cell conveying carrier 200, and the stacking process of one battery cell 204 is completed.

[0129] The length clamps 514-14 are installed on the clamp block connecting plate 514-15, which is installed on the slider of the length clamp second jaw guide rail 514-17, which is fixed on the mounting support 514-18. The clamp block connecting plate 514-15 can slide in the Z direction, and the buffer within a certain distance in the Z direction is realized by the compression spring 514-16. The mounting support 514-18 is fixed on the sliding table plate 514-19, which is installed on the first jaw guide rail 514-7 and moves in the Y direction under the action of the second clamping side cylinder 514-23; the third connecting plate 514-20 is installed on the sliding table plate 514-19, and the pressing rod 514-21 is installed on the third connecting plate 514-20, and the other end is connected to the second clamping side cylinder 514-23 through the second floating joint 514-22. The large surface clamping jaw 514-10 is installed on the large surface clamping cylinder 514-9, and the first proximity sensor 514-11 is arranged on the large surface clamping jaw 514-10 to detect whether the battery cell 204 is clamped. The large surface clamping cylinder 514-9 is installed on the first connecting plate 514-8, which is installed on the bottom plate 514-24; the hole on the lifting cylinder 514-13 is fixed on the second support plate 514-1 through the second connecting plate 514-12, and the side of the lifting cylinder 514-13 is installed on the bottom plate 514-24 through the adapter. The large surface clamping cylinder 514-9 installed on the bottom plate 514-24 can be driven to rise and fall by the lifting cylinder 514-13. During the movement of the lifting cylinder 514-13, the linear bearing 514-2 and the guide shaft 514-3 are used for guiding, and the guide shaft 514-3 is also installed on the bottom plate 514-24. The first clamping side cylinder 514-4 is installed on the second support plate 514-1, and is connected with the reference block 514-6 through the first floating joint 514-5 to drive the reference side length clamp 514-14 to move in the Y direction. Different mounting positions are arranged on the bottom plate 514-24 and the sliding table plate 514-19 to meet the clamping of battery cells 204 of different lengths (400-1200mm). In this disclosure, the first clamping side cylinder 514-4 and the second clamping side cylinder 514-23 cooperate to realize the mutual approach or separation of the two length clamps 514-14 in the Y direction, thereby realizing the taking and placing of the battery cell 204.

[0130] As shown in FIG. 14, the transfer mechanism 800 is also included. The transfer mechanism 800 is arranged at the side of the stacking assembly 500. Two sets of transfer mechanisms 800 are arranged at intervals in the X direction and / or the Y direction. Alternatively, the two sets of transfer mechanisms 800 correspond to the two sets of stacking assemblies 500. The transfer mechanism 800 is located above the long guide rail 102 through the arrangement of the fourth stand column 801 and the mounting plate 802.

[0131] The two sets of transfer mechanism 800 are mainly used for transferring the battery cell 204. After the battery cell 204 is transported from other mechanisms, the transfer mechanism 800 clamps and fixes the battery cell 204 to a preset position, and waits for the stacking clamp jaw 514 to clamp. The fixed block 808 and the air cylinder 805 are arranged on the fixed plate 804. The cylinder rod of the air cylinder 805 is connected with the pressing block 806, and the pressing block 806 moves with the cylinder rod of the air cylinder 805. The fixed block 808 and the pressing block 806 are oppositely arranged. When the cylinder rod of the air cylinder 805 is extended, the battery cell 204 is clamped between the fixed block 808 and the pressing block 806. Alternatively, the oppositely arranged fixed block 808 and pressing block 806 are arranged in multiple groups along the Y direction. The side of the fixed block 808 facing the battery cell 204 is provided with a second proximity sensor 807. The second proximity sensor 807 is used to detect whether the battery cell 204 is clamped in place. The fixed plate 804 is installed on the sliding block of the guide rail 803. The fixed plate 804 moves 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 move to a set unloading position. After the battery cell 204 is placed in place by the unloading device and clamped, the adapter plate drive 810 moves to a loading position, and waits for the stacking clamp jaw 514 to take the battery cell 204.

[0132] The battery cell stacking system 900 provided by the present disclosure can realize high-speed and high-precision stacking of the battery cell 204. Before the battery cell 204 is stacked, the battery cell conveying carrier 200 enters the conveying mechanism 103 located at the preparation position from the left or right entrance in the X direction of the stacking system through the transverse movement assembly 100. The first positioning member 103-6 and the second positioning member 103-9 are used to realize precise positioning of the battery cell conveying carrier 200 and the conveying mechanism 103. According to process requirements, the qualification of the battery tray 205 can be detected. The full positioning mechanism 101 of one of the left or right, and the battery cell conveying carrier 200 move along the long guide rail 102 under the drive of the transverse movement drive 103-2. The battery cell conveying carrier 200 is plasma cleaned when passing through the detection assembly 400. After cleaning, the battery cell conveying carrier 200 moves to the working position. After receiving the carrier in position signal, one stacking clamp jaw 514 moves to the corresponding transfer mechanism 800 to take the battery cell 204 and stack it into the battery cell conveying carrier 200. After the battery cell 204 is stacked into the set first clamping groove 101-2 of the positioning clamping plate 101-1, the battery cell conveying carrier 200 moves one unit. The other stacking clamp jaw 514 stacks the battery cell 204 into the second clamping groove 101-2. The two stacking clamp jaws 514 are stacked alternately. According to this action logic, the battery cell 204 is sequentially stacked into the conveying carrier. During the stacking process, after the battery cell conveying carrier 200 moves each time, the stepping mechanism 710 acts to ensure that the bottom of the battery cell 204 completely falls on the conveying carrier receiving surface.

[0133] As shown in Figure 15, this disclosure also provides a battery production line 910, including the above-mentioned cell stacking system 900.
