[0031] In order to make the purpose, technical solution and advantages of the utility model more clear, the utility model is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the utility model and are not used to limit the utility model.

[0032] In order to solve the technical problem in the prior art that when the AGV trolley transports the pallet with soft-pack battery cells and electrode sheets to the welding position, the soft-pack battery cells and electrode sheets are not placed horizontally, resulting in welding deviation of the soft-pack battery cells and electrode sheets by the welding robot arm, which has an adverse effect on the quality of the soft-pack battery, the utility model provides a support platform for welding soft-pack battery cells and electrode sheets, which can level the soft-pack battery cells and electrode sheets on the transport vehicle by changing the height difference between two support parts. The operation is simple and convenient, ensuring that the soft-pack battery cells and electrode sheets can be welded in a horizontal state, effectively avoiding welding deviation of the welding robot arm, and improving the quality of the soft-pack battery.

[0033] See also Figure 1 and Figure 2 , Figure 1 and Figure 2 It is a structural schematic diagram of a support platform for welding soft-pack battery cells and pole pieces in one embodiment of the utility model, wherein the support platform for welding soft-pack battery cells and pole pieces comprises a platform 1, a support driving part 3 and two support parts 2; the two support parts 2 are spaced apart on the same side of the platform 1 to form a conveying gap 2a between the two support parts 2, and the conveying gap 2a is used for a transport vehicle 8 for conveying materials to pass through, and the two support parts 2 can move in a vertical direction, and have a lifting position for moving upward to lift the transport vehicle 8 off the ground to level the materials, and have a downward movement to an evasive position for leaving the transport vehicle 8; the support driving part 3 is respectively connected to the two support parts 2 in driving relation, and can drive the two support parts 2 to move in a vertical direction respectively.

[0034] The utility model provides a support platform for welding soft-pack battery cells and electrode sheets. When the transport cart 8 moves to the position of the conveying gap 2a, if the operator finds that the soft-pack battery cells and electrode sheets on the transport cart 8 are not placed horizontally, the two support parts 2 can be driven upward by the support driving part 3 to push the transport cart 8, so that the transport cart 8 is lifted off the ground, and the soft-pack battery cells and electrode sheets on the transport cart 8 can be leveled by changing the height difference between the two support parts 2. The operation is simple and convenient, ensuring that the soft-pack battery cells and electrode sheets can be in a horizontal state for welding, effectively avoiding welding deviation of the welding robot arm, and improving the quality of the soft-pack battery.

[0035] It should be noted that, in one embodiment, two support parts 2 are arranged at intervals along the feeding direction of the transport vehicle 8 to further improve the flexibility of leveling. In another embodiment, two support parts 8 can be arranged at intervals on the same side of the conveying gap 2a.

[0036] In one embodiment, a carriage channel 1a is provided on the upper end surface of the platform 1, and two support parts 2 are installed on the upper end surface of the platform 1 and located on opposite sides of the carriage channel 1a, so that the conveying gap 2a is connected to the carriage channel 1a.

[0037] In this embodiment, a carriage channel 1a is provided on the upper end surface of the platform 1, and the conveying gap 2a is connected to the carriage channel 1a; thus, the rollers of the transport vehicle 8 can move along the carriage channel 1a to transport the transport vehicle 8 to the conveying gap 2a, which plays a guiding role, improves the conveying efficiency, and has a simple structure and saves costs. At the same time, the flange 81 at the upper end of the transport vehicle 8 is located above the upper end surface of the carriage channel 1a. When the transport vehicle 8 moves to the conveying gap 2a, the flange 81 of the transport vehicle 8 is pushed by the two support parts 2 at the conveying gap 2a to level the materials on the transport vehicle 8.

[0038] In one embodiment, see Figure 5 Two mounting grooves 1b are provided on the upper end surface of the platform 1, and the two mounting grooves 1b are located on opposite sides of the carriage channel 1a. The support driving part 3 includes two support driving cylinders 31, and the cylinder bodies of the two support driving cylinders 31 are respectively installed in the two mounting grooves 1b, and the telescopic rod 32 of each support driving cylinder is telescopically arranged in the vertical direction; the two support parts 2 are respectively installed on the telescopic rods 32 of the two support driving cylinders, and are located at one end of the telescopic rod 32 of the support driving cylinder away from the corresponding cylinder body.

[0039] In this embodiment, the lifting height of the support part 2 is adjusted by two support driving cylinders 31, the structure is simple and reliable, and the two support driving cylinders 31 are arranged in two installation grooves 1b to improve the compactness of the device.

[0040] In one embodiment, see Figure 3 and Figure 4 The support part 2 is a support seat 21, and the support seat 21 is provided with a connecting screw hole 21a. The end of the telescopic rod 32 supporting the driving cylinder away from the corresponding cylinder body is provided with an external thread so that it can be screwed into the connecting screw hole 21a, so that the support seat 21 and the telescopic rod 32 supporting the driving cylinder can be detachably connected.

[0041] In this embodiment, the support seat 21 is threadedly connected to the telescopic rod 32 supporting the driving cylinder. In this way, when the support seat 21 is worn and affects the leveling, the support seat 21 can be replaced in time to ensure effective leveling of the material, and the operation is simple and convenient.

[0042] In one embodiment, a suction cup 22 is disposed on the upper side of the support base 21 .

[0043] In this embodiment, when the support seat 21 pushes the transport cart 8, the air in the suction cup 22 is exhausted and can be adsorbed on the lower side of the flange 81 of the transport cart 8 to prevent the transport cart 8 from accidentally shaking after being lifted off the ground, thereby providing a reliable environment for welding by the welding robot arm. After welding is completed, when the support seat 21 is in the process of moving downward, after the transport cart 8 touches the ground, the suction cup 22 can be driven by the downward movement of the support seat 21 to detach from the transport cart 8, so that the transport cart 8 can travel normally. It should be noted that in one embodiment, the suction cup 22 is a negative pressure suction cup 22, the main body of which is made of a rigid material and is connected to a vacuum pump so that it can be sucked to a negative pressure by the vacuum pump, thereby sucking the flange 81 of the transport cart 8.

[0044] In one embodiment, see Figure 5 and Figure 6 The support platform for welding the soft-pack battery cell and the electrode piece also includes a clamping drive part 4 and two clamping parts 5. The two clamping parts 5 are located on opposite sides of the conveying gap 2a, and correspond to the two support parts 2 respectively, and are arranged above the adjacent support parts 2. The two clamping parts 5 can approach and move away from each other, and can clamp the material on the material tray when approaching each other. The clamping drive part 4 is respectively connected to the two clamping parts 5 for driving the two clamping parts 5 to approach and move away from each other.

[0045] In this embodiment, after the support part 2 adjusts the horizontality of the material, the two clamping parts 5 can be driven closer to each other through the clamping drive part 4 to clamp the soft-pack battery cells on the material tray to prevent the soft-pack battery cells from accidentally moving during welding and ensure the welding quality.

[0046] In one embodiment, the clamping drive part 4 includes two clamping drive cylinders 41, which are installed on opposite sides of the conveying gap 2a and are arranged above the support part 2. The telescopic rod of each clamping drive cylinder 41 is arranged in the horizontal direction and can extend into and withdraw from the conveying gap 2a; the clamping part 5 is a clamping seat 51, and the two clamping seats 51 are respectively arranged at one end of the telescopic rod of the two clamping drive cylinders 41 away from the corresponding cylinder body.

[0047] In this embodiment, the clamping drive unit 4 is configured as two clamping drive cylinders 41, and the two clamping drive cylinders 41 respectively drive the two clamping seats 51 to clamp and release the soft-pack battery cell, which has a simple and reliable structure. In addition, in order to prevent the clamping seat 51 from damaging the soft-pack battery cell, a rubber cushion 52 is provided on one side of each clamping seat 51 close to another clamping seat 51.

[0048] It should be noted that, in this solution, two mounting seats 11 are provided corresponding to the two clamping drive cylinders 41, and the two mounting seats 11 are provided on opposite sides of the carriage channel 1a, and correspond to the two supporting drive cylinders 31, and are located on the side of the adjacent supporting drive cylinder 31 away from the other supporting drive cylinder 31. The clamping drive cylinder 41 is installed on the upper side of the mounting seat 11, so as to be spaced apart from the supporting drive cylinder 31 in the upper and lower directions.

[0049] In one embodiment, the support platform for welding the soft-pack battery cell and the electrode piece also includes two groups of guide platforms 6, which are arranged on the platform 1 and are respectively located on the opposite sides of the conveying gap 2a and correspond to the two support parts 2. A ball 7 is provided on the side of the guide platform 6 away from the platform 1.

[0050] In this embodiment, a guide platform 6 is provided corresponding to the support arm, and a ball bearing 7 is provided on the upper end surface of the guide platform 6 to guide the movement of the flange 81 of the transport vehicle 8. Specifically, in this solution, each group of guide platforms 6 is provided with two, and the two guide platforms 6 in the same group are arranged at intervals on both sides of the support portion 2 in the transport direction of the transport vehicle 8, so that the transport vehicle 8 can move more smoothly at the transport gap 2a.

[0051] In order to better understand the present invention, the following Figures 1 to 6 The technical solution of the utility model is described in detail:

[0052] When the transport vehicle 8 moves to the position of the conveying gap 2a, the flange 81 of the transport vehicle 8 rolls and contacts the ball 7 of the guide platform 6. When the operator finds that the material is uneven, he starts the two support drive cylinders 31 to lift the two support seats 21, and drives the two support seats 21 to push the flange 81 of the transport vehicle 8, so that the suction cups 22 on the support seats 21 can be adsorbed on the lower side of the flange 81 and lift the transport vehicle 8 off the ground; then the soft-pack battery cells and pole pieces on the transport vehicle 8 can be leveled by adjusting the height difference of the two support seats 21. After the soft-pack battery cells and pole pieces are leveled, the welding robot arm is driven to weld the soft-pack battery cells and pole pieces to ensure that the soft-pack battery cells and pole pieces can be in a horizontal state, effectively avoiding welding deviations of the welding robot arm and improving the quality of the soft-pack battery. After welding is completed, the two support seats 21 are lowered by the two support driving cylinders 31 until the wheels of the transport vehicle 8 fall on the bottom of the carriage channel 1a and the suction cup 22 is separated from the flange 81. At this time, the flange 81 contacts the ball 7 on the guide platform 6, and then the transport vehicle 8 is started to move to the next workstation.
