[0038] Example 1

[0039] Reference Figure 1-8As shown in the figure: A flexible tooling for assembling a tram battery pack, including a feeding device 1. The bottom of the feeding device 1 is fixedly connected to a bearing platform 2. One end of the feeding device 1 is movably connected to a containing device 3. The top of the containing device 3 is movably connected to an assembling device 4. One side of the containing device 3 is movably connected to a receiving device 5. The assembling device 4 includes a first support frame 41, a second support frame 411 and a third support frame 413. The first support frame 41, the second support frame 411 and the third support frame 413 are located at the edge of the containing device 3. A limiting platform 42 is fixedly installed at the top of the first support frame 41. One side of the limiting platform 42 is movably connected to a movable side rod 43. The other end of the movable side rod 43 is fixedly installed with a limiting plate 44. A transmission rod 45 is movably installed inside the limiting platform 42. One end of the transmission rod 45 is rotatably connected inside the limiting plate 44. The other end of the transmission rod 45 is fixedly connected to a transfer platform 46. The transfer platform 46 is located on the other side of the limiting platform 42. One side of the transfer platform 46 is movably connected to an electric slide 47. One side of the electric slide 47 is slidably connected to an extension bracket 48. The bottom of the extension bracket 48 is fixedly connected to a hollow bracket 49. The other end of the hollow bracket 49 is movably installed with a first material taking plate 410. The first material taking plate 410 is located directly above the containing device 3. A second material taking plate 412 is movably installed at the top of the second support frame 411. The second material taking plate 412 is located on one side of the first material taking plate 410. A transfer bracket 414 is fixedly installed at the top of the third support frame 413. A limiting block 415 is fixedly installed at one end of the transfer bracket 414.

[0045] As Figure 1-8As shown, the receiving device 5 includes a fixed frame 51. On one side of the fixed frame 51, a plurality of positioning rods 52 are fixedly installed.

[0046] In this embodiment, the fixed frame 51 is used to determine the position of the entire receiving device 5. The receiving basket 56 is arranged on the side of the carrier 36. When the carrier 36 rotates, the control box 54 controls the triangular bracket 53 to move along the direction of the positioning rod 52, and uses the robotic arm 55 to push the assembled battery on the carrier 36 into the receiving basket 56.

[0047] Embodiment 4

[0048] As Figure 1-8 shown, the feeding device 1 includes a raw material storage box 11. On one side of the raw material storage box 11, a conveying table 12 is movably connected. On the top of the conveying table 12, a vertical support table 13 is fixedly connected. On both sides of the conveying table 12, partition support seats 14 are fixedly connected. On the top of the partition support seats 14, a rotating table 15 is movably installed. At the bottom of the rotating table 15, a rectangular plate 16 is movably connected. On one side of the rectangular plate 16, a swivel joint 17 is movably connected. On one side of the swivel joint 17, a partition rod 18 is rotatably connected. The partition rod 18 is located on both sides of the conveying table 12. On the top of the conveying table 12, a docking table 110 is movably installed. One end of the docking table 110 is fixedly connected to a conveying guide rail 111. The other end of the conveying guide rail 111 is movably connected to the raw material storage box 11. On one side of the vertical support table 13, a marking table 19 is movably installed. The marking table 19 is located directly above the conveying guide rail 111.

[0049] In this embodiment, the raw material storage box 11 is used to store the components to be assembled. The components are sent to the docking table 110 at the other end of the conveying table 12 through the conveying guide rail 111. During this process, the marking table 19 on the vertical support table 13 will detect the marks of each component to proofread the total number of required components. When the component moves to the docking table 110, the rotating table 15 on the partition support seat 14 starts to rotate, rotates the rectangular plate 16 to the position of the docking table 110, and then the swivel joint 17 rotates, and uses the partition rod 18 to send the components on the docking table 110 to the carrier 36. Each partition rod 18 can only push one component at a time to prevent the situation of too many components.

[0050] The device and its working principle: When in use, first, the components are sent to the docking station 110 at the other end of the conveying table 12 through the conveying guide rail 111. During this process, the marking table 19 on the vertical support table 13 will detect the marks of each component to check the total quantity of the required components. When the component moves to the docking station 110, the rotating table 15 on the separating support seat 14 starts to rotate, rotating the rectangular plate 16 to the position of the docking station 110. Subsequently, the adapter 17 rotates, and the separating rod 18 is used to send the components on the docking station 110 to the bearing table 36. Each separating rod 18 can only push one component at a time to prevent the situation of excessive component quantity. The bearing table 36 is positioned by the positioning end 35 and can rotate around the positioning end 35 as a whole to change the positions of the respective limit blocks 37, facilitating the adjustment of the battery state. The positioning end 35 is controlled by the drive motor 34. Subsequently, the first material-taking plate 410 takes a part of the components, and the second material-taking plate 412 takes another part of the raw materials. Under the pressing of the pressing plate 420, the components and the raw materials are assembled together. The first material-taking plate 410 is located above the material-forming device 3 and is mainly used for assembling the top components. During its movement, the movable side rod 43 can push the transmission rod 45 to move through the limit plate 44, so that the transfer platform 46 leaves the limit platform 42. At the same time, the extension bracket 48 can also move along the direction of the electric slide 47, and the electric slide 47 itself moves along the transfer platform 46 to achieve position adjustment, facilitating the adjustment of the assembly position and direction of the components. The second material-taking plate 412 is located on the side of the bearing device 3 and is used for the assembly of the components on the side. The pressing plate 420 can be adjusted to various directions and angles under the rotation and movement of the direction-changing bracket 419 to fix the components and ensure the stability of each component. The electric slider 416 moves along the direction of the transfer bracket 414 to directly change the positions of the separating baffle 417 and the installation connection table 418. After the assembly is completed, the bearing table 36 rotates again, and the control box 54 controls the triangular bracket 53 to move along the direction of the positioning rod 52, and the robotic arm 55 is used to push the assembled battery on the bearing table 36 into the receiving basket 56.
