[0002] A PACK assembly line refers to a power battery assembly production line, which mainly covers the assembly, testing, and packaging of battery clusters. On the PACK assembly line, a series of tasks need to be completed, including battery assembly, debugging, testing, accessory installation, parameter modification, and modification and repair.

[0003] Current PACK assembly lines primarily use AGVs to carry PACKs. However, this method requires operators to walk around the AGVs during assembly, and the AGVs may collide with operators during movement, posing a safety hazard. Furthermore, the low efficiency of AGV movement results in low overall assembly efficiency. To address these issues, PACK assembly lines can also use roller conveyors for transporting PACKs. However, this method still presents some problems. Because PACKs are generally large and electrical components are typically concentrated at the front or middle of the PACK layout, and operators stand on either side of the roller conveyor, the assembly position is far from the operators' positions, making assembly difficult. This not only reduces work efficiency but may also lead to occupational hazards due to fatigue from repetitive operations over long periods. Summary of the Invention

[0042] The battery pack flipping mechanism provided in this application includes a base support; a rotating component mounted on the base support; and a tray for supporting the battery pack. The rotating component is connected to the tray and drives the tray to rotate the battery pack, with the rotation angle ranging from 80 degrees to 110 degrees. By rotating the battery pack so that its front end faces the side of the roller conveyor, it facilitates operation of the electrical components at the front end of the battery pack by operators located on the side of the roller conveyor, which is more ergonomic, reduces the workload of operators, and improves the overall efficiency of the production line.

[0043] like Figures 1 to 3 As shown, one embodiment of this application provides a battery pack flipping mechanism, including:

[0044] Base support 100;

[0045] Rotating component 200 mounted on base bracket 100; and

[0046] The tray is used to carry the battery pack;

[0047] The rotating component 200 is connected to the tray and is used to drive the tray to rotate the battery pack. The rotation angle of the battery pack is 80 degrees to 110 degrees.

[0048] In practice, the battery pack flipping mechanism provided in this application is applied to a PACK assembly line that uses a roller conveyor flow method. Here, PACK refers to a battery pack, and the PACK assembly line is equipped with a roller conveyor, which can be regarded as a track for transporting battery packs. The flipping mechanism is located in the middle of the roller conveyor, that is, the battery pack is transferred from the upstream roller conveyor to the flipping mechanism, and after the flipping mechanism performs the corresponding process, it is transferred to the downstream roller conveyor.

[0049] The base support 100 is used to support the rotating component 200 and the tray. When the battery pack is transported from the upstream roller conveyor to the flipping mechanism, the battery pack is placed on the tray. Since the battery pack is generally large in size and the electrical components are generally concentrated at the front or middle of the battery pack, the rotating component 200 drives the tray to rotate, so as to rotate the battery pack by 80 to 110 degrees. For example, the battery pack can be rotated by any angle between 85, 90, 95 degrees or 80 to 110 degrees. As long as the distance between the personnel standing position and the part assembly position can be reduced, there is no limitation.

[0050] The battery pack flipping mechanism provided in this application includes a base support 100; a rotating component 200 disposed on the base support 100; and a tray for supporting the battery pack. The rotating component 200 is connected to the tray and drives the tray to rotate the battery pack, with the rotation angle being 80 to 110 degrees. By rotating the battery pack so that its front end faces the side of the roller conveyor, it facilitates the operation of the electrical components at the front end of the battery pack by operators located on the side of the roller conveyor, which is more ergonomic, reduces the workload of operators, and improves the overall efficiency of the production line.

[0051] In some embodiments, the rotating assembly 200 includes a drive disk 210, a claw 220, and a first drive member 230;

[0052] The drive disk 210 is rotatably mounted on the base bracket 100, and a number of protruding claws 220 are circumferentially distributed on the drive disk 210.

[0053] The first driving component 230 is mounted on the base bracket 100 and connected to the driving disk 210, and is used to drive the driving disk 210 to rotate.

[0054] The bottom of the tray is provided with a groove (not shown) that mates with the protruding claw 220.

[0055] When the tray is placed on the rotating assembly 200, the protruding claw 220 can be embedded in the groove. The first driving member 230 drives the driving disk 210. The rotation of the driving disk 210 will drive the protruding claw 220 to rotate, thereby driving the tray to rotate.

[0056] Furthermore, the battery pack flipping mechanism provided in this application also includes a flipping device 500, which is used to flip the battery pack so that the bottom surface of the battery pack faces upward.

[0057] This application further allows the battery pack to be flipped over so that the bottom of the battery pack faces upwards, making it easier for operators to perform assembly and other operations from the bottom of the battery pack.

[0058] Optionally, the tilting device 500 includes a lifting drive assembly 510, a tilting assembly 520, and a fork arm 530;

[0059] The fork arm 530 is used to grip the edge of the battery pack;

[0060] The flipping assembly 520 is connected to the fork arm 530 and is used to drive the fork arm 530 to flip.

[0061] The lifting drive assembly 510 is connected to the tilting assembly 520 and is used to drive the tilting assembly 520 to lift.

[0062] When flipping the battery pack, the flipping component 520 is first driven to descend, so that the fork arm 530 grabs the edge of the battery pack. Then, the flipping component 520 is driven to rise to a certain height, and then the flipping component 520 drives the battery pack to flip so that the bottom of the battery pack faces upward.

[0063] Optionally, the height of the flip component 520 can be set according to actual usage requirements. The height is sufficient to prevent the flip component 520 from colliding with other components when it flips the battery pack, and there is no limitation on this height.

[0064] Optionally, the lifting drive assembly 510 includes a lifting bracket 511, a lifting plate 512, and a lifting drive component;

[0065] The lifting plate 512 is connected to the tilting assembly 520 and is slidably connected to the lifting bracket 511.

[0066] The lifting drive component is connected to the lifting plate 512 and is used to drive the lifting plate 512 to lift and lower, thereby driving the tilting component 520 to lift and lower.

[0067] The first driving component 230 and the lifting driving component can be motors or other devices that can output power to drive the corresponding components to move, without limitation.

[0068] Furthermore, the lifting drive assembly 510 also includes a counterweight 513, which is connected to the lifting plate 512 via a counterweight rope.

[0069] During implementation, the counterweight rope can be made of steel cable, chain or other rope. The lifting plate 512 is raised and lowered by the counterweight block 513 and the counterweight rope, which in turn raises and lowers the fork arm 530.

[0070] Optionally, the fork arm 530 includes a cross arm 531, a gripper 532, and a retraction drive (not shown).

[0071] The horizontal arm 531 is mounted on the lifting plate 512;

[0072] The grippers 532 are arranged in pairs on the horizontal arm 531 and are slidably connected to the horizontal arm 531.

[0073] The retraction drive is connected to the gripper 532 and is used to drive the gripper 532 to slide.

[0074] During implementation, the pallet carrying the battery pack moves forward on the roller conveyor with the front end of the battery pack facing the direction of travel, entering the workstation where the flipping mechanism is located via the roller conveyor. Once in position, the pallet is driven to rotate, for example, 90°. At this point, the front end of the battery pack faces one side of the roller conveyor, and the pallet carrying the battery pack flows out of the workstation. This allows downstream operators located on the side of the roller conveyor to operate the electrical components at the front end of the battery pack, which is more ergonomic, reduces operator workload, and improves the overall efficiency of the production line.

[0075] Furthermore, after the battery pack rotates 90°, the lifting drive assembly 510 drives the flipping device 500 to descend, allowing the fork arm 530 to clamp both sides of the battery pack. Then, the lifting drive assembly 510 drives the flipping device 500 to rise, and the flipping device 500 flips the battery pack 180 degrees. Then, the flipping device 500 is driven to descend and place the battery pack bottom up on the pallet. The fork arm 530 rises, and the pallet carries the flipped battery pack out of the station. This allows downstream operators located on the side of the roller conveyor to operate the electrical components at the front and bottom of the battery pack, improving the overall efficiency of the line.

[0076] Secondly, this application also provides a battery production line, including a battery pack flipping mechanism as described above.

[0077] Those skilled in the art will clearly understand that, for the sake of convenience and brevity, the structure and implementation principle of the battery production line described above can be referred to the corresponding structure and implementation principle in the foregoing embodiments, and will not be repeated here.

[0078] In implementation, the battery production line provided in this application further includes a first transport line and a second transport line. The first transport line is connected to the input end of the flipping mechanism, and its width is adapted to the width of the battery pack. The second transport line is connected to the output end of the flipping mechanism, and its width is adapted to the length of the battery pack. The width of the second transport line is greater than that of the first transport line. That is, the first transport line can be regarded as the upstream roller conveyor of the workstation, where the battery packs on the pallet enter the workstation via the first transport line. The second transport line can be regarded as the downstream roller conveyor of the workstation, where the flipped battery packs flow out from the workstation to the second transport line, and are then transported to the downstream workstation by the second transport line.

[0079] The battery pack flipping mechanism provided in this application includes a base support 100; a rotating component 200 disposed on the base support 100; and a tray for supporting the battery pack. The rotating component 200 is connected to the tray and drives the tray to rotate the battery pack, with the rotation angle being 80 to 110 degrees. By rotating the battery pack so that its front end faces the side of the roller conveyor, it facilitates the operation of the electrical components at the front end of the battery pack by operators located on the side of the roller conveyor, which is more ergonomic, reduces the workload of operators, and improves the overall efficiency of the production line.
