[0039] See Figure 1 , Figure 2 and Figure 6 This diagram illustrates a schematic structural diagram of a fuel cell stack assembly apparatus according to an embodiment of this application. The fuel cell stack assembly apparatus includes a fuel cell stack loading mechanism 100, a bracket loading mechanism 200, an assembly mechanism 300, and a transport mechanism 400. The fuel cell stack loading mechanism 100 includes a first support frame 110 and a first conveying component 120. The first support frame 110 is used to place the fuel cell stack 10, and the first conveying component 120 is disposed on the first support frame 110 and used to move the fuel cell stack 10. The bracket loading mechanism 200 includes a second support frame 210, which is used to place the bracket 20. The assembly mechanism 300 includes a support plate 310 and a second conveying component 320. The support plate 310 is mounted on the second conveying component 320 and is used to support the fuel cell stack 10 and the bracket 20. The second conveying component 320 is used to move the support plate 310. The handling mechanism 400 includes a drive module 410 and a clamping assembly 420. The clamping assembly 420 is connected to the drive module 410 in a transmission manner. The movement range of the clamping assembly 420 includes the fuel cell stack loading mechanism 100, the bracket loading mechanism 200, and the assembly mechanism 300. The clamping assembly 420 is used to clamp or release the fuel cell stack 10 and to clamp or release the bracket 20.

[0040] In an exemplary embodiment, the assembly mechanism 300 includes a loading position, a processing position, and a unloading position. The loading position is used to transport the fuel cell stack 10 and the bracket 20 onto the support plate 310. The processing position is used to assemble the fuel cell stack 10 onto the bracket 20. The unloading position is used to unload the assembled fuel cell stack 10 and the bracket 20. The support plate 310 moves between the loading position, the processing position, and the unloading position by being driven by the second conveying component 320.

[0041] The fuel cell stack assembly device described in this application embodiment allows multiple fuel cell stacks 10 produced on the production line to be transported to a first support frame 110 for storage via a transport mechanism 400, and a tray 20 produced on the production line to be transported to a second support frame 210 for storage via the transport mechanism 400. The first conveying component 120 can move the fuel cell stacks 10 on the first support frame 110, making the storage space of the first support frame 110 more efficient.

[0042] When the fuel cell stack 10 and the bracket 20 are assembled, the second conveying component 320 moves the support plate 310 to the loading position, and then the drive module 410 and the clamping component 420 transfer the bracket 20 to the support plate 310 of the assembly mechanism 300. The clamping component 420 and the drive module 410 clamp the multiple fuel cell stacks 10 and place them in the mounting area of ​​the bracket 20. Then the second conveying component 320 moves the support plate 310 with the fuel cell stacks 10 and the bracket 20 placed thereto to the processing position for assembly. After the assembly is completed, the second conveying component 320 unloads the assembled fuel cell stacks and brackets.

[0043] The fuel cell stack assembly device described in this application uses a drive module 410 and a clamping assembly 420 to automatically feed the fuel cell stack 10 and the bracket 20, enabling the fuel cell stack 10 to be quickly and accurately placed in the installation area of ​​the bracket 20, reducing manual operation steps, and has the advantages of high production efficiency and low cost.

[0044] In one exemplary embodiment, the fuel cell stack loading mechanism 100 includes two units, the bracket loading mechanism 200 includes one unit, and the assembly mechanism 300 includes two units. The fuel cell stack assembly device is provided with a loading area, the two fuel cell stack loading mechanisms 100 and the bracket loading mechanism 200 are arranged adjacent to each other in the loading area, and the two assembly mechanisms 300 are respectively arranged on both sides of the loading area.

[0045] In some embodiments, the assembly mechanism 300 further includes a vision sensor disposed on one side of the support plate 310, corresponding to the position where the bracket 20 connects to the fuel cell stack 10. By disposing of the vision sensor on one side of the support plate 310, the vision sensor can acquire an image of the position of the fuel cell stack 10 in the mounting area of ​​the bracket 20 when it is placed. Based on this image, it can determine whether the fuel cell stack 10 is accurately placed in the mounting area of ​​the bracket 20, ensuring accurate connection between the fuel cell stack 10 and the bracket 20 without manual adjustment, thereby improving the assembly efficiency of the fuel cell stack 10 and reducing labor costs.

[0046] In one exemplary embodiment, a plurality of vision sensors are included, and each vision sensor is respectively set to correspond one-to-one with the position of the plurality of fuel cell stack 10 connecting brackets 20, thereby detecting the installation position of each fuel cell stack 10.

[0047] In one exemplary embodiment, the vision sensor is a CCD camera. CCD cameras have the advantages of high precision and good stability, and are suitable for detecting the position of the fuel cell stack 10 assembled on the bracket 20 in the fuel cell stack assembly device of this embodiment, thereby improving assembly efficiency.

[0048] In an optional embodiment, the handling mechanism 400 further includes an automated guided vehicle (AGV) for moving the fuel cell stack 10 to the loading position of the fuel cell stack loading mechanism 100 and the tray 20 to the loading position of the tray loading mechanism 200. Specifically, multiple AAVs are included. After the fuel cell stack 10 production line finishes producing the fuel cell stack 10, the AAVs transport the fuel cell stack 10 to the fuel cell stack loading mechanism 100. After the tray 20 production line finishes producing the tray 20, the AAVs transport the tray 20 to one side of the tray loading mechanism 200, and then transfer it to the tray loading mechanism 200 via the drive module 410 and the clamping assembly 420. This automates the handling of the fuel cell stack 10 and the tray 20, providing a high degree of automation.

[0049] In one exemplary embodiment, the Automated Guided Vehicle (AVG) can employ various advanced guidance methods such as laser guidance, visual guidance, magnetic strip guidance, and QR code guidance. It can perceive and identify its surrounding environment through onboard equipment to determine its own position and plan its travel path. The AVG does not rely on fixed tracks and possesses autonomous navigation, obstacle avoidance, and scheduling functions. It can enable collaborative operation of multiple vehicles, freely traverse relatively complex environments without fixed tracks, bypass obstacles, and flexibly change its travel route according to task requirements and actual site conditions, offering a high degree of flexibility.

[0050] In an optional embodiment, such as Figure 1As shown, the fuel cell stack assembly device also includes a docking mechanism 500, which is located at the unloading position of the assembly mechanism 300. The docking mechanism 500 includes a third support frame 510 and a third conveying component 520. The third conveying component 520 is mounted on the third support frame 510 and is used to transfer the assembled fuel cell stack 10 and the bracket 20 from the assembly mechanism 300 to the automated guided vehicle. By setting the docking mechanism 500 at the unloading position of the assembly mechanism 300, after the fuel cell stack 10 and the bracket 20 are assembled, the third conveying component 520 transfers the assembled fuel cell stack 10 and the bracket 20 from the assembly mechanism 300 to the automated guided vehicle, thereby completing the unloading of the assembled fuel cell stack 10 without manual operation, thus improving the automation level of the fuel cell stack assembly device.

[0051] Combination Figure 3 This diagram illustrates the structure of a fuel cell stack loading mechanism 100 in an embodiment of this application. In an optional embodiment, the first conveying component 120 includes a first driving unit 121 and a plurality of first rollers 122. The plurality of first rollers 122 are rotatably mounted on a first support frame 110. The first driving unit 121 is mounted on the first support frame 110, and the power output end of the first driving unit 121 is connected to the first rollers 122. Specifically, the first conveying component 120 is arranged along the Y-axis direction, and the first rollers 122 are spaced apart along the extension direction of the first support frame 110. By arranging the plurality of first rollers 122 on the first support frame 110, when the fuel cell stack 10 is placed on the first support frame 110, the first driving unit 121 drives the first rollers 122 to rotate, thereby moving the fuel cell stack 10 on the first support frame 110, adjusting the position of the fuel cell stack 10 on the first support frame 110, and optimizing the placement space of the fuel cell stack loading mechanism 100.

[0052] It should be noted that, as Figure 1 and Figure 3 As shown in the embodiments of this application, the X-axis and Y-axis directions are set perpendicular to each other in the horizontal plane, and the Z-axis direction is set perpendicular to the horizontal plane.

[0053] In one exemplary embodiment, the first drive unit 121 is a motor.

[0054] In an optional embodiment, such as Figure 6As shown, the second conveying assembly 320 includes a first guide rail 321, a second drive unit, a second roller 323, and a third drive unit. A support plate 310 is movably mounted on the first guide rail 321. The second drive unit is mounted on the first guide rail 321, and its power output end is connected to the second roller 323. The second roller 323 is movably mounted on the support plate 310. The third drive unit is mounted on the support plate 310, and its power output end is connected to the second roller 323. Specifically, the first guide rail 321 is arranged along the X-axis, and the second rollers 323 are spaced apart along the Y-axis. By setting the first guide rail 321, the second drive unit drives the assembled fuel cell stack 10 on the support plate 310 to move in the X-axis direction, thereby switching the support plate 310 of the assembly mechanism 300 between the loading position, processing position, and unloading position, improving the assembly efficiency of the fuel cell stack assembly device. Furthermore, a second roller 323 and a third drive unit are provided on the support plate 310. When the fuel cell stack 10 and the bracket 20 are assembled, the fuel cell stack 10 is transferred to the docking mechanism 500 through the second roller 323 and the third drive unit to achieve automated unloading and improve production efficiency.

[0055] In one exemplary embodiment, the second drive unit and the third drive unit are motors.

[0056] In an optional embodiment, such as Figure 4 and Figure 5 As shown, the drive module 410 includes an X-axis guide rail 411, a Y-axis guide rail 412, a Z-axis guide rail 413, an X-axis drive unit 414, a Y-axis drive unit 415, and a Z-axis drive unit 416. The X-axis guide rail 411 is disposed on the top of the fuel cell stack assembly along the X-axis direction. The X-axis drive unit 414 is mounted on the X-axis guide rail 411. The Y-axis guide rail 412 is movably disposed on the X-axis guide rail 411 along the Y-axis direction. The power output of the X-axis drive unit 414... The Y-axis drive unit 415 is mounted on the Y-axis guide rail 412, and the Z-axis guide rail 413 is movably mounted on the Y-axis guide rail 412 along the Z-axis direction. The power output end of the Y-axis drive unit 415 is connected to the Z-axis guide rail 413. The clamping assembly 420 is movably mounted on the Z-axis guide rail 413, and the Z-axis drive unit 416 is mounted on the Z-axis guide rail 413. The power output end of the Z-axis drive unit 416 is connected to the clamping assembly 420. The drive module 410 is driven by the X-axis guide rail 411, Y-axis guide rail 412 and Z-axis guide rail 413, and by the X-axis drive unit 414, Y-axis drive unit 415 and Z-axis drive unit 416, thereby controlling the clamping assembly 420 to move on the X-axis, Y-axis and Z-axis. Thus, the clamping assembly 420 clamps the fuel cell stack 10 and moves between the fuel cell stack loading mechanism 100 and the assembly mechanism 300, and clamps the bracket 20 and moves between the bracket loading mechanism 200 and the assembly mechanism 300, which has the advantage of high automation.

[0057] Furthermore, such as Figure 2 and Figure 3 As shown, the clamping assembly 420 includes a gripper 421 and a gripper drive unit 422, with the power output end of the gripper drive unit 422 connected to the gripper 421. By driving the gripper 421 to clamp or release via the gripper drive unit 422, the fuel cell stack 10 or the bracket 20 can be clamped and moved, improving the automation level of the fuel cell stack assembly device and reducing labor costs.

[0058] In an exemplary embodiment, the X-axis drive unit 414, the Y-axis drive unit 415, and the Z-axis drive unit 416 are all servo motors.

[0059] In an exemplary embodiment, the gripper drive unit 422 further includes a rotary motor and a drive motor. The rotary motor is used to drive the gripper 421 to rotate, and the drive motor is used to drive the gripper 421 to clamp or release.

[0060] In an optional embodiment, such as Figure 1 As shown, the third conveying assembly 520 includes a fourth drive unit and multiple third rollers. The multiple third rollers are rotatably mounted on the third support frame 510, and the power output of the fourth drive unit is connected to the third rollers. Specifically, the third conveying assembly 520 is arranged along the Y-axis direction. By mounting the multiple third rollers on the third support frame 510, when the battery stack 10 with the assembled bracket 20 is transferred from the assembly mechanism 300 to the third support frame 510, the fourth drive unit drives the third rollers to rotate, thereby moving the battery stack 10 on the third rollers, thus transferring the battery stack 10 from the assembly mechanism 300 to the automatic guide vehicle, achieving automated unloading.

[0061] In one exemplary embodiment, the fourth drive unit is a motor.

[0062] In an optional embodiment, such as Figure 2 As shown, the tray loading mechanism 200 also includes a sensing component 220, which includes a second bracket 221 and multiple position sensors 222. The second bracket 221 is disposed on one side of the second support frame 210, and the position sensors 222 are mounted on the second bracket 221. By setting the sensing component 220 on one side of the second support frame 210, the position sensors 222 can detect the loading trays 20, thereby obtaining whether the number and position of the trays 20 in the tray loading mechanism 200 are correct, and improving the automation level of the fuel cell stack assembly device.

[0063] In one exemplary embodiment, the position sensor 222 is an electro-optic sensor, which can realize the presence detection of the bracket 20 with low cost and high reliability, thereby improving the automation and stability of the fuel cell stack assembly device.

[0064] In an optional embodiment, the assembly mechanism 300 further includes a clamping assembly and a welding assembly.

The robotic arm is disposed at the processing station of the assembly mechanism 300, and the welding head is connected to the end of the robotic arm. In the assembly mechanism 300, the fuel cell stack 10 can be clamped and fixed on the bracket 20 by the clamping assembly, and then the fuel cell stack 10 and the bracket 20 can be welded together by the welding assembly, thereby automating the assembly of the fuel cell stack 10 and the bracket 20, which has the advantage of a high degree of automation.

[0065] In one exemplary embodiment, the clamping drive unit is a cylinder drive device.

[0066] In other embodiments, workers manually process the fuel cell stack 10 and the bracket 20 at the processing position of the assembly mechanism 300.
