In addition, the terms "first" and "second" are only used to distinguish in the description and have no special meaning.

[0039] like Figure 1-5 As shown, the utility model provides a loading device, which includes a support seat 1, a lifting drive assembly 2 and a rotating drive assembly 3. At least two silos 4 are arranged on the support seat 1 at intervals. The rotating drive assembly 3 can drive the support seat 1 to rotate around a fixed axis so that any silo 4 can rotate to the expected work station; a pallet 5 is provided in the silo 4, and the pallet 5 is used to support materials; the output end of the lifting drive assembly 2 can pass through the support seat 1 and the bottom plate 41 of the silo 4 to connect with the pallet 5; when the output end of the lifting drive assembly 2 is connected with the pallet 5, the lifting drive assembly 2 can drive the pallet 5 to rise and fall along the height direction of the silo 4.

[0040] When the feeding device is working, the rotary drive assembly 3 is first controlled to drive one of the silos 4 filled with materials to rotate around the fixed axis to the expected work position, and then the output end of the lifting drive assembly 2 is controlled to move along the height direction of the silo 4 and pass through the support seat 1 and the bottom plate 41 to connect with the support plate 5. When the output end of the lifting drive assembly 2 is connected with the support plate 5, the output end of the lifting drive assembly 2 is continued to be controlled to rise along the height direction of the silo 4 until the uppermost layer of materials on the support plate 5 is lifted to the expected height position to facilitate the handling of materials; when the uppermost layer of materials on the support plate 5 is removed, the output end of the lifting drive assembly 2 is continued to be controlled to move along the height direction of the silo 4. The lifting drive assembly 2 is controlled to rise in the height direction, and the uppermost material on the pallet 5 is lifted to the expected height position until all the materials on the pallet 5 are removed; when all the materials on the pallet 5 are removed, the output end of the lifting drive assembly 2 is controlled to drive the pallet 5 to descend along the height direction of the silo 4, and when the pallet 5 is driven to descend to the lowest position, the output end of the lifting drive assembly 2 is controlled to be away from the support seat 1; in this process, materials are loaded on the remaining pallet 5 without materials; when the output end of the lifting drive assembly 2 is away from the support seat 1, the rotary drive assembly 3 is controlled to drive another silo 4 filled with materials to rotate around the fixed axis to the expected position. To achieve continuous loading.

[0041] By arranging a support plate 5 in the silo 4, the support plate 5 supports the material, and the lifting drive assembly 2 drives the support plate 5 to rise and fall along the height direction of the silo 4 to lift the material, so that the loading device can be applied to different types of materials, effectively improving the versatility of the loading device, and can also effectively avoid the risk of damaging the material during the lifting process of the lifting drive assembly 2, and can effectively improve the stability of driving the material to rise and fall. By setting the output end of the lifting drive assembly 2 to be connected to the support plate 5 through the support seat 1 and the bottom plate 41, when the output end of the lifting drive assembly 2 is connected to the support plate 5, the lifting drive assembly 2 drives the support plate 5 to rise and fall along the height direction of the silo 4, so that the lifting accuracy of driving the material to rise and fall along the height direction of the silo 4 can be effectively improved. Secondly, the risk of the support plate 5 tilting or even detaching from the output end of the lifting drive assembly 2 during the lifting process can be reduced, thereby further improving the stability of driving the material to rise and fall. It can be understood that, especially for the situation where the support plate 5 is affected by external vibration or the material is unevenly distributed on the support plate 5, the lifting accuracy and stability of driving the material to rise and fall can be effectively improved.

[0042] In this embodiment, the support plate 5 is used to support the bipolar plate. This effectively avoids damage to the bipolar plate during the lifting process, and effectively improves the lifting accuracy and stability of the bipolar plate. It is understandable that the support plate 5 can also be used to support other types of materials. When the top bipolar plate on the support plate 5 is lifted to the expected height, the top bipolar plate is moved away by the robotic arm.

[0043] In this embodiment, if Figure 1-5 As shown, two silos 4 are provided on the support seat 1 for example. It can be understood that when the feeding device is working, one silo 4 is at the expected position and the other silo 4 is at the waiting position, so that continuous feeding can be achieved.

[0044] The loading device further includes a position sensor, which is used to monitor the distribution position of the pallet 5 along the height direction of the silo 4. Specifically, when the position sensor detects that the pallet 5 is lifted to the point where the material on the uppermost layer of the pallet 5 reaches the expected height position, the lifting drive assembly 2 is controlled to stop lifting the pallet 5 to facilitate the transportation of the material on the uppermost layer of the pallet 5 at the expected height position; when the material on the uppermost layer of the pallet 5 is removed, the lifting drive assembly 2 is controlled to continue lifting the pallet 5 to make the material on the uppermost layer of the pallet 5 reach the expected height position until all the material on the pallet 5 is removed.

[0045] Among them, Figure 1 , Figure 3 and Figure 4 As shown, one of the output end of the lifting drive assembly 2 and the bottom of the support plate 5 is provided with a first permanent magnet 61, and the other is provided with a second permanent magnet or a magnetic body 62, and the first permanent magnet 61 is used to be magnetically connected with the second permanent magnet or the magnetic body 62. Specifically, when the output end of the lifting drive assembly 2 is controlled to move along the height direction of the silo 4 and pass through the support seat 1 to contact the support plate 5, the output end of the lifting drive assembly 2 is directly connected with the support plate 5 by magnetic attraction. The connection method is simple and fast, and can improve the lifting accuracy and stability of the material lifting; when the output end of the lifting drive assembly 2 drives the support plate 5 to descend along the height direction of the silo 4, and the support plate 5 is driven to descend to the lowest position, the driving force of the lifting drive assembly 2 pulls the output end of the lifting drive assembly 2 away from the support plate 5, so as to realize that the output end of the lifting drive assembly 2 is directly separated from the support plate 5.

[0046] Specifically, the output end of the lifting drive assembly 2 is provided with a first permanent magnet 61, and the bottom of the support plate 5 is provided with a second permanent magnet or a magnetic body 62, and the first permanent magnet 61 is used to be magnetically connected to the second permanent magnet or the magnetic body 62. As an alternative, the output end of the lifting drive assembly 2 is provided with a second permanent magnet or a magnetic body 62, and the bottom of the support plate 5 is provided with a first permanent magnet 61, and the first permanent magnet 61 is used to be magnetically connected to the second permanent magnet or the magnetic body 62.

[0047] In this embodiment, if Figure 1 , Figure 3 and Figure 4As shown, the output end of the lifting drive assembly 2 is provided with a first permanent magnet 61, and the bottom of the support plate 5 is provided with a magnetic body 62, and the first permanent magnet 61 is used to be magnetically connected with the magnetic body 62. Further, the magnetic body 62 is a counterweight. It can increase the weight of the support plate 5. When the output end of the lifting drive assembly 2 is separated from the support plate 5, the gravity of the counterweight can ensure that the support plate 5 is well distributed at the bottom of the silo 4.

[0048] Alternatively, if Figure 1-4 As shown, the bottom plate 41 is provided with a guide structure 7, which is used to guide the support plate 5 to rise and fall along the height direction of the silo 4. It can further improve the stability of driving the material to rise and fall, and avoid the risk of the support plate 5 tilting or even detaching from the output end of the lifting drive assembly 2 during the lifting process.

[0049] Specifically, Figure 1-4 As shown, the guide structure 7 includes a guide column 71, which is fixedly arranged on the bottom plate 41, and the support plate 5 is slidably connected to the guide column 71 along the height direction of the silo 4, so as to guide the support plate 5 to rise and fall along the height direction of the silo 4.

[0050] Furthermore, if Figure 1 , Figure 3 and Figure 4 As shown, the guide structure 7 further includes a linear bearing 72, and the support plate 5 is slidably connected to the guide column 71 through the linear bearing 72. The smoothness of guiding the support plate 5 to rise and fall along the height direction of the silo 4 can be improved.

[0051] Furthermore, if Figure 1-4 As shown, there are multiple guide structures 7, and the multiple guide structures 7 are spaced apart along the circumference of the silo 4. It can be understood that each silo 4 is provided with multiple guide structures 7. This can further improve the stability of driving the material to be lifted, and also make the support plate 5 only lift along the height direction of the silo 4.

[0052] Preferably, a limit block is provided at the free end of the guide column 71 , and the support plate 5 can abut against the limit block along the height direction of the silo 4 , so as to limit the lifting range of the support plate 5 along the height direction of the silo 4 and prevent the support plate 5 from detaching from the guide column 71 .

[0053] Among them, Figure 1-5 As shown, the silo 4 also includes a plurality of stoppers 42 fixedly arranged on the bottom plate 41, and the plurality of stoppers 42 are arranged one by one corresponding to the plurality of corners of the pallet 5, and the stoppers 42 are distributed at the periphery of the corners of the pallet 5. It can be understood that the bottom plate 41 and the plurality of stoppers 42 are arranged to form the silo 4. The stoppers 42 are arranged to be distributed at the periphery of the corners of the pallet 5, and the distribution positions of the pallet 5 and the materials can also be limited by the plurality of stoppers 42. It is preferred that the stoppers 42 and the pallet 5 have clearance fit. This ensures the smoothness of the lifting and lowering of the pallet 5 along the height direction of the silo 4.

[0054] Specifically, in this embodiment, Figure 1-5 As shown, the support plate 5 is roughly rectangular. The limiting member 42 is an angle iron. There are four limiting members 42, which are distributed on the outer periphery of the four corners of the support plate 5 in a one-to-one correspondence.

[0055] Specifically, the bottom plate 41 is integrally formed on the support base 1 . Alternatively, the bottom plate 41 is fixedly disposed on the support base 1 .

[0056] Further, when the bottom plate 41 is integrally formed with the support seat 1, the support seat 1 is provided with a first through hole penetrating along the height direction of the silo 4, and the output end of the lifting drive assembly 2 can pass through the first through hole to connect with the support plate 5. When the bottom plate 41 is fixedly arranged on the support seat 1, the support seat 1 is provided with a second through hole 11 penetrating along the height direction of the silo 4, the bottom plate 41 is provided with a third through hole 411 communicating with the second through hole 11, and the output end of the lifting drive assembly 2 can pass through the second through hole 11 and the third through hole 411 to connect with the support plate 5. In this way, the output end of the lifting drive assembly 2 can pass through the support seat 1 and the bottom plate 41 to connect with the support plate 5.

[0057] In this embodiment, if Figure 1 , Figure 2 and Figure 4 As shown, the bottom plate 41 is fixedly arranged on the support base 1. The support base 1 is provided with a second through hole 11 that passes through the height direction of the silo 4, and the bottom plate 41 is provided with a third through hole 411 that communicates with the second through hole 11. The output end of the lifting drive assembly 2 can pass through the second through hole 11 and the third through hole 411 to connect with the support plate 5.

[0058] Alternatively, if Figure 2 and Figure 4 As shown, the silo 4 also includes a pad 43 distributed in the silo 4, and the pad 43 is detachably connected to the bottom plate 41. The pad 43 is used to adjust the lowest position to which the pallet 5 can be lowered along the height direction of the silo 4. Specifically, by increasing or decreasing the number of pads 43 and / or adjusting the size of the pad 43, the lowest position to which the pallet 5 can be lowered in the silo 4 can be adjusted. Specifically, when the pad 43 is provided on the bottom plate 41, the position where the pallet 5 contacts the pad 43 is the lowest position to which the pallet 5 can be lowered. The pad 43 provides a supporting force to the pallet 5 so that the driving force of the lifting drive assembly 2 can pull the output end of the lifting drive assembly 2 away from the pallet 5. When the pad 43 is not provided on the bottom plate 41, the position where the pallet 5 contacts the bottom plate 41 is the lowest position to which the pallet 5 can be lowered. The bottom plate 41 provides a supporting force to the pallet 5 so that the driving force of the lifting drive assembly 2 can pull the output end of the lifting drive assembly 2 away from the pallet 5.

[0059] Among them, Figure 1-4As shown, the lifting drive assembly 2 includes a lifting drive member, the housing of which is fixedly arranged on the mounting plate 9, and one of the output end of the lifting drive member and the bottom of the support plate 5 is provided with a first permanent magnet 61, and the other is provided with a second permanent magnet or a magnetic body 62. Specifically, in this embodiment, the lifting drive member is a linear motor. As an alternative, the lifting drive member can also adopt an electric push rod or a cylinder, etc. It can drive the support plate 5 to rise and fall along the height direction of the silo 4.

[0060] Among them, Figure 1 , Figure 3 and Figure 4 As shown, the rotary drive assembly 3 includes a rotary drive member 31 and a turntable 32. The turntable 32 is fixedly arranged at the bottom of the support base 1. The rotary drive member 31 can drive the turntable 32 to rotate around a fixed axis. The rotary drive member 31 drives the turntable 32 to rotate around the fixed axis, thereby driving the support base 1 to rotate around the fixed axis, so that each bin 4 can be rotated to the expected position.

[0061] Specifically, Figure 1 , Figure 3 and Figure 4 As shown, the housing of the rotary drive member 31 is fixedly arranged on the mounting plate 9. The rotary drive assembly 3 also includes a transmission gear, and a toothed portion is arranged on the outer periphery of the turntable 32. The transmission gear meshes with the toothed portion and is transmission-connected with the output shaft of the rotary drive member 31. This enables the turntable 32 to rotate around a fixed axis. In this embodiment, the rotary drive member 31 is a motor.

[0062] Preferably, the central axis of the turntable 32 is colinear with the fixed axis, and at least two bins 4 are distributed on the same circumference with the fixed axis as the central axis. This arrangement allows each bin 4 to be rotated to the desired workstation directly above the lifting drive assembly 2, making it convenient to set the wiring hole 8 in the central area of ​​the support seat 1, and effectively reducing the volume, weight and occupied space of the loading device. It can be understood that the desired workstation is directly above the lifting drive assembly 2.

[0063] Preferably, if Figure 4 and Figure 5 As shown, the feeding device further includes a wiring hole 8, which passes through the turntable 32 and the support seat 1. It can be understood that the wiring hole 8 is roughly located in the central area of ​​the support seat 1, which is convenient for the wiring of the position sensors corresponding to each silo 4. Further preferably, the central axis of the wiring hole 8 is colinear with the fixed axis.

[0064] The utility model also provides a fuel cell stack assembly device, including the above-mentioned feeding device. By adopting the above-mentioned fuel cell stack assembly device, the assembly efficiency of the fuel cell stack can be effectively improved, and the defective rate of the assembled fuel cell stack can be effectively reduced.
