By alternately stacking the bipolar plates and the membrane electrode assemblies layer by layer, the core part of the hydrogen fuel cell, namely the stack, is formed. The stack usually needs to be assembled by a stack stacking equipment. During the stack stacking process, affected by the uneven surface of the membrane electrode assembly (the thickness is larger in the middle part and smaller at both ends), when there are a small number (≤50 pieces) of membrane electrode assemblies stored in the membrane electrode frame, the membrane electrode assemblies are approximately horizontal in the frame as a whole, while when there are a large number (>50 pieces) of membrane electrode assemblies stored in the membrane electrode frame, the membrane electrode assemblies show a phenomenon of being high in the middle and bent at both sides in the frame.

[0036] The present utility model will be described in detail below with reference to the drawings and in combination with embodiments.
[0037] Embodiment 1
[0038] This embodiment relates to an adsorption device for stack of fuel cells, which can still adsorb the attachment to be adsorbed smoothly when the surface of the attachment to be adsorbed is uneven.
[0039] In terms of the overall structure, as Figure 1 shown, the adsorption device for stack of fuel cells in this embodiment includes a connecting seat 1 and an adsorption assembly arranged on the connecting seat 1. The adsorption assembly includes a first adsorbent 2 for adsorbing the middle part of the attachment to be adsorbed and a second adsorbent 3 for adsorbing the end part of the attachment to be adsorbed. Moreover, both the first adsorbent 2 and the second adsorbent 3 are arranged on the connecting seat 1 through adjusting members, and the adjusting members can adjust the relative distances between the first adsorbent 2, the second adsorbent 3 and the connecting seat 1.
[0040] At this time, in the above structure, by providing the first adsorbing member 2 and the second adsorbing member 3 on the connecting base 1, and enabling the first adsorbing member 2 and the second adsorbing member 3 to adsorb the middle part and the end part of the workpiece to be adsorbed respectively, and when the adjusting member expands and contracts, the relative distances between the first adsorbing member 2 and the second adsorbing member 3 and the connecting base 1 can be adjusted respectively. Thus, when the surface of the workpiece to be adsorbed is uneven, the workpiece to be adsorbed can still be smoothly adsorbed.
[0041] Moreover, when applied to the feeding of membrane electrodes, when the membrane electrodes in the membrane electrode frame are stored in large quantities and show a high middle part and bent ends, the membrane electrodes can still be smoothly adsorbed, thereby effectively solving the problems of frequent feeding of membrane electrodes and many stacking beats. Specifically, continue to refer to Figure 1 As shown, as an exemplary structure, in this embodiment, the first adsorbing member 2 is located in the middle of the connecting base 1, and the second adsorbing members 3 are respectively provided on two opposite sides of the first adsorbing member 2. At this time, the first adsorbing member 2 can better adsorb the middle part of the workpiece to be adsorbed, and the two second adsorbing members 3 on both sides can better adsorb the two end parts of the workpiece to be adsorbed, so as to further improve the adsorption effect of the workpiece to be adsorbed.
[0042] Next, in this embodiment, taking the workpiece to be adsorbed as a membrane electrode and a bipolar plate as an example, the adsorption device for stack assembly of the present embodiment will be described in detail.
[0043] First of all, it should be noted that the membrane electrode is mainly composed of a proton exchange membrane, a catalyst on the proton exchange membrane, a GDL, and a frame in structure. The membrane electrode is divided into a manifold area, a reaction area, and a gas distribution area according to its function. Among them, the thickness of the reaction area in the middle part of the membrane electrode is the largest, and the thickness of the manifold area at the end of the membrane electrode is the smallest. Therefore, when there are a large number (>50 pieces) of membrane electrodes in the membrane electrode frame, the membrane electrodes show a high middle part and bent ends in the frame.
[0044] In the adsorption device for stack assembly of the present embodiment, in terms of specific structure, the first adsorbing member 2 is used to adsorb the reaction area of the membrane electrode, and the two second adsorbing members 3 on both sides are used to adsorb the manifold area and the gas distribution area of the membrane electrode. The connecting base 1 can be specifically arranged on the manipulator 10, and the manipulator 10 is used to drive the adsorption device for stack assembly to move to adsorb the membrane electrode or the bipolar plate.
[0045] As a preferred embodiment, the first adsorbing member 2 of the present embodiment includes a Bernoulli suction cup, and the second adsorbing member 3 includes a negative pressure suction cup with a negative pressure cavity. A plurality of adsorption ports communicated with the negative pressure cavity are provided on the side of the negative pressure suction cup facing the workpiece to be adsorbed. In this way, the first adsorbing member 2 adopts positive pressure adsorption, and the second adsorbing member 3 adopts negative pressure adsorption, which can not only meet the smooth adsorption of the membrane electrode, but also meet the smooth adsorption of the bipolar plate, thus improving the versatility effect of the adsorption device.
[0046] In specific implementation, the Bernoulli suction cup specifically adopts an existing mature structure. During suction, a positive pressure is formed between the Bernoulli suction cup and the middle part of the membrane electrode to fix the middle part of the membrane electrode. The negative pressure suction cup can be connected to a vacuum generator, and the vacuum generator makes the negative pressure cavity in the negative pressure suction cup form a negative pressure environment, so as to suck the end part of the membrane electrode through a plurality of suction ports communicated with the negative pressure cavity.
[0047] To avoid the attached part to be sucked from being worn during the suction process, in this embodiment, a suction nozzle 31 is provided at the suction port. And preferably, the suction ports are arranged at intervals, and the suction nozzles 31 are also arranged at intervals. In this way, by using the flexibility of the suction nozzles 31, while ensuring the smooth suction of the membrane electrode, the membrane electrode can be effectively prevented from being worn during the suction process.
[0048] It should be noted that the attached part to be sucked in this embodiment can be not only a membrane electrode and a bipolar plate, but also a component with a slightly thicker middle part and a slightly thinner end part, or other components with an uneven surface. In addition, the adjusting part in this embodiment preferably adopts a spring, which has a simple structure, is easy to design and implement, and has good elastic force. It can be understood that in addition to using a spring, the adjusting part can also adopt an electric pull rod with a length that can be telescopically adjusted, so as to adjust the relative distance between the first attached part 2, the second attached part 3 and the connecting seat 1.
[0049] As a preferred implementation form, in this embodiment, a guiding structure is provided between the first attached part 2 and the connecting seat 1 and between the second attached part 3 and the connecting seat 1. The setting of this guiding structure is beneficial to guiding the telescopic deformation of the spring, and can effectively prevent the position of the first attached part 2 or the second attached part 3 from deviating greatly during the telescopic deformation of the spring.
[0050] For the convenience of distinction, in this embodiment, the adjusting part provided between the first attached part 2 and the connecting seat 1 is defined as the first elastic adjusting part 4, and the adjusting part provided between the second attached part 3 and the connecting seat 1 is defined as the second elastic adjusting part 5. The guiding structure provided between the first attached part 2 and the connecting seat 1 is defined as the first guiding structure, and the guiding structure provided between the second attached part 3 and the connecting seat 1 is defined as the second guiding structure. Among them, both the first elastic adjusting part 4 and the second elastic adjusting part 5 preferably adopt springs.
[0051] Specifically, as a preferred implementation manner, in this embodiment, refer to Figure 1 And in combination with Figure 2As shown, the first guiding structure includes a plurality of first guiding rods 6. One end of each first guiding rod 6 is connected to the first adsorbing member 2, and the other end slidably passes through the first guiding holes 11 in the connecting seat 1. In specific implementation, one ends of the plurality of first guiding rods 6 are fixedly connected to the first adsorbing member 2, the other ends of the plurality of first guiding rods 6 slidably pass through the first guiding holes 11 in the connecting seat 1, and a limiting nut 8 is screwed on this end portion. At this time, the plurality of first guiding rods 6 can be slidably arranged relative to the connecting seat 1 along the first guiding holes 11.
[0052] Furthermore, the plurality of first guiding rods 6 are arranged circumferentially around the first elastic adjusting member 4. Thus, through the arrangement of the plurality of first guiding rods 6, the first elastic adjusting member 4 can also be limited. At this time, both ends of the first elastic adjusting member 4 do not need to be respectively fixed to the first adsorbing member 2 and the connecting seat 1.
[0053] Continue to refer to Figure 1 and Figure 2 As shown, the second guiding structure of this embodiment includes a plurality of second guiding rods 7. One end of each second guiding rod 7 is connected to the second adsorbing member 3, and the other end slidably passes through the second guiding holes 12 in the connecting seat 1. In specific implementation, one ends of the plurality of second guiding rods 7 are fixedly connected to the second adsorbing member 3, the other ends of the plurality of second guiding rods 7 slidably pass through the second guiding holes 12 in the connecting seat 1, and a limiting nut 8 is also screwed on this end portion. At this time, the plurality of first guiding rods 6 can be slidably arranged relative to the connecting seat 1 along the first guiding holes 11. At this time, the plurality of second guiding rods 7 can be slidably arranged relative to the connecting seat 1 along the second guiding holes 12.
[0054] Similarly as a further aspect, the plurality of second guiding rods 7 are arranged circumferentially around the second elastic adjusting member 5. Thus, through the arrangement of the plurality of second guiding rods 7, the second elastic adjusting member 5 can also be limited. At this time, both ends of the second elastic adjusting member 5 do not need to be respectively fixed to the second adsorbing member 3 and the connecting seat 1.
[0055] It should be noted that in addition to arranging guiding structures between the first adsorbing member 2 and the connecting seat 1 and between the second adsorbing member 3 and the connecting seat 1, that is, arranging the first guiding structure and the second guiding structure, it can also be arranged to have only the first guiding structure between the first adsorbing member 2 and the connecting seat 1, or it can also be arranged to have only the second guiding structure between the second adsorbing member 3 and the connecting seat 1. This is also feasible.
[0056] In addition, it should also be noted that in addition to adopting the above-mentioned structure forms of the plurality of first guiding rods 6 and the plurality of second guiding rods 7 for the first guiding structure and the second guiding structure, it can also adopt guiding columns arranged on the first adsorbing member 2 or the second adsorbing member 3, and the adjusting member, i.e., the spring, is sleeved on the guiding column. Such an arrangement is also feasible.
[0057] For the adsorption device for stack of the fuel cell stack in this embodiment, when sucking the membrane electrode with the middle being high and both ends being low, by making the connecting seat 1 located above the membrane electrode and pressing the first adsorbing member 2 downward toward the direction where the membrane electrode is located, at this time, the first elastic adjusting member 4 is compressed, so that the second adsorbing members 3 on both sides approach the ends of the membrane electrode, thus ensuring that both the ends and the middle of the membrane electrode can be successfully sucked.
[0058] The adsorption device for stack of the fuel cell stack in this embodiment can be not affected by the uneven surface of the membrane electrode, and can still successfully adsorb the membrane electrode when the membrane electrode storage frame is full (more than 50 pieces), thereby reducing the feeding frequency of the membrane electrode, shortening the stacking cycle, and also being able to well adsorb the bipolar plate, and having high versatility.
[0059] Embodiment Two
[0060] This embodiment relates to a fuel cell stack stacking device, as Figure 3 shown, the fuel cell stack stacking device includes a manipulator 10 and the adsorption device for stack of the fuel cell stack in Embodiment One. Among them, the adsorption device for stack of the fuel cell stack is arranged on the manipulator 10. Specifically, the connecting seat 1 is fixed on the manipulator 10. Thus, the manipulator 10 is used to drive the connecting seat 1 to move, and drive the first adsorbing member 2 and the second adsorbing member 3 to suck the member to be adsorbed.
[0061] Continue to refer to Figure 3 shown, the fuel cell stack stacking device in this embodiment further includes a stacking platform 70 and a storage platform. Among them, a membrane electrode storage frame 20 and a bipolar plate storage frame 30 are arranged on the storage platform. The manipulator 10 is used to respectively grab the membrane electrodes in the membrane electrode storage frame and the bipolar plates in the bipolar plate storage frame 30 onto the stacking platform 70 for fuel cell stack stacking.
[0062] In this embodiment, preferably, a plurality of membrane electrode storage frames 20 and bipolar plate storage frames 30 are arranged at intervals. The plurality of membrane electrode storage frames 20 and the plurality of bipolar plate storage frames 30 are respectively arranged on both sides of the manipulator 10, which is beneficial for the manipulator 10 to suck the membrane electrodes and bipolar plates.
[0063] In addition, in this embodiment, an NG membrane electrode storage frame 40 and an NG bipolar plate storage frame 50 are further arranged on the storage platform. Among them, the NG membrane electrode storage frame 40 is used to store unqualified membrane electrodes, and the NG bipolar plate storage frame 50 is used to store unqualified bipolar plates.
[0064] In addition, as a preferred implementation manner, in this embodiment, a vision detection device 60 is arranged on one side of the stacking platform 70. The vision detection device 60 is used to perform appearance detection and position detection on the membrane electrodes or bipolar plates grabbed by the manipulator 10. Through the detection of the vision detection device 60, it is beneficial to ensure the quality of the fuel cell stack after stacking and prevent unqualified membrane electrodes or bipolar plates from flowing to the next process.
[0065] In specific implementation, the vision detection device 60 includes a CCD camera, which is used to detect the appearance and position of the membrane electrode and the bipolar plate grasped by the manipulator 10 respectively. When the appearance of the membrane electrode is unqualified, the manipulator 10 places the unqualified membrane electrode it grasps into the NG membrane electrode bin 40. When the appearance of the bipolar plate is unqualified, the manipulator 10 places the unqualified bipolar plate it grasps into the NG bipolar plate bin 50.
[0066] When the position of the membrane electrode or the bipolar plate sucked by the manipulator 10 is not at the preset position, the image collected by the CCD camera is fed back to the controller of the manipulator 10, and the controller controls the position of the manipulator 10 to be finely adjusted so that the sucked membrane electrode and bipolar plate are at the preset position, and then they are placed on the stacking platform 70. It should be noted here that the connection between the CCD camera and the controller of the manipulator 10 and the related control programs can all adopt existing mature technologies.
[0067] In addition, it should also be noted that in addition to detecting the appearance quality and position of the product, the vision detection device 60 can also detect the appearance quality of the product, or only detect the position of the product, which is also acceptable.
[0068] The stack stacking device of this embodiment can not only successfully adsorb the membrane electrode with an uneven surface, but also reduce the feeding frequency of the membrane electrode, reduce the stacking beat, and at the same time improve the automation degree and stacking efficiency.
[0069] The above are only the preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
