[0040] See also Figure 1 The fuel cell monomer assembly equipment 10 in the preferred embodiment of the utility model includes a first feeding device 100, a second feeding device 200, a third feeding device 300, a fourth feeding device 400, a conveying device 500, a film tearing device 600, a pressing device 700 and a turning device 800.

[0041] The first supply device 100 is capable of acquiring and supplying the membrane electrode.

[0042] Please also read Figure 2 Specifically in this embodiment, the first feeding device 100 includes a first transfer mechanism 110 , a thickness measuring mechanism 120 , a first appearance inspection mechanism 130 and a first material box 140 .

[0043] The first material box 140 is used to accommodate the membrane electrode. The first transfer mechanism 110 can obtain the membrane electrode from the first material box 140 and transfer the membrane electrode to the thickness measuring mechanism 120 and the first appearance inspection mechanism 130 in sequence. The thickness measuring mechanism 120 can detect the thickness of the membrane electrode, and the first appearance inspection mechanism 130 can detect the appearance of the membrane electrode to determine whether the membrane electrode has defects. Only membrane electrodes that pass both the thickness inspection and the appearance inspection can be used in subsequent processes; membrane electrodes that fail either the thickness inspection or the appearance inspection are identified as defective products and cannot be used in subsequent processes for the preparation of fuel cell monomers.

[0044] In addition, the first feeding device 100 generally further includes a first waste box 150 , and defective membrane electrode products can also be moved into the first waste box 150 by the first transfer mechanism 110 for storage.

[0045] It should be noted that in other embodiments, the first feeding device 100 may be omitted. In this case, the membrane electrode may be pre-tested for thickness and appearance, and directly fed to a position where it can be captured by the fuel cell monomer assembly device 10 .

[0046] Specifically in this embodiment, the first transfer mechanism 110 includes a first slide rail 111 and a first suction cup assembly 112 for sucking the membrane electrode. The first suction cup assembly 112 can be slidably installed on the first slide rail 111. The first material box 140, the thickness measuring mechanism 120 and the first appearance detection mechanism 130 are distributed on one side of the first slide rail 111 and are arranged in sequence along the extension direction of the first slide rail 111.

[0047] The first suction cup assembly 112 can first slide along the first slide rail 111 to the first material box 140, and suck the membrane electrode from the first material box 140. Then, the first suction cup assembly 112 passes through the thickness measuring mechanism 120 and the first appearance inspection mechanism 130 in sequence along the first slide rail 111, and the membrane electrode can be inspected for thickness and appearance in sequence. Moreover, the first suction cup assembly 112 reciprocates along a straight path during the process of transferring the membrane electrode, and its movement range is small and the trajectory is regular, so it is not easy to interfere with other components.

[0048] Please also read Figure 3 In this embodiment, the thickness measuring mechanism 120 includes a thickness measuring bracket 121, a contact sensor 122, a driving member 123 and a thickness measuring platform 124. The contact sensor 122 is mounted on the thickness measuring bracket 121, and the thickness measuring platform 124 is slidably mounted on the thickness measuring bracket 121 and can slide to the bottom of the contact sensor 122 or move out from the bottom of the contact sensor 122. The first transfer mechanism 110 can place the membrane electrode on the thickness measuring platform 124, and the driving member 123 can drive the contact sensor 122 to move to abut against the membrane electrode on the thickness measuring platform 124.

[0049] The thickness measuring bracket 121 plays a supporting role, the contact sensor 122 can realize contact thickness measurement, and the thickness measuring platform 124 is used to support the membrane electrode. Specifically, the thickness measuring platform 124 can be slidably installed on the thickness measuring bracket 121 through a guide rail. The driving member 123 can be a cylinder, which can drive the contact sensor 122 in a direction substantially perpendicular to the bearing surface of the thickness measuring platform 124, that is, Figure 3 Move in the up and down directions shown.

[0050] When the first transfer mechanism 110 places the membrane electrode on the thickness measuring platform 124, the thickness measuring platform 124 is first moved out from under the contact sensor 122. In this way, the thickness measuring bracket 121 and the contact sensor 122 can avoid the thickness measuring platform 124, thereby avoiding interference with the first transfer mechanism 110 and facilitating the first transfer mechanism 110 to place the membrane electrode on the thickness measuring platform 124. After the membrane electrode is placed on the thickness measuring platform 124, the thickness measuring platform 124 can slide to the bottom of the contact sensor 122. Then, the driving member 123 can drive the contact sensor 122 to descend until it abuts against the membrane electrode on the thickness measuring platform 124, thereby detecting the thickness of the membrane electrode.

[0051] In addition, the thickness measuring mechanism 120 further includes a limit block 125, which can move with the contact sensor 122. When the contact sensor 122 descends to a preset height, the limit block 125 can abut against the thickness measuring platform 124 to prevent the contact sensor 122 from continuing to move toward the thickness measuring platform 124, thereby protecting the contact sensor 122.

[0052] Please also read Figure 4 In this embodiment, the first appearance detection mechanism 130 includes a detection bracket 131, an upper visual component 132, a lower visual component 133 and a detection platform 134. The upper visual component 132 and the lower visual component 133 are arranged at intervals on the detection bracket 131, and a detection space is formed between the upper visual component 132 and the lower visual component 133. The detection platform 134 is slidably mounted on the detection bracket 131 and can be moved into or out of the detection space. The first transfer mechanism 110 can place the membrane electrode on the thickness measuring platform 124 located outside the detection space.

[0053] The detection bracket 131 plays a supporting role, and the detection platform 134 is used to carry the membrane electrode, and can be slidably installed on the detection bracket 131 through the guide rail. The structure of the upper visual component 132 and the lower visual component 133 can be the same. Specifically, the upper visual component 132 and the lower visual component 133 both include a camera component and a light source. The upper visual component 132 and the lower visual component 133 cooperate to perform visual inspection on both sides of the membrane electrode entering the detection space to determine whether there are defects in its appearance.

[0054] When the first transfer mechanism 110 places the membrane electrode on the detection platform 134, the detection platform 134 is first moved out of the detection space. In this way, the upper visual component 132 and the lower visual component 133 can avoid the detection platform 134, thereby avoiding interference with the first transfer mechanism 110. After the membrane electrode is placed on the detection platform 134, the detection platform 134 can slide into the detection space. In this way, the upper visual component 132 and the lower visual component 133 can perform appearance inspection on both sides of the membrane electrode carried on the detection platform 134.

[0055] In addition, in this embodiment, a lifting assembly (not shown) for supporting the membrane electrode is disposed inside the first material box 140. The lifting assembly can lift the membrane electrode one by one, and the lifting distance each time is equal to the thickness of the membrane electrode.

[0056] Specifically, each time the first transfer mechanism 110 takes out a membrane electrode from the first material box 140, the lifting assembly lifts once, so the height of the membrane electrode located at the top layer of the first material box 140 can always be maintained consistent. In this way, it can be ensured that the height of the membrane electrode grasped by the first transfer mechanism 110 is consistent each time, thereby reducing the adjustment time of the first transfer mechanism 110 and improving stability.

[0057] The second supply device 200 is capable of acquiring and supplying bipolar plates.

[0058] Please also read Figure 5 In this embodiment, the second feeding device 200 includes a second transfer mechanism 210 , a second appearance detection mechanism 220 , a second deflection correction platform 230 and a second material box 240 .

[0059] The second material box 240 is used to accommodate bipolar plates. The second transfer mechanism 210 can obtain the bipolar plates from the second material box 240 and transfer the bipolar plates to the second appearance inspection mechanism 220 and the second deflection correction station 230 in sequence. The second appearance inspection mechanism 220 can inspect the appearance of the bipolar plates to determine whether the bipolar plates have defects. The second deflection correction station 230 can position and correct the bipolar plates to ensure that the bipolar plates are in the required position and angle. After appearance inspection and deflection correction, the bipolar plates are carried on the second deflection correction station 230 and wait to be taken by subsequent processes. Bipolar plates that fail the appearance inspection are identified as defective products and cannot be used in subsequent processes for the preparation of fuel cell monomers.

[0060] The second feeding device 200 generally further includes a second waste box 250 , and defective bipolar plates can be moved into the second waste box 250 by the second transfer mechanism 210 for storage.

[0061] It should be noted that in other embodiments, the second feeding device 200 may be omitted. In this case, the bipolar plate may be pre-inspected for appearance and corrected, and directly fed to a position where it can be captured by the fuel cell monomer assembly device 10 .

[0062] The second transfer mechanism 210 and the second appearance inspection mechanism 220 can respectively adopt the same structure as the first transfer mechanism 110 and the first appearance inspection mechanism 130. Specifically in the present embodiment, the second transfer mechanism 210 includes a second suction cup assembly 211 for sucking the bipolar plate, and the second suction cup assembly 211 can be slidably mounted on the first slide rail 111. The second material box 240, the second appearance inspection mechanism 220 and the second deviation correction platform 230 are distributed on the other side of the first slide rail 111 facing away from the first material box 140, the thickness measuring mechanism 120 and the first appearance inspection mechanism 130, and are sequentially arranged at intervals along the extension direction of the first slide rail 111.

[0063] When providing the bipolar plate, the second suction cup assembly 211 can first slide along the first slide rail 111 to the second material box 240, and suck the bipolar plate from the second material box 240. Then, the second suction cup assembly 211 passes through the second appearance inspection mechanism 220 and the second deflection correction platform 230 in sequence along the first slide rail 111, and the bipolar plate can be inspected and corrected in sequence. The second suction cup assembly 211 reciprocates along a straight path during the transfer of the bipolar plate. Its movement range is small and the trajectory is regular, so it is not easy to interfere with other components.

[0064] Moreover, the second suction cup assembly 211 can share the first slide rail 111 with the first suction cup assembly 112, so the structure can be simplified and space can be saved.

[0065] The third feeding device 300 can obtain and provide the flow channel carbon paper.

[0066] Please also read Figure 6 In this embodiment, the third feeding device 300 includes a third transfer mechanism 310 , a third deviation correction platform 320 and a third material box 330 .

[0067] The third material box 330 is used to hold the flow channel carbon paper. The third transfer mechanism 310 can obtain the flow channel carbon paper from the third material box 330 and transfer the flow channel carbon paper to the third deflection correction station 320. The third deflection correction station 320 can position and correct the flow channel carbon paper to ensure that the flow channel carbon paper is at the required position and angle. After the deflection correction, the flow channel carbon paper is carried on the third deflection correction station 320 and waits to be taken by the subsequent process.

[0068] The third transfer mechanism 310 and the third deflection correction platform 320 may adopt the same structure as the second transfer mechanism 210 and the second deflection correction platform 230. In addition, the third feeding device 300 generally further includes a third waste box 340. The flow channel carbon paper carried on the third deflection correction platform 320 can also be inspected for appearance, and the flow channel carbon paper that fails the appearance inspection is moved by the third transfer mechanism 310 into the third waste box 340 for storage.

[0069] It should be noted that in other embodiments, the third feeding device 300 may be omitted. At this time, the flow channel carbon paper may be pre-tested for appearance and rectified, and directly fed to a position where it can be captured by the fuel cell monomer assembly device 10 .

[0070] Please refer again Figure 1 The fourth feeding device 400 can obtain and provide double-sided adhesive tape, and both sides of the double-sided adhesive tape are covered with backing films. Specifically in this embodiment, the fourth feeding device 400 includes a fourth deflection correction platform 410 and a fourth material box 420, and the fourth material box 420 is used to accommodate the double-sided adhesive tape.

[0071] The transport device 500 can obtain the double-sided adhesive tape from the fourth material box 420 and transfer the double-sided adhesive tape to the fourth deflection correction station 410. The fourth deflection correction station 410 can position and correct the double-sided adhesive tape to ensure that the double-sided adhesive tape is in the required position and angle. After the deflection correction, the double-sided adhesive tape is carried on the fourth deflection correction station 410 and waits to be taken by the subsequent process. In addition, the fourth feeding device 400 generally also includes a fourth waste box 430. The double-sided adhesive tape carried on the fourth deflection correction station 430 can also be inspected for appearance, and the double-sided adhesive tape that fails the appearance inspection is moved into the fourth waste box 430 by the transport device 500 for storage.

[0072] It should be noted that in other embodiments, the fourth feeding device 400 may be omitted. In this case, the double-sided tape may be pre-tested for appearance and rectified, and directly fed to a position where it can be captured by the fuel cell monomer assembly device 10 .

[0073] The press-fitting device 700 includes a press-fitting platform 710 and a pressing head mechanism 720. Among them, the transport device 500 can transport the membrane electrode, bipolar plate, flow channel carbon paper and double-sided tape to the press-fitting platform 710. Specifically, the transport device 500 can obtain the membrane electrode, bipolar plate, flow channel carbon paper and double-sided tape from the first appearance inspection mechanism 130, the second deflection correction station 230, the third deflection correction station 320 and the fourth deflection correction station 410, and transport them to the press-fitting platform 710.

[0074] Furthermore, the film tearing device 600 can tear off the back film of the double-sided adhesive facing away from the pressing platform 710 , and the pressing head mechanism 720 can perform a pressing operation on the material carried on the pressing platform 710 .

[0075] During the processing, the transport device 500 can first transport the double-sided tape to the press-mounting platform 710, and then the film-tearing device 600 can tear off the back film of the double-sided tape facing away from the press-mounting platform 710. Next, the transport device 500 transports the bipolar plate to the press-mounting platform 710 and stacks it with the double-sided tape, and then the pressing head mechanism 720 performs a pressing operation, so that the bipolar plate and the double-sided tape can be attached to obtain an intermediate component.

[0076] The flipping device 800 can flip the intermediate component so that the double-sided adhesive in the intermediate component faces upward. Specifically in this embodiment, the transport device 500 can first transfer the intermediate component from the press-fitting platform 710 to the flipping device 800, and the flipping mechanism 800 drives the intermediate component to complete a 180-degree flip. Then, the transport device 500 moves the flipped intermediate component back to the press-fitting platform 710. Obviously, in other embodiments, the flipping mechanism 800 can also directly flip the intermediate component carried on the press-fitting platform 710.

[0077] After the flipping device 800 flips the intermediate component, the film tearing device 600 tears off the back film on the other side of the double-sided tape. Then, the transport device 500 transports the flow channel carbon paper and the membrane electrode to the flipped intermediate component in turn. The pressing head mechanism 720 performs the pressing operation again, so that the flow channel carbon paper, the membrane electrode and the intermediate component can be bonded to obtain a fuel cell monomer. It can be seen that the above-mentioned fuel cell monomer assembly equipment 10 can realize the automated production of fuel cell monomers by only loading the membrane electrode, bipolar plate, flow channel carbon paper and double-sided tape to the preset position. Therefore, the production efficiency and product quality can be effectively improved, so large-scale mass production can be achieved.

[0078] Please also read Figure 7 and Figure 8 In this embodiment, the film tearing device 600 includes an unwinding assembly 610, a rewinding assembly 620, a driving motor 630 and a pressing roller 640. The unwinding assembly 610 and the rewinding assembly 620 can unwind and rewind the tape respectively under the drive of the driving motor 630, and the tape between the unwinding assembly 610 and the rewinding assembly 620 is wound around the pressing roller 640, and the pressing roller 640 can hold the tape against the surface of the double-sided tape carried on the pressing platform 710.

[0079] Specifically, the unwinding assembly 610, the winding assembly 620, the drive motor 630 and the pressure roller 640 can be installed together on the support plate 650. The surface of the adhesive tape facing away from the pressure roller 640 is sticky, so it can adhere to the backing film on the surface of the double-sided adhesive tape. The unwinding assembly 610 and the winding assembly 620 can be driven synchronously by the same drive motor 630, or they can be driven by different drive motors 630. During the winding process of the winding assembly 620, the adhesive tape can tear off the backing film of the double-sided adhesive tape and collect it into the winding assembly 620 along with the adhesive tape.

[0080] Obviously, in other embodiments, other methods may be used, such as using a suction cup to pull and tear off the backing film.

[0081] Please refer again Figure 1 In this embodiment, the press-fitting device 700 further includes a support rail 730 , and the press head mechanism 720 is slidably mounted on the support rail 730 , and can slide to the top of the press-fitting platform 710 or move out from the top of the press-fitting platform 710 .

[0082] When the pressing head mechanism 720 moves out from above the pressing platform 710, it can avoid the surface of the pressing platform 710. In this way, the pressing head mechanism 720 can avoid interfering with the transport device 500, and facilitate the transport device 500 to smoothly transport various materials to the surface of the pressing platform 710. When the pressing operation needs to be performed, the pressing head mechanism 720 slides along the support rail 730 to the top of the pressing platform 710.

[0083] Similarly, the film-tearing device 600 can also be installed on the support rail 730. When the double-sided adhesive film needs to be torn off, the film-tearing device 600 slides along the support rail 730 toward the pressing platform 710 until the pressing roller 640 can make the adhesive tape contact the surface of the double-sided adhesive. After the film-tearing is completed, the film-tearing device 600 slides along the support rail 730 toward the direction away from the pressing platform 710, thereby forming a clearance position on the surface of the pressing platform 710.

[0084] In this embodiment, the fuel cell monomer assembly equipment 10 further includes an airtightness detection device 900 , and the transport device 500 can transport the fuel cell monomer from the press-fitting platform 710 to the airtightness detection device 900 .

[0085] The airtightness detection device 900 can perform airtightness detection on the fuel cell monomer to determine whether its airtightness is qualified. The specific structure of the airtightness detection device 900 can be the same as the airtightness detection equipment in the prior art, so it will not be repeated here.

[0086] In addition, the fuel cell monomer assembly equipment 10 is also provided with a feed box 1100 and a finished product waste box 1200. The fuel cell monomers that pass the airtightness test can be transported by the transport device 500 to the feed box 1100 for storage, while the fuel cell monomers that fail the airtightness test can be transported by the transport device 500 to the finished product waste box 1200.

[0087] Furthermore, in this embodiment, the fuel cell monomer assembly equipment 10 also includes a transfer platform 1000 , and the transport device 500 can transport the fuel cell monomer from the press platform 710 to the transfer platform 1000 , and can transport the fuel cell monomer from the transfer platform 1000 to the airtightness detection device 900 .

[0088] In order to improve the accuracy of air tightness testing, when a fuel cell monomer fails the first test, it is generally necessary to conduct a second test. At this time, the next fuel cell monomer that has been assembled can be transported by the transport device 500 to the transfer platform for temporary storage. In this way, there will be no accumulation of fuel cell monomers on the press platform 710, and the fuel cell monomer assembly equipment 10 can assemble subsequent fuel cell monomers according to the original rhythm. After the second test of the previous fuel cell monomer is completed, the transport device 500 can transport the fuel cell monomer temporarily stored on the transfer platform 1000 to the air tightness testing device 900 for air tightness testing. In this way, the fuel cell monomer assembly equipment 10 can maintain the continuity of the production process.

[0089] In addition, in this embodiment, the transport device 500 includes a first transport mechanism 510 and a second transport mechanism 520 spaced apart along a first direction. The press-fit device 700 is located between the first transport mechanism 510 and the second transport mechanism 520, the first feeding device 100 and the second feeding device 200 are distributed on the side of the first transport mechanism 510 facing away from the second transport mechanism 520, and the fourth feeding device 400 is distributed on the side of the second transport mechanism 520 facing away from the first transport mechanism 510. The third feeding device 300 and the press-fit device 700 are spaced apart along a second direction perpendicular to the first direction.

[0090] by Figure 1 As shown in the example, the first direction refers to the left-right direction, and the second direction refers to the up-down direction. The first transport mechanism 510 and the second transport mechanism 520 have the same structure. The first transport mechanism 510 can transport the membrane electrode and the bipolar plate to the press-fitting platform 710, and the second transport mechanism 520 can transport the flow channel carbon paper and the double-sided tape to the press-fitting platform 710. In addition, the second transport mechanism 520 can also remove the assembled fuel cell monomer from the press-fitting platform 710.

[0091] It can be seen that the layout of the fuel cell monomer assembly equipment 10 is reasonable, and the running tracks of the first conveying mechanism 510 and the second conveying mechanism 520 do not overlap, so they are not easy to interfere with each other.

[0092] Furthermore, the first transport mechanism 510 and the second transport mechanism 520 transport different materials respectively, so they do not need to cross a large range during operation, and the moving distance can be shortened, thereby helping to further improve the production cycle.

[0093] In the above-mentioned fuel cell monomer assembly equipment 10, the transport device 500 can first transport the double-sided tape to the press-fitting platform 710, and then the film-tearing device 600 can tear off the back film of the double-sided tape on the side facing away from the press-fitting platform 710. Next, the transport device transports the bipolar plate to the press-fitting platform 710 and stacks it with the double-sided tape, and then the pressing head mechanism 720 performs the pressing operation, so that the bipolar plate and the double-sided tape can be bonded to obtain an intermediate component. After the flipping device 800 flips the intermediate component, the film-tearing device tears off the back film on the other side of the double-sided tape, and the transport device 500 then transports the flow channel carbon paper and the membrane electrode to the flipped intermediate component in turn. The pressing head mechanism 720 can perform the pressing operation, so that the flow channel carbon paper, the membrane electrode and the intermediate component can be bonded to obtain a fuel cell monomer. It can be seen that the above-mentioned fuel cell monomer assembly equipment 10 only needs to load the membrane electrode, bipolar plate, flow channel carbon paper and double-sided tape to the preset position, and the fuel cell monomer assembly equipment 10 can realize the automated production of fuel cell monomers.

[0094] The technical features of the above-described embodiments may be arbitrarily combined. To make the description concise, not all possible combinations of the technical features in the above-described embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0095] The above-mentioned embodiments only express several implementation methods of the utility model, and the description is relatively specific and detailed, but it cannot be understood as limiting the scope of the utility model patent. It should be pointed out that for ordinary technicians in this field, several modifications and improvements can be made without departing from the concept of the utility model, which all belong to the protection scope of the utility model. Therefore, the protection scope of the utility model patent shall be based on the attached claims.
