The bipolar plate sealing ring paving device 100 will be described in detail below.

[0050] Please refer to Figure 1 and Figure 2 , Figure 1 The schematic diagram of the bipolar plate sealing ring paving device 100 and the paving of the sealing ring and the bipolar plate 200 provided in this embodiment is as follows: Figure 2 The schematic diagram of the structure of the bipolar plate sealing ring paving device 100 provided in this embodiment is combined with Figure 1 and Figure 2 The bipolar plate sealing ring paving equipment 100 is used to bond the first sealing ring 300 to the lower side of the bipolar plate 200, and at the same time bond the second sealing ring 400 to the upper side of the bipolar plate 200. The bipolar plate sealing ring paving equipment 100 includes a paving platform 10, a lower paving module 20, a first driving device 30 and an upper paving module 40. It can be understood that when paving, the first sealing ring 300 is installed on the lower paving module 20, and the second sealing ring 400 is installed on the upper paving module 40. The first driving device 30 drives the upper paving module 40 to move toward the lower paving module 20, so that the upper paving module 40 and the lower paving module 20 simultaneously press the two sides of the bipolar plate 200, thereby realizing the simultaneous laying and bonding of the sealing rings on both sides of the bipolar plate 200.

[0051] Specifically, please refer to Figure 3 and Figure 4 , Figure 3 This is a schematic diagram of the structure of the lower paving module 20 provided in this embodiment. Figure 4 The schematic diagram of the structure of the upper paving module 40 provided in this embodiment, combined with Figure 1-Figure 4The lower paving module 20 includes a first ejection structure 21 and a first placement plate 22, the first ejection structure 21 is arranged on the paving platform 10, the first placement plate 22 is arranged on the first ejection structure 21, and a first installation groove 221 for installing the first sealing ring 300 is opened; the first driving device 30 is arranged on the paving platform 10, and the upper paving module 40 includes a second ejection structure 41 and a second placement plate 42, the second ejection structure 41 is arranged on the first driving device 30, the second placement plate 42 is arranged on the second ejection structure 41, and a first installation groove 221 for installing the first sealing ring 300 is opened; the first driving device 30 is arranged on the paving platform 10, and the upper paving module 40 includes a second ejection structure 41 and a second placement plate 42, the second ejection structure 41 is arranged on the first driving device 30, and the second placement plate 42 is arranged on the second ejection structure 41, and a first installation groove 221 for installing the first sealing ring 300 is opened A second mounting groove 421 for installing the second sealing ring 400; wherein the first driving device 30 is used to drive the upper paving module 40 to move toward the lower paving module 20; when the second placement plate 42 and the first placement plate 22 press the bipolar plate 200 at the same time, the first ejection structure 21 is used to eject the first sealing ring 300 from the first mounting groove 221 and bond it to one side of the bipolar plate 200, and the second ejection structure 41 is used to eject the second sealing ring 400 from the second mounting groove 421 and bond it to the other side opposite to the bipolar plate 200.

[0052] That is to say, during paving, the first sealing ring 300 is installed in the first installation groove 221, the second sealing ring 400 is installed in the second installation groove 421, the bipolar plate 200 is installed on the first placement plate 22 after being coated with glue, and the upper paving module 40 is driven by the first driving device 30 to move toward the lower paving module 20; when the second placement plate 42 contacts the bipolar plate 200, the second placement plate 42 and the first placement plate 22 will simultaneously press the bipolar plate 200, at this time, the first ejection structure 21 can push the first sealing ring 300 is ejected from the first mounting groove 221 and bonded to one side of the bipolar plate 200. Similarly, the second ejection structure 41 can eject the second sealing ring 400 from the second mounting groove 421 and bond it to the other side opposite to the bipolar plate 200, thereby simultaneously bonding both sides of the bipolar plate 200, thereby improving the efficiency and accuracy of paving; and, through the lifting and supporting of the sealing ring by the first ejection structure 21 and the second ejection structure 41, the bonding strength between the sealing ring and the bipolar plate 200 can also be improved.

[0053] Please combine Figure 2 and Figure 4, the first driving device 30 includes a lifting mechanism 31, a rotating mechanism 32 and a rotating seat 33. The lifting mechanism 31 is arranged on the paving platform 10, the rotating mechanism 32 is connected to the lifting mechanism 31, the rotating seat 33 is connected to the rotating mechanism 32, and the second ejection structure 41 is arranged on the rotating seat 33. It is easy to understand that the rotating mechanism 32 drives the rotating seat 33 to rotate to drive the upper paving module 40 to rotate as a whole. When installing the sealing ring, the first placement plate 22 and the second placement plate 42 are both arranged upward, which can facilitate the first sealing ring 300 and the second sealing ring 400 to be installed in the first installation groove 221 and the second installation groove 421 respectively; then, the upper paving module 40 is rotated by the rotating mechanism 32, so that the first placement plate 22 and the second placement plate 42 are arranged oppositely, and then the upper paving module 40 is driven by the lifting mechanism 31 to move toward the lower paving module 20, so that the second placement plate 42 abuts against the bipolar plate 200 and squeezes the bipolar plate 200 together with the first placement plate 22.

[0054] It should be noted that, in the present embodiment, there are two rotating mechanisms 32 and two lifting mechanisms 31 , which are arranged at intervals, and both ends of the rotating seat 33 are respectively connected to the two rotating mechanisms 32 , thereby improving the stability of the upper laying module 40 during movement.

[0055] Please continue to combine Figure 2 In order to further improve the laying efficiency and accuracy, the first ejection structure 21 is slidably connected to the laying platform 10, and the bipolar plate sealing ring laying device 100 further includes a second driving device 50, which is disposed on the laying platform 10 and connected to the first ejection structure 21. In other words, the lower laying module 20 can be driven by the second driving device 50 to move relative to the laying platform 10 as a whole, thereby making it more convenient to install the sealing ring and enabling the first placement plate 22 to be accurately aligned with the second placement plate 42.

[0056] Please refer to Figure 5 and Figure 6 , Figure 5 The exploded view of the lower paving module 20 provided in this embodiment is as follows: Figure 6 The schematic diagram of the structure of the first placement plate 22 provided in this embodiment, combined with Figure 5 and Figure 6The first ejection structure 21 includes a first support plate 211, a plurality of first springs 212 and a plurality of first ejection blocks 213. The first support plate 211 is arranged on the paving platform 10, and the plurality of first springs 212 are arranged at intervals on the first support plate 211. The first placement plate 22 is arranged on a side of the plurality of first springs 212 away from the first support plate 211, and is connected to the plurality of first springs 212 at the same time; a plurality of first ejection holes 222 are opened on the bottom wall of the first mounting groove 221, and the plurality of first ejection holes 222 are arranged at intervals. The plurality of first ejection blocks 213 are arranged at intervals on the first support plate 211, and correspond to the plurality of first ejection holes 222 one by one. The first ejection blocks 213 are used to extend from the first ejection holes 222 to eject the first sealing ring 300 from the first mounting groove 221 and bond to one side of the bipolar plate 200.

[0057] That is to say, when the first placement plate 22 and the second placement plate 42 press the bipolar plate 200, the first placement plate 22 will be subjected to a reaction force, and thus move toward the first support plate 211 under the action of the first spring 212, so that the first ejection block 213 extends from the first ejection hole 222 and applies a thrust to the first sealing ring 300, thereby ejecting the first sealing ring 300 out of the first mounting groove 221 and better bonding it to the bipolar plate 200.

[0058] In order to guide and limit the movement of the first placement plate 22, in this embodiment, the first ejection structure 21 further includes a plurality of first guide posts 214, which are simultaneously provided on the first support plate 211 and the first placement plate 22 and correspond one to one with the plurality of first springs 212, which are respectively sleeved on the plurality of first guide posts 214. The provision of the first guide posts 214 can also provide a guide limit for the spring, thereby improving the movement stability of the first placement plate 22.

It is easy to understand that the structure of the first sealing ring ejection plate 23 is substantially the same as the overall structure of the first sealing ring 300, so that the plurality of first ejection blocks 213 can act on the first sealing ring ejection plate 23 at the same time, thereby ejecting the first sealing ring 300 as a whole, thereby further improving the bonding strength with the bipolar plate 200 and the paving efficiency.

[0060] Please continue to combine Figure 5 and Figure 6It should be noted that, in this embodiment, the number of the first guide column 214, the first spring 212, the first ejection block 213 and the first ejection hole 222 are all four, and the four first guide columns 214 and the four first springs 212 are respectively arranged at the four corners of the first support plate 211, and the four first ejection blocks 213 and the four first ejection holes 222 are also respectively arranged around the first support plate 211 and around the first installation groove 221 of the first placement plate 22, so as to further improve the overall paving effect of the upper paving module 40 on the first sealing ring 300. Of course, in other embodiments, the number of the first guide column 214, the first spring 212, the first ejection block 213 and the first ejection hole 222 can also be two, three or five, etc.

[0061] Similarly, please refer to Figure 7 and Figure 8 , Figure 7 The exploded view of the upper paving module 40 provided in this embodiment is as follows: Figure 8 The schematic diagram of the structure of the second placement plate 42 provided in this embodiment, combined with Figure 7 and Figure 8 The second ejection structure 41 includes a second support plate 411, a plurality of second springs 412 and a plurality of second ejection blocks 413. The second support plate 411 is arranged on the first driving device 30. The plurality of second springs 412 are arranged at intervals on the second support plate 411. The second placement plate 42 is arranged on a side of the plurality of second springs 412 away from the second support plate 411 and is connected to the plurality of second springs 412 at the same time. The bottom wall of the second mounting groove 421 is provided with a plurality of second ejection holes 422, the plurality of second ejection holes 422 are arranged at intervals, the plurality of second ejection blocks 413 are arranged at intervals on the second support plate 411 and correspond to the plurality of second ejection holes 422 one by one. The second ejection blocks 413 are used to extend from the second ejection holes 422 to eject the second sealing ring 400 from the second mounting groove 421 and bond it to the other side opposite to the bipolar plate 200.

[0062] That is, when the first placement plate 22 and the second placement plate 42 press the bipolar plate 200, the second placement plate 42 will be subjected to a reaction force, and thus move toward the second support plate 411 under the action of the second spring 412, so that the second ejection block 413 extends from the second ejection hole 422 and applies a thrust to the second sealing ring 400, thereby ejecting the second sealing ring 400 out of the second mounting groove 421 and better bonding it to the bipolar plate 200.

[0063] Similarly, in order to guide and limit the second placement plate 42 and the second spring 412 to improve the stability of the second placement plate 42, in this embodiment, the second ejection structure 41 also includes a plurality of second guide columns 414, and the plurality of second guide columns 414 are simultaneously penetrated through the second support plate 411 and the second placement plate 42, and correspond one-to-one to the plurality of second springs 412, and the plurality of second springs 412 are respectively sleeved on the plurality of second guide columns 414.

[0064] Similarly, in order to better push the second sealing ring 400 out of the second mounting groove 421, the lower paving module 20 also includes a second sealing ring ejection plate 43, which is arranged in the second mounting groove 421 and covers the plurality of second ejection holes 422 at the same time. It is easy to understand that the structure of the second sealing ring ejection plate 43 is substantially the same as the overall structure of the second sealing ring 400, so that the plurality of second ejection blocks 413 can act on the second sealing ring ejection plate 43 at the same time, thereby ejecting the second sealing ring 400 as a whole, thereby further improving the bonding strength with the bipolar plate 200 and the paving efficiency.

[0065] It should also be noted that, in the present embodiment, the number of the second guide column 414, the second spring 412, the second ejection block 413 and the second ejection hole 422 are all four; of course, in other embodiments, the above number can also be two, three or five, etc.

[0066] Since the second sealing ring 400 is arranged on the upper paving module 40, it will rotate under the action of the rotating mechanism 32 and will also rise or fall under the action of the lifting mechanism 31. Therefore, in order to improve the installation stability of the second sealing ring 400 in the second installation groove 421 and prevent it from falling during the process of moving up and down or turning over, please refer to Fig. 9 , Fig. 9 The schematic diagram of the structure of the second sealing ring ejector plate 43 provided in this embodiment, combined with Fig. 9 The second sealing ring ejection plate 43 is provided with a plurality of negative pressure adsorption holes 431 . It is easy to understand that the second sealing ring 400 is subjected to negative pressure adsorption through the plurality of negative pressure adsorption holes 431 , thereby improving the installation stability of the second sealing ring 400 .
