An elastic stabilization device 100 for a membrane electrode assembly 200 according to an embodiment of the first aspect of the present invention is described below with reference to fig. 1 to 3.
As shown in fig. 1 and 2, an elastic stabilization device 100 for a membrane electrode assembly 200 according to an embodiment of the present invention includes: an upper platen 10, a lower platen 20, and a plurality of roller assemblies.
Specifically, the upper platen 10 and the lower platen 20 are arranged in parallel and spaced apart in the up-down direction (as shown in fig. 1, the upper platen 10 and the lower platen 20 are arranged in opposition to each other up and down), and the upper platen 10 is located directly above the lower platen 20.
The plurality of roller assemblies include two sets of first and second roller assemblies 30 and 40, respectively, the first roller assembly 30 is disposed on the upper platen 10, the second roller assembly 40 is supported on the lower platen 20, and the first and second roller assemblies 30 and 40 are spaced apart in the up-down direction.
Further, the first roller assemblies 30 include a plurality of rollers spaced apart on the upper platen 10 in the left-right direction (as shown in fig. 1, a plurality of first roller assemblies 30 spaced apart on the upper platen 10), and the second roller assemblies 40 include a plurality of rollers spaced apart on the lower platen 20 in the left-right direction (as shown in fig. 1, a plurality of second roller assemblies 40 spaced apart on the lower platen 20).
The first roller assemblies 30 and the second roller assemblies 40 are arranged in a one-to-one correspondence manner, and the first roller assemblies 30 and the second roller assemblies 40 are mutually matched to perform pressure maintaining treatment on at least one membrane electrode assembly 200, as shown in fig. 1, the first roller assemblies 30 and the second roller assemblies 40 are arranged in a one-to-one correspondence manner in the up-down direction, so as to ensure the pressure required for the elastic stabilization of the membrane electrode assembly 200.
It can be understood that the membrane electrode assembly 200 can be put on the second roller assembly 40 from one side (the right side shown in fig. 1 and fig. 2) of the elastic stabilization device 100, and the membrane electrode assembly 200 is rolled and compressed by the corresponding cooperation of the first roller assembly 30 and the second roller assembly 40, so as to meet the elastic stabilization process of the membrane electrode assembly 200 and eliminate the air leakage condition of the membrane electrode assembly 200.
According to the elastic stabilization device 100 for the membrane electrode assembly 200 of the embodiment of the invention, the membrane electrode assembly 200 is rolled and compressed by the upper and lower rows of roller assemblies, so that the pressure maintaining effect on the membrane electrode assembly 200 is good, and the gas leakage phenomenon of the membrane electrode assembly 200 is effectively avoided.
According to an embodiment of the present invention, each of the first and second roller assemblies 30 and 40 includes a support rod 41 and a roller 42, that is, each of the first roller assemblies 30 includes a support rod 41 and a roller 42, each of the second roller assemblies 40 includes a support rod 41 and a roller 42, the first and second roller assemblies 30 and 40 have the same structural composition, the support rod 41 of the first roller assembly 30 is connected between the upper platen 10 and the roller 42, and the support rod 41 of the second roller assembly 40 is connected between the lower platen 20 and the roller 42. The roller 42 of the first roller assembly 30 and the roller 42 of the second roller assembly 40 are disposed opposite to each other in the up-down direction.
Therefore, the membrane electrode assembly 200 is rolled and compressed through the upper row of rollers 42 and the lower row of rollers 42, pressure maintaining treatment is further carried out on the membrane electrode assembly 200, the elastic stabilization process is optimized, and compared with a mode of carrying out pressure maintaining treatment on the membrane electrode assembly 200 by simply adopting a servo press in the related art, the air leakage phenomenon can be effectively avoided.
As shown in fig. 1, according to an alternative example of the present invention, the supporting rod 41 of the first roller assembly 30 is vertically fixed on the upper plate 10, the pressure of the upper plate 10 can be more transmitted to the roller 42 of the first roller assembly 30, and the supporting rod 41 of the second roller assembly 40 is vertically fixed on the lower plate 20, so that the first roller assembly 30 and the second roller assembly 40 cooperate to better roll and press the membrane electrode assembly 200.
According to another alternative example of the present invention, the specific one of the plurality of first roller assemblies 30 is defined in the middle of the specific one of the plurality of first roller assemblies 30 in the left-right direction, the support rods 41 of the plurality of first roller assemblies 30 positioned at the left side of the specific one of the plurality of first roller assemblies 31 are all the same in length, and the support rods 41 of the plurality of first roller assemblies 30 positioned at the right side of the specific one of the plurality of first roller assemblies 31 are gradually reduced in length from left to right. According to still another alternative example of the present invention, the support bars 41 of the plurality of second roller assemblies 40 are all the same length.
It should be noted that the reserved length of the first transmission belt 43 on the left side of the specific roller assembly 31 is greater than the longest side length of the membrane electrode assembly 200, so that when the membrane electrode assembly 200 moves to the left side of the specific roller assembly 31, the first roller assembly 30 and the second roller assembly 40 cooperate with each other up and down to perform pressure maintaining treatment on the membrane electrode assembly 200, and the pressure maintaining effect on the membrane electrode assembly 200 is ensured to be more uniform.
As shown in fig. 1 and fig. 2, counting from left to right, with the 6 th roller assembly of the first roller assemblies 30 as a boundary, the first roller assemblies 30 on the right side of the 6 th roller assembly gradually extend obliquely upward, that is, the length of the support rod 41 of the first roller assemblies 30 on the right side of the 6 th roller assembly gradually decreases to make room for the material feeding of the membrane electrode assembly 200; the support rods 41 of the plurality of first roller assemblies 30 on the left side of the 6 th roller assembly have the same length, and are used for performing pressure maintaining treatment on the conveyed membrane electrode assembly 200 to ensure the elastic stabilization process of the membrane electrode assembly 200.
It can be understood that a plurality of support rods 41 are vertically fixed on the upper press plate 10, the length of the plurality of support rods 41 in the left-to-right direction is constant for a certain number of pieces, and the length of the support rods 41 is decreased from a specific one of the support rods 41, so that the rollers 42 on the decreased portion of the support rods 41 exhibit a certain inclination.
According to another embodiment of the present invention, the elastic stabilization device 100 for the membrane electrode assembly 200 further includes: the first conveyor belt 43 is wrapped on the rollers 42 of the first roller assemblies 30, and the second conveyor belt 44 is wrapped on the rollers 42 of the second roller assemblies 40, so as to support the membrane electrode assembly 200 and convey the membrane electrode assembly 200.
Further, the right distance between the first conveyor belt 43 and the second conveyor belt 44 in the up-down direction is determined by the product of the number of the membrane electrode assemblies 200 on the second conveyor belt 44 and the total thickness of the membrane electrode assemblies 200 on the second conveyor belt 44, so as to reasonably determine the right distance between the first conveyor belt 43 and the second conveyor belt 44. The left distance between the first conveyor belt 43 and the second conveyor belt 44 in the up-down direction is the product of the number of the membrane electrode assemblies 200 and the theoretical compression thickness of the membrane electrode assemblies 200 on the second conveyor belt 44, so as to reasonably determine the left distance between the first conveyor belt 43 and the second conveyor belt 44.
Alternatively, the left distance between the first conveyor belt 43 and the second conveyor belt 44 may be directly determined, that is, the left distance between the first conveyor belt 43 and the second conveyor belt 44 in the up-down direction is the product of the number of the membrane electrode assemblies 200 and the theoretical compression thickness of the membrane electrode assemblies 200 on the second conveyor belt 44.
According to another alternative example of the present invention, the leftmost roller 42 and the rightmost roller 42 of the plurality of second roller assemblies 40 are respectively connected to a first motor (not shown) for respectively driving the leftmost roller 42 and the rightmost roller 42 to rotate, so as to drive the second conveyor belt 44 to operate, thereby achieving the requirement of conveying the film electrode assembly 200.
According to yet another embodiment of the present invention, the elastic stabilization device 100 for the membrane electrode assembly 200 further comprises a servo press 50. The servo press 50 and the upper press plate 10 are connected through a press rod 60 to drive the upper press plate 10 to press down, so as to provide downward pressure for the membrane electrode assembly 200, and meanwhile, the upper row of rollers 42 and the lower row of rollers 42 are arranged in a one-to-one correspondence manner, so that the pressure required by elastic stabilization can be ensured.
As shown in fig. 3, according to the elastic stabilization method of the membrane electrode assembly 200 according to the second aspect of the embodiment of the present invention, the elastic stabilization device 100 for the membrane electrode assembly 200 according to the above embodiment performs the pressure holding process on the membrane electrode assembly 200, and the method includes the specific steps of:
s1, transporting one or more membrane electrode assemblies 200 from the right side of the elastic stabilization device 100 onto the second conveyor belt 44;
s2, the second conveyor belt 44 conveys the membrane electrode assembly 200 from right to left at a certain speed, in the moving process of the membrane electrode assembly 200, the position sensor taking the first conveyor belt 43 as the reference monitors the vertical distance from the uppermost membrane electrode assembly 200 to the first conveyor belt 43, and when the vertical distance is too large, the servo press 50 moves downwards;
s3, when the uppermost membrane electrode assembly 200 contacts the second conveyor belt 44, the servo press 50 increases the pressure slowly, and after the whole membrane electrode assembly 200 enters the left side of the specific first roller assembly 30, the upper press plate 10 and the lower press plate 20 cooperate to perform pressure maintaining treatment on the membrane electrode assembly 200;
s4, simultaneously vibrating the roller 42 of the first roller assembly 30 and the roller 42 of the second roller assembly 40 at a certain frequency, and heating the roller 42 of the first roller assembly 30 and the roller 42 of the second roller assembly 40;
s5, putting the membrane electrode assemblies 200 of the next batch onto the second conveyor belt 44 from the right side of the elastic stabilizing device 100;
and S6, continuing to start a new elastic stabilization process, and circularly performing the steps.
According to the elastic stabilization method of the membrane electrode assembly 200 of the embodiment of the invention, the membrane electrode assembly 200 is rolled and compressed by the upper and lower rows of roller assemblies, so that the pressure maintaining effect on the membrane electrode assembly 200 is good, and the gas leakage phenomenon of the membrane electrode assembly 200 is effectively avoided.
It will be appreciated that when the membrane electrode assembly 200 is in motion, the position sensor with reference to the first conveyor belt 43 monitors the vertical spacing between the uppermost membrane electrode assembly 200 and the first conveyor belt 43, and when the vertical spacing is too large, the upper servo press 50 will move downward.
When the uppermost membrane electrode assembly 200 contacts the first conveyor belt 43, the pressure is slowly increased, after the whole membrane electrode assembly 200 enters the horizontal area of the first conveyor belt, the pressure maintaining process is started, and simultaneously, the next batch (piece) of membrane electrode assemblies 200 are placed on the second conveyor belt 44 on the right, and a new elastic stabilization process is continuously started.
In addition, vibration and heating also accelerate the elastic stabilization process, and after the pressing is stabilized, the roller 42 can be given vibration with a certain frequency, and the elastic stabilization process can be optimized by heating the roller 42.
In the related art, before stacking the membrane electrode assemblies, a servo press can be used for carrying out pressure maintaining treatment on the membrane electrode assemblies for a period of time to eliminate the elastic deformation of the membrane electrode assemblies, but due to the fact that the roughness and the parallelism of upper and lower pressure heads of the servo press are different, and meanwhile, the pressure maintaining time is too long, the air leakage of the membrane electrode assemblies can occur; in order to improve the speed of material preparation in actual production, a plurality of (more than two) membrane electrode assemblies can be processed in one elastic stabilization process, and a servo press is used for elastic stabilization in the process of elastic stabilization.
In the application, on one hand, the membrane electrode assembly 200 is rolled and compressed by the upper and lower rows of roller assemblies, and the elastic stabilization process is performed by the relative rolling and compression of the upper and lower rows of rollers 42, so that the pressure maintaining effect on the membrane electrode assembly 200 is good, and the gas leakage phenomenon of the membrane electrode assembly 200 is effectively avoided; on the other hand, in the process of performing the elastic stabilization process on the membrane electrode assembly 200, the feeding and discharging processes of the membrane electrode assembly 200 on the elastic stabilization device 100 are continuously and uninterruptedly performed, which conforms to the high-efficiency production of the assembly line, and greatly improves the production efficiency. Compared with the mode of increasing the production efficiency of the servo press in the related art, the method has the advantages that the cost is lower and the continuity of the process is more facilitated by increasing the number of the rollers 42 and the length of the conveyor belt. Furthermore, the elastic stabilization process is further optimized by adding modes such as variable frequency vibration, heating and the like on the basis of the roller 42.
