As shown in fig. 1, the first winding member 22 includes a first winding roller 221 and a plurality of first conveying rollers 222, where the first winding roller 221 is located at the downstream of the separating roller 21, and the plurality of first conveying rollers 222 are spaced between the separating roller 21 and the first winding roller 221, and by setting the plurality of first conveying rollers 222 to support the substrate 100, the substrate 100 can be conveyed for a long distance, and the winding effect of the substrate 100 is better.
The surface of the proton exchange membrane 200 facing the substrate 100 is a first surface, and the surface of the proton exchange membrane 200 facing away from the substrate 100 is a second surface. The proton exchange membrane processing device in this embodiment further includes a membrane covering assembly 4, where the membrane covering assembly 4 is located at one side of the stripping assembly 2, and the membrane covering assembly 4 is used to attach the protective film 300 to the second surface.

As shown in fig. 1 and 2, the film-coating assembly 4 includes a second unreeling roller 41 and a pressing roller 42, a first unreeling roller 121 being located upstream of the separating roller 21, the first unreeling roller 121 being for unreeling the protective film 300; the pressing roller 42 is disposed opposite to the separation roller 21, and the pressing roller 42 is located below the separation roller 21, with the proton exchange membrane 200 and the protective film 300 passing between the separation roller 21 and the pressing roller 42.
It will be appreciated that the second unwind roller 41 may unwind the protective film 300, pull the protective film 300 between the pressure roller 42 and the separator roller 21, and attach the protective film 300 to the second surface of the proton exchange membrane 200 under the downstream transport action of the proton exchange membrane 200.
For example, the pressing roller 42 is a rubber covered roller, and the rubber covered roller has a certain elasticity, and can apply a certain pressure to the protective film 300, so that the protective film 300 can be attached to the proton exchange membrane 200.
In the present embodiment, the separation roller 21 is an electromagnetic roller, and heating is performed by the electromagnetic roller, so that the protective film 300 and the proton exchange membrane 200 can be bonded together by hot pressing.
The heating temperature T of the electromagnetic roller is 120-150 ℃, for example, T may be 120 ℃, 122 ℃, 125 ℃, 128 ℃, 130 ℃, 132 ℃, 135 ℃, 137 ℃, 140 ℃, 143 ℃, 145 ℃, 148 ℃ or 150 ℃. In the above temperature range, the bonding effect between the protective film 300 and the proton exchange membrane 200 can be improved. However, if the heating temperature of the electromagnetic roller is too low, the bonding effect of the protective film 300 and the proton exchange membrane 200 is poor, and if the heating temperature of the electromagnetic roller is too high, the protective film 300 and the proton exchange membrane 200 are damaged.
As shown in fig. 1 and 3, the drying assembly 3 includes a cabinet 31, a support member 32, and a drying member 33. The proton exchange membrane 200 passes through the tank 31; the support component 32 is arranged in the drying box 14, and the proton exchange membrane 200 bypasses the support component 32; the drying part 33 is disposed in the drying box 14, and the drying part 33 is used for drying the proton exchange membrane 200 passing through the box 31.
It can be understood that when the proton exchange membrane 200 passes through the case 31, the proton exchange membrane 200 is supported by the supporting member 32, and the drying member 33 dries the proton exchange membrane 200, so that the drying effect of the drying member 33 on the proton exchange membrane 200 is better because the proton exchange membrane 200 is separated from the substrate 100.
As shown in fig. 1 and 3, the support member 32 includes a plurality of first support rollers, and the proton exchange membrane 200 is sequentially wound on the plurality of first support rollers, and the plurality of first support rollers are staggered so that a conveying path of the proton exchange membrane 200 in the case 31 is S-shaped.
The conveying path of the proton exchange membrane 200 in the box 31 is in an S shape, so that the feeding length of the proton exchange membrane 200 is increased, the drying time of the proton exchange membrane 200 is increased, the drying effect is better, the residual rate of the solvent is reduced, and the space occupied by the box 31 can be saved.
For example, each two first support rollers are arranged in a group, and in the length direction of the box 31, a plurality of groups of first support rollers are arranged in an up-down, … … manner, each group of first support rollers located above is located at the same height, and each group of first support rollers located below is located at the same height. Of course, those skilled in the art may arrange the first support roller in other arrangements, and are not limited herein.
In this embodiment, the proton exchange membrane 200 has a running length of 8m to 10m in the case 31. Within this range, the proton exchange membrane 200 is made to have a good drying effect while ensuring the production efficiency of the proton exchange membrane 200.
For example, the running length of the proton exchange membrane 200 in the box 31 may be 8.0m, 8.2m, 8.5m, 8.7m, 9.0m, 9.2m, 9.5m, 9.8m or 10m, etc., if the running length of the proton exchange membrane 200 in the box 31 is too long, the production efficiency of the proton exchange membrane 200 may be reduced, and if the running length is too short, the drying effect of the proton exchange membrane 200 may not be ensured, which is unfavorable for reducing the solvent residual rate in the proton exchange membrane 200.
In this embodiment, the surface of the proton exchange membrane 200 facing the substrate 100 is a first surface, and the surface of the proton exchange membrane 200 facing away from the substrate 100 is a second surface. The drying part 33 comprises a first air nozzle 331 and a second air nozzle 332, the first air nozzle 331 is connected with the box 31, and an air outlet of the first air nozzle 331 faces the first surface; the second tuyere 332 is connected with the box 31, and an air outlet of the second tuyere 332 faces the second surface.
Drying the proton exchange membrane 200 by blowing air from the upper and lower directions using the first and second air nozzles 331 and 332 can more uniformly dry the proton exchange membrane 200.
For example, a plurality of first air nozzles 331 are arranged at the top of the case 31 along the length direction of the case 31, and the plurality of first air nozzles 331 are uniformly spaced apart. The bottom of the case 31 is provided with a plurality of second tuyeres 332 arranged along the length direction of the case 31, and the plurality of second tuyeres 332 are uniformly spaced apart, so that the drying of the proton exchange membrane 200 can be more uniform.
In this embodiment, the first air nozzle 331 is an air knife type air nozzle.
It will be appreciated that the first air nozzle 331 may be capable of directing a large amount of air in a short period of time, and concentrating the air, so that the first surface of the proton exchange membrane 200 may be rapidly dried. The specific construction of the air knife tuyere is conventional prior art and will not be described in detail here.
In the present embodiment, the second tuyere 332 is an orifice plate tuyere.
It should be noted that, since the protective film 300 is attached to the second surface of the proton exchange membrane 200, and the air outlet area of the second air nozzle 332 is large, the protective film 300 can be better protected while the second surface of the proton exchange membrane 200 is dried, so as to prevent the protective film 300 from being damaged by concentrated air outlet. The specific construction of the orifice plate tuyere is conventional prior art and will not be described in detail here.
As shown in fig. 1, the exchange membrane processing device in this embodiment further includes a second winding component 5, where the second winding component 5 is disposed at an output end of the drying assembly 3, and the second winding component 5 is used to wind the proton exchange membrane 200 dried by the drying assembly 3.
It can be appreciated that the dried proton exchange membrane 200 can be wound by the second winding member 5, so as to facilitate subsequent use.
For example, the second winding member 5 includes a second winding roller 51 and a plurality of second conveying rollers 52, the second winding roller 51 is located downstream of the drying assembly 3, and the plurality of second conveying rollers 52 are spaced between the second winding roller 51 and the drying assembly 3. The specific structures of the second wind-up roller 51 and the second conveying roller 52 are conventional prior art, and are not limited herein.
The processing method of the proton exchange membrane in the embodiment utilizes the proton exchange membrane processing device, and the processing method of the proton exchange membrane comprises the following steps:
s10, forming a proton exchange membrane 200 on a substrate 100;
s20, separating the substrate 100 and the proton exchange membrane 200;
and S30, drying the proton exchange membrane 200 separated from the substrate 100.
In this embodiment, after the proton exchange membrane 200 is formed on the substrate 100, the substrate 100 and the proton exchange membrane 200 are separated, so that the substrate 100 can be recovered and reused, resources can be saved, and production cost is reduced.
In this example, the speed of the substrate 100 was 3m/min to 5 m/min. By controlling the speed of the substrate 100, the production efficiency can be improved while the drying speed of the proton exchange membrane 200 is ensured.
For example, the feed speed of the substrate 100 may be 3m/min, 3.2m/min, 3.5m/min, 3.7m/min, 3.9m/min, 4.0m/min, 4.3m/min, 4.5m/min, 4.7m/min, 5.0m/min, or the like. If the running speed of the substrate 100 is too high, the drying effect of the proton exchange membrane 200 is affected, and if the running speed of the substrate 100 is too low, the production efficiency is lowered.
