DETAILED DESCRIPTION

[0023] In order to make the purpose, technical solution and advantages of the embodiments of the present application clearer, the technical solution in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are part of the embodiments of the present application, rather than all the embodiments. The components of the embodiments of the present application described and shown in the drawings here can be arranged and designed in various different configurations.

[0024] Therefore, the following detailed description of the embodiments of the present application provided in the accompanying drawings is not intended to limit the scope of the present application for which protection is sought, but merely represents selected embodiments of the present application. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in the field without creative work are within the scope of protection of the present application.

[0025] like Figure 1 , Figure 2 and Figure 3 As shown, the fuel cell double-layer frame preparation device 100 of some embodiments of the present application includes a first frame unwinding mechanism 111, a first frame rolling cutting mechanism 112, a second frame unwinding mechanism 121, a second frame rolling cutting mechanism 122 and a pressing mechanism 130. The first frame unwinding mechanism 111 is used to unwind the first frame material strip 210. The first frame rolling cutting mechanism 112 is used to cut out the first active area opening 211 on the first frame material strip 210; the second frame unwinding mechanism 121 is used to unwind the second frame material strip 220; the pressing mechanism 130 is used to press the first frame material strip 210 and the second frame material strip 220 with the first active area opening 211 which are stacked; the second frame rolling cutting mechanism 122 is arranged downstream of the pressing mechanism 130, and is used to cut out the second active area opening 221 on the second frame material strip 220.

[0026] The opening areas of the first active area opening 211 and the second active area opening 221 are different. For example, the projection of the opening area of ​​the second active area opening 221 falls within the opening area of ​​the first active area opening 211. The fuel cell double-layer frame preparation equipment 100 can be used to prepare an upper frame material strip, and can also be used to prepare a lower frame material strip, which is used as the raw material for preparing a membrane electrode in the next process. The first active area opening 211 and the second active area opening 221 correspond to the catalyst coating area of ​​the membrane electrode CCM sheet.

[0027] The fuel cell double-layer frame preparation device 100 of the embodiment of the present application comprises a first frame rolling cutting mechanism 112, a second frame rolling cutting mechanism 122 and a pressing mechanism 130. The first frame rolling cutting mechanism 112 rolls the first frame material strip 210 to form a first active area opening 211. After pressing the first frame material strip 210 with the first active area opening 211 and the second frame material strip 220, the second frame rolling cutting mechanism 122 rolls the second frame material strip 220 to form a second active area opening 221, thereby forming a double-layer frame material strip. Since the first frame material strip 210 and the second frame material strip 220 are both rolled, compared with the flat pressing die cutting process, it has the advantage of reducing the tension fluctuation of the material strip, thereby reducing the quality fluctuation of the double-layer frame finished material strip and improving the production quality of the double-layer frame finished material strip.

[0028] In some embodiments of the present application, the fuel cell double-layer frame preparation equipment 100 also includes a base film mask providing mechanism 140, which is arranged upstream of the first frame rolling cutting mechanism 112, including a base film mask unwinding mechanism 141, a mask rolling cutting mechanism 142 and a mask winding mechanism 143. The base film mask unwinding mechanism 141 is used to unwind a base film mask tape 230. The base film mask tape 230 includes a stacked base film tape 231 and a mask tape 232. The mask rolling cutting mechanism 142 is used to cut the mask tape 232 to form a mask sheet 233 covering the first active area opening 211. The mask winding mechanism 143 is used to wind up the waste mask tape.

[0029] The mask sheet 233 covers the first active area opening 211, exposing the frame structure of the edge of the first active area opening 211; the waste mask tape is the tape after the mask sheet 233 is cut and removed; the mask roller cutting mechanism 142 is arranged upstream of the first frame roller cutting mechanism 112, and the base film mask tape 230 is formed into a stacked base film tape 231 and a mask sheet 233 after being roller cut by the mask roller cutting mechanism 142, and enters the first frame roller cutting mechanism 112 together with the first frame tape 210, and the mask sheet 233 covers the first active area opening 211; the mask winding mechanism 143 is arranged downstream of the mask roller cutting mechanism 142, and the waste mask tape is torn off from the surface of the base film tape 231 before the base film tape 231 enters the first frame roller cutting mechanism 112, and is wound up by the mask winding mechanism 143.

[0030] With this arrangement, the roll-cutting process of the first frame material strip 210 can be completed by using the base film strip 231 as a supporting film, and a mask sheet 233 covering the first active area opening 211 is sandwiched between the base film strip 231 and the first frame material strip 210 .

[0031] In some embodiments of the present application, the fuel cell double-layer frame preparation equipment 100 also includes a first protective film winding mechanism 113, which is arranged downstream of the first frame roller cutting mechanism 112 and is used to roll up the first protective film strip 212 on the surface of the first frame strip 210.

[0032] The surface of the first frame material tape 210 unrolled by the first frame unrolling mechanism 111 is covered with a first protective film material tape 212. After roller cutting forms the first active area opening 211, the first protective film material tape 212 needs to be torn off the first frame material tape 210 to facilitate the pressing of the first frame material tape 210 and the second frame material tape 220.

[0033] In some embodiments of the present application, the fuel cell double-layer frame preparation equipment 100 also includes a first waste discharge mechanism 114, including a first tape unwinding mechanism 1141, a first adhesive roller 1142 and a first tape winding mechanism 1143. The first tape unwinding mechanism 1141 is used to unwind the first tape 240, the first adhesive roller 1142 is arranged downstream of the first frame roller cutting mechanism 112, and the first tape winding mechanism 1143 is used to wind up the first tape 240 with waste.

[0034] Based on the implementation method of "the surface of the first border material tape 210 is covered with the first protective film material tape 212", the waste generated at the first border roller cutting mechanism 112 refers to the double-layer film waste of the first border material tape 210 and the first protective film material tape 212 corresponding to the shape of the first active area opening 211, and the first protective film winding mechanism 113 is arranged downstream of the first adhesive roller 1142, that is, the waste is discharged first and then the first protective film material tape 212 is torn off.

[0035] This arrangement can remove waste materials generated during the frame roller cutting process, making it easier to press the first frame material strip 210 and the second frame material strip 220 together in the next process.

[0036] The second frame unwinding mechanism 121 and the first roller cutting mechanism 112 are both arranged upstream of the laminating mechanism 130. The second frame material strip 220 unrolled by the second frame unwinding mechanism 121 enters the laminating mechanism 130 together with the stacked base film material strip 231, the mask sheet material 233 and the first frame material strip 210 with the first active area opening 211.

[0037] In some embodiments of the present application, the laminating mechanism 130 is a pair of hot pressing rollers, which use a hot pressing composite process to hot press the first frame material strip 210 and the second frame material strip 220 into one; in other embodiments, one of the rollers may be a hot roller, or both rollers may be pressing rollers, and a heating device may be provided from the outside.

[0038] In some embodiments of the present application, two first border roller cutting mechanisms 112 are provided.

[0039] The first specification roller cutting mechanism 1121 and the second specification roller cutting mechanism 1122 are arranged side by side, and the corresponding roller cutting mechanism is turned on according to the specific frame size specification produced, and the other roller cutting mechanism is stopped. For example, one of the first specification roller cutting mechanism 1121 and the second specification roller cutting mechanism 1122 corresponds to the upper frame material strip, and the other roller cutting mechanism corresponds to the lower frame material strip.

[0040] In some other embodiments of the present application, two second frame roller cutting mechanisms 122 are provided.

[0041] The third specification roller cutting mechanism and the fourth specification roller cutting mechanism (not shown in the figure) are arranged side by side. The corresponding roller cutting mechanism is turned on according to the specific frame size specification produced, and the other roller cutting mechanism is stopped. One of the third specification roller cutting mechanism and the fourth specification roller cutting mechanism corresponds to the upper frame material strip, and the other roller cutting mechanism corresponds to the lower frame material strip.

[0042] In some embodiments of the present application, the fuel cell double-layer frame preparation equipment 100 also includes a second waste discharge mechanism 123, including a second tape unwinding mechanism 1231, a second adhesive roller 1232 and a second tape winding mechanism 1233, the second tape unwinding mechanism 1231 is used to unwind the second tape 250, the second adhesive roller 1232 is arranged downstream of the second frame rolling and cutting mechanism 122, and the second tape winding mechanism 1233 is used to wind up the second tape 250 with waste.

[0043] The second waste discharge mechanism 123 removes the waste produced by the second frame roller cutting mechanism 122 by the second adhesive roller 1232 . The working principle of the second waste discharge mechanism 123 is similar to that of the first waste discharge mechanism 114 , which will not be further described here.

[0044] It can be understood that the surface of the second frame material tape 220 unrolled by the second frame unwinding mechanism 121 is covered with the second protective film material tape 222, and the waste generated at the second frame roller cutting mechanism 122 refers to the double-layer film waste of the second frame material tape 220 corresponding to the shape of the second active area opening 221 and the second protective film material tape 222.

[0045] Through this arrangement, waste materials generated during the frame roller cutting process can be removed, thereby forming a double-layer frame finished material strip 200.

[0046] The fuel cell double-layer frame manufacturing device 100 further includes a first driving roller mechanism 151 , a second driving roller mechanism 152 and a third driving roller mechanism 153 .

[0047] The first driving roller mechanism 151 is arranged between the mask rolling cutting mechanism 142 and the first frame rolling cutting mechanism 112, and is used to drive the stacked base film strip 231, the mask sheet 233, the first frame strip 210 that has not been rolled, and the first protective film strip 212 on the surface to move forward; the second driving roller mechanism 152 is arranged downstream of the first adhesive roller 1142, and is used to drive the stacked base film strip 231, the mask sheet 233, the first frame strip 210 with the first active area opening 211, and the first protective film strip 212 on the surface to move forward; the third driving roller mechanism 153 is arranged downstream of the second adhesive roller 1232, and is used to drive the double-layer frame finished product strip 200 to move forward, and the double-layer frame finished product strip 200 includes the stacked base film strip 231, the mask sheet 233, the first frame strip 210 with the first active area opening 211, the second frame strip 220 with the second active area opening 221, and the second protective film strip 222.

[0048] In some embodiments of the present application, the fuel cell double-layer frame preparation equipment 100 further includes a finished product visual inspection mechanism 160 , which is disposed downstream of the second frame roller cutting mechanism 122 .

[0049] The finished product visual inspection mechanism 160 includes a CCD camera, a backlight source, an adjustment bracket, etc., and detects the roll-cut size of the double-layer frame finished product strip 200 through high-speed flying photography.

[0050] The finished product visual inspection mechanism 160 can detect the position of the second active area opening 221 or the first active area opening 211, thereby providing reference data for the rhythm of the next process, and can also detect whether the roller cutting quality is qualified through contour comparison.

[0051] The fuel cell double-layer frame preparation equipment 100 is also provided with visual detection mechanisms on the feed side of the pressing mechanism 130 and the feed side of the second frame roller cutting mechanism 122, respectively, for providing reference data for the pressing rhythm of the pressing mechanism 130 and the rolling rhythm of the second frame roller cutting mechanism 122, so that the positions of the first active area opening 211 and the second active area opening 221 correspond.

[0052] In some embodiments of the present application, the fuel cell double-layer frame preparation device 100 further includes a labeling mechanism 170 , which is disposed downstream of the second frame rolling mechanism 122 .

[0053] By providing the labeling mechanism 170 , it is possible to mark the double-layer frame finished product strip 200 , and mark unqualified segments according to the inspection results of the finished product visual inspection mechanism 160 .

[0054] In some embodiments of the present application, the fuel cell double-layer frame preparation equipment 100 further includes a finished product winding mechanism 180 for winding up the double-layer frame finished product strip 200 .

[0055] The double-layer frame finished material strip 200 includes a stacked bottom film material strip 231 , a mask sheet material 233 covering the first active area opening 211 , a first frame material strip 210 with the first active area opening 211 , a second frame material strip 220 with the second active area opening 221 , and a second protective film material strip 222 .

[0056] The finished product winding mechanism 180 can be used to wind up the double-layer frame finished product strip 200 to provide the finished product strip for the next process.

[0057] The membrane electrode production equipment of some embodiments of the present application includes a fuel cell double-layer frame preparation equipment 100.

[0058] Due to the characteristics of the fuel cell double-layer frame preparation device 100, the production quality of the MEA finished material strip of the membrane electrode production equipment is also improved.

[0059] The working principle of the fuel cell double-layer frame preparation device 100 of the embodiment of the present application is as follows:

[0060] The base film mask unwinding mechanism 141 unwinds the base film mask material strip 230, which is rolled and cut by the mask rolling cutting mechanism 142 to form a mask sheet 233, and the waste mask material strip is rolled up by the mask rolling mechanism 143;

[0061] The first frame unwinding mechanism 111 unwinds the first frame material strip 210, and the bottom film material strip 231 carries the mask sheet 233 and is stacked with the first frame material strip 210 and enters the first frame roller cutting mechanism 112 together, and the first active area opening 211 is cut out on the first frame material strip 210, and the mask sheet 233 covers the first active area opening 211, and the first waste discharge mechanism 114 removes the double-layer film waste of the first protective film material strip 212 and the first frame material strip 210 at the first active area opening 211, and then the first protective film winding mechanism 113 winds up the first protective film material strip 212;

[0062] The second frame unwinding mechanism 121 unwinds the second frame material strip 220, and enters the pressing mechanism 130 together with the stacked bottom film material strip 231, the mask film sheet 233 and the first frame material strip 210 with the first active area opening 211. After hot pressing and laminating, the first frame material strip 210 and the second frame material strip 220 are compounded into one, and then pass through the second frame roller cutting mechanism 122 and the second waste discharge mechanism 123 in sequence, and the second active area opening 221 is cut out on the second frame material strip 220, and the double-layer film waste of the second protective film material strip 222 and the second frame material strip 220 at the second active area opening 221 is removed, so as to form a double-layer frame finished product material strip 200, and the bottom film material strip 231 and the second protective film material strip 222 respectively play a protective role from both sides of the material strip;

[0063] The double-layer frame finished material strip 200 passes through the finished product visual inspection mechanism 160 and the labeling mechanism 170 and is then rolled up by the finished product rolling mechanism 180 .

[0064] The entire machine layout of the fuel cell double-layer frame preparation equipment 100 in the embodiment of the present application is reasonable, and the space utilization rate is high. The machine does not stop during the process of cutting the active area opening of the double-layer frame, and automatic production can be achieved by replacing the roller cutting mechanism when the upper frame material strip and the lower frame material strip are switched, thereby avoiding manual replacement of the cutting die, and the material strip fluctuation range is small, with high production quality.

[0065] It should be noted that, in the absence of conflict, the features in the embodiments of this application may be combined with each other.
