[0047] 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.

[0048] 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.

[0049] like Figure 1 , Figure 2 and Fig.16As shown, the membrane electrode production equipment 100 of the embodiment of the present application includes an upper frame unwinding module 110, a CCM cutting and transferring module 120, a lower frame cutting and transferring module 130, a thermal composite module 140 and a finished product cutting and peeling module 150. The finished product cutting and peeling module 150 is located downstream of the thermal composite module 140, and includes a finished product cutting mechanism 151 and a finished product peeling mechanism 154. The upper frame unwinding module 110 is used to provide an upper frame material strip 212, the CCM cutting and transferring module 120 is used to provide a CCM sheet material 222, and the lower frame cutting and transferring module 130 is used to provide a lower frame half-cut transfer material strip 240. The lower frame half-cut transfer material strip 240 includes a stacked lower frame transfer film material strip 241 and a lower frame sheet material 242. The thermal composite module 140 is used to receive the upper frame material strip 212, the CCM sheet material 222 and the lower frame half-cut transfer material strip 240, and hot press to form a composite material strip 200. The finished product cutting mechanism 151 is used to half-cut the composite material strip 200 to form a half-cut MEA material strip 260, which includes a stacked lower frame transfer film material strip 241 and an MEA sheet 300; the finished product peeling mechanism 154 is used to peel the MEA sheet 300 off the lower frame half-cut transfer material strip 240 and output the MEA sheet 300.

[0050] It can be understood that the membrane electrode production equipment 100 of the embodiment of the present application is used to produce MEA sheets 300, that is, membrane electrodes for hydrogen fuel cells. Fig.16 As shown, the composite material strip 200 includes a stacked upper frame material strip 212, a CCM sheet 222 and a lower frame half-cut transfer material strip 240. After the composite material strip 200 passes through the finished product cutting and peeling module 150, the MEA sheet 300 is formed. The MEA sheet 300 includes the CCM sheet 222 and an upper frame sheet 213 and a lower frame sheet 242 on both sides.

[0051] The membrane electrode production equipment 100 of the embodiment of the present application is used to produce MEA sheets 300, and a half-cutting process is used to form CCM sheets 222 and lower frame sheets 242, and the sheets are bonded to the transfer film tape, and the upper frame tape 212, CCM sheets 222 and lower frame half-cut transfer tape 240 enter the thermal composite module 140 for hot pressing composite to form a composite tape 200, and then the composite tape 200 is cut and peeled to form MEA sheets 300. Since the upper frame tape 212, CCM sheets 222 and lower frame half-cut transfer tape 240 are fed separately, the conveying rhythm and quality inspection of the three can be independently controlled, so that the three raw materials entering the thermal composite module 140 are of controllable quality and high-precision bonding, which improves the qualified rate of finished products and quality control accuracy.

[0052] The structure of each module of the membrane electrode production equipment 100 of the embodiment of the present application is explained in detail below.

[0053] The upper frame unwinding module 110 is used to load the upper frame coil material tape 210 and provide the upper frame material tape 212 to the thermal composite module 140 .

[0054] like Figure 3 As shown, in some embodiments of the present application, the upper frame unwinding module 110 includes an upper frame unwinding mechanism 111 and an upper frame protective film winding mechanism 112, the upper frame unwinding mechanism 111 is used to unwind the upper frame coil material strip 210, and the upper frame coil material strip 210 includes a stacked upper frame protective film strip 211 and an upper frame strip 212 (such as Fig.16 As shown), the upper frame protective film winding mechanism 112 is used to wind up the upper frame protective film strip 211.

[0055] The upper frame unwinding module 110 further includes an upper frame deviation correction mechanism 113, an upper frame tape connection platform 114, a tension swing roller 115, and an upper frame visual positioning mechanism 116. During the unwinding process of the upper frame unwinding mechanism 111, the upper frame protective film winding mechanism 112 winds up the upper frame protective film material strip 211, and the upper frame protective film material strip 211 is automatically peeled off, and the upper frame material strip 212 passes through the upper frame deviation correction mechanism 113, the upper frame tape connection platform 114, and the tension swing roller 115 in sequence and then enters the thermal composite module 140.

[0056] Through this arrangement, the upper frame protection film tape 211 can be rolled up to unroll the upper frame tape 212 toward the thermal composite module 140 .

[0057] The upper frame visual positioning mechanism 116 is a common CCD camera, which visually positions the cutting features of the upper frame strip 212 as a reference for subsequent bonding. The upper frame visual positioning mechanism 116 is disposed downstream of the tension swing roller 115, that is, disposed near the thermal composite module 140, thereby improving the beat control accuracy of the upper frame strip 212.

[0058] The CCM cutting and transferring module 120 is used to load the CCM material tape 231 , the CCM bottom film material tape 232 and the CCM transfer film material tape 221 , and provide the CCM sheet material 222 to the thermal compounding module 140 .

[0059] like Figure 4As shown, in some embodiments of the present application, the CCM cutting and transfer module 120 includes a CCM unwinding mechanism 121, a CCM bottom film unwinding mechanism 1221, a CCM laminating mechanism 123, a CCM cutting mechanism 124, a CCM peeling mechanism 125, and a CCM transfer film unwinding mechanism 1261. The CCM unwinding mechanism 121 is used to unwind the CCM tape 231, the CCM bottom film unwinding mechanism 1221 is used to unwind the CCM bottom film tape 232, and the CCM laminating mechanism 123 is used to receive the CCM tape 231 and the CCM bottom film tape 232 to form a CCM composite tape 230; the CCM cutting mechanism 124 is used to half-cut the CCM composite tape 230 to form a half-cut CCM tape 233, and the half-cut CCM tape 233 includes a stacked CCM bottom film tape 232 and a CCM sheet 222 (such as Fig.16 The CCM peeling mechanism 125 is located downstream of the CCM cutting mechanism 124 and is used to peel off the CCM sheet 222 to form the semi-cut CCM tape 233; the CCM transfer film unwinding mechanism 1261 is used to unwind the CCM transfer film tape 221, and the CCM transfer film tape 221 is bonded to the CCM sheet 222 to form a CCM semi-cut transfer tape 220.

[0060] Specifically, a lamination roller assembly 1294 is provided downstream of the CCM peeling mechanism 125. The CCM transfer film tape 221 passes through the lamination roller assembly 1294, and the CCM sheet 222 also enters the lamination roller assembly 1294 after being peeled off from the half-cut CCM tape 233. After the lamination action, the CCM sheet 222 adheres to the surface of the CCM transfer film tape 221 to form a CCM half-cut transfer tape 220.

[0061] The CCM bottom film tape 232 is laminated with the CCM tape 231 through the CCM laminating mechanism 123 before the half-cutting process, and the CCM sheet 222 is peeled off through the CCM peeling mechanism 125 after the half-cutting process; the CCM transfer film tape 221 receives the CCM sheet 222 after the half-cutting process, and sends the CCM sheet 222 into the thermal composite module 140 for winding.

[0062] Through this arrangement, the CCM can be cut from a roll to form a sheet, and the CCM transfer film tape 221 is used as a carrier tape to facilitate the next step of feeding the CCM sheet 222 into the thermal composite module 140. During the bonding process of the CCM sheet 222 and the CCM transfer film tape 221, asynchronous transfer is achieved, and the adjacent CCM sheets 222 are pulled apart to obtain a CCM continuous tape with the same pitch as the upper frame sheet 213.

[0063] In other embodiments, according to specific production requirements, the semi-cut CCM strip 233 may be directly loaded, and the semi-cutting process may be completed in advance at other workstations.

[0064] like Figure 4 As shown, in some embodiments thereof, the CCM cutting and transfer module 120 includes a CCM bottom film winding mechanism 1222 and a CCM transfer film winding mechanism 1262, the CCM bottom film winding mechanism 1222 is used to wind up the CCM bottom film strip 232; the CCM transfer film winding mechanism 1262 is used to wind up the CCM transfer film strip 221.

[0065] The CCM bottom film unwinding mechanism 1221 is arranged upstream of the CCM laminating mechanism 123, and the CCM bottom film winding mechanism 1222 is arranged downstream of the CCM peeling mechanism 125. The CCM composite material strip 230 is formed into a half-cut CCM material strip 233 after the half-cutting process, and then peeled to form the CCM sheet material 222. The CCM bottom film material strip 232 is wound up after leaving the CCM peeling mechanism 125.

[0066] The CCM transfer film unwinding mechanism 1261 is arranged upstream of the lamination roller assembly 1294, and the CCM transfer film winding mechanism 1262 is arranged downstream of the thermal composite module 140. The CCM half-cut transfer tape 220 passes through the thermal composite module 140, and the CCM sheet material 222 is attached to the upper frame tape 212. The CCM transfer film tape 221 is wound up after leaving the thermal composite module 140.

[0067] Through this arrangement, the CCM bottom film strip 232 and the CCM transfer film strip 221 can be rolled up.

[0068] Furthermore, the CCM cutting and transferring module 120 also includes a CCM deviation correcting mechanism 1281 , a CCM tape splicing platform 1291 , a CCM bottom film tape splicing platform 1292 and a CCM bottom film deviation correcting mechanism 1293 .

[0069] The CCM unwinding mechanism 121 unwinds the CCM material belt 231, which passes through the CCM deflection correction mechanism 1281 and the CCM tape splicing platform 1291 in sequence before entering the CCM film coating mechanism 123; the CCM bottom film unwinding mechanism 1221 unwinds the CCM bottom film material belt 232, which passes through the CCM bottom film deflection correction mechanism 1293 and the CCM bottom film splicing platform 1292 in sequence before entering the CCM film coating mechanism 123. The axial position of the material belt can be adjusted in time through each deflection correction mechanism, thereby improving the tape running accuracy; the material belt can be spliced ​​when changing rolls through each splicing platform, simplifying the process of changing rolls and splicing.

[0070] like Fig.12 and Fig.13As shown, as an example, the CCM deflection correction mechanism 1281 includes a base plate 1282, a mobile frame 1283, a deflection correction motor 1284, a linear guide 1285 and a ball screw assembly 1286. The mobile frame 1283 is slidably mounted on the base plate 1282 through the linear guide 1285 along the direction X. The mobile frame 1283 is used to load the roller body, and the axial direction of the roller body is parallel to the direction X. The deflection correction motor 1284 is mounted on the base plate 1282 and drives the mobile frame 1283 to move along the direction X through the ball screw assembly 1286. In conjunction with the detection feedback of the corresponding detection mechanism, the deflection correction motor 1284 drives the mobile frame 1283 to move and displace along the direction X, adjusts the position of the roller body along the axial direction of the roller body, and then adjusts the position of the material belt in the direction of the belt width.

[0071] As a preferred implementation, the CCM deviation correction mechanism 1281 can drive the CCM cutting mechanism 124 and the CCM peeling mechanism 125 to move synchronously, thereby improving the cutting and peeling accuracy, and making the CCM sheet 222 and the CCM transfer film tape 221 fit with high precision.

[0072] Furthermore, the CCM cutting and transfer module 120 also includes a CCM vision positioning mechanism 1271 and a cutting vision positioning mechanism 1272 .

[0073] The CCM visual positioning mechanism 1271 is arranged downstream of the CCM peeling mechanism 125, and performs feature recognition on the CCM sheet 222 before the CCM half-cut transfer tape 220 enters the thermal composite module 140, so as to serve as a reference for adjusting the conveying speed of the CCM cutting transfer module 120, thereby accurately controlling the CCM feeding rhythm of the thermal composite module 140.

[0074] The cutting vision positioning mechanism 1272 is disposed upstream of the CCM cutting mechanism 124 and is used to detect the conveying speed of the CCM composite material strip 230 when it enters the CCM cutting mechanism 124, so as to achieve high-precision cutting operations.

[0075] The lower frame cutting and transferring module 130 is used to load the lower frame coil material tape 250 and the lower frame transfer film material tape 241 , and provide the lower frame half-cut transfer material tape 240 to the thermal composite module 140 .

[0076] like Figure 5 As shown, in some embodiments of the present application, the lower frame cutting and transferring module 130 includes a lower frame unwinding mechanism 131, a lower frame cutting mechanism 133, a lower frame peeling mechanism 134 and a lower frame transfer film unwinding mechanism 1351. The lower frame unwinding mechanism 131 is used to unwind the lower frame coiled material strip 250, and the lower frame coiled material strip 250 includes a stacked lower frame bottom film strip 251 and a lower frame strip 252 (such as Fig.16The lower frame cutting mechanism 133 is used to half-cut the lower frame coil material strip 250 to form a lower frame half-cut material strip 253, and the lower frame half-cut material strip 253 includes a stacked lower frame bottom film strip 251 and a lower frame sheet material 242 (as shown in FIG. Fig.16 The lower frame peeling mechanism 134 is located downstream of the lower frame cutting mechanism 133, and is used to peel the lower frame sheet 242 off the lower frame half-cut material belt 253; the lower frame transfer film unwinding mechanism 1351 is used to unwind the lower frame transfer film belt 241, and the lower frame transfer film belt 241 is attached to the lower frame sheet 242 to form the lower frame half-cut transfer belt 240 (as shown in FIG. Fig.16 shown).

[0077] Through this arrangement, the lower frame material strip 252 can be cut into sheets, and the lower frame material strip 252 is fed into the thermal composite module 140 using the lower frame transfer film material strip 241 as a carrier.

[0078] Furthermore, the lower frame material strip 252 is located at the lower side of the lower frame transfer film material strip 241. When entering the thermal composite module 140, the lower frame transfer film material strip 241 is bonded to the pressure roller 142, and the lower frame sheet 242 is located on the outside to facilitate further bonding with the CCM sheet 222 and the upper frame material strip 212.

[0079] It should be noted that, unlike the CCM cutting and transfer module 120, the CCM cutting and transfer module 120 feeds the CCM sheet 222 to the thermal composite module 140, and the CCM transfer film strip 221 leaves the thermal composite module 140 after the CCM sheet 222 is bonded, and does not participate in the thermal composite process; the lower frame cutting and transfer module 130 feeds the thermal composite module 140 with a continuous lower frame half-cut transfer strip 240, and the lower frame transfer film strip 241 participates in the thermal composite process. Through this setting form, it is possible to achieve that the composite strip 200 formed by hot pressing and composite still has a layer of non-product continuous film, and the continuous conveying of the strip can still be maintained after the MEA sheet 300 is formed in the finished product cutting process. And the lower frame transfer film strip 241 is located in the outer layer of the composite strip 200, and will not affect the CCM structure itself when hot pressing and composite forming CCM.

[0080] The lower frame cutting and transfer module 130 also includes corresponding correction mechanisms, a tape connection platform, a tension swing roller, a cutting visual positioning mechanism, a lamination roller assembly, a lower frame visual positioning mechanism 137 and other auxiliary mechanisms, which will not be further elaborated here.

[0081] like Figure 5As shown, further, the lower frame cutting and transferring module 130 includes a lower frame protective film winding mechanism 132, and the lower frame roll material strip 250 includes a stacked lower frame bottom film strip 251, a lower frame strip 252 and a lower frame protective film strip 254, and the lower frame protective film winding mechanism 132 is used to wind up the lower frame protective film strip 254.

[0082] During the unwinding process of the lower frame unwinding mechanism 131, the lower frame protective film rewinding mechanism 132 rewinds the lower frame protective film strip 254, and the lower frame protective film strip 254 is automatically peeled off. In other words, the lower frame coiled material strip 250 entering the lower frame cutting mechanism 133 is essentially the coiled material strip of the lower frame protective film strip 254 that has been peeled off.

[0083] Through this arrangement, the lower frame protective film tape 254 can be rolled up, so as to normally unwind the roll material tape from which the protective film has been peeled off.

[0084] like Figure 5 As shown, in some embodiments of the present application, the lower frame cutting and transfer module 130 also includes a lower frame bottom film winding mechanism 136 and a lower frame transfer film winding mechanism 1352, the lower frame bottom film winding mechanism 136 is used to wind up the lower frame bottom film strip 251, and the lower frame transfer film winding mechanism 1352 is used to wind up the lower frame transfer film strip 241.

[0085] The lower frame bottom film winding mechanism 136 is located downstream of the lower frame peeling mechanism 134, and is wound up after the lower frame cutting and peeling process is completed; the lower frame transfer film winding mechanism 1352 is located downstream of the finished product peeling mechanism 154, and is wound up after the finished product cutting and peeling process is completed.

[0086] Through this arrangement, the lower frame bottom supporting film strip 251 and the lower frame transfer film strip 241 can be rolled up.

[0087] like Figure 6 As shown, in some embodiments of the present application, the upper frame unwinding module 110 includes an upper frame visual positioning mechanism 116, the CCM cutting transfer module 120 includes a CCM visual positioning mechanism 1271, and the lower frame cutting transfer module 130 includes a lower frame visual positioning mechanism 137. The upper frame visual positioning mechanism 116 is located upstream of the thermal composite module 140, and is used to identify the upper frame sheet 213 of the upper frame material belt 212; the CCM visual positioning mechanism 1271 is located upstream of the thermal composite module 140, and is used to identify the CCM sheet 222 of the CCM half-cut transfer material belt 220; the lower frame visual positioning mechanism 137 is located upstream of the thermal composite module 140, and is used to identify the lower frame sheet 242 of the lower frame half-cut transfer material belt 240.

[0088] Specifically, the conveying speed of the CCM half-cut transfer tape 220 and the conveying speed of the lower frame half-cut transfer tape 240 adjust their own speeds based on the conveying speed of the upper frame tape 212. In other words, based on the conveying rhythm of the upper frame sheet 213, the conveying rhythm of the CCM sheet 222 and the lower frame sheet 242 is adjusted in real time to match the conveying rhythm of the upper frame sheet 213, so that the CCM sheet 222 and the lower frame sheet 242 are fitted with the upper frame tape 212, and the contours are matched with the upper frame sheet 213 with high precision.

[0089] Through this arrangement, the feeding rhythms of the three raw materials can be detected separately before entering the thermal composite module 140, and adjustments can be made in real time to achieve asynchronous transfer and bonding of the three raw materials, thereby improving the bonding accuracy.

[0090] The thermal composite module 140 is used to receive the upper frame material strip 212 , the CCM sheet 222 and the lower frame half-cut transfer material strip 240 , and heat-press them to form a composite material strip 200 .

[0091] like Figure 6 As shown, the thermal composite module 140 includes a hot roller 141 and a pressure roller 142. The hot roller 141 is used to receive the upper frame material strip 212 and the CCM sheet material 222, and the pressure roller 142 is used to receive the lower frame half-cut transfer material strip 240. The upper frame material strip 212 attached with the CCM sheet material 222 and the lower frame half-cut transfer material strip 240 enter the gap between the hot roller 141 and the pressure roller 142 together, and the composite material strip 200 (as shown in FIG. 1 ) is formed after hot pressing and laminating. Fig.16 shown).

[0092] In some embodiments of the present application, the thermal composite module 140 also includes an upper frame transition roller 143, a CCM laminating roller 144 and a CCM laminating cylinder 1441. The upper frame transition roller 143 is used to guide the upper frame material strip 212 to be laminated to the hot roller 141, and the CCM laminating cylinder 1441 is used to drive the CCM laminating roller 144 close to the hot roller 141 to laminate the CCM sheet 222 of the CCM half-cut transfer material strip 220 to the upper frame material strip 212.

[0093] The upper frame transition roller 143 and the CCM laminating roller 144 are arranged around the hot roller 141 , and the upper frame transition roller 143 is located upstream of the CCM laminating roller 144 .

[0094] Through this arrangement, the CCM sheet 222 can be attached to the upper frame tape 212, and the CCM transfer film tape 221 is separated from the CCM sheet 222 and then leaves the thermal composite module 140 and is rolled up.

[0095] like Fig.14 and Fig.15As shown, the thermal composite module 140 also includes a hot roller motor 1411, a pressure roller cylinder 1421, a pressure roller motor 1422, an infrared heating device 145, an infrared temperature sensor 146, a pressure sensor 147, a secondary pressure roller 148 and a lower frame guide roller 149.

[0096] The hot roller motor 1411 is used to drive the hot roller 141 to rotate, the pressure roller motor 1422 is used to drive the pressure roller 142 to rotate, and the pressure roller cylinder 1421 is used to drive the pressure roller 142 to approach the hot roller 141 to apply a pressing force; the pressure sensor 147 is used to detect the pressure provided by the pressure roller cylinder 1421 to accurately control the pressing force and provide a suitable pressing force for hot pressing and laminating. The hot roller 141 is a heating steel rod, which is heated by an electric slip ring; the infrared heating device 145 is arranged around the pressure roller 142, and is used to perform infrared heating on the lower frame half-cut transfer tape 240 on the pressure roller 142, and the infrared temperature sensor 146 is used to detect the temperature of the surface of the pressure roller 142, so as to accurately control the material temperature of the lower frame half-cut transfer tape 240 and provide a lower frame half-cut transfer tape 240 with a suitable temperature for hot pressing and laminating. The secondary pressing roller 148 is arranged downstream of the hot pressing position for secondary pressing, and the lower frame guide roller 149 is used to guide the lower frame half-cut transfer tape 240 into the pressing roller 142. This arrangement can improve the hot pressing and laminating quality of the hot laminating module 140.

[0097] like Figure 7 As shown, in some embodiments of the present application, the membrane electrode production equipment 100 further includes a frame cooling module 170 , which is located downstream of the thermal composite module 140 and is used to cool the composite material strip 200 .

[0098] By providing the frame cooling module 170 , the composite material strip 200 can be quickly cooled to facilitate the finished product cutting process and improve the cutting quality.

[0099] like Figure 7 and Figure 8 As shown, the finished product cutting and peeling module 150 includes a finished product cutting mechanism 151, a finished product cutting visual inspection mechanism 152, a finished product correcting mechanism 153 and a finished product peeling mechanism 154. The composite material strip 200 passes through the finished product correcting mechanism 153 and the finished product cutting visual inspection mechanism 152 in sequence and then enters the finished product cutting mechanism 151 to form a half-cut MEA material strip 260, and then passes through the finished product peeling mechanism 154 to output the MEA sheet 300.

[0100] The finished product cutting visual inspection mechanism 152 is used to perform feature recognition on the MEA sheet 300 before the finished product is cut to improve the cutting accuracy.

[0101] The finished product stripping mechanism 154 includes a traction mechanism 1541 and a stripping knife 1542. The traction mechanism 1541 is used to control the material conveying speed, and the stripping knife 1542 is used to strip the half-cut MEA material strip 260 and output the MEA sheet 300. The remaining lower frame transfer film material strip 241 is rolled up after stripping.

[0102] like Figure 8 and Fig. 9 As shown, the lower frame cutting and transferring module 130 includes a winding guide roller 138 , which is arranged at the stripping knife 1542 , and the winding guide roller 138 is used to guide the lower frame transfer film material strip 241 to enter the lower frame transfer film winding mechanism 1352 .

[0103] like Fig.10 and Fig.11 As shown, as an example form, the traction mechanism 1541 includes an active roller 1543, a pressure roller 1544, a pressure cylinder 1547 and an active roller motor 1548. The active roller motor 1548 is used to drive the active roller 1543 to rotate, and the pressure cylinder 1547 is used to drive the pressure roller 1544 to approach the active roller 1543 to provide a pressing force to the material belt. The active roller 1543 rotates to pull the material belt forward for transportation.

[0104] Furthermore, the finished product stripping mechanism 154 also includes a stripping blade moving motor 1545, a handle 1546 and a slide rail assembly 1549. The stripping blade 1542 is slidably mounted on the bracket along the direction X through the slide rail assembly 1549. The stripping blade moving motor 1545 drives the stripping blade 1542 to move along the direction X through the ball screw assembly. The stripping blade 1542 is fixed to a reducer, the reducer is connected to the slide rail assembly 1549 through a bearing, and the handle 1546 is connected to the reducer. The reducer can be rotated by the handle 1546 to adjust the working angle of the stripping blade 1542 to obtain the best stripping angle.

[0105] The stripping knife 1542 has a qualified unloading position and a waste material removal position in the direction X, and cooperates with the corresponding visual recognition mechanism to detect whether the MEA sheet 300 on the half-cut MEA material belt 260 after cutting is qualified. For example, the qualified unloading position is set close to the first conveyor belt 1611 described below, and the waste material removal position is set close to the finished product traction mechanism 1541.

[0106] For qualified MEA sheets 300, the stripping knife 1542 is located at the qualified unloading position for normal stripping, and the stripping forms the MEA sheets 300 for the normal unloading process; for unqualified MEA sheets 300, the stripping knife 1542 moves to the waste removal position, removes the unqualified MEA sheets 300, and the waste falls into the waste collection box on the lower side and will not flow to the next process, thereby improving the quality control accuracy of this link.

[0107] It can be understood that the structures of other peeling mechanisms in this embodiment are substantially the same as the finished product peeling mechanism 154 and will not be further described herein.

[0108] like Figure 8 and Fig. 9 As shown, in some embodiments of the present application, the membrane electrode production equipment 100 also includes a finished product detection and unloading module 160, including a finished product detection mechanism 161 and a finished product unloading mechanism 162. The finished product detection mechanism 161 is located downstream of the finished product stripping mechanism 154, and is used to detect whether the MEA sheet 300 is qualified; the finished product unloading mechanism 162 is used to classify qualified MEA sheets 300 and unqualified MEA sheets 300.

[0109] This arrangement enables the classification of qualified MEA sheets 300 and unqualified MEA sheets 300.

[0110] The finished product inspection mechanism 161 includes a first conveyor belt 1611 and a finished product visual inspection mechanism 1612. The first conveyor belt 1611 is connected to the qualified unloading position of the stripping knife 1542. Qualified MEA sheets 300 fall onto the first conveyor belt 1611. The first conveyor belt 1611 continues to convey the MEA sheets 300. The finished product visual inspection mechanism 1612 is located on the upper side of the first conveyor belt 1611, and inspects the MEA sheets 300 passing through in sequence, and determines qualified MEA sheets 300 and unqualified MEA sheets 300.

[0111] The finished product unloading mechanism 162 includes a second conveyor belt 1621 , an unloading push rod 1622 and a material box assembly 1623 . The material box assembly 1623 includes an NG material box 1624 and an OK material box 1625 . Each material box is equipped with a unloading push rod 1622 .

[0112] The front section of the second conveyor belt 1621 partially overlaps with the rear section of the first conveyor belt 1611, and the front section of the second conveyor belt 1621 is located on the upper side of the rear section of the first conveyor belt 1611. The second conveyor belt 1621 grabs the MEA sheet 300 of the first conveyor belt 1611 by adsorption. The material box assembly 1623 is located on the lower side of the second conveyor belt 1621, and the NG material box 1624 and the OK material box 1625 are arranged at intervals along the conveying direction of the second conveyor belt 1621. If the MEA sheet 300 is a qualified product, the corresponding material discharge push rod 1622 extends to knock down the MEA sheet 300, and the MEA sheet 300 falls into the OK material box 1625; if the MEA sheet 300 is a defective product, the corresponding material discharge push rod 1622 extends to knock down the MEA sheet 300, and the MEA sheet 300 falls into the NG material box 1624.

[0113] As a preferred embodiment, two OK material boxes 1625 are provided, one for use and one for backup, so as to realize non-stop production.

[0114] like Figures 1 to 16 As shown, the working process of the membrane electrode production equipment 100 of the embodiment of the present application is as follows:

[0115] The upper frame unwinding mechanism 111 unwinds the upper frame coil material strip 210, and the upper frame protective film rewinding mechanism 112 rewinds the upper frame protective film strip 211. The upper frame strip 212 is attached to the surface of the hot roller 141 under the guidance of the upper frame transition roller 143.

[0116] The CCM unwinding mechanism 121 unwinds the CCM material strip 231, the CCM bottom film unwinding mechanism 1221 unwinds the CCM bottom film material strip 232, the CCM material strip 231 and the CCM bottom film material strip 232 pass through the CCM laminating mechanism 123 together to form a CCM composite material strip 230, the CCM composite material strip 230 passes through the CCM cutting mechanism 124 to form a half-cut CCM material strip 233, and then passes through the CCM peeling mechanism 125 to peel to form a CCM sheet 222, and the CCM bottom film winding mechanism 1222 winds up the CCM bottom film material strip 232;

[0117] The CCM transfer film unwinding mechanism 1261 unwinds the CCM transfer film tape 221, and the CCM sheet 222 formed by the peeling by the CCM peeling mechanism 125 is attached to the CCM transfer film tape 221 to form a CCM half-cut transfer tape 220;

[0118] Under the pressure of the CCM laminating roller 144, the CCM sheet 222 is attached to the surface of the upper frame material strip 212, and the CCM transfer film material strip 221 leaves the thermal laminating module 140 and is rolled up by the CCM transfer film rolling mechanism 1262;

[0119] The lower frame unwinding mechanism 131 unwinds the lower frame coil material strip 250, and the lower frame protective film rewinding mechanism 132 rewinds the lower frame protective film strip 254. The lower frame coil material strip 250 with the protective film removed passes through the lower frame cutting mechanism 133 and the lower frame peeling mechanism 134 in sequence to form a lower frame sheet 242, and the lower frame bottom film strip 251 is rewinded by the lower frame bottom film rewinding mechanism 136.

[0120] The lower frame transfer film unwinding mechanism 1351 unwinds the lower frame transfer film material strip 241, and the lower frame sheet 242 formed by the peeling of the lower frame peeling mechanism 134 is attached to the lower side of the lower frame transfer film material strip 241 to form a lower frame half-cut transfer material strip 240, which is attached to the surface of the pressure roller 142 under the guidance of the lower frame guide roller 149;

[0121] The upper frame material strip 212 with the CCM sheet 222 attached thereto and the lower frame half-cut transfer material strip 240 are put into between the hot roller 141 and the pressure roller 142 for hot pressing and compounding to form a composite material strip 200;

[0122] After being cooled by the frame cooling module 170, the composite material strip 200 passes through the finished product cutting mechanism 151 and the finished product peeling mechanism 154 in sequence, and the MEA sheet 300 is output. The lower frame transfer film material strip 241 formed by peeling enters the lower frame transfer film winding mechanism 1352 for winding under the guidance of the winding guide roller 138;

[0123] The MEA sheet 300 enters the finished product inspection mechanism 161 to check whether it is a qualified product;

[0124] The MEA sheets 300 enter the finished product unloading mechanism 162 , and the qualified MEA sheets 300 are unloaded into the OK material box 1625 , while the unqualified MEA sheets 300 are unloaded into the NG material box 1624 .

[0125] The use of the membrane electrode production equipment 100 of the embodiment of the present application to prepare MEA sheets 300 reduces the functional integration of the equipment, cancels the online cutting process of the frame film, and reduces the time for coil material change; since the upper frame material strip 212, the CCM sheet material 222 and the lower frame half-cut transfer material strip 240 are fed separately, each module is equipped with a real-time correction function and a visual recognition function, which can perform closed-loop control and improve the stability and control accuracy of the equipment; through the asynchronous transfer bonding method, the continuous material strip is cut into sheets, and then sent to the thermal composite module 140 through the transfer film, which can realize real-time adjustment of production, eliminate bad incoming materials, and make the equipment production more flexible and reliable. The membrane electrode production equipment 100 of the embodiment of the present application adopts a large roller bonding mechanism, integrates CCM bonding and frame film bonding, adds auxiliary heating, and can realize independent control of the conveying rhythm and quality detection of the three, so that the three raw materials entering the thermal composite module 140 are of controllable quality and high-precision bonding, which improves the qualified rate of finished products and quality control accuracy.

[0126] It should be noted that, in the absence of conflict, the features in the embodiments of this application may be combined with each other.

[0127] The above description is only the preferred embodiment of the present application and is not intended to limit the present application.
