Description

Technical Field

[0002] Membrane Electrode Assemblies (MEA) are the core materials of hydrogen fuel cells and need to be packaged during the preparation process, that is, gaskets and films are attached to both sides of the membrane electrode.

[0003] The traditional manufacturing method is sheet lamination, where the membrane electrode, gasket, and film are each made into sheets using a sheeting process. The gasket and film are then attached to the sides of the membrane electrode using a flat pressing method to produce the finished packaged membrane electrode. However, this sheet lamination method has low production efficiency and cannot meet production capacity requirements. Summary of the Invention

[0074] See also Figure 1 The present application provides a packaging device, including a membrane electrode feeding mechanism 1, a first gasket feeding mechanism 2, a first compounding mechanism 3, a first adhesive film feeding mechanism 4, a second compounding mechanism 5, a second gasket feeding mechanism 6, a third compounding mechanism 7, a second adhesive film feeding mechanism 8, a fourth compounding mechanism 9 and a first die-cutting mechanism 91. The membrane electrode feeding mechanism 1 is used to provide a membrane electrode tape b5, that is, to output the membrane electrode tape b5 downstream. The first gasket feeding mechanism 2 is used to provide a first gasket tape, that is, to output the first gasket tape downstream. The first compounding mechanism 3 is arranged downstream of the membrane electrode feeding mechanism 1 and the first gasket feeding mechanism 2, so that the first gasket tape and the membrane electrode tape b5 are both conveyed to the first compounding mechanism 3. The first compounding mechanism 3 is used to press the first gasket tape passing through to the first side e1 of the membrane electrode tape b5, that is, to realize the compounding of the first gasket tape and the membrane electrode tape b5. The first adhesive film feeding mechanism 4 is used to provide the first adhesive film tape. The second laminating mechanism 5 is arranged downstream of the first film feeding mechanism 4 and the first laminating mechanism 3, so that both the first film strip and the membrane electrode strip b5 are fed to the second laminating mechanism 5. The second laminating mechanism 5 is used to press the first film strip passing through onto the first side e1 of the membrane electrode strip b5, thus laminating the first film strip and the membrane electrode strip b5.

[0075] The second gasket feeding mechanism 6 is used to provide the second gasket material strip. The third compounding mechanism 7 is arranged downstream of the second gasket feeding mechanism 6 and the second compounding mechanism 5, so that the membrane electrode material strip b5 and the second gasket material strip are both conveyed to the third compounding mechanism 7. The third compounding mechanism 7 is used to press the passing second gasket material strip onto the first side e1 of the membrane electrode material strip b5, thereby achieving compounding of the second gasket material strip and the membrane electrode material strip b5. The second adhesive film feeding mechanism 8 is used to convey the second adhesive film material strip downstream. The fourth compounding mechanism 9 is arranged downstream of the second adhesive film feeding mechanism 8 and the third compounding mechanism 7, so that the second membrane electrode material strip b5 and the second adhesive film material strip are both conveyed to the fourth compounding mechanism 9. The fourth compounding mechanism 9 is used to press the passing second adhesive film material strip onto the second side e2 of the membrane electrode material strip b5, thereby achieving compounding of the second adhesive film material strip and the membrane electrode material strip b5. The first die-cutting mechanism 91 is arranged downstream of the fourth compounding mechanism 9, and is used to die-cut the passing membrane electrode material strip b5 into membrane electrode sheets.

[0076] In actual use of the above-described packaging equipment, the membrane electrode material strip b5 is first fed by the membrane electrode feeding mechanism 1 to the downstream first laminating mechanism 3. The first gasket feeding mechanism 2 feeds the first gasket material strip to the downstream first laminating mechanism 3. The first laminating mechanism 3 presses the first gasket material strip passing through to the first side e1 of the membrane electrode material strip b5. Then, the membrane electrode material strip b5, after being laminated with the first gasket material strip, is fed to the downstream second laminating mechanism 5. The first adhesive film feeding mechanism 4 feeds the first adhesive film material strip to the downstream second laminating mechanism 5. The second laminating mechanism 5 presses the first adhesive film material strip passing through to the first side e1 of the membrane electrode material strip b5. Then, the membrane electrode material strip b5, after being laminated with the first gasket material strip and the first adhesive film material strip, is fed to the downstream third laminating mechanism 7. The second gasket feeding mechanism 6 feeds the second gasket material strip to the downstream third laminating mechanism 7. The third laminating mechanism 7 presses the second gasket material strip passing through to the second side e2 of the membrane electrode material strip b5. Then, the membrane electrode material strip b5, after being laminated with the first gasket material strip, the first adhesive film material strip, and the second gasket material strip, is conveyed to the downstream fourth laminating mechanism 9. The second adhesive film feeding mechanism 8 conveys the second adhesive film material strip to the downstream fourth laminating mechanism 9, which presses the passing second adhesive film material strip onto the second side e2 of the membrane electrode material strip b5. The membrane electrode material strip b5, after being laminated with the first gasket material strip, the first adhesive film material strip, the second gasket material strip, and the second adhesive film material strip, is then conveyed to the first die-cutting mechanism 91, where the passing membrane electrode material strip b5 is die-cut into membrane electrode sheets.

[0077] In this way, the packaging equipment achieves roll-to-roll continuous lamination of membrane electrode strip b5, first gasket strip, first adhesive film strip, second gasket strip, and second adhesive film strip. The membrane electrode strip b5, after being laminated with the first gasket strip, first adhesive film strip, second gasket strip, and second adhesive film strip, is then die-cut to produce membrane electrode sheets. Compared to the prior art method of laminating sheets, the roll-to-roll continuous lamination method employed in this application significantly improves production efficiency and can better meet production capacity requirements.

[0078] Specifically, in this embodiment, the membrane electrode strip b5 conveyed by the membrane electrode feeding mechanism 1 includes a first support film c5, a membrane electrode layer d12, and a second support film c8, which are stacked in sequence. The membrane electrode layer d12 includes multiple membrane electrode units spaced apart along the length of the second support film c8. Each membrane electrode unit includes a first frame d1, a CCM d3, and a second frame d4, which are stacked in sequence. The first side e1 of the membrane electrode strip b5 refers to the side with the first support film c5, and the second side e2 of the membrane electrode strip b5 refers to the side with the second support film c8.

[0079] The packaging equipment also includes a first winding mechanism a1, which is arranged between the downstream of the membrane electrode feeding mechanism 1 and the upstream of the first laminating mechanism 3. The first winding mechanism a1 is used to wind up the first base film c5 of the membrane electrode strip b5 passing through, so that when the first laminating mechanism 3 and the second laminating mechanism 5 respectively laminate the first gasket strip and the first adhesive film strip to the first side e1 of the membrane electrode strip b5, the first gasket strip and the first adhesive film strip can be attached to the first frame d1 of the membrane electrode unit of the membrane electrode strip b5.

[0080] Specifically in the embodiment, the packaging device further includes a second winding mechanism a2, which is arranged between the downstream of the second laminating mechanism 5 and the upstream of the third laminating mechanism 7. The second winding mechanism a2 is used to wind up the second base film c8 of the membrane electrode material strip b5 passing through, so that when the third laminating mechanism 7 and the fourth laminating mechanism 9 subsequently laminate the second gasket material strip and the second adhesive film material strip to the second side e2 of the membrane electrode material strip b5, respectively, the second gasket material strip and the second adhesive film material strip can be attached to the second frame d4 of the membrane electrode unit of the membrane electrode material strip b5.

[0081] Specifically, in this embodiment, the first film strip delivered by the first film feeding mechanism 4 includes a third backing film c13 and a plurality of first film portions d8 laminated on one side of the third backing film c13. The plurality of first film portions d8 are arranged at intervals along the length of the first film strip. The second film strip delivered by the second film feeding mechanism 8 includes a fourth backing film c17 and a plurality of second film portions d11 laminated on one side of the fourth backing film c17. The plurality of second film portions d11 are arranged at intervals along the length of the second film strip.

[0082] The packaging equipment also includes a third winding mechanism a3, which is arranged between the downstream of the fourth laminating mechanism 9 and the upstream of the first die-cutting mechanism 91. The third winding mechanism a3 is used to wind the third support film c13 of the first adhesive film strip that is laminated with the membrane electrode strip b5, allowing the first die-cutting mechanism 91 to cut the passing membrane electrode strip b5, thereby preventing the first die-cutting mechanism 91 from cutting the third support film c13. It can be understood that the first die-cutting mechanism 91 cuts the membrane electrode strip b5 into membrane electrode sheets containing a single membrane electrode unit without die-cutting the fourth support film c17, ensuring that the die-cut membrane electrode sheet is carried on the fourth support film c17 and continues to be transported downstream along with the fourth support film c17.

[0083] Specifically in the embodiment, the packaging device also includes a fourth winding mechanism a4, which is arranged downstream of the first die-cutting mechanism 91 and is used to wind up the fourth supporting film c17 of the second adhesive film strip passing through, so that the membrane electrode sheet is separated from the fourth supporting film c17.

[0084] Furthermore, the packaging apparatus includes a conveying mechanism 92, which is arranged downstream of the first die-cutting mechanism 91 and is used to receive the membrane electrode sheet separated from the fourth support film c17 and convey the membrane electrode sheet downstream. Optionally, the conveying mechanism 92 can be a vacuum belt conveyor that can absorb and fix the membrane electrode sheet and convey it downstream. At the same time, the fourth winding mechanism a4 winds up the fourth support film c17, gradually separating the membrane electrode sheet from the fourth support film c17.

[0085] See Figure 1 and Figure 2 In an embodiment of the present application, the first gasket feeding mechanism 2 includes a first gasket unwinding assembly 21 and a first release film winding assembly 23. The first gasket unwinding assembly 21 is used to unwind and output the first initial gasket tape c11 to the first composite mechanism 3. The first initial gasket tape c11 unwound by the first gasket unwinding assembly 21 includes a first release film and a plurality of first gaskets d7 arranged on one side of the first release film, and the plurality of first gaskets d7 are arranged at intervals along the length direction of the first release film. The first release film winding assembly 23 is used to wind up the first release film of the first initial gasket tape c11 on the upstream side of the first composite mechanism 3, so that the first gasket d7 of the first initial gasket tape c11 enters the first composite mechanism 3 after being separated from the first release film, and then the first composite mechanism 3 presses the first gasket d7 onto the first frame d1 of the membrane electrode unit of the membrane electrode tape b5.

[0086] Furthermore, the first gasket feeding mechanism 2 also includes a fifth pair of rollers 24 and a first waste edge winding assembly 22. The fifth pair of rollers 24 is arranged between the downstream of the first gasket unwinding assembly 21 and the upstream of the first composite mechanism 3. The first waste edge winding assembly 22 is arranged downstream of the fifth pair of rollers 24, so that after the first initial gasket material strip c11 unwound and output by the first gasket unwinding assembly 21 passes through the fifth pair of rollers 24, the waste edge of the first initial gasket material strip c11 is wound up by the first waste edge winding assembly 22, so that the waste edge of the first initial gasket material strip c11 entering the first composite mechanism 3 has been removed, thereby preventing the waste edge from affecting the fitting of the first gasket d7 and the first frame d1 of the membrane electrode unit.

[0087] See Figure 1 and Figure 3 In an embodiment of the present application, the first adhesive film feeding mechanism 4 includes a third support film unwinding assembly 41, a first die-cutting assembly 42, a first mask winding assembly 43, a first composite assembly 44, and a first adhesive film unwinding assembly 45. The third support film unwinding assembly 41 is used to unwind and output the third support film c13 to the first die-cutting assembly 42, and the first mask is laminated on one side of the third support film c13. The first die-cutting assembly 42 is used to die-cut the first mask on the third support film c13 (the first mask is die-cut to form the first mask portion d6 and waste), that is, the first die-cutting assembly 42 only die-cuts the first mask, and does not die-cut the third support film c13. The first mask winding assembly 43 is arranged downstream of the first die-cutting assembly 42 and is used to wind up the waste formed by the die-cutting of the first mask, so that the first mask portion d6 formed by the die-cutting of the first mask by the first die-cutting assembly 42 remains on the third support film c13. The first composite assembly 44 is positioned downstream of the first die-cutting assembly 42 and upstream of the second composite mechanism 5. The first film unwinding assembly 45 is configured to unwind the first initial film strip c14 toward the first composite assembly 44, ensuring that both the first initial film strip c14 and the die-cut third backing film c13 are delivered to the first composite assembly 44. While passing through the first composite assembly 44, the first initial film strip c14 is positioned on the side of the third backing film c13 having the first masking portion d6. The first composite assembly 44 is configured to press the first initial film strip c14 onto the side of the third backing film c13 having the first masking portion d6.

[0088] Furthermore, the first film feeding mechanism 4 also includes a second die-cutting assembly 46, a first pair of rollers 47, a first row of waste tape unwinding assembly 48, and a first row of waste tape rewinding assembly 49. The second die-cutting assembly 46 is positioned downstream of the first laminating assembly 44, allowing the first initial film web c14 to enter the second die-cutting assembly 46 after being laminated with the third backing film c13. The second die-cutting assembly 46 is used to die-cut the first initial film web c14 passing through it, thereby die-cutting the first initial film web c14 into the first film d8 and waste film. The first pair of rollers 47 is positioned downstream of the second die-cutting assembly 46 and upstream of the second laminating mechanism 5. The first row of waste tape unwinding assembly 48 is used to unwind and output the first row of waste tape c15 to the first pair of roller assemblies 47, so that the third base film c13, the first initial film material strip c14 and the first row of waste tape c15 are all conveyed to the first pair of roller assemblies 47, and the first row of waste tape c15 is located on the side of the third base film c13 that is adhered to the first initial film material strip c14, so that the first row of waste tape c15 sticks to the waste material formed after the first initial film material strip c14 is die-cut. The first-row waste tape reel assembly 49 is positioned downstream of the first pair of roller assemblies 47 and is used to reel in the first row of waste tape c15, allowing the waste portion of the first initial film strip c14 to be reeled along with the first row of waste tape c15. The first film d8 formed by die-cutting the first initial film strip c14 remains attached to the third backing film c13. In other words, the first film strip provided to the second laminating mechanism 5 includes the third backing film c13 and the first masking portion d6 and first film d8 attached to the same side of the third backing film c13. The second laminating mechanism 5 is used to press the first film d8 of the first film strip onto the first frame d1 of the membrane electrode unit of the membrane electrode strip b5.

[0089] See Figure 1 and Figure 4 In an embodiment of the present application, the second gasket feeding mechanism 6 includes a second gasket unwinding assembly 61 and a second release film winding assembly 63. The second gasket unwinding assembly 61 is used to unwind and output the second initial gasket tape c16 to the third composite mechanism 7. The second initial gasket tape c16 unwound by the second gasket unwinding assembly 61 includes a second release film and a plurality of second gaskets d10 arranged on one side of the second release film, and the plurality of second gaskets d10 are arranged at intervals along the length direction of the second release film. The second release film winding assembly 63 is used to wind up the second release film of the second initial gasket tape c16 on the upstream side of the second composite mechanism 5, so that the second gasket d10 of the second initial gasket tape c16 enters the third composite mechanism 7 after being separated from the second release film, and then the third composite mechanism 7 presses the second gasket d10 onto the second frame d4 of the membrane electrode unit of the membrane electrode tape b5.

[0090] Furthermore, the second gasket feeding mechanism 6 also includes a sixth pair of rollers 64 and a second waste edge winding assembly 62. The sixth pair of rollers 64 is arranged between the downstream of the second gasket unwinding assembly 61 and the upstream of the third composite mechanism 7. The second waste edge winding assembly 62 is arranged downstream of the sixth pair of rollers 64, so that after the second initial gasket material strip unwound by the second gasket unwinding assembly 61 passes through the sixth pair of rollers 64, the waste edge of the second initial gasket material strip is wound by the second waste edge winding assembly 62, so that the waste edge of the second initial gasket material strip entering the third composite mechanism 7 has been removed, thereby preventing the waste edge from affecting the bonding of the second gasket d10 and the membrane electrode unit.

[0091] See Figure 1 and Figure 5 In the embodiment of the present application, the second film feeding mechanism 8 includes a fourth support film unwinding assembly 81, a ninth die-cutting assembly 82, a second mask rewinding assembly 83, a second composite assembly 84, and a second film unwinding assembly 85. The fourth support film unwinding assembly 81 is used to unwind and output the fourth support film C17 to the second die-cutting assembly 46. The fourth support film C17 has a second mask disposed on one side. The ninth die-cutting assembly 82 is used to die-cut the second mask on the fourth support film C17. That is, the ninth die-cutting assembly 82 only die-cuts the second mask and does not die-cut the fourth support film C17. The second mask rewinding assembly 83 is arranged downstream of the ninth die-cutting assembly 82 and is used to rewind the second mask on the fourth support film C17. This ensures that the second mask portion d9 formed by the ninth die-cutting assembly 82 remains on the fourth support film C17, while the remaining portion of the second mask is rewound by the second mask rewinding assembly 83. The second composite assembly 84 is positioned downstream of the ninth die-cutting assembly 82 and upstream of the fourth composite mechanism 9. The second film unwinding assembly 85 unwinds the second initial film strip c18 to the second composite assembly 84, ensuring that both the second initial film strip c18 and the die-cut fourth backing film c17 are delivered to the second composite assembly 84. While passing through the second composite assembly 84, the second initial film strip c18 is positioned on the side of the fourth backing film c17 with the second masking portion d9. The second composite assembly 84 is configured to press the passing second initial film strip c18 onto the side of the fourth backing film c17 with the second masking portion d9.

[0092] Furthermore, the second film feeding mechanism 8 also includes a third die-cutting assembly 86, a second pair of rollers 87, a second row of waste tape unwinding assembly 88, and a second row of waste tape rewinding assembly 89. The third die-cutting assembly 86 is positioned downstream of the second laminating assembly 84. After laminating the second initial film strip c18 with the fourth backing film c17, it enters the third die-cutting assembly 86. This third die-cutting assembly 86 is used to die-cut the second initial film strip c18 as it passes through. The second pair of rollers 87 is positioned downstream of the third die-cutting assembly 86 and upstream of the fourth laminating mechanism 9. The second row of waste tape unwinding assembly 88 is used to unwind and output the second row of waste tape c19 to the second pair of roller assemblies 87, so that the fourth base film c17, the second initial film material strip c18 and the second row of waste tape c19 are all transported to the second pair of roller assemblies 87, and the second row of waste tape c19 is located on the side of the fourth base film c17 to which the second initial film material strip c18 is attached, so that the second row of waste tape c19 sticks to the waste material formed after the second initial film material strip c18 is die-cut. The second-row waste tape reel assembly 89 is positioned downstream of the second pair of roller assemblies 87 and is used to reel in the second row of waste tape c19, allowing the waste portion of the second initial film strip c18 to be reeled along with the second row of waste tape c19. The second film d11 formed by die-cutting the second initial film strip c18 remains adhered to the third backing film c13. In other words, the second film strip provided to the fourth laminating mechanism 9 includes the fourth backing film c17 and the second masking portion d9 and second film d11 adhered to the same side of the fourth backing film c17. The fourth laminating mechanism 9 is used to press-bond the second film d11 of the second film strip to the second frame d4 of the membrane electrode unit of the membrane electrode strip b5.

[0093] See Figure 1 and Figure 6 In the embodiment of the present application, the membrane electrode feeding mechanism 1 includes a CCM feeding assembly 11, a first frame feeding assembly 12, a second frame feeding assembly 13 and a fifth composite mechanism 14. The CCM feeding assembly 11, the first frame feeding assembly 12 and the second frame feeding assembly 13 are respectively used to unwind and output the CCM material tape, the first frame material tape and the second frame material tape to the fifth composite mechanism 14. The fifth composite mechanism 14 is used to press the first frame material tape and the second frame material tape to the two sides of the CCM material tape, so that the first frame material tape, the CCM material tape and the second frame material tape are stacked in sequence to form the above-mentioned membrane electrode material tape b5, that is, the membrane electrode material tape b5 is produced by a roll-to-roll continuous composite method, which greatly improves production efficiency and can better meet production capacity requirements.

[0094] Specifically in the embodiment, the fifth composite mechanism 14 includes a primary composite component 141 and a secondary composite component 143. The primary composite component 141 is arranged downstream of the CCM feeding component 11 and the first frame feeding component 12, so that the CCM feeding component 11 and the first frame feeding component 12 respectively convey the CCM material strip and the first frame material strip to the primary composite component 141. The primary composite component 141 is used to press the CCM material strip and the first frame material strip passing through. The secondary composite component 143 is arranged downstream of the primary composite component 141 and the second frame feeding component 13, so that the composite material strip formed by pressing the CCM material strip and the first frame material strip is conveyed from the primary composite component 141 to the secondary composite component 143, and the second frame feeding component 13 conveys the second frame material strip to the secondary composite component 143. The secondary composite assembly 143 is used to press the composite material strips (i.e., the CCM material strip and the first frame material strip) and the second frame material strip passing through, thereby forming a membrane electrode material strip b5 which is sequentially stacked by the first frame material strip, the CCM material strip and the second frame material strip.

[0095] Specifically, in the embodiment, the CCM feeding assembly 11 includes a CCM unwinding assembly 111, a fourth die-cutting assembly 114, and a CCM waste edge rewinding assembly 115. The CCM unwinding assembly 111 is used to unwind and output the initial CCM material strip c1 to the fourth die-cutting assembly 114. The initial CCM material strip c1 unwound and output by the CCM unwinding assembly 111 includes a fifth backing film and a CCM layer stacked on one side of the fifth backing film. The fourth die-cutting assembly 114 is used to die-cut the CCM layer of the initial CCM material strip c1 passing through, so that the CCM layer is die-cut to form a plurality of CCMs d3 arranged along the length direction of the fifth backing film. The CCM waste edge rewinding assembly 115 is arranged downstream of the fourth die-cutting assembly 114 and is used to rewind the waste edge formed by die-cutting the CCM layer of the initial CCM material strip c1.

[0096] Furthermore, the CCM feeding assembly 11 also includes a third composite assembly 113, a cutting film unwinding assembly 112, and a cutting film rewinding assembly 116. The third composite assembly 113 is positioned downstream of the CCM unwinding assembly 111 and upstream of the fourth die-cutting assembly 114, so that the initial CCM strip c1 unwound by the CCM unwinding assembly 111 passes sequentially through the third composite assembly 113, the fourth die-cutting assembly 114, and the primary composite assembly 141 of the fifth composite mechanism 14. The cutting film unwinding assembly 112 is positioned upstream of the third composite assembly 113 and is configured to unwind a cutting film c2 to the third composite assembly 113, so that the third composite assembly 113 composites the cutting film c2 with the initial CCM strip c1 (the cutting film c2 is laminated on the side of the fifth backing film facing away from the CCM layer). This strengthens the composite strip's hardness and helps improve the die-cutting quality of the initial CCM strip passed by the fourth die-cutting assembly 114. The cut film winding assembly 116 is arranged downstream of the fourth die-cutting assembly 114 and is used to wind up the cut film c2 to prevent the cut film c2 from continuing to be transported downstream following the initial CCM material strip c1.

[0097] Furthermore, the CCM feeding assembly 11 also includes a first roller, a first transfer film unwinding assembly 117, and a first transfer film winding assembly 118. The first roller is positioned downstream of the fourth die-cutting assembly 114 and upstream of the primary laminating assembly 141. The first transfer film unwinding assembly 117 is configured to unwind the first transfer film c4 onto the first roller, allowing the initial CCM strip c1 and the first transfer film c4 to be wound together through the first roller, thereby laminating the initial CCM strip c1 and the first transfer film c4 together (the first transfer film c4 is laminated on the side of the fifth backing film facing away from the CCM layer). The first transfer film c4 is then used to adjust the unwinding speed of the initial CCM strip c1. The first transfer film winding assembly 118 is arranged on the downstream side of the primary lamination assembly 141, and is used to wind up the first transfer film c4 and the fifth backing film, so that the CCM layer of the initial CCM material strip c1 is separated from the first transfer film c4 and the fifth backing film, and the CCM layer of the initial CCM material strip c1 and the first frame material strip are pressed together by the primary lamination assembly 141.

[0098] In an embodiment of the present application, the first frame feeding assembly 12 includes a first base film unwinding assembly 121, a first frame unwinding assembly 125, a fifth die-cutting assembly 126, a third pair of rollers 127, a third row of waste tape unwinding assembly 128, and a third row of waste tape rewinding assembly 129. The first base film unwinding assembly 121 and the first frame unwinding assembly 125 are respectively configured to unwind and output the first base film c5 and the first initial frame material strip c6 to the fifth die-cutting assembly 126. The fifth die-cutting assembly 126 is configured to die-cut the first initial frame material strip c6 passing through it, so that the first initial frame material strip c6 is cut to form a plurality of first frames d1 arranged along the length direction of the first base film c5. The third pair of rollers 127 is arranged between the downstream of the fifth die-cutting assembly 126 and the upstream of the primary composite assembly 141, and the third row of waste tape unwinding assembly 128 is arranged upstream of the third pair of rollers 127, and is used to unwind the third row of waste tape c7 to the third pair of rollers 127, so that the first initial frame material tape c6, the first base film c5 and the third row of waste tape c7 pass through the third pair of rollers 127 together, and the third row of waste tape c7 is stacked on the side of the first initial frame material tape c6 away from the first base film c5, so that the third pair of rollers 127 presses the third row of waste tape c7 onto the first initial frame material tape c6, ensuring that the third row of waste tape c7 sticks to the waste material formed by die-cutting of the first initial frame material tape c6. The third row of waste tape winding assembly 129 is arranged downstream of the third pair of rollers assembly 127, and is used to wind up the third row of waste tape c7, so that the waste formed by die-cutting the first initial frame material tape c6 is wound together with the third row of waste tape c7, and the first frame d1 formed by die-cutting the first initial frame material tape c6 is adhered to the first base film c5 and follows the first base film c5 into the primary composite assembly 141.

[0099] Furthermore, a third release film is laminated on one side of the first initial frame material strip c6 unwound by the first frame unwinding assembly 125. This third release film is located on the side of the first initial frame material strip c6 facing away from the first base film c5. The third row waste tape rewinding assembly 129 is used to rewind the third row of waste tape c7 and the third release film, thereby preventing the third release film from adversely affecting subsequent material strip lamination.

[0100] Furthermore, the first frame feeding assembly 12 also includes a seventh pair of rollers. This seventh pair of rollers is located downstream of the first base film unwinding assembly 121 and the first frame unwinding assembly 125, and upstream of the fifth die-cutting assembly 126. This ensures that the first base film c5 and the first initial frame material strip c6, respectively unwound by the first base film unwinding assembly 121 and the first frame unwinding assembly 125, are conveyed to the seventh pair of rollers. This seventh pair of rollers is used to laminate the first base film c5 and the first initial frame material strip c6 as they pass through.

[0101] Specifically in the embodiment, a third mask is stacked on one side of the first support film c5 unwound by the first support film unwinding assembly 121, and the third mask is located on the side of the first support film c5 that is bonded to the first initial frame material strip c6. The first frame feeding assembly 12 also includes a sixth die-cutting assembly 122 and a third mask winding assembly 123. The sixth die-cutting assembly 122 is arranged between the downstream of the first support film unwinding assembly 121 and the upstream of the fifth die-cutting assembly 126, and is used to die-cut the third mask on the first support film c5 passing through, so that the third mask is cut to form a plurality of third mask portions d2 arranged along the length direction of the first support film c5. The third mask winding assembly 123 is arranged downstream of the sixth die-cutting assembly 122, and is used to wind up the waste formed by die-cutting the third mask, so that the third mask portion d2 formed by die-cutting continues to be bonded to the first support film c5. In this way, when the primary composite component 141 presses the CCM tape passing by with the first frame tape, the CCMd3 on the CCM tape is pressed onto the first frame d2 on the first frame tape.

[0102] In an embodiment of the present application, the second frame feeding assembly 13 includes a second base film unwinding assembly 131, a second frame unwinding assembly 135, a seventh die-cutting assembly 136, a fourth pair of rollers, a fourth row of waste tape unwinding assembly 137, and a fourth row of waste tape rewinding assembly 138. The second base film unwinding assembly 131 and the second frame unwinding assembly 135 are respectively used to unwind and output the second base film c8 and the second initial frame material strip c9 to the seventh die-cutting assembly 136. The seventh die-cutting assembly 136 is used to die-cut the second initial frame material strip c9 passing through, so that the second initial frame material strip c9 is cut to form a plurality of second frames d4 arranged along the length direction of the second base film c8. The fourth pair of rollers is arranged between the downstream of the seventh die-cutting assembly 136 and the upstream of the secondary composite assembly 143, and the fourth row of waste tape unwinding assembly 137 is arranged upstream of the fourth pair of rollers, for unwinding the fourth row of waste tape c10 to the fourth pair of rollers, so that the second initial frame material tape c9, the second base film c8 and the fourth row of waste tape c10 pass through the fourth pair of rollers together, and the fourth row of waste tape c10 is stacked on the side of the second initial frame material tape c9 away from the second base film c8, so that the fourth pair of rollers presses the fourth row of waste tape c10 onto the second initial frame material tape c9, ensuring that the fourth row of waste tape c10 sticks to the waste material formed by die-cutting the second initial frame material tape c9. The fourth row of waste tape winding assembly 138 is arranged downstream of the fourth pair of roller assemblies, and is used to wind up the fourth row of waste tape c10, so that the waste material formed by die-cutting the second initial frame material tape c9 is wound together with the fourth row of waste tape c10, and the second frame d4 formed by die-cutting the second initial frame material tape c9 is adhered to the second base film c8 and follows the second base film c8 into the secondary composite assembly 143.

[0103] Furthermore, a fourth release film is laminated on one side of the second initial frame material strip c9 unwound by the second frame unwinding assembly 135. This fourth release film is located on the side of the second initial frame material strip c9 facing away from the second base film c8. The fourth row waste tape rewinding assembly 138 is used to rewind the fourth row of waste tape c10 and the fourth release film, thereby preventing the fourth release film from adversely affecting subsequent material lamination.

[0104] Furthermore, the second frame feeding assembly 13 also includes an eighth pair of rollers 134. The eighth pair of rollers 134 is located downstream of the second base film unwinding assembly 131 and the second frame unwinding assembly 135, and upstream of the seventh die-cutting assembly 136. This allows the second base film c8 and the second initial frame material strip c9, respectively unwound by the second base film unwinding assembly 131 and the second frame unwinding assembly 135, to be conveyed together to the eighth pair of rollers 134. The eighth pair of rollers 134 is used to press the second base film c8 and the second initial frame material strip c9 as they pass through.

[0105] Specifically in the embodiment, a fourth mask is stacked on one side of the second support film c8 unwound by the second support film unwinding assembly 131, and the fourth mask is located on the side of the second support film c8 that is bonded to the second initial frame material strip c9. The second frame feeding assembly 13 also includes an eighth die-cutting assembly 133 and a fourth mask winding assembly 132. The eighth die-cutting assembly 133 is arranged between the downstream of the second support film unwinding assembly 131 and the upstream of the seventh die-cutting assembly 136, and is used to die-cut the fourth mask on the second support film c8 passing through, so that the fourth mask is cut to form a plurality of fourth mask portions d5 arranged along the length direction of the second support film c8. The fourth mask winding assembly 132 is arranged downstream of the eighth die-cutting assembly 133, and is used to wind up the fourth mask (i.e., wind up the other parts of the fourth mask except the fourth mask portion d5), so that the fourth mask portion d5 formed by die-cutting continues to be bonded to the second support film c8.

[0106] In this way, when the secondary composite assembly 143 presses the CCM strip passing through it onto the second frame strip, the CCMd3 on the CCM strip is pressed onto the second frame d4 on the second frame strip, thereby forming a membrane electrode strip b5 in which the first frame strip, the CCM strip, and the second frame strip are stacked in sequence. The membrane electrode strip b5 includes multiple membrane electrodes d12 arranged along its length. Each membrane electrode d12 includes a CCMd3 and a first frame d1 and a second frame d4 stacked on either side of the CCMd3. The first mask portion d2 is used to protect the area of ​​the CCMd3 not covered by the first frame d1, and the second mask portion d5 is used to protect the area of ​​the CCMd3 not covered by the second frame d4.

[0107] Based on the above packaging device, this application also provides a packaging method. Figure 1 and Figure 7 , the packaging method comprises the following steps:

[0108] S10, using the membrane electrode feeding mechanism 1 to prepare the membrane electrode strip b5;

[0109] S20, using the membrane electrode feeding mechanism 1 to output the membrane electrode material strip b5, using the first gasket feeding mechanism 2 to output the first gasket material strip, and using the first compounding mechanism 3 to press the first gasket material strip onto the first side e1 of the membrane electrode material strip b5;

[0114] In this way, continuous roll-to-roll lamination of the membrane electrode strip b5, the first gasket strip, the first adhesive film strip, the second gasket strip, and the second adhesive film strip is achieved. The membrane electrode strip b5, after being laminated with the first gasket strip, the first adhesive film strip, the second gasket strip, and the second adhesive film strip, is then die-cut to produce a membrane electrode sheet. Compared to the prior art method of laminating sheets, the roll-to-roll continuous lamination method employed in this application significantly improves production efficiency and can better meet production capacity requirements.

[0115] Specifically in the embodiment, step S10 includes: a CCM processing step, a first frame processing step, a CCM and first frame composite step, a second frame processing step, and a CCM and second frame composite step.

The first composite strip b1 includes the fifth backing film, the first transfer film c4 laminated on one side of the fifth backing film, and the CCM d3 laminated on the other side of the fifth backing film.

[0130] S127. Use the third row of waste tape winding assembly 129 to wind up the third row of waste tape c7 and the third release film, thereby forming a second composite material strip b2 (i.e., the above-mentioned first frame material strip) including the first base film c5 and the first frame d1 and the third mask part d2 attached to the same side of the first base film c5.
