Technical Field

[0002] Membrane Electrode Assemblies (MEAs) are the core materials of hydrogen fuel cells. They need to be encapsulated during the manufacturing process, which involves attaching gaskets and films to both sides of the MEA.

[0003] The traditional manufacturing method is sheet-and-film lamination, where the membrane electrode, gasket, and adhesive film are each fabricated into sheets using a sheet-making process.

However, this sheet-and-film lamination method has low production efficiency and cannot meet capacity demands. Summary of the Invention

[0032] Please see Figure 1This application provides an encapsulation device, including a membrane electrode feeding mechanism 1, a first gasket feeding mechanism 2, a first composite mechanism 3, a first adhesive film feeding mechanism 4, a second composite mechanism 5, a second gasket feeding mechanism 6, a third composite mechanism 7, a second adhesive film feeding mechanism 8, a fourth composite mechanism 9, and a first die-cutting mechanism 91. The membrane electrode feeding mechanism 1 provides membrane electrode strip b5, i.e., outputs membrane electrode strip b5 downstream. The first gasket feeding mechanism 2 provides first gasket strip, i.e., outputs first gasket strip downstream. The first composite mechanism 3 is arranged downstream of the membrane electrode feeding mechanism 1 and the first gasket feeding mechanism 2, such that both the first gasket strip and the membrane electrode strip b5 are conveyed to the first composite mechanism 3. The first composite mechanism 3 is used to press the passing first gasket strip onto the first side e1 of the membrane electrode strip b5, i.e., to achieve the composite of the first gasket strip and the membrane electrode strip b5. The first adhesive film feeding mechanism 4 provides the first adhesive film strip. The second composite mechanism 5 is located downstream of the first adhesive film feeding mechanism 4 and the first composite mechanism 3, so that both the first adhesive film strip and the membrane electrode strip b5 are fed to the second composite mechanism 5. The second composite mechanism 5 is used to press the passing first adhesive film strip onto the first side e1 of the membrane electrode strip b5, thereby realizing the composite of the first adhesive film strip and the membrane electrode strip b5.

[0033] The second gasket feeding mechanism 6 provides the second gasket strip. The third composite mechanism 7 is located downstream of the second gasket feeding mechanism 6 and the second composite mechanism 5, such that both the membrane electrode strip b5 and the second gasket strip are fed to the third composite mechanism 7. The third composite mechanism 7 presses the passing second gasket strip onto the first side e1 of the membrane electrode strip b5, thus achieving the composite of the second gasket strip and the membrane electrode strip b5. The second adhesive film feeding mechanism 8 feeds the second adhesive film strip downstream. The fourth composite mechanism 9 is located downstream of the second adhesive film feeding mechanism 8 and the third composite mechanism 7, such that both the membrane electrode strip b5 and the second adhesive film strip are fed to the fourth composite mechanism 9. The fourth composite mechanism 9 presses the passing second adhesive film strip onto the second side e2 of the membrane electrode strip b5, thus achieving the composite of the second adhesive film strip and the membrane electrode strip b5. The first die-cutting mechanism 91 is located downstream of the fourth composite mechanism 9 and is used to die-cut the passing membrane electrode strip b5 into membrane electrode sheets.

[0034] In actual use, the aforementioned packaging equipment operates as follows: First, the membrane electrode feeding mechanism 1 feeds the membrane electrode strip b5 to the downstream first composite mechanism 3, and the first gasket feeding mechanism 2 feeds the first gasket strip to the downstream first composite mechanism 3. The first composite mechanism 3 presses the passing first gasket strip onto the first side e1 of the membrane electrode strip b5. Then, the membrane electrode strip b5, after being composited with the first gasket strip, is fed to the downstream second composite mechanism 5. The first adhesive film feeding mechanism 4 feeds the first adhesive film strip to the downstream second composite mechanism 5, and the second composite mechanism 5 presses the passing first adhesive film strip onto the first side e1 of the membrane electrode strip b5. Next, the membrane electrode strip b5, after being composited with the first gasket strip and the first adhesive film strip, is fed to the downstream third composite mechanism 7. The second gasket feeding mechanism 6 feeds the second gasket strip to the downstream third composite mechanism 7, and the third composite mechanism 7 presses the passing second gasket strip onto the second side e2 of the membrane electrode strip b5. Next, the membrane electrode strip b5, after being combined with the first gasket strip, the first adhesive film strip, and the second gasket strip, is conveyed to the downstream fourth composite mechanism 9. The second adhesive film feeding mechanism 8 conveys the second adhesive film strip to the downstream fourth composite mechanism 9, and the fourth composite mechanism 9 presses the passing second adhesive film strip onto the second side e2 of the membrane electrode strip b5. The membrane electrode strip b5, after being combined with the first gasket strip, the first adhesive film strip, the second gasket strip, and the second adhesive film strip, is then conveyed to the first die-cutting mechanism 91, where the passing membrane electrode strip b5 is die-cut into membrane electrode sheets.

[0035] Thus, the aforementioned packaging equipment enables continuous roll-to-roll lamination production 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. The laminated membrane electrode strip b5 is then die-cut to obtain the membrane electrode sheet. Compared to the sheet lamination method used in existing technologies, the roll-to-roll continuous lamination method in this application significantly improves production efficiency and better meets capacity requirements.

[0036] Specifically, in this embodiment, the membrane electrode feeding mechanism 1 conveys a membrane electrode strip b5 comprising a first support film c5, a membrane electrode layer d12, and a second support film c8 stacked sequentially. The membrane electrode layer d12 includes a plurality of 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 stacked sequentially. 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.

[0037] 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 composite mechanism 3. The first winding mechanism a1 is used to wind up the first support film c5 of the membrane electrode strip b5, so that when the first composite mechanism 3 and the second composite mechanism 5 respectively composite 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.

[0038] In a specific embodiment, the packaging device further includes a second winding mechanism a2, which is arranged between the downstream of the second composite mechanism 5 and the upstream of the third composite mechanism 7. The second winding mechanism a2 is used to wind up the second support film c8 of the membrane electrode strip b5, so that when the third composite mechanism 7 and the fourth composite mechanism 9 respectively composite the second gasket strip and the second adhesive film strip to the second side e2 of the membrane electrode strip b5, the second gasket strip and the second adhesive film strip can adhere to the second frame d4 of the membrane electrode unit of the membrane electrode strip b5.

[0039] Specifically, in this embodiment, the first adhesive film feed mechanism 4 conveys a first adhesive film strip including a third backing film c13 and a plurality of first adhesive film portions d8 stacked on one side of the third backing film c13, the plurality of first adhesive film portions d8 being spaced apart along the length direction of the first adhesive film strip. The second adhesive film feed mechanism 8 conveys a second adhesive film strip including a fourth backing film c17 and a plurality of second adhesive film portions d11 stacked on one side of the fourth backing film c17, the plurality of second adhesive film portions d11 being spaced apart along the length direction of the second adhesive film strip.

[0040] The packaging equipment also includes a third winding mechanism a3, which is arranged downstream of the fourth composite mechanism 9 and upstream of the first die-cutting mechanism 91. This third winding mechanism a3 is used to wind up the third support film c13 of the first adhesive film strip composited with the membrane electrode strip b5, allowing the first die-cutting mechanism 91 to cut the membrane electrode strip b5 while avoiding cutting the third support film c13. It is understood that the first die-cutting mechanism 91 cuts the membrane electrode strip b5 into membrane electrode sheets containing individual membrane electrode units, without die-cutting the fourth support film c17, ensuring that the die-cut membrane electrode sheets are carried on the fourth support film c17 and continue to be conveyed downstream along with the fourth support film c17.

[0041] In a specific embodiment, the packaging device further 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 support film c17 of the second adhesive tape passing through, so that the film electrode sheet is separated from the fourth support film c17.

[0042] Furthermore, the packaging equipment also includes a conveying mechanism 92, which is arranged downstream of the first die-cutting mechanism 91. This conveying mechanism 92 receives the membrane electrode sheet separated from the fourth base film c17 and conveys the membrane electrode sheet downstream. Optionally, the conveying mechanism 92 can be a vacuum belt conveyor, which can adsorb and fix the membrane electrode sheet and convey it downstream. Simultaneously, the fourth winding mechanism a4 winds up the fourth base film c17, causing the membrane electrode sheet to gradually separate from the fourth base film c17.

[0043] Please see Figure 1 and Figure 2 In the embodiments of this 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 a first initial gasket strip c11 to the first composite mechanism 3. The first initial gasket strip c11 unwinds and outputs by the first gasket unwinding assembly 21 includes a first release film and a plurality of first gaskets d7 disposed on one side of the first release film, the plurality of first gaskets d7 being spaced apart along the length direction of the first release film. The first release film winding assembly 23 is used to wind the first release film of the first initial gasket strip c11 on the upstream side of the first composite mechanism 3, so that the first gaskets d7 of the first initial gasket strip c11 enter the first composite mechanism 3 after separating from the first release film, thereby causing the first composite mechanism 3 to press the first gaskets d7 onto the first frame d1 of the membrane electrode unit of the membrane electrode strip b5.

[0044] Furthermore, the first gasket feeding mechanism 2 also includes a fifth roller assembly 24 and a first waste edge winding assembly 22. The fifth roller assembly 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 roller assembly 24, such that after the first initial gasket strip c11 unwound from the first gasket unwinding assembly 21 passes through the fifth roller assembly 24, the waste edge of the first initial gasket strip c11 is wound up by the first waste edge winding assembly 22, so that the waste edge of the first initial gasket strip c11 entering the first composite mechanism 3 has been removed, avoiding the waste edge from affecting the adhesion between the first gasket d7 and the first frame d1 of the membrane electrode unit.

[0045] Please see Figure 1 and Figure 3In the embodiments of this application, the first film feeding mechanism 4 includes a third backing film unwinding assembly 41, a first die-cutting assembly 42, a first mask winding assembly 43, a first composite assembly 44, and a first film unwinding assembly 45. The third backing film unwinding assembly 41 is used to unwind and output a third backing film c13 to the first die-cutting assembly 42. A first mask is stacked on one side of the third backing film c13. The first die-cutting assembly 42 is used to die-cut the first mask on the third backing film c13 (the first mask is die-cut to form a first mask portion d6 and waste material), that is, the first die-cutting assembly 42 only die-cuts the first mask and does not die-cut the third backing 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 material 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 backing film c13. The first composite assembly 44 is arranged downstream of the first die-cutting assembly 42 and upstream of the second composite mechanism 5. The first film unwinding assembly 45 is used to unwind and output the first initial film strip c14 to the first composite assembly 44, such that both the first initial film strip c14 and the die-cut third support film c13 are conveyed to the first composite assembly 44, and the first initial film strip c14 is located on the side of the third support film c13 with the first mask portion d6 as it passes through the first composite assembly 44. The first composite assembly 44 is used to press the passing first initial film strip c14 onto the side of the third support film c13 with the first mask portion d6.

[0046] Furthermore, the first film feeding mechanism 4 also includes a second die-cutting assembly 46, a first roller assembly 47, a first row of waste tape unwinding assembly 48, and a first row of waste tape winding assembly 49. The second die-cutting assembly 46 is arranged downstream of the first composite assembly 44, such that the first initial film strip c14, after being laminated with the third backing film c13, enters the second die-cutting assembly 46. The second die-cutting assembly 46 is used to die-cut the passing first initial film strip c14, such that the first initial film strip c14 is die-cut into a first film d8 and waste material. The first roller assembly 47 is arranged downstream of the second die-cutting assembly 46 and upstream of the second composite 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 roller assembly 47, so that the third backing film c13, the first initial adhesive film material c14 and the first row of waste tape c15 are all conveyed to the first roller assembly 47, and the first row of waste tape c15 is located on the side of the third backing film c13 that is attached to the first initial adhesive film material c14, thereby allowing the first row of waste tape c15 to adhere to the waste material formed after the first initial adhesive film material c14 is die-cut. The first row of waste tape winding assembly 49 is arranged downstream of the first roller assembly 47 and is used to wind up the first row of waste tape c15, so that the waste portion of the first initial adhesive film material tape c14 is wound up together with the first row of waste tape c15, while the first adhesive film d8 formed by die-cutting the first initial adhesive film material tape c14 continues to be adhered to the third backing film c13. That is, the first adhesive film material tape provided to the second composite mechanism 5 includes the third backing film c13 and the first mask portion d6 and the first adhesive film d8 adhered to the same side of the third backing film c13. The second composite mechanism 5 is used to press the first adhesive film d8 of the first adhesive film material tape to the first frame d1 of the membrane electrode unit of the membrane electrode material tape b5.

The second release film winding assembly 63 is used to wind the second release film of the second initial gasket strip c16 on the upstream side of the second composite mechanism 5, so that the second gaskets d10 of the second initial gasket strip c16 enter the third composite mechanism 7 after separating from the second release film, thereby causing the third composite mechanism 7 to press the second gaskets d10 onto the second frame d4 of the membrane electrode unit of the membrane electrode strip b5.

A second mask is disposed on one side of the fourth base film c17. The ninth die-cutting assembly 82 is used to die-cut the second mask on the fourth base film c17; that is, the ninth die-cutting assembly 82 only die-cuts the second mask and does not die-cut the fourth base film c17. The second mask winding assembly 83 is arranged downstream of the ninth die-cutting assembly 82 and is used to wind up the second mask on the fourth base film c17, such that the second mask portion d9 formed by the die-cutting of the second mask by the ninth die-cutting assembly 82 remains on the fourth base film c17, while the other portions of the second mask are wound up by the second mask winding assembly 83. The second composite assembly 84 is arranged downstream of the ninth die-cutting assembly 82 and upstream of the fourth composite mechanism 9. The second film unwinding assembly 85 unwinds and outputs the second initial film strip c18 to the second composite assembly 84, such that both the second initial film strip c18 and the die-cut fourth support film c17 are conveyed to the second composite assembly 84, and the second initial film strip c18 is located on the side of the fourth support film c17 with the second mask portion d9 as it passes through the second composite assembly 84.

The third die-cutting assembly 86 is arranged downstream of the second composite assembly 84, such that the second initial film strip c18, after being laminated with the fourth backing film c17, enters the third die-cutting assembly 86. The third die-cutting assembly 86 is used to die-cut the passing second initial film strip c18. The second roller assembly 87 is arranged between the downstream of the third die-cutting assembly 86 and the upstream of the fourth composite mechanism 9.

The second row of waste tape winding assembly 89 is arranged downstream of the second roller assembly 87 and is used to wind up the second row of waste tape c19, so that the waste portion of the second initial adhesive film material tape c18 is wound up together with the second row of waste tape c19, while the second adhesive film d11 formed by die-cutting the second initial adhesive film material tape c18 continues to be adhered to the third backing film c13. That is, the second adhesive film material tape provided to the fourth laminating mechanism 9 includes the fourth backing film c17 and the second mask portion d9 and the second adhesive film d11 adhered to the same side of the fourth backing film c17. The fourth laminating mechanism 9 is used to press the second adhesive film d11 of the second adhesive film material tape to the second frame d4 of the membrane electrode unit of the membrane electrode material tape b5.

[0051] Please see Figure 1 and Figure 6 In the embodiments of this 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 CCM strips, first frame strips, and second frame strips to the fifth composite mechanism 14. The fifth composite mechanism 14 is used to press the first frame strip and the second frame strip onto both sides of the CCM strip, so that the first frame strip, CCM strip, and second frame strip are sequentially stacked to form the membrane electrode strip b5. This achieves the production of the membrane electrode strip b5 using a roll-to-roll continuous composite method, greatly improving production efficiency and better meeting capacity requirements.

[0052] Specifically, in this embodiment, the fifth composite mechanism 14 includes a primary composite component 141 and a secondary composite component 143. The primary composite component 141 is positioned downstream of the CCM feeding component 11 and the first border feeding component 12, such that the CCM feeding component 11 and the first border feeding component 12 respectively feed the CCM strip and the first border strip to the primary composite component 141. The primary composite component 141 is used to press the passing CCM strip and the first border strip together. The secondary composite component 143 is positioned downstream of the primary composite component 141 and the second border feeding component 143, such that the composite strip formed by pressing the CCM strip and the first border strip together is fed from the primary composite component 141 to the secondary composite component 143, and the second border feeding component 13 feeds the second border strip to the secondary composite component 143. The secondary composite component 143 is used to press the composite strip (i.e., the CCM strip and the first frame strip) and the second frame strip together to form a membrane electrode strip b5 consisting of the first frame strip, the CCM strip and the second frame strip stacked in sequence.

[0053] Specifically, in this embodiment, the CCM feeding assembly 11 includes a CCM unwinding assembly 111, a fourth die-cutting assembly 114, and a CCM waste edge winding assembly 115. The CCM unwinding assembly 111 is used to unwind and output an initial CCM strip c1 to the fourth die-cutting assembly 114. The initial CCM strip c1 unwinded by the CCM unwinding assembly 111 includes a fifth backing film and a CCM layer laminated 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 strip c1, so that the CCM layer is die-cut into a plurality of CCM d3 arranged along the length direction of the fifth backing film. The CCM waste edge winding assembly 115 is arranged downstream of the fourth die-cutting assembly 114 and is used to wind up the waste edges formed by the die-cutting of the CCM layer of the initial CCM strip c1.

[0054] Furthermore, the CCM feeding assembly 11 also includes a third composite assembly 113, a cut film unwinding assembly 112, and a cut film rewinding assembly 116. The third composite assembly 113 is arranged downstream of the CCM unwinding assembly 111 and upstream of the fourth die-cutting assembly 114, such that the initial CCM tape c1 unwound from the CCM unwinding assembly 111 sequentially passes 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 cut film unwinding assembly 112 is arranged upstream of the third composite assembly 113 and is used to unwind and output the cut film c2 to the third composite assembly 113, so that the third composite assembly 113 composites the cut film c2 with the initial CCM tape c1 (the cut film c2 is stacked on the side of the fifth backing film facing away from the CCM layer), thereby increasing the rigidity of the composite tape and improving the cutting quality of the initial CCM tape being die-cut by the fourth die-cutting assembly 114. The cut film winding assembly 116 is arranged downstream of the fourth die-cutting assembly 114 to wind up the cut film c2, thereby preventing the cut film c2 from continuing to be conveyed downstream along with the initial CCM tape c1.

[0055] Furthermore, the CCM feeding assembly 11 also includes a first guide roller, a first transfer film unwinding assembly 117, and a first transfer film rewinding assembly 118. The first guide roller is arranged between the downstream of the fourth die-cutting assembly 114 and the upstream of the primary laminating assembly 141. The first transfer film unwinding assembly 117 is used to unwind and output the first transfer film c4 to the first guide roller, so that the initial CCM tape c1 and the first transfer film c4 are wound together around the first guide roller, so that the initial CCM tape c1 and the first transfer film c4 are adhered to each other (the first transfer film c4 is stacked on the side of the fifth backing film opposite to the CCM layer), thereby using the first transfer film c4 to adjust the unwinding speed of the initial CCM tape c1. The first transfer film winding assembly 118 is arranged downstream of the primary composite 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 tape c1 is separated from the first transfer film c4 and the fifth backing film, and the CCM layer of the initial CCM tape c1 is pressed together with the first edge tape by the primary composite assembly 141.

The first backing film unwinding assembly 121 and the first frame unwinding assembly 125 are respectively used to unwind and output the first backing film c5 and the first initial frame material c6 to the fifth die-cutting assembly 126. The fifth die-cutting assembly 126 is used to die-cut the passing first initial frame material c6, so that the first initial frame material c6 is film-cut to form a plurality of first frames d1 arranged along the length direction of the first backing film c5. The third roller assembly 127 is arranged downstream of the fifth die-cutting assembly 126 and upstream of the primary composite assembly 141. The third row of waste tape unwinding assembly 128 is arranged upstream of the third roller assembly 127 and is used to unwind and output the third row of waste tape c7 to the third roller assembly 127. This allows the first initial frame material tape c6, the first backing film c5, and the third row of waste tape c7 to pass through the third roller assembly 127 together. The third row of waste tape c7 is stacked on the side of the first initial frame material tape c6 away from the first backing film c5. This allows the third roller assembly 127 to press the third row of waste tape c7 onto the first initial frame material tape c6, ensuring that the third row of waste tape c7 adheres to the waste material formed by the 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 material formed by the die-cutting of the first initial border material tape c6 is wound together with the third row of waste tape c7, and the first border d1 formed by the die-cutting of the first initial border material tape c6 is attached to the first backing film c5 and enters the primary composite assembly 141 along with the first backing film c5.

[0057] Furthermore, a third release film is also stacked on one side of the first initial frame strip c6 unwound by the first frame unwinding assembly 125. This third release film is located on the side of the first initial frame strip c6 opposite to the first support film c5. The third row waste tape winding assembly 129 is used to wind up the third row waste tape c7 and the third release film, thereby avoiding any adverse effects of the third release film on subsequent strip lamination.

[0058] Furthermore, the first frame feeding assembly 12 also includes a seventh pair of rollers assembly. This seventh pair of rollers assembly is located downstream of the first backing film unwinding assembly 121 and the first frame unwinding assembly 125, and upstream of the fifth die-cutting assembly 126, such that the first backing film c5 and the first initial frame strip c6, respectively unwound by the first backing film unwinding assembly 121 and the first frame unwinding assembly 125, are together conveyed to the seventh pair of rollers assembly. This seventh pair of rollers assembly is used to press the passing first backing film c5 and the first initial frame strip c6 together.

[0059] Specifically, in this 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 this third mask is located on the side of the first support film c5 that is in contact with the first initial frame strip c6. The first frame feeding assembly 12 further 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 passing first support film c5, so that the third mask is cut into 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 material formed by the die-cutting of the third mask, so that the die-cut third mask portions d2 continue to adhere to the first support film c5. Thus, when the composite component 141 presses the passing CCM strip with the first frame strip, the CCMd3 on the CCM strip is pressed onto the first frame d2 on the first frame strip.

[0060] In embodiments of this application, the second frame feeding assembly 13 includes a second backing film unwinding assembly 131, a second frame unwinding assembly 135, a seventh die-cutting assembly 136, a fourth roller assembly, a fourth row of waste tape unwinding assembly 137, and a fourth row of waste tape winding assembly 138. The second backing film unwinding assembly 131 and the second frame unwinding assembly 135 are respectively used to unwind and output the second backing 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 passing second initial frame material strip c9, so that the second initial frame material strip c9 is film-cut to form a plurality of second frames d4 arranged along the length direction of the second backing film c8. The fourth pair of rollers assembly is arranged between the downstream of the seventh die-cutting assembly 136 and the upstream of the secondary composite assembly 143. The fourth row of waste tape unwinding assembly 137 is arranged upstream of the fourth pair of rollers assembly and is used to unwind and output the fourth row of waste tape c10 to the fourth pair of rollers assembly. This allows the second initial border material tape c9, the second backing film c8, and the fourth row of waste tape c10 to pass through the fourth pair of rollers assembly together. The fourth row of waste tape c10 is stacked on the side of the second initial border material tape c9 away from the second backing film c8. This allows the fourth pair of rollers assembly to press the fourth row of waste tape c10 onto the second initial border material tape c9, ensuring that the fourth row of waste tape c10 adheres to the waste material formed by the die-cutting of the second initial border 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 the die-cutting of the second initial border material c9 is wound up together with the fourth row of waste tape c10, and the second border d4 formed by the die-cutting of the second initial border material c9 is attached to the second backing film c8 and enters the secondary composite assembly 143 along with the second backing film c8.

[0061] Furthermore, a fourth release film is also stacked on one side of the second initial border strip c9 unwound by the second border unwinding assembly 135. This fourth release film is located on the side of the second initial border strip c9 opposite to the second support film c8. The fourth row waste tape winding assembly 138 is used to wind up the fourth row waste tape c10 and the fourth release film, thereby avoiding any adverse effects of the fourth release film on subsequent strip lamination.

[0062] Furthermore, the second frame feeding assembly 13 also includes an eighth pair of rollers assembly 134. This eighth pair of rollers assembly 134 is located downstream of the second backing film unwinding assembly 131 and the second frame unwinding assembly 135, and upstream of the seventh die-cutting assembly 136, such that the second backing film c8 and the second initial frame strip c9, respectively unwound by the second backing film unwinding assembly 131 and the second frame unwinding assembly 135, are together conveyed to the eighth pair of rollers assembly 134. This eighth pair of rollers assembly 134 is used to press the passing second backing film c8 and the second initial frame strip c9 together.

[0063] Specifically, in this embodiment, a fourth mask is stacked on one side of the second support film c8 unwound from the second support film unwinding assembly 131, and this fourth mask is located on the side of the second support film c8 that is in contact with the second initial frame strip c9. The second frame feeding assembly 13 further 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 passing second support film c8, so that the fourth mask is cut into 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 for the fourth mask portions d5), so that the die-cut fourth mask portions d5 continue to be attached to the second support film c8.

[0064] Thus, when the secondary composite assembly 143 presses the passing CCM strip with the second frame strip, the CCM d3 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 sequentially. The membrane electrode strip b5 includes a plurality of membrane electrodes d12 arranged along its own length direction. Each membrane electrode d12 includes a CCM d3 and a first frame d1 and a second frame d4 respectively stacked on both sides of the CCM d3. The first mask portion d2 is used to protect the area of ​​the CCM d3 not covered by the first frame d1, and the second mask portion d5 is used to protect the area of ​​the CCM d3 not covered by the second frame d4.

[0065] Based on the above-described packaging equipment, this application also provides a packaging method. Please refer to [link to relevant documentation]. Figure 1 and Figure 7 The encapsulation method includes the following steps: S10. Prepare membrane electrode material strip b5 using membrane electrode feeding mechanism 1; S20. The membrane electrode material strip b5 is output using the membrane electrode feeding mechanism 1, the first gasket material strip is output using the first gasket feeding mechanism 2, and the first composite mechanism 3 is used to press the first gasket material strip onto the first side e1 of the membrane electrode material strip b5.

Figure 22 ).

[0066] In this way, continuous roll-to-roll lamination of the membrane electrode material strip b5, the first gasket material strip, the first adhesive film material strip, the second gasket material strip, and the second adhesive film material strip is achieved. The membrane electrode material strip b5, after lamination 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 die-cut to obtain the membrane electrode sheet. Compared with the sheet lamination method in the prior art, the roll-to-roll continuous lamination method in this application greatly improves production efficiency and can better meet capacity requirements.
