[0002] As a power generation device that directly and efficiently converts the chemical energy in fuel and oxidant into electrical energy, hydrogen fuel cells have significant advantages such as high power conversion efficiency (theoretical power generation efficiency can reach 85% - 90%) and environmental protection. They have been widely used in many fields such as national defense, transportation, and industry. Since the voltage of a single fuel cell is low, polymer films play a key role in improving the performance of hydrogen fuel cells.

[0003] The existing patent (Announcement No.: CN115122427A) discloses a hydrogen energy fuel cell PEN film punching method and equipment, including the following specific steps: placing the placement component on the leftmost side of the forward component, and making the suction cup on the right side of the processing table directly below the positioning component. At this time, one end of the PEN film is attached to the suction cup on the right side of the processing table to achieve adsorption and fixation of one end of the PEN film on the right side of the processing table by the adsorption component. The above-mentioned hydrogen energy fuel cell PEN film punching method and equipment moves the placement component through the forward component, flattens the PEN film laid on the placement component through the leveling component, and punches the PEN film laid on the placement component through the punching component.

[0011] A punching method for a hydrogen energy fuel cell PEN film punching device comprises the following steps: S1. First, the PEN film is placed on the surface of the punching table through mechanical transportation. When the driving motor is started, it drives the half-toothed disc to rotate. When the half-toothed disc rotates, it drives the half-gear to rotate. When the half-toothed disc rotates, it meshes with the gear, which drives the gear to rotate forward. When the half-toothed disc is separated from the gear, the half-gear will mesh with the gear and drive the gear to reverse. This reciprocating process will form a forward and reverse reciprocating rotation of the gear. When the gear rotates, the swing rod is driven to rotate back and forth through the rotating rod. The swing rod swings to the left and slides along the track of the U-shaped groove through the sliding rod inside the U-shaped groove. When the swing rod swings to the left, it drives the guide rod to slide to the left inside the support block. At the same time, the guide rod passes through the track of the U-shaped groove and presses the support block to slide downward on the surface of the slide rail. When the guide rod slides, the distance between the support block and the fixed block is shortened, and the second connecting rod is squeezed by the first connecting rod, and the second connecting rod rotates through the spline rod; S2. When the spline rod rotates, it drives the toothed disc to rotate. When the toothed disc rotates, it drives the meshing gear to rotate. When the gear rotates, it drives the pawl to rotate. At this time, the pawl will not be blocked by the ratchet and will not drive the card tooth to rotate. However, when the gear rotates, it will drive the connecting rod to rotate. When the connecting rod rotates, it will drive the spring in the card tooth to contract. At this time, the card tooth is stuck by the card block and cannot rotate. After the guide rod drives the air cavity at the lower end of the fixed block and the punching disk to descend to the surface of the punching table, the PEN film is punched. At this time, the guide slide rod and the ring will enter the double-layer annular bevel groove and the annular bevel groove respectively, and the guide slide rod will pass through the L-shaped telescopic rod When the guide slide rod rises, it will pull the toothed disc upward on the surface of the spline rod through the annular groove and separate from the gear. At the same time, the ring will slide upward inside the limit groove through the annular groove. The ring drives the block to slide upward and separate from the clamping teeth. At this time, the clamping teeth lose resistance and the clamping teeth are rotated by the spring. When the clamping teeth rotate, the hollow rod is driven to rotate. When the hollow rod rotates, the piston rod is driven to slide upward inside the hollow rod along the circulating inclined groove, while the piston rod cannot rotate in the air cavity. When the piston rod rises, air is sucked into the air cavity through the air pipe, and the PEN film is adsorbed on the lower surface of the punching disc at the same time. S3. After the punching is completed, the swing rod will swing to the right, and the sliding rod will slide along the track of the U-shaped groove inside the U-shaped groove. When the swing rod swings to the right, it will drive the guide rod to slide to the right inside the support block, and at the same time drive the fixed block with the adsorbed PEN film to enter the next area. At this time, the gear plate will rotate in the opposite direction through the spline rod, and at the same time drive the arc rack to rotate. The arc rack will rotate from the lower end of the gear when the gear plate rotates forward, and when the gear plate rises, the arc rack will be on the same horizontal line with gear one, and It meshes with the gear and drives the gear to rotate. When the gear rotates, the ratchet is clamped by the pawl, and the ratchet drives the clamping teeth to rotate. At this time, the clamping teeth have not been clamped by the block. When the clamping teeth rotate, they drive the hollow rod to rotate. When the hollow rod rotates, it drives the piston rod along the circulating inclined groove and slides downward inside the hollow rod. When the piston rod descends, the air pipe blows air through the air cavity to blow the PEN film to the next area to prevent the PEN film from sticking to the surface of the punching disk. Finally, the ring and the guide slide rod will be reset through the double-layer annular inclined groove and the annular inclined groove.

[0012] In the present invention, the hollow rod is driven to rotate by the rotation of the latch teeth, and the rotation of the hollow rod drives the piston rod along the circulating inclined groove and slides upward inside the hollow rod, while the piston rod cannot rotate in the air cavity. When the piston rod rises, air is sucked into the air cavity through the air pipe, and the PEN film is adsorbed on the lower surface of the punching disk at the same time, so that the PEN film can be kept in good condition and can be prevented from falling.

[0013] In the present invention, the hollow rod is driven to rotate by the rotation of the latch teeth, and the rotation of the hollow rod drives the piston rod along the circulating inclined groove and slides downward inside the hollow rod. When the piston rod descends, the air pipe blows air through the air cavity to blow the PEN film to the next area, thereby preventing the PEN film from sticking to the surface of the punching disc and achieving rapid demolding.

[0023] The use method and advantages of the present invention: The hydrogen energy fuel cell PEN film punching device and punching method, when in use, the working process is as follows: like Figures 1 to 15 As shown; A punching method for a hydrogen energy fuel cell PEN film punching device comprises the following steps: S1. First, the PEN film is placed on the surface of the punching table 3 by mechanical transportation. When the driving motor 41 is started, the semi-toothed disc 42 is driven to rotate. When the semi-toothed disc 42 rotates, the semi-gear 43 is driven to rotate. When the semi-toothed disc 42 rotates, it meshes with the gear 44, which drives the gear 44 to rotate forward. When the semi-toothed disc 42 is separated from the gear 44, the semi-gear 43 meshes with the gear 44, driving the gear 44 to rotate reversely. This reciprocating process will form a reciprocating rotation of the gear 44 in the forward and reverse directions. When the gear 44 rotates, it drives the swing rod 51 through the rotating rod 45. The swing rod 51 swings to the left and slides along the track of the U-shaped groove 52 through the sliding rod 53 inside the U-shaped groove 52. When the swing rod 51 swings to the left, it drives the guide rod 56 to slide to the left inside the support block 55. At the same time, the guide rod 56 passes through the track of the U-shaped groove 52 and presses the support block 55 to slide downward on the surface of the slide rail 54. When the guide rod 56 slides, the distance between the support block 55 and the fixed block 61 is shortened, and the connecting rod 58 is squeezed by the connecting rod 1 57, and the connecting rod 58 is rotated through the spline rod 62. S2, when the spline rod 62 rotates, it drives the toothed disc 63 to rotate, and when the toothed disc 63 rotates, it drives the meshing gear 1 92 to rotate, and when the gear 1 92 rotates, it drives the pawl 96 to rotate. At this time, the pawl 96 will not be blocked by the ratchet 95 and will not drive the card tooth 91 to rotate, but when the gear 1 92 rotates, it will drive the connecting rod 97 to rotate, and when the connecting rod 97 rotates, it will drive the spring spring 98 in the card tooth 91 to contract. At this time, the card tooth 91 is stuck by the block 84 and cannot rotate. After the guide rod 56 drives the air cavity 71 at the lower end of the fixed block 61 and the punching disk 72 to descend to the surface of the punching table 3, after the PEN film is punched, the guide slide bar 68 and the ring 82 will enter the double-layer annular bevel groove 66 and the annular bevel groove 81 respectively, and the guide slide bar 68 will be lifted by the L-shaped telescopic rod 67. The toothed disc 63 is pulled upward on the surface of the spline rod 62 through the annular groove 65 and separated from the gear 1 92. At the same time, the ring 82 also slides upward inside the limiting groove 83 through the annular groove 81. The ring 82 drives the block 84 to slide upward and separate from the latch 91. At this time, the latch 91 loses resistance and the latch 91 is rotated by the spring spring 98. When the latch 91 rotates, the hollow rod 93 is driven to rotate. When the hollow rod 93 rotates, the piston rod 74 is driven to slide upward inside the hollow rod 93 along the circulating groove 94, while the piston rod 74 cannot rotate in the air cavity 71. When the piston rod 74 rises, air is sucked into the air cavity 71 through the air pipe 73, and the PEN film is adsorbed on the lower surface of the punching disc 72. This can ensure the intact state of the PEN film and prevent the PEN film from falling off. S3. After the punching is completed, the swing rod 51 will swing to the right, and the sliding rod 53 will slide along the track of the U-shaped groove 52 inside the U-shaped groove 52. When the swing rod 51 swings to the right, it drives the guide rod 56 to slide to the right inside the support block 55, and at the same time drives the fixed block 61 with the adsorbed PEN film to enter the next area. At this time, the toothed disc 63 will rotate in the opposite direction through the spline rod 62, and at the same time drive the arc-shaped rack 64 to rotate. The arc-shaped rack 64 rotates from the lower end of the gear 1 92 when the toothed disc 63 rotates forward, and when the toothed disc 63 rises, the arc-shaped rack 64 will be on the same horizontal line as the gear 1 92 and mesh with the gear 1 92, bringing The movable gear 92 rotates, and when the gear 92 rotates, the ratchet 95 is clamped by the pawl 96, and the latch tooth 91 is driven to rotate by the ratchet 95. At this time, the latch tooth 91 has not been clamped by the clamping block 84. When the latch tooth 91 rotates, it drives the hollow rod 93 to rotate. When the hollow rod 93 rotates, it drives the piston rod 74 along the circulating inclined groove 94 and slides downward inside the hollow rod 93. When the piston rod 74 descends, the air pipe 73 blows air through the air cavity 71 to blow the PEN film to the next area to prevent the PEN film from sticking to the surface of the punching disk 72, thereby achieving rapid demolding. Finally, the ring 82 and the guide slide bar 68 will be reset through the double-layer annular inclined groove 66 and the annular inclined groove 81.

8. A punching method for a hydrogen energy fuel cell PEN film punching device, using a hydrogen energy fuel cell PEN film punching device as claimed in any one of claims 1 to 7, characterized in that: The steps include: S1. First, the PEN film is placed on the surface of the punching table (3) through mechanical transportation. When the driving motor (41) is started, the semi-toothed disc (42) is driven to rotate. When the semi-toothed disc (42) rotates, the semi-gear (43) is driven to rotate. When the semi-toothed disc (42) rotates, it meshes with the gear (44), which drives the gear (44) to rotate forward. When the semi-toothed disc (42) and the gear (44) are separated, the semi-gear (43) meshes with the gear (44), which drives the gear (44) to rotate reversely. This reciprocating process will form a reciprocating rotation of the gear (44) in the forward and reverse directions. When the gear (44) rotates, it drives the swing rod (51) forward through the rotating rod (45). The swing rod (51) swings leftward and slides along the track of the U-shaped groove (52) through the sliding rod (53). When the swing rod (51) swings leftward, it drives the guide rod (56) to slide leftward inside the support block (55). At the same time, the guide rod (56) passes through the track of the U-shaped groove (52) and presses the support block (55) to slide downward on the surface of the slide rail (54). When the guide rod (56) slides, the distance between the support block (55) and the fixed block (61) is shortened, and the second connecting rod (58) is squeezed by the first connecting rod (57). The second connecting rod (58) rotates through the spline rod (62); S2. When the spline rod (62) rotates, it drives the toothed disc (63) to rotate. When the toothed disc (63) rotates, it drives the meshing gear 1 (92) to rotate. When the gear 1 (92) rotates, it drives the pawl (96) to rotate. At this time, the pawl (96) will not be blocked by the ratchet wheel (95) and will not drive the latching tooth (91) to rotate. However, when the gear 1 (92) rotates, it drives the connecting rod (97) to rotate. When the connecting rod (97) rotates, it drives the spring in the latching tooth (91) to rotate. The spring (98) is contracted, and the latching tooth (91) is stuck by the latching block (84) and cannot rotate. After the guide rod (56) drives the air cavity (71) and the punching disc (72) at the lower end of the fixed block (61) to descend to the surface of the punching table (3), the PEN film is punched. At this time, the guide slide bar (68) and the ring (82) will enter the double-layer annular bevel groove (66) and the annular bevel groove (81) respectively, and the guide slide bar (68) will pass through the L-shaped telescopic rod (6 7) rises, and when the guide slide bar (68) moves upward, it will pull the toothed disc (63) upward on the surface of the spline rod (62) through the annular groove (65) and separate from the gear one (92). At the same time, the ring (82) will slide upward inside the limit groove (83) through the annular groove (81), and the ring (82) will drive the block (84) to slide upward and separate from the clamping tooth (91). At this time, the clamping tooth (91) loses its resistance and is released through the spring spring (9 8) rotating the latching teeth (91), and when the latching teeth (91) rotate, the hollow rod (93) is driven to rotate. When the hollow rod (93) rotates, the piston rod (74) is driven to slide upward along the circulation chute (94) inside the hollow rod (93), while the piston rod (74) cannot rotate in the air cavity (71). When the piston rod (74) rises, air is sucked into the air cavity (71) through the air pipe (73), and the PEN film is adsorbed on the lower surface of the punching disc (72); S3. After the punching is completed, the swing rod (51) will swing to the right, and the sliding rod (53) will slide along the track of the U-shaped groove (52) inside the U-shaped groove (52). When the swing rod (51) swings to the right, it drives the guide rod (56) to slide to the right inside the support block (55), and at the same time drives the fixed block (61) to enter the next area with the adsorbed PEN film. At this time, the toothed disc (63) will rotate in the opposite direction through the spline rod (62), and at the same time drive the arc-shaped rack (64) to rotate. When the toothed disc (63) rotates forward, the arc-shaped rack (64) rotates from the lower end of the gear 1 (92). When the toothed disc (63) rises, the arc-shaped rack (64) will be on the same horizontal line as the gear 1 (92) and mesh with the gear 1 (92), bringing The movable gear 1 (92) rotates. When the gear 1 (92) rotates, the ratchet wheel (95) is clamped by the pawl (96). The ratchet wheel (95) drives the latching tooth (91) to rotate. At this time, the latching tooth (91) has not been clamped by the clamping block (84). When the latching tooth (91) rotates, it drives the hollow rod (93) to rotate. When the hollow rod (93) rotates, it drives the piston rod (74) along the circulation inclined groove (94) and slides downward inside the hollow rod (93). When the piston rod (74) descends, the air pipe (73) blows air through the air cavity (71) to blow the PEN film to the next area to prevent the PEN film from sticking to the surface of the punching disc (72). Finally, the ring (82) and the guide slide rod (68) are reset through the double-layer annular inclined groove (66) and the annular inclined groove (81).
