[0002] Type IV hydrogen storage cylinders, as a high-pressure lightweight hydrogen storage solution, provide higher hydrogen storage density and lower weight than traditional metal cylinders, helping to improve energy efficiency and reduce carbon emissions, and are of great significance to the development of hydrogen energy industry.

[0042] The technical solutions of the present application will be described below in conjunction with the drawings. Obviously, the following described embodiments are part of the embodiments of the present application, not all embodiments.

[0043] The IV type hydrogen storage cylinder, as a high-pressure lightweight hydrogen storage scheme, provides higher hydrogen storage density and lower weight than traditional metal cylinders, which helps to improve energy efficiency and reduce carbon emissions, and has important significance for the development of hydrogen energy industry. Because the IV type cylinder adopts a composite structure of plastic liner, metal boss end and carbon fiber winding layer, the interface problem between the metal boss and the high polymer material exists in the end part, which is easy to become a potential weak point when bearing high pressure and cyclic load. Therefore, the research and application of end reinforcement technology are crucial to ensure the safety of the IV type hydrogen storage cylinder.

[0044] End cap reinforcement technology aims to improve the strength and durability of the end cap area by enhancing materials and structural design, thereby reducing the risk of leakage and rupture. Current techniques involve manually laying prepreg sheets or spirally or circularly winding carbon fiber composite materials at the end cap. Manual laying methods suffer from defects such as wrinkles, poor uniformity, and inconsistent application. Achieving ideal end cap strength using spiral or circular winding requires a large amount of carbon fiber composite material. Molding methods require producing different reinforcing heads to match hydrogen storage cylinders of different shapes and sizes, incurring high production costs and time. Therefore, considering cost-effectiveness and manufacturing process feasibility, a rapid industrial method for reinforcing the end caps of Type IV hydrogen storage cylinders needs to be designed.

[0045] To address the aforementioned issues, this invention provides a hydrogen storage cylinder end cap reinforcement device and control method. This method solves the problems of poor uniformity and consistency in manual application, the need for large amounts of composite materials in spiral or ring-wound prepreg methods, and the difficulty in matching different shapes of hydrogen storage cylinders, requiring the replacement of different reinforcement heads.

[0046] refer to Figure 1 , Figure 2 and Figure 3 The present invention provides a hydrogen storage cylinder end cap reinforcement device in the following embodiments:

[0047] Reference Figure 3 As shown, the hydrogen storage cylinder head reinforcement device in this embodiment includes a clamping module 100, a laying module 200, a cutting module 300, and a transfer module 400.

[0048] The cutting module 300 is used to cut the prepreg 600 into annular reinforcing sheets 700, the transfer module 400 is used to transfer the annular reinforcing sheets 700 to the shoulder of the hydrogen storage cylinder 500 to be reinforced, the clamping module 100 is used to clamp the hydrogen storage cylinder 500, and the application module 200 is used to apply the annular reinforcing sheets 700 to the hydrogen storage cylinder 500 for reinforcement.

[0049] In this embodiment, the cutting module 300 includes a cutting mechanism 310 and a second conveying mechanism 320. The second conveying mechanism 320 is provided with a second feeding end 321, a cutting station 322, and a second discharging end 323 in sequence. The cutting mechanism 310 is located on the cutting station 322. The cutting mechanism 310 includes an annular die 311 and a cutting drive 312. The annular die 311 is located on the upper side of the cutting station 322. The cutting drive 312 is used to drive the annular die 311 to move up and down. In some other embodiments, the prepreg 600 can be cut by other means, such as ultrasonic scalpel assembly, laser cutting, die stamping, etc.

[0050] For the use mode of the cutting module 300: the prepreg 600 is arranged at the second feeding end 321 and is driven by the second conveying mechanism 320 to move to the cutting station 322. After reaching the cutting station 322, the cutting driving member 312 drives the annular cutter die 311 to move downward to cut the annular reinforcing piece 700 on the prepreg 600. The cutting driving member 312 drives the annular cutter die 311 to move upward to return to the initial position. The annular reinforcing piece 700 is driven by the second conveying mechanism 320 to move to the second discharging end 323. Meanwhile, the subsequent prepreg 600 is transported to the cutting station 322 again to perform the next cutting.

[0051] The transfer module 400 is located between the clamping module 100 and the cutting module 300. The transfer module 400 includes a grabbing mechanism 410 and a transfer driving mechanism 420. One end of the transfer driving mechanism 420 is a motion execution end, and the grabbing mechanism 410 is arranged on the motion execution end. The transfer driving mechanism 420 is used to drive the grabbing mechanism 410 to move. Specifically, in the embodiment, the transfer driving mechanism 420 is a mechanical hand structure. The mechanical hand includes multiple sections of mechanical arms connected in sequence. A steering driving structure is arranged between adjacent two sections of mechanical arms. The grabbing mechanism 410 is a suction cup which is used to adsorb and fix the annular reinforcing piece 700 through vacuum action.

[0052] In other embodiments, the transfer driving mechanism 420 can be other structures such as a truss slide rail, and the grabbing mechanism 410 can be other structures such as a clamping seat, as long as the requirements of transferring the annular reinforcing piece 700 are met.

[0053] For the use mode of the transfer module 400: the transfer driving mechanism 420 is controlled to drive the grabbing mechanism 410 to move to the second discharging end 323. The grabbing mechanism 410 is attached to the annular reinforcing piece 700 to form a seal. The grabbing mechanism 410 is controlled to be vacuumized, so that the annular reinforcing piece 700 is adsorbed on the grabbing mechanism 410. The transfer driving mechanism 420 drives the grabbing mechanism 410 to move above the hydrogen storage cylinder 500 and gradually move downward to approach the hydrogen storage cylinder 500 until the boss interface of the hydrogen storage cylinder 500 penetrates through the annular reinforcing piece 700. The grabbing mechanism 410 stops vacuumizing, and the annular reinforcing piece 700 falls on the shoulder position of the hydrogen storage cylinder 500.

[0054] The clamping module 100 includes a first conveying mechanism 120 and a clamping mechanism 110. The first conveying mechanism 120 is sequentially provided with a first feeding end 121, a clamping station 122 and a first discharging end 123. The clamping mechanism 110 is arranged at the clamping station 122. The hydrogen storage cylinder 500 is arranged at the first feeding end 121. It can be understood that the transfer module 400 is arranged between the second discharging end 323 and the first feeding end 121. After the grabbing mechanism 410 grabs the annular reinforcing piece 700, the grabbing mechanism 410 moves to the first feeding end 121 to place the annular reinforcing piece 700 on the shoulder position of the hydrogen storage cylinder 500.

[0055] Specifically, the clamping mechanism 110 includes a first clamping block 111, a second clamping block 112, and a clamping driving assembly 113. The first clamping block 111 and the second clamping block 112 are arranged opposite to each other in the transverse direction to form a clamping slot therebetween. The clamping driving assembly 113 is configured to drive the first clamping block 111 and the second clamping block 112 to move towards or away from each other, so as to clamp and fix the hydrogen storage cylinder 500 by the first clamping block 111 and the second clamping block 112.

[0056] In the top projection plane, the side of the first clamping block 111 and the second clamping block 112 close to each other is in the shape of an arc plate, so as to fit the outer periphery of the hydrogen storage cylinder 500, increase the contact area, make the force uniform, and improve the stability and safety of clamping. In the embodiment, the clamping driving assembly 113 is in the structure of a telescopic rod. The clamping driving assembly 113 is provided with two, and the two clamping driving assemblies 113 are respectively in transmission connection with the first clamping block 111 and the second clamping block 112. In other embodiments, the clamping driving assembly 113 can be in other structures, such as a slide rod, as long as it can drive the first clamping block 111 and the second clamping block 112 to clamp each other in the transverse direction.

[0057] Referring to FIG. 2, Figure 1 The paving module 200 includes a paving and shaping assembly 210 and a paving driving assembly 220. The paving and shaping assembly 210 includes a moving frame 211 and a plurality of flexible pressing strips 212. The upper ends of the plurality of flexible pressing strips 212 are connected to the moving frame 211, so that the plurality of flexible pressing strips 212 are vertically hung above the clamping slot. The paving driving assembly 220 is in transmission connection with the moving frame 211, and is configured to drive the moving frame 211 to move.

[0058] Since the shape of the flexible pressing strip 212 can change with the contacted surface and fit the contacted surface, the flexible pressing strip 212 can not only make the reinforcing sheet be paved closely, but also be suitable for surfaces of various shapes. Further, in the top projection plane, the plurality of flexible pressing strips 212 are arranged in a ring shape, so as to uniformly apply force to the ring-shaped reinforcing sheet 700.

[0059] Specifically, the flexible pressing strip 212 in the embodiment is in the structure of a chain. The flexible pressing strip 212 includes a plurality of chain links that are rotationally connected to each other. The adjacent two chain links are hingedly connected through a connecting shaft. The connecting shaft extends in the tangential direction of the circle surrounded by the plurality of flexible pressing strips 212 in the top projection plane, so that the chain link is movable in rotation in the plane perpendicular to the direction of the connecting shaft. The chain structure not only satisfies the shape change, but also has the advantages of good durability and easy replacement.

[0060] Further, the upper ends of the plurality of flexible pressing strips 212 are slidingly connected to the moving frame 211, and the plurality of flexible pressing strips 212 are slidingly adjusted along the radial direction of the circle formed by the plurality of flexible pressing strips 212 on the top projection plane, so that the size of the circle formed by the plurality of flexible pressing strips 212 on the top projection plane can be adjusted, thereby adapting to hydrogen storage cylinders 500 of different sizes.

[0061] Further, in order to make the laying position more accurate, the clamping mechanism 110 is provided with a transverse position sensor 114 connected with the laying driving assembly 220, which is used to detect the position of the first clamping block 111 and the second clamping block 112 in the transverse direction, and the signal of the transverse position sensor 114 is transmitted to the laying driving assembly 220, which drives the moving frame 211 to move along the transverse direction according to the signal, so that the circle formed by the plurality of flexible pressing strips 212 on the top projection plane is coaxial with the annular reinforcing patch 700, and the laying and shaping effect on each position of the annular reinforcing patch 700 is consistent. At the same time, the position of the plurality of flexible pressing strips 212 on the moving frame 211 is slidingly adjusted to adapt to the size of the hydrogen storage cylinder 500.

[0062] Further, the laying driving assembly 220 of the embodiment comprises a Z-axis driving structure, a Y-axis driving structure and an X-axis driving structure to realize the movement of the moving frame 211 in the vertical direction and the horizontal direction.

[0063] The laying module 200 of the embodiment further comprises a positioning mechanism 230 for positioning the clamped hydrogen storage cylinder 500, and the positioning mechanism 230 comprises a positioning rod 231 vertically connected to the bottom of the moving frame 211 and located at the center position of the plurality of flexible pressing strips 212. Specifically, the positioning rod 231 is a telescopic driving rod structure, and the lower end is provided with a sleeve 232. In actual use, the positioning rod 231 is extended so that the sleeve 232 passes through the boss joint of the hydrogen storage cylinder 500 until it contacts the first conveying mechanism 120, and the hydrogen storage cylinder 500 is positioned and fixed together with the clamping module 100.

[0064] Further, the positioning rod 231 is provided with a longitudinal sensor for detecting the telescopic length of the positioning rod 231, and the longitudinal position sensor 233 is connected with the laying driving assembly 220. The signal of the longitudinal position sensor 233 is transmitted to the laying driving assembly 220, which controls the position of the moving frame 211 in the vertical direction according to the signal. The descending position of the moving frame 211 needs to be maintained within a certain range, so that the plurality of flexible pressing strips 212 can cover the entire annular reinforcing patch 700, and at the same time, the moving frame 211 does not contact the hydrogen storage cylinder 500, so as not to cause damage to the hydrogen storage cylinder 500 or the laying and shaping assembly 210 due to mutual impact.

[0065] Specifically, due to the special structure of the sleeve 232, in the process of the moving frame 211 descending, the upper level structure of the sleeve 232 extends into the lower level structure, the longitudinal sensor detects the distance between each level structure of the sleeve 232 in the height direction, and when the height distance between each level structure of the sleeve 232 is zero, that is, the bottom ends of each level structure of the sleeve 232 coincide in height, the moving frame 211 stops moving downward.

[0066] The hydrogen storage cylinder head reinforcing equipment also comprises a frame, which is arranged at the clamping station 122 and comprises a top beam and a plurality of support columns connected vertically to the bottom of the top beam. Figure 1 As shown in the figure, the paving driving assembly 220 is connected to the top beam, and the first clamping block 111 and the second clamping block 112 are respectively connected to the bottom end of the support column through the clamping driving assembly 113.

[0067] The application further provides a control method suitable for the hydrogen storage cylinder head reinforcing equipment, which comprises the following steps:

[0068] Step S100: conveying the prepreg 600 to the cutting station 322, and cutting the prepreg 600 into annular reinforcing pieces 700 through the cutting module 300;

[0069] Step S200: transferring the annular reinforcing pieces 700 one by one to the shoulder position of the hydrogen storage cylinder 500 to be reinforced, and then conveying the hydrogen storage cylinder 500 to the clamping station 122;

[0070] Step S300: clamping and fixing the hydrogen storage cylinder 500;

[0071] Step S400: moving the plurality of flexible pressing strips 212 to contact and apply pressure to the annular reinforcing piece 700 until the annular reinforcing piece 700 is attached to the shoulder position of the hydrogen storage cylinder 500.

[0072] In step S100, the second conveying mechanism 320 is controlled to convey the prepreg 600 from the second feeding end 321 to the cutting station 322, the cutting driving part 312 controls the annular cutter die 311 to cut down to obtain the annular reinforcing piece 700, after the cutting is completed, the annular cutter die 311 moves up to the initial position, the second conveying mechanism 320 is controlled to convey the annular reinforcing piece 700 to the second discharging end 323, and at the same time, the uncut prepreg 600 is conveyed from the second feeding end 321 to the cutting station 322.

[0073] In step S200, the transfer driving mechanism 420 drives the grabbing mechanism 410 to move to the second discharge end 323, and after the grabbing mechanism 410 grabs the annular reinforcing sheet 700, the transfer driving mechanism 420 drives the grabbing mechanism 410 to move to the first feeding end 121, the first feeding end 121 is provided with the hydrogen storage cylinder 500 to be reinforced one by one, the grabbing mechanism 410 places the annular reinforcing sheet 700 on the shoulder position of the hydrogen storage cylinder 500 to be reinforced, and the second conveying mechanism 320 conveys the hydrogen storage cylinder 500 to be reinforced and the annular reinforcing sheet 700 to the clamping station 122.

[0074] In step S300, the first clamping block 111 and the second clamping block 112 are driven by the clamping driving assembly 113 to approach the hydrogen storage cylinder 500 from both sides of the hydrogen storage cylinder 500 respectively until the first clamping block 111 and the second clamping block 112 are attached to the outer periphery of the hydrogen storage cylinder 500, and the positioning rod 231 extends downward until the lower end sequentially passes through the boss interface and the hydrogen storage cylinder 500 and contacts the first conveying mechanism 120, thereby completing the clamping and fixing of the hydrogen storage cylinder.

[0075] In step S400, the laying driving assembly 220 determines the position of the hydrogen storage cylinder 500 according to the detection signal of the transverse position sensor 114, controls the displacement of the moving frame 211 in the transverse direction, controls the up and down movement position of the moving frame 211 according to the detection signal of the longitudinal position sensor 233, and drives the plurality of flexible pressing strips 212 to move downward, so that the plurality of flexible pressing strips 212 contact the annular reinforcing sheet 700 and exert pressure on the annular reinforcing sheet 700 under the action of gravity to perform laying and shaping until the annular reinforcing sheet 700 is attached to the shoulder position of the hydrogen storage cylinder 500, after the laying is completed, the laying driving assembly 220 controls the moving frame 211 to move upward, the positioning rod 231 is retracted, the first clamping block 111 and the second clamping block 112 are away from each other, and the hydrogen storage cylinder 500 is conveyed to the first discharge end 123 by the first conveying mechanism 120.
