[0023] 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, which helps to improve energy efficiency and reduce carbon emissions, and is of great significance to the development of the hydrogen energy industry. Since the Type IV cylinder adopts a composite structure of plastic liner, metal boss head and carbon fiber winding layer, there are interface problems between the metal boss and the polymer material in the head part, which can easily become a potential weak point when subjected to high pressure and cyclic loads. Therefore, the research and application of head reinforcement technology is crucial to ensure the safety of Type IV hydrogen storage cylinders.

[0024] The head reinforcement technology aims to improve the strength and durability of the head area by enhancing materials and structural design, thereby reducing the risk of leakage and rupture. The current technical means are to manually lay prepreg sheets, or to wrap carbon fiber composite materials at the head using spiral winding or hoop winding processes. Manual laying methods will have defects such as laying wrinkles, poor laying uniformity and poor consistency; if you want to get the ideal head strength at the head, you need to use a large amount of carbon fiber composite materials by spiral winding or hoop winding; laying by molding method requires the production of different reinforcement pressure heads to match hydrogen storage cylinders of different shapes and sizes, which consumes production costs and time. To this end, it is necessary to consider cost-effectiveness and the feasibility of the manufacturing process, and design a rapid industrial method for the head reinforcement technology of Type IV hydrogen storage cylinders.

[0025] In order to solve the above problems, the present invention provides a hydrogen storage cylinder head reinforcement device and control method, which solves the defects of poor paving uniformity and consistency in manual paving, and the problem that spiral winding or hoop winding prepreg methods need to consume a large amount of composite materials, and are difficult to match hydrogen storage cylinders of different shapes, and different reinforcement pressure heads need to be replaced.

[0026] refer to Figure 1 , Figure 2 and Figure 3 The present invention provides a hydrogen storage cylinder head reinforcement device with the following embodiments: Reference Figure 3As shown, the hydrogen storage cylinder head reinforcement equipment of this embodiment includes a clamping module 100, a paving module 200, a cutting module 300 and a transfer module 400.

[0027] Among them, the cutting module 300 is used to cut the prepreg 600 to obtain the annular reinforcement sheet 700, the transfer module 400 is used to transfer the annular reinforcement sheet 700 to the shoulder position of the hydrogen storage cylinder 500 to be reinforced, the clamping module 100 is used to clamp the hydrogen storage cylinder 500, and the laying module 200 is used to adhere the annular reinforcement sheet 700 to the hydrogen storage cylinder 500 for reinforcement.

[0028] In this embodiment, the cutting module 300 includes a cutting mechanism 310 and a second conveying mechanism 320, and a second feed end 321, a cutting station 322 and a second discharge end 323 are sequentially provided on the second conveying mechanism 320. The cutting mechanism 310 is arranged on the cutting station 322. The cutting mechanism 310 includes an annular cutting die 311 and a cutting drive 312. The annular cutting die 311 is located on the upper side of the cutting station 322, and the cutting drive 312 is used to drive the annular cutting die 311 to move up and down. In some other embodiments, the cutting of the prepreg 600 can be completed by other methods, such as: ultrasonic knife assembly, laser cutting, mold stamping, etc.

[0029] Regarding the usage of the cutting module 300: the prepreg 600 is arranged at the second feed end 321, and is driven by the second conveying mechanism 320 to move to the cutting station 322. After arriving at the cutting station 322, the cutting drive 312 drives the annular cutting die 311 to move downward, and cuts an annular reinforcement sheet 700 on the prepreg 600. The cutting drive 312 drives the annular cutting die 311 to move upward and return to the initial position. The annular reinforcement sheet 700 is driven by the second conveying mechanism 320 to move to the second discharge end 323. At the same time, the subsequent prepreg 600 is transported to the cutting station 322 again for the next cutting.

[0030] The transfer module 400 is located between the clamping module 100 and the cutting module 300. The transfer module 400 includes a grasping mechanism 410 and a transfer drive mechanism 420. One end of the transfer drive mechanism 420 is a motion execution end. The grasping mechanism 410 is arranged on the motion execution end. The transfer drive mechanism 420 is used to drive the grasping mechanism 410 to move. Specifically, in this embodiment, the transfer drive mechanism 420 is a robot structure. The robot includes a plurality of robot arms connected in sequence. A steering drive structure is provided between two adjacent robot arms. The grasping mechanism 410 is a suction cup, which absorbs and fixes the annular reinforcement sheet 700 through vacuum action.

[0031] In some other embodiments, the transfer drive mechanism 420 may be other structures, such as a truss slide rail, etc., and the grabbing mechanism 410 may be other structures, such as a clamp seat, etc., as long as the requirements for transferring the annular reinforcement sheet 700 are met.

[0032] Regarding the usage of the transfer module 400: control the transfer drive mechanism 420 to drive the grabbing mechanism 410 to move to the second discharge end 323, the grabbing mechanism 410 fits against the annular reinforcement sheet 700 to form a seal, control the grabbing mechanism 410 to draw a vacuum, so that the annular reinforcement sheet 700 is adsorbed on the grabbing mechanism 410, the transfer drive mechanism 420 drives the grabbing mechanism 410 to move above the hydrogen storage bottle 500, and gradually moves downward to the hydrogen storage bottle 500 until the boss interface of the hydrogen storage bottle 500 passes through the annular reinforcement sheet 700, the grabbing mechanism 410 stops drawing a vacuum, and the annular reinforcement sheet 700 falls on the shoulder position of the hydrogen storage bottle 500.

[0033] The clamping module 100 includes a first conveying mechanism 120 and a clamping mechanism 110. The first conveying mechanism 120 is provided with a first feed end 121, a clamping station 122 and a first discharge end 123 in sequence. The clamping mechanism 110 is arranged at the clamping station 122, and the hydrogen storage cylinder 500 is arranged at the first feed end 121. It can be understood that the transfer module 400 is arranged between the second discharge end 323 and the first feed end 121. After the grasping mechanism 410 grasps the annular reinforcement sheet 700, it moves to the first feed end 121 to place the annular reinforcement sheet 700 on the shoulder position of the hydrogen storage cylinder 500.

[0034] Regarding the specific structure of the clamping mechanism 110: the clamping mechanism 110 includes a first clamping block 111, a second clamping block 112 and a clamping drive assembly 113. The first clamping block 111 and the second clamping block 112 are arranged with relative spacing in the horizontal direction to form a clamping groove therebetween. The clamping drive assembly 113 is used to drive the first clamping block 111 and the second clamping block 112 to move closer to and away from each other, and the hydrogen storage cylinder 500 is fixedly clamped by the first clamping block 111 and the second clamping block 112.

[0035] Among them, on the top projection plane, the side where the first clamp 111 and the second clamp 112 are close to each other is an arc-shaped plate structure, 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 this embodiment, the clamping drive assembly 113 is a telescopic rod structure, and two clamping drive assemblies 113 are provided. The two clamping drive assemblies 113 are respectively connected to the first clamp 111 and the second clamp 112 in transmission. In some other embodiments, the clamping drive assembly 113 can be other structures, such as a sliding rod, etc., as long as it can drive the first clamp 111 and the second clamp 112 to clamp each other horizontally.

[0036] Reference Figure 1As shown, the paving module 200 includes a paving shaping component 210 and a paving driving component 220, wherein the paving shaping component 210 includes a moving frame 211 and a plurality of flexible pressure strips 212, the upper ends of the plurality of flexible pressure strips 212 are connected to the moving frame 211 so that the plurality of flexible pressure strips 212 are vertically suspended above the clamping groove; the paving driving component 220 is in transmission connection with the moving frame 211, and is used for driving the moving frame 211 to move.

[0037] Since the shape of the flexible pressure strip 212 can change with the contacted surface and fit the contacted surface, the flexible pressure strip 212 can make the reinforcement sheet tightly laid on the one hand, and can be applicable to surfaces of various shapes on the other hand. Furthermore, on the top projection surface, multiple flexible pressure strips 212 are arranged in a ring-shaped interval, so that the force can be evenly applied to the annular reinforcement sheet 700.

[0038] Specifically, the flexible pressure strip 212 of the present embodiment is a chain structure, which includes a plurality of chain links rotatably connected to each other, and two adjacent chain links are hinged by a connecting axis, and the connecting axis extends along the tangent direction of the circle enclosed by the plurality of flexible pressure strips 212 on the top projection surface, so that the chain links can rotate and move on a plane perpendicular to the direction of the connecting axis. The chain structure not only satisfies the requirement of changeable shape, but also has the advantages of good durability and easy replacement. Furthermore, the upper ends of the multiple flexible pressure strips 212 are slidably connected to the movable frame 211, and the multiple flexible pressure strips 212 are radially slidably adjusted along the circle enclosed by the multiple flexible pressure strips 212 on the top-view projection plane, so that the size of the circle enclosed by the multiple flexible pressure strips 212 on the top-view projection plane can be adjusted, thereby adapting to hydrogen storage cylinders 500 of different sizes, and having strong applicability.

[0039] Furthermore, in order to make the paving position more accurate, the clamping mechanism 110 is provided with a lateral position sensor 114 connected to the paving drive assembly 220. The lateral position sensor 114 is used to detect the lateral position of the first clamp 111 and the second clamp 112. The signal of the lateral position sensor 114 is transmitted to the paving drive assembly 220. The paving drive assembly 220 drives the movable frame 211 to move laterally according to the signal, so that the circle enclosed by the multiple flexible pressure strips 212 on the top projection plane is coaxial with the annular reinforcement sheet 700, and the paving shaping effect of each position of the annular reinforcement sheet 700 is consistent. At the same time, the position of the multiple flexible pressure strips 212 on the movable frame 211 is slidably adjusted to adapt to the size of the hydrogen storage cylinder 500.

[0040] Furthermore, the paving drive assembly 220 of this embodiment includes a Z-axis drive structure, a Y-axis drive structure and an X-axis drive structure to realize the movement of the moving frame 211 in the up-down direction and the horizontal direction.

[0041] The paving module 200 of this embodiment also includes a positioning mechanism 230, which is used to position the clamped hydrogen storage cylinder 500. The positioning mechanism 230 includes a positioning rod 231, which is vertically connected to the bottom of the movable frame 211 and is located at the center of the multiple flexible pressure strips 212. Specifically, the positioning rod 231 is a telescopic driving rod structure, and a sleeve 232 is provided at the lower end. 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 together with the clamping module 100, the hydrogen storage cylinder 500 is positioned and fixed.

[0042] Furthermore, the positioning rod 231 is provided with a longitudinal sensor, which is used to detect the telescopic length of the positioning rod 231. The longitudinal position sensor 233 is connected to the paving drive assembly 220. The signal of the longitudinal position sensor 233 is transmitted to the paving drive assembly 220. The paving drive assembly 220 controls the up and down movement of the movable frame 211 according to the signal. The lowering position of the movable frame 211 needs to be maintained within a range so that the multiple flexible pressure strips 212 can cover the entire annular reinforcement sheet 700. At the same time, the movable frame 211 does not contact the hydrogen storage cylinder 500 to avoid mutual collision and damage to the hydrogen storage cylinder 500 or damage to the paving shaping assembly 210.

[0043] Specifically, due to the special structure of the sleeve 232, during the descent of the movable frame 211, the upper-level structure of the sleeve 232 extends into the lower-level structure, and the longitudinal sensor detects the distance between each level of the sleeve 232 in the height direction. When the height distance between each level of the sleeve 232 is zero, that is, when the bottom ends of each level of the sleeve 232 overlap in height, the movable frame 211 stops moving downward.

[0044] The hydrogen storage cylinder head reinforcement device of this embodiment also includes a frame, which is arranged at the clamping station 122. The frame includes a top beam and a plurality of support columns, and the plurality of support columns are vertically connected to the bottom of the top beam. Figure 1 As shown, the paving drive assembly 220 is connected to the top beam, and the first clamping block 111 and the second clamping block 112 are connected to the bottom end of the support column through the clamping drive assembly 113 respectively.

[0045] The present invention also proposes a control method, which is applicable to the above-mentioned hydrogen storage cylinder head reinforcement device, and the control method comprises the following steps: Step S100: conveying the prepreg 600 to the cutting station 322, and cutting the prepreg 600 into annular reinforcement sheets 700 by the cutting module 300; Step S200: transferring the annular reinforcing sheets 700 one by one to the shoulder position of the hydrogen storage cylinder 500 to be reinforced, and then transporting the hydrogen storage cylinder 500 to the clamping station 122; Step S300: clamping and fixing the hydrogen storage cylinder 500; Step S400 : driving the plurality of flexible pressure strips 212 to move, contact the annular reinforcing sheet 700 and apply pressure thereto, until the annular reinforcing sheet 700 fits against the shoulder of the hydrogen storage cylinder 500 .

[0046] In step S100, the second conveying mechanism 320 is controlled to convey the prepreg 600 from the second feed end 321 to the cutting station 322, and the cutting drive 312 controls the annular die 311 to press down and cut to obtain the annular reinforcement sheet 700. After the cutting is completed, the annular die 311 moves up and returns to the initial position, and the second conveying mechanism 320 is controlled to transfer the annular reinforcement sheet 700 to the second discharge end 323. At the same time, the uncut prepreg 600 is conveyed from the second feed end 321 to the cutting station 322.

[0047] In step S200, the transfer drive mechanism 420 drives the grasping mechanism 410 to move to the second discharge end 323. After the grasping mechanism 410 grasps the annular reinforcement sheet 700, the transfer drive mechanism 420 drives the grasping mechanism 410 to move to the first feed end 121. The first feed end 121 places the hydrogen storage cylinders 500 to be reinforced one by one. The grasping mechanism 410 places the annular reinforcement sheet 700 on the shoulder position of the hydrogen storage cylinder 500 to be reinforced. The second conveying mechanism 320 conveys the hydrogen storage cylinder 500 to be reinforced and the annular reinforcement sheet 700 to the clamping station 122.

[0048] In step S300, the first clamp 111 and the second clamp 112 are respectively driven by the clamping drive assembly 113 from both sides of the hydrogen storage bottle 500 to approach the hydrogen storage bottle 500 until the first clamp 111 and the second clamp 112 are in contact with the outer periphery of the hydrogen storage bottle 500, and the positioning rod 231 extends downward until the lower end passes through the boss interface and the hydrogen storage bottle 500 in turn and contacts the first conveying mechanism 120, thereby completing the clamping and fixation of the stored hydrogen.

[0049] In step S400, the paving drive component 220 determines the position of the hydrogen storage cylinder 500 according to the detection signal of the lateral position sensor 114, controls the lateral displacement of the movable frame 211, and controls the up and down movement position of the movable frame 211 according to the detection signal of the longitudinal position sensor 233. The multiple flexible pressure strips 212 are driven to move downward, and the multiple flexible pressure strips 212 contact the annular reinforcement sheet 700. Under the action of gravity, pressure is applied to the annular reinforcement sheet 700 to perform paving and shaping until the annular reinforcement sheet 700 fits the shoulder position of the hydrogen storage cylinder 500. After paving is completed, the paving drive component 220 controls the movable frame 211 to move upward, the positioning rod 231 retracts, the first clamping block 111 and the second clamping block 112 move away from each other, and the hydrogen storage cylinder 500 is conveyed to the first discharge end 123 by the first conveying mechanism 120.
