Description

Technical Field

[0001] This invention relates to the field of hydrogen energy battery exchange membrane processing equipment, and particularly to a hydrogen energy battery exchange membrane cutting device and method. Background Technology

[0002] Proton exchange membranes (PEMs), also known as hydrogen fuel cell membranes, are dense, ion-selectively permeable membranes. Originally used in seawater desalination and the chlor-alkali industry, they have become a key material in the new energy field in recent years, with the development of fuel cells, flow batteries, and other new energy technologies. They are widely used in water electrolysis for hydrogen production, fuel cells, and vanadium redox flow batteries. During processing, the membrane needs to be cut from a roll of membrane material, typically using a membrane cutting device. For example, patent CN217534914U discloses a rotary cutter membrane cutting device. This device actively cuts the membrane material through the relative rotation of the cutter shaft and the rotary shaft, effectively reducing burrs at the cut. Furthermore, a membrane tension adjustment component allows for adjustment of the membrane tension, ensuring the membrane remains taut after passing through the cutting component. However, existing membrane cutting devices typically require replacing the entire roll of membrane material after use, necessitating the re-drawing of the membrane material onto the cutting device, thus reducing processing efficiency. Summary of the Invention

[0012] In some embodiments, the feeding assembly, the receiving assembly, and the roll detection sensor are mounted on a support plate, and the support plate has several mounting holes.

[0013] A method for cutting a hydrogen fuel cell exchange membrane, using the aforementioned membrane cutting device, includes the following steps: S100: The film material is supplied through the feeding component, and the film material enters the roll cutting device for cutting after passing through the film component.

[0024] The specific embodiments of the present invention will be described in detail below with reference to the accompanying drawings. It should be understood that the specific embodiments described herein are for illustration and explanation only and are not intended to limit the present invention.

[0025] like Figures 1 to 5 As shown, this embodiment of a hydrogen energy battery exchange membrane cutting device includes: a feeding assembly 1 for feeding and positioning membrane material 10, which is wound and placed on a feed roller 11; a membrane passing assembly 2, located downstream of the feeding assembly 1, including a membrane passing roller 21, a counterweight roller 22, a tension detection sensor 23, and a lifting device 24, wherein the counterweight roller 22 is spaced apart from the membrane passing roller 21, and in this embodiment, the counterweight roller 22 is positioned between the two membrane passing rollers 21, thereby pressing down and tensioning the membrane material 10 between the membrane passing rollers 21; the tension detection sensor 23 is used to detect the tension of the membrane material; the lifting device 24 is connected to the counterweight roller 22, and the lifting device 24 can drive the counterweight roller 22 to rise and fall, thereby controlling the tension of the membrane material 10; and a material changing assembly 3, located below the feeding assembly 1, for changing the membrane material, whereby new material can be easily connected to old material when the membrane material on the feed roller 11 of the feeding assembly 1 is used up. A roll-cutting device 4, located downstream of the film-coating assembly 2, is used to cut the film material 10. The film material 10 enters the roll-cutting device 4 after passing through the film-coating assembly 2 and is output after cutting. A feeding assembly 5, located downstream of the roll-cutting device 4, is used for receiving the product. A receiving assembly 6, located above the feeding assembly 5, is used for waste recycling. The cut film material 10 is wound and recycled by a recycling roller 51. A roll detection sensor 7 is spaced apart from the feeding assembly 1 and the receiving assembly 6 to detect the roll diameter. A control module 8 is connected to the tension sensor 23, the lifting device 24, and the roll detection sensor 7, and controls the lifting device 24 by receiving sensor signals. In the above technical solution, the feeding assembly 1 supplies the film material 10, which is then cut by the roll-cutting device 4 after passing through the film-coating assembly 2. The membrane material can be monitored in real time by the material roll detection sensor 7. When the diameter of the membrane material in the feeding component 1 is less than the preset value, the control module 8 controls the lifting device 24 to move upward, so that the membrane material can be connected on the material changing component 3, thereby facilitating the replacement of old and new membrane materials.

[0026] In this embodiment, a hanging plate 9 is provided below the material changing component 3, which can provide initial guidance during material feeding, facilitating manual feeding and the feeding shaft. Furthermore, it can prevent the film material from falling and drifting during feeding. The hanging plate 9 has arc-shaped portions 91 at both ends for easy hanging of the film material, and the hanging plate is inclined. The lifting device 24 includes a power module 241, a sliding plate 242, a linear guide rail 243, and a positioning block 244. The power module 241 is connected to the sliding plate 242, and the two sides of the sliding plate 242 are engaged with the linear guide rail 243. The positioning block 244 is disposed on the sliding plate 242 and located below the counterweight roller 22. During manual material change, the power module 241 drives the slide plate 242 to rise until the positioning block 244 supports the counterweight roller 22. At this point, film threading is performed. After the film threading action is completed, the power module 241 drives the slide plate 242 to descend, preventing the counterweight roller from falling rapidly and damaging the product, until the positioning block 244 disengages from the counterweight roller. At this point, the film generates tension through the counterweight roller, and the equipment can operate normally. In this embodiment, the power module is a servo linear module. The slide plate 242 is provided with several spaced positioning blocks 244, each with a positioning groove 245, which can more stably support the counterweight roller. A limit sensor 221 is provided above the counterweight roller 22 to detect the position of the counterweight roller. The material changing assembly 3 includes a docking platform 31 and guide blocks 32. The guide blocks 32 are spaced apart on the docking platform 31. In this embodiment, two guide blocks 32 are provided, dividing the docking platform 31 into a first docking area 311 and a second docking area 312. During manual material changing, the film material on the hanging plate is placed on the docking platform, located in the first docking area 311. Then, the newly loaded film material joint is placed in the second docking area 312 of the guide block 32. Finally, the two material joints are connected together with tape. One end of the guide block 32 is provided with a protrusion 321. The protrusions of the two guide blocks 32 are arranged opposite each other, thereby limiting the film material joint. The feeding assembly 1, the receiving assembly 6, and the roll detection sensor 7 are mounted on the support plate 20. The support plate 20 is provided with several mounting holes 201, which facilitates the installation of the above components and allows for assembly using mounting holes at different positions according to the processing requirements.

[0027] This embodiment of a hydrogen energy battery exchange membrane cutting method includes the following steps: S100: Membrane material is supplied through the feeding component 1, the membrane material enters the rolling cutting device 4 through the membrane component 2 for cutting, the product is collected through the unloading component 5, the waste is collected through the receiving component 6, and the roll detection sensor 7 detects the diameter of the membrane roll on the receiving component 6 and the feeding component 1 in real time; S200: When the diameter of the membrane roll on the feeding component 1 is less than a preset value, the lifting device 24 is started through the control module to lift the counterweight roller 22, and the rolling cutting device 4 continues to operate until the membrane material falls on the material exchange component 3, and the rolling cutting device stops; S300: New membrane material is manually installed on the feeding component 1 and the new and old membrane materials are connected, the lifting device 24 and the counterweight roller 22 are reset, and the rolling cutting device 4 is started.
