Description

Technical Field

[0001] This utility model relates to the field of coating equipment technology, and in particular to a proton exchange membrane coating equipment. Background Technology

[0002] With the rapid development of fuel cell technology, the proton exchange membrane (PEM) is one of the core components of fuel cells, and its production quality and efficiency are becoming increasingly critical. The PEM coating equipment plays an important role in the production process of PEM by uniformly and accurately coating specific coatings onto the membrane surface. This not only relates to the performance of the PEM, such as ion conductivity and gas barrier properties, but also directly affects the overall performance and service life of the fuel cell. In actual production, in order to meet the production needs of PEMs with different specifications and performance requirements, high requirements are placed on the coating accuracy, flexibility and operability of the coating equipment.

[0003] Traditional proton exchange membrane coating equipment typically consists of a simple fixed coating head and a basic membrane conveying device. The coating head is generally a fixed nozzle or scraper structure located at a fixed position above the membrane conveying path. The membrane conveying device usually uses a simple roller conveyor belt to uniformly convey the proton exchange membrane through the area below the coating head at a fixed speed.

[0004] However, traditional proton exchange membrane coating equipment has serious shortcomings in terms of spraying range adjustment. Because the position of its coating head is fixed, it is impossible to flexibly adjust the spraying range according to different production needs. When producing proton exchange membranes of different sizes or requiring special coating patterns, it is difficult to accurately control the coating area, which can easily lead to coating waste or uneven coating, affecting the quality and performance of the proton exchange membrane. Therefore, a proton exchange membrane coating equipment is proposed to solve the above problems. Utility Model Content

[0005] To overcome the above shortcomings, this utility model provides a proton exchange membrane coating equipment, which aims to improve the problem in the prior art that the spraying range cannot be flexibly adjusted according to different production needs, and that it is difficult to accurately control the coating area when producing proton exchange membranes of different sizes.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0023] This utility model has the following beneficial effects:

[0024] 1.

[0032] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0033] Reference Figures 1-3 An embodiment of this utility model provides a proton exchange membrane coating device, including a frame 1 and a fixed platform 2. A conveyor belt 3 is provided inside the fixed platform 2, and the fixed platform 2 provides stable support for the conveyor belt 3. A support plate 26 is fixedly connected inside the frame 1. A motor 4 is fixedly connected to one side of the support plate 26. A rotating column 5 is fixedly connected to the output end of the motor 4. A gear 6 is fixedly connected to the outer wall of the rotating column 5. A transmission component is provided at the bottom of the fixed platform 2, and a moving component is provided on one side of the frame 1.

[0034] The transmission assembly includes a connecting frame 7, the top of which is fixedly connected to the bottom of the fixed platform 2. A rack 8 is fixedly connected to one side of the connecting frame 7, and the rack 8 meshes with a gear 6. A slider 10 is fixedly connected to one side of the fixed platform 2, and a slide rail 9 is fixedly connected to one side of the frame 1. The slider 10 is slidably connected inside the slide rail 9, allowing the slider 10 to slide smoothly in the slide rail 9. A fixed plate 12 is fixedly connected to the other side of the support plate 26. A pawl 13 is rotatably connected to one side of the fixed plate 12. A ratchet 11 is fixedly connected to the outer wall of the rotating column 5. The ratchet 11 and the pawl 13 engage with each other. The pawl 13, through its engagement with the ratchet 11, ensures the precise positioning of the rotating column 5 at a specific position.

[0035] Specifically, when using this coating equipment, the proton exchange membrane first needs to be placed above the conveyor belt 3 and transported stably by the conveyor belt 3. Throughout the process, the nozzle 25 is responsible for evenly spraying the coating onto the surface of the proton exchange membrane to achieve uniform coverage of the membrane surface coating. If it is necessary to adjust the spraying range, the rotation of the rotating column 5 can be controlled by the motor 4. When the motor 4 starts, the rotation of the rotating column 5 drives the gear 6 to rotate, and the rack 8 will undergo horizontal displacement under the push of the gear 6. The movement of the rack 8 further drives the connecting frame 7 to move accordingly. The connecting frame 7 moves from top to bottom. The movement of the rotating column 5 allows the fixed platform 2 and the conveyor belt 3 to be adjusted vertically, precisely controlling the distance between the nozzle 25 and the proton exchange membrane, thereby adjusting the size of the spraying area and ensuring the uniformity and accuracy of the coating. In addition, the outer wall of the rotating column 5 is equipped with a ratchet 11, which works in conjunction with the pawl 13. Whenever the rotating column 5 drives the ratchet 11 to rotate, the pawl 13 will rotate under the guidance of the fixed plate 12 and eventually enter the groove inside the ratchet 11 for locking, thereby ensuring that the adjusted spraying range remains stable and will not shift due to equipment vibration or external force.

[0036] Reference Figure 1 , Figure 2 and Figure 4The moving component includes a transmission belt 14 and a connecting block 15. The transmission belt 14 is located on one side of the frame 1. The connecting block 15 is fixedly connected to one side of the transmission belt 14. A slide rod 16 is slidably connected inside the connecting block 15. A pulley 17 is provided on the outer wall of the slide rod 16 to ensure that the pulley 17 can move smoothly under the guidance of the guide rail 18. The top of the frame 1 is fixedly connected to the guide rail 18. The pulley 17 is slidably connected to the outer wall of the guide rail 18. A support frame 19 is provided on the outer wall of the slide rod 16. A second motor 20 is fixedly connected to the top of the support frame 19. A turntable 21 is fixedly connected to the output end of the second motor 20. An eccentric column 22 is fixedly connected to the bottom end of the turntable 21, which enables the connecting frame 23 to generate a small lateral displacement during rotation, thereby accurately controlling the coating accuracy. A connecting frame 23 is provided on the outer wall of the eccentric column 22. A limit groove 24 is opened inside the connecting frame 23. The connecting frame 23 is slidably connected inside the limit groove 24. A nozzle 25 is fixedly connected to the bottom of the connecting frame 23.

[0037] Specifically, the coating equipment uses a drive belt 14 to move the nozzle 25 back and forth stably. The drive belt 14 operates under the drive of a motor and, through its connection with the connecting block 15, drives the connecting block 15 to move. The connecting block 15 is connected to the internal sliding rod 16. When the sliding rod 16 is under force, it drives the nozzle 25 to move smoothly back and forth along the length of the proton exchange membrane. In this way, the nozzle 25 can achieve continuous and uniform spraying coverage on the surface of the membrane. To further optimize the spraying effect, the equipment is also equipped with a second motor 20, whose output drives the turntable 21 to rotate. The rotation of the turntable 21 drives the eccentric column 22 to move along the limiting groove 24, thereby causing the connecting frame 23 to shift. Through this transmission method, the movement of the connecting frame 23 enables the nozzle 25 to reciprocate in the left and right directions on the surface of the proton exchange membrane, ensuring that the nozzle 25 can coat the membrane more evenly and uniformly, thereby improving the quality of the coating layer and avoiding uneven or excessive local spraying.

[0038] Working Principle: When using this coating equipment, the proton exchange membrane is first placed above the conveyor belt 3 and transported. During this process, the coating is sprayed onto the exchange membrane through the nozzle 25. When the spraying range needs to be adjusted, the output end of the motor 4 drives the rotating column 5 to rotate. The rotating column 5, under force, drives the gear 6 on the outer wall to rotate. The gear 6 drives the rack 8 that meshes with it to move. The rack 8, under force, drives the connecting frame 7 on one side to move, causing the connecting frame 7 to move the fixed platform 2 and the conveyor belt 3 up and down, thereby adjusting the distance between the exchange membrane and the nozzle 25. At the same time, the rotating column 5 also drives the ratchet 11 on the outer wall to rotate. When the ratchet 11 rotates, it drives the pawl 13 to rotate on one side of the fixed plate 12. When adjusting... When the desired position is reached, the ratchet 11 stops rotating, causing the pawl 13 to rotate and lock inside the ratchet 11, thus achieving the effect of adjusting the spraying range. During coating, the drive belt 14 can be driven to move, which in turn drives the connecting block 15 on one side to move. The connecting block 15 is forced to move the internal slide bar 16, which in turn causes the nozzle 25 to move back and forth above the exchange membrane. At the same time, the output end of the motor 20 drives the turntable 21 to rotate. The turntable 21 is forced to move the bottom eccentric column 22 inside the limiting groove 24, which in turn causes the connecting frame 23 to be forced to move the bottom nozzle 25 left and right reciprocatingly, making the spraying of the nozzle 25 more uniform, thus achieving the effect of uniform coating.

Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
