Description

Technical Field

[0001] This utility model relates to the field of fuel cell technology, specifically to a dust-removing and anti-static proton exchange membrane coating device. Background Technology

[0002] The membrane electrode assembly (MEA) is the core component of a fuel cell and the site of electrochemical reactions inside the cell. It consists of an ion exchange membrane, a catalyst layer, and a gas diffusion layer. To prepare the MEA, catalyst slurry is coated on both sides of the proton exchange membrane to form catalyst layers on both sides. Then, the diffusion layer is attached to the two catalyst layers respectively, and the "sandwich" style MEA is achieved through processes such as hot pressing.

[0003] In the existing technology, during the proton exchange membrane spraying operation, it is necessary to manually flip each exchange membrane, which not only affects the production efficiency of the proton exchange membrane, but also affects the positioning accuracy of the proton exchange membrane. At the same time, the existing proton exchange membrane coating equipment cannot clean the impurities attached to the proton exchange membrane, which leads to contamination of the coating operation. Utility Model Content

[0004] To address the aforementioned technical problems, this utility model provides a dust-removing and anti-static proton exchange membrane coating device.

[0005] The technical solution of this utility model is as follows: a dust removal and anti-static proton exchange membrane coating equipment, including an operating table, a fixing component disposed on the upper surface of the operating table for fixing the proton exchange membrane, a driving component disposed on the operating table, and a dust removal component and a spraying component respectively disposed on the driving component; a gantry is provided on the upper surface of the operating table;

[0006] The drive assembly includes a drive motor mounted on the upper surface of the gantry via a vertical plate, a drive screw mounted on the output end of the drive motor, a drive beam mounted on the top of the gantry, and a switching seat slidably engaged with the bottom end of the drive beam; the upper surface of the drive beam is provided with a connecting seat that penetrates the gantry and is threadedly connected to the drive screw.

[0007] The dust removal assembly includes a first bracket disposed on the bottom surface of the drive beam, a dust removal nozzle disposed at the bottom of the first bracket, a dust removal fan disposed on the upper surface of the gantry and connected to the dust removal nozzle via a pipe, and a dust collection box connected to the dust removal fan.

[0008] The spraying assembly includes a second bracket disposed on the bottom surface of the drive beam, a feed pipe disposed at the bottom of the second bracket, several spray nozzles equidistantly distributed at the bottom end of the feed pipe, a storage tank disposed on the upper surface of the gantry and connected to the feed pipe via a conduit, and a pressure pump disposed at the connection between the storage tank and the feed pipe.

[0009] Furthermore, there are two fixing components, which are respectively set on both sides of the upper surface of the operating table. The fixing components include a clamping box, a fixed engagement seat fixedly set at the bottom of the clamping box, and a movable engagement seat movably set inside the clamping box and above the fixed engagement seat. One end of the clamping box is open, and both ends of the movable engagement seat are provided with pressure seats that penetrate the clamping box and slide and engage with the clamping box. A clamping screw is threadedly connected to the outer wall of the clamping box and rotatedly engaged with the pressure seat. One of the clamping boxes is slidably engaged with the operating table through a threaded seat, and an adjusting screw that is threadedly connected to the threaded seat is rotated and engaged with the operating table.

[0010] Instructions: When using, place both ends of the proton exchange membrane between the two sets of fixed and movable clamping seats respectively. Use the adjusting screw to push the movable clamping seat to move inside the corresponding clamping box to fix the proton exchange membrane. Then rotate the screw to make the two clamping boxes move away from each other, at which point the proton exchange membrane will be stretched and flattened.

[0011] Furthermore, both clamping boxes are slidably engaged with a flipping seat at their bottom ends, and both the upper and lower ends of the clamping boxes are provided with sliding beams that can be slidably engaged with the flipping seat; a limiting seat is movably engaged with the flipping seat and slidably engaged with the outer wall of the clamping box; the limiting seat is slidably engaged with the conversion seat through a vertical rod, and a damping spring that abuts against the limiting seat is sleeved on the vertical rod; a threaded seat is provided at the bottom end of the flipping seat.

[0012] Explanation: After one end face of the proton exchange membrane is coated, pull the two clamping boxes to slide on the corresponding flipping seat, move the proton exchange membrane to the other side of the operating table, and then flip the two clamping boxes so that the other end face of the proton exchange membrane faces the coating component; thus, this utility model can realize double-sided coating of the proton exchange membrane and improve the coating efficiency of the proton exchange membrane.

[0013] Furthermore, a linkage rod is movably connected between the two clamping boxes;

[0014] Note: Using a linkage rod to move the two clamping boxes synchronously helps improve the flatness of the proton exchange membrane during flipping.

[0015] Furthermore, a grinding cylinder is rotatably engaged at the bottom of the first bracket, and a connecting pulley is provided at one end of the grinding cylinder; an auxiliary motor is provided inside the first bracket; a drive pulley is provided at the output end of the auxiliary motor; the drive pulley and the connecting pulley are connected by belt drive; two dust removal nozzles are provided, and the two dust removal nozzles are located on both sides of the grinding cylinder respectively;

[0016] Explanation: An auxiliary motor drives the drive pulley to rotate. The connection between the drive pulley and the connecting pulley causes the grinding cylinder to rotate inside the first support. The grinding cylinder polishes and cleans the contaminants attached to the surface of the proton exchange membrane. This not only improves the adhesion of the catalyst to the proton exchange membrane, but also prevents dust and other impurities from adhering to the proton exchange membrane and forming charge accumulation, thus improving the safety of fuel cell use.

[0017] Furthermore, a blower is installed at the bottom of the second bracket, and a hot air blower connected to the blower is installed on the upper surface of the gantry.

[0018] Note: Using a hot air blower to blow high-temperature air through a blower onto the sprayed proton exchange membrane helps improve the coating efficiency of the proton exchange membrane.

[0019] The working principle of this utility model is as follows:

[0020] First, place both ends of the proton exchange membrane between two sets of fixed and movable clamping seats. Use the adjusting screw to push the movable clamping seat to move inside the corresponding clamping box to fix the proton exchange membrane. Then rotate the screw to make the two clamping boxes move away from each other, at which point the proton exchange membrane is stretched and flattened.

[0021] Then, adjust the position of the switching seat on the drive beam so that the dust removal component is above the proton exchange membrane. Use the drive motor to drive the drive screw to rotate. At this time, the drive beam drives the switching seat and the dust removal component to move synchronously. The dust suction fan sucks the dust and other pollutants attached to the surface of the proton exchange membrane into the dust collection box through the dust suction nozzle. At the same time, use the auxiliary motor to drive the drive pulley to rotate. The connection between the drive pulley and the connecting pulley causes the grinding cylinder to rotate inside the first bracket. Use the grinding cylinder to grind and clean the pollutants attached to the surface of the proton exchange membrane.

[0022] Then, the spraying assembly is adjusted to be above the proton exchange membrane. The catalyst stored inside the storage tank is sprayed onto the proton exchange membrane through the feed pipe and the spray nozzle under the action of the pressure pump, forming a catalyst film on the surface of the proton exchange membrane.

[0023] Finally, using the linkage rod, the two clamping boxes are slid on the corresponding flipping seats to move the proton exchange membrane to the other side of the operating table. Then, the two clamping boxes are flipped so that the other end face of the proton exchange membrane faces the spraying assembly. The above operation is repeated to clean and spray the other side of the proton exchange membrane.

[0024] Compared with the prior art, the beneficial effects of this utility model are reflected in the following aspects:

[0025] First, the structure of this utility model is reasonably designed. It uses two sets of fixing components to clamp and fix the proton exchange membrane, so that the proton exchange membrane always remains taut and flat when the catalyst is sprayed, which is conducive to improving the consistency of the catalyst layer coating thickness.

[0026] Secondly, the fixing component of the utility model can drive the proton exchange membrane to rotate on the operating table, so that the proton exchange membrane can be sprayed on both sides after being fixed once, which improves work efficiency; at the same time, it avoids damage to the proton exchange membrane caused by multiple clamping.

[0027] Third, this utility model uses a grinding cylinder to grind and clean the dust and other pollutants attached to the surface of the proton exchange membrane, and then uses a dust suction fan to suck the ground dust and other pollutants into the dust collection box. This not only improves the adhesion effect of the catalyst on the proton exchange membrane, but also prevents dust and other impurities from adhering to the proton exchange membrane and forming charge accumulation, thereby improving the safety of fuel cell use.

[0028] Fourth, this utility model utilizes a single power unit to achieve synchronous movement of the dust assembly and the spraying assembly, effectively reducing the energy consumption of the equipment. Attached Figure Description
