Description
Technical Field
[0001] This invention relates to the field of equipment for fuel cell fabrication, and more particularly to a batch proton exchange membrane continuous impregnation equipment used in continuous coating equipment. Background Technology
[0002] A fuel cell is a power generation device that directly converts the chemical energy present in fuel and oxidant into electrical energy. Membrane electrode assembly (MEA) is a crucial component of a fuel cell. In practical applications of fuel cell stacks, MEAs require proton exchange membranes and anion exchange membranes. Different membranes require separate impregnation with acid or alkali solutions. In traditional impregnation processes, the prepared membrane is typically placed directly into an impregnation tank filled with acid or alkali. For large-scale membrane production, it is also done by rolling the membranes into rolls and then impregnating them in the same tanks. In batch membrane production using coating equipment, the membranes are often prepared, rolled into rolls, removed from the coating equipment, and then transported to different impregnation tanks for immersion. This process involves time-consuming and labor-intensive manual handling, impacting work efficiency. While using intelligent robotic arms for handling can shorten the time to some extent, the finished film material is relatively soft and coated with a working coating, making it quite valuable. The robotic arm's gripping method is highly likely to damage the film surface. Furthermore, the finished rolls of film are heavy and bulky, making it difficult to control their arrangement within the immersion tank when handling large quantities manually. In summary, current methods for preparing large batches of film on coating equipment cannot achieve continuous immersion in different tanks, resulting in high labor and time costs. They also cannot effectively control the arrangement of large batches of finished film within the immersion tank, thus affecting the tank's capacity and posing a risk of damage to the finished film surface. Summary of the Invention

The working frame includes multiple parallel drying plates from top to bottom. An impregnation space layer is provided between every two drying plates.

[0008] Along the conveying direction of the conveying device, the conveying device also includes a corner auxiliary component near the corner platform, so that the take-up roller enters the second conveying channel or the third conveying channel from the first conveying channel.
[0009] The present invention is further configured such that the conveyor belt on the first conveyor channel can move up and down as a whole, and can slide horizontally toward or away from the take-up roller.
[0010] The present invention is further configured such that: the corner auxiliary component includes an electric slide rail, on which a cylinder assembly slides horizontally, and a push plate that acts on the take-up roller is fixedly provided on the cylinder assembly.
[0011] The present invention is further configured such that: the corner platform achieves lifting and lowering motion at the connection points between the corner platform and the second and third conveyor tracks respectively through the rotation of the electric roller shaft assembly.
[0012] The present invention is further configured such that: the connection between the conveying device and the acid-base pool is the inlet, and the working frame is equipped with a servo motor assembly to realize horizontal sliding motion in the Y direction and lifting motion in the Z direction.

[0014] The present invention is further configured such that the conveyor belt includes, from the inside out, a metal support layer, an electromagnetic sheet positioning layer, and a thin film protective layer.
[0015] The present invention is further configured such that: a blower system is provided on the drying plate; the blower system includes an air source pipe, an electric switch valve is provided on the air source pipe, a pre-purging assembly is provided between the electric switch valve and the drying plate, the pre-purging assembly includes a pressurizing fan, a one-way valve and a branch pipe connected to the air source pipe, the one-way valve is provided on the branch pipe.
[0016] Compared with the prior art, the present invention has the following advantages:
[0017] 1. This invention addresses existing roll-to-roll coating equipment by adding a rear-end impregnation device. The rewinding roller designed in this invention can be quickly installed and removed from the coating equipment. That is, after the finished coated film is wound up on the rewinding roller, the rewinding roller can be directly removed from the coating equipment and conveyed to the acid and alkali tank for immersion via a conveying device. The conveying device uses a self-driven conveyor belt, and the rewinding roller can maintain its relative position on the conveyor belt and be conveyed to the acid and alkali tank. This avoids manual handling and robotic arm handling, effectively reducing damage to the surface of the finished roll material.
[0018] Furthermore, this invention features a working frame with multiple impregnation spaces within the acid / alkali tank, enabling the orderly immersion of multiple take-up rollers carrying finished films within the working frame. Additionally, through an electric drive mechanism and traction rollers, the take-up rollers are quickly installed within the working frame via the electric drive mechanism, which simultaneously rotates the take-up rollers. After the operator winds the other end of the finished film from the take-up roller onto the traction roller, the synchronous clockwise rotation of the traction and take-up rollers achieves the unfolding and conveying of the finished film within the impregnation spaces. This means the finished film can be unfolded and conveyed while being impregnated within the acid / alkali tank, resulting in better and more complete impregnation efficiency, depth, and effectiveness, while also significantly reducing impregnation time. Moreover, the traction and take-up rollers can also rotate counter-clockwise synchronously, enabling the cyclical conveying of the finished film within the impregnation spaces, further enhancing the impregnation effect.
[0019] Furthermore, this invention features multiple take-up rollers, enabling simultaneous coating preparation along one line, as well as simultaneous immersion in acid and alkali solutions, effectively reducing time costs. This allows for the production of large quantities of roll film on coating equipment, and subsequent continuous immersion processes in different impregnation tanks.
[0020] 2. The conveying device designed in this invention is divided into several parts. First, it uses a first conveyor with lifting and horizontal sliding functions to move and adjust its position directly below each take-up roller. This allows workers to easily place the take-up rollers onto the first conveyor with minimal effort after disconnecting the power and removing them. Then, the first conveyor connects to a corner platform via horizontal sliding movement. The take-up rollers on this platform are then conveyed to the corner platform by a conveyor belt. With the help of a corner auxiliary component at the corner platform, the take-up rollers are pushed onto a second or third conveyor. Finally, they are connected to the acid solution. The inlets of the tank or alkaline tank are connected. The workers quickly install the winding roller into the impregnation space layer of a certain layer, thereby realizing the orderly arrangement and storage of the finished membrane in the impregnation space layer, and subsequent unfolding conveying and unfolding immersion processes. This invention addresses the characteristic that the membrane of the product in the fuel cell field is relatively easy to be damaged. The conveying device is designed to solve the problem of how the conveying device can connect with the impregnation tank to smoothly convey large-volume and heavy finished rolls to the acid and alkali tanks through the combined action of multiple areas and the combination of self conveying method, as well as the design of branch channels that can simultaneously enter two impregnation tanks.
[0021] 3. The working frame of this invention is controlled by a servo motor to achieve multi-directional displacement. That is, the servo motor can achieve fixed-distance displacement movement through the control program, so that each layer of the working frame is exactly aligned with the inlet, which facilitates the installation of the winding roller. The electrical components are simple to control, and the operation is simple and efficient.
[0022] 4. The corner platform of the present invention can be lifted and lowered by the electric roller shaft assembly, that is, it can swing with a certain height in the left and right directions. When a large volume and heavy take-up roller is conveyed to the corner platform, the corner auxiliary component pushes the take-up roller while the height of the corner platform helps the take-up roller to enter the second or third conveyor track more smoothly under its own gravity.
[0023] 5. The present invention adds a strip-shaped air outlet for side blowing, that is, combined with the soaking method of finished film conveying, when it is in the unfolded state, the side strip-shaped air outlet blows air to match the shape of the unfolded side (section) of the finished film, and the turntable equipped with the air outlet can be rotated and adjusted. The operator can adjust the inclination of the strip-shaped air outlet according to the curvature of the side of the unfolded finished film to better match the finished film, so as to more effectively and powerfully blow air to dry the finished film without putting too much pressure on the finished film;
[0024] 6. The conveyor belt of the present invention has a multi-layer structure. First, the metal support layer forms a good bottom layer with strong support. Then, the electromagnetic sheet positioning layer realizes the electromagnetic adsorption of the take-up roller, so that the take-up roller will not roll off the conveyor. Finally, the film protective layer serves as the top layer and directly contacts the take-up roller containing the finished film, without causing any contact damage to the finished film.
[0025] 7. Each impregnation space layer in the working framework of this invention is equipped with a drying plate. That is, after the impregnation is completed, the finished film, which is still in the unfolded conveying state, can be dried by the drying of each layer. In this state, the finished film has a better and faster drying effect, and it can also be thoroughly dried multiple times through the cyclic conveying of the finished film. In addition, the blowing system of the drying plate is designed with a pre-purging component and an electric switch valve, etc. On the one hand, it prevents liquid from entering the blowing system. On the other hand, before the drying plate is working, the pre-purging component can pressurize and blow dry the air source pipe of the drying plate, ensuring that the air source pipe is clean, free of impurities and dry, thus avoiding contamination of the finished film.

[0035] Example 1
[0036] A batch proton exchange membrane continuous impregnation device for use in continuous coating equipment, such as Figure 1As shown in Figure 2, the continuous coating equipment is a common piece of equipment in the existing field. It mainly includes a frame, a coating area 1, and a PLC system. The coating area 1 includes a transmission roller assembly for tensioning and winding the roll film. The transmission roller assembly includes a take-up roller 2 located at the tail end of the conveyor to perform the winding process of the coated finished film. In this invention, multiple take-up rollers 2 are used. In this embodiment, there are specifically three take-up rollers 2, arranged in an array from high to low. Each take-up roller 2 is quickly assembled and disassembled by an electromagnet mechanism 2-1. The electromagnet mechanism 2-1 uses a commonly used electromagnet in the existing field and a control circuit connected to the PLC system circuit signal. That is, the energization and de-energization of the electromagnet can be directly controlled by the PLC system to achieve the rapid assembly and disassembly of the take-up roller 2 on the equipment. Figure 1 Or as shown in Figure 2.
[0037] like Figure 1 As shown in Figure 2, this impregnation equipment includes a conveying device 3 and an acid-alkali tank 4. The acid-alkali tank 4 includes an acid tank 4-1 for holding acid and an alkali tank 4-2 for holding alkali. The conveying device 3 is connected to the PLC system circuit signal of the continuous coating equipment. It includes a first conveyor channel communicating with the take-up roller 2. A corner platform 3-4 is provided at one end of the first conveyor channel away from the take-up roller 2. A second conveyor channel and a third conveyor channel perpendicular to the first conveyor channel are respectively provided at both ends of the corner platform 3-4. The acid tank 4-1 and the alkali tank 4-2 are also included. -2 are respectively distributed at the ends of the second and third conveyor channels away from the corner platform 3-4; the first, second, and third conveyor channels all include self-driving conveyor belts 3-5. The conveyor belts 3-5 themselves are equipped with servo motor components commonly used in the field, so their specific structure will not be described in detail here. In addition, the conveyor belts 3-5 include, from the inside out, a metal support layer 3-5-1, an electromagnetic plate positioning layer 3-5-2, and a thin film protective layer 3-5-3, such as... Figure 4 As shown, the electromagnetic plate positioning layer 3-5-2 is energized and de-energized by a PLC system.
[0038] like Figure 1 As shown in Figure 2, along the conveying direction of the conveying device 3, the conveying device 3 also includes a corner auxiliary component 3-6 near the corner platform 3-4 to help the winding roller 2 enter the second or third conveying channel from the first conveying channel.
[0039] The conveyor belt 3-5 of the first conveyor channel is driven by a solenoid valve mechanism 3-1-1 to achieve overall lifting and lowering movement, as well as horizontal sliding movement towards or away from the take-up roller 2. Figure 1As shown in Figure 2, the solenoid valve drive mechanism 3-1-1 adopts a conventional design in the electromechanical field, including a solenoid valve, a drive cylinder, an electric slide rail slider assembly, etc. The solenoid valve drive mechanism 3-1-1 is also connected to the PLC system circuit signal, that is, the lifting and displacement of the conveyor belt 3-5 is controlled by the signal control of the PLC system, so that it can be better close to the take-up roller 2, so that the take-up roller 2 can fall on the conveyor belt 3-5 and then be conveyed to the corner platform 3-4.
[0040] Corner platform 3-4 is a platform located at the end of the first teleportation channel, such as... Figure 1 and 2 As shown, it includes a support base 3-4-2, a working platform 3-4-3, etc. The working platform 3-4-3 can swing left and right by the electric roller shaft assembly 3-4-1 to better connect the corner platform 3-4 with the second and third conveyor tracks. The electric roller shaft assembly 3-4-1 also adopts a conventional design in the electromechanical field, including an electric roller shaft driven by a motor. The working platform 3-4-3 is connected to the electric roller shaft, and the swinging process is realized by rotating the electric roller shaft at a certain angle. At the same time, the electric roller shaft assembly 3-4-1 is also connected to the PLC system circuit signal, that is, the swinging direction of the working platform 3-4-3 is controlled by the signal control of the PLC system, that is, the connection between the working platform 3-4-3 and the second or third conveyor track is controlled.
[0041] Further corner auxiliary components 3-6 are also conventional electric components in the electromechanical field and are also connected to the PLC system circuit signals, such as... Figure 1 As shown, it includes an electric slide rail 3-6-3, on which a cylinder assembly 3-6-1 slides horizontally. A push plate 3-6-2 that acts on the take-up roller 2 is fixedly installed on the cylinder assembly 3-6-1. That is, the sliding and telescopic movements of the cylinder assembly 3-6-1 are controlled by the signal control of the PLC system, which can realize the pushing process of the take-up roller 2 placed on the corner platform 3-4.
[0042] like Figure 1 As shown in Figure 2, one end of the second and third conveyor channels is connected to both sides of the corner platform 3-4, and the other end of the second and third conveyor channels is connected to the acid pool 4-1 and the alkali pool 4-2, respectively.
[0043] like Figure 1-3As shown, both acid tank 4-1 and alkali tank 4-2 are equipped with working frames 5. The working frames 5 move horizontally within the acid and alkali tanks 4, controlled by servo motors and electric slide rails. Simultaneously, the working frames 5 themselves are also raised and lowered by servo motors, screw assemblies, etc. (not shown in the figure). All these electrical components are controlled by a PLC system for intelligent and orderly management. Furthermore, the working frame 5 includes multiple parallel drying plates 5-1 with air vents, arranged from top to bottom. Each drying plate 5-1 has an impregnation space layer 5-2 between it. Each impregnation space layer 5-2 contains an electric drive mechanism 5-3 for mounting and rotating the take-up roller 2, connected to the PLC system circuit signal. The impregnation space also contains a traction roller 5-4, driven by the electric drive mechanism 5-3 and parallel to the take-up roller 2. The electric drive mechanism 5-3 is an integration of a motor assembly and a solenoid valve assembly, enabling electromagnetic adsorption of the take-up roller 2 for rapid installation. Afterward, the rotation of the take-up roller 2 can be controlled. Figure 1-3 As shown, the electric mechanism assembly and the blower system 6 are both integrated into the electrical box 5-9 of the working frame 5.
[0044] like Figure 5 As shown, the blower system 6 of the drying plate 5-1 with air outlets includes an air source pipe 6-1 connected to the main blower 6-4. An electric switch valve 6-2 is installed on the air source pipe 6-1. A pre-purging assembly 6-3 is installed between the electric switch valve 6-2 and the drying plate 5-1. The pre-purging assembly 6-3 includes a pressurizing blower 6-3-1, a one-way valve 6-3-2, and a branch pipe 6-3-3 connected to the air source pipe 6-1. The one-way valve 6-3-2 is installed on the branch pipe 6-3-3. Additionally, as shown... Figure 3 As shown, on the working frame 5, opposite the inlet 5-5, there is an electromagnetic switch door 5-6. A sealing strip is installed inside the electromagnetic switch door 5-6 to ensure a seal after closing. In addition, a turntable 5-7 is provided on the electromagnetic switch door 5-6, and the turntable 5-7 is arrayed with strip-shaped air outlets 5-8 that are connected to the air source.
[0045] The specific implementation method includes the following steps:
[0046] S1. The finished film is wound up on take-up roller 2;
[0047] S2. The PLC system controls the conveyor belt 3-5 of the first ramp to rise and slide to a position directly below the take-up roller 2. Then, the electromagnet mechanism 2-1 is de-energized, the take-up roller 2 is quickly removed from the coating equipment and falls onto the conveyor belt 3-5 of the first ramp. Then, the conveyor belt 3-5 realizes self-transmission and slides as a whole towards the corner platform 3-4.
[0048] S3. The take-up roller 2 is conveyed onto the corner platform 3-4, and the working platform 3-4-3 is slightly tilted by the operation of the electric roller shaft assembly 3-4-1. At the same time, it is pushed into the second conveyor by the drive of the corner auxiliary assembly 3-6.
[0049] S4. The conveyor belt 3-5 of the second conveyor channel is controlled to achieve self-transmission, so as to convey the winding roller 2 to the inlet 5-5 of the acid pool 4-1.
[0050] S5. At the same time, the PLC system controls the operation of several servo motors, thereby precisely controlling the lifting and sliding movements on the working frame 5, so that its empty impregnation space layer 5-2 is connected to the inlet 5-5.
[0051] S6. Staff can approach the inlet 5-5 via the steps and quickly install the take-up roller 2 onto the electric drive mechanism 5-3 in the impregnation space layer 5-2.
[0052] S7. The staff can access the other side of the acid tank 4-1 via the steps, open the electromagnetic switch door 5-6, and wind one end of the finished film on the take-up roller 2 onto the traction roller 5-4, and then close the electromagnetic switch door 5-6.
[0053] S8, the PLC system controls the synchronous clockwise rotation of the take-up roller 2 and the traction roller 5-4, which realizes the impregnation process of the finished film in the acid tank 4-1 in an unfolding and continuous circulation process. When the finished film on the take-up roller 2 is about to be finished, the PLC system controls the take-up roller 2 and the traction roller 5-4 to rotate counterclockwise, thereby realizing the reverse transmission of the finished film. That is, the finished film can realize multiple circulation transmission processes in the impregnation space layer 5-2.
[0054] S9. After 10 hours, the impregnation work is completed. The acid in the acid tank 4-1 is extracted. The PLC system controls the blower system 6 to open. At the same time, the turntable 5-7 on the electromagnetic switch door 5-6 is rotated so that the strip-shaped air outlet 5-8 on the turntable 5-7 is parallel to the side of the unfolded finished film.
[0055] S10. First, control the pre-purge component 6-3 to ensure that the air source pipe is clean and dry. Then, the blower system 6 works to simultaneously blow hot air onto the finished film that is already in the impregnation process, so as to realize the drying process of the finished film that has completed the impregnation process.
