Description

Technical Field

[0001] This invention relates to the field of fuel cell membrane electrode manufacturing technology, and more specifically, to a method and apparatus for manufacturing membrane electrode frames. Background Technology

[0002] The membrane electrode assemblies (MEAs) of existing fuel cells typically consist of a catalyst-coated membrane (CCM), anode and cathode frames, and anode and cathode gas diffusion layers (GDLs). The anode and cathode frames include frame membranes processed into a specific shape to encapsulate the anode and cathode sides of the CCM, used to fix the CCM and define the reaction zone. The frame membranes in the fuel cell stack play a role in preventing gas leakage and insulating between the sheets. The frame membranes are usually made of frame membrane composite membranes, which include frame membranes and protective membranes bonded together.

[0003] Currently, the processing of frame films typically involves using a custom-made frame die to cut a frame film composite film with an adhesive backing film (i.e., the frame film composite film consists of three layers from top to bottom: frame film, protective film, and backing film) into a specific shape for final forming. The cutting waste is rolled up with the adhesive backing film (i.e., it moves and is subsequently stored with the adhesive backing film). The waste in the active area (i.e., the waste generated during cutting) needs to be separated using an adhesive waste removal film (i.e., separating the waste in the active area from the formed frame) and discharged. The entire manufacturing process involves the use of various auxiliary materials and the cutting and unwinding of waste materials, resulting in a large number of equipment required and a complex manufacturing process, which is not conducive to the large-scale and efficient production of frame films. In addition, existing technologies typically use a die structure when cutting the frame film composite film to a set shape, i.e., using a custom-shaped die to cut the frame film composite film. However, the customization and debugging cycle of the die structure is long, and once the die structure is determined, it can only cut frame films corresponding to the die shape, which cannot flexibly adapt to the processing needs of frame films of various shapes. Summary of the Invention

[0004] This invention provides a method and apparatus for manufacturing membrane electrode frames, which solves the problem that the manufacturing process of frame films in the prior art is complex and requires a lot of equipment, resulting in low production efficiency of frame films.

[0005] To address the aforementioned problems, according to one aspect of the present invention, a method for manufacturing a membrane electrode frame is provided, comprising the following steps: a cutting step: cutting the frame composite film to separate the frame film adhered to the protective film into a base waste film, a molded frame film, and an active area waste film, and to give the molded frame film a predetermined shape; the cutting depth is greater than the thickness of the frame film and less than the total thickness of the frame film and the protective film, so that the protective film does not break; a first separation step: simultaneously separating the molded frame film and the active area waste film from the protective film, with the base waste film remaining on the protective film; a second separation step: separating the molded frame film from the active area waste film to obtain an independently existing molded frame film; and a storage step: simultaneously rolling up and storing the base waste film and the protective film, and storing the independently existing active area waste film obtained in the second separation step.

[0006] Furthermore, the border film selected in the cutting step is a low initial tack border film; in the low initial tack border film, the initial tack between the border film and the protective film is <1.5g / 25mm.

[0007] Furthermore, the first separation step includes: setting the cut molding frame film to surround the waste film of the active area; causing the cut molding frame film to produce a burr that separates from the protective film; after pasting the burr to a fixed position, pulling the protective film away from the fixed position to separate the molding frame film and the waste film of the active area from the protective film simultaneously.

[0008] Furthermore, the second separation step includes: attaching the molded frame film and the active area waste film, which have already been separated from the protective film, to a fixed position, and using adsorption to pick up the active area waste film so as to separate the active area waste film from the molded frame film.

[0009] Furthermore, the membrane electrode frame manufacturing method also includes a feeding step, which includes: transporting the frame composite film to a designated position by rotating rollers for a cutting step; the membrane electrode frame manufacturing method also includes a transport step, which is set between the cutting step and the first separation step; the transport step includes: transporting the cut frame composite film to a designated position by rotating rollers for a first separation step.

[0010] According to another aspect of the present invention, a membrane electrode frame manufacturing apparatus is provided, which applies the above-described membrane electrode frame manufacturing method. The membrane electrode frame manufacturing apparatus includes a cutting mechanism, a peeling assembly, and a separation assembly. The cutting mechanism cuts the frame composite film to obtain a shaped frame film with a predetermined shape, thereby separating the base waste film, the shaped frame film, and the active area waste film. The peeling assembly cooperates with the separation assembly to simultaneously separate the shaped frame film and the active area waste film from the protective film and transport them to the separation assembly. The separation assembly is used to separate the shaped frame film from the active area waste film.

[0011] Furthermore, the cutting mechanism is an automatic cutting machine or a die-cutting machine.

[0012] Furthermore, the membrane electrode frame manufacturing apparatus also includes a feeding roller assembly and a receiving roller assembly. The feeding roller assembly is used to transport the frame composite film to the cutting mechanism for cutting. The receiving roller assembly is used to roll up and store the base waste film and protective film after they have been separated from the formed frame film and the active area waste film. One end of the frame composite film is rolled up on the feeding roller assembly, and the other end passes through the peeling assembly and rolls up with the receiving roller assembly. The feeding roller assembly and the receiving roller assembly rotate simultaneously, driving the frame composite film to move as a whole on the cutting mechanism and the peeling assembly.

[0013] Furthermore, the peeling assembly includes a first clamping and fixing structure, a second clamping and fixing structure, and a peeling platform. The peeling platform carries the cut border composite film and is movably disposed to move relative to the separation assembly. The second clamping and fixing structure is disposed on the peeling platform to follow the movement of the peeling platform. The first clamping and fixing structure is fixedly disposed. Both the first clamping and fixing structure and the second clamping and fixing structure are used to fix the border composite film.

[0014] Furthermore, the peeling platform has an initial state and a separation state; the two ends of the portion of the frame composite film on the peeling platform are a fixed end and a separation end, respectively; when the peeling platform is in the initial state, the first clamping and fixing structure is in the open state, and the second clamping and fixing structure is in the clamping state, so as to fix the fixed end of the frame composite film on the peeling platform. The take-up roller assembly reverses so that the portion of the frame composite film located between the separation end and the take-up roller assembly becomes longer. The longer portion is a redundant portion, and the length of the redundant portion is not less than the displacement length of the peeling platform moving towards the separation assembly; the peeling platform moves above the separation assembly and drives the forming... A portion of the border film and / or a portion of the active zone waste film are bonded and fixed to a portion of the separation assembly; when the peeling platform is in the separation state, the peeling platform moves away from the separation assembly, driving the protective film to move, so that the formed border film and the active zone waste film are simultaneously separated from the protective film, ultimately causing the formed border film and the active zone waste film to be bonded and fixed to the separation assembly; after the formed border film and the active zone waste film are separated from the protective film, the first clamping and fixing structure is in the clamping state, the second clamping and fixing structure is in the open state, and the take-up roller assembly rotates forward to drive the base waste film and the protective film to be rolled up and stored at the take-up roller assembly.

[0015] Furthermore, the stripping platform includes a platform body and a wedge, with the wedge fixedly disposed at one end of the platform body near the separation component; the frame composite membrane slides along the surfaces of the platform body and the wedge; the wedge has a sharp corner, at which the formed frame membrane and / or the active area waste membrane develop burrs, which separate from the protective membrane; wherein, the stripping platform moves closer to the separation component, causing the burrs to adhere and be fixed to a portion of the separation component; the stripping platform moves away from the separation component, causing the protective membrane to move, so that the formed frame membrane and the active area waste membrane separate from the protective membrane.

[0016] Furthermore, the membrane electrode frame manufacturing apparatus also includes a floating roller assembly, which is disposed between the peeling platform and the cutting mechanism and rolls in cooperation with the frame composite film; the floating roller assembly can be raised and lowered, and at least a portion of the gravity is applied to the frame composite film so that a portion of the frame composite film is suspended; when the peeling platform moves closer to the separation component, the distance between the peeling platform and the cutting mechanism increases, the peeling platform drives the suspended frame composite film to move, and drives the floating roller assembly to rise.

[0017] Furthermore, the membrane electrode frame manufacturing apparatus also includes a first pressure roller, a second pressure roller, and a first guide roller; the first pressure roller, the second pressure roller, and the first guide roller are rotatably disposed between the peeling platform and the cutting mechanism, with the first guide roller disposed closer to the peeling platform and the first and second pressure rollers disposed closer to the cutting mechanism; the first and second pressure rollers are disposed vertically correspondingly and roll in cooperation with the upper and lower surfaces of the frame composite film, respectively, and the first and second pressure rollers rotate in opposite directions to simultaneously flatten the frame composite film after it has been cut by the cutting mechanism; the floating roller assembly abuts against the frame composite film flattened by the first and second pressure rollers to apply at least a portion of the gravity to the frame composite film; the first guide roller is used to guide the frame composite film passing through the floating roller assembly to the peeling platform.

[0018] Furthermore, the separation component includes a robotic arm and a material platform, with the robotic arm movably positioned above the material platform. The molded border film and the active zone waste film, separated from the protective film, are adhered to the material platform. The robotic arm works in conjunction with the active zone waste film on the material platform to separate the active zone waste film from the molded border film, and the robotic arm moves the active zone waste film, which has been separated from the molded border film, to a designated location for collection. The separation component also includes a waste bin for collecting the active zone waste film that has been separated from the molded border film. The robotic arm includes a movable robotic arm and an adsorption structure mounted on the robotic arm. The adsorption structure adsorbs the active zone waste film located on the material platform and releases the adsorbed active zone waste film into the waste bin.

[0019] Furthermore, the feeding roller assembly includes a feeding drive motor, a feeding roller and a second guide roller, both rotatably arranged. The feeding drive motor drives the feeding roller to rotate, and the feeding roller engages with one end of the frame composite film to drive the frame composite film to move. The second guide roller engages with the frame composite film to guide the frame composite film that has passed through the feeding roller to the cutting mechanism. The receiving roller assembly includes a receiving drive motor, a third guide roller and a receiving roller, both rotatably arranged. The receiving drive motor drives the receiving roller to rotate, and the receiving roller engages with the other end of the frame composite film to drive the frame composite film to move. The third guide roller engages with the frame composite film to guide the basic waste that has passed through the peeling assembly to the cutting mechanism. The film and protective film are guided to the take-up roller for winding and storage. The take-up roller assembly also includes a fourth guide roller, a third pressure roller, and a fourth pressure roller. The third pressure roller, the fourth pressure roller, and the fourth guide roller are rotatably disposed between the third guide roller and the take-up roller, with the fourth guide roller positioned closer to the take-up roller and the third and fourth pressure rollers positioned closer to the third guide roller. The third and fourth pressure rollers are positioned vertically and vertically, respectively, and roll in cooperation with the upper and lower surfaces of the frame composite film. The third and fourth pressure rollers rotate in opposite directions to simultaneously flatten the base waste film and protective film that have passed through the third guide roller. The fourth guide roller is used to guide the base waste film and protective film flattened by the third and fourth pressure rollers to the take-up roller.

[0020] Applying the technical solution of this invention, this invention provides a method for manufacturing a membrane electrode frame, comprising the following steps: a cutting step: cutting the frame composite film to separate the frame film adhered to the protective film into a base waste film, a molded frame film, and an active area waste film, and giving the molded frame film a predetermined shape; the cutting depth is greater than the thickness of the frame film and less than the total thickness of the frame film and the protective film, so that the protective film does not break; a first separation step: separating the molded frame film and the active area waste film from the protective film simultaneously, with the base waste film remaining on the protective film; a second separation step: separating the molded frame film from the active area waste film to obtain an independently existing molded frame film; a storage step: simultaneously rolling up and storing the base waste film and storing the independently existing active area waste film obtained in the second separation step.

[0021] This invention, through a specially designed cutting step, allows for the efficient separation of the base waste film, the formed border film, and the active area waste film from the frame film, ensuring the formed border film maintains its intended shape. Furthermore, it ensures that the base waste film, the formed border film, and the active area waste film are individually bonded and fixed to the protective film. This allows the base waste film, the formed border film, and the active area waste film to move along with the protective film as a whole. In this case, the protective film can function as the additional support film required in existing technologies. Therefore, this invention, through a redesigned cutting method, eliminates the need for support films and other auxiliary materials, thereby saving subsequent processing steps and techniques for auxiliary materials, effectively simplifying the manufacturing process of the frame film, and saving costs. The invention reduces the need for equipment, thereby improving the production efficiency of the border film. By setting up a first separation step, a second separation step, and a collection step, it achieves both automatic forming of the border film and reliable recycling of waste materials. The method of this invention differs significantly from existing technologies in terms of the cutting and forming method of the border composite film, the separation method of the border film, and the waste discharge method. Furthermore, the method and required equipment of this invention are simpler, easier and more efficient to implement, and suitable for large-scale promotion and use. In the subsequent cutting step, existing automatic cutting machines can be used to quickly change the border film of different sizes and shapes according to different drawings, better meeting the diverse production needs of the border film.

[0037] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. The following description of at least one exemplary embodiment is merely illustrative and is in no way intended to limit the present invention or its application or use. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0038] like Figures 1 to 3 As shown, an embodiment of the present invention provides a method for manufacturing a membrane electrode frame, comprising the following steps: a cutting step: cutting the frame composite film 1 to separate the frame film adhered to the protective film into a base waste film 2, a molded frame film 3, and an active area waste film 4, and making the molded frame film 3 have a set shape; the cutting depth is greater than the thickness of the frame film and less than the total thickness of the frame film and the protective film, so that the protective film does not break; a first separation step: separating the molded frame film 3 and the active area waste film 4 from the protective film simultaneously, and leaving the base waste film 2 on the protective film; a second separation step: separating the molded frame film 3 from the active area waste film 4 to obtain an independently existing molded frame film 3; a storage step: rolling up and storing the base waste film 2 and the protective film simultaneously, and storing the independently existing active area waste film 4 obtained in the second separation step.

[0039] This invention, through a redesigned cutting step, allows for the efficient separation of the base waste film 2, the formed border film 3, and the active area waste film 4 from the frame film, ensuring that the formed border film 3 has a predetermined shape. Furthermore, it ensures that the base waste film 2, the formed border film 3, and the active area waste film 4 are respectively bonded and fixed to the protective film. This allows the base waste film 2, the formed border film 3, and the active area waste film 4 to move along with the protective film as a whole. In this case, the protective film can function as the additional support film required in existing technologies. Therefore, this invention, through a redesigned cutting method, eliminates the need for support films and other auxiliary materials, thereby saving subsequent processing steps and processes for auxiliary materials and effectively simplifying the manufacturing of the frame film. The process is streamlined and saves on required equipment, thereby improving the production efficiency of the border film. By setting a first separation step, a second separation step, and a collection step, both automatic forming of the border film and reliable recycling of waste materials are achieved. The method of this invention is significantly different from the existing technology in terms of the cutting and forming method of the border composite film 1, the separation method of the border film, and the waste discharge method. Moreover, the method and required equipment of this invention are simpler, easier and more efficient to implement, and suitable for large-scale promotion and use. In the subsequent cutting step, an existing automatic cutting machine can be used to quickly change the border film of different sizes and shapes according to different drawings, better meeting the diverse production needs of the border film.

[0040] It should be noted that: such as Figure 3 As shown, the frame composite film 1 in this invention includes a frame film and a protective film that are bonded and fixed to each other, with the frame film located above the protective film; before the first separation step, the base waste film 2, the molded frame film 3, and the active area waste film 4 are bonded and fixed to the protective film respectively; after the first separation step, the molded frame film 3 and the active area waste film 4 are both separated from the base waste film 2.

[0041] By comparing with the prior art, it can be found that the manufacturing process of the frame film in the prior art usually requires a winding and unwinding device to control the winding and unwinding of the adhesive film. The adhesive film is used to transport the frame composite film 1. The present invention can achieve the transportation of the formed frame film 3 by relying only on the protective film of the frame composite film, without the need to use an adhesive film winding and unwinding device.

[0042] Optionally, the border film used in the cutting step is a low initial tack border film; in the low initial tack border film, the initial tack between the border film and the protective film is <1.5g / 25mm. By setting the border film to a low initial tack border film, the smoothness of the film separation in the first and second separation steps is ensured, and the subsequent peeling of the border film from the protective film does not firmly adhere to the material platform 42.

[0043] Specifically, the first separation step includes: setting the cut molding frame film 3 to surround the active area waste film 4; creating a burr on the cut molding frame film 3 to separate it from the protective film; attaching the burr to a fixed position; and pulling the protective film away from the fixed position to simultaneously separate the molding frame film 3 and the active area waste film 4 from the protective film. By setting the burr attachment method, the fixing of the molding frame film 3 and subsequent separation are achieved with a simple action.

[0044] Specifically, the second separation step includes: attaching the molded frame film 3, which has already been separated from the protective film, and the active waste film 4 to a fixed position; and using adsorption to lift the active waste film 4, thereby separating the active waste film 4 from the molded frame film 3. By setting an adsorption method to lift the active waste film 4, damage to the active waste film 4 is avoided, and the overall separation efficiency is high.

[0045] Specifically, the membrane electrode frame manufacturing method further includes a feeding step, which includes: transporting the frame composite film 1 to a designated position by rotating rollers for a cutting step; the membrane electrode frame manufacturing method further includes a transport step, which is set between the cutting step and the first separation step; the transport step includes: transporting the cut frame composite film 1 to a designated position by rotating rollers for a first separation step.

[0046] By setting a feeding step, the frame composite film 1 can be transported to the designated position by the rotation of the rollers, thereby improving the conveying efficiency of the frame composite film 1; by setting a transport step, the cut frame composite film 1 can be quickly transported to the designated position by the rotation of the rollers, which facilitates efficient connection with the subsequent first separation step, thereby improving the overall manufacturing efficiency.

[0047] like Figure 2 As shown, the present invention also provides a membrane electrode frame manufacturing apparatus, which applies the above-described membrane electrode frame manufacturing method. The membrane electrode frame manufacturing apparatus includes a cutting mechanism 10, a peeling component 30, and a separation component 40. The cutting mechanism 10 cuts the frame composite membrane 1 to obtain a shaped frame membrane 3 with a set shape, thereby separating the base waste membrane 2, the shaped frame membrane 3, and the active area waste membrane 4. The peeling component 30 cooperates with the separation component 40 to simultaneously separate the shaped frame membrane 3 and the active area waste membrane 4 from the protective membrane and transport them to the separation component 40. The separation component 40 is used to separate the shaped frame membrane 3 from the active area waste membrane 4.

[0048] The membrane electrode frame manufacturing apparatus proposed in this invention can efficiently obtain a molded frame membrane 3 of a set shape, thereby facilitating the efficient manufacturing of the molded frame.

[0049] Optionally, the cutting mechanism 10 is an automatic cutter or a die-cutting machine.

[0050] By setting the cutting mechanism 10 as an automatic cutting machine, the cutting mechanism 10 can automatically and quickly cut the border film according to the input drawing, and can quickly switch to the cutting mode to produce border films of different types and sizes, thereby effectively improving the scope of application; by setting the cutting mechanism 10 as a die cutting machine, the cost is effectively reduced.

[0051] It should be noted that in the field of proton exchange membrane fuel cells (PEMFC), the manufacturing of membrane electrode assemblies (MEAs) requires precise cutting of the membrane electrode frame to ensure the quality of the battery assembly. In a specific embodiment of the present invention, the cutting mechanism 10 can be selected from the following existing structures: 1. Laser Cutting Machine: A laser cutting machine is a high-precision cutting device suitable for cutting thin film materials. It focuses a laser beam onto the material to generate high-temperature melting or vaporization of the material, achieving non-contact cutting. The laser cutting machine can precisely control the shape and size of the cut, and is suitable for cutting the frame composite membrane 1; 2. Ultrasonic Cutting Machine: An ultrasonic cutting machine uses the energy generated by ultrasonic vibration to cut the thin film material. This cutting method is suitable for thin film materials because its cutting process does not generate heat, thereby avoiding damage to the thin film material. In addition, the ultrasonic cutting machine can also achieve high-precision cutting of the complex shape of the frame membrane in the frame composite membrane 1; 3. Precision Cutting Blade: A precision cutting blade is a common cutting tool suitable for cutting various materials. It has high controllability and precision, and can achieve complex cutting shapes; for the cutting of the frame composite film 1, a special precision cutting knife can be used for precise cutting; 4. Waterjet Cutting Machine: The waterjet cutting machine uses high-pressure water jets to cut materials. This cutting method has high cutting accuracy and flexibility and is suitable for materials of various hardness; the waterjet cutting machine does not generate heat during the cutting of the frame composite film 1, thus avoiding material damage; 5. CNC Cutting System: The CNC cutting system is an automated cutting device (i.e., an automatic cutting machine). Through input drawings, it can achieve cutting of various shapes and sizes; it has high precision and high efficiency and is suitable for mass production; the CNC cutting system can achieve complex cutting shapes and flexible cutting path settings through programming; 6. Hot Knife Cutting Machine: The hot knife cutting machine uses heated blades to cut materials. This cutting method is suitable for materials with low melting points, such as plastics and rubber; the hot knife cutting machine can achieve smooth cutting of the frame composite film 1 (i.e., smooth cutting edges without burrs); 7. Thermoforming Cutting Machine: Thermoforming cutting machine shapes and cuts materials by heating and pressure. This cutting method is suitable for flexible film materials. Thermoforming cutting machine can achieve efficient cutting of set shapes and sizes through molds; In summary, the above cutting devices can be flexibly selected according to the actual processing requirements and production scale of the frame composite film 1 to achieve efficient and accurate cutting of the frame composite film 1.

[0052] Additionally, it is worth noting that the die-cutting machine of this invention requires the use of a die and a blade during the cutting of the border film. These two tools play a crucial role in the cutting process. The specific working principle and structure of the die and blade structures in the die-cutting machine are as follows:

[0053] 1. Die-cutting structure: A die-cutting mold is used to cut the border film. It has the following characteristics: a) Die-cutting material: Dies are usually made of materials with high hardness, such as tungsten steel and alloy steel, to ensure their wear resistance and stability; b) Die-cutting shape: The shape of the die needs to be adapted to the size and shape of the border film to be cut; common die-cutting shapes include rectangular, circular, and elliptical; c) Die-cutting edge: The cutting edge on the die-cutting mold is the part that actually cuts, and it is usually designed with a sharp cutting edge to easily cut the border film; d) Die-cutting fixation: The die-cutting mold needs to be fixed on a stable platform to ensure the accuracy of the cutting process.

[0054] 2. Cutting Sheet Structure: The cutting sheet is an auxiliary tool used in conjunction with the cutting die, primarily for protecting the die and controlling the cutting process. The cutting sheet has the following characteristics: a) Material: Cutting sheets are typically made of soft and wear-resistant materials, such as soft plastic or rubber; b) Shape: The shape of the cutting sheet matches the shape of the cutting die, ensuring a tight fit; c) Thickness: The thickness of the cutting sheet needs to be moderate—neither too thin to expose the die nor too thick to affect the cutting effect; d) Installation: The cutting sheet needs to be installed on the cutting die, usually through detachable fixing methods such as slots or screws.

[0055] During the cutting of the border film, the die and the cutter cover work together to ensure the accuracy and stability of the cutting process. First, the die is mounted on a stable platform, and then the cutter cover is attached to the die. Next, the border film is placed under the die, and pressure is applied to force the die's blade to penetrate the border film, thus achieving the cut. Throughout the process, the cutter cover protects the die and controls the cutting depth.

[0056] like Figure 2 As shown, the membrane electrode frame manufacturing apparatus also includes a feeding roller assembly 20 and a receiving roller assembly 50. The feeding roller assembly 20 is used to transport the frame composite film 1 to the cutting mechanism 10 for cutting. The receiving roller assembly 50 is used to roll up and store the base waste film 2 and the protective film after they have been separated from the formed frame film 3 and the active area waste film 4. One end of the frame composite film 1 is rolled up on the feeding roller assembly 20, and the other end passes through the peeling assembly 30 and rolls up with the receiving roller assembly 50. The feeding roller assembly 20 and the receiving roller assembly 50 rotate simultaneously, driving the frame composite film 1 to move as a whole on the cutting mechanism 10 and the peeling assembly 30.

[0057] This design ensures the reliability of the overall feeding, peeling, separation, and collection processes of the membrane electrode frame manufacturing device, while also simplifying the overall structure of the device.

[0058] It should be noted that: in the first separation step, the peeling component 30 cooperates with the separation component 40 to simultaneously separate the molding border film 3 and the active area waste film 4 from the protective film and transport them to the separation component 40; in the second separation step, the separation component 40 separates the molding border film 3 from the active area waste film 4; in the storage step, the receiving roller component 50 rolls up and stores the basic waste film 2 and the protective film at the same time, and the separation component 40 stores the independently existing active area waste film 4.

[0059] like Figure 2 As shown, the peeling assembly 30 includes a first clamping and fixing structure 31, a second clamping and fixing structure 32, and a peeling platform 33. The peeling platform 33 carries the cut border composite film 1 and is movably disposed to move relative to the separation assembly 40. The second clamping and fixing structure 32 is disposed on the peeling platform 33 to follow the movement of the peeling platform 33. The first clamping and fixing structure 31 is fixedly disposed. Both the first clamping and fixing structure 31 and the second clamping and fixing structure 32 are used to fix the border composite film 1. This configuration ensures the simplification of the structure of the peeling assembly 30.

[0060] Specifically, the peeling platform 33 has an initial state and a separation state; the two ends of the portion of the frame composite film 1 on the peeling platform 33 are a fixed end 5 and a separation end 6, respectively; when the peeling platform 33 is in the initial state, the first clamping and fixing structure 31 is in the open state, and the second clamping and fixing structure 32 is in the clamping state, so as to fix the fixed end 5 of the frame composite film 1 on the peeling platform 33, and the receiving roller assembly 50 reverses so that the portion of the frame composite film 1 located between the separation end 6 and the receiving roller assembly 50 becomes longer, the longer portion is a redundant portion, and the length of the redundant portion is not less than the displacement length of the peeling platform 33 moving towards the separation assembly 40; the peeling platform 33 moves above the separation assembly 40, and drives A portion of the forming border film 3 and / or a portion of the active zone waste film 4 are bonded and fixed to a portion of the separation component 40; when the peeling platform 33 is in the separation state, the peeling platform 33 moves away from the separation component 40, driving the protective film to move, so that the forming border film 3 and the active zone waste film 4 are simultaneously separated from the protective film, and finally the forming border film 3 and the active zone waste film 4 are bonded and fixed to the separation component 40; after the forming border film 3 and the active zone waste film 4 are separated from the protective film, the first clamping and fixing structure 31 is in the clamping state, the second clamping and fixing structure 32 is in the open state, and the take-up roller assembly 50 rotates forward to drive the base waste film 2 and the protective film to be rolled up and stored at the take-up roller assembly 50.

[0061] like Figure 2 As shown, the peeling platform 33 includes a platform body 331 and a wedge 332, with the wedge 332 fixedly disposed at one end of the platform body 331 near the separation component 40. The frame composite membrane 1 slides along the surfaces of the platform body 331 and the wedge 332. The wedge 332 has a sharp corner, at which the formed frame membrane 3 and / or the active zone waste membrane 4 develop burrs, which separate from the protective membrane. The peeling platform 33 moves closer to the separation component 40, causing the burrs to adhere and be fixed to a portion of the separation component 40. The peeling platform 33 moves away from the separation component 40, causing the protective membrane to move, thereby separating the formed frame membrane 3 and the active zone waste membrane 4 from the protective membrane. By setting the wedge 332 to have a sharp corner, the burrs are efficiently and controllably controlled, ultimately allowing the formed frame membrane 3 and the active zone waste membrane 4 to adhere and be fixed to the separation component 40.

[0062] It should be noted that in one specific embodiment of the present invention, a sensor can be used to detect the flash, thereby automatically controlling the reciprocating movement of the peeling platform 33; or the specific number of rotations of the rollers can be controlled by controlling the motors in the feeding roller assembly 20 and the receiving roller assembly 50, thereby controlling the moving distance of the frame composite film 1, so that flash appears at the sharp corners of the formed frame film 3. This can be flexibly set according to actual usage requirements. For example, the motors in the feeding roller assembly 20 and the receiving roller assembly 50 can be controlled to work together so that the formed frame film 3 moves out 10mm more at the sharp corners. The part that moves out naturally curls up due to the force transmitted by the sharp corners, thereby generating flash.

[0063] like Figure 2 As shown, the membrane electrode frame manufacturing apparatus also includes a floating roller assembly 60, which is disposed between the peeling platform 33 and the cutting mechanism 10 and rolls in cooperation with the frame composite film 1. The floating roller assembly 60 can be raised and lowered, and at least a portion of the gravity is applied to the frame composite film 1 so that a portion of the frame composite film 1 is suspended. When the peeling platform 33 moves closer to the separation component 40, the distance between the peeling platform 33 and the cutting mechanism 10 increases, and the peeling platform 33 drives the suspended frame composite film 1 to move, and drives the floating roller assembly 60 to rise.

[0064] By setting the floating roller assembly 60, a portion of the frame composite film 1 is suspended. The suspended portion forms a sufficient margin between the peeling platform 33 and the cutting mechanism 10, thereby ensuring that the frame composite film 1 does not experience significant tension changes or elastic deformation when the peeling platform 33 moves closer to the separation assembly 40, thus avoiding damage to the frame composite film 1.

[0065] like Figure 2As shown, the membrane electrode frame manufacturing apparatus further includes a first pressure roller 70, a second pressure roller 80, and a first guide roller 90. The first pressure roller 70, the second pressure roller 80, and the first guide roller 90 are rotatably disposed between the peeling platform 33 and the cutting mechanism 10, respectively, with the first guide roller 90 positioned close to the peeling platform 33 and the first pressure roller 70 and the second pressure roller 80 positioned close to the cutting mechanism 10. The first pressure roller 70 and the second pressure roller 80 are positioned vertically correspondingly and roll in cooperation with the upper and lower surfaces of the frame composite film 1, respectively. The first pressure roller 70 and the second pressure roller 80 rotate in opposite directions to simultaneously flatten the frame composite film 1 after it has been cut by the cutting mechanism 10. The floating roller assembly 60 abuts against the frame composite film 1 after it has been flattened by the first pressure roller 70 and the second pressure roller 80 to apply at least a portion of the gravity to the frame composite film 1. The first guide roller 90 is used to guide the frame composite film 1, which has passed through the floating roller assembly 60, onto the peeling platform 33.

[0066] By setting the first pressure roller 70 and the second pressure roller 80, a simple structure is used to achieve efficient flatness of the frame composite film 1 after it has been cut by the cutting mechanism 10; by setting the first guide roller 90, reliable guidance of the frame composite film 1 after it has passed through the floating roller assembly 60 to the peeling platform 33 is achieved, ensuring the reliable movement of the frame composite film 1.

[0067] like Figure 2 As shown, the separation component 40 includes a robot arm 41 and a material platform 42. The robot arm 41 is movably positioned above the material platform 42. The molded frame film 3 and the active waste film 4, which are separated from the protective film, are adhered to the material platform 42. The robot arm 41 cooperates with the active waste film 4 located on the material platform 42 to drive the active waste film 4 to separate from the molded frame film 3. The robot arm 41 then moves the active waste film 4, which has been separated from the molded frame film 3, to a designated location for storage.

[0068] This design ensures the reliability of the separation component 40 while simplifying its structure.

[0069] like Figure 2 As shown, the separation component 40 also includes a waste bin 43, which is used to collect the active waste membrane 4 that has been separated from the molding frame membrane 3; the robot arm 41 includes a movable robot arm and an adsorption structure disposed on the robot arm; the adsorption structure is used to adsorb the active waste membrane 4 located on the material platform 42, and the adsorption structure releases the adsorbed active waste membrane 4 into the waste bin 43.

[0070] By setting up the waste bin 43, the waste membrane 4 of the active area separated from the molding frame membrane 3 can be reliably collected, which facilitates subsequent unified processing; by setting up the adsorption structure, damage to the waste membrane 4 of the active area is avoided, and the waste membrane 4 of the active area can be quickly and stably detached from the robot arm 41.

[0071] It should be noted that the specific waste removal method of the robotic arm 41 is as follows: the adsorption structure opens the vacuum adsorption to suck up the waste membrane 4 in the active area, and at the same time, the vacuum adsorption on the material platform 42 at the position of the waste membrane 4 in the active area is closed. The adsorption structure sucks up the waste membrane 4 in the active area and moves it above the waste bin 43 with the robotic arm. The adsorption structure closes the vacuum adsorption and at the same time opens the purging function to blow the waste membrane 4 in the active area into the waste bin 43.

[0072] In one specific embodiment of the present invention, in the second separation step, the adsorption structure adsorbs the waste membrane 4 in the active region to fix it relative to the waste membrane 4 in the active region; in the storage step, the adsorption structure blows the waste membrane 4 in the active region to separate it from the waste membrane 4 in the active region.

[0073] like Figure 2 As shown, the feeding roller assembly 20 includes a feeding drive motor, a feeding roller 21 and a second guide roller 22 that are rotatably arranged. The feeding drive motor is used to drive the feeding roller 21 to rotate. The feeding roller 21 is engaged with one end of the frame composite film 1 to drive the frame composite film 1 to move. The second guide roller 22 is engaged with the frame composite film 1 to guide the frame composite film 1 that has passed through the feeding roller 21 to the cutting mechanism 10.

[0074] like Figure 2 As shown, the membrane electrode frame manufacturing apparatus also includes a tension controller, which is electrically connected to the feed roller assembly 20 and / or the take-up roller assembly 50; the tension controller controls the operation of the feed roller assembly 20 and / or the take-up roller assembly 50 by detecting the tension of the frame composite membrane 1.

[0075] By setting a tension controller, real-time monitoring of the tension of the frame composite film 1 is achieved, as well as precise control of the operation of the feeding roller assembly 20 and / or the receiving roller assembly 50, ensuring the safe and stable operation of the film electrode frame manufacturing device and avoiding damage to the frame composite film 1.

[0076] In a specific embodiment of the present invention, tension controllers are provided at both the feeding roller assembly 20 and the receiving roller assembly 50. The tension of the entire frame composite film 1 can be adjusted by the tension controllers, with an adjustable range of 0-200N.

[0077] like Figure 2As shown, the receiving roller assembly 50 includes a receiving drive motor, a third guide roller 51 and a receiving roller 52 that are rotatably disposed. The receiving drive motor is used to drive the receiving roller 52 to rotate. The receiving roller 52 is engaged with the other end of the frame composite film 1 to drive the frame composite film 1 to move. The third guide roller 51 is engaged with the frame composite film 1 to guide the base waste film 2 and the protective film that have passed through the peeling assembly 30 to the receiving roller 52 for winding and storage.

[0078] This configuration ensures the reliability of the receiving roller assembly 50 while simplifying its structure.

[0079] like Figure 2 As shown, the receiving roller assembly 50 also includes a fourth guide roller 53, a third pressure roller 54, and a fourth pressure roller 55. The third pressure roller 54, the fourth pressure roller 55, and the fourth guide roller 53 are rotatably disposed between the third guide roller 51 and the receiving roller 52, with the fourth guide roller 53 positioned close to the receiving roller 52 and the third pressure roller 54 and the fourth pressure roller 55 positioned close to the third guide roller 51. The third pressure roller 54 and the fourth pressure roller 55 are positioned vertically correspondingly and roll in cooperation with the upper and lower surfaces of the frame composite film 1, respectively. The third pressure roller 54 and the fourth pressure roller 55 rotate in opposite directions to simultaneously flatten the base waste film 2 and the protective film that have passed through the third guide roller 51. The fourth guide roller 53 is used to guide the base waste film 2 and the protective film that have been flattened by the third pressure roller 54 and the fourth pressure roller 55 to the receiving roller 52.

[0080] By setting the third pressure roller 54 and the fourth pressure roller 55 to work together, reliable flatness of the base waste film 2 and the protective film is achieved, which facilitates subsequent rolling and storage; by setting the fourth guide roller 53, the base waste film 2 and the protective film are guided to the take-up roller 52.

[0081] In a specific embodiment of the present invention, the first pressure roller 70 and the fourth pressure roller 55 are actively rotating rubber rollers, which are driven by motors to move the frame composite film 1.

[0082] Thus, the membrane electrode frame manufacturing device proposed in this invention uses a low initial tack frame film and cuts the frame film into a specific shape through a semi-cutting method (completely cutting the frame film while leaving the protective film intact). That is, the cutting depth is greater than the thickness of the frame film but less than the total thickness of the frame film and the protective film, thereby achieving automatic forming of the frame film. At the same time, the robot arm 41 separates the formed frame film 3 from the waste film 4 in the active area. By using the feeding roller assembly 20, the peeling assembly 30, the separation assembly 40, and the receiving roller assembly 50, this invention achieves automated and efficient production of the frame film in a production line, resulting in high production efficiency and better meeting capacity requirements.

[0083] like Figure 3As shown, the forming process of the membrane electrode frame is as follows: Figure 3 As shown, the frame composite film 1 is cut to form a basic waste film 2, a shaped frame film 3, and an active zone waste film 4. After being peeled off by the peeling component 30 in the first separation step, the shaped frame film 3 and the active zone waste film 4 are placed on the material platform 42. The active zone waste film 4 is picked up by the robot arm 41 and placed in the waste bin 43. The basic waste film 2 and the protective film are rolled up and stored by the receiving roller assembly 50.

[0084] In summary, this invention provides a method and apparatus for manufacturing membrane electrode frames. By incorporating a cutting step, this invention efficiently separates the base waste membrane 2, the formed frame membrane 3, and the active area waste membrane 4, ensuring the formed frame membrane 3 has a predetermined shape. Furthermore, it allows the base waste membrane 2, the formed frame membrane 3, and the active area waste membrane 4 to be bonded and fixed to the protective film, enabling them to move together with the protective film. In this case, the protective film functions as an additional support film in existing technologies. Therefore, this invention, through a redesigned cutting method, eliminates the need for support films and other auxiliary materials, thus saving on subsequent processing steps for these materials. The processing technology effectively simplifies the manufacturing process of the border film and saves on required equipment, thereby improving the production efficiency of the border film. By setting a first separation step, a second separation step, and a storage step, both automatic forming of the border film and reliable recycling of waste materials are achieved. The method of this invention is significantly different from the existing technology in terms of the cutting and forming method of the border composite film 1, the separation method of the border film, and the waste discharge method. Moreover, the method and required device of this invention are simpler, easier and more efficient to implement, and suitable for large-scale promotion and use. In the subsequent cutting step, an existing automatic cutting machine can be used to quickly change the border film of different sizes and shapes according to different drawings, better meeting the diverse production needs of the border film.
