Description

Technical Field

[0001] The present invention relates to the technical field of fuel cells, and in particular to a packaging method and packaging equipment for a cold film electrode frame. Background Art

[0002] The membrane electrode is the core component of the fuel cell, including the frame membrane, gas diffusion layer and three-layer membrane structure, where the three-layer membrane structure is a proton exchange membrane and an anode catalyst layer and a cathode catalyst layer respectively transferred on both sides of the proton exchange membrane by coating. The development technology of the membrane electrode includes pulping, coating, transfer, frame packaging and gas diffusion layer packaging. The frame packaging includes hot pressing packaging and cold pasting packaging. Cold pasting packaging uses pressure-sensitive adhesive frame membrane materials to directly encapsulate the frame membrane by controlling the bonding pressure and bonding speed.

[0003] The existing cold-stick packaging steps include: a punching machine punches a large piece of frame film to obtain a small piece of frame film with a hollowed-out reaction area, and a membrane electrode requires two symmetrical anode and cathode frame films; the punching machine punches the rolled three-layer membrane structure into a size larger than the frame reaction area; the three-layer membrane structure, the cathode frame film and the anode frame film are placed on the left, middle and right platforms of the bonding equipment respectively; the middle platform is turned over to make the cathode frame with glue face downward, the left platform is driven to move to the bottom of the middle platform and raised, so that the three-layer membrane structure is bonded to the cathode frame reaction area and then reset; the position of the three-layer membrane structure is adjusted, and the middle platform is turned over, and the right platform is driven to move to the bottom of the middle platform and raised, so that the anode frame is rolled from left to right and bonded to the cathode frame of the middle platform to achieve the purpose of packaging; the punching equipment punches water vapor holes on the packaged membrane electrode.

[0004] During the cold-sticking packaging process, wrinkles will appear when the three-layer membrane structure is lifted and bonded to the frame film. If the wrinkles are severe, it will lead to incomplete sealing and air leakage. Or, during the rolling and bonding process of the anode and cathode frames, the reaction zone area is squeezed and reduced due to uneven force, which affects the performance of the membrane electrode and increases the difficulty of encapsulating the gas diffusion layer.

[0044] Embodiment 1

[0045] In the existing cold-sticking packaging process, during the lifting and bonding process between the three-layer membrane structure 100 and the frame film 200, wrinkles will appear when the three-layer membrane structure 100 is bonded to the frame film 200. If the wrinkles are severe, it will lead to incomplete sealing and leakage. Alternatively, during the rolling and bonding process of the anode and cathode frames, the reaction zone area is squeezed and reduced due to uneven force, which affects the performance of the membrane electrode and increases the difficulty of packaging the gas diffusion layer.

[0046] In view of this, the packaging method of the cold-stick film electrode frame provided by the embodiment of the present invention includes cutting to obtain a frame film 200 with a hollowed-out reaction area; fixing the frame film 200 on the first vacuum adsorption platform 300 according to the position of the first positioning mechanism, and using the filling layer 210 to fill the reaction area of ​​the frame film 200; fixing the cut three-layer film structure 100 on the second vacuum adsorption platform, removing the protective film of the frame film 200 on the first vacuum adsorption platform 300, and after the first positioning mechanism is aligned, the first vacuum adsorption platform 300 is flipped over, and the second vacuum adsorption platform is moved to the bottom of the first vacuum adsorption platform 300 and lifted or rolled. The packaging method of the cold-bonded film electrode frame uses a first vacuum adsorption platform 300 to fix the frame film 200, and fills a filling layer 210 at a position corresponding to the reaction area of ​​the frame film 200 on the first vacuum adsorption platform 300, so as to eliminate the height difference between the frame film 200 and the three-layer membrane structure 100 during the bonding process, so that the three-layer membrane structure 100 is flat and wrinkle-free during and after the bonding process, and the frame film 200 is evenly stressed during the bonding process. The reaction area will not be deformed after the frame is bonded, thereby reducing the risk of membrane electrode leakage, ensuring the area of ​​the membrane electrode reaction area, and making the performance of the membrane electrode more stable.

[0047] In the optional scheme of the embodiment of the present invention, the frame film 200 with two hollowed-out reaction areas is cut; one of the cut frame films 200 is fixed on the first vacuum adsorption platform 300 according to the position of the first positioning mechanism, and the reaction area of ​​the frame film 200 is filled with a filling layer 210; the cut three-layer membrane structure 100 is fixed on the second vacuum adsorption platform, and the protective film of the frame film 200 on the first vacuum adsorption platform 300 is removed. After the first positioning mechanism is aligned, the first driving mechanism drives the first vacuum adsorption platform 300 to flip, and the second driving mechanism drives the second vacuum adsorption platform to move to the bottom of the first vacuum adsorption platform 300 and lift or roll; the second vacuum adsorption platform and the first vacuum adsorption platform 300 are reset, and the protective film of the three-layer membrane structure 100 is removed; the first vacuum adsorption platform 300 is flipped, and the position of the other cut frame film 200 installed with the third positioning mechanism is fixed on the third vacuum adsorption platform, and the protective film is removed, and the third driving mechanism drives the third vacuum adsorption platform to move to the bottom of the first vacuum adsorption platform 300 and lift or roll.

[0048] Specifically, the filling layer 210 is adhered to the first vacuum adsorption platform 300 .

[0049] The filling layer 210 is filled on the first vacuum adsorption platform 300 to ensure that the surface of the three-layer film structure 100 is flat and the reaction area of ​​the frame film 200 remains unchanged.

[0050] In an optional solution of the embodiment of the present invention, two frame films 200 are cut, and the cut frame film 200 at the reaction area is retained; one of the cut frame films 200 is fixed on the first vacuum adsorption platform 300 according to the position of the first positioning mechanism, and the cut frame film 200 reaction area residue is used to remove the protective film as the filling layer 210 to fill the reaction area of ​​the frame film 200.
