Description

Technical Field

[0001] The present invention relates to the technical field of fuel cells, and in particular to a method, device and equipment for laminating and aligning membranes of membrane electrode frames. Background Art

[0002] A fuel cell is a power generation device that converts the chemical energy in a fuel into electrical energy through a chemical reaction. It has the advantages of high power density, high conversion rate, and low environmental pollution. The conversion efficiency of a hydrogen fuel cell can easily reach more than 60%, and the product after the reaction is pollution-free water. Therefore, it was once considered to be one of the important development directions of new energy vehicles in the future. The membrane electrode assembly (MEA) is the key core component of a hydrogen fuel cell and is the site of the electrochemical reaction of a hydrogen fuel cell.

[0003] The membrane electrode is composed of a proton exchange membrane, anode and cathode catalyst layers, cathode and cathode gas diffusion layers, and frame membranes supported on both sides. The frame membrane components are mainly single-layer, double-layer, and multi-layer frames (generally four layers) according to design requirements. There are two main types of existing membrane electrode two-layer and multi-layer frame membrane bonding: one is to use proton membrane as a roll to obtain a fuel cell chip (catalyst coated membrane, CCM) and then bond the frame membrane on both sides; the other is to prepare the frame and CCM into sheets and then bond them layer by layer. Among them, the cost of the bonding equipment for roll materials is high and the technical requirements are high, and it is generally used for batch preparation; while the membrane electrode preparation of sheets is suitable for efficient research and development and small-batch production and manufacturing of enterprises, and has always attracted much attention.

[0004] When the frame film of the membrane electrode multilayer sheet is laminated, due to the frame film size deviation and equipment lamination error, the frame film will be misaligned after the two layers are laminated. Therefore, when laminating the multilayer frame film, since there will be errors every time laminating, the misalignment of the finished frame film will increase with the misalignment of the semi-finished product and the increase in the number of laminating times, which will greatly reduce the alignment accuracy of the product frame, and seriously lead to unqualified products.

[0047] Figure 3 It is a schematic diagram of the structure of an electronic device provided by an embodiment of the present invention. DETAILED DESCRIPTION

[0048] In order to make the purpose, technical solution and advantages of the present invention clearer, the technical solution of the present invention will be clearly and completely described below in conjunction with the drawings of the present invention. Obviously, the described embodiments are part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0049] Combine the following Figure 1-Figure 3 The invention describes a membrane electrode frame membrane lamination alignment method, device and equipment.

[0050] Figure 1 It is a schematic diagram of the process of the membrane electrode frame film lamination and alignment method provided in an embodiment of the present invention.

[0051] like Figure 1 As shown, the present embodiment provides a method for laminating and aligning a membrane electrode frame film, wherein the membrane electrode frame film comprises a bottom frame film and at least one upper frame film, wherein at least one group of bottom positioning holes is provided on the bottom frame film, and at least one group of upper positioning holes is provided on each upper frame film, wherein the orthographic projection of each group of bottom positioning holes is within the orthographic projection boundary of the upper positioning holes, and the laminating and aligning method mainly comprises the following steps:

[0052] 101. Position the bottom frame film and identify the bottom positioning holes on the bottom frame film.

[0053] In a specific implementation process, when the multi-layer frame film is bonded, in order to ensure the bonding accuracy, the structure of each layer of the frame film is first improved. The main method is to set positioning holes on each layer of the frame film. For example, a bottom layer positioning hole is set on the bottom layer frame film, and an upper layer positioning hole is set on each upper layer frame film. The bottom layer positioning hole and the upper layer positioning hole can be set diagonally, wherein the role of the bottom layer positioning hole is to provide a positioning reference when the upper layer frame film is bonded, and the role of the upper layer positioning hole is to be able to pass through the upper layer positioning hole to locate the bottom layer positioning hole when bonding. The upper layer positioning hole and the bottom layer positioning hole are concentrically arranged, and the bottom layer positioning hole and the upper layer positioning hole are circular or polygonal. For example, if it is circular, the upper layer positioning hole and the bottom layer positioning hole are concentric circles. The main function of the concentric arrangement is that the upper layer positioning hole will not block the bottom layer positioning hole, ensuring that each time the upper layer frame film is bonded, the complete bottom layer positioning hole can be located, thereby ensuring that the bottom layer positioning hole is used as the bonding reference.

[0054] The process of laminating the frame film is to laminar the frame films layer by layer. Therefore, it is necessary to accurately locate the bottom frame film and accurately identify the bottom positioning holes. Only by ensuring the accurate positioning of the bottom positioning holes can the accurate lamination of each subsequent upper frame film be better guaranteed.

[0055] The orthographic projection of each group of bottom-layer positioning holes is within the orthographic projection boundary of the upper-layer positioning holes, which means that the area of ​​the bottom-layer positioning holes is smaller than the area of ​​the upper-layer positioning holes, the orthographic projection of the bottom-layer positioning holes is part of the orthographic projection of the upper-layer positioning holes, and the orthographic projection of the upper-layer positioning holes includes the orthographic projection of the bottom-layer positioning holes.

[0056] 102. Using the bottom layer positioning holes as a laminating reference, laminating each upper layer frame film in turn.

[0057] After identifying the bottom layer positioning holes, the target path is automatically generated, and automatic bonding is performed through the adsorption platform. The upper frame film is bonded to the bottom frame film in turn, and each time bonding is performed, the bottom layer positioning holes are used as the bonding reference. Therefore, even if there is a deviation during bonding, there is still only one error when multiple frame film bondings are performed, thereby effectively reducing the impact of bonding errors on product quality and effectively improving the product qualification rate.

[0058] By setting corresponding positioning holes at the same positions of different layers of frame films, and the upper positioning holes will not block the bottom positioning holes, thereby not affecting the grasping of the bottom positioning holes, and the bottom positioning holes are set on the bottom frame film of the lowest layer, so that in the process of multiple bonding, the frame film semi-finished products can use the bottom positioning holes as the visual positioning reference, so that it can be ensured that in the multi-layer bonding process, the final bonding accuracy of the product is the same as the bonding accuracy of the two layers of film, fundamentally avoiding the impact of product misalignment during the bonding process on subsequent bonding.

[0059] Furthermore, on the basis of the above-mentioned embodiments, the present embodiment uses the bottom layer positioning holes as the bonding reference respectively, and sequentially bonds each upper layer frame film, including: sequentially locating the positional relationship between the bottom layer positioning holes and the current upper layer positioning holes; based on the positional relationship, determining the deviation between the current upper layer positioning holes and the bottom layer positioning holes; determining the compensation value corresponding to the deviation, and bonding the upper layer frame film corresponding to the current upper layer positioning holes with the bottom layer frame film based on the compensation value.

[0060] Specifically, when laminating the upper frame film, it is necessary to accurately locate the positional relationship between the bottom layer positioning hole and the upper layer positioning hole each time, and then determine the deviation based on the positional relationship, and determine the compensation value to eliminate the deviation through calculation processing, so that the compensation value is added to the planning of the laminating path during the laminating process, and the target path is determined more accurately to complete a more precise laminating. It is also possible to adjust the position of the upper frame film according to the compensation value after moving the upper frame film above the bottom frame film to ensure the accuracy of the laminating of the upper frame film and the bottom frame film. By compensating for the deviation, the error in the laminating process can be minimized, and the qualified rate of the product is higher.

[0061] Further, on the basis of the above embodiments, there are three upper frame films in this embodiment, namely, a first upper frame film, a second upper frame film and a third upper frame film, and each upper frame film is laminated in turn with the bottom positioning hole as the laminating reference, including: locating the bottom positioning hole through a visual positioning system; laminating the first upper frame film on the bottom frame film with the bottom positioning hole as the laminating reference; collecting the bottom positioning hole through the upper positioning hole corresponding to the first upper frame film through the visual positioning system; laminating the second upper frame film on the first upper frame film with the bottom positioning hole as the laminating reference; collecting the bottom positioning hole through the upper positioning hole corresponding to the first upper frame film and the upper positioning hole corresponding to the second upper frame film through the visual positioning system; laminating the third upper frame film on the second upper frame film with the bottom positioning hole as the laminating reference.

[0062] Specifically, for example, when four layers of frame film are bonded together, a group of bottom layer positioning holes are set at the diagonal of the bottom layer frame film. Taking a circle as an example, the size of the bottom layer positioning holes can be set to a diameter of Φ6mm, while the first upper layer frame film is Φ8mm, and the second upper layer frame film and the third upper layer frame film can be set to Φ8mm (or above Φ8mm). During the first bonding, the first upper layer frame film is bonded to the bottom layer frame film, and Φ6mm is used as the visual positioning bonding reference. During the second bonding, the two-layer frame film bonding semi-finished product is bonded to the second upper layer frame film using the Φ6mm hole as the visual positioning bonding reference. For the third bonding, the three-layer frame film bonding semi-finished product is bonded to the third upper layer frame film using the Φ6mm hole as the visual positioning bonding reference, thereby ensuring that product misalignment during the bonding process has no effect on subsequent bonding, and each bonding uses the bottom layer positioning hole Φ6mm as the bonding positioning reference.

[0063] Before laminating the second upper frame film onto the first upper frame film using the bottom positioning hole as the laminating reference, the method further includes: positioning the fuel cell chip; laminating the fuel cell chip onto the first upper frame film using the bottom positioning hole as the laminating reference.

[0064] Specifically, the fuel cell chip (catalyst coated membrane, CCM) is a catalyst / proton exchange membrane assembly prepared by coating the fuel cell catalyst on both sides of the proton exchange membrane. That is, the CCM is attached between the first upper frame membrane and the second upper frame membrane, and the bottom positioning holes are also used for positioning during the lamination and positioning, and the lamination movement trajectory can be moved according to the route based on the positioning holes of the bottom layer.

[0065] While laminating the second upper frame film onto the first upper frame film with the bottom layer positioning hole as the laminating reference, the upper layer positioning hole corresponding to the second upper frame film is located; the position deviation between the upper layer positioning hole corresponding to the second upper frame film and the bottom layer positioning hole is determined; based on the position deviation, the second upper frame film is laminating onto the fuel cell chip with the bottom layer positioning hole as the reference.

[0066] Among them, each upper frame film is laminated in turn, including: respectively adsorbing the bottom frame film and the upper frame film through different adsorption platforms; respectively controlling the movement of different adsorption platforms to adjust the corresponding positions of the bottom frame film and the upper frame film, and laminating the upper frame film on the bottom frame film in turn.

[0067] Specifically, the detailed process of laminating each upper frame film in turn is as follows:

[0068] Place the bottom frame film on the first adsorption platform with a visual positioning system and turn on the vacuum, peel off the release film, then place the CCM sheet on the second adsorption platform with a visual positioning system and turn on the vacuum, then place the first upper frame film on the third adsorption platform with a visual positioning system and turn on the vacuum, and peel off the release film.

[0069] Based on the bottom positioning holes on the bottom frame film, the bottom frame film of the first adsorption platform and the first upper frame film of the second adsorption platform are photographed and positioned, and then the compensation deviation is determined, and the first adsorption platform is controlled to flip based on the compensation deviation, and the second adsorption platform is controlled to translate to the bottom of the first adsorption platform, and the first upper frame film is buckled on the bottom frame film on the first adsorption platform, and then the second adsorption platform is removed, and the first adsorption platform is flipped back to its original position, maintaining the vacuum, and at the same time, the release film of the first upper frame film is peeled off.

[0070] Based on the bottom positioning holes on the bottom frame film, the bottom frame film of the first adsorption platform and the CCM of the third adsorption platform are photographed and positioned, and the compensation deviation is determined. Then, the movement is performed based on the bottom positioning holes. First, the first adsorption platform is controlled to flip, and the third adsorption platform is translated to the bottom of the first adsorption platform. The third adsorption platform is controlled to drive the rolling device to contact the first adsorption platform and move forward evenly. After the rolling is completed, the third adsorption platform is removed, and the first adsorption platform is controlled to flip to maintain vacuum, thereby completing the bonding of the CCM and the first upper frame film.

[0071] Keep the semi-finished product of the first upper frame film and CCM attached to it unchanged, vacuum the first adsorption platform, and remove the frame bottom film of the semi-finished product of the first adsorption platform. Place the second upper frame film on the third adsorption platform with a visual positioning system and turn on the vacuum to peel off the release film. Perform the same bonding steps as the first upper frame film to complete the bonding of the second upper frame film. Similarly, the bonding of the third upper frame film can be completed. Finally, the bonding of the four layers of frame film is completed, and the vacuum of the first adsorption platform is turned off to take out the finished product.

[0072] It should be emphasized that when visually positioning the bottom frame film, the first upper frame film, the second upper frame film and the third upper frame film, the corresponding positioning holes are used, and when bonding different frame films, the bottom positioning holes of the bottom frame film are used as the bonding reference to generate the target trajectory, thereby ensuring that despite multiple bondings, there will be no accumulation of bonding errors, ensuring that the bonding accuracy can better meet product quality requirements.

[0073] Further, based on the above embodiment, the present embodiment determines the lamination accuracy of the membrane electrode frame membrane; the lamination accuracy is increased by a preset multiple of the size of the bottom positioning hole to serve as the size of the upper positioning hole.

[0074] Specifically, in order to better ensure the fitting accuracy, it is necessary to determine the size of the bottom layer positioning hole and the upper layer positioning hole. The orthographic projection of the upper layer positioning hole needs to cover the orthographic projection of the bottom layer positioning hole, and the specific coverage needs to be determined according to the fitting accuracy. The bottom layer positioning hole and the upper layer positioning hole determined according to the fitting accuracy can better ensure that when the upper layer positioning hole is fitted, the complete bottom layer positioning hole can be detected each time, and the fitting is performed with the complete bottom layer positioning hole as the fitting reference. Therefore, since the upper layer positioning hole will not block the bottom layer positioning hole each time, the fitting accuracy after multiple fittings can be better guaranteed, and the product quality can be better guaranteed. For example, if the diameter of the bottom layer positioning hole is Φ6mm and the fitting accuracy is 2mm, the diameter of the upper layer positioning hole is Φ8mm or above, wherein the sizes of all the upper layer positioning holes can be the same or different, but they need to be greater than or equal to Φ8mm to ensure that the detection and positioning of the bottom layer positioning hole will not be caused. At the same time, even if an error occurs within the fitting accuracy, the upper layer positioning hole will not block the bottom layer positioning hole.

[0075] By setting positioning holes with stepped apertures at the same position of different frame films, that is, the bottom layer positioning holes are different in size from the upper layer positioning holes, and the bottom layer positioning holes are the smallest in orthographic projection and are set on the bottom layer frame film. The upper layer positioning holes will not block the bottom layer positioning holes during each single lamination, and the semi-finished products obtained after multiple laminations also use the smallest bottom layer positioning holes as the positioning and lamination reference. This ensures that the final lamination accuracy of the product is the same as that of the two-layer frame film, fundamentally avoiding the impact of the misalignment of the semi-finished products on the subsequent lamination during the lamination of multiple frame films, and effectively improving product quality.

[0076] Based on the same general inventive concept, the present invention also protects a membrane electrode frame film fitting and alignment device. The membrane electrode frame film fitting and alignment device provided by the present invention is described below. The membrane electrode frame film fitting and alignment device described below and the membrane electrode frame film fitting and alignment method described above can be referenced to each other.
