TECHNICAL FIELD
[0001] The present application belongs to the technical field of fuel cell manufacturing, and particularly relates to a fuel cell membrane electrode seven-in-one production product conveying line. BACKGROUND
[0002] In the field of fuel cell manufacturing, particularly in the production process of membrane electrode assemblies (MEAs), there are multiple components such as anode gas diffusion layers (GDLs), cathode GDLs, and five-in-one lamination semi-finished products, etc. that need to be precisely combined. Traditional production processes usually rely on manual or semi-automated equipment for the assembly of these components, which leads to several key problems:
[0003] Due to the lack of smooth connection between each process step, especially the large amount of manual handling and adjustment during the process from individual parts to components and then to finished products, the overall efficiency and capacity of the production line are greatly limited. The conversion time between each process on the traditional production line is long, including the loading, unloading and intermediate handling process of the product, which prolongs the entire production cycle and cannot meet the ability to quickly respond to market demand. For different specifications of products or newly introduced process flows, existing production equipment often needs to be reconfigured and debugged complexly, which not only consumes time but also increases the uncertainty of production. The traditional production line layout is relatively fixed, and it is difficult to flexibly add or remove specific process units according to actual needs, which is not conducive to the enterprise to quickly adapt to market changes and technological progress. Many existing production lines still need a large amount of manual participation to complete operations such as positioning, lamination, etc., which not only reduces work efficiency, but also may cause unstable product quality due to human factors.

[0030] EMBODIMENT
[0031] Please refer to Figures 1-7 The present application is a fuel cell membrane electrode seven-in-one production product transportation line, which comprises a front elevator 1, a plurality of function single machines 2 and a rear elevator 3. The front elevator 1, the function single machines 2 and the rear elevator 3 are all fixed horizontally on the working ground. The front elevator 1 and the rear elevator 3 are respectively arranged at the starting end and the end of the whole production line, and are used for the up-down circulation of the mover carrier 10. The front elevator 1 and the rear elevator 3 each comprise a lifting module 4 and a connection linear motor 5. The lifting module 4 and the connection linear motor 5 cooperate with each other to realize the up-down movement and inflow-outflow function of the mover carrier 10. The plurality of function single machines 2 are arranged in sequence and spliced into a production line. The function single machine 2 is provided with an upper linear motor 6 and a lower belt line 7. The upper linear motor 6 is located on the equipment workbench, and the lower belt line 7 is located on the lower layer of the equipment. The two are in one-to-one docking to form a complete upper and lower two-layer structure.
[0032] Specifically, the mover carrier 10 has a porous adsorption platform 12, and is connected with an external negative pressure adsorption unit 8 through a one-way air joint 13. The mover carrier 10 is also equipped with a mechanical valve 14 connected with a negative pressure release unit 9, which is used to control the negative pressure state in the porous adsorption platform 12, so as to release the product.
[0033] Further, the upper linear motor 6 is composed of a plurality of independent linear motor coil parts, and each linear motor coil part cooperates with the linear motor mover 11 on the corresponding function single machine 2. The lower belt line 7 is composed of a plurality of independent belts, which serve as the circulation channel of the mover carrier 10.
[0034] In addition, each functional unit 2 is equipped with an electronic tag 15 for recording and tracking the state information of the mover carrier 10 and the processing progress of the product carried thereby. The front elevator 1 and the rear elevator 3 are provided with sensors for detecting the position of the mover carrier 10 and adjusting the lifting speed accordingly to ensure smooth transition of the mover carrier 10 to the corresponding conveying line. The functional units 2 are seamlessly connected by the connecting linear motor 5 for continuous movement of the mover carrier 10 on the entire production line.
[0035] The application provides a fuel cell membrane electrode seven-in-one production product conveying line, which comprises a front elevator 1, a plurality of functional units 2 and a rear elevator 3, and all components are fixed horizontally on the working ground. The front elevator 1 and the rear elevator 3 are respectively arranged at the starting end and the end of the entire production line to realize the backflow circulation of the mover carrier 10 between the upper and lower layers. Each elevator comprises a lifting module 4 and a connecting linear motor 5, which work cooperatively to complete the vertical lifting and horizontal conveying functions of the mover carrier 10. The plurality of functional units 2 are arranged in sequence along the production line and are closely connected. Each functional unit 2 is provided with an upper linear motor 6 and a lower belt line 7. The upper linear motor 6 is arranged on the equipment workbench and serves as the main conveying channel. The lower belt line 7 is located at the lower part of the equipment and serves as the backflow path of the mover carrier 10. The two are connected at both ends of the functional unit 2 to form a complete double-layer closed-loop conveying system. The mover carrier 10 carries the fuel cell membrane electrode assembly to be processed and is provided with a linear motor mover 11 at the bottom, which can cooperate with the upper linear motor 6 of each functional unit 2 to realize high-precision and high-speed non-contact driving. The mover carrier 10 is also provided with a porous adsorption platform 12 for adsorption and fixation, which is connected with an external negative pressure adsorption unit 8 through a one-way gas joint 13 to keep the product stable during operation. At the same time, the mover carrier 10 is provided with a mechanical valve 14 connected with a negative pressure release unit 9 for releasing the adsorption state to facilitate the release and transfer of the product. The entire conveying line adopts modular design, and the functional units 2 are seamlessly connected by the connecting linear motor 5 to ensure the continuous movement of the mover carrier 10 between stations and avoid pauses or misplacement caused by switching. In addition, the front elevator 1 and the rear elevator 3 are provided with sensors inside to detect the position of the mover carrier 10 in real time and dynamically adjust the lifting speed to ensure smooth transition of the mover carrier 10 to the corresponding conveying line. The electronic tag 15 is also arranged in each functional unit 2 to record the state information of the mover carrier 10 and the processing progress of the product carried thereby, realizing the whole-process tracking and control of the production process. Through the above structural design, the conveying line realizes efficient, precise and automated transmission of the fuel cell membrane electrode assembly in seven main processes, and is suitable for flexible production requirements of multiple varieties and small batches.
[0036] The specific use steps of the present application are as follows: first, the front elevator 1 transports the mover carrier 10 without loading any product to the starting position of the upper linear motor 6 line body, that is, the first functional single machine 2 loading and unloading position. At this time, the front elevator 1 completes the up and down movement of the mover carrier 10 and the inflow and outflow function through the internal lifting module 4 and the connection linear motor 5. Then, the first functional device starts to operate, and after accurate positioning, the anode GDL is placed on the mover carrier 10. Subsequently, the external negative pressure adsorption unit 8 is connected with the one-way air connector 13 on the mover carrier 10, and the negative pressure adsorption is carried out on the porous adsorption platform 12, so as to ensure that the product is stably fixed on the mover carrier 10 and a closed negative pressure cavity is formed.
[0037] When the product parts and the mover carrier 10 with the formed closed negative pressure cavity move along the upper linear motor 6 to the loading and unloading position of the next functional device, the next step operation is carried out. When the mover carrier 10 reaches the next functional single machine 2, the negative pressure release unit 9 of the station will break the vacuum as needed, or directly continue to adhere other components such as the six-in-one semi-finished product of the five-in-one adhesion and the seven-in-one finished product of the six-in-one and the cathode GDL adhesion. After each process is completed, the corresponding negative pressure adsorption or release unit will be repeatedly operated to ensure the safe transfer of the product.
[0038] This process will be repeated among multiple functional single machines 2 until the fuel cell membrane electrode assembly is completely assembled into a seven-in-one finished product. The finished product flows to the visual inspection station and the air tightness detection station for quality inspection. Finally, the mover carrier 10 with the finished product moves to the unloader position at the end of the production line, and the negative pressure release unit 9 works again to break the vacuum and take down the finished product. The empty mover carrier 10 is transported by the rear elevator 3 to the lower belt return line, and then returns to the front elevator 1 through the bottom return line, preparing for a new round of product transportation process. The whole system realizes the recycling of the mover carrier 10 through the design of the front elevator 1, the rear elevator 3 and the bottom return line, ensuring the continuity and efficiency of the production.
