Description

Technical Field

[0001] The present invention relates to the technical field of fuel cells, and in particular to a membrane electrode material detection system. Background Art

[0002] At present, the main application scenarios of fuel cells are buses, passenger vehicles, freight vehicles and other scenarios, which require a large power to drive the equipment. Therefore, in order to achieve the above requirements, the fuel cell stack will assemble multiple bipolar plates and membrane electrodes (MEA) by nesting each other to form a single battery in series to form a fuel cell stack. According to the basic principles of physical circuits, if a battery fails in series, the entire circuit will fail; therefore, the requirements for MEA incoming materials are high, and it is necessary to ensure that each piece of MEA is qualified material. At the same time, the MEA raw material production workshop and the stack assembly production workshop are usually not in the same area, and damage will occur during transportation, which needs to be removed in time.

[0003] However, the existing incoming material inspection method is mainly semi-automatic manual inspection, which is carried out through manual visual inspection and manual placement on the airtight detection unit equipment for airtight testing; in this process, manual inspection requires multiple contacts with the membrane electrode, which can easily cause the carbon paper on the MEA material to fall off and secondary contamination; and due to its material characteristics, MEA materials are prone to static electricity and adhesion, especially when multiple pieces of MEA materials are stacked, the next piece of material is easily adsorbed by the suction cup of the previous MEA, causing the material position to shift, affecting subsequent inspection and assembly operations.

[0044] It should be noted that, in the absence of conflict, the embodiments and features in the embodiments of the present application can be combined with each other. The present invention will be described in detail below with reference to the accompanying drawings and in combination with the embodiments.

[0045] In order to solve the problem of low efficiency in the prior art of using a semi-automatic manual detection method to perform qualified detection on incoming membrane electrode materials, the present invention provides a membrane electrode raw material detection system.

[0046] Please refer to Figures 1 to 10 As shown, the technical solution of the present invention provides a membrane electrode raw material detection system, including a detection device and a feeding device 40; the detection device includes a first detection device 10, a second detection device 20 and a third detection device 30 arranged in sequence along a preset process flow direction; the feeding device 40 is arranged on one side of the detection device, so as to transfer the raw material 1 to be tested between the first detection device 10, the second detection device 20 and the third detection device 30; wherein the first detection device 10 is used to detect the outer surface of the raw material 1 to be tested, and determine whether the raw material 1 to be tested is qualified; the second detection device 20 is used to detect the thickness of the raw material 1 to be tested; the third detection device 30 has a sealed space for accommodating the raw material 1 to be tested, so as to perform an airtight detection on the raw material 1 to be tested located in the sealed space.

[0047] By applying the technical solution of this embodiment, the appearance, thickness and air tightness of the membrane electrode raw material are automatically detected through the integrated first detection device 10, the second detection device 20 and the third detection device 30. Compared with manual detection, the detection efficiency and accuracy are significantly improved, and the error and pollution risks caused by human operation are reduced, thereby solving the problem of low efficiency of qualified detection of membrane electrode incoming materials using semi-automatic manual detection methods in the prior art. At the same time, this comprehensive detection ensures that the quality of the raw materials meets the standards before entering the fuel cell stack production, thereby improving the performance and reliability of the final product. And through the coordinated work of the feeding device 40 and the detection equipment, the raw material 1 to be tested can be seamlessly transferred between different detection devices, realizing a continuous production process, avoiding interruption of the production line, ensuring production efficiency and stable operation of the production line, and by removing unqualified raw materials at an early stage, reducing the rework cost caused by raw material quality problems in the later stage of production, and improving the overall production economic benefits.

[0048] In this embodiment, the raw material 1 to be tested is a fuel cell stack MEA raw material.

[0049] like Figure 2 As shown, the first detection device 10 includes a first support frame 11, a detection platform 12 and a camera component 13; the detection platform 12 is movably arranged on the first support frame 11 along the first direction, and the raw material 1 to be tested is used to be placed on the detection platform 12; the camera component 13 is movably arranged on the first support frame 11 along the second direction, so that when the detection platform 12 drives the raw material 1 to be tested to move to a position close to the camera component 13, the camera component 13 reciprocates along the second direction to detect the outer surface of the raw material 1 to be tested; wherein the first direction and the second direction are arranged perpendicular to each other. In this way, by controlling the detection platform 12 to drive the raw material 1 to be tested located thereon to move along the first direction to the bottom of the camera component 13, it is ensured that the camera component 13 is aligned with the raw material 1 to be tested at the best position and angle and reciprocates along the second direction, so as to perform a more accurate appearance scan of the raw material 1 to be tested, and the data is synchronously uploaded to the controller seat for data analysis, which reduces the overall detection time and improves the detection efficiency of the equipment. At the same time, the vertical setting of the first direction and the second direction enables the operator to flexibly adjust the detection platform 12 and the camera component 13, allowing the camera component 13 to perform an all-round scan on the surface of the raw material 1 to be detected, thereby improving the comprehensiveness and efficiency of the detection.

[0050] Specifically, the raw material 1 to be tested has a first detection surface and a second detection surface that are arranged oppositely, and the first detection device 10 also includes a first placement plate 120 and a second placement plate 121; the first placement plate 120 is rotatably arranged on the detection platform 12, and the second placement plate 121 is arranged on the detection platform 12 at intervals from the first placement plate 120; wherein, when the raw material 1 to be tested is located on the first placement plate 120, the first detection surface is arranged toward the camera component 13; when the raw material 1 to be tested is located on the second placement plate 121, the second detection surface is arranged toward the camera component 13. In this way, by providing a rotatable first placement plate 120 and a fixedly spaced second placement plate 121, efficient double-sided detection of the membrane electrode raw material can be achieved, which can ensure that the collected detection data is more complete, which is helpful for comprehensively evaluating the quality of the raw materials, improving the accuracy of raw material screening, and optimizing the detection process, avoiding the step of manually turning over the raw materials, with a high degree of automation, reducing the operation time, and improving the detection efficiency. While the second placement plate 121 is performing the second detection surface detection, the raw materials on the first placement plate 120 can be prepared, that is, new raw materials can be grabbed and placed, thereby improving the utilization rate of the equipment and the continuity of the production line.

[0051] In this embodiment, the first support frame 11 is located above the first placement plate 120 and is provided with a first scanning component. When the raw material 1 to be tested is located on the first placement plate 120, the first scanning component performs a QR code scan on the raw material 1 to correspond the appearance inspection data to the raw material 1 to be tested.

[0052] Specifically, the first detection device 10 further includes a rotating shaft 14 and a first driving component 15; the rotating shaft 14 is rotatably arranged on the detection platform 12 and is located between the first placement plate 120 and the second placement plate 121, and the first placement plate 120 is connected to the rotating shaft 14 on one side close to the second placement plate 121; the output end of the first driving component 15 is connected to one end of the rotating shaft 14 to drive the rotating shaft 14 to drive the first placement plate 120 to flip. Among them, the first driving component 15 is a flip motor. In this way, when the first detection surface of the raw material 1 to be detected on the first placement plate 120 is completed, the first driving component 15 is controlled to drive the rotating shaft 14 to rotate, so that the raw material 1 to be detected is flipped from the first placement plate 120 to the second placement plate 121 and the second detection surface is set upward, without manual intervention, double-sided appearance detection is realized, the automation level of the detection process is improved, and at the same time, the errors of human operation and the time of raw material processing are reduced, and the work efficiency is improved.

[0053] After completing the appearance inspection, since the visual inspection data processing time is much longer than the equipment movement time, in order to improve the product equipment beat, after the inspection is completed, the raw material 1 to be tested continues to perform the next process inspection (thickness measurement). When the thickness measurement is completed, it is fed back to the feeding device 40 through communication. If it is qualified, it will continue to the next process inspection (air tightness). If it is unqualified, the corresponding raw material will be grabbed into the unqualified material bin.

[0054] In this embodiment, the first detection device 10 also includes a first guide rail seat 16 and a second guide rail seat 17. The first guide rail seat 16 is extended along the first direction and is arranged on the first support frame 11. The detection platform 12 is slidably connected to the first guide rail seat 16. The detection platform 12 is connected to a motor component or other power component to drive the detection platform 12 to move along the extension direction of the first guide rail seat 16; the second guide rail seat 17 is extended along the second direction and is arranged on the first support frame 11. The camera component 13 is slidably connected to the second guide rail seat 17. The camera component 13 is connected to a motor component or other power component to drive the camera component 13 to move along the extension direction of the second guide rail seat 17.

[0055] like Figure 3 and Figure 4 As shown, the second detection device 20 includes a second support frame 21, a pad 22 and a thickness measuring assembly 23; the pad 22 is movably arranged on the second support frame 21 along the third direction, and the pad 22 is used to place the raw material 1 to be tested; the thickness measuring assembly 23 is movably arranged on the second support frame 21 along the fourth direction, so as to press the raw material 1 to be tested on the pad 22 and detect the thickness of the raw material 1 to be tested; wherein the third direction and the fourth direction are arranged perpendicular to each other. In this way, the raw material 1 to be tested for appearance inspection is placed on the pad 22 through the feeding device 40, and the raw material 1 to be tested is driven to move along the third direction to a position relative to the thickness measuring assembly 23 by controlling the pad 22, and then the thickness measuring assembly 23 moves along the fourth direction to apply pressure to the raw material 1 to be tested and perform thickness detection on it, so that the pressing force and position of the membrane electrode raw material can be accurately controlled, thereby achieving high-precision thickness measurement and ensuring the consistency and compliance of the raw material thickness. At the same time, this process reduces the multiple movements of raw materials, improves measurement efficiency, and ensures that each raw material is tested for thickness under the same conditions, which improves the accuracy and reliability of the data and helps optimize the raw material screening process.

[0056] In this embodiment, a second scanning component is provided on the second support frame 21. When the raw material 1 to be tested is placed on the pad 22, the second scanning component is used to scan the QR code of the raw material 1 to be tested. If the code scanning is successful, the next material operation (thickness measurement) is performed, and the thickness measurement data is matched with the raw material 1 to be tested.

[0057] Specifically, the second detection device 20 also includes a fixed frame 24, a fixed plate 25 and a second driving component 26; the fixed frame 24 is arranged on the second support frame 21; the fixed plate 25 is movably arranged on the fixed frame 24 along the fourth direction, and the thickness measuring component 23 is arranged on the fixed plate 25; the second driving component 26 is arranged on the fixed frame 24, and the output end of the second driving component 26 is connected to the fixed plate 25, so that when the pad 22 drives the raw material 1 to be measured to move to a position relative to the fixed plate 25, the second driving component 26 drives the fixed plate 25 to drive the thickness measuring component 23 to press the raw material 1 to be measured and detect the thickness of the raw material 1 to be measured.

[0058] In the above configuration, the second driving component 26 is a stepping motor or the like. In this way, the second driving component 26 accurately controls the vertical movement of the fixed plate 25 along the fourth direction, thereby accurately controlling the pressing force of the thickness measuring component 23 on the membrane electrode raw material, which helps to improve the accuracy and consistency of thickness detection and avoid measurement errors caused by uneven pressing force. At the same time, the vertical movement of the fixed plate 25 and the thickness measuring component 23 cooperates with the horizontal movement of the pad 22 to realize the automated process from positioning to thickness measurement of the raw materials, reduce manual operations, and improve production efficiency. In addition, the fixed plate 25 and the thickness measuring component 23 can adapt to the thickness detection requirements of different raw materials. By adjusting the control parameters of the second driving component 26, the pressing force and detection speed can be flexibly adjusted to meet the needs of different raw materials and detection accuracy.

[0059] Specifically, the thickness measuring assembly 23 includes a plurality of pressure side heads and a plurality of displacement sensors 231; a plurality of pressure probes 230 are respectively arranged on the fixed plate 25, so as to be respectively in contact with the raw material 1 to be measured; a plurality of displacement sensors 231 are respectively connected to a plurality of pressure probes 230, so that after the pressure probes 230 apply a preset pressure to the raw material 1 to be measured and compact it, the thickness of the raw material 1 to be measured is detected through the displacement sensors 231. In this way, through the preset pressure, the pressure probe 230 can consistently apply pressure to the raw material 1 to be measured, ensuring the uniformity of pressure during the detection process, which is particularly important for pressure-sensitive raw materials such as membrane electrodes, and can ensure the reliability of thickness detection. By connecting the displacement sensor 231 to the pressure probe 230, the change in the thickness of the raw material 1 to be measured can be accurately measured after the pressure probe 230 contacts the raw material and applies a preset pressure, and high-precision measurement at the micron level can be achieved, greatly improving the accuracy and efficiency of the detection.

[0060] It should be noted that according to the manual of the displacement sensor 231, a downward pressure is applied to the pressure probe 230. The end of the pressure probe 230 away from the displacement sensor 231 is a plane and is used to contact the raw material 1 to be measured. The contact area is a. Since the MEA thickness needs to be detected under a certain pressure, there are multiple pressure probes 230, and the number can be increased according to actual conditions. By adjusting the gravity G of the pressure probe 230, it can be determined based on the pressure of (F+G*g) / a whether it meets the MEA thickness measurement pressure requirement.

[0061] In this embodiment, the second detection device 20 includes a third guide rail seat 27, which is extended along the third direction and arranged on the second support frame 21. The pad 22 is slidably connected to the third guide rail seat 27, and the pad 22 is connected to a motor component or other power component to drive the pad 22 to move along the extension direction of the third guide rail seat 27.

[0062] like Figures 5 to 7 As shown, the third detection device 30 includes a third support frame 31, a first pressing plate 32 and a second pressing plate 33; the first pressing plate 32 is movably arranged on the third support frame 31 along the fifth direction; the second pressing plate 33 is movably arranged on the third support frame 31 along the sixth direction, and the second pressing plate 33 is used to place the raw material 1 to be tested, and the first pressing plate 32 and the second pressing plate 33 are pressed against each other to form a sealed space; wherein the fifth direction and the sixth direction are arranged perpendicular to each other. In this way, the raw material 1 to be tested is driven by the second pressing plate 33 to move along the sixth direction to a position opposite to the first pressing plate 32, and the first pressing plate 32 and the second pressing plate 33 are pressed against each other to form a sealed space under the movement of the first pressing plate 32 along the fifth direction, thereby improving the sealing effect, and then performing airtight detection on the raw material 1 to be tested, so that the airtightness detection is more accurate and reliable. At the same time, the automatic pressing and releasing of the first pressing plate 32 and the second pressing plate 33 realizes the automatic detection of the raw materials, reduces manual operation, and improves the detection efficiency and the automation level of the production line. Moreover, this design can adapt to membrane electrode materials of different sizes and shapes. By adjusting the size and movement range of the pressing plate and controlling the pressing force, the third detection device 30 can flexibly respond to the detection requirements of various raw materials.

[0063] In this embodiment, a third scanning component is provided on the third support frame 31. When the raw material 1 to be tested is placed on the second pressing plate 33, the third scanning component is used to scan the QR code of the raw material 1 to be tested; if the code scanning is successful, the next material operation (airtightness) is performed, and the airtightness data is matched with the raw material 1 to be tested; if the code scanning fails, the raw material 1 to be tested slides relatively on the second pressing plate 33, and the equipment alarms to remind the operator that the material is offset and needs to be manually processed.

[0064] Specifically, the first sealing plate 320 and the second sealing plate 330 are detachably provided on the opposite sides of the first pressing plate 32 and the second pressing plate 33, respectively, and the first sealing plate 320 and the second sealing plate 330 are pressed against each other to form a sealed space; wherein, the first sealing plate 320 is provided with a first ventilation flow channel 321 communicating with the sealed space, and the second sealing plate 330 is provided with a second ventilation flow channel 331 communicating with the sealed space, and the first ventilation flow channel 321 and the second ventilation flow channel 331 are respectively used to connect with an external detection component to perform an airtight detection on the raw material 1 to be tested in the sealed space. In this way, through the precise compression between the first sealing plate 320 and the second sealing plate 330, a highly sealed space can be formed, and external gas will not penetrate, and the external detection component (vacuum pump or gas pressure sensor, etc.) is connected to the first ventilation flow channel 321 and the second ventilation flow channel through the air pipe, respectively, so as to ensure the airtightness test of the membrane electrode raw material, improve the accuracy and reliability of the test results, avoid unnecessary raw material processing steps, and improve the process efficiency of the entire production line.

[0065] In this embodiment, the first sealing plate 320 is detachably connected to the first pressing plate 32 through a quick-plug structure; the second sealing plate 330 is detachably connected to the second pressing plate 33 through a latch. When the first sealing plate 320 and the second sealing plate 330 are worn or damaged, they can be quickly replaced without affecting the operation of the entire third detection device 30, which not only improves the maintenance efficiency of the equipment, but also increases the flexibility of the detection device.

[0066] Specifically, the first sealing plate 320 is provided with a first mounting groove 3201, in which a first elastic pad 3202 is provided, the second pressing plate 33 is provided with a second mounting groove 3301, in which a second elastic pad 3302 is provided, and the first elastic pad 3202 and the second elastic pad 3302 are pressed against each other to form a sealed space; wherein, one end opening of the first ventilation channel 321 is provided at the side of the first sealing plate 320, and the other end opening of the first ventilation channel 321 is provided on the first elastic pad 3202; one end opening of the second ventilation channel 331 is provided at the side of the second sealing plate 330, and the other end opening of the second ventilation channel 331 is provided on the second elastic pad 3302. In this way, when the first pressing plate 32 and the second pressing plate 33 are pressed against each other, the first elastic pad 3202 and the second elastic pad 3302 can be deformed and closely fit the raw material 1 to be tested, forming a tighter sealing effect. The use of the first elastic pad 3202 and the second elastic pad 3302 reduces the hard contact of the raw material 1 to be tested, avoiding hard squeezing or damage to the raw material during the pressing process, especially for a more sensitive raw material such as the membrane electrode, and can effectively protect its integrity and performance.

[0067] In this embodiment, the first sealing gasket and the second sealing gasket are both made of rubber material.

[0068] Because the frame of MEA is made of plastic and the reaction area is made of carbon paper, static electricity and mutual adhesion are easily generated. In actual application, it is very easy to happen that after the airtightness test of MEA is completed, the first pressing plate 32 is lifted and the second pressing plate 33 moves horizontally. After the MEA and the first sealing plate 320 are bonded together, the second pressing plate 33 is laterally displaced relative to the first pressing plate 32, and the MEA falls onto the second pressing plate 33. At this time, the MEA and the second pressing plate 33 are relatively displaced, and the MEA will be damaged when the feeding device 40 grabs the MEA. Therefore, the following multiple methods are used to reduce the adhesion of MEA:

[0069] In this embodiment, a plurality of elastic members 3203 are provided at intervals at the edges of the notches of the first mounting groove 3201 on the first sealing plate 320, respectively, for contacting the raw material 1 to be tested. The elastic members 3203 are micro spring pins. In this way, during the airtightness test, the micro spring structure is squeezed by the MEA, and when the airtightness test is completed, when the first pressing plate 32 is lifted upward, the micro spring structure gives the MEA a downward force, so that the MEA is separated from the first pressing plate 32 and fits the second pressing plate 33.

[0070] In this embodiment, a plurality of blowing holes 3204 are provided at intervals at the edges of the first mounting groove 3201 on the first sealing plate 320, for blowing air to the raw material 1 to be tested. In this way, after the airtightness test is completed, air is blown to the MEA through the plurality of blowing holes 3204, giving the MEA a downward force, so that the MEA is separated from the first pressing plate 32 and attached to the second pressing plate 33.

[0071] In this embodiment, an insulating film layer is provided on the surface of the first sealing plate 320 facing the second sealing plate 330 to reduce the viscosity and electrostatic force between the first pressing plate 32 and the MEA.

[0072] In this embodiment, a plurality of suction holes 3303 are provided at intervals along the edge of the second mounting groove 3301 on the second sealing plate 330 for adsorbing the raw material 1 to be tested. In this way, after the MEA is placed on the second pressing plate 33, vacuum adsorption is performed through the plurality of suction holes 3303, so that the MEA and the second pressing plate 33 are closely attached together.

[0073] In this embodiment, a plurality of stoppers 3304 are provided at intervals on the second sealing plate 330 to limit the position of the raw material 1 to be tested placed on the second sealing plate 330. The stoppers 3304 are spherical positioning pins, so as to ensure that the MEA does not move relative to the specified range.

[0074] Specifically, the third detection device 30 also includes a mounting frame 34, a mounting plate 35 and a third driving component 36; the mounting frame 34 is arranged on the third support frame 31; the mounting plate 35 is movably arranged on the mounting frame 34 along the fifth direction, and the first pressing plate 32 is arranged on the mounting plate 35; the third driving component 36 is arranged on the mounting frame 34, and the output end of the third driving component 36 is connected to the mounting plate 35, so that when the second pressing plate 33 moves to a position opposite to the first pressing plate 32, the third driving component 36 drives the mounting plate 35 to drive the first pressing plate 32 to press the second pressing plate 33, so as to perform airtight detection on the raw material 1 to be tested. Among them, the third driving component 36 is a stepping motor, etc., and the driving shaft of the third driving component 36 is connected to a pressure sensor, and is connected to the mounting plate 35 through the pressure sensor. In this way, the pressing force of the first pressing plate 32 on the second pressing plate 33 can be accurately adjusted to ensure the formation of a stable and reliable sealing space, thereby improving the accuracy and consistency of airtight detection. The mounting plate 35 drives the automatic control of the first pressing plate 32, so that the entire airtightness detection process does not require human intervention, reduces the errors that may be introduced by human operation, and improves the detection efficiency.

[0075] In this embodiment, the third detection device 30 also includes a fourth guide rail seat 37, which is arranged on the third support frame 31 and extends along the sixth direction. The second pressure plate 33 is slidably connected to the fourth guide rail seat 37, and the second pressure plate 33 is connected to a motor component or other power component to drive the second pressure plate 33 to move along the extension direction of the fourth guide rail seat 37.

[0076] like Figure 8 and Fig. 9 As shown, the feeding device 40 includes a fourth support frame 41 and a grabbing assembly 42; the grabbing assembly 42 is movably arranged on the fourth support frame 41 along the seventh direction and the eighth direction respectively, and the grabbing assembly 42 includes a plurality of first suction nozzles 420 for adsorbing the raw material 1 to be tested and transferring it between the first detection device 10, the second detection device 20 and the third detection device 30; wherein the seventh direction and the eighth direction are arranged perpendicular to each other. With the above arrangement, the grabbing assembly 42 can automatically transfer the raw materials between the first detection device 10, the second detection device 20 and the third detection device 30, eliminating the process of manual handling, and significantly improving the degree of automation and production line efficiency. And through the precise positioning movement of the grabbing assembly 42 in the vertical and horizontal directions, the accurate placement of the raw material 1 to be tested during the detection process can be ensured, the detection accuracy is improved, and the flexibility and adaptability of the entire detection system are improved.

[0077] Specifically, the gripping assembly 42 includes a main frame 421, two suction cups 422 and a fourth driving component 424; the main frame 421 is movably connected to the fourth support frame 41; the two suction cups 422 are movably arranged on the main frame 421 along the vertical direction, and a plurality of first suction nozzles 420 are arranged on the suction cups 422 at intervals along the circumferential direction of the suction cups 422, and a plurality of second suction nozzles 423 are also arranged on the suction cups 422 to adsorb the separation paper between two adjacent raw materials 1 to be tested; the fourth driving component 424 is arranged on the main frame 421, and the plurality of first suction nozzles 420 and the plurality of second suction nozzles 423 are respectively connected to the fourth driving component 424 to drive the first suction nozzles 420 and the second suction nozzles 423 to perform negative pressure adsorption. Among them, the fourth driving component 424 is a vacuum device.

[0078] With the above arrangement, the first suction nozzle 420 and the second suction nozzle 423 on the two suction cups 422 can respectively and accurately grasp the membrane electrode raw material and the separator paper between two adjacent membrane electrode raw materials. Through the negative pressure adsorption of the first suction nozzle 420 and the second suction nozzle 423, the stable grasping and accurate placement of the raw material 1 to be tested and the separator paper are guaranteed, and the displacement or damage of the raw material 1 to be tested during transportation is avoided. The design of the second suction nozzle 423 can realize the automatic adsorption and placement of the separator paper, which is conducive to the recycling and reuse of the separator paper, reduces the production cost, and improves the utilization rate of the raw material 1 to be tested. In addition, the use of a suction nozzle for grasping avoids the possible contamination of the raw material 1 to be tested by direct mechanical contact, especially when processing membrane electrode raw materials with high cleanliness requirements, which can effectively protect the cleanliness of the raw material 1 to be tested and reduce damage. At the same time, multiple first suction nozzles 420 and multiple second suction nozzles 423 can also adapt to raw materials 1 to be tested of different sizes and shapes, enhancing the flexibility and adaptability of the entire detection system.

[0079] In this embodiment, the feeding device 40 also includes a fifth guide rail seat 43 and a sixth guide rail seat 44. The fifth guide rail seat 43 is extended along the seventh direction and is arranged on the fourth support frame 41. The sixth guide rail seat 44 is slidably connected to the fifth guide rail seat 43. The sixth guide rail seat 44 is connected to a motor component or other power component to drive the sixth guide rail seat 44 to move along the extension direction of the fifth guide rail seat 43; the sixth guide rail seat 44 is extended along the eighth direction and is arranged on the fifth guide rail seat 43. The grabbing assembly 42 is slidably connected to the sixth guide rail seat 44. The grabbing assembly 42 is connected to a motor component or other power component to drive the grabbing assembly 42 to move along the extension direction of the sixth guide rail seat 44.

[0080] like Fig.10As shown, the membrane electrode raw material detection system also includes a loading device 50, which is arranged between the first detection device 10 and the feeding device 40. The loading device 50 includes a fifth support frame 51 and a loading bin assembly 52 for stacking and accommodating a plurality of raw materials 1 to be tested in sequence. The loading bin assembly 52 is movably arranged on the fifth support frame 51 in a vertical direction, so that the feeding device 40 can grab the raw material 1 to be tested when the loading bin assembly 52 moves to a preset position; wherein, there are two loading bin assemblies 52. In this way, the design of the double loading bin assembly 52 ensures the continuity of the supply of the raw material 1 to be tested. When one loading bin assembly 52 is in the raw material grabbing stage, the other can be replenished, thereby avoiding production pauses and ensuring the continuous operation of the production line. At the same time, the automatic docking between the loading bin assembly 52 and the feeding device 40 reduces the waiting time of the raw materials on the detection line and improves the raw material flow speed and detection efficiency.

[0081] Since the MEA material is usually thick in the middle and thin around the edges, the surface of the MEA has a certain amount of static electricity and stickiness; in order to ensure the flatness of the material, a piece of MEA material and a piece of separator paper are often stacked on each other. If the stickiness of the MEA surface is too high, the next piece of material to be grabbed will be grabbed together with the previous piece of material, and the next piece will fall at some point because it is not adsorbed by the first suction nozzle 420, resulting in a slight position deviation; when the first suction nozzle 420 grabs the piece, the MEA will be double squeezed by the upper bin assembly 52 limit and the suction cup 422, damaging the MEA.

[0082] In order to prevent damage to the MEA, the loading bin assembly 52 includes a bearing plate 520, a plurality of limiting posts 521 and a brush component 522; the bearing plate 520 is movably arranged on the fifth support frame 51 in the vertical direction, and the bearing plate 520 is used to stack a plurality of raw materials 1 to be tested in sequence; a plurality of limiting posts 521 are respectively arranged on the fifth support frame 51 at intervals and surround the bearing plate 520, so as to limit the plurality of raw materials 1 to be tested located on the bearing plate 520; the brush component 522 is arranged on one side of the bearing plate 520, so as to separate the raw materials 1 to be tested adjacent to it when the feeding device 40 grabs the raw materials 1 to be tested. The brush component 522 is connected to the fifth support frame 51 by bolts, and the relative displacement of the brush structure assembly can be adjusted by fine-tuning the position of the bolts.

[0083] In the above arrangement, the function of the brush component 522 is to effectively separate other adjacent raw materials when the feeding device 40 grabs a piece of raw material, avoid adhesion between the raw materials, ensure that the raw material grabbed each time is a single piece, and reduce the processing complexity and potential damage caused by the adhesion of raw materials. Specifically, the soft hair of the brush component 522 is inserted between two adjacent MEA materials. Because the vacuum suction force of the suction cup 422 is much greater than the force of the brush component 522 when grabbing the MEA sheet, the MEA sheet and the separator paper are adsorbed and grabbed by the suction cup 422, while the lower MEA is not sucked by the suction cup 422, and is left on the carrier plate 520 under the force of the brush, and the corresponding position does not change. Therefore, the brush component 522 can effectively ensure the integrity of the material, reduce the failure rate, and improve the stability and reliability of the entire detection system.

[0084] In this embodiment, the loading device 50 also includes a seventh guide rail seat 53, which is extended in the vertical direction on the fifth support frame 51, and the loading bin assembly 52 is slidably connected to the seventh guide rail seat 53. The loading bin assembly 52 is connected to a motor component or other power component to drive the loading bin assembly 52 to move in the vertical direction.

[0085] In this embodiment, the membrane electrode material detection system further includes a first material receiving bin 60 and a second material receiving bin; the first material receiving bin 60 is provided between the third detection device 30 and the feeding device 40, and is used to collect the raw material 1 to be tested that has completed the detection; the second material receiving bin is provided between the loading device 50 and the first detection device 10, and is used to collect the separation paper between two adjacent raw materials 1 to be tested. In this way, when the feeding device 40 grabs a piece of MEA material and separation paper from the loading bin assembly 52 and transfers them to the first detection device 10 for detection, when passing through the second material receiving bin, the second suction nozzle 423 on the suction cup 422 is closed for adsorption, so that the separation paper falls into the second material receiving bin for collection.

[0086] In this embodiment, the membrane electrode raw material detection system also includes a paper separator bin and a waste bin; the paper separator bin is used to accommodate paper separators; the waste bin is used to collect unqualified MEA materials after detection by the first detection device 10, the second detection device 20, or the third detection device 30.

[0087] In this application, the specific implementation method is:

[0088] The feeding device 40 is started, and the suction cup 422 grabs the MEA from the upper bin assembly 52 and places it on the first detection device 10, and at the same time returns to the upper bin assembly 52 to grab the next piece; a waiting position is provided between the upper bin assembly 52 and the first detection device 10 (the second receiving bin is set at the waiting position, the second suction nozzle 423 on the suction cup 422 is deflated, and the spacer paper falls into the second receiving bin due to its own gravity), and after the suction cup 422 grabs the next piece of MEA, it moves to the waiting position on the first detection device 10 and remains motionless; after waiting for the MEA on the first detection device 10 to be inspected, the suction cup 422 grabs the inspected MEA material (qualified / unqualified) and places it on the second detection device 20, and at the same time places the next piece of MEA on the first detection device 10 for appearance inspection.

[0089] The grabbing assembly 42 moves, controls the suction cup 422 to drive the MEA to move to the second detection device 20, and places the MEA that has passed the inspection of the first detection device 10 on the pad 22 for thickness measurement; after the thickness measurement is completed, if both the thickness measurement and the appearance inspection are qualified, the suction cup 422 grabs the MEA material and moves it to the third detection device 30; if it is unqualified, the MEA material is grabbed and placed in the waste bin.

[0090] After the air-tightness test is completed, the suction cup 422 moves to the third detection device 30. If the air-tightness is qualified, the MEA material is grabbed into the second material receiving bin; if the air-tightness is unqualified, the MEA material is grabbed into the waste bin; after the suction cup 422 places a piece of qualified MEA material into the first material receiving bin 60, a piece of separator paper is grabbed from the separator paper bin and placed in the first material receiving bin 60 at the same time, so that the separator paper and MEA material are staggered and stacked, which is convenient for subsequent production stacking and direct loading.

[0092] The membrane electrode raw material detection system includes a detection device and a feeding device 40; the detection device includes a first detection device 10, a second detection device 20 and a third detection device 30 arranged in sequence along the preset process flow direction; the feeding device 40 is arranged on one side of the detection device, so as to transfer the raw material 1 to be tested between the first detection device 10, the second detection device 20 and the third detection device 30; wherein the first detection device 10 is used to detect the outer surface of the raw material 1 to be tested and determine whether the raw material 1 to be tested is qualified; the second detection device 20 is used to detect the thickness of the raw material 1 to be tested; the third detection device 30 has a sealed space for accommodating the raw material 1 to be tested, so as to perform airtightness detection on the raw material 1 to be tested in the sealed space. In this way, through the integrated first detection device 10, the second detection device 20 and the third detection device 30, the appearance, thickness and airtightness of the membrane electrode raw material are automatically detected, which significantly improves the detection efficiency and accuracy compared with manual detection, reduces the error and pollution risks caused by human operation, and thus solves the problem of low efficiency of qualified detection of membrane electrode incoming materials using semi-automatic manual detection in the prior art. At the same time, this comprehensive inspection ensures that the quality of the raw materials meets the standards before entering the fuel cell stack production, thereby improving the performance and reliability of the final product. And through the coordinated work of the feeding device 40 and the detection equipment, the raw materials to be tested 1 can be seamlessly transferred between different detection devices, realizing a continuous production process, avoiding interruptions to the production line, ensuring production efficiency and stable operation of the production line, and by eliminating unqualified raw materials at an early stage, reducing the rework costs caused by raw material quality problems in the later stage of production, and improving the overall production economic benefits.
