[0031] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only 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 making creative efforts are within the scope of protection of the present invention.

[0032] Reference Figures 1 to 3The utility model provides an embodiment: a membrane electrode defect rapid screening device, including a body 1, a console 2 is fixedly connected to the right side of the body 1, and the console 2 is used to control the body 1 to perform rapid scanning and screening of membrane electrode defects. The front end of the body 1 is fixedly connected to a material receiving assembly for loading materials, and the material receiving assembly includes two connecting blocks 3. The rear end of the connecting block 3 is fixedly connected to the front end of the body 1. The body 1 here provides a stable support for the connecting block 3. The front ends of the two connecting blocks 3 are fixedly connected to a front box 4. The connecting blocks here 3 is used to connect the machine body 1 and the front box 4 together. Two brackets 5 are fixedly connected to the front side of the top of the front box 4. The top of the bracket 5 is rotatably connected to the feeding roller 6. The bracket 5 here provides stable support for the feeding roller 6. The inner wall of the material-bearing component is fixedly connected to the cross plate 7. The top of the cross plate 7 is fixedly connected to a driving component for providing power. The driving component includes a fixed sleeve 8. The bottom end of the fixed sleeve 8 is fixedly connected to the top of the cross plate 7. The inner wall of the fixed sleeve 8 is fixedly connected to the cylinder 9. The fixed sleeve 8 here can protect the cylinder 9.

[0033] The bottom end of the cylinder 9 is fixedly connected to the top of the cross plate 7. The fixed sleeve 8 here and the cross plate 7 together provide a stable support for the cylinder 9. The driving end of the driving assembly is fixedly connected with a slide plate 10. Both ends of the slide plate 10 are slidably connected to the inner wall of the front box 4. The cylinder 9 here can drive the slide plate 10 here to move up and down after starting. The bottom of both ends of the slide plate 10 is fixedly connected with a support plate 11. The outer side of the support plate 11 is slidably connected to the inner wall of the front box 4. When the slide plate 10 moves up and down, it can drive the support plate 11 here to slide on the inner wall of the front box 4. When moving downward, the outer side of the support plate 11 is movably connected to two balls 12, and the outer side of the balls 12 is movably connected to the inner wall of the front box 4. The balls 12 here make the sliding process smoother, thereby improving the speed of adjusting the tension. The inner wall of the top of the slide plate 10 is rotatably connected to the rotating shaft 13, and the outer side of the rotating shaft 13 is fixedly connected to the tensioning roller 14. The slide plate 10 here is U-shaped. When the slide plate 10 moves up and down, it can drive the rotating shaft 13 and the tensioning roller 14 here to move up and down, thereby achieving the purpose of adjusting the tension required by different membrane electrode products.

[0034] Reference Figures 4 and 5The inner side of the connecting block 3 is rotatably connected to a turntable 15, and the adjacent side of the two turntables 15 is fixedly connected to a bottom box 16. The turntable 15 here enables the bottom box 16 to rotate adaptively according to the position of the membrane electrode. The inner wall of the bottom box 16 is slidably connected to a limit block 17, and the top of the limit block 17 is fixedly connected to a plurality of springs 18. The other end of the spring 18 is fixedly connected to one side of the inner wall of the bottom box 16. The limit block 17 and the bottom box 16 here provide a stable support for the spring 18, so that it remains stable during expansion and contraction. The bottom end of the limit block 17 is fixedly connected to a rubber block 19, and the limit block 17 here ensures that the rubber block 19 will not accidentally escape from the inner wall sliding space of the bottom box 16. The outer side of the rubber block 19 is slidably connected to the inner wall of the bottom box 16, and the inner wall of the rubber block 19 is slidably connected to a slide bar 20. The slide bar 20 here is inserted into the bottom end of the rubber block 19 here, and the bottom end of the slide bar 20 is fixedly connected to a rotating box 21.

[0035] The outside of the rotating box 21 is slidably connected to the inner wall of the bottom box 16, and the inner wall of the rotating box 21 is rotatably connected to a sticky roller 22. The sticky roller 22 here can adhere to the dust on the surface of the membrane electrode before detection, so as to prevent the equipment from misjudging during subsequent detection and causing wrong detection results, thereby achieving the purpose of improving detection accuracy; at the same time, after the surface of the sticky roller 22 is full of dust, it can be pulled out by the slide bar 20, cleaned or replaced, thereby increasing its service life and ensuring high detection accuracy for a long time. Two unloading rollers 23 are fixedly connected to the top of the body 1. The unloading rollers 23 here are used to collect membrane electrodes that have no problems after detection.

[0036] Working Principle: During the loading phase, the membrane electrode is wound onto a loading roller 6 mounted on a support 5. The loading roller 6 helps transport the membrane electrode to the designated location. This process ensures that the membrane electrode can smoothly enter the inspection area, laying the foundation for subsequent inspection work.

[0037] Next comes the tension adjustment stage. Actuating the cylinder 9, protected by a fixed sleeve 8, drives the slide 10 up and down, thereby driving the support plate 11 and the inner wall of the front box 4, which in turn drives the rotating shaft 13 and tensioning roller 14 to adjust the tension of the membrane electrode. This step is crucial because the required membrane electrode tension varies depending on the product. Excessive tension can fracture the fragile membrane electrode, thereby reducing product quality.

[0038] Before the membrane electrode is transferred to the interior of the body 1 for scanning, it will first pass under the sticky roller 22. At this time, under the action of the spring 18 and the limit block 17, it is tightly fitted with the membrane electrode, thereby removing dust and other impurities on the surface of the membrane electrode. This step cannot be ignored, because the dust and impurities on the surface may interfere with the scanning results of the detection equipment inside the body 1, resulting in misjudgment or missed detection. Through the cleaning effect of the sticky roller 22, the equipment can ensure that the surface of the membrane electrode is clean and tidy, thereby improving the detection accuracy. After the surface of the sticky roller 22 is full of dust, it can be pulled out of the inner wall of the rubber block 19 by the slider 20, and then it can be cleaned or replaced, thereby increasing its service life and ensuring high detection accuracy for a long time.

[0039] After entering the defect detection stage, the membrane electrode is cleaned and tensioned before entering the detection area. At this time, the control console 2 can control the detection equipment inside the body 1 to quickly scan the surface of the membrane electrode to identify possible defects.

[0040] During the unloading and collecting stage, the membrane electrode after inspection is collected by the unloading roller 23.

[0041] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or make equivalent replacements for some of the technical features therein. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
