All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0020] Please refer to Figures 1-3, the present invention provides a technical solution: an intelligent automated graphene electrothermal film withstand voltage testing device, including truss one 1, truss two 2 and truss three 5. There is a truss two 2 on the right side of truss one 1, and there is a truss three 5 on the right side of truss two 2. There are conveyor belts 6 horizontally arranged on the tops of truss one 1, truss two 2 and truss three 5, and drive motors 7 are installed on the right front sides of the conveyor belts 6. There are two front and rear mounting plates one 10 fixed on the right side of the top of truss one 1 and the left side of the top of truss three 5, and there are limit slots 18 installed on the tops between the mounting plates one 10. There are pushing cylinders 21 fixed inside the limit slots 18, and the output ends of the pushing cylinders 21 are fixedly connected to the tops of scraping plates 22. And displacement sensors 23 are installed at the left ends of the scraping plates 22. There are two front and rear mounting plates two 11 fixed on the top between truss one 1 and truss two 2, and a two-way cylinder 26 is installed on the top between the mounting plates two 11. There are pressing cylinders 25 fixed on the left and right side walls in the middle of the two-way cylinder 26, and the output ends of the pressing cylinders 25 are fixedly connected to the tops of three detection tentacles 24. And there is a detector 12 directly below the detection tentacles 24. A main controller 17 is installed on the left rear side of the top of truss three 5. The model of this main controller 17 can be TC55A. The model of this drive motor 7 can be MR-J2S-20A. The models of this three-axis cylinder 14 and the discharging cylinder 27 can both be MGGLB32-100. The models of this lifting cylinder 15, pushing cylinder 21 and pressing cylinder 25 can all be SC160-50. The model of this two-way cylinder 26 can be YNT-05. And the input ends of the drive motor 7, three-axis cylinder 14, lifting cylinder 15, pushing cylinder 21, pressing cylinder 25, two-way cylinder 26 and discharging cylinder 27 are electrically connected to the output end of the PLC controller inside the main controller 17. The model of this displacement sensor 23 can be HG-C1050. And the output end of the displacement sensor 23 is electrically connected to the input end of the PLC controller inside the main controller 17.

[0021] As Figure 1 and Figure 2 In the right sides of truss two 2 and truss three 5, there are respectively a waste bin 4 and a finished product bin 9. And there are respectively a blanking plate one 3 and a blanking plate two 8 installed on the rear side wall of truss two 2 and the right side wall of truss three 5. And the right ends of the blanking plate one 3 and the blanking plate two 8 respectively extend obliquely into the inside of the waste bin 4 and the finished product bin 9, which is convenient for the automatic sliding and warehousing of unqualified products and finished products.

[0022] As Figure 1 and Figure 2 On the rear side wall of the top of truss two 2, there is a mounting frame 13 fixed. And at the top of the mounting frame 13, there is a three-axis cylinder 14 fixed. The output end of the three-axis cylinder 14 is equipped with two left and right lifting cylinders 15. And at equal intervals on the output ends of the lifting cylinders 15, there are a number of vacuum suction cups 16 fixed, which are used for adsorptive screening of unqualified products.

[0023] As Figure 3 On the front side wall at the top of the middle truss two 2, a material discharging cylinder 27 is fixed, and a push plate 28 is installed at the output end of the material discharging cylinder 27 for pushing out unqualified products by screening.

[0024] As Figure 1 In it, the conveyor belts 6 are all horizontally distributed and close to each other, and the conveyor belts 6 all rotate and drive in the clockwise direction for continuous material feeding to reduce manual intervention.

[0025] As Figure 1 On the left and right sides between the first mounting plates 10, guide rails 19 are installed. At the same time, linear bearings 20 are fixed on the left and right sides at the top of the scraping plate 22. Moreover, the guide rails 19 and the linear bearings 20 are nested with each other to form a sliding connection structure for improving stability.

[0026] Working principle: When in use, as shown in the attached Figure 1 and the attached Figure 2 , first, by operating the main controller 17, the testing equipment is powered on and runs. Among them, the three drive motors 7 run synchronously to make the conveyor belts 6 rotate uniformly in the clockwise direction. At this time, the staff stands at the left end of the first truss 1 and places the graphene electric heating films to be detected on the surface of the conveyor belts 6 in turn. When the graphene electric heating film is about to reach between the first mounting plates 10, under the monitoring of the displacement sensor 23, if the arrangement of the graphene electric heating film is relatively scattered, the pushing cylinder 21 in the limiting groove 18 pushes the scraping plate 22 back and forth to make the graphene electric heating film arranged neatly. During this process, the guide rails 19 and the corresponding linear bearings 20 maintain a sliding connection for improving the stability of the scraping plate 22;

[0027] Subsequently, the graphene electric heating film passes between the second mounting plates 11. At this time, the double-acting cylinder 26 moves back and forth to make the detection tentacles 24 correspond to the graphene electric heating film. Then, the pressing cylinder 25 extends downward to press the detection tentacles 24 against the graphene electric heating film and complete the high-voltage breakdown test within a few seconds. Then, the detector 12 transmits the data back to the main controller 17 for analysis and backup. Then, as shown in the attached Figure 2 and the attached Figure 3 , the graphene electric heating film passes in front of the mounting frame 13. At this time, the qualified finished products continue to be transmitted to the right and finally slide into the finished product bin 9 through the second blanking plate 8. For unqualified products, there are two screening schemes. One is that the three-axis cylinder 14 and the lifting cylinder 15 drive the vacuum suction cup 16 to move horizontally and vertically, so that the vacuum suction cup 16 sucks up the unqualified products and brings them back above the first blanking plate 3, or the material discharging cylinder 27 directly drives the push plate 28 to push the unqualified products onto the first blanking plate 3 and finally slide into the waste bin 4 to wait for centralized processing later. In this way, finally, all the work of the intelligent and automated graphene electric heating film withstand voltage testing equipment is completed.

[0028] In summary, the intelligent automated graphene electrothermal film withstand voltage test equipment realizes functions such as automatic feeding, limiting, detection, and screening of the withstand voltage test equipment, thereby greatly improving the withstand voltage test efficiency of the graphene electrothermal film.
