[0018] The subject matter described herein will now be discussed with reference to exemplary embodiments. It should be understood that these embodiments are discussed merely to enable those skilled in the art to better understand and implement the subject matter described herein. Furthermore, features described in some examples may be combined in other examples.

[0019] like Figures 1 to 5 , Figures 7 to 10 As shown, the automatic inspection device for graphene continuous film materials includes: Tensioning film feeding mechanism 1, which includes a frame 101, a film conveying assembly 1 disposed on the frame 101, and an adjustable tensioning assembly. Parallel film feeding mechanism 2, which includes frame 201 and film material conveying assembly 2 disposed on frame 201, wherein the input end of the film material conveying assembly is correspondingly disposed to the output end of the adjustable tensioning assembly; The follow-up tensile testing mechanism 3 includes two sets of symmetrically mounted circulating moving components on the second frame 201, a drive component on the second frame 201, several sets of tensile performance testing components, and a power supply component on the second frame 201. The several sets of tensile performance testing components are evenly connected to the two sets of circulating moving components. The tensile performance testing components located within a set range in the parallel area on the circulating moving components are used to apply a set tensile force along the width direction of the graphene continuous film and detect the change parameter of the tensile force value in real time. The power supply component is used to make electrical contact with the tensile performance testing components located within the set range in the parallel area on the circulating moving components. The drive component is used to drive the two sets of circulating moving components to run synchronously.

[0020] The membrane material conveying assembly includes a roller mounting frame 103 connected to a frame 101, two conveying rollers 104 movably mounted on the roller mounting frame 103, a motor 105 fixedly mounted on the roller mounting frame 103, a transmission wheel 106 connected to the shaft of one of the conveying rollers 104, and a transmission wheel 107 connected to the output end of the motor 105. The transmission wheel 106 and the transmission wheel 107 mesh with each other. An electrical control box 102 is mounted on the frame 101, and the motor 105 is electrically connected to the electrical control box 102. The adjustable tensioning assembly includes several guide rods 108 that are detachably connected to the frame 101.

[0021] The membrane material conveying assembly includes a guide rod 202 mounted on the frame 201 and two fixed supports 203, a platform plate 204 fixedly connected between the two fixed supports 203, several driven wheels 205 movably mounted on the platform plate 204, a movable support 206 slidably connected to the fixed supports 203, a drive roller 207 movably connected between the two movable supports 206, a motor 208 fixedly mounted on one of the movable supports 206, and a cylinder 209 connected to the fixed support 203. The output end of the cylinder 209 is fixedly connected to the movable support 206, and the output end of the motor 208 is connected to the movable support 206.

[0022] It should be noted that, based on the production parameters of the continuous graphene membrane, multiple guide rods 108 in the tensioning membrane feeding mechanism 1 are installed on the frame 101 according to the parameters. The continuous membrane is conveyed by two conveying rollers 104. Under the adjustment of the multiple guide rods 108, the membrane is tensioned to a set tension. The membrane with the set tension and conveying speed is conveyed towards the follow-up tensile testing mechanism 3 through the cooperation of the active roller 207 and driven wheel 205 on the frame 201. During the membrane conveying process, the drive assembly drives two sets of symmetrically distributed circulating moving components to move synchronously and cyclically at the same speed as the membrane conveying. Multiple tensile performance testing components on the circulating moving component follow the circulating moving component in a circular motion. When the corresponding tensile performance testing component moves to the power supply component and makes electrical contact with the power supply component, it starts to run according to the set program, moves towards the membrane material and clamps the membrane material. After clamping, it pulls back with a set tensile force. That is, the two symmetrical tensile performance testing components apply symmetrical tensile force to the membrane material along the width direction of the membrane material and acquire the current tensile force change data in real time to obtain the tensile performance parameters of the membrane material area corresponding to the current clamping position. Thus, it is possible to perform traversal tensile performance testing on continuous membrane materials without affecting the membrane material production efficiency.

[0023] In an optional embodiment of the invention, such as Figures 7 to 9 As shown, the circulating moving assembly includes two sets of movable shafts 308 mounted on frame 201, sprockets 309 fixedly connected to the movable shafts 308, and chains 310 connected between the two sprockets 309. Several support rods 318 are connected between the two sets of chains 310, and the support rods 318 and several tensile performance testing components are alternately distributed.

[0024] The drive assembly includes a motor 301 fixedly mounted on frame 201, a movable shaft 302 movably mounted on frame 201, a sprocket 303 connected to the movable shaft 302, a sprocket 304 connected to the output end of motor 301, a chain 305 connected between sprocket 303 and sprocket 304, two sprockets 306 symmetrically connected to the movable shaft 302, two sprockets 311 respectively connected to the movable shaft 308, and a chain 307 connected between sprockets 306 and sprockets 311. The two sprockets 311 are respectively connected to the two movable shafts 308 close to the movable shaft 302.

[0025] It should be noted that when the two sets of circulating moving components are driven synchronously by the drive assembly, the motor 301 drives the sprocket 304 to rotate. When the sprocket 304 rotates, it drives the mating sprocket 303 to rotate via the connected chain 305. Since the sprocket 303 is fixedly connected to the movable shaft 302, when the sprocket 303 rotates, it drives the movable shaft 302 to rotate in the same direction and angle, and drives the two sprockets 306 connected to the movable shaft 302 to rotate synchronously. When the two sprockets 306 rotate, they drive the matching sprocket 311 to rotate synchronously via the connected chain 207. The rotation of sprocket 311 drives the movable shaft 308 connected to it and the sprockets on the movable shaft 308. The fourth sprocket 309 rotates synchronously, and when the fourth sprocket 309 rotates, it drives the third sprocket 310 to move cyclically through another matching fourth sprocket 309. The horizontal movement area of ​​the third sprocket 310 is divided into an upper area and a lower area. The tensile performance testing component located in the upper area, within a set movement range, can pass through the power supply component and maintain electrical contact with it while following the horizontal movement of the third sprocket 310. During this process, the tensile performance of the membrane material is tested. Before disengaging from the power supply component, the tensile performance testing component ends the test and resets to its initial position. It continues until the next cycle when it contacts the power supply component to start a new tensile performance test, obtaining the tensile performance parameters of the corresponding membrane material area.

[0026] In an optional embodiment of the invention, such as Figures 7 to 10 As shown, the tensile performance testing component includes a connecting frame 312 connected to the chain 310, an electric telescopic rod 313 detachably connected to the connecting frame 312, a tension / compression sensor 314 connected to the output end of the electric telescopic rod 313, an electrically controlled gripper 315 connected to the tension / compression sensor 314, and a rigid conductive component 316 connected to the electric telescopic rod 313. The rigid conductive component 316 is used for electrical contact with the power supply component. The electric telescopic rod 313, the tension / compression sensor 314 connected to the output end of the electric telescopic rod 313, and the electrically controlled gripper 315 connected to the tension / compression sensor 314 are all electrically connected to the rigid conductive component 316.

[0027] The power supply assembly includes two power supply boards 317 symmetrically connected to the frame 201. Each power supply board 317 is provided with a moving groove for moving a corresponding rigid conductive component 316. The inner wall of the moving groove is provided with a conductive metal strip that cooperates with the corresponding rigid conductive component 316.

[0028] It should be noted that when the electric telescopic rod 313 in the tensile performance testing component moves with the chain 310, the rigid conductive part 316 on the electric telescopic rod 313 will contact the power supply board 317 and start to supply power to the electric telescopic rod 313, the tension and compression sensor 314, and the electronically controlled gripper 315. The electric telescopic rod 313 and the electronically controlled gripper 315 will start to operate synchronously under the drive of the set program. The electric telescopic rod 313 drives the tension and compression sensor 314 and the electronically controlled gripper 315 to move synchronously toward the membrane material. The electronically controlled gripper 315 opens under the control of the program, and when the electric telescopic rod 313 moves it to the place where it matches the membrane material, it begins to close and clamp the corresponding area of ​​the membrane material. After clamping, the electric telescopic rod 313 pulls back and begins to apply tension to the tension and compression sensor 314 until the tension value reaches the set parameter, and then determines the current reset distance of the electric telescopic rod 313, thereby determining whether the tensile performance of the membrane material in the corresponding area meets the standard.

[0029] In an optional embodiment of the invention, such as Figure 3 , Figure 6 and Figure 11 As shown, it also includes a traversal electrical performance testing mechanism 4, which includes a biaxial moving platform mounted on the second frame 201 and an electrical performance testing component connected to the biaxial moving platform. The biaxial moving platform is used to drive the electrical performance testing component to move along the length and / or height direction of the second frame 201. The electrical performance testing component is used to detect the electrical performance parameters of a set area of ​​the graphene continuous film.

[0030] The dual-axis moving platform includes a slide rail 401 mounted on a frame 201, a sliding frame 402 slidably connected to the slide rail 401, a wheel frame 403 fixedly mounted on one end of the slide rail 401, a transmission wheel 404 movably mounted on the wheel frame 403, a motor 405 fixedly mounted on the wheel frame 403, a wheel frame 406 fixedly mounted on the other end of the slide rail 401, a transmission wheel 407 movably mounted on the wheel frame 406, a synchronous belt 408 connecting the transmission wheel 404 and the transmission wheel 407, a cylinder 409 fixedly connected to the sliding frame 402, and a connecting plate 410 connected to the output end of the cylinder 409. The sliding frame 402 is fixedly connected to the synchronous belt 408, and the output end of the motor 405 is connected to the transmission wheel 404. The slide rail 401 is arranged along the length of the frame 201, and the cylinder 409 is arranged along the height of the frame 201.

[0031] It should be noted that, in order to detect the changes in electrical performance parameters of the membrane material under no stress and under different degrees of tensile force, a biaxial moving platform is set up to drive the electrical performance detection component to move along the length and height directions of frame 201, thereby adapting to the movement of the membrane material. During its movement, it performs traversal electrical performance detection on a set area. During the detection process, it works in conjunction with the tensile performance detection component to apply tensile force to the membrane material, obtaining data on the changes in the electrical performance parameters of the membrane material as the stress value gradually changes in the current area under no stress and under stress. When controlling the movement of the electrical performance detection component along the length and / or height directions of frame 201, motor 405 drives transmission wheel 404. When the transmission wheel 3 404 rotates, it can cooperate with the transmission wheel 407 to drive the synchronous belt 408 to move along the length of the frame 201. During the movement, it drives the sliding frame 402 fixedly connected to it to move synchronously, thereby driving the cylinder 2 409 connected to the sliding frame 402 and the connecting plate 410 connected to the output end of the cylinder 2 409 to move synchronously along the length of the frame 201. When controlling the connecting plate 410 and the electrical performance detection component installed on the connecting plate 410 to move along the height of the frame 201, the cylinder 2 409 can drive the connecting plate 410 to move along the height of the frame 201, thereby controlling the contact between the electrical performance detection component and different areas of the membrane material.

[0032] In an optional embodiment of the invention, such as Figure 3 , Figure 6 As shown, the electrical performance testing component includes two sets of slide rails 411 symmetrically connected to the connecting plate 410, a motor 412 fixedly installed on the slide rails 411, a slider 413 slidably connected to the slide rails 411, a lead screw movably installed inside the slide rails 411, and two sets of probes 414 connected to the slider 413. The output end of the motor 412 is connected to the lead screw, and the slider 413 is threadedly connected to the lead screw. The slide rails 411 are arranged along the width direction of the frame 201.

[0033] It should be noted that when testing the electrical properties of the membrane material, the four-probe method is used, with four probes 414 combined in pairs to measure the current and voltage. The sheet resistance or resistivity of the material is calculated according to the formula. When testing different areas, the corresponding motor 412 can drive the lead screw connected to it to rotate. When the lead screw rotates, it drives the slider 413 connected to it to move a set distance along the width direction of the frame 201, thereby realizing traversal testing.

[0034] In an optional embodiment of the present invention, a puncture needle may be added to the slider 413 to obtain the puncture resistance of the membrane material during the process of the gradual change of the force value in the current area under no force and under force.
