Description

Technical Field

[0001] The present invention relates to the technical field of electrode conductivity measurement, and more specifically to a conductivity detection method and system for an ultra-thin graphene LED electrode. Background Art

[0002] As a new type of nanomaterial, graphene has extremely high conductivity and mechanical strength. These properties make it have wide application potential in electronic devices, composite materials and energy storage. However, the conductivity of graphene may be affected by many factors, such as material purity, thickness, preparation process and use environment. Therefore, in order to ensure the performance stability and reliability of graphene LED electrodes in practical applications, it is necessary to accurately test their conductivity. In the LED field, ultra-thin graphene electrodes have many advantages, such as good conductivity, high light transmittance and high mechanical strength. These properties make ultra-thin graphene electrodes one of the key factors to improve the performance of LED devices. However, the conductivity of ultra-thin graphene electrodes may be affected by the preparation process and material properties. Therefore, it is necessary to use a special detection device to evaluate its conductivity to ensure that it meets the needs of practical applications. Therefore, the existence of a conductivity detection device for ultra-thin graphene LED electrodes is extremely necessary.

[0003] Although there are many methods for measuring the conductivity of graphene, such as the four-probe method and the field effect transistor (FET) method, these methods may not fully meet the detection needs of ultra-thin graphene LED electrodes. For example, the four-probe method may be limited by the size and shape of the electrode, while the FET method may be affected by the preparation process and measurement environment.

[0004] At present, the commonly used ultra-thin graphene LED electrode conductivity detection device often uses an ammeter for measurement during inspection, which requires professional operation. It is also necessary to estimate the current generated in advance and select a suitable ammeter. The wrong choice will damage the ammeter and cause unnecessary losses. In serious cases, it may even damage the circuit and affect the experimental operation process. Summary of the invention

[0005] In order to overcome the above-mentioned defects of the prior art, the present invention provides a method and system for detecting the conductivity of an ultra-thin graphene LED electrode to solve the problems existing in the above-mentioned background technology.

[0036] The cleaning component 5 includes a dual-axis permanent magnet synchronous motor 501, the shaft key of the dual-axis permanent magnet synchronous motor 501 close to the conductive solution box 4 is connected to a driving wheel 502, the two sides of the driving wheel 502 are meshedly connected to driven wheels 503, the center key of the driven wheel 503 is connected to a screw 504, the screw 504 is rotatably sealed and connected to the conductive solution box 4, the center of the screw 504 is spirally connected to a brush 505, the brush 505 is located inside the conductive solution box 4, the bottom of the brush 505 is provided with bristles 5054, and the bristles 5054 are in contact with the bottom of the conductive solution box 4;

[0037] The measuring assembly 7 includes a cylinder body 701, which is in the shape of a barrel with front and rear openings. The cylinder body 701 is fixedly connected to the rotating body 6. One end of a spring 704 is fixedly connected to the bottom of the cylinder body 701. The other end of the spring 704 is fixedly connected to the piston body 702. The piston body 702 is slidably connected to the cylinder body 701. The bottom size of the piston body 702 is larger than the top opening of the cylinder body 701. The top of the piston body 702 is fixedly connected to a piston head 703. The piston head 703 is slidably connected to the rotating body 6. A displacement sensor 705 is fixedly connected to the inside of the rotating body 6. The displacement sensor 705 is opposite to the piston head 703.

[0038] In this embodiment, it should be specifically explained that the conductive liquid will surge back and forth under the action of the cleaning component 5, but it will not change the conductivity of the conductive liquid. Since the speed of the cleaning component 5 is very slow, the impurities at the bottom of the conductive solution box 4 are turned up to a very small height, which will not change the overall conductivity.

[0039] The main difference between this embodiment and the prior art is that this embodiment utilizes the conductivity of the graphene electrode 9 and the principle that the greater the current, the faster the shaft of the dual-axis permanent magnet synchronous motor 501 rotates, and measures the rotation speed of the shaft of the dual-axis permanent magnet synchronous motor 501 to achieve the measurement of the conductivity of the graphene electrode 9, and utilizes the back-and-forth movement of the bristles 5054 to generate friction, specifically in the cleaning component 5 and the measuring component 7;

[0040] The above structure is the main structure of this embodiment, which solves the problem of using friction to clean the bottom of the conductive solution box 4. The dual-axis permanent magnet synchronous motor 501 is an existing structure. The specific structure and connection method of the dual-axis permanent magnet synchronous motor 501 are not described in detail in this embodiment.

[0041] Reference Figure 4The conductive solution box 4 is fixedly connected to the bottom plate 1, the dual-axis permanent magnet synchronous motor 501 is fixedly connected to the bottom plate 1, the positioning box 8 includes a block 801, a through hole 803 is opened at the bottom of the block 801, a positioning hole 802 is opened at the top of the block 801, and the positioning hole 802 is connected with the through hole 803. The rotating body 6 includes a rotating body 601, and the center of the rotating body 601 near one end of the dual-axis permanent magnet synchronous motor 501 is provided with a motor hole 603, and one side of the motor hole 603 is penetrated with a key slot 602, and the key slot 602 is provided at the bottom of the block 801. The groove 602 is key-connected with the dual-axis permanent magnet synchronous motor 501, a support frame hole 604 is provided at the center of the other end of the rotating body 601, a plurality of measuring holes 605 are provided around the support frame hole 604, the measuring component 7 is located inside the measuring hole 605, and a spiral movably connected with a rotary cover 606 at one end of the rotating body 601 close to the support frame hole 604, the rotary cover 606 is movably connected with a bracket 607 on the side of the rotating body 601 away from the dual-axis permanent magnet synchronous motor 501, and the bracket 607 is fixedly connected to the base plate 1.

[0042] In this embodiment, it is necessary to specifically explain that: the dual-axis permanent magnet synchronous motor 501 rotates the rotating body 601 through the keyway 602 and the motor hole 603 to generate centrifugal force. When the graphene electrode 9 is placed inside the positioning hole 802, the conductive solution will make the graphene electrode 9 float, but the height of the conductive solution of the graphene electrode 9 will not allow the graphene electrode 9 to leave the positioning of the positioning hole 802. When the current starts from the anode wire 3 to the inside of the conductive solution, it will pass through the through hole 803 and then through the graphene electrode 9.

[0043] Reference Figure 6 The brush 505 includes a movable plate 5051, a threaded rod hole 5052 is passed through the side of the movable plate 5051, the threaded rod hole 5052 is rotatably sealed and connected to the screw 504, and a plurality of mounting grooves 5053 are fixedly connected to the bottom of the movable plate 5051, and the interior of the mounting grooves 5053 is fixedly connected to the brush bristles 5054.

[0044] In this embodiment, it should be specifically explained that when the moving plate 5051 moves, the bristles 5054 also move accordingly, and the bristles 5054 rub against the bottom of the conductive solution box 4 to produce a cleaning effect.

[0045] Reference Figure 8 The conductive solution box 4 includes a box body 401, which is a hollow box-shaped box. Two shaft holes 402 are passed through the two ends of the box body 401. A filling port 403 is provided on the top of the box body 401. A transparent liquid level observation tube 404 is provided on one side of the box body 401. A suitable water level line 405 is engraved on the surface of the transparent liquid level observation tube 404. A discharge port 406 is opened on the top of the box body 401.

[0046] In this embodiment, it is necessary to specifically explain that: the conductive solution is slowly injected into the conductive solution box 4 through the injection port 403 to ensure smooth injection of the conductive solution, prevent inaccurate amount of the injected conductive solution, and observe outside the transparent liquid level observation tube 404. When the conductive solution reaches the height of the appropriate water level line 405, the injection of the conductive solution is stopped, and the graphene electrode 9 is placed into the conductive solution box 4 from the mouth of the discharge port 406.

[0047] Working principle of the present invention:

[0048] The main problem solved by this embodiment is: utilizing the conductivity of the graphene electrode 9 and the principle that the greater the current, the faster the shaft of the dual-axis permanent magnet synchronous motor 501 rotates, the conductivity of the graphene electrode 9 is measured by measuring the rotation speed of the shaft of the dual-axis permanent magnet synchronous motor 501, and the back-and-forth movement of the bristles 5054 generates friction, and the friction force is used to clean the bottom of the conductive solution box 4.

[0049] The specific steps are as follows:

[0050] First, the conductive solution is slowly injected into the conductive solution box 4 through the injection port 403 to ensure that the conductive solution is injected smoothly and to prevent the amount of the conductive solution injected from being inaccurate. The conductive solution is observed from the outside of the transparent liquid level observation tube 404. When the conductive solution reaches the height of the appropriate water level line 405, the conductive solution injection is stopped. The graphene electrode 9 is placed into the conductive solution box 4 from the discharge port 406. The graphene electrode 9 will stay in the positioning hole 802. The anode wire 3 is connected between the conductive solution box 4 and the power supply 2, and the cathode wire 10 is connected between the conductive solution box 4 and the dual-axis permanent magnet synchronous motor 501.

[0051] Start the power supply 2, the current flows from the power supply 2 into the conductive solution through the anode wire 3, and then the current passes through the graphene electrode 9 to connect the cathode wire 10, and the cathode wire 10 is connected to the dual-axis permanent magnet synchronous motor 501, so that the circuit where the dual-axis permanent magnet synchronous motor 501 is located is closed, and the dual-axis permanent magnet synchronous motor 501 is powered and rotates;

[0052] The two axes of the dual-axis permanent magnet synchronous motor 501 rotate. When the dual-axis permanent magnet synchronous motor 501 rotates away from the axis of the conductive solution box 4, the rotating body 601 connected to the shaft key of the dual-axis permanent magnet synchronous motor 501 is driven to rotate. The rotation of the rotating body 601 generates centrifugal force inside the rotating body 601. The generated centrifugal force causes the piston body 702 and the piston head 703 to move outside the center of the rotating body 601. At this time, the spring 704 is deformed, and the generated deformation force prevents the piston body 702 and the piston head 703 from moving outward. The piston body 702 and the piston head 703 move toward the displacement sensor 705 under the guidance of the measuring hole 605, and the deformation of the spring 704 gradually increases, and the deformation force generated gradually increases. When the deformation force of the spring 704 is the same as the centrifugal force generated, the piston body 702 and the piston head 703 stop moving. At this time, the displacement sensor 705 senses that the distance between the piston head 703 and the displacement sensor 705 remains unchanged. The distance at this time is recorded. At this time, the conductive performance of the graphene electrode 9 can be inferred;

[0053] When the dual-axis permanent magnet synchronous motor 501 rotates close to the axis of the conductive solution box 4, it drives the driving wheel 502 connected to the axis key of the dual-axis permanent magnet synchronous motor 501 to rotate, and the driving wheel 502 drives the driven wheel 503 meshing with it to rotate, and the driven wheel 503 drives the screw 504 to rotate, and the screw 504 drives the brush 505 connected to the screw 504 in a spiral transmission to perform a slow linear motion, and the bristles 5054 rub against the bottom of the conductive solution box 4, so that the impurities at the bottom of the conductive solution box 4 are moved and cleaned. Since the speed of the brush 505 is slow, the impurities at the bottom of the conductive solution box 4 will not float to a high place. When the brush 505 moves to the other end, the axis of the dual-axis permanent magnet synchronous motor 501 is reversed under the action of the controller, and the brush 505 changes direction and moves;

[0054] After the conductivity measurement of the graphene electrode 9 is completed, the power supply 2 is turned off, the drain port at the bottom of the conductive solution box 4 is opened, and the conductive solution and the impurities therein are discharged. Since the impurities leave the bottom of the conductive solution box 4 under the brushing of the brush 505, the impurities are also discharged together with the conductive solution.

[0055] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
