Description

Technical Field

[0001] The present invention relates to the technical field of detection equipment, and particularly to a device for detecting the cutting accuracy of graphene carbon felt. Background Art

[0002] Graphene carbon felt is a porous material formed by subjecting carbon fiber to high-temperature graphitization treatment. Its core component is graphene, which is a single-layer two-dimensional material with a honeycomb-like structure composed of carbon atoms. Due to the excellent electrical, thermal, and mechanical properties of graphene, the performance of graphene carbon felt in these aspects has also been greatly improved. The carbon felt is a network structure formed by the interweaving of a large number of carbon fibers, providing good mechanical strength and high-temperature resistance characteristics. It has high strength, high conductivity, and high-temperature resistance characteristics, and is widely used in fields such as batteries and filter materials.

[0003] When graphene carbon felt is used, it needs to be sheared, and the cutting accuracy directly affects the subsequent processing performance (such as roll forming) and the quality of the end product (such as the thermal insulation material for a single-crystal silicon smelting furnace). Traditional cutting machines only complete the cutting process, and manual rolling and sewing are required, resulting in a complex process, low efficiency, and a lack of real-time accuracy detection, which is prone to introducing errors.

[0004] To solve the above problems, we have proposed a device for detecting the cutting accuracy of graphene carbon felt. Summary of the Invention

The light-emitting ring provides a light source, and the driving motor two drives the probe to rotate to detect the light transmittance of the edge of the detection sample.

[0007] In the above device for detecting the cutting accuracy of graphene carbon felt, the conveying area includes conveying rollers provided on the machine tool. A reduction motor is provided on the machine tool. The output end of the reduction motor is fixedly connected to the end of the conveying roller.

[0008] In the above graphene carbon felt cutting precision detection device, a bottom plate is fixed on the machine tool, and a first oil cylinder is fixedly connected to the bottom plate. The driving end of the first oil cylinder is vertically arranged and fixedly connected to a first driving motor. The driving end of the first driving motor is fixedly connected to a U-shaped rod, and the turntable is fixed on the U-shaped rod. The negative pressure mechanism includes an air pump, and the air pump is fixed at the top of the driving end of the first driving motor. A negative pressure suction cup is fixed at the center of the lower side wall of the turntable. An air extraction joint is connected between the air pump and the negative pressure suction cup, and a plurality of suction ports communicating with the negative pressure suction cup are formed on the surface of the turntable.

[0009] In the above graphene carbon felt cutting precision detection device, a right-angle support plate is fixedly connected to the outer wall of the first driving motor, and a power supply copper ring is fixedly connected to the end of the right-angle support plate. A carbon brush in contact with the inner wall of the power supply copper ring is fixedly installed on the outer wall of the U-shaped rod, and the carbon brush is connected to the air pump through a wire.

[0010] In the above graphene carbon felt cutting precision detection device, the light-emitting ring includes a transparent PVC round cover arranged in a circular shape and a plurality of supplementary light sources evenly distributed inside the transparent PVC round cover.

[0011] In the above graphene carbon felt cutting precision detection device, a limiting component is further arranged on the upper side wall of the machine tool. The limiting component includes an electric push rod fixed on the upper side wall of the machine tool, and a limiting member is fixedly connected to the driving end of the electric push rod. The limiting member includes an arc plate and limiting arms fixed at both ends of the arc plate.

[0012] In the above graphene carbon felt cutting precision detection device, the distance between the two limiting arms gradually decreases from front to back, and the distance between the ends of the two limiting arms is equal to the diameter of the arc plate.

[0013] In the above graphene carbon felt cutting precision detection device, a smoothness test component is arranged on the arc plate.

[0016] Compared with the existing technology, the advantages of this graphene carbon felt cutting precision detection device are as follows: A limiting member is provided. The conveying roller drives the detection sample to move forward, and the distance between the limiting arms gradually decreases to a distance equal to the diameter of the detection sample, which has the effect of centering the detection sample, enabling the detection sample to gradually center during movement until it accurately moves onto the turntable. A detection cover is provided. After the detection sample moves onto the turntable, the detection cover moves down to cover the detection sample. The light emitted by the supplementary light source shines on the edge of the detection sample. If the edge is not cut completely, the edge of the detection sample will transmit light, and the transmitted light is received by the probe of the light transmittance detector. If the edge is cut completely, there will be no light transmission or less light transmission. A smoothness test component is provided. The driving motor 1 drives the turntable and the adsorbed detection sample to rotate. The edge of the detection sample comes into contact with the contact wheel. When the edge of the detection sample is not smooth, the friction force at the contact point with the contact wheel is relatively large, and there is a thrust force that drives the contact wheel and the flat plate to rotate, causing the contact wheel to rotate. The change in the pressure coefficient of the pressure sensor is relatively large, indicating that the edge of the detection sample is less smooth. If there is no change or the change is small, it indicates that the edge of the detection sample is smooth. In summary, the present invention detects the light transmittance of the edge of the detection sample to achieve the detection of the cutting integrity of the detection sample. A high integrity results in low light transmittance. The smoothness test component is used to complete the detection of the smoothness of the edge of the detection sample, achieving the detection of the cutting smoothness, and realizing the rapid detection of the cutting completion degree and integrity.

Specific embodiments

[0019] The following embodiments are for illustrative purposes only and are not intended to limit the scope of the present invention.

[0020] Referring to Figures 1-5 , a graphene carbon felt cutting accuracy detection device, including a machine tool 1, a conveying area and a detection area are arranged on the machine tool 1. The conveying area includes a conveying roller 2 arranged on the machine tool 1. A reduction motor is arranged on the machine tool 1, and the output end of the reduction motor is fixedly connected to the end of the conveying roller 2. A test sample 3 is conveyed on the conveying area. The test sample 3 is a sample cut out for testing. The conveying roller 2 is driven by the reduction motor to rotate, and then the test sample 3 is driven to move forward. A limiting component is also arranged on the upper side wall of the machine tool 1. The limiting component includes an electric push rod 4 fixed on the upper side wall of the machine tool 1. The driving end of the electric push rod 4 is fixedly connected with a limiting part 5. The limiting part 5 includes an arc plate and limiting arms fixed at both ends of the arc plate. The distance between the two limiting arms gradually decreases from front to back, and the distance between the ends of the two limiting arms is equal to the diameter of the arc plate. The conveying roller 2 drives the test sample 3 to move forward, and the distance between the limiting arms gradually decreases to the same distance as the diameter of the test sample 3, which has the effect of centering the test sample 3, so that the test sample 3 can be centered slowly during the movement until it moves onto the turntable 10.

[0021] The detection area includes a rotatable turntable 10. A negative pressure mechanism for adsorbing the test sample 3 is arranged on the turntable 10. A bottom plate 6 is fixed on the machine tool 1. A first oil cylinder 7 is fixedly connected to the bottom plate 6. The driving end of the first oil cylinder 7 is vertically arranged and fixedly connected with a first driving motor 8. The driving end of the first driving motor 8 is fixedly connected with a U-shaped rod 9. The turntable 10 is fixed on the U-shaped rod 9. The negative pressure mechanism includes an air pump 12. The air pump 12 is fixed at the top of the driving end of the first driving motor 8. A negative pressure suction cup 13 is fixed at the center of the lower side wall of the turntable 10. An air extraction joint is connected between the air pump 12 and the negative pressure suction cup 13. A plurality of sucking ports 14 communicating with the negative pressure suction cup 13 are opened on the surface of the turntable 10. To ensure that the test sample 3 will not fly out during the subsequent rotation of the turntable 10, the test sample 3 is adsorbed by negative pressure. The air pump 12 is started to extract the air between the negative pressure suction cup 13 and the test sample 3 and the turntable 10, so that negative pressure is generated at the sucking port 14 to suck the test sample 3 tightly.

[0022] A right-angled support plate 15 is fixedly connected to the outer wall of the first driving motor 8. A power supply copper ring 16 is fixedly connected to the end of the right-angled support plate 15. A carbon brush 17 in contact with the inner wall of the power supply copper ring 16 is fixedly installed on the outer wall of the U-shaped rod 9. The carbon brush 17 is connected to the air pump 12 through a wire. The power supply copper ring 16 is connected to an external power source or the mains through a wire. The first driving motor 8 drives the U-shaped rod 9 and the carbon brush 17 to rotate. The current on the power supply copper ring 16 is led out through the carbon brush 17 for the air pump 12 to use, ensuring that the air pump 12 can still continuously work during the rotation of the turntable 10, enabling a continuous negative pressure to be formed at the suction port 14 for adsorbing the test sample 3 and preventing the test sample 3 from falling off.

[0023] A light-emitting ring 11 is fixedly sleeved on the outer wall of the turntable 10. An oil cylinder two is fixed to the outer wall of the machine tool 1. The driving end of the oil cylinder two is fixed with a fixing plate 23. A detection cover 24 is fixed to the end of the fixing plate 23. A second driving motor 25 is arranged in the middle of the detection cover 24. A light transmittance detector 26 and a probe 28 connected to the light transmittance detector 26 are also arranged in the detection cover 24. The driving end of the second driving motor 25 is fixed with a connecting plate 27. The probe 28 is fixedly installed at the end of the connecting plate 27. The light-emitting ring 11 includes a transparent PVC round cover arranged in a circular shape and a plurality of supplementary light sources evenly distributed inside the transparent PVC round cover. After the test sample 3 moves onto the turntable 10, the detection cover 24 moves down to cover the test sample 3. The light emitted by the supplementary light sources shines on the edge of the test sample 3. If the edge is not cut completely, the edge of the test sample 3 will be transparent, and the transmitted light is received by the probe 28 of the light transmittance detector 26. If the edge is cut completely, it is opaque or has little light transmission. After the test sample 3 moves onto the turntable 10, the detection cover 24 moves down to cover the test sample 3. The light-emitting ring 11 provides a light source, and the second driving motor 25 drives the probe 28 to rotate for detecting the light transmittance of the edge of the test sample 3.

[0024] A smoothness test component is provided on the arc plate. The smoothness test component includes a notch formed in the arc plate. A rotating shaft 18 is provided in the notch. A flat plate 20 is fixed to the upper end of the rotating shaft 18. A contact wheel 21 for contacting the test sample 3 is provided in the notch. The end of the flat plate 20 is fixedly connected to the contact wheel 21 through a connecting rod. A pressure sensor 22 is fixed on the outer wall of the arc plate. A return spring 19 is sleeved on the rotating shaft 18. The two ends of the return spring 19 are respectively fixedly connected to the upper side wall of the arc plate and the lower side wall of the flat plate 20. An opening communicating with the notch is formed in the upper side wall of the arc plate. The connecting rod is movably located in the opening. When testing the edge smoothness of the test sample 3, the driving motor 1 is started to drive the turntable 10 and the adsorbed test sample 3 to rotate. The edge of the test sample 3 contacts the contact wheel 21. When the edge of the test sample 3 is not smooth, the friction force at the contact with the contact wheel 21 is relatively large, and there is a thrust force that drives the contact wheel 21 and the flat plate 20 to rotate, causing the contact wheel 21 to rotate. The pressure coefficient of the pressure sensor 22 changes greatly, indicating that the edge of the test sample 3 is less smooth. If there is no change or the change degree is small, it indicates that the edge of the test sample 3 is smooth.

[0025] The inner diameter of the detection cover 24, the diameter of the turntable 10, the diameter of the test sample 3, and the diameter of the arc plate are equal.

[0026] In summary, the detection process of the test sample 3 includes: The edge of the arc plate coincides with the edge of the turntable 10. The conveying roller 2 drives the test sample 3 forward to move onto the turntable 10. The air pump 12 is started to pump out the air between the negative pressure suction cup 13 and the test sample 3 and the turntable 10, so that negative pressure is generated at the suction port 14 to suck the test sample 3 tightly. The driving end of the electric push rod 4 retracts, driving the limiting member 5 to move towards the side of the electric push rod 4 to ensure that the detection cover 24 will not contact the limiting member 5 when it moves down later. The detection cover 24 moves down to cover the test sample 3. The light emitted by the supplementary light source shines on the edge of the test sample. If the edge shearing is incomplete, the edge of the test sample 3 will transmit light, and the transmitted light is received by the probe 28 of the light transmittance detector 26. If the edge shearing is complete, there is no light transmission or less light transmission. After the light transmission detection is completed, the detection cover 24 rises. The driving motor 1 is started to drive the turntable 10 and the adsorbed test sample 3 to rotate. The edge of the test sample 3 contacts the contact wheel 21. When the edge of the test sample 3 is not smooth, the friction force at the contact with the contact wheel 21 is relatively large, and there is a thrust force that drives the contact wheel 21 and the flat plate 20 to rotate, causing the contact wheel 21 to rotate. The pressure coefficient of the pressure sensor 22 changes greatly, indicating that the edge of the test sample 3 is less smooth. If there is no change or the change degree is small, it indicates that the edge of the test sample 3 is smooth.
