Description

Technical Field

[0001] The utility model discloses a conductive stability detection device for a graphene flexible heating cloth polyester heating wire, and relates to the technical field of heating wire conductivity detection. Background Art

[0002] Graphene is an allotrope of carbon, with carbon atoms arranged in sp 2 Hybrid bonding forms a single-layer hexagonal honeycomb lattice graphene. The arrangement of carbon atoms inside graphene is the same as that of graphite single atomic layer, with sp2 hybrid orbital bonding, and has the following characteristics: carbon atoms have 4 valence electrons, 3 of which generate sp2 bonds, that is, each carbon atom contributes an unbonded electron located in the pz orbital, and the pz orbital of the neighboring atom is perpendicular to the plane to form a π bond, and the newly formed π bond is half-filled. Studies have confirmed that the coordination number of carbon atoms in graphene is 3, the bond length between each two adjacent carbon atoms is 1.42×10-10 meters, and the angle between bonds is 120°. In addition to the σ bond and other carbon atoms linked to the honeycomb layered structure of the hexagonal ring, the pz orbital of each carbon atom perpendicular to the layer plane can form a large multi-atomic π bond (similar to the benzene ring) that runs through the entire layer, and thus has excellent conductive and optical properties. Therefore, the heating wire prepared using graphene has good conductivity.

[0003] Chinese Patent Publication No.: CN 210381336 U published "A Graphene Polymer Nano Energy Heating Wire", which includes a heating core and a protective layer. The heating core is formed by three-dimensional weaving of a number of polymer nano energy wires. The protective layer includes an insulating layer and a waterproof layer arranged in sequence from the inside to the outside, and tightly covers the heating core.

[0004] The above-mentioned graphene polymer nano energy heating wire has good integrity and overcomes the defects of other weaving methods such as low strength, easy delamination, and the need for stitching and mechanical processing. The heating wire formed by three-dimensional weaving has strong continuity, excellent softness, resistance to bending, not easy to break, and long service life.

[0005] The heating wire needs to be tested for conductivity before being used for weaving to ensure that each thermal wire can conduct electricity stably.

The utility model provides a graphene electric heating film heating effect detection device, which starts the device by switching on and off to heat the graphene heating film, and then the graphene heating film emits infrared thermal radiation, and then the infrared thermal radiation passes through the convex lens, the first concave lens, the chamfered mirror, the filter, the second concave lens and the detector in sequence, and then the detector converts the infrared thermal radiation into an electrical signal, and finally its value will be displayed on the display screen, thus completing the use process of a graphene electric heating film heating effect detection device.

[0007] However, because the thermal wire is often bent, curled and folded, these operations will affect the heating wire, and existing testing equipment is unable to test the conductive performance of the heating wire body during the bending process. Utility Model Content

[0034] The conductive mechanism 2 includes a fixed wire clamp 201 and a sliding wire clamp 202. The fixed wire clamp 201 is fixedly connected to one end of the top of the support frame 102. The bottom of the sliding wire clamp 202 extends to the inside of the limiting groove 104 and is penetrated by the limiting slide rod 105. The elastic member 106 applies pressure to the sliding wire clamp 202 to move the sliding wire clamp 202 toward the edge of the support frame 102.

[0035] The opposite surfaces of the fixed wire clamp 201 and the sliding wire clamp 202 are both provided with a plurality of independent clamping openings, the inside of the clamping openings is provided with a metal sheet, the metal sheet is overlapped with the end of the heating wire body 4, the side of the fixed wire clamp 201 is fixedly connected with a power line terminal 203, and the side of the sliding wire clamp 202 is provided with a test line terminal 204, the power line terminal 203 and the test line terminal 204 are one-to-one corresponding to the clamping openings, and the power line terminal 203 and the test line terminal 204 are both fixedly connected with the metal sheet;

[0036] The power supply line terminal 203 is connected to a power source to supply power to the heating wire body 4, and the test line terminal 204 is connected to a device for testing conductivity;

[0037] The bending mechanism 3 includes more than two groups of shaftless cylinders 301 , and a bending rod 302 is fixedly connected between each group of shaftless cylinders 301 . Driven by the shaftless cylinders 301 , the bending rod 302 floats up and down to bend the heating wire body 4 .

[0038] Through the above technical solution, a fixed wire clamp 201 and a sliding wire clamp 202 are set to clamp the two ends of the heating wire body 4, so that the current passes from the power supply line terminal 203 through the heating wire body 4 and reaches the test line terminal 204, and finally reaches the conductivity detection device to detect the current and voltage changes. During the detection process, the shaftless cylinder 301 drives the bending rod 302 to float up and down to bend the heating wire body 4, so as to detect the conductive performance of the heating wire body 4 during the bending process, thereby achieving the detection of the conductive performance of the heating wire body 4 during the bending process;

[0039] The electrical detection equipment is a device that can monitor current changes, such as a voltmeter, an ammeter, etc., which is connected one by one with a single heating wire body 4 to achieve current testing and data recording.

[0040] Specifically, the bottom bin 101 and the support frame 102 are both made of insulating materials. A cavity is provided inside the bottom bin 101, and a controller of the shaftless cylinder 301 is installed in the cavity.

[0043] Through the above technical solution, the provided extension frame 103 is used to separate the sliding wire clamp 202 and the test wire terminal 204 , so that the test wire terminal 204 does not move with the movement of the sliding wire clamp 202 .

[0044] Specifically, a retractable connecting wire 205 is connected between the sliding wire clamp 202 and the test wire terminal 204 , and the retractable connecting wire 205 is extensible.

[0052] When in use, the two ends of the heating wire body 4 are clamped by setting a fixed wire clamp 201 and a sliding wire clamp 202, so that the current passes through the heating wire body 4 from the power supply line terminal 203 to the test line terminal 204 and finally to the conductivity detection device for current and voltage change detection. During the detection process, the shaftless cylinder 301 drives the bending rod 302 to float up and down to bend the heating wire body 4, so as to detect the conductive performance of the heating wire body 4 during the bending process, thereby achieving the detection of the conductive performance of the heating wire body 4 during the bending process;

[0053] By setting a telescopic connecting wire 205 between the sliding wire clamp 202 and the test wire terminal 204 and making the telescopic connecting wire 205 ductile, when the heating wire body 4 is bent by the bending rod 302, the connection between the sliding wire clamp 202 and the test wire terminal 204 is prevented from being pulled and broken during the movement of the sliding wire clamp 202, thereby achieving the effect of prolonging the service life of the equipment.
