Description

Technical Field

[0001] This utility model relates to the field of material oxidation testing technology, and specifically to a carbon material oxidation testing system. Background Technology

[0002] Oxidation treatment, as a key process in the preparation and application of carbon materials, can improve material properties. Taking carbon fiber as an example, in its preparation process, carbon fiber precursors need to undergo heat treatment steps such as pre-oxidation, carbonization, and graphitization. Among these, oxidation treatment is a crucial intermediate step to ensure the final performance of carbon fiber. The oxidation process causes molecular structure rearrangement, cross-linking, and dehydrogenation reactions in the carbon fiber precursors under certain temperature and atmosphere conditions, forming a thermally stable ladder-like structure to prevent undesirable phenomena such as melting and breakage during the subsequent high-temperature carbonization stage.

[0003] To ensure the effectiveness and controllability of the oxidation process, corresponding carbon material oxidation tests are usually required. Existing testing techniques mainly examine the degree of oxidation and performance changes of carbon materials under different conditions by adjusting parameters such as current or voltage in the electrolytic cell. However, since the distance between the anode and cathode is mostly fixed, it is impossible to dynamically adjust the distance between the electrodes during the test, resulting in a relatively simple testing method and making it difficult to systematically study the influence of the variable of "electrode spacing" on the oxidation effect of carbon materials. Utility Model Content

[0004] The purpose of this invention is to overcome the aforementioned problems existing in the prior art.

[0005] To achieve the above objectives, this utility model provides a carbon material oxidation testing system, including an electrolytic cell, an electrode plate, and a lifting unit. The electrolytic cell contains a wire harness to be oxidized, connected to the anode of an external power source. The wire harness includes a section to be oxidized that is immersed in the electrolyte within the electrolytic cell and extends horizontally. The electrode plate is positioned below and parallel to the section to be oxidized. The electrode plate has a terminal post whose end is connected to the cathode of the power source, and the end of the terminal post always extends beyond the surface of the electrolyte. The lifting unit is configured to drive the electrode plate to reciprocate vertically to adjust the distance between the wire harness and the electrode plate.

[0006] Optionally, the lifting unit includes a support frame disposed in the electrolytic cell, a guide rail disposed on the support frame, a placement plate slidably disposed on the guide rail, and a transmission mechanism symmetrically connected to both sides of the placement plate. The guide rail extends in a vertical direction, and the transmission mechanism is configured to drive the placement plate to move along the extension direction of the guide rail. The electrode plate is fixedly connected to the placement plate.

[0007] Optionally, the transmission mechanism includes a pair of transmission gears rotatably mounted on the support frame and spaced apart from each other in the vertical direction, a transmission chain tensioned by the transmission gears, and a rotary motor that drives the transmission gears to rotate. The placement plate is fixed to the transmission chain and can be raised and lowered with the operation of the transmission chain when the transmission gears are driven to rotate by the rotary motor.

[0008] Optionally, the guide rail includes a flat plate disposed on both sides of the support frame and extending in a vertical direction. A rotating frame is connected to the plate, and a set of moving wheels is connected to the rotating frame. The set of moving wheels is configured to clamp the plate and slide along the extension direction of the plate.

[0009] Optionally, the drive wheel assembly includes a first drive wheel and a second drive wheel spaced apart in the horizontal direction, and the minimum distance between the outer circumferential surfaces of the first drive wheel and the second drive wheel is not greater than the thickness of the plate.

[0010] Optionally, an insulating plate is provided between the electrode plate and the placement plate.

[0011] Optionally, the carbon material oxidation testing system also includes a first guide connected to the support frame, the first guide being used to guide the wire harness into the electrolytic cell along a predetermined path and partially form the section to be oxidized immersed in the electrolyte.

[0012] Optionally, the first guide member includes a fixed plate disposed opposite to each other, and a first guide roller and a second guide roller arranged in pairs and spaced apart in the horizontal direction. The two ends of the first guide roller and the second guide roller are respectively connected to the fixed plate. The first guide roller is disposed above the second guide roller, and the second guide roller is disposed between the first guide rollers. The wire harnesses pass over the first guide roller on the side facing the second guide roller and the second guide roller on the side facing the first guide roller, respectively. The second guide roller is configured to be at least partially immersed in the electrolyte so that the wire harness located below it can be completely immersed in the electrolyte.

[0013] Optionally, the carbon material oxidation testing system also includes a water washing tank for cleaning the oxidized wire harness. The water washing tank and the electrolytic cell are arranged horizontally at intervals. A second guide is provided on the water washing tank to guide the oxidized wire harness into the washing liquid in the water washing tank.

[0014] Optionally, the wiring harness is electrically connected to the anode of the power supply via carbon brushes.

[0015] Through the above technical solution, this invention uses a lifting unit to drive the electrode plate to reciprocate vertically, precisely adjusting the distance between the electrode plate and the wire harness. This allows for testing the effect of different electrode spacings on the surface oxidation of the wire harness under constant current or voltage conditions. Therefore, compared to existing oxidation tests, this invention can more comprehensively evaluate key factors in the oxidation process, optimize the oxidation process, and ensure controllable and uniform oxidation effects under different conditions.

[0018] The specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings. It should be understood that the specific embodiments described herein are for illustration and explanation only and are not intended to limit the scope of this utility model.

[0019] refer to Figure 1 and Figure 2 The carbon material oxidation testing system of this invention includes an electrolytic cell 1, an electrode plate 8, and a lifting unit 4. Specifically, the electrolytic cell 1 contains an electrolyte and allows a wire harness 2 connected to the anode of a power supply to pass through the containment space of the electrolytic cell 1, thereby immersing the section 201 of the wire harness 2 to be oxidized in the electrolyte and extending horizontally. The electrode plate 8 is disposed below the section 201 to be oxidized and arranged parallel to the section, and is connected to the cathode of a power supply to energize the electrode plate 8 and the wire harness 2. Specifically, by connecting the two poles of the power supply to the electrode plate 8 and the wire harness 2 respectively, the electrolyte located between the two can directionally transmit current to the section 201 of the wire harness 2 to be oxidized, thereby generating an oxidation reaction to form an oxide film on the section.

[0020] The lifting unit 4 of this invention is configured to drive the electrode plate 8 to move vertically, thereby adjusting the distance between the wire harness 2 and the electrode plate 8. Under the condition of applying a constant current or voltage to the wire harness 2 and the electrode plate 8, the lifting unit 4 can be used to test the effect of different electrode spacings on the oxidation of the wire harness 2 surface and the characteristics of the oxidized wire harness 2. Therefore, compared with existing oxidation testing methods, this invention can more comprehensively and flexibly evaluate key factors in the oxidation process, such as the influence of electrode spacing on the quality, uniformity, reaction rate, degree of oxidation of carbon materials, and characteristics after oxidation. Here, the wire harness 2 can be carbon fiber precursor or other types of carbon materials such as graphene fiber.

[0021] In some embodiments, the lifting unit 4 may include a support frame 401 extending into the electrolytic cell 1, a guide rail 402 disposed on the support frame 401 and extending vertically, a placement plate 403 slidably engaged with the guide rail 402, and a transmission mechanism symmetrically connected to both sides of the placement plate 403 to ensure the stability of the placement plate 403 during the driving lifting process. The electrode plate 8 is fixedly installed on the placement plate 403. The transmission mechanism is configured to drive the placement plate 403 to move along the extension direction of the guide rail 402, thereby driving the electrode plate 8 to rise and fall vertically to adjust the distance between the electrode plate 8 and the wire harness 2, thereby adjusting the spacing between the electrode plate 8 and the wire harness 2. Therefore, this invention can test the degree of oxidation under different electrode spacings under the same current or voltage conditions and perform comparative analysis to determine the optimal electrode spacing.

[0022] The transmission mechanism of this utility model includes a pair of transmission gears 404 rotatably mounted on the support frame 401 and spaced apart from each other in the vertical direction, a transmission chain 405 tensioned by the transmission gears 404, and a rotary motor 406 that drives the transmission wheel to rotate. The aforementioned placement plate 403 is fixed to the transmission belt, and when the rotary motor 406 drives the transmission wheel to rotate, the placement plate 403 can rise and fall with the operation of the transmission belt.

[0023] Specifically, the placement plate 403 is located between the transmission gears 404, and the transmission chain 405 forms a vertically extending transmission segment. The placement plate 403 is fixedly connected to this transmission segment, so that when the transmission chain 405 moves, this transmission segment can drive the placement plate 403 to rise and fall vertically. Furthermore, the rotary motor 406 is connected to the transmission gears 404 via a reducer. The reducer lowers the rotational speed of the gears, thereby improving the lifting accuracy of the transmission chain 405. The rotary motor 406 typically has a high rotational speed, and reducing the speed through the reducer ensures that the operator can stop the lifting action in time when needed, avoiding abnormal test data or missing the optimal electrode pitch range due to excessive raising or lowering. Therefore, by precisely adjusting the distance between the electrode plate 8 and the wire harness 2, this invention not only improves the flexibility and accuracy of the testing process but also provides precise adjustability for the oxidation effect under different process conditions, thus providing an important reference for optimizing the oxidation process in practical applications. Compared to traditional oxidation testing methods, this invention, through dynamic adjustment of the electrode spacing, can comprehensively evaluate the interaction between current, voltage, and electrode spacing, thus providing strong technical support for optimizing electrolytic oxidation processes and improving product quality. Furthermore, this invention is not limited to oxidation testing of wire harness 2; it can also be widely applied to oxidation testing of other materials, promoting process optimization and quality improvement in related fields.

[0024] Furthermore, the placement plate 403 can be... Figure 6 The connector 407 shown is connected to a predetermined position on the drive chain 405. Specifically, refer to... Figure 7The connector frame 407 includes two C-shaped frames 4071 with openings arranged opposite each other in the vertical direction. Each C-shaped frame 4071 has a pin hole on its inner surface for inserting the pin of the transmission chain 405, allowing the C-shaped frame 4071 to embed into the transmission chain 405. Thus, the pins at both ends of the broken section of the transmission chain 405 are inserted into the C-shaped frames 4071, achieving connection of the broken ends through these two C-shaped frames 4071. A connector plate 4072 is provided between the two C-shaped frames 4071, connecting the C-shaped frames 4071 to the placement plate 403, enhancing the connection strength and transmission stability with the transmission chain 405. Specific connection methods can include threaded connections, plug-in connections, or other suitable structures, which will not be elaborated upon here. Furthermore, the connector plate 4072 may have threaded holes, allowing the two C-shaped frames 4071 to be bolted to the connector plate 4072, further improving the connection's firmness and stability.

[0025] Furthermore, guide blocks 411 are arranged vertically at intervals on both sides of the inner surface of the support frame 401 facing the transmission chain 405. Each guide block 411 has a groove for the passage of two parallel transmission segments of the transmission chain 405. By limiting the distance between the two parallel transmission segments, the groove effectively prevents the transmission chain 405 from vibrating during transmission and prevents the placement plate 403 from shifting. Simultaneously, this invention also applies opposing tension forces to the transmission chain 405 by adjusting the distance between the two grooves, further reducing vibration. Specifically, the distance between the grooves can be smaller than the diameter of the transmission gear 404, allowing the transmission chain 405 to remain taut at a predetermined position, thereby ensuring the stability of the transmission process. In this invention, each support frame 401 can have two guide blocks 411 on its inner surface, located near the transmission gear 404, to apply appropriate restraint to the two ends of the transmission chain 405 near the transmission gear 404, ensuring the stability and accuracy of the chain during transmission.

[0026] Furthermore, the guide rail 402 of this invention may include flat plates disposed on both sides of the support frame 401 and extending vertically. A rotating frame 408 is connected to the placement plate 403, and a set of moving wheels is connected to the rotating frame 408. The set of moving wheels is configured to support the flat plate and slides along the extension of the flat plate. It can be understood that the transmission chain 405 described above in this invention is already capable of raising and lowering the placement plate 403. Therefore, the flat plate and the set of moving wheels in this invention are mainly used to improve the stability of the placement plate 403 during the rising process.

[0027] Specifically, the drive wheel assembly includes a first drive wheel 409 and a second drive wheel 410 spaced apart in a horizontal direction. The minimum distance between the outer peripheral surfaces of the first drive wheel 409 and the second drive wheel 410 is not greater than the thickness of the flat plate, so that the outer peripheral surfaces of the first drive wheel 409 and the second drive wheel 410 can clamp the flat plate within them. (Reference) Figure 3 The system comprises four flat plates, four sets of moving wheels, and four rotating frames 408. The rotating frames 408 are positioned at the four corners of the placement plate 403. The moving wheels, connected to the rotating frames 408, clamp onto the corresponding flat plates, thus positioning the four corners of the placement plate 403 and preventing it from shifting during lifting. During the lifting process, the moving wheels ensure the stability of the placement plate 403 through precise clamping and positioning, preventing shifting and uneven lifting. This design allows the placement plate 403 to not only rise and fall stably in the vertical direction but also maintain high-precision positioning during lifting, which is particularly important for applications requiring precise control of lifting height.

[0028] Further, refer to Figure 6 Two first moving wheels 409 are provided, arranged vertically at intervals. A second moving wheel 410 is located between the two first moving wheels 409, forming a triangular structure. (Reference) Figure 4 and Figure 5 The first moving wheel 409, the second moving wheel 410 and the guide rail 402 are shown to cooperate. The present invention improves the stability of the cooperation between the moving wheel group and the guide rail 402 through the three-point clamping design, thereby significantly enhancing the smoothness and accuracy of the lifting process of the placement plate 403, reducing the deviation or vibration that may be caused by poor cooperation, and improving the overall performance of the system.

[0029] Further, refer to Figure 8 The rotating frame 408 includes a first strip plate 4081 for mounting a first moving wheel 409, and a second strip plate 4082 fixedly connected to the first strip plate 4081, which is used to mount a second moving wheel 410. An L-shaped connecting plate 4083 is also connected to the second strip plate 4082. The two surfaces of the connecting plate 4083 are respectively provided with slotted holes extending in the vertical and horizontal directions. Each slotted hole is provided with a corresponding fixing bolt; one fixing bolt is used to fix the connecting plate 4083 to the second strip plate 4082, and the other fixing bolt is used to thread it onto the placement plate 403. When installing the placement plate 403 and the rotating frame 408, the relative position of the placement plate 403 and the rotating frame 408 can be adjusted in their extending directions using the adjustment function of these two slotted holes, thereby facilitating the fixing and adjustment of the placement plate 403.

[0030] In this utility model, reference is made to Figure 2A limiting post 412 is provided on the placement plate 403. Nuts are screwed on both ends of the limiting post 412. The nut at the top of the limiting post 412 is used to fix the electrode plate 8 on the placement plate 403, and the nut at the bottom is used to restrict the vertical upward movement of the limiting post 412, so as to clamp the placement plate 403 between the nut and the placement plate 403, and ensure a stable connection between the electrode plate 8 and the placement plate 403.

[0031] Furthermore, to ensure the safety and normal operation of the system, necessary insulation treatment has been carried out on relevant parts in this utility model. Specifically, an insulating plate 5 is provided between the placement plate 403 and the electrode plate 8, and an insulating gasket is also provided between the nut at the top of the limiting post 412 and the electrode plate 8 to prevent current leakage or unnecessary electrical contact, thereby further improving the stability and safety of the system.

[0032] Furthermore, the electrode plate 8 can be connected to the cathode of the power supply via the electrode post 3. Specifically, the outer circumferential surface of the electrode post 3 is entirely provided with an insulating layer. In addition, the end of the electrode post 3 connected to the cathode of the power supply must always be above the surface of the electrolyte to avoid interfering with the flow of current. The insulating layer on the outer circumferential surface of the electrode post 3 may, but is not limited to, consist of an insulating tape wrapped around the outer circumferential surface of the electrode post 3.

[0033] In some embodiments, the carbon material oxidation testing system further includes a first guide member 6 disposed above the opening of the electrolytic cell 1. The first guide member 6 is used to guide the wire harness 2 into the electrolytic cell 1 along a predetermined path and form the aforementioned section 201 to be oxidized in the electrolyte. Specifically, the first guide member 6 includes a fixed plate 601 disposed opposite to each other, and a first guide roller 602 and a second guide roller 603 disposed in pairs and spaced apart in the horizontal direction. The two ends of the first guide roller 602 and the second guide roller 603 are respectively connected to the fixed plate 601. The connection method can be either rotatable or fixed, which will not be elaborated further here.

[0034] Furthermore, the first guide roller 602 is located above the second guide roller 603, and the second guide roller 603 is disposed between the first guide rollers 602, so as to guide the wire harness 2 to pass around the first guide roller 602 toward the side facing the second guide roller 603, and the second guide roller 603 toward the side facing the first guide roller 602, respectively. The second guide roller 603 is configured to be at least partially immersed in the electrolyte so that the wire harness 2 located below it can be completely immersed in the electrolyte.

[0035] In this invention, the anode of the power supply can contact the outer peripheral surface of the second guide roller 603 through a carbon brush. Therefore, the outer peripheral surface of the second guide roller 603 can be made of a conductive material, while the shaft connecting the second guide roller 603 and the fixing plate 601 is made of an insulating material to prevent current from being transmitted to the fixing frame or other positions, thereby preventing the current in the electrolyte from flowing completely in a directional manner to the section 201 to be oxidized of the wire harness 2.

[0036] In some embodiments, the carbon material oxidation testing system further includes a water washing tank 9 for cleaning the oxidized wire harness 2. The water washing tank 9 and the electrolytic cell 1 are arranged at a distance along the horizontal direction, and a second guide 7 is provided on the water washing tank 9. The second guide 7 is used to guide the oxidized wire harness 2 into the washing liquid of the water washing tank 9.

[0037] Specifically, refer to Figure 2 The second guide member 7 may also include a fixed plate 601 arranged opposite to each other. A third guide roller 701 and a fourth guide roller 702 may be arranged in pairs between the fixed plates 601. The positional relationship between the third and fourth guide rollers 702 is the same as the positional relationship between the first and second guide rollers 603. At the same time, the fourth guide roller 702 is also at least partially immersed in the washing liquid carried in the washing tank 9 so that the oxidized wire harness 2 can be immersed in the washing liquid.

[0038] In some embodiments, reference Figure 1 To facilitate the installation of the fixing plate 601 and the support frame 401, the fixing plate 601 can be directly fastened to the outside of the support frame 401. The outside of the support frame 401 is also provided with a limiting plate 101 supported between the fixing plate 601 and the top surface of the electrolytic cell 1, so as to restrict the fixing plate 601 from sliding downward relative to the support frame 401 under the action of gravity.

[0039] The limiting plate 101 can be connected to the top surface of the electrolytic cell 1 by bolt thread.

[0040] Correspondingly, a limiting plate 101 can also be provided on the top surface of the washing tank 9. The limiting plate 101 is used to fix the second guide 7 above the opening of the washing tank 9. It can be understood that by limiting the support height (its own height) of the limiting plate 101, the distance between the fixing plate 601 and the liquid level in the electrolytic cell 1 or the washing tank 9 can also be limited.

[0041] In this invention, the anode of the power supply can be connected to the wiring harness 2 via a carbon brush. Specifically, the carbon brush can be connected to the portion of the outer peripheral surface of the second guide roller 603 that is exposed above the electrolyte surface. In this case, the outer peripheral surface of the second guide roller 603 can be made of a conductive material, while the shaft connecting the second guide roller 603 to the fixing plate 601 is made of an insulating material to prevent conductivity to the support frame 401 or other structures.

[0042] In this invention, the wire harness can be divided into multiple segments along its extension direction. Different segments are provided with different spacings between the wire harness and the electrode plate, thereby forming oxide layers on the wire harness under different electrode spacing conditions to achieve comparative testing of oxidation effects.

[0043] The preferred embodiments of the present invention have been described in detail above with reference to the accompanying drawings; however, the present invention is not limited thereto. Within the scope of the technical concept of the present invention, various simple modifications can be made to the technical solution of the present invention. To avoid unnecessary repetition, the present invention will not describe the various possible combinations separately. However, these simple modifications and combinations should also be considered as the content disclosed in the present invention and all fall within the protection scope of the present invention.
