DETAILED DESCRIPTION

[0018] In order to make the purpose, technical solution and advantages of the present invention more clearly understood, the present invention is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not intended to limit the present invention.

[0019] In order to solve the technical problem that a material testing device lacks the function of simulating a high temperature environment, the present invention provides a material testing device that can simulate a high temperature environment when testing a material.

[0020] It should be noted that the material detection device described in the present invention is used for but not limited to testing the electrical properties of materials. For the sake of convenience, in the present invention, only the material detection device applied to the electrical properties detection of materials is used as an example for explanation. The principles of applying the material detection device to other types of detection are essentially the same as those applied to the electrical properties detection of materials, and are not described in detail here.

[0021] See also Figure 1 , Figure 1 It is a structural schematic diagram of a material detection device in an embodiment of the present invention, the material detection device includes a frame 1, a heating component 2, a driving component 3 and a clamp component 4, the heating component 2 includes a heating furnace 21 and a cooling component 22, a heating channel 21a with at least one end open is formed in the heating furnace 21, the cooling component 22 is arranged on the open side of the heating channel 21a, and is used to absorb heat and cool down the open side of the heating channel 21a; the driving component 3 is connected to the frame 1; the clamp component 4 includes a clamp 41, the clamp 41 is connected to the driving component 3, and can be moved between a first position and a second position under the drive of the driving component 3, wherein, in the first position, the clamp 41 extends into the heating channel 21a, and in the second position, the clamp 41 slides out of the heating channel 21a.

[0022] Specifically, when testing the material to be tested, the material is clamped in the fixture 41, and the drive component 3 is started. The drive component 3 moves the fixture 41 and the material to be tested to the first position. At this time, the fixture 41 drives the material to be tested to extend into the heating channel 21a, and then the heating component 2 is started. The heating furnace 21 heats the fixture 41 and the material to be tested in the heating channel 21a, which can simulate a high-temperature environment to measure the electrical properties of the material to be tested in a high-temperature environment. The electrical parameters such as the dielectric constant and dielectric loss, the Cole-Cole diagram of the impedance spectrum, and the electromechanical coupling coefficient Kp can be measured.

[0023] In the present application, by setting up a driving component 3, the driving component 3 can drive the clamp 41 and the material to be tested to extend into and out of the heating channel 21a through the opening of the heating channel 21a, and there is no need to manually take and place the material to be tested in the heating furnace 21, so that the heating furnace 21 can be set to a higher temperature, and it can avoid the set temperature of the heating furnace 21 being too high to threaten the safety of the staff; at the same time, by setting up a cooling component 22, the cooling component 22 can cool the open end of the heating channel 21a, and can isolate the heat in the heating channel 21a from being conducted outward through the end of the heating channel 21a to the lower part of the clamp 41, thereby avoiding the heat from being conducted outward and causing the internal power circuit and other circuits of the clamp 41 to be damaged by high temperature.

[0024] It should be understood that the cooling element 22 may be an air cooling structure, a water cooling structure, etc. Specifically, Figure 6 and Figure 7 As shown, in one embodiment, the cooling member 22 is formed with an annular cooling channel and a liquid inlet and a liquid outlet connected to the cooling channel, and the cooling channel is arranged around the heating channel 21a.

[0025] In this embodiment, coolant is injected into the cooling channel through the liquid inlet, and the coolant flows in a ring shape along the peripheral wall of the heating channel 21a, which can cool the open end of the heating channel 21a and prevent heat from being conducted outward through the open end of the heating channel 21a. At the same time, the annular flow channel ensures that the coolant can flow evenly around the heating channel 21a, reducing local overheating.

[0026] It should be understood that the heating channel 21a may be open at one end or at both ends. Figure 2 and Figure 3As shown, in one embodiment, both ends of the heating channel 21a are open, and there are two cooling members 22 in the heating component 2, and the two cooling members 22 are respectively arranged at the two open ends of the heating channel 21a; the heating component 2 also includes an exhaust member 23, and the exhaust member 23 includes an end cover 231 and an exhaust pipe 232, the end cover 231 is arranged at the open end of the heating channel 21a, and is arranged at the end of the heating channel 21a away from the clamp 41, the exhaust pipe 232 is arranged on the end cover 231, and is connected to the heating channel 21a, and the inner diameter of the exhaust pipe 232 is smaller than the inner diameter of the heating channel 21a.

[0027] By setting the heating channel 21a with openings at both ends, when the driving component 3 drives the fixture 41 and the material to be tested to extend into the heating channel 21a, the air pressure in the heating channel 21a will change. At the same time, when the material to be tested in the heating channel 21a is tested, the air pressure in the heating channel 21a will change. In this embodiment, by setting the heating channel 21a to be open at both ends, one of the open ends is used for the fixture 41 and the material to be tested to slide in and out, and the other open end is provided with an end cover 231 and an exhaust pipe 232. When the fixture 41 and the material to be tested are inserted into the channel and the temperature in the heating channel 21a changes, the gas in the heating channel 21a can It can interact with the outside air through the exhaust pipe 232 to maintain the balance of the air pressure in the heating channel 21a. At the same time, since the inner diameter of the exhaust pipe 232 is smaller than the inner diameter of the heating channel 21a, the exhaust pipe 232 can not only connect to the atmosphere, but also reduce the outflow of gas in the heating channel 21a, reduce the air entering the heating channel 21a, and reduce the temperature fluctuation caused by air flow in the heating channel 21a; by arranging a cooling component 22 at the other open end of the heating channel 21a, the cooling component 22 can cool down the other end of the heating channel 21a to avoid the temperature at the other end of the heating channel 21a being too high and causing harm to personnel.

[0028] It should be understood that in order to form an annular cooling channel, specifically, Figure 4 and Figure 7 As shown, in one embodiment, the cooling member 22 includes a first sleeve 221, a second sleeve 222, two annular plates 223 and a diverter plate 224. The first sleeve 221 is arranged around the heating channel 21a, and the second sleeve 222 is sleeved on the first sleeve 221. The two annular plates 223 are arranged at both ends of the first sleeve 221 and connect the first sleeve 221 and the second sleeve 222. The first sleeve 221, the second sleeve 222, and the two annular plates 223 together form a cooling channel. The diverter plate 224 is arranged in the cooling channel and connected to the first sleeve 221. The liquid inlet and the liquid outlet are arranged on both sides of the diverter plate 224.

[0029] Specifically, in order to cool the end of the heating channel 21a, in this embodiment, coolant is injected into the cooling channel through the liquid inlet, and a diverter plate 224 is arranged in the cooling channel so that the coolant flows along the circumferential direction of the heating channel 21a and then flows into the drain port and is discharged from the drain port. The diverter plate 224 can block the coolant from flowing directly from the liquid inlet to the drain port, thereby increasing the flow path of the coolant and uniformly cooling the heating channel 21a.

[0030] In order to limit the pressure in the cooling channel, Figure 7 As shown, in one embodiment, there is a gap between the diverter piece 224 and the inner wall of the second sleeve 222 .

[0031] In this embodiment, when the pressure in the cooling channel increases, the pressure of the coolant injected into the cooling channel increases, and the gap between the diverter plate 224 and the inner wall of the second sleeve 222 can guide the coolant with increased pressure to pass directly, and the coolant can flow directly from the liquid inlet to the liquid outlet, which is helpful to relieve the pressure in the cooling channel.

[0032] In order to simulate the test of materials in different atmospheres, Figure 2 , Figure 4 , Figure 6 and Figure 7 As shown, in one embodiment, the heating component 2 also includes an atmosphere part 24, which has an air supply channel connected to the heating channel 21a, and the connection between the air supply channel and the heating channel 21a is located on the side of the cooling part 22 close to the opening of the heating channel 21a.

[0033] By setting the atmosphere piece 24, the gas supply channel in the atmosphere piece 24 can pass gas into the heating channel 21a. According to the required atmosphere, the corresponding gas is passed in to simulate an inert atmosphere, an oxidizing atmosphere, a reducing atmosphere, a vacuum atmosphere, etc.

[0034] It should be understood that the heating furnace 21 can be any furnace body capable of heating the material, for example Figure 2 As shown, in one embodiment, the heating furnace 21 includes a support column 211, a furnace chamber 212, a furnace tube 213, and a heating portion 214. The support column 211 is connected to the frame 1, and the furnace chamber 212 is connected to one end of the support column 211 away from the frame 1. A heating cavity is formed in the furnace chamber 212, and both ends of the heating cavity are open. The furnace tube 213 is arranged in the heating cavity, and both ends extend out of the furnace chamber 212 through the opening. The heating portion 214 is connected to the furnace chamber 212 and at least partially extends to the heating cavity. The cavity in the furnace tube 213 is a heating channel 21a.

[0035] When the material needs to be heated, the material is fed into the furnace tube 213, and the heating unit 214 is started. The heating unit 214 heats the furnace tube 213, and the furnace tube 213 heats the internal material. By setting the furnace tube 213, the cavity inside the furnace tube 213 is used as the heating channel 21a, so that heat can be more concentratedly transferred to the material flowing through the furnace tube 213; the furnace chamber 212 plays the role of heat insulation and heat preservation, reducing the loss of heat to the outside of the furnace chamber 212.

[0036] It should be understood that the heating part 214 can be a tungsten wire, a silicon molybdenum rod, etc.

[0037] It should be understood that if Figure 2 As shown, in one embodiment, the heating furnace 21 further includes a shell 215 , the shell 215 is connected to the support column 211 , the furnace 212 is built in the shell 215 , and is connected to the support column 211 via the shell 215 .

[0038] It should be understood that the cooling element 22 and the atmosphere element 24 can be built into the furnace tube 213, or can be sleeved on the furnace tube 213. Figure 2 and Figure 7 As shown, in one of the embodiments, the cooling member 22 is sleeved on the furnace tube 213, and the two cooling members 22 are arranged at both ends of the furnace tube 213. The first sleeve 221 in the cooling member 22 is sleeved on the furnace tube 213, and the atmosphere member 24 is arranged at one end of the furnace tube 213. The atmosphere member 24 includes an end ring 241 and an air pipe 242. The end ring 241 is arranged at one end of the furnace tube 213 and connected to the outer shell 215. The end ring 241 is radially provided with a through hole. The air pipe 242 is connected to the end ring 241 and is communicated with the through hole. The air pipe 242 and the through hole are combined to form an air supply channel.

[0039] When it is necessary to introduce atmosphere into the furnace tube 213 , the atmosphere is injected into the air pipe 242 or air is extracted outward through the air pipe 242 , and the atmosphere enters the furnace tube 213 , forming a set atmosphere in the furnace tube 213 .

[0040] In order to seal the first sleeve 221 and the furnace tube 213, Figure 4As shown, in one embodiment, an annular cavity is formed between the furnace tube 213 and the first sleeve 221, the inner wall of the end of the first sleeve 221 located in the annular cavity is tapered, the end ring 241 extends into the annular cavity to form a first support ring 243, the first support ring 243 is sleeved on the furnace tube 213, and the end surface of the first support ring 243 away from the end ring 241 is tapered, the atmosphere member 24 further includes a first fixed ring 244, a first sealing ring 245 and a second sealing ring 246, the first fixed ring 244 is arranged between the furnace tube 213 and the first The first fixed ring 244 is provided between the first fixed ring 244 and the first supporting ring 243, and is sleeved on the furnace tube 213. The first sealing ring 245 is provided between the first fixed ring 244 and the first supporting ring 243, and is sleeved on the furnace tube 213. The first sealing ring 245 abuts against the conical surface of the first supporting ring 243 and the conical surface of the first fixed ring 244. The second sealing ring 246 is provided between the first fixed ring 244 and the conical end surface of the annular cavity, and abuts against the conical end surface of the first fixed ring 244 and the conical end surface of the annular cavity.

[0041] By providing the first sealing ring 245 and the second sealing ring 246, the gap between the first sleeve 221 and the furnace tube 213 can be fixed. On the basis of providing the first sealing ring 245 and the second sealing ring 246, a first fixed ring 244 is further provided. The first fixed ring 244 can squeeze the first sealing ring 245 and the second sealing ring 246 during the process of sliding into the annular cavity, so that the first sealing ring 245 is deformed and fits the conical end faces of the first fixed ring 244 and the first support ring 243, so that the second sealing ring 246 is deformed and fits the conical end faces of the annular cavity and the first fixed ring 244, and the first sealing ring 245 and the second sealing ring 246 are closely attached to the outer wall of the furnace tube 213. The first fixed ring 244 realizes the close fit between the first sealing ring 245 and the second sealing ring 246 and the outer wall of the furnace tube 213, thereby avoiding looseness and gaps between the first sealing ring 245 and the second sealing ring 246 and the outer wall of the furnace tube 213.

[0042] like Figure 8 and Fig. 9 As shown, in one embodiment, the clamp 41 includes a base 411, two upper electrodes 412, and two lower electrodes 413. The two upper electrodes 412 are slidably connected to the base 411 and can slide toward and away from each other. The two lower electrodes 413 are slidably connected to the base 411 along the guide of the heating channel 21a.

[0043] By setting two upper electrodes 412, the two upper electrodes 412 can slide in directions close to and away from each other, and can clamp materials to be tested of different sizes. By using two lower electrodes 413 that can slide along the guide of the heating channel 21a, the lower electrode 413 can abut against materials to be tested of different heights. After the upper electrode 412 and the lower electrode 413 slide, they can be fixed by additional structures or springs; the two upper electrodes 412 and the two lower electrodes 413 are used for external testing equipment to detect the electrical properties of the materials to be tested.

[0044] In the process of the driving assembly 3 driving the clamp 41 to extend into and out of the furnace tube 213, in order to prevent heat from being conducted outward through the open end of the furnace tube 213, for this purpose, Figure 8 and Fig. 9 As shown, in one of the embodiments, the clamp assembly 4 also includes a thermal insulation component 42, which is connected to the base 411 and is sleeved on two upper electrodes 412 and two lower electrodes 413. When the thermal insulation component 42 is in the first position, the thermal insulation component 42 blocks an open end of the heating channel 21a.

[0045] In this embodiment, by providing a thermal insulation component 42, when the two upper electrodes 412 and the two lower electrodes 413 slide into the furnace tube 213, the thermal insulation component 42 abuts against the end ring 241 and blocks the open end of the bottom of the furnace tube 213, which can play a role in heat preservation and isolation of heat conduction to the outside, thereby preventing the electronic equipment in the base 411 from being damaged due to high temperature.

[0046] It should be understood that the thermal insulation component 42 can be made of a material that can play a thermal insulation role, such as ceramic fiber, rock wool, and calcium carbonate; the shape of the thermal insulation component 42 matches the shape of the inner wall of the furnace tube 213.

[0047] It should be understood that the thermal insulation member 42 may be directly connected to the support platform 411 or indirectly connected to the support platform 411. Figure 8 and Fig. 9 As shown, in one embodiment, the clamp assembly 4 further includes a support member 43 , and the support member 43 is disposed between the thermal insulation member 42 and the support platform 411 , and the thermal insulation member 42 is connected to the support platform 411 via the support member 43 .

[0048] In this embodiment, a gap is set between the thermal insulation component 42 and the base 411. The gap can prevent heat from being directly transferred to the base 411 through the thermal insulation component 42, and can play a role in protecting the electronic components in the base 411. At the same time, by setting the support component 43, the connection between the base 411 and the thermal insulation component 42 can be achieved.

[0049] Specifically, the support member 43 may be a support column 211, a support bar, a support rod, etc. The number of the support members 43 may be one, two, or more. Specifically, Figure 8 and Fig. 9 As shown, in one embodiment, there are multiple support members 43, and the multiple support members 43 are distributed at intervals along the circumference of the thermal insulation member 42.

[0050] like Figure 8 and Fig. 9 As shown, in one of the embodiments, the thermal insulation component 42 has two slide grooves, which are arranged along the direction of the axis of the vertical heating channel 21a. The clamp 41 also includes two ceramic columns 414, which are slidably arranged in the two slide grooves and slidably connected to the base 411. The two upper electrodes 412 are respectively connected to the two ceramic columns 414.

[0051] By setting two ceramic columns 414, a sliding connection between the two upper electrodes 412 and the base 411 is achieved, and the ceramic columns 414 can support the two upper electrodes 412. At the same time, the ceramic columns 414 can withstand high temperatures and are poor conductors of heat, which can prevent heat from being transferred to the base 411 through the ceramic columns 414.

[0052] In order to fix and support the material to be tested, specifically, Figure 8 and Fig. 9 As shown, in one embodiment, the fixture 41 also includes a support tube 415 and a ceramic cover 416, the support tube 415 is connected to the base 411, the ceramic cover 416 is connected to the side of the support tube 415 away from the base 411, the ceramic cover 416 defines a channel for two lower electrodes 413 to slide up and down, the two lower electrodes 413 are slidably arranged in the channel, and the two upper electrodes 412 are arranged on both sides of the ceramic cover 416.

[0053] In this embodiment, by providing a ceramic cover 416 , the ceramic cover 416 can provide a support platform for the material to be tested. At the same time, the ceramic cover 416 is resistant to high temperatures and can support the material to be tested in a high temperature environment.

[0054] It should be understood that the support 411 and the driving assembly 3 can be fixedly connected or detachably connected. Figure 5 As shown, in one embodiment, the support platform 411 is detachably connected to the driving assembly 3.

[0055] In this embodiment, the support platform 411 is detachably connected to the driving assembly 3. When different electrical properties of the material need to be tested, the corresponding fixture 41 and the test device can be quickly replaced by disassembling the support platform 411.

[0056] It should be understood that the support 411 and the driving assembly 3 can be detachably connected by bolts, screws, buckles, etc. Specifically, Figure 5 As shown, in one embodiment, the support platform 411 is formed with a slot, and the driving component 3 is formed with a block 324 relative to the slot, and the block 324 is engaged with the slot.

[0057] In this embodiment, the detachable connection between the support platform 411 and the driving assembly 3 can be achieved by engaging the engaging block 324 with the engaging slot.

[0058] It should be understood that the driving component 3 can be a multi-axis mechanical arm, a cylinder, a hydraulic cylinder, an electric push rod, etc. Specifically, Figure 5 and Figure 6 As shown, in one embodiment, the driving assembly 3 includes a linear driving member 31 and a connecting member 32, the linear driving member 31 has a fixed end and a movable end capable of moving axially along the heating channel 21a, the fixed end of the linear driving member 31 is connected to the frame 1, the connecting member 32 includes an end plate 321, a supporting portion 322 and an elastic portion 323, the end plate 321 is connected to the movable end of the linear driving member 31, the end plate 321 is formed with a clamping block 324, the supporting portion 322 is slidably sleeved on the end plate 321 along the axial direction of the heating channel 21a, the supporting portion 322 is connected to the clamp 41, and the elastic portion 323 connects the end plate 321 and the supporting portion 322.
