[0037] Description: Figure 3 It is the top view after hiding the top cover of the container.

[0038] Reference Figures 1-6 The present invention provides a device for detecting the thermal insulation performance of a thermal insulation sheet with high precision, comprising:

[0039] A container 100 has a containing space. A partition 200 is located in the containing space and divides the containing space into a first space 101 and a second space 102. A first moving part 300 is used to drive the partition 200 to move so that the first space 101 and the second space 102 are connected or separated.

[0040] A heating unit 400 is disposed in the first space 101 or the second space 102 for heating the thermal insulation sheet; initially, the heating unit 400 may be located in the first space 101 .

[0041] a second moving part 500, when the first space 101 and the second space 102 are connected, the second moving part 500 drives the heating part 400 to move back and forth in the first space 101 and the second space 102; and a detection part 600, at least part of which is located in the first space 101 or the second space 102, for detecting the thermal insulation performance of the thermal insulation sheet. A rack J can be set in the second space 102 to facilitate the installation of the detection part 600 and other components.

[0042] The heating part 400 is heated to a temperature of several hundred to several thousand degrees. When a certain temperature is reached, the first moving part 300 is used to drive the isolation member 200 to move, and at this time, the first space 101 and the second space 102 are connected.

[0043] The second moving part 500 is used to drive the heating part 400 into the second space 102. Then, the heat insulating sheet is placed on the heating part 400, and the temperature of the side of the heat insulating sheet G away from the heating part 400 is detected by the detection part 600 to detect the heat insulating performance of the heat insulating sheet G.

[0044] If all the steps are performed in the first space 101, the temperature in the first space 101 is high during the heating of the heating unit 400. If the temperature of the heat insulation sheet is detected in the first space 101, the high temperature of the air in the first space 101 affects the upper surface of the heat insulation sheet, causing detection errors.

[0045] In this embodiment, by providing a separator, a first space 101 and a second space 102 are formed. Although the air temperature in the first space 101 is relatively high when the heating part 400 is heated, by allowing the heating part 400 to enter the second space 102 for detection, the temperature change in the second space 102 is small and basically remains at room temperature. Thus, when the temperature of the upper surface of the heat insulation sheet G is detected, the air in the second space 102 has little influence, the detection accuracy is high, and the detection effect is effectively guaranteed.

[0046] As a further improvement of the above embodiment, in one embodiment, the first moving part 300 includes:

[0047] A first guide rail 301 arranged in the accommodation space, which can be arranged vertically. Wherein, the separator 200 is movably connected to the first guide rail 301; a first cylinder 302, the output end of which is connected to the separator 200.

[0048] When needed, use the first cylinder 302 to drive the separator 200 to rise, so that the first space 101 communicates with the second space 102, facilitating the heating part 400 to enter the second space 102. After the detection is completed, return to the first space 101. Then, drive the separator 200 to descend to separate the first space and the second space, facilitating subsequent detection.

[0049] As a further improvement of the above embodiment, in one embodiment, the second moving part 500 includes:

[0050] A second guide rail 501 arranged in the accommodation space, which can be arranged horizontally and is arranged in the direction from the first space 101 to the second space 102; a moving member 502 movably connected to the second guide rail 501; wherein, the heating part 400 is arranged on the moving member 502; a second cylinder, the output end of which is connected to the moving member 502. The second cylinder is not shown in the figure.

[0051] Use the second cylinder to drive the moving member 502 to move back and forth along the second guide rail 501, driving the heating part 400 to enter the second space 102 or return to the first space 101.

[0052] As a further improvement of the above embodiment, in one embodiment, a receiving groove 5021 for receiving the heating part 400 is provided on the moving member 502 to prevent the heating part 400 from slipping.

[0053] As a further improvement of the above embodiment, in one embodiment, a heat insulation pad is provided in the receiving groove 5021. Since the temperature of the heating part 400 is relatively high, it is prevented from being conducted to the moving member 502, the second guide rail 501, etc.

[0054] As a further improvement of the above embodiments, in one embodiment, the heating unit 400 includes:

[0055] A heating block 401 is placed in the accommodation groove 5021. A plurality of mounting holes are provided on the heating block 401; a plurality of heating tubes 402 are detachably connected to the plurality of mounting holes. The heating block 401 is heated by the heating tubes 402. When the heating tubes 402 are damaged, they are convenient to replace.

[0056] As a further improvement of the above embodiments, in one embodiment, the detection unit 600 includes:

[0057] A pressing block 601 is arranged in the first space 101 or the second space 102; a third air cylinder 602, whose output end is connected to the pressing block 601 to drive the pressing block 601 to approach or move away from the heating block 401; the output end of the third air cylinder can be located in the second space, and the end far from the output end can be located outside the container; a temperature detector 603 is used to detect the temperature on the side of the heat insulation sheet away from the heating block 401. A sliding rod H can be vertically arranged on the frame J, and the sliding rod H is slidably connected to the frame J. The pressing block 601 is connected to the sliding rod H to ensure the stable lifting of the pressing block 601. The pressing block is detachably connected to the output end of the third air cylinder.

[0058] When the heating block 401 moves below the pressing block 601, place the heat insulation sheet on the heating block 401. Use the third air cylinder 602 to drive the pressing block 601 to descend and tightly press the heat insulation sheet. When the heat insulation sheet is under high temperature and high pressure, use the temperature detector 603 to detect the stability of the upper surface of the heat insulation sheet G, and detect the heat insulation performance of the heat insulation sheet, with high accuracy and ideal effect.

[0059] After the detection is completed, let the pressing block 601 rise and remove the heat insulation sheet.

[0060] As a further improvement of the above embodiments, in one embodiment, the detection unit 600 further includes two clamping jaws 604. The two clamping jaws 604 are symmetrical. The two clamping jaws 604 are located in the accommodation space. The bottom ends of the two clamping jaws 604 are located below the pressing block 601. The top ends of the two clamping jaws 604 are connected to the container 100. The two clamping jaws 604 are made of deformable materials; wherein, the heat insulation sheet is placed at the bottom ends of the two clamping jaws 604.

[0061] When the heating block 401 is placed below the pressing block 601 and the pressing block 601 descends and contacts the heat insulation sheet to drive the heat insulation sheet to descend until the heat insulation sheet is located on the heating block 401.

[0062] The jaw 604 of this embodiment is ingeniously designed and does not require an additional mechanism or manual placement of the heat insulation sheet. After processing is completed, the pressing block 601 rises, and under the action of the elastic force of the jaw 604, it drives the heat insulation sheet to rise and separate from the heating block 401. It has a high degree of intelligence and high efficiency.

[0063] As a further improvement of the above embodiment, in one implementation, the lower parts of the two jaws 604 are inclined towards each other, and the bottom ends of the two jaws 604 are bent and extended towards each other. This facilitates the placement of the heat insulation sheet.

[0064] As a further improvement of the above embodiment, in one implementation, the container 100 is provided with an openable door 103. This is convenient for installing components and for putting in and taking out the heat insulation sheet.

[0065] It can be understood that the pressing block 601 can be freely disassembled and installed at the installation part at the lower end of the third cylinder 602, that is, the lower end of the third cylinder 602 is designed as a detachable slot structure for the pressing block 601 (not shown in the figure), and the slot structure can be compatible with various forms of metal / different material pressing blocks / batteries / test simulation objects, etc.

[0066] The above is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present invention, according to the technical solution and inventive concept of the present invention, making equivalent replacements or changes should be covered within the protection scope of the present invention.
