DETAILED DESCRIPTION

[0036] The specific embodiments of the present application will be further described in detail below with reference to the drawings and examples. The following examples are used to illustrate the present application, but are not used to limit the scope of the present application.

[0037] A system for quickly detecting the thermal conductivity of vacuum insulated panels, comprising a gantry 9, a suction cup presser 26, a thermal conductivity detector 28, and a constant height lifter 27; the upright column of the gantry 9 is fixedly installed on a horizontal plane, and a group of symmetrical upper notches and middle notches are independently provided at the upper end position and the middle position of the inner side of the upright column, and the internal area of the gantry 9 is sequentially set as a first area 29, a second area 30, and a third area 31; the suction cup presser 26 is fixedly installed at the upper notch position through a moving rod 17 erected between the upright columns and moves among the three areas along the moving rod 17; the thermal conductivity detector 28 is set as a box-shaped moving plate 23 integral structure, both ends of the integral structure are fixedly installed at the position between a pair of middle notches, and moves between the second area 30 and the third area 31; the constant height lifter 27 is fixedly installed on the horizontal plane through a slide rail 25, and a group of constant height lifters 27 are provided in the first area 29, the second area 30, and the third area 31, and can move along the horizontal and vertical planes.

[0038] As one of the specific embodiments of the present application, the slide rail 25 is provided with multiple slide rails, for example, three slide rails, which are fixedly installed at the bottom of the gantry 9.

[0039] Among them, the first area 29 is used for storing vacuum insulated panels with qualified thermal conductivity, the second area 30 is used for storing vacuum insulated panels with unqualified thermal conductivity, and the third area 31 is used for storing vacuum insulated panels to be detected for thermal conductivity.

[0040] The thermal conductivity detector 28 is set as a box-shaped moving plate 23 integral structure, both ends of the integral structure are fixedly installed at the position between a pair of middle notches, and moves between the second area 30 and the third area 31.

[0041] The box-shaped moving plate 23 comprises a detection platform 19, a detection element 20, a spring 21 and a fixed support 22. The detection platform 19 is arranged on the uppermost surface of the box-shaped moving plate 23. The detection element 20 is embedded in the middle of the detection platform 19. The bottom of the detection element 20 is connected to one end of the spring 21. The other end of the spring 21 is fixedly connected to the fixed support 22. The fixed support 22 is fixedly installed inside the box-shaped moving plate 23.

[0042] The vacuum insulation panel to be detected is placed on the surface of the detection platform 19. When the pneumatic actuator cylinder 7 of the suction cup pressurizing machine 26 applies pressure in the vertical direction, the detection element 20 is pressed against the spring 21 below. At the same time, the detection element 20 measures the thermal conductivity of the vacuum insulation panel. The fixed support 22 is a fixed support, and the upper end thereof is connected to the bottom of the spring. Preferably, the fixed support 22 is in the shape of a column or a U.

[0043] The purpose of adding the spring is that the detection probe is a lower type. The spring device is installed to increase the contact area between the VIP and the detection probe. When the VIP contacts the probe, a downward movement is performed to increase the contact area.

[0044] Figure 4 The detection element 20 is a sectional view. As a specific embodiment of the present application, the detection element is preferably a detection probe. The middle structure of the probe is a temperature sensor, and the outer structure is a copper plate. The purpose of arranging the copper plate is that the copper plate has good thermal conductivity and can maximize the temperature around the temperature sensor. When detecting the thermal conductivity, the temperature of the copper plate and the temperature sensor is set to 10-100℃, preferably 20-85℃.

[0045] When the detection probe contacts the vacuum insulation panel VIP, the temperature of the area where the vacuum insulation panel VIP contacts the copper plate is stable, for example, 20-85℃. When the temperature sensor contacts the VIP, the temperature is conducted along the thickness direction of the VIP. At this time, the heat on the temperature sensor decreases. In order to maintain the temperature of the sensor, heating is needed to compensate for the heat. The compensation voltage value is the data to be captured. The compensation voltage value is used to determine the thermal conductivity.

[0046] The vacuum heat insulation plate is placed above the heat conductivity detector for the first time in the application, which makes the contact area between the vacuum heat insulation plate and the detection element larger, reduces the time for manual operation and moving the probe, improves the production efficiency, and increases the contact area and pressure between the probe and the heat insulation material by embedding the detection element in the detection platform, which accelerates the measurement speed, greatly shortens the working time, saves a large amount of labor, and improves the degree of mechanical automation.

[0047] The suction disc presser 26 comprises a push rod 1, a vacuum pump 2, a fixed block 3, a cylinder 4, a laser displacement sensor 5, a fixed plate 6, a pneumatic actuator 7, and a suction disc 8.

[0048] The data access and processing unit is used for accessing the barcode information data of the vacuum heat insulation plate to be detected and processing the heat conductivity of the vacuum heat insulation plate after detection, and is connected to a PC 18 through wired or wireless electrical connection.

[0049] The data access and processing unit adopts existing technologies that can realize data access and processing functions, and only the technologies that can realize this purpose can be used.

[0050] The constant height elevator 27 comprises an upper fixed plate 11, a fixed rod 12, a hydraulic actuator 13, a lower fixed plate 15, a roller 16, and a hydraulic machine 14.

[0051] Also includes laser range finder 10, with hydraulic machine 14, hydraulic cylinder 13 are electrically connected, for verifying the top of the vacuum insulated panel to be detected whether to reach the highest set position or verify the vacuum insulated panel after detection whether to drop to the highest set position allowed. Specific operation, when the top of the vacuum insulated panel to be detected reaches the highest set position, will block the laser emitted by the laser range finder, at this time stop the hydraulic cylinder movement; When the detected vacuum insulated panel is placed, the bottom of the hydraulic cylinder moves to the horizontal plane, reduces the height, reduces the height, determines whether it has dropped to the highest set position allowed by blocking the corresponding laser emitted by the laser range finder, at this time stop the hydraulic cylinder movement. The reason for such setting: the detection area, the vacuum insulated panel height needs to rise, the detection area, the vacuum insulated panel height needs to drop, so the laser range finder is needed to judge the rising and falling height value to ensure the accurate position movement.

[0052] Preferably, a plurality of groups are provided for use with each group of constant height lift 27, in order to realize the stacking of different height vacuum insulated panels, adjust the height of the corresponding constant height lift 27, further, the height of the constant height lift 27 of the vacuum insulated panel to be detected is gradually reduced, and the height of the constant height lift 27 of the vacuum insulated panel after detection is gradually increased, thereby ensuring the normal completion of the work of the suction cup.

[0053] As one of the specific embodiments of the present application, a plurality of constant height lifts 27 can be provided, and the constant height lift 27 is movably installed on the slide rail 25. The constant height lift 27 can move in the vertical direction under the action of the hydraulic machine and the hydraulic cylinder, and can move in the plane of each area along the slide rail.

[0054] Also includes automatic stamping machine 32, which is provided in the first area 29 and fixedly installed on the column of the gantry 9. A guide rail is provided on the column, and the automatic stamping machine 32 moves along the guide rail to automatically stamp the vacuum insulated panel after detection. After the work is completed, it moves in the opposite direction of the guide rail and moves back to the original position.

When measuring the thermal conductivity, when the detection probe contacts the vacuum insulation board, the temperature of the area where the vacuum insulation board contacts the copper plate is stable, the temperature is conducted along the thickness direction of the vacuum insulation board. At this time, the heat on the temperature sensor will decrease. In order to maintain the temperature of the sensor, heating is needed to compensate for the heat. The compensation voltage value is the data to be captured. The compensation voltage value is used to determine the thermal conductivity. (Three) stamping and packaging of qualified vacuum insulation boards The PC processes the measurement data. When the measurement value is not within the set range of qualified values, the vacuum insulation board is unqualified. When the measurement value is within the set range of qualified values, the vacuum insulation board is qualified. When it is qualified, the pneumatic actuator (7) is moved upward, the suction disc (8) grabs the vacuum insulation board and places it on the suction disc press (26) in the first area (29), and the automatic stamping machine (32) continues to stamp the qualified product seal. When it is unqualified, the pneumatic actuator (7) is moved upward, the suction disc (8) grabs the vacuum insulation board and places it on the suction disc press (26) in the second area (30) for subsequent processing as unqualified product. (Four) cyclically repeat the work Repeat steps (one) to (three) to detect the thermal conductivity of the vacuum insulation board to be measured until the detection work is completed.

6. The method of claim 5, wherein: In step (three), after the work of grabbing and moving the vacuum insulation board is completed, the suction disc (8) releases the vacuum insulation board, and the moving rod (17) moves the suction disc press (26) back to the third area (31).
