Description

Technical Field

[0001] This utility model relates to the field of thermally conductive material compression testing technology, and in particular to a thermally conductive material compression testing device. Background Technology

[0002] Compression testing of elastic thermally conductive materials requires plotting a curve showing the relationship between the material's compressibility and pressure. However, existing compression testing methods primarily utilize thermal conductivity meters and universal testing machines, neither of which can meet the demands of compressing elastic thermally conductive materials. When using a thermal conductivity meter, pressure is continuously applied to the material, and the percentage change in thickness is recorded to obtain accurate data. Furthermore, universal testing machines cannot provide the required pressure (pressure per square meter) to compress the material to a specific amount, making compression testing impossible. Therefore, existing compression testing equipment cannot provide the necessary accurate data, and consequently, cannot provide the OEM's design data on the pressure required to compress the thermally conductive material sheet to a certain percentage and the pressure borne by the screws securing the heat dissipation module. Utility Model Content

[0004] To achieve the above objectives, this utility model discloses a thermally conductive material compression testing device, which includes:

[0005] The test platform is equipped with test positions for placing thermally conductive materials;

[0006] A compression device is provided on the test platform corresponding to the test position. The compression device includes a driver and a lifting component.

The screw is rotatably mounted on the bracket and threadedly connected to the slider through the threaded hole. The drive end of the servo motor is connected to the screw, and the control end of the servo motor is connected to the drive unit. The drive unit is used to control the servo motor to drive the screw to rotate, thereby driving the slider to move the lifting component vertically along the groove.

The controller is used to control the distance by which the driver drives the lifting component to move vertically and to transmit the pressure value read by the data acquisition unit to the display for display.

[0013] This invention features a compression device that works in conjunction with a data acquisition unit to perform compression tests. The compression device is mounted on a test platform and includes a driver and a lifting component. The driver moves the lifting component vertically towards or away from the test position on the test platform where the thermally conductive material is placed. When the lifting component compresses the thermally conductive material in the test position, a pressure sensor mounted on the lifting component detects the magnitude of the force acting on it. The data acquisition unit reads the pressure values ​​detected by the pressure sensor, thereby accurately testing the stable pressure required to compress the thermally conductive material to a certain amount. This provides pressure data for the application of thermally conductive material sheets and provides accurate data support for OEM design schemes. Attached Figure Description

[0023] This utility model is equipped with a compression device 2 and a data acquisition device 3 to perform compression testing. The compression device 2 is set on the test platform 1 and includes a driver 21 and a lifting component 22. The driver 21 is used to drive the lifting component 22 to move vertically closer to or away from the test position 11 for placing the heat-conducting material set on the test platform 1.

The slider 2123 is provided with a through threaded hole 2125. The screw 2122 is rotatably mounted on the bracket 2121 and threadedly connected to the slider 2123 through the threaded hole 2125. The drive end of the servo motor 211 is connected to the screw 2122, and the control end of the servo motor 211 is connected to the drive unit 213. The drive unit 213 is used to control the servo motor 211 to drive the screw 2122 to rotate, so as to drive the slider 2123 to move the lifting component 22 vertically along the groove 2124, which is beneficial to achieve precise compression control.

[0025] Specifically, in this embodiment, the drive unit 213 is a servo driver. The drive unit 213 controls the servo motor 211 to drive the screw 2122 to rotate, thereby realizing the lifting and lowering movement of the slider 2123, and thus realizing the control of the linear reciprocating motion of the lifting component 22, but is not limited thereto.

[0026] See Figures 1 to 4 The lifting component 22 includes a connecting part 221, a pressure sensor 23, and a compression contact part 222. The pressure sensor 23 is vertically adjustable and mounted on the bottom surface of the connecting part 221, and the compression contact part 222 is vertically adjustable and mounted on the bottom surface of the pressure sensor 23.

[0027] Furthermore, the bottom surface of the connecting part 221 is provided with a first threaded hole 2211, the top and bottom surfaces of the pressure sensor 23 are provided with a first threaded post 231 and a second threaded post 232, and the fixed surface of the compression contact part 222 is provided with a second threaded hole 2221.

[0029] Specifically, in this embodiment, the radial diameter of the boss 112 of the test seat 111 is 28.66 (one square inch), but is not limited thereto.

[0030] See Figures 1 to 4 The thermally conductive material compression testing equipment also includes a controller 4 and a display 5. The controller 4 is connected to the driver 21, the data acquisition unit 3 and the display 5 respectively. The controller 4 is used to control the distance that the driver 21 drives the lifting component 22 to move vertically and to transmit the pressure value read by the data acquisition unit 3 to the display 5 for display.

[0031] Specifically, in this embodiment, the data acquisition device 3 is a PLC data acquisition card connected to the pressure sensor 23, and the controller 4 is a control PCB board. The thermal conductive material compression testing equipment controls the servo motor 211 through the drive unit 213 to drive the lifting component 22 equipped with the pressure sensor 23 to apply a certain pressure to the thermal conductive material placed on the test position 11, so that the thermal conductive material is compressed to a certain thickness. The high-speed data acquisition card is used to synchronously collect the displacement data of the lifting component 22 and the pressure data of the pressure sensor 23 in real time, so as to control the vertical displacement of the lifting component 22 and record the maximum pressure required to compress the thermal conductive material to a certain amount and the stable pressure required to maintain the thermal conductive material at a certain amount. The test data is used to generate (plot) a curve of pressure (the required maximum pressure and the stable pressure) versus compression amount (compression ratio), but it is not limited to this.
