Description

Technical Field

[0001] The invention relates to the field of detection, and in particular to a thermal conductive plastic quality detection device. Background Art

[0002] Thermal conductivity is the main indicator for measuring the thermal conductivity of materials, and is usually tested using the thermal conductivity method. This method measures the speed of temperature change and the temperature difference after the sample is heated to calculate the thermal conductivity of the sample. At present, in order to ensure the quality of thermal conductive plastics after production, batch quality inspection is generally required, and the core of quality inspection is the thermal conductivity test. During the inspection, the thermal conductive plastic sheet is generally positioned, then heated on one side, and tested by sensors on both sides, so that the thermal conductivity can be tested.

[0003] However, the thermal conductivity detection equipment for thermally conductive plastics in the prior art is generally inefficient.

The second push plate 14 and the first drive plate 17 are displaced as a whole in the direction of the detection disk 2, so that the second push plate 14 pushes the thermally conductive plastic in the second slide groove 24 into the corresponding positioning groove 43, and the first drive plate 17 realizes the outward movement of the second support plate 28, and the thermally conductive plastic continues to fall to the first support plate 27. When the detection disk 2 rotates again, the first drive plate 17 and the second push plate 14 are reset, and the first force plate 18 also drives the traction arm 8 and the second support plate 28 to reset as a whole under the reverse force of the first spring 19, so that the thermally conductive plastic at the bottom falls to the second slide groove 24 to prepare for the next loading, and when the detection disk 2 drives the thermally conductive plastic to rotate, it will gradually enter the inner side of the arc plate 5, so that the roller 41 is pressed to drive the U-shaped frame 40 to move, and the U-shaped frame 40 compresses The second spring 48, so that the third guide wheel 56 drives the second hollow seat 51 to move in the direction of the positioning groove 43 through the first inclined groove 25, and the second hollow seat 51 drives the base plate 52 to clamp the thermally conductive plastic in the positioning groove 43, and the electric heating plate 53 and the sensor 54 are in close contact with the thermally conductive plastic. The electric heating plate 53 heats the thermally conductive plastic, and the two sensors 54 detect from both sides, so that the thermal conductivity detection can be realized. When the roller 41 is separated from the inner side of the arc plate 5, the thermally conductive plastic is released from the clamping. Since the positioning grooves 43 are an even number, when the detection disk 2 stops, the thermally conductive plastic that has been detected just corresponds to the second slide groove 24, and the vertical plate 15 will drive the unloading plate 57 to move horizontally while loading in the direction of the detection disk 2, and the unloading plate 57 will drive the first push plate 13 to move.The first push plate 13 drives the third push plate 44 to move through the second force plate 42. The third push plate 44 cooperates with the second guide rod 49 to compress the third spring 50. Then the third push plate 44 pushes the heat-conducting plastic in the positioning groove 43 to move outward and disengage, thereby realizing unloading. This cycle can realize automatic loading, positioning, detection, and unloading. The overall structure is compact, the linkage is high, the detection accuracy is high, and there is no need for frequent participation of workers, and continuous detection can be realized.
