[0003] In order to ensure that the interface heat dissipation material will not be affected by environmental pollution, mechanical damage and other environmental factors during storage or transportation, the interface heat dissipation material needs to be packaged through a package (the package can be a carrier tape or tray, or other packaging methods). During packaging, a piece of interface heat dissipation material is placed in a pocket of the package. Putting too little, too much or the interface heat dissipation material placed is not the expected type (that is, the interface heat dissipation material placed is not a single piece of the expected material and expected thickness) will cause unqualified packaged products to flow into the subsequent production line, causing the packaged product to fail.

[0013] Specific embodiments are given below to introduce the technical solution of the present application in detail.

[0014] Figure 1 This is a schematic diagram of the implementation principle of the detection device embodiment 1 provided in this application. Please refer to Figure 1 The detection device provided in this embodiment is used to detect the state of the interface heat dissipation material packaging structure; the interface heat dissipation material packaging structure includes a packaging body and an interface heat dissipation product packaged in the packaging body; the state includes normal and abnormal. When the interface heat dissipation product packaged in the packaging body is of the expected type and is a single piece, the interface heat dissipation material packaging structure is in a normal state, otherwise the interface heat dissipation material packaging structure is in an abnormal state; interface heat dissipation products of different materials and / or different thicknesses belong to different types; the detection device includes a frame 1, at least one type of sensor 2, and a controller 3 electrically connected to the at least one type of sensor 2; wherein, The frame 1 includes a sensor mounting portion 11 and a receiving platform 12; the at least one type of sensor 2 is mounted on the sensor mounting portion 11; the receiving platform 12 is used to place a packaging structure of a heat dissipation material of an interface to be measured; The controller 3 is used to control the at least one type of sensor 2 to enter a working state in response to a test instruction triggered by a user; The at least one type of sensor 2 is used to sense the physical property changes of the heat dissipation material packaging structure of the interface to be tested placed on the accommodating table 12 in real time through the corresponding detection mechanism in the working state, generate a detection signal according to the physical property changes, and send the detection signal to the controller 3; The controller 3 is further used to determine the state of the packaging structure of the heat dissipation material of the interface to be tested according to the detection signal of the at least one type of sensor 2.

[0015] Specifically, thermal interface materials (TIMs) are materials used to improve the efficiency of heat conduction between different components in electronic devices. They are usually used between heat sources (such as processors, power components) and heat sinks or cooling systems to reduce thermal resistance and ensure that heat is effectively conducted from the heat source to the heat sink, thereby preventing the device from overheating and improving its performance and life. For example, in one possible implementation, the interface heat dissipation product 200 made of interface heat dissipation materials may include indium sheets, indium alloys, tin sheets, tin alloys, graphite sheets, and thermally conductive ceramics.

[0016] Referring to the above description, it can be understood that the interface heat dissipation material packaging structure refers to a packaged interface heat dissipation product, which includes a packaging body and an interface heat dissipation product packaged in the packaging body. Further, the packaging body can be a carrier tape or Tray, which is not limited in this embodiment.

[0017] The detection device and detection method provided in the present application are used to detect the state of the interface heat dissipation material packaging structure, and the state includes normal and abnormal. The state of the interface heat dissipation material packaging structure is introduced below: Specifically, Figure 2 This is a schematic diagram of an interface heat dissipation material packaging structure exemplarily shown in this application. Figure 2 , Figure 2 Figure A in the figure is a schematic diagram corresponding to the empty film type. Figure 2 Figure B in the figure is a schematic diagram corresponding to the single-chip type. Figure 2 Figure C in is a schematic diagram corresponding to the stacking type. The state of the interface heat dissipation material packaging structure includes a normal state and an abnormal state. The normal state refers to the state when the interface heat dissipation product 200 in the interface heat dissipation material packaging structure is of the desired type and is a single piece, otherwise, the interface heat dissipation material packaging structure is in an abnormal state. It should be noted that for the interface heat dissipation product 200, due to the design requirements of actual production, the material of the interface heat dissipation product 200 and the thickness of the single-piece interface heat dissipation product 200 are different. It can be understood that interface heat dissipation products 200 of different materials and / or different thicknesses belong to different types. That is, when the materials of the two interface heat dissipation products 200 are different, they belong to different types of interface heat dissipation products 200, or, when the materials of the two interface heat dissipation products 200 are the same but the thicknesses are different, they belong to different types of interface heat dissipation products 200, or, when the materials of the two interface heat dissipation products 200 are different and the thicknesses are different, the two interface heat dissipation products 200 also belong to different types.

[0018] It should be noted that the expected type is set according to actual needs and is not limited in this embodiment. For example, in one embodiment, the expected type is an indium sheet with a thickness of 1.0 mm.

[0019] The detection device provided in this embodiment is introduced below: Specifically, the detection device includes a frame 1, on which a sensor mounting portion 11 and a receiving platform 12 are provided, wherein the sensor mounting portion 11 is used to install at least one type of sensor 2 mentioned above, and the receiving platform 12 is used to place the packaging structure of the heat dissipation material of the interface to be detected.

[0020] Optionally, in order to prevent the frame 1 from interfering with the sensor and improve the accuracy of detection, the frame 1 can be made of non-metallic material.

[0021] It should be noted that at least one type of sensor 2 is used to sense the changes in the physical properties of the interface heat dissipation material packaging structure to be tested placed on the accommodating table 12 in real time through a corresponding detection mechanism in a working state, and to generate a detection signal according to the changes in its physical properties, and to send the detection signal to the controller 3.

[0022] Optionally, the change in physical properties includes at least one of the following specific physical changes: changes in light, capacitance, resistance, sound waves, magnetic fields, distance and pressure.

[0023] Specifically, the controller 3 controls at least one type of sensor 2 to enter a working state in response to a test instruction triggered by a user, and determines the state of the heat dissipation material packaging structure of the interface to be tested according to the detection signal of the at least one type of sensor 2 .

[0024] It should be noted that the test instruction can be actively triggered by the user, and can be used to trigger the test instruction after the interface heat dissipation material packaging structure to be tested is placed on the accommodating table 12 to instruct the detection device to start working.

[0025] In specific implementation, when it is necessary to perform status detection on the interface heat dissipation material to be tested, the packaging structure of the interface heat dissipation material to be tested is placed on the accommodating table 12, and further, a test instruction is triggered. When the control instruction is detected, the controller 3 responds to the test instruction to control at least one type of sensor 2 to enter a working state. For example, one sensor among at least one type of sensors 2 can be controlled to enter a working state. After the sensor enters the working state, it senses the changes in the physical properties of the packaging structure of the interface heat dissipation material to be tested in real time, and generates a detection signal according to the changes in the physical properties. Further, the detection signal is sent to the controller 3, and the controller 3 determines the status of the packaging structure of the interface heat dissipation material to be tested according to the detection signal of at least one type of sensor 2.

[0026] It should be noted that different detection signals correspond to different states of the interface heat dissipation material packaging structure to be tested, so the controller 3 can determine the state of the interface heat dissipation material packaging structure to be tested according to the detection signal. For example, in a possible implementation, the controller 3 can pre-store standard signals corresponding to interface heat dissipation material packaging structures of different states, and it can compare the detection signal from the sensor 2 with the standard signal to determine the state of the interface heat dissipation packaging structure to be tested.

[0027] Optional, Figure 3 This is a schematic diagram of the detection device shown in Example 2 of this application, please refer to Figure 3 The frame 1 includes a top plate 13, a bottom plate 14 and a clamping arm 15; the top plate 13 and the bottom plate 14 are clamped on the clamping arm 15 in a relative and parallel manner; the top plate 13 and the bottom plate 14 constitute the sensor mounting portion 11; wherein, The at least one type of sensor 2 includes a distance sensor 21, a pressure sensor 22 and a visual sensor 23; the distance sensor 21 is installed on the top plate 13, and a placement area 18 matching the distance sensor 21 is provided on the bottom plate 14, the placement area 18 constitutes a receiving platform 12 for accommodating the interface heat dissipation material packaging structure to be tested, the pressure sensor 22 is provided at the bottom of the receiving platform 12, and the visual sensor 23 is arranged at the edge position of the top plate 13 away from the clamping arm 15; wherein the distance sensor 21 is used to test the thickness of the interface heat dissipation product packaged in the interface heat dissipation material packaging structure to be tested accommodated in the placement area 18, and the pressure sensor 22 is used to test the pressure of the interface heat dissipation material packaging structure to be tested accommodated in the placement area 18; the visual sensor 23 is used to obtain a side view of the interface heat dissipation material packaging structure to be tested accommodated in the placement area 18; The controller 3 is used to determine the placement type of the heat dissipation material packaging structure of the interface to be tested according to the side view; the placement type includes a blank sheet, a single sheet and a stacked sheet; The controller 3 is further used to determine that the state of the packaging structure of the heat dissipation material of the interface to be tested is abnormal when the type of the placed object is an empty sheet or a stacked sheet; The controller 3 is further used to determine the state of the packaging structure of the heat dissipation material of the interface to be measured according to the thickness measured by the distance sensor 21 and the pressure measured by the pressure sensor 22 when the type of the placed object is a single piece.

[0028] For details, please refer to Figure 3The frame 1 includes a top plate 13 and a bottom plate 14, and the top plate 13 and the bottom plate 14 are parallel. Further, the distance sensor 21 is installed on the side of the top plate 13 facing the bottom plate 14. A placement area 18 is provided on the bottom plate 14 at a position opposite to the distance sensor 21, and the packaging structure of the heat dissipation material of the interface to be measured is placed in the placement area 18, the visual sensor 23 is installed at the edge of the side of the top plate 13 facing the bottom plate 14 away from the clamping arm 15, and the pressure sensor 22 is installed at the bottom of the accommodating table 12.

[0029] It should be noted that a power supply interface for connecting the distance measuring sensor 21, the pressure sensor 22 and the visual sensor 23 to the controller 3 is also installed on the top plate 13, so that after the distance measuring sensor 21, the pressure sensor 22 and the visual sensor 23 are installed, they can be connected to the controller 3.

[0030] Referring to the previous description, it can be understood that the bottom plate 14 is used to place the heat dissipation material packaging structure of the interface to be measured, and the placement area 18 for placing the heat dissipation material packaging structure of the interface to be measured constitutes a receiving platform 12, and the receiving platform 12 matches the distance sensor 21 and the visual sensor 23 on the top plate 13 and the pressure sensor 22 on the bottom plate 14 (for example, the receiving platform 12 is directly opposite to the distance sensor 21 and the pressure sensor 22, and is within the detection range of the visual sensor 23; for another example, the receiving platform 12 is within the detection range of the distance sensor 21, the visual sensor 23 and the pressure sensor 22), so that the distance sensor 21, the pressure sensor 22 and the visual sensor 23 can detect the heat dissipation material packaging structure of the interface to be measured.

[0031] Furthermore, the clamping arm 15 is used to fix the top plate 13 and the bottom plate 14. The clamping arm 15 can fix the top plate 13 and the bottom plate 14 in a suitable position and can ensure the stability of the detection device during the detection process.

[0032] Specifically, when the visual sensor 23 is used to detect the placement type of the interface heat dissipation material packaging structure, the visual sensor 23 can obtain a side view of the interface heat dissipation material packaging structure on the placement area 18, and determine the placement type of the interface heat dissipation material packaging structure on the placement area 18 according to the side view, wherein the placement type includes three types: empty sheet, single sheet, and stacked sheet. The empty sheet type refers to the interface heat dissipation material packaging structure in which the package body does not contain an interface heat dissipation product, that is, the package body is empty; the single sheet type refers to the interface heat dissipation material packaging structure in which a piece of interface heat dissipation product is packaged; and the stacked sheet type refers to the interface heat dissipation material packaging structure in which two or more pieces of interface heat dissipation products are packaged.

[0033] Specifically, when the distance measuring sensor 21 is used to detect the thickness of the interface heat dissipation material packaging structure, when the distance between the distance measuring sensor 21 and the base plate 14 is fixed, after the interface heat dissipation material packaging structure to be measured is placed on the base plate 14, the interface heat dissipation products packaged therein are different, and the distance from the distance measuring sensor 21 to the interface heat dissipation products is different. Based on this, the thickness of the interface heat dissipation product can be detected, that is, for interface heat dissipation products of different thicknesses, the distance measuring sensor 21 will detect different detection signals. Therefore, the controller 3 can determine the thickness of the interface heat dissipation product according to the detection signal of the distance measuring sensor 21.

[0034] Specifically, when the pressure sensor 22 is used to detect the pressure of the interface heat dissipation material packaging structure, the pressure sensor 22 detects the pressure of the interface heat dissipation material packaging structure on the placement area 18. For different types of interface heat dissipation products, the pressure sensor 22 will detect different detection signals. Therefore, the controller 3 can determine the pressure of the interface heat dissipation material packaging structure based on the detection signal of the pressure sensor 22.

[0035] In specific implementation, the controller 3 can first determine the placement type of the interface heat dissipation material packaging structure based on the side view of the visual sensor 23, and when its placement type is an empty sheet or a stacked sheet, directly determine that the state of the interface heat dissipation material packaging structure to be tested is abnormal; and when the placement type of the interface heat dissipation material packaging structure is a single sheet, further determine the state of the interface heat dissipation material packaging structure to be tested based on the thickness measured by the distance sensor 21 and the pressure measured by the pressure sensor 22.

[0036] Optionally, determining the state of the heat dissipation material packaging structure of the interface to be measured according to the thickness measured by the distance measuring sensor 21 and the pressure measured by the pressure sensor 22 includes: (1) Calculating the density of the interface heat dissipation product packaged in the interface heat dissipation material packaging structure to be measured based on the thickness measured by the distance measuring sensor 21 and the pressure measured by the pressure sensor 22.

[0037] Specifically, the density of the interface heat dissipation product packaged in the interface heat dissipation material packaging structure to be tested can be calculated according to the following formula: ; Among them, the The density of the interface heat dissipation product; The P is the pressure measured by the pressure sensor; Said is the acceleration due to gravity; Said is the thickness measured by the distance measuring sensor.

[0038] It can be understood that the density of the heat dissipation material packaging structure of the interface to be tested satisfies the following first formula: ; in, The quality of the interface heat dissipation product; The area of ​​the interface heat dissipation product; The density of the interface heat dissipation product; The thickness measured by the distance sensor.

[0039] Furthermore, the pressure of the heat dissipation material packaging structure at the interface to be measured satisfies the following second formula: ; Wherein, P is the pressure measured by the pressure sensor; The quality of the interface heat dissipation product; The area of ​​the interface heat dissipation product; is the acceleration due to gravity.

[0040] Therefore, by combining the first formula and the second formula, a calculation formula for calculating the density of the interface heat dissipation product packaged in the interface heat dissipation material packaging structure to be tested is obtained.

[0041] (2) When the density is within the standard density range corresponding to the expected type, and the thickness is within the standard single-chip thickness range corresponding to the expected type, determining that the state of the interface heat dissipation material packaging structure is normal; otherwise, determining that the state of the interface heat dissipation material packaging structure is abnormal.

[0042] Specifically, different expected types correspond to interface heat dissipation products of different materials and / or different thicknesses, and interface heat dissipation products of different materials and / or different thicknesses have different standard density ranges and standard single-piece thicknesses. According to the expected type required in actual production, the standard density range and standard single-piece thickness corresponding to the type are found, and the detected density is compared with the standard density range, and the thickness is compared with the standard single-piece thickness. If the detected density and thickness are both in line with the standard density range and the standard single-piece thickness, the state of the interface heat dissipation material packaging structure is determined to be normal, otherwise, the state of the interface heat dissipation material packaging structure is determined to be abnormal.

[0043] It should be noted that the standard density range and the standard single-sheet thickness are set in advance and pre-stored in the controller 3 .

[0044] The detection device provided in this embodiment is provided with a frame, at least one type of sensor and a controller, and a sensor mounting portion and a receiving platform are provided on the frame, so that at least one type of sensor can be provided on the sensor mounting portion, and when the state of the interface heat dissipation material packaging structure to be tested needs to be tested, the interface heat dissipation material packaging structure to be tested is placed on the receiving platform, so that at least one type of sensor can be used to sense the physical property changes of the interface heat dissipation material packaging structure to be tested placed on the receiving platform in real time, and a detection signal is generated according to the physical property changes, and the detection signal is sent to the controller, and the controller is used to determine the state of the interface heat dissipation material packaging structure to be tested according to the detection signal of the at least one type of sensor. In this way, it is possible to efficiently and accurately identify abnormal conditions such as empty sheets, stacked sheets, and mixed materials, avoid the inflow of unqualified products, and avoid the failure of the packaged products.

[0045] Optional, Figure 4 This is a schematic diagram of the detection device shown in Example 3 of the present application, please refer to Figure 4 The frame 1 includes a top plate 13, a bottom plate 14 and a clamping arm 15; the top plate 13 and the bottom plate 14 are clamped on the clamping arm 15 in a relative and parallel manner; the top plate 13 constitutes the sensor mounting portion; wherein, The at least one type of sensor includes a distance sensor 21; the distance sensor 21 is installed on the top plate 13, and a placement area 18 matching the distance sensor 21 is provided on the bottom plate 14, and the placement area 18 constitutes a receiving platform 12 for receiving the package structure of the interface heat dissipation material to be measured; wherein the distance sensor 21 is used to test the distance between the distance sensor and the package structure of the interface heat dissipation material to be measured accommodated on the placement area 18; The controller 3 is used to compare the detection signal of the distance measuring sensor 21 with the standard distance detection signal corresponding to the expected type, and determine the state of the heat dissipation material packaging structure of the interface to be measured according to the comparison result.

[0046] For details, please refer to Figure 4 The frame 1 includes a top plate 13 and a bottom plate 14, and the top plate 13 and the bottom plate 14 are parallel. Further, the distance sensor 21 is installed on the side of the top plate 13 facing the bottom plate 14. A placement area 18 is provided on the bottom plate 14 at a position opposite to the distance sensor 21, and the packaging structure of the heat dissipation material of the interface to be measured is placed in the placement area 18.

[0047] It should be noted that a power supply interface for connecting the distance measuring sensor 21 and the controller 3 is also installed on the top plate 13, so that after the distance measuring sensor 21 is installed, it can be connected to the controller 3.

[0048] Referring to the previous description, it can be understood that the bottom plate 14 is used to place the interface heat dissipation material packaging structure to be measured, and the placement area 18 for placing the interface heat dissipation material packaging structure to be measured constitutes a receiving table 12, and the receiving table 12 matches the distance measuring sensor 21 on the top plate 13 (for example, the position of the receiving table 12 and the distance measuring sensor 21 is opposite, and for another example, the receiving table 12 is within the detection range of the distance measuring sensor 21.), so that the distance measuring sensor 21 can detect the interface heat dissipation material packaging structure to be measured.

[0049] Furthermore, the clamping arm 15 is used to fix the top plate 13 and the bottom plate 14. The clamping arm 15 can fix the top plate 13 and the bottom plate 14 in a suitable position and can ensure the stability of the detection device during the detection process.

[0050] Specifically, when the distance measuring sensor 21 is used to detect the type of the interface heat dissipation material packaging structure, when the distance between the distance measuring sensor 21 and the base plate 14 is fixed, after the interface heat dissipation material packaging structure to be tested is placed on the base plate 14, different types of interface heat dissipation products have different distances from the distance measuring sensor 21 to the packaging body of the interface heat dissipation material structure (see Figure 2 , the distance from the distance measuring sensor 21 to the pocket is different), that is, for different types of interface heat dissipation material packaging structures, the distance measuring sensor 21 will detect different detection signals. Therefore, the controller 3 can determine the state of the interface heat dissipation material packaging structure according to the detection signal of the distance measuring sensor 21.

[0051] In specific implementation, the controller 3 may compare the detection signal of the distance measuring sensor 21 with the standard distance detection signal corresponding to the expected type, and determine the state of the packaging structure of the heat dissipation material of the interface to be measured according to the comparison result.

[0052] It should be noted that the standard distance detection signal corresponding to the expected type is detected in advance and pre-stored in the controller 3. For example, in a possible implementation, after the frame 1 is installed, while keeping the detection distance between the distance sensor 21 and the bottom plate 14 unchanged, the distance sensor 21 can be used to detect the interface heat dissipation material packaging structure of the expected type in the normal state, thereby obtaining the standard distance detection signal corresponding to the expected type.

[0053] It should be noted that the detection distance corresponding to the interface heat dissipation material packaging structure of the same thickness is the same. When detecting the interface heat dissipation material packaging structure of the same thickness, the detection distance should remain the same, that is, the detection distance between the ranging sensor 21 and the base plate 14 should remain unchanged.

[0054] Furthermore, in a possible implementation, in order to adapt to interface heat dissipation material packaging structures of different thicknesses, the top plate 13 and the bottom plate 14 can also be clamped on the clamping arm 15 in an adjustable manner to adjust the distance between the top plate 13 and the bottom plate 14 so as to place interface heat dissipation materials of different thicknesses therebetween.

[0055] Specifically, for example, in one possible implementation, an adjustment knob can be set at the connection between the clamping arm 15 and the top plate 13 and / or an adjustment knob can be set at the connection between the clamping arm 15 and the bottom plate 14, and the position of the top plate 13 and the bottom plate 14 can be adjusted by the adjustment knob to change the distance between the two.

[0056] In this way, by changing the distance between the top plate 13 and the bottom plate 14, different thicknesses of interface heat dissipation material packaging structures can be adapted, ensuring that the interface heat dissipation material packaging structure to be tested is in a suitable position, thereby improving the efficiency and accuracy of the test.

[0057] Referring to the above description, for interface heat dissipation materials of different thicknesses, after adjusting the distance between the top plate 13 and the bottom plate 14, it is necessary to recalibrate the standard distance detection signal, and then perform status detection based on this.

[0058] Optionally, in a possible implementation, the ranging sensor 21 is any one of the following sensors: a millimeter wave radar sensor, an ultrasonic sensor, a photoelectric ranging sensor, a capacitive ranging sensor, a Hall effect ranging sensor, and a resistive ranging sensor.

[0059] Specifically, when using a millimeter-wave radar sensor to detect the interface heat dissipation material packaging structure, the interface heat dissipation material packaging structure is placed in the placement area, the millimeter-wave radar sensor transmits a millimeter-wave signal, and the millimeter-wave signal reaches the interface heat dissipation material packaging structure and is reflected back to the millimeter-wave radar sensor. The millimeter-wave radar sensor generates a detection signal based on the reflected millimeter-wave signal.

[0060] It should be noted that the change information of the millimeter wave signal reflected back from different types of interface heat dissipation material packaging structures is different. Therefore, the millimeter wave radar sensor can generate different detection signals according to the change information of the millimeter wave signal reflected back.

[0061] Similarly, when an ultrasonic sensor is used to detect an interface heat dissipation material packaging structure, the ultrasonic sensor emits an ultrasonic wave, which is reflected back to the ultrasonic sensor after reaching the interface heat dissipation material packaging structure, and the ultrasonic sensor generates a detection signal based on the change information of the reflected ultrasonic wave. It should be noted that the change information of the ultrasonic wave reflected back from different types of interface heat dissipation material packaging structures is different, and the ultrasonic sensor can generate different detection signals based on the change information of the reflected ultrasonic wave.

[0062] Similarly, when using a photoelectric distance measuring sensor to detect the interface heat dissipation material packaging structure, the photoelectric distance measuring sensor can use a variety of technologies to detect the interface heat dissipation material packaging structure, and the laser distance measuring sensor is used as an example for explanation below.

[0063] Specifically, the laser ranging sensor emits a laser, which is reflected back after reaching the interface heat dissipation material packaging structure. Since different types of interface heat dissipation material packaging structures are at different distances from the laser ranging sensor, the laser ranging sensor can generate a corresponding detection signal based on the time of the reflected laser.

[0064] Similarly, when a capacitive distance measuring sensor is used to detect an interface heat dissipation material packaging structure, the capacitive distance measuring sensor measures distance by detecting a change in capacitance between the sensor and the interface heat dissipation material packaging structure. It is understandable that different types of interface heat dissipation material packaging structures will cause the capacitance in the capacitive distance measuring sensor to change, and the capacitive distance measuring sensor generates a corresponding detection signal according to the change in capacitance.

[0065] Optional, Figure 5 For a schematic diagram of the fourth embodiment of the detection device provided in this application, please refer to Figure 5 The frame body 1 includes a base frame 16 and a receiving plate 17 disposed on the base frame 16; the receiving plate 17 constitutes the sensor mounting portion; wherein, The at least one type of sensor includes a pressure sensor 22; the pressure sensor 22 is mounted on the accommodating plate 17, and a placement area 18 matching the pressure sensor 22 is provided on the base frame 16, and the placement area 18 constitutes a accommodating table 12 for accommodating the interface heat dissipation material packaging structure to be tested; wherein the pressure sensor 22 is used to test the pressure of the interface heat dissipation material packaging structure to be tested accommodated in the placement area 18; The controller 3 is used to compare the detection signal of the pressure sensor 22 with the standard pressure detection signal corresponding to the expected type, and determine the state of the packaging structure of the heat dissipation material of the interface to be tested according to the comparison result.

[0066] For details, please refer to Figure 5 The frame 1 includes a base frame 16 and a receiving plate 17. The base frame 16 is used to place the receiving plate 17 to ensure the stability of the detection device during the detection process. The receiving plate 17 is used to install the pressure sensor 22. Furthermore, a placement area 18 for placing the packaging structure of the interface heat dissipation material to be tested is provided on the base frame 16, and the placement area matches the pressure sensor 22.

[0067] In specific implementation, the interface heat dissipation material packaging structure to be tested is placed in a placement area matching the pressure sensor 22. Since the weights of the interface heat dissipation material packaging structures in different states are different, the pressures applied to the pressure sensor 22 are also different. The interface heat dissipation material packaging structures in different states correspond to different standard pressure signals. Therefore, the pressure sensor 22 can generate a detection signal by detecting the pressure applied by the interface heat dissipation material packaging structure to be tested on the placement area. The controller 3 can determine the state of the interface heat dissipation material packaging structure by comparing the detection signal output by the pressure sensor 22 with the standard pressure detection signal corresponding to the expected type.

[0068] Optional, Figure 6 For a schematic diagram of the fifth embodiment of the detection device provided in this application, please refer to Figure 6 , the detection device also includes an audible and visual alarm device 4, and the audible and visual alarm device 4 is connected to the controller 3; wherein, The controller 3 is also used to determine the state of the heat dissipation material packaging structure of the interface to be tested according to the detection signal, select the target sound and light alarm mode corresponding to the state according to the currently determined state, and control the sound and light alarm device 4 to alarm in the target sound and light alarm mode.

[0069] Specifically, the sound and light alarm device 4 can work in different modes. It works in a corresponding mode according to the currently determined state of the interface heat dissipation material packaging structure, that is, different states correspond to different sound and light alarm device working modes.

[0070] It should be noted that the specific working modes included in the sound and light alarm device 4 are set according to actual needs, and are not limited in this embodiment. For example, in one embodiment, the sound and light alarm device 4 includes an A mode and a B mode, and the A mode and the B mode are different, wherein the A mode corresponds to a normal state and the B mode corresponds to an abnormal state. It can be understood that when the currently determined state is a normal state, the controller 3 controls the sound and light alarm device 4 to work in the A mode, and when the currently determined state is an abnormal state, the controller 3 controls the sound and light alarm device 4 to work in the B mode.

[0071] Furthermore, the specific contents of mode A and mode B are set according to actual needs and are not limited in this embodiment. For example, in a possible implementation, the specific contents of mode A are: green light on; the specific contents of mode B are: red light on, and the following contents are played in a loop: abnormal status.

[0072] In combination with the above example, for example, in one embodiment, when it is detected that the state of the interface heat dissipation material packaging structure is normal, the controller 3 controls the sound and light alarm device 4 to light up a green light, and controls the sound and light alarm device 4 not to play any sound information; when it is detected that the state of the interface heat dissipation material packaging structure is abnormal, the controller 3 controls the sound and light alarm device 4 to light up a red light, and controls the sound and light alarm device 4 to play the following information in a loop: "State is abnormal" until the interface heat dissipation material packaging structure is manually processed.

[0073] The detection device provided in this embodiment can display different sound and light modes when detecting interface heat dissipation material packaging structures in different states by setting up a sound and light alarm device, so as to provide real-time visual and auditory feedback through different sound and light mode reminders, thereby ensuring that the user can immediately obtain the detection results during the detection process and respond quickly to the detection results.

[0074] Optional, Figure 7 For a schematic diagram of the sixth embodiment of the detection device provided in this application, please refer to Figure 7 , the detection device also includes a liquid crystal display screen 5, and the liquid crystal display screen 5 is connected to the controller 3; wherein, The controller 3 is further configured to display the currently determined state on the liquid crystal display screen 5 after determining the state of the packaging structure of the heat dissipation material of the interface to be tested according to the detection signal.

[0075] Specifically, by setting up a liquid crystal display screen 5, the state of the interface heat dissipation material packaging structure can be displayed on the liquid crystal display screen 5. In specific implementation, the liquid crystal display screen 5 can display the state of the interface heat dissipation material structure in the following display modes: text display, graphic display, graphic and text combination display, color differentiation display, etc. For example, when displayed through text, the name of the state can be displayed in the form of subtitles on the liquid crystal display screen 5. For another example, when displayed through a picture, the icon corresponding to the state can be displayed in the form of a picture on the liquid crystal display screen 5. For another example, when displayed through a combination of text and pictures, the icon corresponding to the state can be displayed as a picture on the liquid crystal display screen 5, and the name of the state can be marked with text below the icon. For another example, when displayed by color differentiation, the color corresponding to the state can be displayed on the liquid crystal display screen 5.

[0076] In combination with the above examples, for example, when the text is displayed directly, when the state is determined to be a normal state, the controller 3 controls the LCD screen 5 to directly display the word "Normal"; for another example, when the graphics and text are displayed in combination, when the state is determined to be a normal state, the controller 3 controls the LCD screen 5 to display a green circle icon with the text description "Normal" next to it; for another example, when the display is differentiated by color, when the state is determined to be a normal state, the controller 3 controls the LCD screen 5 to display "Normal" with a green background.

[0077] The detection device provided in this embodiment can display the detection results intuitively, in detail and in real time through the LCD screen by setting up a liquid crystal display screen, so that users can better understand the detection results, reduce misunderstandings, prevent missing abnormal situations, and improve the accuracy of operations and decisions.

Please refer to Figure 8 The detection method provided in this embodiment is applied to the controller in any of the aforementioned detection devices, and the method includes: S101. In response to a test instruction, control at least one type of sensor in the detection device to enter a working state, so that the at least one type of sensor can sense the changes in the physical properties of the packaging structure of the heat dissipation material of the interface to be tested in real time through a corresponding detection mechanism in the working state, generate a detection signal according to the changes in the physical quantity, and feed the detection signal back to the controller.

[0080] S102: Determine the state of the packaging structure of the heat dissipation material of the interface to be tested according to the detection signal of the at least one type of sensor.

[0081] Specifically, the test instruction is a user-triggered instruction. When the user needs to detect the state of the interface heat dissipation material packaging structure, the interface heat dissipation material packaging structure to be tested is placed on the receiving table, and further, the test instruction is triggered to start the detection device to work.

[0082] Furthermore, after detecting the test instruction, the controller controls at least one type of sensor in the detection device to enter a working state in response to the test instruction.

[0083] It should be noted that, referring to the previous description, it can be understood that the sensor can be a distance sensor or a pressure sensor, and the distance sensor, the visual sensor and the pressure sensor can be controlled to enter the working state at the same time.

[0084] After the sensor enters the working state, it senses the changes in the physical properties of the heat dissipation material packaging structure of the interface to be tested in real time through the corresponding detection mechanism, generates corresponding detection signals according to the changes in the physical properties, and feeds the detection signals back to the controller.

[0085] It should be noted that different detection signals correspond to different states. Therefore, the controller can determine the state of the packaging structure of the heat dissipation material of the interface to be tested according to the detection signal fed back by the sensor.

[0086] The method provided in this embodiment can efficiently and accurately detect the status of the interface heat dissipation material packaging structure.

[0087] The above description is only a preferred embodiment of the present application and is not intended to limit the present application. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present application shall be included in the scope of protection of the present application.
