A positioning plate is provided on the rear surface of the fixed table. A groove is provided on the positioning plate, and a driving gear is provided in the groove. Both the upper and lower ends of the driving gear are movably attached to translation plates. A shielding cover is connected to each of the two translation plates.

Description

Technical Field

[0001] The present invention relates to the technical field of graphene heat sink detection, and specifically to a performance detection device for graphene heat sinks. Background Art

[0002] Graphene, as a material with high thermal conductivity, when a graphene heat sink made of graphene as the main material is attached to a device in use, it can effectively reduce the surface temperature of the device, and improve the service life and stability of the device in use. After the production and processing of the graphene heat sink are completed, a performance detection device is often required to detect the quality of the graphene heat sink, such as various detections of its heat dissipation effect, etc., to ensure that the graphene heat sink can meet the quality requirements in the later stage.

[0003] When some existing performance detection devices detect the heat dissipation effect of graphene heat sinks, it is necessary to place the graphene heat sink in the performance detection device and tighten it, and then use a heating device to heat the graphene heat sink for a period of time, and regularly use a thermometer to detect the surface temperature of the graphene heat sink. In this detection method, in order to avoid the deviation of the detection results caused by the outdoor environment during the detection process, the performance detection device will be closed for a short time and the detection will be carried out inside it. However, since the heating device and the graphene heat sink are in the same space, after the heating device completes the heat conduction to the graphene heat sink and disconnects the contact with the graphene heat sink, it will dissipate heat on its own, resulting in a change in the internal temperature of the performance detection device, which affects the detection of the heat dissipation performance of the graphene heat sink by the staff at different temperatures.

[0033] Please refer to Figures 1 to 12 , the present invention provides a technical solution: a performance detection device for a graphene heat sink, including a fixed table 1, as Figures 1 - 12 shown in, a positioning plate 2 is fixedly installed on the rear surface of the fixed table 1. A groove is provided on the positioning plate 2, and a driving gear 3 is installed in the groove. The driving gear 3 is composed of a rotating motor and a toothed ring. The toothed ring is fixedly sleeved on the outer wall of the output shaft of the rotating motor, and the rotating motor is fixedly installed in the groove on the positioning plate 2. A translation plate 4 is movably attached to both the upper and lower ends of the driving gear 3. Sliding grooves are provided on the inner walls of the upper and lower sides of the groove on the positioning plate 2, and sliders are slidably installed in the sliding grooves. Each single slider is fixedly connected to a translation plate 4. A shielding cover 5 is fixedly installed on both translation plates 4. A number of mutually meshing teeth are provided on the outer walls of the toothed ring, which is one of the components of the driving gear 3, and on the side of the two translation plates 4 close to each other. During the rotation of the driving gear 3, the two translation plates 4 can be driven to move translationally, so that the two shielding covers 5 shield the opening on the front end surface of the fixed table 1, making the graphene heat sink 12 located in the fixed table 1 in a relatively closed environment during the detection process, similar to the usage environment of electronic devices in real life. And the shielding cover 5 is made of a glass plate, which is convenient for the staff to observe the graphene heat sink 12 located in the fixed table 1 during the detection process.

A driving wheel 8 is provided at the central position of the U-shaped groove on the U-shaped frame 7. A driven wheel 9 is movably attached to the outer wall of the driving wheel 8. Translation tooth plates 10 are movably attached to both the front and rear side walls of the driven wheel 9. The translation tooth plates 10 are closely attached to the inner wall of the U-shaped groove on the U-shaped frame 7. The driving wheel 8 has the same composition structure as the driving gear 3. A number of mutually meshing teeth are provided on the toothed ring, which is one of the components of the driving wheel 8, on the driven wheel 9, and on the translation tooth plates 10. During the rotation of the driving wheel 8, the driven wheel 9 and the translation tooth plates 10 can be driven to move. A clamping component 11 is fixedly installed at the top of each of the two translation tooth plates 10. A graphene heat sink 12 is provided between the two clamping components 11.

[0035] The material clamping assembly 11 includes a fixing plate 43. The bottom end of the fixing plate 43 is fixedly connected to the translation tooth plate 10. A groove is provided on the fixing plate 43, and a locking screw 44 is provided at the top end of the fixing plate 43. The locking screw 44 penetrates through the top plate of the fixing plate 43 and extends into the groove on the fixing plate 43. The bottom end of the locking screw 44 is rotatably connected to a pressing plate 45.

[0036] Place the graphene heat sink 12 in the grooves on the two fixing plates 43. Rotate the locking screw 44 downward so that the pressing plate 45 and the inner wall of the bottom end of the groove on the fixing plate 43 cooperate to clamp and fix the graphene heat sink 12. Then, by controlling the driving wheel 8 to rotate, during the rotation of the driving wheel 8, the driven wheel 9 is driven to rotate, and the two translation tooth plates 10 attached to the driven wheel 9 perform a translation movement, making the graphene heat sink 12 in a taut state.

[0037] There are two fixing frames 14 provided on the detection table 6. There are two temperature measuring components 13 provided between the two fixing frames 14. U-shaped grooves are provided on the fixing frames 14, and the openings of the U-shaped grooves face downward. A rotating screw 23 is rotatably installed on the inner wall of the top end of the U-shaped groove on the fixing frame 14, and the threads on the two rotating screws 23 are opposite. The bottom ends of the rotating screws 23 penetrate through the detection table 6 and extend to the bottom end of the detection table 6. The bottom ends of the two rotating screws 23 are fixedly connected to a fitting tooth disc 49. There is a linkage tooth disc 48 provided between the two fitting tooth discs 49. A number of mutually meshing teeth are provided on the outer walls of the linkage tooth disc 48 and the fitting tooth disc 49. The linkage tooth disc 48 is composed of a tooth disc and an inserted rod. The inserted rod is fixedly installed at the top end of the tooth disc and penetrates through the detection table 6 and extends to the top end of the detection table 6 to be connected to the driven wheel 9. Circular chutes are provided at the bottom ends of the fitting tooth discs 49. Two sliders are provided in the circular chutes, and the bottom ends of the two sliders are both installed with L-shaped inserted plates. Four inserted slots matching the L-shaped inserted plates are provided at the bottom end of the detection table 6. By inserting the L-shaped inserted plates into the inserted slots on the detection table 6, it is convenient to provide support for the fitting tooth disc 49.

[0038] During the process of the driving wheel 8 driving the driven wheel 9 to rotate, the driven wheel 9 will drive the linkage tooth disc 48 at its bottom end to rotate. During the rotation of the linkage tooth disc 48, the two linkage tooth discs 48 will be driven to rotate synchronously, causing the two rotating screws 23 fixedly connected to the linkage tooth disc 48 to rotate, enabling the lifting blocks 24 on the outer walls of the rotating screws 23 to perform a vertical lifting movement during the rotation of the rotating screws 23. That is, after the driven wheel 9 rotates to make the graphene heat sink 12 taut, the heat conducting block 42 can be attached to the top end of the graphene heat sink 12 for heating.

[0039] Lifting blocks 24 are movably sleeved on the outer walls of the two rotating screw rods 23, and the width dimension of the lifting blocks 24 is the same as the width dimension of the U-shaped grooves on the fixed frame 14, ensuring that the rotating screw rods 23 can drive the lifting blocks 24 to move vertically during rotation. A lifting plate 25 is fixedly connected between the two lifting blocks 24. A through hole is provided at the center position of the lifting plate 25, and an installation cylinder 27 is fixedly installed in the through hole. Both the installation cylinder 27 and the inside of the rotating cover 29 are hollow, and heat-insulating and heat-preserving materials such as asbestos are filled inside. A heat-conducting block 42 is movably installed in the installation cylinder 27. A lifting sliding groove is provided on the inner wall of the installation cylinder 27. A sliding connection block is slidably installed in the lifting sliding groove, and the sliding connection block is fixedly connected to the metal copper plate which is one of the components of the heat-conducting block 42, ensuring that the heat-conducting block 42 can only move vertically and avoid rotation. The heat-conducting block 42 is composed of a column and a metal copper plate. The metal copper plate is fixedly connected to the bottom end of the column, and the top end of the column penetrates through the top plate of the installation cylinder 27 and is connected to a disc 40. The top end of the disc 40 is fixedly connected to the bottom end of the movable rod 33, and the bottom end of the disc 40 is connected to the top plate of the installation cylinder 27 through a plurality of return springs 41. A circular groove is provided at the top end of the metal copper plate, and an electric heating rod is provided in the circular groove. By connecting the electric heating rod to an external power supply through a circuit, after power-on, the electric heating rod generates heat and transfers it to the metal copper plate, enabling heat transfer after the metal copper plate fits the graphene heat sink 12. A convex block is fixedly installed on the outer wall of the installation cylinder 27. A hidden groove is provided on the convex block, and a rotating motor 28 is installed in the hidden groove. The output shaft of the rotating motor 28 extends out of the hidden groove on the convex block, and a rotating cover 29 is fixedly sleeved on the outer wall of the output shaft of the rotating motor 28. The diameter dimension of the rotating cover 29 is the same as the diameter dimension of the installation cylinder 27. By driving the rotating cover 29 to rotate and fit the bottom end of the installation cylinder 27 through the rotating motor 28, the opening at the bottom end of the installation cylinder 27 can be blocked, preventing the heat-conducting block 42 with too high residual temperature from continuously dissipating heat in the closed fixed table 1, resulting in deviation of the final detection result of the graphene heat sink 12.

[0040] The lifting plate 25 is provided with two through holes, and lifting rods 30 are movably installed in the two through holes. The top ends of the two lifting rods 30 are commonly connected to a connecting plate 31. The bottom end of the connecting plate 31 is connected to the lifting plate 25 through two connecting springs 26. Two extension plates 32 are provided on the outer wall of the connecting plate 31. A through hole is provided at the center of the connecting plate 31, and a movable rod 33 is movably installed in the through hole. The bottom end of the movable rod 33 is fixedly connected to the disc 40. Two arc plates 34 are fixedly installed on the outer wall of the movable rod 33. Two sliding grooves 35 are provided on the connecting plate 31, and sliding blocks 36 are slidably installed in the sliding grooves 35. Anti-slip sliding grooves are provided on the inner walls on both sides of the sliding groove 35, and anti-slip blocks are slidably installed in the anti-slip sliding grooves, and the anti-slip blocks are fixedly connected to the outer walls of the sliding blocks 36. The two sliding blocks 36 are connected to the inner walls of the sliding grooves 35 through a second connecting spring 37. Connecting vertical rods 38 are fixedly installed on the tops of the two sliding blocks 36, and arc-shaped fitting plates 39 are fixedly installed on the tops of the two connecting vertical rods 38.

[0041] A cross bar 15 is fixedly installed on the fixed frame 14, and a swivel 16 is movably mounted on the outer wall of the cross bar 15, and the swivel 16 is connected to the cross bar 15 by a spiral spring, and a linkage plate 18 is fixedly installed on the top side wall of the swivel 16, and the two linkage plates 18 are respectively on the same plane with the two extension plates 32, so that the linkage plates 18 can contact the extension plates 32 during the rotation process, and a toggle plate 17 is fixedly installed on the left side wall of the swivel 16, and the toggle plate 17 extends to the bottom of the lifting plate 25, and there is a swivel spring movably fitted on the right side wall of the linkage plate 18. A limit baffle 19 is provided, and the limit baffle 19 is fixedly installed on the fixing frame 14. A mounting platform 20 is arranged above the cross bar 15, and the mounting platform 20 is fixedly installed on the fixing frame 14. A groove is provided on the mounting platform 20, and a rotating shaft is provided in the groove. The rotating shaft and the mounting platform 20 are rotatably connected through a volute spring, and a pry plate 21 is fixedly connected to the outer wall of the rotating shaft. The pry plate 21 is movably fitted on the left side wall of the linkage plate 18, and the top end of the pry plate 21 is movably fitted with a limit horizontal plate 22, and the limit horizontal plate 22 is fixedly installed on the mounting platform 20.

[0042] In the process of rotating the screw rod 23 to make the lifting block 24 and the lifting plate 25 move vertically downward, the lifting plate 25 will contact the toggle plate 17, and the toggle plate 17 will rotate through the swivel 16 during the downward movement of the lifting plate 25. During the rotation process, the linkage plate 18 on the swivel 16 will rotate synchronously, and the linkage plate 18 will contact the extension plate 32 during the rotation process, so that the extension plate 32 and the connecting plate 31 move downward. Because the arc-shaped fitting plate 39 is driven to move downward and press the arc-shaped plate 34 to move downward during the movement of the connecting plate 31, the arc-shaped plate 34 is fixedly installed on the outer wall of the movable rod 33, which will cause the movable rod 33, the disc 40, and the heat-conducting block 42 to move downward. , so that the heat conductive block 42 extends out of the inner cavity of the mounting tube 27 and fits with the graphene heat sink 12, and the graphene heat sink 12 is heated. In the process of the lifting plate 25 continuing to fall, the reaction force generated by the arc-shaped fitting plate 39 pressing the arc-shaped plate 34 in the process of moving downward will push the sliding block 36 to slide in the sliding groove 35 until the arc-shaped fitting plate 39 breaks the contact with the arc-shaped plate 34. At this time, the return spring 41 will push the disc 40 and the movable rod 33 to move upward, so that the heat conductive block 42 at the bottom end of the disc 40 moves upward and is collected into the mounting tube 27, and then the rotating cover 29 is driven to rotate by the rotating motor 28 to seal the opening at the bottom end of the mounting tube 27.

[0043] The temperature measuring component 13 includes a mounting frame 46, which is provided with a plurality of through holes, and lifting connecting rods are movably installed in the through holes, and thermometers are installed at the tops of the lifting connecting rods. The thermometer 47 adopts a digital thermometer in the prior art (such as LCD-350 digital thermometer). By installing the probe of the digital thermometer on the top of the lifting connecting rod, the display is placed on the periphery of the fixed platform 1, and the probe and the display are connected by a line, it is convenient to monitor the surface temperature of the graphene heat sink 12 in real time.

[0044] When the present invention is in use, the electrical appliance on the fixed platform 1 is started by an external power supply, the graphene heat sink 12 is placed at the bottom of the groove on the two fixed plates 43, and the locking screw 44 is controlled to rotate downward so that the pressing plate 45 presses and fixes the graphene heat sink 12, and then the driving gear 3 is controlled to rotate so that the translation plate 4 drives the shielding cover 5 to cover the front end opening of the fixed platform 1 during the movement, and the heat conducting block 42 is controlled to generate heat to raise the temperature in the fixed platform 1 to a specified temperature, and then the driving wheel 8 can be controlled to rotate, and the driving wheel 8 drives the driven wheel 9 to rotate, so that the graphene heat sink 12 is attached to the driven wheel 9. The two translation tooth plates 10 move in opposite directions, so that the graphene heat sink 12 is tightened, and during the rotation of the driven wheel 9, the linkage tooth plate 48 at the bottom thereof is driven to rotate and the fitting tooth plate 49 is synchronously rotated. At this time, the rotating screw 23 at the top of the fitting tooth plate 49 rotates synchronously, so that the lifting block 24 and the lifting plate 25 can fall vertically. At this time, the mounting cylinder 27 installed on the lifting plate 25 moves downward, and the lifting plate 25 contacts the toggle plate 17 during the downward movement, and the toggle plate 17 drives the rotating ring 16 and the linkage plate 18 to rotate. The linkage plate 18 contacts the extension plate 32 during the rotation process, causing the extension plate 32 and the connecting plate 31 to move downward, and the arc-shaped fitting plate 39 on the connecting plate 31 drives the arc-shaped plate 34 fitted at its bottom to move downward, and causes the movable rod 33, the disc 40, and the heat-conducting block 42 to move downward and extend out of the mounting tube 27 to fit the graphene heat sink 12, and the heat rod on the heat-conducting block 42 heats up the metal copper plate that is one of the components of the heat-conducting block 42 and transfers it to the graphene heat sink 12. After a period of heat conduction, the lifting plate 25 continues to move downward, and the arc-shaped fitting plate 39 on the connecting plate 31 drives the arc-shaped fitting plate 34 on its bottom to move downward, and causes the movable rod 33, the disc 40, and the heat-conducting block 42 to move downward and extend out of the mounting tube 27 to fit the graphene heat sink 12. When the bonding plate 39 presses the arc plate 34 to move downward, the reverse thrust will cause the sliding block 36 to slide in the sliding groove 35 until the arc bonding plate 39 is out of contact with the arc plate 34. At this time, the disc 40 is pushed upward by the return spring 41 to put the metal copper plate, which is one of the components of the heat conducting block 42, into the mounting tube 27. At this time, the rotating motor 28 is controlled to rotate so that the rotating cover 29 closes the bottom opening of the mounting tube 27, so that the temperature of the graphene heat sink 12 can be monitored in real time through the thermometer 47 attached to the bottom of the graphene heat sink 12.

[0045] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
