Description

Technical Field

[0001] This invention relates to the field of gallium nitride device testing, specifically to a gallium nitride device temperature monitoring device and method. Background Technology

[0002] Gallium nitride (GaN) devices are a class of electronic devices made from gallium nitride semiconductor materials. Gallium nitride is a wide bandgap semiconductor material with excellent electronic properties, which makes GaN devices perform well in special applications such as high frequency, high power, and high temperature. The advantages of GaN devices include high power density, high frequency operation, high efficiency, high temperature stability, and fast switching speed. These advantages make GaN devices have broad application prospects in many applications and provide great potential for the further development of the electronics industry.

[0003] As gallium nitride (GaN) devices continue to evolve towards smaller sizes and higher power, the temperature generated and withstood per unit volume of GaN devices is increasing. This leads to a continuous increase in the heat dissipation of GaN HEMT devices, and the impact of self-heating effects on device performance and reliability is becoming increasingly severe. To accurately evaluate the reliability of GaN HEMT devices, accurate measurement of the junction temperature is necessary. The GaN HEMT device junction temperature testing device, test board, test system, and method disclosed in CN201710751882.9 can perform high-precision junction temperature testing on GaN HEMT devices. However, during the testing process, to record the operating state of the GaN device at different temperatures, a monitoring device is required to record the operating state of the GaN device. Existing monitoring devices are relatively simple in function, only capable of basic video surveillance. When gallium nitride (GaN) devices overheat or short-circuit and catch fire during testing, these devices cannot automatically isolate and extinguish the fire in a timely manner. Therefore, the flames can easily cause secondary damage to surrounding equipment. Furthermore, existing devices cannot automatically cut off the connecting cables during GaN device temperature measurement, allowing power to continue flowing to the short circuit point, increasing the risk of fire spread. This results in poor practicality and safety. Additionally, existing devices cannot automatically cool themselves during GaN device monitoring, making the heat generated during testing highly susceptible to adverse effects. Therefore, a GaN device temperature monitoring device and method are needed to meet user needs. Summary of the Invention

[0014] A method of using a gallium nitride device temperature monitoring device includes the following steps: S1: The staff can stand the gallium nitride device upright and use clamps to fix the gallium nitride device, and then place it in the middle of the work frame of the temperature measuring device; S2: By rotating the worm gear and using the meshing worm wheel, the turntable on the rotating shaft can drive the camera devices in the connecting frames on both sides to rotate in a circle. At the same time, in conjunction with the partition and protection components, the working height and working angle of the camera devices can be adjusted so that the two camera devices are aligned with the two end faces of the gallium nitride device. S3: During the testing of gallium nitride devices using temperature measuring devices, the camera equipment on both sides, together with the corresponding infrared temperature sensors and thermal imagers, can record the working status of gallium nitride devices at different temperatures in real time. S4: During the operation of the camera equipment, the combination of multi-level protection components, air ducts, connecting frames and air vents can provide continuous and stable cooling protection for the camera equipment; S5: During the temperature measurement of gallium nitride devices, if overheating or short circuit occurs and causes a fire, the smoke sensor can detect the smoke. At this time, the isolation protection component will automatically fall, thereby automatically covering and protecting the burning gallium nitride device. At the same time, the connecting cable during the temperature measurement of gallium nitride devices will be automatically cut off. Meanwhile, the multi-level protection component can automatically extinguish the fire of the gallium nitride device.

[0015] Compared with the prior art, the beneficial effects of the present invention are: 1. This invention includes a partition and protection component. By rotating the second threaded rods on both sides, the simultaneous upward and downward movement of the second threaded rods on both sides, combined with the telescopic sleeve, allows for convenient adjustment of the working height of the camera equipment. Furthermore, by driving one side of the second threaded rod upward and the other side downward, combined with the limiting block, the working angle of the camera equipment can be conveniently adjusted. This ensures that the two cameras are aligned with the two end faces of the gallium nitride device, guaranteeing the convenience and accuracy of subsequent temperature monitoring. This improves the practicality and applicability of the temperature monitoring device. However, if overheating occurs during the temperature measurement of the gallium nitride device... In the event of a fire caused by a short circuit, the smoke sensor can detect the smoke and control the battery to cut off power. At this time, the electromagnet loses its power and magnetic force, and the connecting frames on both sides and the corresponding protective frames automatically fall to the workbench. This automatically covers and protects the burning gallium nitride device, preventing the flames from adversely affecting other equipment. At the same time, when the connecting frames fall to the workbench, the blades can automatically cut off the connecting cables used in the temperature measurement process of the gallium nitride device, preventing the cables from continuing to supply power to the short circuit and causing the fire to spread. It also reduces the distance between the nozzle and the gallium nitride device, ensuring the stability and efficiency of subsequent dry powder fire extinguishing operations.

[0016] 2. This invention incorporates multi-level protection components. During operation, driven by a small motor, the meshing of the first and second gears drives the exhaust fans on each driven shaft to rotate simultaneously. Combined with the air duct, connecting frame, and air duct holes, this creates a continuous and stable airflow within the connecting frame. Simultaneously, the rotation of each driven shaft drives the screw rod to rotate stably within the conveying cylinder, thus uniformly conveying water from the storage tank to the sponge board. The flowing air evaporates the water in the sponge board, absorbing heat and further enhancing the cooling effect, thereby protecting the equipment during continuous operation. The system stabilizes the temperature of the camera equipment, thereby improving its operational safety and stability. When overheating or short circuits occur during the temperature measurement of the gallium nitride (GaN) device, leading to a fire, a smoke sensor detects the smoke and drives a small motor to rotate in the opposite direction. This small motor, through a drive shaft, drives each spiral blade to rotate stably, automatically delivering the dry powder from the storage box to the GaN device via nozzles on the connecting pipe. This automatically extinguishes the fire on the GaN device, preventing secondary damage to other equipment from the flames on the GaN device and increasing the versatility and safety of the monitoring device.

[0017] 3. This invention includes a worm gear and a worm wheel. By rotating the worm gear, the meshing worm wheel drives the camera devices within the connecting frames on both sides to rotate circumferentially via a turntable on the rotating shaft. Under the rotation of the first threaded rods on both sides, the threaded limit blocks drive the support rods to move towards the center or side. During the movement of the support rods, the magnetic attraction of the electromagnet drives the camera devices within the connecting frames to move towards the center or side via a telescopic sleeve, thereby adjusting the working position of the camera devices. This ensures the accuracy and stability of subsequent temperature monitoring, improving the practicality and applicability of the temperature monitoring device.

[0018] 4. By setting up a connecting conveyor assembly, the rubber pad can use its own gravity to separate the first conveyor belt and the second conveyor belt when it falls. The first through hole and the second through hole inside the separated first roller and second roller are interconnected, so that the tube of the external fire extinguisher bottle can spray the fire extinguishing dry powder from the grid pipe, so as to realize the function of automatically spraying fire extinguishing dry powder when overheated and stopping the forward conveying of gallium nitride device.

An infrared temperature sensor 27 is mounted on one side of the connecting plate 26, and a thermal imager 28 is mounted on the other side. Using the worm gear 3 and the meshing worm wheel 4, the rotating disk 6 on the rotating shaft 5 drives the camera devices 23 within the connecting frames 9 to rotate in a circular motion.

[0028] In this embodiment, a second threaded rod 807 is threadedly connected to the electromagnet 806. A hinge seat 816 is installed at the bottom end of the second threaded rod 807. A sliding block 808 is rotatably connected to the bottom end of the hinge seat 816. The sliding block 808 is slidably connected to the top of the connecting frame 9.

This ensures that the two cameras 23 are aligned with the two end faces of the gallium nitride device, guaranteeing the convenience and accuracy of subsequent temperature monitoring. This enhances the practicality and stability of the temperature monitoring device. In terms of applicability, when the gallium nitride device overheats or short-circuits and catches fire during temperature measurement, the smoke sensor 7 can detect the smoke and control the battery 803 to cut off power through the circuit. At this time, the electromagnet 806 loses power support and the magnetic force disappears. The connecting frames 9 on both sides and the corresponding protective frames 810 automatically fall to the workbench, thereby automatically covering and protecting the burning gallium nitride device to prevent the flame from causing adverse effects on other equipment. At the same time, the distance between the nozzle 1518 and the gallium nitride device is reduced, ensuring the stability and efficiency of subsequent dry powder fire extinguishing work.

The storage box 1515 is fixed in the center of the insulation frame 1501. The connecting pipes 1517 are symmetrically distributed on both sides of the end of the storage box 1515. The connecting pipes 1517 and the nozzles 1518 correspond one-to-one. When overheating or short circuit occurs during the temperature measurement of the gallium nitride device, causing a fire, smoke will be emitted. Sensor 7 can detect smoke and drive the small motor 1503 to rotate in the opposite direction. At this time, the small motor 1503 can drive each spiral blade 1513 to rotate stably through the transmission shaft 1504, thereby automatically delivering the dry powder in the storage box 1515 to the gallium nitride device through the nozzle 1518 on the connecting pipe 1517, and automatically extinguishing the fire on the gallium nitride device. This avoids the flame on the gallium nitride device causing secondary damage to other equipment, and increases the versatility and safety of the monitoring device.

[0030] In this embodiment, a second gear 1506 is meshed with the first gear 1505. The second gear 1506 is fixedly connected to the driven shaft 1507. An exhaust fan 1508 and a screw rod 1509 are fixedly connected to the driven shaft 1507. The screw rod 1509 is rotatably connected inside the conveying cylinder 1510. The conveying cylinder 1510 is fixedly connected inside the liquid storage tank 1511. The liquid storage tank 1511 is fixedly connected to the heat insulation frame 1501. A sponge plate 1512 is fixedly connected inside the heat insulation frame 1501. Both the drive shaft 1504 and the driven shaft 1507 are rotatably connected to the sponge plate 1512. The second gear 1506 is evenly distributed on the first gear 1505. The second gear 1506 corresponds one-to-one with the exhaust fan 1508 through the driven shaft 1507. The length of the screw rod 1509 is equal to the length of the conveying cylinder 1510. The conveying cylinder 1510 and the sponge plate 1508 are connected. With 12 phases in contact, during the operation of the camera device 23, driven by the small motor 1503, the exhaust fans 1508 on each driven shaft 1507 can rotate simultaneously through the meshing of the first gear 1505 and the second gear 1506. In conjunction with the air guide pipe 16, the connecting frame 17 and the air guide hole 18, a continuous and stable airflow can be formed within the connecting frame 9. At the same time, during the rotation of each driven shaft 1507, the screw rod 1509 can be driven to rotate stably within the conveying cylinder 1510, thereby uniformly conveying the water in the liquid storage tank 1511 to the sponge plate 1512. The flowing air can evaporate the water in the sponge plate 1512 and absorb heat, thereby further improving the cooling effect. This can stably cool the camera device 23 during continuous operation, thereby improving the working safety and stability of the camera device 23.

[0031] In this embodiment, the connecting frame 17 is symmetrically distributed on the upper and lower sides of the camera device 23, and the air duct 18 is equidistantly distributed on the connecting frame 17. The connecting frame 17 corresponds one-to-one with the air duct 16. The end cross-section of the second locking block 20 is a right trapezoid. The shape and size of the second locking block 20 are the same as those of the first locking block 12. When the camera device 23 needs to be inspected and maintained after working for a long time, it is only necessary to pull the first locking blocks 12 on the upper and lower sides of the limiting frame 14 outward until the first locking blocks 12 move out of the first slot 11 on the connecting frame 9. At this time, the disassembly of the limiting frame 14 can be easily completed. The limiting frame 14 can remove the camera device 23 from the connecting frame 9 through the connecting frame 17.

[0032] In this embodiment, the connecting conveyor assembly 29 includes a base plate 2901 disposed below the rubber pad 813, a first conveyor belt 2902 mounted on the base plate 2901, a second conveyor belt 2903 disposed on the side of the first conveyor belt 2902, and a fixing block 2904 disposed on the inner side of the first conveyor belt 2902 and the second conveyor belt 2903. The fixing block 2904 and the base plate 2901 are fixedly connected. A first rotating roller 29 is disposed inside the first conveyor belt 2902. 05. A second roller 2908 is provided inside the second conveyor belt 2903. A tube 30 is connected to the first roller 2905. The tube 30 is used to connect to an external fire extinguisher so that when there is a speed difference between the first roller 2905 and the second roller 2908, fire extinguishing dry powder will be automatically sprayed. When the second conveyor belt 2903 is under pressure, the first roller 2905 will slide on the second roller 2908, realizing the function of stopping the gallium nitride device from forward conveying and automatically extinguishing the fire.

[0033] In this embodiment, a mesh pipe 2910 is installed on the second roller 2908, and leaf springs 2911 are installed around the mesh pipe 2910. The leaf springs 2911 ensure that the mesh pipe 2910 remains taut after installation. A damping cylinder 2912 is installed on the mesh pipe 2910. Second through holes 2909 are opened inside the second roller 2908, the mesh pipe 2910, and the damping cylinder 2912. A second baffle 2913 is installed inside the second through hole 2909. The first roller 2905 has a first through hole 2906 inside, and a fixing ring 2914 is fixedly installed inside the first through hole 2906. A first baffle 2907 is fixedly installed inside the fixing ring 2914. When there is a speed difference between the second roller 2908 and the first roller 2905, a gap appears between the first baffle 2907 and the second baffle 2913, so that the dry powder of the fire extinguisher can be sprayed out from the position of the grid pipe 2910 and realize the fire extinguishing function.

[0034] It should be noted that this invention is a gallium nitride (GaN) device temperature monitoring device and method. First, the operator can stand the GaN device upright and fix it with a clamp. Then, place it in the middle of the work frame 1 of the temperature measuring device, and move the cable connected to the GaN device during temperature measurement to both sides. At this time, the operator can rotate the worm gear 3 inside the mounting plate 2. Under the rotation of the worm gear 3, the meshing worm wheel 4 can drive the turntable 6 on the rotating shaft 5 to rotate stably. Under the rotation of the turntable 6, the camera devices 23 inside the connecting frames 9 on both sides can rotate circumferentially. Then, the operator can use the rotating handle 815 to rotate the first threaded rods 801 on both sides. Under the rotation of the first threaded rods 801 on both sides, the threaded limiting block 802 can drive the support rod 804 to move towards the center or side. During the movement of the support rod 804, electromagnetic... Under the magnetic adsorption of the electromagnet 806, the telescopic sleeve 809 can drive the camera device 23 in the connecting frame 9 to move towards the center or side, thereby adjusting the working position of the camera device 23. Then, the operator can rotate the second threaded rods 807 on both sides of the electromagnet 806. Under the thread rotation of the second threaded rods 807, the hinge seat 816 can drive the bottom limit block 802 to move downward or upward. By using the simultaneous upward and downward movement of the first threaded rods 801 on both sides, in conjunction with the telescopic sleeve 809, the working height of the camera device 23 can be easily adjusted. By driving one side of the first threaded rod 801 upward and the other side of the first threaded rod 801 downward, in conjunction with the limit block 802, the working angle of the camera device 23 hinged at the bottom of the telescopic sleeve 809 can be easily adjusted, thereby enabling the two cameras 23 to be easily aligned with the two end faces of the gallium nitride device. Subsequently, during the testing of the gallium nitride device using a temperature measuring device, the cameras 23 on both sides, in conjunction with the corresponding infrared temperature sensors 27 and thermal imagers 28, can record the working status of the gallium nitride device at different temperatures in real time. While the cameras 23 are operating, the small motor 1503 on the dehumidifying mesh plate 1502 drives the first gear 1505 to rotate via the transmission shaft 1504, which in turn drives the second gears 1506 to mesh and rotate. The rotation of the second gears 1506 then drives the exhaust fans 1508 to rotate simultaneously via the driven shaft 1507. The rotation of the exhaust fans 1508 draws air from the connecting frame 9, which is then transported through the sponge plate 1512 to the insulation frame 1501. The air is then steadily transported through the air duct 16. The air is conveyed to the connecting frame 17 and, in conjunction with the air guide hole 18, can be conveyed back to the connecting frame 9 to form air circulation. At the same time, during the rotation of the driven shaft 1507, the screw rod 1509 can be driven to rotate stably in the conveying cylinder 1510, thereby conveying the water in the storage tank 1511 to the sponge board 1512 at a uniform speed. At this time, the flowing air can evaporate the water in the sponge board 1512 and absorb heat, thereby further improving the cooling effect. This can stably cool the camera equipment 23 during continuous operation. Under the rotation of the drive shaft 1504, the feeding direction of each screw blade 1513 is towards the inside of the storage box 1515. Therefore, the dry powder in the storage box 1515 will not be conveyed to the connecting pipe 1517. At the same time, it can prevent the dry powder from clumping during long-term storage, which would affect the stability of subsequent fire extinguishing work. When a gallium nitride (GaN) device catches fire due to overheating or a short circuit during temperature measurement, the smoke sensor 7 detects the smoke and controls the battery 803 to cut off power. At this time, the electromagnet 806 loses its power and its magnetic force disappears. Under the influence of gravity, the connecting frames 9 on both sides move the electromagnet 806 away from the support rod 804. The connecting frames 9 then automatically fall onto the worktable, where the rubber pads 813 provide cushioning protection. The combined action of the protective frames 810 and the protective plates 814 on both sides automatically covers and protects the burning GaN device, preventing the flames from adversely affecting other equipment. Simultaneously, as the connecting frames 9 fall onto the worktable, the blade 817 automatically cuts the connecting cable used in the GaN device's temperature measurement process, preventing further damage to the cable. To address the issue of the fire spreading due to the short circuit, the distance between the nozzle 1518 and the gallium nitride device was reduced. When the smoke sensor 7 detects smoke, it drives the small motor 1503 to rotate in the opposite direction. At this time, the small motor 1503 drives each spiral blade 1513 to rotate in the opposite direction through the transmission shaft 1504. Under the rotation of each spiral blade 1513, the rotating small fan blade 1514 can automatically transport the dry powder in the storage box 1515 to the gallium nitride device through the nozzle 1518 on the connecting pipe 1517, and automatically extinguish the fire on the gallium nitride device, avoiding secondary damage to other equipment caused by the flame on the gallium nitride device. Furthermore, under the rotation of the small fan blade 1514, combined with the one-way air valve 1516, the airflow is kept stable, ensuring the stability of the subsequent dry powder delivery. After the fire extinguishing work is completed, simply lift the connecting frames 9 on both sides and engage the positioning groove 805 on the electromagnet 806 with the bottom end of the support rod 804. At this time, the magnetic force can be used to complete the adsorption and fixation of the connecting frame 9, ensuring the stability of the subsequent working state of the temperature monitoring device. When the camera equipment 23 needs to be inspected and maintained after a long period of operation, simply pull the first locking blocks 12 on the upper and lower sides of the limiting frame 14 outward until the first locking blocks 12 move out of the first locking groove 11 on the connecting frame 9. At this time, the disassembly of the limiting frame 14 can be easily completed. The limiting frame 14 can remove the camera equipment 23 from the connecting frame 9 through the connecting frame 17. Then, the staff only needs to pull the second locking block 20 on the connecting frame 17 outward until the second locking block 20 moves out of the connecting frame 17. When the locking block 20 moves away from the second slot 21 on the fixing plate 22, the camera device 23 can be easily disassembled, facilitating the inspection and maintenance of the camera device 23 and the data transmission device 24. When the camera device 23 needs to be installed, simply place the camera device 23 between the connecting frames 17 on both sides, and the second spring 19 can drive the second locking block 20 to stably engage with the second slot 21 on the fixing plate 22, thus completing the engagement and installation of the camera device 23. Similarly, simply engage the limiting frame 14 to the side of the connecting frame 9, and the first spring 13 can drive the first locking block 12 to engage with the first slot 11 on the connecting frame 9, thus completing the engagement and installation of the limiting frame 14 and ensuring the stability of the subsequent working state of the temperature monitoring device.

[0035] like Figure 15 As shown, the second conveyor belt 2903 on the base plate 2901 is used to transport gallium nitride devices. During the transport process, if the rubber pad 813 falls, the weight of the rubber pad 813 itself will increase the resistance of the first roller 2905 in the first conveyor belt 2902 driving the second roller 2908 in the second conveyor belt 2903 to rotate. At this time, the leaf spring 2911 will no longer hold the mesh pipe 2910 tightly in the first through hole 2906 in the first roller 2905, so that a speed difference will appear between the second baffle 2913 in the second through hole 2909 and the first baffle 2907 in the fixing ring 2914, so that the first through hole 2906 and the second through hole 2909 are connected to each other. At this time, the fire extinguishing dry powder is sprayed out from the pipe body 30 and the mesh pipe 2910 to realize the function of automatic fire extinguishing when the temperature is too high, thereby avoiding a fire.
