If temperature detection is required, the detection process is relatively complex, the structure design is low in integration, the work efficiency is reduced, multiple variables cannot be adjusted simultaneously, the application of the device is reduced, and the functionality is poor. SUMMARY

The output shaft of the first motor passes through the box body and extends to the central rotating tooth. Both ends of the central rotating tooth are meshed with a first gear plate that moves in opposite directions. One end of the first gear plate extends to the upper pressure plate and is connected to the lower pressure plate at the opposite end. The central shaft and the movable shaft on the central rotating tooth are connected by a conveyor belt. One end of the movable shaft is mounted on the atomizer, and the atomizer is equipped with atomizing nozzles arranged in a ring on the movable shaft.

A support platform is provided between the atomizing nozzles on the inner wall of the box.

[0007] Furthermore, the upper pressure plate and the lower pressure plate are connected to the inner wall of the box through telescopic columns. The support platform is equidistantly distributed on the inner wall of the box in a detachable manner. The central rotating tooth and the first gear plate are both placed in the housing. The housing is installed on the side wall of the box by locking it with positioning pins.

[0008] Furthermore, the outer wall of the tensioning wheel is provided with a rolling groove connected to the second bracket, the upper pressure plate and the lower pressure plate are connected with sliding grooves along the height direction of the inner wall of the box, and a sealed cavity connected to the support platform is formed between the upper pressure plate, the lower pressure plate and the inner wall of the box, and one end of the first gear plate is connected with a limit block along the height direction of the side wall of the shell.

[0009] Furthermore, it also includes a combustion testing mechanism, which includes crossbeams placed at both ends of the frame. One end of the crossbeam is connected to a spray gun via a burner. A first support plate is provided between the spray guns at the extended end of the base plate. A conical suction pipe connected to the processing box is provided above the first support plate.

[0010] Furthermore, one end of the conical suction pipe extends to the air pump inside the processing box, the bottom of the air pump is mounted on the second support plate, a second motor is mounted on one end of the outer wall of the processing box, the output shaft of the second motor extends to the small rotating tooth, the outer wall of the small rotating tooth meshes with the large rotating tooth, and the two ends of the outer wall of the large rotating tooth mesh with the vertically distributed second gear plate and third gear plate respectively, and one end of the second gear plate is mounted on the first silencer plate through a bending rod.

[0011] Furthermore, a second silencing plate is connected to both sides of the bottom end of the first silencing plate. The movable end of the second silencing plate is connected to the bottom end of the inner wall of the fixed part through a compression spring, and the movable end of the second silencing plate abuts against and adheres to the bottom of the first silencing plate.

[0012] Furthermore, a silencing cavity is formed between the first silencing plate, the second silencing plate, and the bottom of the inner wall of the processing box. Both the first silencing plate and the second silencing plate are provided with silencing holes that are adapted to them. The second silencing plate is provided with an movable port that is connected to the upper conduit of the air pump. Guide grooves are connected to both the first silencing plate and the second silencing plate near the side wall of the processing box.

[0013] Furthermore, the horizontal extension end of the third gear plate is connected to the push plate, and a water-filled cavity is formed between the push plate and the fixed plate on the inner wall of the treatment box. The air outlet on the cavity extends to the outside of the treatment box through the activated carbon layer. One end of the conduit on the air pump is installed on the U-shaped tube through a one-way flow guide assembly, and the telescopic end on the U-shaped tube is connected to the inner wall of the push plate.

[0014] Furthermore, the unidirectional flow guide assembly includes a rotating shaft placed on the conduit. The outer wall of the rotating shaft is provided with a flow guide plate connected to the side wall of the conduit, and the bottom of the conduit is provided with an arc-shaped groove connected to the flow guide plate. One end of the rotating shaft is fixed to a ratchet, and the corner of the ratchet abuts against a check pawl. One end of the check pawl is connected to a vertical rod by a rotatable connection.

[0015] In summary, due to the adoption of the above technical solution, the beneficial effects of the present invention are: (1) In this invention, the pressure detection mechanism changes the air pressure to adjust the pressure of the chip under different environments, thereby detecting whether there is any pressure damage. The chip is placed on the support platform, the first motor is started and drives the central rotating gear to rotate. Under the action of gear meshing transmission, the upper and lower pressure plates at both ends move in the center, thereby compressing the volume in the sealed cavity and increasing the internal pressure. At the same time, the upper and lower pressure plates will convert into heat during the work process, thereby increasing the internal temperature of the sealed cavity. This can simultaneously increase the internal temperature and pressure of the sealed cavity. In addition, during the rotation of the central rotating gear, the pressure is increased by the following: The conveyor belt drives the atomizing nozzles on the movable shaft to rotate, thus evenly spraying moisture onto the chip and increasing the ambient humidity. Since the chips are distributed on the support platform at different heights, a tensioning wheel is installed on the conveyor belt to effectively spray moisture onto the chips. Together with the first bracket on the atomizer and the second bracket on the tensioning wheel, the power of the conveyor belt can be effectively transmitted, and the atomizer can be moved freely up and down, thereby effectively improving the applicability of the device. By changing the adjustment method of multiple variables, the functionality of the detection device is improved. The design is reasonable and the integrated performance is strong.

[0016] (2) In this invention, the combustion testing mechanism detects the material properties during operation. When the exhaust gas particles generated by combustion can also be purified through the treatment box, environmental pollution can be avoided. The air pump can transport the absorbed smoke particles to the activated carbon layer of the treatment box for filtration and purification. Moreover, according to the use of the air pump, the contact area and time with the water body can be adaptively changed. When the air pump power is large, more smoke particles are transported. At this time, the second motor drives the small rotating gear to rotate. Under the deceleration adjustment, it drives the large rotating gear to rotate. Under the gear meshing transmission, the second gear plate drives the first silencer plate to move upward. Due to the elastic recovery of the compression spring, the movable end of the second silencer plate moves upward, thereby expanding the silencer. The internal volume of the sound chamber is designed to accommodate the large vibration amplitude noise generated when the air pump operates at high power, resulting in a good noise reduction effect. Simultaneously, the third gear plate drives the push plate to move to the right, increasing the water level and extending the contact area and time with the smoke and dust. When the air pump operates at low power, the vibration amplitude of the noise is smaller, and there is relatively less smoke and dust. At this time, the movable end of the second silencer plate moves downward, reducing the internal volume of the silencer chamber. This accommodates the smaller vibration amplitude noise generated when the air pump operates at low power. At the same time, the third gear plate drives the push plate to move to the left, decreasing the water level and shortening the contact area and time with the smoke and dust, accelerating the purification time, and improving work efficiency and environmental protection.

[0017] (3) In this invention, the conduit is connected to a one-way flow guide component in conjunction with a U-shaped tube, which can not only prevent liquid backflow, but also prevent gas backflow, thus playing a one-way adjustment role. The ratchet in conjunction with the check pawl movably connected on the vertical rod can make the rotating shaft drive the guide plate to rotate in one direction, thereby making the smoke flow in one direction. Moreover, the arc groove on the conduit can allow the guide plate to rotate normally, preventing motion interference between structural components, and ensuring stable delivery of smoke, thus improving the stability and safety of the device.

[0021] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0022] Reference manual attached Figure 1 - Appendix Figure 9 As shown, an integrated circuit chip self-testing device includes: The pressure detection mechanism 1 includes a first motor 3 placed on both sides of the box body 2. The output shaft of the first motor 3 passes through the box body 2 and extends to the central rotating tooth 4. Both ends of the central rotating tooth 4 are meshed with a first gear plate 5 that moves in opposite directions. One end of the first gear plate 5 extends to the upper pressure plate 6, and the other end is connected to the lower pressure plate 7. The central shaft and the movable shaft 8 on the central rotating tooth 4 are connected by a conveyor belt 9. One end of the movable shaft 8 is mounted on the atomizer 10. The atomizer 10 is equipped with atomizing nozzles 11 arranged in a ring on the movable shaft 8. The atomizer 10 and the upper pressure plate 6 are connected by the first bracket 12. The outer wall of the conveyor belt 9 is equipped with a tensioning wheel 14 placed on the second bracket 13, and the top of the second bracket 13 extends to the upper pressure plate 6. A support platform 15 is provided between the atomizing nozzles 11 and placed on the inner wall of the box body 2.

[0023] The pressure detection mechanism 1 detects pressure damage by changing the air pressure, thus varying the pressure of the chip under different environments. The chip is placed on the support platform 15, and the first motor 3 is started, driving the central rotating gear 4 to rotate. Under the meshing transmission of the gears, the upper pressure plate 6 and lower pressure plate 7 at both ends move in a centered manner, compressing the volume in the sealed cavity and increasing the internal pressure. Simultaneously, the upper and lower pressure plates 6 and 7 convert their work into heat, further increasing the internal temperature of the sealed cavity. This simultaneously increases both the internal temperature and pressure of the sealed cavity. Furthermore, during the rotation of the central rotating gear 4, the transmission of the conveyor belt 9 further enhances its performance. The atomizing nozzle 11 on the movable shaft 8 can be rotated to evenly spray moisture onto the chip, thereby increasing the ambient humidity. Since the chips are distributed on the support platform 15 at different heights, a tensioning wheel 14 is provided on the conveyor belt 9 to effectively spray moisture onto the chips. Together with the first bracket 12 on the atomizer 10 and the second bracket 13 on the tensioning wheel 14, the power of the conveyor belt 9 can be effectively transmitted, and the atomizer 10 can be moved freely up and down, thereby effectively improving the applicability of the device. By changing the adjustment method of multiple variables, the functionality of the detection device is improved. The design is reasonable and the integrated performance is strong.

[0024] Specifically, the support platform 15 is used to place the chip. The chip's pressure is detected by adjusting the different air pressures in the air. The first motors 3 rotate synchronously, thereby driving the first gear plates 5 at the upper and lower ends to move synchronously in opposite directions. During the movement of the first gear plates 5, the upper pressure plate 6 and the lower pressure plate 7 can be driven to move in opposite directions and center at the same time. When the volume of the sealed cavity is compressed, the internal pressure increases. At the same time, the work done by the upper pressure plate 6 and the lower pressure plate 7 will be converted into heat, increasing the internal temperature of the box 2.

[0025] As the central shaft on the central rotating tooth 4 rotates, it transmits power to the movable shaft 8 via the conveyor belt 9. This allows the movable shaft 8 to drive the atomizing nozzle 11 to rotate and spray. When the first bracket 12 moves the atomizer 10 downward, the transmission distance of the conveyor belt 9 increases. To ensure the tension of the conveyor belt 9 during transmission, the second bracket 13 drives the tension wheel 14 to move downward synchronously. This allows the power of the conveyor belt 9 to be stably transmitted to the movable shaft 8, and enables the spraying of moisture onto the chips at different heights.

[0026] The upper pressure plate 6 and the lower pressure plate 7 are connected to the inner wall of the box body 2 by telescopic columns 16. The support platform 15 is equidistantly distributed on the inner wall of the box body 2 by means of detachable installation. The central rotating tooth 4 and the first gear plate 5 are both placed in the housing 17. The housing 17 is installed on the side wall of the box body 2 by means of locking and fixing by positioning pins.

[0027] The outer wall of the tensioning wheel 14 is provided with a rolling groove connected to the second bracket 13. The upper pressure plate 6 and the lower pressure plate 7 are connected with sliding grooves along the height direction of the inner wall of the box 2. A sealed cavity connected to the support platform 15 is formed between the upper pressure plate 6, the lower pressure plate 7 and the inner wall of the box 2. One end of the first gear plate 5 is connected with a limit block along the height direction of the side wall of the shell 17.

[0028] An integrated circuit chip self-testing device further includes a combustion test mechanism 18. The combustion test mechanism 18 includes crossbeams placed at both ends of a frame. One end of the crossbeams is connected to a spray gun 20 via a burner 19. A first support plate 21 is provided between the spray guns 20 and placed at the extension end of the base plate. A conical suction pipe 23 connected to a processing box 22 is provided above the first support plate 21.

[0029] Combustion testing is an experimental method that evaluates and rates the combustion performance of materials by simulating different combustion conditions. This method aims to detect key indicators such as flammability, smoke density, and combustion rate of materials, thereby effectively detecting the flammability of chips. This invention utilizes a purification mechanism to effectively treat smoke particles, avoiding environmental pollution.

[0030] During the operation of the combustion testing mechanism 18, the material properties are tested. When the exhaust gas particles generated by combustion can also be purified through the treatment box 22, environmental pollution can be avoided. The air pump 24 can transport the absorbed smoke particles to the activated carbon layer 38 of the treatment box 22 for filtration and purification. Moreover, according to the usage of the air pump 24, the contact area and time with the water are adaptively changed. When the power of the air pump 24 is high, more smoke particles are transported. At this time, the second motor 26 drives the small rotating gear 27 to rotate. By changing the transmission ratio, under the action of deceleration adjustment, the large rotating gear 28 is driven to rotate. Under the action of gear meshing transmission, the second gear plate 29 drives the first silencer plate 31 to move upward. Due to the elastic recovery action of the compression spring 34, the movable end on the second silencer plate 32 moves upward. This expands the internal volume of the silencing chamber, which can accommodate the large vibration amplitude noise generated when the air pump 24 is operating at high power, thus achieving a better noise reduction effect. At the same time, the third gear plate 30 drives the push plate 36 to move to the right, increasing the water level and extending the contact area and time with the smoke and dust. When the air pump 24 is operating at low power, the vibration amplitude of the noise is smaller, and there is relatively less smoke and dust. At this time, the movable end on the second silencing plate 32 moves downward, thereby reducing the internal volume of the silencing chamber. This can accommodate the smaller vibration amplitude noise generated when the air pump 24 is operating at low power. At the same time, the third gear plate 30 drives the push plate 36 to move to the left, decreasing the water level and shortening the contact area and time with the smoke and dust, accelerating the purification time, and improving work efficiency and environmental protection.

[0031] One end of the conical suction pipe 23 extends to the air pump 24 inside the processing box 22. The bottom of the air pump 24 is mounted on the second support plate 25. A second motor 26 is mounted on one end of the outer wall of the processing box 22. The output shaft of the second motor 26 extends to the small rotating gear 27. The outer wall of the small rotating gear 27 meshes with a large rotating gear 28. The two ends of the outer wall of the large rotating gear 28 are respectively meshed with a vertically distributed second gear plate 29 and a third gear plate 30. One end of the second gear plate 29 is mounted on the first silencer plate 31 through a bending rod 33.

[0032] Specifically, a second silencer plate 32 is connected to both sides of the bottom end of the first silencer plate 31. The movable end of the second silencer plate 32 is connected to the bottom end of the inner wall of the fixed part through a compression spring 34, and the movable end of the second silencer plate 32 abuts against the bottom of the first silencer plate 31. A silencer cavity is formed between the first silencer plate 31, the second silencer plate 32 and the bottom of the inner wall of the processing box 22. Both the first silencer plate 31 and the second silencer plate 32 are provided with silencer holes 35 that are adapted to them. The second silencer plate 32 is provided with a movable port that is connected to the conduit on the air pump 24. Guide grooves are connected to the side wall of the first silencer plate 31 and the second silencer plate 32 near the processing box 22.

[0033] The horizontal extension end of the third gear plate 30 is connected to the push plate 36. A water-filled cavity is formed between the push plate 36 and the fixed plate 37 on the inner wall of the treatment box 22. The air outlet on the cavity extends to the outside of the treatment box 22 through the activated carbon layer 38. One end of the conduit on the air pump 24 is installed on the U-shaped pipe 40 through the one-way flow guide assembly 39. The telescopic end on the U-shaped pipe 40 is connected to the inner wall of the push plate 36.

[0034] The duct is connected to a unidirectional flow guide component 39 in conjunction with a U-shaped tube 40, which not only prevents liquid backflow but also prevents gas backflow, thus playing a unidirectional adjustment role. The ratchet 44, in conjunction with the check pawl 45 movably connected to the vertical rod 46, allows the rotating shaft 41 to drive the guide plate 42 to rotate in one direction, thereby causing the dust to flow in one direction. Moreover, the arc groove 43 on the duct allows the guide plate 42 to rotate normally, preventing motion interference between structural components and ensuring stable dust transport, thereby improving the stability and safety of the device operation.

[0035] The unidirectional flow guide assembly 39 includes a rotating shaft 41 placed on a conduit. The outer wall of the rotating shaft 41 is provided with a flow guide plate 42 connected to the side wall of the conduit, and the bottom of the conduit is provided with an arc-shaped groove 43 connected to the flow guide plate 42. One end of the rotating shaft 41 is fixed on a ratchet 44, and the corner of the ratchet 44 abuts against and fits against a check pawl 45. One end of the check pawl 45 is connected to a vertical rod 46 by a rotatable connection.
