Description

Technical Field

[0001] This application relates to the field of industrial product conveying and cooling, and in particular to a cooling device for an oxygen sensor conveyor belt. Background Technology

[0002] As a key feedback component in the electronic fuel injection engine control system, the oxygen sensor plays a crucial role in controlling vehicle exhaust emissions and improving fuel combustion quality. The oxygen sensor monitors the oxygen concentration in the exhaust and sends a feedback signal to the vehicle's ECU (Engine Control Unit). The ECU then controls the amount of fuel injected by the injectors to ensure complete combustion, reducing fuel consumption while increasing engine power output. This maintains the air-fuel ratio near the theoretical value (14.7:1). Before leaving the factory, oxygen sensors undergo high-temperature testing to prevent functional failure. After testing, they are cooled to room temperature and then reheated for another functional test to ensure they meet the matching requirements of the ECU when installed in the vehicle.

[0003] Existing cooling methods include air cooling and water cooling. After cooling, operators mostly judge whether cooling is complete by the cooling time. However, the heat dissipation area of ​​existing cooling devices is small, resulting in low product cooling efficiency; and the distance between the cooling fan and the oxygen sensor is mostly fixed, which cannot adapt to the cooling requirements of different oxygen sensors; in addition, during on-site operation, the temperature of the oxygen sensor that needs to be cooled is high, and operators may accidentally touch it without knowing it, causing burns. Utility Model Content

[0004] To overcome the shortcomings of the prior art, this application provides a cooling device for an oxygen sensor conveyor belt. First, by evenly distributing several cooling fans on the heat sink, the heat dissipation efficiency is improved. Second, by adjusting the height adjustment mechanism, the distance between the cooling fans and the oxygen sensor is adjusted to ensure that the cooling requirements of different oxygen sensors are met. Finally, a heat dissipation protective cover is provided to prevent operators from accidentally touching the device during operation.

[0005] This application is achieved through the following technical solution:

[0006] A cooling device for an oxygen sensor conveyor belt includes a frame, which has a frame structure and two conveyor belts for conveying oxygen sensors are arranged in parallel on the frame. The oxygen sensors are placed on a support plate, the length of which is adapted to the distance between the two conveyor belts. A synchronizing rod is provided between the rotating wheels of the two conveyor belts to achieve synchronous movement of the two conveyor belts. At least one rotating wheel of the conveyor belt is powered by a drive device to rotate. A heat dissipation protective cover is provided above the conveyor belts. A heat dissipation plate is provided in the heat dissipation protective cover, and a plurality of cooling fans are evenly distributed on the heat dissipation plate. A height adjustment mechanism is provided inside the heat dissipation protective cover to adjust the distance between the cooling fans and the oxygen sensors.

[0007] By adopting the above technical solution, the conveyor belts can transport the load plate to the heat dissipation cover for heat dissipation. Furthermore, the two parallel conveyor belts, combined with the frame structure, create a hollow structure between them, providing more space for heat dissipation, increasing airflow, and improving heat dissipation efficiency. A synchronizing rod is installed between the rotating wheels of the two conveyor belts, ensuring that when one conveyor belt's wheel is driven by a drive unit, the synchronizing rod drives the rotating wheel of the other conveyor belt, achieving synchronous transport and preventing the oxygen sensor from tilting or falling. Several cooling fans are evenly distributed on the heat dissipation plate, allowing multiple fans to work together to improve heat dissipation efficiency. The height adjustment mechanism inside the heat dissipation cover can adjust the distance between the heat sink and the oxygen sensor to adapt to the cooling requirements of different oxygen sensors and optimize the heat dissipation effect.

[0008] Optionally, the drive device includes a drive motor and a transmission mechanism. The drive motor is fixed on the frame, and the transmission mechanism transmits the rotational torque of the drive motor to the rotating pulley of the conveyor belt.

[0009] By adopting the above technical solution, the drive motor is fixed on the frame, which can ensure that the output torque of the drive motor is stable and reliable, which is conducive to improving the stability of the conveyed items; the transmission mechanism transmits the torque of the drive motor to the rotating wheel of the conveyor belt, providing power for the movement of the conveyor belt.

[0010] Optionally, the transmission mechanism includes a driving wheel and a driven wheel. The driving wheel is fixed to the output end of the drive motor, and the driven wheel is connected to the rotating wheel of the conveyor belt through a connecting shaft. The driving wheel and the driven wheel are connected by a transmission belt.

[0011] By adopting the above technical solution, the driving wheel is fixed at the output end of the drive motor, which can directly convert the power of the motor into kinetic energy; the driving wheel and the driven wheel are connected by a transmission belt, which can buffer the impact force generated when the drive motor starts or stops, and play the role of a protective device.

[0012] Optionally, the heat dissipation protective cover has a U-shaped structure, including a top plate and side plates arranged parallel to the top plate, with the heat dissipation plate disposed between the two side plates.

[0013] By adopting the above technical solution, the heat dissipation protective cover has a U-shaped structure, which can provide space for airflow during heat dissipation and play a certain protective role; the top plate can isolate the cooling fan from the external space, prevent operators from touching the cooling fan, and ensure personnel safety; the side plates arranged on the top plate provide a stable foundation for the arrangement of the heat dissipation plate.

[0014] Optionally, the height adjustment mechanism includes several sliding grooves opened vertically along the side plate; the heat sink is provided with threaded holes that are adapted to the sliding grooves on the side edge, and locking bolts adapted to the opening of the sliding grooves are threadedly connected in the threaded holes.

[0015] By adopting the above technical solution, several grooves are opened on the side plate, which can change the distance between the cooling fan and the oxygen sensor to adapt to different cooling requirements. The height adjustment mechanism adopts a groove opened in the vertical direction. For oxygen sensors with different cooling requirements or specifications, the heat dissipation efficiency can be improved by adjusting the distance between the cooling fan and the oxygen sensor. When the cooling fan is in the appropriate position, the threaded hole on the heat sink plate, together with the locking bolt that matches the opening of the groove, can fix the position of the heat sink plate and ensure that the cooling fan does not move during the cooling process.

[0016] Optionally, the heat dissipation shield has a baffle plate in the opening and several ventilation holes adapted to the cooling fan on the top plate.

[0017] By adopting the above technical solution, a baffle is set in the opening of the heat dissipation protective cover, which can not only prevent wind energy from spreading and allow more airflow to blow towards the oxygen sensor to improve heat dissipation efficiency, but also prevent the operator from taking out the oxygen sensor before it has cooled to a suitable temperature; the top plate is provided with several ventilation holes adapted to the cooling fan so that the wind can carry the heat of the oxygen sensor out of the heat dissipation protective cover, preventing the temperature inside the heat dissipation protective cover from being too high and affecting normal operation.

[0018] Optionally, a flexible coupling is provided between the synchronizing rod and the rotating wheel of the conveyor belt.

[0019] By adopting the above technical solutions, the flexible coupling can buffer the impact and vibration generated during the start-up, stop or operation of the transmission belt. The flexible coupling can absorb energy through its own deformation, reduce the damage of impact to the transmission belt and the synchronization rod, and extend the service life of the device.

[0020] Optionally, mounting rods are provided on both sides of the frame, and mounting grooves are provided on the sides of the mounting rods along the length direction, with the heat dissipation protective cover fixed in the mounting grooves.

[0021] By adopting the above technical solution, the mounting groove provided on the side of the mounting rod can fix the heat dissipation protective cover and prevent the heat dissipation protective cover from shaking during operation. The mounting groove is provided along the length of the side of the mounting rod to facilitate the adjustment of the position of the heat dissipation protective cover.

[0022] Optionally, the frame is provided with a guide rod for guiding the movement of the load plate. The guide rod has an L-shaped structure and includes an isolation part and a guide part. The end of the guide part is provided with a guide bevel, and the isolation part is located below the conveyor belt transport section.

[0023] By adopting the above technical solution, the guide section can prevent the carrier plate from falling or shifting during the conveying process, ensuring that the carrier plate can transport the oxygen sensor in a predetermined direction. The guide bevel at the end of the guide section can play a guiding role, smoothly changing the movement direction of the carrier plate when it enters the conveyor belt, ensuring the accuracy of the material transport direction; the isolation section can play a heat insulation role, extending the service life of the device.

[0024] In summary, this application includes at least one of the following beneficial technical effects:

[0025] 1. This application achieves multiple cooling fans working together by evenly arranging several cooling fans on the heat sink, thereby increasing the heat dissipation area; the two parallel transmission belts, together with the frame structure, provide more space for heat dissipation, increase airflow, and improve heat dissipation efficiency.

[0026] 2. This application uses a U-shaped heat dissipation protective cover to prevent operators from accidentally touching the oxygen sensor during the cooling process;

[0027] 3. This application improves cooling efficiency by setting a height adjustment mechanism to maintain a suitable distance between the cooling fan and the oxygen sensor.

[0028] 4. This application, by setting a synchronizing rod between the rotating wheels of the two conveyor belts and cooperating with the elastic coupling between the synchronizing rod and the rotating wheels of the conveyor belts, can enable the elastic coupling to absorb energy through its own deformation when the drive motor is turned on or off, so that the conveyor belt continues to move for a period of time due to inertia, thus extending the service life of the device.

[0035] The technical solutions of various embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0036] Example 1

[0037] Reference Figures 1-2 This application discloses a cooling device for an oxygen sensor conveyor belt 3, comprising a frame 1, the frame 1 having a frame structure, and two conveyor belts 3 for conveying oxygen sensors arranged in parallel on the frame 1; the oxygen sensor is placed on a carrying plate 5, the length of the carrying plate 5 being adapted to the distance between the two conveyor belts 3; a synchronizing rod 4 is provided between the rotating wheels 33 of the two conveyor belts 3 to realize the synchronous movement of the two conveyor belts 3; at least one rotating wheel 33 of the conveyor belt 3 is powered by a driving device 2 to rotate; a heat dissipation protective cover 6 is provided above the conveyor belts 3; a heat dissipation plate 61 is provided in the heat dissipation protective cover 6, a plurality of cooling fans 62 are evenly distributed on the heat dissipation plate 61, and a height adjustment mechanism 7 is provided inside the heat dissipation protective cover 6, the height adjustment mechanism 7 being used to adjust the distance between the cooling fans 62 and the oxygen sensor.

[0038] Specifically, refer to Figure 1A cooling device for an oxygen sensor conveyor belt 3 includes a frame 1, which is a frame structure made of stainless steel. Mounting rods 12 are provided on both sides of the frame 1, and mounting grooves 121 are provided along the length of the mounting rods 12. A heat dissipation protective cover 6 is connected to the mounting grooves 121. The heat dissipation protective cover 6 is a U-shaped structure made of stainless steel. The U-shaped heat dissipation protective cover 6 can prevent operators from accidentally touching the oxygen sensor during device operation, thus preventing injury or death. A heat dissipation plate 61 is provided inside the heat dissipation protective cover 6, and several cooling fans 62 are evenly arranged on the heat dissipation plate 61. The cooling fans 62 are evenly arranged along the surface of the heat dissipation plate 61 to provide airflow support for heat dissipation of the oxygen sensor. In addition, a number of ventilation holes 631 adapted to the cooling fans 62 are provided on the top plate 63 of the heat dissipation protective cover 6 to prevent the temperature inside the heat dissipation protective cover 6 from becoming too high.

[0039] Reference Figures 1-2 In this embodiment, a driving device 2 drives the rotating wheel 33 of the conveyor belt 3. The conveyor belt 3 closer to the driving device 2 is the first conveyor belt 31, and the conveyor belt 3 farther away from the driving device 2 is the second conveyor belt 32. The driving device 2 includes a driving motor 21 and a transmission mechanism 22. The driving motor 21 is fixed on the frame 1. After the driving motor 21 is turned on, the driving motor 21 transmits the rotational torque to the driving wheel 221 connected to the output end of the driving motor 21. The driving wheel 221 drives the driven wheel 222 to rotate through the transmission belt 223, and then drives the first conveyor belt 31 to move through the connecting shaft 42. At this time, the rotating wheel 33 of the first conveyor belt 31 drives the second conveyor belt 32 to transport the oxygen sensor at the same speed through the synchronizing rod 4, so as to achieve the same speed of transporting the carrying plate 5 on both conveyor belts 3 while ensuring the cooling effect. The length of the carrying plate 5 is adapted to the distance between the two conveyor belts 3 to ensure that the oxygen sensor can be placed and transported stably.

[0040] Reference Figure 2 On the synchronizing rod 4, near the two conveyor belts 3, there is a flexible coupling 41. The flexible coupling is made of rubber material with elasticity and shock absorption properties. The flexible coupling 41 is located between the rotating pulleys 33 of the two conveyor belts 3. When the drive motor 21 starts, the rotating pulley 33 of the conveyor belt 3 closest to the drive motor 21 rotates first, which causes the flexible coupling 41 to undergo elastic deformation, absorbing part of the energy transmitted by the rotating pulley 33, providing a buffer for the conveyor belt 3, reducing the wear caused by the start or stop of the drive motor 21 on the device, and extending the service life of the device.

[0041] Reference Figure 3The height adjustment mechanism 7 includes several vertically oriented grooves 71 on the side plate 65. The heat sink 61 has threaded holes 611 on its side edge that fit the grooves 71. Locking bolts 72, which fit the opening of the grooves 71, are threaded into the threaded holes 611. Loosening the locking bolts 72 allows the heat sink 61 to move up and down along the grooves 71, adjusting the distance between the heat sink 61 and the oxygen sensor. Tightening the locking bolts 72 ensures the heat sink 61 is threadedly connected to the grooves 71, preventing the cooling fan 62 from shaking during operation.

[0042] The implementation principle of this embodiment is as follows: Several cooling fans 62 evenly arranged on the heat sink 61 can provide the air required for cooling the device; the drive motor 21 transmits the rotational torque to the drive wheel 221 connected to the output end of the drive motor 21. The drive wheel 221 drives the driven wheel 222 to rotate through the transmission belt 223. The driven wheel 222 drives the rotating wheel 33 of the first conveyor belt 31 to rotate through the connecting shaft 42. The rotating wheels 33 of the two conveyor belts 3 maintain the same speed through the synchronizing rod 4, so as to realize the smooth transport of the carrying plate 5; after the carrying plate 5 enters the heat dissipation protective cover 6, the U-shaped heat dissipation protective cover 6 can prevent the operator from accidentally touching it and protect the safety of the personnel; the threaded hole 611 provided on the side edge of the heat sink 61, together with several sliding grooves 71 opened in the vertical direction on the side plate 65, can realize that when the heat sink 61 is adjusted to a suitable height, the locking bolt 72 passes through the sliding groove 71 and is threaded together with the heat sink 61, so as to improve the heat dissipation efficiency by adjusting the distance between the heat sink 61 and the oxygen sensor.

[0043] Example 2

[0044] refer to Figure 4 The difference between this embodiment and the first embodiment is that a baffle plate 64 is provided at the front and back of the opening of the heat dissipation protective cover 6. The baffle plate 64, together with the U-shaped heat dissipation protective cover 6, enables the heat dissipation protective cover 6 to better gather the air generated by the cooling fan 62, which can prevent the air energy from spreading and allow more airflow to blow towards the oxygen sensor, thereby improving the heat dissipation efficiency. In addition, the baffle plate 64 can also prevent the operator from accidentally touching the oxygen sensor during the operation of the device, which would affect the cooling effect.

[0045] refer to Figure 5 The frame 1 is equipped with a guide rod 8 for guiding the movement of the load plate 5. The guide rod 8 has an L-shaped structure and includes an isolation part 81 and a guide part 82. When the load plate 5 is placed on the frame 1, the guide bevel 821 provided on the guide part 82 causes the load plate 5 to transport the oxygen sensor in a predetermined direction. In addition, the upper surface of the isolation part 81 is in contact with the lower surface of the conveyor belt 3, which can play a role in heat insulation and reduce the impact of the heat generated by the conveyor belt 3 during operation on the device.

[0046] The implementation principle of this embodiment is as follows: The cooling fan 62, together with the U-shaped heat dissipation protective cover 6 and the baffle plate 64 on the heat dissipation protective cover 6, prevents the air generated by the cooling fan 62 from directly entering the external space when passing through the baffle plate 64. This makes the air inside the heat dissipation protective cover 6 more concentrated and blown towards the oxygen sensor, improving the heat dissipation efficiency. In addition, the baffle plate 64 can also prevent the operator from accidentally touching the oxygen sensor during the operation of the device, which would affect the cooling effect. The guide bevel 821 at the end of the guide part 82 of the L-shaped guide rod 8 can smoothly change the movement direction of the carrying plate 5 when it enters the conveyor belt 3, ensuring the accuracy of the transport direction of the carrying plate 5. The isolation part 81 isolates the belt of the conveyor belt 3 from the frame 1, thereby playing a role in heat insulation.

[0047] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this application, and are not intended to limit them. Although this application has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features therein. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the technical solutions of the embodiments of this application.
