Abstract
Description
Technical Field
[0001] This invention relates to the field of temperature and humidity measurement of items, and more specifically, to a device for mass-producing temperature and humidity sensors. Background Technology
[0002] Temperature and humidity meter calibration refers to the calibration or verification of the measurement accuracy of temperature and humidity meters through professional means to ensure that the data provided during use meets national or industry standards.
[0003] The current measurement operation of temperature and humidity sensors involves placing the sensor in an environmental chamber, setting the chamber's temperature and humidity, and then performing the measurement. However, after the measurement is completed and the chamber door is opened, the temperature difference between the inside and outside of the chamber is significant, especially during low-temperature measurements in summer. When the chamber is opened and the shelf is removed, the cool outside air causes water droplets to form on the shelf surface. This water droplets can then easily drip onto the temperature and humidity sensor during subsequent measurements. Contact with water can cause the sensor's readings to spike, leading to measurement errors. Summary of the Invention
[0004] This invention provides a device for mass-producing temperature and humidity sensors, solving the technical problem in related technologies where condensation droplets on the surface of the shelf fall onto the temperature and humidity sensor due to the temperature difference between the inside and outside of the environmental chamber, causing measurement deviations.
[0005] This invention provides a device for mass-producing temperature and humidity sensors, including a housing and a door that is hinged to the front end of the housing. A frame is placed inside the housing, and brackets are fixedly connected to both sides of the frame. A shelf is placed on the upper end of the bracket, and a PCB board is electrically connected to the upper end of the shelf. A temperature and humidity sensor is inserted into the upper end of the PCB board. A moisture-proof component is provided between adjacent brackets to prevent condensation from dripping onto the temperature and humidity sensor. The moisture-proof component includes a front beam and a rear beam fixedly connected to the front and rear ends of the bracket, and a multi-functional plate is rotatably connected between the front beam and the rear beam. A first gear corresponding to the multi-functional plate is rotatably connected inside the front beam, and a rack meshing with the first gear is movably connected to the lower end of the front beam. A second gear is rotatably connected to the middle section of the front beam, and a push rod passes through the middle of the second gear. A spiral groove is opened on the surface of the push rod, and a guide block adapted to the spiral groove is provided inside the second gear.
[0006] As a further optimization of the present invention, a force-bearing block is fixedly connected to the front end of the push rod, the second gear meshes with the rack, and a first spring is sleeved on the outside of the push rod between the force-bearing block and the front beam, and the elastic force of the first spring is greater than the sum of the resistances encountered when the multiple multi-functional plates rotate.
[0007] As a further optimization of the present invention, the upper end of the bracket is provided with a corrugated groove, the lower end of the shelf is rotatably fitted with a roller adapted to the corrugated groove, and the multifunctional plate is inclined with the front higher and the back lower.
[0008] As a further optimization of the present invention, a wind equalization component is provided between the multifunctional plate and the front beam and the rear beam. The wind equalization component includes a push plate movably connected to the inside of the front beam. A connecting shaft slides through the inside of the multifunctional plate, and a limit block is fixedly connected to the surface of the connecting shaft. The push plate is fixedly connected to the outer front end of the connecting shaft. The front end of the connecting shaft slides through the inside of the first gear, and a limit groove is formed on the inner wall of the through hole of the first gear.
[0009] As a further optimization of the present invention, the opening edge of the limiting groove and the edge of the through hole of the first gear are both rounded, and the rear end of the connecting shaft slides through the rear beam.
[0010] As a further optimization of the present invention, an electric telescopic device is fixedly connected to one side of the rear beam, and the output end of the electric telescopic device extends through the interior of the rear beam and is fixedly connected to a toggle rod. The bottom of the toggle rod is provided with a toggle groove corresponding to the multi-functional plate.
[0011] As a further optimization of the present invention, the first gear and the second gear have the same specifications. The guide block on the inner wall of the second gear behind the push rod can drive the second gear to rotate a quarter turn after sliding along the inside of the spiral groove. The surface of the push rod is provided with a straight groove that communicates with the spiral groove.
[0012] As a further optimization of the present invention, a plug-in assembly is provided between the bracket and the front beam. The plug-in assembly includes a plug hole opened at the bottom of the shelf. A mounting groove is opened at the top of the bracket, and a plug is movably connected inside the mounting groove. A sliding plate that is slidably adapted to the mounting groove is fixedly connected to the outside of the plug. A second spring is fixedly connected between the bottom of the sliding plate and the mounting groove. A slot is opened on the inner side of the bracket, and an integrally formed extension is provided on one side of the rack.
[0013] As a further optimization of the present invention, the bottom of the plug is inclined, and the rack can drive the extension to be inserted into the mounting groove from the slot after sliding. The elastic force of the second spring is greater than the insertion friction between the plug and the socket, and the plug, the socket and the PCB board are electrically connected.
[0014] The beneficial effects of this invention are as follows: 1. The device for mass-producing temperature and humidity sensors described in this invention utilizes multiple multifunctional plates rotated to a horizontal state and spliced together to form a water-receiving plate. Therefore, after the measurement is completed, during the process of removing the measured temperature and humidity sensors and installing new temperature and humidity sensors, water droplets formed by condensation on the surface of the plates will drip onto the water-receiving plate and flow through the inclined surface of the water-receiving plate into the interior of the rear beam for collection. This avoids the measurement deviation caused by condensation water dripping onto the surface of the temperature and humidity sensors during the replacement process.
[0015] 2. The device for mass-producing temperature and humidity sensors described in this invention uses a toggle lever with a toggle groove at the lower end engaging with a limiting block to cause the limiting block to swing. This causes the multi-functional plate to swing, resulting in a change in airflow direction when the air blown from the top of the housing passes through the air duct formed between adjacent multi-functional plates. This increases the air outlet area, allowing the air blown from the outlet to flow quickly to the lower layer, improving the ventilation effect inside the housing, reducing dead zones in the housing, ensuring uniform temperature and humidity inside the housing, and thus improving the accuracy of the temperature and humidity sensor measurements.
[0016] 3. The device for mass measurement of temperature and humidity sensors described in this invention triggers automatic plug insertion and removal by opening and closing the door, which facilitates quick removal of the shelf and improves the efficiency of mass measurement of temperature and humidity sensors.

[0019] The subject matter described herein will now be discussed with reference to exemplary embodiments. It should be understood that these embodiments are discussed only to enable those skilled in the art to better understand and implement the subject matter described herein, and changes may be made to the function and arrangement of the elements discussed without departing from the scope of this specification. Various processes or components may be omitted, substituted, or added as needed in the examples. Furthermore, features described in some examples may be combined in other examples.
[0020] like Figures 1 to 10 As shown in the figure, the device for mass measurement of temperature and humidity sensors according to an embodiment of the present invention includes a housing 10 and a door 11 connected to its front end by a hinge. A frame 12 is placed inside the housing 10, and brackets 13 are fixedly connected to both sides of the frame 12. A shelf 14 is placed on the upper end of the bracket 13, and a PCB board 15 is electrically connected to the upper end of the shelf 14. A temperature and humidity sensor 16 is inserted into the upper end of the PCB board 15. A moisture-proof component 20 is provided between adjacent brackets 13 to prevent condensation from dripping onto the temperature and humidity sensor 16. The moisture-proof component 20 includes a front beam 21 and a rear beam 22 fixedly connected to the front and rear ends of the bracket 13, and a multi-functional plate 23 is rotatably connected between the front beam 21 and the rear beam 22. A first gear 24 corresponding to the multi-functional plate 23 is rotatably connected inside the front beam 21, and a rack 25 meshing with the first gear 24 is movably connected to the lower end of the front beam 21. A second gear 26 is rotatably connected to the middle section of the front beam 21, and a push rod 28 passes through the middle of the second gear 26. A spiral groove 29 is opened on the surface of the push rod 28. A guide block adapted to the spiral groove 29 is provided inside the second gear 26. The first gear 24 and the second gear 26 have the same specifications. After the push rod 28 and the guide block on the inner wall of the second gear 26 slide along the spiral groove 29, they can drive the second gear 26 to rotate a quarter turn. The front end of the push rod 28 is fixedly connected to a force-bearing block 27. The second gear 26 meshes with the rack 25. A first spring 210 is sleeved on the outside of the push rod 28 between the force-bearing block 27 and the front beam 21. The elastic force of the first spring 210 is greater than the sum of the resistances encountered when the multiple multifunctional plates 23 rotate. A corrugated groove 211 is opened at the upper end of the bracket 13. A roller 212 adapted to the corrugated groove 211 is rotatably fitted at the lower end of the shelf 14. The multifunctional plate 23 is inclined with the front higher than the back.
[0021] It should be noted that, firstly, the temperature and humidity sensors 16 are inserted into the PCB board 15 in a 4*6 arrangement. Then, the four PCB boards 15 with the temperature and humidity sensors 16 inserted are fixed onto the shelf 14. Next, the shelf 14 is overlapped with two adjacent brackets 13. Then, the entire frame 12 is placed inside the enclosure 10 and the door 11 is closed. The temperature and humidity values inside the enclosure 10 are then set, and the temperature and humidity sensors 16 inside the enclosure 10 are calibrated. It should be noted that a wire is led out from each shelf 14, and these wires are connected together and led out through the external interface of the enclosure 10. Each PCB board 15 has a control chip, and through a serial port expansion chip, the main control chip and the sensors can be connected. Point-to-point communication eliminates the need for address identification during communication. A host computer tool software is installed on the computer. When data from each temperature and humidity sensor 16 needs to be obtained, the operator only needs to click "Get Data" in the tool software. The software will automatically send a command to retrieve the data from each temperature and humidity sensor 16 on each PCB board 15. After the data is obtained, the software automatically generates an Excel-format record file containing the ID of the temperature and humidity sensor 16 and the corresponding temperature and humidity values. No manual recording is required, thus enabling large-scale measurement of the temperature and humidity sensors 16. At the same time, if a greenhouse sensor 16 fails to measure, the corresponding temperature and humidity sensor 16 can be quickly located by its location number, saving time. To prevent condensation from dripping onto the temperature and humidity sensor 16 due to temperature differences and causing measurement data deviations, a moisture-proof component 20 is installed. Initially, multiple multi-functional panels 23 are horizontally arranged to form a complete, sloping water-receiving plate, higher in the front and lower in the back. When the door 11 is closed, it contacts the force-bearing block 27 on the front beam 21 and applies a pushing force. The force-bearing block 27 then pushes the push rod 28 to move. The push rod 28 acts as a guide block on the inner wall of the second gear 26, creating a relative displacement along the spiral groove 29 on its surface, thus rotating the second gear 26. The rotation of the second gear 26 then moves the rack 25, which in turn rotates the first gear 24. Since the second gear 26 and the first gear 24 are of the same specification, they rotate synchronously by a quarter turn, causing the multi-functional panels 23 to rotate ninety degrees, resulting in a vertically aligned state. The multi-functional panels 23 are separated, and the separated multi-functional panels 23 form an air duct, which does not affect the air circulation inside the box 10 during measurement, ensuring uniform temperature and humidity inside the box 10. When the measurement is completed and the box door 11 is opened, the force block 27 is no longer resisted by the box door 11. Under the action of the first spring 210, the force block 27 is pushed to drive the push rod 28 to reset. At this time, the second gear 26 drives the first gear 24 to rotate and reset through the rack 25, so that the multiple multi-functional panels 23 rotate to a horizontal state and splice into a water receiving plate. Therefore, after the measurement is completed, during the process of removing the temperature and humidity sensor 16 that has completed the measurement and installing the new temperature and humidity sensor 16, the water droplets formed by condensation on the surface of the shelf 14 will drip onto the water receiving plate and flow through the inclined surface of the water receiving plate to the interior of the rear beam 22 for collection, avoiding the condensation water droplets falling onto the surface of the temperature and humidity sensor 16 during the replacement of the temperature and humidity sensor 16 and causing measurement deviation. In addition, when replacing the temperature and humidity sensor 16, the shelf 14 needs to be pulled out from the frame 12 to the outside of the box 10. During the pulling process, the roller 212 at the bottom of the shelf 14 will intermittently enter and disengage from the corrugated groove 211 opened on the bracket 13, so that the shelf 14 will bounce and vibrate during the pulling out and pushing in. The bounce and vibration of the shelf 14 can make the condensate water attached to its surface drip off quickly, so that there is no condensate water attached to the surface of the shelf 14 when the next batch of measurement is performed. This ensures that no condensate water drips onto the temperature and humidity sensor 16 after the multi-functional board 23 is separated, thus ensuring the accuracy of the temperature and humidity sensor 16 measurement.
[0022] like Figure 3 , Figure 12 and Figure 13As shown, a wind equalization assembly 30 is provided between the multi-functional plate 23, the front beam 21, and the rear beam 22. The wind equalization assembly 30 includes a push plate 36 movably connected to the inside of the front beam 21. A connecting shaft 34 slides through the inside of the multi-functional plate 23, and a limit block 35 is fixedly connected to the surface of the connecting shaft 34. The push plate 36 is fixedly connected to the outer front end of the connecting shaft 34. The front end of the connecting shaft 34 slides through the inside of the first gear 24, and a limit groove 37 is provided on the inner wall of the through hole of the first gear 24. The opening edge of the limiting groove 37 and the edge of the through hole of the first gear 24 are both rounded. The rear end of the connecting shaft 34 slides through the rear beam 22. An electric telescopic device 31 is fixedly connected to one side of the rear beam 22, and the output end of the electric telescopic device 31 extends into the interior of the rear beam 22 and is fixedly connected to a toggle rod 32. The bottom of the toggle rod 32 is provided with a toggle groove 33 corresponding to the multi-functional plate 23. The surface of the push rod 28 is provided with a straight groove 38 that communicates with the spiral groove 29.
[0023] It should be noted that, in order to ensure the uniformity of temperature and humidity inside the enclosure 10, an air outlet is set at the top of the enclosure 10 and an air return outlet is set at the bottom of the enclosure 10. However, since multiple layers of shelves 14 are set on the frame 12, and four PCB boards 15 are set on each shelf 14, and multiple temperature and humidity sensors 16 are also installed on the PCB boards 15, the air circulation inside the enclosure 10 will be obstructed, resulting in deviations in temperature and humidity in different areas inside the enclosure 10, which will affect the accuracy of the temperature and humidity sensors 16. Based on this, a connecting shaft 34 is used to connect the multi-functional plate 23 to the front beam 21 and the rear beam 22. A limiting block 35 is set on the surface of the connecting shaft 34 so that the connecting shaft 34 can slide inside the multi-functional plate 23 and drive the multi-functional plate 23 to rotate. In the initial state, the part of the connecting shaft 34 with the limiting block 35 at the front end is inserted into the first gear 24 and engages with the limiting groove 37 on the inner wall of the first gear 24. At this time, the rotation of the first gear 24 can drive the multi-functional plate 23 to rotate synchronously. However, as the push rod 28 continues to move, after the guide block on the inner wall of the second gear 26 slides from the spiral groove 29 into the straight groove 38, the push rod 28 pushes the push plate 36 to move, so that the push plate 36 drives the connecting shaft 34 to slide and the part of the connecting shaft 34 with the limiting block 35 at the front end disengages from the first gear 24. At this time, the connecting shaft 34 can rotate relative to the first gear 24. Then, the electric telescopic device 31 drives the actuating rod 32 to reciprocate, so that the actuating groove 33 at the lower end of the actuating rod 32 is engaged with the limiting block 35. The upper limit block 35 swings, which in turn causes the multi-functional plate 23 to swing. When the air blown out from the top of the box 10 passes through the air duct formed between the adjacent multi-functional plates 23, the swing of the multi-functional plate 23 changes the flow direction, thereby increasing the air outlet area. This allows the air blown out from the air outlet to flow quickly to the lower layer, improving the ventilation effect inside the box 10, reducing the circulation dead angle inside the box 10, ensuring uniform temperature and humidity inside the box 10, and thus improving the accuracy of the temperature and humidity sensor 16 measurement. After the measurement is completed, the box door 11 is opened, and the push rod 28 and push plate 36 are pulled back to their original positions under the action of the first spring 210. This causes the part of the connecting shaft 34 with the limit block 35 at the front end to re-insert into the inside of the first gear 24. The inner wall of the first gear 24 has multiple sets of limit grooves 37, and the opening edge of the limit groove 37 and the edge of the through hole of the first gear 24 are rounded, so that the limit block 35 on the surface of the connecting shaft 34 can be smoothly inserted back into the limit groove 37.
[0024] like Figure 6 , Figure 9 , Figure 11 and Figure 14 As shown, a plug-in assembly 40 is provided between the bracket 13 and the front beam 21. The plug-in assembly 40 includes a plug hole 41 opened at the bottom of the shelf 14. A mounting groove 42 is opened at the top of the bracket 13. A plug 44 is movably connected inside the mounting groove 42. A sliding plate 43 that is slidably adapted to the mounting groove 42 is fixedly connected to the outside of the plug 44. A second spring 45 is fixedly connected between the bottom of the sliding plate 43 and the mounting groove 42. A slot 46 is opened on the inner side of the bracket 13. An integrally formed extension 47 is provided on one side of the rack 25. The bottom of the plug 44 is inclined. After the rack 25 slides, it can drive the extension 47 to be inserted into the mounting groove 42 from the slot 46. The elastic force of the second spring 45 is greater than the insertion friction between the plug 44 and the socket 41. The plug 44, the socket 41 and the PCB board 15 are electrically connected.
[0025] It should be noted that, since the shelf 14 is equipped with wiring connections during batch metering, when the temperature and humidity sensor 16 is replaced after metering, the shelf 14 needs to be pulled out. However, the wiring connections will affect the removal of the shelf 14, requiring manual plugging and unplugging of the connectors, which is very time-consuming and laborious. Based on this, when the door 11 is closed, the push rod 28 moves and drives the second gear 26 to rotate. The rotation of the second gear 26 drives the rack 25 to move, so that the extension 47 at the end of the rack 25 is inserted into the mounting groove 42 through the slot 46. As the extension 47 is inserted, the plug 44 is pushed upward by the inclined surface at the bottom of the plug 44 and inserted into the insertion hole 41 at the bottom of the shelf 14 to complete the connection. When the door 11 is opened, the rack 25 returns to its original position and pulls the extension 47 out of the mounting groove 42. At this time, under the action of the second spring 45, the sliding plate 43 pulls the plug 44 to return to its original position and disengage from the insertion hole 41, disconnecting the connection. The plug 44 is automatically plugged and unplugged by opening and closing the door, which facilitates the quick removal of the shelf 14 and improves the working efficiency of the batch measurement of the temperature and humidity sensor 16.
