Description

Technical Field

[0001] This invention relates to the field of sensor manufacturing technology, and in particular to a production equipment for a high-precision temperature sensor. Background Technology

[0002] A temperature sensor is a sensor that detects changes in temperature and converts them into a usable output signal. During the production of temperature sensors, they need to be tested. Only sensors that pass the test can proceed to the next production step. In the production process, the temperature sensor is often tested to detect the corresponding output signal when it senses different temperatures. The output signal is then used to determine whether the temperature sensor meets the requirements.

[0003] In existing technologies, temperature sensor production equipment often only performs simple one-sided temperature accuracy testing during the production process. It fails to detect the timely response of the temperature sensor to different temperatures, reducing the efficiency of temperature sensor performance testing and leading to the production of substandard sensors. Furthermore, the repeated separation and contact between the temperature sensor and the testing device during temperature sensing can cause the temperature environment created by the testing device to come into contact with the outside environment, resulting in heat loss. This increases the energy consumption for restoring heat within the testing device, further reducing the temperature sensor's detection efficiency and impacting production progress. Summary of the Invention

[0004] The purpose of this invention is to address the shortcomings of existing high-precision temperature sensor production equipment, which cannot detect the timely sensing of different temperatures by the temperature sensor, thus reducing the efficiency of temperature sensor performance detection. Therefore, this invention proposes a high-precision temperature sensor production equipment.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: a production equipment for a high-precision temperature sensor, comprising a testing bench, wherein a control console is mounted on the side of the testing bench, and further comprising:

[0006] The installation mechanism includes a connecting platform, which is fixedly connected to the top of the test platform. A first electric rod is installed at the bottom of the connecting platform. A fixed plate and a limiting plate are fixedly connected to the output end of the first electric rod. The limiting plate is located below the fixed plate. A lifting groove is provided on the top of the test platform. The limiting plate and the lifting groove are coaxially slidably engaged. Multiple mounting grooves are provided on the limiting plate. Temperature sensors are inserted into the mounting grooves.

[0007] The testing mechanism includes a lifting and rotating assembly connected to the bottom of the testing platform. The output end of the lifting assembly extends into a lifting groove and is connected to a temperature measuring disk. The temperature measuring disk is coaxially slidably connected within the lifting groove. A sliding groove is coaxially formed on the temperature measuring disk, and multiple temperature measuring chambers are connected to the sliding groove. The bottom ends of multiple temperature sensors are coaxially clearance-fitted with the multiple temperature measuring chambers and coaxially rotate with the inside of the sliding groove. Heating blocks are installed inside each temperature measuring chamber, and the multiple heating blocks are used to apply different temperatures to the multiple temperature measuring chambers. Each of the multiple temperature sensors is detachably electrically connected to a data connection device. The top ends of the multiple data connection devices penetrate the fixed disk and the connecting platform and are electrically connected to the control console.

[0008] Preferably, the side of the fixed disk is fixedly connected with multiple engaging components, and the top of the test platform is fixedly connected with multiple engaging blocks, each of the engaging blocks corresponding to and engaging with the engaging components.

[0009] Preferably, the lifting and rotating assembly includes a first motor, which is installed inside the bottom of the test bench. The output end of the first motor extends through into the lifting groove and is equipped with a second electric rod. The output end of the second electric rod is fixedly connected to the temperature measuring plate.

[0010] Preferably, the multiple temperature measuring chambers are arranged in a circular array with the temperature measuring plate as the center.

[0011] Preferably, the temperature measuring plate is made of fiber ceramic matrix composite material.

[0012] Preferably, a second motor is installed at the bottom of the temperature measuring chamber, and a base plate is coaxially fixedly connected to the output end of the second motor. The base plate is coaxially slidably connected inside the temperature measuring chamber, and a heat insulation plate and a heat conduction plate are fixedly connected to the top. The heat insulation plate and the heat conduction plate are coaxially clearance-fitted, and the heat insulation plate is located outside the heat conduction plate. The heating block is coaxially clearance-located between the heat insulation plate and the heat conduction plate. Both sides of the heat insulation plate and the heat conduction plate are provided with through slots for the temperature sensor to rotate through.

[0013] Preferably, the heating block is fixedly connected to the temperature measuring plate by a bracket that passes over the insulation plate, and the heating block is located inside the temperature measuring chamber and is not on the track of the sliding groove.

[0014] Preferably, the temperature-conducting plate has a hollow structure.

[0015] Preferably, the sliding groove located between two adjacent temperature measuring chambers has a groove connected to its side. A third electric rod is installed in the groove. A heat insulation block is fixedly connected to the output end of the third electric rod. The heat insulation block is slidably and sealed in the groove, and moves into the sliding groove and seals the sliding groove when the output end of the third electric rod extends.

[0016] Preferably, the sides of the insulation block are made of heat-insulating material, and the middle part is made of heat-absorbing material.

[0017] Compared with the prior art, the advantages of the present invention are as follows:

[0018] 1. This invention, by setting up a testing mechanism, drives the temperature measuring disk to move up and down and rotate by lifting and rotating components, so that the temperature sensor can make contact and cooperate with the test chambers of different temperatures on the temperature measuring disk one by one. Thus, while testing the temperature accuracy of the temperature sensor, it can quickly improve the timeliness of the temperature sensor's response feedback when the temperature sensor passes through the test chambers of different temperatures, greatly improving the efficiency of the temperature sensor's detection performance.

[0019] 2. By setting up a testing mechanism, the present invention provides a sliding groove on the testing plate for the temperature sensor to rotate directly. This eliminates the need to separate the temperature measuring plate from the temperature sensor before rotation. The temperature sensor can move directly from one testing chamber to the next adjacent testing chamber via the sliding groove, effectively avoiding heat loss within the testing chamber, reducing the energy consumption for restoring heat within the testing chamber, and improving the detection efficiency of the temperature sensor.

[0020] 3. By setting up a rotatable heat insulation plate and a movable heat insulation block, the movement channel of the temperature sensor is gradually opened and closed as the temperature sensor rotates from one test chamber to the next. This ensures the unimpeded rotation of the temperature sensor while further reducing the heat transfer from the test chamber to adjacent test chambers, effectively ensuring the temperature stability in different test chambers, reducing the energy consumption for restoring heat in the test chambers, and improving the detection efficiency of the temperature sensor.

[0030] The following examples are for illustrative purposes only and are not intended to limit the scope of the invention.

[0031] Referring to the figure, a production equipment for a high-precision temperature sensor includes a test bench 1, a control console 2 mounted on the side of the test bench 1, and further includes:

[0032] The installation mechanism includes a connecting platform 3, which is fixedly connected to the top of the test platform 1. A first electric rod 4 is installed at the bottom of the connecting platform 3. A fixed plate 6 and a limiting plate 9 are fixedly connected to the output end of the first electric rod 4. The limiting plate 9 is located below the fixed plate 6. A lifting groove 24 is provided on the top of the test platform 1. The limiting plate 9 and the lifting groove 24 are coaxially slidably engaged. Multiple mounting grooves 10 are provided on the limiting plate 9. Temperature sensors 11 are inserted into the mounting grooves 10.

[0033] The testing mechanism includes a lifting and rotating assembly connected to the bottom of the testing platform 1, with its output end extending into the lifting groove 24 and connected to a temperature measuring plate 14. The temperature measuring plate 14 is coaxially slidably connected within the lifting groove 24. A sliding groove 19 is coaxially formed on the temperature measuring plate 14, and multiple temperature measuring chambers 16 are connected to the sliding groove 19. The bottom ends of multiple temperature sensors 11 are coaxially and clearance-fitted with the multiple temperature measuring chambers 16, and are coaxially and rotatably fitted with the inside of the sliding groove 19. Heating blocks 15 are installed inside the temperature measuring chambers 16, and the multiple heating blocks 15 are used to apply different heating effects to the multiple temperature measuring chambers 16. The multiple temperature sensors 11 are detachably electrically connected to data connection devices 5. The top ends of the multiple data connection devices 5 penetrate through the fixed plate 6 and the connecting platform 3, and are electrically connected to the control console 2.

[0034] Multiple locking pieces 7 are fixedly connected to the side of the fixed plate 6, and multiple locking blocks 8 are fixedly connected to the top of the test platform 1. The multiple locking blocks 8 are locked and engaged with the locking pieces 7 one by one.

[0035] The lifting and rotating assembly includes a first motor 12, which is installed inside the bottom of the test bench 1. The output end of the first motor 12 extends through into the lifting groove 24 and is equipped with a second electric rod 13. The output end of the second electric rod 13 is fixedly connected to the temperature measuring plate 14.

[0036] Multiple temperature measuring chambers 16 are arranged in a circular array with the temperature measuring plate 14 as the center.

[0037] The temperature measuring plate 14 is made of fiber ceramic matrix composite material, which improves the heat insulation effect.

[0038] A second motor 23 is installed at the bottom of the temperature measuring chamber 16. The output end of the second motor 23 is coaxially fixedly connected to a base plate 22. The base plate 22 is coaxially slidably connected inside the temperature measuring chamber 16, and a heat insulation plate 17 and a heat conduction plate 18 are fixedly connected to the top. The heat insulation plate 17 and the heat conduction plate 18 are coaxially fitted with a clearance, and the heat insulation plate 17 is located outside the heat conduction plate 18. The heating block 15 is coaxially spaced between the heat insulation plate 17 and the heat conduction plate 18. Both sides of the heat insulation plate 17 and the heat conduction plate 18 have through slots for the temperature sensor 11 to rotate through.

[0039] The heating block 15 is fixedly connected to the temperature measuring plate 14 by a bracket that passes over the insulation plate 17. The heating block 15 is located inside the temperature measuring chamber 16 and is not on the track of the sliding groove 19.

[0040] The heat-conducting plate 18 has a hollow structure, which improves the heat transfer effect.

[0041] The sliding groove 19 located between two adjacent temperature measuring chambers 16 has a groove connected to its side. A third electric rod 21 is installed in the groove. A heat insulation block 20 is fixedly connected to the output end of the third electric rod 21. The heat insulation block 20 is slidably connected in the groove and moves into the sliding groove 19 when the output end of the third electric rod 21 extends, thus sealing and isolating the sliding groove 19.

[0042] The insulation block 20 has heat insulation material on both sides and heat absorption material in the middle to improve the heat insulation effect.

[0043] In this invention, when testing the performance of the temperature sensor 11, the first electric rod 4 is controlled by the control console 2 to retract its output end and lift the fixing plate 6 and the limiting plate 9 upward. When it is lifted to the top, the mounting slot 10 on the limiting plate 9 will be exposed from the lifting slot 24, making it convenient to insert the temperature sensor 11 into the mounting slot 10 in sequence for fixing. Then, the data connection device 5 is connected to the temperature sensor 11 so that it can feed back the temperature data to the control console 2 during detection.

[0044] The data connection device 5 is inserted in the connection platform 3. After the data connection device 5 is fixed, the first electric rod 4 works and its output end extends, driving the fixed plate 6 and the limit plate 9 to descend. When it descends to a certain height, the locking piece 7 and the locking block 8 fixedly connected on the fixed plate 6 engage, and then the first electric rod 4 stops working.

[0045] Then the second electric lever 13 operates, its output end extends, driving the temperature measuring plate 14 to rise. The temperature measuring plate 14 is made of fiber ceramic matrix composite material.

[0046] This composite material is made by combining fibers with a ceramic matrix. It combines the high strength of fibers with the high hardness and high temperature resistance of ceramics. Its thermal conductivity can be adjusted according to the type and content of fibers and matrix, generally between 5-20 W / (m·K), and has a good heat insulation effect.

[0047] The heat-conducting plate 18 adopts a hollow structure. The hollow structure of the heat-conducting plate 18 can make the heat more evenly distributed inside the plate. When the heating block 15 is working, the heat first accumulates around the heating point, and then is conducted through the material of the heat-conducting plate 18. Since the hollow part allows the heat to diffuse better in both the horizontal and vertical directions, it avoids local overheating, thereby making the temperature of the temperature measuring chamber 16 more uniform and ensuring the accuracy of the internal temperature of the temperature measuring chamber 16, thus making the temperature measurement more accurate.

[0048] The temperature of each temperature measuring chamber 16 is different. After the temperature sensor 11 has finished detecting in a temperature measuring chamber 16, the second motor 23 works and its output drives the base plate 22 to rotate, so that the through grooves on the insulation plate 17 and the heat guiding plate 18 on the base plate 22 rotate to the state of communicating with the sliding groove 19.

[0049] At this time, the first motor 12 works, and its output end drives the temperature measuring plate 14 to rotate slowly, so that the temperature sensor 11 can enter the sliding groove 19 through the through groove on the insulation plate 17 and the heat conduction plate 18. The temperature sensor 11 then rotates and enters the space between the insulation block 20 and the insulation plate 17.

[0050] At this time, the base plate 22 is rotated again under control, and the insulation plate 17 rotates accordingly to seal the outlets on both sides of the temperature measuring chamber 16, so as not to cause excessive heat loss.

[0051] Then the third electric rod 21 works, its output end retracts, causing the insulation block 20 to retract into the groove of the temperature measuring plate 14 and no longer close the sliding groove 19;

[0052] Then the temperature measuring plate 14 is rotated under control, which can drive the temperature sensor 11 to the next adjacent temperature measuring chamber 16. The third electric rod 21 works, and its output end extends, causing the insulation block 20 to close the sliding groove 19 again.

[0053] At this time, the temperature sensor 11 senses the temperature in the next adjacent temperature measuring chamber 16 and feeds back the temperature data to the control console 2 through the data connection device 5 to complete the test.

[0054] The insulation block 20 has a layered design, with insulation material at both ends and heat-absorbing material in the middle. It can absorb the heat emitted from the temperature measuring chamber 16 and thus will not affect the adjacent temperature measuring chamber 16.

[0055] This allows for better detection of the timeliness of the temperature sensor 11, because the temperature of each temperature measuring chamber 16 is different. After rapid rotation, the temperature of each temperature measuring chamber 16 is not affected, which can effectively detect the timeliness and accuracy of the temperature sensor 11, greatly improving the efficiency of detection performance.

[0056] After the test is completed, the second electric rod 13 is lowered, so that the temperature measuring plate 14 is lowered in the lifting groove 24;

[0057] The output end of the first electric lever 4 retracts, causing the temperature sensor 11 on the limit plate 9 to be exposed from the lifting slot 24, and then the next batch of temperature sensors 11 are replaced for testing.

[0058] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
