Description

Technical Field

[0001] This invention relates to thermal shock testing of sensors, and more particularly to a testing device for temperature sensors. Background Technology

[0002] A temperature sensor is an instrument used to detect temperature. After the temperature sensor is manufactured, it needs to undergo a thermal shock test to test its resistance to thermal shock.

[0003] Patent publication number CN211527677U discloses a thermal shock testing device for a temperature sensor, including a high-temperature furnace. One side of the furnace is equipped with a clamp for mounting a temperature sensor and a drive mechanism for reciprocating the clamp. The clamp causes the temperature sensor to extend into and exit the furnace. In use, the temperature sensor is first inserted into the furnace for high-temperature heating, then removed and cooled by cold air from a fan. This amplifies the temperature change amplitude of the sensor, enabling thermal shock testing. However, during the thermal shock test, the fan cannot rapidly cool the high-temperature sensor to -55 degrees Celsius because the air temperature is above zero degrees Celsius. Therefore, the temperature of the sensor does not drop quickly enough during the thermal shock test, resulting in low test accuracy.

[0004] To address the aforementioned shortcomings, we have designed a testing device for temperature sensors that can rapidly cool and heat up the sensors, thereby improving testing accuracy. Summary of the Invention

[0040] Example 1

[0041] A testing device for a temperature sensor, such as Figure 1 and Figure 2As shown, the device includes a thermal shock unit 1, a hatch 2, a placement rack 21, a guide rail 22, a partition plate 23, a replacement mechanism 3, and a storage mechanism 4. The partition plate 23 is fixed to the middle of the interior of the thermal shock unit 1, dividing the interior of the thermal shock unit 1 into two spaces. There are two hatches 2, which are rotatably connected to the left and right sides of the front of the thermal shock unit 1. The bottom wall of the thermal shock unit 1 is connected to two sets of guide rails 22, with two guide rails in each set, arranged on the left and right sides of each set. There are two placement racks 21, which are slidably connected between the guide rails 22 in the same set. The partition plate 23 is equipped with a replacement mechanism 3, which can replace the cold and hot air in the left and right sides of the thermal shock unit 1. The top wall of the thermal shock unit 1 is equipped with a storage mechanism 4, which can store the hot and cold air used.

[0042] like Figure 2 , Figure 3 , Figure 4 and Figure 5 As shown, the replacement mechanism 3 includes a sealing frame 31, a first vacuum pump 32, a gear 33, a sealing element 34, a single-section electric push rod 35, and a rack 36. There are two first vacuum pumps 32, which are respectively installed on the upper and lower sides of the partition plate 23. The surface of the first vacuum pump 32 is coated with a high-temperature resistant coating. There are four sealing frames 31, which are respectively connected to the left and right sides of the upper and lower parts of the partition plate 23. Four sealing elements are rotatably connected to each sealing frame 31 from top to bottom. The closing element 34 has a gear 33 fixedly connected to its rear. There are four single-section electric push rods 35, two of which are installed on the upper rear side of the lower closing frame 31, and the other two are installed on the lower rear side of the upper closing frame 31. The surface of the single-section electric push rod 35 is coated with a high-temperature resistant coating. There are four racks 36, which are connected to the telescopic rods of the single-section electric push rod 35. Each rack 36 meshes with the adjacent gear 33.

[0043] like Figure 2 and Figure 6 As shown, the storage mechanism 4 includes a storage unit 41, an air duct 42, and a motor 43. There are two storage units 41, which are respectively connected to the left and right sides of the inner top wall of the thermal shock device 1. The storage units 41 are coated with high-temperature resistant paint. There are two motors 43, which are respectively installed on the upper left and right sides of the inner rear wall of the thermal shock device 1. The surfaces of the motors 43 are coated with high-temperature resistant paint. There are two air ducts 42, which are respectively connected to the output shaft of the motors 43 through couplings. The air ducts 42 are located directly below the storage units 41.

[0044] When thermal shock testing of temperature sensors is required, the testing device for this temperature sensor can be used. First, rotate and open the hatch 2, then pull the placement rack 21 forward. Next, place the two temperature sensors to be tested on the placement rack 21 respectively. Then, push the placement rack 21 backward into the thermal shock chamber 1, and reverse and close the hatch 2. Then, control the single-section electric push rod 35 to retract, causing the lower single-section electric push rod 35 to drive the lower rack 36 to move upward, and the upper single-section electric push rod 35 to drive the upper rack 36 to move downward. The driven gear 33 drives the sealing member 34 to rotate, so that the sealing member 34 closes the sealing rack 31. At this time, the left and right sides of the thermal shock chamber 1 are closed. The parts are not interconnected. Then, the thermal shock device 1 is activated, and hot air is supplied from the lower left to the inner left, and cold air is supplied from the lower right to the inner right. This heats the temperature sensor on the left to 70 degrees Celsius and cools the temperature sensor on the right to -55 degrees Celsius. At this time, the internal temperature of the thermal shock device 1 can be observed in the upper right part. When the temperature sensor is heated or cooled to the corresponding degree, the supply of hot or cold air is stopped. Then, the temperature sensor on the left is cooled and the temperature sensor on the right is heated. This can subject the temperature sensor to thermal shock. First, the single-section electric push rod 35 is controlled to extend, causing the lower single-section electric push rod 35 to drive the lower rack 36 to move downwards, and the upper single-section electric push rod... The telescopic rod 35 drives the upper rack 36 to move upward, and the drive gear 33 drives the sealing member 34 to rotate in the opposite direction, causing the sealing frame 31 to open. At this time, the left and right inner parts of the thermal shocker 1 are connected. At the same time, the first exhaust fan 32 is turned on, so that the upper first exhaust fan 32 delivers cold air from the right inner part of the thermal shocker 1 to the left inner part, and the lower first exhaust fan 32 delivers hot air from the left inner part of the thermal shocker 1 to the right inner part. In this way, the hot and cold air output from the thermal shocker 1 can be replaced and reused. After the gas replacement in the left and right inner parts of the thermal shocker 1 is completed, the first exhaust fan 32 is turned off and the sealing member 34 is closed. Then, the thermal shocker 1 is controlled to deliver cold air to the left inner part and hot air to the right inner part. This allows for thermal shock testing of the temperature sensor. Since the previous cold and hot air have cooled and heated the left and right sides of the thermal shock chamber 1 respectively, the gas supplied by the thermal shock chamber 1 can rapidly change the temperature of the temperature sensor, thereby improving test accuracy. The above operation is then repeated to perform two more thermal shock tests on the temperature sensor to complete the test. After the thermal shock test of the temperature sensor is completed, the thermal shock chamber 1 is turned off, and the storage tank 41 and motor 43 are turned on. At this time, the output shaft of motor 43 drives the fan 42 to rotate, causing the fan 42 to transport the gas inside the thermal shock chamber 1 upwards into the storage tank 41. When the storage tank 41 is full of gas, the storage tank 41 and motor 43 are turned off.In this way, hot air and cold air can be stored for future use. When the next batch of temperature sensors are tested, the stored gas can be used to heat and cool the left and right inner parts of the thermal shocker 1. In this way, the temperature of the temperature sensors can be quickly decreased or increased, and the temperature change range of the temperature sensors can be enlarged, further improving the test accuracy. When the temperature inside the thermal shocker 1 returns to room temperature, the hatch 2 is rotated and opened, and then the tested temperature sensors are taken out, and the performance of the temperature sensors is detected. If the performance of the temperature sensors is in good condition after thermal shock, it means that the temperature sensors are qualified. If the performance of the temperature sensors is abnormal after thermal shock, it means that the temperature sensors are unqualified. In summary, the thermal shock test of the temperature sensors can be carried out, and the temperature change range of the temperature sensors is large, so that the test data of the temperature sensors can be prevented from being in error.

[0045] Embodiment 2

[0046] On the basis of Embodiment 1, as Figure 2 、 Figure 7 、 Figure 8 and Figure 9 shown, it further includes a blowing mechanism 5. The blowing mechanism 5 includes a拨动件51, a squeezing member 52, a blowing member 53 and a squeezing spring 54. The number of the拨动件51 is two, and the two拨动件51 are respectively fixedly connected to the middle of the top of the air guiding member 42. The number of the blowing members 53 is two, and the two blowing members 53 are respectively rotatably connected to the left and right sides of the lower part of the inner wall of the thermal shocker 1. The number of the squeezing members 52 is two, and the two squeezing members 52 are respectively slidably connected to the left and right sides of the upper part of the inner wall of the thermal shocker 1. The lower part of the squeezing member 52 is in squeezing fit with the upper part of the blowing member 53, and the拨动件51 is in squeezing fit with the upper part of the squeezing member 52. The number of the squeezing springs 54 is four, and the four squeezing springs 54 are respectively connected between the front and rear parts on the upper side of the squeezing member 52 and the thermal shocker 1. The squeezing springs 54 are all wound around the thermal shocker 1.

[0047] When the thermal shock device 1 heats and cools the inner left and inner right parts, the blower mechanism 5 can be used for operation. First, the induced draft fan 42 is rotated. At this time, the induced draft fan 42 will draw the gas delivered to the lower part of the thermal shock device 1 upward, and the induced draft fan 42 will also drive the actuating member 51 to rotate. When the actuating member 51 rotates to contact the extrusion member 52, the actuating member 51 will squeeze the extrusion member 52 to the side away from each other, and the extrusion spring 54 will be compressed. At this time, the extrusion member 52 will squeeze the blower 53 to rotate, so that the blower 53 will push the lower part of the thermal shock device 1 upward. The delivered gas is pushed upwards, which accelerates the speed at which the gas fills the interior of the thermal shock device 1. When the actuating element 51 moves away from the squeezing element 52, the squeezing element 52 moves to the side closer to each other under the action of the squeezing spring 54, and releases the blower element 53. The blower element 53 rotates in the opposite direction under its own gravity. When the gas fills the interior of the thermal shock device 1, the driving of the induced draft element 42 stops. In summary, this can accelerate the speed at which the gas fills the interior of the thermal shock device 1, improve the testing speed, and also assist people in heating and cooling the temperature sensor.

[0048] like Figure 2 , Figure 10 and Figure 11 As shown, it also includes a guiding mechanism 6, which includes a multi-section electric push rod 61, a second vacuum pump 62, a collecting component 63, and a fixing block 64. There are two multi-section electric push rods 61, which are respectively installed on the rear left side of the inner bottom wall and the rear right side of the inner top wall of the thermal shock absorber 1. The surfaces of the multi-section electric push rods 61 are coated with a high-temperature resistant coating. The multi-section electric push rods 61 are electrically connected to the thermal shock absorber 1. There are two fixing blocks 64, which are respectively connected to the multi-section electric push rods 61. On the telescopic rod 1, there are two second vacuum pumps 62. The two second vacuum pumps 62 are respectively connected to the left rear side of the inner bottom wall of the thermal shock device 1 and the right rear side of the inner top wall of the thermal shock device 1. The surface of the second vacuum pumps 62 is coated with high temperature resistant coating. There are two collection parts 63. The two collection parts 63 are respectively fixed to the second vacuum pumps 62. The collection parts 63 are made of soft material. The fixing block 64 on the left is connected to the upper part of the collection part 63, and the fixing block 64 on the right is connected to the lower part of the collection part 63. The second vacuum pumps 62 are connected to the collection parts 63.

[0049] When replacing the cold and hot air in the left and right sides of the thermal shock absorber 1, the guiding mechanism 6 can be used. First, the second exhaust fan 62 is turned on. At this time, the second exhaust fan 62 on the left side will draw in the gas from the upper left side of the thermal shock absorber 1 through the left collection member 63, and transport the drawn-in gas to the first exhaust fan 32 on the lower side. In this way, it can assist the first exhaust fan 32 on the lower side in transporting the gas in the left side of the thermal shock absorber 1 to the right side. At the same time, the second exhaust fan 62 on the right side will also transport the gas from the lower right side of the thermal shock absorber 1 to the first exhaust fan 32 on the upper side through the right collection member 63. In this way, it can assist the first exhaust fan 32 on the upper side in transporting the gas in the right side of the thermal shock absorber 1 to the left side. In addition, multiple exhaust fans can be turned on during the auxiliary process. The second pump 62 is shut off, and the multi-section electric push rod 61 is extended, causing the multi-section electric push rod 61 on the left to move the upper part of the left collection member 63 downward, and the multi-section electric push rod 61 on the right to move the lower part of the right collection member 63 upward. As a result, the collection member 63 undergoes adaptive deformation, thus drawing the gas layer by layer to the vicinity of the first pump 32, thereby improving the auxiliary effect. After the replacement of cold and hot air in the left and right inner parts of the cold and hot shocker 1 is completed, the second pump 62 is shut off, and the multi-section electric push rod 61 is extended, which then moves the upper part of the left collection member 63 upward and the lower part of the right collection member 63 downward. In summary, this can assist the first pump 32 in replacing cold and hot air.

[0050] like Figure 2 , Figure 12 , Figure 13 , Figure 14 and Figure 15 As shown, it also includes a striking mechanism 7, which includes a sliding frame 71, a compression spring 72, a triangular block 73, and a striking block 74. There are two sliding frames 71, which are slidably connected to the upper closed frame 31. The lower part of the sliding frame 71 is located inside the upper part of the lower closed frame 31. There are four compression springs 72, which are respectively connected to the front and rear sides of the upper part of the sliding frame 71 and between the upper closed frame 31. The compression springs 72 are all wound around the upper part of the sliding frame 71. There are two striking blocks 74, which are fixed to the upper middle part of the sliding frame 71. A triangular block 73 is connected to the upper middle part of the sliding frame 71. The triangular block 73 is pressed and engaged with the actuating member 51.

[0051] When the internal temperature of the thermal shock unit 1 drops to below zero degrees Celsius, frost may form on the components of the enclosure 31. To prevent the enclosure 34 from freezing, the striking mechanism 7 can be used. When the actuating member 51 rotates to contact the triangular block 73, the actuating member 51 will press the triangular block 73 downward, causing the triangular block 73 to move the sliding frame 71 and the striking block 74 downward. As a result, the compression spring 72 is compressed. When the actuating member 51 rotates away from the triangular block 73, under the action of the compression spring 72, the sliding frame 71 will move the striking block 74 upward. At this time, the striking block 74 will strike the upper enclosure 31, and the lower part of the sliding frame 71 will strike the lower enclosure 31. This will cause the enclosure 31 and the components on it to vibrate, thereby shaking off the frost on the enclosure 31 and the components on it, thus preventing the enclosure 31 and the components on it from freezing.

[0052] like Figure 2 , Figure 17 and Figure 19 As shown, it also includes a push-out mechanism 8, which includes push-out springs 85 and a compression assembly. There are four push-out springs 85, which are respectively connected to the lower left and right sides of the placement frame 21 and the guide rail 22. All push-out springs 85 are wound around the guide rail 22. The lower part of the cold and hot shocker 1 is provided with a compression assembly.

[0053] like Figure 16 , Figure 17 and Figure 18 As shown, the extrusion assembly includes an extrusion frame 81, an ejector 82, a return spring 83, and a pressing member 84. There are two ejector 82s, which are slidably connected to the lower left and right sides of the thermal shocker 1. The upper rear side of the ejector 82 is inclined downwards and backwards, and the front side of the ejector 82 is in a pressing engagement with the hatch 2. There are two return springs 83, which are connected between the rear of the ejector 82 and the thermal shocker 1. The return springs 83 are wound around the thermal shocker 1. The extrusion frame 81 is fixed to the right-side fixing block 64 and is in a pressing engagement with the upper rear side of the right-side ejector 82. The pressing member 84 is fixed to the left side of the left-side fixing block 64 and is in a pressing engagement with the upper rear side of the left-side ejector 82.

[0054] After the test, the temperature sensor can be removed using the ejection mechanism 8. Initially, the ejection spring 85 is compressed. When the thermal shock device 1 returns to normal temperature after the test, it controls the extension of the right-side multi-section electric push rod 61. This extension causes the right-side multi-section electric push rod 61 to move downwards via the right-side fixed block 64, causing the compression frame 81 to move downwards. At this time, the compression frame 81 pushes the right-side ejector 82 forward, causing the ejector 82 to push the right-side hatch 2 forward. Simultaneously, the right-side return spring 83 is compressed. At the same time, the thermal shock device 1 also controls the left-side multi-section electric push rod 61 to retract. This retraction causes the left-side multi-section electric push rod 61 to move downwards via the left-side fixed block 64, causing the compression member 84 to push the left-side ejector 82 forward, pushing the left-side hatch 2 forward. Subsequently, the reset spring 83 on the left side is compressed, thus automatically opening the hatch 2. When the hatch 2 rotates open and no longer presses against the front of the placement rack 21, the placement rack 21 moves forward out of the thermal shock device 1 under the action of the push-out spring 85, allowing the temperature sensor to be removed. After the temperature sensor is removed, the fixing block 64 on the left side moves the pressing member 84 upward, causing the pressing member 84 to move away from the upper rear side of the push-out member 82 on the left side. The fixing block 64 on the right side moves the squeezing frame 81 upward, causing the squeezing frame 81 to move away from the upper rear side of the push-out member 82 on the right side. At this time, under the action of the reset spring 83, the push-out member 82 moves backward and no longer presses against the hatch 2. Then the placement rack 21 moves backward, the push-out spring 85 is compressed, and then the hatch 2 is reversed and closed. In summary, this helps people remove the temperature sensor after testing.
