Description

Technical Field

[0001] The present invention relates to the technical field of testing devices, and in particular to a temperature sensor performance output testing device and a testing method thereof. Background Art

[0002] A temperature sensor is a sensor that senses temperature and converts it into a usable output signal. Temperature sensors are the core component of temperature measuring instruments and come in a wide variety of types. Temperature sensors require precise temperature control, data acquisition, and automated testing using test equipment to comprehensively evaluate sensor performance and ensure reliability in practical applications.

[0003] Chinese Patent Publication No. CN220120251U discloses a constant temperature test device for an infrared temperature sensor, including a constant temperature test device, wherein the constant temperature test device is provided with a plurality of clamping members, wherein the clamping members include two support rods, a fixed ring is fixed to the top of each of the support rods, a rotating ring is rotatably mounted on each of the two fixed rings, a plurality of movable clamping plates are provided between the two fixed rings and the corresponding rotating rings, the two rotating rings are fixedly connected by a connecting rod, the plurality of clamping plates between the fixed ring and the rotating ring are moved by a driving assembly, the fixed ring and the rotating ring are connected by a limit member, and the fixed ring and the plurality of corresponding clamping plates are connected by a sliding member;

[0004] In this existing design, although a clamping piece can be provided, the staff can use the clamping piece to quickly clamp the infrared temperature sensor.

[0008] The locking assembly includes a sliding rod and a slider, the sliding rod is installed on the surface of the first connecting rod, the slider is slidably connected to the surface of the sliding rod, a short block is fixedly installed on the side of the sliding rod, a short rod is fixedly installed on the surface of the short block, a spring is sleeved on the surface of the short rod, and a clamping block is fixedly installed on the bottom surface of the slider.

[0009] As a preferred embodiment of the temperature sensor performance output test device of the present invention, both ends of the slide bar are fixedly mounted with stoppers, and the stoppers and the slide bar are both rectangular in shape.

[0010] As a preferred embodiment of the temperature sensor performance output testing device of the present invention, an extension plate is fixedly mounted on the side of the slider, and the extension plate is slidably connected to the surface of the short rod.

[0011] As a preferred temperature sensor performance output testing device of the present invention, one end of the spring is fixedly connected to the side surface of the short block, and the other end of the spring is fixedly connected to the side surface of the extension plate.

[0012] As a preferred temperature sensor performance output testing device of the present invention, a second connecting rod is fixedly mounted on the surface of the first fixed plate, a counterweight is fixedly mounted on the surface of the second connecting rod, and the first connecting rod and the second connecting rod are symmetrically distributed.

[0013] As a preferred embodiment of the temperature sensor performance output test device of the present invention, the shapes and sizes of the card block and the card slots match each other, and the card slots are distributed in a circular array on the surface of the first fixed disk.

[0014] As a preferred embodiment of the temperature sensor performance output test device of the present invention, the card block is hollow, and a reinforcing rib is fixedly installed inside the card block.

[0015] As a preferred temperature sensor performance output testing device of the present invention, an auxiliary support rod is fixedly installed on the top surface of the base, the top end of the auxiliary support rod is arc-shaped, a groove is opened on the surface of the auxiliary support rod, and a ball is rollingly connected inside the groove.

[0016] As a preferred temperature sensor performance output testing device of the present invention, there are several groups of grooves, and the groups of grooves are evenly spaced and distributed on the surface of the auxiliary support rod, and the balls are in contact with the surface of the turntable.

[0017] According to another aspect of the present invention, a temperature sensor performance output test device and a test method thereof are provided, comprising the following steps:

[0018] S1. Before testing, the staff first inserts the temperature sensor between the first fixed disk and the second fixed disk, and uses the locking assembly to release the limit of the rotating disk. Specifically, by pulling the extension plate, the extension plate slides on the surface of the short rod, and the extension rod squeezes the spring. Since the surface of the extension rod is connected to the side of the slider, the extension rod drives the slider to slide on the surface of the slide rod until the block is disengaged from the inside of the slot;

[0019] S2. At this time, the temperature sensor is clamped and fixed by the clamping assembly, the turntable releases the locking restriction, and the first connecting rod is rotated in the direction forward of the slot. The first connecting rod drives the turntable to rotate, and the turntable drives the second connecting rod and the counterweight block on its surface to rotate. When the turntable rotates, friction occurs between its surface and the ball, which drives the ball to roll inside the groove, thereby reducing the friction between the turntable and the auxiliary support rod;

[0020] S3. At the same time, the turntable drives the limiting groove on its surface to rotate. The limiting groove squeezes the connecting block during rotation. The connecting block is squeezed and drives the clamping block to move. At this time, under the coordinated movement of the connecting block and the limiting groove, the clamping block slides in the cavity until the clamping block clamps the infrared temperature sensor.

[0021] S4. After the clamping block is fixed to the temperature sensor, the turntable is locked again by the locking assembly. Specifically, after the clamping block is fixed in position, the extension plate is released and pulled. Since the side surface of the extension plate is connected to one end of the spring, the extension plate slides in the opposite direction on the surface of the short rod under the action of the spring until the slider drives the blocking block to be reinserted into the slot. At this time, since the second connecting rod and the first connecting rod are symmetrically arranged, the counterweight block on the surface of the second connecting rod exerts a force on it in the opposite direction of the movement direction of the first connecting rod, that is, the counterweight block drives the turntable to move in the opposite direction of the slot, so the counterweight block can make the blocking block further engage with the slot;

[0022] S5. Subsequently, the temperature sensor can be tested using the test device body.

[0023] Compared with the prior art, the advantages and positive effects of the present invention are:

[0024] In the present invention, a clamping assembly and a locking assembly are provided, and the turntable is driven to rotate by the first connecting rod, so that the clamping block clamps the sensor, which is convenient for the staff to quickly fix the clamping block. At the same time, it is convenient to control the clamping force of the clamping block by adjusting the position of the clamping block and the clamping slot, so as to avoid damage to the sensor or inaccurate testing caused by excessive or insufficient clamping force. Auxiliary support rods, grooves and balls are also provided. The auxiliary support rod can improve the supporting stability of the second fixed disk, and the ball and the turntable on the side of the second fixed disk are made to fit together, which can reduce the friction between the turntable and the auxiliary support rod, and avoid jamming when the turntable is rotated.

[0039] In the following description, many specific details are set forth to facilitate a full understanding of the present invention. However, the present invention may also be implemented in other ways than those described herein. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0040] Example 1

[0041] In the prior art, the existing constant temperature test device for temperature sensors includes a test device main body 1, and this test device also has a plurality of clamping members provided on the constant temperature test device, the clamping members include two support rods, the top ends of the two support rods are fixed with a fixing ring, and the two fixing rings are rotatably equipped with a rotating ring, and a plurality of movable clamping plates are provided between the two fixing rings and the corresponding rotating rings, the two rotating rings are fixedly connected by a connecting rod, and the plurality of clamping plates between the fixing ring and the rotating ring are moved by a driving assembly, the fixing ring and the rotating ring are connected by a limit member, and the fixing ring and the plurality of corresponding clamping plates are connected by a sliding member. By setting the clamping members, the staff uses the clamping members to quickly clamp the infrared temperature sensor. Specifically, the staff inserts the infrared temperature sensor into the two fixing rings so that the infrared temperature sensor is placed between the plurality of clamping plates, and then quickly clamps the infrared temperature sensor by rotating the connecting rod. The clamping process is convenient and fast, and the rapid clamping of the infrared temperature sensor is realized, thereby improving the practicality of the constant temperature test device.

[0042] This application combines the above-mentioned prior art, such as Figures 1-9 As shown, the present invention provides a technical solution: a temperature sensor performance output test device, a test device body 1 is provided with a plurality of clamping assemblies 2, the clamping assembly 2 includes a base 201, a first support rod 202 and a second support rod 203, the first support rod 202 and the second support rod 203 are both mounted on the top surface of the base 201, the base 201 is mounted on the top surface of the test device body 1, the top of the first support rod 202 is fixedly mounted with a first fixed plate 204, the top of the second support rod 203 is fixedly mounted with a second fixed plate 205, the first fixed plate 204 and the second fixed plate 205 are fixedly mounted. The sides of the fixed plate 205 are rotatably connected to a rotating disk 206, a cavity 207 is provided inside the rotating disk 206, a limiting groove 208 is provided on the surface of the rotating disk 206, a clamping block 209 is slidably connected to the inside of the cavity 207, a connecting block 210 is installed on the surface of the clamping block 209, and the connecting block 210 is slidably connected to the inside of the limiting groove 208, a card slot 211 is provided on the surface of the first fixed plate 204, and the rotating disks 206 on the sides of the first fixed plate 204 and the second fixed plate 205 are connected by a first connecting rod 212, and a locking component 3 is provided on the surface of the first connecting rod 212;

[0043] The locking assembly 3 includes a slide rod 301 and a slider 302. The slide rod 301 is installed on the surface of the first connecting rod 212. The slider 302 is slidably connected to the surface of the slide rod 301. A short block 303 is fixedly installed on the side of the slide rod 301. A short rod 304 is fixedly installed on the surface of the short block 303. A spring 305 is sleeved on the surface of the short rod 304. A clamping block 306 is fixedly installed on the bottom surface of the slider 302.

[0044] In this embodiment: a clamping component 2 is provided, which drives the turntable 206 to rotate by rotating the first connecting rod 212, and the turntable 206 drives the clamping block 209 to slide in the cavity 207. At the same time, the sliding trajectory of the clamping block 209 is limited by the connecting block 210 and the limit slot 208. The clamping block 209 that slides according to a specific motion trajectory can clamp the sensor, which is convenient for the staff to quickly fix the clamping block 209. At the same time, it is convenient to control the clamping force of the clamping block 209 by adjusting the position of the clamping block 306 and the clamping slot 211 to avoid damage to the sensor or inaccurate testing caused by excessive or insufficient clamping force. A locking component 3 is also provided, which is connected to the clamping block 306 and the clamping slot 211 to fix the rotation angle of the turntable 206. No manual fixation is required, which reduces the probability of test errors.

[0045] Combining the above solutions:

[0046] Going further:

[0047] like Figures 4 to 6 As shown;

[0048] To prevent slider 302 from rotating, in an optional embodiment, stops 307 are fixedly mounted at both ends of slide bar 301. Both stops 307 and slide bar 301 are rectangular in shape. Stops 307 can be bolted or welded to slide bar 301 to ensure stable installation and smooth operation. Stops 307 can be made of stainless steel or aluminum alloy, which are both strong and corrosion-resistant.

[0049] In this embodiment, the block 307 and the slide bar 301 are both set to be rectangular to prevent the slider 302 from rotating itself when the slider 302 moves on the surface of the slide bar 301, thereby avoiding torsional damage to the spring 305 and improving the service life of the device to a certain extent.

[0050] Combining the above solutions:

[0051] Going further:

[0052] like Figures 4 to 6 As shown;

[0053] To facilitate removal of the block 306, in an optional embodiment, an extension plate 308 is fixedly mounted on the side of the slider 302. The extension plate 308 is slidably connected to the surface of the short rod 304. The extension plate 308 can be bolted or welded to the slider 302 to ensure stable installation and smooth operation. The extension plate 308 can be made of stainless steel or aluminum alloy, which has high strength and corrosion resistance.

[0054] In this embodiment: by pulling the extension plate 308, the slider 302 can slide on the surface of the slide rod 301. The extension plate 308 increases the contact area between the staff's hand and the slider 302, making it easier to slide the slider 302 to remove the block 306 from the slot 211, thereby improving the locking efficiency.

[0055] Combining the above solutions:

[0056] Going further:

[0057] like Figures 4 to 6 As shown;

[0058] To facilitate the insertion of the locking block 306 into the locking slot 211, in an optional embodiment, one end of the spring 305 is fixedly connected to the side of the short block 303, and the other end of the spring 305 is fixedly connected to the side of the extension plate 308. The spring 305 can be connected to the short block 303 and the extension plate 308 by bolts or welding to ensure the installation stability and smooth operation of the spring 305. The spring 305 can be made of spring steel, which has good elasticity and durability.

[0059] In this embodiment, when the extension plate 308 is released, the spring 305 loses the external force and, under the action of its own elastic force, drives the extension plate 308 to slide in the opposite direction. The extension plate 308 then drives the slider 302 to move in the opposite direction until the block 306 is pushed into the slot 211. After the extension plate 308 is released, the block 306 automatically resets.

[0060] Combining the above solutions:

[0061] Going further:

[0062] like Figure 7 As shown;

[0063] To further secure the block 306 within the slot 211, in an optional embodiment, a second connecting rod 213 is fixedly mounted on the surface of the first fixed plate 204. A counterweight 214 is fixedly mounted on the surface of the second connecting rod 213. The first connecting rod 212 and the second connecting rod 213 are symmetrically arranged. The second connecting rod 213 can be bolted or welded to the first fixed plate 204 to ensure installation stability and smooth operation of the second connecting rod 213. The second connecting rod 213 can be made of stainless steel or aluminum alloy, which has high strength and corrosion resistance.

[0064] In this embodiment: since the second connecting rod 213 and the first connecting rod 212 are symmetrically arranged, the counterweight block 214 on the surface of the second connecting rod 213 applies a force to it in the opposite direction of the movement direction of the first connecting rod 212, that is, the counterweight block 214 drives the turntable 206 to move in the opposite direction of the slot 211, so the counterweight block 214 can make the block 306 further engage with the slot 211.

[0065] Combining the above solutions:

[0066] Going further:

[0067] like Figures 1 to 7 As shown;

[0068] To lock the turntable 206, in an optional embodiment, the blocks 306 and the slots 211 match in shape and size, and the slots 211 are distributed in a circular array on the surface of the first fixed disk 204. The blocks 306 and the slots 211 match in shape and size, and their distribution in a circular array on the surface of the first fixed disk 204 facilitates adjustment of the positions of the blocks 306 and the slots 211, thereby facilitating the securing of the turntable 206 when it is rotated to different angles.

[0069] Combining the above solutions:

[0070] Going further:

[0071] like Figures 4 and 5 As shown;

[0072] To enhance the strength of the clamping block 306, in an optional embodiment, the clamping block 306 is hollowed out, and a reinforcing rib 309 is fixedly mounted inside the clamping block 306. The reinforcing rib 309 can be bolted or welded to the clamping block 306 to ensure installation stability and smooth operation. The reinforcing rib 309 can be made of stainless steel or aluminum alloy, which offers high strength and corrosion resistance.

[0073] In this embodiment, reinforcing ribs 309 are provided inside the block 306 to increase the support strength of the block 306 and prevent the block 306 from bending or breaking when the block 306 and the slot 211 are locked, thereby preventing the locking failure.

[0074] Combining the above solutions:

[0075] Going further:

[0076] like Figures 7 to 9 As shown;

[0077] To further support the second fixed plate 205, in an optional embodiment, an auxiliary support rod 215 is fixedly mounted on the top surface of the base 201. The top of the auxiliary support rod 215 is arc-shaped, and the surface of the auxiliary support rod 215 is provided with a groove 216. A ball bearing 217 is rollingly connected within the groove 216. The auxiliary support rod 215 can be connected to the base 201 by bolts or welding, ensuring the installation stability and smooth operation of the auxiliary support rod 215. The auxiliary support rod 215 can be made of stainless steel or aluminum alloy, which has high strength and corrosion resistance.

[0078] In this embodiment: by installing an auxiliary support rod 215 on the top surface of the base 201 and making the top end of the auxiliary support rod 215 contact the turntable 206, the stability of the second fixed plate 205 can be further improved, and the shaking of the second fixed plate 205 can be avoided to affect the clamping effect of the sensor.

[0079] Combining the above solutions:

[0080] Going further:

[0081] like Figures 7 to 9 As shown;

[0082] To reduce friction between turntable 206 and auxiliary support rod 215, in an optional embodiment, grooves 216 are arranged in multiple groups, evenly spaced on the surface of auxiliary support rod 215, with balls 217 in contact with the surface of turntable 206. Balls 217 can be bolted or welded to grooves 216 to ensure stable installation and smooth operation. Balls 217 can be made of stainless steel or aluminum alloy, which are both strong and corrosion-resistant.

[0083] In this embodiment: a groove 216 is opened on the surface of the auxiliary support rod 215, and a ball 217 is arranged inside the groove 216. The ball 217 contacts the surface of the turntable 206, which can reduce the friction between the turntable 206 and the auxiliary support rod 215, thereby avoiding jamming when the turntable 206 rotates and affecting the clamping effect of the sensor.

[0084] Example 2

[0085] The temperature sensor performance output test device of the present application is described in detail in Example 1. This embodiment provides a test method of the above device, which specifically includes the following steps:

[0086] S1. Before testing, the staff first inserts the temperature sensor between the first fixed disk 204 and the second fixed disk 205, and uses the locking assembly 3 to release the limit of the rotating disk 206. Specifically, by pulling the extension plate 308, the extension plate 308 slides on the surface of the short rod 304, and the extension plate 308 squeezes the spring 305. Since the surface of the extension plate 308 is connected to the side of the slider 302, the extension plate 308 drives the slider 302 to slide on the surface of the slide rod 301 until the block 306 is disengaged from the inside of the slot 211;

[0087] S2. At this time, the temperature sensor is clamped and fixed by the clamping assembly 2 again, the lock restriction of the turntable 206 is released, and the first connecting rod 212 is rotated in the direction of the card slot 211. The first connecting rod 212 drives the turntable 206 to rotate. At the same time, the turntable 206 drives the second connecting rod 213 and the counterweight block 214 on its surface to rotate. When the turntable 206 rotates, friction occurs between its surface and the ball 217, which in turn drives the ball 217 to roll inside the groove 216, thereby reducing the friction between the turntable 206 and the auxiliary support rod 215.

[0088] S3. At the same time, the turntable 206 drives the limiting groove 208 on its surface to rotate. The limiting groove 208 squeezes the connecting block 210 during rotation. After being squeezed, the connecting block 210 drives the clamping block 209 to move. At this time, under the coordinated movement of the connecting block 210 and the limiting groove 208, the clamping block 209 slides in the cavity 207 until the clamping block 209 clamps the infrared temperature sensor.

[0089] S4. After the clamping block 209 fixes the temperature sensor, the rotating disk 206 is locked again by the locking assembly 3. Specifically, after the clamping block 209 is fixed in position, the extension plate 308 is released. Since the side surface of the extension plate 308 is connected to one end of the spring 305, the extension plate 308 slides in the opposite direction on the surface of the short rod 304 under the action of the spring 305 until the slider 302 drives the blocking block 306 to be reinserted into the slot 211. At this time, since the second connecting rod 213 and the first connecting rod 212 are symmetrically arranged, the counterweight 214 on the surface of the second connecting rod 213 applies a force opposite to the movement direction of the first connecting rod 212, that is, the counterweight 214 drives the rotating disk 206 to move in the opposite direction of the slot 211, so the counterweight 214 can make the blocking block 306 further engage with the slot 211.

[0090] S5. Subsequently, the test device body 1 can be used to test the temperature sensor.

[0091] The above description is merely a preferred embodiment of the present invention and does not constitute any other form of limitation to the present invention. Any person skilled in the art may utilize the technical contents disclosed above to change or modify them into equivalent embodiments with equivalent changes for application in other fields. However, any simple modification, equivalent change, and modification of the above embodiments made in accordance with the technical essence of the present invention without departing from the technical solution of the present invention shall still fall within the scope of protection of the technical solution of the present invention.

10. A testing method using the temperature sensor performance output testing device according to any one of claims 1 to 9, characterized in that: The steps include: S1. Before the test, the staff first inserts the temperature sensor between the first fixed disk (204) and the second fixed disk (205), and uses the locking component (3) to release the limit of the rotating disk (206). Specifically, by pulling the extension plate (308), the extension plate (308) slides on the surface of the short rod (304), and at the same time, the extension rod (308) squeezes the spring (305). Since the surface of the extension rod (308) is connected to the side of the slider (302), the extension rod (308) drives the slider (302) to slide on the surface of the slide rod (301) until the block (306) is disengaged from the inside of the slot (211); S2. At this time, the temperature sensor is clamped and fixed by the clamping assembly (2), the turntable (206) is unlocked, and the first connecting rod (212) is rotated in the direction of the slot (211). The first connecting rod (212) drives the turntable (206) to rotate, and at the same time, the turntable (206) drives the second connecting rod (213) and the counterweight (214) on its surface to rotate. When the turntable (206) rotates, friction occurs between its surface and the ball (217), thereby driving the ball (217) to roll inside the groove (216), thereby reducing the friction between the turntable (206) and the auxiliary support rod (215); S3. At the same time, the turntable (206) drives the limiting groove (208) on its surface to rotate, and the limiting groove (208) squeezes the connecting block (210) during the rotation. After the connecting block (210) is squeezed, it drives the clamping block (209) to move. At this time, under the coordinated movement of the connecting block (210) and the limiting groove (208), the clamping block (209) slides in the cavity (207) until the clamping block (209) clamps the infrared temperature sensor; S4. After the clamping block (209) is fixed to the temperature sensor, the turntable (206) is locked again by the locking assembly (3). Specifically, after the clamping block (209) is fixed in position, the extension plate (208) is released and pulled. Since the side surface of the extension plate (208) is connected to one end of the spring (305), the extension plate (208) slides in the opposite direction on the surface of the short rod (304) under the action of the spring (305) until the slider (302) drives the clamping block (306) to re-engage. When the second connecting rod (213) is newly inserted into the slot (211), since the second connecting rod (213) and the first connecting rod (212) are symmetrically arranged, the counterweight (214) on the surface of the second connecting rod (213) exerts a force on the second connecting rod (213) in the opposite direction of the movement of the first connecting rod (212), that is, the counterweight (214) drives the turntable (206) to move in the opposite direction of the slot (211), so the counterweight (214) can further engage the block (306) with the slot (211); S5. Subsequently, the temperature sensor can be tested using the test device body (1).
