Description

Technical Field

[0001] This invention relates to the field of testing equipment technology, and in particular to a temperature sensor performance output testing device and its testing method. Background Technology

[0002] A temperature sensor is a sensor that can sense temperature and convert it into a usable output signal. Temperature sensors are a core component of temperature measuring instruments, and there are many different types. Temperature sensors need to undergo precise temperature control, data acquisition, and automated testing using testing equipment to comprehensively evaluate their performance and ensure their reliability in practical applications.

[0003] Chinese Patent Publication No. CN220120251U discloses a constant temperature testing device for an infrared temperature sensor, comprising a constant temperature testing device, wherein the constant temperature testing device is provided with several clamping components, each clamping component including two support rods, each support rod having a fixed ring fixed at its top end, each fixed ring having a rotating ring rotatably mounted on it, each fixed ring having several movable clamping plates between it and its corresponding rotating ring, the two rotating rings being fixedly connected by a connecting rod, the clamping plates between the fixed rings and the rotating rings being moved by a driving component, the fixed rings and rotating rings being connected by a limiting component, and the fixed rings and the corresponding clamping plates being connected by a sliding component.

[0004] In this existing design, although the infrared temperature sensor can be quickly clamped by the operator using clamping components—specifically, the operator inserts the infrared temperature sensor into two fixing rings, placing it between several clamping plates, and then quickly clamps the infrared temperature sensor by rotating the connecting rod—the clamping process is convenient and quick, achieving rapid clamping of the infrared temperature sensor and improving the practicality of the constant temperature testing device. However, manually rotating the connecting rod to drive the clamping components to clamp the sensor is not convenient for fixing the connecting rod, requiring manual fixing of the connecting rod. This can easily lead to excessive or insufficient clamping force, resulting in sensor damage or inaccurate testing.

[0005] To address this issue, a temperature sensor performance output testing device and its testing method are designed. Summary of the Invention

[0006] To address the problems mentioned in the background section, this invention provides a temperature sensor performance output testing device and method, which features easy adjustment of clamping force and avoids damage to the sensor.

[0007] The present invention adopts the following technical solution: it includes a testing device body, on which a plurality of clamping components are provided. Each clamping component includes a base, a first support rod, and a second support rod. The first support rod and the second support rod are both installed on the top surface of the base, which is installed on the top surface of the testing device body. A first fixed plate is fixedly installed at the top of the first support rod, and a second fixed plate is fixedly installed at the top of the second support rod. Turntables are rotatably connected to the sides of both the first and second fixed plates. A cavity is formed inside the turntable, and a limiting groove is formed on the surface of the turntable. A clamping block is slidably connected inside the cavity, and a connecting block is installed on the surface of the clamping block. The connecting block is slidably connected inside the limiting groove. A slot is formed on the surface of the first fixed plate. The turntables on the sides of the first and second fixed plates are connected by a first connecting rod, and a locking component is provided on the surface of the first connecting rod.

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

[0009] As a preferred embodiment of the temperature sensor performance output testing device of the present invention, both ends of the slide rod are fixedly equipped with blocks, and both the blocks and the slide rod are rectangular in shape.

[0010] In 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] In a preferred embodiment of the temperature sensor performance output testing device of the present invention, one end of the spring is fixedly connected to the side of the short block, and the other end of the spring is fixedly connected to the side of the extension plate.

[0012] As a preferred embodiment of the 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, and a counterweight is fixedly mounted on the surface of the second connecting rod, wherein the first connecting rod and the second connecting rod are symmetrically distributed.

[0013] As a preferred embodiment of the temperature sensor performance output testing device of the present invention, the shape and size of the card block and the card slot are matched, and the card slot is distributed in a circumferential array on the surface of the first fixed plate.

[0014] As a preferred embodiment of the temperature sensor performance output testing 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 embodiment of the 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, and a groove is formed on the surface of the auxiliary support rod. A ball bearing is rolled inside the groove.

[0016] As a preferred embodiment of the temperature sensor performance output testing device of the present invention, the number of grooves is several groups, and the several groups of grooves are distributed at equal intervals on the surface of the auxiliary support rod, and the ball bearings are in contact with the surface of the turntable.

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

[0018] S1. Before testing, the staff first inserts the temperature sensor between the first fixed plate and the second fixed plate, and uses the locking component to release the limit of the turntable. Specifically, by pulling the extension plate, the extension plate slides on the surface of the short rod, and at the same time the extension rod compresses 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 disengages from the inside of the slot.

[0019] S2. At this time, the temperature sensor is clamped and fixed using the clamping assembly. The turntable is unlocked and the first connecting rod is rotated in the same direction as the slot. The first connecting rod drives the turntable to rotate. At the same time, the turntable drives the second connecting rod and the counterweight on its surface to rotate. When the turntable rotates, friction occurs between its surface and the ball, which in turn 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. When the limiting groove rotates, it squeezes the connecting block. After the connecting block is squeezed, it drives the clamping block to move. At this time, under the cooperative 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 component. Specifically, after the clamping block is fixed in position, the extension plate is released and pulled. Since the side 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 card block to re-insert into the card slot. At this time, since the second connecting rod and the first connecting rod are symmetrically arranged, the counterweight on the surface of the second connecting rod applies a force opposite to the direction of movement of the first connecting rod. That is, the counterweight drives the turntable to move in the opposite direction to the card slot. Therefore, the counterweight can make the card block further engage with the card slot.

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

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

[0024] In this invention, a clamping assembly and a locking assembly are provided. The first connecting rod drives the turntable to rotate, thereby clamping the sensor with the clamping block. This allows the operator to quickly fix the clamping block and easily control the clamping force by adjusting the position of the locking block and the locking slot, preventing damage to the sensor or inaccurate testing due to excessive or insufficient clamping force. An auxiliary support rod, a groove, and a ball bearing are also provided. The auxiliary support rod improves the support stability of the second fixed plate, and the ball bearing is brought into contact with the turntable on the side of the second fixed plate, reducing the friction between the turntable and the auxiliary support rod and preventing jamming when rotating the turntable.

[0038] To better understand the above-mentioned objectives, features, and advantages of the present invention, the present invention will be further described below in conjunction with the accompanying drawings and embodiments. It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be combined with each other.

[0039] Numerous specific details are set forth in the following description in order to provide a full understanding of the invention. However, the invention may also be practiced in other ways than those described herein, and therefore the invention is not limited to the specific embodiments disclosed in the following specification.

[0040] Example 1

[0041] In the existing technology, the existing temperature sensor constant temperature testing device includes a main body 1. This testing device also has several clamping components on the constant temperature testing device. The clamping components include two support rods, each with a fixed ring fixed at its top. Each fixed ring has a rotating ring rotatably mounted on it. Several movable clamping plates are provided between each fixed ring and its corresponding rotating ring. The two rotating rings are fixedly connected by a connecting rod. The clamping plates between the fixed rings and the rotating rings are moved by a driving component. The fixed rings and rotating rings are connected by a limiting component. The fixed rings and the corresponding clamping plates are connected by a sliding component. By setting up the clamping components, the operator can quickly clamp the infrared temperature sensor. Specifically, the operator inserts the infrared temperature sensor into the two fixed rings, placing the infrared temperature sensor between the clamping plates, and then quickly clamps the infrared temperature sensor by rotating the connecting rod. The clamping process is convenient and quick, realizing rapid clamping of the infrared temperature sensor and improving the practicality of the constant temperature testing device.

[0042] This application incorporates the aforementioned prior art, such as Figures 1-9 As shown, the present invention provides a technical solution: a temperature sensor performance output testing device. The main body 1 of the testing device is provided with several clamping components 2. Each clamping component 2 includes a base 201, a first support rod 202, and a second support rod 203. Both the first support rod 202 and the second support rod 203 are mounted on the top surface of the base 201. The base 201 is mounted on the top surface of the main body 1 of the testing device. A first fixing plate 204 is fixedly mounted on the top end of the first support rod 202, and a second fixing plate 205 is fixedly mounted on the top end of the second support rod 203. The first fixing plate 204 and the second fixing plate 205... The sides of the fixed plate 205 are rotatably connected to turntables 206. The turntables 206 have cavities 207 inside and limit grooves 208 on their surface. Clamping blocks 209 are slidably connected inside the cavities 207. Connecting blocks 210 are mounted on the surface of clamping blocks 209 and slidably connected inside the limit grooves 208. The surface of the first fixed plate 204 has a slot 211. The turntables 206 on the sides of the first fixed plate 204 and the second fixed plate 205 are connected by a first connecting rod 212. A locking component 3 is provided on the surface of the first connecting rod 212.

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

[0044] In this implementation scheme: a clamping assembly 2 is provided. Rotating the first connecting rod 212 drives the turntable 206 to rotate, and the turntable 206 drives the clamping block 209 to slide within the cavity 207. At the same time, the sliding trajectory of the clamping block 209 is limited by the connecting block 210 and the limiting groove 208. The clamping block 209, which slides along a specific motion trajectory, can clamp the sensor, making it easy 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 locking block 306 and the locking groove 211, so as to avoid damage to the sensor or inaccurate testing due to excessive or insufficient clamping force. A locking assembly 3 is also provided. The locking block 306 engages with the locking groove 211 to fix the rotation angle of the turntable 206, eliminating the need for manual fixing and reducing the probability of testing errors.

[0045] Combining the above solutions:

[0046] Furthermore:

[0047] like Figures 4 to 6 As shown;

[0048] To prevent the slider 302 from rotating, in an optional embodiment, both ends of the slide rod 301 are fixedly equipped with stops 307, both of which are rectangular in shape. The stops 307 can be connected to the slide rod 301 by bolts or welding, ensuring the stability of the stops 307 during installation and smooth operation. The stops 307 can be made of stainless steel or aluminum alloy, which have high strength and corrosion resistance.

[0049] In this embodiment, both the stop 307 and the slide bar 301 are set as rectangles to prevent the slider 302 from rotating on its own when it moves on the surface of the slide bar 301, thus 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] Furthermore:

[0052] like Figures 4 to 6 As shown;

[0053] To facilitate the removal of the locking block 306, in an optional embodiment, an extension plate 308 is fixedly mounted on the side of the slider 302, and the extension plate 308 is slidably connected to the surface of the short rod 304. The extension plate 308 can be connected to the slider 302 by bolts or welding, ensuring the installation stability and smooth operation of the extension plate 308. The extension plate 308 can be made of stainless steel or aluminum alloy, which has the characteristics of 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 bar 301. The extension plate 308 increases the contact area between the operator's hand and the slider 302, making it easier for the slider 302 to remove the card block 306 from the card slot 211, thus improving the locking efficiency.

[0055] Combining the above solutions:

[0056] Furthermore:

[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, ensuring 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 pressure and, under its own elastic force, can drive 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 locking block 306 is pushed into the slot 211, so that the locking block 306 can automatically reset after the extension plate 308 is released.

[0060] Combining the above solutions:

[0061] Furthermore:

[0062] like Figure 7 As shown;

[0063] To further secure the locking block 306 within the slot 211, in an optional embodiment, a second connecting rod 213 is fixedly mounted on the surface of the first fixing plate 204, and 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 distributed. The second connecting rod 213 can be connected to the first fixing plate 204 by bolts or welding to ensure the installation stability and smooth operation of the second connecting rod 213. The material of the second connecting rod 213 can be stainless steel or aluminum alloy, which has the characteristics of high strength and corrosion resistance.

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

[0065] Combining the above solutions:

[0066] Furthermore:

[0067] like Figures 1 to 7 As shown;

[0068] To lock the turntable 206, in an optional embodiment, the shape and size of the locking block 306 and the locking slot 211 are matched, and the locking slot 211 is distributed in a circumferential array on the surface of the first fixing disk 204. The matching shape and size of the locking block 306 and the circumferential array distribution of the locking slot 211 on the surface of the first fixing disk 204 facilitates adjustment of the positions of the locking block 306 and the locking slot 211, thereby enabling the turntable 206 to be fixed when rotated at different angles.

[0069] Combining the above solutions:

[0070] Furthermore:

[0071] like Figures 4 to 5 As shown;

[0072] To enhance the strength of the locking block 306, in one optional embodiment, the locking block 306 is hollow, and a reinforcing rib 309 is fixedly installed inside the locking block 306. The reinforcing rib 309 can be connected to the locking block 306 by bolts or welding, ensuring the installation stability and smooth operation of the reinforcing rib 309. The reinforcing rib 309 can be made of stainless steel or aluminum alloy, which have the characteristics of high strength and corrosion resistance.

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

[0074] Combining the above solutions:

[0075] Furthermore:

[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 installed on the top surface of the base 201. The top end of the auxiliary support rod 215 is arc-shaped, and a groove 216 is formed on the surface of the auxiliary support rod 215. A ball bearing 217 is rolled inside the groove 216. The auxiliary support rod 215 can be connected to the base 201 by bolts or welding to ensure 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 the characteristics of 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 prevent it from affecting the clamping effect of the sensor.

[0079] Combining the above solutions:

[0080] Furthermore:

[0081] like Figures 7 to 9 As shown;

[0082] To reduce friction between the turntable 206 and the auxiliary support rod 215, in an optional embodiment, the grooves 216 are arranged in several groups, with equal spacing between the groups of grooves 216 on the surface of the auxiliary support rod 215, and the ball bearings 217 are in contact with the surface of the turntable 206. The ball bearings 217 can be connected to the grooves 216 by bolts or welding, ensuring the installation stability and smooth operation of the ball bearings 217. The ball bearings 217 can be made of stainless steel or aluminum alloy, which have high strength and corrosion resistance.

[0083] In this embodiment: a groove 216 is formed on the surface of the auxiliary support rod 215, and a ball bearing 217 is set inside the groove 216. By the contact between the ball bearing 217 and the surface of the turntable 206, the friction between the turntable 206 and the auxiliary support rod 215 can be reduced, and the jamming of the turntable 206 during rotation can be avoided, thus affecting the clamping effect of the sensor.

[0084] Example 2

[0085] The temperature sensor performance output testing device of this application was described in detail in Embodiment 1. This embodiment provides a testing method for the above-mentioned device, which specifically includes the following steps:

[0086] S1. Before testing, the staff first inserts the temperature sensor between the first fixed plate 204 and the second fixed plate 205, and uses the locking component 3 to release the limit of the turntable 206. Specifically, by pulling the extension plate 308, the extension plate 308 slides on the surface of the short rod 304. At the same time, 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 locking block 306 disengages from the inside of the slot 211.

[0087] S2. At this time, the temperature sensor is clamped and fixed using the clamping assembly 2. The turntable 206 is unlocked and the first connecting rod 212 rotates in the same direction as the 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 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. When the limiting groove 208 rotates, it squeezes the connecting block 210. 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 turntable 206 is locked again by the locking component 3. Specifically, after the clamping block 209 is fixed in position, the extension plate 308 is released and pulled. Since the side 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 locking block 306 to re-insert into the slot 211. At this time, 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 opposite to the direction of movement of the first connecting rod 212. That is, the counterweight block 214 drives the turntable 206 to move in the opposite direction to the slot 211. Therefore, the counterweight block 214 can make the locking block 306 further engage with the slot 211.

[0090] S5. Then, the temperature sensor can be tested using the main body 1 of the testing device.

[0091] The above description is merely a preferred embodiment of the present invention and is not intended to limit the present invention in any other way. Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments for application in other fields. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of the present invention without departing from the scope of the present invention shall still fall within the protection scope of the present invention.

3. The temperature sensor performance output testing device according to claim 1, characterized in that: The shape and size of the card block (306) and the card slot (211) are matched, and the card slot (211) is distributed in a circumferential array on the surface of the first fixing plate (204).

4. The temperature sensor performance output testing device according to claim 1, characterized in that: The card block (306) is hollow, and a reinforcing rib (309) is fixedly installed inside the card block (306).

5. The temperature sensor performance output testing device according to claim 1, characterized in that: An auxiliary support rod (215) is fixedly installed on the top surface of the base (201). The top end of the auxiliary support rod (215) is arc-shaped. A groove (216) is opened on the surface of the auxiliary support rod (215). A ball bearing (217) is rolled inside the groove (216).

6. The temperature sensor performance output testing device according to claim 5, characterized in that: The grooves (216) are in several groups, and the grooves (216) are evenly distributed on the surface of the auxiliary support rod (215). The balls (217) and the turntable (206) are in contact with each other.

7. The test method using the temperature sensor performance output test device as described in claim 6, characterized in that: Includes the following steps: S1. Before testing, the staff first inserts the temperature sensor between the first fixed plate (204) and the second fixed plate (205), and uses the locking component (3) to release the limit of the turntable (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 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 card block (306) disengages from the inside of the card 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 same direction as the 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 (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). S3. At the same time, the turntable (206) drives the limiting groove (208) on its surface to rotate. When the limiting groove (208) rotates, it squeezes the connecting block (210). After the connecting block (210) is squeezed, it drives the clamping block (209) to move. At this time, under the cooperative 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) fixes the temperature sensor, the turntable (206) is locked again by the locking component (3). Specifically, after the clamping block (209) is fixed in position, the extension plate (308) is released and pulled. Since the side 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 locking block (306). When the second connecting rod (213) is reinserted 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) applies a force opposite to the direction of movement of the first connecting rod (212). That is, the counterweight (214) drives the turntable (206) to move in the opposite direction to the slot (211). Therefore, the counterweight (214) can make the card block (306) further engage with the slot (211). S5. Subsequently, the temperature sensor can be tested using the main body (1) of the test device.
