[0004] With the development of industrial automation, the demand for intelligent and efficient sensor detection is increasing. Therefore, there is an urgent need for a sensor detection test bench that can achieve automated detection, classification, and cleaning to improve detection efficiency and accuracy while reducing labor costs.

[0026] The preferred embodiments of the present invention will be described below with reference to the accompanying drawings. It should be understood that the preferred embodiments described herein are for illustration and explanation only and are not intended to limit the present invention.

[0027] Please seeFigures 1-6 As an embodiment of this utility model, a sensor detection test bench includes a test bench 1, which includes a cabinet 101. An integrated control box 102 is fixedly installed on the cabinet 101. A sensor detection component 2 is installed inside the cabinet 101. The sensor detection component 2 includes a test box 201. Extension rods 204 are fixedly connected to the top two sides of the test box 201. A mounting ring 202 is installed above the test box 201. A sensor clamping component is installed on the mounting ring 202. A drive component 3 is installed on the cabinet 101 and connected to the mounting ring 202. A recycling and cleaning component 4 is installed inside the cabinet 101 on one side of the test box 201. The drive component 3 drives the sensor clamping component to move after detection. According to the sensor detection result, the sensor is recycled or cleaned and then re-detected. In actual use, different test boxes 201 are used to provide different experimental environments. When the detection end of the sensor moves into the test box 201, the test box 201 provides the corresponding environment for sensor detection.

[0028] The device enables automatic clamping, detection, and sorting of sensors, significantly improving detection efficiency. The recycling and cleaning component 4 allows for automatic cleaning and re-detection of defective sensors, reducing misjudgments caused by temporary malfunctions or foreign object interference, improving the reliability of detection results, and lowering manual intervention costs. It is suitable for sensor performance testing in industrial production and scientific research experiments.

[0029] Please see Figures 2-6 In another embodiment of the present invention, the sensor detection assembly 2 further includes a sensor connector 203, on one side of the bottom of the sensor connector 203, an elastic telescopic column 205 is fixedly connected, the telescopic end of the elastic telescopic column 205 is fixedly connected to the mounting ring 202, and the sensor connector 203 is connected to the electrical output end of the sensor.

[0030] The sensor clamping assembly includes a fixing block 210 fixedly mounted on a mounting ring 202, a movable column 209 slidably passing through the fixing block 210, a clamping plate 212 fixedly connected to one end of the movable column 209, and an elastic element 211 sleeved on the movable column 209 between the clamping plate 212 and the fixing block 210; a limiting plate 206 is fixedly connected to the inner wall of the mounting ring 202 on one side of the clamping plate 212, both the limiting plate 206 and the clamping plate 212 are set with an arc-shaped structure, and the limiting plate 206 and the clamping plate 212 are correspondingly set.

[0031] The movable column 209 is fixedly connected to the mounting rod 208 at the end away from the clamping plate 212. The bottom sides of the mounting rod 208 are fixedly connected to the electric telescopic column 207. The telescopic end of the electric telescopic column 207 is fixedly connected to the actuator head 213. The actuator head 213 is correspondingly set with the extension rod 204. The electric telescopic column 207 is connected to the integrated control box 102. When the sensor can be used normally and detects a signal, it can convert the signal into an electrical signal and transmit it to the integrated control box 102 through the sensor connector. After receiving the signal, the integrated control box 102 can control the electric telescopic column 207 to extend, thereby driving the actuator head 213 to move down. The downward movement of the actuator head 213 can correspond to the extension rod 204 in the lateral direction.

[0032] See Figures 2-3 The drive assembly 3 includes a fixed base 302 fixedly mounted on the cabinet 101. An electric push rod 301 is fixedly connected to one side of the fixed base 302. A movable block 303 is fixedly connected to the telescopic end of the electric push rod 301. A movable groove 306 is opened on the top of the cabinet 101. The movable block 303 is slidably mounted in the movable groove 306.

[0033] The bottom of the movable block 303 is fixedly connected to the hydraulic telescopic column 304, the telescopic end of the hydraulic telescopic column 304 is fixedly connected to the linkage frame 305, and the bottom end of the linkage frame 305 is fixedly connected to the sensor connector seat 203.

[0034] See Figure 2 The recycling and cleaning component 4 includes a finished product recycling box 401. A support plate frame 402 is fixedly connected to the side of the finished product recycling box 401 away from the experimental box 201. A sensor cleaning pad 403 is fixedly connected to the top of the support plate frame 402. The sensor cleaning pad 403 is correspondingly set with the sensor clamping component.

[0035] The end face of the cabinet 101 on one side of the experimental box 201 is rotatably connected to the cover plate 104. The cover plate 104 rotates to open and close the cabinet 101. The mounting shell 103 is fixedly connected to the cabinet 101. The drive component 3 is set inside the mounting shell 103, which can better protect the internal components.

[0036] In the implementation of this utility model, pulling the mounting rod 208 moves the clamping plate 212 at the end of the movable column 209, compressing the elastic element 211. The sensor to be tested is then placed between the clamping plate 212 and the limiting plate 206 within the fixed block 210. Releasing the mounting rod 208 causes the clamping plate 212 to move under the action of the elastic element 211, clamping and fixing the sensor together with the limiting plate 206. Then, the integrated control box 102 controls the hydraulic telescopic column 304 to move downwards, driving the sensor connector seat 203 downwards via the linkage frame 305. The bottom of the sensor moves into the experimental chamber 201, and the mounting ring 202 contacts the experimental chamber 201. As the sensor connector seat 203 continues to move downwards, it causes the elastic telescopic column 205 to retract, allowing the sensor connector seat 203 to connect with the sensor end. Under the action of the experimental chamber 201, a corresponding environmental simulation is performed. After the sensor detects the corresponding environment, if the sensor is fault-free, it can pass through the sensor connector seat 203. 3. The signal is sent to the integrated control box 102. The integrated control box 102 controls the electric telescopic column 207 to move the contact head 213 downward. The contact head 213 is laterally aligned with the extension rod 204. Conversely, if the sensor is faulty, the integrated control box 102 will not receive the signal. At this time, the electric telescopic column 207 will not extend. After the test is completed, the hydraulic telescopic column 304 will reset. Under the action of the electric push rod 301, it can drive the linkage frame 305 below to move through the movable block 303. The linkage frame 305 can drive the sensor to move through the mounting ring 202 below. During the movement, since the electric telescopic column 207 on the side of the qualified sensor has extended, the contact head 213 will contact the extension rod 204. Under the obstruction of the extension rod 204, the mounting rod 208 will drive the clamping plate 212 at the end of the movable column 209 to move. When the clamping plate 212 moves away from the limit plate 206, the sensor will fall into the finished product recycling box 401. This process realizes the recycling of qualified sensors.

[0037] If a sensor fails to extend because the electric telescopic column 207 does not extend, the trigger head 213 will not contact the extension rod 204 during movement, indicating that the sensor failed the first test. At this time, the linkage frame 305 drives the sensor to continue moving, and the bottom of the sensor will contact the sensor cleaning pad 403 to clean it. Then the electric push rod 301 retracts and drives the sensor to reset. The above test steps are repeated to perform the test again, preventing test failures caused by the sensor not properly plugging into the sensor connector 203 or foreign objects on the bottom of the sensor, and reducing test errors.

[0038] Finally, it should be noted that the above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
