Description

Technical Field

[0001] This invention relates to the field of sensor detection technology, and in particular to a sensor aging detection device. Background Technology

[0002] As the core sensing element in various industrial monitoring and intelligent control systems, the stability of the sensor's working state directly determines the accuracy of the monitoring data and the reliability of the system operation. Usually, sensors need to be aged before leaving the factory to prevent instability due to factors such as surface structure before leaving the factory. The performance of the aged sensor can be more accurate and stable.

[0003] However, traditional aging testing devices rely on manual inspection when performing aging tests on sensors. Manual inspection consumes manpower and resources, and the test results are also affected by the operator's skill level. Manual operation requires offline disassembly, which is cumbersome. In addition, traditional automated testing methods require the test board to be moved out of the aging rack. This means that after the robotic arm finishes testing the sensors on the current test board, it must wait for the test board to return to its original position before it can move forward to test the next target. It is impossible to continue the testing work immediately after the test is completed. Moreover, after the test is completed, the sensors on the test board need to be replaced, and the test board needs to be moved out again to replace the sensors on it to facilitate the next round of aging work. When moving the test board out for testing, the sensors on the test board that are close to the aging rack are not convenient for the robotic arm to pick up. Summary of the Invention

[0004] The purpose of this invention is to solve the problems of low detection efficiency caused by manual inspection in existing aging detection devices and the low efficiency of traditional automated detection methods, which affect the material handling of robotic arms. Therefore, a sensor aging detection device is proposed.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A sensor aging detection device includes a base, an aging detection component, and two sets of adjustment components. The aging detection component includes several aging frames fixedly installed on the base. Several walking mechanisms are installed on the inner side of the aging frames, and a main frame is rotatably connected to the walking mechanism.

[0007] The adjustment assembly includes two electric push rods 1 mounted on the aging rack. One end of each electric push rod 1 is fixedly connected by a fixing plate 1. An electric push rod 2 is provided on the outside of the fixing plate 1. A serrated plate that is slidably connected to the fixing plate is provided on the output end of the electric push rod 2. A gear transmission component is installed on the main frame.

[0008] The first walking mechanism acts on the main frame to be translated and pushed out during the inspection. The serrated plate is engaged with the gear transmission component after being pushed out by the first electric push rod to constrain the angular position of the main frame. The second electric push rod acts on the serrated plate and the gear transmission component to rotate the main frame ninety degrees and completely expose the area to be inspected.

[0009] As a further description of the above technical solution:

[0010] The aging detection component also includes a mounting frame that is slidably disposed inside the main frame. A sensor aging test plate is fixedly disposed inside the mounting frame. Several sensor bodies are disposed on the sensor aging test plate, and four elastic blocks for limiting the mounting frame are installed on the main frame.

[0011] As a further description of the above technical solution:

[0012] The base is provided with a robotic arm assembly for detecting the sensor body. The robotic arm assembly includes a track base mounted on the base, a second walking mechanism is provided on the track base, the robotic arm body is mounted on the second walking mechanism, and a clamping mechanism and a detection mechanism are installed at one end of the robotic arm body.

[0013] As a further description of the above technical solution:

[0014] The walking mechanism is provided with a limiting component for constraining the angular position of the main frame. The limiting component includes two fixing blocks 1 fixedly installed on the walking mechanism and two fixing blocks 2 fixedly installed on the main frame. A rod is inserted through the fixing block 1. A baffle is fixedly installed on the outside of the rod, and a spring is provided between the baffle and the fixing block 1. The fixing block 2 is penetrated by the rod.

[0015] As a further description of the above technical solution:

[0016] The horizontal height of the baffle and the serrated plate are matched, and the spring is located on the periphery of the corresponding insertion rod.

[0017] As a further description of the above technical solution:

[0018] The aging rack is equipped with two support plates, which are used to support the main frame after the angle is adjusted.

[0019] As a further description of the above technical solution:

[0020] The aging rack is divided into upper and lower layers, and each layer has several slide rails on its upper and lower surfaces. The walking mechanism is adapted to match the slide rails.

[0021] As a further description of the above technical solution:

[0022] The detection mechanism consists of an infrared camera assembly and a temperature acquisition probe.

[0023] In summary, due to the adoption of the above technical solution, the beneficial effects of the present invention are:

[0024] By coordinating the robotic arm components, aging detection components, limit components, and adjustment components, the device's detection efficiency can be improved. Compared to traditional manual inspection, it avoids errors in detection results caused by human error and can directly move to the next target after completing the detection of the current target. Compared to traditional automated detection methods, it avoids the time wasted waiting for parts to retract and solves the problem of difficult material retrieval in special positions with traditional robotic arms. The walking mechanism, in conjunction with the main frame, allows the main frame to be pushed out of the aging rack for detection as needed, or moved back into the aging rack as needed. The insertion rod constrains the main frame, ensuring that it does not rotate when pushed out or moved back. The electric push rod engages the serrated plate and gear transmission components, and under the action of the electric push rod, the pushed-out main frame can rotate, fully exposing the sensor body for subsequent detection and material retrieval. The support plate supports the rotated main frame, and the elastic locking block keeps the mounting frame inside the main frame, preventing displacement of the mounting frame when the main frame moves or rotates.

[0044] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of the present invention.

[0045] like Figure 1 - Figure 17 As shown, the present invention provides:

[0046] A sensor aging detection device includes a base 10 and an aging detection component 20. The aging detection component 20 includes several aging frames 21 fixedly installed on the base 10. Several walking mechanisms 22 are installed on the inner side of the aging frames 21. A main frame 23 is rotatably connected to the walking mechanism 22. The aging detection component 20 also includes a mounting frame 24 slidably disposed on the inner side of the main frame 23. A sensor aging test plate 25 is fixedly disposed on the inner side of the mounting frame 24. Several sensor bodies 26 are disposed on the sensor aging test plate 25. Four elastic blocks 27 for limiting the mounting frame 24 are installed on the main frame 23. The aging frames 21 are divided into upper and lower layers. Several slide rails are disposed on the upper and lower surfaces of each layer. The walking mechanism 22 and the slide rails are adaptively matched.

[0047] Specifically, the aging rack 21 is made of high-strength aluminum alloy and has an overall frame structure. Anti-slip and shock-absorbing pads are installed at the bottom of the aging rack 21 to ensure stable placement and prevent vibration during operation that could cause sensor displacement or data distortion. The aging rack 21 has two layers, each with several equally spaced slide rails. Each layer of the aging rack 21 is equipped with an independent power supply interface and data interface. A main power supply unit is installed on the aging rack 21 to provide stable power to the aging rack 21, sensor aging test board 25, and various testing modules. This allows multiple sensor bodies 26 to undergo aging testing simultaneously, significantly improving testing efficiency. The walking mechanism 22 moves the main frame 23 along the slide rails. The sensor aging test board 25 is the supporting component for the sensor body 26 and is precisely fitted to the mounting frame 24 within the main frame 23. The mounting frame 24 can be manually pushed into the inner side of the main frame 23 from the outside, with the position constrained by the elastic locking block 27. Simultaneously, the sensor aging test board 25 can be pushed out from the inside of the aging rack 21 via the walking mechanism 22.

[0048] The sensor aging test board 25 adopts a high-precision voltage regulation circuit design. It can adjust the output voltage and current according to the rated voltage and current parameters of the sensor body 26 under test through the power supply control mechanism to accurately adapt to the power supply requirements of the sensor body 26. The sensor aging test board 25 has built-in overload, short circuit and over-temperature protection circuits, which can monitor the power supply status in real time. When a power supply abnormality occurs, the power supply of the corresponding channel is immediately cut off to avoid damage to the sensor body 26 and the testing equipment. At the same time, the sensor aging test board 25 has a reserved data acquisition interface, which is automatically connected to the data interface of the aging rack 21. It can collect power supply voltage and current data in real time and transmit them to the back-end processing and analysis module for comprehensive judgment of the aging status of the sensor body 26 in combination with thermal characteristic data.

[0049] The sensor bodies 26 are evenly spaced on the sensor aging test board 25. The sensor aging test board 25 directly provides stable power to the sensor bodies 26 without the need for additional power supply lines. After powering on, the sensor bodies 26 can be aged.

[0050] When the main frame 23 needs to be pushed out, in the initial state, the traveling mechanism 22 is activated to move the main frame 23 on the slide rail of the aging frame 21 until the traveling mechanism 22 moves from one end of the slide rail to the other and stops. At this time, the main frame 23 is pushed out horizontally, achieving the desired result. Figures 9-10 The state shown is as follows. In this state, refer to Figure 11 As shown, the serrated plate 44 and the gear transmission component 45 are not meshed.

[0051] like Figures 4-16 As shown, in order to solve the problem that the main frame 23 can rotate after being pushed out, the device is also equipped with two sets of adjustment components 40.

[0052] The adjustment assembly 40 includes two electric push rods 41 mounted on the aging rack 21. One end of each electric push rod 41 is fixedly connected to a fixing plate 42. An electric push rod 43 is provided on the outside of the fixing plate 42. A serrated plate 44 is provided at the output end of the electric push rod 43 and is slidably connected to the fixing plate 42. A gear transmission component 45 is installed on the main frame 23. The walking mechanism 22 acts on the main frame 23 to be pushed out during testing. The serrated plate 44 is engaged with the pushed-out gear transmission component 45 under the action of the electric push rods 41 to constrain the angular position of the main frame 23. The electric push rod 43 acts on the serrated plate 44 and the gear transmission component 45 to rotate the main frame 23 by 90 degrees and fully expose the area to be tested.

[0053] Specifically, when the main frame 23 reaches such Figures 9-10 After the state shown, in this state, refer to Figure 11The serrated plate 44 is not engaged with the gear transmission component 45, and one end of the insert rod 53 is located in the fixing block 52, limiting the main frame 23. When the main frame 23 needs to rotate, the electric push rod 41 is activated to retract the fixing plate 42. The fixing plate 42 moves the serrated plate 44 closer to the gear transmission component 45. During this approach, the serrated plate 44 contacts the baffle 54 and presses it towards the fixing block 51, compressing the spring 55 until the serrated plate 44 engages with the gear transmission component 45 and stops. At this point, refer to Figures 14-16 One end of the insertion rod 53 is pulled out from the fixing block 2 52 to release the constraint on the main frame 23. The electric push rod 2 43 is activated, causing the serrated plate 44 to move in the opposite direction of the electric push rod 2 43. The serrated plate 44 and the gear transmission component 45 mesh, thereby causing the main frame 23 to rotate until the main frame 23 rotates 90 degrees and then stops. At this time, the device achieves the desired state. Figures 12-13 As shown, several sensor bodies 26 within the main frame 23 are fully exposed, with no obstacles or interference in the surrounding area, and will not affect subsequent detection and material handling.

[0054] Two support plates 11 are installed on the aging frame 21. The support plates 11 are used to support the main frame 23 after the angle is adjusted.

[0055] When the main frame 23 is rotated 90 degrees, it is supported by the support plate 11, which can enhance the stability of the device during the detection process.

[0056] like Figure 3 , Figure 4 , Figure 6 As shown, in order to solve the problem that the main frame 23 does not rotate when it is pushed out and put away, the walking mechanism 22 is provided with a limiting component 50 for constraining the angular position of the main frame 23.

[0057] The limiting component 50 includes two fixing blocks 51 fixedly installed on the walking mechanism 22 and two fixing blocks 52 fixedly installed on the main frame 23. A rod 53 is provided through the fixing block 51. A baffle 54 is fixedly installed on the outside of the rod 53. A spring 55 is provided between the baffle 54 and the fixing block 51. The fixing block 52 is penetrated by the rod 53. The horizontal height of the baffle 54 and the serrated plate 44 are matched. The spring 55 is located on the periphery of the corresponding rod 53.

[0058] Specifically, in the initial state, one end of the insert rod 53 is inserted into the fixing block 52 to constrain the position of the main frame 23. During the retraction of the electric push rod 41, one end of it moves along with the fixing plate 42. The fixing plate 42, along with the serrated plate 44, moves closer to the gear transmission component 45. During this approach, the serrated plate 44 contacts the baffle 54 and presses it towards the fixing block 51, compressing the spring 55 until the serrated plate 44 and the gear transmission component 45 engage and connect, at which point the reference... Figures 14-16 One end of the insertion rod 53 is pulled out from the second fixing block 52 to release the constraint on the main frame 23. Conversely, after the test is completed, the main frame 23 is rotated back to the initial position by the second electric push rod 43, and then the second fixing plate 42 is returned to the initial position by the first electric push rod 41. The spring 55 loses pressure and rebounds with the baffle 54 and the insertion rod 53, so that one end of the insertion rod 53 returns to the second fixing block 52 to re-constrain the main frame 23.

[0059] like Figure 1 , Figure 2 , Figure 17 As shown, in order to solve the problem of real-time detection and material handling of the sensor body 26, a robotic arm assembly 30 for detecting the sensor body 26 is provided on the base 10.

[0060] The robotic arm assembly 30 includes a track base 31 mounted on the base 10. A second walking mechanism 32 is provided on the track base 31. A robotic arm body 33 is mounted on the second walking mechanism 32. A clamping mechanism 34 and a detection mechanism 35 are installed at one end of the robotic arm body 33. The detection mechanism 35 consists of an infrared camera assembly and a temperature acquisition probe.

[0061] Specifically, a high-precision track base 31 is set parallel to the bottom of several aging racks 21. The track base 31 provides a stable and precise movement path for the robotic arm body 33. Under the action of the second walking mechanism 32, the robotic arm body 33 can move precisely along the track base 31 to achieve full coverage monitoring of the sensor bodies 26 on the sensor aging test board 25 of each layer and position of the aging rack 21. The front end of the robotic arm body 33 integrates a detection mechanism 35 consisting of an infrared camera assembly and a temperature acquisition probe. The infrared camera assembly realizes real-time image acquisition of the heat distribution and temperature changes of the sensor body 26 during operation. The temperature acquisition probe is a high-precision thermal sensing element, which can realize high-frequency and high-precision acquisition of single-point temperature in the core area of ​​the sensor. The two work together to form "thermal imaging surface temperature + single-point precise temperature". The dual temperature acquisition system provides multi-dimensional data for temperature tracking. If a sensor body 26 is determined to be faulty, the clamping mechanism 34 on the robotic arm body 33 will pick up the material. The detection mechanism 35 at the front end of the robotic arm body 33 will detect the temperature change of the sensor body 26 and detect the aging temperature distribution of the sensor body 26 at each position on the sensor aging test board 25 during power-on aging.

[0062] When the device reaches such Figures 12-13 In the indicated state, the second walking mechanism 32 is activated, causing the robotic arm body 33 to move to the position directly opposite the rotated main frame 23 and stop. At this time, the robotic arm body 33, in conjunction with the detection mechanism 35, can be used to detect several sensor bodies 26 on the sensor aging test plate 25. When it is necessary to remove the unqualified sensor body 26 from the sensor aging test plate 25, the robotic arm body 33, in conjunction with the clamping mechanism 34 and the detection mechanism 35, can remove it. Since the rotated main frame 23 exposes several sensor bodies 26, there is no problem of difficulty in picking up sensor bodies 26 near the aging rack 21. After detecting several sensor bodies 26 on the current sensor aging test plate 25, the second walking mechanism 32 can be activated directly to continue moving forward and detect the target on the next aging rack 21.

[0063] Furthermore, before the current sensor bodies 26 on the current sensor aging test board 25 are tested, a main frame 23 on the next aging rack 21 needs to be pushed out and rotated in advance. This allows the walking mechanism 2 32 to be started so that the robotic arm body 33 can be moved to the corresponding position for subsequent testing. When the device tests the sensor bodies 26 on the next aging rack 21, the operator can directly remove the mounting frame 24 that has just been tested and reinstall a new mounting frame 24 to replace the sensor body 26. This facilitates the next round of aging work for the tested sensor bodies 26. By testing first and then replacing the parts at the position where the previous test was completed, the sensor bodies 26 on several aging racks 21 can be tested and replaced at the same time, which is convenient for the next round of aging test work for the sensor bodies 26.

[0064] Working principle:

[0065] Figure 1 , Figure 17 This is the initial state of the device. In this state, the sensor aging test board 25 performs aging work on the sensor body 26, and the second walking mechanism 32 is located at one end of the track base 31. The insertion rod 53 is inserted into the second fixing block 52 to constrain the position of the main frame 23. The first electric push rod 41 is in the extended state, and the second electric push rod 43 is in the retracted state.

[0066] When the device needs to push out the main frame 23: In the initial state, the traveling mechanism 22 is activated to move the main frame 23 on the slide rail of the aging rack 21 until the traveling mechanism 22 moves from one end of the slide rail to the other and stops. At this time, the main frame 23 is pushed out horizontally, achieving the desired result. Figures 9-10 The state shown is as follows. In this state, refer to Figure 11 As shown, the serrated plate 44 and the gear transmission component 45 are not meshed. Before the sensor body 26 is aged, the mounting frame 24 needs to be manually pushed into the main frame 23. When the mounting frame 24 is fully pushed in, it will be locked by the elastic block 27 to prevent it from sliding during subsequent movement. The installation and removal of the mounting frame 24 are all done manually.

[0067] When the device needs to rotate the main frame 23: when the main frame 23 reaches the following... Figures 9-10 After the state shown, in this state, refer to Figure 11The serrated plate 44 is not engaged with the gear transmission component 45, and one end of the insert rod 53 is located in the fixing block 52, limiting the main frame 23. When the main frame 23 needs to rotate, the electric push rod 41 is activated to retract the fixing plate 42. The fixing plate 42 moves the serrated plate 44 closer to the gear transmission component 45. During this approach, the serrated plate 44 contacts the baffle 54 and presses it towards the fixing block 51, compressing the spring 55 until the serrated plate 44 engages with the gear transmission component 45 and stops. At this point, refer to Figures 14-16 One end of the insertion rod 53 is pulled out from the fixing block 2 52 to release the constraint on the main frame 23. The electric push rod 2 43 is activated, causing the serrated plate 44 to move in the opposite direction of the electric push rod 2 43. The serrated plate 44 and the gear transmission component 45 mesh, thereby causing the main frame 23 to rotate until the main frame 23 rotates 90 degrees and then stops. At this time, the device achieves the desired state. Figures 12-13 As shown, several sensor bodies 26 within the main frame 23 are fully exposed, with no obstacles around them interfering with the operation, and will not affect subsequent detection and material handling.

[0068] When the device needs to detect the sensor body 26: when the device reaches the following... Figures 12-13In the indicated state, the second walking mechanism 32 is activated, causing the robotic arm body 33 to move to the position directly opposite the rotated main frame 23 and stop. At this point, the robotic arm body 33, in conjunction with the detection mechanism 35, can then inspect several sensor bodies 26 on the sensor aging test plate 25. When it is necessary to remove a defective sensor body 26 from the sensor aging test plate 25, the robotic arm body 33, in conjunction with the clamping mechanism 34 and the detection mechanism 35, can remove it. Since the rotated main frame 23 exposes several sensor bodies 26, there is no problem of difficulty in removing sensor bodies 26 near the aging rack 21. After inspecting several sensor bodies 26 on the current sensor aging test plate 25, the second walking mechanism 32 can be activated directly to continue moving forward and inspecting the target on the next aging rack 21. Before the current sensor bodies 26 on the current sensor aging test board 25 are tested, a main frame 23 on the next aging rack 21 needs to be pushed out and rotated in advance. This makes it easier to start the walking mechanism 32 to directly move the robotic arm body 33 to the corresponding position for subsequent testing. When the device tests the sensor bodies 26 on the next aging rack 21, the staff can directly remove the mounting frame 24 that has just been tested and reinstall a new mounting frame 24 to replace the sensor body 26. This makes it easier for the tested sensor bodies 26 to undergo the next round of aging work. By testing first and then replacing the parts at the position after the previous test, the sensor bodies 26 on several aging racks 21 can be tested and replaced at the same time, which is convenient for the next round of aging test of the sensor bodies 26.
