Description

Technical Field

[0001] This utility model relates to the field of calibration equipment technology, and in particular to an integrated calibration platform for radiation thermometers. Background Technology

[0002] During the production and calibration of radiation thermometers, they must be compared and calibrated against a standard blackbody source to ensure their temperature measurement accuracy. This process requires a dedicated calibration platform to precisely fix and position the radiation thermometer (i.e., the calibration source), ensuring that its optical probe is strictly concentrically aligned with the target of the standard blackbody source.

[0003] Currently, conventional calibration platforms on the market typically consist of a simple lifting mechanism and a fixed structure for a single radiation thermometer. Their positioning primarily relies on manual operation: rough horizontal positioning (X and Y directions) is achieved through manual adjustment, followed by centering using the lifting mechanism (Z direction). This manual operation mode has significant limitations: First, positioning accuracy is low, relying entirely on the operator's experience and feel, making it difficult to guarantee repeatability and directly affecting the accuracy and reliability of calibration data; second, calibration efficiency is extremely low, as only one radiation thermometer can be installed and calibrated at a time, requiring manual disassembly and reinstallation after each calibration, making the entire process time-consuming and unsuitable for batch calibration needs.

[0004] Therefore, there is an urgent need in this field for a calibration platform that can achieve automated precision positioning and support continuous batch operations, so as to fundamentally solve the problems of low calibration accuracy and efficiency in existing technologies. Utility Model Content

[0005] The purpose of this invention is to provide an integrated calibration platform for radiation thermometers to solve the problems existing in the prior art, enabling automated precision positioning and supporting continuous batch operations.

[0006] To achieve the above objectives, this utility model provides the following solution: A radiation thermometer calibration integrated platform includes a platform body, a three-axis moving assembly, a rotating module, and an electronic control system. The rotating module is mounted on the three-axis moving assembly, which is mounted on the platform body. The rotating module has multiple stations for fixing calibration sources and can rotate around a rotation axis to switch stations. The three-axis moving assembly includes an X-axis moving module, a Y-axis moving module, and a Z-axis moving module for driving the rotating module to move in the X, Y, and Z directions. The electronic control system is signal-connected to the rotating module and the multi-directional moving modules for controlling the rotation of the rotating module and the movement of the three-axis moving assembly.

[0007] In an exemplary embodiment, the rotating module includes a rotating support frame, a rotating shaft, a rotating drive mechanism, and a workstation mounting assembly; the rotating shaft is drive-connected to the rotating drive mechanism and rotatably connected to the rotating support frame, and the workstation mounting assembly is fixedly mounted on the rotating shaft; a plurality of workstations are evenly arranged circumferentially on the workstation mounting assembly with the rotating shaft as the center.

[0008] In an exemplary embodiment, the workstation mounting assembly includes a mounting shaft and mounting brackets. The mounting shaft is fixedly sleeved on the outer periphery of the rotating shaft, and at least two mounting brackets are fixedly mounted on the mounting shaft along its axial direction. Each mounting bracket is provided with a plurality of workstations, which correspond one-to-one along the axial direction of the mounting shaft.

[0009] In one exemplary embodiment, each station of the mounting bracket is provided with a quick-release structure for quickly installing and removing the calibration source.

[0010] In an exemplary embodiment, the quick-release structure includes a V-shaped seat, an inverted V-shaped pressure block, a swivel screw, and a locking nut that cooperate with each other. The V-shaped seat and the inverted V-shaped pressure block surround and form a receiving cavity for accommodating the calibration source. The first ends of the V-shaped seat and the inverted V-shaped pressure block are hinged to each other, and the second end of the V-shaped seat is hinged to the swivel screw. The second end of the inverted V-shaped pressure block has a through hole for the swivel screw to pass through. The locking nut is used to cooperate with the swivel screw to lock the V-shaped seat and the inverted V-shaped pressure block with the calibration source installed.

[0011] In one exemplary embodiment, the rotary drive mechanism is a servo motor, and the rotation angle can be controlled by the electronic control system.

[0012] In an exemplary embodiment, the Z-direction movement module includes four sets of electric push rods vertically disposed on the upper surface of the platform body; the moving ends of the four sets of electric push rods are horizontally disposed on a first mounting platform, and the four sets of electric push rods are respectively located at the four corners of the first mounting platform.

[0013] In an exemplary embodiment, the Y-direction movement module includes two sets of linear guide rails arranged parallel to each other on the first mounting platform, and a servo motor for driving the linear guide rails to move; a second mounting platform is provided on the sliders of the two sets of linear guide rails.

[0014] In one exemplary embodiment, the X-direction movement module includes two sets of linear guide rails arranged parallel to each other on the second mounting platform, and a servo motor for driving the linear guide rails to move; a third mounting platform is provided on the sliders of the two sets of linear guide rails, and the rotation module is mounted on the third mounting platform.

[0015] In one exemplary embodiment, the electrical control system includes a PLC controller and has an operation interface for setting position parameters and rotation angle parameters.

[0016] The present invention achieves the following technical advantages over the prior art: 1. By setting up an electrically controlled X, Y, Z three-axis movement component, the traditional manual coarse positioning is completely replaced. This allows the radiation thermometer to perform programmed and digital precision movement in three-dimensional space, with positioning accuracy reaching millimeters or even sub-millimeter levels. This fundamentally eliminates human error and ensures the accuracy and consistency of each calibration, laying a solid foundation for obtaining highly reliable calibration data.

[0017] 2. By setting up a multi-station rotary module, radiation thermometers to be calibrated can be pre-installed at multiple stations within a calibration cycle. Through the automatic indexing rotation of the rotary module, each station can be sequentially and quickly switched to its working position for calibration. This achieves "one-time clamping, continuous measurement," shortening the effective working time from "calibration time + multiple setup / disassembly times" to "calibration time + one setup / disassembly time." Calibration efficiency is several times higher than that of a single-station platform, making it particularly suitable for large-scale production and high-throughput testing scenarios.

[0018] 3. By integrating precise positioning function—three-axis movement and efficient switching function—multi-station rotation into a compact platform and controlling it uniformly through an electric drive system, this integrated design is not only compact and space-saving, but more importantly, it lays the foundation for the automation and intelligence of the entire calibration process, reducing the labor intensity and skill requirements of operators.

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings. Those skilled in the art can easily understand other advantages and effects of the present utility model from the content disclosed in this specification. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.

[0022] The purpose of this invention is to provide an integrated calibration platform for radiation thermometers to solve the problems existing in the prior art, enabling automated precision positioning and supporting continuous batch operations.

[0023] To make the above-mentioned objectives, features and advantages of this utility model more apparent and understandable, the utility model will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0024] Please refer to Figures 1 to 4 This embodiment provides a radiation thermometer calibration integrated platform, including a platform body 1, a three-axis moving assembly, a rotating module 2, and an electronic control system 10. The rotating module 2 is mounted on the three-axis moving assembly, which is mounted on the platform body 1. The rotating module 2 has multiple stations for fixing the calibration source 0 and can rotate around the rotating axis 202 to switch stations. The three-axis moving assembly includes an X-direction moving module 3, a Y-direction moving module 4, and a Z-direction moving module 5, which are used to drive the rotating module 2 to move in the X, Y, and Z directions. The electronic control system 10 is signal-connected to the rotating module 2 and the multi-direction moving modules, and is used to control the rotation of the rotating module 2 and the movement of the three-axis moving assembly.

[0025] This embodiment integrates a three-axis moving assembly consisting of an X-axis moving module 3, a Y-axis moving module 4, and a Z-axis moving module 5, and a multi-station rotating module 2 to achieve precise positioning and rapid station switching of the calibration source 0 in three-dimensional space. The three-axis moving assembly and the multi-station rotating module 2 are uniformly controlled by the electronic control system 10, which improves the degree of automation, reduces manual intervention, and enhances accuracy and efficiency, thus solving the problems of single station, low positioning accuracy, and low calibration efficiency in existing radiation thermometer calibration platforms.

[0026] Specifically, the rotating module 2 includes a rotating support frame 201, a rotating shaft 202, a rotating drive mechanism 203, and a station mounting assembly; the rotating shaft 202 is connected to the rotating drive mechanism 203 and rotatedly connected to the rotating support frame 201, and the station mounting assembly is fixedly mounted on the rotating shaft 202; multiple stations are evenly arranged circumferentially on the station mounting assembly with the rotating shaft 202 as the center.

[0027] By employing a structural combination of a rotating support frame 201 and a rotating shaft 202, along with a rotating drive mechanism 203, the rotation process is ensured to be smooth and the angle controllable. Multiple workstations are evenly arranged circumferentially to ensure that each workstation can accurately align with the calibration light source after rotation.

[0028] In this embodiment, the rotary drive mechanism 203 adopts a servo motor. The servo motor, in conjunction with the encoder feedback, achieves high-precision angle control (±0.02°) through the electronic control system 10, ensuring that each station can be accurately aligned with the calibration light source.

[0029] The workstation mounting assembly includes a mounting shaft 204 and a mounting bracket 205. The mounting shaft 204 is fixedly sleeved on the outer periphery of the rotating shaft 202. At least two mounting brackets 205 are fixedly mounted on the mounting shaft 204 along the axial direction of the mounting shaft 204. Each mounting bracket 205 is provided with multiple workstations, which correspond one-to-one along the axial direction of the mounting shaft 204.

[0030] By setting a mounting shaft 204 that is fixedly connected to the rotating shaft 202, and setting at least two mounting brackets 205 on the mounting shaft 204, and setting corresponding workstations, a stable frame structure is formed, so that each calibration source 0 has at least two support points, ensuring stability during the test process.

[0031] Each station of the mounting bracket 205 is equipped with a quick-release structure for rapid installation and removal of the calibration source 0. The quick-release structure includes a V-shaped seat 206, an inverted V-shaped pressure block 207, a slip screw 208, and a locking nut 209 that cooperate with each other. The V-shaped seat 206 and the inverted V-shaped pressure block 207 surround and form a receiving cavity for accommodating the calibration source 0. The first ends of the V-shaped seat 206 and the inverted V-shaped pressure block 207 are hinged to each other, and the second end of the V-shaped seat 206 is hinged to the slip screw 208. The second end of the inverted V-shaped pressure block 207 has a through hole for the slip screw 208 to pass through. The locking nut 209 is used to cooperate with the slip screw 208 to lock the V-shaped seat 206 and the inverted V-shaped pressure block 207 with the calibration source 0 installed.

[0032] In use, first open the inverted V-shaped pressure block 207, place the calibration source 0 into the V-groove of the V-shaped seat 206, then close the inverted V-shaped pressure block 207, so that the upper part of the calibration source 0 is embedded in the inverted V-groove of the inverted V-shaped pressure block 207. Then, pass the upper end of the slip screw 208 through the through hole on the inverted V-shaped pressure block 207, put the locking nut 209 on the slip screw 208, and gradually tighten the locking nut 209 to complete the locking and fixing of the calibration source 0 by the V-shaped seat 206 and the inverted V-shaped pressure block 207.

[0033] The specific structure of the three-axis motion component is as follows: The Z-direction moving module 5 includes four sets of electric push rods 501 vertically arranged on the upper surface of the platform body 1; the moving ends of the four sets of electric push rods 501 are horizontally arranged on the first mounting platform 6, and the four sets of electric push rods 501 are respectively located at the four corners of the first mounting platform 6.

[0034] Movement in the Z direction requires ensuring the stability and levelness of the platform's lifting and lowering to avoid tilting that could cause deviation in the calibration optical path. In this embodiment, four sets of electric push rods 501 are symmetrically arranged at the four corners of the first mounting platform 6, synchronously driving the first mounting platform 6 to achieve smooth vertical lifting and lowering. The structure has high rigidity and the positioning accuracy can reach ±0.01mm.

[0035] The Y-direction moving module 4 includes two sets of linear guide rails 7 arranged parallel to each other on the first mounting platform 6, and a servo motor that drives the linear guide rails 7 to move; a second mounting platform 8 is provided on the sliders of the two sets of linear guide rails 7.

[0036] Movement in the Y direction needs to ensure linear accuracy and stability to avoid jitter or swaying affecting the calibration optical path. In this embodiment, two sets of parallel linear guides 7 are used and driven by servo motors. The slider drives the second mounting platform 8 to move along the Y-axis. The guides have strong guiding properties and low friction, ensuring accurate movement trajectory.

[0037] The X-direction moving module 3 includes two sets of linear guide rails 7 arranged parallel to each other on the second mounting platform 8, and a servo motor that drives the linear guide rails 7 to move; a third mounting platform 9 is provided on the sliders of the two sets of linear guide rails 7, and the rotating module 2 is mounted on the third mounting platform 9.

[0038] Movement in the X direction needs to be coordinated with the Y and Z directions to achieve precise three-dimensional positioning, and the structure needs to be compact to avoid interference. Another set of linear guides 7 and servo motors are installed on the second mounting platform 8 to drive the third mounting platform 9 to move along the X-axis, forming an orthogonal coordinate system with the Y and Z modules, achieving precise positioning of any point in space.

[0039] The electrical control system 10 includes a PLC controller and an operating interface for setting position and rotation angle parameters. By integrating motion control logic through the PLC controller and using a human-machine interface such as a touchscreen, users can intuitively set position and angle parameters. The system automatically executes multi-axis coordinated motion, simplifying the operation process.

[0040] The working process of this embodiment is as follows: 1. Preparation: Install the calibration source First, multiple radiation thermometers (as calibration sources) are installed at various stations of the rotary module 2. Each station is equipped with a quick-release mechanism. The operator simply opens the quick-release mechanism, places the calibration source into the receiving cavity formed by the V-shaped seat 206 and the inverted V-shaped pressure block 207, and then tightens the slip screw 208 and the locking nut 209 to quickly fix the calibration source 0. Since there are multiple stations, this embodiment uses six as an example, allowing six calibration sources to be installed simultaneously, thus achieving multi-station preparation.

[0041] 2. Initial positioning: Three-axis movement adjustment After calibration source 0 is installed, calibration parameters are set through the operation interface of electronic control system 10. First, the position in the XYZ directions is adjusted so that the calibration source is aligned with the target light source of the calibration equipment (such as an ultra-high temperature standard blackbody). Specific process: Z-direction adjustment: The electronic control system 10 controls the four sets of electric push rods 501 of the Z-direction moving module 5 to move synchronously, driving the first mounting platform 6 to rise and fall, so as to achieve precise positioning of the calibration source in the vertical direction with an accuracy of ±0.01mm.

[0042] Y-direction adjustment: The electronic control system 10 controls the servo motor of the Y-direction moving module 4 to drive two sets of linear guide rails 7, which in turn drive the second mounting platform 8 to move along the Y-axis to adjust the front and rear positions of the calibration source with an accuracy of ±0.01mm.

[0043] X-direction adjustment: The electronic control system 10 controls the servo motor of the X-direction moving module 3 to drive the other two sets of linear guides 7, which in turn drive the third mounting platform 9 to move along the X-axis to adjust the left and right position of the calibration source with an accuracy of ±0.01mm.

[0044] All movements are precisely controlled by a PLC controller, and operators can monitor position feedback in real time through the operating interface to ensure that the calibration source and the target light source are concentrically aligned.

[0045] 3. Rotation angle setting After the XYZ positions are confirmed, the rotation angle of the rotary module 2 is set via the electronic control system 10. The rotary module 2 is driven by a servo motor, and the rotation angle is controlled by encoder feedback, with an accuracy of ±0.02°. The operation interface allows input of rotation angle parameters, such as rotating the calibration source of the first station to align with the calibration light source. The rotary module 2 supports free switching between forward and reverse rotation.

[0046] 4. Calibration execution and workstation switching After parameter settings are completed, the calibration process is initiated. The calibration source at the first station begins calibration, such as collecting temperature data. After calibration, the electrical control system 10 automatically controls the rotating module to rotate a certain angle, such as 60°. Due to the uniform circumferential arrangement of the stations, the calibration source 0 at the next station is switched to the calibration position. The rotation process is smooth and accurate, without the need to readjust the XYZ positions.

[0047] Repeat this process until all six calibration sources at all stations have been calibrated.

[0048] 5. Cycle Completion and Subsequent Processing After a calibration cycle (six calibration sources) is completed, the operator can quickly disassemble the calibrated radiation thermometers using the quick-release mechanism and install a new source to be calibrated, preparing for the next cycle. The entire platform enables efficient and continuous calibration operations and is suitable for batch calibration scenarios.

[0049] This embodiment has the following advantages compared to existing calibration platforms: High efficiency: The multi-station rotary design and quick-release structure reduce clamping and changeover time, making it several times more efficient than a single-station calibration platform.

[0050] High precision: Three-axis precision movement (±0.01mm) and rotational positioning (±0.02°) ensure the alignment accuracy of the calibration source and improve the reliability of calibration data.

[0051] Automation: The electrical control system integrates a PLC and an operating interface, which simplifies the operation process and reduces errors caused by manual intervention.

[0052] This embodiment systematically solves the problems of low efficiency, poor accuracy, and cumbersome operation of traditional calibration platforms through the design of multi-station rotation, three-axis precision movement, quick-release structure, and integrated electronic control. It is suitable for radiation thermometer calibration and can also be extended to precision alignment applications in fields such as optics and 3C electronic communications.

[0053] Any adaptive changes made according to actual needs are within the protection scope of this utility model.

Therefore, the embodiments should be considered exemplary and non-limiting in all respects, and the scope of this utility model is defined by the appended claims rather than the foregoing description.
