Description

Technical Field

[0001] This utility model belongs to the field of infrared detection equipment technology, and specifically relates to an automatic scanning and data recording device for an infrared emissivity tester. Background Technology

[0002] The core purpose of an infrared emissivity tester is to accurately measure the emissivity of a material surface in a specific infrared band to ensure that the material meets usage requirements. The existing operating procedure for infrared emissivity testers involves the operator placing the material to be tested on the test table, then manually moving the material to measure and record the emissivity at multiple points on the material.

[0003] However, manually moving materials presents the following problems:

[0004] 1. Low detection efficiency: The sample position needs to be manually adjusted, resulting in low testing efficiency (single multi-point measurement takes more than 30 minutes).

[0005] 2. Scattered data records: Emissivity data is not linked to location coordinates, making it difficult to analyze spatial distribution characteristics.

[0006] 3. Poor repeatability: Manual positioning error leads to a deviation of >5% in multiple measurements at the same location.

[0007] Therefore, an automatic scanning and data recording device for infrared emissivity testing is needed. Utility Model Content

[0028] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. 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 of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0029] Next, refer to Figures 1 to 4 The working principle of this embodiment will be described in detail so that those skilled in the art can better understand this utility model:

[0030] An automatic scanning and data recording device for an infrared emissivity tester includes a worktable 1, a support rod 2, an infrared emissivity testing lens 3, an infrared emissivity testing main control unit 4, a computer main control unit, and a moving platform. One end of the support rod 2 is vertically mounted on the worktable 1, and the infrared emissivity testing lens 3 is mounted on the other end of the support rod 2. The infrared emissivity testing lens 3 is electrically connected to the infrared emissivity testing main control unit 4, which is also electrically connected to the computer main control unit. Users can query and control the infrared emissivity testing main control unit 4 via the computer. Users can preset scanning modes (grid, spiral, custom path) through the computer main control unit, thereby meeting the requirements of samples of arbitrary shapes and testing requirements, improving practicality.

[0031] The moving platform includes a base plate 5, an X-axis linear slide 6, a Y-axis linear slide 7, and a sample fixing stage 8. The base plate 5 is mounted on the worktable 1. The X-axis linear slide 6 is mounted on top of the base plate 5. The Y-axis linear slide 7 is mounted on the slide plate of the X-axis linear slide 6, and the X-axis and Y-axis linear slides 6 are perpendicular to each other. The sample fixing stage is mounted on the slide plate of the Y-axis linear slide 7. The X-axis linear slide 6 can drive the Y-axis linear slide 7 to move along the axis of the lead screw, and the Y-axis linear slide 7 can drive the sample fixing stage 8 to move along the axis of the lead screw, thereby moving the sample to any position on the horizontal plane, facilitating the detection of the sample at any position. The aforementioned linear slide, also called a linear module, can use a motor to drive the lead screw and slide plate for high-precision positioning. Compared to manual sample movement, this reduces movement errors and improves movement efficiency.

[0032] Displacement detection units are installed on both the X-axis linear slide 6 and the Y-axis linear slide 7 to measure the distance the slide moves. These displacement detection units are electrically connected to the infrared emissivity testing main control unit 4. The infrared emissivity testing main control unit 4 contains a memory.

[0033] The displacement detection unit here is a motor encoder (rotary encoder), installed on the output shaft of the drive motor (stepper or servo). It measures the motor's rotation angle and number of revolutions to calculate the displacement distance of the slide plate. Then, the displacement information of the X-axis and Y-axis is sent to the infrared emissivity test main control unit 4 for storage. The infrared emissivity test main control unit 4 saves the time information and emissivity value corresponding to each coordinate one by one for easy viewing by users.

[0034] In another embodiment, the displacement detection unit can also be a linear displacement sensor. The sensor reading head is directly mounted on the slide plate of the slide table and moves along the scale fixed on the slide table base to directly read the linear displacement.

[0035] The sample fixing stage 8 includes a placement plate 81 and a magnetic chuck 82. The placement plate 81 is mounted on the slide plate of the Y-axis linear slide 7, and the magnetic chuck 82 is mounted on top of the placement plate 81. The magnetic chuck 82 is made of magnetic material and can magnetically fix some metal samples that can be magnetically attracted, making it convenient to use and improving experimental efficiency.

[0036] The top of the placement plate 81 has a mounting groove 811, and the magnetic chuck 82 is installed in the mounting groove 811. The magnetic chuck 82 is flush with the top of the placement plate 81, which can increase the stability of the sample placed on the magnetic chuck 82. The magnetic chuck 82 and the placement plate 81 are fixedly connected by magnetic attraction. The placement plate 81 is made of a metal that can be magnetically attracted.

[0037] Furthermore, the placement plate 81 contains a cavity 812, which is connected to an air compressor via a pipe 83. The magnetic chuck 82 has a through hole 821, through which the cavity 812 communicates with the outside. The air compressor here is a miniature air compressor, which continuously draws air from the cavity 812, creating a negative pressure within the cavity to fix the sample on the magnetic chuck 82. This method is used to fix samples that cannot be magnetically attracted. The air compressor needs to be placed away from the testing platform to avoid its vibration affecting the infrared emissivity meter.

[0038] The magnetic chuck 82 has multiple through holes 821, which are evenly distributed across it. By designing the through holes 821 as multiple small-diameter holes evenly distributed on the magnetic chuck 82, it ensures that regardless of the sample's size and shape, at least one through hole 821 will be completely blocked by the sample, affecting air intake and creating negative pressure for fixation. This improves the practicality of this application, allowing for the fixation of any sample. Each through hole 821 is equipped with a filter screen 84 to prevent impurities and foreign objects from entering the cavity 812 and to prevent blockage of the cavity 812 and the pipe 83.

[0039] Multiple positioning rods 9 are vertically mounted on the bottom of the base plate 5. Positioning holes 10 corresponding to the positioning rods 9 are provided on the worktable 1. Threaded holes 11 are horizontally provided on the side wall of the worktable 1, communicating with the positioning holes 10. Corresponding threaded holes 11 are also provided on the positioning rods 9. The positioning rods 9 and positioning holes 10 are connected and fixed by bolts 12. When the mobile platform is not needed, the user can remove the bolts 12 from the threaded holes 11, then lift the base plate 5 upwards to separate the positioning holes 10 from the positioning rods 9, thus completing the disassembly of the mobile platform. The installation method is the reverse of the above steps.

[0040] Taking a 5×12cm tinplate sample as an example, place it on the fixed sample stage, where the magnetic chuck 82 firmly adheres to the sample plate. Preheat the infrared emissivity test main control unit 4 to the required temperature (test 8-14um - temperature 250℃, test 3-5um - temperature 300℃) for one hour. Replace the test lens. After preheating, debug and calibrate the infrared emissivity test main control unit 4, determine the path of the computer main control unit, and slide the X-axis linear slide 6 and Y-axis linear slide 7 to the designated position according to the predetermined path for testing. The computer main control unit data system records and saves the data.

[0041] In summary, this application provides an automatic scanning and data recording device for an infrared emissivity tester. This device is an auxiliary device suitable for multi-dimensional automatic scanning and synchronous recording of infrared emissivity data on the surface of metal and fabric layers. It is a convenient, simple, fast, and accurate auxiliary device that processes and records data, thereby improving overall work efficiency.
