Description

Technical Field

[0001] This utility model belongs to the technical field of environmental testing equipment. Specifically, this utility model relates to an ultraviolet aging test machine device. Background Technology

[0002] In recent years, with the rapid development of modern society and technological progress, touchscreens, as a simple, responsive, and space-saving human-computer interaction method, have been widely used in various fields such as tablet computers, mobile phones, automotive displays, and healthcare. Ultraviolet (UV) aging test chambers are testing equipment that simulates the conditions of ultraviolet (UV) radiation, temperature, and humidity in the natural environment to accelerate material aging. UV aging experiments simulate the damage caused by different environmental conditions such as UV bands in sunlight, visible light, ultraviolet rays, rain, and condensation. The test material is placed in a cycle of alternating light and moisture at a certain temperature to accelerate the aging process and help testers assess the weather resistance of materials in a short time. However, existing UV aging test devices do not irradiate the test samples evenly, resulting in inaccurate test results.

[0003] Chinese Patent (Publication No.: 209432673U) discloses an ultraviolet aging test apparatus, including a test apparatus body, a placement partition, a test apparatus top cover, and an observation window. A hinge is fixedly installed on one side of the test apparatus body via screws. The test apparatus top cover is movably installed on the test apparatus body via the hinge. An ultraviolet searchlight is fixedly installed on the bottom inner wall of the test apparatus top cover. Both the test apparatus body and the inner wall of the test apparatus top cover are fitted with ultraviolet isolation layers. A support plate is fixedly installed on the inner wall of the test apparatus body via screws, and a test material placement plate is movably placed on top of the support plate. When the ultraviolet irradiation received by the test sample in this ultraviolet aging test apparatus is uneven, the test results become inaccurate. Utility Model Content

[0004] This utility model is designed to solve the above-mentioned problems and aims to provide a UV aging test machine that can irradiate test samples more uniformly and provide more accurate test results. To achieve the above objective, the technical solution adopted by this utility model is as follows: a UV aging test machine, including a chamber, wherein a light source structure and a sample rack structure are provided inside the chamber.

[0005] The sample rack structure includes a rotating sample rack and a tray sample plate. The rotating sample rack is located at the bottom of the box, and the tray sample plate is located inside the box.

[0006] The rotating sample holder includes a rotating motor, which is located at the bottom of the housing, and the rotating motor shaft is connected to a rotating disk.

[0007] The light source structure includes a first UV xenon lamp and a second UV xenon lamp. The first UV xenon lamp is located at the top of the chamber, with its luminous surface facing the sample tray. The second UV xenon lamp is located on both sides of the chamber.

[0008] A temperature and humidity sensor is installed at the bottom of the rotating disk, and a control panel is installed outside the box. The control panel, the rotating motor, the first UV xenon lamp, the second UV xenon lamp, and the temperature and humidity sensor are connected to a PLC controller.

[0009] A UV xenon lamp reflector is provided at the bottom of the rotating disk.

[0010] An isolation plate is provided at the opening of the box, the isolation plate is connected to the rotating shaft of the box, and an observation window is provided on the isolation plate.

[0012] The technical effects of this invention are as follows: the first and second UV xenon lamps irradiate the sample with ultraviolet light from different directions, and the rotating sample holder allows the sample to receive radiation from all directions and multiple angles. The UV xenon lamp reflector further improves the utilization rate of ultraviolet light.

Detailed Implementation

[0017] The specific embodiments of the present invention will be further described in detail below with reference to the accompanying drawings, in order to help those skilled in the art to have a more complete, accurate and in-depth understanding of the inventive concept and technical solution of the present invention, and to facilitate its implementation.

[0018] like Figures 1-2 As shown, an ultraviolet aging test chamber includes a housing 1, within which a light source structure 2 and a sample holder structure 3 are installed. The housing 1 is square in shape and serves as the basic framework of the entire ultraviolet aging test chamber. The housing 1 provides installation space and support for the internal light source structure 2 and sample holder structure 3, while also protecting the internal structure and isolating the test environment from the external environment, ensuring that the test is conducted in a relatively stable and enclosed environment, avoiding interference from external factors. The light source structure 2 provides ultraviolet irradiation, simulating ultraviolet radiation from different directions in the natural environment, allowing the sample to be subjected to ultraviolet aging from all directions, thus more realistically simulating the aging process of the sample in actual use. The sample holder structure 3 is used to place the sample to be tested, providing a stable platform for the sample.

[0019] The sample holder structure 3 includes a rotating sample holder 31 and a tray sample plate 301. The rotating sample holder 31 is located at the bottom of the housing 1, and the tray sample plate 301 is located inside the housing 1. During use, when the sample is placed on the tray sample plate 301, uneven light exposure may occur, affecting experimental results. By setting a rotating sample holder 31 at the bottom of the housing 1, the sample can receive light more evenly when placed on the rotating sample holder 31, resulting in more accurate experimental results. Simultaneously, the samples on the rotating sample holder 31 and the samples on the tray sample plate 301 can form a set for comparison, further enhancing the accuracy of the experimental results.

[0020] The rotating sample holder 31 includes a rotating motor, which is located at the bottom of the housing 1. The rotating motor shaft is connected to a rotating disk 311. The rotating motor provides rotational power to the rotating disk 311. After the test begins, the rotating motor starts, driving the rotating disk 311 to rotate. The sample placed on the rotating disk 311 rotates accordingly, allowing the sample to undergo ultraviolet aging tests at different angles and positions, making the test results more accurate.

[0021] The light source structure 2 includes a first UV xenon lamp 201 and a second UV xenon lamp 202. The first UV xenon lamp 201 is located at the top inside the chamber 1, with its emitting surface facing the sample tray 301. The second UV xenon lamps 202 are located on both sides inside the chamber 1. By placing the first UV xenon lamp 201 at the top inside the chamber 1 and the second UV xenon lamps 202 on both sides inside the chamber 1, the first UV xenon lamp 201, with its emitting surface facing the sample tray 301, is mainly used to irradiate the sample on the sample tray 301 with ultraviolet light in a vertical direction. It can also irradiate the sample on the rotating sample holder 31. The second UV xenon lamp 202 can irradiate the sample from the side. The first UV xenon lamp 201 and the second UV xenon lamp 202 work together to simulate ultraviolet radiation from different directions in the natural environment, allowing the sample to be exposed to ultraviolet aging from all directions, thus more realistically simulating the aging process of the sample in actual use.

[0022] A temperature and humidity sensor 4 is installed at the bottom of the rotating disk 311. A control panel 5 is installed outside the chamber 1. The control panel 5, rotating motor, first UV xenon lamp 201, second UV xenon lamp 202, and temperature and humidity sensor 4 are connected to a PLC controller. The temperature and humidity sensor 4 is used to monitor the temperature and humidity environment inside the chamber 1 in real time, and transmits the collected temperature and humidity data to the PLC controller. The PLC controller adjusts the test environment according to the preset temperature and humidity range to ensure that the test is carried out under suitable temperature and humidity conditions. The control panel 5 is the interface for operators to interact with the UV aging test machine. Operators can set test parameters, such as test time, light intensity, and temperature and humidity range, through the control panel 5 and transmit these parameters to the PLC controller. The PLC controller receives test parameter setting instructions from the control panel 5 and temperature and humidity data from the temperature and humidity sensor 4. According to the preset program and logic, it controls the operation of the rotating motor, first UV xenon lamp 201, second UV xenon lamp 202, and cooling fan 7 to achieve automated control of the test process, ensuring that the test is carried out according to the set parameters and procedures, and guaranteeing the accuracy and consistency of the test results.

[0023] A UV xenon lamp reflector 6 is installed at the bottom of the rotating disk 311. The UV xenon lamp reflector 6 is located at the bottom of the rotating disk 311, and its main function is to reflect part of the ultraviolet rays emitted by the first UV xenon lamp 201 and the second UV xenon lamp 202, so that more ultraviolet rays can irradiate the sample, improve the utilization rate of ultraviolet rays, enhance the irradiation intensity and uniformity of the sample, and thus more effectively simulate the ultraviolet aging of the sample in the actual environment, thereby improving the test results.

[0024] An isolation plate 101 is installed at the opening of the chamber 1. The isolation plate 101 is connected to the rotating shaft of the chamber 1, and an observation window 102 is provided on the isolation plate 101. The isolation plate 101 is located at the opening of the chamber 1, mainly to isolate the internal test environment of the chamber 1 from the external environment, maintain the sealing of the interior of the chamber 1 during the test, and prevent external light, dust, moisture and other factors from entering the interior of the chamber 1 and interfering with the test results. At the same time, the observation window 102 on the isolation plate 101 allows the operator to observe the test status of the sample inside the chamber 1 without opening the isolation plate 101.

[0025] A cooling fan 7 is installed at the bottom of the chamber 1. The cooling fan 7 is located at the bottom of the chamber 1 and is mainly used to dissipate heat from the inside of the chamber 1. During the test, the light source structure 2 will generate heat, causing the temperature inside the chamber 1 to rise. The cooling fan 7 uses forced air convection to expel the heat from the inside of the chamber 1, thereby reducing the temperature inside the chamber 1. Together with the temperature and humidity sensor 4 and the PLC controller, the inside of the chamber 1 is kept within a suitable temperature range, ensuring that the test is carried out under stable temperature conditions and avoiding the impact of excessive temperature on the aging test results of the samples and the normal operation of the equipment.

[0026] The role and effect of the embodiments

[0027] The first UV xenon lamp 201 and the second UV xenon lamp 202 irradiate the sample with ultraviolet light from different directions. The rotating sample holder 31 allows the sample to receive radiation from all directions and multiple angles. The UV xenon lamp reflector 6 further improves the utilization rate of ultraviolet light. At the same time, the temperature and humidity sensor 4 and the cooling fan 7 regulate the temperature and humidity of the test environment, simulating ultraviolet aging conditions close to the natural environment. This makes the aging effect on the sample in the test more similar to actual use. The overall design is simple, easy to operate, and has a low mechanical failure rate. It can effectively detect the changes in the weather resistance of the sample material in the aging chamber.

Obviously, the specific implementation of the present invention is not limited to the above-described manner. Any non-substantial improvements made using the inventive concept and technical solution of the present invention; or the direct application of the inventive concept and technical solution to other situations without modification, are all within the protection scope of the present invention.
