Description

Technical Field

[0001] This utility model relates to the field of detection and provides a device for observing color change and degradation. Background Technology

[0002] The discoloration and degradation of traditional liquid products seriously affect product performance and quality, and this problem occurs frequently during transportation and storage. In existing technologies, testers often observe the products visually under natural light. This method is susceptible to variations in weather conditions, the observation environment, and the observer's skills, making it difficult to guarantee consistency in the observation environment and consequently compromising the accuracy of the measurement results.

[0003] The current common solution is to use a darkroom with preset light source and brightness for observation. This method achieves partial uniformity of the observation environment by controlling the intensity of the light source, but it still has limitations in practical use: samples with different discoloration and degradation colors may be affected by the color difference between samples even when observed under the same light source, resulting in inaccurate observation results; in addition, observing multiple samples at once will seriously affect experimental efficiency; in order to simulate the effects of different environmental conditions on the samples, it is necessary to frequently change the sample position, which may increase the risk of sample contamination and reduce the reliability of test results.

[0004] Therefore, there is an urgent need for a technology that can accurately and efficiently detect discoloration and degradation of liquid samples to ensure the consistency and accuracy of test results, reduce interference from external factors, and improve experimental efficiency.

[0028] The embodiments of this utility model will be described in further detail below with reference to the accompanying drawings and examples. The following examples are for illustrative purposes only and should not be construed as limiting the scope of this utility model.

[0029] like Figures 1 to 2 As shown, this utility model embodiment provides a discoloration and degradation detection device, comprising:

[0030] The chamber 100 has a temperature control element 102 installed on its top.

[0031] The shadowless lamp panel 104 is located at the bottom of the housing 100;

[0032] The platform 106 is positioned above the shadowless lamp panel 104. The platform 106 has a placement position 108 for placing the sample to be tested, and a baffle 110 is formed between two adjacent placement positions 108.

[0033] Image acquisition device 112 is set on stage 106 to acquire image information of the sample to be tested.

[0034] The color change and degradation detection device provided in this embodiment of the invention aims to achieve accurate detection of the degree of color change and degradation of samples through a series of precisely designed components.

[0035] The chamber 100 serves as the main structure of the entire testing device. It is made of robust and corrosion-resistant materials to ensure its stability and durability during use. A temperature control element 102 is installed on the top of the chamber 100 to regulate the temperature environment inside the chamber 100, simulating the discoloration and deterioration of the sample under different temperature conditions.

[0036] The shadowless lamp panel 104 is located at the bottom of the chamber 100, providing uniform and high-intensity illumination to ensure that every detail of the sample surface is clearly illuminated.

[0037] It should be noted that in this embodiment of the invention, the enclosure 100 is a closed and windowless structure, designed to make the shadowless lamp panel 104 the sole light source in the entire environment. With the help of the light-absorbing materials inside the enclosure 100, it provides a stable and accurate observation environment, reducing potential errors during the experiment and ensuring the accuracy and consistency of the observation results.

[0038] The stage 106, positioned above the shadowless lamp panel 104, is a key component for placing the samples to be tested. Multiple placement positions 108 for placing the samples are formed on the stage 106. Each placement position 108 is carefully designed to ensure that the samples can be placed stably and flat. Baffles 110 are formed between adjacent placement positions 108. These baffles 110 not only separate the samples but also prevent them from interfering with each other during the testing process.

[0039] The image acquisition unit 112 is positioned above or to the side of the stage 106 to acquire image information of the sample to be tested. The image acquisition unit 112 uses a high-resolution camera, capable of capturing minute changes on the sample surface. Simultaneously, the image acquisition unit 112 also has image processing capabilities, enabling preprocessing and analysis of the acquired images to more accurately determine the degree of discoloration and degradation of the sample.

[0040] The discoloration and degradation detection device provided in this embodiment of the present invention utilizes a shadowless lamp panel 104 to provide uniform illumination and an image acquisition unit 112 to capture high-resolution images, clearly displaying every detail of the sample surface and thus more accurately determining the degree of discoloration and degradation. The design of multiple placement positions 108 allows for the simultaneous detection of multiple samples, significantly improving detection efficiency. Furthermore, the addition of a temperature control unit 102 enables sample detection under different temperature conditions, further enriching the detection data. The entire detection device is simple and straightforward in design, and easy to operate. Additionally, the connections between components are robust and reliable, facilitating maintenance and replacement. The discoloration and degradation detection device provided in this embodiment of the present invention has significant advantages in terms of detection accuracy, efficiency, and ease of operation.

[0041] According to one embodiment of the present invention, the placement position 108 is arranged in a ring around the circumference of the shelf 106.

[0042] In this embodiment of the invention, the design of the placement position 108 has been further optimized. Specifically, the placement position 108 is arranged in a ring around the circumference of the shelf 106.

[0043] The circular arrangement leaves the central area of ​​the stage 106 empty, which not only provides a wider field of view for the image acquisition unit 112, ensuring that image information of the sample on each placement position 108 can be captured without blind spots, but also leaves room for other necessary detection equipment or operating space.

[0044] The circular arrangement ensures that each placement position 108 is equidistantly distributed on the stage 106, which helps to ensure that each sample is subjected to the same light and temperature conditions during the testing process, thereby improving the accuracy and consistency of the test results.

[0045] The circular arrangement also makes it easier for operators to place and retrieve samples on the stage 106. They can approach the stage 106 from any direction without worrying about being blocked by samples on other placement positions 108.

[0046] With improved space utilization, operators can place and retrieve samples more quickly, shortening the testing cycle and increasing efficiency. Each sample is subjected to the same lighting and temperature conditions, which helps eliminate testing errors caused by environmental factors and improves the accuracy of results. The circular layout makes operation more convenient, reducing operator workload and time, thus enhancing their user experience.

[0047] According to one embodiment of the present invention, a support 114 is provided on the shelf 106, and an image acquisition device 112 is disposed on the support 114.

[0048] In this embodiment of the utility model, a bracket 114 is added to the shelf 106, and the image acquisition device 112 is cleverly set on this bracket 114.

[0049] The introduction of the bracket 114 allows the image acquisition unit 112 to be adjusted to the optimal position as needed. Operators can flexibly adjust the height, angle, and position of the image acquisition unit 112 according to the size and shape of the sample to be tested and the testing requirements, to ensure that the clearest and most comprehensive image information can be captured.

[0050] The bracket 114 is designed with stability and load-bearing capacity in mind, thus ensuring that the image acquisition unit 112 remains stationary during the inspection process. This helps eliminate image blurring or distortion caused by shaking or displacement of the image acquisition unit 112, thereby improving the accuracy and reliability of the inspection results.

[0051] The design of the bracket 114 also makes the maintenance and upgrading of the image acquisition unit 112 more convenient. When the image acquisition unit 112 needs cleaning, repair or replacement, the operator can easily remove it from or install it on the bracket 114 without having to perform a large-scale disassembly or reassembly of the entire detection device.

[0052] By flexibly adjusting the position and angle of the image acquisition unit 112, operators can ensure the capture of the clearest image information, thereby improving the precision and accuracy of the detection results. A stable image acquisition environment helps reduce the problem of repeated detection caused by image blurring or distortion, thus shortening the detection cycle and improving detection efficiency. The easy-to-maintain and upgrade bracket 114 design reduces the maintenance cost of the image acquisition unit 112. Operators can perform daily maintenance and upkeep more conveniently, extending the service life of the image acquisition unit 112 and reducing replacement frequency and costs.

[0053] According to one embodiment of the present invention, the bracket 114 is rotatably mounted on the shelf 106.

[0054] In this embodiment of the invention, the bracket 114 is made of a lightweight yet robust material, such as aluminum alloy or high-strength plastic, to ensure that it can withstand the required load while being easy to operate and adjust. The shape and size of the bracket 114 are customized according to actual application needs to meet the support and storage requirements of different items.

[0055] The bracket 114 and the stage 106 are rotatably connected via a clever rotating connection mechanism. For example, the bracket 114 can rotate by a specific angle or an integer multiple of that angle under the control of a stepper motor. Each rotation of a specific angle allows the image acquisition unit 112 to rotate from the current sample center to the next sample center. When different numbers of samples are placed in the housing 100, the stepper motor can be used to adjust the rotation of the bracket 114 by an integer multiple of that specific angle, so that the image acquisition unit 112 on the bracket 114 can freely acquire image data of any sample. In addition, a locking mechanism can be provided to fix the position of the bracket 114 when needed.

[0056] The shelf 106 is also made of sturdy and durable materials and is designed with a mounting interface that matches the rotating connection mechanism of the bracket 114. The size and shape of the shelf 106 can be adjusted according to the actual application scenario to provide sufficient support area and stability.

[0057] Users can operate the bracket 114 electrically (such as by rotating a handle or pressing a button) to adjust its position and angle as needed. This design allows users to easily adjust the bracket 114 to its optimal usage state, improving space utilization and ease of operation.

[0058] Furthermore, users can adjust the height of the bracket 114 to match different sizes of test samples. During the adjustment process, the image clarity acquired by the image acquisition unit 112 can also be adjusted by changing parameters such as the focal length and aperture size. Moreover, for test samples of the same size, relevant control parameters (such as the focal length, aperture size, and height of the bracket 114 mentioned above) can be accumulated through previous experiments to further improve the image acquisition accuracy for test samples of the same size. This not only makes more efficient use of the space on the shelf 106, but also reduces the stacking and clutter of items, making the environment more tidy and orderly. Users can easily adjust the position and angle of the bracket 114 as needed without having to move or rearrange items. This design greatly improves the convenience and efficiency of operation, especially in scenarios where items need to be frequently retrieved and returned.

[0059] According to one embodiment of the present invention, a control component 116 is provided on the box 100, and a temperature measuring component is provided inside the box 100. The temperature measuring component, the temperature control component 102 and the control component 116 are electrically connected.

[0060] In this embodiment of the invention, the control component 116 is disposed on the exterior of the housing 100, typically in an easily accessible location. It can be a controller integrating a display screen and buttons, used to display the current temperature, set the target temperature, and receive other user commands. The control component 116 is connected to the temperature measuring element and the temperature controlling element 102 via internal circuitry to achieve data transmission and command issuance.

[0061] A temperature sensing element is installed inside the enclosure 100 to monitor the temperature inside the enclosure 100 in real time. It is typically a high-precision temperature sensor that accurately converts temperature data into an electrical signal and transmits it to the control unit 116 via an electrical connection. Based on the received temperature data, the control unit 116 determines whether the temperature inside the enclosure 100 needs to be adjusted.

[0062] Temperature controller 102 is an important component of the enclosure 100 system. It regulates the temperature inside the enclosure 100 according to the instructions of controller 116. Temperature controller 102 can be a heater, cooler, or a combination thereof, and achieves precise temperature control by adjusting power or operating mode. Temperature controller 102 communicates with controller 116 via electrical connection to ensure accurate execution of instructions.

[0063] Through the coordinated operation of the control component 116, the temperature measuring component, and the temperature control component 102, precise temperature control within the enclosure 100 is achieved. Users can set a target temperature according to actual needs, and the system automatically adjusts the operating state of the temperature control component 102 based on data provided by the temperature measuring component to maintain a constant temperature within the enclosure 100. Because the system can automatically adjust the operating state of the temperature control component 102 based on real-time temperature data, unnecessary energy consumption is avoided. Simultaneously, the high-precision temperature measuring component and the efficient temperature control component 102 ensure rapid temperature response and stable control, further improving the system's energy efficiency. The enclosure 100 system is designed with safety and reliability in mind. The robust and durable enclosure 100 material and its sealed design ensure the stability of the internal environment; meanwhile, the high precision and reliability of the control component 116 and the temperature measuring component guarantee stable system operation. Furthermore, the system also features overheat protection, short-circuit protection, and other safety measures to ensure safe use under abnormal conditions.

[0064] According to one embodiment of the present invention, the temperature control element 102 includes:

[0065] The power supply unit is located inside the enclosure 100;

[0066] The heating element is located inside the housing 100 and is electrically connected to the power supply unit. The control unit 116 is also electrically connected to the heating element.

[0067] In this embodiment of the invention, the power supply component is an important part of the temperature control component 102, responsible for providing stable electrical energy to the heating element. The power supply component is typically a DC power supply or an AC power adapter, with its output voltage and current customized according to the requirements of the heating element. The power supply component is housed within the housing 100 and connected to the control component 116 and the heating element via wires.

[0068] The heating element is the core component of the temperature control unit 102 used for temperature regulation. It is typically a resistance wire, heating film, or other form of heating element, capable of adjusting its operating state according to the instructions of the control unit 116, thereby changing the temperature inside the chamber 100. The heating element is disposed inside the chamber 100 and electrically connected to the power supply unit and the control unit 116. When the control unit 116 receives temperature data from the temperature sensor and determines that heating is required, it sends a command to the heating element to initiate its operation.

[0069] Through the coordinated operation of the control element 116, the temperature measuring element, and the temperature control element 102, precise temperature control within the chamber 100 is achieved. Users can set a target temperature according to their actual needs, and the system will automatically adjust the operating state of the heating element based on the data provided by the temperature measuring element to maintain a constant temperature within the chamber 100. Because the system can automatically adjust the operating state of the heating element based on real-time temperature data, unnecessary energy consumption is avoided. Simultaneously, the heating element is designed with high efficiency and stability in mind, enabling it to quickly respond to commands from the control element 116, thereby achieving rapid temperature adjustment and stable control.

[0070] According to one embodiment of the present invention, the temperature control element 102 has a temperature control range of -20 degrees Celsius to 80 degrees Celsius.

[0071] In this embodiment of the utility model, by designing the temperature control element 102 to adjust the temperature within a wide range of -20 degrees Celsius to 80 degrees Celsius, this system can be applied to a variety of application scenarios and meet the temperature control needs of different users.

[0072] Because the control unit 116 is characterized by high precision and rapid response, it can analyze temperature data in real time and make corresponding control decisions to ensure precise temperature control within the enclosure 100. This helps protect temperature-sensitive items from temperature fluctuations. The system can automatically adjust the operating status of the heating element (and possibly the cooling element) based on real-time temperature data, avoiding unnecessary energy consumption. Simultaneously, the heating element (and cooling element) is designed with high efficiency and stability in mind, enabling it to quickly respond to the commands of the control unit 116, thereby achieving rapid temperature adjustment and stable control.

[0073] According to one embodiment of the present invention, the brightness of the shadowless lamp panel 104 is less than or equal to 8000 nits, and the color temperature of the shadowless lamp panel 104 is greater than or equal to 5000 Kelvin.

[0074] In this embodiment of the invention, by limiting the brightness of the shadowless lamp panel 104 and setting a high color temperature, the system can provide users with a high-quality lighting experience. High brightness ensures sufficient illumination intensity, while a high color temperature helps improve visual clarity and color reproduction, enabling users to observe or photograph targets more accurately. Limiting the brightness of the shadowless lamp panel 104 to below 8000 nits helps reduce glare and light pollution, thereby protecting the user's eyesight. This is especially important for users who work under lighting for extended periods. A high-quality lighting experience helps improve user work efficiency. In environments requiring precise operations, such as operating rooms and precision machining workshops, high-clarity and color-reproducing light enables users to complete tasks more accurately. Through efficient heat dissipation design and safety protection functions, the system can ensure that the shadowless lamp panel 104 maintains a stable temperature during operation and prevents abnormal situations from occurring, thereby extending its service life.

[0075] According to one embodiment of the present invention, the inner wall of the box 100, the shelf 106 and the baffle 110 are all covered with light-absorbing material.

[0076] In this embodiment of the invention, the presence of the light-absorbing material effectively controls the light inside the box 100, improving the visibility and recognizability of the items inside. This helps users observe the state and characteristics of the items more accurately. The light-absorbing material absorbs most of the external light, reducing the impact of light on the internal environment of the box 100. This helps maintain a dim environment inside the box 100 and reduces interference from external light on the items inside. The light-absorbing material typically has a smooth surface and uniform color, enhancing the overall aesthetics of the box 100. Simultaneously, by reducing light reflection and scattering, the interior of the box 100 appears neater and more organized. The light-absorbing material typically has good wear resistance and corrosion resistance, extending the service life of the box 100. Furthermore, by reducing light exposure and damage to the box 100 material, it also helps maintain the integrity and stability of the box 100 material.

[0077] According to one embodiment of the present invention, the box 100 is an aluminum box 100.

[0078] In this embodiment of the invention, the aluminum case 100, with its lightweight and high-strength characteristics, makes it more convenient and less strenuous to carry and transport. Simultaneously, its high strength ensures that the case 100 maintains its integrity and stability when subjected to external impacts. The aluminum alloy material has excellent corrosion resistance, maintaining the integrity and stability of the case 100 in harsh environments such as humidity and acid / alkali conditions. This helps extend the service life of the case 100 and reduce maintenance costs. Aluminum alloy material is easy to process and customize, allowing for the production of case 100s of different shapes and sizes according to actual needs. This helps meet the needs of different application scenarios, improving the practicality and flexibility of the case 100. After surface treatments such as anodizing and spraying, the aluminum case 100 has an aesthetically pleasing appearance and a wear-resistant surface. This helps improve the overall quality and user experience of the case 100.
