Description

Technical Field

[0001] This application relates to the field of testing machines, and more particularly to a detector and an automatic vertical core suction height tester. Background Technology

[0002] In the current technological field, detectors, as an important detection tool, are widely used in various industrial and scientific research scenarios to observe and record specific properties or states of objects. Among them, thermal imaging cameras, as the core component of detectors, exhibit unique advantages in applications such as detecting the water absorption properties of fabrics due to their ability to measure the temperature distribution on the surface of objects non-contactly. However, traditional detector designs often face some inherent limitations and challenges.

[0003] Specifically, conventional detectors are typically designed for fixed use in a specific location, with the position and shooting angle of their thermal imaging cameras relatively fixed. In practical applications, to improve the clarity of images captured by the thermal imaging camera, inspectors often try to bring the fabric to be inspected close to the camera lens in hopes of obtaining a finer and clearer image. However, this approach has encountered numerous difficulties in practice.

[0004] When fabric is close to a thermal imaging camera, while the magnification effect of the lens helps improve image detail, the camera's field of view shrinks accordingly. This means that if the fabric is large or has a complex shape, the thermal imaging camera cannot capture the entire fabric's water absorption in a single shot. To obtain complete inspection information, inspectors must employ a strategy of multiple shots, moving the fabric to capture images from different locations.

[0005] However, this approach has significant problems. Because fabrics possess a certain degree of shape stability and internal tension, moving the fabric is likely to alter its original shape and water absorption distribution, thus adversely affecting the accuracy and reliability of the test results. Especially in applications requiring high testing precision, such errors introduced by fabric movement are often unacceptable. Utility Model Content

[0006] In view of this, it is necessary to provide a new type of detector and an automatic vertical wicking height tester to solve the problem that the moving fabric may change its original shape and water absorption distribution, thereby adversely affecting the accuracy and reliability of the test results.

[0007] Embodiments of this application provide a detector for detecting the water absorption capacity of a fabric, comprising:

[0008] Thermal imaging camera, used to capture thermal images of fabrics;

[0009] A first driving mechanism, wherein the thermal imaging camera is mounted on the first driving mechanism, the first driving mechanism is connected to the thermal imaging camera in a transmission manner, and the first driving mechanism drives the thermal imaging camera to move along a first direction;

[0010] The second drive mechanism is provided on the first drive mechanism, and the second drive mechanism is connected to the first drive mechanism in a transmission manner. The second drive mechanism drives the first drive mechanism to move along a second direction, which is perpendicular to the first direction.

[0011] The first drive mechanism and the second drive mechanism respectively drive the thermal imaging camera to move in the first direction and the second direction to capture thermal imaging images of different positions of the fabric.

[0013] A first slide rail, wherein the thermal imaging camera is slidably connected to the first slide rail, and the length direction of the first slide rail is parallel to the first direction;

[0014] A first motor is located at one end of the first slide rail. The first motor is connected to the thermal imaging camera in a transmission manner. The first motor drives the thermal imaging camera to slide along the length direction of the first slide rail.

[0015] In at least one embodiment of this application, the second drive mechanism includes:

[0016] The second slide rail has its length direction parallel to the second direction, and the first slide rail is slidably connected to the second slide rail;

[0017] The second motor is located at one end of the second slide rail and is connected to the first slide rail in a transmission manner. The second motor drives the first slide rail to slide along the length direction of the second slide rail.

[0018] In at least one embodiment of this application, the second drive mechanism has a second motor, which is located at one end of the second slide rail.

[0019] In at least one embodiment of this application, the detector further includes a light source device disposed on the first driving mechanism.

[0024] A transport mechanism is slidably connected to the testing frame. The transport mechanism drives the sample clamp to move, and the sample clamp drives the fabric to move.

[0025] A test tank is located on the movement path of the fabric.

[0026] The detector and automatic vertical wicking height tester provided above, by designing a combination of a first drive mechanism and a second drive mechanism in the detector, allow the thermal imaging camera to move along two vertical directions (the first direction and the second direction), thereby enabling flexible adjustment of the shooting position and angle. This ensures that a wider range of images can still be captured when shooting close to the fabric, and a complete image of the water absorption can be obtained without moving the fabric multiple times. Furthermore, integrating this detector into an automatic vertical wicking height tester further improves the stability of the fabric's position during the testing process.

[0035] Embodiments of this application provide a detector for detecting the water absorption capacity of a fabric, comprising:

[0036] Thermal imaging camera, used to capture thermal images of fabrics;

[0037] A first driving mechanism, wherein the thermal imaging camera is mounted on the first driving mechanism, the first driving mechanism is connected to the thermal imaging camera in a transmission manner, and the first driving mechanism drives the thermal imaging camera to move along a first direction;

[0038] The second drive mechanism is provided on the first drive mechanism, and the second drive mechanism is connected to the first drive mechanism in a transmission manner.

A complete image of water absorption can be obtained without moving the fabric multiple times. Integrating this detector into an automatic vertical wicking height tester further improves the stability of the fabric's position during the detection process.

[0046] The following detailed description of some embodiments of this application is provided in conjunction with the accompanying drawings. Unless otherwise specified, the following embodiments and features can be combined with each other.

[0047] Please see Figures 1-4 An embodiment of this application provides a detector 100 for detecting the water absorption capacity of a fabric, comprising:

[0048] Thermal imaging camera 1 is used to capture thermal images of fabrics.

[0049] The first driving mechanism 2 is provided, and the thermal imaging camera 1 is mounted on the first driving mechanism 2. The first driving mechanism 2 is connected to the thermal imaging camera 1 in a transmission manner, and the first driving mechanism 2 drives the thermal imaging camera 1 to move along the first direction a.

[0050] The second drive mechanism 3 is mounted on the first drive mechanism 2. The second drive mechanism 3 is connected to the first drive mechanism 2 in a transmission manner. The second drive mechanism 3 drives the first drive mechanism 2 to move along the second direction b, which is perpendicular to the first direction a.

[0051] The first driving mechanism 2 and the second driving mechanism 3 respectively drive the thermal imaging camera 1 to move in the first direction a and the second direction b to capture thermal imaging images of different positions of the fabric.

[0052] Specifically, the thermal imaging camera 1 is an existing technology, and its working principle is based on infrared sensing technology. It utilizes an infrared sensor to receive and measure infrared radiation emitted from the surface of an object, reflecting the object's heat distribution. Subsequently, the thermal imaging camera 1 converts this infrared radiation into electrical signals, and through signal processing and image generation algorithms, transforms these electrical signals into visualized thermal images. These thermal images display the temperature distribution of the object's surface in different colors or brightness levels, allowing us to intuitively see the object's heat distribution. As the core component of the detector 100, the thermal imaging camera 1 can non-contactly measure the temperature distribution of an object's surface, offering a unique advantage for detecting the water absorption performance of fabrics. The surface temperature of the fabric changes after absorbing water, and the thermal imaging camera 1 can capture these subtle temperature differences, thus reflecting the fabric's water absorption state. The first drive mechanism 2 is connected to the thermal imaging camera 1 and is responsible for driving the thermal imaging camera 1 to move along a first direction a (e.g., the horizontal direction). Driven by the first drive mechanism 2, the thermal imaging camera 1 can move freely in the horizontal direction, thereby covering a wider detection area. This is particularly important for detecting large-area fabrics. The second drive mechanism 3 is connected to the first drive mechanism 2 and is responsible for driving the first drive mechanism 2 (and the thermal imaging camera 1 mounted thereon) to move along the second direction b (e.g., the vertical direction). The second direction b is perpendicular to the first direction a, forming a two-dimensional plane movement capability. Driven by the first drive mechanism 2, the thermal imaging camera 1 can move linearly, rotate, or otherwise along the first direction a to capture thermal images of the fabric at different positions in that direction. The second drive mechanism 3 allows the thermal imaging camera 1 to move in the second direction b, which is perpendicular to the first direction a or at a certain angle to other directions, to further capture thermal images of the fabric at different positions in that direction.

[0053] In a specific example, the first drive mechanism 2 includes:

[0054] The first slide rail 21 is slidably connected to the thermal imaging camera 1, and the length direction of the first slide rail 21 is parallel to the first direction a.

[0055] A first motor 22 is located at one end of the first slide rail 21. The first motor 22 is connected to the thermal imaging camera 1 in a transmission manner. The first motor 22 drives the thermal imaging camera 1 to slide along the length direction of the first slide rail 21.

[0056] Specifically, the first slide rail 21 is a long, narrow guide rail whose length direction is parallel to the first direction a (usually horizontal). The surface of the slide rail is typically precision-machined to ensure smoothness and accuracy during sliding. The first slide rail 21 provides a stable sliding path for the thermal imaging camera 1. The thermal imaging camera 1 is slidably connected to the slide rail via some form of connection (such as a slider, roller, etc.), ensuring smooth movement along the length direction of the slide rail under motor drive. The first motor 22 is typically a stepper motor, DC motor, or servo motor, depending on application requirements and cost considerations. The motor provides the driving force and is connected to the thermal imaging camera 1 via some transmission mechanism (such as a belt, chain, gear, etc.), driving the camera to slide along the length direction of the first slide rail 21. The motor is typically connected to a control system, which receives commands and controls the motor's start, stop, speed, and direction. By precisely controlling the motor's movement, precise positioning and movement of the thermal imaging camera 1 on the slide rail can be achieved.

[0057] In one specific example, the second drive mechanism 3 includes:

[0058] The second slide rail 31 has its length direction parallel to the second direction b, and the first slide rail 21 is slidably connected to the second slide rail 31.

[0059] The second motor 32 is located at one end of the second slide rail 31. The second motor 32 is connected to the first slide rail 21 in a transmission manner. The second motor 32 drives the first slide rail 21 to slide along the length direction of the second slide rail 31.

[0060] Specifically, the second slide rail 31 is also a long, narrow guide rail, but its length direction is parallel to the second direction b (usually a horizontal or vertical direction perpendicular to the first direction a). The design and structure of the second slide rail 31 are similar to the first slide rail 21, but its size and load-bearing capacity may differ depending on actual needs. The second slide rail 31 provides a stable sliding path for the first slide rail 21, allowing the first slide rail 21 (and the thermal imaging camera 1 mounted on it) to move smoothly along the second direction b under the drive of the second motor 32. This design enables flexible movement of the thermal imaging camera 1 in a two-dimensional plane. The second motor 32 can also be a stepper motor, DC motor, or servo motor, depending on application requirements and cost considerations. Similar to the first motor 22, the selection of the second motor 32 should meet the power and precision requirements for driving the first slide rail 21 (and its load). The second motor 32 is responsible for providing the driving force, connected to the first slide rail 21 through some transmission mechanism (such as a belt, chain, gear, etc.), driving the first slide rail 21 to slide along the length direction of the second slide rail 31. This design enables movement of the thermal imaging camera 1 in another direction within a two-dimensional plane. The second motor 32 is also connected to the control system, which is responsible for receiving commands and controlling the motor's start, stop, speed, and direction. By precisely controlling the movement of the second motor 32, the first slide rail 21 (and the thermal imaging camera 1 mounted on it) can be precisely positioned and moved on the second slide rail 31.

[0061] In one specific example, the second drive mechanism 3 has a second motor 32, which is located at one end of the second slide rail 31.

[0062] Specifically, the second motor 32 is the power source of the second drive mechanism 3. It converts electrical energy into mechanical energy to generate driving force, propelling the first slide rail 21 along the second slide rail 31. The second motor 32 may be one of the following types: DC motor, AC motor, stepper motor, servo motor, etc. Different types of motors have different performance characteristics, such as speed, torque, and control precision. The choice of motor type depends on specific application requirements and equipment design. The second slide rail 31 provides a smooth and precise movement path for the first slide rail 21. The second slide rail 31 may adopt a linear guide, V-shaped guide, ball bearing guide, or other structural forms. These structural forms have different coefficients of friction, precision, and load-bearing capacity. The choice of structure depends on factors such as the weight of the load, the moving speed, and the precision requirements. According to the description, "the second motor 32 is located at one end of the second slide rail 31." This means that the second motor 32 is installed at one end of the second slide rail 31. This layout allows the motor to directly drive the load on the slide rail for linear movement. The second motor 32 may be connected to the load or the first slide rail 21 on the slide rail via a coupling, pulley, gear, or other transmission device. These transmission devices are used to transmit the driving force of the motor and may provide functions such as deceleration and torque increase. The specific connection method used depends on factors such as the type of motor, the weight of the load, and the moving speed. When the second motor 32 starts, it generates driving force and transmits it to the first slide rail 21 through the transmission device. Under the action of the driving force, the first slide rail 21 moves linearly along the second slide rail 31. By controlling the speed and direction of the motor, the moving speed and position of the load can be precisely controlled.

[0063] In one specific example, the detector 100 further includes:

[0064] Light source device 4 is mounted on the first drive mechanism 2.

[0065] Specifically, the light source device 4 is typically a device capable of emitting light of a specific wavelength or spectral range. It may include one or more light-emitting diodes (LEDs), laser diodes, halogen lamps, xenon lamps, or other types of light sources. The selection of these light sources depends on the specific requirements of the detector 100, such as the characteristics of the target being detected, the required illumination intensity, spectral range, etc. The light source device 4 is mounted on the first drive mechanism 2. This means that the light source device 4 can move with the movement of the first drive mechanism 2, thereby providing a dynamic illumination effect. This configuration is particularly suitable for detection tasks that require scanning or tracking targets, as the light source can always remain near the target, ensuring optimal illumination conditions. The primary function of the light source device 4 is to provide illumination to light the target being detected or to excite it to emit fluorescence, phosphorescence, etc. This helps to enhance the sensitivity, accuracy, and reliability of the detector 100. For example, in thermal imaging detection, although the thermal imaging camera 1 itself does not rely on an external light source to detect heat distribution, the light source device 4 can be used to illuminate other objects in the scene for visual confirmation or to assist in detection. Because the light source device 4 is mounted on the first drive mechanism 2, it can move synchronously with the movement of the detection component (such as the thermal imaging camera 1). This synchronicity ensures that the light source always illuminates the target area, regardless of the target's movement. In some advanced inspection systems, the light source device 4 may also have the ability to dynamically adjust the illumination intensity, spectral range, or illumination angle. This can be adjusted in real time according to the needs of the inspection task to optimize the inspection results.

[0066] In one specific example, the detector 100 further includes:

[0067] Visible light camera 5, which is mounted on the first drive mechanism 2.

[0068] Specifically, the main function of the visible light camera 5 is to capture images of the target object within the visible spectrum. Unlike the thermal imaging camera 1, the visible light camera 5 relies on light reflected from the object's surface to form an image, making it more suitable for observing the object's shape, color, texture, and other appearance features. In detection tasks, the visible light camera 5 can serve as a powerful supplement to the thermal imaging camera 1. By simultaneously capturing thermal and visible light images, the detector 100 can gain a more comprehensive understanding of the target object's state. The visible light camera 5 is mounted on the first drive mechanism 2. This means that the visible light camera 5 can move along with the drive mechanism, thereby achieving dynamic tracking and imaging of the target object. The first drive mechanism 2 may be a motor-driven slide rail, a rotating platform, or other mechanical structure capable of controlling the camera's position. Since both the visible light camera 5 and the thermal imaging camera 1 (if also mounted on the same drive mechanism) are controlled by the first drive mechanism 2, they can move synchronously. This synchronicity ensures that both cameras can simultaneously capture images of the target object, thus providing more accurate detection results.

[0069] An embodiment of this application provides an automatic vertical wicking height tester 200, which is used to measure the water absorption capacity of fabrics. The automatic vertical wicking height tester 200 includes:

[0070] The detection frame 201, on which the second drive mechanism 3 of the detector 100 is disposed;

[0071] The sample clamp 202 is disposed on the detection frame 201, and the fabric is clamped on the sample clamp 202;

[0072] The transport mechanism 203 is slidably connected to the testing frame 201. The transport mechanism 203 drives the sample clamp 202 to move, and the sample clamp 202 drives the fabric to move.

[0073] Test tank 204 is located on the movement path of the fabric.

[0074] Specifically, an automatic vertical wicking height tester 200 is a device specifically designed to measure the water absorption capacity of fabrics. This tester, through a series of precisely designed mechanisms, automates the monitoring and height measurement of the fabric's water absorption process, providing an accurate and efficient means for evaluating fabric water absorption performance. The testing frame 201 is the supporting structure of the entire tester, used to install and fix other key components, such as the drive mechanism, sample clamp 202, and transport mechanism 203. It ensures the stability and accuracy of the tester. The testing frame 201 is likely made of robust and durable materials, possessing sufficient rigidity and stability to withstand various loads during operation. The sample clamp 202 is used to hold the fabric sample to be tested. It should be designed to be sufficiently secure to ensure that the fabric sample does not fall off or shift during testing. Simultaneously, the clamp design should also consider the fabric's characteristics and testing requirements to ensure the accuracy and reliability of the test. The transport mechanism is slidably connected to the testing frame 201, used to move the sample clamp 202 and the fabric sample on it. This sliding connection allows the transport mechanism 203 to move freely along a predetermined path on the testing frame 201, thereby achieving automated transport and positioning of the fabric sample. During the test, the transport mechanism 203 is responsible for moving the fabric sample from its initial position to above the test tank 204 and returning it to its original position or the next processing position after the test. The test tank 204 is located on the movement path of the fabric and is one of the key components of the tester. The tank contains an appropriate amount of test liquid (such as water) to simulate the water absorption environment of the fabric in actual use. When the fabric sample is moved above the tank by the transport mechanism 203, it is immersed in the liquid in the tank. Subsequently, under the action of gravity and capillary action, the liquid is absorbed upwards along the fibers of the fabric. By observing this water absorption process, the water absorption performance of the fabric can be evaluated. When the fabric absorbs water, the uneven absorption and distribution of moisture causes changes in the surface temperature of the fabric. The thermal imaging camera 1 can capture these temperature changes and convert them into visualized thermal images. By analyzing these thermal images, the water absorption rate and water absorption uniformity of the fabric can be evaluated.

[0075] Furthermore, during the fabric absorbency testing process, firstly, the fabric sample to be tested is clamped onto the sample holder 202, ensuring it is secure and does not fall off. Then, the test tank 204 is filled with an appropriate amount of test liquid. After the tester is started, the transport mechanism 203 begins operation, moving the sample holder 202 and the fabric sample along a predetermined path above the test tank 204. Once the fabric sample is immersed in the liquid in the tank, the absorbency process begins. At this time, the thermal imaging camera 1 begins to observe and record the temperature changes on the fabric surface. After the test, the transport mechanism 203 moves the fabric sample back to its original position or the next processing location. Simultaneously, the tester analyzes and processes the collected thermal image data to evaluate the fabric's absorbency performance.

[0076] The above description is merely an embodiment of this application. It should be noted that those skilled in the art can make improvements without departing from the inventive concept of this application, but these improvements all fall within the protection scope of this application.
