Description

Technical Field

[0001] This utility model belongs to the field of textile production quality inspection technology, and in particular relates to an online color difference detection device for fabrics. Background Technology

[0002] Color difference is a key indicator of product quality in fabric production. Color difference can stem from various factors, including different dye batches, fluctuations in dyeing process parameters, and uneven fabric texture. Therefore, rapid and accurate color difference detection on the production line is crucial for controlling product quality and reducing defect rates.

[0003] Currently, common color difference detection methods are mainly divided into two types: manual visual inspection and instrumental inspection. Manual visual inspection is greatly affected by ambient light, the subjective experience of the inspector, and fatigue; it is difficult to standardize inspection criteria, resulting in insufficient stability and reliability, and low efficiency. While existing instrumental inspection equipment has improved detection accuracy to some extent, it still has many limitations: First, many testing devices are offline sampling tests, which cannot achieve continuous online testing of the entire width of the fabric, resulting in the risk of missed detections and failing to fully reflect the quality of the entire fabric.

[0004] Secondly, some online inspection devices have fixed probe positions or limited adjustment ranges, making it difficult to cover the entire width of the fabric, especially for wide fabrics, resulting in blind spots. Furthermore, fixed probes cannot quickly and accurately switch between fabric inspection and standard color chart calibration modes. Complex mechanical structures or even manual operation are usually required to move and turn the probe, which not only reduces inspection efficiency but also introduces the risk of human error, making it difficult to meet the demands of high-speed, automated production in the modern textile industry.

[0005] Secondly, ambient light interference is another key factor affecting the accuracy of color difference detection. Existing equipment often lacks effective light-shielding measures, meaning that changes in natural light or workshop lighting can directly affect the readings of the detection sensor, resulting in inaccurate detection results.

[0006] Therefore, there is an urgent need in this field for an automated color difference detection device that can integrate automatic scanning, precise positioning, online calibration, and resistance to ambient light interference, in order to solve the problems of incomplete detection, low efficiency, and accuracy being greatly affected by human and environmental factors in the existing technology. Utility Model Content

[0007] This application provides an online color difference detection device for fabrics to solve the technical problems of existing color difference detection devices, such as incomplete detection coverage, cumbersome operation, and inability to quickly switch between detection and calibration modes.

[0008] To achieve the above objectives, the following technical solution is provided: an online color difference detection device for fabrics, comprising a housing, wherein a detection chamber and a transmission chamber are respectively arranged inside the housing, and the upper end of the housing is fastened by a cover; a sliding component is arranged inside the detection chamber, and a color difference detection module is arranged on the sliding component; a rotating component is arranged in the transmission chamber, and one end of the sliding component is fixedly connected to the rotating component; an interactive component is also arranged on the side wall of the housing; The color difference detection module is used to detect the color difference of the fabric. The sliding component drives the color difference detection module to move horizontally, and the rotating component drives the sliding component and the color difference detection module to rotate synchronously.

[0009] Furthermore, the sliding assembly includes a suspension rod, the bottom of which has a groove along its length, a slider is slidably disposed in the groove, and the color difference detection module is disposed on the slider; The slide is also equipped with a lead screw and a sliding motor. The lead screw is threadedly connected to the slider, and one end of the lead screw is rotatably connected to the end wall of the slide through a bearing, while the other end is poweredly connected to the output shaft of the sliding motor.

[0010] Furthermore, the rotating assembly includes an internal gear disk rotatably mounted on the side wall of the transmission cavity, a fixed frame fixedly connected to the side of the internal gear disk facing the detection cavity, and one end of the suspension rod fixedly connected to the middle of the fixed frame.

[0011] Furthermore, a rotating motor is installed inside the transmission cavity, and a gear is fixedly mounted on the output shaft of the rotating motor. The gear meshes with the internal gear ring of the internal gear disk.

[0012] Furthermore, at least one positioning groove is provided circumferentially on the side wall of the fixed frame, and an elastic positioning pin is correspondingly provided on the side wall of the transmission cavity. When the fixed frame rotates to a specific angle, the end of the elastic positioning pin is embedded in the positioning groove.

[0013] Furthermore, the testing equipment also includes a light-shielding box located below the housing, with a material conveying channel formed inside the light-shielding box. The material conveying channel runs through the bottom of the light-shielding box and is connected to the testing chamber.

[0014] Furthermore, a standard color card is also fixedly embedded on the side wall of the detection cavity, and the arrangement direction of the standard color card is parallel to the movement direction of the sliding component.

[0015] Furthermore, an illumination lamp for providing a standard light source is also provided on the inner wall of the detection chamber.

[0016] Furthermore, the interactive components include a display screen fixedly mounted on the outer wall of the housing, and the display screen is signal-connected to the color difference detection module.

[0017] Furthermore, the interactive components also include a control switch, which is electrically connected to the sliding component, the color difference detection module, and the rotation component.

[0018] This invention achieves full coverage of the detection range and rapid switching of working modes through a structure in which a sliding component and a rotating component work together. Specifically, the lead screw transmission mechanism in the sliding component drives the detection module to move precisely along the width of the fabric, achieving blind-spot-free scanning; the rotating component, through gear-internal gear disk transmission, enables the entire detection unit to quickly switch between fabric detection and standard color card calibration positions. This not only solves the problem of limited detection range of fixed probes but also achieves seamless switching between detection and calibration modes, significantly improving detection efficiency and automation. Furthermore, the modular design facilitates maintenance and upgrades.

[0019] Furthermore, this application achieves a stable testing environment and precise calibration through the design of a light-shielding box, standard color card, and standard lighting system. The light-shielding box forms a closed material conveying channel, effectively isolating ambient light interference; the built-in standard color card and D65 standard light source provide a stable color comparison benchmark. This ensures consistent lighting in the testing environment, eliminates measurement errors caused by changes in ambient light, and enables the equipment to perform automatic online calibration at any time. This solves the problems of traditional equipment being greatly affected by environmental interference and inconvenient calibration, significantly improving the reliability and accuracy of the testing data.

[0020] Secondly, this application achieves intelligent operation and real-time monitoring through the interactive components and automated control system. The interactive components integrate a display screen and control switches, displaying real-time detection data, color difference distribution maps, and equipment status, and providing a one-button operation interface. Combined with the PLC control system, it achieves automated operation of functions such as sliding scanning, mode switching, and positioning locking. This solves the problems of complex operation and insufficient data visualization in traditional equipment, enabling operators to quickly grasp the equipment's operating status and adjust parameters in a timely manner, meeting the needs of modern textile production for intelligent and human-machine interaction.

[0023] The technical solutions of the embodiments of this application will be clearly described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this application. All other embodiments obtained by those skilled in the art based on the embodiments of this application are within the scope of protection of this application.

[0024] In the description of this application, it should be noted that the terminology used herein is for the purpose of describing particular embodiments only and is not intended to limit the exemplary embodiments according to this application. For ease of description, the dimensions of the various parts shown in the drawings are not drawn to actual scale. Techniques, methods, and devices known to those skilled in the art may not be discussed in detail, but where appropriate, such techniques, methods, and devices should be considered part of the specification. In all examples shown and discussed herein, any specific values ​​should be interpreted as merely exemplary and not as limitations. Therefore, other examples of exemplary embodiments may have different values. It should be noted that similar reference numerals and letters in the following drawings denote similar items; therefore, once an item is defined in one drawing, it need not be further discussed in subsequent drawings.

[0025] In the field of textile production quality inspection technology, color difference detection of fabrics is a crucial step in ensuring product quality. Existing technologies for manual visual inspection and instrument-based inspection have several limitations: manual inspection is greatly affected by ambient light and subjective human factors, and inspection standards are inconsistent; while instrument-based inspection equipment is often offline sampling inspection, unable to achieve continuous online inspection across the entire fabric width, and the fixed position or limited adjustment range of the inspection probe leads to blind spots, and it is difficult to quickly switch between the inspected fabric and the calibration standard color chart. Furthermore, ambient light interference severely affects inspection accuracy. The root cause of these problems lies in the lack of integrated automatic scanning, positioning, and calibration mechanisms in existing equipment, as well as effective light-shielding measures.

[0026] To address the aforementioned problems, this utility model provides an online color difference detection device for fabrics. Through innovative design of sliding components, rotating components, light-blocking structures, and an interactive system, it achieves comprehensive, rapid, and accurate detection of color differences in fabrics. The technical solution and effects of this utility model will be described in detail below with reference to the accompanying drawings and multiple embodiments. Example 1

[0027] refer to Figures 1 to 6 The online color difference detection device for fabrics of this utility model includes a housing 10, inside which are respectively arranged a detection chamber 11 and a transmission chamber 12, and the upper end of the housing 10 is fastened by a cover 13. A sliding assembly 30 is arranged inside the detection chamber 11, and a color difference detection module 40 is arranged on the sliding assembly 30. A rotating assembly 50 is arranged in the transmission chamber 12, and one end of the sliding assembly 30 is fixedly connected to the rotating assembly 50. An interactive assembly 60 is also arranged on the side wall of the housing 10. The color difference detection module 40 is used to detect the color difference of the fabric. The sliding assembly 30 drives the color difference detection module 40 to move horizontally, and the rotating assembly 50 drives the sliding assembly 30 and the color difference detection module 40 to rotate synchronously.

[0028] In this technical solution: the equipment adopts a modular design. The detection chamber 11 is used to accommodate the fabric and detection components, and the transmission chamber 12 is used to install the drive mechanism. The sliding component 30 and the rotating component 50 work together to enable the color difference detection module 40 to move horizontally to scan the fabric width and rotate to switch between detection and calibration modes. The interactive component 60 provides a human-machine interface for easy operation and monitoring. The snap-fit ​​design of the cover 13 ensures the airtightness of the detection chamber 11 and prevents interference from the external environment.

[0029] By integrating sliding and rotating functions, the problem of incomplete detection coverage and cumbersome mode switching in existing equipment is solved. The sliding component 30 allows the color difference detection module 40 to move along the width of the fabric, achieving full-width scanning without blind spots; the rotating component 50 enables the detection module to quickly switch between fabric inspection and standard color card calibration, improving detection efficiency and accuracy. The overall structure is compact, suitable for online continuous inspection, and meets the needs of high-speed automated production. In addition, the modular design facilitates maintenance and upgrades, reducing equipment operation and maintenance costs.

[0030] The color difference detection module 40 preferably uses a spectral colorimeter. By measuring the spectral reflectance curve of an object across the entire visible light spectrum (e.g., 380-780nm), the color coordinates under various standard light sources (e.g., D65, D50, A light sources) are calculated. It should be noted that the selection of the spectral colorimeter in this embodiment is not specifically limited in this application; a Hikvision lens with model number MVL-HF0628M-6MPE is preferred. Example 2

[0031] like Figure 2 , Figure 3 and Figure 4 As shown, the sliding assembly 30 includes a suspension rod 31. A groove 32 is formed at the bottom of the suspension rod 31 along its length. A slider 33 is slidably disposed in the groove 32, and the color difference detection module 40 is disposed on the slider 33. A lead screw 34 and a sliding motor 35 are also disposed in the groove 32. The lead screw 34 is threadedly connected to the slider 33, and one end of the lead screw 34 is rotatably connected to the end wall of the groove 32 through a bearing, while the other end is poweredly connected to the output shaft of the sliding motor 35.

[0032] In this technical solution: the suspension rod 31 is horizontally fixed in the detection chamber 11, and its length is designed according to the fabric width to ensure coverage of the entire width. When the sliding motor 35 starts, it drives the lead screw 34 to rotate. Since the lead screw 34 is threadedly connected to the slider 33, the slider 33 moves horizontally along the slide groove 32, driving the color difference detection module 40 to move synchronously. The lead screw 34 adopts a high-precision ball screw, and the bearing support ensures smooth operation. The sliding motor 35 is a stepper motor or servo motor, which can precisely control the movement speed and position.

[0033] The sliding assembly in this embodiment solves the problem of limited detection range of the fixed probe. Through lead screw drive, the color difference detection module 40 can be precisely moved to any position on the fabric, achieving continuous scanning across the entire width and avoiding the risk of missed detections in sampling inspections. The lead screw drive has high rigidity and low backlash, ensuring the accuracy and repeatability of the movement and reducing the impact of positional errors on the detection results.

[0034] Meanwhile, the automated control of the sliding motor 35 eliminates the tediousness of manual adjustment and improves inspection efficiency, making it especially suitable for production lines producing wide-width fabrics. Furthermore, the chute 32 structure restricts the movement trajectory of the slider 33, preventing wobbling and deviation, further enhancing the stability of the equipment's inspection capabilities. Example 3

[0035] like Figure 3 , Figure 5 and Figure 6 As shown, the rotating assembly 50 includes an internal gear disk 51 rotatably mounted on the side wall of the transmission cavity 12. A fixing frame 52 is fixedly connected to the side of the internal gear disk 51 facing the detection cavity 11, and one end of the suspension rod 31 is fixedly connected to the middle of the fixing frame 52. A rotating motor 54 is also provided inside the transmission cavity 12. A gear 55 is fixedly mounted on the output shaft of the rotating motor 54, and the gear 55 meshes with the internal gear ring of the internal gear disk 51.

[0036] In this technical solution: the internal gear disk 51 is mounted on the side wall of the transmission cavity 12 via bearings and can rotate freely. The fixed frame 52 is fixedly connected to the internal gear disk 51, and the suspension rod 31 is fixed on the fixed frame 52, thus the suspension rod 31, the fixed frame 52, and the internal gear disk 51 form an integral rotating structure. When the rotary motor 54 starts, it drives the gear 55 to rotate. The gear 55 meshes with the internal gear ring of the internal gear disk 51, driving the internal gear disk 51 and the fixed frame 52 to rotate, thereby causing the suspension rod 31 and the color difference detection module 40 to rotate synchronously. The rotary motor 54 also adopts a stepper motor or a servo motor, which can control the rotation angle.

[0037] The rotating component in this embodiment solves the problem of inconvenient switching between detection modes. Through gear-internal gear drive, the color difference detection module 40 can quickly and accurately rotate to a predetermined angle, for example, switching from the fabric detection position (vertically downwards) to the standard color card calibration position (horizontally towards the side wall). This design avoids complex manual adjustments or additional mechanical mechanisms, achieving fully automatic mode switching and reducing human error and time consumption. The gear drive has high transmission efficiency and stability, ensuring the accuracy of the rotation angle. Simultaneously, the integration of the rotating component 50 and the sliding component 30 enables the device to achieve multi-degree-of-freedom movement within a limited space, improving the device's functionality and adaptability.

[0038] like Figure 5 As shown, at least one positioning groove 53 is provided on the side wall of the fixed frame 52 along the circumferential direction, and an elastic positioning pin 56 is correspondingly provided on the side wall of the transmission cavity 12. When the fixed frame 52 rotates to a specific angle, the end of the elastic positioning pin 56 is embedded in the positioning groove 53.

[0039] Positioning slots 53 are set according to key locations, such as one for fabric inspection and one for standard color card calibration. The elastic positioning pin 56 includes a pin body and a spring; the spring ensures the pin body always tends to move towards the fixing frame 52. When the fixing frame 52 rotates to a specific angle, the positioning slot 53 aligns with the elastic positioning pin 56, and the pin body, under the spring force, embeds into the positioning slot 53, achieving mechanical locking. The rotating motor 54, when driven, must overcome the spring force to disengage the positioning pin.

[0040] The positioning mechanism in this embodiment solves the problem of unstable rotational position. During detection or calibration, vibration or external force may cause the color difference detection module 40 to shift position, affecting detection accuracy. Through the cooperation of the elastic positioning pin 56 and the positioning groove 53, rigid locking is achieved at key positions, ensuring the stability of the color difference detection module 40 and preventing accidental movement. This mechanism is simple, reliable, low-cost, and does not affect the smoothness of rotational movement. Without a positioning mechanism, the rotating component may rotate excessively due to inertia or external interference, causing the detection point to deviate; this design eliminates this risk through mechanical interlocking, improving the reliability and repeatability of the equipment.

[0041] like Figure 1 , Figure 2 As shown, in a preferred embodiment of this application, the testing device further includes a light-shielding box 20 disposed below the housing 10. A material conveying channel 21 is formed inside the light-shielding box 20. The material conveying channel 21 passes through the bottom of the light-shielding box 20 and is connected to the transmission cavity 12.

[0042] The light-shielding box 20 is made of opaque material (such as black ABS plastic or metal), and its internal surface is treated with a matte finish to reduce light reflection. The size of the feeding channel 21 matches the width of the fabric, and the fabric passes through the channel into the detection chamber 11. The connection between the light-shielding box 20 and the housing 10 is sealed to prevent light leakage. The detection chamber 11 itself is secured by the cover 13, further isolating ambient light.

[0043] The light-shielding box in this embodiment solves the problem of ambient light interference in detection accuracy. In color difference detection, changes in ambient light directly affect the readings of the color sensor, leading to measurement errors. With the light-shielding box 20, the fabric is in a dark environment before entering the detection chamber 11, eliminating the influence of external light sources. The design of the feeding channel 21 allows the fabric to pass through continuously, enabling online detection while maintaining the light-shielding effect.

[0044] When traditional equipment is used for testing in a brightly lit workshop, changes in natural light or lighting can cause fluctuations in test results. The light-shielding box 20, however, creates a stable lighting environment, ensuring consistent testing conditions and improving the reliability and comparability of the data. At the same time, the light-shielding structure reduces the sensor's sensitivity to stray light, lowering the calibration frequency.

[0045] As a preferred embodiment of this application, such as Figure 2 and Figure 3 As shown, a standard color card 41 is also fixedly embedded on the side wall of the detection cavity 11, and the arrangement direction of the standard color card 41 is parallel to the movement direction of the sliding component 30.

[0046] An illumination lamp 42 for providing a standard light source is also provided on the inner end wall of the detection chamber 11. The illumination lamp 42 is preferably arranged around the inner wall of the detection chamber 11 so that the light can be clearly illuminating the fabric to be tested and the standard color card 41, ensuring that the color difference detection module 40 can clearly complete the comparison and correction when aligned with the standard color card 41.

[0047] During actual installation, the installation position of the lighting lamp 42 should be avoided from being too high, so as not to cause the light source to shine on the suspension rod 31 and cover the fabric detection surface with shadows, thereby affecting the detection accuracy of the color difference detection module 40.

[0048] The standard color chart 41 contains multiple standard color samples and is mounted on the side wall of the detection chamber 11, its length matching the range of motion of the suspension rod 31. The illumination lamp 42 uses a standard light source (such as D65 simulated sunlight) and is mounted on the top or side wall of the detection chamber 11 to provide uniform illumination. The color difference detection module 40 can be rotated via the rotating component 50 to face the standard color chart 41 and moved along the color chart via the sliding component 30 for multi-point calibration.

[0049] The use of a standard color chart and illumination lamp solves the problems of inconvenient testing and calibration and inconsistent light sources. By integrating the standard color chart 41, the equipment can automatically calibrate periodically, eliminating errors caused by sensor drift or aging. The standard light source of the illumination lamp 42 ensures uniform illumination conditions during testing and calibration, avoiding color display differences under different light sources. The additional design of the standard color chart 41 allows the equipment to quickly switch to calibration mode during testing, achieving continuous accuracy control. Simultaneously, the sliding component 30 enables the color difference detection module 40 to scan along the color chart for multi-point calibration, improving the comprehensiveness and accuracy of calibration. The uniform illumination of the illumination lamp 42 reduces shadows and reflections, further optimizing the testing environment. Example 4

[0050] like Figure 1 As shown, the interactive component 60 includes a display screen 61 fixedly mounted on the outer wall of the housing 10, and the display screen 61 is signal-connected to the color difference detection module 40. The interactive component 60 also includes a control switch 62, which is electrically connected to the sliding component 30, the color difference detection module 40, and the rotation component 50.

[0051] In this technical solution: the display screen 61 is a touch screen or LCD screen, used to display detection data in real time, such as color difference value, position information, alarm status, etc. The control switch 62 includes buttons and knobs, used to start / stop the equipment, switch modes, adjust parameters, etc. All components are integrated through a control system (such as a PLC or microcontroller) to achieve automated operation. The display screen 61 can also be connected to an external network for data storage and remote monitoring.

[0052] The interactive components address the issues of operational complexity and insufficient data visualization. Through display screen 61, operators can intuitively view inspection results, quickly identify color difference anomalies, and adjust production processes promptly. Control switch 62 centralizes equipment control functions, simplifying the operation process and reducing training costs. This integrated interactive interface enhances user experience and efficiency, while real-time data recording and analysis facilitates quality traceability and process optimization, meeting the needs of modern smart factories.

[0053] Based on the above embodiments, the workflow of the device is as follows: The fabric enters the detection chamber 11 from the feeding channel 21 of the light-shielding box 20. The sliding component 30 drives the color difference detection module 40 to move along the width of the fabric for scanning and detection. The detection data is displayed in real time on the display screen 61 of the interactive component 60. When calibration is required, the rotating component 50 drives the color difference detection module 40 to rotate to the position of the standard color card 41, and the sliding component 30 moves the detection module along the color card for calibration. After calibration, the rotating component 50 rotates it back to the detection position. Throughout the process, the lighting lamp 42 provides a standard light source, and the light-shielding box 20 ensures stable ambient light.

[0054] The equipment operates automatically through program control. For example, in detection mode, the sliding motor 35 and the color difference detection module 40 work continuously, while the rotating motor 54 starts when switching modes; the positioning mechanism ensures position locking; and the interactive components allow for manual intervention or parameter setting.

[0055] This application's integrated workflow solves the problems of discontinuous detection, cumbersome operation, and low accuracy in existing technologies. Through the coordinated use of sliding and rotation, fully automated detection and calibration are achieved, covering the full width of the fabric without blind spots. A light-shielding environment and standard light source eliminate external interference, ensuring consistent detection. Interactive components provide efficient human-machine interaction. The overall equipment has a reasonable structure, high reliability, and is suitable for high-speed textile production lines, significantly improving the level of fabric quality control.

[0056] The above description is merely a specific embodiment of this utility model, but the protection scope of this utility model is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in this utility model should be included within the protection scope of this utility model. Therefore, the protection scope of this utility model should be determined by the protection scope of the claims.
