[0002] Fabric thickness is typically measured using a fabric thickness tester in the prior art. The fabric is laid flat for testing, and the testing principle is to use a micrometer for measurement.

Therefore, they should not be construed as limitations on the present invention. Furthermore, the terms "first," "second," and "third," etc., are used solely to distinguish descriptions and should not be construed as indicating or implying relative importance.

[0025] like Figures 1-9 As shown, an intelligent fabric thickness detection device includes a support roller 1 and a detection roller 2. The fabric 4 to be detected is stretched toward the support roller 1 and passes between the support roller 1 and the detection roller 2. A photo detection module 3 is provided on the front side of the support roller 1. The photo detection module includes an image sensor. The detection roller 2 is used to coat the upper surface of the fabric 4 to be detected with a colored material, and the coloring of the fabric 4 to be detected is photographed and compared by the photo detection module 3 to determine whether the thickness of the fabric 4 to be detected is uniform. A plurality of detection needles 5 and a distance sensor are arranged inside the detection roller 2. The detection needles 5 can extend to the recessed position of the fabric 4 to be detected, and the distance sensor is used to detect the extension distance of the detection needles 5.

[0026] The photo detection module 3 is used to capture the coloration of the surface of the fabric to be tested 4. An image of the qualified fabric can be extracted in advance as a comparison image, and the coloration image of the fabric to be tested can be compared with the comparison image. During testing, the fabric to be tested 4 is pressed downward at both ends and passed between the support roller 1 and the detection roller 2. The movement of the fabric drives the detection roller 2 to rotate.

[0027] The image sensor can use industrial-grade CMOS sensors (such as Sony IMX series) or linear array CCD sensors (Teledyne DALSA Piranha4), supporting micron-level texture recognition and capturing 0.01mm 2 It can adjust the coloring difference and integrate dynamic exposure compensation function to adapt to fabrics with different reflective properties.

[0028] At the same time, multispectral imaging technology (with optional near-infrared band) combined with pre-stored digital twin models of qualified fabrics generates a real-time thickness difference heat map. A certain deviation threshold is set, and an alarm is triggered when the local color deviation exceeds the deviation threshold.

[0029] The non-ferrous material department uses solid powder materials or viscous liquid materials. In order to improve the color rendering effect, different non-ferrous materials can be selected according to the color of the fabric to be tested. The non-ferrous materials can be selected from one or more of titanium dioxide, carbon black, paint, color paste, fluorescent agent, etc.

[0030] The distance sensor can be a laser displacement sensor (Keyence IL-100) or a capacitive sensor (Micro-Epsilon capaNCDT series), which has nanometer-level resolution, fast response, and resistance to dust interference.

[0031] like Figure 1 As shown, support frames 6 are provided on both sides of the support roller 1, and a connecting shaft 7 is provided in the axial direction of the detection roller 2, and the connecting shaft 7 can slide along the height direction of the support frame 6; The bottom of the detection roller 2 contacts the fabric to be detected 4, and the fabric to be detected 4 drives the support roller 1 to rotate when it moves. A paint distribution plate 8 is provided on the upper part of the detection roller 2, and the paint distribution plate 8 is used to apply colored material to the upper surface of the fabric to be detected 4.

[0032] The axis of the inspection roller can be equipped with a miniature six-axis inertial sensor (BMI270) to monitor the roller's vibration spectrum in real time. If abnormal vibration is detected, the camera detection module 3 automatically triggers additional capture. An infrared temperature sensor can also be appropriately configured to locate potential pilling areas through fabric friction thermal imaging.

[0033] The length of the coating distribution plate 8 is not less than the length of the detection roller 2, and the colored material is evenly coated on the circumferential direction of the detection roller 2 through the coating distribution plate 8, and the length of the detection roller 2 is not less than the width of the fabric 4 to be detected.

[0034] like Figure 1 and Figure 7 As shown, a vertical adjustment slot 9 is provided inside the support frame 6, an adjustment telescopic rod 10 is provided at the bottom of the adjustment slot 9, and a support spring 11, a pressure sensor 12 and a connecting slider 13 are provided in sequence from bottom to top in the adjustment slot 9, and the connecting shaft 7 of the detection roller 2 is rotatably connected to the connecting slider 13.

[0035] The connecting shaft 7 is connected to the connecting slider 13 via the connecting shaft 7, and the connecting slider 13 can float up and down along the adjustment slot 9. The connecting slider 13 is supported by the support spring 11. The pressure sensor 12 is used to detect the downward pressure of the connecting slider 13. This pressure is derived from the downward gravity of the detection roller 2. When the pressure value detected by the pressure sensor 12 decreases, indicating that the detection roller 2 and the support roller 1 are pressed tightly together, the adjustment telescopic rod 10 is extended, and the detection roller 2 and the support roller 1 are separated.

[0036] like Figure 8 and Figure 9 As shown, a plurality of detection holes are evenly opened on the circumferential surface of the detection roller 2, and a connecting pipe 14 is provided inside the detection hole; A through hole 17 for accommodating the movement of the detection needle 5 is provided in the axial direction of the connecting tube 14 . A distance sensor 15 is provided at one end of the connecting tube 14 away from the detection roller 2 . The distance sensor 15 is used to detect the outward extension length of the detection needle 5 .

[0037] The detection needle 5 can extend outward through the detection hole. When there is a depression in the fabric 4 to be detected, the detection needle 5 at the corresponding position will extend outward to a certain length. The extended length of the detection needle 5 is detected by the distance sensor 15 to know the depth of the depression in the fabric 4 to be detected.

[0038] like Figure 9 As shown, a limit end block is provided at the end of the detection needle 5 opposite to the distance sensor 15, and an accommodating channel for accommodating the limit end block is provided in the axial direction of the connecting tube 14, and a plurality of air holes 16 are provided between the accommodating channel and the outer side of the detection roller 2.

[0039] The detection section of the distance sensor 15 is arranged toward the limit end block, and the limit end block can move inside the accommodating channel.

[0040] like Figure 1 As shown, a plurality of ventilation holes 18 are evenly arranged on the circumferential surface of the support roller 1 , and a ventilation fan 19 is connected to the axial direction of the support roller 1 .

[0041] The ventilation fan 19 is used to blow air toward the axial direction of the support roller 1. When the vent 18 and the air hole 16 are arranged opposite to each other, the air blown into the air hole 16 through the vent 18 to balance the internal and external air pressures of the connecting pipe 14, so that the detection needle 5 can slide out smoothly.

[0042] like Figure 1 As shown, a tensioning roller group 20 is provided on the front side and the rear side of the support roller 1. The axis of the tensioning roller group 20 is lower than the axis of the support roller 1. The fabric 4 to be tested is tightened by the tensioning roller group 20.

[0043] like Figure 1 As shown, the axis of the detection roller 2 and the axis of the support roller 1 are located in the same vertical plane. After the fabric 4 to be detected is tightened, the photo detection module 3 is set toward the fabric 4 to be detected on the front side of the detection roller 2.

[0044] This application also includes a controller and a display. The photo detection module 3 takes a photo of the fabric to be tested and transmits the image information to the display. The staff can observe the coloration of the fabric to be tested 4 through the display and can also compare the coloration of the fabric to be tested 4 through the controller, processor, etc. The specific controller model and processor model, system operating parameters, etc. are set according to the usage habits of those skilled in the art and the actual fabric testing needs, and will not be detailed here.

[0045] Directions: When the device is used, the fabric 4 to be tested is passed between the support roller 1 and the detection roller 2, and the fabric 4 to be tested is tightened by the tensioning roller group 20, thereby driving the fabric to move; The pressure sensor 12 is used to detect the degree of compression between the detection roller 2 and the support roller 1, so that the detection roller 2 is in light contact with the fabric 4 to be detected; As the fabric moves, the detection roller 2 rotates with the fabric, and the colored material is evenly coated on the fabric to be detected 4 through the detection roller 2, and the concave condition of the fabric is detected by the detection needle 5 at the same time; The interior of the support roller 1 is ventilated by a ventilation fan, and the ventilation is blown toward the support roller 1 through the air holes 16. When the air holes 18 are arranged opposite to the air holes 16, air enters the interior of the connecting tube 14 through the air holes 16. Under the push of air pressure, the detection needle 5 can move outward. When there is a dent in the fabric 4 to be detected, the detection needle 5 extends outward accordingly. The extension length of the detection needle 5 is detected by the distance sensor 15. According to the type of fabric to be detected, different distance detection thresholds are set by the controller. When the extension length of the detection needle 5 is greater than the set detection threshold, the fabric to be detected is an unqualified product. Correspondingly, multiple detection needles 5 can also be set inside the connecting tube 14 to improve the detection range and detection accuracy. After the fabric contacts the detection roller 2, the surface of the fabric will be coated with colored material. When the fabric 4 to be detected has knots, missing weaves, etc., the surface of the fabric 4 to be detected will be in contact with the colored material to varying degrees after the fabric contacts the detection roller 2, causing the surface of the fabric 4 to appear to be lacking color or heavy color. The coloring of the surface of the fabric 4 to be inspected is photographed by the photographing detection module 3. The staff can observe the coloring of the fabric 4 to be inspected to know whether the thickness of the fabric is uniform. The staff can also compare the photographed photo and the comparison picture through the controller. Correspondingly, a detection threshold can be set. When the proportion of the color-deficient or heavy-colored area to the length of the photograph exceeds the set detection threshold, it indicates that the fabric to be inspected is unqualified.
