Description

Technical Field

[0001] This utility model relates to the field of fabric production technology, and more specifically, it relates to an automatic light source adjustment and telescopic device for automatic fabric detection. Background Technology

[0002] In the textile industry, real-time quality inspection of fabrics is necessary to promptly identify substandard fabrics and improve product quality. For example, industrial cameras can be used to inspect fabric seams, allowing workers to cut the fabric at the seams.

[0003] However, real-time fabric inspection often relies on fixed locations, fixed illuminance light boxes, or top lighting. Furthermore, because fabrics of different materials, colors, and textures require different lighting conditions during inspection, the light intensity needs to be adjusted in real-time to meet the lighting needs of different types of fabrics, enabling industrial cameras to achieve more accurate fabric identification. Therefore, the existing technology has the following problems that urgently need to be solved: (1) Uneven illumination: a single fixed light source is prone to overexposure or underexposure on some dark or reflective fabrics, resulting in unclear imaging and affecting the accuracy of visual leak detection algorithms; (2) Difficulty in matching color temperature: some colored fabrics require a color temperature closer to natural light to accurately distinguish subtle color differences; (3) Changes in the detection area: fabrics move at a constant speed on a fast conveyor belt, requiring different angles and distances of supplementary lighting for different parts, while traditional manual adjustment or fixed supports cannot respond in real time, leading to missed or false detections; (4) Difficult maintenance: fixed light boxes are large and require manual adjustment, resulting in high debugging costs; if not calibrated for a long time, the detection accuracy will significantly decrease.

[0029] The technical solution of this utility model will be further described in detail below through specific embodiments and in conjunction with the accompanying drawings: Embodiment 1: Referring to Figures 1 to 6 As shown, an automatic light source adjustment telescopic device for automatic fabric detection includes a base 1, on which a vertical moving device 2, a first telescopic device 3, a second telescopic device 4, and a universal adjustment component 5 are provided.

[0030] The vertical moving device 2 includes a vertical slide groove 21 fixed on the base 1 and arranged vertically, a vertical lead screw 22 disposed within the vertical slide groove 21, and a vertical motor 23 disposed at the top of the vertical slide groove 21 with its output end connected to the vertical lead screw 22. A vertical lead screw slider 24, which cooperates with the vertical lead screw 22, is disposed within the slide groove 21. Rotation of the vertical motor 23 drives the vertical lead screw 22 to rotate, thereby controlling the vertical lead screw slider 24 to slide in the vertical direction.

[0031] The first telescopic device 3 includes a first telescopic sleeve 31 fixedly mounted on a vertical lead screw slider 24 and a first telescopic rod 32 sliding along the inside of the first telescopic sleeve 31; the first telescopic sleeve 31 is set in the horizontal direction.

[0032] The second telescopic device 4 includes a second telescopic sleeve 41 fixedly disposed at the end of the first telescopic rod 32 and a second telescopic rod 42 sliding along the second telescopic sleeve 41; the second telescopic sleeve 41 is disposed in the horizontal direction and is perpendicular to the first telescopic sleeve 31. The universal adjustment assembly 5 includes a first rotating shaft 51, a second rotating shaft 52, and a mounting base 53; the first rotating shaft 51 is rotatably disposed at the end of the second telescopic rod 42, the mounting base 53 is disposed on the first rotating shaft 51, the second rotating shaft 52 is rotatably disposed on the mounting base 53, and the second rotating shaft 52 is perpendicular to the first rotating shaft 51. The supplementary light 6 is located at the end of the first rotating shaft 51.

[0033] In this application, a vertical moving device 2 allows the universal adjustment component 5 to move vertically (Z-axis direction); a first telescopic device 3 allows the universal adjustment component 5 to move along the X-axis; and a second telescopic device 4 allows it to move along the Y-axis. This enables the universal adjustment component 5 to move in the Z, X, and Y directions, allowing for precise adjustment of its position. Furthermore, the universal adjustment component 5 is equipped with a first rotating shaft 51 and a second rotating shaft 52. The first rotating shaft 51 can adjust the angle of the supplementary light 6 within a vertical range in real time, while the second rotating shaft 52 can adjust the angle of the supplementary light 6 within a horizontal range in real time. This allows the angle and brightness of the supplementary light 6 to be adjusted according to the actual color of the fabric.

[0034] In this embodiment, the supplementary light 6 consists of multiple high color rendering index LEDs with adjustable color temperature (2700K~6500K) and adjustable brightness. A high-precision color sensor and an ambient light sensor are located above the module to collect local color information of the fabric and surrounding ambient light. A central control PCB houses an ARM Cortex-M series microcontroller AI algorithm acceleration chip. This chip receives real-time data from the camera image processing system and sensors, calculates the optimal telescopic length, illumination angle, brightness, and color temperature, and then executes these parameters via the lower-level vertical movement device 2, the first telescopic device 3, the second telescopic device 4, and the universal adjustment assembly 5.

[0035] Specifically, a first drive screw 33 is provided inside the first telescopic sleeve 31, and a first drive slider 34 is provided on the first drive screw 33 to cooperate with it. The first telescopic rod 32 is fixedly connected to the first drive slider 34. A first drive motor 35 is provided at the end of the first telescopic sleeve 31 away from the first telescopic rod 32. When the first drive motor 35 rotates, it can drive the first drive screw 33 to rotate, thereby enabling the first drive slider 34 to move along the inside of the first telescopic sleeve 31, thereby controlling the extension and retraction of the first telescopic rod 32 within the first telescopic sleeve 31.

[0036] The first telescopic device 3 and the second telescopic device 4 have the same structure. Specifically, a second drive screw is provided inside the second telescopic sleeve 41, and a second drive slider is provided on the second drive screw to cooperate with it. The second telescopic rod 42 is fixedly connected to the second drive slider. A second drive motor 43 is provided at the end of the second telescopic sleeve 41 away from the second telescopic rod 42. When the second drive motor 43 rotates, it can drive the second drive screw to rotate, thereby enabling the second drive slider to move along the inside of the second telescopic sleeve 41, thereby controlling the extension and retraction of the second telescopic rod 42 within the second telescopic sleeve 41.

[0037] In one embodiment, a fixing post 36 is provided at the end of the first telescopic rod 32, and a fixing hole 361 is provided through the upper part of the fixing post 36. The second telescopic sleeve 41 passes through the fixing hole 361. A positioning bolt 362 is provided on the side wall of the fixing post 36, and the positioning bolt 362 passes through the fixing post 36 and abuts against the outer side wall of the second telescopic sleeve 41. In this embodiment, by placing the second telescopic sleeve 41 in the fixing hole 361, the second telescopic device 4 can be easily installed at the end of the first telescopic rod 32. In addition, by adjusting the position of the second telescopic sleeve 41 in the fixing hole 361, the maximum telescopic distance of the second telescopic rod 42 can be adjusted, thereby allowing the position of the second telescopic sleeve 41 in the fixing hole 361 to be adjusted according to actual conditions.

[0038] In one embodiment, a mounting bracket 54 is provided at the end of the second telescopic rod 42. Two parallel side plates 541 are provided on both sides of the mounting bracket 54. A first rotating shaft 51 is rotatably mounted on the two side plates 541. A side plate motor 55 is fixedly mounted on one of the side plates 541, and the output end of the side plate motor 55 is connected to the first rotating shaft 51. The side plate motor 55 can drive the first rotating shaft 51 to rotate, thereby causing the mounting seat 53 on the first rotating shaft 51 to swing in the vertical direction. In addition, a rib plate 542 is provided between the mounting bracket 54 and the side plate 541. The rib plate 542 can improve the stability of the connection between the mounting bracket 54 and the side plate 541 and improve the strength of the overall structure.

[0039] A motor 56 is installed on the mounting base 53. The motor 56 can drive the second rotating shaft 52 to rotate, thereby causing the supplementary light 6 at the end of the second rotating shaft 52 to swing in the horizontal direction.

[0040] In summary, by driving the first rotating shaft 51 to rotate via the side plate motor 55, the fill light 6 can be oscillated in the vertical direction. By driving the second rotating shaft 52 to rotate via the installed motor 56, the fill light 6 can be oscillated in the horizontal direction, thereby allowing for fine adjustment of the angle of the fill light 6 and enabling the fill light 6 to provide a better light source for the industrial camera.

[0041] In one embodiment, the supplementary light 6 is a ring-shaped supplementary light, which can provide a better supplementary light source and the illumination brightness can be more uniform.

[0042] In summary, this utility model enables the universal adjustment component 5 to move in the vertical direction (Z-axis direction) by setting the vertical moving device 2; the universal adjustment component 5 can move in the X-axis direction by setting the first telescopic device 3; and the universal adjustment component 5 can move in the Y-axis direction by setting the second telescopic device 4. Thus, the universal adjustment component 5 can move in the Z, X, and Y directions, thereby enabling precise adjustment of the position of the universal adjustment component 5.

[0043] In addition, by driving the first rotating shaft 51 to rotate via the side plate motor 55, the fill light 6 can be oscillated in the vertical direction. By driving the second rotating shaft 52 to rotate via the installed motor 56, the fill light 6 can be oscillated in the horizontal direction, thereby allowing for fine adjustment of the angle of the fill light 6 and enabling the fill light 6 to provide a better light source for the industrial camera.

[0044] Therefore, this application has the following advantages: (1) Excellent accuracy: With dual measurement by color sensor and ambient light sensor, and dynamic calculation by AI algorithm, the relative error of this device when detecting fabric color difference is ≤ ±0.2ΔE, which weakens the influence of ambient light interference.

[0045] (2) Real-time and fast: The total action time of telescopic and universal adjustment is ≤50ms, which can meet the high-speed detection requirements of fabric conveying speed ≤60m / min.

[0046] (3) Low maintenance cost: LED 41 lifespan ≥ 30,000 hours, sensor 42 / 43 can be automatically calibrated online; telescopic mechanism 20 cycle life ≥ 1 million times; only the optical lens and detection plate need to be cleaned every 3 months, and no other manual disassembly or assembly is required.
