Description

Technical Field

[0001] This invention relates to the field of garment manufacturing and quality inspection, and in particular to a garment quality inspection device and its inspection system for garment factories. Background Technology

[0002] During the production process of ready-made garments, from fabric procurement, cutting and sewing to finishing, quality problems such as size deviation, substandard color fastness, sewing defects, and harmful substance residues may occur due to unstable raw material quality, differences in the precision of production equipment, and worker operation errors. Through garment inspection, unqualified products can be detected and rejected in a timely manner, ensuring that ready-made garments entering the market meet quality standards and safety regulations.

[0003] With the rapid development and intelligent transformation of the garment manufacturing industry, garment quality inspection has become a key link in ensuring product quality. Traditional inspection methods mainly rely on manual visual inspection, which suffers from problems such as low efficiency, susceptibility to subjective factors leading to missed or false detections, and continuously rising labor costs. In recent years, although semi-automatic inspection equipment combining simple mechanical devices and basic sensors, or machine vision systems using cameras and image processing algorithms have emerged in an attempt to improve inspection efficiency, the former has incomplete coverage of inspection items and limited automation, while the latter still faces technical bottlenecks such as insufficient inspection accuracy, poor adaptability, high algorithm training costs, and stringent requirements for garment folds and flatness when dealing with complex fabric textures, varied colors, or special garment styles. It is difficult to achieve comprehensive, accurate, and stable automated quality inspection on high-speed production lines. Summary of the Invention

The guide rail is located below the threaded rod. There are two guide blocks, which are fixedly connected to the bottom of the two threaded blocks respectively. The second support rod is located directly below the first support rod.

[0009] Preferably, the positioning module includes two mounting boxes, which are fixedly connected to opposite sides of two second outer shells. The inner wall of the mounting box is fixedly connected to a pulley, and the inside of the mounting box is slidably connected to a slider extending to its outer side. A spring is fixedly connected between the top of the slider and the top wall of the inner wall of the mounting box. A wooden clip is fixedly connected to the top of the slider located on the outer side of the mounting box, and a pull rope passing through the pulley is fixedly connected to the bottom of the slider.

[0010] Preferably, the detection assembly includes a first light source, a second light source is fixedly connected to the outer side of the gantry, a third light source is fixedly connected to the inner side of the gantry, an industrial camera is fixedly connected to the top of the detection platform, and an industrial PC is fixedly connected to the outer side of the detection platform.

[0011] Preferably, the first light source is fixedly connected to the bottom of the mounting box and located in front of the connecting rod. There are two second light sources, which are located on the left and right sides of the gantry respectively. The industrial camera is located in front of the gantry. The industrial PC integrates a data processing module, a control module, and an output module. The data processing module includes image processing algorithms and machine learning models.

[0012] On the other hand, this application also provides a garment quality inspection system for a garment factory, including: S1, stretching the garment flat, putting the garment on the two first support rods of the first stretching module, and opening the two first support rods to the sides by controlling the first servo motor to stretch the shoulders and sleeves of the garment, and then adjusting the distance between the two second support rods by activating the second servo motor of the second stretching module to stretch the body of the garment.

S4. Output of test results: The output module integrated into the industrial PC displays and generates a test report.

[0013] In summary, the present invention provides a garment quality inspection device and system for garment factories, which has the following beneficial effects: 1. The garment quality inspection system and its inspection device of this garment factory, through the first servo motor driving the meshing first gear and second gear, can synchronously control the rotation angle of the two connecting rods, thereby causing the first support rod installed at the bottom of the first shell to open outward to adapt to the position of the garment's shoulder. Subsequently, the first electric push rod pushes the first support rod to extend horizontally, which can flatten sleeves of different lengths, providing a stable and accurate reference surface for inspection. Through the second servo motor driving the threaded rod with reverse threads, the two threaded blocks are driven to move precisely synchronously in opposite directions or towards each other on the guide rail, thereby controlling the distance between the two second support rods. Combined with the second electric push rod driving the second support rod to lift and lower, it realizes the adaptive opening of the garment body or hem in the horizontal and vertical directions. Working in conjunction with the first opening module, it ensures that the garment is fully flat as a whole.

[0014] 2. The garment factory's garment quality inspection system and its inspection device use wooden clamps to hold the corners of the garment. When the second support rod moves outward to open the garment, the mounting box fixed to the second outer shell moves accordingly. A pull rope passes around a pulley and connects to a slider. Under the synergistic action of a spring, the slider and the wooden clamp on its top can be automatically adjusted and driven to move downward and outward. This allows for precise secondary positioning and pulling down to flatten the garment while it is being unfolded, effectively eliminating wrinkles and shifts in the hem area and ensuring the flatness of the garment's hem area. This provides a crucial guarantee for the subsequent acquisition of high-quality, distortion-free inspection images by the industrial camera.

[0015] 3. The garment factory's garment quality inspection system and its inspection device, through a first light source arranged at the bottom of the mounting box, second light sources on the left and right sides of the gantry frame, and a third light source on the inner side, constitute a multi-angle combined lighting system. It can highlight different types of defects from multiple directions such as the front, side, and back. The industrial camera acquires high-definition images under this optimized lighting, and the algorithms and models integrated into the industrial PC are analyzed to finally generate a report, realizing full automation and intelligence from image acquisition to result output.

[0018] The specific embodiments of the present invention will now be described in further detail with reference to the accompanying drawings.

[0019] Example 1 like Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 and Figure 6 As shown, the present invention provides a technical solution: a garment quality inspection device for a garment factory, including an inspection table 1, a first opening module 2 and a second opening module 3 are provided on the top of the inspection table 1, an inspection component 4 is provided on the first opening module 2, and a positioning module 5 is provided on the second opening module 3. The first expansion module 2 includes a gantry frame 201. A mounting box 202 is fixedly connected to the front side of the gantry frame 201. A first servo motor 203 is fixedly connected to the top of the mounting box 202. A first gear 204 and a second gear 205 are rotatably connected inside the mounting box 202. A connecting rod 206 is fixedly connected to the bottom of both the first gear 204 and the second gear 205. A first housing 207 is fixedly connected to the bottom of the connecting rod 206. A first electric push rod 208 is fixedly connected inside the first housing 207. A first support rod 209 is fixedly connected to the output end of the first electric push rod 208.

[0020] like Figure 3 and Figure 4 As shown, the gantry 201 is fixedly connected to the top of the testing table 1. The first gear 204 and the second gear 205 mesh with each other. The output shaft of the first servo motor 203 is fixedly connected to the first gear 204. The fixed gantry 201 provides a stable support foundation for the upper support mechanism. At the same time, by driving the meshing first gear 204 and the second gear 205 with a single first servo motor 203, it is possible to ensure that the two gears achieve precise synchronous reverse rotation, thereby providing a stable and reliable power source for the subsequent angle adjustment of the support rod.

[0021] like Figure 3 and Figure 4 As shown, the connecting rod 206 is installed vertically, and the first outer shell 207 is installed at an angle with the connecting rod 206 at an obtuse angle. The first support rod 209, fixed inside the first outer shell 207, presents a preparatory posture that conforms to the natural slope of the human shoulder when it is open, so that it can support and flatten the shoulder and sleeve area more smoothly and closely after being inserted into the sleeve, effectively avoiding damage to the clothing structure during the opening process.

[0022] like Figure 5 As shown, the second stretching module 3 includes a second servo motor 301. The output shaft of the second servo motor 301 is fixedly connected to a threaded rod 302. A threaded block 303 is threadedly connected to the outer side of the threaded rod 302. A guide rail 304 is fixedly connected to the top of the detection table 1. A guide block 305 is slidably connected to the outer side of the guide rail 304. A second outer shell 306 is fixedly connected to the top of the threaded block 303. A second electric push rod 307 is fixedly connected inside the second outer shell 306. A second support rod 308 is fixedly connected to the output end of the second electric push rod 307. The second servo motor 301 drives the threaded rod 302 to control the horizontal spacing of the second support rod 308 to stretch the garment body. The second electric push rod 307 controls its height to flatten the hem, thereby achieving two-dimensional precise stretching of the lower half of the garment.

[0023] like Figure 1 , Figure 2 , Figure 5 and Figure 6 As shown, the second servo motor 301 is fixedly connected to the top of the testing table 1. A mounting plate rotatably connected to the threaded rod 302 is fixedly connected to the top of the testing table 1. The threaded rod 302 has two threads of equal length and opposite directions. Two threaded blocks 303 are located on the two threads respectively. Driven by one second servo motor 301, the two threaded blocks 303 and their support rod mechanisms can be synchronously, precisely, and automatically controlled to move symmetrically in opposite directions or towards each other. This ensures that the garment body is evenly stressed during the unfolding process, resulting in efficient and coordinated movements. The guide rail 30... Located below the threaded rod 302, there are two guide blocks 305, each fixedly connected to the bottom of one of the two threaded blocks 303. The second support rod 308 is located directly below the first support rod 209. The guide rail 304 and the guide block 305 provide a highly stable sliding pair for the horizontal expansion movement of the threaded block 303, effectively preventing jamming and shaking. At the same time, the facing arrangement of the first support rod 209 and the second support rod 308 forms a complete three-dimensional support frame, ensuring that the garment has a regular shape and uniform tension after being stretched, laying the foundation for high-quality image acquisition.

[0024] like Figure 1 , Figure 2 and Figure 6 As shown, the positioning module 5 includes two mounting boxes 501, each fixedly connected to the opposite sides of two second outer shells 306. A pulley 502 is fixedly connected to the inner wall of each mounting box 501. A slider 503 extending to the outer side of the mounting box 501 is slidably connected inside the mounting box 501. A spring 504 is fixedly connected between the top of the slider 503 and the inner top wall of the mounting box 501. A wooden clip 505 is fixedly connected to the top of the section of the slider 503 located on the outer side of the mounting box 501. A pull rope 506 passing through the pulley 502 is fixedly connected to the bottom of the slider 503. When the second support rod 308 moves outward to open the garment, it is fixed to... The mounting box 501 on the second housing 306 moves accordingly, and the pull rope 506 passes around the pulley 502 and connects to the slider 503. Under the synergistic action of the spring 504, it can automatically adjust and drive the slider 503 and the wooden clamp 505 on its top to move downward and outward. Thus, while the second support rod 308 unfolds the garment, the wooden clamp 505 clamps the corners of the garment on both sides, performing precise secondary positioning and pulling down to flatten them. This effectively eliminates wrinkles and offsets in the hem area, ensuring the flatness of the garment's hem area and providing a key guarantee for the subsequent acquisition of high-quality, distortion-free inspection images by the industrial camera 404.

[0025] like Figure 1 and Figure 2As shown, the detection component 4 includes a first light source 401, a second light source 402 fixedly connected to the outside of the gantry 201, a third light source 403 fixedly connected to the inside of the gantry 201, an industrial camera 404 fixedly connected to the top of the detection table 1, and an industrial PC 405 fixedly connected to the outside of the detection table 1. By arranging multiple types of light sources at different positions on the gantry 201, differentiated optimal lighting schemes can be provided for the back, sides, and front of the garment. Combined with the industrial camera 404 for image capture, a complete machine vision imaging system capable of adapting to various defect detection needs is formed.

[0026] like Figure 1 and Figure 2As shown, the first light source 401 is fixedly connected to the bottom of the mounting box 202 and located in front of the connecting rod 206. The first light source 401 illuminates the garment vertically from directly above, evenly illuminating the surface and facilitating the detection of large-area stains, color differences, and printing defects. Two second light sources 402 are located on the left and right sides of the gantry 201, respectively. The second light sources 402 sweep across the garment surface in a nearly horizontal direction, creating distinct shadows on three-dimensional defects such as seams, wrinkles, and broken needles, thus enabling efficient identification. The industrial camera 404 is located directly in front of the gantry 201. The third light source 403 illuminates the garment from behind, producing clear outlines and optimal illumination. For dimensional measurement, the industrial PC 405 integrates a data processing module, a control module, and an output module. The data processing module includes image processing algorithms and machine learning models. The image processing algorithms refer to a series of digital image processing technologies developed based on computer vision libraries such as OpenCV, including edge detection and texture analysis algorithms. In this embodiment, these algorithms are directly called by the data processing module integrated within the industrial PC 405 to preprocess and extract features from the high-definition garment images acquired by the industrial camera 404 under multi-angle optimized illumination provided by the first light source 401, the second light source 402, and the third light source 403. Specifically, the edge detection algorithm is used to accurately identify the garment outline after it has been stretched open by the first support rod 209 and the second support rod 308, thereby enabling objective size measurement. Simultaneously, the texture analysis algorithm is used to initially screen for obvious defects on the fabric, such as weave flaws or stains, laying the foundation for subsequent, more refined classification. The machine learning model is a mathematical model that can automatically learn patterns from data and make predictions. In this embodiment, it specifically refers to a model that uses a convolutional neural network (CNN) for defect classification. This model is also deployed in the data processing module of the industrial PC405, receiving features preprocessed by the image processing algorithm. The core application of the data and original image areas lies in the fact that the model, by learning from a large number of labeled garment defect samples such as skipped stitches, holes, and uneven sewing, can intelligently and comprehensively judge the features presented under specific lighting conditions, such as large-area stains, color differences and printing defects highlighted by the top light of the first light source 401, the seam shadows highlighted by the side light of the second light source 402, and the clear outlines highlighted by the back light of the third light source 403. Finally, it can accurately and automatically classify and identify complex defects such as sewing quality and fabric flaws of the garments fixed and flattened by the first stretching module 2 and the second stretching module 3, thereby greatly improving the accuracy and efficiency of detection.

[0027] Example 2 Please see Figure 7The present invention provides another technical solution: a garment quality inspection system for a garment factory, comprising: S1, flattening the garment, placing the garment on the two first support rods 209 of the first stretching module 2, and opening the two first support rods 209 to both sides by controlling the first servo motor 203 to stretch the shoulders and sleeves of the garment, and then adjusting the distance between the two second support rods 308 by activating the second servo motor 301 of the second stretching module 3 to stretch the body of the garment; S2. Multi-light source image acquisition: The first light source 401, the second light source 402 and the third light source 403 are lit sequentially or synchronously to provide the best lighting for the stretched garment from different angles. The industrial camera 404 captures high-definition images of various parts of the garment under each lighting condition. S3, Image Processing and Defect Analysis: The control module integrated into the industrial PC405 coordinates the workflow of each module, while the data processing module is used to analyze the captured high-definition images and identify defects. S4. Output of test results: The output module integrated into the industrial PC405 displays the test results and generates a test report.

[0028] In use, during the garment stretching stage, the operator places the garment to be inspected from the neckline onto the two parallel first support rods 209 of the first stretching module 2. The system is then started, and the control module integrated into the industrial PC 405 issues a command to drive the first servo motor 203. The output shaft of the first servo motor 203 drives the meshing first gear 204 and second gear 205 inside the mounting box 202 to rotate synchronously in opposite directions. This, in turn, adjusts the angle of the first support rods 209 connected to the first outer shell 207 and the internal first electric push rod 208 via the connecting rod 206, causing them to unfold outwards. This effectively stretches and flattens the shoulders and sleeves of the garment. Simultaneously, the control module also controls the second stretching module 3 to open... At the start of operation, while the second servo motor 301 is activated, the hem of the garment is clamped with a wooden clamp 505. The second servo motor 301 drives the threaded rod 302, which has two sections of oppositely oriented threads on its output shaft, to rotate. Under the stable guidance of the guide rail 304 and the guide block 305, the two threaded blocks 303 that mesh with the threaded rod 302 move synchronously in opposite directions, causing the second outer shell 306 fixed to its top and the second electric push rod 307 inside to move laterally. This adjusts the horizontal distance between the second support rod 308, which is fixedly connected to the output end of the second electric push rod 307, to open up the body of the garment. Then, the second electric push rod 307 is activated, pushing the second support rod 308 upward to further flatten the hem. When the second support rod 308 moves outward... When the garment is unfolded, the mounting box 501, fixed to the second outer shell 306, moves accordingly. A pull rope 506 passes over a pulley 502 and connects to a slider 503. With the assistance of a spring 504, the slider 503 and its top wooden clip 505 automatically adjust and drive downward and outward movement, thus precisely repositioning and flattening the corners of the garment. At this point, the garment is stably and smoothly fixed to the inspection station by the three-dimensional support frame formed by the first support rod 209, the second support rod 308, and the wooden clip 505. Next, the multi-light source image acquisition stage begins. The control module sequentially or synchronously illuminates the first light source 401 located at the bottom of the mounting box 202 for uniform front illumination, and the light sources located on the left and right sides of the gantry 201. A second light source 402 is used to highlight lateral three-dimensional defects, and a third light source 403, located inside the gantry 201, is used to provide backlight contour illumination. An industrial camera 404 quickly captures high-definition digital images of various parts of the stretched garment under each specific lighting condition and transmits the image data to an industrial PC 405. Subsequently, the core stage of image processing and defect analysis begins. The data processing module integrated into the industrial PC 405 starts operating, and its built-in OpenCV-based image processing algorithm preprocesses and extracts features from the received images. The machine learning model trained on a convolutional neural network (CNN) deployed in the data processing module performs in-depth analysis of the preprocessed image features and the original image regions.The system intelligently identifies and classifies various complex defects such as poor stitching, skipped stitches, holes, stains, and color differences. Finally, in the output stage, the output module within the industrial PC405 integrates the analysis results, clearly presents the inspection report on the display, and can store or transmit the results to the factory management system.
