Description

Technical Field

[0001] The invention relates to the field of clothing production detection, and in particular to a clothing defect detection method and a device thereof. Background Art

[0002] In today's global market environment, the apparel industry is highly competitive, and consumers are increasingly demanding clothing quality. With the rapid development of intelligent manufacturing and automation technology, apparel manufacturers are facing multiple pressures to improve production efficiency, reduce costs, and ensure product quality. Efficient and accurate clothing defect detection technology has become a key demand for the development of the industry. It is of great significance to improve the market competitiveness of enterprises, reduce the defective rate, enhance the brand image, and meet consumers' expectations for high-quality clothing. It is also in line with the trend of modern manufacturing industry's transformation towards intelligence and refinement.

[0003] At present, there are many problems in the field of clothing defect detection. Many companies still rely on manual visual inspection, and inspectors are prone to fatigue after working for a long time, resulting in low detection accuracy and efficiency. In addition, it is difficult to unify the standards for manual inspection and is greatly affected by subjective factors. Some existing inspection equipment has a single function and can only detect specific types of defects, such as color defects or airtightness problems, and cannot fully meet diverse inspection needs. In addition, the equipment has poor adaptability, and it is difficult to quickly adjust the inspection parameters and modes to adapt to clothing of different materials and styles, which limits its scope of application in actual production and increases the quality control cost and time cost of the enterprise.

[0004] The traditional clothing inspection method is to manually lay the clothing flat on a simple inspection table and observe with the naked eye whether there are obvious defects such as damage, stains, color difference, etc. on the surface of the clothing. For color inspection, it is simply judged by experience and lacks accurate color analysis tools. In terms of air tightness inspection, a simple method of observing whether there is air leakage after inflation is usually adopted. There are no accurate inspection instruments and quantitative judgment standards. The entire inspection process lacks systematicity and scientificity and relies entirely on manual operation. It is not only inefficient, but also difficult to detect some minor defects, which can easily lead to defective products entering the market, affecting the company's reputation and economic benefits.

[0005] Existing technologies have serious deficiencies in detection accuracy. Manual visual inspection cannot detect minor defects, such as tiny pinholes and slight color changes, resulting in a high defect rate and increased production costs and quality risks. The detection efficiency is low and manual inspection is slow, making it difficult to meet the needs of large-scale production and extending the production cycle. The single function requires companies to equip themselves with a variety of testing equipment, increasing equipment procurement and maintenance costs. The equipment has poor adaptability and cannot flexibly respond to changes in different clothing styles and materials, restricting the company's production flexibility and market response speed, which is not conducive to the modernization and competitiveness of the clothing industry.

DETAILED DESCRIPTION

[0032] The following will be combined with the accompanying drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and cannot be understood as limiting the present invention.

[0033] The following describes an embodiment of the present invention based on its overall structure.

[0034] A clothing defect detection method and device, such as Figure 1-7As shown, it includes a tooling plate 1, one end of which is provided with a connecting cross bar 3, and the connecting cross bar 3 is provided with a guide rod 2 at the center position of one end of the tooling plate 1, and a telescopic rod 4 is movably provided at the bottom of the guide rod 2. A slot 26 is provided on the tooling plate 1, and a defect detection device 31 is provided in the slot 26. A detection protection partition 7 is provided on the top of the slot 26 to cooperate with the defect detection device 31, and the defect detection device 31 is protected by the detection protection partition 7. The tooling plate 1 is provided with a plurality of slots 26, and a sensing device 29 is provided in the placement slot 30. A sensing protection partition 8 is provided on the top of the placement slot 30 to cooperate with the sensing device 29, and the sensing device 29 is protected by the sensing protection partition 8.

[0035] A limit plate 6 is arranged on the tooling plate 1 below the detection and mounting plate 5, and a guide groove 10 is symmetrically provided on the tooling plate 1 to cooperate with the limit plate 6. A sliding block 28 is arranged at the bottom of the limit plate 6 to cooperate with the guide groove 10, and a rotating rod 27 is arranged in the guide groove 10 to cooperate with the sliding block 28, and a motor is arranged in the guide groove 10 to cooperate with it.

[0036] The bottom of the slot 26 is provided with a supporting base plate 9 to cooperate with the defect detection device 31 , and the supporting base plate 9 is connected to the sensing device 29 via a data line 32 .

[0037] The bottom of the tooling plate 1 is provided with a movable rod 12 to cooperate with the supporting bottom plate 9 .

[0038] In coordination with the above structure, a detection device is provided at the bottom of the detection mounting plate 5, and a rotating shaft 11 is provided at the bottom of the detection mounting plate 5 to cooperate with the detection device, and the detection device is arranged in a "T" shape, and the detection device is respectively connected to the first detection device 13, the second detection device 14 and the third detection device 15, and the detection device facing downward is controlled by the rotation of the rotating shaft 11. As the telescopic rod 5 moves, different sensing devices 29 are triggered to select different detection devices for detection, wherein a central rotating shaft 22 is provided at the center position of the first detection device 13, and a control motor 21 is provided in the first detection device 13 to cooperate with the central rotating shaft 22, and a plurality of color filters 24 are arranged around the central rotating shaft 22, and the central rotating shaft 22 is connected to the color filter 24 by a connecting rod 23, and an image acquisition device 20 is provided in the first detection device 13 to cooperate with the color filter 24, and a through slot 25 is provided on the first detection device 13 to cooperate with the image acquisition device 20, and the image acquisition device 20 can be replaced according to different clothing detection requirements through different color filters 24.

[0039] At the same time, the third detection device 15 is provided with a groove, and a sensing plate 17 is movably provided in the groove. A second conductor 18 is provided on a surface of the sensing plate 17 close to the third detection device 15. A first conductor 16 is provided on the third detection device 15 to cooperate with the second conductor 18. A reset spring 19 is provided between the sensing plate 17 and the third detection device 15. When performing an airtightness test, the distance between the first conductor 16 and the second conductor 18 changes with the movement of the sensing plate 17. Therefore, in the airtightness test, the gas of the clothes contacts the sensing plate 17, thereby testing the airtightness of the clothes.

[0040] During actual use, place the clothing defect detection device on a stable workbench with suitable lighting and easy operation, and ensure that the tooling plate 1 is placed firmly without shaking or tilting. Check whether the connection between the crossbar 3, the guide rod 2, the telescopic rod 4 and other components is firm, and whether each movable component can operate flexibly, such as the rotating shaft 11, the rotating rod 27, etc. Check whether the detection protection partition 7 and the induction protection partition 8 are installed in place to provide good protection for the defect detection device 31 and the induction device 29. Check whether the defect detection device 31 in the slot 26 and the induction device 29 in the placement slot 30 are working properly, and whether the data line 32 is connected stably to ensure the accuracy and timeliness of data transmission. Perform a power-on test on the motor to check whether it can drive the rotating rod 27 normally, so that the sliding block 28 at the bottom of the limit plate 6 moves smoothly in the guide slot 10. At the same time, confirm the operation of the control motor 21 in the first detection device 13, ensure that the central rotating shaft 22 can drive the color filter 24 to switch normally, and the image acquisition device 20 can clearly acquire images, so as to make full preparations for subsequent detection;

[0041] Select the garment to be inspected and place it flat on the tooling board 1, ensuring that the garment covers the slot 26 and the placement slot 30 area, so that the detection device and the sensing device can fully detect all parts of the garment. According to the size and shape of the garment, fix it by adjusting the position of the limit plate 6, start the motor, and the motor drives the rotating rod 27 to rotate, so that the sliding block 28 moves in the guide slot 10, and adjust the limit plate 6 to a suitable position so that it fits closely to the edge of the garment to prevent the garment from shifting during the inspection process, which affects the accuracy of the inspection results;

[0042] According to the material, style and inspection requirements of the clothing, corresponding inspection parameters are set in the control system connected to the inspection device, such as color inspection mode, air tightness inspection standard, etc. When color-related defect inspection is required, the control system will rotate the inspection device through the rotating shaft 11 according to the preset instructions, and select the first inspection device 13 for inspection. At the same time, the control motor 21 is started to drive the central rotating shaft 22 to rotate, and the appropriate color filter 24 is switched, so that the image acquisition device 20 can accurately capture the clothing image under a specific color channel, so as to more accurately detect color defects, color differences and other problems;

[0043] Start the telescopic rod 4, which drives the detection mounting plate 5 to descend, so that the detection device is close to the surface of the clothing. As the detection mounting plate 5 descends, when it reaches a certain position, the corresponding sensing device 29 will be triggered, and the sensing device 29 will transmit the signal to the control system. The control system determines the current detection position and the required detection items according to the signal, and further adjusts the working state of the detection device. For example, when performing an airtightness test, the sensing plate 17 on the third detection device 15 will contact the clothing. When gas is filled into the clothing, the gas pressure will move the sensing plate 17, changing the distance between the first conductor 16 and the second conductor 18, thereby generating an electrical signal change. The signal is transmitted to the control system to determine whether the airtightness of the clothing meets the standard. During the entire detection process, the detection device will comprehensively scan and detect the clothing according to the preset path and method, and transmit the collected data to the control system in real time for analysis and processing;

[0044] The control system quickly analyzes and processes the data transmitted back by the detection device to determine whether the clothing has defects and the type, location, severity, etc. of the defects. The detection results are recorded in detail, including the qualified clothing batches and defective clothing numbers, defect details, etc., and a detection report is generated to facilitate subsequent traceability and management of clothing quality. For defective clothing, it is classified and marked according to the defect situation to facilitate subsequent rework or scrapping;

[0045] After completing the inspection task of a batch of clothing, turn off the power of the equipment, clean up the debris and dust on the tooling board 1, and prevent them from entering the slots 26 and the placement slots 30 to affect the normal operation of the detection device and the sensing device. Check the wear of each component, check and replace the wearing parts such as the color filter 24 and the sensing plate 17, and at the same time, maintain and maintain the motor, control motor 21 and other equipment to ensure the long-term stable operation and detection accuracy of the equipment, prepare for the next inspection operation, improve the service life and work efficiency of the equipment, reduce production costs, and ensure the efficient and accurate inspection of clothing;
