[0002] In the textile production process, fabric quality detection is a crucial link. At present, there are some equipment and methods for fabric detection, which mainly use different sensing technologies and image processing technologies to detect fabric quality.

[0003] Existing fabric inspection devices usually use machine vision systems to scan fabrics and identify defects in fabrics through image analysis. However, these devices still have certain limitations in actual use.

[0004] The existing fabric detection devices, when in use, are not convenient for fully displaying the fabric under the detector, which easily leads to missed detection.

Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

[0032] See also Figure 1-5 , a cloth detection device in this embodiment includes a chassis 1, a first device frame 2, a second device frame 3, a mounting frame 4, a workbench 5 and a bottom plate 6, and an appearance detection mechanism is provided on the top of the workbench 5;

[0033] The appearance detection mechanism includes a driving motor 7 fixedly mounted on the left side of the chassis 1, a screw 8 fixedly connected to the output shaft of the driving motor 7, a moving block 9 threadedly sleeved on the outer surface of the screw 8, a connecting column 10 fixedly connected to the top of the moving block 9, a clamping frame 11 fixedly connected to the top of the connecting column 10, an electric push rod 12 fixedly mounted on the top of the clamping frame 11, a convex plate 13 fixedly connected to the output shaft of the electric push rod 12, a groove 26 opened on the inner bottom wall of the clamping frame 11, a first cylinder 14 fixedly mounted on the top of the first device frame 2, a lifting plate 15 fixedly connected to the output shaft of the first cylinder 14, and a detector 1 fixedly mounted on the bottom of the lifting plate 15 6. The high-resolution image acquisition module 17 installed at the bottom of the detector 16 and the deep learning image processing module 18 and the defect recognition module 19 installed inside the detector 16. When in use, the staff only needs to put one end of the cloth into the inner side of the clamping frame 11, and then, through the cooperation of the electric push rod 12, the convex plate 13 and the groove 26, the cloth inserted into the inside is clamped. Subsequently, the first cylinder 14 and the detector 16 are started, and through the cooperation of the drive motor 7, the screw 8, the moving block 9 and the connecting column 11, at this time, the detector 16 will drop to a suitable height, and the clamping frame 11 will pull the cloth and make it move continuously to the left side of the workbench 5.

[0034] Thereby, the complete shape and pattern of the cloth are displayed under the detector 16. Then, the detector 16 will obtain detailed images, conduct in-depth analysis and processing of the cloth that is constantly moving to the left through the cooperation of the high-resolution image acquisition module 17, the deep learning image processing module 18 and the defect recognition module 19. At the same time, the deep learning-based algorithm will accurately identify the defects in the image.

[0035] Among them, the inner side of the mounting frame 4 is rotatably connected with a feed roller 20, and the groove 26 matches the shape of the convex plate 13. By setting the feed roller 20, the effect of assisting the rolling of the cloth is achieved. The second cylinder 21 is fixedly installed on the top of the second device frame 3, and the output shaft of the second cylinder 21 is fixedly connected with a lifting frame 22, and the inner side of the lifting frame 22 is rotatably connected with a pressure roller 23.

By setting the base plate 6 and the movable wheels 28, the effect of stable support and easy movement is achieved.

[0039] The implementation principle of a cloth detection device in the embodiment of the present application is:

[0040] When in use, the staff first needs to drive the screw rod 8 to rotate counterclockwise through the driving motor 7, so that the clamping frame 11 moves to the right side of the workbench 5 to facilitate material discharge. When the clamping frame 11 moves to the extreme position, the staff only needs to put one end of the cloth into the inner side of the clamping frame 11, and then start the electric push rod 12, through the cooperation of the convex plate 13 and the groove 26, so as to clamp the cloth inserted into the inside. Subsequently, the first cylinder 14 and the detector 16 are started and the screw rod 8 is driven by the driving motor 7 to rotate clockwise. At this time, the detector 16 will drop to a suitable height, the clamping frame 11 will pull the cloth and make it move continuously to the left side of the workbench 5, so as to show the complete shape and pattern of the cloth under the detector 16, and then the detector 16 will obtain detailed images and conduct in-depth analysis and processing of the cloth that is continuously moving to the left through the cooperation of the high-resolution image acquisition module 17, the deep learning image processing module 18 and the defect recognition module 19.
