[0044] In order to solve the above problems, combined withFigures 1-5 As shown, the embodiment provides a fabric automatic detection device, which comprises a frame 1, a roller assembly and a detection assembly. The roller assembly is rotationally arranged in the frame 1, the fabric to be detected is wound on the roller assembly, and the detection assembly is arranged on the frame 1 and located above the roller assembly. The detection assembly comprises an imaging device and an image processing module. The imaging device is communicatively connected with the image processing module. The imaging device is used for scanning and imaging the fabric to be detected, and the image processing module is used for analyzing the surface stains and damages of the imaging.

The image processing module analyzes the stains and damages of the image scanned by the imaging device, so as to realize automatic detection, and the defect detection information is fed back in time through the image processing module, without the need of inkjet marking on the fabric to be detected, thereby protecting the fabric to be detected and avoiding secondary damage.

[0046] Specifically, the imaging device comprises a line scan camera 4, which is arranged towards the roller assembly. The line scan camera 4 is used for scanning and imaging the fabric to be detected row by row.

[0047] Preferably, the line scan camera 4 is a CIS line scan camera. The width of the CIS line scan camera can be up to 2300 mm. One camera can realize wide scanning. The detection accuracy can reach 10 μm, the detection speed can reach 150 K, the CIS line scan camera is internally integrated with a micro lens and a light source, and the working distance is short, that is, the distance between the line scan camera 4 and the roller assembly is small, and the line scan camera 4 closely scans the fabric to be detected. The structure is compact, occupies small space, is easy to install, and is simple to operate. The 1:1 imaging is free of distortion, avoids the resolution loss problem caused by image distortion and edge blurring, and simultaneously reduces the burden of subsequent image processing.

One end of the support rod 121 is arranged on the base 11, the sleeve rod 122 is sleeved on the other end of the support rod 121, the other end of the sleeve rod 122 away from the support rod 121 is connected with the line-scan camera 4, and the fixing member is connected with the support rod 121 and the sleeve rod 122 to fix the support rod 121 and the sleeve rod 122. Specifically, the peripheral side of the sleeve rod 122 is provided with a mounting groove 1221 communicating with the inside thereof, the mounting groove 1221 is preferably a waist-shaped groove and is a sunken groove structure, and the peripheral side of the support rod 121 is provided with a plurality of mounting holes 1211, which are spaced apart in the vertical direction. The fixing member extends into the mounting groove 1221 and is connected with the mounting hole 1211 of the corresponding height, and the fixing member is preferably a latch rod. By adjusting the sleeving depth of the sleeve rod 122 on the support rod 121, the distance between the line-scan camera 4 and the main roller 2 is adjusted to adapt to different widths of the fabric to be detected, and the versatility is good.

[0055] In other embodiments, the lifting supports 12 can be one, two, three, five or even more, and the number of the lifting supports 12 is not limited in the embodiment, and the lifting supports 12 can also be telescopic cylinders or the like.
