[0002] During the production and processing of packaging bags and other bag products, the quality of the stitching directly affects the firmness and appearance of the bags. Therefore, it is necessary to inspect the stitching of the bags. Through stitching inspection, stitching defects can be discovered and eliminated in time to ensure that the quality of the bags meets the standards, thereby reducing the defective rate and then reducing the waste cost.

[0003] At present, the existing bag stitch detection method mainly uses industrial cameras and other equipment to shoot the bag stitches, and then uses image recognition technology and AI algorithms to analyze them, so as to detect whether the stitches are complete, uniform, and free of loose threads or breaks. For example, a fabric stitch online detection device is disclosed on the Chinese Patent Network, and its publication number is CN216594830U. However, there are some defects and deficiencies that need to be improved: (1) The larger the size of the bag, the larger the image area that the camera needs to shoot, and when the existing detection device shoots the bag stitches, it is often difficult to adjust the camera height as needed, so it is difficult to apply to the stitch detection of bags of different sizes; (2) When shooting the bag stitches, the bag often tilts or deviates during the transmission and movement, making it difficult to align the bag stitches with the camera's shooting position, thereby affecting the shooting and analysis effect of the bag stitches.

[0039] The working principle of the utility model is:

[0040] When the utility model is in use, firstly, the electrical components in the device are connected to the control switch and power supply through the wires, and the lighting lamp 11 in the lamp trough 9 is energized, and then the bag product to be detected by the seam is introduced onto the transmission belt 5 through the bag inlet 8, and the transmission motor 3 is driven to drive the transmission roller 4 to rotate. After the transmission roller 4 rotates, it drives the transmission belt 5 to move together with the bag until the bag moves to the seam detection position, and then stops moving the transmission belt 5. Then, the seam of the bag is photographed by the industrial camera 14 to obtain the image of the seam of the bag. The industrial camera 14 can be connected to the image recognition system through the transmission line, so as to analyze the captured bag seam image with the help of image recognition technology and AI algorithm, so as to detect whether the seam is complete, uniform, and has no defects such as loose thread ends or breakage. Since the image recognition technology and AI algorithm are prior arts, they do not belong to the protection scope of the present technical method, and therefore will not be described in detail. When the size of the bag product When the size of the bag is larger, the first cylinder 12 can be driven to drive the mounting plate 13 and the industrial camera 14 to move upward, so as to increase the distance between the industrial camera 14 and the bag, so that the industrial camera 14 can capture a larger stitching area, thereby effectively improving the application range of the stitching detection device. When the transmission belt 5 drives the bag product to move, the limit plates 18 on both sides can play a limiting guiding role, so that the stitching of the bag is aligned with the shooting position of the industrial camera 14, so as to avoid the bag from shifting during the movement and affecting the shooting and analysis effect of the bag stitching. At the same time, by driving the second cylinder 19, the wheel frame 20 can be driven to move up and down together with the pressure wheel 21. When the pressure wheel 21 contacts the surface of the bag product, the downward pressure applied by the pressure wheel 21 can be used to flatten the stitching of the bag to avoid the stitching from warping and shooting and analysis effect. When the entire stitching detection work is completed, the bag product can be taken out from the transmission belt 5.
