[0026] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model.

[0027] Therefore, the following detailed description of the embodiments of this utility model is not intended to limit the scope of the claimed utility model, but merely illustrates some embodiments of the utility model. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without inventive effort are within the scope of protection of this utility model. It should be noted that, unless otherwise specified, the embodiments, features, and technical solutions in the embodiments of this utility model can be combined with each other.

[0028] It should be noted that similar labels and letters in the following figures indicate similar items. Therefore, once an item is defined in one figure, it does not need to be further defined and explained in subsequent figures.

[0029] like Figures 1-3 As shown, this embodiment proposes a fully automatic continuous straw visual inspection device, including a visual inspection machine 1 and a visual camera 2. The inner end of the visual inspection machine 1 is provided with a conveyor belt 3, the outer end of the conveyor belt 3 is provided with rubber pads 4, the left end of the conveyor belt 3 is provided with a rotating cylinder 7, the outer end of the rotating cylinder 7 is provided with a Velcro layer 6, the outer end of the Velcro layer 6 is provided with a towel pad 5, the lower end of the rotating cylinder 7 is provided with a rotating shaft 8, the outer end of the rotating shaft 8 is provided with a linkage dust collection pipe 9, and the lower end of the linkage dust collection pipe 9 is provided with a dust collection trough 10.

[0030] The friction between the rubber pad 4 and the towel pad 5 generates electrostatic adsorption, attracting the rows of straws: Utilizing the principle of electrostatic adsorption, a stable adsorption force can be provided for lightweight rows of straws. Compared to other complex fixing or limiting devices, this method is simple and effective, requiring no additional complex mechanical structures to ensure the position of the rows of straws on the conveyor belt 3. Moreover, electrostatic adsorption can adapt to rows of straws of different sizes, exhibiting good versatility.

[0031] The rubber pad 4 and the towel pad 5 on the left side are in frictional contact. The inner end of the towel pad 5 is attached to the Velcro layer 6. The inner end of the Velcro layer 6 is fixed to the outer end of the rotating cylinder 7.

[0032] The Velcro layer 6 connects the towel pad 5 to the rotating drum 7: the Velcro connection makes the installation and removal of the towel pad 5 very convenient. When the towel pad 5 becomes dirty or worn after a period of use, it can be easily peeled off from the rotating drum 7 for replacement or cleaning, without complicated tools or operations, greatly improving the convenience and efficiency of maintenance.

[0033] A slow-speed motor is provided at the outer end of the rotating cylinder 7, and support plates are provided at both ends of the rotating cylinder 7. The lower end of the support plate is movably positioned relative to the rotating shaft 8.

[0034] The rotating drum 7 is driven by a slow-speed motor: the slow-speed motor can precisely control the rotation speed of the rotating drum 7, thereby stably controlling the friction speed and force between the towel pad 5 and the rubber pad 4. The appropriate rotation speed can ensure that enough electrostatic adsorption is generated to attract the row of straws, without causing the row of straws to fall off or causing other problems due to excessive friction caused by excessive speed.

[0035] A connecting block is provided between the outer end of the rotating shaft 8 and the linkage dust collection pipe 9. The rotating shaft 8 drives the connecting block to move, and the connecting block is fixedly connected to the linkage dust collection pipe 9.

[0036] The upper end of the linkage dust collection pipe 9 is in contact with the towel pad 5, and the lower end of the linkage dust collection pipe 9 is movably connected to the upper end of the dust collection trough 10. The dust collection trough 10 is rotated and positioned between the support plates.

[0037] The linked dust collection pipe 9 works in conjunction with the towel pad 5 to collect dust: The linked dust collection pipe 9 can promptly collect dust generated during the friction between the towel pad 5 and the rubber pad 4. This not only maintains a clean working environment but also prevents dust from adhering to the continuous suction pipes to be inspected, thus affecting the accuracy of visual inspection. By sucking the dust into the dust collection tank 10, centralized dust processing is achieved, facilitating regular cleaning. Without a dust collection device, dust may scatter on the workbench and the surface of the continuous suction pipes, leading to misjudgments in visual inspection, such as misidentifying dust as product defects.

[0038] When this application is in use: the towel pad 5 wrapped by the Velcro layer 6 at the outer end of the rotating cylinder 7 rotates under the drive of the slow motor and rubs against the rubber pad 4 at the outer end of the conveyor belt 3. The rubber pad 4 generates static electricity through friction, and the static electricity attracts the continuous suction tubes that need to be detected during feeding, ensuring that the lightweight continuous suction tubes move stably on the conveyor belt 3 without deviating.

[0039] Furthermore, the upper opening of the linkage dust collection pipe 9 is in contact with the lower end of the towel pad 5, so as to collect the dust brought out by the friction between the towel pad 5 and the rubber pad 4 and suck it into the dust collection tank 10, which helps to reduce defects during visual inspection.

[0040] The above embodiments are only used to illustrate the present utility model and are not intended to limit the technical solutions described in the present utility model. Although the present utility model has been described in detail with reference to the above embodiments, the present utility model is not limited to the specific embodiments described above. Therefore, any modifications or equivalent substitutions to the present utility model, and all technical solutions and improvements that do not depart from the spirit and scope of the utility model, are covered within the scope of the claims of the present utility model.
