Bandages may encounter various problems during the production process, such as missing yarns, broken threads, etc. These defects are often difficult to detect when the bandages are not stretched. Traditional detection methods mainly rely on manual visual inspection, that is, by stretching the bandages to the normal use size with tools such as sleeves, and using the naked eye to identify defects. This method has the following major problems: 1. Low efficiency: Manual inspection requires a lot of manpower and is slow, which cannot meet the needs of efficient production. 2. Low accuracy: Naked eye inspection is affected by multiple factors such as the operator's vision and distraction, and is prone to omissions, resulting in defective products flowing into the next process. 3. High labor intensity: Long-term visual inspection increases the labor intensity of workers, may cause visual fatigue, and further affect the accuracy and efficiency of detection. 4. Increased costs: Manual inspection is not only inefficient, but also with the increase in labor costs, relying heavily on manual inspection will significantly increase production costs. In view of this, overcoming the problems existing in the above-mentioned prior art is a problem to be solved in this technical field. Utility Model Content

[0026] The following will clearly and completely describe the concept, specific structure and technical effects of the utility model in combination with the embodiments and drawings, so as to fully understand the purpose, characteristics and effects of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of them. Based on the embodiments of the utility model, other embodiments obtained by technicians in this field without creative work are all within the scope of protection of the utility model. In addition, all the connection / connection relationships involved in the patent do not refer to the direct connection of components, but refer to the formation of a better connection structure by adding or reducing connection accessories according to the specific implementation situation. The various technical features in the creation of the utility model can be combined interchangeably without conflicting with each other.

[0027] Reference Figure 1 , Figure 2 The utility model provides a visual inspection structure for detecting defects in bandages, comprising: a feeding component 1 and a visual inspection component 2; the feeding component 1 is used to convey bandages, the visual inspection component 2 is arranged circumferentially along the running direction of the feeding component 1, and the visual inspection component 2 is used to detect defects in the bandages being conveyed. It can be understood that during the process of the bandage being conveyed by the feeding component 1 for secondary processing, the visual inspection component 2 is arranged circumferentially along the running direction of the feeding component 1, and the visual inspection component 2 is used to detect abnormalities on the bandages. The visual inspection structure of this scheme is easy to operate, has low production cost, high detection efficiency, reduces labor intensity, improves the safety and accuracy of operation, and greatly improves production efficiency and product quality.

[0028] In some embodiments, the feeding assembly 1 includes a feeding roller 11, a feeding rod 12 and a driving unit 13, wherein the driving unit 13 drives the feeding roller 11 to rotate, and the friction between the roller surface of the feeding roller 11 and the bandage drives the bandage to be transported through the feeding rod 12. Specifically, the bandage is sleeved on the feeding rod 12, and the feeding roller 11 rotates to drive the bandage to move along the feeding rod 12. In some embodiments, the diameter of the bandage in the actual state is smaller than the diameter of the feeding rod 12, so that when the bandage is sleeved on the feeding rod 12, the feeding rod 12 stretches the bandage, which is more conducive to the visual inspection assembly 2 to identify defects on the bandage.

[0029] Reference Figure 2 In some embodiments, the visual inspection component 2 includes a plurality of visual inspection units 21, and the plurality of visual inspection units 21 are arranged at intervals along the circumferential direction of the running direction of the feeding component 1, and the detection area of ​​the plurality of visual inspection units 21 can cover the area of ​​the bandage to be inspected. Since the bandage is sleeved on the feeding rod 12, it is equivalent to using the plurality of visual inspection units 21 to detect whether there is an abnormality in the bandage on the feeding rod 12, so the detection area of ​​a single visual inspection unit 21 is limited, and each visual inspection unit 21 detects a part of the bandage, and the cooperation of the plurality of visual inspection units 21 is required so that the detection area can cover the entire bandage, thereby quickly and accurately inspecting the bandage.

[0030] Reference Figure 2 , further, the number of the visual inspection units 21 is 3 and they are located on the circumference of the same plane, and the distance between any two of the visual inspection units 21 is the same. This is equivalent to that on a circular surface with the bandage as the center and perpendicular to the bandage, three visual inspection units 21 are arranged at equal intervals, and the angle between two adjacent visual inspection units 21 and the line connecting the bandage is 120°. That is to say, each of the visual inspection units 21 can cover one-third of the area of ​​the bandage, and setting up three visual inspection units 21 can just completely cover the entire bandage. Under the premise of not affecting the detection effect, the reasonable arrangement of the visual inspection units 21 helps to reduce the production cost of the equipment.

[0031] In some embodiments, the visual inspection unit 21 includes a mounting frame 211 and an imaging device 212 disposed on the mounting frame 211. The bandage is photographed by the imaging device 212, and the photographed photo is judged to determine whether the bandage has defects. The mounting frame 211 can be a single bracket or an integral bracket, such as a circular, triangular, quadrilateral, etc. shape, and the imaging device 212 is mounted on the mounting frame 211. The area photographed by the imaging device 212 can cover the entire bandage. Among them, the imaging device 212 can be a digital camera, a film camera, a single-lens reflex camera (DSLR), a lens interchangeable mirrorless camera (Mirrorless), etc., which can clearly take photos of the bandage. It can be selected according to the type of bandage to be detected, different detection standards, etc.

[0032] Reference Figure 2 , Figure 3 Further, the mounting frame 211 includes a mounting rod 2111 and an angle adjustment structure 2112, the visual inspection unit 21 is connected to the mounting rod 2111 via the angle adjustment structure 2112, and the angle between the visual inspection unit 21 and the mounting rod 2111 can be adjusted via the angle adjustment structure 2112. It is understandable that if there is an error in the angle of the visual inspection unit 21 toward the bandage, resulting in the visual inspection unit 21 failing to completely cover the surface of the bandage, the angle of the visual inspection unit 21 toward the bandage needs to be adjusted via the angle adjustment structure 2112.

[0033] Reference Figure 3 Specifically, the adjustment structure includes a first fixing plate 2112a and a second fixing plate 2112b that are arranged opposite to each other, an adjustment plate 2112c that is arranged between the first fixing plate 2112a and the second fixing plate 2112b, the imaging device 212 is arranged on the adjustment plate 2112c, and the first fixing plate 2112a, the second fixing plate 2112b are rotatably connected to the mounting rod 2111. During adjustment, the imaging device 212 can be adjusted to a suitable position by adjusting the angle between the first fixing plate 2112a, the second fixing plate 2112b and the mounting rod 2111, and then adjusting the angle of the adjustment plate 2112c relative to the mounting rod 2111.

[0034] Reference Figure 1 , Figure 2In some embodiments, the visual inspection unit 21 further includes a light source device 213, which is irradiated on the bandage to improve the brightness of the bandage. It is understandable that the light of the light source device 213 is irradiated on the bandage, and the bandage in the imaging device 212 has more light, so the imaging will be clearer, which can further improve the accuracy of the judgment and reduce misjudgment. Furthermore, the light source device 213 is in the shape of a long strip and parallel to the running direction of the feeding assembly 1 and is rotatably connected to the first fixing plate 2112a and the second fixing plate 2112b. In other words, the light source device 213 can provide a light source along the direction in which the bandage extends, so that the intensity of the reflected light on the entire bandage remains consistent, avoiding overexposure of one part and underexposure of another part, and improving the clarity of the imaging device 212.

[0035] In addition, the utility model also proposes a visual automatic detection device, which, compared with the visual detection structure, also includes a control component (not shown), and the control component is electrically connected to the feeding component 1 and the visual detection component 2. That is to say, the feeding component 1 and the visual detection component 2 are operated through the program preset by the control component, so that the entire process of feeding, transmitting, and detecting the bandage can be automatically completed. The control component can identify whether there are defects in the bandage in the photo taken by the visual detection component 2. Through the control component and mechanical structure design, the automation of the production process is realized, promoting the transformation of the entire industry to intelligent production.

[0036] The control component may select a programmable logic controller (PLC) as a control center to write programs to control the feeding and detection actions.

[0037] Reference Figure 1 In some embodiments, the visual automatic inspection device further includes a cutting component 3 and a blanking component, and the control component is electrically connected to the cutting component 3 and the blanking component, so that the bandage that passes the inspection is cut by the cutting component 3, and then collected by the blanking component. When the visual automatic inspection device detects that the bandage has a preset defect, the control component will control the entire device not to perform subsequent processing.

[0038] The above is a specific description of the preferred implementation of the utility model, but the invention of the utility model is not limited to the described embodiments. Technical personnel familiar with the field can also make various equivalent deformations or substitutions without violating the spirit of the utility model. These equivalent deformations or substitutions are all included in the scope defined by the claims of this application.
