[0049] See also Figures 1 to 5 This embodiment provides a fabric inspection device. This device is used to inspect fabric 300 for defects and affix labels 128 to the defects. This device is applicable to various types of fabric 300 inspections, improving inspection efficiency and ensuring the secure attachment of labels 128, preventing them from falling off the fabric 300.

[0050] like Figure 1As shown, in this embodiment, the fabric inspection device includes a visual inspection device 200 and a labeling device 100. The visual inspection device 200 is used to detect the presence of defects in the fabric 300 and the location of the defects. The labeling device 100 is used to affix a label 128 to the location of the detected defect (i.e., the defect), indicating the presence of the defect at that location. The fabric inspection device is located in front of the labeling device 100. The fabric 300 first passes through the visual inspection device 200 and then through the labeling device 100. The fabric inspection device detects the location of the defect on the fabric 300 and then controls the labeling device 100 to affix the label 128 to that location.

[0051] like Figure 1 As shown, the visual inspection device 200 includes a detection camera 201, which is used to detect defects on the fabric 300. The detection camera 201 is set above the fabric 300 and is used to take an image of the fabric 300. The collected image is detected and defects are identified through a visual recognition algorithm. Figure 1 As shown, in this embodiment, the visual inspection device 200 is provided with two inspection cameras 201, and the two inspection cameras 201 are arranged at intervals along the width direction of the fabric 300 (i.e., perpendicular to the transmission direction of the fabric 300), so that the shooting range of the inspection camera 201 can cover the entire width of the fabric 300 and ensure the clarity of the collected image.

[0052] like Figure 1 As shown, in this embodiment, the visual inspection device 200 further includes a hood 202, which is positioned above the fabric inspection area, and the inspection camera 201 is positioned within the hood 202. The fabric inspection area corresponds to the area corresponding to the image captured by the inspection camera 201. The hood 202 can be formed by splicing together multiple opaque panels, with a frame positioned within the panels. In other embodiments, the hood 202 can also be made of a flexible material such as canvas with good light-blocking properties. In this embodiment, positioning the hood 202 outside the inspection camera 201 ensures relatively stable light in the fabric inspection area, preventing changes in external light from affecting the inspection structure.

[0053] like Figure 2 、 Figure 3 、 Figure 4 and Figure 5As shown, in this embodiment, the labeling device 100 includes a labeling assembly 12 and a cloth guiding device. The labeling assembly 12 includes: a suction cup 125, a label pressing roller 124, a lifting device and a translation drive 121. The labeling assembly 12 is set on the labeling frame 11 and is located above the cloth guiding assembly. The labeling frame 11 is set on a horizontal track, so that the labeling assembly 12 can move horizontally along the width direction of the cloth 300, so that the label can be attached to any position on the width of the cloth. Figure 2 As shown, the cloth guide device is used to transport the cloth 300 so that the cloth 300 passes under the suction cup 125 and the label pressing roller 124. The cloth 300 output by the visual inspection device 200 is transported through the cloth guide device so that the cloth 300 is horizontally stretched and transported, thereby facilitating the affixing of the label 128 to the defective area on the cloth 300.

[0054] The lifting device includes: a lifting track 122, a lifting drive motor 1221 and the lifting seat 123; the lifting seat 123 is slidably arranged on the lifting track 122; the lifting drive motor 1221 is transmission-connected to the lifting seat 123 via a transmission belt.

[0055] The cloth guiding device includes a first cloth guide roller 22, a second cloth guide roller 23, and a cloth guide drive motor 21. The first and second cloth guide rollers 22, 23 are arranged parallel to each other, and the cloth guide drive motor 21 is used to drive the first and second cloth guide rollers 22, 23 to rotate. The cloth 300 is transported by the first and second cloth guide rollers 22 and stretched tautly by the first and second cloth guide rollers 22. In this embodiment, the cloth guide drive motor 21 is connected to both the first and second cloth guide rollers via a drive belt, causing them to rotate synchronously. In other embodiments, the cloth guide drive motor 21 may use other transmission methods, such as a gear train or chain, to simultaneously drive both the first and second cloth guide rollers.

[0056] like Figure 2 、 Figure 3 and Figure 4As shown, the lifting device is arranged on the translation drive member 121, and the lifting device includes a lifting seat 123, a lifting rail 122 and a lifting drive motor 1221; the pressure roller 124 and the suction cup 125 are arranged on the lifting seat 123, and along the transmission direction of the cloth 300, the suction cup 125 is located in front of the pressure roller 124. The translation drive member 121 is used to drive the suction cup 125 and the pressure roller 124 to move back and forth horizontally between the mark taking position and the pressure mark position. The translation drive member 121 can be a drive member that can perform linear reciprocating telescopic movement, such as an oil cylinder, an air cylinder, a linear motor or an electromagnetic push rod. Preferably, in this embodiment, the translation drive member 121 includes an air cylinder, which is arranged horizontally, and the lifting device is arranged at the end of the telescopic rod of the air cylinder.

[0057] The lifting device is used to drive the suction cup 125 and the label pressing roller 124 up and down, so that the suction cup 125 can absorb the label 128 at the label removal position and adhere the label 128 to the fabric 300 at the label application position, and the label pressing roller 124 can compress the label 128 adhered to the fabric 300. In this embodiment, the labeling assembly 12 also includes a vacuum generator 130, to which the suction cup 125 is connected via a pipe. The vacuum generator 130 provides the suction cup 125 with sufficient suction force to adhere the label 128. The operating principle of the vacuum generator is based on the ejection phenomenon and the Venturi effect in fluid mechanics. The vacuum generator is driven by compressed air. After high-pressure compressed air enters the vacuum generator, it passes through a carefully designed nozzle (typically with a convergent-divergent shape). During this process, the air flow rate increases dramatically, while the pressure decreases accordingly. This phenomenon is called "entrainment flow," where a low-pressure area forms around the nozzle outlet, which "entrains" surrounding air, thereby generating a vacuum.

[0058] like Figure 3 and Figure 5 As shown, when the label 128 is pasted, the translation drive member 121 is first retracted to drive the suction cup 125 and the label pressing roller 124 to move to the label suction position (i.e., to the label suction position). Figure 3 and Figure 5 The left side of the movement), and then the lifting device drives the suction cup 125 and the pressure roller 124 to descend, so that the suction cup 125 absorbs the label 128; then the lifting device moves up to a certain height, and the translation drive member 121 extends forward to the labeling position (i.e. Figure 3 and Figure 5The lifting device drives the suction cup 125 and the label pressing roller 124 to descend, so that the label 128 is attached to the fabric 300. After the label 128 is attached to the fabric 300, the label 128 is transported along with the fabric 300 through the label pressing roller 124, and is thus firmly pressed and attached to the fabric 300 by the label pressing roller 124.

[0059] In this embodiment, a suction cup 125 and a pressure roller 124 are provided in the labeling device 100 of the fabric inspection device, wherein the suction cup 125 is located in front of the pressure roller 124 along the conveying direction of the fabric. After the suction cup 125 adheres the label 128 to the fabric 300, the label 128 is conveyed through the pressure roller 124 along with the fabric 300, so that the label 128 is firmly pressed onto the fabric 300 by the pressure roller 124, thereby improving the adhesion strength between the label 128 and the fabric and preventing the label 128 from falling off the fabric 300.

[0060] like Figure 3 As shown, in this embodiment, the labeling device 100 also includes a receiving roller 126 and a label suction platform 129; the receiving roller 126 is connected to a drive motor, which is used to drive the transmission of the entire bundle of labels 128 and allow the labels 128 to pass through the label suction platform 129 one by one; the label suction platform 129 is located below the label removal position and is used to support the label 128 when removing the label from under the suction cup 125.

[0061] The labels 128 are bundled together on the labeling assembly. The bundle consists of a base paper and individual labels 128 with adhesive backing affixed to the base paper. The base paper is secured to a delivery roller 126, which rotates and drives each label 128 across a label suction platform 129. The suction cup 125 on the platform moves downward, removing the label 128 from the base paper. The delivery roller 126 is connected to a drive motor that rotates the delivery roller 126. The delivery roller collects the base paper, not the labels 128 themselves.

[0062] In this embodiment, a label suction platform is provided so that when the suction cup 125 moves downward to absorb the label 128, the label suction platform 129 can support the label 128, so that the suction cup 125 can reliably absorb the label 128, thereby peeling the label 128 off the backing paper.

[0063] In this embodiment, a sensor 127 is disposed above the label suction platform 129. The sensor 127 is used to detect whether the label 128 has been transferred to the label suction platform 129. The sensor may be a photoelectric sensor or a Hall effect sensor. The sensor can detect whether a label 128 has been transferred to the label suction platform 129, thereby confirming that the suction cup 125 can always attract the label 128.

[0064] like Figure 3 and Figure 5 As shown, in this embodiment, the marking roller 124 includes a roller 1242 and a compression spring 1241. The roller 1242 is connected to the bottom end of the compression spring 1241. The compression spring 1241 is used to provide elastic downward pressure to the roller 1242 when the roller 1242 contacts the fabric 300. The roller 1242 is mounted on a roller 1242 bracket, which is connected to the bottom end of the compression spring 1241. The top end of the compression spring 1241 is fixedly mounted. When the lifting device drives the suction cup 125 and the pressure roller 124 to descend for labeling, the pressure roller 124 and the suction cup 125 are in contact with the fabric 300, and the compression spring 1241 is in a compressed state. When the lifting device moves up a certain distance to make the suction cup 125 leave the fabric 300, the compression spring 1241 rebounds to a corresponding length, but the compression spring 1241 is still in a compressed state, so that when the suction cup 125 leaves the fabric 300, the pressure roller 124 can still press the fabric 300, so that when the suction cup 125 leaves the fabric 300, the label 128 can be effectively pressed onto the fabric 300.

[0065] Finally, it should be noted that although the above embodiments have been described in the specification and drawings of this application, this does not limit the scope of patent protection of this application. All technical solutions generated by replacing or modifying equivalent structures or equivalent processes based on the essential concepts of this application using the contents recorded in the specification and drawings of this application, as well as directly or indirectly implementing the technical solutions of the above embodiments in other related technical fields, are included in the scope of patent protection of this application.
