[0035] Example 1: As shown in the attached Figures 1 to 10 figure:

[0036] The present invention provides a visual inspection device for clothing fabric defects, including a workbench 101 as the basic support of the entire device. On the top of the workbench 101, two groups of side plates 102 are symmetrically arranged. Between the two groups of side plates 102, a unwinding assembly for transporting the fabric 103 is installed. The unwinding assembly can stably unwind the fabric 103 from the discharging roller 107 and make it transmit along a predetermined path. On the top of the unwinding assembly, a defect inspection assembly is provided. The defect inspection assembly includes a visual inspection module 201 and an RFID tag 202. The visual inspection module 201 can be of the K210 model. The visual inspection module 201 is installed on the top of the fabric 103 and can detect defects of the fabric 103 during the transmission process. The RFID tag 202 is used to record the defect information of the fabric 103. On one side of the visual inspection module 201, a tag placement arm 203 is provided for pasting the RFID tag 202 recording the defect information near the corresponding defect area. In addition, a soft light 104 is also provided between the two groups of side plates 102. The soft light 104 is located below the fabric 103, and its function is to provide uniform and soft light for the visual inspection module 201 to ensure that the visual inspection module 201 can clearly obtain the image information of the fabric 103. A lifting assembly is provided on the periphery of the soft light 104, and two groups of stretching assemblies are symmetrically arranged on the two groups of side plates 102.

[0037] Please refer to such as Figure 2 , Figure 4 and Figure 6As shown in the figure, the tops of the two groups of side plates 102 are both connected to the installation top frame 106 through two groups of columns 105. The columns 105 play a role in support and connection, ensuring that the installation top frame 106 can be stably erected above the fabric 103.

A horizontal gyroscope 222 is provided on the lifting table assembly 221. The horizontal gyroscope 222 can be of the KR112 model. By using the horizontal gyroscope 222 to identify the levelness of the label placing arm 203, the accuracy of the operation of the label placing arm 203 is improved. During the detection process, the visual inspection module 201 detects defects and wrinkles on the fabric 103. When wrinkles are detected, the stretching component will be activated for operation. When defects are detected, the shooting module 220 will collect image information of the defective area of the fabric 103, and then input the image information into the RFID tag 202 on one side of the clamping through groove 213 through the RFID reader / writer 216. Finally, the label placing arm 203 pastes the RFID tag 202 near the defective area to achieve the recording and marking of defect information.

[0046] Embodiment 2: Based on the visual clothing fabric defect detection device provided in Embodiment 1 of the present application, Embodiment 2 of the present application proposes a visual clothing fabric defect detection device. This Embodiment 2 is only a preferred embodiment of Embodiment 1, and the implementation of Embodiment 2 will not affect the independent implementation of Embodiment 1. The second Embodiment 2 of the present invention will be further described below.

[0047] Please refer to Figure 11 and Figure 12As shown, the stretching assembly also includes a plurality of groups of toggle hubs 425. Two groups of third mounting plates 426 are respectively installed on the top of the movable frame 401 and the bottom of the lifting frame 415, providing a basis for the installation of the plurality of groups of toggle hubs 425. A plurality of rotating seats 427 are evenly arranged between the two groups of third mounting plates 426. Each rotating seat 427 is provided with a toggle hub 425 corresponding to the cloth 103. The toggle hub 425 can rotate on the rotating seat 427. When the cloth 103 is stretched, the toggle hub 425 can be in the process of continuous transportation of the cloth 103. The cloth 103 can be clamped in the process without stopping the transportation of the cloth 103, thereby improving the efficiency of the entire detection and processing process and avoiding the time waste caused by suspending the transportation; two groups of second guide holes 421 are provided at the bottom of the lifting frame 415, and two groups of second guide columns 422 are provided on the top of one group of third mounting plates 426. The two groups of second guide columns 422 are respectively slidably penetrated in the two groups of second guide holes 421, ensuring that the third mounting plate 426 can maintain a stable track when moving with the lifting frame 415, avoiding deviation or shaking, thereby The clamping operation of the toggle hub 425 on the cloth 103 is ensured to be more reliable. At the same time, a spring 424 is also arranged on the top of one of the third mounting plates 426, and a pressure sensor 423 is arranged on the bottom of the lifting frame 415. The top of the spring 424 contacts the pressure sensor 423. The pressure sensor 423 can monitor the pressure change of the spring 424 in real time, and then know the clamping force of the two sets of toggle plates 419, so as to avoid damage to the cloth 103 due to excessive clamping force, thereby ensuring the quality of the cloth 103. A fourth mounting seat 428 is provided at both ends, and photoelectric sensors 429 are provided on the two groups of fourth mounting seats 428 corresponding to the edge positions of the cloth 103. When the cloth 103 deviates during transportation, the photoelectric sensor 429 in the corresponding direction will be blocked by the cloth 103. At this time, the stretching component on the opposite side pushes out the movable frame 401, and the lifting motor 413 is started to make the multiple groups of toggle hubs 425 descend and clamp the cloth 103, and pull the deviated cloth 103 to the preset middle position, ensuring that the cloth 103 is always transported on the correct track.

[0048] Compared with the method of stretching the wrinkles only by the toggle plate 419 and the curved surface 420 in the first embodiment, the second embodiment respectively installs two sets of third mounting plates 426 on the top of the movable frame 401 and the bottom of the lifting frame 415, and evenly arranges multiple sets of rotating seats 427 between the two sets of third mounting plates 426, and each rotating seat 427 is provided with a toggle hub 425 corresponding to the cloth 103. The main difference is that the toggle plate 419 and the curved surface 420 in the first embodiment often need to suspend the transportation of the cloth 103 when stretching the cloth, which will undoubtedly interrupt the continuity of the entire detection process, not only consuming a lot of time, but also reducing production efficiency, while the toggle hub 425 in the second embodiment can be suspended when the cloth 1 03 is continuously transported, and the cloth 103 is clamped, thereby improving the overall efficiency of detection; in addition, in the second embodiment, a photoelectric sensor 429 is set at the edge of the cloth 103. When the cloth 103 deviates during transportation, the photoelectric sensor 429 in the corresponding direction will be blocked by the cloth 103, and the stretching component on the opposite side pushes out the movable frame 401, and at the same time, the lifting motor 413 is started to make the multiple groups of toggle hubs 425 descend to clamp the cloth 103, and the deviated cloth 103 is pulled to the preset middle position, ensuring that the cloth 103 is always transported along the correct track, avoiding the detection error caused by the deviation of the cloth 103; the remaining conditions are consistent with the first embodiment, so this embodiment will not be repeated.

[0049] The embodiments described above are only used to illustrate the technical solutions of the present invention, rather than to limit the same. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that the technical solutions described in the aforementioned embodiments may still be modified, or some of the technical features may be replaced by equivalents. Such modifications or replacements do not deviate the essence of the corresponding technical solutions from the spirit and scope of the technical solutions of the embodiments of the present invention, and should all be included in the protection scope of the present invention.
