[0038] The yarn detecting device and the yarn processing equipment according to the embodiments of the present application will be described below with reference to the accompanying drawings.
[0039] Reference Figures 2 to 6 According to the yarn detection device 10 of the embodiment of the utility model, it includes a background plate 100, a mobile component 200 and a visual camera 300. The background plate 100 has a reflection surface 130, and the reflection surface 130 is used to face the yarn 30. The reflection surface 130 is provided with a first color area 110 and a second color area 120. The mobile component 200 can move relative to the background plate 100. The visual camera 300 is connected to the mobile component 200 to capture the yarn image at each background plate 100. The background plate 100 is provided with a first color area 110 and a second color area 120. The first color area 110 is used to fill the color with a sharp contrast with the yarn 30, so as to improve the contrast between the yarn 30 and the background in the image captured by the visual camera 300, so that the characteristics of the yarn 30 are more easily extracted by the visual camera 300, and the detection difficulty is reduced. The second color area 120 is used to fill the color for the visual camera 300 to recognize, so that the visual camera 300 can make a bad judgment on the yarn 30 while capturing an image with a complete second color area 120, so as to ensure the bad judgment of the yarn 30 at the corresponding position and improve the detection accuracy.
[0040] Specifically, the mobile component 200 can be selected as a conventional mobile component 200 in the art, such as a linear drive, an AGV mobile device, a transport robot, etc. A track can also be set on the ground to provide guidance for the movement of the mobile component 200 and reduce the control difficulty of the mobile component 200. The visual camera 300 can be selected as a conventional visual camera 300 in the art. The visual camera 300 is correspondingly connected to a conventional image processing system in the art. The gray value feature operation of the pixel points in the image captured by the visual camera 300 by the image processing system can be used to judge the yarn 30 such as breakage, fuzzing, wear, and separation from the guide member. The specific judgment method can be learned from the relevant literature in the art, and this application will not be described in detail. Among them, the first color area 110 and the second color area 120 can be selected as the same color or different colors, and can be adaptively changed according to the color of the yarn 30 and the recognition setting of the visual camera 300.
[0041] Reference Figure 4 and Figure 5 In some embodiments, the first color area 110 and the second color area 120 are arranged at intervals along the first direction, and the first color area 110 and the second color area 120 extend along the second direction by a set length, and a plurality of background plates 100 are arranged at intervals along the second direction, and the visual camera 300 can move relative to the background plate 100 along the second direction, and the second direction is perpendicular to the first direction. The first color area 110 and the second color area 120 are arranged at intervals along the first direction, and the first color area 110 and the second color area 120 extend along the second direction, so that the first color area 110 and the second color area 120 can use the space in the first direction to be located in the capture area 310 of the visual camera 300 at the same time, so as to ensure that the first color area 110 and the second color area 120 correctly play their respective roles. And the visual camera 300 moves relative to the background plate 100 along the second direction, so as to realize the detection of the yarn 30 reflected by each background plate 100 one by one.
[0042] Reference Figure 5 Further, the visual camera 300 has a set shooting interval time T, the moving component 200 has a set movement speed V, the visual camera 300 has a set shooting length L1, and the first color area 110 and the second color area 120 have a set extension length L2 in the second direction, satisfying: TV≤L1-L2, L1≥L2. Among them, the restriction of L1≥L2 can ensure that the capture area 310 of the visual camera 300 can accommodate the first color area 110 and the second color area 120. The restriction of TV≤L1-L2 can ensure that the distance TV moved by the moving component 200 in one shooting interval is less than the difference between the shooting length K1 of the capture area 310 in the second direction and the extension length L2 of the first color area 110 and the second color area 120 in the second direction, so as to ensure that the visual camera 300 can capture the complete first color area 110 and the second color area 120, and ensure the accurate detection.
[0043] Reference Figure 5 As another improvement of the above solution, the visual camera 300 has a set shooting length L1, and the first color area 110 and the second color area 120 have a set extension length L2 in the second direction, satisfying: L2≤L1<2L2. Among them, the restriction of L1<2L2 can ensure that during the shooting process of the visual camera 300, only the first color area 110 and the second color area 120 on one background plate 100 can be located in the capture area 310 at the same time, so as to ensure the detection of the yarn 30 reflected by each background plate 100 one by one.
[0044] Reference Figure 6 and Figure 7In some embodiments, the yarn detection device 10 further includes a light source 400, which is connected to the moving assembly 200 and can emit light toward the background plate 100. By providing the light source 400, the brightness can be increased when the visual camera 300 captures an image, so as to improve the clarity of the captured image and the detection accuracy.
[0045] Further, refer to Figure 6 The yarn detection device 10 further includes an adjustment component 210, and the light source 400 is connected to the adjustment component 210. The adjustment component 210 can drive the light source 400 to move around the axis.

Specifically, the adjustment component 210 includes a rotating shaft extending along the second direction, and the light source 400 is connected to the radial surface of the rotating shaft to realize the movement of the light source 400 around the second direction. In some embodiments, the adjustment component 210 may include a first rotating shaft extending along the second direction, a second rotating shaft extending along the fourth direction, and a third rotating shaft extending along the third direction. The first rotating shaft, the second rotating shaft and the third rotating shaft are connected in sequence, and the light source 400 is connected to the outer surface of the first rotating shaft, thereby realizing the three-axis adjustment of the light source 400.
[0046] In some embodiments, the visual camera 300 is connected to the adjustment component 210 so as to drive the visual camera 300 to move around the axis through the adjustment component 210 to adjust the capture picture of the visual camera 300, ensuring that the capture area 310 can cover the first color area 110 and the second color area 120 of the background plate 100, thereby ensuring the capture of the image of the yarn 30.
[0047] The visual camera 300 and the light source 400 can be connected to the same adjustment component 210. For example, in some embodiments, the visual camera 300 and the light source 400 are connected to the same rotating shaft extending in the second direction, or, in other embodiments, the visual camera 300 and the light source 400 are connected to the outer surface of the same first rotating shaft. In other embodiments, the adjustment component 210 includes a first adjustment member 211 and a second adjustment member 212, and the visual camera 300 and the light source 400 are respectively connected to the first adjustment member 211 and the second adjustment member 212 to achieve the respective adjustment of the visual camera 300 and the light source 400. The first adjustment member 211 and the second adjustment member 212 can both be rotating shafts extending in the second direction, or can be a mechanism formed by connecting the first rotating shaft, the second rotating shaft and the third rotating shaft.
[0048] Reference Figures 1 to 5According to the embodiment of the utility model, the yarn 30 processing device comprises a yarn detection device 10 of any of the above embodiments and a plurality of yarn processing devices 20, wherein the yarn processing device 20 can convey the yarn 30 along a set direction, and the plurality of yarn processing devices 20 are arranged along a second direction. A plurality of background plates 100 are connected to each yarn processing device 20 one by one, the first color area 110 and the second color area 120 are arranged at intervals along a first direction, the first direction is perpendicular to the second direction, one side of the reflection surface 130 of the background plate 100 is used to set the yarn 30, and the moving component 200 can move relative to the yarn processing device 20 along the second direction. By applying the yarn detection device 10 of the embodiment of the present application, the difficulty of detecting the yarn 30 processed by each yarn processing device 20 can be reduced, and the detection accuracy can be improved.
[0049] Specifically, the yarn processing device 20 can be selected as a conventional doubling, false twisting or re-twisting device in the art. The yarn processing device 20 includes a fixed frame 500, and the fixed frame 500 is used to install the yarn processing device 20. In some embodiments, the fixed frame 500 is provided with yarn processing devices 20 on both sides in the third direction to improve space utilization, increase the number of yarn processing devices 20, and enable the moving assembly 200 to detect the yarn 30 processed by each yarn processing device 20 when moving on both sides of the fixed frame 500 in the third direction, thereby improving the utilization of the yarn detection device 10.
[0050] Reference Figure 1 and Figure 2 Further, the yarn detection device 10 includes a plurality of fixed frames 500, each of which is arranged at intervals along the third direction to further increase the number of yarn processing devices 20. The moving component 200 can be provided with visual cameras 300 and light sources 400 on both sides in the third direction, respectively, so that when the moving component 200 is located between adjacent fixed frames 500, the yarn 30 processed by the yarn processing devices 20 on the two fixed frames 500 can be detected at the same time to further improve the detection effect. On the same fixed frame 500, the fixed frame 500 can be provided with multiple groups of yarn processing devices 20 in the fourth direction, and the moving component 200 can also be provided with multiple groups of visual cameras 300 and light sources 400 in the fourth direction to further improve the production and detection efficiency.
[0051] Reference Figures 2 to 4As another improvement of the above scheme, in some embodiments, the yarn processing device 20 includes a winding roller 600 and a roller 700, the winding roller 600 is used to drive the yarn 30 to move, the roller 700 is used to wind the yarn 30, the winding roller 600 and the roller 700 can both rotate around the second direction, and the winding roller 600 and the roller 700 are sequentially arranged in the fourth direction. The yarn detection device 10 also includes a lifting component 220, the lifting component 220 is connected to the moving component 200, the lifting component 220 can move in the fourth direction relative to the moving component 200, and the lifting component 220 can abut against at least a part of the roller 700 to drive the roller 700 to drive the yarn 30 to separate from the winding roller 600. Through the lifting component 220 abutting against the roller 700, the yarn processing device 20 can be shut down. When the visual camera 300 captures a defective yarn 30, the lifting assembly 220 operates to lift the roller 700, so that the yarn 30 is separated from the winding roller 600 under the support of the roller 700, and the winding operation is stopped, so that the staff can handle the defective yarn in time. The movement of the lifting assembly 220 relative to the moving assembly 200 can be achieved by a driver such as a linear module or a driving rod installed on the moving assembly 200.
[0052] Specifically, the roller 700 includes a main body 710 and a supporting arm 720 connected to each other, the supporting arm 720 is rotatably connected to the fixed frame 500, the supporting arm 720 is connected to one side of the axial direction of the main body 710, the supporting arm 720 can drive the main body 710 to move relative to the fixed frame 500, and the supporting arm 720 extends along the third direction. Through the setting of the supporting arm 720, the supporting of the lifting assembly 220 and the roller 700 can be facilitated to reduce the difficulty of lifting the roller 700. Among them, after the roller 700 is lifted, the lifting assembly 220 can be used to keep the lifting to avoid the yarn 30 returning to the winding roller 600. Alternatively, the roller 700 can be temporarily fixed after being lifted to a certain height by providing a conventional fixed structure such as a damping mechanism and a clamping mechanism, waiting for the staff to perform bad treatment. It is understandable that the main body 710 is rotatably connected to the fixing frame 500, wherein the main body 710 can be directly connected to the fixing frame 500, and the lifting movement of the main body 710 can be realized by providing a groove extending along the fourth direction on the fixing frame 500.
