Description

Technical Field

[0001] The present application relates to the technical field of yarn detection, and in particular to a yarn tension detection system. Background Art

[0002] In the textile industry, yarn tension control is a key factor in ensuring product quality. With advances in automation technology, traditional yarn tension detection methods have been gradually replaced by electronic sensors. The application of this automated detection technology can effectively improve production inspection efficiency.

[0003] At present, the yarn tension detection system specifically includes a yarn fixing component, a tension sensor, a controller and a display screen; the tension sensor and the display screen are both electrically connected to the controller; during the actual detection process, the detection personnel pre-fix and tension the two ends of several yarns through the yarn fixing component, and then press the surface of the aforementioned yarns in turn through the tension sensor to detect the surface tension value of the yarn, and then the controller obtains the tension values ​​of all yarns detected by the tension sensor and displays them on the display screen in the form of a curve graph, so that the detection personnel can intuitively know the tension values ​​of all the aforementioned yarns.

[0004] Regarding the above-mentioned related technologies, in the process of tensioning and fixing the yarn, especially when tensioning multiple relatively fine yarns, it is easy for more than one yarn to be entangled with each other due to human operational errors or other reasons. This situation can easily further lead to inaccurate tension values ​​being detected, affecting the detection yield rate, so it needs to be improved. Summary of the Invention

[0005] In order to improve the accuracy of yarn tension detection, the present application provides a yarn tension detection system.

[0006] The present application provides a yarn tension detection system, comprising a detection platform and a tension detector disposed on the detection platform, the tension detector being electrically connected to a controller, the controller being electrically connected to a detection result output module, and the detection platform being further provided with a tensioning assembly for tensioning and fixing a yarn detection portion to a preset detection area on the detection platform; the system is characterized in that: the tension detector is used to detect a yarn tension value within the preset detection area, the controller is used to obtain the yarn tension value and control the detection result output module to output the yarn tension value for information to a detection personnel; The controller is also electrically connected to a visual detection module, which is used to obtain the yarn image in the preset detection area; the controller is used to obtain the yarn image and analyze whether there is any abnormality, and is used to issue a warning message for the inspection personnel to know through the detection result output module when an abnormality exists; wherein the abnormality includes at least yarn entanglement.

[0007] By adopting the above technical solution, a visual inspection module is added to capture the yarn image in the preset inspection area, and a controller is used to analyze the yarn image and determine whether there are any abnormal conditions (such as yarn entanglement). In this way, abnormal problems can be avoided in advance before tension detection, thereby improving inspection efficiency and reducing the defective product rate.

[0008] Preferably, the detection platform is also provided with a moving part, which is used to drive the tension detector to move into or out of the preset detection area and enable the tension detector to detect the yarn tension value of the yarn in the preset detection area when it moves into the preset detection area; the controller is controlled by the moving part, and the controller is also used to control the moving part to start the tension detector to detect and obtain the yarn tension value of the yarn at the corresponding position when driving the tension detector to move to each yarn based on the position of each yarn in the yarn image.

[0009] By adopting the above-mentioned technical solution, the present application further provides the use of a controller in combination with a yarn image to analyze the position of each yarn in a preset detection area, and determines the starting time of the tension detector based on the position and the moving position of the tension detector to ensure that the tension detector is automatically started when it moves to the position of each yarn, that is, the yarn image detected by the visual detection module is used as the starting condition of the tension detector, thereby further improving the level of detection automation.

[0010] Preferably, the tensioning assembly includes a locking member provided on one side of the detection platform, and a yarn bobbin fixing member provided on the other side of the detection platform; the locking member is used to be fixedly connected to the free end of the yarn, and the yarn bobbin fixing member is used to fix the yarn bobbin and fix the release and winding of the yarn bobbin; the detection platform is also provided with a combing plate, the combing plate is provided with a plurality of comb teeth, and a combing hole for inserting a single yarn is reserved between adjacent comb teeth; It also includes a first loosening member, a lifting member and a sliding member; the loosening member is used to drive each of the yarn bobbin fixing members to move towards or away from each other; the lifting member is used to drive the combing plate to rise and fall, so that the yarn can be inserted into the combing hole during the rising process of the combing plate, and the yarn can be separated from the combing hole during the descending process of the combing plate; the sliding member is used to drive the combing plate to slide back and forth between the yarn bobbin fixing member and the detection platform.

[0011] By adopting the above technical solution, the sparse component is used to drive all the yarn tubes to move away from each other, so as to realize the evacuation and separation of the yarns, and then the lifting component is used to drive the combing plate to rise so that the separated yarns can be inserted into one of the combing holes, and then the moving component is used to drive the combing plate to slide in the direction close to the detection table, so as to utilize the limiting effect of the combing plate to evacuate and separate the yarns in the preset detection area, and finally the sparse component is used to drive the yarn tubes to approach each other and reset, so as to utilize the mutual coordinated movement of the combing plate and the yarn tube to realize the dispersion of the yarns and reduce the probability of yarn entanglement.

[0012] Preferably, the detection result output module includes a plurality of warning lights, one warning light corresponding to each combing hole, and the warning lights are arranged on the side wall of the combing plate near the corresponding combing hole; the controller is also used to control the warning light at the combing hole where the abnormal yarn is inserted to start after obtaining the yarn tension value detected by the tension detector; wherein, the abnormal yarn is a yarn whose yarn tension value is dissatisfied with the preset tension standard range.

[0013] By adopting the above technical solution, when abnormal yarn with substandard tension is found, the present application further proposes to set a warning light and control the on and off of the warning light to realize automatic positioning of the abnormal yarn. Compared with the positioning method of abnormal yarn by detection personnel themselves, the above method of the present application is more efficient and accurate.

[0014] Preferably, the driving end of the lifting member is connected to a lifting support plate, the combing plate is connected to the lifting support plate, and the number of the combing plates is 2, a magnetic member is provided between the two combing plates, one of the combing plates is connected to a sliding member, and the other combing plate is magnetically fixed to the combing plate through the magnetic member; the sliding member is used to drive the combing plate to slide back and forth on the lifting support plate toward or away from the detection platform; A limit baffle is provided on the side wall of the detection platform. When the combing plate close to the yarn bobbin fixing part moves to the limit baffle, it stops moving due to the blockage. The other combing plate continues to move to the specified position driven by the sliding part, so that the two combing plates are separated, and the preset detection area is formed between the two combing plates.

[0015] By adopting the above technical solution, the number of combing plates is limited to 2, and the two combing plates are moved to the detection table position by a sliding member and then separated, thereby forming a preset detection area to further reduce the probability of yarn entanglement in the preset detection area, thereby ensuring the accuracy of subsequent tension detection.

[0016] Preferably, the first loosening member includes a linkage support plate, a lifting frame, a wedge block, a support spring, and a return spring; the lifting frame is connected to one side of the detection platform through a support spring, and an insertion space for the wedge block is provided between adjacent yarn bobbin fixings, each insertion space corresponds to a wedge block and a return spring, and the return spring is connected to the yarn bobbin fixing corresponding to the corresponding insertion space, all the wedge blocks are connected to the lifting frame, and when the lifting frame is lifted or lowered, the wedge blocks are sequentially inserted into the corresponding insertion spaces in a preset order and the size of the corresponding insertion spaces is adjusted; one end of the linkage support plate is connected to the combing plate, and when the support spring is not deformed, the lifting frame is located on the lifting path of the other end of the linkage support plate.

[0017] By adopting the above technical solution, in the process of using the lifting member to drive the combing plate to move up, the lifting frame will move up under the action of the linkage bracket so that the wedge block is inserted into the insertion space, thereby causing the yarn bobbin fixing members to move in a direction away from each other, thereby realizing the evacuation and separation of the yarn. At this time, the support spring and the return spring are both in a deformed state. When the combing plate moves in a direction away from the yarn bobbin fixing member driven by the sliding member, the linkage support plate moves with the combing plate and breaks away from contact with the lifting frame, thereby causing the lifting frame and the wedge block to move down and reset under the elastic force of the support spring, and causing all the yarn bobbin fixing members to move and reset in a direction close to each other under the elastic force of the return spring.

[0018] Preferably, several groups of clamping members are provided on the combing plate, each group of clamping members includes two comb teeth, and a second loosening member is also provided on the combing plate, and the second loosening member is used to drive each group of clamping members to clamp the yarn in the corresponding combing hole; the side walls of the two comb teeth of each group of clamping members facing each other are provided with a sliding rod, and the yarn located in the combing hole is in contact with the sliding rod.

[0019] By adopting the above technical solution, after the yarn is inserted into the corresponding comb hole, the second combing member is used to further drive the two comb teeth to move toward each other and clamp the yarn, and the sliding rod is in direct contact with the yarn to limit the yarn while protecting the yarn.

[0020] Preferably, all the comb teeth contained in the clamping members are slidably connected to the combing plate; the second combing member includes a driving motor and a plurality of bidirectional screw rods, and the bidirectional screw rods are arranged in a one-to-one correspondence with the clamping members. The two comb teeth contained in each group of clamping members are respectively threadedly connected to the two ends of the corresponding bidirectional screw rods, and all the bidirectional screw rods are connected at the ends along the length direction and rotatably connected to the combing plate. The driving shaft of the driving motor is connected to the end of the bidirectional screw rod at the end to drive all the bidirectional screw rods to rotate.

[0021] By adopting the above technical solution, all the bidirectional screw rods are driven to rotate by starting the driving motor, so that the clamping member on each bidirectional screw rod moves and clamps the yarn in the corresponding combing hole.

[0022] Preferably, one of the comb tooth side walls included in each group of the clamping members is also provided with a cover plate, and the cover plate is rotatably connected to the corresponding comb tooth side wall through a torsion spring, and the corresponding comb tooth is also slidably connected to a push rod inside through a spring, and the surface of the comb plate is provided with a protrusion, and the push rod is used to contact the protrusion and be pushed by the protrusion in the process of sliding along the length direction of the bidirectional screw rod with the corresponding comb tooth, and slide and push the cover plate in the direction close to the corresponding cover plate, so that the cover plate is pushed by the push rod and rotates to cover the corresponding comb thread hole.

[0023] By adopting the above technical solution, during the process of the clamping member clamping the yarn, each clamping member is further provided with a cover plate that can rotatably cover the combing hole to further achieve the limitation of the yarn.

[0024] Preferably, the detection platform is further provided with a blowing member near the preset detection area for blowing the yarn surface in the preset detection area.

[0025] By adopting the above technical solution, the yarn surface in the preset detection area is blown by the blowing component to achieve the cleaning of the yarn, ensure the clarity of the yarn image subsequently captured by the visual detection module, and improve the accuracy of the controller's analysis and judgment of the yarn image.

By adding a visual inspection module to capture yarn images within the preset inspection area, the controller analyzes the yarn images and determines whether there are any abnormalities (such as yarn entanglement). This can prevent abnormalities before tension testing, thereby improving inspection efficiency and reducing defective product rates. 2. The present application further provides the use of a controller in combination with a yarn image to analyze the position of each yarn in a preset detection area, and determines the starting time of the tension detector based on the position and the moving position of the tension detector to ensure that the tension detector is automatically started when it moves to the position of each yarn, that is, the yarn image detected by the visual inspection module is used as the starting condition of the tension detector, thereby further improving the level of detection automation.

[0034] The following is combined with Figure 1-7 This application is described in further detail.

[0035] Example 1 Example 1 of the present application discloses a yarn tension detection system. Figure 1 、 Figure 2 and Figure 3The yarn tension detection system includes a detection platform 1, on which a tension detector 21 and a moving part 11 are provided. The moving part 11 is used to drive the tension detector 21 to slide back and forth along the length direction of the detection platform 1. The moving part 11 can specifically be a motor-screw combination structure or a pneumatic slide. A preset detection area is provided on the detection platform 1 and below the moving path of the tension detector 21. The detection platform 1 is also provided with a tensioning assembly 3 near the preset detection area. The tensioning assembly 3 is used to tension the two ends of the yarn and make the tensioned yarn located within the preset detection area. When the tension detector 21 moves above the preset detection area, it can conflict with the yarn in the preset detection area, thereby detecting the tension value of the yarn. Correspondingly, it also includes a controller 2, a visual detection module 22 and a detection result output module 23, and the moving part 11, the visual detection module 22, the tension detector 21 and the detection result output module 23 are all electrically connected to the controller 2.

[0036] Reference Figure 1 、 Figure 2 and Figure 3 , wherein the visual inspection module 22 is specifically a camera for capturing yarn images within a preset inspection area. The controller 2 is specifically a PLC controller, which is used to obtain the yarn image and, based on pre-stored reference images corresponding to each preset abnormality, compare and determine whether any reference image exists in the yarn image. If so, it indicates that the abnormality corresponding to the reference image exists. At this time, the controller 2 will mark the location of the abnormality in the aforementioned yarn image and then send the yarn image as a warning message to the detection result output module 23. Correspondingly, the detection result output module 23 includes a display screen 231 pre-connected to the controller 2 so that the detection result output module 23 can display the yarn image with the selection mark.

[0037] In addition, the controller 2 is also used to determine the position of the yarn in the preset detection area of ​​the detection platform 1 by analyzing the position of each yarn in the yarn image, that is, the distance between each yarn and the tension detector 21, and according to the current position of the tension detector 21 (the default initial position of the tension detector 21 is fixed), control the moving part 11 to drive the tension detector 21 to move toward the direction close to the preset detection area, and whenever the distance value to any yarn is 0, control the tension detector 21 to start, thereby realizing the automatic opening and closing of the tension detector 21.

[0038] Reference Figure 1The detection platform 1 is provided with a combing plate 4 along its length, and the combing plate 4 is provided with combing holes for yarn to pass through along its length; the tensioning assembly 3 includes a locking member 31 arranged on one side of the detection platform 1, and a yarn bobbin fixing member 32 arranged on the other side of the detection platform 1. The locking member 31 specifically includes a yarn roller for winding yarn, and a motor connected to the end of the yarn roller and driving the yarn roller to rotate. The yarn bobbin fixing member 32 is arranged in a one-to-one correspondence with the yarn bobbin, and the yarn bobbin fixing member 32 specifically includes a support frame 321 and a yarn bobbin mounted on the support. The yarn bobbin is wound with yarn, and the free end of the yarn on the yarn bobbin sequentially passes through the preset collection hole 331 on the preset collection plate 33, and then passes through the combing hole on the combing plate 4 and is wound around the yarn roller.

[0039] The implementation principle of a yarn tension detection system disclosed in Example 1 of the present application is as follows: the yarn bobbin is manually fixed on the support frame 321, and the free end of the yarn corresponding to each yarn bobbin passes through the combing plate 4 on the detection platform 1 and is then wrapped around the locking member 31 to achieve tensioning and fixation; and at this time, the yarn is located below the sliding path of the tension detector 21 when it slides along the length direction of the detection platform 1, so that the tension detector can contact the yarn during the sliding process to achieve tension detection.

[0040] The visual inspection module 22 captures the image of the yarn in the preset inspection area, and analyzes and determines whether there are any abnormal conditions (such as yarn entanglement, yarn breakage and frizziness, etc.). If so, a warning message is issued, and the aforementioned abnormal conditions are then manually assisted to resolve the aforementioned abnormal conditions. Finally, the moving part 11 is controlled to drive the tension detector 21 to move to each yarn to detect and obtain the yarn tension value. The controller 2 is used to obtain the yarn tension values ​​corresponding to the detection of all yarns, and connect the yarn tension values ​​of all the aforementioned yarns in the detection order to form a waveform diagram, which is displayed through the detection result output module 23. At the same time, the controller 2 is also used to compare each yarn tension value with the preset tension standard range, and determine the yarn corresponding to the yarn tension value that is not within the preset tension standard range as an abnormal yarn, and determine the position of the abnormal yarn based on the yarn image, and then control the corresponding warning light 232 to light up, so as to help the inspection personnel efficiently locate the abnormal yarn.

[0041] Example 2 The difference between Example 2 of the present application and Example 1 is that: Figure 2 and Figure 4 The end of the tension detector 21 is also connected to a purge member 12, which can specifically be a hair dryer. The purge member 12 and the tension detector 21 are driven by the moving member 11 to slide back and forth along the length direction of the detection platform 1, and the purge member 12 moves to the preset detection area before the tension detector 21 during the sliding process. The purge member 12 is used to transport air toward the preset detection area when moving to the preset detection area, so as to blow and clean the yarn surface in the preset detection area.

[0042] Reference Figure 4 and Figure 5 The locking member 31 specifically includes a locking ring 31 provided on the testing platform 1. Each yarn bobbin corresponds to a yarn, one end of which is wound around the yarn bobbin and the other end is fixedly tied to the locking ring 31. The yarn bobbin fixing member 32 includes a support frame 321 and a pressure plate 322 threadedly connected to the support frame 321. The yarn bobbin is hollow and sleeved on the support frame 321, and both ends of the yarn bobbin abut against the end wall of the support frame 321. The pressure plate 322 is threadedly connected to the support frame 321 and presses against the surface of the yarn bobbin to cooperate with the end wall of the support frame 321 to prevent the yarn bobbin from rotating.

[0043] Reference Figure 4 、 Figure 6 and Figure 7 The combing plate 4 is located between the yarn bobbin fixing member 32 and the detection platform 1 to evacuate and separate the yarn after being tensioned by the tensioning assembly 3, reducing the possibility of multiple yarns being entangled. Specifically, there are two combing plates 4, each of which includes several groups of clamping members 41 and a second loosening member 42 for driving the clamping members 41 to clamp the yarn. Each clamping member 41 includes two comb teeth 411. A combing hole 43 for inserting yarn is formed between the two comb teeth 411 of each clamping member 41. The side walls of the two comb teeth 411 of each clamping member 41 facing each other are also rotatably connected to a sliding rod 44. The second combing member 42 includes a drive motor 422 and a plurality of bidirectional screw rods 421. The bidirectional screw rods 421 are arranged in a one-to-one correspondence with the clamping member 41. The two comb teeth 411 contained in each clamping member 41 are respectively threadedly sleeved on the two ends of the corresponding bidirectional screw rod 421, so that when the bidirectional screw rod 421 rotates, the two comb teeth 411 can move toward or away from each other. The bidirectional screw rods 421 are rotatably connected to the combing plate 4, and all the bidirectional screw rods 421 are arranged in sequence along the length direction of the combing plate 4 and connected at the end. The drive motor 422 is connected to the corresponding combing plate 4, and the drive shaft of the drive motor 422 is connected to the end wall of the bidirectional screw rod 421 at the end to drive all the bidirectional screw rods 421 to rotate together.

[0044] Reference Figure 4 、 Figure 6 and Figure 7The side wall of one of the two comb teeth 411 included in each group of clamping members 41 is also rotatably connected to a cover plate 45 through a torsion spring, and the comb tooth 411 with the cover plate 45 is also slidably connected to a push rod 46 inside the combing plate 41 through a spring. A number of protrusions 47 are also provided on the surface of the combing plate 4 along its length direction. When the spring connected to the push rod 46 is not deformed, the protrusion 47 is located on the sliding path of the push rod 46 when it slides along the length direction parallel to the bidirectional screw rod 421 with the comb teeth 411; when the push rod 46 contacts the protrusion 47 with the movement of the comb teeth 411, the push rod 46 will be pushed by the protrusion 47 and slide toward the direction close to the cover plate 45 and push the cover plate 45, so that the cover plate 45 rotates to cover the combing hole 43.

[0045] Reference Figure 2 and Figure 6 In addition, the detection result output module 23 also includes a warning light 232 corresponding to the comb teeth 411 holes one by one. The warning light 232 is installed on the side wall of the combing plate 4 near the corresponding comb teeth 411 hole (not shown in the figure). The controller 2 is used to control the warning light 232 at the combing hole 43 where the abnormal yarn is inserted to start after obtaining the yarn tension value detected by the tension detector 21; wherein, the abnormal yarn is a yarn whose yarn tension value is not satisfied with the preset tension standard range.

[0046] Reference Figure 4 、 Figure 5 and Figure 6 , further comprising a lifting member 5, a first combing member 6 and a sliding member 7. The lifting member 5 can be specifically a motor-screw combination structure, the driving end of the lifting member 5 is connected to the lifting support plate 51, the sliding member 7 and the combing plate 4 are located on the lifting support plate 51, and the sliding member 7 is used to drive the sliding member 7 to slide back and forth along the length direction of the lifting support plate 51. The sliding member 7 can be specifically a motor-screw combination structure, and the driving end of the sliding member 7 is connected to the combing plate 4 on the side close to the detection table 1, so as to drive the combing plate 4 (hereinafter referred to as the first combing plate 4) to slide, while the other combing plate 4 (hereinafter referred to as the second combing plate 4) is magnetically fixed to the first combing plate 4 through a preset magnetic attraction member 48, so as to be driven by the sliding member 7 to move together with the first combing plate 4; the magnetic attraction member 48 is specifically a magnet.

[0047] In addition, a limit baffle 13 is provided at the detection table 1. The limit baffle 13 is located on the moving path of the second combing plate 4 moving with the sliding member 7, and the side wall of the limit baffle 13 is embedded with a magnet for magnetically adsorbing the second combing plate 4. When the second combing plate 4 moves to fit with the limit baffle 13 and is magnetically adsorbed, the second combing plate 4 is blocked by the limit baffle 13 and stops moving, and is fixed to one side of the detection table 1, while the first combing plate 4 is driven by the sliding member 7 to continue moving and separate from the first combing plate 4, and finally moves to the designated position on the other side of the detection table 1. At this time, a preset detection area is formed between the first combing plate 4 and the second combing plate 4. In the embodiment of the present application, the visual inspection module 22 is embedded in the upper surface of the lifting support plate 51 at the preset detection area, so as to be used to capture the yarn image of the yarn in the preset detection area from an upward perspective, and the present application assumes that all yarns in the preset detection area are within the detection range of the visual inspection module 22. In other embodiments, the visual inspection module 22 can also be installed on one side of the tension detector 21, and driven by the moving part 11 to move along the length direction of the inspection platform 1 together with the tension detector, so as to capture the yarn image when moving to the preset inspection area.

[0048] Reference Figure 4 、 Figure 6 and Figure 7 The first disentanglement member 6 includes a linkage support plate 61, a lifting frame 62, a wedge block 63, a support spring 64, and a return spring 65. The lifting frame 62 is slidably connected to one side of the detection platform 1 via the support spring 64, and the sliding direction of the lifting frame 62 is parallel to the driving direction of the lifting member 5. The support frames 321 are slidably connected to one side of the detection platform 1 via the return spring 65, and an insertion space is formed between adjacent support frames 321. The return springs 65 and wedge blocks 63 are arranged in a one-to-one correspondence with the insertion space, and all wedge blocks 63 are connected to the lifting frame 62; one end of the linkage support plate 61 is connected to the upper surface of the end of the combing plate 4.

[0049] When the combing plate 4 is located at one end of the lifting support plate 51 close to the support frame 321, and when the return spring 65 and the support spring 64 are not deformed, the lifting frame 62 is located on the rising path of the other end of the linkage support plate 61 and rises as the lifting member 5 is driven to rise and fall, so that when the lifting member 5 drives the combing plate 4 to move upward, the linkage support plate 61 pushes up the lifting frame 62, so that the lifting frame 62 and the wedge block 63 move upward, and in this process, each wedge block 63 moves upward with the lifting frame 62 and is inserted into the corresponding insertion space.

[0050] Correspondingly, the sidewalls of the support frames 321 are provided with relief surfaces for contacting corresponding wedge blocks 63. When the wedge blocks 63 are inserted into the insertion spaces, they are pushed by the wedge blocks 63, causing the corresponding support frames 321 to slide in a direction parallel to the expansion and contraction direction of the return spring 65, thereby increasing the distance between two adjacent support frames 321. Furthermore, all wedge blocks 63 are sequentially inserted into the corresponding insertion spaces in a predetermined order (e.g., extending from the center to both sides), causing all support frames 321 to slide in a predetermined order (e.g., extending from the center to both sides) under the push of the corresponding wedge blocks 63, thereby driving the support frames 321 away from each other. When the support frames 321 slide in the direction away from each other to a specified position, the combing plate 4 moves upward to a position where the yarn is inserted into the combing hole 43.

[0051] When the combing plate 4 is driven by the sliding member 7 to slide away from the support frame 321, the linkage support plate 61 breaks away from the lifting frame 62 as the combing plate 4 moves, so that the lifting frame 62 and the support frame 321 are reset under the elastic force of the reset spring 65 and the support spring 64, that is, the lifting frame 62 and the wedge block 63 move downward, and the support frame 321 moves toward the middle of all the support frames 321 and gathers together, and the insertion space becomes smaller. It should be noted that when the lifting member 62 does not drive the lifting support plate 51 to move upward, the vertical height of the linkage support plate 61 is higher than the height of the top of the combing plate 4 and lower than the height of the support frame 321 at the clearance surface for contact with the wedge block 63.

[0052] The implementation principle of a yarn tension detection system disclosed in Example 2 of the present application is as follows: the yarn bobbins are manually fixed to the support frame 321, and the free ends of the yarns corresponding to each yarn bobbin are tied to the locking member to achieve tension and fixation. Then, the lifting member 5 is activated to drive the combing plate 4 to move upward so that each yarn is independently inserted into a combing hole 43. During this process, the first loosening member 6 will drive the yarn bobbins to move away from each other to help disperse the yarns; then, the sliding member 7 drives the combing plate 4 to move to both sides of the detection platform 1. At the same time, the second loosening member 42 can be used to control the clamping member 41 to clamp the yarn, finally forming a preset detection area, and making the yarns in the preset detection area in a tensioned and distinct state.

[0053] The visual inspection module 22 captures the image of the yarn in the preset inspection area, and analyzes and determines whether there are any abnormal conditions (such as yarn entanglement, yarn breakage and frizziness, etc.). If so, a warning message is issued, and the aforementioned abnormal conditions are then manually assisted to resolve the aforementioned abnormal conditions. Finally, the moving part 11 is controlled to drive the tension detector 21 to move to each yarn to detect and obtain the yarn tension value. The controller 2 is used to obtain the yarn tension values ​​corresponding to the detection of all yarns, and connect the yarn tension values ​​of all the aforementioned yarns in the detection order to form a waveform diagram, which is displayed through the detection result output module 23. At the same time, the controller 2 is also used to compare each yarn tension value with the preset tension standard range, and determine the yarn corresponding to the yarn tension value that is not within the preset tension standard range as an abnormal yarn, and determine the position of the abnormal yarn based on the yarn image, and then control the corresponding warning light 232 to light up, so as to help the inspection personnel efficiently locate the abnormal yarn.

[0054] The above are all preferred embodiments of the present application, and are not intended to limit the scope of protection of the present application. Therefore, any equivalent changes made based on the structure, shape, and principle of the present application should be included in the scope of protection of the present application.
