Description

Technical Field

[0001] The invention belongs to the technical field of non-woven fabric detection, and in particular relates to a mobile pressing component and a pressing method thereof for a non-woven fabric surface defect detection device. Background Art

[0002] Defects on non-woven fabrics are the most important factor affecting the quality grade of non-woven fabrics. Defect detection is an important part of its quality management. Traditional fabric defect inspection relies on manual subjective judgment, lacks consistency and reliability of inspection, and when manually inspecting the defective area, misjudgment may occur due to long-term use of the eyes, which is not conducive to the health of the staff.

[0003] The patent with application number CN202322286021.1 discloses a clamping and positioning device for non-woven fabric surface defect detection, including two support plates, two conveying rollers and a conveyor belt, the conveying roller is located between the two support plates and is rotatably connected to the support plates, the conveyor belt is rotatably connected to the conveying roller, a clamping and positioning assembly is arranged between the support plates, the clamping and positioning assembly includes multiple groups of pressing rollers for clamping and multiple groups of tensioning rods for positioning, the pressing roller is located between the two support plates and is movably connected to the support plates, the tensioning rods are symmetrically arranged and are movably connected to the support plates The surface of the pressing roller contacts the surface of the conveyor belt, the pressing roller and the tensioning rod rotate relative to each other to tighten the fabric, and the non-woven fabric is pulled toward the wall of the floating plate. The symmetrically arranged tensioning rods simultaneously tighten the non-woven fabric in opposite directions, so that the non-woven fabric is flattened, reducing the generation of wrinkles on the non-woven fabric, and facilitating the detection device to detect the non-woven fabric. However, when the above-mentioned technical solution is used, the device may become fatigued as the mechanical device is continuously used, so that it cannot ensure that the fabric is always in a flat and stable state by only relying on the pressing roller and the tensioning rod to rotate relative to each other to tighten the fabric.

[0004] At the same time, in the process of non-woven fabric defect detection, relying solely on the camera component cannot accurately identify the defects in the target area, and it is easy to misjudge the defects. In addition, due to the change in the tension of the non-woven fabric, it is impossible to ensure that the non-woven fabric passing through the camera component is in a taut state, which affects the normal detection of defects.

[0005] Therefore, in order to solve the above-mentioned technical problems, a mobile pressing assembly and a pressing method thereof for a non-woven fabric surface defect detection device are proposed. Summary of the invention

[0037] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0038] Embodiment 1

[0039] like Figure 1-Figure 2 As shown, a non-woven fabric surface defect detection device includes a bearing component 1 for carrying and protecting the component, a heat dissipation component 3 is connected to the bearing component 1, and the heat dissipation component 3 is used to convert the heat generated inside the bearing component 1 to ensure the stable service life of the device, the bearing component 1 includes a supporting shell 101, a carrying cavity 102 is opened in the supporting shell 101, and an identification component 4 for detecting defects on the non-woven fabric 10 is connected in the carrying cavity 102, and a moving component 2 for transmitting the non-woven fabric 10 is penetrated through the supporting shell 101, and the non-woven fabric 10 is connected to the moving component 2, and the identification component 4 can identify the non-woven fabric 10 on the moving component 2, that is, during the use of the defect detection device, the non-woven fabric 10 is first connected to the moving component 2, and then the non-woven fabric 10 is driven to move by the rotation of the moving component 2, and the defects on the surface of the non-woven fabric 10 are identified and detected by the identification component 4 during the movement.

[0040] In order to improve the recognition efficiency of the recognition component 4 for defects and reduce the occurrence of defect recognition errors, the recognition component 4 includes a recognition module 401, and the recognition module 401 is connected to the cavity wall of the carrying cavity 102. The end of the recognition module 401 close to the moving component 2 is connected to a capturer 402. The surface of the non-woven fabric 10 is scanned and recorded by the capturer 402, and the recorded data is uploaded to the recognition module 401. The recognition module 401 is used to analyze and record the data to determine the location of the target defect. It should be noted that the components of the recognition module 401 are existing technologies and will not be elaborated on here.

[0041] When the defect detection device is in use, the non-woven fabric 10 is first passed through the moving component 2, and the non-woven fabric 10 is flattened by the moving component 2, so as to reduce the probability of wrinkles on the non-woven fabric 10 on the moving component 2, thereby improving the capture accuracy of the capture device 402 when scanning and capturing the non-woven fabric 10, thereby improving the detection accuracy of the defect detection device and avoiding recognition errors.

[0042] Embodiment 2

[0043] In order to ensure the accuracy of detecting the defects on the surface of the non-woven fabric and avoid the influence of the wrinkles of the non-woven fabric 10 on the detection result, a second embodiment is proposed, and the specific contents are as follows.

[0044] like Figure 3-Figure 9 As shown, a mobile pressing component is mainly used to press and flatten the non-woven fabric 10 to improve the accuracy of defect detection, including the mobile component 2 in the first embodiment, the mobile component 2 includes a mobile frame 201 connected to the bearing component 1, the identification component 4 can scan and detect the non-woven fabric 10 on the mobile frame 201, and the end of the mobile frame 201 close to the identification component 4 is connected with a bearing frame 202. In this embodiment, the projection view of the mobile frame 201 observed from the direction of the identification component 4 is a rectangle, wherein the bearing frame 202 is in the shape of a "U" and is located in the middle of the mobile frame 201, and a pressing component is connected to the bearing frame 202. Part 5, the movable frame 201 is connected with an adjusting component 6 for adjusting the tension of the non-woven fabric 10. In the present embodiment, the adjusting component 6 is located in the middle of the movable frame 201, and working components 8 are connected on both sides of the adjusting component 6 to ensure that the non-woven fabric 10 is always in a tensioned state when moving over a long distance, thereby improving the transmission rate of the non-woven fabric 10 and the winding rate after transmission. Two conveying components 7 are provided on the side of the working component 8 away from the adjusting component 6. The two conveying components 7 are respectively located on both sides of the movable frame 201 distributed in the length direction, and the two conveying components 7 are used to achieve the stability of the moving rate of the non-woven fabric 10.

[0045] The working component 8 includes a marking rod 801 for indicating the position of the defect, and the marking rod 801 is located at the end of the traveling direction of the non-woven fabric 10. A detection rod 802 for preliminarily identifying the position of the defect is provided on the side of the adjustment component 6 away from the marking rod 801. After the non-woven fabric 10 passes through the detection rod 802, the catcher 402 identifies and detects the position on the non-woven fabric 10, thereby further improving the recognition accuracy of the device. The marking rod 801 and the detection rod 802 are movably connected to the moving frame 201 at both ends along the length distribution. The marking rod 801 and the detection rod 802 are respectively located on both sides of the adjustment component 6. When the moving frame 201 moves, the non-woven fabric 10 first passes through the detection rod 802 and then passes through the marking rod 801. On the one hand, the marking rod 801 and the detection rod 802 are used to realize the normal transportation of the non-woven fabric 10 on the conveying component 7. On the other hand, the marking rod 801, the detection rod 802 and the recognition component 4 can be used to improve the detection accuracy and recognition efficiency of the defects.

[0046] Since the composition and shape of the defect area at the location where the defect of the non-woven fabric 10 occurs are different from the shape of the non-woven fabric 10 in a normal state, the friction force in the defect area is different from the friction force in the normal area. In order to ensure that the detection rod 802 can preliminarily identify the defect position of the non-woven fabric 10, a friction sensor is connected to the detection rod 802, and the detection range of the friction sensor is greater than or equal to the size of the non-woven fabric 10 passing through the detection rod 802.

[0047] When the non-woven fabric 10 is connected and rubbed against the conveying component 7, the working component 8 and the adjusting component 6 respectively, the non-woven fabric 10 is controlled to be transported through the conveying component 7, and during the transportation process, when the pressure of the non-woven fabric 10 borne by the working component 8 decreases, it means that the non-woven fabric 10 is not in a tight state, which will cause the recognition component 4 to have recognition errors during the recognition process, and then by adjusting the height of the adjusting component 6 and controlling the pressing component 5 to contact and press the non-woven fabric 10, the state of the non-woven fabric 10 is stabilized. In this process, the friction force between the contact of the non-woven fabric 10 is identified by the detection rod 802, and the position of the friction abnormality identified by the detection rod 802 is compared with the defect area identified by the capture device 402 to ensure the accuracy of the identified defect area, and when the defect position of the non-woven fabric 10 passes through the marking rod 801, the marking rod 801 is used to mark the target area.

[0048] In order to improve the stability of the non-woven fabric 10 during the transmission process, the two conveying components 7 further include conveying rollers 701, and the two conveying rollers 701 are respectively located on both sides of the movable frame 201 along the length direction, and the movable frame 201 is connected with four inclined grooves 702, and the two ends of the conveying rollers 701 are respectively slidably connected in the inclined grooves 702, and the height of the conveying rollers 701 can be adjusted through the inclined grooves 702 to ensure that the conveying component 7 can effectively move the non-woven fabric 10 under any circumstances, and when the non-woven fabric 10 is installed, the conveying rollers 701 can be prompted to slide along the inclined grooves 702, thereby increasing the height of the conveying rollers 701, thereby improving The efficiency of installing the non-woven fabric 10 is improved, and the height of the conveying roller 701 on the movable frame 201 is higher than the adjusting component 6, that is, when the height of the adjusting component 6 is higher than the conveying roller 701, the friction between the conveying roller 701 on one side and the non-woven fabric 10 will increase, and the friction between the conveying roller 701 on the other side and the non-woven fabric 10 will decrease, which will cause the non-woven fabric 10 to become unstable during the transmission process. In severe cases, the non-woven fabric 10 will accumulate on the movable frame 201, affecting the transmission rate of the non-woven fabric 10. In order to ensure that the non-woven fabric 10 can maintain a normal transmission path, the height of the conveying roller 701 is set to be higher than the horizontal height of the adjusting component 6.

[0049] In order to improve the control of the tension of the non-woven fabric 10, the pressing assembly 5 further includes two pressing rollers 501, and telescopic frames 502 are rotatably provided at both ends of the pressing roller 501, and the telescopic frames 502 are connected to the supporting frame 202, and the two pressing rollers 501 are respectively close to the two conveying rollers 701 but do not contact each other, that is, the position of the pressing roller 501 is controlled by the telescopic frame 502, so as to realize the control of the contact pressure between the pressing roller 501 and the non-woven fabric 10, and when necessary, the self-rotation of the pressing roller 501 can assist the transmission of the non-woven fabric 10, and the two pressing rollers 501 can be used to change the transmission path of the non-woven fabric 10 during the transmission process, so as to eliminate the wrinkles generated on the non-woven fabric 10 and improve the accuracy of defect detection.

[0050] In order to facilitate the working component 8 to identify the tensioning force of the non-woven fabric 10 during the transmission process, and to prevent the non-woven fabric 10 from being damaged due to excessive tensioning force, four sliding grooves 2011 are respectively opened on the mobile frame 201, and the four sliding grooves 2011 correspond to each other, and each sliding groove 2011 is connected to an elastic component 9, and the elastic component 9 includes a connecting block 901, and the connecting block 901 is slidably connected in the sliding groove 2011. One end of the connecting block 901 is connected to a spring 902, and the spring 902 is far One end away from the connecting block 901 is fixedly connected in the sliding groove 2011, and one end of each connecting block 901 away from the spring 902 is connected to the working component 8. When the non-woven fabric 10 is normally transmitted in the moving component 2, the non-woven fabric 10 contacts the working component 8, which will cause the spring 902 to stretch or shorten, thereby ensuring the stability of the ductility of the non-woven fabric 10. When the force on the spring 902 is reduced, it means that the non-woven fabric 10 is loose or wrinkled on the moving frame 201, affecting the defect recognition efficiency of the capturer 402 in the target area.

[0051] In order to ensure that the non-woven fabric 10 can be prompted to fully identify the surface of the non-woven fabric 10 by the identification component 4 when passing through the identification component 4, the adjustment component 6 further includes a telescopic portion 604, one end of the telescopic portion 604 is connected to the mobile frame 201, and the end of the telescopic portion 604 away from the mobile frame 201 is connected to a support plate 603, and the height of the support plate 603 is regulated by the telescopic portion 604, and the end of the support plate 603 away from the telescopic portion 604 is connected to a movable rod 602, and the movable rod 602 is away from the support plate 603. One end is connected with a movable plate 601. When the non-woven fabric 10 is moving, the pressing component 5 contacts the non-woven fabric 10, which will cause the movable plate 601 to drive the movable rod 602 to be compressed, and the position of the catcher 402 is facing the plate surface of the movable plate 601. It can detect defects on the surface of the non-woven fabric 10 passing through the plate surface of the movable plate 601, and judge the tension of the non-woven fabric on the surface of the movable plate 601 according to the compression depth of the movable rod 602, to ensure that the recognition accuracy of the recognition component 4 is improved while meeting the requirements of accurate recognition.

[0052] Furthermore, a storage cavity 8012 for placing marking pigment is provided in the marking rod 801, and a nozzle 8011 is connected to one side of the storage cavity 8012. The nozzle 8011 is used to spray the marking pigment in the storage cavity 8012 to mark the defect position.

[0053] In order to improve the accuracy of the nozzle 8011 in marking the defect position, the nozzle 8011 is further controlled by the detection rod 802 and the identification module 401, that is, the marking position of the nozzle 8011 is determined through the mutual cooperation between the detection rod 802 and the identification module 401.

[0054] It should be noted that in actual use, a number of rotating rollers can be connected to the movable frame 201 to support the non-woven fabric 10 to ensure that the non-woven fabric 10 can move along the movable component 2. Due to the different sizes and weights of the non-woven fabric 10, the positions of the rotating rollers are also different. Therefore, in this solution, the positions of the rotating rollers are not specifically limited.

[0055] Among them, Fig. 9 As shown, the position of the non-woven fabric 10 on the mobile pressing assembly is specifically described, and in order to reduce the difficulty of describing the winding position of the non-woven fabric 10, the end close to the detection rod 802 is set as the right end (i.e. the starting end), and the end close to the marking rod 801 is set as the left end (i.e. the removal end). When winding, the non-woven fabric 10 first passes through the bottom of the right conveying roller 701, and respectively collides with the detection rod 802 and the upper end of the movable plate 601, and at the same time passes through the lower end of the marking rod 801, and finally moves out from the upper side of the left conveying roller 701, and in the process of transmitting the non-woven fabric 10, the collision between the pressing roller 501 and the non-woven fabric 10 is controlled, and the two pressing rollers 501 are respectively located between the marking rod 801 and the left conveying roller 701, and between the detection rod 802 and the right conveying roller 701.

[0056] When in use, the non-woven fabric 10 is moved by means of two conveying rollers 701, and the non-woven fabric 10 is pressed by means of two pressing rollers 501, ensuring that the tension of the non-woven fabric 10 in the area can be adjusted during use to ensure the accuracy of defect detection, and in actual use, the friction between the non-woven fabric 10 and the detection rod 802 is identified during movement, and the tension of the non-woven fabric 10 is identified according to the compression degree of the movable rod 602, ensuring that the stretch of the non-woven fabric 10 when passing through the identification component 4 will not affect the effect of defect detection.

[0057] During the transmission of the non-woven fabric 10, the tension of the non-woven fabric 10 is judged by the elastic change of the elastic component 9 and the compression degree of the movable rod 602, ensuring that the state of the non-woven fabric 10 is always in a state that can be recognized, and when the tension of the non-woven fabric 10 is reduced but does not affect the transmission, the length of the elastic component 9 will be reset, and the length of the movable rod 602 will be extended, so as to ensure that the non-woven fabric 10 can still be recognized by the recognition component 4, but when the tension of the non-woven fabric 10 continues to decrease, on the one hand, it will cause the detection rod 80 On the other hand, it is impossible to perform friction detection on the surface of the non-woven fabric 10. On the other hand, it will cause wrinkles on the non-woven fabric 10, which will affect the recognition state of the recognition component 4 and the transmission of the non-woven fabric 10. At this time, while maintaining the normal rotation of the conveying roller 701, by adjusting the telescopic length of the telescopic part 604 and the contact between the pressing roller 501 and the non-woven fabric 10, the transmission distance of the non-woven fabric 10 on the moving frame 201 is increased, thereby increasing the tension of the non-woven fabric 10 on the moving frame 201 and ensuring the smooth progress of defect detection.

[0058] When the tension of the non-woven fabric 10 is at a normal standard, the non-woven fabric 10 is in a stretched state when passing through the movable plate 601, which is convenient for identifying its defects using the identification component 4. In the process of the movement of the non-woven fabric 10, the non-woven fabric 10 will generate friction with the detection rod 802, so that the friction sensor is used to identify and detect the surface of the non-woven fabric passing through the detection rod 802, that is, at this time, the defect position on the surface of the non-woven fabric 10 is identified through the friction detection between the non-woven fabric 10 and the detection rod 802, and the identification result is uploaded to the identification module 401. As the non-woven fabric 10 moves, the detection position moves to the surface of the movable plate 601, and then a secondary identification detection is performed on the captured device 402, so as to ensure the accuracy of the defect position detection and reduce the error of the defect detection. When the capturer 402 captures and is confirmed by the identification module 401, the marker in the storage cavity 8012 is marked on the target position through the nozzle 8011, which is convenient for the staff to quickly identify the defect position.

[0059] In the process of transmitting the non-woven fabric 10, wrinkles may appear due to winding or in the transmission process, and in the process of identification by the identification component 4, the wrinkles may be mistaken for defects due to problems with the capturer 402 or the identification module 401, resulting in identification errors. When the wrinkled non-woven fabric 10 passes through the detection rod 802, the friction force on the surface of the detection rod 802 will increase instantaneously due to the influence of the wrinkles, and the spring 902 will also be driven to contract, and the wrinkle state will be uploaded to the identification module 401, thereby ensuring that the capturer 402 will not make misjudgments when capturing wrinkles, thereby ensuring the accuracy of wrinkle detection.

[0060] Embodiment 3

[0061] A clamping method implemented by using the mobile clamping assembly in the second embodiment includes the following steps:

[0062] Step 1: The non-woven fabric 10 is sequentially passed through the conveying component 7, the working component 8 and the adjusting component 6, so that the conveying component 7 can convey the non-woven fabric 10;

[0063] Step 2: During the conveying process, the elastic component 9 and the movable rod 602 are used to constrain the position of the non-woven fabric 10 to ensure that the conveying roller 701 can stably convey the non-woven fabric 10;

[0064] Step 3: When the pressure on the elastic component 9 and the movable rod 602 is reduced during the conveying process, the movable plate 601 can be raised by the movable rod 602 to adjust the tightness of the non-woven fabric 10, thereby ensuring the accuracy of defect recognition by the recognition component 4;

[0065] Step 4. When the non-woven fabric 10 becomes excessively loose, the pressing roller 501 is adjusted to contact the non-woven fabric 10, and the extension of the telescopic portion 604 is controlled to extend the transmission path of the non-woven fabric 10, so as to increase the transmission path of the non-woven fabric 10 on the movable frame 201, adjust the tightness of the non-woven fabric 10, and ensure that the non-woven fabric 10 is always in a state where it can be stably detected by the identification component 4.
