DETAILED DESCRIPTION

[0035] Exemplary embodiments will be described in detail herein, examples of which are shown in the accompanying drawings. When the following description refers to the drawings, the same numbers in different drawings represent the same or similar elements unless otherwise indicated. The embodiments described in the following exemplary embodiments do not represent all embodiments consistent with the present disclosure. Instead, they are merely examples of devices and methods consistent with some aspects of the present disclosure as detailed in the appended claims.

[0036] The exemplary embodiment of the present disclosure provides a detection device, which provides a first connecting member and a trigger on a substrate, and provides a detection hole on a movable member movably connected to the first connecting member, so that the movable member can trigger the trigger when the to-be-detected yarn bundle passing through the detection hole has hair, so as to generate a detection signal through the trigger, thereby realizing the function of the detection member to detect hair on the to-be-detected yarn bundle. The detection device can realize automatic detection of hair on the to-be-detected yarn bundle through a simple structure, improve detection accuracy and detection efficiency, reduce labor costs, and thus ensure the uniformity of quality of products prepared from the to-be-detected yarn bundle.

[0037] In an exemplary embodiment, a detection device is provided, the detection device includes a detection member 10, the detection member 10 is used to detect hair on a to-be-detected tow, and the detection member 10 may be, for example, one or more. The to-be-detected tow may be, for example, a carbon fiber tow for preparing a prepreg product, and the hair on the to-be-detected tow may include hair and hair balls.

[0038] refer to Figures 1 to 3 As shown, the detection member 10 includes a substrate 11, a trigger 14 and a movable member 15. The substrate 11 is provided with a first connecting member 12 and a through slot 13 parallel to the extension direction of the substrate 11. The trigger 14 is provided on the substrate 11, and the trigger 14 is used to generate a detection signal in a triggered state. The movable member 15 passes through the through slot 13, the first end of the movable member 15 is movably connected to the first connecting member 12, and the second end of the movable member 15 is provided with a detection hole 16, through which the to-be-detected silk bundle passes, and the movable member 15 is used to move to trigger the trigger 14 when the to-be-detected silk bundle has hair.

[0039] The substrate 11, as a bearing component of the detection component 10, is used to provide support for other components of the detection component 10 and can be used to fix the detection component 10. A first connecting member 12 is provided on the substrate 11. The first connecting member 12 can be provided, for example, on the upper side of the substrate 11 along the Y direction and in the middle position along the X direction, and is used to be movably connected with the movable member 15 so that the movable member 15 can move relative to the substrate 11. A through groove 13 parallel to the extension direction of the substrate 11, that is, the X direction, is also provided on the substrate 11. The through groove 13 runs through the upper and lower sides of the substrate 11 along the Y direction so that the movable member 15 can pass through the substrate 11. The length of the through groove 13 along the X direction can be set according to the range of motion of the movable member 15, and the width of the through groove 13 along the Z direction can be set according to the size of the part of the movable member 15 passing through the substrate 11.

[0040] A trigger 14 is also provided on the substrate 11. The trigger 14 can be provided, for example, on the upper side of the substrate 11 along the Y direction or at the end position along the X direction. The trigger 14 can switch between a non-trigger state and a trigger state by means of a contact or non-contact sensing movable part 15. When the trigger 14 is in the trigger state, a detection signal can be generated. The detection signal is used to indicate that there are hair balls on the yarn bundle to be detected at this time.

[0041] The movable member 15 passes through the through groove 13 of the substrate 11, and the first end of the movable member 15 is movably connected to the first connecting member 12. When the first connecting member 12 is arranged on the upper side of the substrate 11 along the Y direction, the first end of the movable member 15 is also located on the upper side of the substrate 11 along the Y direction. At this time, the second end of the movable member 15 is located on the lower side of the substrate 11 along the Y direction. The second end of the movable member 15 is provided with a detection hole 16, and the yarn bundle to be detected passes through the detection hole 16 on the movable member 15 to detect the hair.

[0042] like Figure 1 As shown, when there is no hair on the yarn bundle to be detected, the yarn bundle to be detected can smoothly pass through the detection hole 16, so that the movable member 15 is in the initial position and remains stationary. Figure 4 As shown, when there are hairs on the to-be-detected silk bundle, the hairs on the to-be-detected silk bundle will drive the movable member 15 to leave the initial position when the to-be-detected silk bundle passes through the detection hole 16, generating movement relative to the substrate 11 and the trigger 14 fixed on the substrate 11. The movement of the movable member 15 relative to the trigger 14 can trigger the trigger 14, so that the trigger 14 generates a detection signal in the triggered state, indicating through the detection signal that there are hairs and hair balls on the to-be-detected silk bundle at this time, thereby realizing automatic detection of hairs on the to-be-detected silk bundle.

[0043] In this embodiment, by arranging the first connecting member 12 and the trigger 14 on the substrate 11, and arranging the detection hole 16 on the movable member 15 movably connected to the first connecting member 12, the movable member 15 can trigger the trigger 14 when the to-be-detected yarn bundle passing through the detection hole 16 has hair, so as to generate a detection signal through the trigger 14, thereby realizing the function of the detection member 10 to detect hair on the to-be-detected yarn bundle. The detection device can realize the automatic detection of hair on the to-be-detected yarn bundle through a simple structure, improve the detection accuracy and detection efficiency, reduce the labor cost, and thus ensure the quality uniformity of the product prepared from the to-be-detected yarn bundle.

[0044] In some embodiments, reference Figures 1 to 3 As shown, the first connecting member 12 includes a fixed ear, and the movable member 15 includes a rotating shaft 17, a detection plate 18, and a second connecting member 19. The rotating shaft 17 is arranged at the first end of the movable member 15, and the rotating shaft 17 passes through the connection hole on the fixed ear to be rotatably connected with the fixed ear. The detection plate 18 is arranged at the second end of the movable member 15, and the detection plate 18 is perpendicular to the base plate 11 when in the initial position, and the detection hole 16 is arranged on the detection plate 18. The second connecting member 19 passes through the through slot 13, and the second connecting member 19 is used to connect the rotating shaft 17 and the detection plate 18.

[0045] A pair of fixed ears as the first connecting member 12 are arranged on both sides of the substrate 11 along the Z direction, and a connecting hole is provided on the fixed ears. A rotating shaft 17 is arranged at the first end of the movable member 15 and extends along the Z direction. The rotating shaft 17 is rotatably connected to the fixed ears by passing through the connecting hole on the fixed ears, so as to realize the movable connection between the first end of the movable member 15 and the first connecting member 12.

[0046] The detection plate 18 is arranged at the second end of the movable member 15. Since the movable member 15 passes through the base plate 11 through the through slot 13, when the fixed ear is located on the upper side of the base plate 11 along the Y direction, the detection plate 18 is located on the lower side of the base plate 11 along the Y direction. The detection plate 18 is perpendicular to the base plate 11 in the initial position, that is, the detection plate 18 is perpendicular to the X direction in the initial position. The detection plate 18 is provided with a detection hole 16 for passing the tow to be detected. The second connecting member 19 passes through the through slot 13 and the two ends are respectively connected to the rotating shaft 17 and the detection plate 18, so that the detection member 10 passes through the base plate 11 through the through slot 13.

[0047] like Figure 1 As shown, when there is no hair on the yarn bundle to be detected, the yarn bundle to be detected can smoothly pass through the detection hole 16, and at this time, the detection plate 18 is in the initial position, that is, it remains perpendicular to the base plate 11. Figure 4 As shown, when there are hairs on the wire bundle to be detected, the hairs on the wire bundle to be detected will drive the detection plate 18 to leave the initial position when the wire bundle to be detected passes through the detection hole 16. At this time, the detection plate 18 and the second connecting member 19 rotate around the rotating shaft 17 together, generating movement relative to the base plate 11 and the trigger 14.

[0048] In this embodiment, the fixed ear is used as the first connecting member 12, and the movable member 15 is formed by setting the rotating shaft 17, the detection plate 18 and the second connecting member 19. The movable connection between the movable member 15 and the first connecting member 12 can be realized by the rotating connection between the rotating shaft 17 and the fixed ear, so that when the to-be-detected silk bundle with hair passes through the detection hole 16 set on the detection plate 18, it can drive the detection plate 18 and the second connecting member 19 to rotate around the rotating shaft 17, so as to generate a relative movement of the trigger 14, thereby triggering the trigger 14, and realizing the automatic detection of the hair on the to-be-detected silk bundle. In addition, the detection plate 18 is set to be perpendicular to the base plate 11 in the initial position, so that the detection plate 18 can be roughly perpendicular to the to-be-detected silk bundle in the initial position, which is convenient for the detection of hair on the to-be-detected silk bundle.

[0049] In the actual production process, a large number of to-be-detected yarn bundles need to be inspected for hair fibers. If the detection member 10 cannot detect a plurality of to-be-detected yarn bundles at the same time, a high detection efficiency cannot be guaranteed.

[0050] To solve the above problems, in some embodiments, reference Figure 3 As shown, the detection hole 16 extends in the horizontal direction, so that a plurality of to-be-detected wire bundles arranged in the horizontal direction can pass through the detection hole 16 at the same time.

[0051] The detection hole 16 on the detection plate 18 is set to extend in the horizontal direction, i.e., the Z direction, so that the size of the detection hole 16 in the horizontal direction is much larger than the diameter of the to-be-detected tow. Multiple to-be-detected tows arranged in the horizontal direction, i.e., the Z direction, can smoothly pass through the detection hole 16 at the same time. That is, if there is no hair on the multiple to-be-detected tows arranged in the horizontal direction, the movable member 15 will not move when passing through the detection hole 16 at the same time. Therefore, if the trigger 14 is not triggered, it means that there is no hair on the multiple to-be-detected tows. If the trigger 14 is triggered, it means that there is a to-be-detected tow with hair among the multiple to-be-detected tows, so that one detection member 10 can realize the synchronous detection of multiple to-be-detected tows.

[0052] In this embodiment, the detection hole 16 is set to extend in the horizontal direction, so that multiple wire bundles to be detected arranged in the horizontal direction can pass through the detection hole 16 at the same time. The multiple wire bundles to be detected arranged in the horizontal direction can be synchronously detected through one detection component 10. It is suitable for actual production scenarios where multiple wire bundles to be detected are arranged in the horizontal direction, and the detection efficiency is further improved.

[0053] In some embodiments, the size of the detection hole 16 along the height direction is configured so that when the to-be-detected yarn bundle with hairy yarn passes through the detection hole 16 , it can drive the movable part 15 to move.

[0054] The dimension of the detection hole 16 along the height direction, i.e., the Y direction, on the detection plate 18 is configured so that when the yarn bundle to be detected with hair threads passes through the detection hole 16, it can drive the movable part 15 to move, that is, the dimension of the detection hole 16 along the height direction can ensure that the yarn bundle to be detected with hair threads cannot smoothly pass through the detection hole 16 when the detection plate 18 maintains its initial position.

[0055] The height dimension of the detection hole 16 can be set to be slightly larger than the diameter of the to-be-detected wire bundle. When the to-be-detected wire bundle has hair, the sum of the height dimensions of the to-be-detected wire bundle and the hair is larger than the height dimension of the detection hole 16. The obstruction of the detection plate 18 to the hair will generate a reverse driving force, so that the to-be-detected wire bundle with hair can drive the movable member 15 to move when passing through the detection hole 16. For example, when the conventional diameter of the to-be-detected wire bundle is, for example, 0.1 mm, the height dimension of the detection hole 16 can be set to, for example, 0.2 mm.

[0056] In this embodiment, the height dimension of the detection hole 16 is configured so that the movable part 15 can be driven to move when the detected wire bundle with hairs passes through the detection hole 16. This provides a basis for the movable part 15 to move to trigger the trigger 14 when the detected wire bundle has hairs, thereby ensuring the detection accuracy of the hairs on the detected wire bundle and realizing automatic detection of the hairs.

[0057] It should be noted that since the hardness of the detection plate 18 is much greater than that of the hair, and the to-be-detected wire bundle is in a continuous conveying state, the to-be-detected wire bundle with the hair will cause the hair blocked by the detection plate 18 to deform and gradually gather when driving the movable part 15 to move, so that the hair can pass through the detection hole 16 together with the to-be-detected wire bundle after driving the detection plate 18 to move a certain distance, and will not cause the to-be-detected wire bundle with the hair to be stuck by the detection part 10 and fail to maintain the continuous conveyance and detection of the to-be-detected wire bundle.

[0058] In some embodiments, the trigger 14 includes a proximity switch, and the movable member 15 can trigger the proximity switch when it moves in a direction approaching the proximity switch.

[0059] The trigger 14 capable of generating a detection signal in a trigger state may include a proximity switch, which is a contactless position switch that can sense the presence of an object without mechanical contact with the object to be detected. The proximity switch can be activated by a signal generated when an object approaches or moves away from its sensing area, thereby reaching a trigger state. The detection plate 18 or the second connecting member 19 included in the movable member 15 can be used as a component for triggering the proximity switch. When the hair on the tow to be detected drives the movable member 15 to move in a direction close to the proximity switch, the detection plate 18 or the second connecting member 19 approaches the sensing area of ​​the proximity switch, so that the proximity switch is triggered, thereby realizing the detection of the hair on the tow to be detected. It should be noted that a protrusion or a trigger plate can also be set above the rotating shaft 17 in the height direction, i.e., the Y direction, as a component for triggering the proximity switch. When the hair on the tow to be detected drives the detection plate 18 and the second connecting member 19 to move in a direction close to the proximity switch, the protrusion or the trigger plate moves away from the sensing area of ​​the proximity switch, so that the proximity switch is triggered, and the monitoring of the hair on the tow to be detected can also be realized.

[0060] In this embodiment, the proximity switch is used as the trigger 14, so that the movable part 15 can trigger the proximity switch when it moves in the direction close to the proximity switch, thereby realizing the triggering of the trigger 14 by the movable part 15 when the yarn bundle to be detected contains hair. The characteristics of the proximity switch such as no need for contact, high reliability, and strong anti-interference ability are fully utilized, thereby reducing the wear of the device and improving the detection accuracy and stability.

[0061] In some embodiments, reference Figure 5 As shown, a plurality of detection members 10 are provided, and the plurality of detection members 10 are arranged on the detection bracket 20 along the height direction.

[0062] As mentioned above, one detection member 10 can realize synchronous detection of multiple tows to be detected arranged in the horizontal direction. In order to further improve the detection efficiency and realize synchronous detection of a larger number of tows to be detected, multiple detection members 10 can be simultaneously arranged in the detection device, and each detection member 10 can be made of the same material and size. Multiple detection members 10 are arranged on the detection bracket 20 along the height direction, i.e., the Y direction. For example, the substrate 11 of the detection member 10 can be fixedly connected to the detection bracket 20, and the synchronous detection of multiple tows to be detected arranged along the height direction can be realized by multiple detection members 10.

[0063] In this embodiment, a plurality of detection members 10 are arranged in the detection device, and the plurality of detection members 10 are arranged on the detection bracket 20 along the height direction. The plurality of detection members 10 can be used to synchronously detect a plurality of wire bundles to be detected arranged along the height direction. This is suitable for actual production scenarios where a plurality of wire bundles to be detected are arranged along the height direction, and the detection efficiency is further improved.

[0064] In some embodiments, the detection device further includes a controller, which is electrically connected to the trigger 14 .

[0065] The detection device also includes a controller, which is electrically connected to the trigger 14. When the movable part 15 moves to trigger the trigger 14 when the yarn bundle to be detected contains hair, the trigger 14 can output the generated detection signal to the controller. The controller can issue an alarm after receiving the detection signal to prompt the on-site staff so that the hair on the yarn bundle to be detected can be processed in time. The controller can, for example, be a programmable logic controller (PLC).

[0066] In this embodiment, by providing a controller electrically connected to the trigger 14 in the detection device, the detection signal generated by the trigger 14 when the yarn bundle to be detected contains hair can be received by the controller, and an alarm can be issued when the detection signal is received, thereby realizing real-time prompting of the detection results, which is conducive to timely corresponding processing of the hair on the yarn bundle to be detected.

[0067] In some embodiments, reference Figure 5 As shown, the detection device further includes a yarn withdrawing section 30 and a yarn collecting section 40. The yarn withdrawing section 30 is arranged on the upstream side of the detection member 10 along the transmission direction of the yarn bundle to be detected, and the yarn withdrawing section 30 is used to provide the yarn bundle to be detected to the detection member 10. The yarn collecting section 40 is arranged on the downstream side of the detection member 10 along the transmission direction of the yarn bundle to be detected, and the yarn collecting section 40 is used to collect the yarn bundle to be detected.

[0068] In the detection device, a yarn withdrawal section 30 is also provided on the upstream side of the detection member 10 along the transmission direction of the yarn bundle to be detected. The yarn withdrawal section 30 may include a yarn withdrawal frame, which can unwind the yarn bundle to be detected. The yarn withdrawal section 30 can provide the detection member 10 with multiple yarn bundles to be detected arranged in the horizontal direction and the height direction, so as to detect the hair on the yarn bundle to be detected through the detection member 10. A yarn gathering section 40 is also provided on the downstream side of the detection member 10 along the transmission direction of the yarn bundle to be detected. The yarn gathering section 40 may include a yarn gathering plate, for example, which can collect and gather the yarn bundle to be detected after being detected by the detection member 10, so as to facilitate the subsequent processing of the yarn bundle to be detected.

[0069] In this embodiment, by respectively arranging the yarn withdrawal section 30 and the yarn gathering section 40 on the upstream side and the downstream side of the detection member 10 along the transmission direction of the yarn bundle to be detected, the yarn withdrawal section 30 can be used to unwind the yarn bundle to be detected, so as to provide the detection member 10 with the yarn bundle to be detected, and the yarn gathering section 40 can be used to collect and gather the yarn bundle to be detected after being detected by the detection member 10, thereby ensuring the continuous transmission of the yarn bundle to be detected and improving the detection efficiency and stability.

[0070] In some embodiments, reference Figure 5 As shown, the detection device further includes a yarn spreading section 50 and a cleaning section 60. The yarn spreading section 50 is arranged at the downstream side of the yarn collecting section 40 along the transmission direction of the to-be-detected tow, and the yarn spreading section 50 is used to spread the to-be-detected tow. The cleaning section 60 is arranged at the downstream side of the yarn spreading section 50 along the transmission direction of the to-be-detected tow, and the cleaning section 60 is used to clean the to-be-detected tow.

[0071] In the detection device, a yarn spreading section 50 is also provided on the downstream side of the yarn collecting section 40 along the transmission direction of the to-be-detected yarn bundle. The yarn spreading section 50 may include, for example, a plurality of yarn spreading rollers. The yarn spreading section 50 can break up and evenly distribute the to-be-detected yarn bundles collected by the yarn collecting section 40, so that the to-be-detected yarn bundles are evenly arranged, and the uneven distribution of the to-be-detected yarn bundles can be avoided, resulting in pores in the prepreg product. A cleaning section 60 is also provided on the downstream side of the yarn spreading section 50 along the transmission direction of the to-be-detected yarn bundles, and the cleaning section 60 can remove the hair on the to-be-detected yarn bundles by adsorption, adhesion, etc., so as to clean the to-be-detected yarn bundles.

[0072] In the present embodiment, by sequentially arranging the yarn spreading section 50 and the cleaning section 60 on the downstream side of the yarn collecting section 40 along the transmission direction of the yarn bundle to be detected, the yarn spreading section 50 can be used to spread the yarn bundle to be detected, thereby ensuring the uniformity of arrangement of the yarn bundle to be detected, and the cleaning section 60 can be used to clean the yarn bundle to be detected, thereby removing fuzz and hair balls on the yarn bundle to be detected, thereby ensuring the quality and performance of the product prepared from the yarn bundle to be detected.

[0073] In some embodiments, reference Figure 5 As shown, the cleaning part 60 includes two cleaning rollers 61 arranged opposite to each other, and the to-be-detected tow passes between the two cleaning rollers 61 . The surfaces of the two cleaning rollers 61 are both provided with polyester non-woven fabrics.

[0074] The cleaning part 60 includes two cleaning rollers 61 arranged opposite to each other in the height direction, i.e., the Y direction. The surfaces of the two cleaning rollers 61 are in contact with each other or are spaced apart at a certain distance. The to-be-detected silk bundle can pass between the two cleaning rollers 61 and can drive the two cleaning rollers 61 to rotate around their respective roller axes. A layer of polyester non-woven fabric is provided on the surface of the two cleaning rollers 61. The polyester non-woven fabric can absorb and adhere to the hair on the to-be-detected silk bundle, thereby achieving the cleaning effect on the to-be-detected silk bundle.

[0075] In this embodiment, two cleaning rollers 61 arranged opposite to each other and having polyester non-woven fabrics on their surfaces are used as the cleaning part 60, and the to-be-detected wire bundle is passed between the two cleaning rollers 61. The rotation of the cleaning rollers 61 and the adsorption and adhesion of the polyester non-woven fabrics can continuously remove the hair on the to-be-detected wire bundle, thereby realizing the function of the cleaning part 60 to clean the to-be-detected wire bundle and ensuring the quality and performance of the product prepared from the to-be-detected wire bundle.

[0076] It can be understood that the detection device can also include a traction part for providing transmission power for the yarn bundle to be detected. The yarn bundle to be detected unwound by the yarn unwinding part 30 first passes through the detection part 10, and the hair on the yarn bundle to be detected is detected by the detection part 10, and then the yarn bundle to be detected is collected by the yarn collecting part 40, and then the yarn bundle to be detected is unfolded by the yarn spreading part 50 to ensure the uniform arrangement of the yarn bundle to be detected, and finally the hair on the yarn bundle to be detected is removed by the cleaning part 60.
