Description

Technical Field

[0001] The present invention relates to the technical field of cable detection, and specifically to a device and method for detecting surface defects of polymer cables. Background Art

[0002] Cables play an important role in the national economy and are widely used both in military and civilian applications. After long-term use, due to wear and other reasons, quality problems such as aging and damage of the insulating skin are likely to occur, so safety detection is required.

[0003] For example, the patent with publication number CN113820275A discloses a new type of device and method for detecting surface defects of cables, including a fixed frame, a first winding component, a second winding component and a detection component. The first winding component, the second winding component and the detection component are all arranged on the fixed frame. The detection component is arranged between the first winding component and the second winding component. Both ends of the cable to be detected are respectively arranged on the first winding component and the second winding component. The detection component detects the cable segment between the first winding component and the second winding component. By setting the first winding component and the second winding component, the cable to be detected is placed between the two winding components, which is convenient for positioning and placing the cable to be detected. By setting the detection component between the first winding component and the second winding component, it is convenient to rotate the detector, so that the cable to be detected can be detected comprehensively. This setting is simple and convenient to operate, and the detection is comprehensive, which is beneficial to the actual detection.

[0004] During the process of winding the cable and detecting the surface defects of the cable, dust will adhere to the outer wall of the cable during the defect detection process. The adhered dust will affect the detection result, so it is necessary to clean the dust to avoid excessive dust affecting the detection result of the cable surface. Summary of the Invention

[0005] The technical problem to be solved by the present invention is to provide a device and method for detecting surface defects of polymer cables in view of the above-mentioned deficiencies in the prior art.

[0006] To solve the above technical problems, the technical solution adopted by the present invention is: a surface defect detection device for a polymer cable, including a detection table. A first fixed plate and a second fixed plate are fixedly connected to the top of the detection table. Two first vertical plates and second vertical plates are fixedly connected to the top of the detection table. A winding roller is rotatably connected between the two first vertical plates, and an unwinding roller is rotatably connected between the two second vertical plates. A fixed ring is fixedly connected to the top of the detection table. A number of detectors are arranged in a circular pattern inside the fixed ring. The cable passes through the inside of the fixed ring, and the cable can be defect-detected by the number of detectors. A stabilizing ring is fixedly connected to the top of the detection table, and the stabilizing ring is provided to maintain the stability of the cable. A cleaning mechanism is arranged on the front surface of the first fixed plate. The cleaning mechanism includes a motor. The motor is fixedly connected to the back of the second fixed plate. The output end of the motor is fixedly connected to a first rotating rod through a coupling. The first rotating rod movably passes through the second fixed plate and extends towards its front surface. A first gear is fixedly connected to the outer wall of the first rotating rod. A brush roller is fixedly connected to the outer wall of the first rotating rod. The number of the first rotating rod, the first gear, and the brush roller is two, and the two first gears are meshed with each other. The two brush rollers are provided to clean the dust inside the cable.

[0007] Preferably, the first rotating rod movably passes through the first fixed plate and extends outwards. A first connecting rod is fixedly connected to the extending end of the first rotating rod. A second connecting rod is rotatably connected to the front surface of the first connecting rod. One end of the second connecting rod is rotatably connected to a connecting plate. A scraper is fixedly connected to the right side of the connecting plate. When the first rotating rod rotates, it drives the first connecting rod and the second connecting rod to rotate, so as to drive the scraper on the left side of the connecting plate to move horizontally back and forth. The dust on the brush roller can be scraped and cleaned by the scraper, so as to prevent the cleaning effect from being affected due to excessive dust. The horizontal reciprocating movement of the scraper can continuously adjust the contact depth with the brush roller. For dust with strong viscosity, increasing the contact depth can more effectively remove it. For loose dust, reducing the contact depth can meet the requirements. And the reciprocating adjustment can prevent the scraper from always contacting the bristles at the same position, reducing local wear.

[0008] Preferably, a third vertical plate is fixedly connected to the bottom of the connecting plate. A limiting rod is fixedly connected to the left side of the third vertical plate. The first fixed plate is sleeved on the outer wall of the limiting rod. The limiting rod is provided to limit the connecting plate, so that the connecting plate always maintains horizontal movement.

[0009] Preferably, a reciprocating wire groove is formed in the outer wall of the first rotating rod. A wire sleeve is threadedly connected to the outer wall of the reciprocating wire groove. A folding rod is fixedly connected to the right side of the wire sleeve. One end of the folding rod is a telescopic end, and the other end of the folding rod is fixedly connected to a push plate. The push plate is slidably connected to the left side of the connecting plate. A limiting plate is fixedly connected to the back of the first fixing plate. The wire sleeve is slidably connected to the bottom of the limiting plate. The longitudinal movement of the wire sleeve can drive the longitudinal movement of the folding rod, so as to drive the push plate to move longitudinally through the folding rod. The movement of the push plate can push the dust on the scraper to fall, preventing the dust from accumulating on the top of the scraper and affecting the cleaning effect.

[0010] Preferably, a shaking mechanism is arranged on the front surface of the first fixing plate. The shaking mechanism includes a sleeve plate fixedly connected to the front surface of the second connecting rod. A fourth fixing plate is fixedly connected to the front surface of the first fixing plate. A movable rod movably penetrates through the inside of the fourth fixing plate.

An L-shaped rod is fixedly connected to the bottom of the rotating wheel. One end of the L-shaped rod is fixedly connected to a square frame. A cable passes through the inside of the square frame. The square frame is provided to drive the cable to shake up and down, so as to promote the fall of dust.

[0011] Preferably, a chute is formed in the top of the square frame. A slider is slidably connected to the inside of the chute. A moving plate is fixedly connected to the bottom of the slider. A support rod is hinged to the top of the slider. A third fixing plate is fixedly connected to the back of the first fixing plate. The support rod is hinged to the bottom of the third fixing plate. When the square frame moves up and down, the slider will be squeezed to move left and right inside the chute under the action of the support rod, so as to drive the moving plate at the bottom of the slider to move left and right. The left and right movement of the moving plate can drive the cable to shake left and right, so as to promote the fall of dust.

[0012] Preferably, an anti-reflection mechanism is arranged on the back of the first fixing plate. The anti-reflection mechanism includes a connecting rod. A rack is fixedly connected to the left side of the connecting rod. Two second rotating rods movably penetrate through the inside of the first fixing plate. Second gears are fixedly connected to the outer walls of the two second rotating rods. The second gears are meshed with the rack. A rectangular shaft is fixedly connected to the back of the second rotating rod. A wire brush is movably sleeved on the outer wall of the rectangular shaft. The up and down movement of the L-shaped rod drives the rack on the left side of the connecting rod to move up and down, so as to drive the second gear to rotate forward and backward, thereby driving the second rotating rod to rotate, so as to drive the upper and lower wire brushes to rotate forward and backward, thereby polishing the cable. After polishing, the reflection on the surface of the cable is reduced, and the contrast between the defect and the background is more obvious, which is convenient for the optical detection device to identify.

[0013] Preferably, a first wire groove is formed in the outer wall of the second rotating rod. A fixing rod is fixedly connected to the back of the first fixing plate. A sliding sleeve is movably sleeved on the outer wall of the fixing rod. A vertical rod is fixedly connected to the bottom of the sliding sleeve. The first wire groove is sleeved on the outer wall of the vertical rod. A push rod is fixedly connected to the top of the sliding sleeve. One end of the push rod is rotatably connected to the front of the wire brush through a bearing. By rotating the second rotating rod forward and backward, the first wire groove can be driven to rotate, thereby driving the vertical rod to move back and forth. The vertical rod drives the sliding sleeve to move on the outer wall of the fixing rod, so that the push rod can be driven to move axially, and then the wire brush can be driven to move axially. In this way, the polishing of the cable can be made more uniform and the polishing effect is better, thereby improving the detection effect.

[0014] A detection method for a surface defect detection device of a polymer cable, comprising the steps of: S1. Fix one end of the cable to the unwinding roller and the other end to the winding roller, and wind the cable. S2. The cable is polished by the wire brushes on the upper and lower sides to avoid the influence of luster on the detection effect. S3. The cable passes through the brush rollers on the upper and lower sides to clean the dust and impurities on the outer wall of the cable. The up and down movement of the square frame and the movement of the moving plate inside it drive the cable to shake, so as to promote the falling of dust. S4. The cable finally passes through the inside of the fixing ring, and the detector inside it detects the defects of the cable.

[0015] The present invention adopts the above technical solutions, which can bring the following beneficial effects: 1. For the surface defect detection device and its detection method of the polymer cable, when the cable is wound, the dust on the outer wall of the cable can be cleaned by the rotation of the brushes on the upper and lower sides. Dust may cover real surface defects. After cleaning, these defects are more easily recognized by the detection equipment, which is beneficial for detection and improves the detection effect. And by continuously adjusting the contact depth between the scraping plate and the brush roller, the dust can be cleaned more effectively, and the cleaning effect of the dust is better. Reciprocally adjusting the scraping plate can prevent the scraping plate from always contacting the bristles at the same position, reducing local wear. The axial movement of the push plate can push the dust on the scraping plate to fall, avoiding the dust accumulating on the top of the scraping plate and affecting the cleaning effect of the cable, thereby avoiding affecting the detection effect of the cable.

[0016] 2. For the surface defect detection device and its detection method of the polymer cable, the up and down movement of the square frame can drive the cable inside it to shake up and down and left and right. By shaking the cable up and down and left and right, the coverage rate of dust cleaning can be significantly improved, the cleaning effect can be enhanced, the wear of cleaning tools can be reduced, and the cleaning consistency can be improved.

[0017] 3. For the surface defect detection device and its detection method of a polymer cable, lubricant is added to the cable, which will cause reflection. By rotating the upper and lower wire brushes, the cable can be polished. After polishing, the reflection on the cable surface is reduced, and the contrast between the defect and the background becomes more obvious, facilitating the identification by the optical detection device. Moreover, the axial movement of the cable driven by the push rod can drive the wire brush to move axially, so that the polishing of the cable is more uniform and the polishing effect is better, thus improving the detection effect.

[0018] 4. For the surface defect detection device and its detection method of a polymer cable, by shaking the cable up, down, left and right, the dust and waste chips generated by polishing can be shaken off, so as to prevent the dust and waste chips from sticking to the outer wall of the cable and affecting the detection effect of the cable, thereby improving the detection effect of the cable defects.

Specific implementation manners

[0021] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0022] Please refer to Figure 1-8, an embodiment of the present invention is: a device and method for detecting surface defects of a polymer cable, including a detection table 1. A first fixed plate 2 and a second fixed plate 3 are fixedly connected to the top of the detection table 1. Two first vertical plates 411 and a second vertical plate 413 are fixedly connected to the top of the detection table 1. A winding roller 412 is rotatably connected between the two first vertical plates 411, and a pay-off roller 414 is rotatably connected between the two second vertical plates 413. A fixed ring 5 is fixedly connected to the top of the detection table 1. A number of detectors 6 are arranged in a circular pattern inside the fixed ring 5. The cable passes through the inside of the fixed ring 5, and the cable can be defect-detected by the number of detectors 6. A cleaning mechanism 7 is arranged on the front of the first fixed plate 2. The cleaning mechanism 7 includes a motor 711. The motor 711 is fixedly connected to the back of the second fixed plate 3. The output end of the motor 711 is fixedly connected to a first rotating rod 712 through a coupling. The first rotating rod 712 movably passes through the second fixed plate 3 and extends towards its front. A first gear 713 is fixedly connected to the outer wall of the first rotating rod 712. A brush roller 714 is fixedly connected to the outer wall of the first rotating rod 712. The number of the first rotating rod 712, the first gear 713, and the brush roller 714 is two, and the two first gears 713 mesh with each other. Arranging two brush rollers 714 can clean the dust inside the cable. The first rotating rod 712 movably passes through the first fixed plate 2 and extends outwards. The extended end of the first rotating rod 712 is fixedly connected to a first connecting rod 717. The front of the first connecting rod 717 is rotatably connected to a second connecting rod 718. One end of the second connecting rod 718 is rotatably connected to a connecting plate 719. A scraping plate 720 is fixedly connected to the right side of the connecting plate 719. When the first rotating rod 712 rotates, it drives the first connecting rod 717 and the second connecting rod 718 to rotate, so as to drive the scraping plate 720 on the left side of the connecting plate 719 to move horizontally back and forth. The dust on the brush roller 714 can be scraped and cleaned by the scraping plate 720, so as to avoid the influence on the cleaning effect caused by too much dust. The horizontal reciprocating movement of the scraping plate 720 can continuously adjust the contact depth with the brush roller 714. For dust with strong viscosity, increasing the contact depth can more effectively remove it. For loose dust, reducing the contact depth can meet the requirements, which can improve the effect of cleaning the dust on the brush roller 714. And the reciprocating adjustment can prevent the scraping plate 720 from always contacting the bristles at the same position, reducing local wear. A third vertical plate 723 is fixedly connected to the bottom of the connecting plate 719. A limiting rod 724 is fixedly connected to the left side of the third vertical plate 723. The first fixed plate 2 is sleeved on the outer wall of the limiting rod 724. Arranging the limiting rod 724 can limit the connecting plate 719, so that the connecting plate 719 always moves horizontally. A reciprocating thread groove 715 is opened on the outer wall of the first rotating rod 712. A thread sleeve 716 is threadedly connected to the outer wall of the reciprocating thread groove 715. A folding rod 721 is fixedly connected to the right side of the thread sleeve 716. One end of the folding rod 721 is a telescopic end.

The pushing plate 722 is slidably connected to the left side of the connecting plate 719.A limiting plate 725 is fixedly connected to the back of the first fixing plate 2. A wire sleeve 716 is slidably connected to the bottom of the limiting plate 725. The longitudinal movement of the wire sleeve 716 can drive the folding rod 721 to move longitudinally, thereby driving the push plate 722 to move longitudinally through the folding rod 721. The movement of the push plate 722 can push the dust on the scraper 720 to fall, preventing dust from accumulating on the top of the scraper 720 and affecting the cleaning effect.

The cable passes through the inside of the upper and lower wire brushes 916, the square frame 814, the brush roller 714, the stabilizing ring 10, and the fixing ring 5 in sequence. First, the motor 711 is started. The motor 711 drives the first rotating rod 712 to rotate. The first rotating rod 712 drives the first gear 713 to rotate. The rotation of the two first gears 713 drives the two first rotating rods 712 to rotate, thereby driving the two brush rollers 714 to rotate to clean the outer wall of the cable. When the first rotating rod 712 rotates, it drives the first connecting rod 717 and the second connecting rod 718 to rotate, thereby driving the scraper 720 on the left side of the connecting plate 719 to move horizontally back and forth. The dust on the brush roller 714 can be scraped and cleaned by the scraper 720 to prevent excessive dust from affecting the cleaning effect. The horizontal reciprocating movement of the scraper 720 can continuously adjust the contact depth with the brush roller 714. For dust with strong viscosity, increasing the contact depth can more effectively remove it. For loose dust, reducing the contact depth can meet the requirements, which can improve the effect of cleaning the dust on the brush roller 714. And the reciprocating adjustment can prevent the scraper 720 from always contacting the bristles at the same position, reducing local wear. When the first rotating rod 712 rotates, it drives the reciprocating wire groove 715 to rotate. When the reciprocating wire groove 715 rotates, it drives the wire sleeve 716 to move longitudinally. The longitudinal movement of the wire sleeve 716 can drive the folding rod 721 to move longitudinally, thereby driving the push plate 722 to move longitudinally through the folding rod 721. The movement of the push plate 722 can push the dust on the scraper 720 to fall, preventing dust from accumulating on the top of the scraper 720 and affecting the cleaning effect. When the cable passes through the detector 6 of the fixing ring 5, the surface defects of the cable can be detected.

Through the left and right movement of the moving plate 817, the cable can be driven to shake left and right, so as to promote the dust to fall off.

[0025] Working principle: When the second connecting rod 718 rotates, it will drive the sleeve plate 811 to move up and down.
