Description

Technical Field

[0001] The invention belongs to the technical field of copper wire detection, in particular to a surface defect detection device for copper wire. Background Art

[0002] Copper wire, as a metal material, is mainly made of pure copper or copper alloy. It has excellent electrical conductivity, thermal conductivity and corrosion resistance, and exhibits good mechanical properties. During the copper wire processing and production process, it is necessary to perform defect detection on the copper wire surface. Through defect detection, it can be determined whether there are defects on the copper wire surface, such as cracks, oxidation, inclusions, etc., so that material defects can be discovered in time to prevent potential accidents caused by defects, such as circuit short circuit, equipment failure, etc.

[0003] The patent with announcement number CN216978868U discloses a surface defect detection device for copper wire, including an active roller, a driven roller, a fixed base, a connecting plate, a display screen and a detection lens; connecting plates are vertically arranged on the front and rear sides of the surface of the fixed base, and an active roller and a driven roller are respectively arranged at both ends between the two connecting plates, one end of the active roller passes through the connecting plate and is fixedly connected to the output end of the driving motor, a strip through hole is opened on the surface of the connecting plate at the position corresponding to the roller shaft of the driven roller, both ends of the roller shaft of the driven roller pass through the strip through hole and are slidably connected to the strip through hole, both ends of the roller shaft of the driven roller are sleeved with fixing rings, support rods are symmetrically and vertically fixed on the surface of the connecting plate, a support plate is horizontally fixed on the top of the support rod, and a display screen is vertically arranged on the surface of the support plate.

[0004] However, the above technical solution still has the following deficiencies in practical application:

[0005] The surface of the copper wire is inspected by a detection lens, and the detected image is displayed on a display screen to facilitate workers to judge whether the copper wire surface has defects. Although this method can be used to judge whether the copper wire surface has defects, usually, after the inspection work is completed, the defective position on the copper wire surface needs to be repaired, so workers are required to find the defective position of the copper wire first. Since the copper wire is usually thin and the defective position may not be obvious enough, it is more difficult for workers to find the defective position of the copper wire. They may not be able to find the defective position accurately, resulting in improper handling or repair omissions, which in turn affects the repair efficiency. Summary of the invention

[0021] The beneficial effects of the present invention are as follows:

[0022] 1. The surface defect detection device for copper wire described in the present invention, with the cooperation of the reeling and winding mechanism, the display screen and the detection lens, enables the copper wire to be automatically conveyed, and the surface image of the copper wire is displayed on the display screen through the detection lens, thereby making it easier for workers to detect defects on the surface of the copper wire and helping to improve detection efficiency.

[0023] 2. The surface defect detection device for copper wire described in the present invention can attach tape to the defective position of the copper wire by utilizing an attaching mechanism. After the detection work is completed, the worker can quickly locate the defective position of the copper wire by observing the position of the tape on the surface of the copper wire, thereby avoiding the situation in which the worker has difficulty in accurately finding the defective position due to the lack of obviousness of the defective position of the copper wire during subsequent repair, and then improper handling or missed repair occurs. This is beneficial to improving the repair efficiency of the defective position. In addition, by utilizing a secondary marking mechanism, the tape attached to the defective position of the copper wire can be dyed into different colors by spraying paint with a paint spray can, and different colors correspond to different degrees of defect. During subsequent repair work, the worker can observe the color of the tape to determine the degree of defect at each defective position. Statistics show that it is beneficial for workers to formulate repair plans and improve repair efficiency. In addition, the shrink cloth is in a stretched state in the initial state, and the copper wire can pass through the through hole in the middle of the shrink cloth without contacting the shrink cloth. When the paint is sprayed out, the through hole in the middle of the shrink cloth is driven to shrink until it contacts the copper wire. At this time, with the cooperation of the cylinder and the shrink cloth, the painted tape is in a closed environment, and the paint sprayed by the paint spray can will only be concentrated inside the cylinder without splashing to the surrounding area. This avoids the situation where the paint adheres to the non-defective position of the copper wire, which is not conducive to the subsequent observation of the copper wire surface by the workers, and also ensures the cleanliness of the working environment. In addition, when the copper wire is conveyed normally, the shrink cloth is driven away from the copper wire, which can avoid the paint adhered to the edge of the through hole of the shrink cloth from adhering to the copper wire surface due to friction.

[0049] The base 1 is also provided with a secondary marking mechanism for dyeing the tape attached to the defective position of the copper wire;

[0050] The secondary marking mechanism includes a support plate three 12 fixedly connected to one side of the upper end surface of the base 1, and a cylinder 29 is fixedly connected to one side of the upper end of the support plate three 12, and a fixing ring 28 is fixedly connected to both sides of the upper end of the support plate three 12. A plurality of adjusting rods 30 are radially distributed and slidably connected to the fixing ring 28, and a shrinkage cloth 31 is fixedly connected to both ends of the adjusting rod 30. The shrinkage cloth 31 is made of elastic material and has a through hole in the middle. The copper wire can pass through the through hole in the middle of the shrinkage cloth 31 and the inner cavity of the cylinder 29. A plurality of spray cans 48 are arranged on the upper end of the cylinder 29, and the nozzles of the spray cans 48 pass through the upper side of the cylinder 29 and extend to the inner cavity of the cylinder 29.

[0051] A connecting rod 35 is rotatably provided on one side of the adjusting rod 30, and an adjusting ring 34 is rotatably provided on one end of the connecting rod 35. A threaded rod 33 is threadedly connected to one side of the adjusting ring 34. The fixing ring 28 close to one side of the adjusting ring 34 is fixedly connected to a motor 6 32 on its left side. The threaded rod 33 rotatably passes through the fixing ring 28 and is fixedly connected to the output end of the motor 6 32.

[0052] Slide rod 3 43 is fixedly connected to both ends of one side of cylinder 29, and slide rod 3 43 is slidably connected to threaded block 46, and electric push rod 3 45 is fixedly connected to one side of the upper end of threaded block 46, and pressure block 47 is fixedly connected to the piston end of electric push rod 3 45.

[0053] One end of the threaded block 46 is threadedly connected to a threaded rod 3 44 , both ends of the threaded rod 3 44 are rotatably arranged on the cylinder 29 , one side of the cylinder 29 is fixedly connected to a motor 8 50 , and the output end of the motor 8 50 is fixedly connected to one end of the threaded rod 3 44 .

[0054] Specifically, when the existing copper wire surface defect detection device is used, the detection lens 49 is used to detect the copper wire surface, and the detected image is displayed on the display screen 11, so that the worker can judge whether the copper wire surface has defects. Although this method can be used to judge whether the copper wire surface has defects, usually, after the detection work is completed, the defect position on the copper wire surface needs to be repaired, so the worker needs to find the defect position of the copper wire first. Since the copper wire is usually thin and the defect position may not be obvious enough, it is more difficult for the worker to find the defect position of the copper wire. The defect position may not be found accurately, resulting in improper treatment or repair omissions, thereby affecting the repair efficiency.

[0055] Therefore, in order to solve the above problems, when the present embodiment is used, the tape roll 14 is plugged into the mounting roller 27, and one end of the tape wound on the surface of the tape roll 14 is pulled out so that one end of the tape is between the two clamping plates 23, and the two-way threaded rod 24 is driven to rotate by the motor 25 so that the two clamping plates 23 are close to each other to clamp one end of the tape, so that the pulled-out tape is located on one side of the copper wire, and the end of the tape is aligned with the lower pressure roller 19. When the defective position of the copper wire is found, the copper wire is continuously conveyed until the copper wire is completely damaged. The defective position is aligned with the pulled-out adhesive tape, and then the motor 3 20 is used to drive the rotating arm 18 to rotate, and the rotating arms 18 on the upper and lower sides can be rotated in different directions at the same time under the action of the two gears 21, so that the two pressure rollers 19 are close to the adhesive tape, and the pressure rollers 19 push the adhesive tape until the two pressure rollers 19 clamp the adhesive tape. At this time, the adhesive tape will be folded in half so that the adhesive layers are adhered together. At this time, the defective position of the copper wire is wrapped by the adhesive tape, and then the electric push rod 2 36 is used to drive the mounting block 40 to move, so that the adhesive tape is folded in half. The portion other than the strip is between the cutting plate 38 and the blade plate 39. At this time, the motor 7 41 drives the threaded rod 2 42 to rotate, so that the blade plate 39 can be moved closer to the cutting plate 38 until the blade on the blade plate 39 fits with the surface of one side of the cutting plate 38, and the adhesive tape can be cut, so that the adhesive tape is attached to the defective position of the copper wire. Then the blade plate 39 is reset, and the cut adhesive tape will fall again due to gravity. At the same time, the clamping plate 23 can be driven to rise, so that the broken end of the adhesive tape is again between the two clamping plates 23, and the clamping plate 23 is used to pull the adhesive tape again, and then the above operation is repeated, so that the defective position of the copper wire is attached with the adhesive tape. After the inspection work is completed, the worker can quickly locate the defective position of the copper wire by observing the position of the adhesive tape on the surface of the copper wire, thereby avoiding the subsequent repair of the defective position of the copper wire. Because the defective position of the copper wire is not obvious enough, it is difficult for the worker to accurately find the defective position, and then improper treatment or repair omission occurs, which is conducive to improving the repair efficiency of the defective position;

[0056] Although the above-mentioned method of attaching tape can be used to assist workers in finding the defective position of the copper wire, the defect is also divided into different degrees. Usually, when there are many defective positions, workers are required to first count the defective degrees of multiple defective positions of the copper wire, and then formulate a repair plan, which is conducive to improving the repair efficiency. If the tapes attached to the defective positions of the copper wire are relatively consistent, it is not conducive to the workers to count the defective degrees of the defective positions of the copper wire, thereby affecting the repair efficiency. Therefore, in order to avoid this situation, since the copper wire will pass through the inner cavity of the cylinder 29 during transportation, the tape attached to the surface of the copper wire will also pass through the inner cavity of the cylinder 29. When the tape is in the inner cavity of the cylinder 29, the electric push rod 45 belt The movable pressing block 47 moves, and the pressing part of the paint spray can 48 is squeezed by the pressing block 47, so that the paint is sprayed to the tape through the nozzle of the paint spray can 48, so that the tape is dyed, and a secondary mark can be formed on the tape. In addition, since each paint spray can 48 corresponds to a different color, the threaded rod 3 44 can be driven by the motor 8 50 to rotate, so that the threaded block 46 moves horizontally, and the position of the pressing block 47 is adjusted so that the pressing block 47 is aligned with the pressing parts of different paint spray cans 48, so that the tape is dyed into different colors, and different colors correspond to different degrees of defects. During the subsequent repair work, the workers can observe the color of the tape to count the degree of defects at each defective position, which is conducive to the workers to formulate a repair plan and improve the repair efficiency.

[0057] Furthermore, since the paint will splash when it is sprayed through the paint spray can 48, it is easy to cause the paint to adhere to the non-defective position of the copper wire, which is not conducive to the subsequent observation of the copper wire surface by the workers and is easy to cause confusion. Therefore, in order to avoid this situation, the shrink cloth 31 is in a stretched state in the initial state, and the copper wire can pass through the middle through hole of the shrink cloth 31 without contacting the shrink cloth 31. When the paint is sprayed, the motor 6 32 drives the threaded rod 1 33 to rotate, so that the adjustment ring 34 moves horizontally, and the multiple adjustment rods 30 move radially at the same time, so that the shrink cloth 31 The through hole in the middle of the cloth 31 shrinks until it contacts the copper wire. At this time, the painted tape is in a closed environment, and the paint sprayed from the paint spray can 48 will only be concentrated inside the cylinder 29, and will not splash around. This not only avoids the paint adhering to the non-defective position of the copper wire, which is not conducive to the subsequent observation of the surface of the copper wire by the workers, but also ensures the cleanliness of the working environment. In addition, when the copper wire is conveyed normally, the shrink cloth 31 is driven away from the copper wire, which avoids the paint adhering to the edge of the through hole of the shrink cloth 31 from adhering to the surface of the copper wire due to friction.

[0058] Working principle: The copper wire to be inspected for surface defects is wound around the unwinding roller 9, and then one end of the copper wire is pulled to pass through the through holes on the limit rods 5 on both sides, and then wound around the winding roller 3, and the copper wire is straightened, and then the motor 1 4 and the motor 2 10 are started at the same time, so that the winding roller 3 and the unwinding roller 9 rotate at the same time, and the copper wire can be transported. The limit rod 5 can limit the copper wire to prevent it from being offset during the transportation process. During the transportation of the copper wire, it will pass through the detection lens 49, and the detection lens 49 can detect the surface of the copper wire and display the detected picture on the display screen 11. The image displayed on the display screen 11 is usually clearer and more accurate than direct observation with the naked eye, so workers can more accurately judge the defects on the surface of the copper wire. In case of damage, the tape roll 14 is plugged into the installation roller 27, and one end of the tape wound on the surface of the tape roll 14 is pulled out so that one end of the tape is between the two clamping plates 23, and the two-way threaded rod 24 is driven to rotate by the motor four 25, so that the two clamping plates 23 are close to each other to clamp one end of the tape, so that the pulled-out tape is located on one side of the copper wire, and the end of the tape is aligned with the lower pressure roller 19. When the defective position of the copper wire is found, the copper wire is continued to be conveyed until its defective position is aligned with the pulled-out tape, and then the motor three 20 is used to drive the rotating arm 18 to rotate, and the rotating arms 18 on the upper and lower sides can be rotated in different directions at the same time under the action of the two gears 21, so that the two pressure rollers 19 are close to the tape, and the pressure rollers 19 push the tape until the two pressure rollers 19 clamp the tape. At this time , the adhesive tape will be folded in half so that the adhesive layers are adhered together. At this time, the defective position of the copper wire is wrapped by the adhesive tape, and then the electric push rod 2 36 is used to drive the mounting block 40 to move so that the portion of the adhesive tape other than the folded portion is between the cutting plate 38 and the blade plate 39. At this time, the motor 7 41 is used to drive the threaded rod 2 42 to rotate, so that the blade plate 39 can be moved close to the cutting plate 38 until the blade on the blade plate 39 fits with the surface of one side of the cutting plate 38, so that the adhesive tape can be cut and attached to the defective position of the copper wire. Then the blade plate 39 is reset, and the cut tape will fall again due to gravity. At the same time, the clamping plate 23 can be driven to rise so that the broken end of the adhesive tape is again between the two clamping plates 23, and the clamping plate 23 is used to pull the adhesive tape again, and then the above operation is repeated. After the inspection is completed, the worker can quickly locate the defective position of the copper wire by observing the position of the tape on the surface of the copper wire, thereby avoiding the situation that the worker is difficult to accurately find the defective position when repairing the defective position of the copper wire due to the lack of obviousness of the defective position of the copper wire, and then improper treatment or repair omission occurs, which is beneficial to improving the repair efficiency of the defective position. Since the copper wire passes through the inner cavity of the cylinder 29 during transportation, the tape attached to the surface of the copper wire will also pass through the inner cavity of the cylinder 29. When the tape is in the inner cavity of the cylinder 29, the electric push rod 45 can be used to drive the pressing block 47 to move, and the pressing block 47 is used to squeeze the pressing part of the paint spray can 48, so that the paint is sprayed to the tape through the nozzle of the paint spray can 48, so that the tape is dyed.A secondary mark can be formed on the tape, and since each paint can 48 corresponds to a different color, the motor 8 50 can be used to drive the threaded rod 3 44 to rotate, so that the threaded block 46 can be moved horizontally, and the position of the pressing block 47 can be adjusted to align the pressing portion of different paint cans 48, so that the tape can be dyed into different colors, and different colors correspond to different degrees of defect. During the subsequent repair work, the worker can observe the color of the tape to count the degree of defect at each defect position, which is beneficial for the worker to formulate a repair plan and improve the repair efficiency. In addition, the shrink cloth 31 in the initial state is in a stretched state, and the copper wire can pass through the through hole in the middle of the shrink cloth 31 without contacting the shrink cloth 31. When the paint is sprayed When the copper wire is out, the motor 6 32 drives the threaded rod 1 33 to rotate, so that the adjustment ring 34 moves horizontally, and the multiple adjustment rods 30 move radially at the same time, so that the through hole in the middle of the shrink cloth 31 is reduced until it contacts the copper wire. At this time, the painted tape is in a closed environment, and the paint sprayed by the paint spray can 48 will only be concentrated inside the cylinder 29, and will not splash to the surrounding area, which not only avoids the situation that the paint adheres to the non-defective position of the copper wire, which is not conducive to the subsequent observation of the copper wire surface by the workers, but also ensures the cleanliness of the working environment. In addition, when the copper wire is normally transported, the shrink cloth 31 is driven away from the copper wire, which avoids the situation that the paint adhered to the edge of the through hole of the shrink cloth 31 adheres to the copper wire surface due to friction.
