Description

Technical Field

[0001] This invention relates to the field of wire and cable manufacturing technology, specifically to a device and method for wrapping wire shielding and protective layers. Background Technology

[0002] In the manufacturing process of wires and cables, the wrapping of shielding and protective layers is a crucial step in ensuring stable wire performance. With the increasing demands for signal transmission quality from electronic devices, the accuracy and reliability of shielding layer wrapping have become paramount. Currently, the industry commonly uses wrapping machines for both shielding and protective layers. However, during the wrapping process, tin ash on the ground wire surface easily rubs against the shielding mold, generating tin powder that affects wrapping quality and product performance. Furthermore, the wrapping of the protective layer typically requires multiple layers to ensure protective effectiveness, but existing technologies lack effective adhesion methods, leading to the protective layer easily loosening or detaching.

[0003] Traditional equipment uses mechanical brushes or vacuum cleaners to remove solder dust from the surface of the ground wire. However, mechanical brushes may damage the surface of the ground wire, and vacuum cleaners cannot completely remove fine solder dust particles, thus affecting the wrapping quality. Summary of the Invention

[0004] To address the shortcomings of existing technologies, this invention provides a device and method for wrapping wire shielding and protective layers, which solves the problem of poor cleaning effect on wire surface impurities in existing devices.

A pull block is fixedly installed on the top surface of the inner frame. A pull rope is fixedly connected to the top surface of the pull block. A pull ring is fixedly connected to the top end of the pull rope.

[0006] Preferably, the rotating assembly includes an external gear ring, a gear post, a connecting belt, and a first motor. The external gear ring is fixedly disposed on one side of the inner ring, and one side of the external gear ring extends outside the fixed sleeve. The gear post is disposed on the top of the external gear ring and meshes with the external gear ring. The connecting belt is connected to the gear post through a pulley. The output end of the first motor is connected to the end of the connecting belt through a pulley.

[0007] Preferably, the outer surface of the fixed sleeve is provided with a first air inlet, and the first air inlet is connected to the end of the air supply pipe; the surface of the inner ring is provided with a second air inlet, and the port of the second air inlet is connected to the nozzle; and a cavity is provided between the second air inlet and the first air inlet.

[0008] Preferably, the outer side of the inner ring is fixedly connected to two fixed rings, and multiple rollers are rotatably installed inside the two fixed rings. The fixed sleeve has two raceways inside, and the rollers are arranged inside the raceways.

[0009] Preferably, two first fixed seats are fixedly installed on the top surface of the base, and an unwinding roller is installed between the two base fixed seats. Two second fixed seats are fixedly installed on the top surface of the base, and a winding roller is provided between the two second fixed seats. A second motor is fixedly installed on the outer surface of one of the two second fixed seats through a fixing frame, and the output end of the second motor is connected to the winding roller.

[0010] Preferably, a telescopic rod is symmetrically connected between the outer frame and the inner frame, and a telescopic spring is provided inside the telescopic rod, with the two ends of the telescopic spring connected to the inner rod and the outer rod of the telescopic rod, respectively.

[0011] Preferably, a method for wrapping a wire shielding layer and a protective layer includes the following steps: S1. Extend the wire body to the designated position: The wire body is composed of two core wires and two ground wires. The wire body is placed in the slot inside the guide groove. The surface of the ground wire is tinned copper, the surface of the core wire is covered with an insulation layer, and one end of it is extended into the interior of the soft-pack machine. S2. Clean the tin ash on the surface of the wire body: Turn on the air blowing device. The air blowing device blows high-pressure gas into the cavity between the inner ring and the fixed sleeve through the air supply pipe, and discharges through the second air supply port and nozzle, thereby blowing off the tin ash on the surface of the ground wire. S3. Perform soft wrapping on the wire body: Start the wrapping machine, wrap the shielding layer in a straight wrapping form on the outside of the wire body, and wrap the two protective layers in a wrapping form on the outside of the shielding layer. S4. Heat the solid adhesive to bond the protective layer to the shielding layer: The surface of the protective layer is covered with solid adhesive, and its end extends into the interior of the baking oven. When the baking oven is turned on, the solid adhesive melts and adheres to the shielding layer.

[0012] Working principle: When using this device, it can be placed in a designated position, and the wrapped wire body can be extended into the guide groove, the wrapping machine and the baking oven in sequence, and wound onto the outer surface of the take-up roller. The second motor is turned on, and the second motor drives the take-up roller to rotate, thereby conveying the wire body. During the conveying of the wire body, two sets of pressure rollers, two sets of first guide rollers and two sets of second guide rollers can increase the stability of the wire body conveying. During the transport of the wire body, the air blowing device is turned on, and the air blowing device blows high-pressure gas into the air supply pipe. Through the air supply pipe, the high-pressure gas can enter the cavity between the inner ring and the fixed sleeve. Then, the high-pressure gas enters the nozzle through the second air supply port. Finally, the nozzle can spray the high-pressure gas onto the surface of the wire body. After the high-pressure gas is sprayed out, the tin ash attached to the surface of the wire body can be blown off. When the first motor is turned on, it drives the toothed column to rotate via the connecting belt. The toothed column drives the outer toothed ring to rotate, which in turn drives the inner ring to rotate. The inner ring drives the nozzle to rotate, thereby adjusting the cleaning range of the nozzle on the wire body. When the inner ring rotates, it drives the extension ring to rotate, which in turn drives the mounting ring to rotate. The mounting ring drives the fan-shaped plate and the extension port to rotate, and the extension port can drive the cleaning brush on its inner side to sweep along the surface of the wire body, thereby cleaning the impurities attached to the surface of the wire body. The wrapping machine is started. First, the wrapping machine uses a direct wrapping method to attach the shielding layer to the surface of the wire body. After the shielding layer is attached, the wrapping machine can wrap two protective layers around the wire body. While the wire body is being continuously conveyed, the baking oven is turned on. The baking oven can heat the wire body. At this time, the solid glue between the protective layer and the shielding layer will melt, and then the protective layer and the shielding layer can be sealed and bonded.

[0013] This invention provides a device and method for wrapping a wire shielding layer and a protective layer. It has the following beneficial effects: 1. In this invention, an air blowing device is provided. The air blowing device can blow air into the air supply pipe. The high-pressure gas enters the cavity between the inner ring and the fixed sleeve, and then is discharged through the second air supply port by the nozzle. The air nozzle is directly facing the wire body, so the tin ash on the surface of the wire body can be blown off. By cooperating with the rotating component, the nozzle can be driven to rotate around the periphery of the wire body, thereby increasing the cleaning effect and ensuring the quality of the wrapping of the wire body.

[0014] 2. In this invention, when the rotating component drives the inner ring to rotate, the inner ring can drive the extension ring to rotate, the extension ring can drive the mounting ring fixedly installed on the inner side to rotate, the mounting ring drives the fan-shaped plate and the extension opening to rotate, and the extension opening drives the inner cleaning brush to sweep off the impurities stuck to the surface of the wire body, further enhancing the quality of the wrapping.

[0015] 3. In this invention, a pressure roller is installed on the inner side of the inner frame. The pressure roller presses on the top of the wire body inside the guide groove, thereby increasing the directionality and stability of the wire body wrapping. The telescopic spring inside the telescopic rod ensures that the pressure roller presses on the top of the wire body. At the same time, the telescopic spring has a certain buffering effect to prevent damage to the wire body. Attached Figure Description

[0018] The technical solution of the present invention will now be clearly and completely described with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of the present invention, and not all of them. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0019] Please see the appendix Figure 1 and attached Figure 4 The present invention provides a device for wrapping a wire shielding layer and a protective layer, including a base 1. A guide groove 5, a wrapping machine 4 and an oven 12 are sequentially fixedly installed on the top surface of the base 1. A fixing sleeve 7 is provided between the guide groove 5 and the wrapping machine 4, and the fixing sleeve 7 is fixedly installed on the outer surface of the wrapping machine 4 by a fixing rod 26. An inner ring 31 is movably installed inside the fixing sleeve 7. A nozzle 28 is installed on the inner side of the inner ring 31. An air blowing device 9 is installed on the top of the wrapping machine 4. The air blowing end of the air blowing device 9 is connected to an air supply pipe 8, and one end of the air supply pipe 8 is connected to the fixing sleeve 7. A rotating component is provided on one side of the inner ring 31.

[0020] Specifically, the jetting device of this apparatus is an air gun. The air outlet of the air gun is connected to the air supply pipe 8, and the high-pressure gas can be transmitted to the inside of the fixed sleeve 7 through the air supply pipe 8. The high-pressure gas entering the inside of the fixed sleeve 7 can be ejected outward through the nozzle 28. The spraying end of the nozzle 28 is directly facing the wire body 46 extending into the inside of the fixed sleeve 7. Therefore, the high-pressure gas can be sprayed in the direction of the wire body 46, thereby cleaning the solder adhering to the surface of the wire body 46 and ensuring the quality of the wrapping.

[0021] Please see the appendix Figure 3 and attached Figure 4The rotating assembly includes an outer toothed ring 30, a toothed column 21, a connecting belt 20, and a first motor 10. The outer toothed ring 30 is fixedly disposed on one side of the inner ring 31, and one side of the outer toothed ring 30 extends out of the outside of the fixing sleeve 7. The toothed column 21 is disposed on the top of the outer toothed ring 30, and the toothed column 21 is meshed with the outer toothed ring 30. The connecting belt 20 is connected to the toothed column 21 through a pulley. The output end of the first motor 10 is connected to the end of the connecting belt 20 through a pulley.

[0022] Specifically, the inner ring 31 is movably installed inside the fixed sleeve 7. Therefore, when the first motor 10 drives the connecting belt 20, the connecting belt 20 can drive the toothed column 21 to rotate on the outer toothed ring 30. Since the toothed column 21 and the outer toothed ring 30 are meshed, the outer toothed ring 30 can be driven to rotate. The outer toothed ring 30 can drive the inner ring 31 to rotate. The inner ring 31 can then drive the inner nozzle 28 to rotate. When the nozzle 28 sprays high-pressure gas outward, the area of ​​the wire body 46 can be increased by the nozzle 28 surrounding the wire body 46, thus increasing the cleaning effect.

[0023] Please see the appendix Figure 4 Appendix Figure 5 and attached Figure 6 The outer surface of the fixed sleeve 7 is provided with a first air inlet 29, and the first air inlet 29 is connected to the end of the air pipe 8. The surface of the inner ring 31 is provided with a second air inlet 32, and the port of the second air inlet 32 ​​is connected to the nozzle 28. A cavity is provided between the second air inlet 32 ​​and the first air inlet 29.

[0024] Specifically, the cavity between the first air inlet 29 and the second air inlet 32 ​​is located between the inner ring 31 and the fixed sleeve 7. Therefore, when the blowing device 9 is turned on, high-pressure gas can be transmitted through the air pipe 8 and the first air inlet 29 to the cavity between the inner ring 31 and the fixed sleeve 7. Then, the high-pressure gas can enter the interior of the nozzle 28 through the second air inlet 32, and then be sprayed out by the nozzle 28. The inner ring 31 is installed on the inner side of the fixed sleeve 7, which can ensure the sealing of the cavity between the inner ring 31 and the fixed sleeve 7, prevent the leakage of high-pressure gas, ensure the sealed channel of high-pressure gas, and also ensure the normal operation of cleaning the tin ash on the surface of the wire body 46.

[0025] Please see the appendix Figure 5 and attached Figure 6 Two fixed rings 33 are fixedly connected to the outer side of the inner ring 31. Multiple rollers 34 are rotatably installed inside the two fixed rings 33. Two raceways 35 are opened inside the fixed sleeve 7, and the rollers 34 are located inside the raceways 35.

[0026] Specifically, when the outer toothed ring 30 rotates and drives the inner ring 31 to rotate, the inner ring 31 can drive the fixed ring 33 fixedly connected to the outside to rotate. The fixed ring 33 can drive the roller 34 to roll in the raceway 35 opened inside the fixed sleeve 7. At the same time, the roller 34 is placed inside the raceway 35, which can limit the inner ring 31, thereby increasing the stability of the rotation of the inner ring 31 and indirectly increasing the stability of the nozzle 28 in cleaning the wire body 46.

[0027] Please see the appendix Figure 3 and attached Figure 7 An extension ring 22 is fixedly installed on one side of the inner ring 31, and the extension ring 22 extends out of the outer side of the fixing sleeve 7. An installation ring 36 is fixedly installed on the inner side of the extension ring 22 by fixing bolts 27. A fan-shaped plate 23 is fixedly connected to one side of the installation ring 36. An extension port 24 is fixedly connected to one side of the fan-shaped plate 23. Multiple cleaning brushes 25 are installed inside the extension port 24.

[0028] Specifically, the brush used in this device is a soft brush made of nylon. When the outer toothed ring 30 rotates, it drives the inner ring 31 to rotate. The inner ring 31 can drive the extension ring 22 to rotate. The extension ring 22 can drive the mounting ring 36 fixed on the inner side to rotate. The mounting ring 36 can drive the sector plate 23 to rotate. The sector plate 23 drives the extension port 24 to rotate. The extension port 24 can then drive the cleaning brush 25 on the inner side to rotate along the outer surface of the wire body 46 extending into the extension port 24. This allows the cleaning brush 25 to brush away impurities on the surface of the wire body 46, preventing impurities from adhering to the surface of the wire body 46 and affecting the subsequent wrapping quality. This further increases the cleaning effect on the wire body 46. Furthermore, by removing the fixing bolt 27, the fixing state of the mounting ring 36 can be released, and the sector plate 23 and the extension port 24 can be removed to allow for separate cleaning of the cleaning brush 25 on the inner side of the extension port 24 for subsequent use.

[0029] Please see the appendix Figure 1 and attached Figure 2 Two first fixed seats 2 are fixedly installed on the top surface of the base 1. A unwinding roller 3 is installed between the two base 1 fixed seats. Two second fixed seats 13 are fixedly installed on the top surface of the base 1. A winding roller 14 is provided between the two second fixed seats 13. A second motor 15 is fixedly installed on the outer surface of one of the two second fixed seats 13 through a fixed frame, and the output end of the second motor 15 is connected to the winding roller 14.

[0030] Specifically, the unwinding roller 3 is used to support the wire body 46. By turning on the second motor 15, the second motor 15 can drive the winding roller 14 to rotate. The rotation of the winding roller 14 can wind up the wrapped wire, thereby enabling stable wire transportation and stable winding operation.

[0031] Please see the appendix Figure 1 Appendix Figure 2 and attached Figure 10 A first fixing plate 11 is fixedly connected to one side of the wrapping machine 4. Two first guide rollers 17 for guiding the wire body 46 are installed on one side of the first fixing plate 11. A second fixing plate 18 is fixedly installed on one side of the baking oven 12. Two second guide rollers 19 are installed on one side of the second fixing plate 18. A shielding layer 45 is wrapped around the outside of the wire body 46. A protective layer 43 is wrapped around the outside of the shielding layer 45. Solid glue 44 is provided between the protective layer 43 and the shielding layer 45.

[0032] Specifically, the wire body 46 consists of two core wires and two ground wires. The shielding layer 45 is a shielding film containing carbon nanotubes as a polymer material for anti-interference and signal shielding. The protective layer 43 is made of polyester tape to enhance insulation performance. The shielding layer 45 and the protective layer 43 are wrapped in different ways: the shielding layer 45 is wrapped directly, while the two protective layers 43 are wrapped around the wire. This combination of direct and wrapping increases the tightness of the wrapping and improves the wire's tensile and bending resistance. A solid adhesive 44 is placed between the protective layer 43 and the shielding layer 45. When the wire body 46 extends into the oven 12, the oven 12 can bake and heat the wire body 46. The heat is transferred to the inside of the wire body 46, which melts the solid glue 44. This allows the protective layer 43 to be tightly adhered to the outer wall of the shielding layer 45 by the solid glue 44, further increasing the quality of the wire body 46 wrapping. The first guide roller 17 and the second guide roller 19 can guide the wire body 46 during transportation, preventing the wire body 46 from deviating during winding or wrapping, and further increasing the stability of the wire body 46 transportation.

[0033] Please see the appendix Figure 8 Two outer frames 6 are fixedly installed on the top surface of the guide groove 5. An inner frame 40 is provided on the inner side of the outer frame 6. A pressure roller 41 is rotatably installed on the inner side of the inner frame 40. A pull block 37 is fixedly installed on the top surface of the inner frame 40. A pull rope 38 is fixedly connected to the top surface of the pull block 37. A pull ring 16 is fixedly connected to the top end of the pull rope 38.

[0034] Specifically, the top surface of the guide groove 5 has a slot for the power supply cable body 46 to pass through, and the bottom of the pressure roller 41 extends into the inner side of the slot. When the cable body 46 is conveyed, the pressure roller 41 can press on the top surface of the cable body 46. The pressure roller 41 is rotatably installed inside the inner frame 40. Therefore, when the cable body 46 is conveyed, the pressure roller 41 can roll on the top of the cable body 46. The pressure roller 41 is made of rubber, and its soft and malleable properties can prevent excessive pressure from damaging the cable body 46. When the cable body 46 is conveyed and the pressure roller 41 rolls on its top, it can prevent the cable body 46 from shifting during the conveying process. At the same time, it can stabilize the tension of the cable body 46 during the winding process, ensuring the stability of the cable body 46 during the conveying process.

[0035] Please see the appendix Figure 9 A telescopic rod 39 is symmetrically connected between the outer frame 6 and the inner frame 40. The telescopic rod 39 is equipped with a telescopic spring 42 inside, and the two ends of the telescopic spring 42 are respectively connected to the inner rod and the outer rod of the telescopic rod 39.

[0036] Specifically, the elastic potential energy of the telescopic spring 42 can always apply downward pressure to the inner rod of the telescopic rod 39, thereby ensuring that the pressure roller 41 presses against the moving part of the wire body 46. At the same time, the elastic potential energy of the telescopic spring 42 can buffer the pressure of the pressure roller 41, preventing excessive pressure from damaging the wire body 46. By pulling the pull ring 16, the pull ring 16 pulls the pull rope 38, the pull rope 38 pulls the pull block 37, and the pull block 37 pulls the inner frame 40 upward. The inner frame 40 can drive the pressure roller 41 upward, which facilitates the extension of the wire body 46 from the slot at the top of the guide groove 5.

[0037] Please see the appendix Figure 1 -Appendix Figure 11 A method for wrapping a wire shielding layer and a protective layer, the method comprising the following steps: S1. Extend the wire body 46 to the designated position: The wire body 46 is composed of two core wires and two ground wires. The wire body 46 is placed in the slot inside the guide groove 5. The surface of the ground wire is tinned copper, the surface of the core wire is covered with an insulation layer, and one end of it is extended into the interior of the soft-pack machine. S2. Clean the tin ash on the surface of the wire body 46: Turn on the air blowing device 9. The air blowing device 9 blows high-pressure gas into the cavity between the inner ring 31 and the fixed sleeve 7 through the air supply pipe 8, and discharges it through the second air supply port 32 and the nozzle 28, thereby blowing off the tin ash on the surface of the ground wire. S3. Perform soft wrapping on the wire body 46: Start the wrapping machine 4, and wrap the shielding layer 45 in a straight wrapping form on the outside of the wire body 46. Wrap the two protective layers 43 in a wrapping form on the outside of the shielding layer 45. S4. Heat the solid adhesive 44 to bond the protective layer 43 to the shielding layer 45: The surface of the protective layer 43 is provided with solid adhesive 44, and its end extends into the interior of the baking oven 12. When the baking oven 12 is opened, the solid adhesive 44 melts and adheres to the shielding layer 45.

[0038] Although embodiments of the invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the invention, the scope of which is defined by the appended claims and their equivalents.
