Description

Technical Field

[0001] The invention relates to the technical field of cable outer conductor molding, in particular to a radio frequency coaxial cable outer conductor trimming welding molding device. Background Art

[0002] Radio frequency cable is a cable that transmits electromagnetic energy within the radio frequency range. Radio frequency cable is an indispensable component in various radio communication systems and electronic equipment, and is widely used in wireless communication, broadcasting, television, radar, navigation, computers and instruments. In the production process of coaxial cable, it is necessary to form the outer conductor on the cable. The outer conductor is formed from a strip into a ring and wrapped on the cable structure to realize the forming of the outer conductor of the coaxial cable. Since the outer conductor is made of copper strip, the original edge of the copper strip is easy to oxidize, the actual width changes, the edge quality is poor, and the edge quality consistency is poor, which affects the welding quality. Therefore, before the outer conductor is formed, it is necessary to perform edge trimming. At present, mechanical, horizontal, or vertical edge trimming cutters are used for edge trimming of the outer conductor, which has low precision and is easy to squeeze the outer conductor out of shape, affecting the forming quality; secondly, after the two sides of the outer conductor are contacted and formed into a ring, the contact positions of the two sides need to be welded. Due to the errors in edge trimming and the transmission errors of the outer conductor, the welding position of the outer conductor and the welding position of the welding machine will deviate, resulting in welding offset, affecting the welding effect, and then affecting the forming quality of the outer conductor.

DETAILED DESCRIPTION

[0028] The technical solution of the present invention is further described in detail below in conjunction with the accompanying drawings, but the protection scope of the present invention is not limited to the following.

[0029] Embodiment 1

[0030] like Figures 1 to 9As shown, a radio frequency coaxial cable outer conductor trimming welding forming device comprises a wrapping mechanism, a laser trimming mechanism, an outer conductor forming mechanism, a welding mechanism, an imaging detection mechanism, a repair welding mechanism and an edge grinding mechanism which are sequentially arranged along the conveying direction of the inner conductor, the wrapping mechanism is used to sequentially wind an insulating layer and a heat insulating layer on the inner conductor, the laser trimming mechanism comprises a fixed guide component, an anti-deflection detection component and two groups of laser cutting machines 1, the anti-deflection detection component and the fixed guide component are spaced apart along the conveying direction of the inner conductor, the anti-deflection detection component comprises a U-shaped detection seat 2, an upper anti-deflection roller 3 and a lower anti-deflection roller 4 are rotatably arranged in the U-shaped detection seat 2, the fixed guide component comprises a U-shaped fixed seat 5, an upper guide roller 6 and a lower guide roller 7 are rotatably arranged in the U-shaped fixed seat 5, and the two groups of laser cutting machines 1 are arranged vertically. The two laser cutting machines 1 are arranged perpendicular to the conveying direction of the inner conductor, and the two groups of laser cutting machines 1 are respectively used for trimming the two sides of the outer conductor belt. The outer conductor forming mechanism includes a forming mold 8 and a shaping mold 9 arranged in sequence along the conveying direction of the inner conductor. The forming mold 8 is provided with a tapered hole 10 and a forming circular hole 11 in sequence along the conveying direction of the inner conductor. The small diameter end of the tapered hole 10 is connected to the forming circular hole 11. The shaping mold 9 is provided with a shaping hole 12 through the conveying direction of the inner conductor. The welding mechanism welds the two sides of the outer conductor belt together, and then detects the welding condition through the imaging detection mechanism. If there is insufficient welding, the repair welding mechanism is used for repair welding. The burrs caused by the repair welding are polished smooth by the grinding mechanism. The traditional coaxial cable structure generally consists of an inner conductor, an insulating layer, an outer conductor and an outer sheath. In the present invention, the traditional mechanical edge cutting is changed to laser edge cutting, so that the cutting position of the outer conductor has a higher temperature, which leads to that when the outer conductor is molded on the insulating layer, the insulating layer or the inner conductor is easily damaged, thereby affecting the performance of the inner conductor. For this reason, the coaxial cable of the present invention adds a heat insulation layer for heat insulation protection of the insulating layer and the inner conductor. The specific molding process is: the inner conductor is paid out through the pay-off frame, and the molded cable is wound up by the take-up frame to realize the continuous transportation of the inner conductor. The inner conductor is first transported to the wrapping mechanism for wrapping processing. The wrapping mechanism is provided with two groups along the conveying direction of the inner conductor, and the insulating layer and the heat insulation layer are wound on the inner conductor in turn. At the same time, the outer conductor tape is paid out from the outer conductor take-up frame, and the inner conductor is transported on the upper surface of the outer conductor tape. The outer conductor tape is firstly subjected to laser cutting. The edge mechanism performs edge trimming processing, the outer conductor tape first passes between the upper anti-deflection roller 3 and the lower anti-deflection roller 4, and then passes between the upper guide roller 6 and the lower guide roller 7. The outer conductor tape is stretched and conveyed through the anti-deflection detection component and the fixed guide component, so that the laser cutting machine 1 can accurately perform edge trimming processing on the side of the outer conductor tape, and the high energy density laser beam of the laser cutting machine 1 is used to cut the outer conductor material, replacing the original mechanical, horizontal or vertical edge trimming cutter, which has the advantages of narrow incision width (less tape waste), high precision, small heat-affected zone, and can effectively avoid material deformation, improve the dimensional accuracy and edge quality of the outer conductor. The outer conductor tape that has been processed by edge trimming is conveyed to the outer conductor forming mechanism, and the outer conductor tape passes through the tapered hole 10, the forming circular hole 11 and the shaping hole 12 in turn.The outer conductor strip is gradually gathered into a ring shape through the tapered hole 10, so that the outer conductor is wrapped on the heat insulation layer, and the forming circular hole 11 and the shaping hole 12 match the outer diameter of the outer conductor after forming, so that the forming state of the outer conductor strip can be shaped. The welding mechanism is arranged between the forming mold 8 and the shaping mold 9. The welding mechanism includes a welding frame 26 and a welding device 27. The welding device 27 is installed on the welding frame 26. The two sides of the outer conductor strip that are gathered are welded together by the welding device 27. This belongs to the prior art and will not be repeated here. Due to the existence of errors, there will be a deviation between the welding position of the welding mechanism and the welding position of the outer conductor strip, resulting in soldering on the surface of the outer conductor strip, leaking welding, and bulging on the surface of the outer conductor strip. For this reason, the welding condition is visually inspected by an imaging detection mechanism. The imaging detection machine The structure includes a detection frame 28 and an industrial camera 29. The industrial camera 29 is installed on the detection frame 28. The welding situation is imaged and fed back by the industrial camera 29, thereby judging the welding situation of the outer conductor. Visual imaging belongs to the prior art, and the specific imaging detection principle is no longer repeated. When the welding offset is detected, the repair welding mechanism starts to repair the leaking position, thereby eliminating the leaking situation and improving the welding quality. Due to the problem of welding offset, the surface of the outer conductor is not smooth, resulting in bulging when the outer sheath is installed. Therefore, the surface of the formed outer conductor is polished by the edge grinding mechanism to make the surface of the outer conductor smooth, eliminating the production problem of cable bulging, so that the outer conductor can be well formed on the thermal insulation layer, which has the advantages of high forming efficiency, low scrap rate and high precision.

[0031] Embodiment 2

[0032] Based on the first embodiment, Figure 1 , Figures 7 to 9As shown, the wrapping mechanism includes a wrapping frame 47, a wrapping wheel 48 and a tape reel 49. The wrapping wheel 48 is rotatably mounted on the wrapping frame 47. The wrapping wheel 48 is provided with a circular hole 50 for the inner conductor to pass through. The wrapping wheel 48 is provided with a wrapping outer gear ring 51. A wrapping gear 52 is rotatably provided on the wrapping frame 47. The wrapping gear 52 meshes with the wrapping outer gear ring 51. A wrapping motor 53 is installed on the wrapping frame 47. The output shaft of the wrapping motor 53 is connected to the wrapping gear 52. A mounting shaft 54 ​​is fixed on the wrapping wheel 48. The tape reel 49 is movably mounted on the mounting shaft 54. The insulating layer and the The thermal insulation layer is wound on the tape reel 49 of different winding mechanisms, and the insulation layer and the thermal insulation layer have the same winding direction. To avoid redundancy, taking the thermal insulation layer as an example, one end of the thermal insulation tape is wound on the insulation layer, and the winding motor 53 drives the winding gear 52 to rotate. The winding gear 52 drives the winding wheel 48 to rotate by engaging with the winding outer gear ring 51. The winding wheel 48 drives the tape reel 49 to wind around the inner conductor. In conjunction with the transportation of the inner conductor, the thermal insulation layer is wound on the insulation layer in a spiral manner, thereby winding a layer of thermal insulation on the insulation layer to protect the insulation layer and the inner conductor from being affected by the high temperature of the cutting edge of the outer conductor.

[0033] Embodiment 3

[0034] The material belt of the traditional wrapping machine is in a loose state, resulting in the insulation layer being unable to be tightly wound on the thermal insulation layer, and the thermal insulation layer being unable to be tightly wound on the insulation layer. The loosely wound insulation layer and the thermal insulation layer will cause the produced cable to have bulging, inability to be fully insulated, and inability to be fully insulated. For this reason, based on the second embodiment, as Figures 7 to 9As shown, a limiting mechanism is provided at one end of the mounting shaft 54 ​​away from the wrapping rotating wheel 48, and the limiting mechanism includes a friction pressure ring 55, a limiting spring 56 and a mounting disk 57. The two ends of the limiting spring 56 are respectively connected to the friction pressure ring 55 and the mounting disk 57, and a threaded column 58 is fixed to one end of the mounting disk 57 close to the friction pressure ring 55. A threaded hole is provided at one end of the mounting shaft 54 ​​away from the wrapping rotating wheel 48, and the threaded column 58 is threadedly adapted in the threaded hole. The friction pressure ring 55 is sleeved on the mounting shaft 54 ​​and pressed against the belt reel 49. The belt reel 49 is an annular structure, which is convenient for installation and disassembly. When installing, the limiting mechanism is first removed, and then the belt reel 49 is sleeved on the mounting shaft 54, and then the limiting mechanism is installed. Through the cooperation of the threaded column 58 and the threaded hole, the mounting disk 57 is installed on the mounting shaft 54, so that the friction pressure The ring 55 contacts the tape reel 49. At this time, the limit spring 56 is in a compressed state. Under the reaction force of the limit spring 56, the friction pressure ring 55 is pressed against the tape reel 49. The end face of the friction pressure ring 55 close to the tape reel 49 is friction-treated or a rubber pad is arranged, so that the tape reel 49 is pressed between the winding wheel 48 and the friction pressure ring 55. There is a large friction force between the friction pressure ring 55 and the tape reel 49, so that the tape reel 49 will not automatically deflect to release the insulating layer and the thermal insulation layer. It is necessary to pull the tape reel 49 to overcome the friction force and rotate it during the winding process to release the insulating layer and the thermal insulation layer, so that the insulating layer and the thermal insulation layer are in a taut state for winding, so that the insulating layer can be tightly wound on the inner conductor and the thermal insulation layer can be tightly wound on the insulating layer, which has a better winding effect and improves the production quality of the cable.

[0035] Embodiment 4

[0036] Based on the third embodiment, Figures 1 to 6As shown, the anti-bias detection component also includes two groups of anti-bias detection components, which are arranged at both ends of the U-shaped detection seat 2. The anti-bias detection component includes a pressure sheet 13, a pressure plate 14, a pressure plate 15 and a pressure sensor 16. One end of the pressure sheet 13 is located between the upper anti-bias roller 3 and the lower anti-bias roller 4, and the other end moves through the U-shaped detection seat 2 to connect the pressure plate 14. The pressure plate 14 is connected to the pressure plate 15 through a spring 17. The pressure plate 15 is connected to the pressure shaft of the pressure sensor 16. The pressure sensor 16 is installed on the U-shaped detection seat 2 through an L-shaped mounting seat 19. The measuring assembly also includes a mounting platform 18, the U-shaped detecting seat 2 and the U-shaped fixing seat 5 are both fixed on the mounting platform 18, and an annular limiting groove 20 is provided on the upper guide roller 6 and the lower guide roller 7. In specific implementation, the outer conductor winding frame has the freedom to move in a direction perpendicular to the conveying direction of the inner conductor, and the outer conductor winding frame is pushed to move by adjusting the cylinder. The thickness of the pressure sheet 13 is less than the thickness of the outer conductor belt, so that the pressure sheet 13 can be suspended and arranged between the upper anti-deflection roller 3 and the lower anti-deflection roller 4, eliminating the influence of friction on the movement of the pressure sheet 13, and the pressure sheets 13 of the two sets of anti-deflection detecting assemblies contact the outer conductor belt respectively. On both sides, affected by the conveying error of the outer conductor belt, or the outer conductor belt is not neatly rolled up on the outer conductor winding frame, the outer conductor conveying deviation will be caused. When the outer conductor belt is deviated, the outer conductor will squeeze the pressure sheet 13 in the deviating direction, the pressure sheet 13 squeezes the pressure plate 14, the pressure plate 14 squeezes the spring 17, and the reaction force of the spring 17 causes the pressure plate 15 to squeeze the pressure sensor 16. The pressure signal of the pressure sensor 16 is used to judge whether the outer conductor belt is deviated and the direction of the deviation. When the pressure value of one of the pressure sensors 16 reaches the set value, it indicates that the outer conductor belt is The outer conductor tape is offset toward the arrangement direction of the pressure sensor 16. At this time, the adjusting cylinder pushes the outer conductor winding frame to move away from the pressure sensor 16, thereby fine-tuning the conveying direction of the outer conductor tape, so that the outer conductor tape can enter the annular limit groove 20 in an unextruded state, and the position of the outer conductor tape is positioned by the annular limit groove 20. The laser cutting machine 1 is arranged at the output end of the fixed guide component, so that the laser cutting machine 1 can accurately complete the edge trimming of the outer conductor tape and adjust the conveying position of the outer conductor tape to prevent it from offsetting, so that the outer conductor tape will not squeeze the end of the annular limit groove 20 to cause deformation.

[0037] Embodiment 5

[0038] Based on the fourth embodiment, Figures 1 to 6As shown, the outer conductor forming mechanism also includes a plurality of auxiliary forming components, which are arranged between the fixed guide component and the forming die 8. The plurality of auxiliary forming components are arranged at intervals along the conveying direction of the inner conductor. The auxiliary forming components include an auxiliary forming frame 25, an auxiliary ball 23 and an arc plate 24. Two auxiliary forming frames 25 are arranged at intervals perpendicular to the conveying direction of the inner conductor. The auxiliary ball 23 is rotatably mounted on the auxiliary forming frame 25. The arc plate 24 is fixed on the auxiliary forming frame 25 and is located below the auxiliary ball 23. The outer conductor strip passes between the auxiliary ball 23 and the arc plate 24. The curvature of the arc plate 24 in the plurality of auxiliary forming components is The curvature of the outer conductor belt after molding is gradually approached along the direction approaching the molding die 8, and the two side edges of the outer conductor belt pass through between the auxiliary balls 23 and the arc plates 24 of the two auxiliary molding frames 25 respectively. The outer conductor belt is bent and gathered through the cooperation of the auxiliary balls 23 and the arc plates 24. Since the curvature of the arc plates 24 in the multiple auxiliary molding components gradually approaches the curvature of the outer conductor belt after molding along the direction approaching the molding die 8, the inner conductor belt is gradually bent and gathered, so that the inner conductor belt can smoothly penetrate into the tapered hole 10 for plasticity, avoiding the problem of deformation of the inner conductor belt caused by direct large-scale bending, so that the outer conductor belt can be well formed into a ring shape.

[0039] Embodiment 6

[0040] Based on Example 5, Figures 1 to 6As shown, the repair welding mechanism includes a driving welding ring 30, a welding machine 31 and a tooling plate 32. The tooling plate 32 is provided with a mounting hole along the conveying direction of the inner conductor. The driving welding ring 30 is rotatably installed in the mounting hole through a bearing. An outer gear ring 33 is sleeved on the driving welding ring 30. A pinion 35 is rotatably provided on the tooling plate 32. The pinion 35 meshes with the outer gear ring 33. A driving motor 34 is installed on the tooling plate 32. The output shaft of the driving motor 34 is connected to the pinion 35. The welding machine 31 is installed on the driving welding ring 30. Due to the existence of errors, the outer conductor strip will be offset at the outer conductor forming mechanism, that is, the welding positions on both sides of the outer conductor strip are deflected and displaced, resulting in the partial position of the outer conductor strip not being welded together. For this reason, the repair welding mechanism is used for repairing. When the imaging detection mechanism detects a leak, except for the repair welding mechanism, other mechanisms stop running. Since it is difficult for the imaging detection mechanism to accurately calculate the offset of the leak, it can only detect the offset direction and approximate offset of the welding position equivalent to the welding machine 31. For this reason, the driving motor 34 drives the driving welding ring 30 to deflect through the engagement of the pinion 35 and the outer gear ring 33, and the driving welding ring 30 drives the welding machine 31 to deflect close to the actual welding position of the outer conductor belt. During the process, the welding machine 31 performs a welding action, so that the welding machine 31 welds on the outer conductor belt in an arc line, so that the welding route covers the actual welding position, and completes the welding operation of the leak position of the outer conductor belt, so that the outer conductor belt can achieve comprehensive welding operations and improve the forming quality of the outer conductor.

[0041] Embodiment 7

[0042] Since the welding device 27 is not accurately welded to the side of the outer conductor belt, solder will remain on the surface of the outer conductor belt. At the same time, the arc welding line of the welding machine 31 will also leave solder on the surface of the outer conductor belt, resulting in an uneven surface of the outer conductor, causing the produced cable to have a bulging problem. Therefore, based on the sixth embodiment, as shown in FIG. Figure 1 , Figure 5 and Figure 6As shown, the edge grinding mechanism includes an edge grinding tooling plate 36, a driving pulley 37, a driven pulley 38 and a grinding belt 39. The edge grinding tooling plate 36 is provided with an edge grinding hole 40 for the inner conductor to pass through. The driving pulley 37 is rotatably installed below the edge grinding hole 40. The driving pulley 37 has the freedom to move along the radial direction of the edge grinding hole 40. The left and right sides of the edge grinding hole 40 are rotatably provided with driven pulleys 38. The driven pulley 38 has the freedom to deflect around the circumferential direction of the edge grinding hole 40. The grinding belt 39 is sleeved on the driving pulley 37 and the driven pulley 38. Under normal conditions, the grinding belt 39 is located above the outer conductor and does not contact the outer conductor, so that the grinding belt 39 does not affect the outer conductor. The outer conductor is transported by the edge grinding mechanism for polishing after the repair welding is completed. During the polishing process, the inner conductor and the outer conductor are stopped, and then the driving pulley 37 moves downward. Since the length of the polishing belt 39 is fixed, the driving pulley 37 will pull the driven pulley 38 downward through the polishing belt 39, so that the driven pulley 38 moves to the bottom of the outer conductor, so that the polishing belt 39 contacts the upper surface of the outer conductor, and the polishing belt 39 is driven to rotate by the driving pulley 37 to run. The running polishing belt 39 polishes the upper surface of the outer conductor to avoid bulging problems in cables produced later.

A grinding motor is installed at the end of the active slider 42 away from the active pulley 37, and the output shaft of the grinding motor is connected to the active pulley 37. A cylinder 43 is installed in the vertical slide groove 41, and the output shaft of the cylinder 43 is connected to the active slider 42. The edge grinding tooling plate 36 is provided with arc-shaped slide grooves 44 on both sides of the edge grinding circular hole 40, and the arc-shaped slide groove 44 is coaxially arranged with the edge grinding circular hole 40. A moving wheel 45 is slidably adapted in the arc-shaped slide groove 44, and the driven pulley 38 is rotatably mounted on the moving wheel 45. A tension spring 46 is arranged in the arc-shaped slide groove 44, and one end of the tension spring 46 is connected to one end of the arc-shaped slide groove 44, and the other end is connected The moving wheel 45 drives the active slider 42 to move up and down through the cylinder 43. The active slider 42 pulls the moving wheel 45 to move in the arc-shaped slide groove 44 through the polishing belt 39, so that the driven pulley 38 moves in an arc shape, so that the driven pulley 38 can move to the bottom of the outer conductor, and at the same time, the distance between the two driven pulleys 38 can be changed, so that the driven pulley 38 can smoothly move to adjust the contact state of the polishing belt 39 and the outer conductor. At the same time, by adjusting the downward position of the driven pulley 38, the contact area of ​​the polishing belt 39 and the outer conductor can be adjusted, so that the polishing belt 39 can fully cover the welding path of the repair welding, and realize the comprehensive polishing of the welding path. When the active pulley 37 is reset by the reaction force of the tension spring 46, the driven pulley 38 can also be reset. At the same time, the tension spring 46 keeps the polishing belt 39 in a tensioned state at all times, which has a better polishing effect.
