Detailed Description

In order to better understand the technical solutions of the present invention, the present invention will be further described in detail with reference to fig. 1 to 12.

Referring to fig. 1, an embodiment of the present invention provides a cable manufacturing method, which is based on a cable manufacturing apparatus, the cable manufacturing apparatus includes a cable production mechanism, a cable detection mechanism, and a cable winding mechanism, the cable manufacturing method includes the following steps:

101. the cable production mechanism is used for drawing a metal core, twisting a wire core, and then manufacturing an insulating layer on the wire core; specifically, common materials for manufacturing wire cores, such as copper and aluminum, are firstly subjected to annealing treatment on copper and aluminum monofilaments at normal temperature through one or a plurality of die holes of a stretching die by using a wire drawing machine to reduce the cross section, increase the length and improve the strength of the monofilaments, so that the toughness of the monofilaments is improved, and the strength of the monofilaments is reduced; twisting the monofilaments into a wire core to improve the softness of the cable, so that the cable is convenient to lay and install; an extruder is then used to make the insulation of the core.

102. The cable detection mechanism is used for detecting the cable wrapped by the insulating layer so as to remove the cable with bad points; specifically, the spark tester 10 is used to load the set voltage value onto the cable wrapping the insulating layer periodically according to a certain rule, and the conductor part is grounded, so that a voltage difference is formed between the conductor and the insulating surface, thereby detecting whether the insulating layer is bad, and if a bad point appears on the cable, the spark tester 10 alarms to transmit a signal to the control center, so that the cable production line is stopped, and the cable with the bad point is processed.

103. A cable winding mechanism for winding the cable which is detected to have no bad points into bundles; specifically, a winding machine is used for winding the cable without bad points into bundles.

Referring to fig. 2 to 12, another embodiment of the present invention provides a cable manufacturing apparatus, including a cable production mechanism, a cable detection mechanism and a cable winding mechanism that are sequentially disposed, where the cable detection mechanism includes a frame 1 and a spark tester 10 disposed on the frame 1, and further includes: the cable re-detection mechanism 2 comprises a limiting piece 20, a wire pulling wheel 21, a first wire winding roller 22 and a second wire winding roller 23 with variable radial sizes; when the spark tester 10 detects a defective point on the cable, the first winding roller 22 and the second winding roller 23 are both thinned to release the wound cable, and the limiting piece 20 limits the cable from entering the spark tester 10 and limits the cable released by the first winding roller 22 from moving to the cable winding mechanism; the wire pulling wheel 21 is moved by a first driving member 25 to drive the wire released by the first wire winding roller 22 to retract to the spark tester 10 for detection, and the wire released by the second wire winding roller 23 is wound by the wire winding mechanism.

Specifically, the limiting member 20 limits the moving cable based on the alarm signal of the spark tester 10, and the radial dimensions of the first winding roller 22 and the second winding roller 23 can be changed, that is, when the cable starts to be spirally wound on the surface of the cable for a plurality of turns from one end of the first winding roller 22, the cable extends from the other end of the first winding roller 22, and when the cable extends from the end of the second winding roller 23 corresponding to the other end of the first winding roller 22 to be spirally wound on the surface of the cable for a plurality of turns from the other end of the second winding roller 23 corresponding to the one end of the first winding roller 22, the cable extends from the other end of the second winding roller 23 corresponding to the one end of the first winding roller 22, and is wound on the first winding roller 22 and the second winding roller 23.

Since the entry and exit points of the cables on the first winding roller 22 and the second winding roller 23 are fixed, the number of winding turns of the cables does not change when the first winding roller 22 and the second winding roller 23 change in size, that is, when the radial size of the first winding roller 22 or the second winding roller 23 becomes larger, the number of winding turns of the cables does not change, but the required whole cable length increases, so that a part of the length of the cables needs to be wound from another place, when the radial size of the first winding roller 22 or the second winding roller 23 becomes smaller, the number of winding turns of the cables does not change, but the required whole cable length decreases, a part of the cables originally wound on the first winding roller 22 or the second winding roller 23 is increased, and if the cables are normally wound on the first winding roller 22 or the second winding roller 23, a part of the length of the cables can be pulled away from the first winding roller 22 or the second winding roller 23 by external force;

the radial dimensions of the first wire winding roller 22 and the second wire winding roller 23 can be changed, for example, a screw rod 221 is rotatably arranged in the roller body 220, two wire blocks 222 are screwed on the screw rod 221, the screw threads on the two wire blocks 222 are rotated in opposite directions, namely, when the screw rod 221 rotates in one direction, the two wire blocks 222 can move in opposite directions, then, a plurality of arc-shaped plate bodies 223 are arranged in parallel in the circumferential direction on the roller body 220, the length direction of the plate bodies 223 is axially parallel to the roller body 220 and can slide in the radial direction, a push-pull rod 224 is hinged between each wire block 222 and each plate body 223 together, specifically, when a driving source is adopted to drive the screw rod 221 to rotate, if the two wire blocks 222 on the screw rod 221 are close to each other, each wire block 222 pushes the plate body 223 to move in the direction away from the central line of the roller body 220 through the connected push-pull rod 224, so that the radial dimension of the second wire winding roller 23 of the first wire winding roller 22 can be increased, and conversely, the radial dimension of the second wire winding roller 23 of the first wire winding roller 22 can be decreased can be realized.

When the cable passing through the cable winding mechanism detected by the spark tester 10 has a bad point, the cable with the bad point is wound on the first winding roller 22 through the spark tester 10 as the cable production line is not stopped, then the first winding roller 22 and the second winding roller 23 are simultaneously reduced in radial dimension, the lengths of the cables wound on the first winding roller 22 and the second winding roller are increased by a part, meanwhile, the limiting piece 20 immediately limits the cable to enter the spark tester 10 and limits the cable released by the first winding roller 22 to move towards the cable winding mechanism, then the first driving piece 25 drives the wire pulling wheel 21 to pull the cable to move reversely, so that the cable with the bad point, which is wound on the first winding roller 22, passes through the spark tester 10 again for secondary detection, and if the spark tester 10 still alarms, the cable production line is stopped entirely so as to process the cable with the bad point at the part; if the spark tester 10 does not give an alarm, the limiting piece 20 removes the limitation of the cable, the radial dimension of the first winding roller 22 and the second winding roller 23 also become larger, the cable which passes through the spark tester 10 again in the reverse direction before passes through the spark tester 10 for the third time (the moving direction of the cable is the same as that when the cable passes through the spark tester 10 for the first time), if the spark tester 10 gives an alarm, the whole cable production line is stopped so as to process the cable with the bad point in the part, and if the cable does not give an alarm again, the cable production line works normally.

In this embodiment, by setting the limiting member 20, when a defective point exists on the cable at the detection position of the spark testing machine 10, the cable conveyed by the cable production mechanism cannot enter the spark testing machine 10, the cable released by the thickness of the second winding roller 23 can be temporarily wound by the cable winding mechanism, the cable released by the thickness of the first winding roller 22 is retracted to the spark testing machine 10 for detection again under the driving of the wire pulling wheel 21, and during this period, the cable production mechanism and the cable winding mechanism are not stopped, and the cable winding mechanism does not need to rotate, so that the purpose of detecting again by retracting the cable can be achieved.

Preferably, the frame 1 is provided with a first wire guiding wheel 11, and a wire winding wheel 24 is arranged between the first wire guiding wheel 11 and the limiting piece 20; when the limiting member 20 limits the cable from entering the spark tester 10, the take-up pulley 24 is moved by the first driving member 25 to straighten the cable conveyed by the cable producing mechanism.

Specifically, the first wire guiding wheel 11 guides the wire conveyed by the wire producing mechanism to the wire winding wheel 24, the wire winding wheel 24 guides the wire to the limiting piece 20, when the limiting piece 20 limits the wire to enter the spark testing machine 10, the wire conveyed by the wire producing mechanism can be scattered, more wires are easy to wind and damage, and the wire conveying detection is inconvenient, so in the embodiment, the wire winding wheel 24 is driven to move by the first driving piece 25, and due to the limitation of the first wire guiding wheel 11 and the limiting piece 20, the wire conveyed by the wire producing mechanism is straightened by the wire winding wheel 24 in one direction, wherein the first driving piece 25 can be a plurality of linear motion mechanisms capable of driving the wire winding wheel 24 in one direction (preferably perpendicular to the wire conveying direction, such as horizontal movement of the wire, and vertical movement of the wire winding wheel 24) can be moved to straighten the wire.

Preferably, a second wire guiding wheel 12 is arranged on the frame body 1, and a paying-off wheel 26 is arranged between the second wire guiding wheel 12 and the second wire winding roller 23; when the second winding roller 23 releases the wound cable from the tapering, the paying-off wheel 26 is moved by the first driving member 25 to straighten the released cable so that the cable can be wound up by the cable winding mechanism at a uniform speed.

Specifically, the paying-off wheel 26 guides the wire fed from the second wire winding roller 23 to the second wire winding wheel 12, the second wire winding wheel 12 guides the wire to the wire winding mechanism, the speed of winding the wire by the wire winding mechanism is basically uniform, because the compactness of the wire winding is basically consistent, therefore, when the radial dimension of the second wire winding roller 23 is shortened, a part of the wound wire is increased, if the part is not straightened, the wire between the second wire winding wheel 12 and the wire winding mechanism becomes loose, the compactness of the wire winding is ensured to be consistent, in this embodiment, the paying-off wheel 26 is driven by the first driving member 25 to move in one direction (preferably perpendicular to the wire feeding direction, such as the wire horizontal movement, the wire winding wheel 24 is moved vertically), and by the combined action of the second wire winding roller 23 and the second wire winding wheel 12, the wire which is increased when the radial dimension of the second wire winding roller 23 is shortened can be straightened.

The frame 1 is provided with a third wire guiding wheel 13 and a fourth wire guiding wheel 14, the third wire guiding wheel 13 guides the cable on the wire pulling wheel 21 to the fourth wire guiding wheel 14, and the fourth wire guiding wheel 14 guides the cable guided by the third wire guiding wheel 13 to the spark tester 10.

A fifth wire guide wheel 15 is arranged on the frame body 1, and the fifth wire guide wheel 15 guides the wire coming out of the spark tester 10 to the first wire winding roller 22.

The frame 1 is provided with a sixth wire guiding wheel 16, and the sixth wire guiding wheel 16 guides the wire coming out from the second wire winding roller 23 to the paying-off wheel 26.

Preferably, the first driving member 25 includes three tubes 250 vertically disposed on the frame 1, a floating body 251 is slidably disposed in each tube 250, a first slider 252 is slidably disposed outside the tube 250, power is transmitted between the floating body 251 and the first slider 252 through magnetic force, that is, a permanent magnetic attraction structure is disposed on each of the floating body 251 and the first slider 252, the wire drawing wheel 21, the wire winding wheel 24 and the wire releasing wheel 26 are respectively connected with the first slider 252, the liquid 253 is contained in the tube 250, and the floating body 251 is completely immersed in the liquid 253 and floats.

Specifically, when the limiting member 20 limits the cable to enter the spark testing machine 10, the cable conveyed by the cable production mechanism is gradually increased, the pressure of the cable on the take-up pulley 24 is reduced, the pressure borne by the first sliding block 252 and the corresponding floating body 251 is reduced, the whole floating body 251 is immersed in the liquid 253, the buoyancy of the floating body is basically unchanged, when the pressure given by the outside is reduced, under the action of the buoyancy, the floating body 251 drives the first sliding block 252 corresponding to the floating body to move upwards, so that the take-up pulley 24 can be driven to move upwards, the cable conveyed by the cable production mechanism is straightened by the take-up pulley 24, after the radial size of the first winding roller 22 is reduced, the produced redundant cable is straightened by the cable pulling pulley 21, also because the pressure borne by the first sliding blocks 252 and 251 corresponding to the floating body is reduced, the floating body 251 is moved upwards under the action of the floating body buoyancy, so that the cable 21 generates a pulling force on the cable, the cable can be detected again by the spark testing machine 10, the second winding roller 23 can drive the corresponding to the cable 26 to be wound up by the cable 26, and the degree of the cable is basically reduced, and the degree of the cable is kept by the fact that the cable is wound by the cable 26 is reduced.

When the cable has no defect, the limiting piece 20 removes the limitation of the cable, the radial dimension of the first winding roller 22 and the second winding roller 23 becomes larger and returns to the initial state, so that the first winding roller 22 can pull back a part of the cable pulled back by the wire pulling wheel 21, and the second winding roller 23 can pull back a part of the cable pulled by the wire releasing wheel 26, and the other part is wound by the cable winding mechanism, so that if the second winding roller 23 wants to return to the cable with the length wound in the initial state, a part of the cable needs to be wound from the first winding roller 22, and the speed of the cable produced by the cable production mechanism is basically unchanged, so that the first winding roller 22 winds a part of the cable pulled from the wire pulling wheel 24, and the wire pulling wheel 24, the wire pulling wheel 21 and the wire releasing wheel 26 return to the initial position (the initial position is the normal conveying state of the cable when the cable is not detected by the spark test press).

Since the floating body 251 is completely immersed in the liquid 253, the magnitude of the buoyancy thereof is not substantially changed, and thus the floating body 251 is moved upward by the buoyancy when the cable is normally transported, the force applied to the cable is not substantially changed, the movement of the cable is not affected, if the recoil force of the spring is used when the cable is straightened by the take-up pulley 24, the wire pulley 21 and the pay-off pulley 26, the larger the compression or stretching dimension of the elastic force of the spring is, the larger the elastic force change is, and the substantially unchanged force cannot be always given to the cable, and if the cable is pulled by the take-up pulley 24, the wire pulley 21 and the pay-off pulley 26 by using a driving mechanism alone, the structure is increased, and the cost is increased, compared with the structure used in the present embodiment, the production cost of the cable is not favorable. Moreover, the size and material selection of the floating body 251 can be adjusted based on the required force, so that the buoyancy can be controlled relatively precisely.

Specifically, when the spark tester 10 generates an alarm signal, the second driving member 205 drives the third slider 204 to move up and down in the longitudinal direction of the cross slide 202 based on the signal, the third slider 204 drives the wire pushing wheel 208 to push the cables between the two clamping wheels 207 to move down, the third slider 204 drives the two second sliders 203 positioned in the transverse direction of the cross slide 202 to approach each other through the connecting member 206, the cables between the two clamping wheels 207 become bifilar, when the two clamping wheels 207 are fully attached, the two cables are mutually extruded and limited, so that the cables cannot move in any direction at the position, wherein the connecting member 206 is in a first rod-shaped structure, one end is rotationally connected with the third slider 204, the other end is rotationally connected with the second slider 203, and also can slide (namely, one end connected with the connecting member 206 is provided with the second slider 203, a sliding groove is arranged in the sliding groove, the sliding groove can rotate in the sliding groove and also can slide, the second slider 203 is fixedly connected with the sliding shaft, when the third slider 204 is positioned at the same horizontal position between the two second sliders 203, the sliding groove 204 is positioned at the sliding groove, when the sliding groove 204 is positioned at the same horizontal position, the sliding groove 204 is close to the sliding groove 204, the sliding between the second slider 204 and the second slider 204 can move along the sliding groove 204, namely, the sliding between the two sliding wheels can be prevented from contacting the sliding along the sliding groove and the first end at the sliding groove, namely, and the sliding between the two end and the sliding wheels can move along the sliding groove can be prevented from moving relatively, and sliding along the sliding groove, and can move between the sliding groove, and can be prevented from sliding along the sliding position, and the sliding between the sliding groove and the sliding groove when the sliding groove is can and the sliding along the sliding groove and the sliding groove can and the first end can and the sliding side, the process of sliding the connecting piece 206 and the second sliding block 203 while rotating is performed, and the third sliding block 204 passes through the space between the two second sliding blocks until the connecting pieces 206 can not slide (i.e. the rotating shaft contacts with one end of the sliding groove far away from the third sliding block 204), and the two second sliding blocks 203 are driven to approach each other by the two connecting pieces 206 when the third sliding block 204 moves down.

The push wire wheel 208 can not rotate, and can give the cable friction resistance after the cable is contacted, so that the movement of the cable can be limited from the beginning, the cable is prevented from being far away from the spark testing machine 10, the retreating distance can be lengthened, the production efficiency of the cable is not improved, and the cable is limited in a rapid process, so that the cable is rapidly detected again, and the influence of the production efficiency of the cable is reduced.

Further, the first winding roller 22 and the second winding roller 23 change radial dimensions based on power when the two second sliders 203 on the second support 201 move.

Specifically, the first winding roller 22 and the second winding roller 23 have the same structure and the same radial dimension change principle, that is, the first winding roller 22 includes a roller body 220, a piston member 225 (such as a syringe structure) is disposed in the roller body 220, an air bag 226 is sleeved outside the roller body 220, two circular plates 227 are disposed at two ends of the roller body 220, when the piston member 225 is compressed, the air bag 226 can be inflated, so that the air bag 226 is limited by the two circular plates 227 to form a column shape on the roller body 220, a piston rod of the piston member 225 is a screw rod 221, one end of the screw rod is screwed with a gear 228, the gear 228 is limited by a stop lever and can only rotate on the frame body 1, each second slider 203 on the second support 201 is fixedly connected with a rack 229, the rack 229 is slidably disposed along the moving direction of the cable on the stop lever, the rack 229 is meshed with the gear 228, the air bag 226 can rotate on the roller body 220, and the roller body 220 and the frame body 1 is fixedly connected with the cable, that is capable of driving the air bag 226 to rotate on the roller body 220 when moving, but not driving the roller body 220 to rotate, so that the screw rod 228 can be driven to move linearly.

When the second slider 203 is driven to move by the third slider 204 through the connecting piece 206, the second slider 203 can drive the gear 228 to rotate through the rack 229, and the rotation of the gear 228 drives the screw rod 221 to linearly move on the roller body 220 through the threads, so as to realize the inflation and deflation process of the air bag 226, so that the limiting piece 20 can simultaneously limit the movement of the cable and the radial dimension change of the first winding roller 22 and the second winding roller 23, and the second driving piece 205 drives the third slider 204 to move in the cross sliding longitudinal direction, which can be an air cylinder or an electric push rod.

The radial dimension change of the first wire winding roller 22 and the second wire winding roller 23 needs to be realized quickly, namely the radial dimension is reduced quickly, so that the wound wire can be released to have excessive length for the wire drawing wheel to pull back, the wire releasing wheel is straightened for the wire winding mechanism to wind, if the release speed is low, the wire can not move upwards under the action of the buoyancy of the floating body 251 due to the acting force of the wire drawing wheel, the wire thus released can be wound by the wire winding mechanism, and the wire with bad points can not be retracted and detected again by the spark tester; the radial dimension becomes big fast, then the cable needs to compensate the cable length that first reel and second reel were convoluteed, and the effort of cable to take-up pulley, wire drawing wheel and unwrapping wire wheel so becomes big for take-up pulley, wire drawing wheel and unwrapping wire wheel overcome the buoyancy of corresponding body and get back to initial position.

The second driving member 205 drives the third slider 204 to move at a fast speed, so that the radial dimension of the first winding roller and the second winding roller can be changed rapidly, and the clamping wheel can be used for limiting the movement of the cable rapidly, the radial dimension of the first winding roller and the second winding roller needs to be matched completely in the process of moving the clamping wheel to clamp the cable, namely, the movement of the second slider drives the rack 229 connected with the second winding roller to move, the rack 229 moves to drive the gear 228 to rotate, the distance of the movement of the lead screw 221 can be just enough to enable the first winding roller or the second winding roller to be reduced by the thickness, the foremost is that the cable length of the first winding roller released by the thickness can be just enough to be pulled back by the spark tester again, the time of the cable length of the second winding roller released by the thickness after being straightened by the paying-off wheel is matched with the time of the cable pulled back by the cable to be detected by the spark tester, and the situation that the corresponding winding roller can be increased when the first winding roller and the second winding roller are in a short moving path, and the corresponding winding roller can be opened when the first winding roller and the second winding roller can be opened by the corresponding winding roller in a short path.

Still further, an extrusion member is disposed on the second support 201, and when the third slider 204 on the second support 201 moves downward, the extrusion member applies an extrusion force to the rotating shaft of the clamping wheel 207, so that the clamping wheel 207 stops rotating.

Specifically, in the foregoing, the position of the third slider 204 is above the position of the second slider 203, when the third slider 204 moves up and down longitudinally, the connecting piece 206 and the second slider 203 slide while rotating, when the third slider 204 moves below the position of the second slider 203, and when the connecting piece 206 and the second slider 203 can no longer slide, the third slider 204 continues to move down, the two second sliders 203 can be pulled by the two connecting pieces 206 to close to each other to clamp the cable, and in this process, the two second sliders 203 are not close to each other, the gear 228 cannot be driven to rotate by the rack 229, the radial dimensions of the first winding roller 22 and the second winding roller 23 cannot be reduced simultaneously, and when the two clamping wheels 207 are close to each other, a part of the cable is pulled from the first winding roller 22 and the second winding roller 23, so that a bad cable position on the cable is possibly caused, or when the cable is not clamped back, the cable is too close to each other, the cable is not detected.

Therefore, in this embodiment, when the third slider 204 on the second support plate 201 is driven to move down by the second driving member 205, the extrusion can timely apply extrusion force to the rotation of the clamping wheel 207, so that the clamping wheel 207 can rotate without being moved by the cable, then the push wire wheel 208 and the clamping wheel 207 simultaneously perform preliminary limitation on the movement of the cable, and after the clamping wheel 207 does not rotate, the two clamping wheels 207 can be pulled to approach each other by the cable between the two clamping wheels 207 when the push wire wheel 208 moves down, only when the two clamping wheels 207 approach each other, a part of cable can be pulled from the first winding roller 22 and the second winding roller 23, the bad point on the cable is reduced to too close to the clamping position as much as possible, and the two second sliders 203 also approach each other as early as possible, so as to drive the rack 229 to move, and the rack 229 drives the gear 228 to rotate, so that the radial dimension of the first winding roller 22 and the second winding roller 23 becomes smaller simultaneously.

The air bag 226 has a certain elasticity compared with the plate 223, and the surface of the air bag 226 can be completely contacted when the cable is wound on the surface of the air bag 226, and after the plate 223 is far away from the center line of the roller 220, a gap is formed between the adjacent plate 223, so that the cable is not completely supported by the plate 223 after being wound, the cable can be bent at a certain angle at the position contacted with the edge of the plate 223, after the radial sizes of the first winding roller 22 and the second winding roller 23 are reduced, the bent position is contacted with the plate 223, and the interaction force between the two is increased, so that the movement of the cable is not facilitated.

The extrusion piece comprises a friction block 230 which is arranged on the second sliding block 203 in a sliding manner, an elastic piece is connected between the friction block 230 and the second sliding block 203 in the sliding direction, a gravity extrusion block 231 is arranged on the second supporting plate 201 in a sliding manner, the gravity extrusion block 231 is driven to extrude the friction block 230 to be in contact with a rotating shaft of the clamping wheel 207 when the third sliding block 204 moves downwards so as to limit the rotation of the clamping wheel 207, the third sliding block 204 can move downwards continuously, the gravity extrusion block 231 can be driven to move upwards after the third sliding block 204 moves upwards so as to separate from the extrusion of the friction block 230, the friction block 230 is separated from the extrusion of the rotating shaft of the clamping wheel 207 under the action of resilience force of the elastic piece, and thus the rotation limit of the clamping wheel 207 disappears.

The third slider 204 moves down to enable the gravity extrusion block 231 to move down to extrude the friction block 230, when the third slider 204 moves up, the gravity extrusion block 231 can be driven to move up to extrude the friction block 230, the gravity extrusion block 231 cannot move down further after extruding the friction block 230, the third slider 204 can not move down further, so that a first abutting surface can be arranged on the third slider 204, a second abutting surface is arranged on the gravity extrusion block 231, the first abutting surface faces up, the second abutting surface faces down, when the third slider 204 moves down, the first abutting surface supports the second abutting surface, the gravity extrusion block 231 moves down under the action of gravity to extrude the friction block 230, when the gravity extrusion block 231 extrudes the friction block 230, the gravity extrusion block 230 can be limited by the friction block 230 to move down again, and the third slider 204 can move down further, so that the first abutting surface is separated from the second abutting surface, when the third slider 204 moves up, the first abutting surface is in contact with the second abutting surface, and the gravity extrusion block 231 is pushed down again, so that the gravity extrusion block 231 is separated from the first abutting surface, and the gravity extrusion block 231 is extruded up.
