Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of cable straightening, in particular to an automatic multi-stage cable straightening device. BACKGROUND

[0002] The cable straightening device is a mechanical equipment or tool for correcting the deformation of cables (such as wires, cables, optical fibers, and metal wires) caused during production, transportation, or use, such as bending, twisting, and curling, so as to restore them to a straight state.

[0003] The patent with the announcement number CN212733928U discloses a high-efficiency cable straightening device, which comprises a base, two straightening units are installed on the base, the two straightening units are vertically and horizontally arranged and close to each other, the straightening unit comprises mounting plates one and two which are stacked and fixed to each other, a plurality of notches are rotationally arranged on the mounting plate one, a push plate is slidingly arranged in the notch, a driving roller is rotationally arranged on the side wall close to the fixed roller one end of the push plate, a pulley is rotationally arranged on the end of the push plate away from the driving roller, a rack is slidingly arranged on the mounting plate two, a plurality of triangular plates are fixedly arranged on the side wall away from the tooth surface of the rack, a gear one is engaged on the tooth surface of the rack, and the gear one is rotationally connected with the mounting plate two; the mounting plate two is provided with a locking mechanism for locking or releasing the gear one. The device can adapt to cables of different diameters to improve the working efficiency.

[0004] However, the above-mentioned straightening device still has the following problems in actual use: When the cable passes through the straightening machine for straightening, it is usually composed of multiple layers of different materials (such as copper conductor, PVC insulation layer, and nylon sheath), and has a complex structure and anisotropic mechanical properties. The current mainstream straightening equipment mainly adopts a single-stage straightening method, that is, a plurality of V-shaped rollers on the upper part are driven by a hydraulic device to press downward, and a V-shaped supporting roller at the bottom is fixed to apply pressure to the cable to achieve straightening.

[0005] However, the bending mode of the cable is not limited to the "wavy bending" in the plane, but also often exists in the form of "spiral bending" or three-dimensional twisting. The single-stage straightening structure has obvious "unidirectional" characteristics, and can only effectively correct the deformation in one direction, and it is difficult to eliminate the bending stress in the vertical direction or other spatial dimensions.

[0006] This leads to the fact that the overall straightness of the straightened cable is still not ideal, which may need to be straightened repeatedly, increasing the processing cost, and even may damage the internal structure or outer sheath of the cable due to excessive extrusion, affecting its electrical performance and service life.

[0023] It needs to be particularly pointed out here that: see Figures 1-4 The structures of the two straightening modules are the same, only the directions are different, and the number of the straightening modules is not limited to two, but can be more. The present application only shows two for the convenience of text description and figure display, and the specific number is not limited. In addition, this and the following are described from the perspective of Figure 1 The right straightening module refers to Figure 1 the horizontal part in the right side of the bottom plate 1 in the figure, Figure 1 and the vertical part of the straightening module in the middle of the bottom plate 1 in the figure.

[0024] As a preferred scheme of the present application, the transmission assembly includes a conveying motor 10, a first rod 13, a synchronization assembly and a plurality of second rods 14, the conveying motor 10 is fixedly connected with the L-shaped plate 4 through a base, the output shaft of the conveying motor 10 is fixedly connected with one end of the first rod 13, the first rod 13 and the plurality of second rods 14 are all parallel, and the ends of the first rod 13 and the plurality of second rods 14 away from the conveying motor 10 are respectively fixedly connected with the plurality of directional wheels 2, and the two ends of the synchronization assembly are respectively connected with the first rod 13 and the second rod 14.

[0025] More specifically, by setting two transmission assemblies, power can be provided to the directional wheels 2 in the two straightening modules, and then the cable to be straightened (hereinafter referred to as the bent cable) can be clamped and fed into the straightening module in the middle of the base plate 1 under the action of the hydraulic rod 5, so that the bent cable can be straightened from multiple directions.

[0026] As a preferred embodiment of the present application, the synchronous assembly comprises a synchronous belt 31 and two synchronous wheels 30, which are sleeved and fixedly connected to the outer walls of the first rod 13 and the second rod 14 respectively, and the synchronous belt 31 is sleeved outside the two synchronous wheels 30.

[0027] More specifically, by setting the synchronous assembly, power can be provided to the directional wheels 2 in one straightening module at the same time through one conveying motor 10, thereby reducing the probability of slipping. It should be particularly noted that in actual application, the synchronous assembly can be multiple, and the specific number is not limited.

[0028] As shown in the above description, Figures 1 to 10 In use, the automatic multi-stage cable straightening device in the present application only needs to be stably placed (or directly fixed) on the table top, and then the cable to be straightened (hereinafter referred to as the bent cable) is passed between the directional wheels 2 and the adjusting wheels 3 of the straightening module on the right side of the base plate 1, and then the hydraulic rod 5 on the right side of the straightening module is turned on. After the hydraulic rod 5 is started, the output end of the hydraulic rod 5 pushes the U-shaped frame 12 to move inside the L-shaped plate 4 through the guide rods 6, so that the adjusting wheels 3 connected to the inside of the U-shaped frame 12 are pushed towards the directional wheels 2, thereby limiting the bent cable from one angle together with the directional wheels 2, so that the bent cable cannot fall out of the straightening module. Then the conveying motor 10 on the left side of the straightening module is turned on, and after the conveying motor 10 is started, the output shaft rotates with the first rod 13, and the first rod 13 rotates with the synchronous wheel 30 on the surface, and then the synchronous wheel 30 rotates with the other synchronous wheel 30 connected to the second rod 14 through the synchronous belt 31, at the same time, the first rod 13 and the second rod 14 rotate with the directional wheels 2, thereby conveying the cable between the directional wheels 2 and the adjusting wheels 3 to the straightening module in the base plate 1. When the bent cable enters between the directional wheels 2 and the adjusting wheels 3 of the second straightening module, the hydraulic rod 5 of the middle straightening module is started, and then the bent cable is straightened from another angle according to the above method, thereby straightening the bent cable from multiple angles, so that the bent cable can be straightened at one time, which is convenient, fast and easy to operate (if there are multiple straightening modules, the effect can be achieved after the bent cable passes through all the straightening modules).

[0029] As a preferred scheme of the present application, one end of the bottom plate 1 is connected with two limiting blocks 8, the two limiting blocks 8 are fixedly connected with a slip ring stator 7, the inner wall of the slip ring stator 7 is rotatably connected with a slip ring rotor 16, the inner wall of the slip ring rotor 16 is fixedly connected with a visual camera 36 and two clamping mechanisms, the two clamping mechanisms are symmetrical, the two clamping mechanisms are located on the side of the slip ring rotor 16 away from the bottom plate 1, the visual camera 36 is located on the side of the slip ring rotor 16 close to the bottom plate 1, and the slip ring stator 7, the slip ring rotor 16, the visual camera 36 and the two clamping mechanisms are located on the side of the first straightening module away from the second straightening module.

[0030] The clamping mechanism comprises an electric push rod 17 and an arc-shaped plate 18, the outer wall of the electric push rod 17 is fixedly connected with the inner wall of the slip ring rotor 16, the output end of the electric push rod 17 is fixedly connected with the outer side wall of the arc-shaped plate 18, and the inner side wall of the arc-shaped plate 18 faces the center of the slip ring rotor 16.

[0031] One of the arc-shaped plates 18 is internally provided with a liquid storage cavity 39, an observation port 37 is penetratingly formed on the side of the liquid storage cavity 39 close to the bottom plate 1, the inner wall of the observation port 37 is fixedly connected with a transparent glass, a liquid supplement pipe 38 is fixedly connected on the side of the liquid storage cavity 39 close to the bottom plate 1, the inner wall of the liquid supplement pipe 38 is threadedly connected with a sealing plug, and a marker cotton 25 is fixedly connected on the side of the liquid storage cavity 39 close to the center of the slip ring rotor 16.

[0032] More specifically, after the curved cable passes through all the straightening modules, the curved cable may have cracks on the surface due to the multiple straightening steps, and in order to avoid the influence of these cracks on the subsequent use, two limiting blocks 8 are arranged on the leftmost side of the bottom plate 1, and a slip ring stator 7 and a slip ring rotor 16 are arranged between the two limiting blocks 8. When the straightened curved cable (hereinafter referred to as a straight cable) passes through the last straightening module, the end of the straight cable will be inserted into the slip ring stator 7 and the slip ring rotor 16, and at this time the visual camera 36 located on the side of the slip ring rotor 16 close to the bottom plate 1 will detect the slip ring rotor 16 passing through first. During the process that the slip ring rotor 16 passes through the visual camera 36, the visual camera 36 detects the surface of the straight cable in real time, and if cracks are detected, the visual camera 36 can transmit an electrical signal to an external processor, and then two electric push rods 17 are immediately turned on at the same time through an external controller (such as a PLC controller). When the electric push rod 17 is started, the output end thereof extends outward and pushes the arc-shaped plates 18 to move, and because the inner part of one of the arc-shaped plates 18 is provided with a liquid storage cavity 39 and the liquid storage cavity 39 is provided with a marking cotton 25 on the side close to the linear cable, as the two arc-shaped plates 18 move close to the linear cable, the two arc-shaped plates 18 can simultaneously abut against the surface of the linear cable from both sides of the linear cable, so that the marking cotton 25 can mark on the contact position with the linear cable; At this time and later, the staff finds the mark, and can manually (or more accurately, mechanically) re-inspect this part of the linear cable, and after re-inspection, cut, repair, discard, rework, etc. It should be particularly pointed out here that: when the visual camera 36 transmits the crack signal, the electric push rod 17 is started at the same time, and an audible and visual alarm is triggered by an external controller to timely remind, which is not limited in detail; In addition, two electric push rods 17 and arc-shaped plates 18 are arranged to avoid the straightened linear cable being bent again due to extrusion when only one arc-shaped plate 18 abuts against the surface of the linear cable.

[0033] As a preferred scheme of the present application, the outer wall of the slip ring stator 7 is connected with a rotating mechanism, and the output end of the rotating mechanism is connected with the slip ring rotor 16.

[0034] The rotating mechanism comprises a rotating motor 26, a worm gear 29, a fourth rod 32, a worm 33 and two supporting blocks 28, one end of each of the two supporting blocks 28 is fixedly connected with the outer wall of the slip ring stator 7, the outer wall of the rotating motor 26 is fixedly connected with the side wall of one of the two supporting blocks 28, the output shaft of the rotating motor 26 is fixedly connected with one end of the fourth rod 32, the other end of the fourth rod 32 penetrates through the two supporting blocks 28 and is rotationally connected with the two supporting blocks 28, the worm 33 is sleeved and fixedly connected on the outer wall of the fourth rod 32, one side of the worm gear 29 is fixedly connected with the side of the slip ring rotor 16 close to the bottom plate 1, and the worm gear 29 is engaged with the worm 33.

[0035] More specifically, because the cross section of the linear cable is cylindrical, the detection line of the visual camera 36 may be blocked, in order to improve the detection accuracy, a rotating mechanism is arranged between the second rod 14 and the slip ring rotor 16, which can rotate the slip ring rotor 16 at the same time when the linear cable is conveyed by the directional wheel 2, so that the visual camera 36 in the rotating process can realize more accurate detection; The specific steps are: when the conveying motor 10 starts, the second rod 14 rotates due to the synchronous belt 31 and the synchronous wheel 30, and the plurality of directional wheels 2 rotate at the same time, and at the same time when the conveying motor 10 starts, the rotating motor 26 starts, and then the output shaft of the rotating motor 26 drives the fourth rod 32 to rotate inside the two supporting blocks 28, so as to drive the worm 33 on the surface of the fourth rod 32 to rotate, and when the worm 33 rotates, the worm wheel 29 connected with the slip ring rotor 16 rotates, so that the visual camera 36 and the two electric push rods 17 inside the slip ring rotor 16 rotate (because the two electric push rods 17 are symmetrical, even if the electric push rod 17 rotates with the visual camera 36, the relative position is constant, so it will not affect the clamping and marking effect).

[0036] As a preferred scheme of the present application, the first U-shaped frame 12 is fixedly connected with a connecting plate 23 at both ends, the other end of the connecting plate 23 is fixedly connected with a first rack plate 19, the upper surface of the bottom plate 1 is fixedly connected with two guide plates 24, the inner wall of the upper end of the guide plate 24 is fixedly connected with two fifth rods 34, the other end of the two fifth rods 34 is rotatably connected with a pinion 20 and a gear 21 respectively, the side of the guide plate 24 close to the pinion 20 is slidably connected with a second rack plate 22, the side wall of the second rack plate 22 is fixedly connected with one of the limiting blocks 8, the first rack plate 19 is engaged with the pinion 20, the pinion 20 is also engaged with the gear 21, and the gear 21 is engaged with the second rack plate 22.

[0037] More specifically, because the cable to be straightened is different in thickness, the pushing distance of the hydraulic rod 5 is set according to the thickness during straightening, so as to ensure that the distance between the adjusting wheel 3 and the directional wheel 2 is always in a state capable of straightening the bent cable, but as the distance between the adjusting wheel 3 and the directional wheel 2 changes, the straight cable and the slip ring rotor 16 will not be in a "concentric circle" state, which may cause the distance between the two arc-shaped plates 18 and the straight cable to change, thereby causing the straight cable to be bent; At this time, the connecting plate 23, the first rack plate 19 and the second rack plate 22 are arranged between the U-shaped frame 12 at the middle position and the slip ring stator 7, and the guide plate 24 is arranged on the bottom plate 1, the support pinion 20 and the gear 21 are rotated through the guide plate 24, when the U-shaped frame 12 at the middle position rises, the U-shaped frame 12 rises with the connecting plate 23, the connecting plate 23 rises with the first rack plate 19, then the first rack plate 19 rotates the pinion 20 counterclockwise, the pinion 20 rotates the gear 21 clockwise, then the gear 21 rises with the second rack plate 22, because the number of teeth of the pinion 20 is half of the number of teeth of the gear 21, if the U-shaped frame 12 rises 4 cm, the slip ring stator 7 only rises 2 cm, because the height of the directional wheel 2 is unchanged, it can be ensured that the slip ring stator 7 and the straight cable between the directional wheel 2 and the adjusting wheel 3 are still in the “same center” state. In addition, because the U-shaped frame 12 at the middle position is also connected with the L-shaped plate 4 of the right position straightening module through another connecting plate 23, the first rack plate 19 and the second rack plate 22 and the like, when the U-shaped frame 12 at the middle position rises 4 cm, the total height of the right straightening module also rises 2 cm (if there are other straightening modules, they can be connected with the U-shaped frame 12 at the middle position through the connecting plate 23, the first rack plate 19 and the second rack plate 22 and the like, so as to ensure synchronous lifting, and the lifting height is only half of the U-shaped frame 12 at the middle position); It should be particularly noted that: the curved cable can be understood as rough straightening when passing through the right straightening module, the curved cable at this time has a large bending (for example, spiral), after the curved cable passes through the right straightening module, it is straightened into a small amplitude bending, when the small amplitude bending cable passes through the middle straightening module, it is completely straightened into a straight line (in actual application process, because the total number of straightening modules is not limited, but the final purpose is to straighten into a straight line), therefore, the right straightening module does not necessarily and cannot be concentric with the slip ring stator 7, the right straightening module is connected with the middle straightening module through another gear and rack group (the first rack plate 19 and the second rack plate 22, the pinion 20 and the gear 21), the purpose is to ensure that the heights of the two straightening modules are the same as far as possible, so that when the curved cable enters the middle straightening module, there is no bending in two directions, therefore, the right straightening can only ensure the same height as the center of the slip ring stator 7, but the curved cable inside the right straightening module is not concentric with the slip ring stator 7, only the straight cable inside the straightening module closest to the slip ring stator 7 always keeps concentric with the slip ring stator 7.

[0038] As a preferred scheme of the present application, the upper surface of the bottom plate 1 is fixedly connected with an auxiliary rod 27, the auxiliary rod 27 and one side of the two connecting plates 23 are both provided with T-shaped grooves 40, the limiting block 8 away from the first rack plate 19 is fixedly connected with a lifting rod 9, the lifting rod 9, the first rack plate 19 and one side of the lower end of the second rack plate 22 are all fixedly connected with T-shaped blocks 35, and the three T-shaped blocks 35 are respectively in sliding connection with the three T-shaped grooves 40. More specifically, by arranging the auxiliary rod 27 and the lifting rod 9, and by arranging the T-shaped grooves 40 and the matched T-shaped blocks 35, not only can an end of the slip ring stator 7 away from the second rack plate 22 be supported when the slip ring stator 7 is lifted, but also a lifting moving track can be provided for the first rack plate 19 and the second rack plate 22, so as to reduce the probability of deformation of the first rack plate 19 and the second rack plate 22. It should be particularly noted that the connecting plates 23, the first rack plate 19, the second rack plate 22, the auxiliary rod 27 and the lifting rod 9 are all made of steel, so as to ensure the supporting effect and the hardness.
