Description

Cable shielding net cutting device and method Technical Field

[0001] The present invention relates to the technical field of cable processing, and in particular to a cable shielding net cutting device and method. Background Art

[0002] Shielding mesh refers to a metal mesh braided layer wrapped around the transmission line. Its main function is to reduce the impact of external electromagnetic fields on the power supply or communication lines. At the same time, the shielding mesh also has the function of preventing the line from radiating electromagnetic energy outward. In conventional wire harnesses with shielding mesh, a layer of metal foil is often wrapped inside the shielding mesh. When processing the cable, such as cutting the shielding wire, it is easy to cause a certain impact on the inner metal foil.

[0003] In the related art, in order to avoid the impact of the cutting of the shielding mesh on the inner metal foil, the method of turning over and cutting is often adopted, that is, the shielding mesh is turned outward first, and then a part of the shielding mesh is cut on the outer cover. After the cutting is completed, the remaining shielding mesh is folded inward and the subsequent operation is continued;

[0004] However, the inventors found that the above-mentioned method of turning the shielding wire inside out after cutting the shielding wire outside out can easily cause certain damage to the outer insulation layer. On the other hand, the shielding wires after turning inside out are more messy, which can easily affect subsequent operations. Summary of the Invention

[0005] In view of at least one of the above technical problems, the present invention provides a cable shielding mesh cutting device and method, which adopts a change in the cutting method to avoid damage to the outer insulation and improve the smoothness of the shielding wire.

[0009] The cutting mechanism is used to synchronously cut the folded shielding wire and the outer sheath under the shielding wire;

[0010] The semi-stripping copper ring mechanism is used to pull the outer jacket under the shielding wire out a set distance so that the shielding wire turned outward is pressed inside the outer jacket, and the copper ring is crimped onto the outer insulation layer and the shielding wire, and the outer jacket is stripped;

[0011] The second wire turning and sorting mechanism is used to turn the shielding wire 180 degrees and cover it on the copper ring.

[0012] In some embodiments of the present invention, the peeling mechanism includes a coaxial peeling tool, a first drive assembly for driving the coaxial peeling tool to rotate and move closer to or away from each other, and a second drive assembly for driving the coaxial peeling tool to move axially.

[0014] In some embodiments of the present invention, the cutting mechanism includes a cutting knife and an auxiliary clamp arranged on a side away from the cutting knife, and the auxiliary clamp is used to clamp the outer insulation layer and the folded shielding wire at the same time.

[0015] In some embodiments of the present invention, the auxiliary clamp includes a first clamping portion, a second clamping portion, and a hollow portion arranged between the first clamping portion and the second clamping portion, the first clamping portion is used to clamp the cut rear section of the shielding wire after folding, the second clamping portion is used to clamp the cable, and the hollow portion is used to accommodate the free end of the shielding wire.

[0016] In some embodiments of the present invention, the cutting mechanism further has an auxiliary clamp opening component that moves toward or away from the middle of the auxiliary clamp, and the auxiliary clamp opening component includes a cone head that moves toward or away from the middle of the auxiliary clamp to assist in opening the auxiliary clamp.

[0017] In some embodiments of the present invention, the semi-stripping copper ring mechanism includes a crimping seat, a crimping head arranged opposite to the crimping seat, and a feeding assembly for conveying the copper ring row.

[0018] In some embodiments of the present invention, the semi-stripping copper ring mechanism also includes a stripping mechanism, which includes a stripping knife arranged in the axial direction of the crimping seat and a stripping drive that drives the stripping knife axially close to or away from the crimping seat. The stripping knife is configured to move in a direction away from the crimping seat after extending into the cutting seam between the shielding wire and the outer insulation skin for a second movement. The secondary movement includes a first movement of pulling the outer insulation skin to a distance required for copper ring crimping, and also includes a second stripping movement after the copper ring crimping is completed.

[0019] In some embodiments of the present invention, a cleaning mechanism is further provided between the cutting mechanism and the semi-peeling copper ring mechanism, and the cleaning mechanism comprises two oppositely arranged bellows, one of the two bellows having an air blowing port and the other having an air exhaust port.

[0020] According to a second aspect of the present invention, a cable shielding mesh cutting method is provided, using the cable shielding mesh cutting device described in any one of the first aspects, comprising the following steps:

[0026] Fold the shielding net back and continue to fold the shielding wire 180 degrees toward the crimped copper ring so that the shielding wire covers the copper ring.

[0027] The beneficial effects of the present invention are as follows: the present invention first turns the shielding wire onto the insulation skin, then cuts the shielding wire and the insulation skin synchronously, and then flattens the shielding wire by pulling back the cut insulation skin under the shielding wire, and then crimps the copper ring on the flattened shielding wire part. Compared with the prior art, this type of equipment setting not only ensures the smoothness of the crimping after the shielding wire is cut, but also prevents the insulation skin from falling off after cutting, thereby avoiding the influence of the cutting of the shielding wire on the insulation skin.

[0039] The technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0040] It should be noted that when an element is referred to as being "fixed to" another element, it may be directly attached to the other element or there may be an intermediate element. When an element is referred to as being "connected to" another element, it may be directly connected to the other element or there may be an intermediate element. The terms "vertical," "horizontal," "left," "right," and similar expressions used herein are for illustrative purposes only and do not represent the only implementation methods.

[0041] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by those skilled in the art to which this invention pertains. The terms used in this specification are for the purpose of describing specific embodiments only and are not intended to limit the invention. The term "and / or" as used herein includes any and all combinations of one or more of the associated listed items.

[0042] The cable shielding net cutting device shown in Figures 1 to 6 includes a skinning mechanism 1, a first wire turning and sorting mechanism 2, a cutting mechanism 3, a semi-stripping and pressing copper ring mechanism 4, and a second wire turning and sorting mechanism 5. It should be noted that the switching of cables between the various mechanisms in the embodiment of the present invention can be achieved manually or by adopting an existing clamping loop line structure. The specific structural form will not be described in detail here.

[0043] 1 and 2 , the actions and functions implemented by each device in the embodiment of the present invention are described in detail. The skinning mechanism 1 is used to cut and strip the insulation skin on the outside of the shielding net; as shown in the structural diagram of the cable on the far left in FIG2 , the skinning mechanism 1 cuts the outer insulation skin of the cable. It should be noted that the cable skin cutting mechanism 3 has various forms, such as a rotary cutting structure or a half-cutting form with a flat knife, that is, by bringing two V-shaped cutters close to each other, the outer insulation skin of the cable is partially cut, and then the outer insulation skin is removed by clamping and pulling back; it should be noted that in this embodiment of the present invention, when the skin is removed for the first time, the length of the removed skin is less than the length of the outer insulation skin set to be stripped;

[0044] 1 and 2, the first wire turning and sorting mechanism 2 is used to break up the exposed shielding wires and fold them 180 degrees onto the outer insulation skin; the wire turning and sorting mechanism is used to first straighten the braided shielding mesh so that the shielding mesh becomes strips of shielding wires, and then flip the shielding wires onto the insulation skin on the second cable as shown in FIG2, that is, the shielding wires originally facing upward in FIG2 are flipped 180 degrees downward. The wire turning and sorting mechanism also has a variety of structural forms in the prior art. For example, the rotation of a rotating wheel with bristles is used to achieve breaking up when the brush wheel rotates forward and turning the wires when the brush wheel rotates reversely. Its structural form will not be described in detail here;

[0045] The cutting mechanism 3 is used to synchronously cut the folded shielding wire and the outer sheath under the shielding wire; as shown in the third cable in Figure 2, in the embodiment of the present invention, unlike the prior art, the present application not only cuts the shielding wire that needs to be removed, but also cuts the insulation skin under the shielding wire. It should be pointed out here that in the present invention, the second cutting distance of the outer insulation skin plus the total length of the first outer insulation skin removal is the length that needs to be stripped. The insulation skin cut for the second time can not only avoid damage to the internal metal foil, but also can play the role of straightening and temporarily holding the remaining shielding wire after cutting;

[0046] The semi-stripping copper ring mechanism 4 is used to pull the outer sheath under the shielding wire out a set distance, so that the outward-turned shielding wire is pressed and held inside the outer sheath, and the copper ring is crimped onto the outer insulation layer and the shielding wire, and the outer sheath is peeled off; as shown in the structural schematic diagram of the last three wire harnesses in Figure 2, in an embodiment of the present invention, the insulation skin cut off for the second time is first pulled outward, so that the shielding wire is gathered inward until it is completely contained in the outer insulation skin. This semi-stripping method can be used to tighten the outward-turned shielding wire so that the shielding wire is attached to the metal foil of the cable, and at the same time, the shielding wire is held tightly to avoid the shielding wire from being scattered when the copper ring is crimped. When the copper ring is crimped, the outer insulation skin cut for the second time still remains on the cable. After the copper ring is crimped, the outer insulation skin cut for the second time is removed, and the shielding wire is now attached to the metal foil of the cable.

[0047] Continuing to refer to Figures 1 and 2, in an embodiment of the present invention, the second wire turning and organizing mechanism 5 is used to fold the shielding wire 180 degrees and cover it on the copper ring. The second wire turning and organizing mechanism 5 has the same structural form as the first wire turning and organizing mechanism 2. Its function is to turn the shielding wire attached to the metal foil on the cable so that the shielding wire covers the crimped copper ring. This structural form facilitates subsequent operations to avoid being affected by the shielding wire. On the other hand, the shielding wire covering the copper ring also improves the contact reliability between the shielding wire and the copper ring.

[0048] In the above embodiment, the shielding wire is first folded onto the insulation skin, and then the shielding wire and the insulation skin are cut synchronously, and then the cut insulation skin under the shielding wire is pulled back to flatten the shielding wire, and then the copper ring is crimped on the flattened shielding wire part. Compared with the existing technology, this type of equipment setting not only ensures the smoothness of the crimping after the shielding wire is cut, but also prevents the insulation skin from falling off after cutting, thereby avoiding the impact of the cutting of the shielding wire on the insulation skin.

[0049] Based on the above embodiment, the following part of the embodiment of the present invention will provide a detailed introduction to the structural form of the above mechanism. Of course, it should be pointed out here that the mechanism described below is an implementation method in the embodiment of the present invention and is not a limitation of the above scheme. As shown in Figure 3, the peeling mechanism 1 includes a coaxial peeling tool 11, a first drive assembly 12 for driving the coaxial peeling tool 11 to rotate and move closer to or away from each other, and a second drive assembly 13 for driving the coaxial peeling tool 11 to move axially. When peeling, the two opposing blades on the coaxial peeling tool 11 approach each other and rotate to cut the outer insulation, and then the blade is stuck in the cutting seam of the outer insulation by moving axially away from the cable to peel the outer insulation from the cable.

[0050] In an embodiment of the present invention, as shown in FIG4 , the first wire turning and sorting mechanism 2 and the second wire turning and sorting mechanism 5 both include a clamping mechanism 21, a wire sorting brush wheel 22 provided on the clamping mechanism 21, a rotating drive member 23 for driving the clamping mechanism 21 to rotate, and a wire turning drive member 24 for driving the clamping mechanism 21 to move axially. The clamping mechanism 21 here can adopt a structure such as a clamping claw cylinder. As shown in FIG4 , the wire sorting brush wheel 22 has bristles with a certain hardness. By rotating the wire sorting brush wheel 22, the shielding wire is straightened, and then the wire turning drive member 24 moves toward the direction of the cable, and the wire sorting brush wheel 22 flips, and at the same time, the rotating drive member 23 rotates, so as to realize the operation of flipping the shielding wire 180 degrees and fitting it on the outer insulation skin.

[0051] The specific structure of the cutting mechanism 3 is shown in Figures 5 and 6. In this embodiment of the present invention, the cutting mechanism 3 includes a cutting blade 31 and an auxiliary clamp 32 disposed on a side away from the cutting blade 31. The auxiliary clamp 32 is used to simultaneously clamp the outer insulation layer and the folded shielding wire. In this embodiment of the present invention, since the folded shielding wire is only attached to the outer insulation layer, the movement of the shielding wire during cutting will affect the cutting effect. The provision of the auxiliary clamp 32 can effectively prevent the movement of the shielding wire and improve the cutting effect.

[0052] The specific structure of the auxiliary clamp 32 is shown in Figure 6. The auxiliary clamp 32 includes a first clamping portion, a second clamping portion, and a hollow portion disposed between the first and second clamping portions. The first clamping portion is used to clamp the folded-back section of the shielding wire after cutting, the second clamping portion is used to clamp the cable, and the hollow portion is used to accommodate the free end of the shielding wire. Through this arrangement, before cutting, the first clamping portion simultaneously clamps the folded-back shielding wire and the insulation layer inside the shielding wire, and protrudes the portion to be cut from the outside of the first clamping portion. The free end of the shielding wire is then placed in the hollow portion to facilitate the free fall of the shielding wire after cutting. The clamping of the second clamping portion can ensure the straightness of the cable and prevent the cable from shaking during cutting, thereby further improving the cutting accuracy.

[0053] Continuing with reference to FIG5 , in some embodiments of the present invention, to prevent the cut shielding wire from affecting the opening and closing of the auxiliary clamp 32, the cutting mechanism 3 further includes an auxiliary clamp opening assembly 33 that moves toward or away from the center of the auxiliary clamp 32. The auxiliary clamp opening assembly 33 includes a cone head 33a that moves toward or away from the center of the auxiliary clamp 32 to assist in opening the auxiliary clamp 32. As shown in FIG5 , in some embodiments of the present invention, the cone head 33a is positioned toward the center of the two auxiliary clamps 32. The conical structure of the cone head 33a allows the two auxiliary clamps 32 to be pushed apart, thereby preventing the auxiliary clamps 32 from being unable to open. This arrangement improves the reliability of cutting and the stability of equipment operation.

[0054] As shown in Figures 7 and 8, in an embodiment of the present invention, the semi-stripped copper ring mechanism 4 includes a crimping seat 41, a crimping head 42 arranged opposite to the crimping seat 41, and a feeding assembly 43 for conveying the copper ring row. The crimping of the copper ring is a prior art. The copper ring row is sequentially conveyed to the crimping seat 41 by unwinding the feeding mechanism, and then the cable body and the exposed shielding wire portion are placed on the U-shaped copper ring. Through crimping, as shown in the penultimate cable in Figure 2, the rear half of the crimped copper ring is crimped to the cable body, and the front half is crimped to the shielding wire, thereby achieving reliable fixation of the shielding wire.

[0055] Please continue to refer to Figure 8. Unlike the conventional crimping mechanism in the prior art, in the embodiment of the present invention, the semi-stripping copper ring mechanism 4 also includes a stripping mechanism 44. The stripping mechanism 44 includes a stripping knife 44a arranged in the axial direction of the crimping seat 41 and a stripping drive 44b that drives the stripping knife 44a to move axially toward or away from the crimping seat 41. The stripping knife 44a is configured to move in a direction away from the crimping seat 41 after extending into the slit between the shielding wire and the outer insulation skin, and then perform a secondary movement. The secondary movement includes a first movement to pull the outer insulation skin to a distance sufficient for copper ring crimping, and also includes a second stripping movement after the copper ring crimping is completed. Through such a setting, the outer insulation skin that is cut for the second time is pulled by the glass mechanism before crimping, so that the outer insulation skin straightens the shielding wire while also holding the shielding wire tightly, thereby avoiding the disarray of the shielding wire and improving the reliability of the copper ring crimping.

[0056] In addition, in order to prevent the cut shielding wire from sticking to the wiring harness and affecting subsequent operations, in an embodiment of the present invention, a cleaning mechanism 6 is further provided between the cutting mechanism 3 and the semi-stripping copper ring mechanism 4. As shown in FIG9 , the cleaning mechanism 6 includes two oppositely arranged bellows 61, one of which has an air blowing port and the other has an air exhaust port 61b. After the shielding wire is cut, in an embodiment of the present invention, the two opposite bellows 61 are opened so that the cut portion of the shielding wire on the wiring harness is completely between the two bellows 61. After the two bellows 61 are relatively close to each other, air is blown into the bellows 61 through the air blowing port to remove the cut shielding wire attached to the wiring harness, and then the waste is discharged through the air exhaust port 61b. Through the above arrangement, the influence of the residual shielding wire on the wiring harness is avoided, and the reliability of the shielding wire cutting is improved.

[0057] In an embodiment of the present invention, a cable shielding mesh cutting method as shown in FIG10 is also provided. Using the above-mentioned cable shielding mesh cutting device, those skilled in the art can understand the following method based on the description of the device above, and will not be described in detail here. The method includes the following steps:

[0058] S10: Cutting the outer jacket: Cut and strip the insulation layer at the cable end according to the designed distance. The designed distance here refers to the distance of the first cut. As mentioned above, the distance of the first cut plus the distance of the second cut is the total distance to be cut.

[0059] S20: Fold the shielding net 180 degrees along the direction of the cable insulation;

[0060] S30: Shielding mesh cutting: cut the shielding wire folded on the outer insulation according to the designed size, and half-cut the outer insulation layer under the shielding wire cutting port;

[0061] S40: Pull back the outer insulation to separate the cut outer insulation from the cable body, and fold the remaining shielding wire back under the action of the outer insulation until the length of the folded shielding wire meets the copper ring crimping requirements;

[0062] S50: Copper ring crimping, crimp the copper ring on the cable body and shielding wire. After the copper ring crimping is completed, the outer insulation skin is peeled off;

[0063] S60: The shield mesh is folded back, continuing to bend the shield wire 180 degrees toward the crimped copper ring, ensuring that the shield wire covers the copper ring. This configuration avoids damage to the inner metal foil while also smoothing and temporarily securing the shield wire, improving the reliability and stability of the copper ring crimping and, in turn, increasing the yield rate during wire harness processing.

[0064] Those skilled in the art will appreciate that the present invention is not limited to the foregoing embodiments. The foregoing embodiments and descriptions are merely illustrative of the principles of the present invention. Various changes and modifications may be made to the present invention without departing from the spirit and scope of the present invention. Such changes and modifications are intended to fall within the scope of the present invention. The scope of the present invention is defined by the appended claims and their equivalents.
