[0024] (III) Beneficial effects

[0025] Compared with the prior art, the present invention provides a processing technology for a high-voltage wire harness shielding braided layer, which has the following beneficial effects:

[0026] 1. The breaking mechanism and the cutting mechanism are coordinated and used alternately. The cutting mechanism first clamps the cable to assist the cable to enter the inner cavity of the male knife. After the cable enters the inner cavity of the male knife, its outer rubber layer will contact the inner cavity of the male knife to achieve fixation; then, the breaking knife opens and retracts, and the transmission mechanism drives the male knife to move, so that it contacts the female knife mechanism, and applies pressure to the cable through the female knife, and finally the shielding braided layer is cut off; when the shielding braided layer of the high-voltage wire harness is cut off, the transmission mechanism drives the cutting mechanism and the high-voltage wire harness to move synchronously and retract. At this time, the breaking knife in the breaking mechanism is used to perform multiple compression and loosening actions on the shielding braided layer. Since the shielding braided layer is a metal wire, it is cross-woven in pairs. The breaking knife presses it and then loosens it, which can cause the shielding braided layer to spread out. Finally, the forward mechanism drives the flipping knife to move along the outer wall of the male knife. Under the push of the male knife, the scattered shielding braided layer gradually separates the cross-woven metal wires in pairs, and finally achieves 0-180° flipping;

[0027] The entire process integrates the cutting of shielding braided mesh and the folding of shielding braided mesh into one, which greatly reduces the area occupied by the equipment and the number of processing stations. The cables do not need to be moved between multiple stations, making the equipment operation more stable, improving the processing efficiency while ensuring the processing accuracy and yield rate.

[0028] 2. By setting up multiple sets of breaking up blades and installing them in a ring between the fixed outer plate and the fixed inner plate, the driving component can drive the multiple breaking up blades to rotate and adjust their angles. On the one hand, different types of cables can be clamped without repeatedly replacing the breaking up blades, thereby further improving the overall processing efficiency; on the other hand, since multiple breaking up blades are arranged in a ring, the breaking up efficiency and breaking up effect are better.

[0029] 3. By installing an elastic rubber layer on the side where the breaking knife contacts the cable, and utilizing the characteristics of the elastic rubber layer and the adsorption holes on its surface, when the breaking knife presses the shielding braided layer, the metal wire of the shielding braided layer is adsorbed. The breaking knife increases the adsorption function, prompting the shielding braided layer to spread out quickly, thereby increasing the breaking speed of the shielding braiding.

[0039] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0040] Example 1

[0041] like Figure 1-Figure 4 As shown, this embodiment proposes a processing technology for a high-voltage wire harness shielding braided layer, comprising the following steps:

[0042] S1, high-voltage wire harness is processed by front-end equipment and the outer skin is removed;

[0043] S2. Insert the high-voltage wire harness into the mother knife mechanism manually or by module;

[0044] S3, after the high-voltage wire harness reaches the designated position, the forward module moves the scattering knife 5 to the middle section of the wire harness, and then the scattering mechanism is activated, and the scattering knife 5 positions and clamps the high-voltage wire harness;

[0045] S4. After the high-voltage wire harness is positioned and fixed, the transmission mechanism drives the cutter mechanism to move, so that the high-voltage wire harness is inserted into the inner cavity of the male knife 11, and then the scattering knife 5 opens and retracts, and the transmission mechanism drives the male knife 11 to move to the front end and contact with the female knife mechanism, and the shielding braided layer is cut off by the clamping force of the two;

[0046] S5, after the shielding braided layer of the high-voltage wire harness is cut off, the cutter mechanism and the high-voltage wire harness are synchronously retreated, and the scattering knife 5 in the scattering mechanism repeatedly compresses and loosens the shielding braided layer to cause the shielding braided layer to spread out; the shielding braided layer is made of metal wires, which are cross-woven in pairs, and the scattering knife 5 compresses it and then releases it, which can cause the shielding braided layer to spread out;

[0047] S6. After the shielding braided layer of the high-voltage wire harness is broken up, the forward module and the breaking mechanism are activated, the breaking knife 5 is opened and retracted, and at the same time the forward mechanism is activated, so that the turning knife 23 drives the shielding braided layer to turn over.

[0048] Specifically, the process includes an installation frame 1, a mother knife mechanism includes a fixed knife plate 2 detachably installed on a side plate of the installation frame 1, a mother knife 3 is installed on the fixed knife plate 2, and a feeding hole 4 connected to the mother knife 3 is opened on one side of the installation frame 1;

[0049] The breaking mechanism includes a driving component and a breaking knife 5. The breaking knife 5 is provided with at least two pieces. The driving component drives the breaking knife 5 to move to compress or loosen the cable.

[0050] The cutting mechanism includes a male knife 11, a turning knife 23 and a connecting seat 20. The male knife 11 can be detachably installed on the connecting seat 20, and the center of the male knife 11 is on the same horizontal line as the center of the female knife 3. The transmission mechanism is used to drive the connecting seat 20 forward and backward. The connecting seat 20 is equipped with a forward mechanism, which is used to drive the turning knife 23 to slide along the outer wall of the male knife 11.

[0051] As an embodiment of the present invention, the scattering mechanism is a component that fully clamps the shaft-shaped part, and the clamping part is the scattering knife 5. In the present invention, the scattering mechanism and the cutting knife mechanism are used in coordination, and the two are used alternately. The cutting mechanism first clamps the cable to assist the cable to enter the inner cavity of the male knife 11. After the cable enters the inner cavity of the male knife 11, its outer rubber layer will contact the inner cavity of the male knife 11 to achieve fixation; then, the scattering knife 5 opens and retracts, and the transmission mechanism drives the male knife 11 to move, so that it contacts the female knife mechanism, and applies pressure to the cable through the female knife 3, and finally achieves the shielding braiding. layer; when the shielding braided layer of the high-voltage wire harness is cut off, the transmission mechanism drives the cutting knife mechanism and the high-voltage wire harness to move synchronously back. At this time, the breaking knife 5 in the breaking mechanism is used to perform multiple compression and loosening actions on the shielding braided layer. Since the shielding braided layer is a metal wire, which is cross-woven in pairs, the breaking knife 5 compresses it and then loosens it, which can cause the shielding braided layer to spread out. Finally, the forward mechanism drives the turning knife 23 to move along the outer wall of the male knife 11. Under the push of the male knife 11, the scattered shielding braided layer, the cross-woven metal wires in pairs, are gradually separated, and finally a 0-180° flip is achieved.

[0052] The driving components in this embodiment can be two cylinders, which respectively drive the two breaking knives 5 to move closer or apart. Of course, the combined shape of the breaking knives 5 is compatible with the cables. This is a conventional setting in the prior art and will not be repeated here.

[0053] The entire process integrates the cutting of shielding braided mesh and the folding of shielding braided mesh into one, which greatly reduces the area occupied by the equipment and greatly improves the processing efficiency.

[0054] It should be noted that in the actual processing process, it is necessary to process the shielding braided layers of cables of different types. In order to ensure that the equipment is compatible with a variety of high-voltage wiring harnesses, the female knife 3 and the male knife 11 are generally detachably installed; of course, the blades in the ordinary breaking mechanism also need to be replaced according to different types of wiring harnesses.

[0056] refer to Figure 5-Figure 7 , a processing technology for a shielded braided layer of a high-voltage wire harness, the breaking up mechanism also includes a fixed outer plate 6 and a fixed inner plate 7, a plurality of breaking up knives 5 are arranged, and the plurality of breaking up knives 5 are annularly installed between the fixed outer plate 6 and the fixed inner plate 7 through a pin shaft 8, and at least two pin shafts 8 are provided, one of which fixes the five breaking up knives on the fixed outer plate 6, and the other pin shaft 8 connects the five breaking up knives and the fixed inner plate 7, and a driving component is used to drive the fixed inner plate 7 to rotate. When the fixed inner plate 7 rotates, the pin shaft 8 on the fixed inner plate 7 drives the breaking up knife 5 to rotate around the pin shaft 8 on the fixed outer plate 6 to adjust the angle of the breaking up knife 5.

[0057] As another preferred embodiment of the present invention, a breaking up mechanism is provided, and a driving component can drive multiple breaking up knives 5 to rotate and adjust their angles. On the one hand, different types of cables can be clamped without repeatedly replacing the breaking up knives 5, thereby further improving the overall processing efficiency. On the other hand, since the breaking up knives 5 are arranged in a ring shape with multiple pieces, preferably ten pieces, and a cutting method with ten ring knives is adopted, the breaking up efficiency and breaking up effect are better, the yield rate is greatly improved, the equipment operation is more stable, and the processing accuracy and yield rate are guaranteed.

[0060] Specifically, the driving components include a right-angle reducer 10 and a cam-connecting rod mechanism, the cam-connecting rod mechanism includes a fixed plate 12 and two connecting rods 13, and the two connecting rods 13 are hinged to the fixed plate 12; the right-angle reducer 10 is installed on the linear module, and the output shaft of the right-angle reducer 10 drives the connected fixed plate 12, and fixed ears 14 are installed on the opposite sides of the fixed inner plate 7, and the two connecting rods 13 are respectively connected to the fixed ears 14.

[0061] The present invention provides a specific implementation of the driving component, which uses a right-angle motor as a power source and drives the fixed inner plate 7 to rotate through a cam-link mechanism, thereby adjusting the angles of the breaking knives 5.

[0062] It should be noted that the driving component can also be other forms, such as installing a motor on the outside of the fixed outer plate 6, installing a transmission gear on the inside thereof, and setting a rotating gear on the edge of the fixed inner plate 7. The transmission gear is driven by the motor, thereby driving the rotating gear to rotate, and the fixed inner plate 7 can also be rotated.

[0063] Of course, the rotation angle of the fixed inner plate 7 can be directly adjusted by the main machine. In order to prevent the fixed inner plate 7 from rotating too much, a limit hole can be opened on the fixed inner plate 7 so that the pin shaft 8 connected to the fixed outer plate 6 passes through the limit hole. The limit hole can be used to limit the rotation degree of the fixed inner plate 7. This is a conventional means in the prior art and will not be repeated here.

[0064] Specifically, the forward mechanism includes a flip cylinder 15 and a transmission plate 16 . The transmission plate 16 is slidably installed outside the male knife 11 , and the telescopic end of the flip cylinder 15 is fixedly connected to the transmission plate 16 .

[0070] In this embodiment, the breaking up mechanism is further optimized so that the breaking up knife 5 has an adsorption function, and an elastic rubber layer 24 is installed on the side of the breaking up knife 5 that contacts the cable.

[0071] Furthermore, it is determined that the elastic rubber layer 24 is detachably connected to the inclined surface, and at the same time, the adsorption hole 25 penetrates the body of the elastic rubber layer 24 , so that dust and debris in the adsorption hole 25 can be easily cleaned.
