[0061] Embodiments of the present invention are described in detail below, examples of which are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are intended to be used to explain the present invention, and should not be construed as limiting the present invention.

[0062] The following is combined with Figures 1 to 10 To describe the double-end sleeve crimping system for electric wires according to an embodiment of the present invention, the double-end sleeve crimping system for electric wires includes a frame 1, a wire feeding device 2, a first transfer device 3, a second transfer device 4, a cutting and stripping device 5, a number tube machine 6, a number tube clamping device 7 and a terminal machine 8.

[0063] The wire feeding device 2 is arranged on the frame 1, and is used for inputting wires. That is to say, the unprocessed wires enter the wire double-end sleeve crimping system through the wire feeding device 2, so that the wires can be passed through the number tube, stripped, crimped with the terminals, etc.

[0064] The first transfer device 3 is disposed on the frame 1 , and clamps the wires input by the wire feeding device 2 to the cutting and stripping device 5 . The first transfer device 3 clamps the wires so as to transport the wires to various workstations for corresponding processing operations.

[0065] The second transfer device 4 is arranged on the frame 1, and the second transfer device 4 clamps one end of the wire. It can be understood that the first transfer device 3 clamps the middle part of the wire, and the second transfer device 4 clamps one end of the wire. The second transfer device 4 is located on one side of the cutting and stripping device 5, and the first transfer device 3 is located on the other side of the cutting and stripping device 5, so that the cutting and stripping device 5 can cut the wire.

[0066] The cutting and stripping device 5 is arranged on the frame 1. The cutting and stripping device 5 cuts the wires and divides the wires into a first wire and a second wire. Accordingly, the first transfer device 3 clamps the first wire so as to transport the first wire to each workstation for corresponding processing operations; the second transfer device 4 clamps the second wire so as to transport the second wire to each workstation for corresponding processing operations.

[0067] The number tube machine 6 is arranged on the frame 1, and the number tube machine 6 prints and cuts the number tube. The number tube machine 6 may include a pre-release wheel, a pre-release wheel detection mechanism, a feeding wheel, a conduit, a cutting device and a nozzle. Among them, the pre-release wheel may use a stepper motor to release the whole bundle of number tubes, and assist the feeding wheel in feeding the tubes; the pre-release wheel detection mechanism may use two sets of photoelectric switches to detect and control whether the pre-release wheel works; the feeding wheel may use a stepper motor to feed the set number tube length; the conduit guides the number tube to ensure the printing position of the number tube respectively; the nozzle prints the set content on the number tube; the cutting device may be driven by a cylinder to cut the number tubes of fixed length. The number tube machine 6 is a prior art and will not be described here.

[0068] The number tube clamping device 7 is arranged on the frame 1, and the number tube clamping device 7 clamps the cut number tube and transports it to the position of the cutting and stripping device 5, so that the first wire and the second wire can be inserted into different number tubes.

[0069] The first transfer device 3 clamps the first wire and inserts the first wire into the number tube, and the second transfer device 4 clamps the second wire and inserts the second wire into another number tube; after the cutting and stripping device 5 strips the first wire and the second wire, the first transfer device 3 clamps the first wire and conveys the first wire to one side of the terminal machine 8, and the second transfer device 4 clamps the second wire and conveys the second wire to the other side of the terminal machine 8; the terminal machine 8 includes a clamping mechanism 81 and a crimping mechanism 82, a first clamping port 811 is provided on one side of the clamping mechanism 81, the first clamping port 811 clamps the first terminal and the first wire, a second clamping port 812 is provided on the other side of the clamping mechanism 81, the second clamping port 812 clamps the second terminal and the second wire, and the crimping mechanism 82 crimps the first terminal and the first wire, the second terminal and the second wire.

[0070] When processing the wires, the cutting and stripping device 5 cuts the wires and divides the wires into a first wire and a second wire, so that the ends of the cut first wire and the ends of the second wire can be processed at the same time, that is, the first transfer device 3 clamps the first wire and inserts the first wire into the number tube, the second transfer device 4 clamps the second wire and inserts the second wire into another number tube, and after the cutting and stripping device 5 strips the first wire and the second wire, the first transfer device 3 clamps the first wire and conveys the first wire to the first clamping port 811 of the terminal machine 8, the second transfer device 4 clamps the second wire and conveys the second wire to the second clamping port 812 of the terminal machine 8, and the crimping mechanism 82 of the terminal machine 8 crimps the wires and the terminals.

[0071] It should be noted that before the wire is cut into the first wire and the second wire, the head end of the wire can be processed first, that is, it can be passed through a number tube, stripped and crimped with a terminal, etc., and then the wire can be cut into the first wire and the second wire. The cut parts can be processed at the same time. After the processing is completed, the end of the wire can also be processed.

[0072] According to some embodiments of the present invention, Figure 3As shown, the wire feeding device 2 includes an X-axis driving mechanism 21, a first Z-axis driving mechanism 22, an upper conveyor belt 23 and a lower conveyor belt 24. The X-axis driving mechanism 21 is connected to the upper conveyor belt 23 and the lower conveyor belt 24, and drives the upper conveyor belt 23 and the lower conveyor belt 24 to rotate in opposite directions. Among them, the X-axis driving mechanism 21 may include a driving wheel, a connecting belt, an upper guide wheel and a lower guide wheel, etc. The X-axis driving mechanism 21 drives the upper guide wheel and the lower guide wheel to rotate through the driving wheel and the connecting belt. The upper guide wheel and the lower guide wheel rotate in opposite directions. The upper guide wheel is connected to the upper conveyor belt 23, and the lower guide wheel is connected to the lower conveyor belt 24, so that the rotation direction of the upper conveyor belt 23 is not used for the rotation direction of the lower conveyor belt 24. The Z-axis driving mechanism 22 is connected to the upper conveyor belt 23 and the lower conveyor belt 24, and drives the upper conveyor belt 23 and the lower conveyor belt 24 to approach or move away from each other, and a conveying groove for conveying wires is formed between the upper conveyor belt 23 and the lower conveyor belt 24.

[0073] That is, when conveying the wires, the wires are placed in the conveying trough, the Z-axis driving mechanism 22 drives the upper conveyor belt 23 to approach the lower conveyor belt 24 to clamp the wires, and the X-axis driving mechanism 21 drives the upper conveyor belt 23 and the lower conveyor belt 24 to rotate to move the wires forward.

[0074] In some examples, such as Figure 4 As shown, the first conveying device 3 may include a wire clamping assembly 31 and a mobile driving assembly 32, the mobile driving assembly 32 is connected to the wire clamping assembly 31 to drive the wire clamping assembly 31 to move; the wire clamping assembly 31 has a first clamping member 311, a second clamping member 312 and a driving member 313, the first clamping member 311 is suitable for clamping the wire, the second clamping member 312 is located in front of the first clamping member 311, and the driving member 313 is connected to the second clamping member 312 to drive the second clamping member 312 to move along the axial direction of the wire to pull the wire.

[0075] By setting the second clamping member 312 as an auxiliary clamping claw, the area to be processed of the wire can be adjusted at each workstation to ensure that the area to be processed of the wire is a straight line. The second clamping member 312 moves with the wire to each workstation to avoid the need to set up an auxiliary clamping claw separately for each workstation of the wire harness manufacturing equipment; and the wire transfer device can realize the operation of first passing through the number tube and then stripping the wire during the processing of the wire, which can avoid the core of the wire from spreading out when the wire passes through the number tube, thereby ensuring the processing quality of the wire as a whole and reducing the manufacturing cost of the equipment. In this example, the mobile drive component 32 can be a multi-axis module. That is to say, the mobile drive component 32 can be set according to the layout of each workstation of the wire harness manufacturing equipment, so that the mobile drive component 32 can drive the wire clamping component 31 to clamp the area to be processed of the wire to each workstation for processing.

[0076] The structure of the second transfer device 4 is similar to that of the first transfer device 3 , and will not be described in detail here.

[0077] According to a further embodiment of the present invention, Figure 5 As shown, the cutting and peeling device 5 includes a second Z-axis driving mechanism 51, an upper knife seat 52, a lower knife seat 53, an upper cutting knife 54, a lower cutting knife 55, an upper stripping knife 56 and a lower stripping knife 57; the second Z-axis driving mechanism 51 is connected to the upper knife seat 52 and the lower knife seat 53 and drives the upper knife seat 52 and the lower knife seat 53 to approach each other or move away from each other, the upper cutting knife 54 is arranged on the upper knife seat 52 and protrudes from the upper stripping knife 56, the lower cutting knife 55 is arranged on the lower knife seat 53 and protrudes from the lower stripping knife 57, the lower cutting knife 55 is opposite to the upper cutting knife 54, the upper stripping knife 56 is arranged on the upper knife seat 52, and the lower stripping knife 57 is arranged on the lower knife seat 53 and opposite to the upper stripping knife 56.

[0078] When the wire needs to be cut, the second Z-axis driving mechanism 51 drives the upper knife seat 52 and the lower knife seat 53 to approach each other, thereby driving the upper cutter 54 and the lower cutter 55 to approach each other to cut the wire. Since the upper cutter 54 protrudes from the upper stripping knife 56 and the lower cutter 55 protrudes from the lower stripping knife 57, the upper stripping knife 56 and the lower stripping knife 57 cut the wire during cutting.

[0079] In this example, one upper cutter 54 is provided and located in the middle of the upper cutter seat 52, two upper stripping knives 56 are provided, one of which is located on one side of the upper cutter seat 52, and the other upper stripping knives 56 are provided. One lower cutter 55 is provided and located in the middle of the lower cutter seat 53, and two lower stripping knives 57 are provided, one of which is located on one side of the lower cutter seat 53, and the other lower stripping knives 57 are provided. In this way, after the upper cutter 54 and the lower cutter 55 cut the wire, the first transfer device 3 passes the first wire through the number tube and then moves toward one of the upper stripping knives 56 and the lower stripping knives 57 to achieve the first wire stripping, and the second transfer device 4 passes the second wire through the number tube and then moves toward the other upper stripping knives 56 and the lower stripping knives 57 to achieve the second wire stripping.

[0080] like Figure 6 As shown, in order to facilitate the insertion of the cut number tube into the wire, the number tube clamping device 7 may include a third Z-axis driving mechanism 71, a first number tube clamp 72, a second number tube clamp 73 and a first Y-axis driving mechanism 74; the third Z-axis driving mechanism 71 is connected to the first number tube clamp 72 and the second number tube clamp 73 and drives the first number tube clamp 72 and the second number tube clamp 73 to move closer to or away from each other, and the first Y-axis driving mechanism 74 is connected to the third Z-axis driving mechanism 71 and drives the third Z-axis driving mechanism 71 to move along the Y-axis.

[0081] In this example, Figure 7As shown, the first number tube clamping jaw 72 includes a fixing seat 721, a first clamping tooth 722, a second clamping tooth 723 and a third clamping tooth 724; a receiving groove 7211 is formed in the fixing seat 721; the first clamping tooth 722 is arranged in the receiving groove 7211, and the end surface of the first clamping tooth 722 is a first clamping surface 7221; one end of the second clamping tooth 723 can be telescopically arranged in the receiving groove 7211, the other end of the second clamping tooth 723 is a first abutting surface (not shown in the figure), and the side surface of the second clamping tooth 723 is a second clamping surface 7231; one end of the third clamping tooth 724 can be telescopically arranged in the accommodating groove 7211, the other end of the third clamping tooth 724 is a force-applying surface 7241, the upper part of the side surface of the third clamping tooth 724 is a third clamping surface 7242, the third clamping surface 7242, the second clamping surface 7231 and the first clamping surface 7221 jointly define a clamping opening 725, the lower part of the side surface of the third clamping tooth 724 is a second abutting surface 7243, the second abutting surface 7243 abuts against the first abutting surface and can move along the first abutting surface.

[0082] Since one end of the second clamping tooth 723 can be telescopically arranged in the accommodating groove 7211, one end of the third clamping tooth 724 can be telescopically arranged in the accommodating groove 7211, the third clamping tooth 724 is moved by applying force to the force-applying surface 7241 of the third clamping tooth 724, and the second abutting surface 7243 abuts against the first abutting surface, the movement of the third clamping tooth 724 drives the second clamping tooth 723 to move, thereby changing the size of the clamping opening 725 to adapt to different pipe sleeves. When in use, the two pipe sleeve clamping jaws are symmetrically arranged to clamp pipe sleeves of different sizes, thereby making it highly versatile.

[0083] In this example, two first number tube clamps 72 can be provided, and two second number tube clamps 73 can also be provided, so as to facilitate clamping two cut number tubes. The structure of the second number tube clamp 73 is the same as that of the first number tube clamp 72, and will not be repeated here.

[0084] As an example, Figure 8As shown, the terminal machine 8 can also include a second Y-axis driving mechanism 83; the second Y-axis driving mechanism 83 is connected to the clamping mechanism 81 and drives the clamping mechanism 81 to move between a first position and a second position, when in the first position, the clamping mechanism 81 clamps the terminal, and when in the second position, the crimping mechanism 82 crimps the terminal; the clamping mechanism 81 includes a first clamping block 813 and a second clamping block 814, the first clamping block 813 and the second clamping block 814 can approach each other or move away from each other, a first clamping opening 811 is formed between one side of the first clamping block 813 and one side of the second clamping block 814, and a second clamping opening 812 is formed between the other side of the first clamping block 813 and the other side of the second clamping block 814; after the second Y-axis driving mechanism 83 drives the clamping mechanism 81 to move to the second position, the crimping mechanism 82 drives the first clamping block 813 to press the second clamping block 814 to crimp the first terminal and the first wire, and the second terminal and the second wire.

[0085] That is to say, the terminal conveying mechanism of the front-end process can convey the terminal to the terminal machine 8, and can convey the terminal to the first clamping port 811 and the second clamping port 812, for example, the first terminal is conveyed to the first clamping port 811, and the second terminal is conveyed to the second clamping port 812, and then the second Y-axis driving mechanism 83 drives the clamping mechanism 81 to move to the second position, and then the first transfer device 3 inserts the first wire into the first terminal, and the second transfer device 4 inserts the second wire into the second terminal, and finally, the crimping mechanism 82 presses the first clamp 813 tightly against the second clamp 814 to crimp the first terminal and the first wire, and the second terminal and the second wire.

[0086] In order to enable the first clamping opening 811 and the second clamping opening 812 to clamp different types of terminals, such as Fig. 9 As shown, a plurality of first clamping openings 811 of different sizes are formed between one side of the first clamping block 813 and one side of the second clamping block 814, and a plurality of second clamping openings 812 of different sizes are formed between the other side of the first clamping block 813 and the other side of the second clamping block 814. In this example, six first clamping openings 811 are provided, and six second clamping openings 812 are provided, so that twelve different types of terminals can be clamped, which is convenient for crimping with different wires.

[0087] In some examples, the double-end sleeve crimping system for electric wires may further include an output mechanism 9, which includes an output belt 91, an output groove 92 and an output clamping assembly 93. The output belt 91 is rotatably arranged on one side of the frame 1, and the output groove 92 is arranged on one side of the output belt 91. The output clamping assembly 93 clamps and moves one end of the processed wire harness so that the other end of the wire harness moves from the output belt 91 to the output groove 92.

[0088] like Fig.10As shown, the output clamping assembly 93 may include a clamping jaw 931 and a third Y-axis driving mechanism 932. The third Y-axis driving mechanism 932 is connected to the clamping jaw 931 and drives the clamping jaw 931 to move along the Y-axis direction. The output belt 91 can be rotated by a motor. When the processed wire harness is long, the clamping jaw 931 clamps one end of the wire harness so that the other end of the wire harness is on the output belt 91. The rotating output belt 91 drives the wire harness to become straight, and then the third Y-axis driving mechanism 932 drives the clamping jaw 931 to move along the Y-axis direction so that the other end of the wire harness moves from the output belt 91 to the output slot 92, thereby effectively preventing the wire harness from being entangled and facilitating the removal of the wire harness.

[0089] In order to convey the terminals to the terminal machine 8, a feeding device 10 may also be included in this example to facilitate conveying the terminals to the first clamping port 811 and the second clamping port 812 of the terminal machine 8, and then the wires are inserted into the terminals, and the terminal machine 8 crimps the wires and the terminals.

[0090] In summary, the present invention has high flexibility. In the process of clamping the number tube, the number tube clamping device 7 can clamp different types of number tubes. In the crimping terminal, the first wire can be clamped by the first transfer device 3 and transported to each station for processing, and the second wire can be clamped by the second transfer device 4 and transported to each station for processing, thereby achieving the need to replace the clamping jaws and molds, and can be directly universal, and is not limited by the trouble of frequent mold replacement due to a large number of terminal types when crimping wires, and can achieve direct continuous production and processing without stopping.

[0091] A second aspect of the present invention provides a wire processing method, comprising the following steps:

[0092] First, put the wire into the wire feeding device 2, and the wire feeding device 2 feeds the wire;

[0093] Second, the first transfer device 3 clamps the wire input by the wire feeding device 2 to the cutting and stripping device 5;

[0096] Fifth, the number tube threading device 6 prints and cuts the number tube;

[0097] Sixth, the number tube clamping device 7 clamps the cut number tube and transports it to the cutting and peeling device 5;

[0098] Seventh, the first transfer device 3 clamps the first wire and inserts the first wire into the number tube, and the second transfer device 4 clamps the second wire and inserts the second wire into another number tube;

[0099] Eighth, the terminal conveying mechanism conveys the first terminal to the first clamping port 811 of the terminal machine 8, and conveys the second terminal to the second clamping port 812 of the terminal machine;

[0100] 9. The cutting and stripping device 5 strips the first wire and the second wire, the first transfer device 3 clamps the first wire and conveys the first wire to the first clamping port 811 of the terminal machine 8, the second transfer device 4 clamps the second wire and conveys the second wire to the second clamping port 812 of the terminal machine, so that the first clamping port 811 of the terminal machine 8 clamps the first terminal and the first wire, and the second clamping port 812 clamps the second terminal and the second wire;

[0101] Ten, the crimping mechanism 82 of the terminal machine 8 crimps the first terminal and the first electric wire, and the second terminal and the second electric wire.

[0102] When processing the wires, the cutting and stripping device 5 cuts the wires and divides the wires into a first wire and a second wire, so that the ends of the cut first wire and the ends of the second wire can be processed at the same time, that is, the first transfer device 3 clamps the first wire and inserts the first wire into the number tube, the second transfer device 4 clamps the second wire and inserts the second wire into another number tube, and after the cutting and stripping device 5 strips the first wire and the second wire, the first transfer device 3 clamps the first wire and conveys the first wire to the first clamping port 811 of the terminal machine 8, the second transfer device 4 clamps the second wire and conveys the second wire to the second clamping port 812 of the terminal machine 8, and the crimping mechanism 82 of the terminal machine 8 crimps the wires and the terminals.

[0103] In summary, the present invention has high flexibility. In the process of clamping the number tube, the number tube clamping device 7 can clamp different types of number tubes. In the crimping terminal, the first wire can be clamped by the first transfer device 3 and transported to each station for processing, and the second wire can be clamped by the second transfer device 4 and transported to each station for processing, thereby achieving the need to replace the clamping jaws and molds, and can be directly universal, and is not limited by the trouble of frequent mold replacement due to a large number of terminal types when crimping wires, and can achieve direct continuous production and processing without stopping.
