The debugging efficiency is low, which is not conducive to the rapid production of the factory and results in low shipping efficiency of the automated equipment. Summary of the Invention

Therefore, they cannot be understood as limitations on the present invention.

[0059] In the description of the present invention, "several" means one or more, "many" means more than two, "greater than," "less than," and "exceed" are understood to exclude the number itself, while "above," "below," and "within" are understood to include the number itself.

[0060] Reference Figures 1 to 6 The twisted-pair machine is provided with a second direction and a first direction which are orthogonal to each other, and the second direction and the first direction are both set to be horizontal directions. The twisted-pair machine is used to process four wires at the same time to produce two sets of twisted-pair wires.

[0061] The two ends of the wire are set as end A and end B respectively.

[0062] The twisted-pair machine includes: a frame 100 , a wire pulling assembly 200 , a cutting and stripping device 300 , an end processing assembly, a twisting device 700 and a handover and transportation assembly 500 .

[0063] The cutting and peeling device 300 includes a knife group and a cutting drive device.

[0064] The number of knife groups is set to two, and the two knife groups are arranged in the vertical direction. The blades of the two knife groups are arranged opposite each other. Specifically, the knife group includes a stripping knife and a cutting knife. The number of stripping knives is set to two, and the two stripping knives are respectively arranged on both sides of the cutting knife in the first direction. The cutting knife is used to break the wire.

[0065] The stripping knife is used to make an incision for the outer skin of the wire and to limit the outer skin of the wire. Then, other components are used to pull the wire away from the cutting and stripping device 300 to achieve wire stripping.

[0066] Specifically, in this embodiment, the cutting drive device is configured as a structure of a servo motor + bidirectional screw + slide, and the number of slides is set to two. The two slides are respectively fixed relative to the two knife groups, and the two slides are respectively threadedly connected to the two ends of the bidirectional screw. The bidirectional screw is driven to rotate by the servo motor, so that the two slides are moved closer to or away from each other, thereby driving the two knife groups to move closer to or away from each other.

[0067] In other embodiments, the number of cutting drive devices can also be set to two, and the two cutting drive devices are set in one-to-one correspondence with the two knife groups. The two cutting drive devices drive the two knife groups to move closer to or away from each other to complete the cutting and stripping of the wire.

[0068] Specifically, in this embodiment, the wire pulling assembly 200 includes a clamping jaw up and down driving device 210 , a clamping jaw lateral movement driving device 220 , an end clamping jaw 230 , a wire pulling driving member 240 and a wire pulling clamping jaw 250 .

[0069] The jaw vertical drive device 210 is fixedly mounted on the frame 100. The jaw vertical drive device 210 is configured as a linear cylinder. In other embodiments, the jaw vertical drive device 210 can also be configured as a conventional linear drive device such as a linear motor. The jaw vertical drive device 210 is used to drive the jaw traverse drive device 220 and the end jaw 230 in the vertical direction to prevent the end jaw 230 from obstructing other components.

[0070] The clamping jaw transverse movement driving device 220 is installed at the output end of the clamping jaw up and down driving device 210. The clamping jaw transverse movement driving device 220 is a linear cylinder.

[0071] The end clamping jaws 230 are mounted on the output end of the clamping jaw traverse driving device 220. The end clamping jaws 230 are configured as conventional pneumatic clamping jaws. Specifically, the number of the end clamping jaws 230 is configured as two, and the two end clamping jaws 230 are respectively used to clamp two groups of wires.

[0072] The wire drive 240 is fixedly mounted on the frame 100. Specifically, in this embodiment, the wire drive 240 is configured as a belt-type electric linear drive device. In other embodiments, the wire drive 240 may also be configured as other linear drive devices, and those skilled in the art may select the appropriate one based on actual needs. The wire drive 240 is used to drive the wire clamp 250 to move in a first direction.

[0073] The wire pulling clamp 250 is arranged on the side of the end clamp 230 away from the cutting and peeling device 300, and the wire pulling clamp 250 is fixedly installed on the output end of the wire pulling drive 240. The wire pulling clamp 250 is a conventional cylinder clamp, and the wire pulling clamp 250 is fixedly installed on the output end of the wire pulling drive 240.

[0074] When the wire pulling clamp 250 pulls the wire, the wire pulling clamp 250 first moves to the bottom of the end clamp 230. At this time, the end clamp 230 is lifted by the clamp up and down drive device 210 and is in a higher position to avoid the end clamp 230 hindering the normal operation of the wire pulling clamp 250. Then the wire pulling clamp 250 clamps the B end of the wire and pulls the B end away from the cutting and stripping device 300. Then the clamp up and down drive device 210 drives the clamp transverse drive device 220 and the end clamp 230 to move in the up and down directions. When the wire is pulled to the specified length, the wire pulling clamp 250 stops moving, the end clamp 230 clamps the A end of the wire, and the cutting and stripping device 300 works to cut the wire. After the wire is cut, the clamp transverse drive device 220 drives the end clamp 230 to move in the first direction, so that the end clamp 230 moves away from the cutting and stripping device 300, so as to drive the A end away from the cutting and stripping device 300, thereby achieving the stripping of the A end. The stripping of the B end is done through other structures.

[0075] The number of the end processing assemblies is set to two sets. Specifically, in this embodiment, the two sets of end processing assemblies are arranged along the second direction, and the two sets of end processing assemblies are symmetrically arranged about the center of the cutting and peeling device 300.

[0076] Placing the two sets of end processing components on the same side of the twisted pair machine can facilitate installation, debugging and maintenance by the staff of the twisted pair machine manufacturer, thereby improving debugging efficiency, which is more conducive to rapid production in the factory and thus improving the shipping efficiency of the equipment.

[0077] The two sets of end processing components are respectively configured as a second end processing component and a first end processing component.

[0078] Specifically, the terminal processing assembly includes a main transport assembly, a terminal crimping machine 420, and a visual inspection device 430. The terminal crimping machine 420 and the visual inspection device 430 are arranged along the second direction, with the terminal crimping machine 420 positioned on the side of the visual inspection device 430 away from the cutting and stripping device 300. The visual inspection device of the second terminal processing assembly is configured as a second visual inspection device, while the visual inspection device of the first terminal processing assembly is configured as a first visual inspection device.

[0079] The main transport assembly includes a lifting drive member 413 , an actuating head 415 and a transport actuator 414 .

[0080] Specifically, in this embodiment, the transport actuator 414 is configured as a conventional screw-type electric linear drive device. In other embodiments, those skilled in the art may select the specific model and drive mode of the transport actuator 414 according to actual needs. The transport actuator 414 is used to drive the actuating head 415 to move along the second direction.

[0081] Specifically, in this embodiment, the lifting drive member 413 is configured as a linear cylinder. In other embodiments, those skilled in the art may select the specific model and driving mode of the lifting drive member 413 according to actual needs. The lifting drive member 413 is used to drive the operating head 415 to move in the up and down directions.

[0082] By setting up a lifting drive member 413, after the terminal is crimped, the lifting drive member 413 drives the action head 415 to move upward away from the lower mold of the terminal crimping machine 420, thereby reducing the wear of the lower mold; it can also prevent the end of the wire from being blocked by the lower mold, thereby preventing the wire from being excessively bent and affecting the normal progress of subsequent inspections and twisting processes.

[0083] Specifically, in this embodiment, the number of the lifting drive member 413 and the number of the actuating head 415 are both set to two, and the lifting drive member 413 and the actuating head 415 are arranged in a one-to-one correspondence. The lifting drive member 413 is fixedly mounted at the output end of the transport actuator 414, and the actuating head 415 is fixedly mounted at the output end of the lifting drive member 413. In other embodiments, the number of the lifting drive member 413 can be set to one, and both actuating heads 415 are mounted at the output end of the lifting drive member 413. Alternatively, the number of the actuating head 415 and the number of the lifting drive member 413 can be set to one. Alternatively, the number of both actuating heads 415 and the lifting drive member 413 can be set to multiple to accommodate the need for simultaneous processing of more twisted pairs.

[0084] The main transport component of the first end processing component is set as the first transport component, and the main transport component of the second end processing component is set as the second transport component.

[0085] Specifically, in this embodiment, the first transport assembly further includes a first stripping and disengaging drive device 411, which is disposed between the lifting drive member 413 and the transport actuator 414. When the cutting and stripping device 300 operates, the wire is cut. After the wire is cut, the first stripping and disengaging drive device 411 drives the lifting drive member 413 and the main operating head 415 of the first transport assembly to move in a first direction, moving the main operating head 415 of the first transport assembly away from the cutting and stripping device 300, thereby moving the B end away from the cutting and stripping device 300, thereby achieving stripping of the B end.

[0086] Specifically, in this embodiment, the action head 415 of the first transport assembly is configured as a wire feeding mechanism. Specifically, in this embodiment, the wire feeding mechanism includes a wire feeding frame 610 , a roller assembly 620 and a wire sleeve 630 .

[0087] The wire feeding frame 610 is fixedly connected to the output end of the transport actuator 414 of the first transport assembly, and the transport actuator 414 drives the wire feeding frame 610 to move along the second direction.

[0088] The wire sleeve 630 is fixedly connected to the wire feeding frame 610, and the roller assembly 620 is arranged on the side of the wire sleeve 630 away from the cutting and stripping device 300. The wire sleeve 630 is used to support and guide the wire, and the roller assembly 620 is used to adjust the tension of the wire and guide the wire.

[0089] Specifically, in this embodiment, the roller assembly 620 includes a plurality of wire feeding rollers 621 , a wire feeding adjustment mechanism 622 , and a wire feeding adjustment block 623 .

[0090] Multiple wire feed rollers 621 are arranged in two rows, one above the other. The two rows of wire feed rollers 621 are configured as a second roller group and a first roller group, respectively. The first roller group is mounted on and rotatably connected to the wire feed frame 610. The second roller group is positioned above the first roller group and is mounted on and rotatably connected to the wire feed adjustment block 623.

[0091] The wire feeding adjustment mechanism 622 includes an up and down adjustment structure 6221 , a swing adjustment structure 6222 and a reset member.

[0092] The wire feeding adjustment block 623 is connected to the wire feeding frame 610 by a rotating shaft so that the wire feeding adjustment block 623 can move up and down relative to the wire feeding frame 610 and can rotate at a certain angle relative to the wire feeding frame 610.

[0093] The reset member is disposed between the wire feeding frame 610 and the wire feeding adjustment block 623 , and the reset member enables the wire feeding adjustment block 623 to have an upward movement tendency relative to the wire feeding frame 610 .

[0094] The up-down adjustment structure 6221 includes an up-down adjustment knob and an up-down adjustment screw, wherein the up-down adjustment knob is threadedly connected to the up-down adjustment screw. The up-down adjustment structure 6221 is used to adjust the position of the swing adjustment structure 6222 in the up-down direction.

[0095] The swing adjustment structure 6222 includes a swing adjustment knob 641 and a swing adjustment eccentric wheel 642. The swing adjustment knob 641 is used to drive the swing adjustment eccentric wheel 642 to rotate. The outer peripheral surface of the swing adjustment eccentric wheel 642 is a cylindrical surface.

[0096] An eccentric groove is formed at the upper end of the wire feed adjustment block 623, and the swing adjustment eccentric 642 engages with the eccentric groove. The outer peripheral surface of the swing adjustment eccentric 642 is configured as a cylindrical surface, so that the swing adjustment eccentric 642 always abuts against the eccentric groove during rotation, thereby adjusting the tilt angle of the wire feed adjustment block 623. This creates a certain height difference between the two rollers of the second roller assembly in the vertical direction, resulting in two changes in the tension of the wire when passing through the roller assembly 620. This avoids poor wire feeding due to only a single change in the wire tension, thereby enabling the roller assembly 620 to better feed the wire.

[0097] In addition, the spacing between the rollers close to the cutting and stripping device 300 can be set to be smaller than the spacing between the rollers far away from the cutting and stripping device 300, so as to better clamp the wire to avoid the wire being accidentally pulled out a certain distance when the roller assembly 620 is away from the cutting and stripping device 300, thereby avoiding affecting the normal progress of subsequent steps.

[0098] Specifically, in this embodiment, the wire feeding frame 610 is further provided with scale lines for indicating the position of the wire feeding adjustment block 623 .

[0099] Specifically, in this embodiment, the number of second transport assemblies is set to two, and the two second transport assemblies are arranged along the first direction, and the two second transport assemblies are respectively used to clamp the A end and the B end of the wire. In other embodiments, the number of second transport assemblies may be set to three, four, or other numbers. Those skilled in the art can select the number of second transport assemblies according to actual needs.

[0100] Specifically, in this embodiment, the actuating head 415 of the second transporting component is configured as a clamp. Specifically, the actuating head 415 of the second transporting component is configured as a cylinder clamp, a fixed block is provided in the middle of the cylinder clamp, and clamping units are provided on both sides. The two clamping units are approached or moved away from the fixed block provided in the middle at the same time through a pneumatic structure, thereby achieving simultaneous clamping of two wires.

[0101] In other embodiments, the actuating head 415 may also be configured as a structure formed by a combination of two independently controlled clamping jaws. Those skilled in the art may select the specific structure of the actuating head 415 according to actual needs.

[0102] The wire stranding device 700 includes a wire stranding rotating motor 710 , a wire stranding clamp 720 , a wire stranding guide structure 730 and a wire stranding forward pushing device 740 .

[0103] The wire twisting rotation motor 710 and the wire clamping forward pushing device 740 are both fixedly mounted on the frame 100. Specifically, in this embodiment, the wire clamping forward pushing device 740 is configured as a linear cylinder. In other embodiments, the wire clamping forward pushing device 740 can also be configured as a conventional linear drive device such as a linear motor.

[0104] The stranded wire clamp 720 and the stranded wire guide structure 730 are arranged along a first direction. The stranded wire clamp 720 is disposed on a side of the stranded wire guide structure 730 away from the stranded wire rotating motor 710 and the stranded wire clamping and pushing device 740 .

[0105] A guide conical surface 731 is provided on one side of the stranded wire guide structure 730 close to the stranded wire clamping jaw 720 .

[0106] The stranded wire clamping claw 720 includes a clamping claw mounting body 721 and a stranded wire clamping structure 722. The stranded wire clamping structure 722 is hinged to the clamping claw mounting body 721. The number of the stranded wire clamping structures 722 is set to two. The two stranded wire clamping structures 722 are respectively arranged on both sides of the stranded wire clamping claw 720. The end of the stranded wire clamping structure 722 close to the stranded wire guide structure 730 is set as a clamping guide part 7222, and the end away from the stranded wire guide structure 730 is set as a stranded wire clamping part 7221. The stranded wire clamping part 7221 and the clamping guide part 7222 are respectively arranged on both sides of the hinge of the stranded wire clamping structure 722.

[0107] The clamping guide portion 7222 is configured to cooperate with the guide conical surface 731 so that when the stranded wire clamping structure 722 approaches the stranded wire guide structure 730, the two stranded wire clamping jaws 720 move toward each other. In other embodiments, the two stranded wire clamping jaws 720 may move away from each other when the stranded wire clamping structure 722 approaches the stranded wire guide structure 730.
