Description

Technical Field

[0002] Wire and cable are indispensable raw materials in the electronics industry; when many wires and cables are in use, wire stripping and terminal riveting are required. For cables with multiple cores, when stripping and terminal crimping, after the outer insulation is stripped by a cutting and stripping machine, the insulation of the ends of multiple strands of core wires is stripped by another wire stripping machine. After the insulation layer of the core wires is stripped, terminals need to be crimped at the ends of the core wires inside each core wire; however, since there are multiple core wires in a cable, in the existing technology, when automatically crimping the terminals, it is impossible to separate each wire, so it is impossible to complete terminal crimping for each core wire one by one; in order to achieve terminal crimping for all core wires, the core wires are separated manually to achieve individual terminal crimping for each core wire.

For those of ordinary skill in the art, the specific meanings of the above terms in the embodiments of the present invention can be understood according to specific situations.

[0034] In one embodiment of the present invention, as Figure 1 shown, a multi-core cable stripping and terminal crimping integrated machine includes a machine base 100, an outer layer stripping mechanism 200, a core wire stripping mechanism 300, a terminal crimping mechanism 400, and a cable conveying mechanism 500 provided on the machine base 100.

[0035] The outer layer stripping mechanism 200 is used to strip the outer insulating skin of the cable, the core wire stripping mechanism 300 is used to strip the insulating skin of the core wire in the cable, and the terminal pressing mechanism 400 is used to press the terminal at the end of each core wire; the cable conveying mechanism 500 is used to convey the cable to the working positions of the outer layer stripping mechanism, the core wire stripping mechanism 300 and the terminal pressing mechanism 400. Specifically, the cable conveying mechanism 500 holds and conveys the cable to the stripping position of the outer layer stripping mechanism 200, and the outer layer stripping mechanism 200 completes the stripping of the outer insulating skin of the cable; the cable conveying mechanism 500 then conveys the cable to the stripping position of the core wire stripping mechanism 300 to complete the stripping of the insulating layer of each core wire; finally, the stripped cable is conveyed to the terminal pressing mechanism 400 to complete the terminal pressing of the core wire.

[0036] Referring to Figures 1 to 4 , the terminal pressing mechanism 400 includes: a terminal machine 410, a positioning seat 420 and a wire combing mechanism 430; the terminal machine 410 is arranged on the machine base 100 and is used to press the terminal at the end of the core wire. The positioning seat 420 is arranged at the front end of the lower die of the terminal machine 410; the wire combing mechanism 430 is arranged on one side of the terminal machine 410, and the two comb teeth of the wire combing mechanism 430 extend above the positioning seat 420; the two comb teeth 431 form a positioning groove. The comb teeth of the wire combing mechanism 430 move obliquely downward to comb and limit the core wires that need to be pressed with terminals. Specifically, during the terminal pressing process, the comb teeth 431 of the wire combing mechanism 430 move obliquely downward to comb and limit the core wires that need to be pressed with terminals, and the core wires that need to be pressed with terminals are separated and positioned by the comb teeth, so that each core wire can be independently pressed with terminals without interference with each other. Therefore, fully automatic wire stripping and terminal pressing can be achieved, replacing manual terminal pressing and improving efficiency.

[0037] Further, referring to Figures 3 to 5The positioning seat 420 includes a body 421, a movable block 422, a positioning plate 423 and a compression spring 424. The body 421 is arranged at the front end of the lower die of the terminal machine 410. A slide groove (not shown in the drawings) is provided on the side of the body 421 close to the lower die, and the movable block 422 is arranged in the slide groove; a blind hole (not shown in the drawings) is provided at the bottom end of the movable block 422, and the upper end of the compression spring 424 extends into the blind hole, and the lower end of the compression spring 424 abuts against the lower die seat of the terminal machine 410. The positioning plate 423 is arranged at the upper end of the movable block 422, and an air avoidance hole 424 is provided on the positioning plate 423, and a limiting rib 425 is provided in the air avoidance hole 424; the comb teeth 431 of the combing mechanism 430 move downward in an inclined manner, and the two comb teeth 431 are located on both sides of the limiting rib 425. In this embodiment, when the wire core is being terminald, the two comb teeth 431 of the combing mechanism 430 are tilted downward, so that a core wire is stuck in the positioning groove formed by the two comb teeth 431; and the core wire is positioned at the top of the limiting rib 425; and when the terminal is riveted to the end of the core wire, the positioning plate 423 is subjected to the punching force of the terminal machine 410, so that the movable block 422 overcomes the elastic force of the compression spring 424 and descends, thereby driving the positioning plate 423 and the core wire to move downward together, so that the terminal can be separated from the terminal strip, thereby completing the terminaling of the wire core.

[0038] Furthermore, a limiting groove is provided on one side of the movable block 422 (as shown in the accompanying drawings), and a limiting pin is provided on one side of the body 421 that extends into the limiting groove. The limiting pin limits the vertical travel of the movable block. In this embodiment, the limiting pin cooperates with the limiting groove to define the formation of the movable block 422 and prevent the movable block 422 from escaping from the chute, thereby limiting the sliding movement of the movable block 422 within the chute.

[0039] Further, refer to Figure 3 and Figure 4The combing mechanism 430 includes a guide seat 432, a slider 433, a pushing mechanism 434, and the comb teeth 431. The guide seat 432 is located on one side of the terminal machine 410. The guide seat 432 is provided with a downwardly inclined guide hole 435. Specifically, the horizontal angle of the guide hole 435 is 20° to 60°; more preferably, the horizontal angle of the guide hole 435 is 45°. One end of the slider 433 extends into the guide hole 435. The upper end of the slider 433 is provided with a connecting piece 436 extending above the positioning seat 420. The comb teeth 431 are provided on the connecting piece 436. The pushing mechanism 434 pushes the slider 433 to slide up and down along the guide hole 435. In this embodiment, the pushing mechanism 434 pushes the slider 433 to slide along the guide hole 435, and then pushes the slider 433 to drive the comb teeth 431 to move obliquely downward, so that a core wire is stuck in the positioning groove formed by the two comb teeth 431, thereby combing and positioning the core wire.

[0040] Further, refer to Figure 4 The guide hole 435 is a square through-hole. The slider 433 passes through the guide hole 435. Sliding guides 440 are provided between the top surface of the slider 433 and the top of the guide hole 435, and between the bottom of the slider 433 and the bottom wall of the guide hole 435. The two ends of the guide hole 435 are provided with limit plates 450 for limiting the two sliding guides 440. The sliding guides 440 include a carrier plate and rollers. The carrier plate is evenly provided with a plurality of directional through-holes. The rollers are provided in each of the directional through-holes. The rollers abut against the slider 433 and the inner wall of the guide hole 435. In this embodiment, the two sliding guides 440 guide the slider 433 and reduce the wear of the slider 433 and the guide seat 432. Specifically, when the slider 433 slides, the rollers roll, thereby reducing the wear.

[0041] Further, the reference Figures 2 to 4 , a vertical groove is provided on the guide seat 432 (not shown in the drawings). The pushing mechanism 434 includes a pushing block 4340 and a connecting member 4341. The pushing block 4340 is slidably arranged in the vertical groove, and the connecting member 4341 is arranged at the upper end of the pushing block 4340. The upper end of the connecting member 4341 is fixedly connected to the lifting slider of the terminal machine 410. A first toggle groove 4342 is provided on one side of the pushing block 4340, and a first toggle roller 4330 is provided on one side of the slider 433 that extends into the first toggle groove 4342; the first toggle groove 4342 forms an angle with the vertical line that is not 90° or 0°, so when the pushing block 4340 slides up and down, the slider 433 can be pushed to slide in the guide hole 435 through the first toggle groove 4342.

[0042] Another embodiment of the first toggle groove 4342 comprises two vertically arranged first chutes and a first arcuate groove; the two first chutes are staggered, with one end of the first arcuate groove connecting to the lower end of one first chute and the other end connecting to the upper end of the other first chute. In this embodiment, when the first toggle roller 4330 passes from one first chute through the first arcuate groove and into the other first chute, the first toggle roller 4330 can push the slider 433 to slide within the guide hole 435.

[0043] Further, refer to Figures 2 to 4 , a second toggle groove 4344 is provided on the other side of the pushing block 4340; a guide groove (not shown) is provided in the positioning seat 420, and a sliding plate 426 is provided in the guide groove.

In this embodiment, when the upper die of the terminal machine 410 moves downward, the second toggle roller 461 is toggled through the second toggle groove 4344, so that the lever mechanism 460 pushes the sliding plate 426 upward, so that the wire-dividing groove formed by the two wire-dividing teeth 427 clamps the core wire of the terminal from the bottom end upward, and separates the remaining core wires to both sides, so as to prevent other wires from interfering with the wire core being terminated during the termination process.

[0044] Furthermore, in one embodiment of the second toggle slot 4344, the second toggle slot 4344 forms an angle with the vertical line that is not 90° or 0°. In this embodiment, when the push block 4340 moves up and down, the second toggle slot 4344 drives the lever 46 to move, thereby pushing the sliding plate 426 to slide up and down.

[0045] Furthermore, another embodiment of the second toggle groove 4344 includes two vertically arranged second chutes and a second arcuate groove; the two second chutes are staggered, with one end of the second arcuate groove connected to the lower end of one second chute, and the other end connected to the upper end of the other first chute. In this embodiment, when the second toggle roller 461 moves from one first chute through the first arcuate groove to the other first chute, the second toggle roller 461 can push the sliding plate 426 to slide within the guide chutes.

[0046] Further, refer to Figures 2 to 4, in another embodiment where the movable plate 426 is provided on the positioning base 420, specifically, a guiding chute is provided inside the positioning base 420, a sliding plate 426 is provided in the guiding chute, two wire separating teeth 427 extend from the upper end of the sliding plate 426, and the outer side of the wire separating teeth 427 is an inclined surface.

One end of the lever mechanism 460 is connected to the sliding plate 426, and the other end of the lever mechanism 460 is connected to the pushing mechanism (not shown in the drawing); the pushing mechanism drives the sliding plate 426 to slide up and down through the lever mechanism 460. In this embodiment, when riveting a terminal to the end of a wire core, the pushing mechanism pushes the lever 460, thereby pushing the sliding plate 426 upward, so that the two wire separating teeth 427 separate the wire cores on both sides of the wire core being riveted with the terminal, avoiding interference during terminal crimping. In this embodiment, the pushing mechanism is a motor mechanism, a cylinder or the lifting slider of the terminal machine 410.

[0047] Further, referring to Figure 7 and Figure 8 , the cable conveying mechanism 500 includes a first electric slide table 510, a second electric slide table 520, a wire feeding mechanism 530, a wire clamping mechanism 540, a support base 550, a servo motor 560 and a ball screw pair 570.

In this embodiment, the wire feeding mechanism 530 conveys the cable to the position of the wire clamping mechanism 540, and the wire clamping mechanism 540 clamps the cable. The first electric slide table 510 and the second electric slide table 520 drive the wire feeding mechanism 530, so that the end of the cable is sequentially conveyed to the stripping position of the outer layer stripping mechanism 200, the stripping position of the core wire stripping mechanism 300, and between the upper die and the lower die of the terminal crimping mechanism 400. When stripping the outer insulating skin of the cable, the wire clamping mechanism 540 clamps the cable; when stripping the insulating skin of the core wire, the wire clamping mechanism 540 clamps the core wire. When crimping the terminal, the wire clamping mechanism 540 clamps the end of the core wire, and the screw of the ball screw pair 570 is rotated by driving the servo motor 560, thereby pushing the support base 550 to move, so that the end of the core wire clamped by the wire clamping mechanism 540 extends between the upper die and the lower die.

Two downwardly extending extensions are provided at both ends of the bottom of the second clamping jaw 547, and a clamping groove is provided at the bottom end of the extension for engaging with the first clamping jaw 546; therefore, after clamping the core wire, the core wire can be located between the two extensions to prevent the core wire from shifting.

[0049] Further, referring to Figure 7 , wire guide tubes 531 are further provided at both ends of the wire feeding mechanism 530, and the centers of the two wire guide tubes 531 are on the same straight line as the centers of the two conveyor belts of the wire feeding mechanism. In this embodiment, the two wire guide tubes 531 play a guiding role for the electric wire. Further, the specific structure of the wire feeding mechanism 530 is described in detail in the patent application with the publication number CN108521104A, so it will not be described in detail in this embodiment.

[0050] Further, referring to Figure 6, the outer layer stripping mechanism 200 includes a mounting frame 210, vertical guide rails 220, an upper sliding seat 230, a lower sliding seat 240, a screw rod 250, a second servo motor 260, an upper cutting knife 270 and a lower cutting knife 280. The mounting frame 210 is provided on the machine base 100, and the two vertical guide rails 220 are symmetrically arranged on the inner side walls of the mounting frame 210. The two ends of the upper sliding seat 230 and the lower sliding seat 240 are respectively connected to the corresponding vertical guide rails 220. The upper end of the screw rod 250 has a left-handed thread, and the lower end has a right-handed thread. The upper sliding seat 230 is provided with a left-handed nut that mates with the left-handed thread, and the lower sliding seat 240 is provided with a right-handed nut that mates with the right-handed thread. The second servo motor 260 is connected to the screw rod 250. The upper cutting knife 270 is provided at the bottom end of the upper sliding seat 230, and the lower cutting knife 280 is provided at the top end of the lower sliding seat 240. The upper cutting knife 270 and the lower cutting knife 280 are both provided with V-shaped cuts that cooperate with each other. In this embodiment, during stripping, the second servo motor 260 drives the screw rod 250 to rotate, causing the upper sliding seat 230 and the lower sliding seat 240 to move towards each other. The upper cutting knife 270 and the lower cutting knife 280 cut a cut in the insulating layer, and then the cable conveying mechanism 500 pulls the cable to move, so as to strip the insulating skin on the outer layer of the cable.

[0051] Further, referring to Figure 6 , an upper cutting-off knife 231 is further provided at the bottom end of the upper sliding seat 230, and a lower cutting-off knife 241 is provided on the lower sliding seat 240. The upper cutting-off knife 231 and the lower cutting-off knife 241 cooperate to cut off the cable. Therefore, before stripping the insulating layer, the cable riveted with terminals is cut off, so as to complete the next cable end crimping. The upper cutting knife 270 and the lower cutting knife 280 are both provided with flat cutting edges. After the cable is cut off, the upper cutting knife 270 and the lower cutting knife 280 cut the cut flat.

[0052] Further, the core wire stripping mechanism 300 is a 3FN air stripper.

[0053] The above are only the preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent replacements, and improvements made within the spirit and principle of the present invention shall be included within the protection scope of the present invention.
