Description

[Technical field]

[0001] The present invention relates to the technical field of wire harness crimping, and more particularly to a wire harness crimping machine for new energy vehicles. [Background technology]

[0002] Crimping is a method to connect a wire harness and a terminal. In the crimping process, a certain mechanical external force is applied to strip the insulation of the wire harness, and the crimp terminal is clamped to the conductor. The raw terminal, wire harness, and waterproof plug are manufactured into a semi-finished wire harness by using a mold and crimping equipment, and electricity can be transmitted from the wire harness to the terminal by crimping.

[0003] In the prior art, when crimping a wire harness to a terminal, in a situation where the wire harness insulation is stripped off, the copper wire harness may bend after the insulation is stripped off. In other words, a bending point exists between the copper wire from which the insulation layer has been stripped off and the end of the stripped copper wire, and a gap is likely to occur between the terminal and the insulation after the terminal and the wire harness are crimped. In addition, in some copper wire harnesses, the copper wires are displaced from their correct positions in the copper wire harness, causing misalignment, which causes a problem that the copper wire harness cannot be inserted smoothly and tightly into the terminal.

[0019] As shown in Figs. 1 to 16, this embodiment proposes a wire harness crimping machine for new energy vehicles, which includes a frame 1, a crimping blade 2, a crimping table 42, and a mounting plate 4, a lifting drive member is attached to the frame 1, the crimping blade 2 is attached to the lifting drive member, the crimping table 42 is attached to the frame 1 and is located below the crimping blade 2, and the mounting plate 4 is attached to the frame 1, The bending correction mechanism and the feed fixing mechanism are further provided. The bend correction mechanism includes: Three arc-shaped pressing plates 13 are provided, arranged at equal intervals in a ring shape and attached to the mounting plate 4; and a drive assembly that is attached to the frame 1, is connected to the arc-shaped pressure plates 13, and controls the three arc-shaped pressure plates 13 to move toward the center simultaneously, applying a pressing force to the copper wire bending points to flatten the copper wire harness.

[0020] In this embodiment, the copper wire harness after the insulation is stripped and bent is controlled by the feeding and fixing mechanism to move the bending point on the copper wire harness to the center point of three arc-shaped pressing plates 13. Thereafter, under the control of the driving assembly, the arc-shaped pressing plates 13 gradually approach the copper wire harness until the inner surface of the arc-shaped pressing plates 13 comes into close contact with the copper wire harness. The pressing force formed between the arc-shaped pressing plates 13 gradually reduces the bending angle of the copper wire harness until it disappears, thereby straightening the bent copper wire harness and avoiding the phenomenon of a gap between the terminals and the insulator after the wire harness and the terminals are crimped. After being flattened, the drive assembly controls the arc-shaped pressure plate 13 to gradually move away from the copper wire harness, and at the same time, the feed and fix mechanism controls the copper wire harness to be inserted into the terminal. After the part of the copper wire harness that is to have its insulation stripped is completely inserted into the terminal, it is at the position of the crimping table 42, and the lifting drive member controls the downward movement of the crimping blade 2 to crimp the terminal and the wire harness.

[0021] The drive assembly includes: A first motor 9 attached to the frame 1; a first bevel gear 10 fixedly connected to an output shaft of the first motor 9; A rotating table 6 is rotatably mounted on the mounting plate 4 and has a through hole at its center; A first bevel gear ring 11 is attached to the rotating table 6 on a side close to the pressure contact blade 2 and meshes with the first bevel gear 10; a helical thread 7 attached to the rotating table 6 on the side away from the pressure contact blade 2; Three limiting blocks 8 are provided, which are attached to the mounting plate 4 at equal intervals in an annular shape and have through holes drilled thereon; Three of them are provided, each of which is slidably fitted into the through holes of the three limiting blocks 8, and the three arc-shaped pressure plates 13 are attached thereon, and the first gear rack 12 is connected to the spiral rib 7 so as to be capable of transmitting power.

[0022] In this embodiment, the feeding and fixing mechanism moves the copper wire harness to the center point of the three arc-shaped pressing plates 13, and then the first motor 9 supplies power to rotate the first bevel gear 10, and the first bevel gear ring 11 meshed with the first bevel gear 10 rotates due to the rotation of the first bevel gear 10, and the rotation of the first bevel gear ring 11 simultaneously rotates the rotating table 6, and at the same time, the helical thread 7 moves simultaneously with the rotation of the rotating table 6, and the movement of the rotating table 6 and the helical thread 7 causes the first gear rack 12 to approach the copper wire harness within the limiting block 8. When the first gear rack 12 approaches the copper wire harness, the arc-shaped pressing plate 13 approaches the copper wire harness, and the three arc-shaped pressing plates 13 approach the copper wire harness at the same time. When they contact the copper wire harness, a pressing force is generated on the copper wire harness. Due to the pressing force of the arc-shaped pressing plates 13 against the copper wire harness, the bending angle at the bending point is gradually reduced, the copper wire harness becomes straight, and the subsequent crimping of the copper wire harness and the terminals is facilitated.

[0023] A combing reversal mechanism is also provided, the combing reversal mechanism being: Two second slide rails 14 are provided, which are symmetrically attached to the mounting plate 4 and have triangular insertion grooves formed thereon; Two slide blocks 15 are provided, each of which is slidably mounted in the two second slide rails 14 and has a rectangular groove formed thereon; Two support plates 16 are provided, which are attached to the two slide blocks 15 and have an arc-shaped structure; a hollow cylinder 23 rotatably mounted between the two support plates 16, with two abutment strips provided on its outer ring surface, the support plate 16 being positioned between the two abutment strips on the outer ring surface of the hollow cylinder 23, with the inner ring surface of the support plate 16 contacting the outer ring surface of the hollow cylinder 23, the hollow cylinder 23 gradually decreasing in diameter from the end remote from the mounting plate 4 to the end close to the mounting plate 4, and with a plurality of sliding grooves provided on the inner ring surface of the hollow cylinder 23; a clamping and coaming assembly connected to the hollow cylinder 23; and a reversing assembly connected to the hollow cylinder 23 to allow the copper wire harness to rotate as it is combed.

[0024] The clamp-combing assembly comprises: A plurality of combing posts 24 are provided, arranged at equal intervals in an annular shape, and slidably fitted in the sliding groove of the hollow cylinder 23, with the end close to the hollow cylinder 23 being circular and the end away from the hollow cylinder 23 being conical; A plurality of circular through holes are drilled thereon, the combing post 24 is slidably fitted into the circular through holes of the connecting ring 25, and a connecting ring 25 is drilled with an annular sliding path at an end remote from the mounting plate 4; a first spring support 26 provided in plurality, attached in an annular shape at equal intervals on the outer ring surface of the connecting ring 25, and connected to the combing post 24 so as to be capable of transmitting power; Two elastic extensible rods 27 are provided and symmetrically attached to the connecting rings 25; Two arc-shaped pressing plates 28 are provided and attached to the respective extension ends of the two elastic extension rods 27; Two of them are provided and are attached to the telescopic ends of the two elastic telescopic rods 27 respectively, and the conical ends of the combing posts 24 are positioned within the control rings 29.

[0025] A first electric telescopic rod 31 is provided in two, attached to the two second slide rails 14, and has a circular stopper plate at its telescopic end, the circular stopper plate on which is located within the annular sliding path of the connecting ring 25; Four elastic members 21 are provided, each of which is attached in pairs to the rectangular groove of the slide block 15; The slide block 15 further includes two locking blocks 22 attached to the extension ends of the two sets of elastic members 21 and slidably fitted in the rectangular grooves of the slide block 15.

[0026] The inversion assembly includes: Two mounting posts 17 are provided and attached to the two slide blocks 15 on the sides close to the mounting plate 4, respectively; Two first spur gears 18 are provided, each of which is rotatably provided on an opposite side of the two mounting posts 17, and each of which is rotatably disposed on the mounting posts 17 via a rotation shaft; two second bevel gears 19 are provided, each of which is rotatably provided on the opposing side of the two mounting posts 17, and are rotatably disposed on the mounting posts 17 via a rotation shaft, and the rotation shaft of the second bevel gear 19 is connected and fixed to the rotation shaft of the first spur gear 18 located between the mounting posts 17 and the second bevel gear 19; Two second gear racks 20 are provided, each attached to the bottom of the two second slide rails 14 on the opposing sides, and the upper side of the second gear rack 20 is meshed with the first spur gear 18; and a second bevel gear ring 30 attached to the end of the hollow cylinder 23 close to the mounting plate 4 and meshed with the two second bevel gears 19.

[0027] In this embodiment, when each copper wire is deviated from the correct position in the copper wire harness, the feeding and fixing mechanism clamps the insulation layer of the wire harness and moves the end of the copper wire close to the insulation layer to the center point of the connecting ring 25, and then the first electric telescopic rod 31 extends to move the connecting ring 25 in the direction approaching the mounting plate 4. The movement of the connecting ring 25 causes the combing post 24 to slide in the sliding groove of the hollow cylinder 23 toward the other end of the hollow cylinder 23. During the sliding process of the combing post 24, because the diameters of both ends of the hollow cylinder 23 are different, the combing post 24 moves toward the center of the connecting ring 25. That is, when the combing post 24 approaches the copper wire harness, a compression effect is generated in the spring on the first spring bearing 26, and when the combing post 24 approaches the copper wire harness, the control ring 29 approaches the copper wire harness, and when the control ring 29 approaches the copper wire harness, the elastic telescopic rod 27 is extended, and the extension of the elastic telescopic rod 27 causes the two arc-shaped pressing plates 28 to approach the center point of the connecting ring 25 at the same time, sandwiching the copper wire harness, and the conical tips of the combing post 24 are inserted into the gaps between the copper wires. During the process in which the first electric telescopic rod 31 slides the combing post 24 from one end to the other end of the hollow cylinder 23, the locking block 22 is in the insertion groove away from the mounting plate 4 of the second slide rail 14, so that the slide block 15 does not slide in the second slide rail 14 during this process. When the combing post 24 slides to the end of the hollow cylinder 23 close to the mounting plate 4, the elastic member 21 is compressed and shortened due to the extension of the first electric telescopic rod 31, causing the locking block 22 to leave the insertion groove of the second slide rail 14. After the locking block 22 leaves the insertion groove of the second slide rail 14, the first electric telescopic rod 31 extends, causing the slide block 15 to slide within the second slide rail 14 in a direction approaching the mounting plate 4. The movement of the slide block 15 moves the support plate 16, and the movement of the support plate 16 moves the hollow cylinder 23, so that the clamp and combing assembly moves in a direction approaching the mounting plate 4.Furthermore, as the slide block 15 moves, the mounting post 17 moves on the second slide rail 14, and as the mounting post 17 moves, the first spur gear 18 moves and meshes with the second gear rack 20, so that the first spur gear 18 rotates while moving, and the rotation of the first spur gear 18 rotates the second bevel gear 19, and the rotation of the second bevel gear 19 rotates the second bevel gear ring 30, and the rotation of the second bevel gear ring 30 rotates the hollow cylinder 23, and the rotation of the hollow cylinder 23 rotates the combing post 24, and the rotation of the combing post 24 rotates the connecting ring 25 and the arc-shaped pressing plate 28, and the rotation of the arc-shaped pressing plate 28 rotates the clamped copper wire harness, so that the combing effect of the combing post 24 and the rotation effect of the arc-shaped pressing plate 28 gradually return each of the misaligned copper wires from their scattered state to their bundled state. After the copper wire harness is combed, the first electric telescopic rod 31 is again in an extended state, and when the slide block 15 slides into the insertion groove at the end close to the mounting plate 4 on the second slide rail 14 and the locking block 22 enters the insertion groove, the first electric telescopic rod 31 contracts, causing the tether ring 25 to move in the hollow cylinder 23 from the end close to the mounting plate 4 to the end remote from the mounting plate 4, and the movement of the tether ring 25 causes the combing post 24 to move away from the copper wire harness under the action of the first spring bearing 26, and the two elastic telescopic rods 27 contract, causing the two arc-shaped pressing plates 28 to gradually move away from each other until the combing post 24 moves completely from the end close to the mounting plate 4 to the end remote from the mounting plate 4, and the first electric telescopic rod 31 contracts, causing the locking block 22 to leave the insertion groove at the end close to the mounting plate 4 on the second slide rail 14, and then the feeding and fixing mechanism controls the wire harness to be inserted into the terminal and crimped.

[0028] The feed and fixation mechanism includes: A first slide rail 3 is attached to the frame 1, is horizontal, and is located above the mounting plate 4; and an electric clamp 5 slidably mounted within the first slide rail 3 via an electric slider.

[0029] In this embodiment, the electric slider drives the electric clamp 5 to clamp the wire harness and slide within the first slide rail 3, and the electric clamp 5 controls the wire harness to complete the crimping process, the bending straightening process and the combing process, eliminating the need to manually hold and crimp the wire harness.

[0030] The terminal control mechanism further includes: A supply pipe 37 is attached to the frame 1 and has circular through holes on both sides. A second electric telescopic rod 39 is attached to the frame 1, is horizontal, and has a circular push plate at its telescopic end, and the circular push plate on the second electric telescopic rod 39 is slidably fitted into the circular through hole of the supply pipe 37; a first rotating cylinder 32 attached to the supply pipe 37 on a side away from the second electric telescopic rod 39, having four arc-shaped through holes bored thereon, the four arc-shaped through holes being equally spaced apart in an annular shape; The terminal is clamped and fixed, preventing the terminal from shaking when the copper wire harness is inserted into the terminal, and a holding and rotating assembly is provided which controls the reciprocating rotation of the clamped terminal.

[0031] The holding and rotating assembly includes: An adjustment wheel 36 is attached to the frame 1, and four arc-shaped blocks are arranged in a ring at equal intervals therein, and each of the arc-shaped blocks has a gradually decreasing diameter along the inner diameter direction of the adjustment wheel 36; a second rotating cylinder 33 rotatably provided on the outer ring surface of the first rotating cylinder 32 and having four equally spaced through holes formed thereon; Four second spring bearings 34 are provided, and are arranged annularly at equal intervals on the outer ring surface of the second rotating cylinder 33, and the axis of the second spring bearing 34 overlaps with the axis of the through hole on the second rotating cylinder 33; Four pressing posts 35 are provided, arranged at equal intervals in a ring shape, and each pressing post 35 is connected to one of the second spring supports 34 so that power can be transmitted thereto. The end of the pressing post 35 away from the second rotating cylinder 33 is circular, and the end close to the second rotating cylinder 33 is a flexible surface having elasticity.

[0032] A second ring gear 38 attached to an outer ring surface of the second rotary cylinder 33; A second motor 40 mounted on the frame 1; The second motor 40 further includes a second spur gear 41 that is fixedly connected to an output shaft of the second motor 40 and meshes with the second ring gear 38 .

[0033] In this embodiment, the terminal enters from the supply pipe 37, the second electric telescopic rod 39 pushes the terminal into the first rotating barrel 32, the second motor 40 rotates the second spur gear 41, the second spur gear 41 rotates the second ring gear 38, the rotation of the second ring gear 38 rotates the second rotating barrel 33, and the rotation of the second rotating barrel 33 causes the four pressing posts 35 to approach the center of the adjusting wheel 36 while being regulated by the four arc-shaped blocks of the adjusting wheel 36, and to clamp the terminal. When the terminal is at the center position of the first rotating barrel 32, the pressing posts 35 press the second spring After the spring on the receiver 34 is compressed and the terminal is clamped, the copper wire harness is gradually inserted into the terminal under the control of the electric clamp 5. When the copper wire harness is inserted into the terminal, the second motor 40 periodically rotates forward and backward, and the second rotating cylinder 33 rotates slightly back and forth. At this time, the end of the pressing post 35 that is joined to the terminal is an elastic and flexible surface, so that the second rotating cylinder 33 rotates slightly, and the pressing post 35 clamps the terminal and rotates slightly, so that the copper wire harness can be easily inserted into the terminal, and the next crimping process can proceed smoothly. After crimping is completed, the second motor 40 is rotated in the reverse direction and reset, causing the second rotating cylinder 33 to rotate. As the second rotating cylinder 33 rotates, the spring in the second spring receiver 34 expands, causing the pressing post 35 to gradually move away from the terminal. Thereafter, the electric clamp 5 controls the crimped wire harness to move away from under the crimping blade 2, facilitating the subsequent crimping of the wire harness and the terminal.

[0034] The above is merely a preferred embodiment of the present invention, and is not intended to limit the present invention.
