Description

Technical Field

[0001] The invention relates to the technical field of wire harness crimping equipment, in particular to an automatic wire harness crimping equipment. Background Art

[0002] Wire harness terminal crimping refers to the process of tightly connecting the conductor part of the wire and the terminal through mechanical pressure. It is a very important step in electrical connection. During the crimping process, wire strippers are generally used to strip the insulation layer at the end of the wire to expose the conductor part, and then the stripped wire conductor part is inserted into the conductor clamping part of the terminal to ensure that the conductor is fully inserted into place. After that, the terminal with the inserted wire is placed in the corresponding mold of the crimping pliers, and the handle of the crimping pliers is pressed to apply enough pressure to tightly connect the terminal with the wire conductor. During the automatic crimping process of the wire harness, the crimping end of the wire harness is manually stripped to remove the insulation layer, and then the wire harness is manually plugged into the terminal block one by one, which has low plugging efficiency. The wire harness is then transferred to the crimping equipment for crimping, which has low production efficiency. After the crimping end of the wire harness is stripped, the metal wires of the wire core in the wire harness will spread radially due to the lack of the constraint of the insulation skin. Direct plugging will make the crimped product unqualified. Therefore, when the wire harness is plugged into the wire harness terminal, the scattered metal wires need to be manually twisted together, which is more troublesome and affects the crimping efficiency of the wire harness. Summary of the invention

[0020] The following will clearly and completely describe a wire harness automatic crimping device in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without making creative efforts belong to the protection scope of the present invention Embodiment

[0021] As Figure 1 and Figure 2 shown, a wire harness automatic crimping device includes an operating table 10 and a driving component 11 installed on the upper side of the operating table 10. The driving component 11 includes a disc and a driving motor. The driving motor is installed on the operating table 10, and the circular plate is located on the upper side of the operating table 10. The disc can be rotated by the driving motor Next, a hexagonal crimping device 12, a manipulator 13, and a coaxial stripper 14 are installed on the driving component 11. The hexagonal crimping device 12 is used for hexagonal crimping of the wire harness and the terminal. The hexagonal crimping makes the core filling effect better. The manipulator 13 is a prior art and is used for feeding the terminal, placing the terminal under the crimping die of the hexagonal crimping device 12, and at the same time, the crimped wire harness can be drawn out for discharging. The coaxial stripper 14 is used for stripping the insulation layer of the wire harness. A plurality of annularly arrayed conveying components 20 are fixed on the upper side of the operating table 10, and the conveying components 20 are used for feeding the wire harness By arranging a plurality of conveying components 20, the device can continuously feed the wire harness. At the same time, the rotating coaxial stripper 14 processes the wire harness conveyed by the plurality of conveying components 20, and then the manipulator 13 conveys the terminal to the die of the hexagonal crimping device 12 for crimping. There is no need for manual wire harness stripping and plugging, which improves the crimping efficiency of the device. This device is applicable to large-square wire harnesses. The large-square wire harnesses will not be bent too much during feeding, which is convenient for conveying

[0022] Furthermore, as Figure 3 and Figure 4As shown, the conveying component 20 includes a fixing plate 21 fixed to the operating table 10. A guide rail 22 is fixed on the fixing plate 21. A clamping component 40 is fixedly installed at the output end of the guide rail 22. The guide rail 22 controls the overall movement of the clamping component 40, so that the wire harness clamped by the clamping component 40 can move. A feeding component 30 adapted to the clamping component 40 is fixed on one side of the fixing plate 21. The feeding component 30 is used to convey the wire harness into the clamping component 40, eliminating the need for manual feeding. Next, a wire core concentrating component 50 adapted to the clamping component 40 is fixed on one side of the guide rail 22. The wire core concentrating component 50 is used to organize the stripped wire harness. A transmission component 60 is rotatably installed on one side of the feeding component 30. The transmission component 60 is used to drive the wire core concentrating component 50 when the clamping component 40 moves, causing the components in the wire core concentrating component 50 to rotate.

[0023] Furthermore, as Figure 5 and Figure 6 shown, the feeding component 30 includes a mounting tube 31 fixed to the operating table 10 through a mounting block. The mounting block is fixed on the operating table 10, and the mounting tube 31 is fixed on the mounting block. A feeding port 35 is installed on the outer surface of the mounting tube 31. The feeding port 35 is used for feeding the wire harness. A first motor 34 is fixed on one side of the mounting tube 31. A rotating column 36 that rotates in the inner cavity of the mounting tube 31 is fixed to the output end of the first motor 34. A plurality of feeding grooves 37 adapted to the feeding port 35 are formed on the outer surface of the rotating column 36. The wire harness fed through the feeding port 35 will fall into the inner cavity of the feeding groove 37. Moreover, there are spiral protrusions on the inner cavity side wall of the mounting tube 31, so that when the rotating column 36 rotates, the wire harness in the inner cavity of the feeding groove 37 can be flattened during the extrusion by the protrusions, making the wire harness tend to be straight and facilitating conveying. Feeding holes and pushing holes corresponding to the feeding grooves 37 are respectively formed on both sides of the mounting tube 31. The feeding hole on one side of the feeding groove 37 is for use corresponding to the clamping component 40. Next, a first cylinder 32 is fixed on the outer surface of the mounting tube 31. A push rod 33 adapted to the feeding groove 37 is fixed to the output end of the first cylinder 32. The push rod 33 can extend into the pushing hole on the mounting tube 31 to push the wire harness in the inner cavity of the feeding groove 37 towards the clamping component 40.

[0024] Furthermore, as Figure 7 and Figure 8 shown, the clamping component 40 includes a connection block 41 fixedly connected to the output end of the guide rail 22. A fixed tube 44 is fixed on one side of the connection block 41. One end of the fixed tube 44 is fully open, and only a hole for the wire harness to pass through is formed at the other end. A rotating component 43 is rotatably installed on the inner surface of the fixed tube 44. A second cylinder 42 adapted to the rotating component 43 is fixed on one side of the connection block 41 through a mounting block. The mounting block is fixedly connected to the connection block 41, and the second cylinder 42 is installed on the mounting block. A connecting rod 45 is fixed on the outer surface of the fixed tube 44. ​Among them, several annularly arrayed extrusion components 47 are slidably installed on one side of the rotating component 43. The several annularly arrayed extrusion components 47 can contract or expand. When contracting, they can clamp the wire harness. A plurality of limiting grooves 46 adapted to the extrusion components 47 are provided on one side of the fixing tube 44. The limiting grooves 46 are used to limit the moving direction and position of the extrusion components 47; Further, as Figure 9 and Figure 10 shown, the rotating component 43 includes a rotating ring 431 movably installed on the inner surface of the fixing tube 44. The rotating ring 431 rotates on the inner surface of the fixing tube 44. A pushing groove 432 adapted to the extrusion component 47 is provided on one side of the rotating ring 431. The pushing groove 432 is hexagonal, and each side corresponds to an extrusion component 47, which is used to control the moving position of the extrusion component 47; Next, a groove block 433 passing through the fixing tube 44 and adapted to the second cylinder 42 is fixed on the outer surface of the rotating ring 431. A through groove for the movement of the groove block 433 is provided on the outer surface of the fixing tube 44. The positioning column fixed on the output end of the second cylinder 42 slides in the inner cavity of the groove of the groove block 433. The rotation of the rotating ring 431 can be controlled by the second cylinder 42 and the groove block 433, so as to control the contraction and expansion of the plurality of extrusion components 47 through the pushing groove 432; Further, as Figures 9 - 11 shown, the extrusion component 47 includes a slider 472 slidably installed in the inner cavity of the groove block 433. An extrusion block 471 is fixed on one side of the slider 472. The plurality of extrusion blocks 471 are in close contact with each other and are annularly arrayed. A fixing column 475 adapted to the limiting groove 46 is fixed on one side of the extrusion block 471. The fixing column 475 slides in the inner cavity of the corresponding limiting groove 46. Through the cooperation between the rotating component 43 and the slider 472, and the limitation between the fixing column 475 and the limiting groove 46, the plurality of extrusion blocks 471 can expand or contract for clamping the wire harness; Next, a group of extrusion strips 473 are fixed on one inclined surface of the extrusion block 471. There are a plurality of the group of extrusion strips 473, and the diameter of one end of the extrusion strip 473 close to the center of the fixing tube 44 is larger than that of the other end. An extrusion groove 474 adapted to the extrusion strip 473 is provided on the other inclined surface of the extrusion block 471. Since the extrusion blocks 471 are in close contact with each other, the provided extrusion groove 474 can hide the adjacent extrusion strips 473 and will not affect the movement between the plurality of extrusion blocks 471. When the plurality of extrusion blocks 471 contract, the wire harness can be slightly reversely twisted by the extrusion strips 473 passing through and pushing the wire harness;

[0025] Further, as Figure 12As shown, the transmission component 60 includes a round rod 61 rotatably mounted on one side of the mounting tube 31. A spiral groove 62 and a straight groove 63 communicating with the spiral groove 62 are formed on the outer surface of the round rod 61. The spiral groove 62 and the straight groove 63 are adapted to the connecting rod 45. The connecting rod 45 can slide in the inner cavities of the spiral groove 62 and the straight groove 63, so as to rotate the round rod 61. A spur gear ring 64 is fixedly mounted on the outer surface of the round rod 61 through a one-way bearing; Among them, as Figure 13 and Figure 15 shown, during the process of the connecting rod 45 moving towards the wire core concentrating component 50, due to the one-way bearing connected to the round rod 61, the spur gear ring 64 rotates idly. During the process of the connecting rod 45 moving back to the side away from the wire core concentrating component 50, due to the effect of the one-way bearing, the spur gear ring 64 can be rotated, but within the range of the straight groove 63, the round rod 61 does not rotate, and within the range of the spiral groove 62, the round rod 61 can be rotated.

[0026] Furthermore, as Figure 14 and Figure 15 shown, the wire core concentrating component 50 includes a connecting plate 51. The connecting plate 51 is fixedly connected to one side of the guide rail 22 through a mounting bracket. A movable component 52 is rotatably mounted on one side of the connecting plate 51. A matching component 53 is rotatably mounted on one side of the movable component 52. A plurality of twisting components 54 in an annular array are fixed on one side of the movable component 52. The plurality of twisting components 54 are annular. The movable component 52 and the matching component 53 cooperate to enable the plurality of twisting components 54 to contract or expand, facilitating the passing of the wire harness; Furthermore, as Figures 16 - 18 shown, the movable component 52 includes a movable ring 521 penetrating and rotatably mounted on the connecting plate 51. A plurality of annularly arrayed sliding grooves 522 are formed on the movable ring 521. The number of the sliding grooves 522 is the same as that of the twisting components 54. Connecting rods 523 are slidably connected to the inner cavities of the plurality of sliding grooves 522. A positioning component 526 is fixed on one of the connecting rods 523; Among them, the positioning component 526 is used to detect the position of wire harness cutting. The positioning component 526 does not include a positioner and a cleaning block. When the positioner detects the wire harness cutting position, the cleaning block contacts the insulating layer at the notch. When the movable component 52 rotates, the debris at the cutting position can be cleaned, preventing short circuit between the wire core and the terminal after crimping; Next, a second motor 524 is fixedly mounted on the outer surface of the movable ring 521 through a mounting block. The mounting block is fixed on the movable ring 521 and can move with the movable ring 521. The second motor 524 is fixedly connected between the mounting rod and the mounting block. A gear 525 is fixed to the output end of the second motor 524. A first half gear ring 527 meshing with the spur gear ring 64 is fixed on the outer surface of the movable ring 521. When the spur gear ring 64 rotates, it can drive the first half gear ring 527 to rotate, so as to rotate the whole movable component 52, but the rotation angle of the movable component 52 is relatively small; Furthermore, as shown in Figure 16 — Figure 18 shown, the cooperating component 53 includes a cooperating ring 531 rotatably connected to the movable ring 521. A plurality of arc-shaped grooves 532 adapted to the connecting rods 523 are formed in the cooperating ring 531. The connecting rods 523 are also located in the inner cavities of the corresponding arc-shaped grooves 532. By rotating the cooperating ring 531, the connecting rods 523 located in the inner cavities of the arc-shaped grooves 532 move up and down, thereby controlling the expansion and contraction of the plurality of connecting rods 523. A semi-tooth ring two 533 adapted to the gear 525 is fixed on the outer surface of the cooperating ring 531. The motor two 524 controls the rotation of the gear 525 and the semi-tooth ring two 533, thereby controlling the rotation of the cooperating ring 531 and controlling the expansion or contraction between the plurality of connecting rods 523; Furthermore, as shown in Figure 16 — Figure 18 shown, the wire-twisting component 54 includes an arc-shaped block 541 fixedly connected to the connecting rod 523. A plurality of telescopic rods 542 move with the expansion or contraction of the connecting rod 523, facilitating the passing of the wire harness. A plurality of telescopically distributed telescopic rods 542 are fixedly installed through the arc-shaped block 541. The telescopic rods 542 have a certain telescopic ability. The output ends of the plurality of telescopic rods 542 are commonly fixed with a spiral twisting strip 543. The twisting strip 543 will contact the wire harness and at the same time contact the exposed metal wire core after peeling during the process of the wire harness moving away from the hexagonal crimping device 12. As the wire harness moves, the scattered wire cores can be concentrated. At the same time, due to the rotation of the plurality of twisting strips 543, the wire cores can be twisted forward. In cooperation with the clamping component 40, the wire cores are concentrated and gathered together without manual twisting, facilitating the insertion into the terminal; Among them, a positioning block 544 is fixed on one side of the arc-shaped block 541 through a mounting rod. The plurality of positioning blocks 544 form a tapered tube. The tapered tube formed by the plurality of positioning blocks 544 facilitates the fixing of the wire harness, facilitates the peeling operation of the coaxial peeler 14, and at the same time can contract the metal wires that are too scattered after peeling, facilitating the concentration; Through the action of the cylinder two 42 and the rotating component 43, the plurality of contracted extrusion components 47 apply reverse twisting during the process of clamping the wire harness. At the same time, during the process of the wire harness moving away from the wire core concentrating component 50 after peeling, due to the action of the transmission component 60, the wire harness is positively twisted by the rotating wire-twisting component 54 on the core wire during the moving process, so that the scattered metal silk threads in the core wire are gathered and concentrated.

[0027] It should be noted that the driving component 11, the hexagonal crimping device 12, the manipulator 13, the coaxial peeler 14, the guide rail 22, the cylinder one 32, the motor one 34, etc. in the present invention are all prior arts, and their installation methods and control methods also belong to conventional designs, and the present invention will not be elaborated in detail.

[0028] Working principle of the present invention: The device can automatically strip the crimping end of the wire harness and remove the insulation layer through the cooperation between the set driving component 11, the hexagonal crimping device 12, the manipulator 13, the coaxial stripper 14 and the multiple conveying components 20, and then the wire harness and the wiring terminal are plugged one by one through the cooperation between the components in the conveying component 20 and the manipulator 13 to improve the plug-in efficiency, and then the wire harness and the wiring terminal are crimped again by the manipulator 13 to improve the production efficiency; The feeding component 30 can automatically feed and transport the wire harness, avoiding manual feeding, improving the feeding efficiency of the wire harness, and thus improving the production efficiency of the device; Place the wire harness in the loading port 35, and rotate the rotating column 36 with the motor 1 34, so that the wire harness falls into the inner cavity of the loading groove 37 on the surface of the rotating column 36. As the rotating column 36 rotates, the loading groove 37 corresponds to the loading holes and the pushing holes on both sides of the mounting tube 31, and then the wire harness in the inner cavity of the loading groove 37 is pushed toward the side of the clamping component 40 under the action of the push rod 33 connected to the output end of the cylinder 1 32; Since a plurality of feeding grooves 37 are provided on the surface of the rotating column 36, the wire harness in the feeding port 35 can still fall into the inner cavity of another feeding groove 37 after the rotating column 36 rotates, and then wait for operation without manual transportation; Through the cooperation between the clamping component 40, the wire core concentration component 50 and the transmission component 60, not only can the wire harness be guided to cooperate with the coaxial stripper 14 for automatic stripping, but also the metal wires exposed on the wire harness after stripping can be gathered and twisted to concentrate the wire cores for easy plugging with the wiring terminals without manual twisting, thereby improving the plugging efficiency of the device and further improving the production efficiency of the device; The wire harness pushed out through the feeding trough 37 enters the middle of the multiple extrusion assemblies 47. Under the action of the second cylinder 42 and the slot block 433, the rotating ring 431 rotates in the inner cavity of the fixed tube 44. At the same time, the slider 472 slides in the inner cavity of the pushing slot 432, and cooperates with the limiting slot 46 on the fixed tube 44 to limit the fixed column 475, so that the multiple extrusion blocks 471 contract to clamp the wire harness. In the process of the extrusion block 471 contracting, the extrusion strip 473 on the extrusion block 471 contacts the surface of the wire harness, which can push the wire harness to rotate slightly, so that the wire harness is reversely twisted. Then, the wire harness clamped by the multiple extrusion components 47 moves to one side of the wire core concentration component 50 under the action of the guide rail 22, passes through the inside of the wire core concentration component 50, and under the action of the movable component 52 and the matching component 53, the multiple twisting components 54 expand to allow the wire harness to pass through, and then the wire harness docks with the coaxial stripper 14 to strip one end of the wire harness; Then, the guide rail 22 moves, so that the wire harness clamped by the multiple extrusion assemblies 47 moves to the side away from the wire core concentration component 50. At this time, the motor 2 524 drives the gear 525 to rotate, so that the gear 525 drives the meshing half gear ring 2 533 to rotate with the matching ring 531. Through the cooperation between the arc groove 532 and the slide groove 522, the connecting rod 523 located in the inner cavity of the arc groove 532 and the movable ring 521 slides, thereby controlling the contraction between the multiple connected twisting assemblies 54. A plurality of positioning blocks 544 form a tapered tube to gather the divergent metal wires after peeling toward the center, and then, because the torsion bar 543 contacts the surface of the wire core of the wire harness, the bent and warped metal wires can be further gathered toward the center of the wire core during the process of the wire harness moving away from the wire core concentration component 50; At the same time, since the connecting rod 45 slides in the inner cavity of the spiral groove 62 and the straight groove 63, the round rod 61 rotates with the spur gear ring 64, so that the spur gear ring 64 drives the movable ring 521 to rotate with the meshing half gear ring 527, so that the multiple twisting components 54 rotate, so that the multiple spiral twisting bars 543 rotate on the surface of the wire core, and the wire core is twisted in the positive direction. By cooperating with the multiple extrusion components 47 to twist the wire harness in the reverse direction, the wires can be twisted together, so that the metal wires of the wire core are gathered and concentrated; Then, the multiple wire twisting components 54 expand again under the action of the movable component 52 and the matching component 53. As the guide rail 22 moves with the clamping component 40, the wire harness clamped by the multiple extrusion components 47 is sent to the side of the hexagonal crimping device 12, the twisted wire cores are plugged into the terminal blocks, and then the wire harness and the terminal blocks are crimped. After that, the crimped wire harness is taken away by the manipulator 13, and the driving component 11 is rotated to make the hexagonal crimping device 12 crimp the wire harness conveyed by the next conveying component 20, thereby improving the production efficiency of the device.
