Description

Technical Field

[0001] This invention relates to the field of cable harness assembly manufacturing technology, specifically to a cable harness assembly manufacturing apparatus and manufacturing process. Background Technology

[0002] In the production process of cable harness assemblies, the crimping of conductors and terminals is a core process, involving several key steps such as conductor feeding, stripping and twisting of the crimping ends, and terminal positioning and crimping. This directly affects the connection reliability and production efficiency of the cable harness assembly. In existing technologies, cable harness assembly production equipment often adopts a decentralized structural design. Processes such as conductor feeding, stripping, and terminal crimping often require multiple independent machines or manual intervention for process coordination and material transfer, resulting in a discontinuous production flow and low production efficiency.

[0003] In the wire conveying stage, existing conveying equipment lacks sufficient precision in the synchronous positioning and conveying of multiple wires. Displacement and offset of multiple wires are prone to occur during conveying, making it difficult to accurately match the crimping position of the terminals, thus affecting the subsequent crimping quality. Furthermore, the conveying mechanism has poor adaptability to different wire specifications; changing wire specifications requires readjustment of the tooling, which is cumbersome. Regarding stripping and twisting, existing technologies often separate these two processes. After stripping, twisting requires manual labor or additional equipment, which not only increases the complexity of the process but also easily leads to exposed copper wires, causing short circuit hazards during crimping. Moreover, the consistency of stripping dimensions is difficult to guarantee. Summary of the Invention

[0004] In order to overcome the shortcomings of the prior art, the present invention provides a cable harness assembly production device and production process, which realizes continuous production from wire pretreatment to terminal crimping, without the need for manual intervention for process switching and material transfer, significantly improving the continuity of the production process, greatly reducing the time spent on process connection, and thus improving the overall production efficiency.

An adjusting servo cylinder is slidably provided on one side of the lifting linear slide. A connecting block is fixedly provided at the drive end of the adjusting servo cylinder. A flipping frame is rotatably provided between the two connecting blocks. A flipping servo motor is fixedly provided inside the connecting block. The output shaft of the flipping servo motor is fixedly connected to the flipping frame. Several processing frames are fixedly provided on one side of the flipping frame.

[0012] Furthermore, a rotating frame 2 is rotatably provided on both sides inside the processing frame. The rotating frame 2 is driven by a micro geared motor built into the processing frame.

[0017] 3. The processes of wire feeding, stripping and twisting, terminal crimping, wire harness winding and bundling, and waste discharge are all automated through the coordinated drive of servo electric cylinders, linear slides, and micro motors, reducing the impact of manual operation on production efficiency and product quality. The wire sheaths generated during stripping are automatically discharged through the flipping frame and discharge channel, eliminating the need for manual cleaning and further ensuring production continuity. The terminal crimping adopts a bidirectional coordinated pressure design to ensure uniform crimping pressure distribution, enabling the terminal and wire to form a firm mechanical engagement and stable electrical connection, significantly reducing quality risks such as loose connections and disconnections, and improving the connection reliability and service life of the wire harness assembly.

[0018] 4. All functional components are integrated onto the production frame, with a scientific layout, small footprint, and convenient workshop layout and equipment maintenance.

[0020] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0021] In the description of this invention, it should be understood that the terms "upper", "lower", "front", "rear", "left", "right", "top", "bottom", "inner", "outer", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this invention.

[0022] Example 1 Please see Figures 1 to 8 As shown, a cable harness assembly production device includes a production frame 1. Feeding mounting frames 2 are fixedly installed on both sides of the top of the production frame 1, and a pressing mounting frame 3 is fixedly installed in the middle of the top of the production frame 1. A terminal crimping assembly 4 is provided between the bottom of the pressing mounting frame 3 and the top of the production frame 1, and the cable conductors and terminals are crimped together by the terminal crimping assembly 4. A wire conveying assembly 5 is provided on one side of each of the two feeding mounting frames 2, and multiple cable conductors are automatically conveyed by the wire conveying assembly 5. A crimping processing assembly 6 is also provided on the opposite side of the two feeding mounting frames 2, and the crimping processing assembly 6 strips the insulation from the crimped ends of the cable conductors.

[0023] It should be noted that the feeding mounting frames 2 on both sides of the top of the production frame 1 automatically feed the cable conductors with the appropriate number of terminals. The crimping processing components 6 on one side of the two feeding mounting frames 2 perform quantitative stripping of one end of the cable conductors, and then twist the stripped multi-strand copper wires to prevent short circuits caused by exposed loose wires during crimping. Finally, the processed cable conductor crimped end is fed into the terminal, where the terminal crimping component 4 performs the crimping process between the terminal and the cable conductor. The wire feeding components 5 and crimping processing components 6 on both sides enable continuous crimping processing between the cable conductors and terminals. While the left-side wire feeding component 5 and crimping processing component 6 are crimping the processed cable conductors and terminals, the right-side component 5 and crimping processing component 6 are used to strip and twist the crimped end of the cable conductors. This also allows for simultaneous crimping of the cable conductors at both ends of the assembly terminals, enabling the production of cable harness assemblies of different configurations.

[0024] Specifically, the terminal crimping assembly 4 includes a terminal mounting bracket 9. Two upper crimping servo cylinders 7 are fixedly installed on the top of the crimping fixing bracket 3, and two lower crimping servo cylinders 8 are also fixedly installed in the middle of the production frame 1. The terminal mounting brackets 9 are fixedly installed on the drive ends of the two upper crimping servo cylinders 7 and the two lower crimping servo cylinders 8 respectively. The upper and lower half of the terminal are installed by the two terminal mounting brackets 9 respectively. The lower terminal mounting bracket 9 is raised to the same level as the cable conductor by the drive end of the lower crimping servo cylinder 8. After the processed cable conductor is sent into the metal sheath in the lower half of the terminal, the upper and lower half of the terminal are crimped by the drive end of the upper crimping servo cylinder 7.

[0025] Example 2 Specifically, this embodiment is a detailed description of the structure of the wire conveying assembly 5 in the above embodiment 1. The wire conveying assembly 5 includes a conveying frame 11 and a winding frame 17. Two conveying servo cylinders 10 are fixedly installed on one side of the feeding mounting frame 2, and the conveying frame 11 is fixedly installed on the drive end of the two conveying servo cylinders 10. Several wire grooves 12 are provided inside the conveying frame 11. First micro cylinders 13 are fixedly installed around the inside of the several wire grooves 12, and connecting frames 14 are fixedly installed on the drive end of the four first micro cylinders 13. Conveyor belts 15 are rotatably installed inside the four connecting frames 14, and one side of the conveyor belts 15 extends to the outside of the connecting frames 14.

[0026] It should be noted that when conveying multiple sets of cable conductors, the cable conductors are arranged inside several conductor grooves 12 according to the crimping position of the terminals. The drive end of the first micro electric cylinder 13 controls the connecting frame 14 to approach the surface of the cable conductors until the conveyor belt 15 on the outside of the connecting frame 14 contacts the surface of the cable conductors. By controlling the synchronous rotation of the conveyor belt 15 on the outside of the connecting frame 14, the cable conductors are conveyed to one side of the feeding mounting frame 2 inside the conductor grooves 12. By controlling the rotation speed of the conveyor belt 15, stable control of the cable conductors is achieved.

[0027] Furthermore, a rotating frame 16 is rotatably arranged inside the feeding mounting frame 2, and a winding frame 17 is fixedly arranged inside the rotating frame 16; a winding servo motor 18 is fixedly arranged on one side of the feeding mounting frame 2, and a drive gear 19 is fixedly arranged at one end of the output shaft of the winding servo motor 18; an annular tooth groove is provided on the outer circumferential surface of the rotating frame 16, and the tooth surface of the drive gear 19 meshes with the tooth surface of the annular tooth groove for transmission.

[0028] Furthermore, the winding frame 17 has several wire grooves 20 inside, and micro linear slides 21 are fixedly installed on both sides of the wire grooves 20. Two clamping micro electric cylinders 22 are slidably installed on one side of each of the two micro linear slides 21, and clamping blocks 23 are fixedly installed at the driving ends of the clamping micro electric cylinders 22 on both sides. Clamping micro electric cylinders 24 are fixedly installed above and below the two clamping blocks 23, and clamping plates 25 are fixedly installed at the driving ends of the two clamping micro electric cylinders 24.

[0029] It should be noted that a rubber pad is provided on one side of the clamping plate 25. After the cable conductor is conveyed to a certain length, in order to facilitate the subsequent stripping and twisting of the cable conductor crimped end, one end of the cable conductor is fed into the interior of several conductor grooves 20. The driving end of the clamping micro electric cylinder 22 controls the clamping block 23 to move closer to the surface of the cable conductor. Simultaneously, the driving ends of two clamping micro electric cylinders 24 on one side of the clamping block 23 control the clamping plate 25 to move closer to the surface of the cable conductor, thus clamping the cable surface with the clamping plate 25 to maintain its position. To ensure the stability of subsequent processing of the crimped ends and stripped twisted ends of the cable conductors; after crimping multiple sets of cable conductors and terminals, the output shaft of the winding servo motor 18 controls the drive gear 19 to rotate. The drive gear 19 and the annular tooth groove on the outer circumference of the rotating frame 16 mesh to drive the rotating frame 16 to rotate inside the feeding mounting frame 2, thereby driving the winding frame 17 to rotate at a certain angle, and winding multiple sets of cable conductors on the outside of the terminal to perform winding processing, and binding processing with cable ties to prevent the multiple sets of cable conductors on the outside of the terminal from becoming scattered.

[0030] Example 3 Specifically, this embodiment is a detailed description of the structure of the crimping processing component 6 in the above embodiment 1. The crimping processing component 6 includes a flipping frame 30 and a processing frame 31. Two lifting linear slides 26 are fixedly arranged on one side of the feeding mounting frame 2, and an adjusting servo cylinder 27 is slidably arranged on one side of each of the two lifting linear slides 26. A connecting block 28 is fixedly arranged on the drive end of each of the two adjusting servo cylinders 27, and a flipping frame 30 is rotatably arranged between the two connecting blocks 28. A flipping servo motor 29 is fixedly arranged inside each of the two connecting blocks 28, and one end of the output shaft of each of the two flipping servo motors 29 is fixedly connected to both sides of the flipping frame 30. Several processing frames 31 are fixedly arranged on one side of the flipping frame 30.

[0031] Furthermore, rotating frames 32 are rotatably installed on both sides inside several processing frames 31, and one side of each rotating frame 32 is driven to rotate by a micro geared motor built into the processing frame 31. Several circumferential cutting servo cylinders 35 are fixedly installed inside each of the two rotating frames 32. The driving ends of several circumferential cutting servo cylinders 35 near the feeding mounting frame 2 are fixedly equipped with circumferential cutting tools, and the driving ends of several circumferential cutting servo cylinders 35 near the flipping frame 30 are fixedly equipped with rubber pressure blocks.

[0032] Furthermore, several cutting linear slides 33 are fixedly installed inside each of the processing racks 31, and the several cutting linear slides 33 are arranged in a circumferential manner at equal angles inside the processing racks 31. A straight cutting servo cylinder 34 is slidably installed on one side of each of the several cutting linear slides 33, and a peeling knife is fixedly installed on the drive end of each of the several straight cutting servo cylinders 34.

[0033] Furthermore, several material discharge ports 36 are provided on both sides of the top of the production frame 1, and discharge channels 37 are provided on both sides inside the production frame 1, with the top of the discharge channels 37 on both sides respectively connected to the interior of several material discharge ports 36 on both sides.

[0034] It should be noted that during the stripping and twisting of the crimped end of the cable conductor, the lifting linear slide 26 drives the adjusting servo cylinder 27 to a position level with the winding frame 17. Then, the drive end of the adjusting servo cylinder 27 controls the flipping frame 30 to move closer to one side of the winding frame 17, allowing several processing frames 31 to enter the interior of several conductor grooves 20. At this time, the crimped end of the cable conductor enters the interior of several processing frames 31. After clamping and positioning one end of the cable conductor by the clamping plate 25, the drive end of the circumferential cutting servo cylinder 35 inserts the circumferential cutting tool into the interior of the cable conductor, and the rotating frame 32 performs circumferential cutting on one end of the cable conductor. At the same time, several straight cutting servo cylinders 34 insert the stripping tool into the interior of the cable conductor, and the cutting linear slide 33 performs the cutting. One end of the cable conductor is stripped, leaving a certain amount of slack at the cable conductor end. The end of the cable conductor is clamped and limited by the ring-cutting servo cylinder 35 and rubber pressure block near the flipping frame 30. The copper wire in the stripped area of ​​the cable conductor is twisted in conjunction with the rotating frame 32. After the twisting of the cable conductor is completed, the stripping blade is used to strip the end of the cable conductor. The stripped conductor sheath remains inside the processing frame 31. The flipping frame 30 is removed from the inside of the conductor trough 20. The lifting linear slide 26 controls the flipping frame 30 to move downward. The output shaft of the flipping servo motor 29 controls the flipping frame 30 to rotate 90 degrees, dropping the conductor sheaths inside several processing frames 31 into several material discharge ports 36. Finally, the conductor sheaths are sent out through the discharge channel 37.

[0035] Example 4 Please see Figure 9 As shown, specifically, this embodiment proposes a cable harness assembly production process applied to a cable harness assembly production device in the above embodiments, including the following steps: Step 1: Reset the upper crimping servo cylinder 7 and the lower crimping servo cylinder 8 to their initial positions, ensuring that the terminal mounting bracket 9 is in the open state; calibrate the zero point of the travel of the conveying servo cylinder 10, the lifting linear slide 26, and the servo cylinder 27 to ensure the precise movement of each motion mechanism; divide the terminals to be crimped into upper and lower halves, and install them into the upper and lower terminal mounting brackets 9 respectively; according to the number and spacing of the crimped terminals, place multiple cable wires into several wire slots 12 of the conveying frame 11, ensuring that the extension direction of each wire is consistent and the crimping end faces the crimping fixing bracket 3; control the miniature linear slide 21 in the wire slot 20 to drive the clamping miniature electric cylinder 22 to move, so that the clamping block 23 is aligned with the wire conveying path; drive the clamping block 23 to approach the wire through the clamping miniature electric cylinder 22, and then drive the clamping plate 25 to lightly touch the surface of the wire through the clamping miniature electric cylinder 24 to complete the wire pre-positioning.

[0036] Step 2: Control the drive ends of the two conveying servo cylinders 10 to extend, driving the conveyor frame 11 to move inward to the preset conveying position within the feeding mounting frame 2; activate the four first micro-cylinders 13 in the first wire groove 12 to drive the connecting frame 14 to approach the wire surface until the conveyor belt 15 is in close contact with the wire surface; control the conveyor belts 15 on the outer side of all connecting frames 14 to rotate synchronously at the same speed, driving the wire to be conveyed towards the winding frame 17 within the first wire groove 12; preset the rotation time and speed of the conveyor belt 15 according to production requirements to ensure that the length of the wire conveyed into the second wire groove 20 meets the crimping end processing requirements, i.e., the length of the crimping end extending out of the clamping plate 25 is the stripping allowance; when the wire is conveyed to the preset length, the conveyor belt 15 stops rotating, and the first micro-cylinder 13 drives the connecting frame 14 to slightly retract to maintain the wire's stable posture; at the same time, the clamping micro-cylinder 24 drives the clamping plate 25 to clamp the wire surface, increasing friction through the rubber pad to prevent wire displacement during subsequent processing.

[0037] Step 3: Activate the lifting linear slide 26 to drive the adjusting servo cylinder 27 and the tilting frame 30 to rise and fall, so that the height of several processing frames 31 is consistent with that of the wire groove 20; control the drive end of the adjusting servo cylinder 27 to extend, pushing the tilting frame 30 closer to the winding frame 17 until the processing frame 31 is inserted into the wire groove 20 and the crimping end of the wire extends into the processing frame 31; activate the circumferential cutting servo cylinder 35 on the side of the processing frame 31 near the feeding mounting frame 2, driving the circumferential cutting tool to extend into the outside of the wire insulation layer, while the built-in micro geared motor drives the rotating frame 2 32 to rotate the circumferential cutting tool around the wire axis, completing the circumferential cutting of the insulation layer; subsequently, activate several cutting linear slides 33 to drive the straight cutting servo cylinder 34 to feed radially, so that the peeling tool follows the circumferential cutting trajectory. Cut into the insulation layer and move along the conductor axis to peel off the insulation layer; after peeling off the insulation layer, start the ring-cutting servo cylinder 35 on the side of the processing frame 31 near the flipping frame 30 to drive the rubber pressure block to clamp the exposed part of the copper wire of the conductor; control the rotating frame 32 to rotate in the opposite direction for a preset number of turns, driving the copper wire to twist into a bundle to prevent the wire from being exposed during crimping; after the twisting is completed, the straight-cutting servo cylinder 34 drives the stripping cutter to reset, and the rubber pressure block is released; control the adjusting servo cylinder 27 to drive the flipping frame 30 to exit the conductor groove 20, and the lifting linear slide 26 drives the flipping frame 30 to descend to above the discharge port 36; start the flipping servo motor 29 to drive the flipping frame 30 to rotate 90°, so that the waste conductor sheath in the processing frame 31 falls into the discharge port 36 and is discharged outside the production frame 1 through the discharge channel 37.

[0038] Step 4: Activate the lower crimping servo cylinder 8 to drive the lower terminal mounting bracket 9 to rise until it is flush with the wire conveying plane, ensuring that the metal sheath of the lower half of the terminal is aligned with the crimping end of the wire; control the conveyor belt 15 to rotate slightly again, cooperating with the clamping and positioning of the clamping plate 25, to feed the crimping end of the wire after stripping and twisting into the interior of the metal sheath of the lower half of the terminal, ensuring that the edge of the insulation layer is aligned with the insulation crimping area of ​​the terminal; activate the upper crimping servo cylinder 7 to drive the upper terminal mounting bracket 9 to descend, so that the upper half of the terminal is precisely aligned with the lower half of the terminal; through the upper crimping servo... The coordinated pressurization of electric cylinder 7 and lower crimping servo electric cylinder 8 causes plastic deformation of the terminal metal sheath, completing the engagement of the conductor crimping area with the copper wire and the fixation of the insulation crimping area with the insulation layer, thus achieving a reliable connection between the wire and the terminal. If synchronous crimping of both ends of the terminal is required, steps 2 to 4 are repeated, and the wire conveying components 5 and crimping processing components 6 on both sides are used to synchronously complete the processing and crimping of the wires at both ends. If alternating continuous production is required, when the left side is crimped, the right side is simultaneously stripped and twisted. After the left side is unloaded, the right side is directly fed into the crimping station to achieve continuous processing.

[0039] Step 5: After crimping, control the clamping plate 25 to release the wires, start the winding servo motor 18, and its output shaft drives the drive gear 19 to rotate. Through the meshing transmission between the drive gear 19 and the annular tooth groove on the outer circumference of the rotating frame 16, the rotating frame 16 and the winding frame 17 are rotated by a preset angle, so that the multiple wires on the outside of the terminal are neatly wound. After the wire harness is wound, a cable tie is put on the outside of the wire harness and tightened to complete the binding and fixing of the wire harness and prevent the wires from being scattered. After binding, control the clamping plate 25 in the winding frame 17 to be completely released, and the finished cable harness assembly is removed from the winding frame 17 manually or by a robotic arm. At the same time, each motion mechanism is reset: the upper crimping servo cylinder 7 and the lower crimping servo cylinder 8 drive the terminal mounting frame 9 to open, the conveying servo cylinder 10 drives the conveying frame 11 to return to the initial position, and the flipping frame 30 is reset to the standby position, ready for the next batch of production.
