Description

Technical Field

[0001] This invention belongs to the field of automotive wiring harness connection technology, specifically referring to an automotive wiring harness terminal processing device. Background Technology

[0002] Automotive wiring harnesses are the main network of automotive circuits, equivalent to the "neural network" and "blood vessels" of a car. They are responsible for transmitting power and signals between various components such as the engine, chassis, body, and electronic appliances, and are the core foundation for the normal operation of the automotive electrical system.

[0003] Existing automotive wiring harness terminal processing equipment is mostly of a step-by-step structure, which suffers from poor processing continuity, insufficient wiring harness positioning accuracy, and weak compatibility with multiple wiring harness specifications. This results in low processing efficiency, unstable terminal crimping and connection quality, and susceptibility to faults such as excessive wire stripping damaging the wire core and crimping deviation leading to poor contact. It cannot meet the high-precision, high-efficiency batch processing requirements of automotive wiring harnesses. Furthermore, the traditional equipment suffers from poor coordination between modules such as feeding, stripping, and crimping, requiring significant manual intervention, increasing labor costs and processing errors, and making it difficult to adapt to the automated production requirements of modern automotive manufacturing. Summary of the Invention

Addressing the problems of poor processing continuity, insufficient compatibility with multiple wiring harness specifications, and low positioning accuracy in existing devices, this invention adopts an island-style integrated layout and a magnetic cooperative positioning method. It incorporates a multi-module surrounding conveying mechanism and adaptive clamping components, achieving fully automated and continuous processing of the entire process from wire harness feeding, stripping, crimping, to terminal connection. This solves the technical problems of low efficiency in step-by-step processing and poor processing quality due to positioning deviations. To solve the problems of easy damage to the wire core during wire harness stripping and untimely waste insulation recovery, this invention creatively proposes a rotary ring-cutting and stripping mechanism. This mechanism uses gear meshing to drive the stripping roller to rotate, simultaneously stripping the wire harness sheath after the circumferential cutting arm, achieving precise ring cutting, damage-free stripping, and real-time waste insulation recovery.

[0055] In practical use, first load the wire harness onto the feeding module 1, then pass the wire harness sequentially through the pulley clamp 106 and the wire harness clamp 105 at the same horizontal height. Multiple sets of wire harnesses of different specifications can be installed from bottom to top in the same way. The wire harness can directly pass through the compression pulley 132 of the pulley clamp 106. When the wire harness passes through the wire harness clamp 105, press the compression base 125. The compression base 125 pushes the compression roller 124 outward (away from the compression base 122) through the wire clamping connecting rod 123. The compression spring 126 is compressed by the wire clamping base 122 and the compression base 125. The compression roller 124 pushes the wire clamping slide outward. Plate 127 and return spring 129 are compressed and shortened by clamping slide plate 127, and the distance between clamping roller 124 and clamping base 122 increases. At this time, the wire harness can pass through the clamping base 122 and clamping roller 124. After the wire harness passes through two sets of wire harness clamps 105 at the same height, the clamping base 125 is released, and the clamping spring 126 returns to its original extension to push the clamping rod 123, clamping roller 124 and clamping base 125 to slide inward as a whole. The clamping roller 124 and clamping base 122 are respectively close to both sides of the wire harness. The return spring 129 extends to push the clamping slide plate 127 to close to the wire harness, thus completing the fixation of the wire harness.Processing begins with the loading operation. Two sets of wire feeding devices 104 start simultaneously with identical operating steps. The wire feeding cylinder 110 extends, pushing the wire feeding slide 112 to slide, allowing the outer side of the rubber toothed belt 120 to press tightly against the side of the wire harness. In one set of wire feeding devices 104, the wire feeding slide 112 has opening and closing permanent magnets 113 on both sides. The opening and closing permanent magnets 113 press tightly against the outer walls of the two sets of wire clamps 105, attracting the metal suction plate 128. The metal suction plate 128 drives the wire clamping slide plate 127 away from the wire harness, and the return spring 129 is compressed and shortened by the wire clamping slide plate 127. At this time, the wire clamp 105 contains the wire clamping base 122 and the compression roller 127. 24. The wire harness is restricted, and the wire feeding servo motor 119 is started. The wire feeding servo motor 119 drives the wire feeding transmission gear 118 to rotate. The rotation of the wire feeding transmission gear 118 drives the wire feeding follower gear 117 to rotate. The rotation of the wire feeding follower gear 117 drives the wire feeding follower shaft 116 to rotate. The rotation of the wire feeding follower shaft 116 drives the drive wheel 115 to rotate. The rotation of the drive wheel 115 drives the rubber toothed belt 120 to rotate. The rubber toothed belts 120 of the two sets of wire feeding devices 104 drive the wire harness for feeding. The wire feeding servo motor 119 controls the feeding length of the wire harness. During feeding, the front end of the wire harness first passes through the wire cutter 133 and the magnetic base 523 on one side, and the upper clamping teeth 523 in sequence. 24. Activate the transfer cylinder 513. The transfer cylinder 513 extends and pushes the sliding shaft 512, rotary joint 516, and magnetic clamp 517 downwards together via the synchronous push arm 515. Activate the magnetic clamp 517 to hold the end of the wire harness. Activate the rotary motor 511, which drives the sliding shaft 512 to rotate. The rotation of the sliding shaft 512 drives the rotary joint 516 and magnetic clamp 517 to rotate. The magnetic clamp 517 rotates 180 degrees around the vertical axis of the sliding shaft 512, sending the end of the wire harness between the magnetic base 523 and the upper clamping teeth 524 on the other side (far wire side). Activate the magnetic base 523 on the other side (far wire side). 23. The magnetic base 523 attracts the upper clamping teeth 524, which slide downwards. The upper clamping teeth 524 and the magnetic base 523 are used to fix the front end of the wire harness. The magnetic clamp 517 releases the clamp on the wire harness. The transfer cylinder 513 retracts and resets. The rotating motor 511 drives the sliding shaft 512 to reset. After the wire harness is transported, the magnetic base 523 on one side (near the wire side) is activated. The upper clamping teeth 524 and the magnetic base 523 on this side are used to fix the rear end of the wire harness. The wire cutter 133 is activated to cut the wire harness. The wire cutting cylinder 137 is activated. The wire cutting cylinder 137 extends and pushes the oblique cutter 136. The oblique cutter 136 and the flat cutter 135 are used to cut the rear end of the wire harness.After the cutting is completed, the stripping operation begins. The conveyor motor 507 is started, which drives the conveyor gear 506 to rotate. The rotation of the conveyor gear 506 drives the conveyor gear ring 505 to rotate, which in turn drives the conveyor turntable 502 to rotate. At this time, the conveyor 503 carrying the wire harness is rotated to the processing position of the stripping module 2. The docking air rod 509, which is aligned with the stripping module 2, is activated. The docking air rod 509 extends and pushes the upper sliding cover 521 to slide. The sliding spring 518 is compressed and shortened by the sliding base 520 and the upper sliding cover 521. The upper sliding cover 521 drives the two sets of magnetic bases 523 and the upper clamping teeth 524 to slide, thus moving the front and rear of the wire harness. The wire harness is fed into the wire stripper 202. The processing steps at the front and rear ends are the same. The ends of the wire harness pass through the stripping blade 212 and the stripping roller 208 in sequence. The stripping motor 211 is started, which drives the rotating frame 206 to rotate. The rotation of the rotating frame 206 drives the cutting arm 207 to rotate. During the rotation of the cutting arm 207, the stripping blade 212 at the end of the cutting arm 207 will circumferentially cut the outer sheath of the wire harness. At the same time, since the stripping gear 209 is meshed with the stripping tooth ring 210, the rotation of the rotating frame 206 will drive the stripping roller 208 to rotate. The rotation of the stripping roller 208 will separate the circumferentially cut outer sheath from the wire harness. After the outer sheath enters the recycling channel 203 through the waste discharge channel 205, the stripping is completed, the docking air rod 509 resets, and the sliding spring 518 extends to drive the upper sliding cover 521 to reset. After the stripping operation is completed, the crimping operation is performed. The conveyor motor 507 is started, and the conveyor turntable 502 is driven to rotate, rotating the conveyor 503 carrying the wire harness to the processing position of the crimping module 3. The copper tube at the end of the wire harness is conveyed in the crimping chamber 302. The docking air rod 509, which is aligned with the crimping module 3, is started to send the front and rear ends of the wire harness into the crimping chamber 302. The end of the wire harness is inserted into the copper tube. The crimping hydraulic arm 307 is started, and the crimping hydraulic arm is activated. Arm 307 pushes the sliding pressure plate 304 downwards, using the pressing teeth 305 and the bottom pressure plate 303 to deform the copper tube, and using the cutting teeth 306 and the bottom pressure plate 303 to cut the copper tube. After completing the crimping operation, the docking air rod 509 is reset. For the connection operation, the conveyor motor 507 is started, driving the conveyor turntable 502 to rotate, rotating the conveyor 503 carrying the wire harness to the processing position of the connection module 4. The docking air rod 509, aligned with the connection module 4, is started, extending to feed the front and rear ends of the wire harness into the terminals of the terminal channel 401. The terminal channel 401 then transports the wire harness to the connected terminals.
