Technical Field

[0001] This invention belongs to the field of automotive manufacturing technology, specifically relating to a processing equipment and method for automotive wiring harness production. Background Technology

[0002] In the automotive manufacturing industry, automotive wiring harnesses, as a crucial component of the vehicle's electrical system, bear the critical responsibility of transmitting electrical energy and signals. With the increasing level of automotive electronics, the complexity and quantity of automotive wiring harnesses are also constantly increasing. Automotive wiring harnesses typically consist of multiple wires, which need to be precisely processed according to specific lengths and layouts to meet the connection requirements of various electrical devices within the vehicle.

[0003] Traditional automotive wiring harness production relies heavily on manual labor, including processes such as wire cutting, terminal crimping, harness assembly, and insulation wrapping. However, this method suffers from low production efficiency, inconsistent product quality, and high labor costs. Particularly in the wire cutting and terminal crimping stages, the precise control of wire length and terminal crimping position makes it difficult to guarantee consistency and accuracy during manual operation, easily leading to quality problems such as poor contact and short circuits.

[0004] In recent years, with the continuous development of automation technology, automotive wiring harness production equipment has gradually moved towards automation and intelligence. Automated production equipment can significantly improve production efficiency, reduce labor costs, and ensure the stability and consistency of product quality. However, existing automotive wiring harness production equipment still has some shortcomings in areas such as wire cutting, terminal crimping, and wiring harness assembly, including complex equipment structure, cumbersome operation, and high maintenance costs.

[0005] Furthermore, insulation treatment of wires is crucial during automotive wiring harness production. A good insulation layer effectively prevents short circuits between wires within the wiring harness, improving its overall stability and safety. However, traditional insulation methods are often inefficient and struggle to guarantee the uniformity and tightness of the insulation layer.

[0006] To address the aforementioned issues, a processing equipment for automotive wiring harness production is proposed to solve the problems of cumbersome traditional wiring harness production steps and high labor costs. Summary of the Invention

[0007] The purpose of this invention is to provide a processing equipment for automotive wiring harness production to solve the problems mentioned in the background art.

Several mounting grooves corresponding to the wire feeding grooves are formed on the inner wall of the connecting ring. The mounting grooves form a tangential channel with the wire feeding grooves. A telescopic rod is fixed at the bottom of the mounting groove. A blade is fixed at the output end of the telescopic rod.

[0013] The present invention further illustrates that the other end of the wire feeding roller faces the clamping assembly and is provided with a combing plate. The combing plate is conical, and the end face of the combing plate is fixed to the end face of the wire feeding roller. A combing groove is formed at the tip of the combing plate. A combing channel is formed on the inner wall of the combing groove facing each wire feeding groove. The combing channel corresponds to the position of the wire feeding groove. A plurality of clamping recesses are arrayed on the outer wall of the combing plate, and one clamping recess corresponds to one position of the wire feeding groove.

[0014] The present invention further illustrates that the top of the clamping plate two near the side of the feeding assembly is provided with a notch communicating with the clamping hole, and the notch is used for the tape to pass through.

[0015] The invention further describes that a support plate is fixed to both inner side walls of the base. The support plate is located below the sliding groove. A support rod is rotatably connected to the support plate. The support rod is located on one side of the feeding assembly. A rotating seat is fixedly connected to the support rod. A connecting rod is fixed to the side wall of the rotating seat. A C-shaped gripper is fixed to the other end of the connecting rod. An arc-shaped groove is formed at the opening of the C-shaped gripper. An arc-shaped plate is slidably connected in the arc-shaped groove.

[0016] The present invention further describes that an annular guide rail is provided on the outer side of the combing plate, the annular guide rail is fixed to the end face of the feed roller, a sliding block is slidably connected on the annular guide rail, a guide plate is provided on the sliding block, the side wall of the guide plate is hinged to the sliding block, and a fixed rotation drive is provided at the hinge of the sliding block 213 and the guide plate 214 to drive the guide plate 214 to rotate; a plurality of mounting holes are provided on the end face of the guide plate, a connecting rod is slidably connected to each mounting hole, a limit block is provided at the end of the connecting rod away from the combing groove, a spring is provided between the limit block and the mounting hole, and the spring is sleeved on the outside of the connecting rod;

[0017] The inner side wall of the base is also fixed with a terminal crimping worktable, which is located on the same side as the support rod relative to the feeding assembly.

[0018] The present invention further explains that the wires required to form the automotive wiring harness are connected to the wire feed channel through the wire inlet hole and the wires are transported through the wire feed channel; in the initial state, the two clamping components are located between the feeding component and the sealing component. When the wires are output from the feeding component, all the wires will come together to form a wire harness and pass through the clamping component near the feeding component and be clamped by the clamping component near the sealing component. The clamping component in the sliding clamping state drives the wire harness to move towards the sealing component. When the wire harness passes through the sealing component, the sealing component will wrap an insulating layer on the surface of the wire harness.

[0019] The present invention further explains that, during the process of the wire being transported in the cable tray, the length of the wire being transported in the cable tray is calculated. When the length of the wire being transported in the cable tray reaches the required length, the telescopic rod is activated, and the telescopic rod drives the blade to move in the direction of the wire to cut the wire.

[0020] The present invention further explains that when the cut wire is about to be discharged from the wire feeding roller by the wire feeding groove, the wire feeding roller is rotated so that the wire feeding groove where the cut wire is located is close to the C-shaped gripper. The motor is started, and the output end of the motor drives the support rod and the rotating seat to rotate. The rotating seat drives the C-shaped gripper to rotate until it is in contact with the end face of the wire feeding roller. At this time, the cut wire is located in the opening of the C-shaped gripper. The arc plate is driven by the cylinder to slide so that the C-shaped gripper and the arc plate form a wire channel to wrap the wire. The wire is fixed by starting the micro cylinder.

[0021] The present invention further explains that when the cut wire is re-conveyed by the wire feeding trough and enters the next production stage of the automotive wiring harness, when the top end of the wire is discharged from the wire feeding roller, one end of the wire is rotated to the terminal crimping workbench by the C-shaped gripper to crimp the terminal. After crimping, the C-shaped gripper releases its grip on the wire, and the wire hangs down under the action of gravity. The sliding block slides on the annular guide rail by activating the annular guide rail. During the sliding process of the sliding block, the connecting rod contacts the wire and lifts the wire to a horizontal position. By rotating the wire plate in the direction of the comb plate axis, the connecting rod is brought into contact with the opening edge of the comb groove, and the wire is slowly pressed into the comb groove and converges with the wiring harness. The wire and the wiring harness are fixed by the clamping assembly near the wire feeding roller.

[0022] Compared with existing technologies, the beneficial effects achieved by this invention are as follows: This invention, through automated operation, achieves seamless integration of processes such as continuous wire feeding, cutting, terminal crimping, and wire harness assembly, significantly improving production efficiency. Compared with traditional manual operation methods, this equipment can greatly shorten the production cycle and meet the needs of large-scale production;

[0023] The introduction of automated production equipment reduces manual operations and lowers the skill requirements for operators, thereby effectively reducing labor costs. Furthermore, the stable operation of the equipment reduces production failures and product quality issues caused by human factors, further lowering production costs.

[0024] This equipment can adapt to the production needs of different specifications and types of automotive wiring harnesses by adjusting the parameters and configurations of modules such as the feeding and clamping components. This flexibility allows the equipment to be widely used in various automotive wiring harness production scenarios, improving equipment utilization and return on investment.

[0038] The following detailed, non-limiting description of the technical solution of the present invention, in conjunction with preferred embodiments and accompanying drawings, is provided. Obviously, the described embodiments are merely some, not all, of the embodiments of the present invention. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without inventive effort are within the scope of protection of the present invention.

[0039] Please see Figure 1-10The present invention provides a technical solution: a processing equipment and method for automotive wiring harness production, comprising a base 1, a support seat 101 fixed at one end of the base 1 and a wiring harness outlet 5 fixed at the other end, the wiring harness outlet 5 being used to produce processed wiring harnesses, a feeding assembly 2 being rotatably connected to the side wall of the support seat 101, sliding grooves 102 being fixed on the side walls of the base 1, two clamping assemblies 3 being slidably connected between the two sliding grooves 102, the clamping assemblies 3 sliding between the feeding assembly 2 and the wiring harness outlet 5, a sealing assembly 4 and a thermoforming machine 6 being fixed on the sliding grooves 102, the clamping assembly 3 being close to the feeding assembly 2 and being used to clamp the processed wiring harness, the sealing assembly 4 being close to the wiring harness outlet 5 and being used to wrap the wiring harness with an insulation layer, and the thermoforming machine 6 being used to thermoform the insulation layer wrapped in the wiring harness, making it tightly adhere to the surface of the wiring harness, improving the insulation effect and the overall stability of the wiring harness.

[0040] The feeding assembly 2 includes a wire feeding roller 201, one end of which is rotatably connected to the support base 101. A plurality of wire feeding grooves 202 are arranged in a central array on the end face of the wire feeding roller 201 near the support base 101, and these grooves extend through the roller to the other end face. A plurality of wire inlet holes 203 are arranged in an array along the outer wall of the wire feeding roller 201, near the support base 101. The number of wire inlet holes 203 corresponds to the number of wire feeding grooves 202, and each wire inlet hole 203 corresponds in position to and communicates with one wire feeding groove 202.

[0041] The wires required to form the automotive wiring harness are connected to the wire feed channel 202 through the wire inlet 203 and then fed through the wire feed channel 202. In the initial state, the two clamping components 3 are located between the feeding component 2 and the sealing component 4. When the wires are output from the feeding component 2, all the wires will come together to form a wire harness and pass through the clamping component 3 near the feeding component 2. The clamping component 3 near the sealing component 4 will clamp the wire harness. The clamping component 3 in the sliding clamping state will drive the wire harness to move towards the sealing component 4. When the wire harness passes through the sealing component 4, the sealing component 4 will wrap an insulating layer on the surface of the wire harness.

[0042] The outer wall of the wire feeding roller 201 is provided with an annular groove 204 that communicates with a plurality of wire feeding grooves 202. The annular groove 204 is located in the middle of the wire feeding roller 201. A connecting ring 205 is provided in the annular groove 204. The connecting ring 205 is fixedly connected to the wire feeding rollers 201 on both sides. The inner wall of the connecting ring 205 is provided with a plurality of mounting grooves 206 corresponding to the wire feeding grooves 202. The mounting grooves 206 and the wire feeding grooves 202 form a tangential channel. A telescopic rod 207 is fixed at the bottom of the mounting groove 206. A blade 208 is fixed at the output end of the telescopic rod 207. The blade 208 is used to cut the wire bundle in the tangential channel.

[0043] The other end of the wire feeding roller 201 faces the clamping assembly 3 and is provided with a combing plate 209. The combing plate 209 is conical, and the end face of the combing plate 209 is fixed to the end face of the wire feeding roller 201. A combing groove 210 is opened at the tip of the combing plate 209. A combing channel 211 is opened on the inner wall of the combing groove 210 facing each wire feeding groove 202. The combing channel 211 corresponds to the position of the wire feeding groove 202.

[0044] Furthermore, the outer wall of the comb plate 209 is provided with a plurality of clamping recesses 2091, each clamping recess 2091 corresponding to a wire feed groove 202, so as to facilitate the clamping assembly 3 to clamp the wire harness.

[0045] During the transmission of wires within the cable tray 202, unlike the wires in an optical cable where each wire is of equal length, the wires in the cable harness extend from the middle of the harness and are crimped to terminals for connection with components within the vehicle. Therefore, each wire needs to be cut at a fixed length. By calculating the length of the wires transported by the cable tray 202, when the required length is reached, the telescopic rod 207 is activated. The telescopic rod 207 drives the blade 208 to move towards the wire, cutting it off.

[0046] Support plates 230 are fixed to both inner side walls of the base 1. The support plates 230 are located below the sliding groove 102. A support rod 219 is rotatably connected to the support plates 230. The support rod 219 is located on one side of the feeding assembly 2. A rotating seat 220 is fixedly connected to the support rod 219. A connecting rod 222 is fixed to the side wall of the rotating seat 220. A C-shaped gripper 223 is fixed to the other end of the connecting rod 222. An arc-shaped groove 224 is opened at the opening of the C-shaped gripper 223. An arc-shaped plate 225 is slidably connected in the arc-shaped groove 224. The arc-shaped plate 225 and the C-shaped gripper 223 have the same curvature. The arc-shaped plate 225 extends out and contacts the other opening of the C-shaped gripper 223, thereby forming a closed wire clamping channel.

[0047] The C-shaped gripper 223 is also provided with a cylinder mounting groove 226 that communicates with the arc-shaped groove 224. A cylinder 227 is provided in the cylinder mounting groove 226. The output end of the cylinder 227 communicates with the inside of the arc-shaped groove 224, and the input end of the cylinder 227 passes through the C-shaped gripper 223 and communicates with the outside.

[0048] A miniature cylinder 228 is fixed at the middle position of the arc-shaped inner wall of the C-type gripper 223. A clamping plate 229 is fixed at the output end of the miniature cylinder 228. During operation, the arc-shaped plate 225 is driven to slide by the cylinder 227, which in turn drives the clamping plate 229 with the miniature cylinder 228. The two work together to clamp the wire.

[0049] A motor 221 is fixed below the support plate 230. The output end of the motor 221 passes through the support plate 230 and is fixedly connected to the support rod 219. The motor 221 drives the support rod 219 and the rotating seat 220 to rotate.

[0050] When the cut wire is about to be discharged from the wire conveying roller 201 through the wire conveying groove 202, the wire conveying roller 201 is rotated so that the wire conveying groove 202 containing the cut wire is located close to the C-shaped gripper 223. The motor 221 is started, and the output end of the motor 221 drives the support rod 219 and the rotating seat 220 to rotate. The rotating seat 220 drives the C-shaped gripper 223 to rotate until it is in contact with the end face of the wire conveying roller 201. At this time, the cut wire is located in the opening of the C-shaped gripper 223. The cylinder 227 drives the arc plate 225 to slide so that the C-shaped gripper 223 and the arc plate 225 form a wire channel to wrap the wire. The wire is fixed by starting the micro cylinder 228.

[0051] The inner side wall of the base 1 is also fixed with a terminal crimping worktable 231, which is located on the same side as the support rod 219 relative to the feeding assembly 2.

[0052] Rotate the support rod 219 again to rotate one end of the cut wire to the terminal crimping workbench 231 and crimp the terminal.

[0053] An annular guide rail 212 is provided on the outer side of the comb plate 209. The annular guide rail 212 is fixed to the end face of the feed roller 201. A sliding block 213 is slidably connected to the annular guide rail 212. The annular guide rail 212 is an electric guide rail. When energized, it drives the sliding block 213 to slide along the annular guide rail 212. A guide plate 214 is provided on the sliding block 213. The side wall of the guide plate 214 is hinged to the sliding block 213. By hinged to the sliding block 213, the guide plate 214 moves towards the comb groove 210. The hinge point between the sliding block 213 and the guide plate 214 is fixed and rotated to drive the guide plate 214 to rotate.

[0054] The end face of the conductor plate 214 is provided with a plurality of mounting holes 215, and a connecting rod 216 is slidably connected to each mounting hole 215. A limit block 217 is provided at the end of the connecting rod 216 away from the comb groove 210. A spring 218 is provided between the limit block 217 and the mounting hole 215, and the spring 218 is sleeved on the outside of the connecting rod 216.

[0055] Furthermore, a housing 7 is fitted onto the base 1. The housing 7 is used to protect the internal processing equipment. Several windows 701 are provided on the housing 7, through which the internal situation can be observed.

[0056] In the automotive wiring harness production process, when the cut wire is re-conveyed by the wire feed trough 202 and enters the next automotive wiring harness production stage, as the top end of the wire exits from the wire feed roller 201, one end of the wire is rotated by the C-type gripper 223 to the terminal crimping worktable 231 for crimping. After crimping, the C-type gripper 223 releases its grip on the wire, and the wire hangs down under the action of gravity. By activating the annular guide rail 212, the sliding block 213 slides clockwise on the annular guide rail 212. During the sliding process, the connecting rod 216 abuts against the surface of 209. When the sliding block 213 slides to the bottom of the annular guide rail 212, the sliding block 213 continues to slide. The lateral movement of 13 is towards the direction in which the wire falls, and the longitudinal movement is upward. During the sliding of the sliding block 213, the connecting rod 216 comes into contact with the wire. Since the connecting rod 216 also moves upward, it lifts the wire. During this process, the wire is restricted by the comb plate 209 and the wire plate 214 to prevent the wire from falling around the top of the connecting rod 216 until the wire is lifted to the horizontal. The wire plate 214 is rotated in the direction of the comb plate 209 axis by rotation drive, so that the connecting rod 216 fits against the opening edge of the comb groove 210 and slowly presses the wire into the comb groove 210 and converges with the wire bundle. The clamping assembly 3 near the wire feed roller 201 fixes the wire and the wire bundle.

[0057] The two clamping components 3 include a sliding plate 301, on which a second clamping plate 302 is fixed. A clamping hole 303 is formed on the end face of the second clamping plate 302. A plurality of mounting grooves 304 are arrayed on the inner wall of the clamping hole 303. An electric push rod 305 is fixed in the plurality of mounting grooves 304. A clamping block 306 is fixed at the output end of the electric push rod 305. The clamping block 306 faces the center of the clamping hole 303. The electric push rod 305 is started by electric synchronous drive to cause the plurality of clamping blocks 306 to clamp inward simultaneously.

[0058] The top of the clamping plate 302 near the side of the feeding assembly 2 is provided with a notch 307 that communicates with the clamping hole 303, and the notch 307 is used for the tape to pass through.

[0059] The sealing assembly 4 includes an upper arc-shaped sliding plate 401 and a lower arc-shaped sliding plate 402. The upper arc-shaped sliding plate 401 and the lower arc-shaped sliding plate 402 are respectively fixed to the upper and lower sides of the sliding groove 102 to form a circular enclosure. The inner walls of the upper arc-shaped sliding plate 401 and the lower arc-shaped sliding plate 402 are provided with a second sliding groove 403. The second sliding groove 403 does not contact the first sliding groove 102 and is located inside it. A sealing plate 404 is slidably connected in the second sliding groove 403.

[0060] The sealing plate 404 is hollow and semi-circular inside. The two sides of the end face of the sealing plate 404 are provided with mounting grooves 405 through the outer wall. Two drive wheels 406 are rotatably connected in the mounting grooves 405. The sealing plate 404 slides in the upper arc-shaped slide plate 401 and the lower arc-shaped slide plate 402 through the drive wheels 406.

[0061] The sealing plate 404 has a mating groove 407 at the center of its end face, which communicates with the interior. The mating groove 407 is adapted to the shape of the clamping plate 302. The mating groove 407 is used to allow the clamping assembly 3 to slide normally within the sliding groove 102.

[0062] An installation rod 408 is fixed inside the sealing plate 404. An adhesive tape 409 is rotatably connected to the outside of the installation rod 408. The adhesive tape 409 is pulled out from the mating groove 407 when sealing is required.

[0063] During the wire harness processing, one end of the tape 409 is wrapped around the surface of the wire harness. By activating the drive wheel 406, the drive wheel 406 drives the sealing plate 404 to slide inside the sliding groove 403 and rotate around the wire harness, so that the tape 409 is evenly wrapped around the surface of the wire harness.

[0064] Working principle: During the wire harness processing, the wires required to form the automotive wire harness are fed into the wire delivery groove 202 through the wire inlet 203 and then transported through the wire delivery groove 202. In the initial state, the two clamping components 3 are located between the feeding component 2 and the sealing component 4. When the wires are output from the feeding component 2, all the wires will come together to form a wire harness and pass through the clamping component 3 near the feeding component 2. The clamping component 3 near the sealing component 4 will then clamp the wire harness. The clamping component 3 in the sliding clamping state will drive the wire harness to move towards the sealing component 4. When the wire harness passes through the sealing component 4, the sealing component 4 will wrap an insulating layer on the surface of the wire harness. Due to the presence of the notch 307, the tape 409 will pass through the notch 307.

[0065] During the transmission of wires within the cable tray 202, unlike the wires in an optical cable where each wire is of equal length, the wires in the cable harness extend from the middle of the harness and are crimped to terminals for connection with components within the vehicle. Therefore, each wire needs to be cut at a fixed length. By calculating the length of the wires transported by the cable tray 202, when the required length is reached, the telescopic rod 207 is activated. The telescopic rod 207 drives the blade 208 to move towards the wire, cutting it off.

[0066] When the cut wire is about to be discharged from the wire conveying roller 201 through the wire conveying groove 202, the wire conveying roller 201 is rotated so that the wire conveying groove 202 containing the cut wire is located close to the C-shaped gripper 223. The motor 221 is started, and the output end of the motor 221 drives the support rod 219 and the rotating seat 220 to rotate. The rotating seat 220 drives the C-shaped gripper 223 to rotate until it is in contact with the end face of the wire conveying roller 201. At this time, the cut wire is located in the opening of the C-shaped gripper 223. The cylinder 227 drives the arc plate 225 to slide so that the C-shaped gripper 223 and the arc plate 225 form a wire channel to wrap the wire. The wire is fixed by starting the micro cylinder 228.

[0067] When the cut wire is re-fed by the wire feeding trough 202 and enters the next stage of automotive wiring harness production, as the top end of the wire is discharged from the wire feeding roller 201, one end of the wire is rotated to the terminal crimping worktable 231 by the C-type gripper 223 to crimp the terminal. After crimping, the C-type gripper 223 releases its grip on the wire, and the wire hangs down under the action of gravity. The sliding block 213 slides on the annular guide rail 212 by activating the annular guide rail 212. During the sliding of the sliding block 213, the connecting rod 216 contacts the wire and lifts the wire to a horizontal position. By rotating the wire plate 214 in the direction of the comb plate 209 axis, the connecting rod 216 is brought into contact with the opening edge of the comb groove 210, and the wire is slowly pressed into the comb groove 210 and converges with the wiring harness. The clamping assembly 3 near the wire feeding roller 201 fixes the wire to the wiring harness.

[0068] When it is necessary to wrap tape 409 around the wire harness, one end of tape 409 is wrapped around the surface of the wire harness. By activating drive wheel 406, drive wheel 406 drives sealing plate 404 to slide inside sliding groove 403 and rotate around the wire harness, so that tape 409 is evenly wrapped around the surface of the wire harness.
