Description
Automotive wiring harness manufacturing equipment and processing method Technical Field
[0001] This application relates to the technical field of wire harness processing, and in particular to an automotive wire harness production and processing equipment and method. Background Technology
[0002] Automotive wiring harnesses are the core of a vehicle's electrical network; without them, there is no automotive electrical system. A wiring harness is an assembly consisting of copper-formed contact terminals (connectors) crimped to electrical wires and cables, then covered with a molded insulator or an outer metal shell, and bundled together to form a connected circuit. During manufacturing, automotive wiring harnesses require cutting to meet the specific connection needs of different vehicles.
[0003] Currently, most methods for cutting wire harnesses involve first unwinding the coiled wires, then manually measuring and cutting them. However, manual measurement has a large margin of error, resulting in low precision in wire harness cutting. Summary of the Invention
[0004] To improve the cutting accuracy of wire harnesses, this application provides automotive wire harness manufacturing equipment and processing method.
[0005] In the first aspect, this application provides an automotive wiring harness manufacturing and processing equipment, which adopts the following technical solution:
[0006] An automotive wiring harness manufacturing and processing equipment includes a base, a worktable fixedly connected to the base, a wire feeding assembly for separating coils on one side of the worktable, a movable seat on the side of the worktable away from the wire feeding assembly, a wire clamping assembly for pulling the wiring harness on the movable seat, a traveling screw rotatably connected inside the worktable, the traveling screw passing through the movable seat and the two being threaded together, a guide rod fixedly connected to the side wall of the worktable facing the movable seat, the guide rod passing through the movable seat and the two being slidably adapted to each other, a first drive motor for driving the traveling screw to rotate on one side of the worktable, and a cutting assembly for cutting the wiring harness on the worktable.
[0007] Using the above technical solution, after the wire feeding assembly separates the coil, the wire clamping assembly pulls the end of the wire bundle until the length of the wire bundle is pulled to the required length. At this point, the cutting assembly starts to cut the wire bundle. Through this structure, the operator can adjust the first drive motor to make the displacement along the limit rod different, thereby obtaining wire bundles of different lengths, eliminating the need for manual measurement and improving the cutting accuracy.
[0008] Optionally, the wire clamping assembly includes a fixed base, a first bidirectional lead screw, and clamping rods. The fixed base is disposed between the movable base and the worktable. One side of the fixed base is fixedly connected to the movable base. Two hanging plates are fixedly connected to the side of the fixed base facing the base. The first bidirectional lead screw is rotatably connected between the two hanging plates. A second drive motor for driving the first bidirectional lead screw to rotate is installed on the hanging plates. Both ends of the first bidirectional lead screw are threadedly connected to a first base. The number of clamping rods is the same as the number of first bases and corresponds one-to-one. The clamping rods are fixedly connected to the first bases. A limit rod is fixedly connected between the two hanging plates. The limit rod passes through the two first bases and is slidably adapted to both first bases.
[0009] Using the above technical solution, the second drive motor starts and, through the first bidirectional lead screw, causes the two first bases to move towards each other, thereby bringing the two clamping rods closer together until they clamp one end of the wire harness. After cutting, the second drive motor starts again and rotates in the opposite direction, causing the first bidirectional lead screw to move the two clamping rods away from each other through the first bases, thus releasing the wire harness. This structure achieves the effects of pulling the wire harness and releasing it promptly after cutting.
[0010] Optionally, a circumferential cutting seat is provided on the side of the fixed seat facing the base. A support rod is fixedly connected between the circumferential cutting seat and the fixed seat. Multiple first blade holders are provided inside the circumferential cutting seat. The multiple first blade holders are evenly spaced around the central axis of the circumferential cutting seat. A circumferential cutting blade is installed in the first blade holder. A circumferential cutting rod is fixedly connected to the side of the first blade holder away from the circumferential cutting blade. The circumferential cutting rod passes through the circumferential cutting seat and extends to the outside. A circumferential cutting spring is fixedly connected between the first blade holder and the circumferential cutting seat. A transmission component for driving the circumferential cutting rod is provided on the side of the fixed seat facing the circumferential cutting seat.
[0011] Using the above technical solution, during the clamping process of the two clamping rods, the circumferential cutting rod is compressed by the transmission component. At this time, the circumferential cutting spring is in a stretched state, and the compression of the circumferential cutting rod causes the circumferential cutting blade to approach the outer sheath of the wire harness. Thus, multiple circumferential cutting blades work together to complete the circumferential cutting of the wire harness end. During the process of tidying up the wire harness, the workers can simply peel off the outer sheath cut off by the circumferential cutting, which provides convenience for the workers.
[0012] Optionally, the transmission assembly includes a trigger sleeve and a trigger rod. The trigger sleeve is fitted onto the annular cut seat. A guide block is fixedly provided on the inner wall of the trigger sleeve. A guide groove is provided on the outer wall of the annular cut seat to slide and adapt to the guide block. A guide rod is fixedly connected to the annular cut seat in the guide groove. The guide rod passes through the guide block and is slidably adapted to the guide block. A return spring is provided in the guide groove. The two ends of the return spring are fixedly connected to the guide block and the annular cut seat, respectively. The number of trigger rods is the same as the number of first bases and corresponds one-to-one. The trigger rods are fixedly connected to the first bases and are used to press the trigger sleeve.
[0013] Using the above technical solution, during the process of clamping the end of the wire harness with the two clamping rods, the first base compresses the trigger sleeve through the trigger rod. At this time, the return spring is in a compressed state, thereby the trigger sleeve compresses the circumferential cutting rod. After the outer sheath of the wire harness end is circumferentially cut, the first base moves the trigger rod away from the trigger sleeve, and the return spring releases its elastic force to reset the trigger sleeve. Through the above structure, the effects of the trigger sleeve compressing the circumferential cutting rod and the trigger sleeve resetting are achieved.
[0014] Optionally, the first tool holder includes a first mounting base and a first mounting bolt. The first mounting base is fixedly connected to the circumferential cutting rod. A first mounting groove is provided on the side of the first mounting base away from the circumferential cutting rod. The circumferential cutting blade is disposed in the first mounting groove. One end of the first mounting bolt extends into the first mounting groove and abuts against the circumferential cutting blade. The first mounting bolt is threadedly connected to the first mounting base.
[0015] Using the above technical solution, when the circumferential cutting blade needs to be replaced or repaired, the operator can simply unscrew the first mounting bolt to remove the blade from the first blade holder. After replacement or repair, the operator places the circumferential cutting blade in the first mounting slot and then secures it with the first mounting bolt. This structure facilitates convenient replacement or repair of the circumferential cutting blade for the operator.
[0016] Optionally, the cutting assembly includes a second bidirectional lead screw and a cutting blade. A storage cavity is provided on the surface of the worktable facing the movable seat. The second bidirectional lead screw is rotatably connected in the storage cavity of the worktable. A third drive motor for driving the second bidirectional lead screw to rotate is installed on the worktable. Both ends of the second bidirectional lead screw are threaded to a second base. A second blade holder is fixedly connected to one side of the second base, and the cutting blade is installed in the second blade holder.
[0017] Using the above technical solution, after the wire clamping assembly pulls the wire harness to the required length, the third drive motor starts and causes the two second bases to move towards each other through the second bidirectional lead screw, thereby bringing the two cutting blades closer together and cutting the wire harness.
[0018] Optionally, the second blade holder includes a second mounting base and a second mounting bolt. The second mounting base is fixedly connected to the second base. The two second mounting bases have second mounting grooves on their opposite sidewalls. The cutting blade is disposed in the second mounting groove. One end of the second mounting bolt extends into the second mounting groove and abuts against the cutting blade. The second mounting bolt is threadedly connected to the second mounting base.
[0019] Using the above technical solution, when the cutting blade needs to be replaced or repaired, the worker can simply unscrew the second mounting bolt to remove the cutting blade from the second blade holder; after replacement or repair, the worker places the cutting blade in the second mounting slot and then secures it with the second mounting bolt. This structure facilitates convenient replacement or repair of the cutting blade for the worker.
[0020] Optionally, the wire feeding assembly includes a column and a rotating roller. The column is fixedly connected to the base, and one end of the rotating roller is rotatably connected to the column. A fourth drive motor for driving the rotating roller to rotate is installed on the column. The coil is sleeved on the rotating roller, and a fixing sleeve and a limiting sleeve are respectively provided on both sides of the coil. Both the fixing sleeve and the limiting sleeve are sleeved on the rotating roller. The fixing sleeve is fixedly connected to the rotating roller, and the limiting sleeve is threadedly connected to the rotating roller. The limiting sleeve presses the coil and the fixing sleeve together.
[0021] Using the above technical solution, during the process of the wire clamping assembly pulling the wire harness, the fourth drive motor starts to rotate the roller, thereby clamping the coil through the fixing sleeve and the limiting sleeve. The roller then rotates the coil, thus separating it. After the previous coil is cut, the worker unscrews the limiting sleeve, making it easy to replace with a new coil.
[0022] Optionally, a fixing plate is provided on the side of the workbench away from the base, and a support plate is fixedly connected between the fixing plate and the workbench. A telescopic cylinder is installed on the surface of the fixing plate facing the workbench, and a pressure block is fixedly connected to the end of the telescopic cylinder.
[0023] Using the above technical solution, after the wire clamping assembly pulls the wire harness to the required length, the telescopic cylinder is activated to press the wire harness tightly through the pressure block, making it difficult for the wire harness to move. This facilitates the wire clamping assembly to clamp and fix the wire harness next time.
[0024] Secondly, this application provides a method for manufacturing and processing automotive wiring harnesses, employing the following technical solution:
[0025] A method for manufacturing automotive wiring harnesses includes the following steps:
[0026] S1. The worker installs the coil inside the wire feeding assembly, and then pulls the end of the coil to the workbench;
[0027] S2. The first drive motor starts and brings the wire clamping assembly close to the worktable. After one end of the wire harness is between the two clamping rods, the second drive motor starts and clamps the end of the wire harness. At the same time, the outer sheath of the end of the wire harness is cut. Then the first drive motor starts again and pulls the wire harness to the required length.
[0028] S3. After pulling the wire harness to the required length, the third drive motor starts, and at this time the two cutting blades move towards each other to cut the wire harness.
[0029] S4 and S2-S3 are repeated until the entire coil is cut.
[0030] S5. After the previous coil is cut, replace it with a new coil and start the operation again from S1.
[0031] In summary, this application includes at least one of the following beneficial technical effects:
[0032] 1. The first drive motor starts and moves the wire clamping assembly toward the worktable until the end of the wire harness is between the two clamping rods. At this time, the second drive motor starts and clamps the wire harness through the clamping rods. At the same time, the transmission assembly causes the ring cutter to ring cut the outer sheath of the end of the wire harness. Then the first drive motor starts again and pulls the wire harness to the required length. At this time, the third drive motor starts and cuts the wire harness through the cutting blade. Through the above structure, the cutting accuracy is improved.
[0033] 2. The ring cutter and the cutting blade are fixed by the first mounting bolt and the second mounting bolt respectively. The installation and disassembly are simple, thus realizing the effect of making it convenient for workers to replace the ring cutter and the cutting blade. Attached Figure Description

[0040] The present application will be further described in detail below with reference to Figures 1-5.
[0041] This application discloses an automotive wiring harness production and processing equipment.
[0042] Referring to Figure 1, an automotive wiring harness production and processing equipment includes a base 1, a workbench 2 is arranged above the base 1, a wire clamping assembly 5 is arranged on one side of the workbench 2, a cutting assembly 6 is arranged on the workbench 2, and a wire feeding assembly 3 is arranged on the side of the workbench 2 away from the wire clamping assembly 5.
[0043] The wire clamping assembly 5 moves toward the workbench 2 until it clamps and fixes the end of the wire harness. Then the wire clamping assembly 5 drives the wire harness to move. At this time, the wire release assembly 3 releases the wire harness on the coil, thereby pulling the wire harness to the required length. Then the wire harness is cut by the cutting assembly 6.
[0044] Referring to Figures 1 and 2, the wire feeding assembly 3 includes a column 31 and a rotating roller 32. The column 31 is arranged in a vertical direction and its bottom is fixedly connected to the base 1. The rotating roller 32 is arranged in a horizontal direction and one end of the rotating roller 32 is rotatably connected to the column 31. A fourth drive motor 311 for driving the rotating roller 32 to rotate is installed on the column 31.
[0045] Referring to Figure 2, the coil is sleeved on the rotating roller 32, and a wire harness is wound on the coil. A fixing sleeve 321 and a limiting sleeve 322 are respectively provided on both sides of the coil. The fixing sleeve 321 and the limiting sleeve 322 are both sleeved on the rotating roller 32. The fixing sleeve 321 is fixedly connected to the rotating roller 32, and the limiting sleeve 322 is threadedly connected to the rotating roller 32. The limiting sleeve 322 presses the coil and the fixing sleeve 321 together.
[0046] Referring to Figure 1, a fixing plate 26 is provided horizontally on the side of the workbench 2 away from the base 1. A support plate 27 is fixedly connected to one side of the fixing plate 26 and the upper surface of the workbench 2. A telescopic cylinder 261 is installed on the surface of the fixing plate 26 facing the workbench 2. A pressure block 2611 is fixedly connected to the end of the telescopic cylinder 261. The pressure block 2611 is used to press the wire harness. A pulley 28 is installed on the top of the workbench 2.
[0047] The third drive motor 25 starts, driving the rotating roller 32 to rotate. The rotating roller 32 drives the coil to rotate through the limiting sleeve 322 and the fixing sleeve 321, thereby releasing the wire harness. The worker picks up one end of the wire harness and pulls it to the surface of the workbench 2, passing the wire harness through the pulley 28 and aligning the end of the wire harness with the wire clamping assembly 5. At this time, the telescopic cylinder 261 starts, driving the pressure block 2611 to press the wire harness tightly. When the wire clamping assembly 5 pulls the wire harness, the telescopic cylinder 261 starts, driving the pressure block 2611 to release the wire harness, and at the same time, the third drive motor 25 starts to release the wire harness from the coil.
[0048] Referring to Figure 1, a movable seat 4 is vertically arranged on the side of the workbench 2 away from the wire feeding assembly 3. A collection groove 11 is opened on the surface of the base 1 facing the movable seat 4. The collection groove 11 is arranged between the workbench 2 and the movable seat 4. A collection box 12 is arranged in the collection groove 11. Two rollers 41 are installed at the bottom of the movable seat 4. The two rollers 41 are respectively arranged on both sides of the movable seat 4. The rollers 41 are adapted to the rolling of the base 1, and neither of the two rollers 41 is on the same horizontal line as the collection groove 11.
[0049] Referring to Figure 1, a travel screw 21 and a guide rod 22 are arranged horizontally between the movable seat 4 and the worktable 2. One end of the travel screw 21 is rotatably connected to the worktable 2. A first drive motor 23 for driving the travel screw 21 to rotate is installed on the side of the worktable 2 facing the wire feeding assembly 3. The end of the travel screw 21 away from the worktable 2 passes through the movable seat 4 and the two are threadedly connected.
[0050] Referring to Figures 1 and 3, the wire clamping assembly 5 includes a fixed base 51 and a first bidirectional lead screw 52. The fixed base 51 is arranged horizontally, and one side of the fixed base 51 is fixedly connected to the side wall of the movable base 4 facing the worktable 2. Two hanging plates 511 are arranged vertically on the side of the fixed base 51 facing the base 1. The tops of the two hanging plates 511 are fixedly connected to the fixed base 51. The two hanging plates 511 are arranged opposite to each other at both ends of the fixed base 51. The first bidirectional lead screw 52 is arranged horizontally between the two hanging plates 511. The two ends of the first bidirectional lead screw 52 are provided with two sections of threads with opposite directions of rotation. The two ends of the first bidirectional lead screw 52 are rotatably connected to the two hanging plates 511 respectively. A second drive motor 5111 for driving the first bidirectional lead screw 52 to rotate is installed on one of the hanging plates 511.
[0051] Referring to Figure 3, both ends of the first bidirectional lead screw 52 are threadedly connected to a first base 521. The two bases are respectively set on the two threads of the first bidirectional lead screw 52. A limiting rod 5112 is set horizontally between the two hanging plates 511. The two ends of the limiting rod 5112 are fixedly connected to the two hanging plates 511 respectively, and the limiting rod 5112 passes through the two first bases 521. The limiting rod 5112 and the two first bases 521 are slidably adapted. The wire clamping assembly 5 also includes a clamping rod 53. The number of clamping rods 53 is the same as the number of first bases 521 and corresponds one-to-one. The clamping rods 53 are fixedly connected to the first bases 521.
[0052] The first drive motor 23 starts and drives the travel screw 21 to rotate, thereby the travel screw 21 drives the moving seat 4 to move closer to the worktable 2 until the end of the wire harness is between the two clamping rods 53. Then the first drive motor 23 stops working. Then the second drive motor 5111 starts and drives the first bidirectional screw 52 to rotate, thereby the first bidirectional screw 52 drives the two first bases 521 to move towards each other along the limiting rod 5112. Then the first bases 521 drive the two clamping rods 53 to clamp the wire harness. At this time, the second drive motor 5111 stops working. After the wire harness is clamped, the first drive motor 23 starts and rotates in the opposite direction again, thereby the travel screw 21 pulls the wire harness to the required length through the moving seat 4 and the wire clamping assembly 5. Then the cutting assembly 6 cuts the wire harness. After the cutting is completed, the second drive motor 5111 starts and rotates in the opposite direction again, thereby the first bidirectional screw 52 drives the two first bases 521 to move away from each other. The cut wire harness falls into the collection box 12.
[0053] Referring to Figures 3 and 4, a ring-cutting seat 7 is provided on one side of the two clamping rods 53. The ring-cutting seat 7 is a hollow structure. A support rod 71 is fixedly connected between the ring-cutting seat 7 and the fixed seat 51 in the vertical direction. Multiple first tool holders 72 are provided inside the ring-cutting seat 7. The multiple first tool holders 72 are evenly spaced around the central axis of the ring-cutting seat 7. In this embodiment, four first tool holders 72 are provided. A ring-cutting rod 74 is fixedly connected to the side of the first tool holder 72 facing the inner wall of the ring-cutting seat 7. The ring-cutting rod 74 passes through the ring-cutting seat 7 and extends to the outside. The ring-cutting rod 74 and the ring-cutting seat 7 are slidably adapted to each other. A ring-cutting spring 75 is sleeved on the ring-cutting rod 74. The two ends of the ring-cutting spring 75 are fixedly connected to the first tool holder 72 and the ring-cutting seat 7, respectively.
[0054] Referring to Figure 4, the first tool holder 72 includes a first mounting base 721 and a first mounting bolt 722. The first mounting base 721 is fixedly connected to the circumferential cutting rod 74. A first mounting groove 7211 is provided on the side of the first mounting base 721 away from the circumferential cutting rod 74. A circumferential cutting blade 73 is installed in the first mounting groove 7211. The circumferential cutting blade 73 is arc-shaped, and four circumferential cutting blades 73 form a circle. There are two first mounting bolts 722. The opposite ends of the two first mounting bolts 722 extend into the first mounting groove 7211 and abut against the circumferential cutting blade 73. The first mounting bolts 722 are threadedly connected to the first mounting base 721.
[0055] Referring to Figures 3 and 4, a transmission assembly 8 is provided on one side of the fixed base 51. The transmission assembly 8 includes a trigger sleeve 81 and a trigger rod 82. The trigger sleeve 81 has a hollow structure and is fitted onto the annular cutting base 7 with a sliding fit between them. An inclined surface is annularly opened on the side of the trigger sleeve 81 near the annular cutting rod 74. A guide block 811 is fixed on the inner wall of the trigger sleeve 81. A guide groove 76 is opened on the outer wall of the annular cutting base 7 to slide and fit with the guide block 811. The annular cutting base 7 is fixed in the guide groove 76. A guide rod 77 is connected, which passes through the guide block 811 and is slidably adapted to the guide block 811. A reset spring 78 is sleeved on the guide rod 77. The two ends of the reset spring 78 are fixedly connected to the guide block 811 and the annular cut seat 7, respectively. The number of trigger rods 82 is the same as the number of the first base 521 and corresponds one-to-one. The trigger rods 82 are fixedly connected to the first base 521. An inclined surface is opened on the side of the trigger rod 82 facing the trigger sleeve 81. The inclined surface of the trigger rod 82 is used to press the trigger sleeve 81.
[0056] When the two first bases 521 move towards each other, the first base 521 presses the trigger sleeve 81 through the trigger rod 82. The trigger sleeve 81 moves closer to the circumferential cutting rod 74 under pressure. At this time, the return spring 78 is in a stretched state, thus the trigger sleeve 81 presses the circumferential cutting rod 74. The circumferential cutting rod 74 drives the circumferential cutting blade 73 to move closer to the wire harness through the first mounting seat 721. At this time, the circumferential cutting spring 75 is in a stretched state, thereby cutting off the outer sheath of the wire harness. When the two first bases 521 move away from each other, the first base 521 drives the trigger rod 82 away from the trigger sleeve 81. At this time, the return spring 78 releases its elastic force to drive the trigger sleeve 81 to reset. At the same time, the circumferential cutting spring 75 releases its elastic force to drive the circumferential cutting blade 73 to reset through the first mounting seat 721. During the movement of the trigger sleeve 81, the trigger sleeve 81 drives the guide block 811 to slide along the guide groove 76 and the guide rod 77.
[0057] Referring to Figures 1 and 5, a storage cavity 24 is provided on the surface of the worktable 2 facing the movable seat 4. Two second bases 9 are slidably connected in the storage cavity 24. A second tool holder 91 is provided on the side of the worktable 2 facing the movable seat 4. The number of second tool holders 91 is the same as that of the second bases 9 and they correspond one-to-one. The second tool holders 91 are fixedly connected to the second bases 9.
[0058] Referring to Figure 5, the second blade holder 91 includes a second mounting base 911 and a second mounting bolt 912. The second mounting base 911 is fixedly connected to the second base 9. The two second mounting bases 911 have second mounting grooves 9111 on their opposite sidewalls. The cutting assembly 6 includes a cutting blade 62. The number of cutting blades 62 is the same as the number of second mounting grooves 9111 and they correspond one-to-one. The cutting blades 62 are disposed in the second mounting grooves 9111. There are two second mounting bolts 912. The two second mounting bolts 912 are disposed opposite each other on both sides of the second mounting base 911. The opposite ends of the two second mounting bolts 912 extend into the second mounting grooves 9111 and abut against the cutting blades 62. The second mounting bolts 912 are threadedly connected to the second mounting base 911.
[0059] Referring to Figure 5, the cutting assembly 6 also includes a second bidirectional lead screw 61. The two ends of the second bidirectional lead screw 61 are provided with two sections of threads with opposite directions of rotation. The second bidirectional lead screw 61 is arranged horizontally in the receiving cavity 24. Both ends of the second bidirectional lead screw 61 are rotatably connected to the inner wall of the worktable 2 at the receiving cavity 24. The second bidirectional lead screw 61 passes through two second bases 9. The second bidirectional lead screw 61 is threadedly connected to the two second bases 9, and the two bases are respectively arranged on the two sections of threads. A third drive motor 25 for driving the bidirectional lead screw to rotate is installed on the side wall of one side of the worktable 2.
[0060] After the wire clamping assembly 5 pulls the wire harness to the required length, the third drive motor 25 starts and drives the second bidirectional lead screw 61 to rotate. The second bidirectional lead screw 61 drives the two second bases 9 to move towards each other, thereby the two second bases 9 drive the two second mounting seats 911 to move towards each other. As a result, the two cutting blades 62 cut the wire harness. Then the third drive motor 25 rotates in the opposite direction, thereby causing the two second bases 9 to move away from each other through the second bidirectional lead screw 61, thereby resetting the cutting blades 62.
[0061] The implementation principle of the automotive wire harness production and processing equipment in this application embodiment is as follows: The first drive motor 23 starts, driving the wire clamping assembly 5 towards the workbench 2 via the moving base 4, so that the clamping rods 53 are positioned on both sides of one end of the wire harness. Simultaneously, the wire harness passes through the ring-cutting seat 7. At this time, the second drive motor 5111 starts, clamping the wire harness with the two clamping rods 53. Simultaneously, the first base 521, through the transmission assembly 8, drives the ring-cutting rod 74 to drive the ring-cutting blade 73 to ring-cut the outer sheath of the wire harness end. Then, the first drive motor 23 starts rotating in the opposite direction, pulling the wire harness to the required length via the wire clamping assembly 5. At this time, the third drive motor 25 starts, driving the two cutting blades 62 to move closer together, thereby cutting the wire harness. Through the above structure, the cutting accuracy of the wire harness is improved.
[0062] This application also discloses a method for manufacturing and processing automotive wiring harnesses.
[0063] Includes the following steps:
