Description

Technical Field

[0001] This invention relates to the field of wire harness processing technology, and more specifically to a high-speed wire harness core conductor shaping device. Background Technology

[0002] A wire harness is composed of several wires assembled through a specific process. These wires are usually wrapped in insulating material to ensure their safety and reliability. The main function of a wire harness is to transmit electrical energy or signals, playing a crucial role in various electronic devices, automobiles, and mechanical equipment. Wire harnesses can be classified according to their structure into full-utilization wire harnesses, partial-utilization wire harnesses, and link systems; according to their service mode, they can be classified into loss-based wire harnesses and waiting-based wire harnesses (see random service systems); and according to the number of load sources they serve, they can be classified into unlimited load source wire harnesses and finite load source wire harnesses.

[0003] High-speed wire harnesses are one of the most common types of wire harnesses and are also special wire harnesses adapted to high-frequency signals (usually ≥1GHz) and high-bandwidth transmission requirements. They are primarily used to transmit high-speed data, control signals, or high-frequency energy and are widely used in automotive, communication, industrial automation, aerospace and other fields. Their core requirements are low loss, anti-interference, and strong signal integrity.

[0004] During wire harness manufacturing, the core conductors need to be shaped. A clamping mechanism is used to hold and secure the wire harness during this process. Core conductor shaping is a critical step in wire harness manufacturing. Its core objectives are to correct conductor stranding deformation, ensure a regular conductor cross-section, improve the reliability of crimping / soldering with terminals / connectors, and avoid damaging the conductor copper wires (tinned copper, bare copper, etc.), ensuring the stability of signal transmission or power conduction. This process is suitable for various types of wire harnesses (including high-speed wire harnesses, low-voltage power lines, and signal wire harnesses). Especially for high-frequency, high-speed wire harnesses, a regular conductor shape can reduce signal reflection and loss, improving transmission performance.

[0005] Chinese patent application CN118920226A discloses a wire harness crimping machine, specifically comprising: a base block; a top plate positioned directly above the base block, with the top plate and base block fixedly connected by two symmetrically arranged side support plates; a set of electric cylinders fixedly mounted on the top surface of the top plate; an upper pressing block positioned directly below the top plate, with the piston end of the electric cylinders penetrating the top plate and fixedly connected to the upper pressing block; and a lower mating block fixedly mounted on the top surface of the base block relative to the upper pressing block; the top of the lower mating block... A lower pressing module is fixedly installed on the upper pressing block, and an upper pressing module that presses against the lower pressing module is fixedly installed on the bottom surface of the upper pressing block. The front face of the lower mating block has two symmetrically arranged reset and storage slots, and each of the two reset and storage slots has a limiting insertion hole penetrating the rear face of the lower mating block. A protective cover is provided in front of the upper pressing block and the lower mating block, and two limiting pins are fixedly connected symmetrically on the lower side of the rear face of the protective cover. The two limiting pins are respectively inserted into the two limiting insertion holes, and the protective cover covers the area. The crimping gap between the lower and upper crimping modules is located here; two spring-loaded reset components are symmetrically fixedly connected to the lower rear side of the protective cover plate, and each reset component is sleeved around one of the two limiting posts. The rear ends of the two reset components are fixedly connected to the rear sides of the inner ends of two reset receiving slots; when the reset components are extended, the rear end of the protective cover plate does not contact the front end of the lower mating block; the front end of the protective cover plate has a crimping fit opening that penetrates its rear end, and the crimping fit opening is located between the lower and upper crimping modules. The positions of the crimping gaps correspond to each other; an extension plate is fixedly installed on both the front and rear faces of the base block, and the top faces of the two extension plates are symmetrically arranged with two insertion holes penetrating their bottom faces; a control box is fixedly installed on the top face of the top plate, and the electric cylinder is electrically connected to the control box; an embedded groove is opened in the center of the front face of the lower mating block, and a set of crimping control switches is fixedly installed on the rear side of the inner end of the embedded groove. The crimping control switches are tactile switches, with the button end of the crimping control switches facing forward, and the crimping control switches are electrically connected to the control box.

[0006] When crimping wire harnesses, the operator first inserts the locking drive mating block into the locking drive mating slot and squeezes the locking torsion member to rotate it. This simultaneously drives the pressure stud to rotate to the right along the threaded through hole until the right end of the pressure stud presses against the button of the power switch, thus connecting the power. The operator holds the wire harness to be crimped and inserts it into the crimping opening. Because the crimping opening corresponds to the crimping gap between the lower and upper crimping modules, the wire harness end is positioned between the upper and lower crimping modules. Simultaneously, the operator's hand gripping the wire harness presses against the protective cover, causing it to move backward. As the protective cover moves backward, the two limit pins slide backward along the limit pin holes, compressing the reset member. At this time, the protective cover also presses against the button. The crimping control switch sends a feedback signal to the control box, which then controls the extension of the electric cylinder piston. This extension causes the upper pressing block and upper crimping module to move downwards, allowing the upper and lower crimping modules to crimp the wire harness placed between them. Once the crimping is complete, the operator simply needs to remove pressure from the protective cover. Without the operator's hand pressing down, the compressed reset component quickly springs back, automatically pushing the protective cover back to its original position. At this point, without pressure from the protective cover, the crimping control switch button will also automatically reset. When there is no signal feedback from the crimping control switch, the control box will retract the electric cylinder piston, allowing the operator to remove the crimped wire harness for the next crimping operation.

[0007] In the aforementioned technology, during the wire harness crimping process, the operator needs to hold the wire harness to be crimped, align the end of the wire harness with the crimping opening, and insert it between the upper and lower crimping modules. Since the exposed metal wires at the end of the wire harness are at risk of unraveling, the unraveling wires may cause the metal wires to not be evenly distributed in the terminal during crimping, affecting the stability of the electrical connection. Therefore, the operator needs to observe the exposed metal wires at the end of the wire harness before crimping and tidy up any unraveling wires before inserting them. This manual tidying and inserting of the wire harness ends one by one is a repetitive and time-consuming process, which also increases the possibility of operational errors and makes it difficult to maintain stable crimping quality. Summary of the Invention

[0008] This invention provides a high-speed wire harness core conductor shaping device, aiming to solve the technical problem in the existing wire harness crimping machine process. During wire harness crimping, the operator needs to hold the wire harness to be crimped, align the end of the wire harness with the crimping opening, and insert it between the upper and lower crimping modules. Because the exposed metal wires at the end of the wire harness are at risk of unraveling, this unraveling may cause the metal wires to be unevenly distributed within the terminal during crimping, affecting the stability of the electrical connection. Therefore, the operator needs to observe the exposed metal wires at the end of the wire harness before crimping and tidy up any unraveling wires before insertion. This manual tidying and insertion of the wire harness ends one by one is a repetitive and time-consuming process, increasing the possibility of operational errors and making it difficult to maintain stable crimping quality.

[0009] This invention discloses a high-speed wire harness conductor shaping device, comprising a frame and a shaping mechanism. The shaping mechanism includes a clamping assembly and a shaping assembly mounted on the frame. The clamping assembly includes two clamping plates arranged opposite each other in the vertical direction and two power members for driving the two clamping plates to move respectively. The clamping plates are slidably fitted onto the frame in the vertical direction. When the two power members are working, they respectively drive the two clamping plates to slide in the vertical direction, thereby fixing, clamping, and unlocking the wire harness. The shaping assembly includes two shaping plates arranged opposite each other in the vertical direction and two driving members for driving the two shaping plates to move respectively. The shaping plates are slidably fitted onto the frame in the vertical direction. The two shaping plates are arranged opposite each other in the vertical direction and have multiple shaping grooves. The shaping grooves of the two shaping plates are staggered in the vertical direction. When the two driving members are working, they respectively drive the two shaping plates to move closer to each other, thereby shaping the wire harness.

[0010] Beneficial effects: By setting up clamping and shaping components, when wire harnesses need to be shaped, the wire harness is first placed on the frame and conveyed on the frame. When the wire harness reaches the bottom of the shaping mechanism, it is shaped. During the shaping process, two power components work, driving two clamping plates to slide vertically. The two clamping plates move closer together and fix the wire harness. At the same time, two drive components work, driving two shaping plates to slide. The two shaping plates move closer together and can shape the wire harness, thereby tidying up the wire harness ends and maintaining stable crimping quality. After the wire harness ends are shaped, the two power components work, driving the two clamping plates to slide vertically. The two clamping plates move away from each other and no longer fix the wire harness. At the same time, the two drive components work, driving the two shaping plates to slide and move away from each other.

[0011] Preferably, the frame is equipped with a conveyor belt and positioning fixtures. The conveyor belt extends front to back and forms a feeding station and a crimping station from back to front. Multiple positioning fixtures are arranged on the conveyor belt along its length. Each positioning fixture includes a reference jaw and a movable jaw distributed left and right to hold the wire harness. A feeding mechanism is arranged above the feeding station. The feeding mechanism includes a hopper containing the wire harness and a pusher installed above the hopper to push the wire harness in the hopper into the positioning fixtures. A crimping mechanism is arranged beside the crimping station and is used to gather and shape the exposed metal wires at the ends of the wire harness.

[0012] Beneficial effects: After the conveyor belt transports the wire harness to the crimping station, the clamping pliers can clamp and fix the ends of the wire harness, thereby assisting the straightening pliers in gathering and shaping the exposed metal wires at the ends of the wire harness, ensuring that the exposed metal wires at the ends of the wire harness are neatly arranged and do not scatter. Then, under the limitation of the straightening pliers on the exposed metal wires at the ends of the wire harness, the clamping pliers can place the shaped ends of the wire harness in the crimping position, realizing automatic feeding, automatic positioning and automatic crimping of the wire harness. Furthermore, through the cooperation between the straightening pliers and the clamping pliers, the exposed metal wires at the ends of the wire harness are automatically straightened, ensuring that the metal wires are evenly distributed in the terminals during crimping, ensuring the stability of the electrical connection, and improving the consistency of crimping efficiency, crimping accuracy and crimping quality.

[0013] Preferably, the crimping mechanism includes a crimping bracket, a crimping die disposed on the crimping bracket and having a crimping position formed on its upper surface, crimping heads spaced above the crimping die for crimping wire harnesses, and two operating clamps respectively mounted on the crimping bracket and positioned to move left and right relative to the crimping position. The operating clamps away from the crimping position are clamping clamps used to clamp and transfer the wire harness, while the operating clamps near the crimping position are tidying clamps. The tidying clamps have tidying holes for accommodating the wire harness, and when the tidying clamps move left and right, the tidying holes can gather and shape the exposed metal wires at the ends of the wire harness.

[0014] Preferably, the conveyor belt has movable slots that correspond one-to-one with each positioning clamp and extend to the left and right, and the movable claws are movably assembled in the movable slots;

[0015] The frame is also equipped with a posture adjustment table located between the feeding station and the crimping station. The posture adjustment table has a guide slope for pushing the movable claw to move along the movable slot. When the movable claw moves along the movable slot, it can straighten the wire harness left and right.

[0016] Beneficial effects: Used to adjust the orientation of the wire harness, ensuring that the wire harness is arranged in a predetermined direction, so as to facilitate accurate subsequent crimping operations.

[0017] Preferably, the reference jaw is mounted on the conveyor belt and moves up and down. The reference jaw includes a clamping part for clamping the wire harness, a connecting rod passing through the conveyor belt from the clamping part, an extension cap fixed to the end of the connecting rod away from the clamping part, and a clamping spring connected between the extension cap and the conveyor belt. The clamping spring is used to apply an elastic force to the extension cap so that the extension cap approaches the conveyor belt and drives the clamping part to extend from the surface of the conveyor belt, thereby clamping the wire harness.

[0018] Preferably, the conveyor belt is U-shaped and has an upper conveying surface and a lower conveying surface. The frame is also provided with a reset platform located at the lower conveying surface. The reset platform has a first reset slope for pushing the protruding cap away from the conveyor belt. When the protruding cap moves away from the conveyor belt, it can drive the clamping part to retract from the conveyor belt surface, thereby releasing the wire harness.

[0019] Preferably, the wire harness crimping machine also includes multiple positioning bosses spaced apart along the length of the conveyor belt, with a left-right extending positioning groove formed between two adjacent positioning bosses for installing positioning clamps.

[0020] Beneficial effects: It helps guide individual wire harnesses into the positioning fixture, ensuring orderly feeding of wire harnesses.

[0021] Preferably, the pusher includes a pusher plate that is mounted in the hopper and moves along the height direction of the hopper, and a pusher drive component that drives the pusher plate to move along the height direction of the hopper. The lower side of the hopper facing the crimping mechanism has a discharge port. The height of the discharge port is adapted to the height of the wire harness, and the width of the discharge port is less than the length of the wire harness.

[0022] Preferably, the feeding mechanism further includes a feeding bracket fixed on the frame, an active rack connected to the output end of the pushing drive component, a hopper mounted on the feeding bracket along the length of the conveyor belt, a vibrating rack on the hopper that can cooperate with the active rack to drive the hopper to move along the length of the conveyor belt under the push of the active rack, and a vibrating spring between the hopper and the feeding bracket.

[0023] Beneficial effects: During the process of the pusher plate being pushed downwards by the pusher drive, the active rack drives the hopper to move slightly along the length of the conveyor belt by pushing the vibrating rack. At the same time, it moves in the opposite direction to reset under the action of the vibrating spring. This repeated action can realize the vibration feeding of the hopper, thereby helping to loosen the wire harness that may be accumulated or stuck in the hopper, making it easier to flow and be pushed smoothly onto the positioning fixture, thus improving the discharge and feeding efficiency.

[0024] Preferably, the crimping mechanism further includes an operating drive component that corresponds to each operating clamp to drive the operating clamp to move left and right. Each operating clamp includes two clamp bodies arranged opposite each other and a jaw located at the lower end of each clamp body. The output end of the operating drive component is provided with a drive plate, and the drive plate is provided with two connecting shafts that are respectively connected to the upper end of each clamp body.

Detailed Implementation

[0041] Embodiments of the present invention are described in detail below, with examples of the embodiments illustrated in the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain the present invention, and should not be construed as limiting the present invention.

[0042] Reference Figures 1-15 This invention discloses a high-speed wire harness conductor shaping device, comprising a frame 10 and a shaping mechanism 1 disposed on the frame 10. The shaping mechanism 1 includes a clamping component 2 and a shaping component 3 disposed on the frame 10. The clamping component 2 is used to clamp the wire harness, and the shaping component 3 is used to shape the wire harness. When the wire harness needs to be shaped, it is first placed on the frame 10 and conveyed on the frame 10. When it is conveyed to the shaping mechanism 1, the clamping component 2 clamps the wire harness, and the shaping component 3 shapes the wire harness.

[0043] Reference Figures 1-7The clamping assembly 2 includes two clamping plates 21 arranged opposite each other in the vertical direction and two power components for driving the two clamping plates 21 to move respectively. One end of each clamping plate 21 near the wire harness has an arc-shaped groove adapted to the wire harness 90. The clamping plates 21 slide vertically onto the frame 10. The power components can be hydraulic cylinders (not shown in the figure) and power frames fixedly connected to the clamping plates 21. When the two power components are working, they respectively drive the two clamping plates 21 to slide vertically, and fix and unlock the wire harness 90. The shaping assembly 3 includes two clamping plates arranged vertically... Two shaping plates 31 are arranged facing each other upwards, and two driving members are used to drive the two shaping plates 31 to move respectively. The shaping plates 31 are slidably fitted on the frame 10 in the vertical direction. The two shaping plates 31 are arranged facing each other in the vertical direction. Multiple shaping grooves are opened on the shaping plates 31. The shaping grooves of the two shaping plates 31 are staggered in the vertical direction. The driving members can be hydraulic cylinders (not shown in the figure) and driving frames fixedly connected to the shaping plates 31. When the two driving members work, they drive the two shaping plates 31 to move closer to each other, which can shape the wire harness 90.

[0044] Reference Figures 1-7 The frame 10 is provided with an adjustment device 4. The adjustment device 4 includes a sliding component 41 for driving the shaping mechanism 1 to slide along the length direction of the frame 10 and a sliding component 42 for driving the shaping mechanism 1 and the sliding component 41 to slide along the conveying direction of the wire harness 90. The position of the shaping mechanism 1 is adjusted by the sliding component 41 and the sliding component 42 to adapt to the wire harness 90.

[0045] Reference Figures 8-15 The system includes a conveyor belt 20, a positioning clamp 30, a positioning boss 40, a feeding mechanism 50, a pressing mechanism 60, a posture adjustment table 70, and a reset table 80. The conveyor belt 20, feeding mechanism 50, pressing mechanism 60, posture adjustment table 70, and reset table 80 are respectively mounted on the frame 10, while the positioning clamp 30 and positioning boss 40 are respectively mounted on the conveyor belt 20.

[0046] Reference Figure 8 and Figure 9 The conveyor belt 20 is shaped like a U-shape and has an upper conveying surface and a lower conveying surface that extend forward and backward. Along the length of the conveyor belt 20, there are sequentially formed loading station 210, adjustment station 220, and crimping station 230 on the upper conveying surface, and unloading station 240 on the lower conveying surface, so as to transport the wire harness 90 from one station to another, realizing continuous processing and automated production of the wire harness 90.

[0047] Multiple positioning bosses 40 are fixed at intervals along the length of the conveyor belt 20. A left-right extending positioning groove is formed between two adjacent positioning bosses 40 for installing positioning clamps 30 and for guiding individual wire harnesses 90 into the positioning clamps 30, ensuring orderly feeding of the wire harnesses 90. The conveyor belt 20 has left-right extending movable slots 250 at each positioning groove.

[0048] Reference Figure 10 and Figure 11 Each positioning fixture 30 includes a reference jaw 310 and a movable jaw 320 distributed on the left and right to hold the wire harness 90. The positioning fixture 30 is used to fix the position of the wire harness 90 and ensure the precise positioning of the wire harness 90 during the processing, so as to facilitate the subsequent crimping operation.

[0049] The reference jaw 310 is mounted vertically on the conveyor belt 20. The reference jaw 310 includes a clamping portion 311 for clamping the wire harness 90, a connecting rod 312 passing through the clamping portion 311 and extending through the conveyor belt 20, an extension cap 313 fixed to the end of the connecting rod 312 away from the clamping portion 311, and a clamping spring 314 connecting the extension cap 313 and the conveyor belt 20. The clamping spring 314 applies an elastic force to the extension cap 313, causing the extension cap 313 to approach the conveyor belt 20 and drive the clamping portion 311 to extend from the surface of the conveyor belt 20, thereby clamping the wire harness 90. The reference jaw 310 clamps the wire harness 90, ensuring that the wire harness 90 will not easily slip or fall off during conveying, and provides a fixed positioning reference point for the wire harness 90, maintaining the relative stability of the wire harness 90's position.

[0050] The movable claw 320 is movably mounted within the movable slot 250. The force exerted by the movable claw 320 on the wire harness 90 is less than that of the reference claw 310, so that when the movable claw 320 moves along the movable slot 250, it can smoothly cooperate with the reference claw 310 to adjust the posture of the wire harness 90, thereby straightening the wire harness 90 left and right.

[0051] It should be noted that the conveyor roller used to drive the conveyor belt 20 is provided with a groove for the positioning clamp 30 to pass through, so as to avoid the positioning clamp 30 from getting stuck with the conveyor roller during operation.

[0052] Reference Figures 10-12 The feeding mechanism 50 is located above the feeding station 210. The feeding mechanism 50 includes a hopper 510, a pusher 520, a feeding bracket 530, an active rack 540, a vibrating rack 550, a vibrating spring 560, and a locking plate 570.

[0053] The feeding bracket 530 is fixed to the frame 10. The hopper 510 is mounted on the feeding bracket 530 along the length of the conveyor belt 20, and contains the wire harness 90 to be fed. The lower side of the hopper 510 facing the crimping station 230 has a discharge port 511. The height of the discharge port 511 is adapted to the height of the wire harness 90, ensuring that only a single wire harness 90 can pass through the discharge port 511 at any given height. The width of the discharge port 511 is less than the length of the wire harness 90. Because the wire harness 90 has a certain degree of flexibility, it can bend to pass through the discharge port 511, thereby preventing multiple wire harnesses 90 from crossing and tangling while passing through the discharge port 511 at the same time. This ensures that only one wire harness 90 is supplied at a time, guaranteeing that the wire harnesses 90 are fed neatly and orderly.

[0054] The pusher 520 is mounted on the feeding bracket 530 and located above the hopper 510. It is used to push the wire harness 90 in the hopper 510 into the positioning fixture 30. The pusher 520 includes a pusher plate 521 mounted in the hopper 510 and moving along the height direction of the hopper 510, and a pusher drive 522 that drives the pusher plate 521 to move along the height direction of the hopper 510. The pusher drive 522 is a hydraulic cylinder. When the pusher drive 522 drives the pusher plate 521 to move downward, the pusher plate 521 can push the wire harness 90 in the hopper 510 downward, so that the wire harness 90 enters the reference jaw 310 and the movable jaw 320, is clamped by the positioning fixture 30, and then moves with the conveyor belt 20 through the discharge port 511 and enters the adjustment station 220.

[0055] It should be noted that the distance between the reference jaw 310 and the movable jaw 320 at the loading station 210 is relatively close to ensure that the wiring harness 90 entering the reference jaw 310 and the movable jaw 320 is the same wiring harness 90, thereby improving the accuracy of the loading process.

[0056] The locking plate 570 is fixed on the feeding bracket 530 and located below the conveyor belt 20. It is used to restrict the downward movement of the extension cap 313 of the reference claw 310 when the reference claw 310 moves to the hopper 510, that is, above the locking plate 570, so as to prevent the reference claw 310 from falling off downward when the pusher 520 pushes the material downward, thereby ensuring that the reference claw 310 stably receives and clamps the wire harness 90.

[0057] The active rack 540 is connected to the output end of the pusher drive 522. The vibrating rack 550 is fixed on the hopper 510 and can cooperate with the active rack 540 to drive the hopper 510 to move along the length of the conveyor belt 20 under the push of the active rack 540. A vibrating spring 560 is provided between the hopper 510 and the feeding bracket 530. During the process of the pusher drive 522 driving the pusher plate 521 to push the wire harness 90 downward, the active rack 540 drives the hopper 510 to move slightly along the length of the conveyor belt 20 by pushing the vibrating rack 550. At the same time, under the action of the vibrating spring 560, it moves in the opposite direction to reset. This repeated movement can realize the vibration feeding of the hopper 510, thereby helping to loosen the wire harness 90 that may be accumulated or stuck in the hopper 510, making it easier to flow and be pushed smoothly onto the positioning fixture 30, thus improving the discharge and feeding efficiency.

[0058] In this embodiment, the conveyor belt 20 located at the loading station 210 is inclined upward from the loading station 210 toward the pressing station 230. The inclined conveyor belt 20 can help separate the wire harness 90 that is not held by the positioning fixture 30, reducing the accumulation and blockage of the wire harness 90 at the discharge port 511.

[0059] Reference Figure 9 , Figure 12 and Figure 13 An attitude adjustment table 70 is positioned at the adjustment station 220, between the upper and lower conveying surfaces of the conveyor belt 20. The upper surface of the attitude adjustment table 70 has a guide ramp 710 for pushing the movable claw 320 along the movable slot 250. After the conveyor belt 20 transports the wire harness 90 to the adjustment station 220, the guide ramp 710 pushes the movable claw 320 along the movable slot 250, causing the movable claw 320 to move away from the reference claw 310 and straighten the wire harness 90 left and right, thereby adjusting the attitude of the wire harness 90 and ensuring that the wire harness 90 is aligned in a predetermined direction for precise subsequent crimping operations.

[0060] In this embodiment, the lower surface of the attitude adjustment table 70 is also provided with a second reset slope. The second reset slope is used to push the movable claw 320 along the movable slot 250 to approach the reference claw 310 after the positioning fixture 30 passes the unloading station 240, so that the movable claw 320 is reset.

[0061] Reference Figure 13 , Figure 14 and Figure 15 There are two crimping mechanisms 60, which are symmetrically arranged on the left and right sides of the crimping station 230. Each crimping mechanism 60 includes a crimping bracket 610, a crimping mold 620, a crimping connector 630, an operating clamp 640, an operating drive component 650, a transmission sleeve 660, and a crimping drive component 670.

[0062] The crimping bracket 610 is fixed to the frame 10. The crimping die 620 is mounted on the crimping bracket 610, and its upper surface forms a crimping position. The crimp connector 630 is disposed on the crimping bracket 610 and spaced above the crimping die 620. The crimp connector 630 is used to crimp the wire harness 90. The crimping drive 670 is a hydraulic cylinder and is mounted on the crimping bracket 610. The output end of the crimping drive 670 is connected to the crimp connector 630 to drive the crimp connector 630 to move up and down.

[0063] There are two operating clamps 640, which are mounted on the crimping bracket 610 and moved left and right respectively, facing the crimping position. Each operating clamp 640 includes two opposing clamp bodies 643 and jaws 644 located at the lower end of each clamp body 643. The operating clamp 640 away from the crimping position is a clamping clamp 641. When the two jaws 644 of the clamping clamp 641 are closed, it can form a firm clamping force on the wire harness 90, used to fix and move the wire harness 90. The operating clamp 640 closer to the crimping position is a tidying clamp 642. When the two jaws 644 of the tidying clamp 642 are closed, it can form a tidying hole for accommodating the wire harness 90. When the tidying clamp 642 moves left and right, the tidying hole can gather and shape the exposed metal wires at the end of the wire harness 90.

[0064] Each operating drive unit 650 corresponds to one of the operating clamps 640, and is used to drive the operating clamps 640 to open, close, and move left and right. The operating drive unit 650 is a hydraulic cylinder and is mounted on the crimping bracket 610. The output end of the operating drive unit 650 is provided with a drive plate 651, on which two connecting shafts 652 are rotatably mounted, respectively fixedly connected to the upper end of each clamp body 643. Each transmission sleeve 660 corresponds to one of the connecting shafts 652 and is fixed on the crimping bracket 610. The inner sidewall of the transmission sleeve 660 is provided with a transmission guide groove 661, through which the connecting shafts 652 pass and are provided with a transmission guide block that moves in cooperation with the transmission guide groove 661. The transmission guide groove 661 includes a straight groove 662 that extends left and right near the crimping position and a spiral groove 663 that is away from the crimping position and communicates with the straight groove 662.

[0065] It should be noted that when the operating drive unit 650 drives the drive plate 651 to approach the pressing position, the transmission guide block of the connecting shaft 652, pushed by the spiral groove 663, drives the connecting shaft 652 to rotate, thereby causing the two jaws 643 of the operating clamp 640 to move closer to each other and the jaws 644 to close. When the operating drive unit 650 continues to drive the drive plate 651 to move, the transmission guide block of the connecting shaft 652 moves within the straight groove 662, causing the operating clamp 640, which remains in a closed state, to approach the pressing position.

[0066] Thus, after the conveyor belt 20 transports the wire harness 90 to the crimping station 230, the crimping mechanism 60 on one side first performs the crimping operation. First, the operating drive unit 650 corresponding to the clamping clamp 641 drives the clamping clamp 641 to close, so that the clamping clamp 641 clamps the end of the wire harness 90 and fixes the wire harness 90.

[0067] Next, the operating drive unit 650 corresponding to the sorting clamp 642 drives the sorting clamp 642 to close, so that the sorting hole of the sorting clamp 642 can accommodate the exposed metal wire at the end of the wire harness 90. The operating drive unit 650 corresponding to the sorting clamp 642 continues to work and drives the operating clamp 640, which is kept in the closed state, to approach the crimping position. Together with the clamping clamp 641, the exposed metal wire at the end of the wire harness 90 is gathered and shaped to ensure that the exposed metal wire at the end of the wire harness 90 is neatly arranged and does not spread out.

[0068] Subsequently, the operating drive unit 650 corresponding to the clamping clamp 641 continues to operate, driving the clamping clamp 641 holding the end of the wire harness 90 closer to the crimping position. This coordinates with the straightening clamp 642 to limit the exposed metal wires at the end of the wire harness 90, placing the shaped end of the wire harness 90 in the crimping position and performing the crimping operation. After crimping is completed, the two operating drive units 650 respectively drive the drive plate 651 to move in the opposite direction and reset, so as to move the wire harness 90 back to its original position and release the wire harness 90.

[0069] After the crimping mechanism 60 on this side has finished its work, when it is necessary to crimp the other end of the wire harness 90, the crimping mechanism 60 on the other side will perform the crimping work and repeat the above steps, which will not be described in detail here.

[0070] Reference Figure 12 and Figure 13 A reset table 80 is located at the unloading station 240. The reset table 80 has a first reset ramp 810 for pushing the extension cap 313 away from the conveyor belt 20. During the process of the conveyor belt 20 conveying the wire harness 90 from the crimping station 230 to the unloading station 240, the wire harness 90 enters the lower conveying surface of the conveyor belt 20 from the upper conveying surface. Under the action of gravity, the wire harness 90 is disengaged from the movable claw 320. Then, when the conveyor belt 20 conveys the wire harness 90 to the unloading station 240, the first reset ramp 810 pushes the extension cap 313 away from the conveyor belt 20. The extension cap 313 drives the clamping part 311 to retract from the belt surface of the conveyor belt 20, thereby releasing the wire harness 90 to complete the automatic unloading of the wire harness 90.

[0071] In other embodiments, the pusher drive 522, the crimping drive 670, and the operation drive 650 may also be cylinders or electric push rods.

[0072] Thus, a conveyor belt 20, a positioning clamp 30, a feeding mechanism 50, and a crimping mechanism 60 are installed on the frame 10. The pusher 520 in the feeding mechanism 50 can push the wire harnesses 90 to be fed in the hopper 510 onto the positioning clamp 30 on the conveyor belt 20, so as to feed, position, and convey the wire harnesses 90 one by one. After the conveyor belt 20 conveys the wire harnesses 90 to the crimping station 230, the clamping pliers 641 can clamp and fix the ends of the wire harnesses 90, thereby assisting the sorting pliers 642 in gathering the exposed metal wires at the ends of the wire harnesses 90. The wire harness 90 is shaped to ensure that the exposed metal wires at the end are neatly arranged and do not scatter. Then, the clamping pliers 641, under the constraint of the straightening pliers 642 on the exposed metal wires at the end of the wire harness 90, places the shaped end of the wire harness 90 in the crimping position. This realizes automatic feeding, automatic positioning and automatic crimping of the wire harness 90. Furthermore, through the cooperation between the straightening pliers 642 and the clamping pliers 641, the exposed metal wires at the end of the wire harness 90 are automatically straightened. Then, the wire harness 90 enters the shaping mechanism 1 for further shaping.

Those skilled in the art can make changes, modifications, substitutions and variations to the above embodiments within the scope of the present invention.
