Description

Technical Field

[0001] This invention relates to the technical field of automated wire harness processing equipment, specifically to an integrated system for intelligent sorting and bundling of multi-core wire harnesses. Background Technology

[0002] In aerospace, automotive electronics, and industrial control fields, the production and assembly of multi-core wire harnesses is a crucial step. After the wire harness is cut and stripped, the scattered core wires of different colors or codes are usually arranged in a specific order according to the circuit diagram, such as a color spectrum, and bundled together to facilitate subsequent terminal crimping or connector assembly.

[0003] Currently, this process mainly relies on manual operation. Workers need to select specific colored wires one by one from the scattered wire bundles, insert them into the cable management clamps in the order required by the process card, and finally bundle them by hand. This traditional method has many drawbacks: 1. Inefficient: Manual sorting is time-consuming and labor-intensive, which severely limits the production cycle.

[0004] 2. High error rate: Long-term repetitive visual work can easily lead to visual fatigue, and quality problems such as incorrect or missing lines are very likely to occur, and the rework cost is high.

[0005] 3. Poor consistency: It is difficult to maintain uniformity in the strength and position of manual bundling, which affects the standardization of finished wire harnesses.

[0006] Although there are some semi-automatic wiring devices, most of them cannot effectively solve the problem of seamless connection between the front-end "separation of scattered wire harnesses" and the back-end "intelligent identification and sorting". Therefore, there is an urgent need to develop an integrated intelligent sorting and bundling system for multi-core wire harnesses that integrates feeding, separation, identification, sorting and bundling. Summary of the Invention

[0007] To address the problems existing in the prior art, this invention provides an integrated intelligent sorting and bundling system for multi-core wire harnesses, which solves the problems of low efficiency, error-proneness, and low automation in manual sorting and sorting in the prior art.

[0008] To achieve the above objectives, the present invention employs an integrated intelligent sorting and bundling system for multi-core wire harnesses, comprising a frame and the following components mounted on the frame: A scattered wire harness feeding unit is disposed at one end of the frame; A single-wire separation unit is disposed adjacent to the output side of the scattered wire harness feeding unit; A movable comb sorting unit is disposed downstream of the single wire separation unit along the wire harness processing direction. The movable comb sorting unit is used to receive and temporarily store wire harnesses in a predetermined order. A transfer robot is positioned across the single-line separation unit, the vision recognition unit, and the mobile comb sorting unit, and the travel range of the transfer robot covers the working areas of the single-line separation unit, the vision recognition unit, and the mobile comb sorting unit. A visual recognition unit is fixedly installed below or to the side of the gripping and moving path of the transfer robot. An automatic strapping unit is located at one end of a movable comb-type sorting unit.

The upper surface of the first sliding comb tooth rack is provided with a plurality of first U-shaped sorting grooves perpendicular to the wire harness axis along the length direction.

[0011] As a further optimization of the above solution, the movable comb tooth sorting unit includes a second comb tooth mounting base plate and a second sliding comb tooth rack. The second comb tooth mounting base plate is fixed on the frame, and the second sliding comb tooth rack is slidably engaged on the guide rail of the second comb tooth mounting base plate and extends in a direction perpendicular to the wire harness axis. The upper surface of the second sliding comb tooth rack is provided with a plurality of second U-shaped sorting grooves parallel to the wire harness axis along the length direction.

[0012] As a further optimization of the above scheme, elastic retaining plates are fixedly provided on both sides of the groove opening of the second U-shaped sorting groove, and the free ends of the elastic retaining plates extend toward the center of the groove opening to form a contracting opening.

[0013] As a further optimization of the above solution, the movable comb sorting unit also includes a drive screw mounted on the second comb mounting base plate. The drive screw is threadedly engaged with the second sliding comb rack, and a drive component is connected to the input end of the drive screw.

[0014] As a further optimization of the above solution, the driving component is a drive motor.

[0015] As a further optimization of the above solution, the visual recognition unit includes a ring light source and an industrial camera. The optical axis of the lens of the industrial camera is perpendicular to the area through which the wire passes below the transfer robot, and the ring light source is coaxially sleeved on the outer periphery of the lens of the industrial camera.

[0016] As a further optimization of the above solution, the system also includes a clustering and pressing mechanism, which is set at the workstation between the movable comb sorting unit and the automatic bundling unit. The clustering and pressing mechanism includes a pair of arc-shaped clamps arranged vertically opposite each other, and the arc-shaped clamps can perform relative closing motion.

[0017] As a further optimization of the above solution, the concave arc surface of the arc-shaped clamp is covered with a polished chrome-plated layer.

[0024] To make the objectives, technical solutions, and advantages of this invention clearer, the invention will be further described in detail below with reference to the accompanying drawings and embodiments. However, it should be understood that the specific embodiments described herein are merely illustrative and are not intended to limit the scope of the invention.

[0025] It should be noted that when an element is referred to as "set on" or "provided with" another element, it can be directly on the other element or there may be an intermediate element. When an element is referred to as "connected to" or "connected to" another element, it can be directly connected to the other element or there may be an intermediate element at the same time. "Fixed connection" means fixed connection. There are many ways of fixed connection, which are not within the scope of protection of this document. The terms "vertical", "horizontal", "left", "right" and similar expressions used in this document are only for illustrative purposes and do not represent the only implementation method.

[0026] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention pertains. The terminology used in the specification herein is for the purpose of describing particular embodiments only and is not intended to limit the invention. The term "and / or" as used herein includes any and all combinations of one or more of the associated listed items. like Figure 1-7 As shown, a multi-core wire harness intelligent sorting and bundling integrated system includes a frame 1 and a scattered wire harness feeding unit 2, a single wire separation unit 3, a mobile comb sorting unit 4, a transfer robot 5, a vision recognition unit 6, a bundling and pressing mechanism 8, and an automatic bundling unit 7 installed on the frame 1.

[0027] The scattered wire harness feeding unit 2 is located at one end of the frame 1 and is used to clamp the root of the wire harness to be processed and to convey the scattered wire ends to the single wire separation unit 3.

[0028] The single-line separation unit 3 is disposed adjacent to the output side of the feeding unit. This unit includes a vibrating dispersion platform 31, which is mounted on the frame 1 by elastic support components such as rubber damping columns or springs 32. It is capable of performing micro-amplitude high-frequency vibration, and an eccentric vibration motor 33 is fixedly connected to the bottom of the platform.

[0029] During operation, the motor drives the platform to vibrate, which shakes apart the originally stacked and tangled loose wire bundles and lays them flat on the platform for easy subsequent gripping.

[0030] The transfer robot 5 is positioned across the top of the system, and its range of motion covers the three areas of separation, identification, and sorting. This robot is typically an XYZ three-axis Cartesian coordinate robot or a SCARA robot. The end of the transfer robot 5 is equipped with a pneumatic gripper for picking up a single wire from the vibration dispersion platform 3131 and transporting it to the subsequent workstation.

[0031] Furthermore, in some embodiments, the transfer robot 5 adopts a three-axis Cartesian coordinate robot structure. In order to achieve precise movement in the X, Y, and Z directions, the transfer robot 5 mainly consists of an X-axis longitudinal movement module, a Y-axis lateral movement module, a Z-axis lifting module, and an end effector connecting plate.

[0032] More specifically, in some embodiments, the X-axis longitudinal movement module is fixedly installed on the top frame of the frame 1, responsible for the long-distance back-and-forth transport of the robot between the "single-line separation unit 3" and the "mobile comb sorting unit 4". The X-axis longitudinal movement module includes an X-axis fixed beam, an X-axis linear guide, an X-axis ball screw, and an X-axis servo motor. The X-axis fixed beam is horizontally mounted on the columns on both sides of the frame 1. The X-axis ball screw is installed on the X-axis fixed beam. The X-axis servo motor is connected to one end of the X-axis ball screw through a coupling. The X-axis linear guide is installed on both sides of the X-axis ball screw. The X-axis slide is threaded to the X-axis ball screw through a screw nut, and the X-axis slide is slidably engaged with the X-axis linear guide.

[0033] The operating principle of the X-axis longitudinal movement module is as follows: the X-axis servo motor drives the X-axis ball screw to rotate, thereby causing the X-axis slide mounted on the screw nut to move horizontally and longitudinally along the X-axis linear guide.

[0034] More specifically, in some embodiments, the Y-axis lateral movement module is mounted on the X-axis slide and moves with the X-axis. It is responsible for adjusting the lateral position of the gripping point and the dropping point, such as aligning with the comb tooth slots at different positions. In some embodiments, the Y-axis lateral movement module includes a Y-axis cantilever beam, a Y-axis linear guide, a Y-axis lead screw, a Y-axis servo motor, and a Y-axis slide. Specifically, the Y-axis cantilever beam is vertically fixed on the X-axis slide in a cross-shaped arrangement. The Y-axis ball screw is mounted on the Y-axis fixed beam. The Y-axis servo motor is connected to one end of the Y-axis lead screw via a coupling. The Y-axis linear guide is mounted on both sides of the Y-axis lead screw. The Y-axis slide is threaded to the Y-axis lead screw via a lead screw nut, and the Y-axis slide is slidably engaged with the Y-axis linear guide.

[0035] The operating principle of the Y-axis lateral movement module is as follows: the Y-axis servo motor drives the Y-axis lead screw to rotate, thereby causing the Y-axis slide to move horizontally along the guide rail on the Y-axis cantilever beam.

[0036] More specifically, in some embodiments, the Z-axis vertical module is vertically mounted on the front end of the Y-axis slide, responsible for performing the lowering and lifting actions when gripping the wire. In some embodiments, the Z-axis vertical module includes a Z-axis support plate, a Z-axis slide rail, a Z-axis lead screw, a Z-axis motor with brake, and a Z-axis lifting slider. Specifically, the Z-axis support plate is vertically fixed on the Y-axis slide, the Z-axis lead screw is mounted on the Z-axis support plate, the Z-axis motor with brake is connected to one end of the Z-axis lead screw via a coupling, the Z-axis slide rail is mounted on both sides of the Z-axis lead screw, and the Z-axis lifting slider is threadedly engaged with the Z-axis lead screw via a lead screw nut, and the Z-axis lifting slider is slidably engaged with the Z-axis slide rail.

[0037] The operating principle of the Z-axis vertical module is as follows: the Z-axis motor drives the lead screw to rotate, which in turn drives the Z-axis lifting slider to move up and down along the vertical guide rail.

[0038] It should be noted that the pneumatic gripper is mounted on the bottom flange of the Z-axis lifting slider.

[0039] Furthermore, the working principle of this transfer robot 5 is as follows: During material handling, the transfer machine moves to the top of the separation unit via the X-axis longitudinal movement module, finely adjusts the alignment with the guide wire via the Y-axis lateral movement module, and achieves Z-axis descent for gripping and Z-axis ascent via the Z-axis lifting module. During sorting, based on the recognition results of the visual recognition unit 6 and the real-time position of the comb sorting unit, the transfer robot 5 is driven to move along the X and Y axes to the top of the target sorting slot, descends along the Z axis to press the wire into the slot, the pneumatic gripper releases, and rises along the Z axis to reset.

[0040] The movable comb sorting unit 4 is located downstream of the single-line separation unit 3, and the movable comb sorting unit 4 has two structures.

[0041] like Figure 2 As shown, in the first structure, the movable comb tooth sorting unit 4 includes a first comb tooth mounting base plate 41 and a first sliding comb tooth rack 42. The first comb tooth mounting base plate 41 is fixed on the frame 1. The first sliding comb tooth rack is slidably engaged on the guide rail of the first comb tooth mounting base plate 41 and extends in a direction perpendicular to the wire harness axis. The upper surface of the first sliding comb tooth rack is provided with a plurality of first U-shaped sorting grooves 43 perpendicular to the wire harness axis along the length direction.

[0042] like Figure 3 As shown, in the second structure, the movable comb tooth sorting unit 4 includes a second comb tooth mounting base plate 44 and a second sliding comb tooth rack 45. The second comb tooth mounting base plate 44 is fixed on the frame 1. The second sliding comb tooth rack is slidably engaged on the guide rail of the second comb tooth mounting base plate 44 and extends in a direction perpendicular to the wire harness axis. The upper surface of the second sliding comb tooth rack is provided with a plurality of second U-shaped sorting grooves 46 parallel to the wire harness axis direction along the length direction.

[0043] The second U-shaped sorting groove 46 has elastic retaining pieces 47 fixedly provided on both sides of the groove opening. The free end of the elastic retaining piece 47 extends towards the center of the groove opening and forms a contracted opening 471.

[0044] The movable comb tooth sorting unit 4 also includes a drive screw 48 mounted on the second comb tooth mounting base plate 44. The drive screw 48 is threadedly engaged with the second sliding comb tooth rack 45, so that the second sliding comb tooth rack 45 moves in a straight line under the rotation of the drive screw 48. The input end of the drive screw 48 is connected to a drive component 49, wherein, in this embodiment, the drive component 49 is a drive motor.

[0045] In actual operation, the drive unit 49 receives a control signal and starts to output rotational power. The output shaft of the drive motor 49 drives the drive screw 48 connected to it to rotate. Since there is a threaded engagement between the drive screw 48 and the second sliding comb tooth rack 45, and the drive screw 48 is mounted on the base plate 44, the rotational movement of the screw forces the second sliding comb tooth rack 45 meshing with it to produce axial displacement.

[0046] Furthermore, the aforementioned movable comb tooth sorting unit 4 is further optimized. In this optimized embodiment, a base plate 441 is installed below the second comb tooth mounting base plate 44. An input reciprocating screw 442 is provided on the central axis of the base plate 441. The input reciprocating screw 442 is threadedly engaged with the second comb tooth mounting base plate 44, thereby converting the rotational motion of the input reciprocating screw 442 into linear reciprocating motion. The input end of the input reciprocating screw 442 is connected to an input motor 4421.

[0047] The input reciprocating screw 442 is provided with input guide rails 443 on both sides. Each input guide rail 443 has a sliding slider 444 that slides on it. The sliding slider 444 is fixed to the second comb mounting base plate 44. One end of the telescopic main push rod 445 is hinged to the base plate 441, and the other end is hinged to the central triangular connecting frame 446. The input reciprocating screw 442 is also provided with a mating structure. A movable nut 447 and a central triangular connecting frame 444 are fixedly installed on the movable nut 447. The central triangular connecting frame 446 has an isosceles triangular structure. The left and right base corners of the central triangular connecting frame 446 are respectively pivotally hinged to the beginning ends of the left swing link 4461 and the right swing link 4462. The root of the left cluster claw 4463 is pivotally mounted on the left swing link 4461, and the root of the right cluster claw 4464 is pivotally mounted on the right swing link 4462.

[0048] Furthermore, two position-corresponding limiting plates 4411 are installed on the aforementioned base plate 441. The limiting plates 4411 are provided with limiting grooves 4412 that are matched with the swing connecting rods corresponding to the positions.

[0049] In actual operation, the input motor 4421 drives the input reciprocating screw 442 to rotate, thereby causing the floating nut 447 to reciprocate. During the retraction of the floating nut 447, the central triangular connecting frame 446 retracts, pulling the left swing link 4461 and right swing link 4462 inward. Pulled by the links, the left and right clustering claws 4463 and 4464 open outward around their hinged positions with the swing links. Conversely, during the forward movement of the floating nut 447, the central triangular connecting frame 446 moves forward... As the left and right swing links 4461 and 4462 expand outward, the left and right bundling claws 4463 and 4464 retract inward around their hinged positions with the swing links, thus, as the movable comb-type sorting unit 4 moves along a straight line toward the bundling and pressing mechanism 8, the left and right bundling claws 4463 and 4464 gradually retract, forcibly curling the flattened wires and clustering them toward the center, achieving pre-bundling of the wire harness and improving the bundling effect of the subsequent bundling and pressing mechanism 8.

[0050] The bundling and clamping mechanism 8 is located between the movable comb sorting unit 4 and the automatic bundling unit 7. The bundling and clamping mechanism 8 includes a pair of arc-shaped clamps 81 arranged vertically opposite each other. After all the wires have been arranged into the comb slots in sequence and entered the bundling and clamping mechanism 8, the arc-shaped clamps 81 close relative to each other under the drive of a cylinder. Since the inner surface of the arc-shaped clamps 81 is arc-shaped and covered with a polished chrome-plated layer, it can smoothly and forcibly gather the wires that were originally arranged in a row into a cylindrical wire bundle without damaging the wire insulation.

[0051] The automatic bundling unit 7 is located at the end. Preferably, in this embodiment, the automatic bundling unit 7 adopts a commercially available automatic wrapping machine. Of course, an automatic cable tie machine or other structures can also be used. After the wire harness is gathered into the arc-shaped clamp 81, the automatic bundling unit 7 wraps and bundles the wire harness to complete the finished product manufacturing.

[0052] For example, in some embodiments, the automatic strapping unit 7 includes a rotating arm, a tape supply reel, and a cutting mechanism. The rotating arm is supported and installed by a rotating bearing seat, and a through hole for the wire harness to pass through is provided at the axis. The tape supply reel is rotatably installed on the outer side wall of the rotating arm, and the cutting mechanism is located beside the rotation trajectory of the rotating arm.

[0053] The integrated intelligent sorting and bundling system for multi-core wire harnesses provided in this embodiment works as follows: S1, Loading and Initialization: S101, manual or automatic feeding: the operator places one end of the loose multi-core wire harness with the outer sheath removed and the inner core exposed on the feeding conveyor belt of the loose wire harness feeding unit 2.

[0054] S102, the transfer robot 5 returns to the origin, and the single-line separation unit 3 is in standby high position.

[0055] S2, Vibrational Dispersion and Single-Line Absorption: S201, Vibration and dispersion platform 31 is started. It uses high-frequency vibration to shake apart the piled-up loose wire ends and spread them as flat as possible on the platform. S202, suction, the adsorption separation head descends to contact the surface of the lead wire, the vacuum generator activates to generate negative pressure, sucking up the uppermost free lead wire, and then raising it to the junction height.

[0056] S3, Visual Recognition and Line Sequence Matching: S301, Grab and transfer: The transfer robot arm 5 moves to below the separation head, and the pneumatic gripper closes to clamp the wire; S302, identification and judgment, ring light source 61 supplementary lighting, industrial camera 62 captures wire image, image processing algorithm extracts wire color or characters; S4, Dynamic comb tooth sorting: S401, Precision insertion into the slot: The transfer robot descends along the 5Z axis to press the yellow wire into the slot. S402, Cycle: The transfer robot 5 releases and returns to the separation unit, repeating steps S2 to S4 until all wires have been sequentially filled into the moving comb-type sorting unit 4. At this point, the scattered wire bundle has been transformed into a neatly arranged planar wiring harness on the moving comb-type sorting unit 4.

[0057] S5, Bundling and Automatic Strapping: S501, Bundling: When the movable comb-tooth sorting unit 4 is fully loaded, the bundling and clamping mechanism 8 is activated. The upper and lower arc-shaped clamps 81 push and gather the wires laid flat on the movable comb-tooth sorting unit 4 towards the center, ultimately forming a tight circular wire bundle.

[0058] S502, winding, automatic bundling unit 7 intervenes, automatic bundling unit 7 winds and bundles the wire harness to complete the finished product production.

[0059] S6, Finished product unloading: S601, release, the arc-shaped clamp 81 opens, and the sliding comb toothed rack resets; S602, push out, the discharge push rod pushes the bundled finished wire harness out of the workstation and slides into the finished product collection box.

[0060] like Figure 6 as well as Figure 7As shown, in some embodiments, the clustering and clamping mechanism 8 is improved. In some embodiments, the clustering and clamping mechanism 8 includes a clamping drive seat 82, a multi-faceted clamping block 83, and a locking mechanism. There are two clamping drive seats 82. The clamping drive seats 82 are provided with a pneumatic drive cylinder or electric drive cylinder 84 on their sides to drive the clamping drive seats 82 to move, which is used to control the opening and closing of the two clamping drive seats 82. The multi-faceted clamping block 83 is rotatably mounted on the clamping drive seat 82. The multi-faceted clamping block 83 has two working surfaces, one of which is a clustering surface 831 and the other is a flat surface 832.

[0061] Specifically, in some embodiments, the bundle surface 831 is a semi-circular or V-shaped groove structure, and anti-slip texture is provided on the inner surface of the bundle surface 831.

[0062] In some embodiments, the plane 832 adopts a flat planar structure, and the upper and lower edges of the plane 832 are provided with flexible limiting edges.

[0063] Furthermore, a locking mechanism can be designed on the bundle clamping mechanism 8. Specifically, the locking mechanism includes two positioning spring pins set on the multi-faceted clamping block 83. The two positioning spring pins are respectively set in the bundle surface 831 and the plane surface direction. A positioning groove with a matching structure to the positioning spring pin is provided on the clamping drive seat 82 so as to lock the multi-faceted clamping block 83 in the position of the bundle surface 831 or the plane surface 832.

[0064] Specifically, by rotating the multi-faceted clamping block 83, the above structure allows the clustering and clamping mechanism 8 to switch between two states, thereby obtaining two completely different finished product effects, greatly expanding the applicability of the equipment.

[0065] The first usage mode is the circular bundle mode. Specifically, the operator or control system locks the multi-faceted clamps 83 on both sides, so that the two bundle surfaces 831 face each other. When the bundle clamping mechanism 8 is closed, the two semicircles on the left and right close together to form a closed circular channel. Then, after the transfer robot 5 puts the wires of the movable comb sorting unit 4 into the bundle, the bundle clamping mechanism 8 closes, and the bundle surface 831 forcibly squeezes the originally flat wire bundle towards the center, overcoming the elasticity of the wire bundle and gathering the wires into a tight cylinder.

[0066] Furthermore, the circular wire bundle generated through the circular bundling pattern has a circular cross-section and the smallest diameter.

[0067] The second usage mode is the flat cabling mode. Specifically, the operator or control system rotates the multi-faceted clamping block 83 so that the two flat surfaces 832 are arranged opposite each other and locked. When the bundling and pressing mechanism 8 is closed, the two flat surfaces are parallel and close together, but not in complete contact, forming a flat rectangular channel. Furthermore, when the bundling and pressing mechanism 8 is closed, the flat surfaces 832 do not squeeze the cable bundle into a bunch, but rather "clamp" and "flatten" the cable bundle in the horizontal direction, using the guard edges of the upper and lower edges of the surfaces to prevent the cable bundle from spreading out vertically.

[0068] Furthermore, the wire harnesses generated by the flat cabling mode maintain the flat arrangement state when the comb teeth are sorted, with a cross-section that is straight or rectangular, and no crossing or twisting between the wires.

[0069] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions or improvements made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
