Description

Technical Field

[0001] This utility model relates to the field of wire harness winding tape technology, and in particular to a wire harness winding tape machine. Background Technology

[0002] A wire harness winding and tape wrapping machine is an automated processing equipment that integrates wire harness winding and tape wrapping functions. It is mainly used to mechanically wind long strip wire harnesses into regular coils, such as electronic cables, automotive wire harnesses, and industrial control wire harnesses, while simultaneously wrapping tape to fix the coil shape and prevent loosening or deformation. This type of equipment is widely used in electronics manufacturing, automotive industry, aerospace, and home appliance assembly, with its core demand stemming from the requirements for large-scale and precision wire harness processing. Although some semi-automatic winding or tape wrapping equipment has emerged in the existing technology, it still has significant limitations in practical applications. The wire structure of traditional winding equipment is mostly fixed in diameter, which cannot dynamically adjust the guide gap according to the specifications and material characteristics of the wire harness. The clamping plates used are mostly designed with fixed claws, which can only adapt to a single specification of wire harness. When changing the type of wire harness, the clamping components need to be disassembled and replaced, which is cumbersome. Moreover, the radial movement of the winding claw is mostly adjusted by manual knobs, resulting in low positioning accuracy. It is also inconvenient to completely remove the wound wire harness when picking it up. Most equipment relies on manual assistance to push the wire harness or uses a unidirectional conveyor belt, which cannot achieve precise reciprocating motion control along the wire harness travel path. This results in large errors in the number of coil turns, and the matching degree between the conveying speed and the winding speed is low, which easily leads to wire harness accumulation or excessive stretching. Therefore, developing specialized equipment that can automate winding, facilitate handling, and integrate tape wrapping functions has become key to improving the productivity and quality of the wire harness processing industry. Utility Model Content

[0003] In view of at least one of the above technical problems, the present invention provides a wire winding and tape wrapping machine, which adopts an integrated design of a winding structure composed of an adjustable wire group and a clamping disc and a tape wrapping structure, so as to improve the adaptability to multiple specifications of wire harnesses and improve the working efficiency and accuracy of wire harness winding and tape wrapping.

[0004] This utility model provides a wire winding and tape wrapping machine, comprising: Workbench; A winding structure, mounted on the workbench, includes: The wire guide is used to guide the wire bundle to be wound. The conductor group is located on the path of the wire harness at the conductor port, with gaps in the middle for the wire harness to pass through, and moves in a straight line in the direction of approaching or away from the path of the wire harness. A gripper disc is disposed on the wire harness travel path at the wire inlet and is rotatably mounted with the worktable. A gripper block is disposed on one side of the gripper disc and several winding claws are disposed on the other side. A drive block is disposed through the gripper disc, the gripper block and the winding claws at corresponding positions. The drive block drives the winding claws to move in a direction closer to or away from the axis of the gripper disc. A clamping block is disposed on one side of the winding claws on the gripper disc for clamping the wire harness. A conveying assembly, installed on one side of the wire inlet, reciprocates along the wire harness travel path to convey the wire harness; A tape-wrapping structure, mounted on the workbench, is used to wrap tape around wire harnesses.

[0005] In some embodiments of this utility model, the conductor group includes two conductor posts arranged opposite each other, and one conductor post moves toward or away from the other conductor post.

[0006] In some embodiments of this utility model, the conductor assembly further includes a movable seat disposed on one side of the conductor post, the movable seat driving the conductor post to move in a straight line toward or away from the wire harness travel path.

[0007] In some embodiments of this utility model, the inner wall of the wire opening is funnel-shaped, and the diameter of the inner wall decreases with the direction of the wire bundle's travel path.

[0008] In some embodiments of this utility model, an adaptation block is provided on the side of the gripper disc opposite to the gripper block, and the adaptation block passes through the gripper disc and is fixedly connected to the gripper block.

[0009] In some embodiments of this utility model, rollers that are tactilely connected to the adapting block are provided on the gripper disc.

[0010] In some embodiments of this utility model, a first driving component is provided on one side of the adapting block and mounted on the gripper disk. A limiting block is provided at one end of the first driving component near the adapting block. The limiting block abuts against the roller. The first driving component drives the limiting block to move toward or away from the roller.

[0011] In some embodiments of this utility model, the side of the limiting block that abuts against the roller is sloped, with the side closer to the first driving component being higher than the side farther from the first driving component.

[0012] In some embodiments of this utility model, the tape wrapping structure includes: An opening slot is provided facing one side, and a C-shaped gear ring is rotatably connected to the opening slot. The C-shaped gear ring is initially positioned in the same direction as the opening slot. An unwinding assembly, fixed to the worktable, is used for unwinding the tape. A tape-pulling assembly is set on the workbench and positioned vertically in the opening slot, for clamping the tape end and pulling it to the lower side of the opening slot. A tape cutting assembly is disposed above the opening of the slot and is used for cutting tape.

[0013] In some embodiments of this utility model, the C-shaped toothed ring also has two clamping members arranged opposite to each other, which are arranged in an arc shape towards the opening of the C-shaped toothed ring, and are movable in the direction of the wire harness wrapping tape by elastic members.

[0014] The beneficial effects of this utility model are as follows: By setting an adjustable wire group and a flared wire opening, this utility model achieves dynamic guidance and adaptive clamping of the wire harness travel path, thus avoiding wire harness jamming or wear. It effectively solves the problem of poor adaptability of traditional fixed-diameter wire structures and improves the compatibility with multi-specification wire harnesses. Through the drive block driving the winding claw radial movement and the cooperation of the clamping block and the adaptation block, the clamping disk achieves flexible clamping of wire harnesses of different diameters. When it is necessary to remove the wire harness, it can also be quickly released, improving work efficiency. Through the reciprocating movement of the conveying component along the wire harness travel path, the precise coordination of wire harness conveying and winding actions is achieved, resulting in controllable wire harness length.

The term "and / or" as used herein includes any and all combinations of one or more of the associated listed items.

[0021] This utility model provides a method such as Figures 1 to 6 The wire winding and tape wrapping machine shown includes: Workbench 1; Winding structure 2, mounted on workbench 1, includes: The wire inlet 21 is used to guide the wire bundle to be wound. The conductor group 22 is located on the wire harness travel path at the conductor opening 21, with a gap in the middle for the wire harness to pass through, and moves in a straight line towards or away from the wire harness travel path. The gripper disc 23 is located on the wire harness travel path at the wire inlet 21 and is rotatably mounted with the worktable 1. A gripper block 23a is provided on one side of the gripper disc 23, and several winding claws 23b are provided on the other side. A drive block 23c is provided through the gripper disc 23, gripper block 23a, and winding claws 23b at corresponding positions. The drive block 23c drives the winding claws 23b to move towards or away from the axis of the gripper disc 23. A clamping block 23d is provided on one side of the winding claws 23b on the gripper disc 23 for clamping the wire harness. The conveying assembly 24 is installed on one side of the wire inlet 21 and reciprocates along the wire harness travel path to convey the wire harness. The tape wrapping structure 3 is installed on the workbench 1 and is used to wrap the wire harness with tape.

[0022] The working principle of this utility model is as follows: The end of the wire harness with winding is placed into the wire inlet 21. The conveying component 24 clamps the end of the wire harness from the other end of the wire inlet 21, passes it through the wire assembly 22, and places it on the clamping block 23d of the clamping disk 23. At this time, the wire harness is fixed on the clamping disk 23. The driving block 23c drives the winding claw 23b to open away from the axis of the clamping disk 23. At this time, the clamping disk 23 rotates, causing the wire harness to wind around the winding claw 23b until the winding is finished and the rotation stops. The driving block 23c moves towards the axis of the clamping disk 23 to close, and the wire harness can be completely and easily removed. The winding structure 2 is reset to wait for the next winding. Then the wire harness is moved to the tape wrapping structure 3, and the wound wire harness is wrapped with tape to fix it and prevent the wire harness from loosening again. This design effectively solves the wear and adaptation problems of traditional fixed aperture wire structures, significantly improves the compatibility of multi-specification wire harnesses, and improves the efficiency of wire harness winding and the pass rate of tape wrapping.

[0023] In some embodiments of this utility model, such as Figure 3 As shown, the conductor group 22 includes two conductor posts 22a arranged opposite each other, and one conductor post 22a moves toward or away from the other conductor post 22a.

[0024] Of the two guide posts 22a, one is fixed as a reference, while the other moves linearly toward or away from the wire harness via a cylinder or lead screw. The size of the gap between them can be adjusted in real time according to the wire harness diameter. When the wire harness enters, the movable guide post 22a automatically fits against the surface of the wire harness to form an elastic clamp, which avoids the rigid compression of the fixed structure and suppresses the lateral displacement of the wire harness through friction.

[0025] In some embodiments of this utility model, such as Figure 3 As shown, the conductor assembly 22 also includes a movable seat 22b disposed on one side of the conductor post 22a. The movable seat 22b drives the conductor post 22a to move in a straight line toward or away from the wire harness travel path.

[0026] The moving seat 22b is driven by a servo motor or other drive mechanism. It can adjust the moving speed and direction of the lead post 22a in real time according to preset winding parameters (such as pitch and number of turns). When the gripper disc 23 drives the winding claw 23b to rotate, the moving seat 22b synchronously drives the lead post 22a to move along the length of the winding claw 23b, so that the wire harness is wound layer by layer on the winding claw 23b in a spiral trajectory. In contrast, in traditional equipment, because the wire is fixed, the wire harness can only be stacked in the same radial plane, which affects the quality of the subsequent wire harness winding tape.

[0027] In some embodiments of this utility model, the inner wall of the wire opening 21 is funnel-shaped, and the inner wall diameter decreases with the direction of the wire bundle travel.

[0028] The enlarged diameter of the wire inlet 21 eliminates the need for careful calibration when manually inserting the wire harness, and allows for greater positioning error when the robot handles the load, reducing the precision requirements for the wire harness preparation stage. Furthermore, the diameter of the flared outlet is not set too small, making it suitable for wire harnesses of different diameters. When changing to wire harnesses of different specifications, there is no need to disassemble the components, shortening the preparation time.

[0029] In some embodiments of this utility model, such as Figure 4 As shown, an adaptation block 23e is provided on the side of the gripper disk 23 opposite to the gripper block 23d. The adaptation block 23e passes through the gripper disk 23 and is fixedly connected to the gripper block 23d.

[0030] The adapting block 23e drives the clamping block 23d to move toward or away from the clamping disk 23, thereby increasing or decreasing the distance between the clamping block 23d and the clamping disk 23, thus achieving the function of clamping or releasing the wire harness end. When clamping multiple specifications of wire harnesses, there is no need to change different clamping blocks 23d.

[0031] Based on the above embodiments, such as Figure 4 As shown, on the gripper disk 23, the adapting block 23e is provided with rollers 23e1 that are tactilely connected to the adapting block 23e.

[0032] Based on the above embodiments, such as Figure 4 As shown, a first drive assembly 23f is provided on one side of the adapting block 23e and is mounted on the gripper disk 23. A limiting block 23f1 is provided at one end of the first drive assembly 23f near the adapting block 23e. The limiting block 23f1 abuts against the roller 23e1. The first drive assembly 23f drives the limiting block 23f1 to move towards or away from the roller 23e1.

[0033] The side of the adapting block 23e is provided with a freely rotatable roller 23e1, while the first drive component 23f (such as a servo cylinder) drives the limiting block 23f1 to move linearly. The end of the limiting block 23f1 abuts against the surface of the roller 23e1 through an arc-shaped surface. When the drive component pushes the limiting block 23f1 closer to the roller 23e1, the roller 23e1 rolls along the contact surface of the limiting block 23f1, causing the adapting block 23e to move away from the gripper disk 23, thereby causing the clamping block 23d to move closer to the gripper disk 23. The clamping block 23d cooperates with the gripper disk 23 to clamp the wire harness. Conversely, when the limiting block 23f1 retracts, the adapting block 23e can move in the opposite direction under the action of a return spring or other return component, and the clamping block 23d releases the wire harness, making it easier to pick up the wire harness. This design improves the response speed, and the power of the drive component is transmitted smoothly through the roller 23e1, reducing the response time of clamping and releasing actions.

[0034] In some embodiments of this utility model, such as Figure 4 As shown, the side of the limiting block 23f1 that abuts against the roller 23e1 is sloping, and the side closer to the first drive assembly 23f is higher than the side farther away from the first drive assembly 23f.

[0035] The sloping contact surface prevents the roller 23e1 from shifting laterally during back-and-forth rolling and reduces rolling resistance, allowing the roller 23e1 to better drive the back-and-forth movement of the adaptation block 23e, resulting in a faster response speed of the clamping block 23d.

[0036] In some embodiments of this utility model, such as Figure 5 As shown, the tape wrapping structure 3 includes: An opening slot 31 is provided facing one side, and a C-shaped gear ring 32 is rotatably connected to the opening slot 31. The C-shaped gear ring 32 is initially positioned in the same direction as the opening slot 31. The unwinding assembly 33 is fixed on the worktable 1 and is used for unwinding the tape. The tape pulling assembly 34 is set on the workbench 1 and is located in the vertical direction of the opening groove 31. It is used to clamp the end of the tape and pull it to the lower side of the opening groove 31. The tape cutting assembly 35 is positioned above the opening of the slot 31 and is used for cutting the tape.

[0037] When wrapping tape around the wire harness, first place the tape on the unwinding assembly 33, pull the tape assembly 34 to clamp the tape end downwards and pull it straight so that the tape covers the opening groove 31, cut the tape assembly 35 to cut the tape, then the wire harness is pressed against the tape and inserted into the C-tooth ring 32 from the opening groove 31. By rotating the C-tooth ring 32, the remaining part of the tape is wrapped and bonded to the wire harness.

[0038] Based on the above embodiments, such as Figure 5As shown, the C-shaped toothed ring 32 also has two clamping members 32a arranged opposite to each other, which are arranged in an arc-shaped flare towards the opening of the C-shaped toothed ring 32, and are movable in the direction of the wire harness wrapping tape by the elastic member 32b.

[0039] This design allows the free end of the tape to continuously adhere to the wire harness during the rotation of the toothed ring, ensuring that the tape is completely wrapped around the wire harness. Furthermore, the elastic element 32b enhances the applicability of the device, allowing wire harnesses of different specifications to be inserted into the C-shaped toothed ring 32.

[0040] Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claimed utility model. The scope of protection of this utility model is defined by the appended claims and their equivalents.
