Description

Technical Field

[0001] The utility model relates to the field of wire harness processing, in particular to a wire harness glue wrapping device. Background Art

[0002] During the production of wire harnesses, glue is usually wrapped around the wire harnesses to enhance their strength and protect them.

[0003] A Chinese patent application with publication number CN117699126A discloses a device for winding an adhesive tape around a wiring harness, comprising: a stator ring, which is provided with a central cavity and a first notch extending through the central cavity; a rotor disk, which is mounted on the central cavity of the stator ring, and the rotor disk is provided with a central hole and a second notch extending through the central hole, when the rotor disk rotates until the second notch is opposite to the first notch, the wiring harness passes through the first notch and the second notch and enters the central hole; a driving mechanism, which is used to drive the rotor disk to rotate; a reel, which is mounted on one side of the rotor disk, when the reel rotates with the rotor disk; a limiting component, which includes two, the two limiting components are respectively located at the front and rear sides of the adhesive tape; the two limiting components are coaxial with the central hole, and the limiting component has a limiting hole; the limiting component is configured such that: when the wiring harness is assembled, the limiting component allows the wiring harness to radially enter the limiting hole, and when the adhesive tape is wound around the wiring harness, the limiting component restricts the wiring harness from escaping from the limiting hole.

[0004] The above-disclosed device for winding tape around a wiring harness has a rotor disk driving the tape to rotate, so that the tape is wound around the wiring harness. However, the tape is only guided by a guide component in the path from being led out to being wound around the wiring harness. The guide component is simply provided with an opening, and the tape is simply guided through the opening. In the process of wrapping the tape around the wiring harness, because a sufficient length of tape needs to be wrapped axially around the wiring harness, the wiring harness needs to be moved along the axial direction to meet the length requirement of the tape. When the wiring harness moves, a certain dragging force is applied to the tape. With only simple guidance, the tape can easily be wrinkled under the action of dragging, thereby affecting the quality of the tape wrapping. Improvements are needed. Utility Model Content

[0005] The utility model aims to provide a wire harness glue wrapping device, which has the advantages of preventing wrinkles from being generated due to the dragging force on the adhesive tape during glue wrapping and ensuring the glue wrapping quality.

[0006] In order to achieve the above-mentioned purpose and other related purposes, the utility model provides the following technical solutions: a wire harness wrapping device, comprising a support body, a swivel and a rotating drive member, and also comprising:

[0007] A mounting seat fixed to the rotating ring, wherein a mounting shaft for mounting a tape roll is rotatably connected to the mounting seat;

[0008] A stopper assembly disposed on the mounting shaft and used to axially fix the tape roll on the mounting shaft; and

[0009] A smoothing component is arranged on the mounting seat and is used to smooth the tape led out from the tape roll. The smoothing component includes a plate and a b plate. One side of the a plate is recessed with a passing groove with a width only for the tape to pass through. The b plate is arranged on the a plate and respectively abuts against the two sides of the tape passing through the passing groove.

[0010] Through the above technical scheme, the tape roll is first fixed on the mounting shaft, and then the tape is led out and pre-bonded to the wiring harness after passing through the through slot. Then the rotating driving member drives the swivel to rotate, thereby driving the tape roll to perform orbital motion so that the tape is wound around the wiring harness. During this process, the limiting component restricts the tape roll from lateral movement, and the tape led out through the slot also cannot move laterally, so that the tape always moves along the same path and enhances stability. At the same time, during the process of the tape being pulled, the a plate and the b plate restrict the tape from moving perpendicular to the direction of the tape surface when passing through the through slot, so that the tape cannot generate wrinkles on the path from being led out from the tape roll to passing through the through slot, reducing the probability of wrinkles, thereby ensuring the quality of the tape wrapping.

[0011] In one embodiment of the present invention, the b plate is slidably assembled with the a plate, the sliding direction is the same as the length direction of the through slot, and the b plate is fixed with the a plate by a locking member.

[0012] Through the above technical solution, the fixing position of the b plate can be adjusted according to the thickness of the adhesive tape used, thereby improving adaptability.

[0013] In an embodiment of the present invention, the locking member is configured as a bolt.

[0014] Through the above technical solution, it is convenient to disassemble and fix multiple times, so that the relative position of the b plate and the a plate can be flexibly adjusted.

[0015] In one embodiment of the present invention, a first roller and a second roller are respectively disposed on the a plate and the b plate, and the first roller and the second roller limit the length of the through slot to match the thickness of the tape.

[0016] Through the above technical solution, the first roller and the second roller are used instead of the a plate and the b plate to contact the tape. The use of the rollers in contact with the tape can avoid wear of the tape when it is pulled and improve the smoothness of the tape withdrawal.

[0017] In an embodiment of the present invention, the limiting assembly includes a first limiting member fixed to the mounting shaft and a second limiting member detachably mounted on the mounting shaft, and the first limiting member is disposed between the mounting seat and the second limiting member.

[0018] Through the above technical solution, the tape roll can be installed on the mounting shaft after the second limiting member is removed from the mounting shaft, and the second limiting member can be reinstalled back on the mounting shaft after the tape roll abuts against the first limiting member, so the installation of the tape roll is simple and convenient.

[0019] In one embodiment of the present invention, a counterweight block is further provided on the swivel for balancing the center of gravity.

[0020] Through the above technical solution, the rotation center of gravity of the swivel is stabilized and the stability is improved.

[0021] In one embodiment of the present invention, the swivel is provided with an inlet for the wire harness to pass through.

[0022] Through the above technical solution, it is convenient for the wire harness to reach the glue wrapping position in the middle of the swivel.

[0023] In one embodiment of the present invention, a cutting knife is further included which is fixed to the mounting base.

[0024] According to the technical solution, after wrapping the adhesive around the wire harness, the adhesive tape can be cut off by a cutter, which makes the use more convenient.

[0025] As described above, the wire harness wrapping device of the utility model has the following beneficial effects:

[0026] The tape roll is first fixed on the mounting shaft, and then the tape is led out and passed through the through slot to be pre-bonded to the wiring harness. Then the rotating driving member drives the swivel to rotate, thereby driving the tape roll to perform a revolution so that the tape is wound around the wiring harness. During this process, the limit assembly restricts the tape roll from lateral movement, and the tape led out through the slot also cannot move laterally, so that the tape always moves along the same path and enhances stability. At the same time, when the tape is pulled, the a plate and the b plate restrict the tape from moving perpendicular to the surface of the tape when passing through the through slot, so that the tape cannot generate wrinkles on the path from being led out from the tape roll to passing through the through slot, reducing the probability of wrinkles, thereby ensuring the quality of the tape wrapping.
