Description

Technical Field

[0001] This application relates to the field of wire harness processing technology, and in particular to a wire harness carrying device for terminal crimping. Background Technology

[0002] Terminal crimping is a core process in wire harness connections in industries such as electronics, automotive, and electrical equipment, and its quality directly affects the electrical performance and structural stability of the product. Currently, terminal crimping equipment on the market is mainly divided into two categories: manually operated equipment and semi-automatic equipment, both of which have several technical drawbacks. Manually operated equipment relies on workers manually feeding the wire harness, placing the terminals, and starting the crimping process. This is not only labor-intensive and inefficient, but also prone to human error leading to misalignment between the terminals and the wire harness, resulting in loose crimps, poor contact, and other problems, thus affecting product yield.

[0003] Although semi-automatic equipment has automated some processes, the wire harness feeding is mostly based on a passive drag design, which lacks an effective anti-drop and stable conveying structure. This makes it easy for wire harnesses to become loose or displaced, resulting in a low yield rate in subsequent crimping processes. Manual assistance in positioning or replenishing materials is often required, which is not only inefficient but also prone to errors due to manual operation. Utility Model Content

[0004] In order to solve the problems mentioned in the background art, this application provides a wire harness carrying device for terminal crimping.

[0005] This application provides a wire harness carrying device for terminal crimping, which adopts the following technical solution:

[0006] A wire harness carrying device for terminal crimping includes a central shaft, the bottom end of which is mounted on a support base. A drive motor is mounted on the support base. A bushing is rotatably fitted on the central shaft. A transmission assembly connects the output shaft of the drive motor and the bushing. A turntable is mounted on the upper end of the bushing. A plurality of clamping assemblies for placing wire harnesses are circumferentially arranged on the upper surface of the turntable. Each clamping assembly includes a clamping seat and a clamping member. The clamping seat is mounted on the upper surface of the turntable, and the clamping member is slidably mounted on the clamping seat. A wire harness to be clamped is disposed within the clamping member. A push plate is horizontally arranged on the upper sidewall of the central shaft. The push plate can push the clamping member to slide along the axial direction of the clamping seat, pushing out the end of the wire harness to be crimped.

[0007] To optimize the above technical solution, the specific measures also include:

[0013] Furthermore, the elastic element includes a guide rod, which is distributed along the axial direction of the clamping seat. One end of the guide rod is disposed on the positioning block, and the other end of the guide rod is disposed on the limiting block. A guide block is disposed on the side wall of the clamping sleeve. The guide block is slidably sleeved on the guide rod. The guide block is located between the positioning block and the limiting block. A telescopic spring is disposed between the guide block and the positioning block.

[0014] Furthermore, the upper end of the clamping sleeve is provided with multiple mounting holes, and a clamping component is provided in the mounting holes. The lower end of the clamping component can abut against the wire harness.

[0015] Furthermore, the clamping assembly includes a limiting cap, which is disposed above the mounting hole. A compression member is disposed inside the limiting cap, one end of which abuts against the upper end inside the limiting cap, and a damping ball is disposed at the other end of the compression member.

Detailed Implementation

[0029] To make the above-mentioned objectives, features and advantages of this utility model more apparent and understandable, the specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings.

[0030] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Those skilled in the art can make similar extensions without departing from the spirit of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0031] like Figures 1-5 As shown, a wire harness carrying device for terminal crimping is used to place a wire harness 80 with processed terminals. It includes a central shaft 10, a support base 20, a turntable 30, a drive motor 40, and a transmission assembly 50. The bottom end of the central shaft 10 is set on the support base 20. The drive motor 40 is set on the support base 20. A bushing 60 is rotatably sleeved on the central shaft 10. The output shaft of the drive motor 40 and the bushing 60 are connected by the transmission assembly 50. A turntable 30 is set on the upper end of the bushing 60. A plurality of clamping assemblies 70 for placing the wire harness 80 are circumferentially arranged on the upper surface of the turntable 30. A push plate 11 is horizontally arranged on the upper side wall of the central shaft 10. The push plate 11 can push the wire harness 80 to slide away from the axis of the turntable 30, pushing out the end of the wire harness 80 that needs to be crimped, so as to facilitate subsequent crimping.

[0032] The support base 20 is placed horizontally, and a mounting plate 21 is vertically installed at one end of the support base 20. The mounting plate 21 can be used to connect to external equipment.

[0033] The drive motor 40 is vertically mounted on the support base 20. The fixed end of the drive motor 40 is located on the lower surface of the support base 20. The output shaft of the drive motor 40 passes through the support base 20 upwards. A limit plate 41 is provided at the end of the output shaft of the drive motor 40.

[0034] The transmission assembly 50 includes a first transmission wheel 51, a second transmission wheel 52, and a transmission belt 53. The first transmission wheel 51 is mounted on the output shaft of the drive motor 40, the second transmission wheel 52 is mounted on the bushing 60, and the transmission belt 53 is mounted on the first and second transmission shafts. The diameter of the first transmission wheel 51 is smaller than the diameter of the second transmission wheel 52. The diameter ratio of the first transmission wheel 51 to the second transmission wheel 52 is set according to the distance between adjacent clamping assemblies 70. Based on the set diameter ratio, the output shaft of the drive motor 40 can rotate one revolution, and the turntable 30 can rotate by a set angle, i.e., the distance between adjacent clamping assemblies 70.

[0035] An annular groove 61 is provided at the lower end of the bushing 60, and the second transmission wheel 52 is disposed in the annular groove 61. The limiting plate 41 on the output shaft of the drive motor 40 can limit the first transmission wheel 51 to prevent the first transmission wheel 51 from disengaging from the output shaft of the drive motor 40 in extreme cases.

[0036] The clamping assembly 70 includes a clamping seat 71 and a clamping member 72. The clamping seat 71 is disposed on the upper surface of the turntable 30 and serves as a guide and support.

[0037] The clamping member 72 is slidably mounted on the clamping base 71. A wire harness 80 with terminals to be crimped is disposed within the clamping member 72. The push plate 11 can push the clamping member 72 to slide along the axial direction of the clamping base 71, pushing out the end of the wire harness 80 that needs to be crimped. The clamping member 72 includes a clamping sleeve 721, which is slidably mounted within a groove 711. A through clamping channel is formed within the clamping sleeve 721, and the wire harness 80 is disposed within the clamping channel. Specifically, a slide 722 is provided at the bottom of the clamping sleeve 721, and a groove 711 is formed on the upper surface of the clamping base 71 along its axial direction. The slide 722 is slidably mounted within the groove 711.

[0038] A protrusion 723 is provided on the side of the slide table 722 near the central axis 10. One end of the wire harness 80 abuts against the protrusion 723, and the end of the protrusion 723 opposite to the wire harness 80 can slide in contact with the push plate 11. A roller 724 is rotatably provided on the end of the protrusion 723 opposite to the wire harness 80. An arc-shaped surface 111 is provided on the side of the push plate 11 near the protrusion 723. The roller 724 can rotate on the arc-shaped surface 111. Limiting rings 725 are provided on both sides of the roller 724. The upper and lower sides of the limiting rings 725 abut against the upper and lower surfaces of the push plate 11, respectively.

[0039] During the rotation of the turntable 30, when the clamping seat 71 moves closer to the push plate 11, the protrusion 723 on the clamping seat 71 will first contact one side of the arc surface 111 of the push plate 11. Then, as the clamping seat 71 continues to move, the roller 724 on the protrusion 723 will slide on the arc surface 111. During the sliding of the protrusion 723, it will push the clamping seat 71 to move away from the push plate 11. When the protrusion 723 moves to the farthest end of the arc surface 111 on the push plate 11, the end of the wire harness 80 on the clamping seat 71 that is away from the push plate 11 will protrude and can be used for clamping subsequent terminals.

[0040] Then the turntable 30 continues to rotate. In order for the clamping seat 71 to spring back and reset, elastic elements 73 are provided on both sides of the clamping sleeve 721 on the clamping seat 71. The clamping sleeve 721 is slidably connected to the elastic elements 73. Positioning blocks 74 are provided on both sides of the clamping seat 71. One end of the elastic element 73 is connected to the positioning block 74. Among them, the elastic element 73 includes a guide rod 731, which is distributed along the axial direction of the clamping seat 71. One end of the guide rod 731 is provided on the positioning block 74, and the other end of the guide rod 731 is provided with a limit block 732. A guide block 75 is provided on the side wall of the clamping sleeve 721. The guide block 75 is slidably sleeved on the guide rod 731. The guide block 75 is located between the positioning block 74 and the limit block 732. A telescopic spring 733 is provided between the guide block 75 and the positioning block 74.

[0041] The recovery process of the elastic element 73 is as follows: In the initial state, the elastic force of the telescopic spring 733 pushes the guide block 75 away from the positioning block 74, so that the guide block 75 abuts against the limiting block 732. When the protrusion 723 of the clamping sleeve 721 contacts the push plate 11, the guide block 75 begins to compress the telescopic spring 733. As the push plate 11 pushes, the telescopic spring 733 is compressed to its maximum stroke. When the wire harness 80 finishes crimping the terminal, the telescopic spring 733 begins to return, pushing the guide block 75 away from the positioning block 74 until the telescopic spring 733 returns to its initial state, thus completing one cycle of the clamping sleeve 721.

[0042] Meanwhile, considering that the turntable 30 will generate centrifugal force or other shaking during rotation, in order to maintain a stable clamping state of the wire harness 80, multiple mounting holes are provided at the upper end of the clamping sleeve. The number and size of the mounting holes, as well as the spacing between the mounting holes, can be set as needed, and are not specifically limited in this embodiment. A clamping component 90 is provided in the mounting hole, and the lower end of the clamping component 90 can abut against the wire harness 80. The clamping component 90 includes a limiting cap 91, which is located above the mounting hole. A compression member is provided inside the limiting cap 91. One end of the compression member abuts against the upper end inside the limiting cap 91, and the other end of the compression member is provided with a damping ball 92, which passes through the mounting hole and abuts against the upper surface of the wire harness 80. The compression component includes a compression spring 93 and a limiting post 94. One end of the compression spring 93 is located at the upper end inside the limiting cap 91, and the other end of the compression spring 93 is connected to the limiting post 94. A damping ball 92 is provided on the side of the limiting post 94 away from the compression spring 93, and the limiting post 94 is inserted into the mounting hole.

[0043] The working principle of the clamping component 90 is as follows:

[0044] In the initial state, the damping ball 92 is inserted into the clamping channel inside the clamping sleeve 721. When the wire harness 80 is inserted into the clamping channel of the clamping sleeve 721, the wire harness 80 will squeeze the damping ball 92, causing the damping ball 92 to rise upwards. Then, due to the elastic force of the compression spring 93, the damping ball 92 will press against the wire harness 80, thereby fixing the wire harness 80. This method can adapt to wire harnesses 80 of different diameters, improving the adaptability of the device.

[0045] The operating principle of this device is as follows:

[0046] First, the wire harness 80 to be processed is placed into the corresponding clamping sleeve 721. Then, the drive motor 40 is started, and the bushing 60 is rotated through the transmission component 50. During the rotation, the roller 724 on the protrusion 723 slides on the arc surface 111 on the push plate 11, so that the clamping sleeve 721 is pushed to move away from the push plate 11. Then, the terminal is crimped using an external device. Then, the drive motor 40 is started again, and the clamping sleeve 721 is reset under the action of the compression spring 93, thereby completing the processing of the wire harness 80 on the current clamping sleeve 721. Then, the cycle repeats.
