Description

Technical Field

[0001] This utility model relates to automated processing equipment, specifically to a wire harness switching device. Background Technology

[0002] The crimping of wire harnesses and terminals has achieved a high degree of automation thanks to terminal crimping machines. There are typically two methods for transferring wire harnesses: one is for workers to manually introduce the wire harness into the crimping machine, and the other is to use an automatic clamping device. Currently, the automatic clamping device is usually used for single-wire operations, meaning only one wire harness is picked up at a time, making it impossible to switch to different types of wire harnesses. While manually introducing the wire harness allows for switching between harness types, the process is cumbersome, and due to the wide variety of wire harness types, it's easy to pick the wrong harness, leading to a lower pass rate. Utility Model Content

[0003] To address the above problems, this utility model proposes a multi-line switchable wire harness switching device.

[0004] This utility model is achieved using the following technical solution:

[0005] This utility model proposes a wire harness switching device, including a gripping device and a wire selection device. The wire selection device includes a moving base, a driving device, and a wire guide tube. The driving device is connected to the moving base to drive the moving base to move. Multiple tube clamps are arranged on the moving base along the moving direction of the moving base. At least two wire guide tubes are loaded on different tube clamps. Different wire harnesses pass through different wire guide tubes. By moving the moving base, the different wire guide tubes are switched to positions facing the gripping device so that the gripping device can pick up and put down the wire guide tubes and wire harnesses.

[0006] Preferably, the conduit includes a hollow tube section and a bend section connected to each other. The bend section and the hollow tube section are provided with through holes for the wire harness to pass through, forming a gripping space for the exposed wire harness in the bend section.

[0007] Preferably, the gripping device includes a first gripping part for gripping hollow tube segments and a second gripping part for gripping wire harnesses that enters the gripping space.

[0008] Preferably, the pipe clamp is an elastic clamp.

[0009] Preferably, with the moving direction of the movable seat as the vertical direction, the gripping device is set on one side of the line selection device in the horizontal direction. Multiple sliding seats are arranged vertically on the movable seat. The sliding seats are slidably connected to the movable seat in the horizontal direction so that they can slide closer to or away from the gripping device. Each pipe clamp is fixedly set on a corresponding sliding seat. The device also includes a push rod, which is arranged opposite to the gripping device. The push rod has a movement stroke that moves closer to or away from the gripping device. The movement stroke of the push rod pushes the sliding seat toward the gripping device.

[0010] Preferably, the line selection device further includes multiple elastic elements corresponding to the number of sliding seats. The two ends of the elastic elements act on the sliding seat and the moving seat respectively to provide a restoring force to the sliding seat when it slides close to the gripping device.

[0011] Preferably, a vertically extending connecting rod is fixedly provided on the movable seat, and one end of the elastic element is hooked onto the connecting rod.

[0012] Preferably, the sliding seat is further provided with a connecting part, the push rod has a "T"-shaped head, and the connecting part is a hook-shaped structure in the horizontal direction with a "C" shape. The connecting part is configured so that the head of the push rod can enter or exit the connecting part by the vertical movement of the sliding seat, thereby realizing the linkage connection or separation of the push rod and the sliding seat.

[0013] Preferably, the device also includes a detector, which is positioned at the location of the corresponding gripping device to detect whether the conduit has been switched to a position facing the gripping device.

[0014] This invention has the following advantages: It utilizes the movement of a movable base to switch different wire harnesses to positions facing the gripping device, thus allowing for the arrangement of various wire harnesses. When processing a specific wire harness is required, the system can quickly switch to that harness. The conduit, serving as a carrier for the wire harness, can be mounted on a clamp or gripped by the gripping device, facilitating both the neat arrangement of multiple different wire harnesses and the switching between them.

[0020] To further illustrate the various embodiments, the present invention provides accompanying drawings. These drawings are part of the disclosure of the present invention and are mainly used to illustrate the embodiments, and can be used in conjunction with the relevant descriptions in the specification to explain the operating principles of the embodiments. With reference to these drawings, those skilled in the art should be able to understand other possible implementations and the advantages of the present invention. Components in the drawings are not drawn to scale, and similar component symbols are generally used to represent similar components.

[0021] The present invention will now be further described in conjunction with the accompanying drawings and specific embodiments.

[0022] See Figure 1-5 As shown in the preferred embodiment of this utility model, a wire harness switching device is provided, including a gripping device 1 and a wire selection device 2. The wire selection device 2 includes a movable base 21, a driving device 22, and a wire guide tube 23. The driving device 22 is connected to the movable base 21 to drive the movable base 21 to move. In this embodiment, the driving device 22 is a lifting driving device used to drive the movable base 21 to move up and down in the vertical direction. In other embodiments, the movable base 21 can also be configured to move in other directions, but the structure of this embodiment is more conducive to reducing the space occupied by the device. A plurality of tube clamps 24 are arranged vertically on the movable base 21, and a plurality of wire guide tubes 23 are loaded on different tube clamps 24. Different wire harnesses 3 pass through different wire guide tubes 23. By moving the movable base 21, the different wire guide tubes 23 are switched to a position facing the gripping device 1, so that the gripping device 1 can pick up and put down the wire guide tubes 23 and the wire harnesses 3.

[0023] The conduit 23 serves as the carrier for the wire harness 3. It can be mounted on the clamp 23 or gripped by the gripping device 1. Using the conduit 23 facilitates the neat arrangement of multiple different wire harnesses 3 and also makes it easier to switch between different wire harnesses 3. In this embodiment, the movement of the movable seat 21 is used to switch different wire harnesses 3 to the position facing the gripping device 1. Therefore, various types of wire harnesses can be arranged. For example, this embodiment has 12 different wire harnesses. When it is necessary to process one type of wire harness, it can be quickly switched to that wire harness.

[0024] The conduit 23 includes a hollow tube section 231 and a bend section 232 connected to each other. The bend section 232 is coaxially provided with a through hole for the wire harness to pass through, forming a gripping space in the bend section 232 to expose the wire harness 3. The gripping device 1 includes a first gripping part 11 corresponding to gripping the hollow tube section 231 and a second gripping part 12 corresponding to gripping the wire harness 3 in the gripping space. The gripping device 1 grips both the conduit 23 and the wire harness 3 simultaneously to ensure the positional accuracy of the wire harness 3.

[0025] like Figure 3 In this embodiment, the pipe clamp 24 is an elastic clamp; in other embodiments, it may be other types of clamps.

[0026] The gripping device 1 is positioned on one side of the line selection device 2 in the horizontal direction, such as... Figure 4 Multiple sliding seats 25 are arranged vertically on the movable seat 21. The sliding seats 25 are slidably connected to the movable seat 21 in the horizontal direction so that they can slide closer to or away from the gripping device 1. Each pipe clamp 24 is fixedly mounted on a corresponding sliding seat 25. The push rod 26 is arranged opposite to the gripping device 1. The push rod 26 has a travel distance that moves closer to or away from the gripping device 1. After each sliding seat 25 is displaced to the position of the corresponding gripping device 1 by the lifting displacement of the movable seat 21, the travel distance of the push rod 26 pushes the sliding seat 25 toward the gripping device 1 so that the gripping device 1 can grip the wire tube 23 and wire harness 3 on the sliding seat 25. It is understood that in other embodiments, the gripping device 1 can be modified to move closer to or away from the wire selection device 2. For example, the gripping device 1 can be configured to have a multi-axis moving mechanism, so that the push rod 26 and the sliding seat 25 are not required. However, the corresponding gripping device and the matching multi-axis moving mechanism require more cost.

[0027] In this embodiment, the line selection device 2 further includes a plurality of elastic elements 27 corresponding to the number of sliding seats 25. The two ends of the elastic elements 27 act on the sliding seats 25 and the movable seat 21 respectively, so as to provide a restoring force for the sliding seats 25 when they slide close to the gripping device 1. The elastic elements 27 can be tension springs, compression springs, etc. In this embodiment, the elastic element 27 is a tension spring. A vertically extending connecting rod 28 is fixedly provided on the movable seat 21, and one end of the elastic element 27 is hooked onto the connecting rod 28.

[0028] A connecting part 29 is also provided on the sliding seat 25. The push rod 26 has a "T"-shaped head 261. The connecting part 29 has a "C"-shaped hook structure in the horizontal direction. The connecting part 29 is configured so that the head 261 of the push rod 26 can enter or exit the connecting part 29 by the vertical movement of the moving seat 21, thereby realizing the linkage connection or separation between the push rod 26 and the sliding seat 25. In this way, the push rod 26 can switch the connection with different sliding seats 25. In this embodiment, the elastic element 27 is used to restore the movement of the sliding seat 25, and the connecting part 29 is used to engage and disengage with the push rod 26. This ensures that only the sliding seat 25 in the position directly opposite the gripping device 1 can be linked by the push rod 26, and also avoids interference with the push rod 26 when the moving seat 1 moves up and down.

[0029] This embodiment also includes a detector 4, which is positioned corresponding to the gripping device 1 to detect whether the threading tube 23 has been switched to a position facing the gripping device 1, thereby accurately activating the push rod 26. The detector 4 can be implemented using any proximity sensor, such as a photoelectric sensor.

[0030] Although the present invention has been specifically shown and described in conjunction with preferred embodiments, those skilled in the art should understand that any changes in form and detail made to the present invention without departing from the spirit and scope of the present invention as defined in the appended claims fall within the protection scope of the present invention.
