Description

Technical Field

[0001] This application relates to the field of mechanical automation technology, specifically to a clamping device for wire terminals. Background Technology

[0002] Automotive wiring harnesses have terminals at one end and two wires leading out from the terminals at the other end. These two wires need to be wrapped with tape to form a wiring harness. In the traditional method, the terminal and the end of the wiring harness are often held manually and moved inside a wrapping machine. During the movement, the wrapping machine rotates around the wiring harness with tape to wrap the tape around it. Because the speed of the manual movement can vary at any time, it will lead to uneven overlap of the wiring harness during the wrapping process. When the movement is slow, there will be more overlap in the corresponding area, and when the movement is fast, there will be less overlap in the corresponding area. Areas with more overlap may be too thick, affecting the heat dissipation effect during installation or use in the vehicle; areas with less overlap will not provide sufficient protection for the wires and will be easily worn by friction or environmental factors.

[0003] With the development of automation, some wire harnesses have achieved automatic winding. However, the poor compatibility of terminal installation and clamping for wire harnesses of different specifications is also a technical challenge that needs to be solved. For example, the length of wire harnesses varies for different vehicle models or functional modules. Traditional clamping devices usually adopt a fixed positioning structure, which cannot quickly respond to changes in wire harness length. Frequent replacement of tooling fixtures is required, resulting in low production efficiency and increased costs. Summary of the Invention

[0007] The rotation axis of the turntable is parallel to the mounting platform and is used to drive the wire harness to rotate.

[0008] The positioning seat has a positioning groove for mounting terminals and is slidably connected to the turntable via a sliding plate, with the sliding direction parallel to the rotation axis of the turntable.

[0009] The slide plate is also provided with a gripper cylinder corresponding to the positioning groove, which is used to clamp the terminal in the positioning groove;

In addition, with the detection of the sensing sensor, the position information can be shared with the winding device, thereby achieving precise winding of the wire harness.

The slot 310 is also provided with a gripper cylinder 330 for clamping the terminal in the positioning slot 310; the end face of the turntable 110 is provided with a matching slide block 120 corresponding to the slide plate 320 for sliding connection with the slide plate 320; the bottom of the slide block 120 is provided with a positioning pin 121 and a sensing sensor 122 respectively corresponding to the slide plate 320; the bottom of the slide plate 320 is provided with a plurality of positioning holes 321 for pin connection corresponding to the positioning pin 121, and a plurality of blocking bolts 322 for triggering corresponding to the sensing sensor 122.

[0048] In this embodiment, the base 100 is fixedly installed on the mounting platform 200 and located at one end of the mounting platform 200, for positioning and connecting with the terminals on the wire harness and driving rotation; at the same time, the other end of the mounting platform 200 is also provided with a wire clamping assembly for connecting with the wires of the wire harness and driving rotation, so that the wire harness can be kept in a horizontal state and rotated, thereby cooperating with the tape winding mechanism for automatic winding.

[0049] In this embodiment, the positioning base 300 is provided with a matching positioning groove 310 for the corresponding terminal, so that it can be quickly and accurately connected to the terminal; and then it is connected to the base 100 through the sliding plate 320 and the turntable 110, so that the terminal can be rotated by the rotation of the turntable 110, and the distance between it and the wire clamping assembly can be achieved by the sliding connection of the sliding plate 320, thus making it suitable for wire harnesses of different lengths.

[0050] In this embodiment, the gripper cylinder 330 is fixedly mounted on the slide plate 320, so that it can slide synchronously with the positioning seat 300 and rotate synchronously with the positioning seat 300.
