Description

Technical Field

[0001] The invention relates to a wire processing device, in particular to a wire double-wire twisting device and process. Background Art

[0002] In the automotive wiring harness industry, the processing of wiring harnesses involves major processes such as wire feeding, zero cutting, stripping, rain plug insertion, crimping terminals and plug connectors. Wire harnesses are generally divided into single wires and twisted pair wires. Twisted pair wires are generally made of two wires twisted together at a certain pitch. They have a certain anti-interference effect and can also improve the flexibility of the wires, thereby reducing the risk of wire breakage. At the same time, the cable structure with twisted double wires can improve the wear resistance and corrosion resistance of the wires and extend the service life of the wires.

[0003] In the prior art, the processing of finished wire harnesses containing single wires and twisted pairs can only be done by first completing the main processes of fully automatic wire feeding, zero cutting, stripping, plugging, crimping terminals and plugging connectors for single wires on a fully automatic offline crimping and insertion machine to form a single wire semi-finished wire harness, and then completing the main processes of fully automatic wire feeding, zero cutting, stripping, plugging, crimping terminals, twisting and dot-taping for twisted pairs on a fully automatic offline twisting machine to form a twisted pair semi-finished wire harness, and then circulate to the finished wire harness supplementary insertion area, and manually supplement the twisted pair semi-finished wire harness to the single wire semi-finished wire harness to form a finished wire harness, which has a long turnover time, low production efficiency, and low quality consistency, and cannot meet production requirements. In view of this, it is necessary to provide a wire double-wire twisting device mounted on a fully automatic offline crimping and insertion machine to overcome the above defects, thereby realizing flexible and fully automated processing of single wires and twisted pairs.

[0047] Step S2, the lifting and handover reversing device 2 drives the wire B1 and the wire B2 to move to the handover position b;

[0048] Step S3, the lifting and handover reversing device 2 drives the left ends of the wires B1 and B2 to move to align with the left wire pulling conveying mechanism 3, and drives the right ends of the wires B1 and B2 to move to align with the right wire pulling conveying mechanism 4;

[0054] Step S9, the left-rotating wire twisting mechanism 7 and the right-rotating wire twisting mechanism 8 clamp the left and right ends of the wire B1 and the wire B2 respectively, and the left-rotating wire twisting mechanism 7 and the right-rotating wire twisting mechanism 8 synchronously perform rotational motion to twist the wire B1 and the wire B2 into a twisted pair;

[0055] Step S10, the left adhesive tape point wrapping mechanism 9 and the right adhesive tape point wrapping mechanism 10 respectively wrap adhesive tapes around the left and right ends of the twisted pair wires.

[0056] In the step S4 of the above process, after the left wire conveying mechanism 3 and the right wire conveying mechanism 4 clamp the left and right ends of the wire B1 and the wire B2 respectively, the lifting and handover reversing device 2 moves upward and waits for the execution of the step S7;

[0057] When the step S6 is completed, the lifting and transfer reversing device 2 moves downward to the transfer position b, and then the step S7 is executed.

However, in actual applications, the rotation angles of the left rotating arm 22 and the right rotating arm 23 are not limited to right angles.

[0067] In this embodiment, a linkage mechanism consisting of a cylinder, a pendulum block, a connecting rod and a universal joint is preferably used to drive the rotating arm to rotate. Specifically, the left reversing drive assembly 24 includes a left reversing drive cylinder 240 and a left reversing pendulum block 241, and the left reversing pendulum block 241 is connected between the telescopic rod of the left reversing drive cylinder 240 and the left rotating arm 22. Similarly, the right reversing drive assembly 25 includes a right reversing drive cylinder 250 and a right reversing pendulum block 251, and the right reversing pendulum block 251 is connected between the telescopic rod of the right reversing drive cylinder 250 and the right rotating arm 23.

[0068] In this embodiment, the lifting and translational motion assembly 20 can realize lifting and translational drive through a linear module. Specifically, the lifting and translational motion assembly 20 includes a linear lifting module 200, a bearing plate 201 is provided at the moving end of the linear lifting module 200, and the bearing plate 201 is slidably connected with a slide rail assembly 202.
