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, threading rain plugs, crimping terminals and plugging connectors. Wiring harnesses are generally divided into single wires and twisted pairs. Twisted pair wires are generally composed 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 double twisted 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 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 the single wire on a fully automatic offline crimping and insertion machine to form a single semi-finished wire harness, and then completing the main processes of fully automatic wire feeding, zero cutting, stripping, plugging, crimping terminals, twisting and tape wrapping for the twisted pair on a fully automatic offline twisting machine to form a semi-finished wire harness for the twisted pair, and then circulate to the finished wire harness insertion area, where the semi-finished twisted pair harness is manually inserted into the single semi-finished wire harness to form a finished wire harness. The turnover time is long, the production efficiency is low, the quality consistency is low, and it cannot meet the production requirements. In view of this, it is necessary to provide a wire double-wire twisting device mounted on the fully automatic offline crimping and insertion machine to overcome the above-mentioned defects, thereby realizing flexible and fully automated processing of single and twisted pairs.

To achieve the above synchronous movement relationship, please refer to Figure 1 and Figure 2 The two moving ends of the second linear motion module 101 are respectively provided with a left translation carrier 102 and a right translation carrier 103. The left rotating wire twisting mechanism 7 and the left tape point winding mechanism 9 are both arranged on the left translation carrier 102, and the right rotating wire twisting mechanism 8 and the right tape point winding mechanism 10 are both arranged on the right translation carrier 103.

[0044] As a preferred embodiment, the left wire storage mechanism 5 and the right wire storage mechanism 6 are both fixed on the frame of the driving translation mechanism 1. The lifting and transfer reversing device 2 is arranged below the driving translation mechanism 1.

[0045] Based on the above equipment, the present invention also proposes a wire double-wire twisting process, see Figure 1 、 Figure 2 、 Figure 3 and Figure 15 The process is implemented based on the above-mentioned equipment and includes the following steps:

[0046] Step S1, the lifting transfer reversing device 2 receives the wires B1 and B2 conveyed by the upward clamping and conveying device from the transfer position a;

[0047] Step S2, the lifting and handover reversing device 2 drives the wires B1 and 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;

[0049] Step S4, the left wire conveying mechanism 3 clamps the left ends of the wires B1 and B2, and the right wire conveying mechanism 4 clamps the right ends of the wires B1 and B2;

[0050] Step S5: The left wire conveying mechanism 3 and the right wire conveying mechanism 4 move synchronously to convey the left ends of the wires B1 and B2 to the left wire storage mechanism 5, and convey the right ends of the wires B1 and B2 to the right wire storage mechanism 6;

[0051] In step S6, the left-hand wire conveying mechanism 3 receives the left end of the twisted pair (A1 & A2) twisted in the previous process from the left-hand rotating twisting mechanism 7, and the right-hand wire conveying mechanism 4 receives the right end of the twisted pair (A1 & A2) twisted in the previous process from the right-hand rotating twisting mechanism 8;

[0052] In step S7, the lifting and handover reversing device 2 receives the twisted pair wires twisted in the previous process from the left wire conveying mechanism 3 and the right wire conveying mechanism 4, and drives the twisted pair wires to the handover position a for the upward clamping and conveying device to receive the twisted pair wires;

[0053] In step S8, the left wire-pulling conveying mechanism 3 clamps the left ends of the wires B1 and B2 from the left wire-storing mechanism 5 and conveys them to the left-rotating wire-twisting mechanism 7, and the right wire-pulling conveying mechanism 4 clamps the right ends of the wires B1 and B2 from the right wire-storing mechanism 6 and conveys them to the right-rotating wire-twisting mechanism 8.

[0054] Step S9: The left-hand twisting mechanism 7 and the right-hand twisting mechanism 8 respectively clamp the left and right ends of the wire B1 and the wire B2, and the left-hand twisting mechanism 7 and the right-hand twisting mechanism 8 synchronously rotate to twist the wires B1 and B2 into a twisted pair.

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

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

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

[0058] Regarding the preferred reversing action of the lifting and transfer reversing device 2, in step S3 of this embodiment, the lifting and transfer reversing device 2 drives the left ends of the wires B1 and B2 to rotate at a preset angle and then align with the left wire conveying mechanism 3, and at the same time drives the right ends of the wires B1 and B2 to rotate at a preset angle and then align with the right wire conveying mechanism 4.

[0059] Regarding the specific twisting action, in step S9 of this embodiment, according to the length of the wire B1 and the wire B2, the left-rotating twisting mechanism 7 clamps the left ends of the wire B1 and the wire B2 and moves to the left initial twisting position, and the right-rotating twisting mechanism 8 clamps the right ends of the wire B1 and the wire B2 and moves to the right initial twisting position, after which the left-rotating twisting mechanism 7 and the right-rotating twisting mechanism 8 synchronously perform rotational motion.

[0060] In a preferred embodiment of the present invention, Figures 4 to 9 As shown, the lifting and transfer reversing device 2 includes a lifting and translational motion component 20, the moving end of which is provided with a reversing support plate 21, on which are provided a left rotating arm 22, a right rotating arm 23, a left reversing drive component 24, and a right reversing drive component 25. The first end of the left rotating arm 22 and the first end of the right rotating arm 23 are respectively rotatably connected to the reversing support plate 21, the second end of the left rotating arm 22 is provided with a first clamping component 220 and a second clamping component 221, and the second end of the right rotating arm 23 is provided with a third clamping component 230 and a fourth clamping component 231. The left reversing drive component 24 is used to drive the left rotating arm 22 to rotate by a preset angle, and the right reversing drive component 25 is used to drive the right rotating arm 23 to rotate by a preset angle, so that the second end of the left rotating arm 22 and the second end of the right rotating arm 23 are moved closer to or away from each other. Among them, the reversing support plate 21 and the various components and members thereon constitute a clamping and reversing mechanism.

[0061] In the above structure, the lifting and translation motion component 20 is used to drive the reversing support plate 21 to rise, fall or move forward and backward. When the device transfers the wires from the upward wire clamping and conveying device, the first wire clamping component 220 and the third wire clamping component 230 transfer the clamping wire B1 to rise and avoid the position, and then the second wire clamping component 221 and the fourth wire clamping component 231 transfer the clamping wire B2. Afterwards, under the driving action of the left reversing drive component 24 and the right reversing drive component 25, the left rotating arm 22 and the right rotating arm 23 simultaneously rotate in opposite directions, thereby driving the left ends of the wires B1 and B2 to move to align with the left wire pulling conveying mechanism, and driving the right ends of the wires B1 and B2 to move to align with the right wire pulling conveying mechanism. Based on the above principle, the present invention realizes the mutual conversion between U-shaped wire clamping and coaxial wire clamping, which can effectively improve the wire handling efficiency.

[0065] When the lifting and transfer reversing device receives the wires B1 and B2, the left rotating arm 22 and the right rotating arm 23 are preferably in a state of being close to each other. In this regard, in this embodiment, the reversing support plate 21 is provided with a left accommodating opening 214 and a right accommodating opening 215 that are symmetrical on both sides. The left rotating arm 22, the first wire clamping assembly 220, the second wire clamping assembly 221 and the left lifting cylinder assembly 222 are located in the left accommodating opening 214, and the right rotating arm 23, the third wire clamping assembly 230, the fourth wire clamping assembly 231 and the right lifting cylinder assembly 232 are located in the right accommodating opening 215.

[0066] As a preferred embodiment, the left reversing drive assembly 24 drives the left rotating arm 22 to rotate at an angle of 90°, and the right reversing drive assembly 25 drives the right rotating arm 23 to rotate at an angle of 90°. However, in actual application, 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 rotation of the rotating arm. Specifically, the left reversing drive assembly 24 includes a left reversing drive cylinder 240 and a left reversing pendulum block 241. The left reversing pendulum block 241 is transmission-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. The right reversing pendulum block 251 is transmission-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 be driven by a linear module. Specifically, the lifting and translational motion assembly 20 includes a linear lifting module 200. The moving end of the linear lifting module 200 is provided with a bearing plate 201. The bearing plate 201 is slidably connected to a slide rail assembly 202. The reversing support plate 21 is fixed to the end of the slide rail assembly 202. The bearing plate 201 is provided with a motor drive assembly 203 for driving the slide rail assembly 202 to move in translation. Furthermore, the motor drive assembly 203 and the slide rail assembly 202 are connected by a belt assembly 204.

[0069] In another preferred embodiment of the present invention, a translational wire pulling and storing device is included, combined with Figures 10 to 14As shown, the translational wire pulling and storing device includes a driving translation mechanism 1, a left wire pulling conveying mechanism 3, a right wire pulling conveying mechanism 4 having the same structure as the left wire pulling conveying mechanism 3, a left wire storing mechanism 5 corresponding to the left wire pulling conveying mechanism 3, and a right wire storing mechanism 6 corresponding to the right wire pulling conveying mechanism 4.
