A wire pulling cylinder 320 is provided on the second workbench 300. The wire pulling cylinder 320 is driven and connected to the wire pulling clamp 330.Specifically, after the first end of the wire harness 500 has completed the terminal process, the wire clamp 330 is first driven by the wire cylinder 320 to clamp the wire harness 500, and the second driver 310 drives the second workbench 300 to move backward to pull the wire harness 500 to a predetermined length, and the wire shearing mechanism of the stranding device cuts the wire harness 500; then the first driver 101 drives the first pneumatic finger 120 on the first workbench 110 to move forward to approach the wire harness 500. 0, so that the first wire selection clamp 140 reaches the position of the wire harness 500, and then the first pneumatic finger 120 drives the first wire selection clamp 140 to clamp each first wire to be twisted 510, the wire clamp 330 releases the wire harness 500, and the first driver 101 drives the first wire selection clamp 140 to move backward 540 to pull the first wire to be twisted 510 backward for a distance, so that the two ends of each first wire to be twisted 510 and each second wire to be twisted 520 are staggered to form a long and short wire; then the first wire selection clamp 140 releases the clamping state of the first wire to be twisted 510, the second driver 310 drives the wire clamp to move forward 530 to make the wire clamp reach the position of the wire harness 500, and then the wire cylinder 320 drives the wire clamp 320 to re-clamp each first wire to be twisted 510 and each second wire to be twisted 520, the second driver 310 drives the wire clamp to move backward 540 to pull the second end of each first wire to be twisted 510 and each second wire to be twisted 520 to a position flush with the terminal device; then through The first driver 101 drives the second clamping jaw 150 to move to the front of the wire pulling clamp 320, and the second pneumatic finger 130 drives the second wire selection clamping jaw 150 to clamp each second wire to be twisted 520, and then the first driver 101 drives the second clamping jaw 150 to move backward, so that each second wire to be twisted 520 is squeezed and bent, and the second end of each second wire to be twisted 520 is flush with the second end of each first wire to be twisted 510, thereby facilitating the terminal terminal process of the second end of each wire harness 500. It should be noted that, in this embodiment, the first driver 101 is a linear module, and the second driver 310 is a linear module. Among them, the wire pulling clamp 330 can clamp multiple wire harnesses 500 at the same time, which simplifies the complexity of the process of pulling each wire harness 500, thereby reducing the time of pulling the wire harness 500.
[0032] In order to improve the effect of clamping each first stranded wire 510. In one embodiment, Figure 3 and Figure 4As shown, the first wire selection clamp 140 includes: a first upper wire selection clamp 141 and a first lower wire selection clamp 142, the first pneumatic finger 120 is driven and connected to the first upper wire selection clamp 141 and the first lower wire selection clamp 142, the first upper wire selection clamp 141 and the first lower wire selection clamp 142 are arranged facing each other, and the first pneumatic finger 120 drives the first upper wire selection clamp 141 and the first lower wire selection clamp 142 to move toward each other. Specifically, the first upper wire selection clamp 141 and the first lower wire selection clamp 142 are aligned with each other, and the first upper wire selection clamp 141 and the first lower wire selection clamp 142 are driven by the wire pulling cylinder 320 to approach each other, so that the first wire to be twisted 510 can be clamped.
[0033] In one embodiment, Figure 3 and Figure 4 As shown, the first upper wire selection clamp 141 is provided with a plurality of first upper wire avoidance grooves 1411 facing downwards at intervals, and the first lower wire selection clamp 142 is provided with a plurality of first lower wire avoidance grooves 1421 facing upwards at intervals, and each of the first upper wire avoidance grooves 1411 and each of the first lower wire avoidance grooves 1421 is aligned vertically. Specifically, each of the first upper wire avoidance grooves 1411 and each of the first lower wire avoidance grooves 1521 is aligned vertically with each of the second wires to be twisted 520. When the first pneumatic finger 120 cooperates with the first driver to stretch the first upper wire selection clamp 141 and the first lower wire selection clamp 142 to clamp the first wire to be twisted 510, each of the second wires to be twisted 520 falls into the first upper wire avoidance grooves 1411 and the first lower wire avoidance grooves 1421, which can prevent the second wires to be twisted 520 of the wiring harness 500 from moving along with the first wire to be twisted 510, so that the first wire selection clamp 140 can only drive the first wire to be twisted 510 to move and form long and short wires.
[0034] In order to further enhance the ability to clamp the second to-be-twisted wire 520. In one embodiment, Figure 4 As shown, the second wire selection clamp 150 includes: a second upper wire selection clamp 151 and a second lower wire selection clamp 152, the second pneumatic finger 130 is driven and connected to the second upper wire selection clamp 151 and the second lower wire selection clamp 152, the second upper wire selection clamp 151 and the second lower wire selection clamp 152 are arranged vertically opposite to each other, and the second pneumatic finger 130 drives the second upper wire selection clamp 151 and the second lower wire selection clamp 152 to move toward each other. Specifically, the second upper wire selection clamp 151 and the second lower wire selection clamp 152 are driven by the second pneumatic finger 130 to approach each other and can clamp the second wire to be twisted 520.
[0035] In one embodiment, Figure 4As shown, a plurality of second upper wire avoiding grooves 1511 facing downward are spaced apart on the second upper wire selecting clamp 151, and a plurality of second lower wire avoiding grooves 1521 facing upward are spaced apart on the second lower wire selecting clamp 152, and each second upper wire avoiding groove 1511 and each second lower wire avoiding groove 1521 are aligned vertically. Specifically, each second upper wire avoidance groove 1511 and each second lower wire avoidance groove 1521 are aligned with each first wire to be twisted 510 up and down. When the second pneumatic finger 130 drives the second upper wire selection clamp 151 and the second lower wire selection clamp 152 to clamp each second wire to be twisted 520, each first wire to be twisted 510 falls into the second upper wire avoidance groove 1511 and the second lower wire avoidance groove 1521, which can prevent the first wire to be twisted 510 from moving with the second wire to be twisted 520, so that the second wire selection clamp 150 can only drive the second wire to be twisted 520 to move, so that the second wire to be twisted 520 is squeezed and bent, so that the second ends of the first wire to be twisted 510 and the second wire to be twisted 520 are aligned.
[0036] In one embodiment, Figure 1 and Figure 7 As shown, the second driver 310 includes a driving motor and a conveyor belt 3101. The driving motor is connected to the conveyor belt 3101, and the second workbench 300 is fixedly connected to the conveyor belt 3101. The second driver 310 can drive the conveyor belt 3101 to drive the wire pulling clamp 300 on the second workbench 300 to slide on the second mounting frame 200, so that the wire pulling clamp 330 can pull the wire harness 500 in batches.
[0037] In order to improve the clamping effect of each wire harness 500. In one embodiment, Figure 5 and Figure 6 As shown, the wire pulling clamp 330 includes an upper clamping member 3301 and a lower clamping member 3302. The wire pulling cylinder 320 is driven and connected to the upper clamping member 3301 and the lower clamping member 3302. A clamping cavity 3303 is formed between the upper clamping member 3301 and the lower clamping member 3302. Specifically, the wire pulling cylinder 320 can be used to drive the upper clamping member 3301 and the lower clamping member 3302 to move closer to each other to clamp each wire harness 500. It should be noted that the first wire selection clamp 140 and the second wire selection clamp 150 can be movably arranged in the clamping cavity 3303. When the first driver 101 drives the first wire selection clamp 140 and the second wire selection clamp 150 to move forward and approach the wire harness 500, the wire pulling cylinder 320 drives the wire pulling clamp 330 to open, so that the first wire selection clamp 140 can smoothly pass through the clamping cavity 3303 to stretch the first wire to be twisted 510 and the second wire to be twisted 520. It should be noted that the second wire selection clamp 150 should be in front of the wire pulling clamp 330 when pulling the wire. At this time, the wire pulling clamp 330 should not need to be opened, and the wire pulling clamp 330 should be in a clamped state.
[0038] In order to improve the overall flexibility of the stretched short line structure when used. In one embodiment, Figure 7 As shown, the second mounting frame 200 further includes: a plurality of sub-mounting frames 201, each of which is detachably connected to the other. Specifically, because the sub-mounting frames 201 are detachably connected, different numbers of sub-mounting frames 201 can be spliced together according to production requirements, thereby flexibly adjusting the sliding distance of the second workbench 300, allowing the wire pulling clamp 330 to pull wire harnesses 500 of different lengths according to production requirements.
[0039] In order to avoid the motion interference between the wire pulling clamp 330 and the first wire selecting clamp 140 and the second wire selecting clamp 150. In one embodiment, as Figure 1 As shown, a sliding assembly 160 is provided on the first placement platform 100. The sliding assembly 160 is slidably disposed on the first placement platform 100, and the first pneumatic finger 120 and the second pneumatic finger 130 are both connected to the sliding assembly 160. Specifically, the sliding assembly 160 includes a sliding frame 161 and a third driver 162. The sliding frame 161 is slidably disposed on the first workbench 110, and the third driver 162 is disposed on the first workbench 110. The third driver 162 is drivingly connected to the sliding frame 161, and the first pneumatic finger 120 and the second pneumatic finger 130 are disposed on the sliding frame 161. When the wire pulling clamp 330 is pulling the wire alone, the third driver 400 drives the sliding frame 161 to move away from the clamping cavity 3303, and the first wire selection clamp 140 and the second wire selection clamp 150 withdraw from the second clamping cavity 3303, thereby preventing motion interference between the wire pulling clamp 330 and the first wire selection clamp 140 and the second wire selection clamp 150. In this embodiment, the third driver 161 is a linear module.
[0040] It should be noted that the types of the first driver 101, the second driver 310 and the third driver 162 are not limited by this embodiment. They can be drive motors, electric push rods or linear modules, etc., as long as they can drive the components connected to them to achieve the corresponding movement effect.

A person skilled in the art will be able to make other variations or modifications based on the above description. It is not necessary and impossible to enumerate all implementation methods here.
