[0022] Since the driving cylinder 14, the positioning cylinder 7, the limiting cylinder 10 and the motor 5 are all controlled by the controller (the functions and structures of the controller and other conventional devices are well known in the art, and the connection setting is also well known, so no further description is given here, and the controller is not shown in the drawings), when the pre-stranding wire 101 needs to be grouped online, the operator first places the grouping frame 1 to the output end of the cutting machine 18, and then starts the motor 5 through the controller to adjust the height of the grouping frame 1 under the rotation of the motor 5 driven by the screw rod 4, to ensure that the guide channel 301 of the guide plate 3 is in communication with the output end of the cutting machine 18, so that the pre-stranding wire 101 conveyed by the cutting machine 18 can enter the V-shaped containing space under the guidance of the guide channel 301, and then according to the set length of the pre-stranding wire 101, the positioning frame 8 and the limiting frame 11 are adjusted to the appropriate position by the slider rail pair and fixed, and then the limiting cylinder 10 is controlled to extend the piston rod through the controller, so that the limiting plate 9 moves in the vertical direction until it is clamped in the grouping groove 2, at this time, the pre-stranding wire 101 will make its end head resist against the limiting plate 9 under the conveying of the cutting machine 18, and then the cutting machine 18 is controlled to cut the pre-stranding wire 101 through the controller (the cutting machine is a rotary cutting machine, and the working principle of the rotary cutting machine can be found in Chinese patent CN120038253A - a rotary cutting machine, which is not described here), while cutting the pre-stranding wire 101, the positioning cylinder 7 is controlled to extend the piston rod through the controller, so that the positioning plate 6 moves in the vertical direction until the cut pre-stranding wire 101 is positioned and pressed tightly, so that the pre-stranding wire 101 remains in the V-shaped containing space while being cut, and the pre-stranding wire 101 also changes its spiral direction while being pressed, then the positioning cylinder 7 is controlled to retract the piston rod, so that the positioning plate 6 releases the pre-stranding wire 101 remaining in the V-shaped containing space, at the same time, the cutting machine 18 continues to convey the pre-stranding wire 101, at this time, the newly entered pre-stranding wire 101 will avoid the spiral end head of the cut pre-stranding wire 101, start from the correct position, and realize perfect side-by-side winding grouping with the remaining part (as shown in Figure 8 and Figure 9 ), which ensures the flatness and quality of the grouping joint, thereby realizing continuous grouping with high quality, until the end of the newly entered pre-stranding wire 101 resists against the limiting plate 9, and then the cutting machine 18 is controlled to cut it, and so on, until the grouping is completed, then the limiting cylinder 10 is controlled to retract the piston rod through the controller, so that the limiting plate 9 releases the pre-stranding wire 101 after grouping, at the same time, the driving cylinder 14 is controlled to retract the piston rod through the controller, so that the movable plate 202 moves away from the fixed plate 201, at this time, the pre-stranding wire 101 after grouping will naturally fall to the discharge frame (i.e. the angle steel 12) under the action of gravity, until it stays in the hook part 1201, and the driving cylinder 14 will extend the piston rod at the moment of falling of the pre-stranding wire 101, so that the movable plate 202 approaches the fixed plate 201 again, preparing for the online grouping of the next group of pre-stranding wires 101.

[0023] When the pre-stranded wire 101 of different heights and different specifications needs to be grouped online, the operator can drive the screw rod 4 to rotate by the motor 5 to adjust the height of the grouping frame 1 (since the pre-stranded wire has different forming pitch and forming height, the adjustment can be realized by lifting the grouping frame), so that the pre-stranded wire 101 of different forming height and different specifications can be grouped online; when the pre-stranded wire 101 of different lengths needs to be grouped online, the operator can adjust and fix the positioning frame 8 and the limiting frame 11 to the required position through the slider rail pair, so that the pre-stranded wire 101 of different lengths can be grouped online.
