When the handle continues to rotate, the second connecting rod has a backward pulling force on the movable plate. When the two clamping strips have no clamping effect on the metal wire, the concave surface on the surface of the movable plate gradually approaches the inclined surface, and the bevel at the end of the concave surface has a certain squeezing effect on the inclined surface. At this time, the movable hammer will squeeze toward the middle of the flat groove with the rotating shaft as the center, thereby completing the cutting of the metal wire; S3. The cut metal wire will be retained in the second wire groove. When the second connecting rod pulls the movable plate backward, the L-shaped push block will also move backward. At the same time, under the action of the connecting groove, the pushing column will drive the bottom end of the swing rod to move backward.

At this time, the first wire groove 18 is connected with the second wire groove, so that the metal wire transmitted to the front will move into the second wire groove. When the metal wire is cut, the cut metal wire will remain in the second wire groove. When the second connecting rod 16 pulls the movable plate 6 backward, the L-shaped push block 30, the push column 29 and the swing rod 27 will all move backward.

[0025] A method for using a metal wire segmenting device for current collector production, the method steps are as follows: S1. First, the staff passes the metal wire surface through the conveying mechanism 2 and clamps it in the first wire groove 18, then starts the stepper motor inside the protruding platform 7. When the stepper motor drives the turning handle 12 to rotate, the movable groove 13 at the other end of the turning handle 12 will push the extending column to move. At the same time, under the cooperation of the frame 8 and the slide bar 10, the rotation of the turning handle 12 will cause the clamping bar 15 to move as a whole in a rectangular track, so that the two clamping bars 15 can clamp the metal wire in the process of moving to the front of the device and push the metal wire forward. This structure allows the metal wire to move forward in a step-by-step manner. At the same time, under the cooperation of the second connecting rod 16 and the movable plate 6, the rotation of the turning handle 12 will also cause the movable plate 6 to slide on the surface of the fixed platform 5; S2. When the handle 12 rotates and the two clamping strips 15 push the metal wire forward, the second connecting rod 16 has a forward thrust on the movable plate 6, and the concave surface on the surface of the movable plate 6 gradually moves away from the inclined surface 22. At this time, the elastic force of the spring 24 will push the movable hammer 20 to the outside of the flat groove 19, and the movable hammer 20 will open to the outside of the flat groove 19 with the rotating shaft as the center. When the handle 12 continues to rotate, the second connecting rod 16 has a backward pulling force on the movable plate 6. When the two clamping strips 15 have no clamping effect on the metal wire, the concave surface on the surface of the movable plate 6 gradually approaches the inclined surface 22, and the bevel at the end of the concave surface has a certain squeezing effect on the inclined surface 22. At this time, the movable hammer 20 will squeeze toward the middle of the flat groove 19 with the rotating shaft as the center, thereby completing the cutting of the metal wire; S3. The cut metal wire will be retained in the second wire groove. When the second connecting rod 16 pulls the movable plate 6 backward, the L-shaped push block 30 will also move backward.

Finally, under the action of the central column 28, the top end of the swing rod 27 will move in the other direction, and the movable platform 25 will drive the cut metal wire to move to the front of the device to facilitate the staff to take the metal wire.

[0026] Working principle: First, the staff passes the metal wire surface through the conveying mechanism 2 and clamps it in the first wire groove 18, then starts the stepper motor inside the protruding platform 7. When the stepper motor drives the turning handle 12 to rotate, the movable groove 13 at the other end of the turning handle 12 will push the extending column to move. At the same time, with the cooperation of the frame 8 and the slide bar 10, the rotation of the turning handle 12 will cause the clamping bar 15 to move as a whole in a rectangular trajectory, so that the two clamping bars 15 can clamp the metal wire in the process of moving to the front of the device and push the metal wire forward. This structure allows the metal wire to move forward in a step-by-step manner. At the same time, with the cooperation of the second connecting rod 16 and the movable plate 6, the rotation of the turning handle 12 will also cause the movable plate 6 to move on the surface of the fixed platform 5. The sliding structure enables the metal wire to move forward in a step-by-step manner, reduces manual intervention, and improves production efficiency, and is particularly suitable for large-scale, continuous production scenarios. Then, when the turning handle 12 rotates, the two clamping strips 15 push the metal wire forward, and the second connecting rod 16 has a forward thrust on the movable plate 6, and the concave surface on the surface of the movable plate 6 gradually moves away from the inclined surface 22.

When the turning handle 12 continues to rotate, the second connecting rod 16 has a backward pulling force on the movable plate 6. When the two clamping strips 15 have no clamping effect on the metal wire, the concave surface on the surface of the movable plate 6 gradually moves away from the inclined surface The movable hammer 20 will squeeze the middle part of the flat groove 19 with the rotating shaft as the center, so as to complete the cutting of the metal wire. Then, when the movable plate 6 moves toward the front of the device, the L-shaped push block 30 will also move forward. At the same time, under the action of the connecting groove 31, the pushing column 29 will drive the bottom end of the swing rod 27 to move forward. Finally, under the action of the center column 28, the top end of the swing rod 27 will move in the other direction. The movable platform 25 will be close to the front end of the T-shaped seat 17. At this time, the first wire groove 18 is connected with the second wire groove, so that the metal wire transmitted forward will move to the inside of the second wire groove. When the metal wire is cut off, The cut metal wire will be retained in the second wire groove. When the second connecting rod 16 pulls the movable plate 6 backward, the L-shaped push block 30 will also move backward. At the same time, under the action of the connecting groove 31, the pushing column 29 will drive the bottom end of the swing rod 27 to move backward. Finally, under the action of the central column 28, the top end of the swing rod 27 will move in the other direction, and the movable platform 25 will drive the cut metal wire to move to the front of the device to facilitate the staff to take the metal wire.

8. A method for using a metal wire segmenting device for current collector production, using the above claim 7, the method steps are as follows: S1. First, the staff passes the metal wire surface through the transmission mechanism (2) and clamps it in the first wire groove (18), and then starts the stepper motor inside the protruding platform (7). When the stepper motor drives the turning handle (12) to rotate, the movable groove (13) at the other end of the turning handle (12) will push the extending column to move. At the same time, under the cooperation of the frame (8) and the slide bar (10), the rotation of the turning handle (12) will cause the clamping bar (15) to move as a whole in a rectangular track, so that the two clamping bars (15) can clamp the metal wire in the process of moving toward the front of the device and push the metal wire forward. This structure allows the metal wire to move forward in a step-by-step manner. At the same time, under the cooperation of the second connecting rod (16) and the movable plate (6), the rotation of the turning handle (12) will also cause the movable plate (6) to slide on the surface of the fixed platform (5); S2. When the handle (12) rotates and the two clamping strips (15) push the metal wire forward, the second connecting rod (16) exerts a forward thrust on the movable plate (6), and the concave surface on the surface of the movable plate (6) gradually moves away from the inclined surface (22). At this time, the elastic force of the spring (24) pushes the movable hammer (20) toward the outside of the flat groove (19), and the movable hammer (20) opens toward the outside of the flat groove (19) with the rotating shaft as the center. When the handle (12) continues to rotate, the second connecting rod (16) exerts a backward pulling force on the movable plate (6). When the two clamping strips (15) have no clamping effect on the metal wire, the concave surface on the surface of the movable plate (6) gradually approaches the inclined surface (22), and the oblique angle at the end of the concave surface has a certain squeezing effect on the inclined surface (22). At this time, the movable hammer (20) squeezes toward the middle of the flat groove (19) with the rotating shaft as the center, thereby completing the cutting of the metal wire. S3. The cut metal wire will be retained in the second wire groove. When the second connecting rod (16) pulls the movable plate (6) backward, the L-shaped push block (30) will also move backward. At the same time, under the action of the connecting groove (31), the push column (29) will drive the bottom end of the swing rod (27) to move backward. Finally, under the action of the central column (28), the top end of the swing rod (27) will move in the other direction. The movable platform (25) will drive the cut metal wire to move to the front of the device to facilitate the staff to take the metal wire.
